Description

Technical Field

[0001] The utility model belongs to the technical field of grinding wheel production, in particular to a grinding wheel forming and sintering device. Background Technique

[0002] A grinding wheel is a grinding tool in which ordinary abrasives are solidified into a certain shape by a binder and have a certain strength. It generally consists of abrasives, a binder, and pores. These three parts are often called the three elements of a vitrified grinding wheel. According to the different binders, grinding wheels can be divided into ceramic, resin, and rubber grinding wheels. After the grinding wheel is formed, it needs to be sintered and thermally cured by a sintering device.

[0003] Most of the existing grinding wheel sintering and forming devices directly place the grinding wheel to be sintered in a high-temperature furnace for firing or drive the grinding wheel to rotate parallelly to achieve uniform heating of the grinding wheel during sintering. However, in the above two sintering methods, in the first method, the heating of the grinding wheel is uneven, and in the second method, although the grinding wheel is fired by rotating parallelly, the lower end face of the grinding wheel cannot be turned over, resulting in poor heating effect. Therefore, a grinding wheel forming and sintering device is needed to solve the above problems.

[0004] For example, the existing Chinese patent number is: CN216228879U one-time forming and sintering device, including a sintering box and a sealing cover sleeved on the top of the sintering box. A placing component is arranged inside the sintering box, and a driving component is also arranged at the bottom of the sintering box; and the placing component and the sintering box are detachably connected through the driving component.

[0005] It can be seen that the above-cited patent documents also have the same problem. The above device uses parallel rotation of multiple grinding wheels at the same time to achieve uniform heating of the grinding wheels inside the sintering box. However, it is difficult to turn over the lower end face of the grinding wheel in this sintering method, so there will still be uneven sintering of the grinding wheel. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a grinding wheel forming and sintering device to solve the problems raised in the background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A grinding wheel forming and sintering device, including a box body for grinding wheel forming and sintering. A box door is hinged on the side wall of the box body, an observation window is opened on the box door, a resistance heating groove is opened on the box body, a rotating cylinder is rotatably connected inside the resistance heating groove, a toothed ring is fixedly sleeved on the outer side wall of the rotating cylinder, a first motor is fixedly installed inside the box body, a gear is fixedly sleeved at the end of the rotating shaft of the first motor, the gear meshes with the toothed ring, a support rod is fixedly connected inside the rotating cylinder, and a second motor is fixedly installed at the upper end of the support rod.

[0009] Preferably, annular grooves are formed in the upper ends of the first limiting disc and the second limiting disc respectively. A first turntable and a second turntable are respectively rotatably connected to the interiors of the two annular grooves. The rotating shaft of the second motor rotates through the first limiting disc and is fixedly connected to the lower end of the first turntable.

[0010] Preferably, a connecting column is fixedly connected to the upper end of the first turntable. A rotating rod is rotatably penetrated through the second turntable. The rotating rod rotates and extends below the second limiting disc. A sleeve is slidably connected to the side wall of the connecting column, and a cross bar is fixedly connected through the interior of the sleeve.

[0012] Preferably, an installation groove is formed inside the connecting column. A spring is fixedly connected to the interior of the installation groove. Strip-shaped holes are symmetrically penetrated through the side wall of the installation groove. The cross bar is slidably connected through the interior of the strip-shaped holes, and the cross bar is fixedly connected to the upper end of the spring.

[0013] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0014] For this grinding wheel forming and sintering device, when it is necessary to sinter the grinding wheel to be sintered, first press the sleeve downwards, simultaneously driving the clamping blocks fixedly connected to the inner wall of the sleeve to slide downwards and move out of the clamping grooves formed in the side wall of the rotating rod, thereby forming a gap between the connecting column and the rotating rod. At this time, the grinding wheel to be sintered is sleeved onto the connecting column through this gap. Then release the sleeve. At this time, the spring sleeve will re-clamp the clamping blocks inside the sleeve into the clamping grooves. Then start the second motor to drive the connecting column fixedly connected to its rotating shaft to rotate, and simultaneously drive the grinding wheel sleeved on its side wall to rotate. Then start the first motor to drive the gear and the toothed ring to rotate, thereby driving the rotating cylinder and the grinding wheel to rotate. Since the second motor has its own power supply, and a high-temperature resistant material is sleeved on the side wall of the second motor to protect the second motor. As the rotating cylinder rotates, when the first limiting disc and the second limiting disc are inverted, at this time the grinding wheel will slide downwards, thereby realizing turning over the grinding wheel and making it evenly heated. Compared with the prior art, this device can realize the rotation of the grinding wheel and also turn over the grinding wheel, thereby making the grinding wheel heated more evenly.

