Abstract

The invention discloses an auxiliary tooling for the positioning welding of the front and rear semi-hanging tank seats and its use method, including a lifting saddle and a four-wheel saddle; the lifting saddle includes a support seat and a lifting mechanism, and is used for adjusting the height of the front tank seat during calibration ;The four-wheel saddle includes the base, the wheel assembly, the column and the upper end beam, which is used to support the rear tank seat during calibration; the method of use is the production of S01 lifting saddle and four-wheel saddle; S02 semi-trailer front and rear tank seat work site Horizontal calibration; S03 front and rear tank bases are hoisted in place as a whole; S04 tank body and tank base are paired. The advantage of the present invention is to ensure that the center plane of the tank body coincides with the center plane of the tank seat during the assembly process of the tank body and the tank seat; The positioning size is guaranteed when assembling tires and leaf springs on the assembly line, and the qualified rate of semi-trailer products is improved; the operation steps are simplified, the degree of automation is improved, the processing time is shortened, and the production cost is reduced.

Description

technical field

[0001] The invention belongs to the field of welding auxiliary tooling, in particular to an auxiliary tooling for positioning welding of front and rear half-hanging tank seats and a use method thereof. Background technique

[0002] At present, the production of the front and rear tank seats of domestic and foreign semi-trailers adopts simple tooling, that is, the C-shaped groove splicing group is used on the job site to assist in the formation of a horse stool. The production of semi-trailers is to control the height difference between the front and rear tank seats by hoisting the tank seat as a whole. On simple tooling, height difference adjustment is not performed. The disadvantage is that it is directly assembled and welded with the tank body, and the finished semi-trailer often flicks front and rear (the left and right error is more than 20mm), or it is biased to one side, or the leaf spring cannot be assembled normally after flowing into the next process...
