Numerical control lathe clamp for machining of thin-wall parts prone to deformation

Abstract

The invention relates to a numerical control lathe clamp for machining of thin-wall parts prone to deformation. The numerical control lathe clamp comprises a fixing plate and steering shafts. A positioning block is arranged in the position, close to the circle center, of the upper end face of the fixing plate, and a plurality of fixing blocks are evenly arranged on the lower end face of the fixing plate around the circle center. A cylindrical hole allowing the corresponding steering shaft to pass through is formed in the middle of each fixing block. A pulling plate is arranged below the fixing plate in parallel, and a pulling rod is vertically connected to the center of the lower end face of the pulling plate. The upper end of each steering shaft vertically penetrates through the pulling plate, the corresponding fixing block and the fixing plate and is connected with a pressing plate. A hexagon nut is fixedly installed at the lower end of the corresponding steering shaft, and the portion, located between the hexagon nut and the lower end face of the pulling plate, of the corresponding steering shaft is sleeved with a spring. A spiral rail is arranged on the side wall of the corresponding steering shaft, and a guiding screw is horizontally installed on the side wall of one end of the corresponding fixing block. One end of the guiding screw is embedded into the corresponding spiral rail, and the guiding screw slides along the corresponding spiral rail along with movement, in the corresponding cylindrical hole, of the corresponding steering shaft. The numerical control lathe clamp for machining of thin-wall parts prone to deformation has the characteristics that the phenomena of displacement, knife vibration and deformation do not occur in the process of machining, and positioning is accurate.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a numerical control lathe fixture used for processing thin-walled and deformable parts. 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 CNC lathe fixture for processing thin-walled and easily deformed parts, using positioning blocks and product guide pins to accurately position the product, and the processing size is stable, and the mechanical force is evenly converted into The elastic force drives the steering shaft...
