Description
Technical field
The utility model relates to technical field of mechanical processing more particularly to a kind of electric chucks.
Background technique
Chuck type is divided into totally four kinds of oild chuck, air spider, common chuck and electric chuck now.Illustrate respectively:
Oild chuck needs to build hydraulic station, and sealing is perishable to be needed to adjust claw stroke at any time and need to be equipped with many claws, needs periodically
Hydraulic oil is replaced, working service is at high cost；Air spider needs air compressor machine, and being easy to appear gas leak phenomenon causes air pressure insufficient, makes
Safety accident at clamping workpiece shakiness to fall；Common gripper chuck holding force is unstable, and grasping force control is poor, to craftsmanship
And physical strength all has higher requirements, labor intensity of workers is higher, and processing efficiency is low for part.
Electric chuck has the advantages that high-efficient, use scope is wide, claw adjusting range is big when in use, and is not necessarily to gas
Pressure and hydraulic power supply, therefore have a wide range of applications.And the electric chuck drawback used on the market now is that chuck inner hole is straight
Diameter is small, and inner body is more, manufacturing cost is high, vibration is big when running at high speed.
Utility model content
In order to make up for the deficiencies of the prior art, the utility model provides a kind of electric chuck, can facilitate the clamping of workpiece
And reduce the inner body of chuck.
The utility model is achieved by the following technical solution: a kind of electric chuck, including chuck body, feature exist
In: the chuck body center is provided with through-hole, and there are four the sliding slots being equally spaced for setting in the chuck body, each
Claw is provided in the sliding slot, the side of each claw is provided with rack gear, and the rack gear is engaged with gear, described
Gear is fixedly connected with transmission shaft one end, and the transmission shaft other end is fixedly connected with sprocket wheel, and four sprocket wheels are connected by chain
It connects, the chain has also meshed with driving wheel, the output shaft of the driving wheel connection motor.
Ground is advanced optimized, the gear, the transmission shaft, the sprocket wheel and the chain are arranged at the chuck
Body interior.
Ground is advanced optimized, the claw width is consistent with the trough width.
Ground is advanced optimized, is provided with anti-skid chequer on the claw.
Ground is advanced optimized, the fixed dress for being fixed to chuck body on lathe is provided in the chuck body
It sets.
Ground is advanced optimized, the transmission shaft and the gear, the sprocket wheel weld.
Ground is advanced optimized, the motor is threephase asynchronous.
The beneficial effects of the utility model are:
Workpiece is placed into through-hole, control motor rotates forward, and drives driving wheel rotation, drives chain and four chain rotation
Dynamic, by transmission shaft, band moving gear is rotated, and is driven meshing gear movement, is moved synchronously four claws, labor cost is clamped, benefit
With the self-locking function of motor, workpiece is fixed；After the completion of work pieces process, motor reversal, the synchronous fortune of four claws are controlled
Row, unclamps the workpiece of clamping, can remove workpiece；
The utility model structure is simple, it is convenient to the clamping of workpiece and chuck inner body it is few, manufacturing cost is low, is worth pushing away
Extensively with application.
