Description

Technical Field

[0001] The utility model relates to the technical field of cubic boron nitride single crystal abrasives, and more specifically, to a ball milling device for processing cubic boron nitride single crystal abrasives. Background Art

[0002] Cubic boron nitride is another new product that has emerged after the advent of artificial diamond. It has high hardness, thermal stability and chemical inertness, as well as excellent properties such as good infrared transmittance and wide bandgap width. The existing ball milling device for cubic boron nitride single crystal abrasive processing usually uses a ball milling device to grind it when in use. When the ball milling device is working, it will generate a lot of impact, but the existing ball milling device does not have a shock absorption function. After the ball milling device is subjected to vibration caused by the impact for a long time, it will cause damage to the internal structure, thereby shortening the service life of the ball milling device and reducing the practicality of the ball milling device.

[0003] The utility model patent with patent publication number CN202022559410.3 discloses a ball mill for processing cubic boron nitride single crystal abrasives. The utility model drives the cylinder to rotate through a driving device. When the cylinder rotates, the internal grinding beads are used to grind the cubic boron nitride single crystal abrasives. At the same time, the grinding beads will generate impact when grinding the cubic boron nitride single crystal abrasives. The impact will be transmitted to the outside through the positioning ring, driving device, support plate, shock absorber and outer shell. When the impact passes through the shock absorber, the shock absorber will absorb the impact, thereby reducing the vibration caused by the impact and extending the service life of the ball mill.

[0004] However, when this structure is actually used, since the device generates a large amount of heat during grinding, and the heat is gathered at a high point inside the device, the heat dissipation holes and fans provided in the original device cannot effectively dissipate the large amount of heat inside the device, which is not conducive to the use of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a ball milling device for cubic boron nitride single crystal abrasive processing to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ball milling device for cubic boron nitride single crystal abrasive processing, comprising a shell, a support column is provided at the bottom of the shell, a processing cylinder is provided inside the shell, a ventilation and heat dissipation mechanism is provided inside the shell, the ventilation and heat dissipation mechanism comprises a cooling fan, the cooling fan is arranged inside the shell, a placement groove is provided on the bottom surface of the shell, the cooling fan and the placement groove are detachably connected, a ventilation groove is provided on the surface of the bottom plate of the shell, the number of the ventilation grooves is set to multiple, and the cross-sectional shape is set to be rectangular, a heat dissipation port is provided on the top surface of the shell, a guide plate is provided on the top of the shell, a drainage fan is provided on one side of the guide plate, and the number of the drainage fans is set to multiple.

[0007] Through the above scheme, it can be seen that the cooling fan is installed inside the placement groove at the bottom of the shell, and then when the processing cylinder rotates inside the shell, the cooling fan can quickly blow the heat inside the shell to the heat dissipation port on the top of the shell. When the heat enters the heat dissipation port, the guide plate will prohibit the heat from rising directly, and the drainage fan on one side of the guide plate will guide the heat to the outlet, and finally realize the heat discharge. The setting of the guide plate can prevent external dust from falling directly into the inside of the shell, thereby improving the dustproof effect of the device while improving the heat dissipation effect.

[0008] Preferably, a mounting groove is provided on the surface of the support column, a return spring is provided inside the mounting groove, the bottom of the return spring is fixedly connected to the top of the mounting groove, a damper is provided on one side of the return spring, the top of the return spring is fixedly connected to the bottom of the outer shell, a rubber block is provided on the top of the support column, the number of the rubber blocks is set to be several, the top of the rubber block is connected to the bottom of the outer shell, and the bottom is connected to the support column, the bottom of the guide plate is fixedly connected to the top of the outer shell, and the number of the guide plates is set to be several.

[0009] Through the above scheme, it can be seen that by using the return spring in conjunction with the damper, when the processing cylinder rotates inside the shell, the impact force transmitted is weakened by the damper and the return spring, thereby achieving a shock absorbing effect. At the same time, the rubber block can also assist the return spring and the damper to weaken the impact force, thereby reducing the damage to the shell caused by the impact force and improving the practicability of the device.

[0010] Technical effects and advantages of the utility model:

[0011] By setting a ventilation and heat dissipation mechanism, the heat dissipation fan is installed inside the placement groove at the bottom of the shell, and then when the processing cylinder rotates inside the shell, the heat dissipation fan can quickly blow the heat inside the shell to the heat dissipation port on the top of the shell. When the heat enters the heat dissipation port, the guide plate will prohibit the heat from rising directly, and the drainage fan on one side of the guide plate will guide the heat to the outlet, and finally realize the heat discharge. The setting of the guide plate can prevent external dust from falling directly into the inside of the shell, thereby improving the dustproof effect of the device while improving the heat dissipation effect;

[0012] By providing a return spring and using the return spring in conjunction with a damper, when the processing cylinder rotates inside the shell, the impact force transmitted is weakened by the damper and the return spring, thereby achieving a shock absorbing effect. At the same time, the rubber block can also assist the return spring and the damper in weakening the impact force, thereby reducing the damage to the shell caused by the impact force and improving the practicability of the device.

The number of the drainage fans 9 is set to be multiple, so that by installing a cooling fan 4 inside the placement groove 5, the heat inside the shell 1 is guided upward by the cooling fan 4, and then the heat enters the heat dissipation port 7, and finally the heat is discharged outward under the action of the drainage fan 9 on one side of the guide plate 8. According to the law of heat floating, the cooling fan 4 is used to assist, so that the heat inside the shell 1 can be discharged more quickly, thereby improving the heat dissipation effect and cooling efficiency of the device, and improving the practicability of the device.

[0021] As attached Figure 1-4 As shown, a mounting groove 10 is provided on the surface of the support column 2, and a return spring 11 is provided inside the mounting groove 10.
