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 auto parts, in particular to a processing technology for a transition swing arm of a steering device system of a heavy-duty vehicle. Including: milling the upper end face of the large ball head; milling the lower end face of the large ball head: drilling process positioning hole: boring process positioning hole; milling the small end face of the large and small taper hole; Holes and taper holes: Inner hole and taper holes at the lower end of the large ball head: Drilling and reaming Large and small taper holes: Milling threaded holes Plane: Drilling and tapping threaded holes. Each procedure of the technological process of the present invention is all processed on common machine tools, with less investment and quick efficiency increase. Mainly rely on the tooling to ensure the product requirements, the process arrangement is reasonable, it is convenient for workpiece positioning and clamping, the accuracy requirements of the workpiece can be guaranteed, and the processing 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...
