Clamp, clamping method, welding system and welding method

Abstract

The invention discloses a clamp, a clamping method, a welding system and a welding method. The clamp comprises a positioner, a first clamping structure and a second clamping structure, wherein the positioner is provided with a first position changing mechanism and a second position changing mechanism; the first clamping structure comprises a first clamp plate, a first clamping assembly, a first driving part, a first limiting assembly and a second limiting assembly; the first clamping assembly comprises a first clamping part and a second clamping part; the second clamping structure is used forclamping a product to be clamped in the second direction and the third direction; the first driving part is used for driving the first clamping assembly; the first clamping part moves in the second direction; the first clamping part is matched with the first limiting assembly to clamp a rack of an agricultural machine in the second direction; the second clamping part moves in the third direction;the second clamping part is matched with the second limiting assembly to clamp the rack of an agricultural machine in the third direction, and then the positioner is moved; therefore, the rack of theagricultural machine is clamped by the clamp in the first direction, the all-directional clamping is achieved, the matching precision of all the assemblies is guaranteed, and the rejection rate of therack of the agricultural machine is reduced.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a fixture, a clamping method, a welding system and a welding method. Background technique [0002] Existing agricultural machinery frames are generally manufactured by welding process. Since most of the components welded into agricultural machinery frames are irregularly shaped components, conventional welding fixtures cannot clamp the agricultural machinery frame in all directions, making the welding between components There are often misalignment of positions, or the welding surfaces between components cannot be contacted, so that the parameters such as welding strength, weld quality and product size of the agricultural machinery frame cannot be effectively guaranteed, which reduces the quality of the finished product of the agricultural machinery frame and makes the agricultural machinery The scrap rate of racks is high. [0003] Therefore, how to reduce the reject rate of t...
