Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically to a double-hole type bonded grinding wheel. Background Technology

[0002] A grinding wheel is a bonded abrasive tool in which abrasive is bonded into a certain shape and has a certain strength by a bonding agent. Most grinding wheels are round with a through hole in the center, and are disc-shaped. They are usually used in a high-speed rotating state.

[0003] Therefore, the fit between the hole and the assembly shaft is very important. If the fit clearance is too small, it will cause the grinding wheel hole to crack during assembly, making it unsafe to use. If the fit clearance is too large, it will cause vibration during use, which will not only affect the grinding effect, but also cause the grinding wheel to collide with the workpiece. In severe cases, it may cause it to burst, causing injury to personnel and equipment. Utility Model Content

The use of a receiving plate can effectively avoid friction and vibration caused by changes in the gap between the grinding wheel and the equipment, ensuring the safety of the grinding wheel in use and solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-hole type bonded grinding wheel, comprising a grinding wheel component, wherein the annular surface of the grinding wheel component is configured as a cutting surface, and both sides of the grinding wheel component are configured as flat grinding surfaces, wherein the surface of the flat grinding surface is provided with a grinding wheel groove, and a receiving plate is installed inside the grinding wheel groove, the receiving plate is distributed on both sides of the grinding wheel component, and a transmission connecting rod is provided between the receiving plates.

[0006] Furthermore, bolts are provided at both ends of the transmission connecting rod, and the bolts are connected to the transmission connecting rod through internal threads.

[0007] Furthermore, the bottom of the receiving plate is provided with an integrally formed edge, and a pre-tension spring is provided inside the receiving plate, wherein the two ends of the pre-tension spring are respectively attached to the receiving plate and the grinding wheel groove.

[0008] Furthermore, the outer surface of the grinding wheel groove is provided with a transmission slot, and positioning holes are provided around the transmission slot. The positioning holes and the transmission slot penetrate the grinding wheel.

[0009] Furthermore, the transmission link extends into the preload spring and is connected to the grinding wheel via a transmission slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model allows the grinding wheel to be assembled and used with a handheld grinding wheel machine or a machine tool grinding wheel machine. When used with a machine tool grinding wheel machine, receiving plates need to be installed on both sides of the grinding wheel. Then, the middle of the grinding wheel is connected to the motor through a transmission connecting rod, thereby realizing the high-speed rotation of the grinding wheel. The workpiece is mainly ground by the cutting surface. When used with a handheld grinding wheel machine, only one receiving plate needs to be installed. The receiving plate is connected to the handheld device, and the workpiece is ground by the flat grinding surface on the other side.
