Problems solved by technology

[0002] In the prior art, the organic binder cup-shaped polishing wheel is usually a moderate elastomer, which is limited by the internal abrasives, fillers, pore-forming and bonding strength of the polishing wheel, and its rotational strength of the polishing wheel is relatively poor. It is difficult to work under high speed conditions, which greatly limits the efficient polishing
[0003] The improvement method currently used is mainly to increase the bonding strength of the bonding agent. After the bonding agent strength is increased, the elasticity of the polishing wheel is likely to decrease, and burns are prone to occur during use, and the degree of improvement is limited.
In addition, high-speed and high-efficiency polishing, the grinding heat is relatively large, if the amount of pore formation to improve the heat resistance of the polishing wheel is increased by increasing the chip capacity and water absorption, it is difficult to deal with the improvement of the strength, and it is easy to cause the elasticity of the polishing wheel at high speed. The deformation is large, so that the grinding end face of the polishing wheel is deformed and in an unstable state

Embodiment 1

[0052] like Figure 1 to Figure 3 As shown, a polishing wheel with a protective structure includes a base plate 1, an outer ring 2 and an abrasive ring 3, the outer ring 2 and the abrasive ring 3 are fixed on the base base plate 1, and the outer ring 2 fixedly set on the abrasive ring 3, the wear rate of the abrasive ring 3 is lower than the wear rate of the outer ring 2; the abrasive ring 3 is provided with a plurality of water channels for guiding cooling water to its grinding end surface 4.

[0053]Among them, the outer ring 2 is a high-strength continuous ring made of nylon plastic; the outer ring 2 can protect the abrasive ring 3 with high rotational strength, and can withstand the abrasive ring 3 without breaking under the action of grinding force and centrifugal force, ensuring The polishing wheel is under the condition of the set speed to avoid bursting; the base plate 1 is provided with a groove corresponding to the outer ring 2, and the lower end of the outer ring 2...

Embodiment 2

[0062] like image 3 and Figure 4 As shown, on the basis of Embodiment 1, the present embodiment divides a plurality of said nodules 3.1 into soft nodules 3.1.1 and hard nodules 3.1.2; said soft nodules 3.1.1 and The hard nodules 3.1.2 are arranged alternately; during the grinding process of multiple nodules 3.1, the soft nodules 3.1.1 are elastically deformed and form a gap with the hard nodules 3.1.2 Through the sink4.

[0063] In this embodiment, during the grinding process of the workpiece 8 by the abrasive ring 3, when the hard nodule 3.1.2 is in contact with the workpiece 8 and receives force, the hard nodule 3.1.2 moves toward the adjacent soft nodule 3.1.1 Extrusion, the adjacent soft segment 3.1.1 has good elastic deformation ability, can withstand the extrusion force of the hard segment 3.1.2, and forms the elastic effect of displacement deformation to let the knife, the hard segment 3.1.2 There is a slight deformation and a gap between the soft segment 3.1.1, th...

Embodiment 3

[0065] like Figure 5 and Image 6 As shown, in this embodiment, on the basis of Embodiment 1, an inner ring 5 that interferes with the inner wall of the abrasive ring 3 is fixedly arranged in the abrasive ring 3, and a confluence plate is fixedly arranged on the base plate 1. 6 and the pressure plate 7 sleeved on the confluence plate 6, the confluence plate 6 is in the inner ring 5, and the pressure plate 7 presses the confluence plate 6, the inner ring 5 and the abrasive ring 3 on the matrix on base plate 1. The wear rate of the abrasive ring 3 is less than that of the inner ring 4 and the outer ring 2 .

[0066] In this embodiment, the pressure plate 7 is used to fix the confluence plate 6, the inner ring 5 and the abrasive ring 3 on the base plate 1, and the outer ring 2 and the inner ring 5 are used to limit and fix the abrasive ring 3, so that the abrasive ring 3 is more stable , to ensure that the rotational strength of the abrasive ring 3 satisfies the conditions of...

Abstract

The invention relates to a polishing wheel with a protection structure. The polishing wheel comprises a base body bottom plate, an outer ring and an abrasive ring, the outer ring and the abrasive ring are both fixedly arranged on the base body bottom plate, and the outer ring fixedly sleeves the abrasive ring; a plurality of water through grooves for guiding cooling water to flow to the grinding end face of the abrasive ring are formed in the abrasive ring; and the abrasion rate of the abrasive ring is smaller than that of the outer ring. Compared with the prior art, the polishing wheel can assist in improving the strength of the abrasive ring, the applicable rotating speed range of the abrasive ring is widened, the cooling effect of the abrasive ring is improved, it is ensured that the rotating strength of the abrasive ring meets the use condition, the polishing wheel is in a stable grinding state in the grinding process, and high-rotating-speed and efficient polishing is achieved.
