[Configuration Example of Holding Device 100]

  FIG. 1 is a perspective view showing a configuration example of a holding device 100 according to the present invention. The holding device 100 holds both sides of a length measuring device 3 (see FIG. 5) slidably installed on a rail-like support body 2 and fixes it to the support body 2. The length measuring device 3 is an example of a moving body.

  A holding device 100 shown in FIG. 1 includes holders 1A and 1B and a support 2. The holders 1A and 1B are attached to the support 2, and hold the both sides of the length measuring device 3 shown in FIG. 5 to fix the length measuring device 3. The holders 1A and 1B include a main body 1a and a lever 1b. The main body 1a of the holder 1A and the main body 1a of the holder 1B are slidably attached to the support 2 and hold the length measuring device 3 (see FIG. 5) assembled to the support 2. The main body 1a is provided with a boss (projection) 10d and support portions 10e and 10e. The boss 10 d is fitted into a boss hole (not shown) of the length measuring device 3. The support portions 10e and 10e support the length measuring device 3 and keep the clearance between the support 2 and the length measuring device 3 constant. For example, the thickness of the support portions 10e and 10e is about 1 mm. The lever 1b is an example of an operation member and is rotatably attached to the main body 1a. The lever 1b is clamped with the support 2 sandwiched in cooperation with the main body 1a.

  FIG. 2 is an exploded perspective view showing a configuration example of the holder 1A (1B). In the holder 1A shown in FIG. 2, the lever 1b is removed from the main body 1a. The lever 1b includes a head 1c and a leg 1d. The leg 1d is formed in a non-circular shape, for example, a substantially parallelogram-like plate shape. The leg portion 1d has low portions 1k and 1k in which corners facing each other are partially cut. These low parts 1k and 1k ensure the space | interval of the leg part 1d and the support body 2. As shown in FIG. Thereby, since the support body 2 and the leg part 1d of holders 1A and 1B do not contact, the holders 1A and 1B attached to the support body 2 are easily slid. The leg portion 1d is provided with a connecting portion 1f that connects the leg portion 1d and the head portion 1c. The leg portion 1d and the connecting portion 1f are integrally formed.

  An operating head 1c is attached to the connecting portion 1f with screws 1g. On the head 1c, an operation gripping portion 1e is provided so as to project in the same direction as the transfer position for transferring the length measuring device 3. The user grasps the grip portion 1e and rotates the leg portion 1d of the lever 1b. Since the leg portion 1d and the grip portion 1e are fixed, the movements of the grip portion 1e and the leg portion 1d are synchronized. That is, when the grip portion 1e is rotated, the leg portion 1d is also rotated in the same direction.

  The lever 1b is rotatably attached to the mounting portion 1q of the main body 1a. For example, in a state where the leg portion 1d and the head portion 1c of the lever 1b are separated, the connecting portion 1f of the leg portion 1d is inserted into the hole portion 1i of the mounting portion 1q from the lower side of the main body 1a. After the insertion, the head 1c is fixed to the connecting portion 1f of the leg 1d with a screw 1g. At this time, it fixes so that the corner | angular part 1n of the leg part 1d and the holding part 1e of the head 1c may face the same direction. For example, the tip of the connecting portion 1f formed in a track shape is fitted into the hole of the head portion 1c formed in the same track shape. Thereby, it can fix so that the leg part 1d and the holding part 1e may face the same direction.

  The mounting portion 1q of the main body 1a is provided with slopes 1s and 1t, step portions 1y and 1z, and convex portions 1u and 1u. The convex portions 1u and 1u are provided so as to protrude from the plane of the mounting portion 1q. The concave portions 10a and 10a (see FIG. 3) of the lever 1b are locked to the convex portions 1u and 1u. In this example, the convex portion 1u and the concave portion 10a are provided at two locations, but may be provided at only one location. Moreover, although the convex part 1u and the recessed part 10a are provided in rod shape, you may provide in semicircle shape not only this. That is, a semicircular semicircular concave portion and a semicircular convex portion that engages with the semicircular concave portion may be provided. As described above, the main body 1a and the lever 1b have a concave portion on one side and a convex portion that engages with the concave portion on the other side, and the main body 1a and the lever 1b can be latched by the concave portion and the convex portion. The shape of the concave portion and the convex portion is not limited.

