The temperature and duration of sintering directly affect the final production quality and service life of the ceramic grinding wheel.
[0003] Currently, sintering is commonly carried out in electrically heated furnace chambers. However, existing sintering devices only have two heating surfaces, which leads to uneven heating inside the furnace and uneven heating of the workpiece, thus affecting product quality. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a sintering device for ceramic grinding wheel processing, which has the advantage of uniform workpiece heating and avoids the problem of uneven workpiece heating.

It also includes: The top of the furnace body is fitted with a cover plate, and a servo motor is fixedly connected to the top of the cover plate. A rotating shaft is fixedly connected to the output end of the servo motor. Multiple sets of L-shaped columns are fixedly connected to the side wall of the rotating shaft. Gears are rotatably connected to the bottom of the L-shaped columns. An internal gear ring is fixedly connected to the bottom of the cover plate, and the gear and the internal gear ring are meshed. A connecting column is fixedly connected to the bottom of the gear. Multiple sets of placement plates are fixedly connected to the side wall of the connecting column. A connecting plate is fitted to the bottom of the placement plate. Multiple sets of limiting columns are fixedly connected to the top of the connecting plate.

[0006] According to some embodiments, a temperature controller is fixedly connected to the side wall of the furnace body, and the temperature controller is fixedly connected to the heating rod. A protective atmosphere pipe and a cooling gas pipe are fixedly connected to the bottom of the side wall of the furnace body, and the protective atmosphere pipe is located above the cooling gas pipe.

Beneficial effects
[0008] This utility model provides a sintering device for ceramic grinding wheel processing, which has the following beneficial effects: (1) The sintering device for ceramic grinding wheel processing places the placement plate in the inner cavity of the furnace and heats the workpiece with heating rods. At the same time, the servo motor drives the gear to rotate through the rotating shaft and L-shaped column. Since the gear and the internal gear ring are meshed, the gear can drive the connecting column to rotate.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Reference Figures 1-4 A sintering apparatus for ceramic grinding wheel processing includes a main board 1, a furnace body 101 fixedly connected to the top of the main board 1, and multiple sets of heating rods 102 fixedly connected to the inner wall of the furnace body 101. It also includes: A cover plate 2 is snapped onto the top of the furnace body 101. A servo motor 201 is fixedly connected to the top of the cover plate 2. A rotating shaft 202 is fixedly connected to the output end of the servo motor 201. Multiple sets of L-shaped columns are fixedly connected to the side wall of the rotating shaft 202. A gear 203 is rotatably connected to the bottom end of the L-shaped column. An internal gear ring 204 is fixedly connected to the bottom of the cover plate 2. The gear 203 and the internal gear ring 204 are meshed. A connecting column 205 is fixedly connected to the bottom of the gear 203. Multiple sets of placement trays 206 are fixedly connected to the side wall of the connecting column 205. The bottom of the placement tray 206 is snapped with a connecting tray 207. The top of the connecting tray 207 is fixedly connected with multiple sets of limiting posts 208. The limiting posts 208 penetrate the placement tray 206 and are distributed on the side of the placement tray 206. The side wall of the limiting posts 208 is threaded with nuts. It should be noted that: the workpiece is placed on the surface of the placement tray 206, and then the limiting post 208 on the top of the connecting tray 207 is inserted into the placement tray 206 and fixed with a nut. At this time, the limiting post 208 restricts the workpiece on the surface of the placement tray 206. Then, the cover plate 2 is used to place the placement tray 206 into the inner cavity of the furnace body 101. The heating rod 102 heats the workpiece and drives the servo motor 201. The servo motor 201 drives the gear 203 to rotate through the rotating shaft 202 and the L-shaped post. The gear 203 rotates around the rotating shaft 202. At the same time, since the gear 203 is meshed with the internal gear ring 204, the gear 203 can drive the connecting post 205 to rotate. In summary, when the placement tray 206 rotates around the rotating shaft 202, it will also rotate around the gear 203, so that the workpiece on the surface of the placement tray 206 is heated evenly, avoiding uneven heating caused by one side being heated more.
[0013] Reference Figures 1-4 A temperature controller 3 is fixedly connected to the side wall of the furnace body 101, and the temperature controller 3 is fixedly connected to the heating rod 102. A protective atmosphere pipe 301 and a cooling gas pipe 302 are fixedly connected to the bottom of the side wall of the furnace body 101, and the protective atmosphere pipe 301 is located above the cooling gas pipe 302. An exhaust pipe 303 is fixedly connected to the top of the cover plate 2. It should be noted that the temperature controller 3 can control the heating temperature and time of the heating rod 102. The protective atmosphere is introduced into the furnace body 101 through the protective atmosphere pipe 301 so that the gas in the furnace body 101 can be discharged from the exhaust pipe 303. After sintering is completed, cooling gas is introduced into the furnace body 101 through the cooling gas pipe 302 to rapidly cool the furnace body 101.
[0014] Reference Figures 1-4 Telescopic cylinders 4 are fixedly connected to both sides of the top of the main board 1, and the telescopic cylinders 4 are fixedly connected to the cover plate 2. A sealing block 401 is fixedly connected to the bottom of the cover plate 2, and a sealing groove 402 is opened on the top of the furnace body 101, and the sealing block 401 can extend into the inner cavity of the sealing groove 402. It should be noted that the cover plate 2 can be moved up and down by the telescopic cylinder 4, which facilitates feeding and unloading. At the same time, when the cover plate 2 is engaged with the furnace body 101, the sealing block 401 at the bottom of the cover plate 2 extends into the inner cavity of the sealing groove 402 opened at the top of the furnace body 101, which enhances the sealing and heat preservation effect of the furnace body 101.
[0015] Operation method: Place the workpiece on the surface of the placement tray 206, then insert the limiting post 208 on the top of the connecting tray 207 into the placement tray 206, and then fix it with a nut. At this time, the limiting post 208 restricts the workpiece on the surface of the placement tray 206. Through the telescopic cylinder 4, the placement tray 206 is placed in the inner cavity of the furnace body 101. The workpiece is heated by the heating rod 102, and at the same time, the servo motor 201 is driven. The servo motor 201 drives the gear 203 to rotate through the rotating shaft 202 and the L-shaped column. The gear 203 rotates around the rotating shaft 202. At the same time, since the gear 203 is meshed with the internal gear ring 204, the gear 203 can drive the connecting post 205 to rotate. In summary, when the placement tray 206 rotates around the rotating shaft 202, it will also rotate around the gear 203, so that the workpiece on the surface of the placement tray 206 is heated evenly, avoiding uneven heating caused by high heating on one side. The temperature controller 3 controls the heating temperature and time of the heating rod 102. The protective atmosphere is introduced into the furnace body 101 through the protective atmosphere pipe 301 so that the gas in the furnace body 101 can be discharged from the exhaust pipe 303. After sintering is completed, cooling gas is introduced into the furnace body 101 through the cooling gas pipe 302 to quickly cool the furnace body 101. Secondly, the cover plate 2 can be moved up and down through the telescopic cylinder 4 to facilitate feeding and unloading.
