The joint clamp which clamps the joint 16 coaxially with the axial center of the tube 12 when the joint 16 assembled | attached to the tube 12 while the tube clamp part 14 and the tube clamp part 14 are assembled | attached to the tube 12 is set. At least one of the portion 20, the tube clamp portion 14, and the joint clamp portion 20, more specifically, the joint clamp portion 20 is relatively moved in the axial direction of the tube 12, and thus the end portion 12 a of the tube 12, more specifically In the assembly, press the joint 16 into the tip 12a1. Keru assembly and means 22.

  As shown in FIG. 3, the tube 12 is formed of a hollow tube having an axial core 12b. In this embodiment, the tube 12 is manufactured from a relatively hard material such as rubber. The joint 16 has an L-shape and is press-fitted into the end 12a of the tube 12, more specifically, the tip 12a1, and a tube 16a having an axis 16a1 and a substantially right angle to the tube 16a via the joint 16b. 16c connected to the pipe. The joint 16 is manufactured from a relatively hard material such as resin.

  The assembling means 22 includes a slide cylinder 22a installed on the platform 10, an air supply source 22b, an air supply circuit 22c for supplying or stopping supply of air sent from the air supply source 22b to the slide cylinder 22a, and an air supply circuit. An ECU (Electronic Control Unit) 22d for controlling the operation of 22c is provided. The ECU 22d includes a microcomputer including a CPU, ROM, RAM, I / O, and the like.

  When the slide cylinder 22a is supplied with air from the air supply source 22b via the air supply circuit 22c, the slide cylinder 22a moves in the direction of the axis 12b of the tube 12 clamped by the tube clamp portion 14 disposed opposite to the slide cylinder 22a. When the supply of air is stopped, it is configured to return to the initial position (position shown in FIGS. 1 and 2) via an appropriate return means (not shown).

  The joint clamp portion 20 is attached to a base 20a installed on the slide cylinder 22a, and is divided into left and right sides in plan view with an extension line of the axis 16a1 of the pipe 16a of the joint 16 to be clamped as a boundary. Displaceable clamp pieces 20b and 20c are provided. A gap 20d is formed between the clamp pieces 20b and 20c.

  When the joint 16 is set in the gap 20d between the clamp pieces 20b and 20c by the operator, the joint clamp portion 20 brings the clamp pieces 20b and 20c closer to each other and more specifically the joint 16 and more specifically the pipe 16a. The shaft core 16a1 is configured to be clamped coaxially with the shaft core 12b when the tube 12 is set later.

  Although illustration is omitted, the joint clamp part 20 is connected to the air supply source 22b via the air supply circuit 22c, and air (clamping force) is supplied from the air supply source 22b via the air supply circuit 22c by the ECU 22d. The clamp pieces 20b and 20c are displaced and the operator presses the joint 16 set in the gap 20d from both sides to clamp (fix) it, and when the supply of air is stopped, an appropriate return means (not shown) The clamp pieces 20b and 20c are attached to the base 20a so as to return to the initial position (position shown in FIG. 2).

  As shown well in FIG. 2, the joint clamp part 20 is formed with a recess 20e having a shape corresponding to the shape of the joint 16 in the clamp pieces 20b and 20c forming the gap 20d on the side facing the tube clamp part 14. When an operator sets the joint 16 in the gap 20d, the shaft core 16a1 of the pipe 16a of the joint 16 is clamped by pressing the clamp pieces 20b and 20c from both sides. And is configured to clamp securely on the same axis.

  The tube clamp part 14 includes a base 14a installed on the platform 10 and a tube receiving part 14b installed on the platform 10 adjacent to the base 14a.

  The tube receiving portion 14b has a fixed width groove 14b1 communicating with the gap 14e of the tube clamp portion 14, so that the operator can set the tube 12 in the gap 14e of the tube clamp portion 14 and the groove 14b1 of the tube receiving portion 14b. Configured.

  The tube clamp portion 14 is configured to include clamp pieces 14c and 14d that are divided on the left and right sides in plan view with the axis 12b of the tube 12 to be clamped as a boundary and can be displaced relative to each other.

