Method for firstly processing support seat with an X-shaped frame and secondly welding

Abstract

The invention provides a method for firstly processing a support seat with an X-shaped frame and secondly welding, which is characterized by comprising the following steps of: firstly processing the support seat with an X-shaped frame; and then welding a walking frame main body, wherein when the walking frame main body is welded, the welding order is noticed, and the welding line of the symmetric position is simultaneously welded by two persons so as to reduce welding deformation and satisfy the flatness requirement on the installation of a rotary support. The invention has the advantages of easy and safe operation, increased efficiency and saved equipment. In the invention, support seats of all diggers can be firstly processed and secondly welded.

Description

technical field [0001] The invention relates to a processing method for a main body of an excavator walking frame. Background technique [0002] Such as Figure 1 to Figure 3 Shown is a schematic diagram of the excavator walking frame. The main body of the walking frame consists of the middle and front ribs 1, the middle and rear ribs 2, the rear right ribs 3, the front right ribs 4, the rear left ribs 5, the front left ribs 6, the oil pool ring 7, the joint mounting plate 8, Lower cover plate 9, ring 10, upper cover plate 11, support ring 12, X frame support seat 13 and circular plate 14 are welded. [0003] In order to meet the flatness requirements for installing the slewing support, the main body of the walking frame needs to be processed after welding. Due to the welding deformation of the main body of the walking frame, the traditional process method is to weld the main body of the walking frame first and then process it, which can meet the flatness requirements of ...

AI Technical Summary

Problems solved by technology

Due to the welding deformation of the main body of the walking frame, the traditional process method is to weld the main body of the walking frame first and then process it, which can meet the flatness requirements of the slewing support installation. However, due to the large volume of the main body of the walking frame after welding, the equipment required for post-welding processing The tooling and tooling are very large, and the clamping and processing time is long, which not only affects the efficiency of mass production, but also has certain difficulties in the post-welding processing of the X-frame of large excavators.
