Description

Technical Field

[0001] This utility model relates to the field of spot welding pliers technology, specifically a heavy-duty rotating shaft structure for resistance aluminum spot welding pliers. Background Technology

[0002] Spot welding clamps typically consist of an electrode arm, an electrode head, a drive unit, and a control system. Under appropriate pressure, the molten metal cools and forms a weld spot, thus achieving a strong connection between the metals. The heavy-duty rotating shaft structure can withstand the large pressure and torque generated by the welding clamp during the welding process, ensuring that the welding clamp can stably clamp the electrode and conduct current.

[0003] While existing spot welding clamps can weld metal parts, they are not convenient for securing heavy-duty rotating shafts, which can lead to the shafts falling off during use. They are also inconvenient for installing the welding clamps, requiring a significant amount of time and reducing the efficiency of the equipment. Therefore, a heavy-duty rotating shaft structure for resistance aluminum spot welding clamps has been developed. Utility Model Content

[0006] As a preferred technical solution of this utility model: the outer wall of the heavy-duty rotating shaft body is provided with a locking groove and a limiting groove, and the inner wall of the placement groove is fixedly fitted with a sealing shell.

[0007] As a preferred technical solution of this utility model: the fixing component includes a spring, a connecting plate is fixedly mounted on the outer wall of the spring, a fixing block is fixedly mounted on the end of the connecting plate away from the spring, one end of a steel rope is fixedly mounted on the inner wall of the fixing block, a clamping block is fixedly mounted on the other end of the steel rope, a support rod is provided on the outer wall of the clamping block, a rotating rod is rotatably connected to the inner wall of the support rod, and a pressure block is fixedly mounted on the end of the connecting plate near the fixing block.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This heavy-duty rotating shaft structure for resistance aluminum spot welding clamps involves the worker placing an installation block on the inner wall of the mounting shell to fix the welding clamp body. The worker then rotates the rotating block, causing a bidirectional screw to rotate. This rotation of the bidirectional screw causes two sets of locking blocks to move relative to each other. A limiting rod limits the locking blocks, preventing them from rotating during movement. The locking blocks then move towards the inner wall of the fixing groove, securing the installation block. Next, a toothed block is placed on the inner wall of the toothed groove, limiting the connection between the rotating block and the bidirectional screw. Finally, a bolt is threaded into the inner wall of the threaded groove, fixing the fixing plate and thus completing the installation of the welding clamp body.

[0013] 2. The heavy-duty rotating shaft structure for resistance aluminum spot welding clamps works by having workers place the heavy-duty rotating shaft body on the inner wall of the placement groove when fixing it. This allows the heavy-duty rotating shaft body to apply pressure to the pressure block. Under pressure, the pressure block moves the connecting plate along the inner wall of the placement groove. Simultaneously, the moving connecting plate applies pressure to the spring, which in turn moves the fixing block. This movement of the fixing block pulls the steel cable, applying pressure to the clamping block. Under pressure, the clamping block rotates the rotating rod along the inner wall of the support rod, causing the clamping block to rotate towards the inner wall of the positioning groove, thus clamping and fixing the heavy-duty rotating shaft body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 6 A heavy-duty rotating shaft structure for resistance aluminum spot welding clamps includes a mounting frame 1. A welding clamp body 2 is fixedly mounted on the inner wall of the mounting frame 1. A placement groove 8 is formed on the outer wall of the welding clamp body 2. A fixing component 9 is provided on the inner wall of the placement groove 8. A heavy-duty rotating shaft body 3 is placed on the inner wall of the placement groove 8. A welding rod 6 is fixedly mounted on the inner wall of the mounting frame 1. A welding head 4 is fixedly mounted on the end of the heavy-duty rotating shaft body 3 away from the fixing component 9. A mounting shell 5 is fixedly mounted on the outer wall of the mounting frame 1. A bidirectional screw 14 is rotatably connected to the inner wall of the mounting shell 5. A rotating block 15 is rotatably connected to the outer wall of the screw 14. A locking block 17 is threadedly connected to the outer wall of the rotating block 15. A limit rod 16 is fixedly assembled on the inner wall of the mounting shell 5. An mounting block 7 is placed on the inner wall of the mounting shell 5. A fixing groove 13 is opened on the outer wall of the mounting block 7. A toothed groove 19 is opened on the outer wall of the rotating block 15. A toothed block 20 is placed on the inner wall of the toothed groove 19. A fixing plate 18 is fixedly assembled on the outer wall of the toothed block 20. A threaded groove 22 is opened on the outer wall of the fixing plate 18. A bolt 21 is threadedly connected to the inner wall of the threaded groove 22.

[0024] In the above structure, during the fixing process of the welding clamp body 2, the operator places the mounting block 7 on the inner wall of the mounting shell 5. Then, the operator rotates the rotating block 15, which drives the bidirectional screw 14 to rotate. During the rotation of the bidirectional screw 14, the two sets of locking blocks 17 move relative to each other, and the locking blocks 17 are limited by the limiting rod 16 to ensure that the locking blocks 17 will not rotate during the movement. The locking blocks 17 then move towards the inner wall of the fixing groove 13. When they contact the inner wall of the fixing groove 13, the mounting block 7 is fixed. Next, the operator places the toothed block 20 on the inner wall of the toothed groove 19 to achieve the limiting connection between the rotating block 15 and the bidirectional screw 14. Finally, the operator fixes the bolt 21 to the inner wall of the threaded groove 22 by threaded connection, thereby completing the fixing of the fixing plate 18 and finally realizing the installation of the welding clamp body 2.

