Description
Technical field
This utility model relates to a kind of wheel dresser, particularly relates to the wheel dresser of a kind of vertical biplane grinding machine.
Background technology
Vertical paralleled surface grinding machine is generally used in precision plane processing, lower grinding wheel level before grinding, upper emery wheel is according to workpiece size and grinding allowance and lower grinding wheel at an angle, by two planes of the plane of upper and lower two panels emery wheel grinding work piece simultaneously in grinding process, upper and lower emery wheel does not all do feeding, but utilize the angle of wedge formed between grinding-wheel grinder bevel during two emery wheels installations, it is achieved the removal gradually to allowance.Emery wheel can produce the phenomenon such as particle detachment, granule blunt in grinding process, makes the workpiece surface quality ground reduce, and therefore, emery wheel is in use for some time, it is necessary to emery wheel is repaired, and makes emery wheel can recapture surface and sharp degree accurately.
Just because of this special grinding method of biplane grinding, the precision after workpiece grinding is had important impact by the pattern after crushing.And the pattern after crushing is closely related with the structure of crushing track and trimming device.
On current double-ended grinding machine, in trimming device, conditioning arm center of rotation is generally at the second quadrant position of emery wheel coordinate system, after emery wheel is trimmed, upper wheel face is concave surface, producing two kinds of harmful effects, one is that emery wheel sharp degree retentivity is not good, just needs to redress emery wheel after a small amount of workpiece of grinding；Two is dimensional accuracy and the surface accuracy that can affect workpiece after grinding, and then affects production cost and the efficiency of enterprise.
The trimming device of emery wheel generally uses manually or oil cylinder does power source, and manual trim is dangerous and inefficiency, and the stroke repairing the writing of indictments, appeals, etc. (diamond pen) is restricted, and single motion path is shorter, and finishing area is less than normal, and dressing efficiency is low.Do power source finishing with oil cylinder and need to increase a set of hydraulic pressure unit, increase floor space and high cost.It addition, the shaft system arrangement in current trimming device is unreasonable, cause that conditioning arm rigidity is not enough, bumpy motion, it is unfavorable for quick, the high accuracy finishing of emery wheel.
Summary of the invention
The purpose of this utility model is in that to provide the wheel dresser of a kind of vertical biplane grinding machine, to overcome disadvantages mentioned above.
For achieving the above object, technical solution of the present utility model is: the wheel dresser of a kind of vertical biplane grinding machine, including finishing seat, dresser shaft and conditioning arm, it is characterized in that: described finishing seat 9 is corresponding with the first quartile of emery wheel 1, it is provided with upper bearing (metal) 13 in this finishing seat, lower bearing 18 and dresser shaft 10, this dresser shaft is contained in upper bearing (metal) 13 and lower bearing 18, locking nut 11 is passed through in its upper end, upper press cover 12 and lower cover 15 axial locking, upper end cover 16 is passed through in lower end, bottom end cover 19 axial locking, the lower end of dresser shaft 10 is connected with motor 8 by reductor 7, the middle part of dresser shaft 10 is connected with conditioning arm 4 also by screw, one end of this conditioning arm is clamped with diamond pen 5.
Described upper bearing (metal) 13 is taper roll bearing, and lower bearing 18 is deep groove ball bearing.
Described motor 8 is servomotor.
The beneficial effects of the utility model are:
1, the change of conditioning arm center of rotation position, generally corresponding with the second quadrant position of emery wheel coordinate system (in Fig. 1 O of conditioning arm center of rotation (finishing seat) in trimming device1' place), now the emery wheel appearance after finishing is as it is shown on figure 3, upper grinding-wheel grinder bevel is inner concavity, at the workpiece grinding initial stage, the angle of wedge formed between grinding-wheel grinder bevel is less, becomes larger subsequently, feed-speed also gradually rises, and during final shaping, grinding condition is severe, is unfavorable for the lifting of workpiece accuracy.Conditioning arm center of the present invention is from the second quadrant position O of emery wheel coordinate system1' place is altered to the first quartile position O of emery wheel coordinate system1Position, now as shown in Figure 4, upper grinding-wheel grinder bevel is outer gibbosity to the emery wheel appearance after finishing, at the workpiece grinding initial stage, the angle of wedge formed between grinding-wheel grinder bevel is relatively big, tapers into subsequently, feed-speed also tapers into, and workpiece grinding condition progressively improves, and is conducive to improving machining accuracy.Additionally, due to the difference of the radius of gyration, emery wheel center line velocity is lower than the linear velocity of cylindrical, is distributed in grinding force suffered by the abrasive particle at emery wheel center more than grinding force suffered by the abrasive particle being distributed in cylindrical, thus grinding-wheel grinder bevel inter deterioration ratio is outside fast.The grinding-wheel grinder face shapes of evagination, is conducive to the maintenance of the effective pattern of grinding-wheel grinder bevel, can extend the retention time of crushing post-treatment precision, reduces the non-cutting time produced in production process because of crushing.
2, the change of power source: when driving conditioning arm that emery wheel is repaired, change of the prior art manual or hydraulic jack into motor to drive, maximum only 45 ° of original single its anglec of rotation of arc dressing track, and after using servomotor directly to drive, single arc dressing track (the abc track see in Fig. 1) is elongated, and its anglec of rotation can reach 90 °, both can improve dressing efficiency, save One hydraulic pump station simultaneously, reduce equipment cost and floor space.It addition, use motor direct-drive, intermediate transmission parts can be reduced, increase the reliability of transmission and the stability of conditioning arm.
3, the shafting structure connection and reasonable arrangement of trimming device, the layout of a pair taper roll bearing and a pair deep groove ball bearing makes conditioning arm axially and radially fix, and conditioning arm rigidity is big, stable movement during finishing.
