1. When the equipment is stopped for more than eight hours, the machine should be hydraulically lubricated for 5-10 minutes, then manually operate each moving shaft to check whether the operation of each part is normal; confirm that the operation is normal, the lubrication is good, and there is no alarm. start working.
2. It is forbidden to open the electric control cabinet without permission.
3. The operator must be familiar with the structural performance of the device, the transmission principle and the processing application. After obtaining the operation certificate, the operator can operate independently.
4, the operator must conscientiously do "three good" (management, use, repair) "four sessions" (will use, will maintain, will check, will eliminate the fault).
5. The operator must abide by the “five disciplines” of using the equipment and the “four requirements” of the maintenance equipment.
6. The operator should check the equipment at any time according to the requirements of “Rolling Inspection Contents”.
7, in strict accordance with the equipment oil requirements for refueling, to achieve lubrication "five fixed" (timed, fixed point, quantitative, qualitative, fixed).
8. It is forbidden to carry out trial operation and prohibit shifting during processing.
9. During the work, the sound is prevented from being mixed into the drip system to prevent the waste such as cotton yarn from falling into the machine.
10. It is strictly forbidden to move or damage the warning signs on the machine.
1. There are two commonly used methods at present:
One uses two synchronous motors to respectively drive the grinding wheel spindle and the workpiece spindle, and replaces them with a hanging wheel; a numerical control method is to install a pulse generator on the grinding wheel spindle to emit a pulse proportional to the rotation of the spindle, and the pulse is controlled by a numerical control. After the system is modulated, the workpiece spindle is driven by the servo system and the servo motor, and the feedback signal generator is mounted on the workpiece spindle.
2, indexing grinding: This type of grinding machine can be divided into butterfly wheel type, large plane grinding wheel type and conical grinding wheel type according to the shape of the grinding wheel. They all use the principle of meshing of rack and pinion, and use a grinding wheel instead of a rack to grind the gear. The tooth profile of the rack is straight and the shape is simple, which is easy to ensure the dressing precision of the grinding wheel. The gear is rolled on the imaginary rack during machining. Each time the roll is reciprocated, one or two tooth faces are ground. Therefore, multiple divisions are required to grind the entire tooth surface.
Continuous grinding: the grinding machine for continuous grinding, the grinding wheel is worm-shaped, called the worm grinding wheel grinding machine, the grinding wheel is equivalent to the hob, and the workpiece is made into a moving motion, and the involute is ground. The workpiece is axially reciprocated to grind the teeth of the spur gear, and if it is tilted, the helical gear can be ground. The grinding wheel has a high rotational speed, and the developed chain cannot be mechanically connected to the grinding wheel and the workpiece.