[0025] In a preferred embodiment: the outer wall of the heavy-duty rotating shaft body 3 is provided with a locking groove 11 and a limiting groove 12, and the inner wall of the placement groove 8 is fixedly fitted with a sealing shell 10.

[0026] In the above structure, the sealing shell 10 and the limiting groove 12 are used to seal the placement groove 8, so that the welding head 4 can perform better during operation. The locking groove 11 and the fixing component 9 are used to clamp and fix the heavy-duty rotating shaft body 3.

[0027] In a preferred embodiment: the fixing component 9 includes a spring 901, a connecting plate 902 is fixedly mounted on the outer wall of the spring 901, a fixing block 903 is fixedly mounted on the end of the connecting plate 902 away from the spring 901, one end of a steel rope 904 is fixedly mounted on the inner wall of the fixing block 903, a clamping block 905 is fixedly mounted on the other end of the steel rope 904, a support rod 906 is provided on the outer wall of the clamping block 905, a rotating rod 907 is rotatably connected to the inner wall of the support rod 906, and a pressure block 908 is fixedly mounted on the end of the connecting plate 902 near the fixing block 903.

[0028] In the above structure, during the process of fixing the heavy-duty rotating shaft body 3, the worker places the heavy-duty rotating shaft body 3 on the inner wall of the placement groove 8, so that it applies pressure to the pressure block 908. After the pressure block 908 bears the pressure, it will cause the connecting plate 902 to move on the inner wall of the placement groove 8. During the movement, the connecting plate 902 will apply pressure to the spring 901. The movement of the connecting plate 902 will simultaneously drive the fixing block 903 to move. When the fixing block 903 moves, it will pull the steel rope 904 to apply pressure to the clamping block 905. After being subjected to pressure, the clamping block 905 will drive the rotating rod 907 to rotate on the inner wall of the support rod 906, and finally make the clamping block 905 rotate toward the inner wall of the locking groove 11, thereby achieving the clamping and fixing of the heavy-duty rotating shaft body 3.

[0029] In a preferred embodiment: the spring 901 and the support rod 906 are both fixedly assembled with the inner wall of the placement groove 8, the clamping block 905 is fixedly assembled with the outer wall of the rotating rod 907, the clamping block 905 is adapted to the inner wall of the locking groove 11, and the limiting groove 12 is adapted to the inner wall of the sealing shell 10.

[0030] In the above structure, the fixing component 9 is limited by the placement groove 8 to prevent it from falling off during placement. The clamping block 905 is limited by the rotating rod 907 to prevent it from disengaging during rotation. The heavy-duty rotating shaft body 3 is clamped and fixed when the clamping block 905 is placed on the inner wall of the slot 11. The inner wall of the placement groove 8 is sealed when the limiting groove 12 is placed on the inner wall of the sealing shell 10.

[0031] In a preferred embodiment: the locking block 17 is slidably connected to the inner wall of the limiting rod 16, the fixing groove 13 is formed on the inner wall of the mounting shell 5, the toothed block 20 engages with the toothed groove 19, and the threaded groove 22 is formed on the outer wall of the rotating block 15.

[0032] In the above structure, the limiting rod 16 is used to limit the locking block 17 so that the locking block 17 will not rotate when moving. The fixing groove 13 and the locking block 17 are used to connect the mounting shell 5 and the mounting block 7. The toothed block 20 is placed on the inner wall of the toothed groove 19 to connect the rotating block 15 and the bidirectional screw 14. The threaded groove 22 and the bolt 21 are used to fix the fixing plate 18.

[0033] In a preferred embodiment, the toothed groove 19 is formed on the inner wall of the bidirectional screw 14, and the locking block 17 is adapted to the inner wall of the fixing groove 13.

[0034] In the above structure, the toothed groove 19 and toothed block 20 are used to limit the rotation block 15 and the bidirectional screw 14, so as to prevent the rotation block 15 from not driving the bidirectional screw 14 to rotate when it stops rotating. The locking block 17 is used to limit the mounting block 7 when it moves to the inner wall of the fixing groove 13.

[0035] Working principle: During the process of fixing the welding clamp body 2, the operator first places the mounting block 7 on the inner wall of the mounting shell 5, then rotates the rotating block 15. The rotation of the rotating block 15 drives the bidirectional screw 14 to rotate accordingly. During the rotation of the bidirectional screw 14, the two sets of locking blocks 17 move relative to each other, and the locking blocks 17 are limited by the limiting rod 16 to ensure that the locking blocks 17 will not rotate during the movement. Finally, the locking blocks 17 move towards the inner wall of the fixing groove 13, thereby fixing the mounting block 7. Next, the operator places the toothed block 20 on the inner wall of the toothed groove 19. The toothed block 20 limits the connection between the rotating block 15 and the bidirectional screw 14. Finally, the operator threads the bolt 21 to the inner wall of the threaded groove 22. The installation of the welding clamp body 2 is completed by fixing the fixing plate 18. During the process of fixing the heavy-duty rotating shaft body 3, the worker places the heavy-duty rotating shaft body 3 on the inner wall of the placement groove 8, so that the heavy-duty rotating shaft body 3 applies pressure to the pressure block 908. After being pressed, the pressure block 908 pushes the connecting plate 902 to move on the inner wall of the placement groove 8. At the same time, the connecting plate 902 applies pressure to the spring 901 during the movement. The movement of the connecting plate 902 also drives the fixing block 903 to move. When the fixing block 903 moves, it pulls the steel rope 904 to apply pressure to the clamping block 905. After being pressed, the clamping block 905 drives the rotating rod 907 to rotate on the inner wall of the support rod 906. Finally, the clamping block 905 rotates towards the inner wall of the locking groove 11, thereby achieving the clamping and fixing of the heavy-duty rotating shaft body 3.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
