Description

Technical Field

[0001] The utility model belongs to the field of grinding wheel manufacturing, and more specifically, particularly relates to a grinding wheel curing device. Background Art

[0002] A grinding wheel is a rotating abrasive tool composed of abrasive grains, a binder, and pores, and is commonly used in the grinding operations of materials such as metals, wood, ceramics, and glass. Currently, the manufacturing process of grinding wheels includes four steps: batching, forming, curing, and dressing. Among them, the curing operation after the grinding wheel is formed is to melt and bond the metal binder and diamond particles in the grinding wheel at a high temperature to form an abrasive layer. To complete the batch production of multiple groups of grinding wheels, multiple groups of grinding wheels are usually stacked and placed in an oven for high-temperature heating and baking. Since the grinding wheels are stacked, the upper and lower sides of the grinding wheels are closed to each other, reducing the heating area of the grinding wheels. In addition, the position of the heat radiation area of the traditional oven is fixed, resulting in the grinding wheels being unable to be heated and cured on the surface in all directions, seriously affecting the curing quality of the grinding wheels.

[0045] The following further describes the implementation manner of the present utility model in detail in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0046] As Figures 1-8 shown, the present utility model provides a grinding wheel curing device, including a base 1; a housing 2 is welded and connected to the upper side surface of the base 1, a support plate 6 and a support plate 14 are welded and connected to the outer side surface of the housing 2 in sequence from top to bottom, a steering motor 13 is connected to the upper side surface of the support plate 14 by bolts, a driving gear 24 is installed on the motor shaft of the steering motor 13, a steering gear 12 is meshed and connected to the outer side surface of the driving gear 24, and the steering gear 12 is welded and connected to the outer side surface of a guiding pillar 9; it further includes a separating and fixing device 15, a heating controller 16, an electric heating tube 17 and a grinding wheel part 23; the bottom end of the guiding pillar 9 is rotatably connected to the upper side surface of the base 1, the top end of the guiding pillar 9 is welded and connected to a top plate 10, a rotating plate 7 is welded and connected to the outer side surface of the guiding pillar 9, a lifting motor 21 is connected to the lower side surface of the rotating plate 7 by bolts, a threaded rod 11 is installed on the motor shaft of the lifting motor 21, a sliding plate 8 is meshed and connected to the outer side surface of the threaded rod 11; a sealing cover 3 is welded and connected to the lower side surface of the sliding plate 8; a driven gear 19 is welded and connected to the bottom end of a rotating rod 5, a bracket 22 is welded and connected to the lower side surface of the driven gear 19, a hanging ring is provided on the lower side surface of the bracket 22, and a hanging rod 20 is hung on the hanging ring; a driving motor 4 is connected to the upper side surface of the sealing cover 3 by bolts, a driving gear 18 is installed on the motor shaft of the driving motor 4, and the driving gear 18 is meshed and connected to the outer side surface of the driven gear 19; the heating controller 16 is connected to the upper side surface of the base 1 by bolts, and the heating controller 16 is connected to the electric heating tube 17 through a wire; the separating and fixing device 15 includes a bottom ring 1501, a support rod 1502 and a limiting button 1503; a support rod 1502 is welded and connected to the upper side surface of the bottom ring 1501, a limiting button 1503 is meshed and connected to the outer side surface of the support rod 1502, a threaded through hole penetrating through the front and back is provided at the center position of the front side surface of the limiting button 1503, and a grinding wheel part 23 is placed on the upper side surface of the support rod 1502.

