Fixture for milling two surfaces of guide rail sliding block

The utility model provides a clamp for milling two surfaces of a guide rail sliding block, and belongs to the technical field of clamps matched with machine tools. Comprising a sliding block and a support, to-be-machined sliding blocks are mounted at the bottoms of the through cavities; the longitudinal section of the to-be-machined sliding block is in a right-angle U shape. The right-angle U-shaped side walls on the two sides of the to-be-machined sliding block are to-be-machined faces, the side wall connecting the two to-be-machined faces is an outer side face, and the outer side face is connected with the inner side wall of the through cavity in a clamped mode. A pressing block for supporting lifting is arranged at the top of the inner side of the through cavity and supports and downwards presses the to-be-machined sliding block; the milling machine is simple in structure, small in occupied space, capable of achieving series production and high in milling efficiency. 本实用新型提供一种铣导轨滑块两面的夹具，属于机床配套用夹具技术领域；包括滑块和
