Problems solved by technology

There are many problems in this form of tooling: the separation of pointing and welding tooling 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 degree of freedom of some parts. The influence of deformation causes the accuracy of the workpiece to be low

Embodiment 1

[0024] see figure 1 , figure 1 It is a schematic diagram of the butt welding tooling of the inner fork group. The workpiece mounting frame 24 is a rectangular frame structure. Three groups of symmetrical through holes are provided on both sides of the frame body. The positions of the through holes are determined by the positions of the long shaft sleeve 111 and the short shaft sleeve 12 of the fork rod 13 . First the fork rod 13 is placed on the workpiece mounting frame 24, the end positioning device 211 is fixed on the workpiece mounting frame 24 and is positioned at one end of the fork rod 13 to carry out lateral preliminary positioning to the position of the fork rod 13; the width positioning device 212 is fixed on the workpiece On the mounting frame 24 and outside the fork rod 13 , the width of the fork rod 13 is preliminarily positioned by the width positioning device 212 . The approximate position of the fork rod 13 is defined by the end positioning device 211 and the ...

Embodiment 2

[0027] see figure 2 , figure 2 It is a schematic diagram of the welding tooling structure of the inner fork parts with two long shaft sleeves 111 of different lengths. The workpiece mounting frame 24 is a rectangular frame structure, and two groups of symmetrical through holes are opened on both sides of the frame body, and the positions of the through holes are determined by the positions of the long shaft sleeve 111 and the short shaft sleeve 12 . First the fork rod 13 is placed on the workpiece mounting frame 24, the end positioning device 211 is fixed on the workpiece mounting frame 24 and is located at one end of the fork rod 13, and the position of the fork rod 13 is initially positioned laterally by the end positioning device 211; The positioning device 212 is installed on the outside of the fork rod 13, and the width of the fork rod 13 is initially positioned by the width positioning device 212, and the approximate position of the fork rod 13 is limited by the preli...

Embodiment 3

[0030] see image 3 , image 3 It is a schematic diagram of the welding tooling structure of the outer fork parts. The workpiece mounting frame 24 is a rectangular frame structure, and four groups of symmetrical through holes are opened on both sides of the frame body, and the positions of the through holes are determined by the positions of the short shaft sleeves 12 . First the fork rod 13 is placed on the workpiece mounting frame 24, the end positioning device 211 is installed on the workpiece mounting frame 24 and is positioned at one end of the fork rod 13, and the position of the fork rod 13 is initially positioned laterally by the end positioning device 211; The positioning device 212 is installed on the inner side of the fork rod 13, and the width of the fork rod 13 is positioned by the width positioning device 212, and the approximate position of the fork rod 13 is limited by the preliminary lateral positioning and the preliminary width positioning. The outer fork p...

Abstract

The invention discloses an assembly welding tool of an inner and outer fork part in the field of welding tools. The inner and outer fork part is formed by welding two fork rods, two long shaft sleevesand 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. One long shaft sleeve penetrates the connecting holes in the heads of the two fork rods. The other 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 assembly welding tool comprises a workpiece mounting rack, a locating mechanism used for locating the fork rods, a jacking mechanism used for jacking the fork rods and a shaft sleeve fastening device used for fastening the long shaft sleeves and the short shaft sleeves, and the locating mechanism, the shaft sleeve fastening device and the jacking mechanism are all fixed to the workpiece mounting rack. All parts of an inner fork and an outer fork are assembled on the welding tool, the fixed point procedure is omitted, a both-way locating and jacking device is adopted, and the number of the locating mechanism and the jacking mechanism is reduced.

Description

technical field [0001] The invention relates to the field of pairing tooling, in particular to a pairing welding tooling for inner and outer fork parts. 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 butt-welding fixtures are point-setting fixtures and welding fixtures in a separate state, and the fixture positioning, jacking, and clamping mechanisms are still manually operated. There are many problems in th...
