Clamp for automobile welding operation

Abstract

The invention discloses a clamp for automobile welding operation. Vertical rods are arranged on the two sides of a base. Rotating shafts are arranged on the two sides of a mounting frame and rotationally connected with the vertical rods correspondingly. A plurality of hydraulic cylinders pointing to the inner side of the mounting frame are mounted on the inner side of the mounting frame. A chain transmission assembly is installed between the base and one rotating shaft and used for driving the mounting frame to rotate and keeping the stop angle of the mounting frame. A manipulator is electrically connected with the plurality of hydraulic cylinders and used for driving the hydraulic cylinders to do telescopic motion. Through control over the hydraulic cylinders in the mounting frame, automobile parts of different sizes can be clamped and fixed, and control is carried out through the manipulator, so that control is more convenient; and rotation control over the mounting frame is achieved through the chain transmission assembly, adjustment of the mounting frame at different angles can be achieved, the clamp can adapt to welding operation at different angles, the overall structure is simple, the universality is high, and angle adjustment is flexible.

Description

technical field [0001] The invention relates to the technical field of automobile welding, and more specifically relates to a fixture used for automobile welding operations. Background technique [0002] At present, in the automobile welding fixture, the automobile parts are clamped by the fixture to facilitate manual assembly, welding, maintenance, etc., which improves the production efficiency and product accuracy. [0003] However, the existing automobile welding fixtures have poor versatility, especially for some larger parts, such as car doors of different sizes, which cannot be uniformly fixed. Moreover, for the existing fixing methods, they are generally non-adjustable. After the car door is fixed, it can only maintain an angle, and it cannot be performed when the welding operation needs to be switched. [0004] Therefore, how to provide a clamp for automobile welding operation with strong versatility and flexible angle adjustment is an urgent problem to be solved by...
