Floor assembly welding clamp

Abstract

The invention provides a floor assembly welding clamp capable of achieving horizontal swing transposition and high-precision locating and clamping. The floor assembly welding clamp comprises a workbench and a swing arm. One end of the swing arm is arranged on the edge of the workbench in a hinged manner, and the other end of the swing arm is in a free overhanging state. The swing arm is connected with a first drive mechanism and driven by the first drive mechanism to rotate around a first hinge shaft at one end of the swing arm. When the swing arm rotates, an arm rod of the swing arm can be rotated to the position above a workpiece A placed on the workbench or rotated to the edge of the workbench. A clamping mechanism and a locating mechanism which are used for tightening and fixing the workpiece and / or implementing workpiece locating are connected to the swing arm. The swing arm of the floor assembly welding clamp swings horizontally, and potential safety hazards are greatly reduced; position switching of a work station and a to-be-done station can be achieved simply through simple transposition of the clamp in a horizontal plane, and arrangement of subordinate accessories is facilitated; and meanwhile the locating precision is high, and operation is convenient.

Description

technical field [0001] The invention relates to the field of automobile manufacturing technology, in particular to a floor assembly welding jig. Background technique [0002] The floor assembly is a very important part of the lower part of the car body. It mainly carries the seat, spare tire, and fuel tank as well as load-bearing tasks. The floor assembly is usually made of the left body, right body, and middle channel body. It is generally large in size. The length of the jig arm used for parts positioning and clamping is up to 700mm. [0003] At present, in the automobile body-in-white manufacturing process, the welding jig of the floor assembly usually adopts a vertical flip method. When the jig is opened, the jig arm is turned upside down around the horizontal axis, and the height from the ground to the top of the jig arm reaches 1780mm, which has exceeded the average of ordinary people. Height (1700 ~ 1740mm). When assembling the stamped parts of the front floor, eith...

AI Technical Summary

Problems solved by technology

When assembling the stamped parts of the front floor, either the stamped parts are lifted above the head, or the relay is passed through the clamp arm, which is inconvenient and affects safety. After the welding is completed, the clamp arm is in the process of opening. The air return speed is too fast, the angle of the clamp arm is too large, and there is a hidden danger of personal contact and injury
