Abstract

The invention discloses a punch grinder, which comprises an eccentric shaft with an elongated front end. Two sides of the long side of the elongated strip are conical surfaces, and one end of the elongated strip is provided with a cylindrical protrusion. The eccentric shaft sequentially penetrates through shaft holes of a face plate, a dial, a rocker arm and a transverse moving controller. An indexing gear is peripherally mounted at the small end of the face plate, the face plate, the indexing gear and the dial are fixedly connected through bolts, the outer peripheries of the face plate, the indexing gear and the dial are a body, a rotary plate is mounted at the large end of the face plate, a straight flute is arranged on the rotary plate in the central diameter direction, and a V-shaped flute block is fixed to the front end of the rotary plate through bolts. The indexing gear of the punch grinder is matched with high-precision steel balls, rotation precision of 0.003mm circle run-out can be obtained, and part machining precision reaches +/-15' in angular cutting precision. The punch grinder is quite compact in structure and pretty convenient in adjustment.

Description

A kind of Punch formers

Technical field

The present invention relates to a kind of precision optical machinery device, be meant a kind of Punch formers especially.

Background technology

Generally when processing circle, ellipse, polyhedral part, usually adopt universal grinding machine external, surface grinding machine and dividing head to cooperate, but this processing method can't obtain higher running accuracy and angle segmentation precision, thereby influence the machining accuracy of part.

Summary of the invention

The problem that the present invention will solve is the deficiency that overcomes in the background technology; A kind of Punch formers is provided; This Punch formers adopts dividing gear to cooperate with high accuracy grade steel ball, can obtain round beating and reach the running accuracy of 0.003mm; The angle segmentation precision reaches ± 15 " part processing precision, this Punch formers structure is very compact, adjustment is very convenient.

For addressing the above problem, the present invention takes following technical scheme:

A kind of Punch formers of the present invention comprises eccentric shaft, and its front end is strip, and the both sides, long limit of strip are the conical surface, also has a cylindrical bump at an end of strip; Eccentric shaft penetrates in the axis hole of face, dial, rocking arm, horizontal mobile controller successively; The small end excircle of face is to being equipped with dividing gear, and face, dividing gear, dial link together through bolt; Excircle at face, dividing gear, dial is a body; The big distolateral rotary disk that is equipped with of face, the central diameter direction of rotary disk dovetail side is processed with straight trough, and vee-block is through being bolted to the front end of rotary disk; Its design feature is that said body cooperates through steel ball formation rolling with face, dividing gear, and face and rotary disk form through dovetail groove and be slidingly matched.

Further improvement project of the present invention is on the circumference between eccentric shaft and the dial spring to be installed, and the conical surface of inboard two conical surfaces of the straight trough of rotary disk dovetail side and eccentric shaft front end strip both sides matches.

Further improvement project of the present invention is that eccentric shaft adopts key to be connected with rocking arm.

Top one side that another further improvement project of the present invention is a body radially is equipped with cuts apart pin.

When operating Punch formers of the present invention, part is fixedly mounted in the vee-block, if need the angle of adjustment part, then pulls out and cuts apart pin; Directly rotate rocking arm, through the key transmission, drive eccentric shaft and rotate by rocking arm; Because of eccentric shaft under spring action, the long limit both sides conical surface of the strip of front end and the straight trough conical surface of rotary disk are fitted, and drive rotary disk with this eccentric shaft and make circular motion; Because of vee-block is fixed on the rotary disk, part is fixedly mounted in the vee-block, so finally realize the angle adjustment of part.If need the straight-line displacement value of adjustment part, also promptly adjust the straight-line displacement value of rotary disk, then will cut apart pin and push the dividing gear flank profil; Stop dividing gear and face to rotate, outside pulling transverse movement this moment controller promptly drives eccentric shaft and outwards moves, and makes both sides, the long limit conical surface of eccentric shaft front end strip break away from conical surface straight trough one segment distance on the rotary disk; But cylindrical bump also is arranged in straight trough; When rotating rocking arm, through the key transmission, drive eccentric shaft and rotate by rocking arm; This moment, rotary disk did not remake circular motion, and was moved as straight line through the dovetail groove of conical surface straight trough drive rotary disk along face by the cylindrical bump of eccentric shaft front end.

Take such scheme, have the following advantages:

Can find out by above scheme; Because forming to roll through steel ball with face, dividing gear, said body cooperates; Face and rotary disk form through dovetail groove and are slidingly matched; Beat and reach the running accuracy of 0.003mm thereby can obtain circle, and the angle segmentation precision reach ± 15 " part processing precision.

Owing on the circumference between eccentric shaft and the dial, spring is installed; The conical surface of inboard two conical surfaces of the straight trough of rotary disk dovetail side and eccentric shaft front end strip both sides matches; Therefore through horizontal mobile controller eccentric shaft can be moved forward and backward along axis; When the both sides, long limit of the eccentric shaft front end strip conical surface breaks away from conical surface straight trough one segment distance on the rotary disk, rotate rocking arm then rotary disk along the dovetail groove moving linearly of face; When eccentric shaft under spring action, when the long limit both sides conical surface of the strip of front end and the straight trough conical surface of rotary disk dovetail side are fitted, rotate rocking arm; Then rocking arm drives eccentric shaft; Eccentric shaft drives rotary disk again and rotates synchronously, forms circular motion, makes this Punch formers structure very compact.

Because eccentric shaft adopts key to be connected with rocking arm, can drive the eccentric shaft rotation when therefore rotating rocking arm again.

In addition, top one side of body radially is equipped with cuts apart pin, is used to control rotary disk and does that straight line moves or circular motion.When cutting apart pin and be pushed into the flank profil of dividing gear, then rotary disk is along the dovetail groove moving linearly, and when cutting apart pin and be drawn out the flank profil of dividing gear, then rotary disk and synchronous rocker are rotated and formed circular motion, so the adjustment of this Punch formers is very convenient.
