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
The present invention relates to the process technology of part sealing surface in mechanical processing process, be particularly useful for the technological method for processing of the oil inlet and outlet of automobile assisted power steering power-assisted blade pump casing.
Background technology
At present, generally adopt the method for milling for the method for machining sealing surface, mostly adopt taper-shank end-milling cutter according to the difference of part, carry out the traverse feed of different directions for different parts, traditional processing method as shown in Figure 1, the feeding of milling cutter 2 is oppositely from left to right the sealing surface of workpiece 1 to be processed along arrow, and this kind of processing method is that flatness and the roughness of processing at a slow speed to improve face are strengthened face sealing, but efficiency is low, cutter wear is serious.The better sealing of plane roughness of processing is stronger, for reaching the object of good face sealing, must reduce process velocity, has increased virtually cost.
Summary of the invention
In order to overcome the problems referred to above of conventional seals method for processing surface existence, the invention provides the technological method for processing of the sealing surface that a kind of process velocity is fast, tool wear is little, working (machining) efficiency is high.
The technical scheme that the present invention adopted is for achieving the above object: the technological method for processing of sealing surface, and the direction of feed of milling cutter 2 is vertical from top to bottom with the sealing surface of workpiece 1, and cutter trade is the circle spreading from inside to outside.
On the sealing surface of described workpiece 1, form laciniation.
The technological method for processing of sealing surface of the present invention, process velocity is fast, tool wear is little, working (machining) efficiency is high, cost-saving, on sealing surface, form the phenomenon formation laciniation that Wave crest and wave trough alternately occurs, made the long-pending change of sealing contact surface of sealing surface large, thereby greatly strengthened sealing effectiveness.
Brief description of the drawings
Fig. 1 is the processing method schematic diagram of conventional seals face.
Fig. 2 is the processing method schematic diagram of sealing surface of the present invention.
Detailed description of the invention
The processing method of sealing surface of the present invention as shown in Figure 2, the direction of feed of milling cutter 2 is along the direction of arrow from top to bottom, the cutter trade that this processing mode forms is the circle spreading from inside to outside, after this vestige produces, on sealing surface, just form the phenomenon formation laciniation that Wave crest and wave trough alternately occurs, make long-pending the change greatly of sealing contact surface of sealing surface, thereby greatly strengthened sealing effectiveness.The method feature is that process velocity is fast, tool wear is little, retaining the good sealing property that improves working (machining) efficiency and sealing surface under original advantageous prerequisite, reaches cost-saving with this, raises the efficiency the object with product quality.
The present invention is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under instruction of the present invention, can modify to adapt to concrete situation and material and can not depart from the spirit and scope of the present invention these features and embodiment.Therefore, the present invention is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs to protection scope of the present invention.
Claims (2)