[0026] A first limiting disc 11 is rotatably penetrated through the rotating shaft of the second motor 10.

A second limiting disc 13 is fixedly connected to the upper ends of the two connecting rods 12. Annular grooves 14 are opened at the upper ends of the first limiting disc 11 and the second limiting disc 13. A first turntable 15 and a second turntable 23 are respectively rotatably connected inside the two annular grooves 14. The rotating shaft of the second motor 10 rotates through the first limiting disc 11 and is fixedly connected to the lower end of the first turntable 15. The second motor 10 will drive the first turntable 15 and the second turntable 23 to rotate. And the second motor 10 is self-powered, so there is no need to tow a wire and there will be no wire winding situation. And a high-temperature resistant material is sleeved on the side wall of the second motor 10 to protect the second motor 10 from being affected by high temperature.

[0027] A connecting column 16 is fixedly connected to the upper end of the first turntable 15. A rotating rod 17 is rotatably penetrated through the second turntable 23. The rotating rod 17 rotates and extends below the second limiting disc 13. A sleeve 18 is slidably connected to the side wall of the connecting column 16. A cross bar 21 is fixedly penetrated through the inside of the sleeve 18. Clamping blocks 22 are symmetrically and fixedly connected above the inside of the sleeve 18. Card slots are symmetrically opened on the side wall of the rotating rod 17. The card slots match with the clamping blocks 22. Thanks to the clamping of the sleeve 18, the connecting column 16 and the rotating rod 17 can drive the rotating rod 17 and the second turntable 23 to rotate while the connecting column 16 rotates. An installation groove 19 is opened inside the connecting column 16. A spring 20 is fixedly connected inside the installation groove 19. Strip-shaped holes are symmetrically penetrated through the side wall of the installation groove 19. The cross bar 21 is penetrated and slidably connected inside the strip-shaped holes, and the cross bar 21 is fixedly connected to the upper end of the spring 20.

[0028] Working principle

[0029] When the grinding wheel forming and sintering device needs to sinter the grinding wheel to be sintered, first press the sleeve 18 downward, so that the cross bar 21 fixedly connected horizontally inside the sleeve 18 moves downward along the strip-shaped through hole. Subsequently, the spring 20 fixedly connected to the cross bar 21 is compressed into the installation groove 19, and at the same time, the block 22 fixedly connected to the inner wall of the sleeve 18 is driven to slide downward and move out of the clamping groove opened on the side wall of the rotating rod 17, so as to form a gap between the connecting column 16 and the rotating rod 17. At this time, the grinding wheel to be sintered is sleeved onto the connecting column 16 through this gap. Then release the sleeve 18. At this time, the spring 20 will push the cross bar 21 and the sleeve 18 upward, so that the block 22 in the sleeve 18 is re-clamped into the clamping groove again.

[0030] At this time, start the second motor 10 to drive the connecting column 16 fixedly connected to its rotating shaft to rotate, and at the same time drive the grinding wheel sleeved on the side wall of the connecting column 16 to rotate. Then start the first motor 4 to drive the gear 5 fixedly sleeved at the end of its rotating shaft to rotate. The gear 5 drives the toothed ring 8 meshing with it to rotate, and the toothed ring 8 drives the rotating cylinder 7 and the grinding wheel sleeved on the connecting column 16 to rotate. At this time, because the second motor 10 has its own power supply, there is no need for a trailing wire and there will be no wire winding situation. And a high-temperature resistant material is sleeved on the side wall of the second motor 10 to protect the second motor 10 from being affected by high temperature. As the rotating cylinder 7 rotates, when the first limiting disc 11 and the second limiting disc 13 are inverted, at this time the grinding wheel will slide downward, so as to turn over the grinding wheel and make it heat evenly.
