Abstract
An automatic gripping head apparatus of a meter lathe comprises a conical flexible gripping head embedded in the conical hole in front of the principal axis, pull tube connected at the rear of the conical flexible gripping head through screw and an electromagnet provided in the chassis, whose seat is fixed at the rear of the chassis. The electromagnet is of straight cylinder type. An armature is provided with through holes in the center, which is set in the pull tube via bearing movable sleeve together with the through holes and between the armature and the through holes, spring is provided. Through the action of the electromagnet, the armature pulls the pull tube, resulting in the conical flexible gripping head clamping. The apparatus has uniform strain force, fit for various conical flexible gripping head and it is characterized in convenient use and high working efficiency.
Description
Technical field
The present invention relates to turned part, particularly to the improvement of instrument lathe cartridge device.
Background technology
On instrument lathe, the chuck of holding workpiece adopts tapered collet, has at least three slits on the tapered collet, workpiece can be clamped when tightening.The syndeton of tapered collet on lathe as shown in Figure 1, be shaped on the conical surface on the tapered collet 1, main shaft 2 front ports of lathe are made taper hole, tapered collet 1 is embedded in this taper hole, the rear end of tapered collet 1 is provided with trombone slide 8, and by being threaded on the tapered collet 1, the tail end of trombone slide 8 is provided with awl dish 7, be arranged with pawl dish 5 and expanding sheath 4 on the main shaft 2, offer fork slot on the expanding sheath 4.During operation, by shift fork 3 is that illustrated left direction is stirred expanding sheath 4 backward, force the front end of the pawl 6 on the pawl dish 5 to open, because the back end in contact of pawl 6 is on awl dish 7, the conical surface of the contraction of rear end by awl dish 7 is to force resolution, awl dish 7 is retreated, promptly make trombone slide 8 retreat, the tapered collet 1 of trombone slide 8 pulling, by with the interaction of the taper hole of main shaft 2, make tapered collet 1 shrink clamping work pieces.
Owing to, realize clamping or loosening workpiece by the manual operation shift fork, can not work automatically, thereby inefficiency.
Summary of the invention
The object of the invention is to provide a kind of automatic clamping chuck device, to increase work efficiency.
The solution of the present invention is: a kind of automatic clamping chuck device of instrument lathe, comprise the tapered collet that is embedded in the front-end of spindle taper hole, the trombone slide that is connected tapered collet rear end, trombone slide and tapered collet are by being threaded, wherein, be provided with electromagnet in the cabinet, the pedestal of electromagnet is fixed on the rear end of cabinet, and armature is movably set on the trombone slide by bearing.
Electromagnet adopts straight barrel type, and the armature center is shaped on through hole, and armature is movably set on the trombone slide by bearing with this through hole.
Bearing between armature and trombone slide has fore bearing and rear bearing, and the outer ring of fore bearing fixedly is embedded in the armature inwall, and inner ring is movably set on the trombone slide; The inner ring fixed cover of rear bearing is located on the trombone slide, and the outer ring cooperates with the armature inwall is movable.
Be provided with spring between armature and trombone slide, the two ends of spring contact respectively on the fore bearing and rear bearing between armature and trombone slide.
Advantage of the present invention is: because the pedestal of electromagnet is fixed on the cabinet, armature is located on the trombone slide, and by the action of electromagnet, armature pulling trombone slide clamps tapered collet.In addition, the spring between armature and trombone slide has guaranteed the unanimity of tightening force size to be applicable to different tapered collets, has advantage easy to use, high efficiency.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Fig. 1 is the structure chart of existing instrument lathe cartridge device.
Fig. 2 is a structural representation of the present invention.
Mark among Fig. 1 and Fig. 2 is respectively: 1 tapered collet, 2 main shafts, 3 shift forks, 4 expanding sheaths, 5 pawl dishes, 6 pawls, 7 awl dishes, 8 trombone slides, 9 supports, 10 belt pulleys, 11 back-up rings, 12 armature, 13 fore bearings, 14 electromagnet pedestals, 15 back shrouds, 16 rear bearings, 17 springs, 18 main shaft bearings, 19 guide rails.
The specific embodiment
As shown in Figure 2, the automatic clamping chuck device of the instrument lathe of embodiment, comprise the tapered collet 1 that is embedded in main shaft 2 front end taper holes, the trombone slide 8 that is connected tapered collet 1 rear end, trombone slide 8 and tapered collet 1 are by being threaded, be provided with electromagnet in the cabinet 9, electromagnet adopts straight barrel type, and the pedestal 14 of electromagnet is fixed on the back shroud 15 of cabinet 9 rear ends, armature 12 centers are shaped on through hole, and armature 12 is movably set on the trombone slide 8 by bearing with this through hole.
The bearing that armature 12 and trombone slide are 8 has fore bearing 13 and rear bearing 16, and the outer ring of fore bearing 13 fixedly is embedded in armature 12 inwalls, and inner ring is movably set on the trombone slide 8; The inner ring fixed cover of rear bearing 16 is located on the trombone slide 8, and the outer ring cooperates with armature 12 inwalls are movable.
8 of armature 12 and trombone slides are provided with spring 17, and the two ends of spring 17 contact respectively on the fore bearing 13 and rear bearing 16 of 8 of armature 12 and trombone slides, and the front end of armature 12 is spacing with back-up ring 11.
Like this, 8 of armature 12 and trombone slides both can relatively rotate, and armature 12 can move axially in trombone slide 8 upper edges again.
Main shaft 2 is bearing in the support 9 with main shaft bearing 18, and main shaft 2 is provided with belt pulley 10, and motor drives main shaft 2 rotation works by belt.
When connecting electromagnet power supply, armature 12 is subjected to the electromagnetic force effect, be inhaled in the electromagnet pedestal 14, and the moving of armature 12, compression spring 17, and move after making trombone slide 8 by spring 17, spur tapered collet 1, make it to shrink clamping work pieces.
Behind the electromagnetic actuation, armature 12 is fixed, because armature 12 and 8 of trombone slides have bearing, trombone slide 8 can be driven by main shaft 2 and freely rotate.
When loosening workpiece, the tripping magnet power supply, armature 12 is released, and the pulling force of trombone slide 8 disappears, and tapered collet 1 is expanded under self elastic reaction, loosens workpiece.
The spring 17 that armature 12 and trombone slide are 8, be compressed when mounted, because the shift motion of armature 12 is greater than the stroke of trombone slide 8, can guarantee like this when the installation initial length that uses different tapered collets and chuck and trombone slide has deviation, the pulling force size is consistent, to guarantee the clamping effect of workpiece.
