A rotating rod 32 is connected, and the rear end of the rotating rod 32 is rotatably connected to the fixed rod 33. The rear ends of the first rack 30 and the fixed rod 33 are respectively provided with a first slot 28 and a second slot 34. A first plug rod 59 is inserted in the first slot 28, and a second plug rod 35 is inserted in the second slot 34. The first plug rod 59 is fixedly connected to the fixed block 58, and the fixed block 58 is fixedly connected to the support frame 60. The support frame 60 is fixedly connected to the device base 21. The second plug rod 35 is fixedly connected to the front end of the processing table 20. The top end of the fixed rod 33 is fixedly connected to a placement slot 36. The top end of the placement slot 36 is semicircular in design, and the rear end of the placement slot 36 is aligned with the front end of the stamping slot 64.

[0035] Through the structural design of the conveying mechanism, during the riveting process of the wire head and the terminal, the wire harness can be automatically moved and the wire head can be moved to the stamping groove 64, and the wire head can be removed from the stamping groove 64 after the riveting is completed, so as to ensure that the distance of the wire head moving each time can be consistent, reduce the error caused by manual placement of the wire head, and thus ensure the connection quality between the wire head and the terminal. When working, the top of the placement groove 36 is designed to be semicircular for placing the wire harness. When the stamping mechanism 1 moves downward for stamping operation, the stamping mechanism 1 will bring The first connecting rod 22 and the first connecting rod 23 move downward, and the first connecting rod 23 is rotatably connected to the second connecting rod 27, and the second connecting rod 27 is rotatably connected to the connecting block 29. The side of the second connecting rod 27 close to the first connecting rod 23 moves downward, and the front end of the second connecting rod 27 pulls the connecting block 29 to move backward. The connecting block 29 then drives the first rack 30 to move backward, and the first rack 30 is meshed with the part with the tooth groove on the side of the rotating disk 31, so that the rotating disk 31 is driven to rotate, and the rotating disk 31 drives the rotating rod 32 to rotate during the rotation process. The first connecting rod 33 is connected to the second connecting rod 33 by a second connecting rod 35 inserted in the second slot 34, so that the fixing rod 33 can only move in the front-rear direction. Therefore, the rotating rod 32 can stably drive the fixing rod 33 to move backward, and the fixing rod 33 drives the placement slot 36 to move. The wire harness is placed on the placement slot 36, and the wire end at the rear end of the wire harness will complete the stamping operation on the stamping slot 64. Similarly, when the stamping is completed, the stamping mechanism 1 will lift up and drive the connecting rod 22 and the first connecting rod 23 to move upward. At the same time, the rotating disk 31 will rotate in the opposite direction, so that the placement groove 36 gradually moves away from the processing table 20, and finally the wire harness punched on the placement groove 36 can be removed. A first slot 28 is opened inside the first rack 30, and the contact between the inner wall of the first slot 28 and the first plug rod 59 is ensured to ensure that the first rack 30 can move stably and mesh correctly with the rotating disk 31. A trapezoidal groove 45 is opened under the second connecting rod 27 to ensure that the bottom end of the second connecting rod 27 will not abut against the top of the device base 21 when the second connecting rod 27 moves downward.

[0036] Further, the clamping mechanism includes two groups of clamping blocks 46, the clamping blocks 46 are located on the left and right sides of the placement groove 36, the clamping blocks 46 are L-shaped, the bottom ends of the clamping blocks 46 are fixedly connected to the connecting column 42, the bottom ends of the connecting column 42 are rotatably connected to the rotating block 41, the side of the rotating block 41 away from the connecting column 42 is rotatably connected to the bottom end of the rotating plate 39, the bottom end of the rotating plate 39 is rotatably connected to the support rod 40, the bottom end of the support rod 40 is fixedly connected to the device base 21, the top end of the rotating plate 39 is provided with a U-shaped groove 38, the inside of the U-shaped groove 38 is slidably connected with a protrusion 37, the protrusion 37 contacts the inner wall of the U-shaped groove 38, the protrusion 37 is fixedly connected to the bottom end of the fixed rod 33, the rear end of the clamping block 46 is fixedly connected with a card block 43, the card block 43 is slidably connected to the inside of the card slot 44, and the card slot 44 is provided at the front end of the processing table 20;

