Description
Technical field
The utility model relates to a kind of trimming device of repairing forming grinding wheel, especially can accurately repair the dresser of complex section shape.
Background technology
At present, the working method of the wheel dresser that uses in the production mainly contains two big classes: a class is to repair by the workman is manual, the workman leans against diamond pen on the fixing template emery wheel is repaired, this method is low to operator's requirement height, production efficiency, quality can't guarantee, and this method only is applicable to that finishing cuts the simple emery wheel of shape, is unfavorable for the production in enormous quantities of product.Another kind of is to utilize the trimming device with numerical control function to control diamond pen automatically to repair, the Buddha's warrior attendant nib is repaired emery wheel along the moving interpolation track, the theoretical foundation of this method be diamond pen with emery wheel between be always and contact, the Buddha's warrior attendant nib must be positioned at the normal orientation of grinding wheel section shape all the time, and wearing and tearing not only self are arranged in actual production during the diamond pen trimming wheel, and can not all be some contact all the time between diamond pen and the emery wheel, the Buddha's warrior attendant nib also can not be positioned at the normal orientation of grinding wheel section shape all the time, therefore repairs the grinding wheel section shape that comes out and has bigger error with theoretical section shape.Therefore this method is not suitable for the finishing section higher emery wheel of shape required precision.
The dresser of Chu Xianing (China Patent No. Z L 03231605.4) began to adopt diamond dressing wheel as dressing tool in recent years, and the feed mechanism of dresser adopts the X-Y numerical control table, NC table, and before comparing, the crushing precision is greatly improved.But when being connected with the diamond dressing wheel main shaft, adopts by the asynchronous machine of such dresser belt pulley mostly, this mode has following weak point: the one, and diamond dressing wheel needs rotation at a high speed during owing to trimming wheel, and the rotating speed of asynchronous machine does not far reach this requirement, this just requires the belt pulley connection to have very big speed increasing ratio, this makes pulley mechanism too fat to move, brings difficulty for the installation of whole dresser; The 2nd, because that asynchronous machine vibrates when rotated is bigger, make diamond dressing wheel also bigger in when finishing vibration, influence the crushing precision, can't accurately repair the emery wheel of complicated section shape.
Summary of the invention
Can not accurately repair complicated deficiency of cutting the shape emery wheel in order to overcome existing dresser, the utility model provides a kind of complicated high accuracy dresser that cuts the processing of shape emery wheel that is used for, this trimmer can not only be repaired the emery wheel that various complexity are cut shape, and cutting a shape precision and can reach higher level after the crushing, can satisfy the actual production requirement substantially.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of high accuracy dresser that is used for complicated section shape emery wheel processing, form by feed mechanism, diamond dressing wheel and diamond dressing wheel power source, its feed mechanism adopts the X-Y workbench, the diamond dressing wheel power source is electric main shaft, diamond dressing wheel is directly installed on the axle head of electric main shaft, and electric main shaft is fixedly mounted on the X-Y workbench.
Described X-Y workbench by the last planker of the following planker of base, directions X motion, the motion of Y direction, drive the motor drive mechanism that upper and lower planker moves and the guiding mechanism of upper and lower planker respectively and form; Motor drive mechanism is made up of servomotor, shaft coupling, ball wire bar pair and bearing, servomotor is by shaft coupling and ball wire bar pair direct connection, ball wire bar pair connects with last planker or following planker by ring flange, the one accurate thrust bearing of forming installing is housed sidewindering the ballscrew pair near servomotor one, adopt the fixed installation mode, away from servomotor one side one group of precise rolling bearing is housed, adopts the mounting means that moves about.
Described guiding mechanism by be installed in respectively planker, down between the planker and the double-slider rolling guide between following planker and the base form, two one group all is that center line is symmetrical arranged with the ball wire bar pair, preloading double-slider rolling guide in the employing.Slide block and upper plate and lower shoe connection place are provided with the adjustment pad, are used to regulate the depth of parallelism of planker Plane Installation.
During dresser work, two servomotors instruct according to control corresponding respectively and rotate, by the ball screw adjutant rotation motion of direct connection with it is rectilinear motion, and drive by the ring flange that connects with nut to go up planker and following planker moves on rolling guide, thereby the movement locus during formation diamond dressing wheel trimming wheel.Meanwhile, electric main shaft energising rotation at a high speed drives the diamond dressing wheel rotation, reaches accurately to repair the various complicated purposes of cutting the shape emery wheel that have.
An advantage of the present utility model is owing to adopted electric main shaft directly to drive the structure of diamond dressing wheel, can obtain the high rotation speed that needs, and compact conformation, vibrates very for a short time, has improved the dressing accuracy of emery wheel; Another advantage is the precise rolling bearing form that the motor drive mechanism of drive planker X, the motion of Y direction has adopted a hard-wired accurate thrust bearing of servomotor, ball wire bar pair and an end and an end to move about and install, improved the motion accuracy of planker on X, Y direction, thereby made this trimmer can accurately repair the various complicated emery wheels that cut shape that have.
