Description
Technical Field
[0001] The utility model relates to the technical field of numerically controlled machine tools, in particular to a numerically controlled gear grinding machine tool. Background Art
[0002] Gear is a common mechanical element used to transmit power and motion. It is composed of a disc or cylinder with multiple tooth grooves and usually meshes with other gears. CNC gear grinding machine is a gear processing machine that uses a grinding wheel as a grinding tool to process cylindrical gears or some gears, helical gears, and bevel gears. CNC gear grinding machine is mainly used to eliminate deformation after heat treatment and improve gear accuracy.
[0003] For example, the Chinese patent with announcement number CN220805744U discloses a CNC gear grinding machine, including a collection box and a back plate, wherein the collection box is fixedly provided with a back plate on one side, a slide groove is provided on one side of the collection box, a sliding seat is slidably provided in the slide groove, a positioning mechanism is provided on the sliding seat, a driving cylinder is fixedly provided on the sliding seat, a driving motor is provided on the driving cylinder, a grinding gear disk is connected to the output end of the driving motor, two connecting plates are fixedly and symmetrically provided on the back plate, a screw rod is rotatably provided between the two connecting plates, a forward and reverse motor is fixedly provided on one side of the connecting plate, and the output end of the forward and reverse motor is connected to the screw rod, a slider is threadedly connected on the screw rod, a gear mounting seat is rotatably provided at one end of the slider, and a dust suction mechanism is provided on one side of the collection box. The device has a good effect in collecting debris and dust, improves cleaning efficiency, reduces pollution to the environment, and reduces harm to the health of processing personnel.
[0004] Although the above example can collect the dust and debris generated during the grinding process by vacuuming, the grinding disc is exposed during the grinding process. The metal debris generated during the grinding process has too much gravity. The suction force generated by the vacuuming mechanism alone is difficult to overcome the impact force of the metal debris when it splashes at high speed. Therefore, the metal debris will still splash everywhere. At the same time, when there are a large number of gears to be ground, the processing method of only grinding one gear at a time has low processing efficiency and is inconvenient to use.
