Description

Technical Field

[0001] The utility model relates to the field of gear grinding machines, and particularly relates to a gear grinding machine with flexible adjustment. Background Art

[0002] A gear grinding machine is a tool used to grind gears, thereby improving the aesthetics and use safety of the gear grinding machine. In order to improve the use convenience, a gear grinding machine with flexible adjustment is required. Among them, the "gear grinding machine with flexible adjustment" disclosed in the application number "CN202320797257.9" is also an increasingly mature technology. "For the gear grinding machine with flexible adjustment, by placing the gear disk on the backing plate, the area of the top end of the mounting column is larger than the area of the central hole of the gear disk. The mounting screw positions the gear disk through the gasket, and the mounting screw is tightened and fixed with the fixing screw hole. At this time, the mounting column and the gear disk are integrally arranged. The second adjustment motor can drive the gear disk to rotate through the mounting column, facilitating the adjustment of the contact position between the gear disk and the grinding wheel. The supporting tray plays a limiting role. Among them, the side profiles of the sliding groove and the sliding seat are both T-shaped. By sliding the sliding seat along the inside of the sliding groove, it is convenient to horizontally move the mounting box, thereby driving the backing plate and the gear disk to move. By passing the positioning bolt through the positioning block and the positioning port and fixing the bottom end with a nut, the backing plate can be positioned through the positioning plate, thereby positioning the mounting box, facilitating the adjustment of the positions of the mounting column and the backing plate according to the diameter of the gear disk, and the adjustment and use are more flexible and the applicability is better." However, during the use of this gear grinding machine, there are still the following defects: Although the gear grinding machine can indeed fix the gear through the structures such as the gasket, the mounting column, and the adjustment motor, these structures are relatively simple and can only install gears of a single thickness.
