  The portable digital vernier caliper with an enlarged side long region is a long object (eg, 3.5 m: see Patent Document 1, paragraph [0021]) with high accuracy (eg, 0.01 mm: see Patent Document 1, paragraph [0022]). Can be measured. However, there is a problem that the measurement work is troublesome because at least one sizing rod must be attached between the tip end portion of the guide beam and the stationery jaw depending on the dimension of the object to be measured. Further, when the size of the article is 1.5 m, for example, the size and mass of the vernier caliper increase, and a plurality of measurement workers are required. Therefore, labor saving was necessary in terms of product cost reduction.

  FIG. 1 shows the basic structure of a dimension measuring apparatus 10 of the present invention. The dimension measuring apparatus 10 mainly includes an elastic member 11, an elastic force applying means 25, and a laser distance measuring device 45.

  The telescopic member 11 has a first linear member 15 extending linearly and a second linear member 20 extending linearly attached to the first linear member 15 so as to be movable in the axial direction of the first linear member 15 as a whole. It is formed to be stretchable in the direction. The first linear member 15 has a cylindrical shape, and the second linear member 20 has a rod shape that fits slidably on the first linear member 15. The second linear member 20 may have a square cross-sectional shape, and the first linear member 15 may be a groove-shaped member having a square cross-sectional shape that fits slidably thereto. Further, the second linear member 20 is an inverted triangle with a cross-sectional shape pointing downward, and the first linear member 15 slidably fitted to the second linear member 20 is a cylindrical member having an inverted triangle.

In the embodiment shown in FIG. 2 and subsequent figures, the same reference numerals are used for the same members as those described in FIG. 1, and detailed descriptions of these members are omitted.
[First Embodiment]

  FIG. 2 is a first embodiment of the dimension measuring apparatus of the present invention, and an elastic force applying means 33 is schematically shown. FIG. 2A shows a state in which the spiral spring 34 is unloaded, that is, a state in which the second linear member 20 is accommodated in the first linear member 15 and no tension is applied to the wire 37. FIG. 2B shows a state in which the spiral spring 34 is under load, that is, a state in which the second linear member is pulled out from the first linear member 15 and tension is applied to the wire 37.

  An elastic force applying means 33 is provided in the housing 31 fixed to the rear end of the first linear member 15. The elastic force applying means 33 includes a spiral spring 34, and the end of the spiral spring 34 is fixed to the spring fixing shaft 35 and the tip is fixed to the inner peripheral surface of the bobbin 36. On the other hand, a wire 37 is connected to the rear end of the second linear member 20, and the wire 37 is wound around a bobbin 36 via a deflection roller 38.

  A braking / locking device 39 that presses the outer peripheral surface of the bobbin 36 to brake or lock the rotation of the bobbin 36, that is, expansion / contraction of the expansion / contraction member 11 is provided. The brake / locking device 39, for example, presses a shoe against the outer peripheral surface of the bobbin 36 with a screw shaft to stop or gradually move the linear member 15 or 20. Thereby, the damage by the collision with the to-be-measured object of both pressing members 21 and 25 is prevented. The magnitude of the pressing force of the shoe by the screw shaft is adjusted by rotating the screw shaft. When the spiral spring 34 shown in FIG. 2A is in an unloaded state, the shoe is not in contact with the outer peripheral surface of the bobbin 36, and the locking is released.

  FIG. 3 is an explanatory view of a dimension measuring process by the dimension measuring apparatus of the present invention. FIG. 3A shows a state before the measurement work. A measurement operator (not shown) holds the first linear member 15 in a state where the elastic member 11 is contracted (corresponding to FIG. 2A). Next, as shown in FIG. 3B, when the second linear member 20 is pulled out from the first linear member 15, a spring (not shown) of the elastic force applying means 25 expands, and the first linear member 15 and the second linear member 15 extend. The elastic force which pulls mutually between the linear members 20 is generated (corresponding to FIG. 2B). Next, when the front end side presser 21 is hooked and fixed on the front surface 2 of the object 1 to be measured, the first linear member 15 advances by elastic force, and the front end side presser 21 and the rear end side presser are moved as shown in FIG. 16 to be measured. In this sandwiched state, the distance from the front end side presser 21 to the presser surface 22 is measured by the laser distance measuring device 45. The value obtained by subtracting the horizontal linear distance d from the measured value 17 to the laser detection surface of the laser distance measuring device 45 is the dimension of the DUT 1. This horizontal linear distance d is automatically corrected by the laser distance measuring device 45. The distance d is a distance unique to the dimension measuring apparatus, is measured in advance for each dimension measuring apparatus, and is set in the laser distance measuring device 45.

