[0033] It should be noted that the base plate 1 is provided with a first clamping assembly 12 and a second clamping assembly 13, a supporting leg 11 is provided at the bottom of the base plate 1, the first clamping assembly 12 includes a first slider 122 rotatably mounted inside the base plate 1, a first threaded rod 121 is threadedly mounted on the outer wall of the first slider 122, a third telescopic rod 123 is provided at the top of the first threaded rod 121, a first mobile bin 124 is fixedly mounted at the end of the third telescopic rod 123, a second threaded rod 125 is rotatably mounted inside the first mobile bin 124, and the second The outer wall of the threaded rod 125 is threadedly mounted with a first clamping block 126, and the side wall of the first clamping block 126 is generally used for welding and clamping the metal plate. The second clamping assembly 13 includes a third threaded rod 131 rotatably mounted inside the edge of the bottom plate 1, and the outer wall of the third threaded rod 131 is threadedly mounted with a second slider 132, and the top of the second slider 132 is fixedly mounted with a fourth telescopic rod 133, and the end of the fourth telescopic rod 133 is fixedly mounted with a second mobile bin 134, and the interior of the second mobile bin 134 is slidably provided with a first welding head 16, such as Figure 2As shown, a first welding plate 14 and a second welding plate 15 are placed on the first clamping components 12 on the bottom plate 1. The height of the first welding plate 14 is greater than the height of the second welding plate 15. During welding, the bottoms of the first welding plate 14 and the second welding plate 15 need to be in the same horizontal plane. When the first welding plate 14 and the second welding plate 15 need to be welded, the position of the first clamping component 12 clamping the first welding plate 14 and the second welding plate 15 is adjusted so that the welding interface of the first welding plate 14 and the second welding plate 15 is in the center position of the bottom plate 1. Then, the motor can be started to drive the third threaded rod 131 to rotate, and the rotation of the third threaded rod 131 drives the second slider 132 moves, and the second slider 132 moves to drive the fourth telescopic rod 133 and the second mobile bin 134 to adjust the position of the first welding head 16, and the side wall of the first welding head 16 is provided with a third fixed plate 161, and the interior of the third fixed plate 161 is provided with a grinding device 2. When the second clamping assembly 13 is started to adjust the position of the first welding head 16, the grinding device 2 is driven to move toward the interface of the first welding plate 14 and the second welding plate 15 at the same time. When the grinding device 2 moves, the first welding head 16 slides inside the second mobile bin 134, thereby facilitating the welding of the surface of the grinding block 23 inside the grinding device 2 with the first welding plate 14 and the second clamping assembly 13 The first welding plate 14 and the second welding plate 15 are in contact with each other, and the gap with a height difference on the center line of the bottom plate 1 is contacted, and the grinding device 2 is driven by a motor to start. After the position of the first welding head 16 is adjusted, the interface position of the first welding plate 14 and the second welding plate 15 is welded. During welding, the grinding block 23 inside the grinding device 2 rotates to grind the gap between the first welding plate 14 and the second welding plate 15 to be welded, thereby preventing the problem of poor welding effect caused by oxidation on the surface. A plurality of grinding blocks 23 are arranged on the grinding device 2. When the plurality of grinding blocks 23 are attached to the raised part of the first welding plate 14, the grinding is performed. During grinding, an uneven surface will appear on the welding position of the side wall of the first welding plate 14. During welding, the multiple grinding blocks 23 can rotate to adapt to the uneven surface, so as to grind the raised position of the first welding plate 14. The surface debris of the grinding block 23 after grinding will affect the grinding effect of the grinding block 23, and the debris will produce bubbles due to the high temperature of welding. Therefore, in order to improve the welding effect, an adsorption device 3 is provided on the side of the third fixed plate 161, so that the surface debris after grinding by the multiple grinding blocks 23 can be collected, and at the same time, the debris falling on the first welding plate 14 and the second welding plate 15 is reduced, thereby improving the welding and grinding effect of copper plates with different heights.

