Abstract

The invention relates to a spiral steering clamp for a numerical control machine tool. The spiral steering clamp comprises a fixing plate and steering shafts. A positioning block is arranged at the position, close to the circle center, of the upper end face of the fixing plate. Multiple fixing blocks are evenly arranged at the positions, around the circle center, of the lower end face of the fixing plate. Cylindrical holes allowing the steering shafts to pass are formed in the middle portions of the fixing blocks. A pulling plate is arranged below the fixing plate in parallel. A pulling rod is vertically connected to the center of the lower end face of the pulling plate. The steering shafts vertically penetrate the pulling plate, the fixing blocks and the fixing plate from bottom to top. A pressing plate is installed at the upper ends, penetrating the fixing plate, of the steering shafts. Hexagon nuts are fixedly installed at the lower ends of the steering shafts. The portions, between the hexagon nuts and the lower end face of the pulling plate, of the steering shafts are sleeved with springs. Spiral rails are arranged on the side walls of the steering shafts. A guiding screw is horizontally installed on the side wall of one end of each fixing block. One ends of the guiding screws are embedded into the spiral rails and slide along the spiral rails along with movement of the steering shafts in the cylindrical holes. The spiral steering clamp has the beneficial effects that no displacement or tool vibration or deformation is generated in the machining process, and positioning is accurate.

Description

technical field

[0001] The invention relates to the technical field of clamps, in particular to a screw steering clamp for a numerically controlled machine tool. Background technique

[0002] At present, most of the fixtures of CNC machine tools are prone to deformation after clamping thin-walled and deformable precision parts, and the parts often have displacement, vibration, and inaccurate positioning during the processing process. It is also more complicated, so it is necessary to optimize the existing CNC machine tool fixture structure for these phenomena. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a numerical control machine tool screw steering fixture, which has the characteristics of no displacement, no vibration of the knife, no deformation, and accurate positioning during the processing.

[0004] The technical solution adopted by the present invention to solve the technical problem is to provide a ...
