Problems solved by technology

It does not have the function of adjusting the gap between tailor welds, that is, it is not suitable for the requirements of laser wire-filled welding of aluminum-silicon-coated thermoforming steel, that is, the gap between welds needs to be adjustable within the range of 0-1mm
The width of the tailor weld gap will affect the chemical composition of the weld metal, and then affect the mechanical properties of the weld

Abstract

The invention discloses a combined tool clamp for automobile door ring laser tailor-welded plates. The combined tool clamp comprises a fixed chuck assembly (10), a gap adjusting chuck assembly (20) and a round hole base (30); the round hole base comprises a substrate (31) providing with a plurality of round holes (34); the fixed chuck assembly comprises two positioning parts, a first chuck supporting seat (16), a first supporting rod (17) and a first height adjusting nut (18); the gap adjusting chuck assembly comprises a gap adjusting sheet (21), a third cylinder (22), a second chuck supporting seat (23), a second supporting rod (26) and a second height adjusting nut (27); and the first supporting rod and the second supporting rod are arranged on the substrate through the round holes, thefixed chuck assembly is adjusted up and down through the first supporting rod by means of the first height adjusting nut, and the gap adjusting chuck assembly is adjusted up and down through the second supporting rod by means of the second height adjusting nut. The combined tool clamp can adapt to all types of door rings, reduces the mold cost, meets the requirements of testing and batch production and shortens the production period.

Description

technical field [0001] The invention relates to a manufacturing and processing equipment of a steel plate, in particular to an assembly fixture of a laser tailor welded sheet for an automobile door ring. Background technique [0002] At present, door knocker products of hot-formed steel laser tailor welding have begun to be widely used on automobile body-in-white. Door knockers (commonly known as automobile door frames) come in various forms, ranging from tailor-welded 2 steel plates to 6 tailor-welded steel plates, and the shape of each piece of raw material is also different. The traditional method is to develop a set of positioning fixtures for each type of door knocker. The cost increases and the manufacturing cycle is long. Especially in the test stage, a set of door knockers may only produce a small number of pieces such as dozens or hundreds of pieces, but still need A set of positioning fixtures was specially developed for this set of door knockers. Once it is final...
