Unnecessary loss；A kind of electric chuck with three jaws with self-protection function is provided.
In order to solve the above technical problems, structure of the invention includes disk body of chuck, three claws, and three claws are in positive three
Angular to be mounted on disk body of chuck, the position of corresponding three claws is equipped with three sliding rails on disk body of chuck, and claw is movably connected in
On sliding rail；Be additionally provided with Vidacare corp and self-protection device on disk body of chuck, three claws respectively with Vidacare corp
It is connected.
Further, the Vidacare corp includes electric cylinder, annular rack, gear and claw rack gear, annular rack
It is sleeved on the shaft of electric cylinder, each claw respectively corresponds a claw rack gear and a gear, and claw rack gear is arranged in card
The back side of pawl, claw rack and pinion are connected with annular rack and claw rack gear respectively, claw by the cooperation of rack-and-pinion with
Electric cylinder is connected.
Further: the self-protection device includes pneumatic linear actuator, shaft coupling and displacement sensor, and pneumatic linear actuator setting exists
The back side of disk body of chuck, shaft coupling are connected with the shaft of pneumatic linear actuator, and the inside of claw is equipped with groove, and displacement sensor is installed herein
In groove.
Further: radius dial is additionally provided on the disk body of chuck.
After adopting the above structure, the present invention can not only be driven by electric cylinder and is clamped automatically to workpiece, be improved
The working efficiency of chuck；And whether the design automatic detection workpiece to occur loosen and self-protection function if there is, prevents workpiece
It flies out in high-speed rotation process and peripheral devices and human body is damaged；And the present invention also has that structure is simple, is easy to make
It makes, energy conservation and environmental protection, practical and efficient advantage.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is positive structure schematic of the invention.
Fig. 2 is side structure schematic diagram of the invention.
Fig. 3 is the structural schematic diagram of Vidacare corp.
In figure: 1 is disk body of chuck, and 2 be claw, and 3 be sliding rail, and 4 be radius dial, and 5 be groove, and 6 be displacement sensor,
7 be pneumatic linear actuator, and 8 be shaft coupling, and 9 be electric cylinder, and 10 be annular rack, and 11 be gear, and 12 be claw rack gear
Specific embodiment
A kind of electric chuck with three jaws with self-protection function as depicted in figs. 1 and 2, structure includes disk body of chuck
1, three claws 2, three claws 2 are mounted on disk body of chuck 1 in equilateral triangle, the position of corresponding three claws 2 on disk body of chuck 1
Three sliding rails 3 are installed, claw 2 is movably connected on sliding rail 3；It is additionally provided with Vidacare corp on disk body of chuck 1 and self is protected
Protection unit, three claws 2 are connected with Vidacare corp respectively.The present invention drives three 2 edges of claw by Vidacare corp
Sliding rail 3 move, to be clamped using three claws 2 to workpiece；And it self is protected when just being processed using this design
Protection unit can detect the position of workpiece, check workpiece whether occur loosen, when workpiece occur loosen after self
Protective device just will start, and prevent workpiece from flying out during high speed rotation the environmental effects to surrounding.And this hair
It is bright by Vidacare corp instead of common manual driving device, improve the working efficiency of chuck.
Vidacare corp as shown in Figure 3 includes electric cylinder 9, annular rack 10, gear 11 and claw rack gear 12, annular
Rack gear 10 is sleeved on the shaft of electric cylinder 9, and each claw 2 respectively corresponds a claw rack gear 12 and a gear 11, claw
The back side of claw 2 is arranged in rack gear 12, and claw rack gear 12 is connected with annular rack 10 and claw rack gear 12 respectively with gear 11, card
