Abstract

The invention discloses a clamping force controllable electric three-jaw chuck, and relates to the technical field of mechanical equipment. The clamping force controllable electric three-jaw chuck comprises a chuck main body, the inner surface of the chuck main body is in rotating fit with a toothed disc, and the inner surface of the chuck main body is in sliding fit with clamping jaws, toothed disc teeth are meshed with clamping jaw teeth, and the inner surface of the chuck main body is fixedly provided with a motor. A motor output shaft is fixedly provided with a bevel gear, bevel gear teethare meshed with the toothed disc teeth, a PLC controller is fixed on the inner surface of the chuck main body, a knob switch is fixed on the surface of the chuck main body, a button switch is fixed on the surface of the chuck main body, and a power supply box is fixed on the inner surface of the chuck main body. Pressure sensors are installed on the clamping jaws, the three-jaw chuck has functions of clamping force interception and control by means of the PLC controller matched with the knob switch and the button switch, the sensitivity and the practicality of the three-jaw chuck are improved, and the three-jaw chuck is convenient to use, has high safety and reduces the part damage probability.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to an electric three-jaw chuck with controllable clamping force. Background technique [0002] In the field of mechanical equipment processing, the three-jaw chuck is the most commonly used fixture. Whether it is a traditional lathe or a modern CNC lathe, the three-jaw chuck is an indispensable component. The three-jaw chuck consists of the chuck body , movable jaws and jaw driving mechanism. Under the guide part of the three claws on the three-jaw chuck, there are threads that mesh with the plane threads on the back of the bevel gear. When the small bevel gear is turned with a wrench through the square hole, the bevel gear rotates, and the plane threads on the back simultaneously Drive the three jaws to approach or withdraw from the center to clamp workpieces with different diameters. [0003] At present, no matter what kind of power source drives the existing three-...
