The main function of a welding jumper is to solve the problem of unconnected or ungrounded key signal lines caused by negligence or other reasons when designing a complex PCB board. In addition, welding jumpers are also used in circuit improvement or repair, or to repair damaged circuit connections;

[0003] Therefore, in order to position its processing location, a welding jig is used. A welding jig is a welding fixture designed and manufactured according to the dimensional coordinate points of the outer shape of the welded parts calibrated during the design of the welding product. Its main purpose is to clamp and position the product. Sometimes, the sizes and shapes of the products to be processed are different. Therefore, if the clamping head is difficult to adjust and replace, it is not easy to clamp a variety of different products. Content of the Utility Model

[0004] The purpose of the utility model is to provide a welding jig for positioning welding jumpers, so as to solve the problem that sometimes the sizes and shapes of the products to be processed are different, and if the clamping head is difficult to adjust and replace, it is not easy to clamp a variety of different products as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A welding jig for positioning welding jumpers, including a top plate, a first working box, a workbench, and a second working box. A first threaded rod is installed inside the second working box. One side of the first threaded rod is connected to a first servo motor. The outer side wall of the first threaded rod is connected to a first threaded block. The top of the first threaded block is connected to a connecting rod by a guiding column. A slot is opened inside the top of the connecting rod. A second adsorption block is fixed at the bottom end inside the slot. A positioning column is inserted into the slot. A first adsorption block is fixed at the bottom end of the positioning column. A bottom plate is fixed at the top end of the positioning column. A clamping block is fixed at one side of the top end of the bottom plate.

[0006] Preferably, a guiding groove is opened inside the top end of the second working box. The size of the guiding groove is larger than that of the guiding column. The first threaded blocks are symmetrically distributed about the central axis of the first threaded rod.

[0007] Preferably, an external thread is fixed on the outer side wall of the first threaded rod. The external threads are mirror-symmetrically distributed about the central axis of the first threaded rod. A threaded connection is formed between the first threaded block and the first threaded rod.

[0008] Preferably, a magnetic adsorption is formed between the second adsorption block and the first adsorption block, and a reserved groove is formed at the middle position inside the workbench.

[0009] Preferably, the first working boxes are symmetrically distributed about the central axis of the workbench. A second threaded rod is installed inside one of the first working boxes. A second threaded block is connected to the outer side wall of the second threaded rod. The back end of the second threaded rod is connected to a second servo motor. A guide rod is installed inside the other first working box. A guide sleeve is connected to the outer side wall of the guide rod.

[0010] Preferably, a threaded connection is formed between the second threaded rod and the second threaded block, and the output end of the second servo motor is connected to the second threaded rod.

[0011] Preferably, vertical rods are connected to the tops of both the guide sleeve and the second threaded block. The tops of the vertical rods are connected to the bottom end of the top plate. An expansion rod is installed at the bottom end of the top plate.

[0012] Preferably, a connecting plate is installed at the bottom end of the expansion rod. An upper pressing block is fixed to the bottom end of the connecting plate. An insulating coating is applied to the outer side wall of the upper pressing block. A position sensor is installed at the middle position of the bottom of the upper pressing block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: This kind of welding jig for butt welding jumper positioning not only improves the adjustment and replacement ability of the clamping head, but also improves the upper positioning ability and protection ability of the welding jig at the same time;

[0014] (1) By opening the reserved groove inside the workbench, which is used for the through movement of the connecting rod. After the first servo motor works, it can drive the first threaded rod to rotate. At this time, the first threaded block on the outside of the first threaded rod moves horizontally in cooperation with it. And based on the external thread distribution of the first threaded rod, the two first threaded blocks can approach or move away from each other. Therefore, when the product is placed at the middle position near the top of the workbench, the two first threaded blocks can be made to approach to clamp the side of the product by using the clamping blocks. The bottom of the clamping block is fixed with a bottom plate, and the size of the bottom plate is larger than that of the reserved groove. And a positioning column is fixed to the bottom of the bottom plate. Therefore, during assembly, the positioning column can be assembled into the slot of the connecting rod, and adsorption positioning is formed by the cooperation of the first adsorption block and the second adsorption block. When it is necessary to replace the clamping block, it can be pulled out upwards to make the positioning column leave the slot, so as to better improve the overall adjustment and replacement ability during the working process;

[0015] (2) By installing the first working box on both sides of the top of the workbench, after the product placement is completed, the second servo motor can be started to drive the second threaded rod to rotate. At this time, the cooperation between the second threaded rod and the second threaded block forms a forward and backward movement. After the vertical rod is connected to the guide sleeve and the second threaded block, the purpose of the top plate moving forward and backward can be achieved. And during the movement, the cooperation between the guide sleeve and the guide rod forms a guiding operation. When moving, the position sensor detects the bottom position. After detecting the product, the telescopic rod can be selected to work to push the connecting plate downward, and finally the upper pressing block completes the upper pressing work, thereby better improving the overall upper positioning ability during the working process;

[0016] (3) By installing the position sensor in the middle of the bottom of the upper pressing block, this position sensor can detect its position. At the same time, an insulating coating is applied to the outer side wall of the upper pressing block. Therefore, when it comes into contact with the product for upper pressing work, it has a certain insulating protection ability, thus better improving the overall protection ability during the working process.
