According to the technical scheme, the special lathe for shaft part machining comprises a lathe bed, a guide rail, a first spindle box, a second spindle box, a machine frame, a first spindle, a second spindle and a first center, a second center, a first power motor, a second power motor, a knife rest mechanism and a centerless radial clamp, wherein the first spindle box, the guide rail and the knife rest mechanism are arranged on the lathe bed, a machine frame is arranged on the guide rail, and the second spindle box is arranged on the machine frame; the first power motor is arranged in the first spindle box, the first spindle is arranged at the output end of the first spindle box, and the first center and the centerless radial clamp are arranged on the first spindle; and the second power motor is arranged in the second spindle box, the second spindle is arranged at the output end of the second spindle box, and the second center is arranged on the second spindle. According to the special lathe for shaft part machining, the machined shaft part can be guaranteed to have good coaxiality and step surface perpendicularity.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a special lathe for machining shaft parts. Background technique [0002] Shaft parts are key components for torque transmission and rotational motion transmission of various mechanical equipment. Manufacturing and processing technology is the key to the reliability and design performance of mechanical equipment, and the machining accuracy of shaft parts has an important impact on the performance, efficiency and service life of corresponding mechanical equipment. Therefore, modern machinery and equipment have high requirements on the machining accuracy of shaft parts, especially in terms of coaxiality and verticality of the step surface. [0003] Traditional shaft parts are processed on a general-purpose CNC lathe. One end of the shaft is clamped by a three-jaw chuck, and the center of the other end of the shaft is placed on the top of the tailstock; during processing, the to...

AI Technical Summary

Problems solved by technology

This processing method will lead to uneven machining of the shaft, which will affect the coaxiality of the shaft parts and the verticality of the step surface, resulting in a reduction in the processing quality of the shaft parts and even defective products.
