Tool device for improving slender shaft machining precision and method

Abstract

The invention discloses a tool device for improving the slender shaft machining precision, and relates to the technical field of slender shaft machining, the tool device comprises a bottom plate and abase fixedly connected to the top of the bottom plate through supporting legs, a fixing groove is formed inside the base, a supporting seat is fixedly connected to the top of the bottom plate, a grinding assembly and a driving assembly are arranged at the top of the supporting seat, a limiting supporting assembly is arranged at the top of the base, the limiting supporting assembly comprises a sliding plate, a first electric push rod and a movable plate, the bottom of the sliding plate is slidably connected with one side of the top of the base, and one side of the sliding plate is in threadedconnection with a protective cover. According to the tool device for improving the slender shaft machining precision and a method, a slender shaft can be pushed and fed, the two ends of a shaft body are both supported and limited, the phenomenon that the shaft body is prone to vibration during polishing work can be prevented, and therefore the polishing precision of the slender shaft is guaranteed, and the actual use condition is met.

Description

technical field [0001] The invention relates to the technical field of slender shaft machining, in particular to a tool device and method for improving the machining accuracy of a slender shaft. Background technique [0002] A shaft whose length to diameter ratio is greater than 25 (ie L / D>25) is called a slender shaft, such as a screw on a lathe, a light rod, etc., due to the poor rigidity of the slender shaft, it is subjected to cutting force and cutting heat during turning. Due to the influence and influence of vibration and vibration, it is easy to produce deformation, processing errors such as straightness and cylindricity, and it is difficult to meet the technical requirements of shape and position accuracy and surface quality on the pattern, making cutting processing very difficult. The larger the L / d value , the turning process is more difficult. [0003] At present, when grinding the surface of the slender shaft, since the grinding device is not provided with a ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a tool device and method for improving the machining accuracy of the slender shaft, which solves the problem that the grinding device does not have a stable anti-vibration support structure, and the slender shaft itself has a slender workpiece. And the feature of poor rigidity, in the process of grinding the surface of one end, the stability of the other end is not enough, so it is prone to obvious vibration, resulting in the problem of low grinding accuracy and poor quality of the shaft surface
