Description
Technical field:
The present invention relates to a kind of multitool processing valve numerical control double-slider unit head.Mainly be the machining of processing pump valve flange, the valve that the present invention is fit to processing has: gate valve, stop valve, check-valves, butterfly valve, pressure-reducing valve etc. have the valve body piece of flange.
Background technology:
Present domestic pump valve manufacturing enterprise adopts engine lathe usually to the processing of valve part, vertical lathe, the simple nc machine of Digit Control Machine Tool or the transformation of the way of common universal machine is processed valve flange, but Digit Control Machine Tool also has limitation, mainly be that valve body blank dimension and sprue gate height difference are very big, programming brings great difficulty to Digit Control Machine Tool, these lathes are clamped in valve body blank flange one end on the machine chuck when the processing valve body, drive workpiece by chuck and rotate the turning flange, the tune clamping cutting other end after finishing, two end flanges machine in the back processing flange need chuck fixedly special fixture come the clamping valve body, the processing of head flange causes the clamping poor rigidity in carrying out.The shortcoming of valve body conventional machining process is:
(1) workman's clamping workpiece on lathe is consuming time, and potential safety hazard is arranged, and need drive a vehicle or the tailstock auxiliary clamping as the heavy caliber valve body, also needs centering to clamp.
(2) traditional handicraft is to rotate to be principal cutting movement with workpiece, and the very big workpiece rotary speed that causes of centrifugal force is slow, and influences the stability of piece-holder, and needing tailstock to withstand valve body sometimes could process.
(3) each procedure of traditional handicraft all will carry out clamping and correction with valve body, certainly will influence workpiece precision, labor strength, safety like this, reduces production efficiency and product percent of pass.
Need repeatedly feeding just can finish processing when (4) cutting.Pump valve flange turning processing need have multiple operation such as cylindrical, end face, chamfering, endoporus, waterline groove to finish, and the engine lathe knife rest generally can only once mounting four cutter, cause the thick smart cutter of a lot of situations to share one, influence cutter life, and influence the flange surface quality.
Summary of the invention:
The present invention is between the deficiency of above-mentioned traditional pump valve processing technology, a kind of numerical control double-slider multitool processing dynamics head that provides, and purpose is to improve the clamping technology of workpiece and repeatedly cut the feeding problem.This unit head is to adopt the boring processing technology, cutter rotates to realize principal cutting movement, so but the workpiece clamping is processed at stationary fixture, if can realizing a clamping multiaspect, processes this unit head configuration lathe general utility functions parts NC rotary table.Manufacturing procedure is concentrated, reduced the clamping workpiece number of times, not only can shorten non-cutting time, and be easy to guarantee each surperficial relative positional accuracy of processing in the once mounting.This unit head facing head has disposed double-slider and multitool clamp structure knife rest, make multitool participation cutting in the cutting at one time feeding process, turning can have 6 cuttves to cut simultaneously, and the cutting end face can have 4 cuttves to cut simultaneously and waterline groove and inside and outside circle chamfering can both reach fast and finish; The slide block of this facing head and knife rest all are balanced configurations in addition, make principal cutting movement reach dynamic equilibrium state.Adopt multiple cut can solve repeatedly feeding problem, can improve crudy again, because the valve body manufacturing procedure should be divided into roughing and fine finishining usually, the roughing chipping allowance is big, cutting force is also big, and heat in metal cutting is also higher, after the roughing because internal stress redistribution, make workpiece deformation bigger, thus after the roughing again fine finishining can make workpiece obtain higher precision and roughness.
