Abstract

The invention provides a long shaft part center adjustable quick clamping and machining device and an operation method thereof. The device comprises a chuck, a fixture and a force applying device. Thechuck is used for fixing one end of a shaft part. The fixture comprises two V-shaped rods used for clamping the other end of the shaft part. The V-shaped rods are fixedly connected through a spring.The tail ends of the V-shaped rods are provided with rolling wheels. The force applying device comprises a cam, a bevel push block and a driving motor. The two bevels of the bevel push block are arranged in an inverted-V shape. The upper end of the bevel push block is arranged in the space formed by connecting the spring and the V-shaped rods. The lower end of the bevel push block is connected with one side of the cam. The driving motor is arranged on the other side of the cam. The long shaft part center adjustable quick clamping and machining device provided by the invention can implement quick clamping and dynamic clamping and machining on different diameters of shaft parts, is fast and convenient to operate, firm in clamping, integrates the functions of centers and follow-rest devices during traditional shaft part machining, saves the cost and optimizes the machining process.

Description

technical field [0001] The invention belongs to the technical field of mechanical clamping and processing devices, in particular to a center-adjustable fast clamping processing device for long shaft parts, especially a device for clamping, supporting and processing elongated shaft parts with different curvature radii Adjustable center type quick clamping processing device for long shaft parts. The present invention also relates to a working method of the center-adjustable fast clamping processing device for long shaft parts. Background technique [0002] Long shaft parts are widely used in various mechanical equipment as the main parts for transmitting torque and motion. However, due to the slender characteristics of long-axis parts, they are easily affected by their own gravity, cutting force and cutting heat during cutting, resulting in deformation, which seriously affects the quality of the machined surface and dimensional accuracy. At present, the processing of long-ax...
