Abstract

The invention discloses a fixed type automatic chuck. The fixed type automatic chuck comprises an ejector pin, wherein the ejector pin is inserted in a heart-shaped chuck of a machine tool; a step is arranged at the front end of the ejector pin; a fixing plate sleeves the step and is connected with the step by a square key; an outer ferrule sleeves the outer side of the fixing plate and is connected with the outer side of the fixing plate by a bearing; three irregular clamping plates of which one sides are heavy are distributed at the front of the fixing plate in the radial direction; one side, which faces the center, of each clamping plate is an arc-shaped clamping surface; a rotary center hole is formed in the other side, which is close to the corresponding arc-shaped clamping surface, of each clamping plate; distances from the rotary center hole of each clamping plate to two ends of the corresponding arc-shaped clamping surface of the clamping plate are different; and a rotating shaft which is fixed on the fixing plate is arranged in each rotary center hole. The fixed type automatic chuck has the advantages that the rotating shafts rotate forwards and reversely along with the ejector pin and drive the clamping plates to rotate, one sides of the clamping plates are heavy, the center of gravity of each clamping plate is different from the center of gravity of the corresponding rotating shaft, so that the clamping plates deflect, the diameter of a tangent circle formed by the three arc-shaped clamping surfaces can be increased or reduced, and a workpiece can be clamped or released; and an opening groove and a pull sliding rod have a guiding effect.

Description

A kind of fixed automatic clamping chuck
Technical field
The present invention relates to the servicing unit on a kind of non-standard equipment, specifically a kind of fixed automatic clamping chuck.
Background technology
Cylindrical grinder or other machine components process equipment there is a chuck, is used for the gripping workpiece when processing, as first-class in scroll chuck, heart carrier for bolt, all need artificial in gripping.
Non-standard equipment is used to replace artificial equipment, has minimizing labour intensity, and promote the effect of productivity effect, an operative employee can operate several equipment simultaneously, if workpiece also needs artificial gripping one by one, so productivity effect does not promote.
The application have developed the outside of a kind of equipment at chuck, has the chuck of automatic clamping workpiece.
Summary of the invention
The present invention is directed to prior art deficiency, provide a kind of can substitute artificial, can automatic clamping part to be processed and the fixed automatic clamping chuck automatically unclamping the part machined when lathe rotating.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of fixed automatic clamping chuck comprises a thimble be inserted on the heart carrier of lathe, the front end of described thimble is provided with step, on described step, cover has fixed disk and is connected with square key, the outside cover of described fixed disk has outer collar and is connected with bearing, the front of described fixed disk is radially distributed with three one-sided irregular material folding plates of laying particular stress on, described side, material folding Ban Chao center is arc material folding face, described side, arc material folding face is provided with a rotation center hold, the distance at the two ends in described rotation center hold and described arc material folding face is inconsistent, a rotating shaft be fixed on described fixed disk is provided with in described rotation center hold.
The edge, base of described fixed disk and the upper edge of described outer collar are provided with an annular protrusion, and described bearing is clipped between the annular protrusion described in two.
The outer side edges of described material folding plate along on be provided with open slot, be provided with one in described open slot and be fixed on described outer collar pulls out slide bar.
The front of described material folding plate is provided with the porose cover plate in a center, and described cover plate is spun on the front end of described outer collar.
Described thimble is taper, and described tailstock barrel has a shrouding being connected and fixed dish and outer collar.
The present invention compared with prior art, there is following beneficial effect: 1) rotating shaft is along with thimble rotating, material folding plate is driven to rotate, material folding plate is one-sided lays particular stress on, center of gravity and rotating shaft inconsistent, material folding plate is deflected, and the diameter of a circle of cutting that the arc material folding face described in three is formed can become large or diminish, to clamp or to unclamp workpiece; 2) open slot with pull out slide bar and play guide effect.
