Description

Technical Field

[0001] This application relates to the field of stud welding technology, and in particular to a repair tool for a stud welding gun holder. Background Technology

[0002] In stud welding, a stud welding torch holder is used to hold the stud. The structure of the stud welding torch holder is as follows: Figure 1 As shown, the rear end of the clamp is a circular sleeve 1-1, and the front end of the clamp has a segmented structure, consisting of multiple segments 1-2 enclosed together. There is a gap between the rear ends of adjacent segments 1-2, and the front ends of adjacent segments 1-2 are constricted and gradually come into contact. In use, the front end can open to clamp the stud. In actual application, due to frequent opening and closing and uneven force on each segment 1-2, the root of some segments 1-2 is prone to breakage, causing some segments 1-2 to fall off. The clamp after the segments 1-2 fall off cannot continue to be used and must be scrapped. However, the clamp is relatively valuable, resulting in a waste of production costs. Utility Model Content

[0003] The purpose of this application is to provide a repair tool for a stud welding torch holder, which can repair the holder after the petal has fallen off, thereby effectively solving the shortcomings of the prior art.

[0004] Therefore, this application provides a repair tool for a stud welding torch holder, comprising:

[0005] The first frame is provided with a slot for inserting the rear end of the clamp;

[0006] A clamping member is movably connected to the first frame and is used to abut against the front end of the clamp. The clamping member and the first frame are close to each other to clamp the clamp.

[0007] A collar, which can be fitted onto the front end of the clamp, is used to hold the repair flap at the front end of the clamp for repair.

[0008] The first frame is a conductor, and the clamping member is insulated from the first frame.

[0009] In some possible implementations, there are multiple collars, each with a different notch diameter.

[0010] In some possible implementations, a positioning seat is also included, on which the slot is disposed. The positioning seat is detachably disposed on the first frame. There are multiple positioning seats, and the slots on each positioning seat are of different sizes. The positioning seat is a conductor.

[0011] In some possible implementations, the first frame is provided with a circular threaded groove, the inner wall of the threaded groove is provided with threads, the outer periphery of the positioning seat is provided with threads, and the positioning seat can be screwed into the threaded groove.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figure 2 , Figure 3 As shown, this application provides a repair tool for stud welding gun holders, used to repair holders used with stud welding guns. In the stud welding process, the petals at the front end of the stud welding gun holder are prone to breakage and detachment. After the petals fall off, the holder can no longer be used normally and must be scrapped. However, the holder is made of copper alloy, which is relatively expensive, resulting in wasted production costs. The repair tool for stud welding gun holders provided in this application aims to repair holders with detached petals, avoiding the waste of costs caused by scrapping the holders. More specifically, the specific repair method of this application is as follows: For multiple holders of the same model with detached petals, first take one holder with detached petals and remove all the petals on it using pliers or a cutting saw. Then, replace the detached petals on the other holders with detached petals and then weld them. In this way, the damaged holders can be reused, effectively avoiding cost waste.

[0024] The repair tool for the stud welding torch holder includes a first frame 100, a collar 40, and a clamping member 50. A slot 601 is provided on the first frame 100 for inserting the rear end of the holder. The collar 40 is circular in shape with a circular notch in the middle. The front end of the holder after the petals are repaired can be inserted into the notch in the middle of the collar 40, so that the notch is tightened at the front end of the holder, thereby stabilizing all the petals. The clamping member 50 is used to abut against the front end of the holder. The clamping member 50 and the first frame 100 cooperate to clamp and fix the holder. The first frame 100 is a conductor, and insulation is formed between the clamping member 50 and the first frame 100.

[0025] In use, after the petals are filled in, the collar 40 is used to secure the front end of the clamp to stabilize each petal. Then, the rear end of the clamp is inserted into the slot 601 of the first frame 100 for fixation. Then, the abutment 50 is moved so that the abutment 50 and the first frame 100 come closer to each other to clamp the clamp between them, making the clamp more stable. Then, the first frame 100 is connected to the negative terminal of the welding circuit, and the filled petals are welded to the clamp using a welding torch. In this embodiment, the clamp is made of copper alloy, and the first frame 100 can be made of iron or copper alloy, as long as it can conduct current.

[0026] Preferably, there are multiple collars 40, and the diameter of the notch on each collar 40 is different. In this way, the corresponding collar 40 can be selected for various grippers to be repaired, thereby improving the applicability of the repair tool. In this embodiment, since the front and rear dimensions of different models of grippers may be different, a positioning seat 600 can also be provided. The positioning seat 600 is detachably mounted on the first frame 100, and the slot 601 is mounted on the positioning seat 600. Moreover, multiple positioning seats 600 are configured, and the slot 601 on each positioning seat 600 is of different size. The positioning seat 600 is a conductor, and the positioning seat 600 contacts the first frame 100, forming an electrical connection with the first frame 100. The slots 601 of different sizes can meet the installation of different models of grippers.

