[0002] As a key component in machining and automated production lines, linear guides' precision and reliability directly impact the performance of the entire mechanical system. Guide rails are typically manufactured through a one-time machining process, followed by secondary processing. For example, these are drilled with locating holes, which are then inserted into the base to secure the rail. Finally, the rail surface is polished to reduce friction.

[0003] In the prior art, the side surface of the guide rail is not flat, but has flat surfaces and curved surfaces. To facilitate grinding, a grinding tape is usually wrapped around the guide rail, and then the guide rail is moved and ground. For the inwardly concave portion of the guide rail surface, a clamping component such as a clamping wheel needs to be provided. However, the position of the clamping component of the existing grinder is fixed. For guide rails of different sizes and different inwardly concave positions, the grinder needs to be replaced or the position of the clamping component needs to be set separately, which not only increases the work intensity but also reduces efficiency.

[0031] The pressing roller 31 is pushed against the grinding belt 102 at the concave position of the guide rail 101 by the push cylinder 32 of the clamping assembly 3, and the position of the clamping assembly 3 is adjusted by the sliding part 2. It is applicable to guide rails 101 of different sizes and different concave positions. The adjustment is simple and convenient, saving time and effort, reducing work intensity and improving efficiency.

[0032] like Figure 3 As shown, the connecting portion 35 includes a first support plate 351, a second support plate 352, a connecting rod 353, and a sliding post 354. The first support plate 351 is connected to the output end of the push cylinder 32. The connecting rod 353 is connected to the pressure roller 31 at one end and to the second support plate 352 at the other end. The first support plate 351 and the second support plate 352 are arranged opposite each other. The sliding post 354 is slidably connected to the first support plate 351 at one end and to the second support plate 352 at the other end. A compression spring 355 is provided between the first support plate 351 and the second support plate 352.
