DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, a clamping and flipping device for a spot welding machine comprises: a bottom plate 1, the upper end of which is fixedly connected to two fixing frames 2; a positioning mechanism 3, which is arranged at the upper end of the fixing frames 2; wherein the positioning mechanism 3 comprises a flipping assembly 32 installed at the upper end of the fixing frames 2, a clamping assembly 31 is installed on the surface of the flipping assembly 32, and the other end of the clamping assembly 31 on one side extends to the inside of the adjacent clamping assembly 31;

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the clamping assembly 31 includes a clamping frame 311 arranged on the surface of the flip assembly 32, one side of the clamping frame 311 is fixedly connected to a cylinder 312, the telescopic end of the cylinder 312 is fixedly connected to a connecting block 313, one end of the connecting block 313 penetrates the inner side of the clamping frame 311 and is fixedly connected to a moving plate 314, a clamping plate 316 is arranged on the inner side of the clamping frame 311, and a side of the moving plate 314 away from the cylinder 312 is fixedly connected to a plurality of bottom wedges 315, and the lower end of the clamping plate 316 is fixedly connected to the inner side of the clamping frame 311. A plurality of upper wedge blocks 318 are fixedly connected, and the upper wedge blocks 318 are slidably connected to the upper inclined surfaces of the adjacent bottom wedge blocks 315. The end of the clamping frame 311 is threadedly connected with an adjusting bolt 319, and the adjusting bolt 319 is arranged inside the adjacent clamping frame 311. The end of the adjusting bolt 319 passes through the adjacent clamping frame 311 and extends to the outside of the adjacent clamping frame 311. The upper end of the clamping plate 316 is fixedly connected with a guide rod 317, and the upper end of the guide rod 317 passes through the upper part of the clamping frame 311.

[0026] When the two metal plates are placed above the clamping plate 316 and between the top wall of the clamping frame 311, the cylinder 312 is driven to drive the connecting block 313 to move synchronously through the telescopic end of the cylinder 312. At this time, the connecting block 313 drives the moving plate 314 to move synchronously inside the clamping frame 311, and also drives multiple bottom wedge blocks 315 to move simultaneously. At this time, the bottom wedge block 315 pushes the upper wedge block 318 to move upward through the inclined surface. When the upper wedge block 318 moves upward, the clamping plate 316 moves upward, and when the clamping plate 316 moves upward, When the clamping plate 316 is moved horizontally with the bottom wedge block 315 under the guidance of the guide rod 317, the clamping plate 316 is kept stable for longitudinal movement, so that the clamping plate 316 drives the edge of the plate to fit the inner top wall of the clamping frame 311, thereby completing the clamping of the edge of the plate. At the same time, the device can also set the adjustment bolt 319 inside the adjacent clamping frame 311. At this time, the tightening effect of the adjustment bolt 319 can be achieved, so that the clamping width of the two clamping frames 311 on the edge of the plate can be adjusted, so that different plates can be clamped.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the flip assembly 32 includes a fixed ring 321 fixedly connected to the upper end of the fixed frame 2, the inner wall of the fixed ring 321 is rotatably connected to a rotating seat 323, the rotating seat 323 is slidably connected to the surface of the clamping frame 311, the surface of the rotating seat 323 is fixedly connected to a spring 324, the other end of the spring 324 is fixedly connected to a resistance block 325, one side of the resistance block 325 is fixedly connected to a connecting rod 326, one side of the fixed ring 321 is fixedly connected to a side frame 322, a side of the side frame 322 away from the fixed ring 321 is provided with a card slot 328, the connecting rod 326 penetrates to the outside of the side frame 322 and is fixedly connected to an operating handle 327, the surface of the operating handle 327 is carded with the inner wall of the card slot 328;

[0028] When flipping is required, the operating handle 327 can be manually pulled to release the locking effect between the operating handle 327 and the slot 328, and the connecting rod 326 can be used to drive the resistance block 325 to separate from the clamping frame 311. At this time, the rotating seat 323 can drive the clamping frame 311 to flip. After flipping one hundred and eighty degrees, the spring 324 can be used to drive the resistance block 325 to reset, so that the resistance block 325 and the surface of the clamping frame 311 fit tightly. At the same time, the end of the resistance block 325 is provided with soft rubber teeth to increase friction. At this time, the operating handle 327 and the slot 328 form a locking effect again, and the connecting rod 326 drives the resistance block 325 to form a locking effect with the surface of the clamping frame 311. At this time, the clamping frame 311 will be unable to rotate, thereby maintaining the stability of the work.

[0029] When the utility model is in use, two metal plates are placed above the clamping plate 316 and between the inner top wall of the clamping frame 311. The telescopic end of the driving cylinder 312 drives the moving plate 314 to move synchronously inside the clamping frame 311 through the connecting block 313. The multiple bottom wedges 315 follow the moving plate 314 to move against the upper wedge 318 to move upward. Under the guidance of the guide rod 317, the clamping plate 316 follows the upward clamping plate 316 to drive the edge of the plate toward the inner top wall of the clamping frame 311. When flipping, manually pull the operating handle 327 to separate the card slot 328, and drive the resistance block 325 to separate from the clamping frame 311 through the connecting rod 326. At this time, the rotating seat 323 drives the clamping frame 311 to flip. After the flipping is completed, the spring 324 drives the resistance block 325 to return to its original position. The resistance block 325 fits tightly with the surface of the clamping frame 311, and the connecting rod 326 drives the resistance block 325 to form a clamping effect with the surface of the clamping frame 311. At this time, the clamping frame 311 will be unable to rotate.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
