Description
Technical field
The utility model relates to a kind of work piece holder, particularly a kind of work piece holder that is used for the Double End grinder.
Background technology
As everyone knows, compressor is the heart of refrigeration plant, is requisite core component during air-conditioning is produced.China is the big market sold of air-conditioning in the world, it is predicted that the sales volume of annual air-conditioning will be about 3,500 ten thousand from now on.Brilliant achievement has been obtained in domestic air conditioning market 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, though produce busy; Let the compressor enterprise time of having a rest significantly reduce, have to often work extra shifts or extra hours.
And make the key components and parts---slide plate in the industry at compressor, 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 the main grinding process of slide plate grinding earlier:
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 vertical Double End 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 to be benchmark semifinishing two sides with two positive and negatives, perpendicularity guarantees in 0.005mm, monolateral reservation 0.015mm grind.
Operation five: use 3894 grinders to cooperate abrasive pastes to grind the both sides vertical plane simultaneously, 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 to be benchmark with slide plate front and side, 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: operations such as follow-up deburring, cleaning, check, constant temperature, classification, this follow-up operation and this project are got in touch to omit not quite here and are introduced.
Can find out that from the above slide plate flow process of respectively grinding grinding slide plate needs a plurality of operations to cooperate completion, 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 efficient of slide plate greatly.And after grinding two sides, carry out again subsequent handling add trade union influence two survey the precision of faces, so desirable state is the last two survey faces that grind, avoid in the follow-up grinding of slide plate because problems such as clamping or heating cause the two sides distortion, cause repeating grinding even scrapping of workpiece.And just present domestic processing method and production line of flow process probably can reach 200,000 slices/month production capacity.
In addition; The 3894 type grinders of more than mentioning are that the reciprocal grinder of tailored version, its operation principle are for spreading upon through 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; Slide plate is carried out the grinding of trace by abrasive pastes through it being advanced precompression; Its amount of grinding can only lean on operating personnel through a large amount of practices it to be ground, and the amount of grinding event of no standard is had relatively high expectations to operating personnel's level and is difficult for promoting, and this lathe operating efficiency is not high.Abroad compressor research starting country is early just measured to have to two of grinding slide plate and develop special-purpose grinder; Through with slide plate R bottom surface and both ends of the surface serving as the grinding datum level; Two measurements are ground simultaneously; As last procedure that grinds, the efficient of two survey faces is ground in just very big raising the two survey faces of grinding.But make the control of business opportunity bed sales volume with lathe because lathe assembling difficulty is directly proportional with working (machining) efficiency, the grinder of domestic as Japanese silver dollar company, the production of Korea S HBM company all is controlled at the working (machining) efficiency of 300,000 slices/month of a machine tool for the grinding efficiency of two sides.This working (machining) efficiency is still failed to satisfy on the market super large demand in batches for slide plate.For improving slide plate crudy and working (machining) efficiency; Reduce the slide plate production cost, improve the functional reliability of compressor sliding blade, satisfy the great demand of market slide plate; The applicant has developed a kind of grinder of Double End efficiently; 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, and lathe can be accomplished workpiece automated exchanged cutter, location, automatic grinding, automatic on-line detection, align hone error, discharging automatically automatically automatically automatically; Only need to arrange 1 operating personnel can accomplish 10 above operation of machine tool, saved personnel's input greatly and reduced artificial operate miss.Lower the human cost that slide plate grinds greatly, and improved the qualification rate of product.
For cooperating the Double End grinder to realize above-mentioned functions, the applicant has developed a kind of work piece holder that is used for the Double End grinder.
Summary of the invention
