Abstract
The invention discloses an automatic differential chuck. A first step and a second step are arranged at the front end of a centre. The first step is provided with an outer ring disc connected through a bearing. The second step is provided with an inner disc connected through a friction ring. Three clamping plates heavier on the single sides are evenly distributed at the front end of the centre, the sides, facing the centre, of the clamping plates are arc clamping faces, rotating holes are formed in the clamping plates, the distances between the rotating holes and the two arc ends of the arc clamping faces are different, rotating shafts are installed in the rotating holes, and the rotating shafts are installed on the inner disc. The automatic differential chuck has the advantages that the centre clamping plates heavier on the single sides rotate around the rotating shafts through the centrifugal effect along with the forward and reverse rotation of a machine tool, and due to the fact that the distances between the rotating holes and the two arc ends of the arc clamping faces are different, the diameter of a tangent circle formed by the three arc clamping faces changes, when the diameter becomes large, a shaft type workpiece can be released, and when the diameter becomes small, the shaft type workpiece can be clamped.
Description
Technical field
The present invention relates to the servicing unit on a kind of non-standard equipment, specifically a kind of differential 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 a kind of outside being arranged on chuck, has the chuck of automatic clamping workpiece.
Summary of the invention
The present invention is directed to prior art deficiency, providing a kind of under just the sending out and turn of grinding machine, can utilize centrifugal force to clamp or unclamps the differential automatic clamping chuck of workpiece.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of differential automatic clamping chuck comprises a thimble be inserted on the heart carrier of lathe, the front end of described thimble is provided with first step and second step, described first step is provided with the outer ring dish relying on bearing to be connected, described second step is provided with the inner disc relying on drag ring to be connected, the front end of described thimble is evenly equipped with three one-sided material folding plates of laying particular stress on, the side towards thimble of described material folding plate is arc material folding face, described material folding plate is provided with rotating hole, the distance at the arc two ends in described rotating hole and described arc material folding face is inconsistent, rotating shaft is provided with in described rotating hole, described rotating shaft is arranged on described inner disc.
The outer edge of described material folding plate is provided with open slot, is provided with and stirs bar in described open slot, described bar of stirring is arranged on described outer ring dish.
The low edge of described inner disc is provided with annular bead, described annular bead is provided with several briquettings, described briquetting is fixed on described outer ring dish.
The front end of described material folding plate is provided with the porose cover plate in center, and described cover plate is spun on described outer ring dish.
The arranged outside of described bearing has capping, and described capping is arranged on described outer ring dish.
The present invention compared with prior art, there is following beneficial effect: 1) thimble is along with the rotating of lathe, one-sided material folding plate of laying particular stress under the action of the centrifugal, rotate around rotating shaft, because the distance at the arc two ends in rotating hole and arc material folding face is inconsistent, the diameter of a circle of cutting causing the formation in three arc material folding faces changes, when becoming large, can shaft-like workpiece be unclamped, when diminishing, can shaft-like workpiece be clamped; 2) outer ring dish and inner disc start and braking time, it is different for obtaining the strength that thimble passes over, so could moment of lathe rotating realize clamping or unclamping.
