[0035] Lifting appliance moving assembly 200 includes rotary top seat 210 arranged at the terminal of wrist joint 160, fixed top seat 220 is installed at the bottom of rotary top seat 210, fixed top seat 220 is tightly welded with fixed block 230 at the bottom, fixed block 230 is tightly welded with clamping box 240 at the bottom, motor 250 is arranged at the both sides of clamping box 240, threaded rod 260 is arranged in the inside of clamping box 240, and a plurality of bolts 280 are threadedly connected at the top of clamping box 240;

[0036] Clamping assembly 300 includes clamp plate 310 arranged at the bottom of clamping box 240, moving block 320 is tightly welded at the top of clamp plate 310, protruding block one 340 is tightly welded at one side of clamp plate 310, and protruding block two 370 is tightly welded at the other side of clamp plate 310.

[0037] Meanwhile, in order to the stability of the whole lifting appliance, specifically, a plurality of screw holes are formed at the top of fixed part 110, a plurality of hexagon bolts are threadedly connected in the screw holes, and the size of the four annular arrays of fixed part 110 matches with the size of base 120.

[0038] Further, in order to facilitate the fixation of motor 250, specifically, a plurality of grooves are formed at the top of clamping box 240, and fixed clips are tightly welded in the inner cavities of the grooves.

[0039] It is worth mentioning that in order to prevent the clamping assembly 300 from falling off the threaded rod 260, specifically, the outer wall of the threaded rod 260 is tightly welded with a plurality of limiting blocks 270, the size of the limiting block 270 matches the size of the threaded rod 260, and the threads on both sides of the threaded rod 260 are arranged in opposite directions.

[0040] When the article needs to be clamped, the rotating top seat 210 rotates to drive the fixed top seat 220 at the bottom to rotate together with the fixed block 230 and the clamping box 240, which facilitates the alignment of the article to be welded and the preliminary positioning. Subsequently, the motors 250 on both sides of the clamping box 240 are started to drive the threaded rod 260 to rotate, so that the two clamp plates 310 on the threaded rod 260 move in opposite directions along the threads, forming a clamp to clamp the article. The protruding block one 340 and the protruding block two 370 at the bottom of both sides of the two clamp plates 310 facilitate the support of the bottom edge of the article. The above structure enables the clamping assembly 300 to clamp the article from the outside through the protruding block two 370 on one side of the clamp plate 310, and to clamp the article from the inside through the protruding block one 340 on the other side of the clamp plate 310.

[0041] It is worth noting that in order to match the groove on the top of the clamping box 240, specifically, the side of the motor 250 is tightly welded with a clamping block, and the size of the clamping block matches the size of the groove on the top of the clamping box 240 and the fixed clamp.

[0043] In some embodiments, in order to further optimize the clamping effect of the welding production line lifting appliance on the article and reduce the damage to the article, special attention is paid to the design of the contact surface between the clamp plate 310 and the article. Specifically, the one side of the clamp plate 310 is not only provided with the rubber pad one 330, but the other side is also equipped with the rubber pad two 360. Both of the rubber pads are made of materials with high elasticity, wear resistance and certain buffering capacity, which can effectively disperse the pressure of the clamp plate on the article during clamping, avoiding scratches or indentations caused by direct metal contact. In addition, the softness of the rubber pad can also absorb vibrations to a certain extent, ensuring that the article can remain stable and undamaged during lifting and welding. This design not only improves the clamping safety and reliability of the lifting appliance, but also significantly improves the overall yield and quality of the articles on the production line.

[0044] Subsequently, in order to clamp the article in different ways, specifically, the bottom of the clamp plate 310 is provided with an electromagnet 350, which is electrically connected with the motor 250;

[0045] The electromagnet 350 at the bottom of the clamp plate 310 can generate magnetic force to adsorb the metal article by electricity, which is convenient for welding, and the clamping assembly 300 has three clamping modes, which can adopt different clamping modes according to the different structures, materials and sizes of the article, so that the lifting appliance has higher universality and practicality.

[0046] In addition, the circuits, electronic components and modules involved in the utility model are prior art, and those skilled in the art can realize them without further description, and the content protected by the utility model does not involve improvement of internal structure and method;

[0047] The device or equipment model involved in the present application is as follows:

[0048] Motor 250: Y160M-4.

[0049] Working principle:

[0050] When the device works, the welding production line lifting appliance is stably connected with the production line through the fixing piece 110. The motor 250 is started, and the motor drives the threaded rod 260 to start rotating. Since the threads on both sides of the threaded rod 260 are opposite, the forward and reverse rotation of the motor 250 can drive the moving block 320 to move on the threaded rod 260, thereby adjusting the position of the clamp plate 310. The limiting block 270 ensures that the moving block 320 moves stably and does not fall off. With the movement of the moving block 320, the clamp composed of the two clamp plates 310 gradually approaches the article for clamping. At the same time, the rubber pad one 330 and the rubber pad two 360 play a buffering protection role, preventing the clamp plate 310 from causing damage to the article. The multi-stage rotation design of the rotating seat 130, the upper arm joint 140, the forearm joint 150 and the wrist joint 160 enables the lifting appliance to flexibly adjust the angle and position of the article to adapt to different welding requirements. After the article is stably clamped and adjusted to the appropriate position, the welding production line can start the welding work. After the work is completed, the motor 250 is reversed, the clamp plate 310 releases the article, and the lifting appliance is ready to clamp the next welding piece to be welded, the whole device is simple and effective, and the working efficiency is improved.

[0051] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
