Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the particular embodiments described herein are illustrative only and are not intended to limit the utility model, i.e., the embodiments described are merely some, but not all, of the embodiments of the utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.

Referring to fig. 1 to 3, in an embodiment of the present utility model, a clamping device for welding processing includes a base plate 1, wherein a driving cylinder 2, a first clamping assembly 3 and a second clamping assembly 4 are sequentially arranged on the base plate 1 along a length direction, and a connecting rod 31 is hinged on an output end of the driving cylinder 2; the first clamping component 3 and the second clamping component 4 are both hinged with the bottom plate 1, and the first clamping component 3 is also hinged with one end of the connecting rod 31, which is different from the driving cylinder 2.

Compared with the prior art, the clamping device for welding processing provided by the embodiment of the utility model has the advantages that the cylinder is linked with the first clamping component 3 and the second clamping component 4 through the connecting rod 31 and the second roller 21, and when the clamping device is used, the first clamping component 3 and the second clamping component 4 are driven to simultaneously clamp two workpieces to be welded by driving the cylinder 2 to extend out of the output end, so that the welding efficiency is improved.

The first clamping assembly 3 comprises two oppositely arranged first clamping arms 32, the middle part of each first clamping arm 32 is hinged to the bottom plate 1, the top of each first clamping part 33 is hinged to the connecting rod 31, the second clamping assembly 4 comprises two oppositely arranged second clamping arms 41, one ends of the two second clamping arms 41 are hinged to the bottom plate 1, the other ends of the two second clamping arms 41 are respectively provided with a second clamping part 44, the middle part of each second clamping arm 41 is rotatably provided with a first roller 42, and the tail end of the output end of the driving cylinder 2 is provided with a second roller 21.
