[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a novel grinding device with an optimized grinding structure. Driven by a motor, the grinding rod pin achieves high-speed rotation with a linear velocity of 13-14 m / s. The rear grinding seat has a hollow structure. When rotating at high speed, large-mass materials and grinding zirconium beads can effectively break through the constraints of high viscosity and reach the grinding zone due to the large centrifugal force, thus improving grinding efficiency. The device utilizes the characteristics of conical surface mating to meet the transmission of large torque while also achieving easy disassembly.

[0027] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The diagram shown is an overall structural schematic of one embodiment of a novel grinding device according to this utility model. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The main structure of this embodiment includes a spindle 1, a three-phase asynchronous motor 3 and a silicon carbide ceramic liner 4. An inner tapered sleeve 2 is installed on the spindle 1, and a front grinding seat 8 is provided on the inner tapered sleeve 2. A rear grinding seat 9 is installed on the front grinding seat 8, and wear-resistant steel rod pins 7 are provided on the front grinding seat 8 and the rear grinding seat 9.

[0028] Several wear-resistant steel pins 7 are provided, and each wear-resistant steel pin 7 is locked to the front grinding seat 8 and the rear grinding seat 9 by a first internal hexagonal head screw 11. The inner cone sleeve 2 is locked to the front grinding seat 8 by a second internal hexagonal head screw 12. The main shaft 1 and the inner cone sleeve 2 are locked by a hexagonal head fully threaded bolt 10 and a thin internal hexagonal head screw 13. It also includes a three-phase asynchronous motor 3. A V-belt 5 is provided on the wheel at the output end of the three-phase asynchronous motor 3. A pulley 6 is provided on the side end of the main shaft 1, and the pulley 6 and the V-belt 5 are fitted together.

[0029] In practical use, the inner tapered sleeve 2 is installed on the spindle 1, and then the front grinding seat 8 is installed on the inner tapered sleeve 2. Since the inner tapered sleeve 2 and the front grinding seat 8 are in tapered surface fit, and since the central hole of the inner tapered sleeve 2 is a hole with an open long slot, its central hole diameter becomes smaller under the action of the tapered surface. Therefore, when the wrench tightens the three second internal hexagonal head screws 12, the axial force of the second internal hexagonal head screws 12 causes the inner and outer tapered surfaces to produce axial displacement, thus achieving an interference fit between the inner tapered sleeve 2 and the front grinding seat 8. At the same time, because the inner hole of the inner tapered sleeve 2 becomes radially smaller due to the tapered surface fit, an interference fit between the inner tapered sleeve 2 and the spindle 1 is achieved. The installation of the front grinding seat 8 is completed in one step. Conversely, disassembly is completed.

[0030] Install the rear grinding seat 9 onto the front grinding seat 8, and then tighten the six thin hex socket head cap screws 13 to complete the installation of the grinding seat on the spindle 1; conversely, disassembly is complete by tightening the rear grinding seat 9 onto the front grinding seat 8.

[0031] Install multiple wear-resistant steel pins 7 onto the front grinding seat 8 and the rear grinding seat 9 respectively, and then tighten the first internal hex socket head cap screw 11 to complete the installation of 48 wear-resistant pins; otherwise, disassembly is completed.

[0032] During use, the three-phase asynchronous motor 3 drives the rotating wheel to rotate, and the rotating wheel, together with the V-belt 5, drives the pulley 6 to rotate, thereby driving the main shaft 1 to rotate. At this time, the wear-resistant steel rod pin 7 will also rotate at high speed, with a linear speed of 13-14 m / s. During the rotation, the rear grinding seat 9 has a hollow structure. When rotating at high speed, the large mass of material and grinding zirconium beads can effectively break through the constraints of high viscosity and reach the grinding zone due to the large centrifugal force, thus improving the grinding efficiency.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
