Description
Technical field
The utility model relates to the servicing unit on a kind of non-standard equipment, specifically a kind of the friction type 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 utility model is not enough for prior art, and providing a kind of under just the sending out and turn of grinding machine, can utilize centrifugal force to clamp or unclamp the friction type automatic clamping chuck of workpiece.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of the friction type 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 collar relying on bearing to be connected, described second step is provided with the inner disc of several transverse holes of radial equipartition, the outer end of described transverse holes is provided with internal thread, friction column is disposed with in described transverse holes, spring and screw thread column cap, described friction column is against described second step, the front end radial equipartition of described thimble has 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 in described outer collar.
The low edge of described inner disc is provided with annular bead, described annular bead is provided with several briquettings, described briquetting is fixed in described outer collar.
The front end of described material folding plate is provided with the porose cover plate in center, and described cover plate is spun in described outer collar
The arranged outside of described bearing has capping, and described capping is arranged on described outer collar.
The utility model 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 collar and inner disc are when starting and brake, outer collar transmits strength from bearing, and inner disc transmits strength from friction post, and it is different for obtaining the strength that thimble passes over, so could realize the moment clamping of lathe rotating or unclamp workpiece, and replacement cost is low.
