The headstock and tailstock are important parts of the cylindrical grinder, so when the two parts of the cylindrical grinder have problems, it is basically a big problem. At this time, how to adjust the headstock and tailstock of the cylindrical grinder is very important NS.
The headstock of the cylindrical grinder is composed of a headstock box and a headstock bottom plate. The headstock box can rotate around an axis on the headstock bottom plate, and the angle of rotation can be read from the scale plate. The headstock dial can realize stepless speed regulation through pulleys and frequency converters. The pre-tightening force of the triangle tape at one end of the motor is adjusted by the moving headstock motor.
The pre-tightening force of the V-ribbed belt on the headstock dial is adjusted by rotating the eccentric sleeve. When rotating the eccentric sleeve, the set screw must be loosened. After the eccentric sleeve is turned to the proper position, the set screw is tightened. The gap between the headstock spindle and the bearing is adjusted by rotating the scale sleeve. The scale sleeve rotates clockwise to increase the gap; otherwise, the gap decreases.
To adjust the tailstock of the cylindrical grinder, you need to turn the wrench to make the tailstock sleeve move back; you can also step on the footboard, which can make the tailstock sleeve automatically advance and retreat. If the foot is pressed to the bottom, the sleeve will move backward; if the foot is relaxed, the sleeve will move backward. go ahead. Or turn the adjustment knob to adjust the force of the pointed workpiece. When grinding a slender shaft, the force against the workpiece should not be too large, so as not to bend the workpiece.
When the main shaft needs to rotate, there must be a certain gap between the main shaft and the bearing, generally 0.005mm on the radius is appropriate. For the scale of the scale sleeve, one grid represents a gap of 0.001mm on the radius. When rotating the scale sleeve, the amount of idling of the scale sleeve must be removed. A three-jaw chuck can be installed on the headstock spindle for chuck grinding of short bushings or disc parts.