In the above dimension measurement, the rear end side presser 16 is hooked and fixed to the rear surface 3 of the object 1 to be measured, and the front end side presser 21 is retracted by the elastic force, and the front end part presser 21 and the end part presser 16 are measured. May be sandwiched.
[Second Embodiment]

  FIG. 4 shows a second embodiment of the dimension measuring apparatus according to the present invention. The elastic force applying means 41 of the dimension measuring apparatus 40 includes a coil spring 42 and a spring receiving seat 43. The coil spring 42 has a tip fixed to the rear end of the second linear member 20 and a rear end fixed to the spring seat 43. The coil spring 42 is held in the first linear member 15 in an unloaded state. The spring seat 43 is fixed inside the rear end of the first linear member 15.

With the dimension measuring apparatus 40 configured as described above, the dimension of the object to be measured is measured as follows. A measurement operator (not shown) holds the first linear member 15 of the extendable member 11 and hooks the front end side presser 21 on the tip of the object to be measured. Next, the first linear member 15 is moved back by hand until the distance between the front end surface of the object to be measured and the rear end side pressing surface 17 becomes slightly larger than the dimension of the object to be measured. By this retreat, the coil spring 42 is extended, and an elastic force is generated between the first linear member 15 and the second linear member 20 so as to pull each other. Here, when the holding force of the first linear member 15 is loosened, only the first linear member 15 moves forward due to the elastic force, and the object to be measured is sandwiched between the front end side presser 21 and the rear end side presser 16. In this state, the distance from the front end side presser 21 to the reflection surface 23 (front end side presser surface 22) is measured. The value obtained by subtracting the horizontal linear distance d from this distance is the dimension of the object to be measured. In the second embodiment, the apparatus and method for measuring dimensions are greatly simplified as compared with those in the second embodiment.
[Third Embodiment]

  FIG. 5A and FIG. 5B show the extension member 51 of the present invention. The extension member 51 includes an extension pipe 52, an outer cap 55, a guide block 60, a connection pipe 70, and an extension shaft 72.

  The extension pipe 52 is slidably fitted inside the first linear member 15. The length is substantially the same as that of the first linear member 15, and the material is made of aluminum or the like or an alloy thereof.

  The outer cap 55 has a flange 57 that protrudes toward the inner diameter side at the tip of a cylindrical cap body 56. An inner side of the collar 57 is a shaft hole 58.

  The guide block 60 has a short cylindrical block body 61 fitted inside the extension pipe 52 with a clearance fit. In the guide block 60, a step 62 is formed at the front end of the block body 61, and a shaft connecting portion 63 projects forward. A wire 37 (see FIG. 2) is connected to the rear end of the block body 56.

  The connecting pipe 70 is fitted to the shaft connecting portion 63, and the rear end of the shaft connecting portion 63 is in contact with the step 62 of the guide block 55. The outer cap 55 is slidably fitted in the shaft hole 58 of the outer cap 55. An extension shaft 72 is fitted on the connecting pipe 70. A front end side presser 21 having a presser surface 22 and a reflective surface 23 is attached to the tip of the extension shaft 72. The outer cap 55 is provided with a braking / locking device 53 that brakes or locks the sliding of the guide block 55. For example, the brake / locking device 53 presses a shoe against the outer peripheral surface of the guide block 55 with a screw shaft to stop or gradually move the guide block 60. The magnitude of the pressing force of the shoe by the screw shaft is adjusted by rotating the screw shaft.

  FIG. 6 shows a three-stage dimension measuring device 50. As shown in FIGS. 6 (b) and 6 (c), the three-stage dimension measuring apparatus 50 has an extension member 51 sliding on the first linear member 15 instead of the second linear member 20 shown in FIG. It fits to be movable. The wire 37 extends rearward from the rear end of the guide block 55 (see FIG. 5) of the extension member 51, and the rear end portion of the wire 37 is wound around the bobbin 36 shown in FIG.

  The dimension measuring method by the three-stage dimension measuring apparatus 50 configured as described above is performed in the same manner as the two-stage dimension measuring apparatus shown in FIG. That is, FIG. 6A shows a state before the measurement work. A measurement operator (not shown) holds the three-stage dimension measuring device 50 in a state where the extension member 51 enters the first linear member 15 and is contracted. Next, as shown in FIG. 6 (b), the extension member 51 is pulled out from the first linear member 15, the front end side pressing surface 22 is hooked on the front end surface 6 of the measurement object 5, and a distance slightly longer than the dimension of the measurement object 5. Pull out only. As a result, as shown in FIG. 2B, the spiral spring 34 of the elastic force applying means 25 is rewound, and an elastic force that pulls between the first linear member 15 and the extension member 51 is generated. Next, when the holding force of the first linear member 15 is loosened, the first linear member 15 is advanced by the elastic force, and the front end side presser 21 and the rear end side presser 16 are measured as shown in FIG. Insert object 5. In this sandwiched state, the distance from the front end side presser 21 to the presser surface 22 is measured by the laser distance measuring device 45. A value obtained by subtracting the horizontal linear distance d from the rear end side pressing surface 17 to the laser detection surface of the laser distance measuring device 45 from this measured value is the dimension of the object 5 to be measured.

