[0024] The purpose of this invention is to provide a protective cover for a double-sided grinding machine and a double-sided grinding machine to solve the problems existing in the prior art, reduce the injury rate of operators, improve safety, and reduce pollution to the surrounding environment.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] This embodiment provides a protective cover for a double-sided grinding machine, such as... Figures 1-2As shown, the machine includes an annular protective cover 1, a sliding member 2, and a connecting member 3. The annular protective cover 1 is fitted over the upper grinding disc 4. The annular protective cover 1 is connected to the sliding member 2 via the connecting member 3. The sliding member 2 is slidably connected to the cylinder lifting rod 6 of the upper grinding disc 4, and the sliding member 2 can abut against the bottom of the cylinder lifting rod 6 of the upper grinding disc 4 to prevent the sliding member 2 from detaching from the cylinder lifting rod 6 of the upper grinding disc 4. When the double-sided grinding machine is working, the upper grinding disc 4 descends to grind the product. The sliding member 2 follows the cylinder lifting rod 6 of the upper grinding disc 4 and descends, driving the annular protective cover 1 to descend as well. The annular protective cover 1 surrounds the upper grinding disc 4 and the lower grinding disc 5. The annular protective cover 1 can effectively block the splashes generated during grinding, preventing splashes from injuring the operator's body. At the same time, it can reduce the spread of dust and debris generated during grinding into the surrounding environment, reducing pollution to the workshop environment and keeping the workplace clean. Moreover, the annular protective cover 1 can also prevent the operator's limbs from accidentally coming into contact with the operating grinding parts, avoiding serious accidents such as entanglement and crushing. The grinding machine generates considerable noise during operation. The protective cover can block the transmission of noise to a certain extent, reducing the damage to the operator's hearing and improving the working environment. When the double-sided grinding machine is not in operation, the cylinder lifting rod 6 of the upper grinding disc 4 drives the upper grinding disc 4 to rise. The sliding part 2 first abuts against the bottom of the cylinder lifting rod 6 of the upper grinding disc 4, and then rises together with the cylinder lifting rod 6 of the rising upper grinding disc 4. This facilitates the operator's loading and unloading of materials, debugging, maintenance, and other operations, reducing the limitation of operating space and improving work efficiency. The sliding part 2 is slidably connected to the cylinder lifting rod 6 of the upper grinding disc 4. The position of the sliding part 2 on the cylinder lifting rod 6 can be flexibly adjusted according to the different thicknesses of the workpiece to be ground, ensuring that the annular protective cover 1 can always surround the upper grinding disc 4, the workpiece to be ground, and the lower grinding disc 5, meeting different working requirements and having strong adaptability.

[0028] In the implementation of this embodiment, it is further preferred that, as follows: Figure 3 As shown, the sliding component 2 includes two semi-circular clamps 7 and fasteners. The two semi-circular clamps 7 are spliced ​​together and fixed into a complete circular clamp by the fasteners. Each end of the semi-circular clamp 7 has a connecting lug, with bolt holes 8 on the connecting lugs. The fasteners are bolts 8 and nuts 9. The bolts 8 pass through the bolt holes 8 of the mating connecting lugs and are threadedly connected to the nuts 9, thus fixing the two semi-circular clamps 7 together. The spliced ​​clamps fixed by the bolts 8 are easy to disassemble and install, facilitating operation.

[0029] In a further preferred embodiment of this invention, the radius of the circular clamp is 5mm-10mm larger than the radius of the cylinder lifting rod 6 of the upper grinding disc 4. A certain gap exists between the circular clamp and the cylinder lifting rod 6, which can reduce the friction between the circular clamp and the cylinder lifting rod 6. A protective pad is fixedly connected to the inner side wall of the semi-circular clamp 7. The protective pad can also reduce the friction between the circular clamp and the cylinder lifting rod 6, reduce the damage to the cylinder lifting rod 6, and improve the service life.

[0030] In a further preferred embodiment of this invention, the connector 3 includes multiple connecting rods, which are evenly distributed along the circumference of the annular protective cover 1 to ensure uniform force distribution on each connecting rod. One end of each connecting rod is fixedly connected to the top of the annular protective cover 1, and the other end is fixedly connected to the sliding member 2.

[0031] In a further preferred embodiment of this invention, the angle between the connecting rod and the center line of the annular protective cover 1 is 45°.

[0032] In a further preferred embodiment of this invention, the annular protective cover 1 is a circular annular protective cover 1. The circular annular protective cover 1, while ensuring a certain level of safety, allows the operator to conveniently observe the grinding process from above and adjust the grinding parameters or handle emergencies in a timely manner.

[0033] In this embodiment, it is further preferred that the material of the annular protective cover 1 is stainless steel. Stainless steel protective covers have high strength, good durability, and can withstand greater impact forces.
