Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] Such as Figure 1-5 A schematic diagram of the transition swing arm is given. Its processing process is:

[0037] (1) Mill the upper end surface 11 of the large ball head; use the lower end surface 14 of the large ball head and the outer diameter 1 of the large ball head as rough positioning, use the side surface 2 and the small end face 16 of the small tapered hole as auxiliary positioning, and use the moving platen tool to clamp, Machining on X5030 milling machine, using φ80 sleeve type face milling cutter, milling the upper end face 11 of the large ball head (see figure 1 and figure 2 );

[0038] (2) Milling the lower end surface 14 of the large ball head: the upper end surface 11 of the large ball head and the outer diameter 1 of the large ball head are used as positioning, and the side surface 2 and the large end surface 17 of the small...

Abstract

The invention relates to the technical field of accessories of automobiles, in particular to a process for machining transition swing arms of steering device systems of heavy-duty automobiles. The process includes milling upper end surfaces of large balls; milling lower end surfaces of the large balls; drilling auxiliary positioning holes; boring the auxiliary positioning holes; milling small end surfaces of large and small taper holes; milling large end surfaces of the large and small taper holes; lathing upper-end inner holes and taper holes of the large balls; lathing lower-end inner holes and taper holes of the large balls; drilling and reaming the large and small taper holes; milling planes of threaded holes; drilling and tapping the threaded holes. The process has the advantages that the transition swing arms are machined on various common machine tools in various working procedures of the process, accordingly, the investment is low, and the efficacy can be improved fast; requirements of products are mainly guaranteed by the aid of tools, the process is reasonable in arrangement, workpieces can be positioned and clamped conveniently, requirements on the precision of the workpieces can be guaranteed, and the machining efficiency is high.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a processing technology for a transition swing arm of a steering device system of a heavy-duty vehicle. Background technique [0002] Transition swing arm is a main product part of automobile steering system, which plays an important role in stable support and steering of wheels. And because the machining precision of the transition swing arm of the steering device is very high, for example, the coaxiality of the two holes is very strict, and the precision of the tapered hole is also very high. At present, the processing method of the transitional swing arm commonly used in the market is complicated to operate, the process arrangement is unreasonable, and the processed transitional swing arm is difficult to meet the technical precision requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing tech...