  Although illustration is omitted, the tube clamp portion 14 is also connected to the air supply source 22b via the air supply circuit 22c, and air (clamping force) is supplied from the air supply source 22b via the air supply circuit 22c by the ECU 22d. The clamp pieces 14c and 14d are displaced and the operator presses the tube 12 set in the gap 14e from both sides to clamp (fix) it, and when the supply of air is stopped, an appropriate return means (not shown) The clamp pieces 14c and 14d are attached to the base 14a so as to return to the initial position (position shown in FIG. 2).

  Moreover, the tube clamp part 14 is provided with the tube end holding | maintenance part 24 which can be operated so that the edge part 12a of the tube 12 may be hold | maintained or open | released.

  The tube end holding portion 24 is attached to a base 14 a installed on the platform 10 adjacent to the tube clamp portion 14, and similarly to the tube clamp portion 14, the tube end holding portion 24 is planar on the axis 12 b of the tube 12 to be held. When the tube 12 is set in a gap 24c formed between the holding pieces 24a and 24b by the operator, the holding pieces 24a and 24b are divided into the left and right sides when viewed, and are mutually displaceable. Are arranged so as to be close to each other to hold the tube 12, more specifically, its end 12a.

  The gap 24c of the tube end holding portion 24 communicates with the gap 14e of the tube clamp portion 14 and the groove 14b1 of the tube receiving portion 14b. When the operator sets the tube 12 in the tube clamp portion 14, the tube 12 is connected to the gap 24c and the tube. It is comprised so that it may accommodate in the space | gap 14e of the clamp part 14, and the groove | channel 14b1 of the tube receiving part 14b.

  Although not shown, the tube end holding part 24 is also connected to the air supply source 22b via the air supply circuit 22c, and when the air is supplied from the air supply source 22b via the air supply circuit 22c by the ECU 22d, the holding piece 24a and 24b are displaced and the end 12a of the tube 12 set in the gap 24c is clamped by pressing from both sides by an operator, and when the air supply is stopped, an appropriate return means (not shown) The clamp pieces 20b and 20c are attached to the base 14a so as to return to the initial position (position shown in FIG. 2).

  The closed width of the gap 24c of the tube end holding portion 24 (the separation distance between the holding pieces 24a and 24b when guiding the tube 12) is to make the tube end holding portion 24 function as a guide for the tube 12 during press-fitting. The outer diameter of the tube 12 is slightly larger.

  On the other hand, the closing width of the gap 14e of the tube clamp portion 14 (the distance between the clamp pieces 14c and 14d when the tube 12 is pressed from both sides and clamped) guides the tube 12 when the tube clamp portion 14 is press-fitted. In order to function as a means for fixing and guiding by clamping, the outer diameter of the tube 12 is made slightly smaller.

  Returning to the description of FIG. 1, a light sensor (detection means) 30 including a light emitting element and a light receiving element is disposed in the groove 14 b 1 of the tube receiving portion 14 b of the tube clamp portion 14 and the gap 20 d of the joint clamp portion 20. .

  When the light projected from the light emitting element toward the light receiving element is blocked by the tube 12 or the joint 16 set by the operator, the optical sensor 30 detects that the ON signal (the tube 12 or the joint 16 is set). In the other cases, an OFF signal is output.

  The output (signal) of the optical sensor 30 is sent to the ECU 22d. Based on the output of the optical sensor 30, the ECU 22d controls the operation of the air supply circuit 22c as described above to control the operations of the tube clamp portion 14, the joint clamp portion 20, the tube end holding portion 24, and the slide cylinder 22a.

  Next, the operation of the jig 1 according to this embodiment shown in FIG. 1 and the like will be described with reference to the flowchart of FIG. This operation is specifically an operation (processing) performed by the ECU 22d.

  The program shown in the figure is started when a main switch (not shown in FIG. 1) is turned on by an operator and operation power is supplied to the ECU 22d.

  In the following, based on the output of the optical sensor 30 in S10, it is determined whether or not the joint 16 has been set (inserted) in the joint clamp portion 20 by the operator.