[0037] Through the structural design of the clamping mechanism, the function of clamping and fixing the left and right sides of the wire harness is realized after the wire end of the wire harness is fed into the stamping groove 64, so that the wire harness will not move when the stamping mechanism 1 rivets the wire end, and the clamping and fixing of the left and right sides of the wire harness are automatically released after the riveting is completed, so that the operator can remove the wire harness. During operation, when the fixing rod 33 drives the placement groove 36 to move backward, the fixing protrusion 37 on the bottom end of the fixing rod 33 will slide in the U-shaped groove 38 and drive the rotation through the contact between the protrusion 37 and the inner wall of the U-shaped groove 38. The plate 39 rotates, and the bottom end of the rotating plate 39 is rotatably connected to two groups of rotating blocks 41. Since the clamping block 43 fixed on the rear end of the clamping block 46 slides in the clamping groove 44, the clamping block 46 can only slide in the left and right directions. Therefore, when the rotating plate 39 drives the rotating block 41 to rotate, the rotating block 41 will drive the two groups of clamping blocks 46 to approach each other until the top part of the clamping block 46 clamps the wiring harness. Similarly, when the fixing rod 33 drives the placement slot 36 to move forward, the rotating plate 39 will rotate in the opposite direction to make the two groups of clamping blocks 46 move away from each other, thereby releasing the clamping fixation of the wiring harness by the top end of the clamping block 46.

[0038] Further, the feeding mechanism includes two groups of discharge plates 57, the discharge plates 57 are fixedly connected to the support frame 60, one side of the two groups of discharge plates 57 is provided with a through slot 62, the second slide plate 63 and the first slide plate 55 are slidably connected inside the two groups of through slots 62, the front ends of the second slide plate 63 and the first slide plate 55 are fixedly connected to the connecting plate 56, the right side of the first slide plate 55 is fixedly connected to the special-shaped rod 54, the bottom end of the special-shaped rod 54 is fixedly connected to the second rack 53, the second rack 53 is meshed with the gear 52, the bottom end of the gear 52 is rotatably connected to the device base 21, the gear 52 is meshed with the fixed disk 50, the side of the fixed disk 50 is provided with a tooth groove, the fixed disk 50 is fixedly connected to the rotating shaft 49, and the second rack 53 is provided with a first slot 28;

[0039] Through the structural design of the feeding mechanism, multiple groups of wire harnesses are placed in two groups of feeding plates 57. When the wire ends of one group of wire harnesses are riveted and removed, a new group of wire harnesses will fall from the feeding plate 57 to the placement groove 36, so as to realize the cyclic feeding of the wire harnesses, thereby improving the processing efficiency. During operation, multiple groups of wire harnesses are placed inside the two groups of feeding plates 57. The wire harnesses at the bottom of the feeding plate 57 will contact the top of the first slide plate 55. The distance between the two groups of feeding plates 57 and the wire harnesses is slightly larger than the diameter of the wire harnesses, so that the wire harnesses can move downward under the action of gravity, and the wire harnesses will also be arranged vertically in a row inside the feeding plate 57. Through grooves 62 are provided on both groups of feeding plates 57, and the positions and heights of the through grooves 62 are different. The through grooves 62 on the left are higher than the through grooves 62 on the right. When the placement groove 36 is located at Figure 1 When the wire harness placed on the placement slot 36 is in the position shown, the wire harness placed on the placement slot 36 has been stamped. The second slide plate 63 is inserted between the two sets of discharge plates 57 to block the wire harness above the second slide plate 63. At this time, the first slide plate 55 will be located on one side of the discharge plate 57, so that the bottom end of the discharge plate 57 is connected to the outside. At this time, the bottom end part of the wire harness located above the first slide plate 55 will contact the wire harness placed on the placement slot 36. When the wire harness after stamping on the placement slot 36 is removed, the new wire harness falls on the placement slot 36 under the action of gravity, so as to facilitate the next stamping operation. When the stamping mechanism 1 moves downward for stamping, as the rotating disk 31 rotates, the fixed disk 50 fixed on the rotating shaft 49 will rotate synchronously. The fixed disk 50 is also provided with a tooth groove on the side and meshes with the gear 52, and drives the gear 52 to rotate, and the gear 52 then drives the second The second rack 53 moves, and the second rack 53 is connected to the special-shaped rod 54. The top of the special-shaped rod 54 is connected to the first slide plate 55, so that the first slide plate 55 can be driven to move. The first slide plate 55 and the second slide plate 63 are connected together by the connecting plate 56. The first slide plate 55 will gradually close the bottom end of the discharge plate 57, and the second slide plate 63 will gradually slide out from the inside of the discharge plate 57. After the first slide plate 55 closes the bottom end of the discharge plate 57, the wiring harness inside the discharge plate 57 will fall onto the first slide plate 55 again under the action of gravity because there is no support from the second slide plate 63. The special-shaped rod 54 is used to ensure that the special-shaped rod 54 will not abut against the clamping block 46 when driving the first slide plate 55 to move. The second rack 53 is provided with a first slot 28 inside like the first rack 30, and provides support for the movement of the second rack 53 by contacting with the first plug rod 59.

