Abstract

The invention provides a digital controlled cam grinder which comprises a digital control platform, a lathe bed, a working table, a grinding carriage etc., and the grinding carriage is fixed on the lathe bed; one side of a machine tool is provided with at least two grinding carriages which are respectively provided with a fine grinding head and a coarse grinding head; a lateral slipway is arranged under the working table, a vertical guide rail patched with the working table is arranged above the working table, the lower part of the working table is patched with the lathe bed by a lateral guide rail; two servo motors are respectively connected with the working table and the lateral slipway by a screw rod, the vertical and lateral movements of the two servo motors are driven and controlled by an operating floor. The invention greatly improves the working efficiency and assures that the feeding size and angle of the quality of workpieces are finished by the self body of digital controlled grinder, and less human factors lead the quality of the products to improve and the pollution is reduced; the processing of the digital controlled grinder is realized only by means of x and y axial rails, and the digital cam controlled grinder has the advantages of simple structure, convenient operation, good stability, low add noises and low price etc.

Description

A kind of numerically-controlled cam grinder

Technical field

The invention belongs to mechanical manufacturing field, be specifically related to a kind of numerically-controlled cam grinder

Background technology

At present, China adopts homemade imitative type method or manually grinds processing work, and what the quality of workpiece was all leaned on is that artificial working experience is controlled the emery wheel of rotation at a high speed or the feeding size and the angle of control workpiece guarantees; When workpiece was irregular curved surface, it made complicated, and pollution is big, the cycle is long, at the bottom of the efficient, not only can not in time meet the need of market, and labor strength is big; The cam that special picture processes with imitative type method because its synchronism and low precision, directly causes the noise of weaving loom big, vibrations are big, rotating speed is low, also affect the quality and the output of fabric product simultaneously; Another traditional problem is: the emery wheel that a kind of model only is housed on machine, in the time must considering allowance and efficient simultaneously, often to adopt two machines that the different grain size emery wheel is housed respectively to realize simultaneously, promptly on same machine, can't solve efficient simultaneously with two problems of surface accuracy; And when adopting two machinings, produce error owing to resetting, product percent of pass is descended greatly.

Summary of the invention

The object of the present invention is to provide a kind of numerically-controlled cam grinder, it has not only realized No. one time clamping on same machine, finish roughing to accurately machined whole process, and realize maintenance and compensation to the feeding size and the angle of bistrique by digital control system and axial trajectory, simple in structure, and the precision height.

Technical scheme of the present invention is: a kind of numerically-controlled cam grinder, comprise numerical control platform, lathe bed, workbench, grinding carriage etc., lathe one side is furnished with two grinding carriages adorning correct grinding head and roughing heads respectively at least, grinding carriage is fixed on the lathe bed, and divide into a horizontal slide unit at described workbench, which is provided with the longitudinal rail that connects with workbench, and it connects by cross slide way and lathe bed down, two servomotors, and can drive, control it and make vertical and horizontal respectively and move with workbench, laterally slide unit is connected by screw mandrel.

Link to each other by reduction box between the flatness that be to keep bistrique, main axle servo motor output shaft and main shaft.

And the servomotor output shaft can be by synchronizing wheel with band or shaft coupling be connected with screw mandrel synchronously.

Further improvement of the present invention is: be provided with the emery wheel stand between grinding carriage and the lathe bed, be equipped with rectilinear orbit on the described emery wheel stand, grinding carriage is fixed in track and can adjusts the position in orbit.

The present invention is because in practice, reduced the machine operation pilot process, make the defect rate of workpiece be reduced 90%, improved production efficiency greatly, and the feeding size and the angle that guarantee workpiece quality all are finishing by numerically control grinder itself, less human factor makes the quality of product be greatly enhanced, and less pollution; Advantages such as the processing of this numerically control grinder only realizes by means of X, Y two axial tracks, and is simple in structure, easy to operate, and this grinding machine also has good stability, and it is low to add noise, and price is low.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.

As Fig. 1, shown in 2, a kind of numerically-controlled cam grinder, comprise the numerical control platform, lathe bed 15, workbench 14, grinding carriage 1 etc., two grinding carriages 1 of correct grinding 2 and roughing heads 3 are housed respectively on the cross track 11 of the emery wheel stand 17 of lathe one side, grinding carriage 1 is fixed on the emery wheel stand 17 by alignment pin, and can adjust the position of grinding carriage as required in orbit, the emery wheel stand is fixed on the lathe, relative with the emery wheel stand thirty years of age of workbench, and described workbench is arranged with a horizontal slide unit, slide unit is provided with the longitudinal rail that connects with workbench, and it connects by cross slide way and lathe bed down, two servomotors by screw mandrel respectively with workbench, laterally slide unit connects, and can drive, control it and do the vertical and horizontal motion respectively, link to each other by reduction box between main axle servo motor output shaft and the main shaft on the workbench and be located at, cam workpiece is equipped with in the main shaft outside, and is on the same straight line with the bistrique axle center; Between servomotor output shaft and the screw mandrel by synchronizing wheel with band or shaft coupling are connected synchronously.

Transmit data in servomotor at grinding machine work hours control platform by computer, servomotor drives screw mandrel and rotates according to transmitting data, and the control slide unit is or/and the displacement feeding amount of workbench, and can be as required, realize No. one time clamping, finish roughing to accurately machined whole process.
