Description
Technical field
The present invention relates to a kind of automatic clamping and device for discharging, particularly a kind of automatic clamping and device for discharging 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, allow the compressor enterprise time of having a rest significantly reduce, have to often work extra shifts or extra hours.
And make key components and parts---slide plate in the industry at compressor, the slide plate in the sliding-vane compressor is because the particularity of environment for use necessarily requires that it is wear-resisting, hardness is high, matrix precision height, appearance and size are strict.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 herein and are introduced.
Grind slide plate as can be seen and need a plurality of operations to cooperate to finish from the above slide plate flow process of respectively grinding, 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 states are 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, 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, slide plate is carried out the grinding of trace by abrasive pastes 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, 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, by 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 the control with lathe producer lathe sales volume 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 to 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, Machinery Tool Automation degree height, lathe can be finished the workpiece automated exchanged cutter automatically, automatically locate, automatic grinding, automatic on-line detects, automatic align hone error, automatically discharging, only need to arrange 1 operating personnel can finish 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 automatic clamping and device for discharging of Double End grinder.
Summary of the invention
