Description
Technical Field
[0001] This utility model relates to the field of jig technology, and in particular to an industrial robot joint jig. Background Technology
[0002] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machines with a certain degree of automation, widely used in various industrial fields such as electronics, logistics, and chemicals. The robot joint is one of the core components of an industrial robot, consisting mainly of a torque motor, reducer, and encoder, integrated into a cylindrical steel shell. During assembly, the robot joint requires a fixture for positioning.
[0003] Patent announcement number CN221716748U discloses an industrial robot joint fixture, including a bottom main board body. Concave mounting brackets are fixedly connected to the front and rear ends of the top of the bottom main board body. Two sets of clamping component fixing seats are longitudinally arranged between one end of each concave mounting bracket. A clamping component is provided on one side of each clamping component fixing seat for easy replacement. By providing a joint clamping plate, first hand-tightening bolts, and internal threaded grooves, when damage occurs or size adjustment and replacement are required, the two sets of first hand-tightening bolts are loosened and the fixture is pulled out. The first hand-tightening bolts disengage from the internal threaded grooves and lose their restriction on the joint clamping plate. The joint clamping plate can then be lifted out along one side of the clamping component fixing seat for replacement. This achieves the function of easy disassembly and replacement of the clamping components, solving the problem that the device lacks the function of easy disassembly and replacement of the clamping components.
[0004] However, this patent uses a second hand-tightening bolt to adjust and fix the distance between the two clamping fixtures. Tightening the second hand-tightening bolt to adjust the distance between the clamping fixtures takes a long time and cannot achieve rapid adjustment and fixation, which affects the assembly efficiency of the robot joints.

A positioning block 17 is vertically fixed on the bottom surface of the pressure block 3. The top surface of the fixing block 4 is open. Multiple equidistant through holes 18 are provided, which are connected to grooves 8. Positioning blocks 17 are slidably inserted into the through holes 18. A positioning groove 22 is opened on the top surface of the second arc-shaped toothed block 21, and the positioning block 17 is inserted into the positioning groove 22. The bottom surface of the end of the pressure block 3 slides against the L-shaped plate 2. The L-shaped plate 2 is slidably connected to the outside of the fixing block 4.

[0026] The fastener includes a pull rod 31 that slides through the countersunk hole 29. A third spring 30 is sleeved on the outer edge of the pull rod 31. One end of the pull rod 31 is fixedly connected to a pull block 6, and the other end is fixedly connected to an insert block. A slot 27 is opened on the outer side of the clamping block 12, and the insert block is inserted into the slot 27. A slanted groove 28 is opened at the bottom end of the clamping block 12.

The inner side of the support base 10 passes through the countersunk hole 29. The fastener slides through the countersunk hole 29 and snaps into the clamping block 12.
[0027] Working principle: During use, push the L-shaped plate 2 upwards. The L-shaped plate 2 lifts the two pressure blocks 3 upwards, causing the positioning block 17 to disengage from the positioning groove 22 and the through hole 18. At the same time, the fourth spring 35 is compressed, completing the unlocking of the second arc-shaped toothed block 21. Then, place the workpiece to be assembled on the top surface of the base 1, so that the workpiece is located in the arc-shaped opening 13 within the two clamping blocks 12. Under the elasticity of the support base 10 and the first spring 7, when the workpiece enters the arc-shaped opening 13, the support base 10 and the clamping blocks 12 move in opposite directions, causing the first spring 7 to release the pressure block 17. 7. Compression occurs, and simultaneously, under the elasticity of the first spring 7, the two clamping blocks 12 will automatically adjust their spacing according to the outer diameter of the workpiece, while tightly abutting against the outer edge of the workpiece. When the support base 10 moves, the second arc-shaped toothed block 21 on the outer side of the support base 10, under the elasticity of the second spring 24, meshes with the first arc-shaped toothed block 9. After the workpiece is clamped, the L-shaped plate 2 is released, and the fourth spring 35, which is in a compressed state, returns to its original position, causing the pressure block 3 to descend. The pressure block 3 drives the positioning block 17 to descend, allowing the positioning block 17 to pass through the corresponding through hole 18 and insert into the second arc-shaped toothed block 9. The positioning groove 22 on the top surface of the toothed block 21 completes the limiting and fixing of the clamping block 12. When the clamping block 12 needs to be replaced, pull the pull block 6. The pull block 6, through the pull rod 31, retracts the insert block from the slot 27 in the clamping block 12 into the countersunk hole 29 in the support base 10. At the same time, the third spring 30 is compressed, and then the clamping block 12 is pulled upward from the support base 10, so that the T-shaped block 14 on the clamping block 12 separates from the T-shaped groove 11 on the support base 10. Then, release the pull block 6, the third spring 30 returns to its original position, pushes the insert block out of the countersunk hole 29, and then the required installation is completed. The T-shaped block 14 on the clamping block 12 is aligned with the T-shaped groove 11 on the support base 10. Then, the clamping block 12 is pressed down so that the T-shaped block 14 is engaged in the T-shaped groove 11. At the same time, under the guidance of the inclined groove 28, the third spring 30 and the rounded corner 32 on the insert, the insert is squeezed into the countersunk hole 29 when the pressure block 3 descends. At the same time, the third spring 30 is compressed. When the slot 27 is aligned with the insert and the clamping block 12 is installed in place, the compressed third spring 30 returns to its original state, so that the insert is inserted into the slot 27, thus completing the replacement of the clamping block 12.