[0047] When the utility model cures the grinding wheel, first place the partition fixing device 15 on the disc at the bottom end of the suspension rod 20, then place the grinding wheel member 23 on the upper side surfaces of the six support rods 1502, and then respectively turn the six limit buttons 1503. Since the threaded through holes of the limit buttons 1503 are engaged with the threads on the outer side surfaces of the support rods 1502, the six limit buttons 1503 respectively move along the threaded surfaces of the six support rods 1502, so that the six limit buttons 1503 clamp the lower edge of the grinding wheel member 23, enabling the grinding wheel member 23 to be stably placed on the six support rods 1502 of the partition fixing device 15. Then, stack the other partition fixing devices 15 and the remaining grinding wheel members 23 at intervals in the same way as above. Then, hang the hook at the top end of the suspension rod 20 on the hanging ring at the bottom end of the support 22. The lifting motor 21 drives the threaded rod 11 to rotate. Since the threaded through hole of the sliding plate 8 is engaged with the thread on the outer side surface of the threaded rod 11, the threaded rod 11 drives the sealing cover 3 welded to the lower side surface of the sliding plate 8 to move upward. The sealing cover 3 drives the suspension rod 20 hung at the hanging ring of the support 22 to move upward. When the disc at the bottom end of the suspension rod 20 is higher than the outer shell 2, the steering motor 13 drives the driving gear 24 to rotate, and the driving gear 24 drives the guiding pillar 9 welded to the steering gear 12 to rotate. The guiding pillar 9 drives the sealing cover 3 welded to the sliding plate 8 to rotate until the sealing cover 3 is located directly above the outer shell 2. The lifting motor 21 reverses, and the sealing cover 3 drives the grinding wheel member 23 carried on the suspension rod 20 to descend into the inner part of the outer shell 2. The sealing rubber ring of the sealing cover 3 closely adheres to the edge position of the upper side surface of the outer shell 2 to seal the outer shell 2. The heating controller 16 controls the heating tube 17 to generate heat. At this time, the driving motor 4 drives the driving gear 18 to rotate, and the driving gear 18 drives the driven gear 19, and the driven gear 19 drives the support 22 welded to the lower side surface to rotate. The support 22 drives the suspension rod 20 hung at the bottom end to rotate, and the grinding wheel member 23 carried on the suspension rod 20 rotates synchronously. The grinding wheel member 23 is uniformly heated in all directions to complete the curing work of the grinding wheel member 23. After the curing of the grinding wheel member 23 is completed, the lifting motor 21 drives the threaded rod 11 to rotate again. The threaded rod 11 drives the sealing cover 3 to open upward through the sliding plate 8. The grinding wheel member 23 carried on the suspension rod 20 moves upward synchronously with the sealing cover 3 and disengages from the outer shell 2. Then, the steering motor 13 reverses, and the driving gear 24 drives the guiding pillar 9 welded to the steering gear 12 to rotate 90 degrees, so that the suspension rod 20 moves away from the upper side surface of the outer shell 2. After that, the lifting motor 21 reverses, and the grinding wheel member 23 carried on the suspension rod 20 falls with the sealing cover 3. Finally, remove the suspension rod 20 from the hanging ring of the support 22.

[0048] In the embodiments of the present disclosure, the number of the support rods 1502 is six groups. The support rods 1502 are distributed in an annular array around the central axis of the bottom ring 1501. Each group of support rods 1502 has an L-shaped structure. A thread is provided at the end of the L-shaped structure of the support rod 1502. The threaded through hole of the limit button 1503 is meshed and connected to the threaded structure of the support rod 1502, so that the six limit buttons 1503 clamp the grinding wheel member 23 at the bottom edge of the grinding wheel member 23, and the grinding wheel member 23 is stably placed on the upper end of the partition fixing device 15.

[0049] In the embodiments of the present disclosure, a convex column is provided on the upper side surface of the sliding plate 8. A threaded through hole penetrating up and down is provided at the center position of the top end of the convex column. The threaded rod 11 is meshed and connected to the threaded through hole of the convex column of the sliding plate 8. A through hole penetrating up and down is provided at a position close to the rear end of the sliding plate 8. The guiding support column 9 is inserted into the through hole of the sliding plate 8. The threaded rod 11 drives the sliding plate 8 to slide up and down along the guiding support column 9, completing the opening of the sealing cover 3 and the lifting and taking of the grinding wheel member 23 in the housing 2.

[0050] In the embodiments of the present disclosure, the number of the electric heating tubes 17 is six groups. The electric heating tubes 17 are distributed in an annular array around the central axis of the housing 2, so that the outer side surface of the cylindrical grinding wheel member 23 is uniformly heated from six directions.

[0051] In the embodiments of the present disclosure, an annular groove is provided on the lower side surface of the sealing cover 3. A ring-shaped rubber ring made of silica gel is bonded inside the groove. When the sealing cover 3 is closed with the upper side edge of the housing 2, the ring-shaped rubber ring is closely attached to the upper side surface of the housing 2 to seal the sealing cover 3 and the housing 2, preventing the heat inside the housing 2 from dissipating from the gap between the sealing cover 3 and the housing 2.

[0052] In the embodiments of the present disclosure, a hook is provided on the upper side surface of the suspension rod 20. The hook of the suspension rod 20 is hung on the hanging ring at the bottom end of the bracket 22, so that the grinding wheel member 23 carried by the suspension rod 20 is suspended in the housing 2. A disc structure is provided at the bottom end of the suspension rod 20. The diameter of the disc is larger than the diameter of the bottom ring 1501, so that the bottom ring 1501 is placed on the upper side surface of the disc, and a suspension distance is generated between the grinding wheel member 23 and the disc at the bottom end of the suspension rod 20 through the partition fixing device 15, reducing the contact area between the grinding wheel member 23 and the bottom disc of the suspension rod 20 and increasing the heating surface to ensure uniform heating of the grinding wheel member 23.

[0053] The installation methods, connection methods or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc. And the specific structures, models and coefficient indexes of all their components are their own technologies, and any implementation that can achieve their beneficial effects can be carried out. The above-mentioned driving motor 4, steering motor 13, heating controller 16, lifting motor 21 are common devices on the market. When purchasing and using them, only need to connect according to the user manual purchased together to use, so it will not be elaborated here.

[0054] The technical solution of the present utility model is not limited within the scope of the embodiments of the present utility model, and the technical content not described in detail in the present utility model is well-known technology.