[0034] like Figures 3 to 6As shown, the outer wall of the first welding head 16 is provided with a third fixed plate 161, the grinding device 2 includes a first gear 22 rotatably mounted inside the third fixed plate 161, a top support block 21 is rotatably mounted inside the first gear 22, the end of the top support block 21 is fixedly mounted on the top of the third fixed plate 161, a first limiting rod 24 is fixedly mounted on the bottom end of the top support block 21, a plurality of third limiting blocks 28 are fixedly mounted on the outside of the first limiting rod 24, and the outer wall of the third limiting block 28 is connected to the two adjustment components 2 9 is fixedly installed, and the two adjusting components 29 are symmetrically installed. The end of the adjusting component 29 is fixedly installed with a second limit block 26, and the outer wall of the second limit block 26 is rotatably installed with a first limit rod 24; the transmission member includes a first transmission component 25 fixedly installed on the inner upper part of the first limit rod 24, the end of the first transmission component 25 is fixedly installed with the bottom end of the first gear 22, and the lower part of the inner wall of the first limit rod 24 is fixedly installed with a second transmission component 27, and the multiple grinding blocks 23 are connected through the second transmission component 27.

[0035] It should be noted that when it is necessary to drive the grinding block 23 to rotate, the motor is first used to drive the first gear 22 to rotate, and the rotation of the first gear 22 drives the first transmission assembly 25 to rotate, and the rotation of the first transmission assembly 25 can drive the grinding block 23 of the outer wall to rotate, and the lower end of the inner wall of the grinding block 23 is fixedly connected with the second transmission assembly 27, and multiple grinding blocks 23 are connected and transmitted through the second transmission assembly 27, thereby driving the multiple grinding blocks 23 to rotate, and the lower end of the top support block 21 is provided with a first limit rod 24, and the first limit rod 24 The outer wall is fixedly mounted with a plurality of third limit blocks 28 and adjustment components 29, the end of the adjustment component 29 is fixedly connected to the second limit block 26, and the grinding block 23 is mounted on the outer wall of the second limit block 26, thereby limiting the grinding block 23. The grinding block 23 can adapt to the welding grinding surface of the first welding plate 14, and the center of the grinding block 23 and the third limit block 28 is kept in the same horizontal plane. At the same time, the plurality of grinding blocks 23 can be staggered with each other, and the plurality of grinding blocks 23 can rotate synchronously, thereby achieving a grinding effect.

[0036] like Figures 5 and 6 As shown, the first transmission assembly 25 includes a first fixed block 251 fixedly mounted on the upper inner wall of the grinding block 23, a second rotating block 252 is rotatably mounted inside the first fixed block 251, a fifth telescopic rod 253 is fixedly mounted on the side wall of the second rotating block 252, a third rotating plate 254 is fixedly mounted on the end of the fifth telescopic rod 253, a second fixed block 255 is rotatably mounted inside the third rotating plate 254, and the top end of the second fixed block 255 is fixedly mounted on the bottom end of the first gear 22.

[0037] It should be noted that when the first gear 22 rotates and drives the first transmission assembly 25 to rotate, it drives the first transmission assembly 25 to rotate with the first limit rod 24 as the center. The rotation of the first transmission assembly 25 drives the grinding block 23 to rotate. The grinding block 23 adapts to the uneven welding surface, which will cause the center of the grinding block 23 to deviate from the center of the first limit rod 24. The adjusting assembly 29 adjusts the position of the second limit block 26, thereby driving the second limit block 26 to adjust the position of the grinding block 23. When the center of the grinding block 23 is different from the center of the first limit rod 24, the second fixed block 255 is fixedly connected to the first gear 22, and the first fixed block 251 is connected to the grinding block 23, so that the fifth telescopic rod 253 can be extended and retracted during the rotation, thereby achieving the purpose of driving the grinding block 23 to rotate.

[0038] like Figure 6 to Figure 7 As shown, the adjustment component 29 includes a first hollow column 291 fixedly mounted on the outer wall of the third limit block 28, a blocking block 293 is slidably mounted inside the first hollow column 291, a second telescopic column 292 is fixedly mounted on the side wall of the blocking block 293, a fourth spring 294 is fixedly mounted inside the first hollow column 291, an end of the fourth spring 294 is fixedly mounted on one side wall of the blocking block 293, a fifth spring 295 is fixedly mounted on the other side wall of the blocking block 293, an end of the fifth spring 295 is fixedly mounted on the inner wall of the first hollow column 291, and the fourth spring 294 and the fifth spring 295 make the blocking block 293 be located at the center position inside the first hollow column 291.

