A butt welding tool for inner and outer fork assembly

Abstract

The invention discloses an assembly welding tool of an inner and outer fork assembly in the field of assembly tools. The inner and outer fork assembly comprises two fork rods, a lengthened long shaftsleeve, a common long shaft sleeve and two short shaft sleeves. Connecting holes are formed in the head, the middle and the tail of each fork rod, and the two fork rods are arranged in parallel. The lengthened long shaft sleeve penetrates the connecting holes in the heads of the two fork rods. The common long shaft sleeve penetrates the connecting holes in the tails of the two fork rods. The two short shaft sleeves penetrate the connecting holes in the middles of the two fork rods correspondingly. The tail of a short oil cylinder support is in clamped connection to the common long shaft sleeve, and a long oil cylinder support is in clamped connection to the lengthened long shaft sleeve. The long oil cylinder support and the short oil cylinder support are in central symmetry and are provided with fixed holes. The welding tool comprises a workpiece mounting rack, an inner and outer fork part locating mechanism, a fastening mechanism, an oil cylinder support locating mechanism, a jackingmechanism and a clamping mechanism, and the inner and outer fork part locating mechanism, the fastening mechanism, the oil cylinder support locating mechanism, the jacking mechanism and the clamping mechanism are all fixed to the workpiece mounting rack. All parts of the inner and outer fork assembly are assembled on the welding tool, and the fixed point procedure is omitted.

Description

technical field [0001] The invention relates to the field of pairing tooling, in particular to an inner and outer fork assembly butt welding tooling. Background technique [0002] Welding fixture is a set of flexible fixtures for welding fixation, compression and positioning. It is mainly used for the welding of various weldable materials, as well as the welding of large, medium and small materials. Widely used in steel structures, various vehicle body manufacturing, rail transit welding, bicycle and motorcycle manufacturing, construction machinery, frames and boxes, pressure vessels, robot welding, sheet metal processing, metal furniture, equipment assembly, industrial pipelines (flanges) ) and other welding and detection systems. [0003] Most of the existing paired welding fixtures are separated from the welding fixtures, and the positioning, jacking and clamping mechanisms of the fixtures are still manually operated. There are many problems in this form of tooling: th...

Problems solved by technology

There are many problems in this form of tooling: the fixed point and welding tooling are separated, which takes up a lot of space in the workshop; the logistics time between clamping and welding processes is greatly increased, the operation is cumbersome, and the work efficiency is low; the welding tooling releases the freedom of some parts, due to welding deformation The influence of the workpiece causes the accuracy of the workpiece to be low
