Grinding wheel dressing device for worm grinding-wheel gear grinding machine

Abstract

The invention relates to a grinding wheel dressing device for a worm grinding-wheel gear grinding machine, which comprises first, second and third brackets, first and second high-speed motors, coarse and fine dressing diamond wheels, a worm grinding wheel, a worm grinding wheel installation seat, a driving servo motor, a grinding wheel installation shaft, a longitudinal servo motor, a longitudinal lead screw pair, a transverse lead screw pair and a transverse servo motor. The worm grinding wheel installation seat is fixed on a base; the worm grinding wheel is arranged at the inner end of the grinding wheel installation shaft; the grinding wheel installation shaft is sleeved in a bearing hole in the worm grinding wheel installation seat; the driving servo motor is arranged at the outer end of the grinding wheel installation shaft; the first bracket is arranged on the second bracket by the longitudinal lead screw pair; the second bracket is arranged on the third bracket by the transverse lead screw pair; one ends of lead screws of the transverse lead screw pair are connected with the transverse servo motor; one ends of lead screws of the longitudinal lead screw pair are connected with the longitudinal servo motor; and the first high-speed motor with the coarse dressing diamond wheel and the second high-speed motor with the fine dressing diamond wheel are respectively arranged at both sides of the first bracket.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and relates to a grinding wheel dressing device, in particular to a grinding wheel dressing device for a worm grinding wheel gear grinding machine. Background technique [0002] The worm grinding wheel gear grinding machine is a kind of equipment for finishing the gear. After the worm grinding wheel of the worm grinding wheel gear grinding machine has been used for a period of time, due to the shedding and wear of the abrasive grains of the grinding wheel, it is often necessary to modify the geometry of the grinding wheel. To restore its correct geometric profile, to ensure the accuracy of grinding teeth. At present, the worm grinding wheel dressing device in the prior art usually uses a diamond wheel for dressing, and for different gear modification parameters, it is necessary to replace the dressing diamond wheel with different machining accuracy. [0003] The worm grinding wheel dressing d...

AI Technical Summary

Problems solved by technology

The problem with the existing grinding wheel dressing mechanism is that the two diamond wheels respectively dress the left and right tooth profiles of the worm grinding wheel.

Therefore, only forming diamond wheels can be used for dressing. When the dressing parameters of the worm grinding wheel change, the corresponding diamond wheels must be replaced, which increases the dressing cost

At the same time, the worm grinding wheel is placed on a support that can move left and right when in use. Due to the heavy weight of the worm grinding wheel, in order to ensure the stability of the dressing process, the support that can move left and right must be reinforced, making the whole machine appear cumbersome; , the power mechanism that drives the left and right movable bracket must also have relatively large power, and the action of driving the relatively cumbersome movable left and right bracket also increases the energy consumption of the power mechanism
