DETAILED DESCRIPTION

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] The present embodiment provides a grinding wheel frame of a grinding machine with a precision sliding bearing. The grinding wheel frame of the grinding machine with a precision sliding bearing has the function of protecting the grinding wheel body 203. Through the provided protection mechanism 3, the grinding wheel body 203 can be shielded and protected, thereby reducing the danger during grinding work, and can also be adjusted according to the grinding object, thereby improving practicality.

[0019] See also Figure 1 to Figure 3 A grinding wheel frame of a grinding machine with a precision sliding bearing includes a placement plate 1, a grinding wheel mechanism 2 is arranged below the placement plate 1, a protection mechanism 3 is installed above the placement plate 1, and the protection mechanism 3 includes a protection frame 301. The protection frame 301 can shield the entire grinding wheel body 203, so as to prevent the high-speed rotating grinding wheel body 203 from being exposed to the outside.

[0020] A moving block 302 is fixedly connected to the back of the protective frame 301, and a threaded hole 303 is opened on the upper surface of the moving block 302. A motor 304 is installed on the upper surface of the placement plate 1. A threaded rod 305 is fixedly connected to the output end of the motor 304. The top of the threaded rod 305 passes through the threaded hole 303 and extends to the top of the moving block 302. The bottom of the protective mechanism 3 is connected to a limiting mechanism 4. The threaded rod 305 and the threaded hole 303 are threadedly connected to ensure that when the threaded rod 305 rotates, the moving block 302 slides on the threaded rod 305.

[0021] The grinding wheel mechanism 2 includes a through slot 201, a motor 202 is installed on the bottom surface of the placement plate 1, a grinding wheel body 203 is arranged inside the through slot 201, the output end of the motor 202 is connected to the front of the grinding wheel body 203, the grinding wheel body 203 is located inside the through slot 201, and does not contact the inner wall of the through slot 201. When the motor 202 is working, it will drive the grinding wheel body 203 to rotate at a high speed, and will drive the grinding wheel body 203 to perform grinding work.

[0022] The limiting mechanism 4 includes two through holes 401 opened on the upper surface of the placement plate 1, and a limiting rod 402 is arranged inside each through hole 401. The top end of each limiting rod 402 is fixedly connected to the bottom surface of the protection frame 301, and the bottom end of each limiting rod 402 is fixedly connected to the limiting plate 403. The limiting rod 402 cooperates with the through hole 401 to fix the protection frame 301 to prevent it from deflecting, and the limiting rod 402 will be driven to slide when the protection frame 301 is raised or lowered, and the limiting plate 403 can limit the limiting rod 402 to prevent it from leaving the placement plate 1.

[0023] Two sets of legs 5 are fixedly connected to the bottom surface of the placement plate 1, and a protective box 6 is installed on the bottom surface of the placement plate 1 through two sets of bolts. The two sets of legs 5 are respectively located at the four corners of the placement plate 1, which can form a stable supporting state for the placement plate 1. At the same time, the protective box 6 can protect the motor 202.

[0024] A lifting groove 7 is provided on the upper surface of the placement plate 1, and the bottom end of the protection frame 301 passes through the lifting groove 7 and extends to the bottom of the placement plate 1. The bottom of the protection frame 301 can pass through the lifting groove 7 to the bottom of the placement plate 1 without affecting the lifting and lowering of the protection frame 301.

[0025] Working principle: When in use, the position of the protective frame 301 can be adjusted according to the size of the object to be polished, and the motor 304 can be started. The motor 304 will drive the threaded rod 305 to rotate inside the threaded hole 303, and the moving block 302 will slide on the threaded rod 305. At the same time, the moving block 302 will drive the protective frame 301 to rise and fall, and then start the motor 202 to drive the grinding wheel body 203 to rotate, and then place the object to be polished on the placement plate 1 for polishing. The protective frame 301 will shield the grinding wheel body 203 to reduce the danger during polishing.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