  The slopes 1s and 1t are an example of an inclined portion, which is formed in a fan shape and is provided to face the mounting portion 1q. The slope of the slope 1s is formed so that the vicinity of the convex portion 1u is the lowest and the vicinity of the step portion 1y is the highest with respect to the plane of the mounting portion 1q. Similarly, the slope of the slope 1t is formed so that the vicinity of the convex part 1u is the lowest and the vicinity of the step part 1z is the highest. The inclination angles of the slopes 1s and 1t are set to be the same. The step portions 1y and 1z are formed one step higher than the plane of the mounting portion 1q. In this example, the step portions 1y and 1z are formed at the same height as the uppermost portions of the slopes 1s and 1t.

  The protrusion 1b provided on the bottom surface of the head 1c of the lever 1b shown in FIG. Further, the protrusion 1c provided on the bottom surface of the head 1c of the lever 1b shown in FIG. FIG. 3 is a perspective view showing a configuration example of the bottom side of the lever 1b.

  These protrusions 10b and 10c are provided so as to protrude from the bottom surface of the head 1c of the lever 1b. Thereby, according to the rotation of the lever 1b, the protrusions 10b and 10c of the lever 1b are raised or lowered while contacting the slopes of the slopes 1s and 1t, respectively.

  In this example, when the grip portion 1e of the lever 1b is rotated toward the slopes 1s and 1t, the protrusions 10b and 10c of the lever 1b are raised while abutting against the slopes of the slopes 1s and 1t, respectively. Further, when the grip portion 1e of the lever 1b is rotated toward the step portions 1y and 1z, the protrusions 10b and 10c of the lever 1b come into contact with the side surfaces of the step portions 1y and 1z and stop.

  Thus, the leg 1d of the lever 1b moves up and down in accordance with the rotation of the lever 1b. The leg 1d is tightened with the support 2 sandwiched in cooperation with the main body 1a at a fixed position when ascending. Thereby, the holder 1A can fix the support body 2 interposed between the leg 1d of the lever 1 and the main body 1a and can stop the lever 1.

  4A to 4C are perspective views showing an operation example of the holder 1A (1B). The holder 1A shown in FIG. 4A is a fixed position (first position) in which the support 2 is clamped and fixed in cooperation with the main body 1a. In this state, the grip portion 1e of the lever 1b and the corner portion 1n of the leg portion 1d face the slope 1s side (see FIG. 2). The protrusions 10b and 10c of the lever 1b are in contact with the slopes of the slopes 1s and 1t of the main body 1a and climb up the slopes 1s and 1t. Thereby, the leg part 1d of the lever 1b rises. Therefore, the holder 1A can stop and stop the support 2 interposed between the leg 1d of the lever 1b and the main body 1a.

  In this example, since the leg 1d of the lever 1b is raised, the holder 1A is fastened with the rail 2a of the support 2 sandwiched between the upper surface 1v of the main body 1a and the leg 1d of the lever 1b. As a result, the holder 1A can be fixed to the support body 2, and the frictional force between the main body 1a, the rail 2a and the lever 1b acts to stop the lever 1b at the fixed position. The holder 1A is fastened with the rail 2a of the support 2 sandwiched between the side surface 1w of the main body 1a and the leg 1d of the lever 1b. Thereby, 1 A of holders and the support body 2 can be fixed.

  A holder 1A shown in FIG. 4B is a transfer position (second position) for transferring the length measuring device 3 in the direction of sliding with a gap with the support 2. In this state, the grip portion 1e of the lever 1b and the corner portion 1n of the leg portion 1d face the front. Further, the concave portion 10a of the lever 1b is engaged with the convex portion 1u of the main body 1a. Thereby, since a click feeling can be given, a transfer position can be judged clearly and operativity can be improved. The leg 1d of the lever 1b is lowered and positioned at the lowermost part. At this time, the holding tool 1A can loosen the holding tool 1A from the support 2 because the leg 1d does not contact the rail 2a of the support 2.

