Welding device for placing workpiece

Abstract

The invention discloses a welding device for placing workpieces. The device comprises a top seat, supporting legs and a welding table surface, the top seat comprises a main seat body, and sliding grooves which extends forwards and backward are arranged in the main seat body in a left-right commensurate mode, wherein the opening parts of the sliding grooves face outside; the front end of the main seat body is provided with a middle rotating groove which is located at the left middle part and the right middle part; a first belt wheel is rotatably mounted in the middle rotating groove through a rotating shaft, and a side rotating groove is formed in the front end of the sliding groove; a communicating groove which communicates with the side rotating groove and the middle rotating groove is formed between the side rotating groove and the middle rotating groove, and a front sliding block and a rear sliding block can be installed in the sliding groove in a sliding mode; the front sliding block and the rear sliding block are correspondingly provided with a front spiral rod and a rear spiral rod in a spiral fit manner, the front spiral rod and the rear spiral rod are fixedly connected, anda second belt wheel is installed in the side rotating groove; the second belt wheel is fixedly connected with the front screw rod, and a belt is arranged on the first belt wheel and the second belt wheel; and a front connecting rod extending forwards is fixedly arranged at the outer side end of the front sliding block, and a rear connecting rod extending backwards is fixedly arranged at the outerside end of the rear sliding block.

Description

technical field [0001] The invention relates to the field of welding, in particular to a welding device for arranging workpieces. Background technique [0002] When workers perform welding operations, they usually place the welding machine or the required welding workpiece on the workbench, so as to facilitate the welding operation. The existing welding workbench usually has a simple design and structure, and the length of its legs cannot be adjusted up and down, and the welding workbench The welding table is fixedly connected with the feet. After long-term welding operation, the welding table is most likely to be damaged, so the welding table needs to be replaced. The existing welding table is usually unable to be replaced, and the entire welding table needs to be replaced, which is a waste of cost. Moreover, the distance between each leg of the existing welding workbench cannot be adjusted, so that the size of the table top of the welding workbench cannot be adjusted, so t...
