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 auxiliary device on a kind of non-standard equipment, specifically a kind of differential automatic clamping chuck.
Background technology
There is a chuck, for folder when processing on cylindrical grinder or other machine components process equipment
Take workpiece, such as scroll chuck, heart carrier for bolt are first-class, be required for artificial gripping.
Non-standard equipment is used to replace artificial equipment, has minimizing labor intensity, the effect of lifting productivity effect, one
Operative employee can operate several equipment simultaneously, if workpiece also needs to artificial gripping one by one, then productivity effect is to carry
Do not rise.
The application have developed a kind of outside being arranged on chuck, has the chuck of automatic clamping workpiece.
Content of the invention
The present invention is directed to that prior art is not enough, provide a kind of can be under just the sending out and turn of grinding machine, using centrifugal force clamping or pine
Go into operation the differential automatic clamping chuck of part.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of differential automatic clamping chuck
Including a thimble being inserted on the heart carrier of lathe, the front end of described thimble is provided with first step and second step,
The outer ring disk that reliable bearing is connected is installed on described first step, described second step is installed reliable drag ring phase
Inner disc even, the front end of described thimble is evenly equipped with three unilateral material folding plates laid particular stress on, described material folding plate towards thimble
Side is arc material folding face, and described material folding plate is provided with rotating hole, described rotating hole and described arc material folding face
The distance at arc two ends is inconsistent, and described rotation in the hole is provided with rotary shaft, and described rotary shaft is arranged on described inner disc
On.
Open slot is provided with the described outer edge of material folding plate, is provided with described open slot and stirs bar, described
Stir bar to be arranged on described outer ring disk.
Annular bead is provided with the low edge of described inner disc, described annular bead is provided with several briquettings,
Described briquetting is fixed on described outer ring disk.
The front end of described material folding plate is provided with center the cover plate in hole, and described cover plate is spun on described outer ring disk.
The outside of described bearing is provided with capping, and described capping is arranged on described outer ring disk.
The present invention compared with prior art, has the advantages that 1) thimble, with the rotating of lathe, unilateral lays particular stress on
Material folding plate under the action of the centrifugal, rotate around rotary shaft, because the distance at the arc two ends in rotating hole and arc material folding face is not
Unanimously, the diameter of a circle of cutting causing the composition in three arc material folding faces changes, and when becoming big, can unclamp shaft-like workpiece, becomes
Hour, shaft-like workpiece can be clamped；2) outer ring disk and inner disc be in startup and braking, and obtaining the strength that thimble passes over is to differ
Sample, so the moment realization of ability lathe rotating clamps or unclamps.
