Abstract
The invention discloses a sealing surface grinding technology comprising the following steps of (1) preparing a grinding tool, (3.1) conducting coarse grinding and (3.2) conducting fine grinding. In the (3.1) step, the sealing surface has low roughness or 10-degree wedge angle has poor dying after check has to be coarsely grinded; a valve seat sealing surface can be pressed on the grinding tool or a piece of aluminum oxide abrasive cloth with pasting particle size of 80 to 100 mu; manual grinding or electric grinding can be conducted after a bit of diesel oil is added; in the (3.2) step, a fine grinding method is chosen for a grinded or fine-turned sealing surface according to concrete conditions of a part: a) dry grinding is employed via white corundum abrasive cloth with particle size of 120mu and a piece of metallograph abrasive paper is employed before dry grinding; (b) grinding agent is coated on a work surface of the grinding tool and manual grinding or a grinding machine is employed; the grinding agent is blended by W10 or W14 white corundum micro-powder grinding material and diesel oil; (c) a sealing member sealing surface can be manually grinded on a grinding panel; the grinding agent mentioned on the step (b) is applied on the panel; the surface of a work piece is applied to the panel and then rotate and move in a linear or 8-shaped way.
Description
Technical field
The present invention relates to a kind of sealing surface grinding technics.
Background technology
The adjustment in processing step and device parameter etc. of the existing sealing surface grinding technics there is also certain empirical and technical, for the operator newly started with, in addition it is also necessary to carry out substantial amounts of exercise and could grasp operation skill, produces the good product of quality.
Summary of the invention
In order to realize the purpose of the present invention, the present invention provides the sealing surface grinding technics of a kind of easy to operate, quick, easy left-hand seat.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of sealing surface grinding technics, including following operation:
1), lap tool
1.1) lapper material: generally select HT200～HT250, it is desired to even tissue, there is certain degree of hardness；
2), lap tool technology requires:
A) lap tool should through Ageing Treatment HB120～180 after roughing；
B) flatness of lap tool work surface and roughness can with grindings or grind to scrape and reach 0.04/ ф 600,1.6, and sealing surface of seat lap tool can grind after finish turning or develop and reach requirement；
C) lap tool needs regular reparation after using, and can determine as the case may be；
3), sealing surface Ginding process
3.1) rough lapping
All sealing surface roughness are low or 10 ° of angles of wedge need rough lapping through what dyeing inspection was worked poor, and sealing surface of seat can press or paste the aluminium oxide cloth that granularity is 80 order～100 orders on lap tool, adds a small amount of diesel oil and carries out hand lapping or electric grinding；
3.2) smooth grinding
Through the sealing surface of grinding or finish turning, select following smooth grinding method according to part concrete condition:
A) carry out dry grinding with granularity 120 whitish eye corundum cloth, carry out last dry grinding with abrasive paper for metallograph more if desired；
B) on lap tool work surface, coat grinding agent, adopt craft or grinder to be ground；Grinding agent is added diesel oil mediation by W10 or W14 white fused alumina micron power and forms；
C) closure seals face can carry out hand lapping on grinding flat plate；Flat board imposes grinding agent described in b bar, rotates after surface of the work and flat board laminating, while making straight line or figure of eight motion；During grinding, for preventing flat board abrasion inequality, grinding of constantly should shifting one's position on the surface of flat board.
The present invention is simple to operate, and operator's skill requirement is low, and product quality is high.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
A kind of sealing surface grinding technics, including following operation:
