The mounting end of the motor 22 is installed corresponding to the fixture table 1, and the motor 22 is fixedly connected to the fixture table 1. The output end of the motor 22 is installed corresponding to one end of the guide rail 21, and the output end of the motor 22 is fixedly connected to one end of the lead screw on the guide rail 21. A clamping plate 23 is arranged at the end of the guide rail 21 away from the motor 22. The clamping plate 23 includes an assembly table 231. The mounting end of the assembly table 231 is installed corresponding to the upper part of the fixture table 1. The mounting end of the assembly table 231 is fixedly connected to the tooling table 1. The assembly table 231 contains a rotating plate 232 and a rotating plate 233. The mounting ends of the rotating plates 232 and 233 are respectively installed in the inner cavity of the assembly table 231. Both rotating plates 232 and 233 are rotatably connected to the assembly table 231. The assembly table 231 contains four sets of clamping plates 234. Four sets of mounting slots are provided on the assembly table 231. The clamping plates 234 are installed in corresponding mounting slots and are slidably connected to the inner wall of the mounting slots. The clamping plates 234 are arranged in an arc shape on one side, which allows for better contact with the outer periphery of the screws. A cover plate 27 is provided above the assembly table 231. The mounting end of the cover plate 27 is connected to the upper part of the assembly table 231. The cover plate 27 is fixedly connected to the screw, and can block the rotating plate 233. Guide grooves are provided on the rotating plate 232, rotating plate 233, and cover plate 27. The mounting ends of the clamping plates 234 are respectively installed in relation to the guide grooves, and are slidably connected to them. Multiple sets of clamping plates 234 can clamp the screw, making it more stable during processing. Each set of clamping plates 234 has a pressure sensor 235 located on one side close to each other. An assembly hole is provided on one side of the clamping plate 234, and the mounting end of the pressure sensor 235 is installed in relation to the assembly hole.

One end of the two sets of push rods 26 is respectively installed corresponding to the two ends of the synchronizing rod 25. The push rods 26 are rotatably connected to the synchronizing rod 25. The ends of the two sets of push rods 26 away from the synchronizing rod 25 are respectively installed corresponding to one side of the rotating plate 1 232 and the rotating plate 233.Two sets of push rods 26 are rotatably connected to rotating plate 1 232 and rotating plate 233 respectively. The first clamping assembly 2, through the pushing action of the push rods 26 by the synchronous rod 25, drives rotating plate 1 232 and rotating plate 233 to rotate within the assembly table 231. This allows the clamping plate 234 to slide through the guide hole, thereby enabling multiple sets of clamping plates 234 to clamp and securely hold the lead screw, facilitating stable placement of the lead screw during machining operations.

An assembly groove is opened at the middle position on the placement platform 3. The mounting end of the magnet 4 is installed corresponding to the assembly groove. The magnet 4 is fixedly connected to the placement platform 3. The setting of the magnet 4 can attract the screw, thereby making the screw more stable when placed, which facilitates the clamping operation of the first clamping component 2.

[0022] A second clamping assembly 5 is provided below the tooling table 1. The second clamping assembly 5 includes a guide rod 51 located below the placement table 3. A shaft hole is opened on the tooling table 1 below the placement table 3. One end of the guide rod 51 passes through the shaft hole and is installed correspondingly to one side of the lower part of the placement table 3. One end of the guide rod 51 is fixedly connected to the lower part of the placement table 3. A synchronizing rod sleeve 52 is fitted around the outer ring of the guide rod 51. The inner ring of the synchronizing rod sleeve 52 is installed correspondingly to the outer ring of the guide rod 51. The synchronizing rod sleeve 52 is fixedly connected to the guide rod 51. Y-shaped push rods 53 are provided on both sides of the synchronizing rod sleeve 52. Connecting rods 57 are provided on both sides of the synchronizing rod sleeve 52. One end of the Y-shaped push rod 53 is connected to one end of the connecting rod 57. The connecting rod 57 is rotatably connected to the Y-shaped push rod 53 at one end, and to the synchronizing rod sleeve 52 at the other end. A cylinder 54 is installed between the two sets of Y-shaped push rods 53 at their closest points. A connecting rod 55 is installed on the end of the Y-shaped push rod 53 away from the cylinder 54. The mounting end of the cylinder 54 is correspondingly installed on the end of the Y-shaped push rod 53 away from the connecting rod 55. The mounting end of the cylinder 54 is rotatably connected to one end of one set of Y-shaped push rods 53. The output end of the cylinder 54 is correspondingly installed on one end of the other set of Y-shaped push rods 53. The output end of the cylinder 54 is rotatably connected to the other end of the other set of Y-shaped push rods 53. A clamping block 56 is installed on one end of the connecting rod 55. One side of the clamping block 56 is arc-shaped, which allows for better contact with the screw. One end of the connecting rod 55 is installed corresponding to one side of the clamping block 56 and is rotatably connected to the clamping block 56. The other end of the connecting rod 55 is installed corresponding to one end of the Y-shaped push rod 53 and is rotatably connected to the Y-shaped push rod 53. Mounting brackets 6 are provided on both sides of the tooling table 1. The mounting end of the mounting bracket 6 is installed corresponding to one side of the tooling table 1, and the other end of the mounting bracket 6 is fixedly connected to the outer side of the cover plate 27. A limiting groove 7 is provided on the mounting bracket 6, and the mounting end of the clamping block 56 is installed corresponding to the limiting groove 7, allowing the clamping block 56 to slide within the limiting groove 7. The Y-shaped push rod 53 is connected to the mounting bracket 6 at one end near the connecting rod 55. The Y-shaped push rod 53 is rotatably connected to the mounting bracket 6. The mounting bracket 6 makes the Y-shaped push rod 53 more stable when it is in the assembled state. At the same time, the Y-shaped push rod 53 can be pushed by the cylinder 54 and the connecting rod 55 to push the clamping block 56, so that the clamping block 56 moves along the limiting slide groove 7. The two sets of clamping blocks 56 can clamp the screw. The second clamping component 5 can cooperate with the first clamping component 2 to double clamp and stabilize the screw, which greatly improves the stability of the screw when it is in the processing state and facilitates the operator to quickly process the screw.

[0023] In this embodiment, the operator first places the screws to be processed on the placement table 3, and uses the magnet 4 to attract the screws. Then, the operator powers on the motor 22 and the cylinder 54. The motor 22 drives the slider 24 to move via the guide rail 21. The movement of the slider 24 pushes the push rod 26 via the synchronizing rod 25, thereby causing the push rod 26 to push the rotating plates 232 and 233 to rotate within the assembly table 231. The rotation of the rotating plates 232 and 233 guides the clamping plate 234 within the assembly table 231 via the guide groove. The movement of the clamping plate 234 clamps the screws attracted by the magnet 4. When the clamping plate 234 and the screw are in contact, the pressure sensor 235 detects the clamping pressure. When the pressure reaches the set threshold, the motor 22 stops working, and at the same time, the cylinder 54 pushes the Y-shaped push rod 53. The Y-shaped push rod 53, after being pushed, drives the synchronous rod sleeve 52 to slide along the guide rod 51 through the connecting rod 57. At the same time, the other end of the Y-shaped push rod 53 pushes the clamping block 56 through the connecting rod 55, so that the clamping block 56 slides along the limiting slide groove 7, thereby clamping the upper part of the screw with the two sets of clamping blocks 56, thus completing the screw fastening operation and starting the screw strength test.