[0039] It should be noted that when the grinding block 23 is close to the side of the first welding plate 14, the uneven protrusions on the side of the first welding plate 14 will lift up the grinding block 23, and the grinding block 23 will drive the second limit block 26 to lift up the second telescopic column 292, and the end of the second telescopic column 292 is provided with a blocking block 293 and a fifth spring 295 and a fourth spring 294, and the end of the first hollow column 291 is fixedly installed on the outer wall of the third limit block 28. Therefore, when the second limit block 26 is not concentric with the first limit rod 24, the rotation of the first gear 22 can still drive the rotation of multiple first transmission assemblies 25, thereby realizing the synchronous rotation of multiple non-concentric grinding blocks 23.

[0040] like Figure 6 to Figure 7As shown, the first transmission assembly 25 includes a first fixed block 251 fixedly mounted on the upper inner wall of the grinding block 23, a second rotating block 252 is rotatably mounted inside the first fixed block 251, a fifth telescopic rod 253 is fixedly mounted on the side wall of the second rotating block 252, a third rotating plate 254 is fixedly mounted on the end of the fifth telescopic rod 253, a second fixed block 255 is rotatably mounted inside the third rotating plate 254, and the top end of the second fixed block 255 is fixedly mounted on the bottom end of the first gear 22.

[0041] It should be noted that, since the first gear 22 needs to drive the first transmission assembly 25 to rotate when it rotates, and the rotation of the first transmission assembly 25 thereby drives the multiple grinding blocks 23 to rotate, when the distance between the grinding block 23 and the first limiting rod 24 changes during the rotation process, the fifth telescopic rod 253 can be extended and retracted to adapt to the change in the distance between the edge of the grinding block 23 and the top support block 21, thereby achieving the effect of synchronously driving the multiple grinding blocks 23 to rotate when the first gear 22 rotates.

[0042] like Figure 6 to Figure 7 As shown, the adjustment component 29 includes a first hollow column 291 fixedly mounted on the outer wall of the third limit block 28, a blocking block 293 is slidably mounted inside the first hollow column 291, a second telescopic column 292 is fixedly mounted on the side wall of the blocking block 293, a fourth spring 294 is fixedly mounted inside the first hollow column 291, an end of the fourth spring 294 is fixedly mounted on one side wall of the blocking block 293, a fifth spring 295 is fixedly mounted on the other side wall of the blocking block 293, an end of the fifth spring 295 is fixedly mounted on the inner wall of the first hollow column 291, and the fourth spring 294 and the fifth spring 295 make the blocking block 293 be located at the center position inside the first hollow column 291.

[0043] It should be noted that, since the third limit block 28 and the second limit block 26 need to maintain the same horizontal plane, an adjustment component 29 is provided at the connection position of the third limit block 28 and the second limit block 26. When the grinding block 23 drives the second limit block 26 to move, so that the center of the second limit block 26 is different from that of the first limit rod 24, the two second telescopic columns 292 and the baffle block 293 can be driven to slide inside the first hollow column 291, and the two side walls of the first hollow column 291 are provided with a fourth spring 294. In the initial state, the fourth spring 294 is in the center position, so the grinding block 23 is in a concentric position with the first limit rod 24. When the center of the circle changes, the second telescopic column 292 and the baffle block 293 slide inside the first hollow column 291, and the grinding block 23 is in the same horizontal plane with the second limit block 26 and the third limit block 28. Then the fifth telescopic rod 253 inside the first transmission component 25 is extended and retracted, so as to achieve the effect of driving the first gear 22 to drive the grinding block 23 to rotate.

[0044] like Figure 5 As shown, a protrusion is provided at the bottom end of the grinding block 23 to be connected to the second transmission assembly 27 . The second transmission assembly 27 has the same structure as the grinding block 23 . The grinding block 23 and the second transmission assembly 27 are staggeredly installed inside the grinding block 23 .

[0045] It should be noted that a protrusion is provided at the bottom end of the grinding block 23 and is connected to the second transmission assembly 27. The second transmission assembly 27 has the same structure as the grinding block 23. The grinding block 23 and the second transmission assembly 27 are staggeredly installed inside the grinding block 23 to achieve the purpose of the first gear 22 driving the grinding block 23 to rotate through the first transmission assembly 25 and the second transmission assembly 27.
