[0028] The positioning member 3 is provided with a plurality of positioning blocks 31, which are used to be inserted into the mounting holes of the linear guide rail in sequence, so as to ensure that the relative position of the positioning member 3 and the linear guide rail is accurate;

[0029] The grinding component 4 includes a grinding rod 5 and a tensioning member 6, and the grinding rod 5 is movably connected to the mounting plate 1 through the tensioning member 6 to ensure that the grinding rod 5 keeps in contact with the side of the linear guide rail;

[0030] The detection component 7 includes a reading head 10 and a grating ruler 11. The power component 2, the reading head 10 and the grating ruler 11 are all electrically connected to an external control system for controlling their operation and transmitting signals.

[0031] The positioning member 3 is specifically in the shape of a disc, the power member 2 is a motor for providing a rotational force, and the positioning block 31 is located on the side arc surface of the positioning member 3 .

[0032] The power member 2 is specifically a stepping motor, which is used to accurately provide rotational force. The positioning blocks 31 are evenly distributed on the side of the positioning member 3. The positioning blocks 31 are specifically cylindrical and are used to match the shape of the positioning holes of the linear guide rail.

[0033] The mounting plate at the end of the grinding rod 5 is movably connected to the mounting plate 1 through a tensioning member 6 , and the grinding rod 5 passes through the mounting plate 1 to ensure that the grinding rod 5 maintains contact with the linear guide rail between the two mounting members 1 .

[0034] The grinding rod 5 is symmetrical about the positioning member 3 , and is movably connected to the mounting plate 1 . The tensioning member 6 is an elastic element, and is in a stretched state, for pulling the grinding rod 5 to make it close to the two sides of the linear guide rail between the two mounting plates 1 .

Only when the readings of the two reading heads 10 are consistent, the grinding step can be started; then the power part 2 starts to work under the control of the external control system. During this process, the power part 2 drives the positioning part 3 to rotate at a constant speed, and the positioning blocks 31 on the positioning part 3 arrive at the mounting holes of the linear guide rail at a constant speed in turn, thereby driving the grinding rod 5 on the mounting plate 1 to move at a constant speed on the side of the linear guide rail. During this process, the grinding rod 5 grinds the side of the linear guide rail. During this process, the power part 2 drives the grinding rod 5 to make reciprocating motion on the side of the linear guide rail a certain number of times, thereby completing the grinding process of the side of the linear guide rail; repeat the above process until the work is completed.
