Description

Technical Field

[0001] The invention relates to the technical field of grinding fixture equipment, in particular to a grinding and positioning fixture for a V-shaped guide rail pair. Background Art

[0002] CNC grinding machines generally use steel "V"-shaped guide pairs. Due to long-term use, friction between the guide surface and the rolling elements causes serious wear of the guide pair and the rolling elements, which reduces the accuracy of the processed products.

[0003] When the guide rail surface of the V-shaped guide rail pair is worn, the maintenance cost of direct replacement is high. Under the existing technology, a grinding device is generally used to grind the V-shaped guide rail pair to make its surface smooth. However, when the V-shaped guide rail pair is ground, there is a lack of positioning fixtures that are applicable to different shapes. This makes the grinding operation of the V-shaped guide rail pair time-consuming and labor-intensive, and different positioning fixtures need to be replaced when clamping V-shaped guide rail pairs of different shapes. For this reason, we propose a grinding and positioning fixture for the V-shaped guide rail pair. Summary of the invention