  When the result in S10 is negative, the above determination is repeated. When the result is affirmative, the process proceeds to S12, and a predetermined time (for example, 1.0 sec) has elapsed, that is, the joint 16 has been set in the joint clamp portion 20. It is determined whether or not a predetermined time has passed since the detection.

  When the result in S12 is negative, the above determination is repeated. When the result is positive, the process proceeds to S14, and the joint clamp unit 20 is operated. That is, when a predetermined time elapses after the optical sensor 30 detects that the joint 16 is set in the joint clamp portion 20, the set joint 16 is clamped by applying air.

  FIG. 5 is a plan view showing the state of the jig 1 during the processing of S10, and FIG. 6 is the processing of S12 to S14.

  As described above, the joint clamp portion 20 is formed with the recesses 20e having a shape corresponding to the shape of the joint 16 in the clamp pieces 20b and 20c that form the gap 20d on the side facing the tube clamp portion 14. The work when setting the joint 16 in the gap 20d (recess 20e) is facilitated, and the joint 16 can be reliably clamped at the intended position.

  Returning to the description of the flowchart of FIG. 4, the process then proceeds to S <b> 16, and it is determined based on the output of the optical sensor 30 whether or not the tube 12 is set on the tube clamp unit 14 by the operator. FIG. 7 is a plan view showing the state of the jig 1 during the process of S16 (and S18 described later).

  As shown in FIG. 7, when the operator sets the tube 12 in the tube clamp portion 14, the end 12a of the tube 12, more specifically, the tip 12a1 of the tube 12 contacts the joint 16 set in the joint clamp portion 20. The operation is instructed so that the tube 12 is set in contact with each other, and the subsequent press-fitting into the tube 12 is easy and reliable.

  When the result in S16 is negative, the above determination is repeated. When the result is positive, the process proceeds to S18, and the tube end holding part 24 is operated to the holding side. That is, when the tube 12 is set on the tube clamp 14 so that the end 12a of the tube 12 contacts the joint 16 set on the joint clamp 20 (by an operator), air (clamping force) is supplied to the tube 12. The end portion 12a is held.

  In the flow chart of FIG. 4, the process then proceeds to S20, where the supply of air is stopped and the tube end holding portion 24 is operated to the open side, and the air is supplied and the tube clamp portion 14 is operated, while the slide cylinder Air is supplied to 22a to move the joint clamp portion 20 toward the tube clamp portion 14, and the tube 16a of the joint 16 is press-fitted into the end portion 12a of the tube 12, more specifically, the tip end 12a1 thereof.

  FIG. 8 is a plan view showing the state of the jig 1 during the process of S20.

  Next, in S22, based on the output of the optical sensor 30, whether or not the tube / joint assembly manufactured by press-fitting the joint 16 into the tube 12 is taken out from the tube clamp part 14 and the joint clamp part 20 by the operator. Judge.

  When the result in S22 is negative, the above determination is repeated, whereas when the result is positive, the program is terminated.

  As described above, in this embodiment, the tube clamp portion 14 that clamps the tube 12 set by an operator, and the joint that is disposed to face the tube clamp portion 14 and is assembled to the tube 12. When the joint 16 is set, at least one of the joint clamp part 20 that clamps the joint 16 coaxially with the axis 12b of the tube 12, the tube clamp part 14 and the joint clamp part 20, specifically, a joint. The clamp part 20 is relatively moved in the axial direction of the tube 12 (the direction of the axial core 12b), so that the joint 16 is press-fitted and assembled to the end 12a of the tube 12, more specifically, the distal end 12a1 thereof. Means (slide cylinder 22a, air supply source 22 In the tube joint assembling jig 1 having an air supply circuit 22c and an ECU 22d), the tube clamp portion 14 is operable to hold or release the end portion 12a of the tube 12. When the tube 12 is set on the tube clamp portion 14 (by an operator), the assembly means holds the end portion 12a of the set tube 12, while the end portion 12a holds the end portion 12a. When the joint 16 is press-fitted, the operation of the tube end holding portion 24 is controlled so as to open the end portion 12a (S10 to S20).

