Description

Technical Field

[0001] The present invention relates to the technical field of grinding, and particularly relates to a gear grinding device with an adjustable grinding roller. Background Art

[0002] Grinding is a kind of surface modification technology. Generally, it refers to a processing method that uses rough objects to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. Grinding can be divided into manual grinding and mechanical grinding. Manual grinding refers to the method in which workers use hand-held grinding tools to grind workpieces. This method is suitable for small products or workpieces with complex shapes. The main tools include sandpaper, grindstones, and polishing paste, etc. When performing manual grinding, it is necessary to pay attention to maintaining a certain pressure and angle to ensure uniform grinding effect. Its advantages are flexible operation and precise control of details, but the efficiency is relatively low. Mechanical grinding is a method of grinding workpieces through mechanical equipment, which is suitable for mass production or processing occasions with high efficiency requirements. Common mechanical grinding equipment includes grinders, polishing machines, and grinding machines, etc. The advantage of mechanical grinding is that it can perform grinding quickly and efficiently, but it is relatively difficult to operate for workpieces with complex shapes.

[0003] In the prior art, during the production process of gears, it is often necessary to grind the sharp edges and corners generated during their processing. When gears are being ground, due to the different tooth space pitches of different gears, it is necessary to replace the formed grinding roller.

[0050] Working principle: Please refer toFigures 1 - 11 As shown, during use, the staff places the gear to be polished inside the workbench 1. Then, the staff uses multiple electric push rods 13 and a drive motor 17. When the drive shaft of the drive motor 17 rotates, it will drive the mounting roller 15 to rotate. Then, multiple first polishing sleeves 23 and multiple second polishing sleeves 24 on the surface of the mounting roller 15 will rotate together. Then, the telescopic rods of multiple electric push rods 13 will drive the mounting frame 4 and the mounting roller 15 to move and make them approach the gear inside the workbench 1. At this time, the formed polishing surfaces of multiple second polishing sleeves 24 and multiple first polishing sleeves 23 will polish the gear. When the polishing of a single tooth surface of the gear is completed, the telescopic rod of the electric push rod 13 will contract to drive the mounting frame 4 and the mounting roller 15 to reset.

Then, the two threaded bushings 33 will drive the two second mounting seats 32 and multiple groups of first polishing sleeves 23 and second polishing sleeves 24 on their surfaces to move away from or approach each other, thereby changing the distance between multiple first polishing sleeves 23 and multiple second polishing sleeves 24. In this way, it is convenient to adjust the use distance between multiple first polishing sleeves 23 and multiple second polishing sleeves 24, making it convenient to polish different types of gears.
