DETAILED DESCRIPTION

[0032] The technical solutions will be described clearly and completely below in conjunction with the accompanying drawings of the embodiments of the present application.

[0033] First embodiment:

[0034] Please refer to Figure 1A kind of high-power electric polishing equipment of quick heat dissipation, including equipment body 1, the middle part of equipment body 1 is fixedly connected with motor 101, the output end of motor 101 is inserted with lifting drive shaft 102, the telescopic connection of lifting drive shaft 102 and motor 101 is realized by the way of insertion, and motor 101 can drive lifting drive shaft 102 to rotate, the bottom end of lifting drive shaft 102 is fixedly connected with grinding disc 103, the bottom of equipment body 1 is fixedly connected with feeding track module 104, and the workpiece on feeding track module 104 is polished by the descending grinding disc 103 of rotary motion, the outside both ends of motor 101 are fixedly connected with lifting cylinder 105, and the output end between two lifting cylinders 105 is fixedly connected with lifting support 106, and the middle part of lifting support 106 is rotatably connected with lifting drive shaft 102, lifting drive shaft 102 is adjusted by lifting cylinder 105 to drive lifting support 106, to realize the polishing contact and separation of grinding disc 103 and workpiece;

[0035] When polishing workpiece, the workpiece to be polished is placed on feeding track module 104 and is conveyed to the bottom of grinding disc 103, motor 101 drives lifting drive shaft 102 to rotate, so that grinding disc 103 rotates at high speed, then lifting cylinder 105 drives lifting support 106, so that lifting drive shaft 102 moves downward, grinding disc 103 contacts with workpiece, and workpiece is polished and polished, and subsequent grinding disc 103 rises, grinding disc 103 is separated from workpiece, and the polishing operation of workpiece is finished.

[0036] Please refer to Figures 2 to 5The outer part of the lifting driving shaft 102 is fixedly connected with a cold fan wheel 2. The lifting driving shaft 102 drives the rotation of the grinding disc 103, and simultaneously drives the cold fan wheel 2. The cold fan wheel 2 drives airflow to realize the air cooling and heat dissipation of the grinding disc 103. The outer part of the cold fan wheel 2 is sleeved with a cold air cover 201. The cold air cover 201 is fixedly connected with the lifting support 106. The lower opening of the cold air cover 201 is coincided with the grinding disc 103. The cold air cover 201 protects the cold fan wheel 2 and guides the cold air to blow to the grinding disc 103, so as to realize the air cooling and heat dissipation of the grinding disc 103. The left and right ends of the cold air cover 201 are fixedly connected with air ducts 202. The air ducts 202 are provided with windows 203 at the ends facing the grinding disc 103. The cold air is guided to pass over the edge of the grinding disc 103 through the air ducts 202, and is blown to the bottom of the grinding disc 103 through the windows 203, so that the cold air directly acts on the grinding part of the grinding disc 103, effectively improving the air cooling and heat dissipation effect of the grinding disc 103. The left and right ends of the feeding track module 104 are provided with telescopic grooves 204. The telescopic grooves 204 are fixedly connected with fixed plugs 205. The air ducts 202 are inserted into the telescopic grooves 204. The fixed plugs 205 are inserted into the air ducts 202. The movable range of the fixed plugs 205 is between the top end of the air duct 202 and the bottom end of the window 203. When the cold air cover 201 moves up and down with the grinding disc 103, the fixed plugs 205 move up and down in the air ducts 202, so as to realize the opening and closing adjustment of the windows 203.

[0037] When the grinding disc 103 is in the rising state, the air duct 202 is pulled up and separated from the telescopic groove 204. The fixed plug 205 in the telescopic groove 204 is lowered to the bottom end of the window 203, so that the cold air is blown out from the window 203 and directly acts on the bottom of the grinding disc 103, so as to realize the air cooling and heat dissipation of the grinding part of the grinding disc 103. The grinding disc 103 fully utilizes the time of grinding stop switching, and effectively improves the cooling efficiency of the grinding disc 103.

[0038] When the grinding disc 103 is in the descending state, the descending grinding disc 103 grinds and polishes the workpiece. The air duct 202 is lowered and inserted into the telescopic groove 204. The fixed plug 205 in the telescopic groove 204 is raised to the top end of the window 203, so that the air duct 202 is closed. The cold air in the cold air cover 201 is concentrated on the back of the grinding disc 103, so as to realize the air cooling and heat dissipation of the grinding disc 103 in the grinding and polishing state.

