Zusammenfassung: | The utility model discloses a fixture for an optical contour grinder. The fixture comprises a base, a lining, a chuck, a lead screw and a handle. A guide rail is arranged on the base. The lining and the chuck are located on the two sides of the base respectively. The lining is fixedly connected with the base. The chuck comprises a fixed block and a movable block. Both the fixed block and the movable block are provided with clamping openings. The fixed block is fixedly connected with the base. The movable block is movably connected with the base through the guide rail. A threaded hole is formed in the lining. The two sides of the fixed block are fixedly and detachably connected with stop blocks respectively. The depth of parallelism between the upper surfaces of the stop blocks and the horizontal plane is 0.05 mm. The depth of parallelism between the upper surface of the clamping opening in the fixed block and the upper surface of the clamping opening in the movable block is 0.05 mm. When the fixture is used, only the height of a work table needs to be adjusted when the first part is clamped, subsequent parts only need to be clamped to the work table through the fixture and machining can be conducted directly, the situation that the up-down height of the work table needs to be adjusted each time one part is machined is avoided, time is saved, and work efficiency is improved. |