[0027] In this embodiment, only one positioning seat 600 can be installed on the first frame 100 during use. Multiple positioning seats 600 are configured, each with a different sized slot 601. The slot 601 is a circular groove for inserting the rear end of the gripper. The corresponding positioning seat 600 is selected and installed on the first frame 100 according to the gripper model. Preferably, a circular threaded groove 101 can be provided on the first frame 100, with internal threads on the inner wall of the threaded groove 101. The positioning seat 600 has a columnar structure, with the slot 601 recessed into the end face of one end of the positioning seat 600. External threads are provided on the outer periphery of the positioning seat 600, allowing it to be screwed into the threaded groove 101, with the slot 601 facing outwards for insertion and fixation of the gripper. The positioning seats 600 have the same outer peripheral dimensions, but the slots 601 on each positioning seat 600 have different dimensions to accommodate the insertion of different types of clamps. In this embodiment, holes, grooves, or other structures can be provided on the end face of the slots 601 of the positioning seat 600 to facilitate the screwing of the positioning seat 600. Alternatively, the axial length of the positioning seat 600 is greater than the depth of the threaded groove 101, and the threaded groove 101 is coaxial with the positioning seat 600. A chamfer or other structure is provided on the outer peripheral surface of one end of the threaded groove 101 of the positioning seat 600 to facilitate the screwing of the positioning seat 600. In addition, the positioning seat 600 and the first frame 100 are connected by threads, resulting in tighter contact and more stable conductivity, which can effectively avoid the phenomenon of incomplete connection and make the welding process of the petal more reliable.

[0028] Preferably, the repair tool further includes a workbench 70, which is a horizontally placed plate-like structure forming a tabletop. In one embodiment, the workbench 70 is made of an insulating material, and the first frame 100 is directly mounted on the workbench 70 using screws or other components. In another embodiment, the workbench 70 is made of a metal with higher structural strength, such as iron. A second frame 200 can be set on the workbench 70, and the first frame 100 is mounted on the second frame 200. The first frame 100 and the workbench 70 are insulated from each other. To achieve insulation between the first frame 100 and the workbench 70, the second frame 200 can be made entirely of an insulating material, or the specific material of the second frame 200 can be unrestricted. An insulating pad, such as a rubber pad, can be placed between the second frame 200 and the workbench 70, and the second frame 200 and the workbench 70 are connected by screws made of insulating materials such as plastic.

[0029] In this embodiment, a third frame 300 is also provided on the workbench 70. The third frame 300 and the second frame 200 are spaced apart. The clamping member 50 is movably provided on the third frame 300. Insulation is formed between the third frame 300 and the workbench 70. For the insulation between the third frame 300 and the workbench 70, the third frame 300 can be made entirely of insulating material, or an insulating pad, such as a rubber pad, can be provided between the third frame 300 and the workbench 70. The third frame 300 and the workbench 70 are connected by screws made of plastic or other materials. In this way, insulation is formed between the third frame 300 and the workbench 70, and between the first frame 100 and the workbench 70, to prevent accidents during the welding process. The setting of the workbench 70 makes the repair tool modular, and various tools and clamps can also be placed on the workbench 70, improving the convenience of the repair operation.

[0030] Preferably, for the installation of the clamping member 50, an axially adjustable threaded rod 800 is provided on the third frame 300, and the clamping member 50 is located at one end of the threaded rod 800. In this embodiment, a second frame 200 and a third frame 300 are provided. The second frame 200 is an upright plate structure, and the first frame 100 is a solid structure. The first frame 100 can be installed on one side of the second frame 200 by bolt assembly. The third frame 300 is also an upright plate structure. The threaded rod 800 vertically penetrates the third frame 300 and is axially movable through the third frame 300. One end of the threaded rod 800 extends toward the slot 601 on the first frame 100, and the other end of the threaded rod 800 extends away from the slot 601 on the first frame 100. A nut 801 is provided on each side of the threaded rod 800 on the third frame 300. The clamping member 50 is provided at the end of the threaded rod 800 that extends toward the slot 601. By axially moving the threaded rod 800 and then tightening the two nuts 801 to fix the threaded rod 800, the axial adjustment of the threaded rod 800 can be easily realized, that is, the position adjustment of the clamping member 50 can be realized, so that the clamping member 50 and the first frame 100 cooperate to clamp the clamp firmly.

[0031] In this embodiment, the clamping member 50 is plate-shaped and is vertically connected to the end of the threaded rod 800. The plate-shaped clamping member 50 is easier to abut against the end of the clamp.

[0032] In one embodiment, the repair tool further includes a connecting strip 90, which is disposed on the workbench 70. The connecting strip 90 has multiple terminals and is a conductor. The connecting strip 90 can be connected to the welding negative electrode through the terminals. A wire is provided between the connecting strip 90 and the first frame 100. A terminal can also be provided on the first frame 100 to allow electrical connection between the wire and the terminal on the connecting strip 90. The connecting strip 90 and the workbench 70 are insulated from each other. To achieve insulation between the connecting strip 90 and the workbench 70, an insulating pad, such as a rubber pad, is provided between the connecting strip 90 and the workbench 70. The connecting strip 90 and the workbench 70 can be connected by screws made of insulating materials such as plastic.

[0033] By setting up the connecting row 90, multiple workstations can be formed on the workbench 70. Each workstation is equipped with a set of equipment consisting of a first frame 100, a second frame 200, a third frame 300, a threaded rod 800, a clamping part 50, a positioning seat 600, and a collar 40. Each first frame 100 is connected to different terminals on the connecting row 90, forming multiple welding repair workstations, which helps to improve repair efficiency.
