Abstract
The utility model discloses digital control grinding machine for machining precise cylinder holes. The digital control grinding machine comprises a rack, wherein a working table, a control and programming system, a cutter shaft and a cutter arranged on the cutter shaft are arranged on the rack; the working table reciprocates on a guide track under the transmission of a driving device and a screw rod; a workpiece to be machined is clamped by a clamp on the working table; the working table is further provided with a pinch roller; the pinch roller is connected with a driving motor through a transmission wheel arranged on the pinch roller and through a transmission device; and the pinch roller is in rolling contact with the outer circumference of the workpiece to be machined. By utilizing the technical scheme, the problem that in the prior art, a precise cylinder cannot be machined for one time is solved effectively; and the problem that the geometric accuracy such as the straightness, taper and cylindricity of the machined hole in the prior art is large in fluctuation and low in pass percent is solved.
Description
Technical field:
The utility model relates to machining and uses lathe, is specifically related to a kind of numerically control grinder of processing precise cylindrical hole.
Background technology:
At present, machining enterprise is at the processing precise cylindrical hole, and for example it represents the plunger bushing endoporus in the part diesel injection pump; Hardness is 60-65HRC), the main precision index in this hole is: the main precision index that is finger-hole is: aperture size variation≤0.01mm, circularity≤0.001mm; Tapering≤0.005mm, cylindricity≤0.005mm, the axis verticality≤0.01mm in hole; Surface roughness≤the Ra0.08 in hole, the existing process technology of accurate cylindrical hole is time processing to guarantee, mostly prior art is to lean on manually-operated control; Not only labour intensity is big, and working (machining) efficiency is low, and each item machining accuracy index relies on workman's technical merit and experience fully and judges; Therefore quality fluctuation is big, aperture error is big, and the fluctuation of geometric accuracies such as the linearity in hole, tapering, cylindricity is big, and comprehensive qualified rate generally can only reach 30-50%.Under the certain situation of bottom outlet precision, reach the Accuracy of finish target, need to improve precision step by step through multiple operation processing, be difficult for realizing mechanization and automation.Will also bring pollution to environment simultaneously to workpiece cleaning between the operation, remaining abrasive material is difficult to clean, and workpiece will be used from now on bring hidden danger.
Summary of the invention:
The technical problem that the utility model will solve provides a kind of numerically control grinder of processing precise cylindrical hole; This technical scheme effectively solves the problem that prior art can't disposable processing when the processing precise cylindrical hole; And geometric accuracies such as linearity, tapering, the cylindricity fluctuation that has solved the prior art machining hole is big, the problem that qualification rate is low.
The utility model is realized through following technical scheme:
A kind of numerically control grinder of processing precise cylindrical hole; Comprise frame, the cutter that frame is provided with workbench, control and programing system, cutter shaft and is provided with, workbench is reciprocating on machine tool guideway through the transmission of drive unit and screw mandrel; In the anchor clamps of to be processed clamping on workbench; Also be provided with pinch roller on the said workbench, pinch roller is connected with drive motors through transmission device through the drive that which is provided with, and pinch roller rolls with to be processed cylindrical circumference and contacts.
The further Technological improvement plan of the utility model is:
Said anchor clamps are " V " type piece anchor clamps; Said cutter shaft is the high-speed electric expreess locomotive driving of 150,000 commentaries on classics through rotating speed; Described high-speed electric expreess locomotive is connected with frame through the bistrique seat.
The utility model advances more, and a step Technological improvement plan is:
Described drive unit is a motor, and transmission device is belt or is V belt.
The utility model compared with prior art has obvious advantage, and the utility model compared with prior art has the technological process weak point; Automaticity is high, and is simple to operate, and production efficiency is high; The 7-10 that is about conventional art doubly, the machining accuracy of this lathe is high, stable processing quality; Workpiece is easy to clean, and does not have remaining abrasive material to the injury in the part use, the processing comprehensive qualified rate >=and more than 90%.The utility model is that accurate cylindrical hole processing provides an effective process equipment, not only can be widely used in the processing of the similar precision component of mechanical industry, and the quality of promotion machining and the lifting of level are all had positive meaning.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
As shown in Figure 1; The utility model comprises frame 7; The cutter 22 that frame 7 is provided with workbench 1, control and programing system (not providing in the view), cutter shaft 21 and is provided with, workbench 1 is reciprocating on machine tool guideway 4 through the transmission of driving device motor 13 and screw mandrel 3, and screw mandrel 3 plays and drives that to be processed 5 F.F., worker advance, the effect of rewind down etc.; In the anchor clamps 11 of to be processed 5 clamping on workbench 1; Anchor clamps 11 are one " V " type piece, also are provided with pinch roller 12 on the workbench 1, and pinch roller 12 is connected with motor 13 through the transmission device belt through the drive 121 that which is provided with; Pinch roller 12 rolls with to be processed 5 cylindrical circumference and contacts, and can guarantee to be processed 5 cylindricity in the process of processing column hole like this; Cutter shaft 21 is high-speed electric expreess locomotive 2 drivings of 150,000 commentaries on classics through rotating speed, and high-speed electric expreess locomotive 2 is connected with frame 7 through bistrique seat 6.
In sum, the utility model can be realized goal of the invention.
