The positioning cylinder 16 is a double-acting cylinder, the tail part of the positioning cylinder is provided with an adjusting hand wheel 20, the adjusting hand wheel 20 drives an adjusting screw 21 to rotate on a cylinder seat 22, and the front end of the adjusting screw 21 is propped against a piston rod of the positioning cylinder 16.
The cylinder seat 22 is provided with a locking handle 23, and the locking handle 23 locks the position of the adjusting screw 21 after being closed.
Working principle: when the equipment leaves the factory, the manufacturer can set the reference position of the grinding wheel, and the specific operation is as follows: 1) Compressed air is introduced into the positioning cylinder 16 to drive the piston rod of the positioning cylinder to retract inwards, so that the positioning baffle moves backwards. When the piston rod of the positioning cylinder contacts with the adjusting screw 21, the positioning cylinder stops moving, and the position where the positioning baffle 17 stays is the grinding surface position of the grinding wheel and the reference position of the grinding wheel. 2) According to the grinding amount of glass, the adjusting hand wheel 20 is rotated to drive the adjusting screw rod 21 to move forwards and backwards, so that the specific position where the positioning cylinder stays when retracting backwards is controlled, and the position is the reference position of the working grinding wheel. 3) When the position of the positioning baffle reaches the set position, the locking handle 23 is pressed down to lock the position of the adjusting screw 21, so that the displacement of the adjusting screw 21 caused by the vibration of the machine tool in the later use process is avoided. 4) When the grinding wheel reference needs to be adjusted, the main cylinder is in an unlocking state. The main cylinder is filled with compressed air, and drives the sliding plate to move forwards, so that the grinding wheel on the motor moves forwards, and the main cylinder stops moving until the grinding surface of the grinding wheel is propped against the positioning baffle 17, so that the grinding wheel is in a reference position. 5) Locking the slide plate position requires locking the grinding wheel in this reference position. At this time, compressed air is introduced into the locking cylinder, and the piston drives the wedge block to move downwards and insert into the V-shaped groove. The wedge-shaped blocks are mutually extruded with the V-shaped grooves to push the left locking block and the right locking block to be outwards opened. The lower end of the locking block is hinged with the locking sleeve, so that the locking block can only swing outwards around a hinge point when moving outwards. At this time, under the action of the lever principle, the locking hole and the piston rod are mutually extruded, so that the Kong Yaosi piston rod is locked, the locking effect on the main cylinder is achieved, and the effect of locking the relative position between the sliding plate and the base is indirectly achieved. 6) After the reference position of the grinding wheel is locked, reverse air pressure is introduced into the positioning air cylinder 16, so that the positioning air cylinder drives the positioning baffle 17 to move outwards and leave the grinding wheel, and the grinding wheel is prevented from rubbing against the positioning baffle, so that the positioning baffle is damaged and the accuracy of next correction is prevented from being influenced. 7) When the grinding wheel is operated for a certain period of time, the grinding wheel wears, and the grinding surface of the grinding wheel is already lower than the reference, and the grinding wheel position needs to be corrected from new. At this point, the master cylinder needs to be released to adjust the grinding wheel position newly. When the locking device is adjusted, the air pressure of the locking air cylinder is released, the piston of the locking air cylinder is in a free moving state, and the elastic force generated by the reset spring pushes the piston upwards to reset the piston, and meanwhile, the wedge block is driven to move upwards to leave the V-shaped groove. When the locking block loses external driving force, the locking block naturally resets, so that the locking hole on the locking block is parallel to the cylindrical surface of the piston rod, and the piston rod can freely slide in the locking hole, thereby enabling the main cylinder to be in an unlocking state. At the same time, the positioning cylinder drives the positioning baffle to return to the reference position again. After the main cylinder is filled with compressed air, the main cylinder can be used for pushing the sliding plate to move forwards, so that the grinding wheel can feed forwards, and the worn part is compensated. When the grinding wheel contacts with the positioning baffle, the automatic correction of the grinding wheel reference can be realized, compressed air is introduced into the locking cylinder to lock the piston rod of the main cylinder again, and then the positioning baffle is reset.
Compared with the prior art, the structure in the scheme can realize quick and accurate correction of the reference position of the grinding wheel, so that the technical problem that the grinding wheel adjustment in the prior art needs professional personnel to operate is avoided while the production efficiency is greatly improved, and great convenience is brought to equipment users and the production cost is reduced. Meanwhile, the grinding wheel is accurate in reference, and the grinding wheel can work under the optimal load, so that the service life of the grinding wheel is prolonged, and the grinding wheel can be widely popularized and used.
