Problems solved by technology

The surface roughness Ra of the slender shaft is required to be in the range of 0.1~0.8. Since the length of the slender shaft is larger than the diameter, the slender shaft is easy to vibrate during the process of finishing the surface of the slender shaft. Jumping occurs, resulting in high roughness and high reject rate
In the field of machining, such dimensions as roundness 0.001mm, surface roughness Ra0.1mm, and shaft runout 0.01mm are difficult to achieve. As far as general processing technology is concerned, even if these dimensions are realized, it will also cause relatively large High scrap rate, currently it is impossible to straighten precision slender shafts with runout less than 0.01mm, high scrap rate and low production efficiency

Abstract

The invention discloses a straightening jig for machining for precise slender shafts. The straightening jig for machining for the precise slender shafts comprises a base, a slender shaft fixation device, a correction device and a detection device, wherein the slender shaft fixation device, the correction device and the detection device are installed above the base, and the slender shaft fixation device and the correction device are opposite. The straightening jig for machining for the precise slender shafts disclosed by the invention is capable of realizing straightening the accuracy to be less than 0.005mm, thus effectively solving the problem of ultra-small-range correction for the precise slender shaft, capable of realizing rapid straightening for the precise slender shafts with a jitter amplitude of greater than 0.005mm, thus reducing the defective percentage of the precise slender shafts, simple and fast to straighten, thus increasing production efficiency. The invention further discloses a method for machining precise slender shafts, thus mechanized production is realized for the precise slender shaft, and the defective percentage is low.

Description

technical field [0001] The invention relates to a jig and method for machining a precision slender shaft, belonging to the technical field of machining. Background technique [0002] Currently, slender shafts with a length-to-diameter ratio greater than 25 are widely used in industrial production. The surface roughness Ra of the slender shaft is required to be in the range of 0.1~0.8. Since the length of the slender shaft is larger than the diameter, the slender shaft is easy to vibrate during the process of finishing the surface of the slender shaft. Jumping occurs, resulting in high roughness and high reject rate. In the field of machining, dimensions such as roundness 0.001mm, surface roughness Ra0.1mm, and shaft runout 0.01mm are difficult to achieve. High scrap rate, currently it is impossible to straighten the precision slender shaft with runout less than 0.01mm, the scrap rate is high, and the production efficiency is low. Contents of the invention [0003] Purpo...