  Thereby, the end 12a into which the tube 12 is press-fitted can be reliably held until immediately before the press-fitting, and even if the tube 12 is manufactured from a relatively hard material, Clamping can be performed without causing misalignment. Therefore, the joint 16 can be easily assembled and work efficiency can be improved.

  In addition, the tube clamp portion is provided with an assembly means 22 such as a slide cylinder 22a in which at least one of the tube clamp portion 14 and the joint clamp portion 20 is relatively moved and the joint 16 is press-fitted into the end portion 12a of the tube 12 to be assembled. 14. A tube end holding portion 24 that does not require an operator's manual operation to move the joint clamp portion 20 or the like and that can be operated to hold or release the end portion 12a into which the joint 16 of the tube 12 is press-fitted. By providing, even an operator who has trouble using both hands can easily work with one hand.

  The tube end holding portion 24 holds the end portion 12a of the tube 12 when a clamping force (air) is supplied, while the tube end holding portion 24 stops the supply of the clamping force when the supply of the clamping force is stopped. The assembling means is operable to open the end portion 12a, and the assembly means supplies the clamping force when the tube 12 is set to the tube clamp portion 14, so that the end of the set tube 12 is set. While holding the portion 12a, when the joint 16 is press-fitted into the end portion 12a, the operation of the tube end holding portion 24 is controlled so as to stop the supply of the clamping force and open the end portion 12a. Since it is configured, the end 12a into which the tube 12 is press-fitted can be held more securely until just before press-fitting, and the tube 12 is made of a relatively hard material. Even if it is, it can be clamped without causing a positional displacement in the tube 12, thus it is possible to improve work efficiency.

  The assembling means is configured to apply the clamping force (air) when the tube 12 is set to the tube clamp 14 so that the end 12a of the tube 12 contacts the joint 16 set to the joint clamp 20. While supplying and holding the end portion 12a, when the joint 16 is press-fitted into the end portion 12a, the supply of the clamping force is stopped and the end portion 12a is opened so that the end portion 12a is opened. Since the configuration is such that the operation is controlled, even when the tube 12 is manufactured from a relatively hard material, the tube 12 can be clamped without causing a positional shift, and work efficiency can be improved. .

  Further, since the joint clamp portion 20 is configured such that a concave portion having a shape corresponding to the shape of the joint 16 is formed on the side facing the tube clamp portion 14, in addition to the above-described effects, the operator can In addition to facilitating the work when setting the 16 in the gap 20d, the shaft core 16a1 of the tube 16a of the joint 16 is coaxial with the shaft core 12b of the tube 12 when clamped by clamping with the clamp pieces 20b and 20c from both sides. It can be clamped securely.

  In addition, the tube clamp part 14 and the joint clamp part 20 can clamp the set tube 12 and the joint 16 when a clamping force is applied, and the assembling means includes the tube clamp part 14. And a detecting means (optical sensor) 30 for detecting that the tube 12 and the joint 16 are set in the joint clamp part 20, and the tube 12 is connected to the tube clamp part 14 and the joint clamp part 20 by the detecting means. When it is detected that the joint 16 is set, the clamp force is applied to clamp the set tube 12 and the joint 16 (S10 to S20). Accurate joint 16 to tube 12 And it can be reliably press-fitted, thus it is possible to improve work efficiency.

  The assembly means applies the clamping force when a predetermined time elapses after the detection means (light sensor) 30 detects that the joint 16 has been set in the joint clamp portion 20. Since the set joint 16 is clamped (S10 to S12), in addition to the above-described effects, the joint 16 can be press-fitted into the tube 12 more accurately and reliably, thereby improving work efficiency. it can.

  In the above description, air is used as a drive source for the slide cylinder 22a or the tube clamp portion 14, but the present invention is not limited to this. For example, electricity or hydraulic pressure may be used.

  Moreover, although the joint clamp part 20 was moved among the tube clamp part 14 and the joint clamp part 20, you may make it move the tube clamp part 14. FIG.
