Abstract
The utility model relates to a novel feeding device for a bearing race external groove grinder, a feeding device of an original bearing race external groove grinder achieves actions such as the fast advance and retreat, the coarse fine grinding feed and the feed compensation by a hydraulic system, the mechanical structure is complex, the feeding accuracy is not high, and the manufacturing and the maintenance are difficult. The utility mode uses feed methods such as using a numerical control stepping motor to drive, a harmonic reducer to decelerate, a ball screw to locate and an oil pressure to track, two pairs of linear rolling guides are arranged, the utility model is a feeding device of the bearing race external groove grinder which has the advantages of simple structure, sensitive and reliable action, and high feeding precision.
Description
The utility model relates to a kind of bearing outer ring groove grinder feed arrangement
At present, the feed arrangement of known bearing outer ring groove grinder is to overlap very complicated mechanical, hydraulic feed system.The feed motion of workpiece is divided into fast feed, thick fine ginding feeding, no feeding grinding and withdraws from fast.During fast feed, pressure oil enters differential cylinder, and cylinder action drives the motion of the slide plate headstock, realizes fast feed.During thick fine ginding feeding, pressure oil enters the tooth bar oil cylinder, rotate by rack drives gear, feed screw, lobe plate, the rotation compression travel throttle valve control feed speed of lobe plate realizes the thick fine ginding feeding that control combines with control speed under the control effect.After thick fine ginding feeding finishes, do no feeding grinding by time relay time-delay.After the no feeding grinding of delaying time finished, oil cylinder oil return fast realized the fast return original position.Behind the trimming wheel, do feed compensation by the complicated compensation mechanism of a cover.Also need a cover static pressure oil supply system.
The purpose of this utility model provides a kind of simple in structure, reliable in action, the bearing outer ring groove grinder feed arrangement of high feed accuracy.
The purpose of this utility model is achieved in that stepper motor drives ball-screw by harmonic speed reducer, and slide can be moved forward and backward.The advance and retreat oil cylinder is fixed on the workbench, and oil cylinder piston is fixed on the bearing.During fast feed, the advance and retreat cylinder rod chamber is oil-filled, and after workbench was jumped 5 millimeters distances forward soon, collision block and block bumped against.At this moment owing to the self-locking action of harmonic speed reducer, workbench is in halted state.Electric subsequently travel switch works, and stepper motor begins swivel feeding, thereby makes slide begin to move forward; Simultaneously workbench is under the effect of rod chamber oil pressure, follow the tracks of slide march forward to, finish feed motions such as rapid advance, thick correct grinding.After grinding finished, the oil return of advance and retreat oil cylinder realized returning fast original position.Behind the trimming wheel, realize feed compensation by setting program control step motor.This feed mechanism has adopted the feeding method that the numerical control stepper motor drives, harmonic speed reducer slows down, ball-screw is located, oil pressure is followed the tracks of.Two pairs of linear rolling tracks are housed.Under the control of digital control system, only need a cover stepper motor, harmonic speed reducer, ball-screw group and an oil cylinder, just can finish fast feed, thick fine ginding feeding, no feeding grinding, withdraw from and whole feed motions such as feed compensation fast.
Owing to adopt such scheme, produced following beneficial effect:
1, the utility model is all selected high-accuracy actuated element for use, and ball-screw and linear rolling track all give application of load, and be very close to each other, so the transmission accuracy height can guarantee that machine tool feed is sensitive and accurate.
2, the utility model adopts digital control system controlling the feeding process, and is accurate, reliable, easy to adjust.
3, the more former feed arrangement of the utility model has omitted the complicated compensation mechanism of a cover, has reduced by three oil cylinders, has cancelled some complicated mechanical transmission mechanisms, and overall structure is simplified greatly.Because simple in structure, consumable accessory reduces, thus the fault rate reduction, for ease of maintenaince.
Introduce the utility model below in conjunction with accompanying drawing in detail by embodiment.
Fig. 1 is original feed arrangement structural representation.
Fig. 2 is original feed arrangement structural representation.
Fig. 3 is original feed arrangement structural representation.
Fig. 4 is this feed arrangement structural representation.
Fig. 5 is this feed arrangement structural representation.
As Fig. 4, Figure 5 shows that an embodiment of the present utility model.Stepper motor 1 drives ball-screw 3 by harmonic speed reducer 2, and slide 4 can be moved forward and backward.Advance and retreat oil cylinder 5 is fixed on the workbench 6, and oil cylinder piston 7 is fixed on the bearing 8.During fast feed, advance and retreat oil cylinder 5 rod chambers are oil-filled, and after workbench 6 was jumped 5 millimeters distances forward soon, collision block 9 and block 10 bumped against.At this moment owing to the self-locking action of harmonic speed reducer 2, workbench 6 is in halted state.Electric subsequently travel switch works, stepper motor 1 beginning swivel feeding, thus make slide 4 begin to move forward; Simultaneously workbench 6 is under the effect of rod chamber oil pressure, follow the tracks of slide 4 march forward to, finish feed motions such as rapid advance, thick correct grinding.After grinding finished, 5 oil returns of advance and retreat oil cylinder realized returning fast original position.Behind the trimming wheel, realize feed compensation by setting program control step motor 1.
