[0002] The structure of handcuffs usually includes a lock ring, a chain, a swivel, etc. During the production process, the interfaces of the chain links need to be welded. Spot welding or precision welding processes are usually used to ensure that the connection points are firm. The commonly used police handcuff chain consists of two chain links. The traditional chain link structure welding mainly relies on manual welding operations. After welding one, it is necessary to wait until one of the chain links is cooled before welding the second chain link. The welding efficiency is low, and welding needs to rely on manual experience, which easily leads to unstable welding quality. At the same time, during the processing of the chain, it is difficult to ensure that the interface spacing of the chain links meets the welding requirements. Too large an interface spacing will affect the chain link welding strength, and the weld position is too obvious, and the welding quality is uneven.

[0021] When in use, first sleeve the two chain links on the vertical positioning component 4 and the horizontal positioning component 5 respectively. There will be one horizontal and one vertical when the two chain links are connected. The vertical one is sleeved on the vertical positioning component 4, and the horizontal one is sleeved on the horizontal positioning component 5. When the chain links are sleeved, the inclined surface of the block 43 is used to push the block 43 to slide into the sliding hole. When the chain link passes through the block 43, the retaining spring 44 pushes the two groups of blocks 43 to extend. The block 43 clamps the chain link through the positioning protrusion. The chain link cannot swing, but can move laterally. It should be noted that the interface of the vertical chain link is facing upward, but the interface of the horizontal chain link may face left or right. Rotate the mounting ring 7 according to the direction of the horizontal chain link interface so that the spot welding gun 8 is on the same side, and then use the swivel clamping mold assembly 3 to clamp and fix the swivels at both ends of the chain to complete the feeding clamping.

[0028] The spot welding gun 8 welds the interface of the horizontal chain link. After the welding is completed, the lead screw linear slide module 11 drives the clamping table 2 to move, the clamping table 2 drives the chain to move, and the interface of the vertical chain link moves to the bottom of the swivel. At the same time, the lead screw on the lead screw linear slide module 11 drives the transmission pulley 14 to rotate through the driving pulley 12, the transmission pulley 14 drives the transmission shaft 13 to rotate, the transmission shaft 13 drives the driving gear 15 to rotate, the driving gear 15 drives the two sets of transmission gears 113 to rotate synchronously in the opposite direction, and the two sets of transmission gears 113 drive the two sets of balance wheels 110 through the driving pulley 112 and the driven pulley 111. Synchronous reverse rotation, when the spot welding gun 8 is located on the left side, the swing shaft 17 drives the swing frame 19 to rotate, and the swing frame 19 drives the left side balance wheel 110 to engage with the mounting ring 7, so that the balance wheel 110 drives the spot welding gun 8 to rotate from the left side to the vertical state through the mounting ring 7. Similarly, when the spot welding gun 8 is located on the right side, the balance wheel 110 drives the spot welding gun 8 to rotate from the right side to the vertical state through the mounting ring 7, and welds the vertical chain link interface to complete the automatic chain welding. Through the arrangement of this embodiment, the spot welding gun 8 can rotate a fixed angle when the clamping table 2 moves a fixed distance, and the control is simple and the structure is compact.

[0029] Embodiment 5, based on the above embodiment, further includes: a swing gear 18 is fixedly installed on the outer side of the swing shaft 17, two sets of support rods 116 are slidably connected to the top of the processing table 1, and a gear rod 114 is fixedly installed on the bottom of the support rod 116, and the two sets of gear rods 114 are meshed on both sides of the swing gear 18.

[0030] Furthermore, a top spring 115 is provided between the gear rod 114 and the processing table 1, and two sets of locking frames 16 are fixedly installed on the top of the processing table 1. The locking frames 16 and the support rods 116 are arranged correspondingly. A locking pin 161 is inserted into the interior of the locking frame 16, and a tension spring 162 is provided between the locking pin 161 and the locking frame 16. A pin hole 117 is opened on one side of the support rod 116 close to the locking frame 16, and the cross-section of the pin hole 117 is triangular.

[0031] When the spot welding gun 8 is located on the left side, the spot welding gun 8 pushes the left support rod 116 to descend under the action of gravity, and the left support rod 116 drives the left gear rod 114 to descend, and the left gear rod 114 drives the swing shaft 17 to rotate through the swing gear 18, and the swing shaft 17 drives the swing frame 19 to rotate, and the swing frame 19 drives the left swing wheel 110 to engage with the mounting ring 7.

When the mounting ring 7 drives the spot welding gun 8 away from the support rod 116, the position of the swing frame 19 remains unchanged. Therefore, by adjusting the initial position of the spot welding gun 8 first, the rotation direction of the mounting ring 7 can be synchronously adjusted without adding additional drive and electronic control, and the control is simple.