[0040] Furthermore, the two sets of discharge plates 57 do not contact each other, and the middle portion of the connecting plate 56 protrudes forward;

[0041] During operation, the two sets of discharge plates 57 do not contact each other, so that the connector part of the wire harness can smoothly leak out from between the two sets of discharge plates 57, and the middle part of the connecting plate 56 protrudes forward so that the connecting plate 56 will not hinder the wire ends at the front end of the wire harness.

[0042] Furthermore, one side of the discharge plate 57 is fixedly connected with a support plate 61, and the top ends of the two groups of support plates 61 are in contact with the bottom ends of the first slide plate 55 and the second slide plate 63 respectively;

[0043] During operation, the support plate 61 is used to support the first slide plate 55 and the second slide plate 63 so that the first slide plate 55 and the second slide plate 63 can remain stable and not easily shake during the sliding process.

[0044] Furthermore, four sets of pulleys 51 are fixedly connected to the bottom end of the fixed plate 50, and the bottom ends of the pulleys 51 are in contact with the top end of the device base 21;

[0045] During operation, four sets of pulleys 51 are fixed to the bottom end of the fixed disk 50, and the pulleys 51 are distributed in a circle on the fixed disk 50, so as to provide support for the bottom end of the fixed disk 50 when the fixed disk 50 rotates, so that the fixed disk 50 can rotate smoothly, thereby ensuring that the rotation of the rotating disk 31 can remain stable.

[0046] Furthermore, a slider 24 is fixedly connected to the left side of the first connecting rod 23, and the slider 24 is slidably connected to the inside of the slide groove 25. The slider 24 and the slide groove 25 are both trapezoidal in design. The slide groove 25 is opened on the inner wall of the column 26. The inner wall of the column 26 contacts the first connecting rod 23, and the bottom end of the column 26 is fixedly connected to the device base 21.

[0047] During operation, the column 26 is used to support and protect the two side edges of the first connecting rod 23 to prevent the first connecting rod 23 from being damaged due to external collision. At the same time, a slider 24 is fixed on one side of the first connecting rod 23. The sliding of the slider 24 in the slide groove 25 can further ensure that the first connecting rod 23 can remain stable without shaking when moving downward.

[0049] See also Figure 5 As shown, in Comparative Example 1 as another embodiment of the present invention, a cushion strip 47 is fixedly connected to one side of the clamp block 46 close to the placement groove 36, and the cushion strip 47 is made of rubber material;

[0050] When working, the pad strip 47 is made of rubber material and is used to buffer the side of the clamp block 46 close to the placement groove 36 and the placement groove 36 to avoid abutment between the clamp block 46 and the placement groove 36. At the same time, the pad strip 47 can also increase the friction between the clamp block 46 and the placement groove 36, so that when the top end of the clamp block 46 clamps the wire harness, it can also clamp the placement groove 36 to ensure that the placement groove 36 does not shake.

[0051] The top of the clamp block 46 is provided with an arc surface, and the top of the clamp block 46 is fixedly connected with a rubber sheet 48;
