Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding wheel technology, and in particular to an ultra-thin high-speed grinding wheel. Background Technology
[0002] High-speed grinding wheels are specifically designed for high-speed cutting and grinding, typically used in precision machining and high-efficiency grinding operations. Their main characteristic is their extremely high rotational speed, enabling fine cutting and grinding. High-speed grinding wheels are widely used in metal processing, ceramics processing, glass grinding, and other fields. The construction of a high-speed grinding wheel generally consists of three parts: abrasive, binder, and pores. Common abrasives include aluminum oxide, silicon carbide, and diamond, while commonly used binders include resins, ceramics, and metal-based materials. The performance of ultra-thin high-speed grinding wheels is closely related to the selection of these materials.
[0003] In traditional technology, high-speed grinding wheels are relatively fragile and are usually made of hard materials such as aluminum oxide and diamond abrasives. Therefore, they are prone to damage during transportation. Due to external impact, vibration or improper stacking, the surface or internal structure of the grinding wheel may be damaged, causing it to crack or lose precision, thus affecting the subsequent use effect and safety. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ultra-thin high-speed grinding wheel, comprising a grinding wheel, characterized in that: connecting flanges are fixedly connected to both sides of the grinding wheel, a protective mechanism is provided on the outside of the grinding wheel, the protective mechanism is used to protect the grinding wheel during transportation or installation, and a connecting mechanism is provided inside the grinding wheel, the connecting mechanism is used to install and connect the grinding wheel to machine equipment.
[0006] The protective mechanism includes an inner protective cover and an outer protective cover. The inner protective cover is slidably connected to the outside of the connecting flange, and the outer protective cover is slidably connected to the outside of the inner protective cover. Two mounting shells are fixedly connected to the outside of the outer protective cover.
[0007] As a further description of the above technical solution:
[0008] Both mounting shells have springs fixedly connected inside, and limit blocks are fixedly connected to opposite sides of the two springs. Pins are fixedly connected inside the two limit blocks, and opposite sides of the two pins penetrate the outside of the outer protective cover and engage with the outside of the inner protective cover.
[0009] As a further description of the above technical solution:
[0010] A fixing box is fixedly connected to the top of the mounting shell, a sliding plate is slidably connected inside the fixing box, a baffle plate is fixedly connected to the bottom of the sliding plate, and the bottom of the baffle plate abuts against the top of the limiting block.
[0011] As a further description of the above technical solution:
[0012] The limiting block is slidably connected inside the mounting housing.

[0022] 1. In this utility model, when transferring the grinding wheel, the inner and outer protective covers are installed on the outside of the grinding wheel to prevent damage during the transfer. When installing the grinding wheel, the handle is pulled outward to pull the pin rod, causing it to drive the limit block to compress the spring and retract into the mounting shell. The baffle plate automatically falls down under the influence of gravity, blocking the limit block and preventing it from moving. At this time, the inner protective cover can be slid out from inside the outer protective cover and completely removed for grinding wheel installation. This achieves the effect of protecting the grinding wheel during the transfer process through the protective mechanism, avoiding damage to the grinding wheel and improving the practicality of the device.
[0023] 2. In this utility model, when installing the grinding wheel, the screw is passed through the inside of the connecting flange using bolts, and then the grinding wheel is connected to the output shaft of the machining machine. Tightening the bolts prevents the grinding wheel from flipping or falling off under stress. Anti-slip pads enhance the connection and prevent the grinding wheel from slipping, achieving a quick connection between the grinding wheel and the operating machine through the connecting mechanism, thus improving the efficiency of the device.
