Auxiliary guide sleeve synchronous clamping and rotating structure applied to shaft machining

Abstract

The invention discloses an auxiliary guide sleeve synchronous clamping and rotating structure applied to shaft machining, which comprises a gantry support, a movable base assembly is arranged on the gantry support, a first rotating guide sleeve assembly is arranged on the movable base assembly, the gantry support is provided with a second rotating guide sleeve assembly which is coaxial with the first rotating guide sleeve assembly and is arranged in a front-back spaced mode, and a synchronous spline transmission assembly capable of keeping synchronous rotation in the moving process in the same axis direction is arranged between the first rotating guide sleeve assembly and the second rotating guide sleeve assembly. Synchronous clamping and synchronous rotation of the front end and the rear end of a shaft can be achieved, the torque in the transmission process is reduced, swing of the shaft in the rotation process is reduced, the complexity that the front end and the rear end need to be manually clamped traditionally is reduced through synchronous clamping, operation is more convenient, and meanwhile the size of a lathe shaft installation base can be freely adjusted according to the length of the shaft, so that different shafts can be machined.

Description

technical field [0001] The invention relates to a lathe shaft mounting seat, in particular to an auxiliary guide sleeve synchronous clamping and rotating structure applied to shaft processing. Background technique [0002] The lathe shaft mounting seat is used to install the strip-shaped shaft body and process the shaft body to assist the processing of the shaft body. Due to the compact structure of the existing shaft body mounting seat, the length of the processing lathe cannot be freely adjusted, and the comparison cannot be made. The long shaft body is processed, and if the shaft body is long and the rear end swings a lot during the rotation process, the rear end cannot realize synchronous rotation and clamping, and the torque is large, and the size of the lathe shaft body mounting seat cannot be freely adjusted according to the shaft body length. , poor adaptability. [0003] Therefore, the existing lathe shaft mounting seat needs to be further improved. Contents of t...
