The ends of the multiple push-pull plates away from the sliders are simultaneously rotatably connected to the lifting plate. A number of equally spaced limit blocks are floatingly installed on the outer peripheral wall of the rotating rod one, and limit grooves that are compatible with the limit blocks are opened at the positions of the limit blocks on the inner peripheral wall of the lifting plate.

[0009] Furthermore, the transmission assembly includes a bevel gear 1 fixedly mounted at the bottom end of a rotating rod 1, and a bevel gear 2 rotatably mounted on the inner wall of one side of the inner cavity of the box and meshing with the bevel gear 1.

[0010] Furthermore, the rotating shaft of the second bevel gear and the central axis of the second rotating rod are parallel to each other, and the rotating shaft of the second bevel gear and the second rotating rod are driven by a pulley.

[0011] Furthermore, a door is hingedly connected to one side of the box body.

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0022] See also Figure 1-4 As shown, this embodiment provides a curing box for grinding wheel production, including a box body 1, a box door 2 is hingedly connected to one side of the box body 1, a heating plate 3 is fixedly installed on the top of the inner cavity of the box body 1, a heater for heating the heating plate 3 is installed on the top of the box body 1, a fixing plate 4 is fixedly installed in the inner cavity of the box body 1, a rotating rod 5 is rotatably installed on the top of the fixing plate 4, a support plate 6 is fixedly installed on the top of the rotating rod 5, a plurality of guide rods 7 are fixedly installed on the support plate 6, and a slider 8 is slidably installed on the outer peripheral wall of the plurality of guide rods 7, a clamping plate 9 is fixedly installed on the top of the slider 8, and a spring 10 sleeved on the outer peripheral wall of the guide rod 7 is fixedly installed between the slider 8 and the support plate 6;

[0023] A lifting plate 11 is slidably installed on the outer peripheral wall of the rotating rod 5, and a push-pull plate 12 is rotatably installed at the bottom of the multiple sliders 8. The ends of the multiple push-pull plates 12 away from the sliders 8 are all rotatably connected to the lifting plate 11. A plurality of equally spaced limit blocks 13 are floatingly installed on the outer peripheral wall of the rotating rod 5. Limiting grooves 14 that are compatible with the limit blocks 13 are opened at the positions of the inner peripheral wall of the lifting plate 11 corresponding to the limit blocks 13;

[0024] When the lifting plate 11 moves upward along the rotating rod 5, the plurality of push-pull plates 12 will push the plurality of sliders 8 respectively, so that the plurality of sliders 8 will slide along the extension direction of the plurality of guide rods 7 respectively, and respectively drive the plurality of clamping plates 9 to move away from each other at equal distances with the central axis of the rotating rod 5 as the center, thereby causing the sliders 8 to squeeze the plurality of springs 10 respectively, so that the plurality of springs 10 are simultaneously in a stressed state, thereby expanding the size between the plurality of clamping plates 9, otherwise the size between the plurality of clamping plates 9 will be reduced, and the elastic potential energy of the plurality of springs 10 that are in a stressed state will be released. When the limit block 13 on the outer peripheral wall of the rotating rod 5 is clamped in the limit groove 14 on the inner peripheral wall of the lifting plate 11, the lifting plate 11 will be restricted to a certain extent, so that when the rotating rod 5 drives the support plate 6 to rotate, the plurality of sliders 8 on the support plate 6 that tend to move away from each other due to inertia are restricted, thereby preventing the plurality of clamping plates 9 from loosening the fixed clamping of the grinding wheel;

[0025] A bevel gear 15 is fixedly installed at the bottom end of the rotating rod 15, and a rotating rod 2 16 is rotatably installed on the top of the inner cavity of the box body 1.

A driving motor for driving the bevel gear 2 18 to rotate is installed on the box body 1, and the bevel gear 2 18 and the rotating rod 2 16 are driven by a pulley.

[0026] When the bevel gear 2 18 rotates, it drives the rotating rod 1 5 to rotate through the bevel gear 1 15, and drives the rotating rod 2 16 to rotate synchronously through the pulley. The rotating rotating rod 2 16 drives the plurality of fan blades 17 to fan the airflow at the bottom of the heating plate 3, and the heated gas at the bottom of the heating plate 3 is quickly and evenly fanned to the inner cavity of the box 1;

[0027] When the present invention is in use, first open the box door 2, advance the grinding wheel to be cured into the inner cavity of the box body 1, then expand the distance between the plurality of clamping plates 9, so that the plurality of springs 10 are in a stressed state, and after the grinding wheel to be cured is placed between the plurality of clamping plates 9, release the tension on the plurality of clamping plates 9, so that the plurality of stressed springs 10 release their elastic potential energy, and drive the plurality of clamping plates 9 to move toward the central axis direction of the rotating rod 5 at the same time through the plurality of sliders 8, until the inner walls of the plurality of clamping plates 9 are in contact with the outer peripheral wall of the grinding wheel, so as to clamp the grinding wheel firmly, and then close the box door 2, heat the heating plate 3, and then rotate the bevel gear 2 18, so that the bevel gear 2 18 drives the rotating rod 5 to rotate through the bevel gear 15, and The pulley drives the second rotating rod 16 to rotate, so that the first rotating rod 5 drives the grinding wheel clamped on the support plate 6 to rotate, and the second rotating rod 16 drives several fan blades 17 to quickly and evenly fan the gas heated by the heating plate 3 into the inner cavity of the box body 1. The grinding wheel in a rotating state will disperse the heat fanned to its surface, so that the heat in the curing process can be more effectively transferred to various parts of the grinding wheel, reducing local overheating, improving curing efficiency, shortening curing time, and helping to disperse the stress caused by thermal expansion and contraction, reducing the risk of deformation of the grinding wheel during the curing process. After the grinding wheel has completed curing and cooling, the box door 2 is opened to expand the distance between the several clamping plates 9 and take the grinding wheel out of the box body 1.
