Description
Technical Field
The invention relates to a method for processing automobile parts and components, in particular to a process for processing an automobile bearing cover by a production line.
Background
At present, most bearing caps in automobile reducer shells are machined in groups by using lathes or vertical milling machines, so that the clamping of parts is difficult, the machining precision is difficult to guarantee, the consistency of product sizes is poor, the operation is complex, the production efficiency is low, and the cost is high.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides the automobile bearing cover assembly line machining process which is convenient to machine and clamp, high in machining progress, good in product shape and size consistency, simple, convenient and safe to operate, high in production efficiency and low in cost.
In order to realize the purpose, the specific process method adopted by the invention comprises the following steps:
1. milling: an inner arc opening of a workpiece faces downwards, two points of a straight side face and an inner cavity arc side face and small planes below two ends of an outer arc are respectively used as an X-axis direction, a Y-axis direction and a Z-axis direction for positioning, the outer side of the workpiece is clamped by a pneumatic clamp, two lower planes at the arc opening are roughly and finely milled by adopting a plane milling cutter, and 4 milling tools are assembled in each group;
2. plane milling and drilling: using the milled two planes to perform Z-axis positioning, using one side surface to perform X-axis positioning, clamping two sides of a small plane on the bearing cover by using a special clamp, milling two small lug surfaces and a middle lug surface on the outer circular arc side surface of the bearing cover by using an end mill on a special clamp of a machining center, drilling bolt holes on two sides and chamfering;
3. tapping: and (4) tapping the middle lug thread by a machine, and manually removing burrs at the machined part.
By adopting the processing method, the invention has the advantages of high processing precision, good product size consistency, high processing qualification rate, simple and safe operation, low labor intensity of workers, convenient production management, high production efficiency and low cost, and has popularization and application values.
