Machining technology method of sealing surface

Abstract

The invention discloses a machining technology method of a sealing surface. The machining technology method is characterized in that a milling cutter is fed in the direction being vertical to the sealing surface of a machined piece from top to bottom with a circular machining trace diffusing from interior to exterior, and wave peaks and valleys alternately appear on the sealing surface, so that a zigzag structure is formed. The machining technology method of the sealing surface provided by the invention has the advantages that the machining speed is high, the abrasion of the cutter is small, the machining efficiency is high, the cost is lowered, wave peaks and valleys alternately appear on the sealing surface to form the zigzag structure, and a sealing contacting surface of the sealing surface is enlarged, so that a sealing effect is greatly improved.

Description

technical field [0001] The invention relates to the processing technology of the sealing surface of parts in the process of mechanical processing, and is especially suitable for the processing method of the oil inlet and outlet of the pump body of the automobile power steering and power vane pump. Background technique [0002] At present, the method of machining the sealing surface generally adopts the milling method. According to the different parts, most of them use tapered shank end mills. For different parts, different directions of lateral feed are used. Traditional processing methods such as figure 1 As shown, the feeding direction of the milling cutter 2 is to process the sealing surface of the workpiece 1 from left to right along the arrow. This processing method uses slow processing to improve the flatness and roughness of the surface to strengthen the surface sealing. Sex, but the efficiency is low and the milling cutter wears seriously. The better the surface rou...

[0002] At present, the method of machining the sealing surface generally adopts the milling method. According to the different parts, most of them use tapered shank end mills. For different parts, different directions of lateral feed are used. Traditional processing methods such as figure 1 As shown, the feed direction of the milling cutter 2 is to process the sealing surface of the workpiece 1 from left to right along the arrow. This processing method uses slow processing to improve the flatness and roughness of the surface to strengthen the surface sealing. Sexuality, but low efficiency, severe milling cutter wear

The better the surface roughness of the processing, the stronger the sealing performance. In order to achieve the purpose of good surface sealing, the processing speed must be reduced, which increases the cost virtually.
