Problems solved by technology

[0003] 1. In this traditional meshing process, the wear of the grinding wheel is very serious, especially at the tooth root, because the grinding amount is the largest, and the grinding position corresponding to the grinding wheel has a high working intensity. Long-term work is easy to cause the wear of the grinding wheel and increase the gear. The cumulative error between;
[0004] 2. The processing of a gear is often completed by the same grinding wheel, which also leads to very low production efficiency;
[0005] 3. Unilateral grinding can easily deform and twist gear shaft workpieces, seriously affecting the processing size and accuracy;
[0006] 4. On the gear shaft, when the distance between the two gears to be processed is very close, when processing the small gear, due to the interference of the large gear, the worm grinding wheel gear grinding machine cannot complete the processing operation, and the place close to the large gear exists The processing blind area seriously limits the processing range of the equipment

Embodiment 1

[0037] A high-precision gear grinding machine, comprising a frame 1, on which a workbench 3 for installing a workpiece 2 is arranged, and one end of the workbench 3 is provided with a clamping motor A4 controlled by a pulse and a driving motor 5 with a workpiece The workpiece clamping slide 6, the clamping motor A4 drives the workpiece clamping slide 6 to perform axial reciprocating motion and axial vibration of the workpiece. The reciprocating motion refers to that the workpiece moves back and forth on the workbench 3, because the grinding wheel does not move in the axial direction of the workpiece in the embodiment, and relies on the axial movement of the workpiece itself to meet the requirements of the processing position; the axial vibration refers to the pulse control, so the The above-mentioned pulse is preferably an ultrasonic pulse, so that the workpiece undergoes microscopic reciprocating vibration to realize the main grinding process of the workpiece. The core of the ...

Embodiment 2

[0047] This embodiment is basically the same as Embodiment 1, the difference is that three groups of grinding mechanisms are arranged symmetrically on the center of the frame 1, and the angle formed between every two processing points and the axis of the workpiece is 120°. The structures of the three groups of grinding mechanisms are exactly the same, and their grinding amounts are different, which are used for rough, semi-finishing and finishing. Symmetrical processing is convenient to reduce the deformation of the gear shaft, reduce the frequency of grinding wheel grinding, improve the stability of the workpiece, and increase the processing accuracy. At the same time, different grinding amounts can increase the processing efficiency of the workpiece. The three sets of grinding mechanisms are 5-10 times that of traditional equipment, and their service life is 10-20 times that of traditional equipment. Grading processing helps to reduce inter-tooth errors and increase the mach...

Abstract

The invention belongs to the technical field of gear machining equipment, in particular to a high-precision gear grinding machine. The machine comprises a rack, a workbench for installing a workpieceis arranged on the rack, a clamping motor A and a workpiece clamping sliding table which are controlled by pulses are arranged at one end of the workbench, and the clamping motor A drives the workpiece clamping sliding table to conduct axial reciprocating motion and axial vibration of the workpiece; one or more sets of grinding mechanisms are arranged on the rack and comprise grinding wheel bases,the grinding wheel bases are provided with grinding wheel feeding mechanisms and grinding wheel sliding tables, and the grinding wheel feeding mechanisms drive the grinding wheel sliding tables to conduct feeding motion perpendicular to the workpiece axis; grinding wheels are arranged at the front ends of the grinding wheel sliding tables, and grinding wheel driving motors which drive the grinding wheels to rotate are arranged at the back ends of the grinding wheel sliding tables. According to the core of the high-precision gear grinding machine, main grinding and machining of the workpiece are achieved through reciprocating vibration, sub grinding and machining of the workpiece are achieved through meshed motion of the grinding wheels and the workpiece, and accordingly the wear degree ofthe grinding wheels is lowered. In addition, the contact area during vibration is large, the grinding speed is extremely high, and the precision is also greatly improved.
