In order to meet the requirements, the following scheme is adopted to mount the main shaft on the moving bushing. The tail end of the shaft is a spline shaft, which can move relative to the spline bushing. The V-belt pulley is fixed by the flat key and the spline bushing. The spline bushing is tightly fitted to the unloading body by two rolling bearings. The advantage of this solution is that the axial movement of the main shaft can be realized, and the radial force belt pulling force acting on the main shaft of the belt transmission is eliminated, and the pulling force is applied to the unloading body. The bearing housing hole of the moving bushing is clamped once, and the machining precision and assembly precision are easy to ensure.
The design of the moving bushing is to fix a dial block on the moving bushing. The dial block is connected with the square nut through the pin shaft, the square nut and the screw rod form a transmission mechanism, and the hand wheel box body is fixed on the grinding head box body, and the hand wheel shaft in the box is fixed. The spiral gear is mounted on the inner end, and another helical gear meshed with the screw gear is fixed on the screw rod, and the screw shaft is rotated by rotating the hand wheel, and the square nut moves longitudinally along the screw rod, thereby driving the longitudinal movement of the sleeve. At the same time, an adjusting bolt is arranged at the bottom of the bottom of the grinding head box to adjust the swinging angle of the grinding wheel.
Motor base The left and right grinding heads of this machine are driven by one motor. The left motor base is fixed on the bed and the left turn body by screws, and the right motor base is fixed on the parent right turn body in the sliding city. Four bolts are welded to the base, and the motor is fixed on the bottom plate. The bottom plate is fixed to the bolt with a face washer and a nut, and the belt of the upper and lower grinding head can be adjusted by the nut to be tight. Lubrication system In order to keep all the friction surfaces in a state of lubrication, an oil cup is arranged in each of the upper left grinding head, the upper right grinding head and the lower right grinding head, and is shredded to each friction surface through a copper pipe, and the upper grinding oil cup is proposed for The upper and lower grinding heads move the bushings to lubricate, and the lower right grinding head oil cups provide lubrication of the sliding rails, the sliding screws and the nuts.
