Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically to a high wear-resistant grinding wheel. Background Technology

[0002] Grinding wheels are bonded abrasive tools with a certain strength, formed by bonding ordinary abrasive grains into a specific shape using a binder. They have a wide range of applications. During use, the high-speed rotation of the grinding wheel can perform rough grinding, semi-finishing, and fine grinding of the outer and inner diameters, planes, and various profiles of workpieces, as well as grooving and cutting. However, some existing grinding wheels have poor wear resistance. During prolonged grinding of workpieces, the surface of the grinding wheel will wear out quickly, reducing the service life of the grinding wheel and affecting the grinding process.

[0003] Secondly, existing grinding wheels generate high heat during the grinding process. If this heat is not dissipated in time, it can cause burns or cracks on the surface of the workpiece, which cannot guarantee the quality of the workpiece after grinding. At the same time, it shortens the service life of the grinding wheel and, in severe cases, can cause the grinding wheel to explode, threatening the health and safety of the workers.

[0004] Therefore, a new grinding wheel needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-wear-resistant grinding wheel. The specific solution is as follows: A high wear-resistant grinding wheel includes a base body with a mounting hole at its center and multiple positioning grooves around the mounting hole. A grinding body is provided around the periphery of the base body. The grinding body includes an inner skeleton with an abrasive layer fixed on it. The edge surface of the abrasive layer is provided with a diamond particle layer. The inner skeleton includes two annular clamping plates with multiple reinforcing bars welded between them. One end of each reinforcing bar is welded to an alloy block, and the other end is connected to the base body. Multiple anchor rods are provided on the clamping plates. Annular reinforcing plates are provided on both sides of the grinding body and are fitted onto the base body. Both the reinforcing plates and the grinding body have corresponding through holes. The reinforcing plates and the grinding body are fixed together by bolts and nuts corresponding to the through holes.

[0006] Based on the above, glass fiber mesh is provided on both sides of the grinding body.

[0007] Based on the above, the outer side of the reinforcing plate is provided with multiple fan blades.

[0008] Based on the above, multiple chip removal grooves are evenly distributed along the circumference on both sides of the grinding body.

[0009] Based on the above, the inner wall of the chip removal groove is provided with a metal strip.

[0010] Based on the above, the substrate is also provided with multiple heat dissipation holes.

[0011] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages: The high wear-resistant grinding wheel provided by this utility model has a structural design that not only ensures the structural strength of the grinding wheel, but also ensures the heat dissipation capacity and chip removal efficiency of the grinding wheel, thus ensuring the structural strength and service life of the grinding wheel. In addition, the structural design of the diamond layer and alloy block can ensure the grinding performance of the grinding wheel during the grinding process. Attached Figure Description

[0015] The technical solution of this utility model will be further described in detail below through specific embodiments. Example

[0016] like Figure 1-2 As shown, this utility model provides a high wear-resistant grinding wheel, including a base 1. The base 1 has a mounting hole 1-2 at its center, and multiple positioning grooves 1-3 around the base 1 corresponding to the mounting hole 1-2. A grinding body 2 is provided around the periphery of the base 1. The grinding body 2 includes an inner skeleton, on which an abrasive layer 2-5 is fixed. Diamond particle layers 2-6 are provided on the edge surface of the abrasive layer 2-5. The inner skeleton includes two annular clamping plates 2-1. Multiple reinforcing bars 2-2 are welded together. One end of each reinforcing bar 2-2 is welded to an alloy block 2-3, and the other end of each reinforcing bar 2-2 is connected to the base body 1. Multiple anchor bars 2-4 are provided on the clamping plate 2-1. Both sides of the grinding body 2 are provided with annular reinforcing plates 3. The reinforcing plates 3 are sleeved on the base body 1. Both the reinforcing plates 3 and the grinding body 2 are provided with corresponding through holes. The reinforcing plates 3 and the grinding body 2 are fixed together by bolts and nuts 3-1 corresponding to the through holes.
