Technical field
The utility model relates to Machining Technology field, particularly relates to a kind of large gauge annular product inner hole grinding device.
Background technology
At present; the finishing of the annular product endoporus of large gauge is a difficult problem of field of machining always; especially the product of major diameter, large substance; inner hole precision requires higher (IT6-IT7); the method of finish turning is normally adopted to solve; often there will be the phenomenon of dimension overproof in process, dimensional tolerance and surface roughness are difficult to reach drawing requirement, and percent defective is higher.
In the prior art, CN201410388349.7 etc. have carried out some to electro spindle to be improved, but does not solve the problems such as equipment complexity, complex operation are low.
Therefore, this area needs to develop a kind of easy to use, grinding accuracy is high, percent defective is low large gauge annular product inner hole grinding device.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of easy to use, grinding accuracy is high, percent defective is low large gauge annular product inner hole grinding device.
In order to solve the problem, the utility model provides following technical scheme:
Utilize numerically controlled lathe to large gauge annular product inner hole grinding device, comprise the knife rest with locating slot and screw hole of numerically controlled lathe, a terminal pad coordinated with locating slot and the screw hole of knife rest is connected in knife rest lower end, terminal pad installs an emery wheel below by electro spindle, electro spindle is connected by ring flange with emery wheel, and electro spindle is fixedly connected with terminal pad.
Further improvement of the utility model is: conical surface axle is arranged in electro spindle lower end, the endoporus of described ring flange coordinates with conical surface axle, emery wheel is sleeved in the little journal axle of ring flange, and below ring flange, be provided with the platen compressing emery wheel, platen is connected with ring flange by bolt.
Further improvement of the utility model is: the lower end of conical surface axle is also provided with the gland be pressed on by ring flange on conical surface axle.
Further improvement of the utility model is: terminal pad is provided with the positioning boss coordinated with the locating slot on knife rest, and terminal pad and knife rest is fixed by 6 screws.
Further improvement of the utility model is: be arranged to eccentric structure by terminal pad between electro spindle and knife rest.
Owing to have employed technique scheme, the utility model achieves following technological progress:
The utility model installs electro spindle and emery wheel on numerically controlled lathe, Reforming of NC Lathe is become inner hole grinding machine, expand the range of work of numerically controlled lathe, when grinding major diameter ring parts, easy to use, grinding accuracy is high, percent defective is low, solve a grinding difficult problem for major diameter, large substance annular product endoporus, improve machining accuracy and the surface roughness of endoporus.And the utility model can require to select suitable electro spindle according to grinding, comprises power, rotating speed, frequency, diameter and length, realizes rotating speed adjustable by frequency conversion, improve grinding efficiency and precision further.The utility model improves terminal pad and electro spindle is become eccentric mounting structure with tool holder designs, and the shaft center line of electro spindle and the shaft center line of knife rest, not on same straight line, improve the utilization rate of emery wheel, increase the range of work of endoporus.