  Although the dimension measuring apparatus 50 is a three-stage type, the extension member 51 can be increased by one to form a four-stage dimension measuring apparatus, for example.

FIG. 7 is a side view showing the arrangement of the heat insulating members. A heat insulating member 75 is attached to each of the holding surface 22 in contact with the measured object surface 2 (6) of the front end side presser 21 and the holding surface 17 in contact with the measured object surface 3 (7) of the rear end side presser 16. . A heat insulating member 76 is inserted between the first linear member 15 and the laser distance measuring device 45. These heat insulating materials 75 and 76 can prevent the measurement member from being damaged by thermal radiation from the DUT 1 (5). For these heat insulating members 75 and 76, the heat insulating material is, for example, rock wool or ceramic, and the thickness is 2 mm.
[Fourth Embodiment]

  FIGS. 9 and 10 show a fourth embodiment of the dimension measuring apparatus of the present invention, and a first linear member 115 extending linearly and a straight line attached to the first linear member 115 so as to be movable in the axial direction thereof. The second linear member 120 extends in a shape, and the first linear member 115 functions as a rail so that the second linear member 120 moves. The 1st linear member 115 should just be a linear rod-shaped member, for example, can also use a linear rail. In the fourth embodiment, the elastic force applying means 33 described above is not provided, and the wire 37 is not attached to the second linear member 120. Therefore, as in the above-described example, the second linear member 20 does not slide with respect to the first linear member 15 and the overall length does not expand or contract.

  For example, the first linear member 115 and the second linear member 120 have a cross-sectional shape that is an inverted triangle so that a high-temperature airflow from a measured object such as a cast piece spreads upward along a slope of the inverted triangle. As a result, it is possible to prevent the device from being damaged due to heat, such as the laser distance measuring device 145 disposed above the first linear member 115.

  The first linear member 115 is provided with a rear end side presser 116 that presses the rear end side of the object to be measured, and the second linear member 120 is provided with a front end side presser 121. It has a light reflection surface 123 and a pressing surface 122 that is the same surface as the light reflection surface 123. The pressing surface 122 of the front end side presser 121 is provided so as to face the pressing surface 117 of the rear end side presser 116. The holding surfaces 117 and 122 are provided with heat insulating members 75 and 75 such as rock wool and ceramic so as to prevent the measurement member from being damaged by heat radiation. Note that a heat insulating member 76 may be provided between the first linear member 115 and the laser distance measuring device 145.

  The laser distance measuring device 145 is fixed to the upper surface of the first linear member 115, measures the distance to the front end side presser 121, and obtains the dimension between the front end side and the rear end side of the object to be measured. Specifically, the distance from the front end side presser 121 to the reflection surface 123 that is the same surface as the front end side presser surface 122 is measured, and the length of the object to be measured is measured.

  As shown in FIG. 10, for example, when the measurement operator w holds the first linear member 115 and hooks the front end side presser 121 on the front surface 2 of the DUT 1, the first linear member 115 and the second linear member 120. Relatively move, and the DUT 1 is sandwiched between the front end side presser 121 and the rear end side presser 116. In this sandwiched state, the laser distance measuring device 145 measures the distance to the reflective surface 123 that is the same surface as the presser surface 122 of the front end side presser 121. Since the laser distance measuring device 145 measures the distance of the front end side presser 121 from the presser surface 122, even if the second linear member 120 expands or contracts due to heat radiation or the like, the target is accurately measured. The dimension of the measurement object 1 can be measured.

  FIG. 8 shows a schematic diagram of an object measuring system 80 of the present invention. The DUT 1 is a slab.

  After completing the dimension measurement, a transmission switch (not shown) attached to the laser distance measuring device 45 is pushed. A dimension measurement value measured by the laser distance measuring device 45 is transmitted from a wireless transmitter 83 adjacent to the laser distance measuring device 45 through a network 76 such as Bluetooth Network (registered trademark), IEEE 802 or the like to a repeater 85 such as a PDA (mobile phone). To the information terminal) and further to the measurement management computer 82 provided in the cab. An object storage place (not shown) is provided, and the position of the object to be measured is set by the address recorded on the tag. The address can be read by an address discriminator (for example, a bar code scanner) 88 and the object to be measured placed in the object to be measured can be specified. The address identification means 87 may be a radio frequency identification (RFID) means instead of a barcode scanner. The repeater 85 is input by the dimension measurement value sent from the measurement value transmitter 83 and the measurement worker w and / or measured worker ID or address identification information sent from the address discriminator 88 or the address discriminating means 87. Individual identification information and the like are received, and these pieces of information are transmitted to the measurement management computer 82.

  The measurement management computer 82 receives the received work completion place No. Based on the measured value and the measurement worker ID, And the in-place measurement object specific information is transmitted to the measurement worker w through the repeater 85. Also, the dimension of the measured object in the online data is compared with the received dimension measurement value. Then, for example, the measurement management computer 82 transmits the collation result to the repeater 85 and notifies the worker w of the collation result and the like.