The holder 1A shown in FIG. 4C is a separation position (third position) in which the width of the leg 1d is narrower than the width of the support 2 and the holders 1A and 1B are removed from the support 2. In this state, the grip portion 1e of the lever 1b and the corner portion 1n of the leg portion 1d face the step portion 1z side. At this time, the width of the leg 1d of the lever 1b is narrower than the distance between the pair of rails 2a of the support 2 shown in FIG.

The protrusions 10b and 10c of the lever 1b come into contact with the stepped portions 1y and 1z of the main body 1a at the deviation position shown in FIG. 4C and stop rotating. At this time, the leg 1d has a width of the leg 1d narrower than the distance between the pair of rails 2a in the support 2, and the leg 1d is automatically detached from the support 2. Thereby, the user can clearly determine the deviation position of the holder 1A.

  When shifting from the fixed position shown in FIG. 4A to the transfer position shown in FIG. 4B, the user rotates the grip portion 1e of the lever 1b by about 30 ° in the left direction. 4B, when the user moves from the transfer position shown in FIG. 4C to the separation position shown in FIG. 4C, the user rotates the grip portion 1e of the lever 1b to the left by about 30 °. 4A, when the user moves from the fixed position shown in FIG. 4A to the separation position shown in FIG. 4C, the user rotates the grip portion 1e of the lever 1b by about 60 ° in the left direction.

  Similarly, when shifting from the deviation position shown in FIG. 4C to the transfer position shown in FIG. 4B, the user rotates the grip portion 1e of the lever 1b by about 30 ° in the right direction. 4B, when the user moves from the transfer position shown in FIG. 4B to the fixed position shown in FIG. 4A, the user rotates the grip portion 1e of the lever 1b to the right by about 30 °. Further, when shifting from the deviation position shown in FIG. 4C to the fixed position shown in FIG. 4A, the user rotates the grip portion 1e of the lever 1b to the right by about 60 °.

  In this way, it is possible to move to each position with a single touch without turning many times like a dial, so that the holders 1A and 1B can be securely attached and detached even in places where work cannot be confirmed with the naked eye when working in a narrow place. Can do. In addition, although the angle at the time of switching to each position was set to about 30 ° as an example, the angle is not limited to this and may be any angle that can be switched with one touch.

Next, a usage example of the holding device 100 will be described. The length measuring device 3 is incorporated as a device as a positioning device when the machine tool is assembled. Generally, the length measuring device 3 is first attached to a machine tool, but the read head of the length measuring device 3 is held at a temporary position (fixed position). Thereafter, the read head is transferred to the position of the bracket (transfer position). The reading head is fixed with a screw at the position of the bracket, and the holders 1A and 1B are removed (dissociation position). These holders 1A and 1B can be removed after the reading head is fixed, and can be repeatedly used for the same work even during maintenance work.

Thereby, the operation of the lever 1b becomes clear. That is, the transfer direction of the lever 1b of the holders 1A and 1B can be clearly determined when working in a narrow place that cannot be confirmed with the naked eye. Further, by rotating right or left with reference to this transfer direction, the fixed position and the deviation position can be set without visual confirmation.

  FIG. 8 is a front view showing a transfer position of the holder 1A (1B). The concave portions 10a and 10a of the lever 1b of the holders 1A and 1B shown in FIG. 8 are engaged with the convex portions 1u and 1u of the main body 1a. At this time, the leg portion 1d of the lever 1b is lowered and the lower portion 1k of the leg portion 1d is positioned at the fitting portion 2b of the rail 2a. Thereby, 1 A of holders can loosen the support body 2 interposed between the leg part 1d of the lever 1, and the main body 1a. Since the length measuring device 3 shown in FIG. 7 is connected to the holders 1A and 1B, the length measuring device 3 can be transported on the rail 2a of the support 2 together with the holders 1A and 1B.

FIG. 9A is a perspective view showing a deviation example of the length measuring device 3 by the holding device 100.
