[0020] Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution: a transformer assembly workbench convenient for fixing, including a workbench 1, an assembly table 2 and a servo motor 4. An assembly table 2 is arranged on the top of the workbench 1, and the assembly table 2 plays a role in supporting and placing the transformer. A rotating shaft 3 is welded at the center of the bottom end of the assembly table 2, and the rotating shaft 3 plays a role in supporting and connecting. The servo motor 4 is arranged at the center of the bottom end of the workbench 1, and the output end of the servo motor 4 is connected to the rotating shaft 3. By driving the rotating shaft 3 to rotate through the servo motor 4, the assembly table 2 can be driven to rotate, facilitating multi-angle installation and assembly after the transformer is fixed. Ball bearings 5 are arranged on both sides of the servo motor 4 between the workbench 1 and the assembly table 2. The ball bearings 5 play a certain supporting role and assist the assembly table 2 to rotate.

[0021] A driving cavity 6 is arranged in the middle of the assembly table 2. The inner wall of the driving cavity 6 is connected with a bidirectional threaded rod 7 through a bearing. The bidirectional threaded rod 7 can rotate in the driving cavity 6. Moving blocks 8 are threadedly connected to both sides of the bidirectional threaded rod 7 with opposite threads. When the bidirectional threaded rod 7 rotates, the two moving blocks 8 move in opposite directions. A rotating handle 9 is connected to one side of the assembly table 2, and the output end of the rotating handle 9 is connected to the bidirectional threaded rod 7. By rotating the rotating handle 9, the bidirectional threaded rod 7 can be driven to rotate.

[0022] Limit slots 10 are arranged on both sides of the upper surface of the assembly table 2, and the limit slots 10 play a limiting role. Screws 11 are welded to both sides of the top end of the moving block 8. The screws 11 rotate synchronously with the moving block 8. By rotating the rotating handle 9, the bidirectional threaded rod 7 is driven to rotate. When the bidirectional threaded rod 7 rotates, the two moving blocks 8 move in opposite directions, and the screws 11 rotate synchronously with the moving block 8, thereby driving the clamping plates 13 to fixedly clamp the assembled transformer. One end of the screw 11 away from the moving block 8 passes through the limit slot 10 and extends to the top of the assembly table 2.

[0023] A lifting mechanism 12 is sleeved on the middle part of the screw rod 11. The lifting mechanism 12 can drive the clamping plate 13 to move up and down to lift the transformer, which is convenient for lifting the bottom end of the transformer during the assembly process to facilitate assembly. The lifting mechanism 12 includes a fixed shell 121, a worm wheel 122, a thread 123, a worm 124 and a driving motor 125. One side inside the fixed shell 121 is connected with the worm wheel 122 through a bearing. The fixed shell 121 plays a role of fixed connection. The worm wheel 122 can rotate inside the fixed shell 121. The inner wall of the worm wheel 122 is provided with a thread 123. The thread 123 is in threaded connection with the screw rod 11. The rotation of the worm wheel 122 drives the thread 123 to rotate, so that the thread 123 moves up and down along the screw rod 11, thereby realizing the lifting movement of the worm wheel 122 and the fixed shell 6.

[0024] A worm 124 is arranged between the fixed shell 121. The worm 124 is connected with the fixed shell 121 through a bearing. The worm 124 can rotate inside the fixed shell 121. The threaded part of the worm 124 meshes with the worm wheel 122. The rotation of the worm 124 drives the worm wheel 122 to rotate. The outer wall of one side of the fixed shell 121 is connected with a driving motor 125. The output end of the driving motor 125 is connected with the worm 124. The driving motor 125 can drive the worm 124 to rotate. The rotation of the worm 124 drives the worm wheel 122 to rotate. The rotation of the worm wheel 122 drives the thread 123 to rotate, so that the thread 123 moves up and down along the screw rod 11, thereby realizing the lifting movement of the worm wheel 122 and the fixed shell 6, and driving the clamping plate 13 to move up and down, which is convenient for lifting the bottom end of the transformer during the assembly process to facilitate assembly.

[0025] One side of the fixed shell 121 close to the center of the assembly table 2 is connected with a clamping plate 13. The clamping plate 13 plays a role of clamping and fixing. The clamping plate 13 is in an L shape and can lift the transformer after clamping. A limit ring 14 is sleeved on the outer wall of the screw rod 11 at the top of the fixed shell 121. The limit ring 14 is connected with the clamping plate 13. The limit ring 14 plays a limiting role. The clamping directions of the two clamping plates 13 are opposite. A rubber pad 15 is arranged on the inner wall of the clamping plate 13. The rubber pad 15 plays a role of increasing the friction between the clamping plate 13 and the transformer, so that it is not easy to fall off. An electric telescopic rod 16 is arranged at the bottom end of the workbench 1. The electric telescopic rod 16 can drive the workbench 1 to move up and down, which is convenient for workers of different heights to carry out the assembly work of the transformer.

[0026] Working principle: When using a transformer assembly workbench that is convenient for fixing, the transformer to be assembled is placed on the assembly table 2. By rotating the rotary handle 9, the bidirectional threaded rod 7 is driven to rotate. The rotation of the bidirectional threaded rod 7 drives the two groups of moving blocks 8 to move in opposite directions. The screw 11 rotates synchronously with the moving block 8 to drive the clamping plate 13 to fixedly clamp the assembled transformer. When it is necessary to assemble the bottom of the transformer while lifting it, the driving motor 125 can drive the worm 124 to rotate. The rotation of the worm 124 drives the worm gear 122 to rotate. The rotation of the worm gear 122 drives the screw 123 to rotate, so that the screw 123 moves up and down along the screw 11, thereby realizing the lifting movement of the worm gear 122 and the fixed shell 6, driving the clamping plate 13 to lift, which is convenient for lifting the bottom end of the transformer during the assembly process to facilitate assembly. The clamping plate 13 plays a role in clamping and fixing. The clamping plate 13 is in an L shape and can lift the transformer after clamping. The rubber pad 15 plays a role in increasing the friction between the clamping plate 13 and the transformer, making it not easy to fall off. An electric telescopic rod 16 is provided at the bottom end of the workbench 1. The electric telescopic rod 16 can drive the workbench 1 to perform a lifting movement, which is convenient for workers of different heights to perform the assembly work of the transformer.
