[0002] Gears are mechanical components with teeth on their rims that can continuously mesh to transmit motion and power.

However, the gear workpieces in this grinding device are kept fixed by spring-pressed pressure rods. Due to the elastic deformation stroke of the springs, there is a problem of poor installation stability. Therefore, we propose a dressing grinding device for gear processing. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a dressing and grinding device for gear processing. Example

[0027] Combination Figure 1-7As shown, the present invention provides a gear processing dressing and grinding device, comprising: a grinding machine 100 and an installation assembly 200; the grinding machine 100 includes a control panel 101 and an electric slide rail 102 fixedly installed on both sides of its upper end, and a slide table 103 movably connected to the upper part of the electric slide rail 102; the installation assembly 200 includes a servo motor 201 fixedly installed on the slide table 103, an electric cylinder 202 fixedly installed at the front end of the servo motor 201, a fixing sleeve 203 fixedly installed at the outer end of the electric cylinder 202, an inner locking block 204 fixedly connected to the front end of the electric cylinder 202, an outer locking block 205 movably engaged at the front end of the inner locking block 204, a pressure plate 206 fixedly installed at the outer end of the outer locking block 205, a splined shaft 207 fixedly installed at the front end of the fixing sleeve 203, a gear component 208 movably installed at the outer end of the splined shaft 207, a keyway 209 opened in the gear component 208, and an outer mounting groove 210 opened in the pressure plate 206. The mounting sleeve 203 has an inner mounting groove 210 with multiple sets of external fixing posts 211 fixedly installed. An outer friction pad 212 is movably installed within the outer mounting groove 210. Multiple sets of external mounting holes 213 are arranged within the outer friction pad 212, and these holes 213 match the external fixing posts 211. The front end of the mounting sleeve 203 also has an inner mounting groove 214, within which multiple sets of inner fixing posts 215 are fixedly installed. An inner friction pad is movably installed within the inner mounting groove 214. 216, the inner friction pad 216 is also provided with a plurality of inner mounting holes 217, and the inner mounting holes 217 are matched with the inner fixing post 215. The upper end of the slide table 103 is also fixedly installed with a support arm 218. The inner end of the support arm 218 is also fixedly installed with a bearing 219, and the bearing 219 is movably installed on the outer end of the fixing sleeve 203. The side of the fixing sleeve 203 is also provided with a plurality of heat dissipation holes 220. The outer end of the fixing sleeve 203 is also fixedly installed with a protective cover 221.

[0028] Specifically, a gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. After the gear is manufactured, its rack and tooth groove may be deformed, so a grinding wheel grinder is needed to grind and polish the rack and tooth groove outside the gear. In this grinder 100, the inner locking block 204 installed at the front end of the electric cylinder 202 can be connected to the outer locking block 205 through a snap-fit ​​connection and pressed by the electric cylinder 202, so as to conveniently install and fix the gear component 208 to the fixing sleeve 203 and the pressure plate. Between 206, the installation and disassembly of gear component 208 before and after dressing and grinding are improved, and work efficiency is increased. Simultaneously, the external friction pads 212 and internal friction pads 216 installed on the inner ends of the pressure plate 206 and the fixing sleeve 203 can also be pressed against both ends of gear component 208 during clamping, thereby enhancing the friction during clamping and improving the stability of gear component 208 after clamping, thus preventing shaking during dressing and grinding. The splined shaft 207 at the front end of the fixing sleeve 203 mainly interacts with gear component 208. The keyway 209 at the inner end is matched and connected to avoid the rotation problem of the gear 208 during grinding. The outer mounting groove 210 and the inner mounting groove 214 are arranged and installed with outer fixing posts 211 and inner fixing posts 215, which mainly prevent the rotation problem of the gear 208 when the outer mounting groove 210 and the inner mounting groove 214 are pressed together, thereby improving the stability of the gear 208 after pressing. The support arm 218 and bearing 219 installed at the outer end of the fixed sleeve 203 are mainly used to move and support one end of the fixed sleeve 203 to ensure its good stability. The heat dissipation holes 220 arranged at the outer end of the fixed sleeve 203 are mainly used for heat dissipation of the electric cylinder 202 inside. The electric cylinder 202 is only used for single extension and retraction adjustment before and after fixing during operation, and it will not cause serious heat generation problems due to load operation. The protective cover 221 fixedly installed at the outer end of the fixed sleeve 203 is mainly used to protect the heat dissipation holes 220 to prevent liquid from entering the fixed sleeve 203.

[0029] Working principle and usage process of this utility model:

[0030] Before installing gear 208 for dressing and grinding, first activate the electric cylinder 202 inside the fixing sleeve 203 to move it forward. After the electric cylinder 202 moves forward, remove the outer locking block 205 at the outer end of the inner locking block 204. Then, pass gear 208 through the inner locking block 204 and engage it on the outer end of the splined shaft 207. After gear 208 is engaged on the outer end of the splined shaft 207, re-engage the outer locking block 205 at the outer end of the inner locking block 204. After the outer locking block 205 is installed, activate the electric cylinder 202 to move it inward, pulling the pressure plate 206 at the outer end of the outer locking block 205 to press gear 208. The gear 208 is pressed between the fixed sleeves 203 and the pressure plate 206 at both ends. At the same time, the inner friction pads 216 and the outer friction pads 212 installed in the fixed sleeves 203 and the pressure plate 206 can also be pressed between the two ends of the gear 208 during the pressing process to ensure the friction force during the pressing process and improve the stability of the pressing process, so as to carry out stable finishing and grinding work. After the gear 208 is finished and ground, the outer locking block 205 and the finished gear 208 can be removed in sequence by simply starting the electric cylinder 202 to move forward, thereby improving the convenience of disassembly and assembly and the stability of finishing and grinding.
