Automatic loading and unloading cylindrical grinder of operation method
1. After startup, make it idle for 3-5 minutes, and then start to check whether each system works normally.
2. According to the workpiece to be processed to determine the specifications of the fixture, adjust the tightness of the fixture, so that it is convenient to clamp and reliable.
3. Adjust the machine tool: according to the shape and length of the workpiece, adjust the appropriate tailstock position, compress the tailstock, move the grinding wheel back a certain distance, install the workpiece, open the spindle, and make the workpiece rotate. Check whether it is convenient to take off the pin of the machine tool for normal contact with the spindle when it stops.
4. Dressing the grinding wheel: dressing the grinding wheel forming surface according to the workpiece drawing (special attention: before each repair, remember to retreat the grinding wheel first, retreat to the safe point where the diamond pen can be a certain distance after feeding, drive into the handle to make the grinding wheel close to the cutter holder, and then slowly shake the dial to let the grinding wheel contact the diamond pen slowly, and feed a small amount of feed for dressing)
5. Tool setting: install the workpiece, adjust the position of grinding wheel to make it align with the position of workpiece to be processed, and retreat the grinding wheel at a certain distance to ensure safety. Feed, slowly contact the workpiece for tool setting.
Automatic loading and unloading cylindrical grinder of main parts
1. The bed is the basic supporting part of the grinder. On it are equipped with grinding wheel frame 5, worktable 3, head frame 2, tailstock 7 and transverse sliding saddle, so as to keep the accurate relative position of these parts during working. The interior of the bed is used as an oil pool for hydraulic oil.
2. The head frame is used to install and hold the workpiece, and drive the workpiece to rotate. The head rest can rotate 90 ° clockwise in the horizontal plane.
3. The internal grinder is used to support the grinding wheel spindle for grinding the inner hole. The internal grinder spindle is driven by a separate motor.
4. The grinding wheel rack is used to support and drive the high-speed rotating grinding wheel spindle. The grinding wheel holder is installed on the sliding saddle 6. When grinding the short conical surface, the grinding wheel holder can be adjusted to a certain angle (± 30 ° in the horizontal plane).
5. The tailstock and the * of the head frame 2 support the workpiece together.
6. By turning the cross feed handwheel 9, the cross feed mechanism can drive the slide saddle 6 and the grinding wheel holder on the cross feed motion.
7. The worktable is composed of two layers. The upper table can rotate an angle (± 10 ° around the horizontal plane of the lower table) to grind the long circular cone with small taper. The head frame 2 and tail seat 7 are installed on the upper part of the upper table, which can make longitudinal reciprocating motion along the guide rail of the bed along with the working table.