[0039] Please refer to Figure 6 and Figure 7The top surface of the fixing plug 205 is sloped, and the lower end of the slope of the fixing plug 205 is close to the window 203. After the cold air descending along the air duct 202 comes into contact with the top slope of the fixing plug 205, the direction of the cold air is changed, making it easier for the cold air to blow towards the bottom of the grinding disc 103. The fixing plug 205 is made of wear-resistant rubber material, which has strong wear resistance. A guide plate 206 is hinged to the bottom of the window 203. The guide plate 206 is inclined towards the bottom of the grinding disc 103. The cold air blown out of the window 203 The air is then guided upwards by the air guide plate 206, which facilitates the cold air to blow towards the bottom of the grinding disc 103. The air guide plate 206 is made of plastic sheet, which is lightweight and easy to move by the cold air. An elastic piece 207 is fixedly connected between the hinge end of the air guide plate 206 and the surface of the air duct 202. The elastic piece 207 is made of elastic rubber material. When the cold air blows on the air guide plate 206, it causes the air guide plate 206 to flip, adjusting the direction of the cold air in real time, which facilitates uniform air cooling at the bottom of the grinding disc 103.

[0040] When the grinding disc 103 is in the rising state, cold air is blown out from the window 203, and the cold air is oriented by the air guide plate 206. The blown cold air directly acts on the bottom of the grinding disc 103. During this process, the grinding disc 103 is in a high position and repeatedly rises and falls. The fixing plug 205 repeatedly rises and falls in the air duct 202, changing the air outlet height of the window 203. The cold air at different outlet heights is then guided obliquely upward by the air guide plate 206, so that the cold air swings back and forth to cool the bottom of the grinding disc 103, effectively improving the uniformity of heat dissipation at the bottom of the grinding disc 103.

[0041] Second implementation method:

[0042] Compared to the first embodiment, the main addition is a covering film ring 3, the specific addition structure is as follows, and the rest of the structure is the same as the first embodiment.

[0043] Please see Figures 8 to 11A covering membrane ring 3 is fixedly connected to the top of the lower opening of the cold air cover 201. The inner edge of the covering membrane ring 3 overlaps with the top edge of the grinding disc 103. The covering membrane ring 3 blocks the gap between the grinding disc 103 and the cold air cover 201, effectively reducing the leakage of cold air from the gap, thereby allowing more cold air to enter the air duct 202, indirectly enhancing the cooling effect of the cold air on the bottom of the grinding disc 103. Support feet 301 are evenly fixedly connected to the inner ring of the lower opening of the cold air cover 201. The support feet 301 contact the bottom of the covering membrane ring 3, providing support for the covering membrane ring 3 and effectively improving the wind resistance of the covering membrane ring 3. The support feet 301 and the cold air cover 201 are connected to the top of the lower opening of the cold air cover 201. A recessed groove 302 is provided at the top of the connecting end of 1. An ejector ring 303 is placed inside the recessed groove 302. The ejector ring 303 contacts the bottom of the cover diaphragm ring 3. The cover diaphragm ring 3 is made of rubber material. Both ends of the bottom of the ejector ring 303 are fixedly connected to the landing gear 304. The bottom end of the landing gear 304 contacts the upper edge of the telescopic groove 204. When the ejector ring 303 rises, it lifts the cover diaphragm ring 3, increasing the gap between the grinding disc 103 and the cold air cover 201, so that cold air can blow out from the gap (at this time, the air duct 202 has been sealed by the fixed plug 205). By enhancing the cold air circulation efficiency, the air cooling effect of the top and edge of the grinding disc 103 is effectively improved.

[0044] Compared to the first embodiment, when the grinding disc 103 descends for grinding and polishing, the cold air cover 201 descends along with the grinding disc 103, and the landing gear 304 lands on the upper edge of the telescopic groove 204, causing the ejector ring 303 to push the cover film ring 3 upward, causing the inner ring of the cover film ring 3 to flip and rise, lifting the inner ring of the cover film ring 3 to expose the gap between the grinding disc 103 and the cold air cover 201, so that cold air can blow out from the gap, effectively improving the cold air circulation efficiency and effectively improving the air cooling effect of the cold air on the top and edge of the grinding disc 103.

[0045] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
