Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings: the grinding wheel corrector includes a base 19, the lower screw 20 is installed inside the base 19, and two angular contact ball bearings III18 are used to fix the position with the end cover IV17, and the grinding end cover IV17 is in contact with the angle The contact surface of the ball bearing III18, adjust the axial clearance of the bearing to ensure that the axial movement of the lower screw 20 is less than 0.01mm, turn the lower screw 20 flexibly and without blocking phenomenon, install the lower nut 21 on the lower screw 20, Then install the middle slide plate 16 on the base 19, the middle slide plate 16 and the lower nut 21 are connected and fixed with bolts, the inclined iron I10 is installed between the middle slide plate 16 and the base 19, and they are ground together, and the gap is adjusted with the adjustment screw I8. Ensure the matching accuracy, and th...

The invention provides an abrasive wheel dresser which comprises a base and a motor, wherein two rollers are mounted in parallel on the shaft of the motor; a worm gear case is mounted on the base; a worm is mounted inside the worm gear case; the worm is meshed with a worm gear; the worm is fixed through an angle contact spherical bearing I, an end cover I and an end cover II; the worm gear is mounted on an upper screw rod; scales are formed in the worm; a hand wheel is arranged on the worm; a handle is arranged on the hand wheel; a lower screw rod is arranged inside the base; a lower screw nut is arranged on the lower screw rod; a middle sliding plate is arranged on the base; the middle sliding plate is fixedly connected with the lower screw nut through a bolt; a piece of inclined iron I is arranged between the base and the middle sliding plate; two upper sliding plates are arranged on the middle sliding plate; a piece of inclined iron II is arranged between the middle sliding plate and the upper sliding plate; two right-handed nuts and two left-handed nuts are respectively mounted inside holes of the two upper sliding plates; one end of the upper screw rod is crewed into the right-handed nuts and the left-handed nuts and is fixed through bolts. By adoption of the abrasive wheel dresser, the gap between the screw rods and the screw nuts can be effectively eliminated, the transmission precision is ensured, and the stability is ensured.
Description
technical field [0001] The invention belongs to the mechanical field, and in particular relates to a grinding wheel corrector. Background technique [0002] There are grooves on some mechanical parts, which need to be ground. The two sides of the used grinding wheel need to be corrected. The two rollers of the original corrector are respectively driven by two worm and worm gear pairs and driven by two lead screws, and are operated separately by two handwheels. The simultaneous movement of the two rollers cannot be realized, which may easily cause inconsistent corrections on both sides of the grinding wheel and asymmetry with the center of the workpiece. Each screw has only one nut, which makes it difficult to eliminate the gap between the screw and the nut, and easily causes correction errors. Contents of the invention [0003] The invention provides a grinding wheel corrector, which solves the disadvantage of correction error in the grinding wheel corrector in the backgro...
