Description
Technical field
The present invention relates to a kind of grinder, particularly a kind of grinder that can grind synchronously the relative two sides of workpiece.
Background technology
As everyone knows, compressor is the heart of refrigeration plant, is requisite core component during air-conditioning is produced.China is the air-conditioning large market of selling in the world, it is predicted that the sales volume of annual air-conditioning will be about 3,500 ten thousand from now on.Domestic air conditioning market has been obtained brilliant achievement in the year in the previous year, certainly also driven the continuous prosperity in compressor of air conditioner market, in 2010, compressor of air conditioner enterprise is very busy great rejoicing, although produce busy, allow the compressor enterprise time of having a rest significantly reduce, have to often work extra shifts or extra hours.
And key components and parts---the slide plate in compressor making industry, it is wear-resisting, hardness is high, the matrix precision high, appearance and size is strict because the particularity of environment for use necessarily requires for the slide plate in the sliding-vane compressor.At this, we understand first the main grinding process of slide plate grinding:
Operation one: use face lapping mill to grind six planes of slide plate, see the above surplus of the monolateral reservation 0.02mm of light and both ends of the surface, the above surplus of the monolateral reservation 0.03mm in two sides is more than the monolateral reservation 0.06mm of two end faces.
Operation two: use the cylindrical lapping machine to carry out as benchmark with positive and negative in twos, corase grind R reserves the 0.06mm surplus in the bottom surface.
Operation three: use the vertical grinding machine with double end faces grinder, grind in twos the positive and negative controlling dimension at ± 0.001mm, parallelism of two planes 0.001mm.
Operation four: use face lapping mill with two positive and negatives as benchmark semifinishing two sides, perpendicularity guarantees in 0.005mm, monolateral reservation 0.015mm grind.
Operation five: use 3894 grinders to cooperate abrasive pastes simultaneous grinding both sides vertical plane, remove the emery wheel vestige and guarantee in the interior perpendicularity 0.004mm of fineness two sides scale error 0.002mm.
Operation six: use the cylindrical lapping machine with slide plate front and side as benchmark, correct grinding R face guarantees that dimensional accuracy is in ± 0.02mm.
Operation seven: reuse 3894 grinders and grind two sides, amount of grinding is that 0.5um is to deburring between the 1um.
Operation eight: the operations such as follow-up deburring, cleaning, check, constant temperature, classification, this follow-up operation and this project contact to omit not quite herein and introduce.
Can find out that from the above slide plate flow process of respectively grinding grinding slide plate needs a plurality of coordination of processes to finish, the operation of wherein grinding the slide plate two sides has reached more than 3 roads unexpectedly, and the milling time of two sides has restricted the whole production efficiency of slide plate greatly.And after grinding two sides, carry out again subsequent handling add trade union affect two survey the precision of faces, so desirable states are the last two survey faces that grind, avoid in the follow-up grinding of slide plate because the problems such as clamping or heating cause the two sides distortion, cause repeating grinding even scrapping of workpiece.
In addition, above-mentioned 3894 type grinders are that the reciprocal grinder of tailored version, its operation principle are for spreading upon by abrasive pastes on the very high abrasive material of two flatnesses and the depth of parallelism, slide plate is constantly moved back and forth in two parallel abrasive materials, by abrasive pastes slide plate is carried out the grinding of trace by it being advanced precompression, its amount of grinding can only lean on operating personnel by a large amount of practices it to be ground, be difficult for promoting so without the amount of grinding of standard operating personnel's level is had relatively high expectations, and this lathe operating efficiency is not high.For improving slide plate crudy and working (machining) efficiency, reduce the slide plate production cost, improve the functional reliability of compressor sliding blade, satisfying the market is to the great demand of slide plate, the applicant has developed a kind of efficient dual-end face grinder, it can process two and have the high and low parallel end faces of surface roughness of precision in one stroke, the Machinery Tool Automation degree is high, lathe can be finished the workpiece automated exchanged cutter automatically, automatically locate, automatic grinding, automatic on-line detects, the automaticrevisedhoning error, automatic discharging, only need to arrange 1 operating personnel can finish the operation of 10 above lathes, greatly saved personnel's input and reduced artificial operate miss.Greatly lower the human cost that slide plate grinds, and improved the qualification rate of product.
