Two-way symmetrical displacement clamping device for automatic welding car

Abstract

The invention discloses a two-way symmetrical displacement clamping device for an automatic welding vehicle, which comprises a handle lever booster driving mechanism, an eight-link displacement direction conversion transmission mechanism, a connecting rod base plate (14), a connecting rod locking chassis (19) and Two sets of clamping wheel clamping devices; the handle lever booster drive mechanism and the connecting rod base plate (14) are fixed on the connecting rod locking chassis (19), and the eight-link displacement direction conversion transmission mechanism is fixed On the link base plate (14), the link base plate (14) is cross-shaped, and each arm is provided with a chute (141); the handle lever booster drive mechanism is connected to the right arc card The shaft seat (10) applies a driving force to the right arc card shaft seat (10), and is evenly transmitted to the two sets of clamping wheel clamping devices through the eight-link displacement direction conversion transmission mechanism to clamp the welding vehicle. It can ensure the firm connection between the welding car and the guide rail, and make the welding car run 360° around the pipeline.

Description

technical field [0001] The invention relates to the technical field of mechanical structures, in particular to a bidirectional symmetrical displacement clamping device for an automatic welding vehicle. Background technique [0002] With the wide application and development of pipeline transportation methods in related fields, people began to use a large number of high-precision pipeline automatic welding technology and equipment. When performing pipeline welding operations, the use of a reasonable clamping structure is conducive to improving the positional accuracy between the welding vehicle and the guide rail, thereby improving the welding quality of the welds of various pipeline products. The structural features of the welding clamping device of the pipeline automatic welding vehicle currently on the market are: a movable slider is set on one side of the clamping device, and the elastic force generated by spring compression is used to push the slider to move back and fort...
