[0007] The clamping assembly includes a rotating shaft, a gear, and two fixed clamps. The fixed base has a cavity inside, the rotating shaft is rotatably connected to the inside of the cavity, the gear is fixedly sleeved on the outside of the rotating shaft, and slide rails are fixedly connected to the top of the cavity on both sides of the gear. A rack is slidably connected to the outside of each of the two slide rails. Slide grooves are formed on the upper part of both sides of the cavity on opposite sides of the two racks. Slide seats are slidably connected to the outside of the top two ends of the slide grooves. The two fixed clamps are respectively installed on opposite sides of the two slide seats.
[0008] Preferably, the two racks are meshed and connected to the outside of the gear, and the opposite ends of the two slides are fixedly connected to the outside of the two racks.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:
[0015] 1. This utility model uses a forward-rotating handle to drive a worm gear to rotate within the cavity of a fixed base.

[0027] Example
[0028] Please see Figure 1-5 This utility model provides a technical solution: a jig for processing friction plates, including a fixed base 1, a clamping component for fixing friction plates is installed on the fixed base 1, and a driving component is provided inside the fixed base 1.
[0029] By setting up a clamping assembly, friction plates of different sizes can be clamped and fixed, improving the practicality of the clamp. The clamping assembly includes a rotating shaft 3, a gear 4, and two fixed clamps 11. The fixed base 1 has a cavity 2 inside, the rotating shaft 3 is rotatably connected to the inside of the cavity 2, the gear 4 is fixedly sleeved on the outside of the rotating shaft 3, and the top of the cavity 2 is fixedly connected to slide rails 5 on both sides of the gear 4. The outer sides of both slide rails 5 are slidably connected to racks 6. The upper part of both sides of the cavity 2, on the opposite side of the two racks 6, has a sliding groove 7. The inside of the groove 7 is located at the top of the fixed base 1, and the outer sides of both ends of the groove are slidably connected to the slide blocks 8. The two fixed clamps 11 are respectively installed on the opposite sides of the two slide blocks 8. The two racks 6 are respectively meshed and connected to the outer sides of the gear 4. The opposite ends of the two slide blocks 8 are respectively fixedly connected to the outer sides of the two racks 6. The rotating shaft 3 drives the gear 4 to rotate inside the cavity 2. The gear 4 can simultaneously drive the two racks 6 to move on the outer side of the slide rail 5, thereby causing the two fixed clamps 11 to abut against the outer side of the friction plate and limit the position of the friction plate.
[0030] To meet the clamping requirements of different types of friction plates, each of the two slide blocks 8 has a mounting groove 9 on one side. A mounting base 10 is installed inside the mounting groove 9, and a fixing clamp 11 is installed at one end of the mounting base 10. The top of each of the two slide blocks 8 is connected to a fixing bolt 12 by a thread. One end of the fixing bolt 12 is inserted into the mounting groove 9 and connected to the mounting base 10. By rotating the fixing bolt 12 in the reverse direction, one end of the fixing bolt 12 is disengaged from the mounting base 10. At this time, the fixing clamp 11 can be pulled to drive the mounting base 10 out of the mounting groove 9, so that the fixing clamp 11 can be replaced to meet the clamping requirements of different types of friction plates. Insert the mounting base 10 of the new fixing clamp 11 into the mounting groove 9, and then rotate the fixing bolt 12 in the forward direction so that one end of the fixing bolt 12 abuts against the mounting base 10, thus completing the installation of the new fixing clamp 11.
[0031] To ensure the friction plate is securely fixed, the drive assembly includes a worm gear 13, a worm 14, and a handle 15. The worm gear 13 is fixedly sleeved on the outside of the rotating shaft 3 and located at the end away from the gear 4. The worm 14 is rotatably connected to the inside of the cavity 2. The handle 15 is fixedly connected to the end of the worm 14 that extends to the outside of the fixed seat 1. The worm 14 is meshed with the outside of the worm gear 13. By rotating the handle 15 forward, the handle 15 drives the worm 14 to rotate in the cavity 2 of the fixed seat 1. The worm 14 then drives the rotating shaft 3 to rotate through the worm gear 13. The rotating shaft 3 drives the gear 4 to rotate inside the cavity 2, thus completing the drive of the gear 4. The fixed clamp 11 can be moved through the gear 4 and the rack 6. Furthermore, the arrangement of the worm gear 13 and the worm 14 gives the clamp a self-locking effect, making the friction plate more securely fixed.
[0032] To prevent the friction plate from loosening, a limit bolt 16 is threadedly connected to one side of the handle 15. One end of the limit bolt 16 abuts against the outside of the fixed seat 1. After the friction plate is clamped, the limit bolt 16 is rotated in the forward direction so that one end of the limit bolt 16 abuts against the outside of the fixed seat 1, thus preventing the handle 15 from rotating under external force.
[0033] The working principle or structural principle is as follows: When the friction plate needs to be processed, the friction plate is placed on top of the fixed seat 1, and the limiting bolt 16 is rotated in the reverse direction, causing one end of the limiting bolt 16 to disengage from the outside of the fixed seat 1. Then, by rotating the handle 15 in the forward direction, the handle 15 drives the worm gear 14 to rotate in the cavity 2 of the fixed seat 1. The worm gear 14 then drives the rotating shaft 3 to rotate through the worm wheel 13. The rotating shaft 3 drives the gear 4 to rotate inside the cavity 2. Through the gear 4, two racks 6 can be driven to move on the outside of the slide rail 5, thereby driving the two fixed... The fixed clamp 11 abuts against the outer side of the friction plate to limit the position of the friction plate. The operation is simple and quick, and it can clamp and fix friction plates of different sizes, which improves the practicality and convenience of the clamp. The worm gear 13 and worm 14 make the clamp have a self-locking effect, which can ensure that the friction plate is firmly fixed. After clamping, by rotating the limiting bolt 16 in the forward direction, one end of the limiting bolt 16 abuts against the outer side of the fixed seat 1, which can prevent the handle 15 from being rotated by external force and prevent the friction plate from being loosened.
[0034] When different types of friction plates need to be processed, the fixing bolt 12 is rotated in the reverse direction to disengage one end of the fixing bolt 12 from the mounting base 10. At this time, the fixing clamp 11 can be pulled to drive the mounting base 10 out of the mounting groove 9, so that the fixing clamp 11 can be replaced to meet the clamping requirements of different types of friction plates. The mounting base 10 of the new fixing clamp 11 is inserted into the mounting groove 9, and then the fixing bolt 12 is rotated in the forward direction to make one end of the fixing bolt 12 abut against the mounting base 10, thus completing the installation of the new fixing clamp 11. The operation is simple and quick.
