Abstract
The invention relates to a twin-shaft pitch electric bolt screwing machine, comprising a substrate front end, a substrate back end, a servomotor, a servo revolving table, a servo feeding sliding table, a pneumatic device, a main machine base, a lifter, a lift adjusting guide post, a support upright post, a lifting platform, an angular adjuster, a bearing platform, a revolving servomotor, an output rotating shaft, a centering device, a rotating arm, a sliding lead screw, a screwing servomotor and an automatic nut fitting and counterforce device. The low-noise vibration-free full automatic twin-shaft pitch electric bolt screwing machine has the advantages of simplicity of operation, high screwing accuracy and equalized pressing force, can remember the position of a rejected product, simultaneously performs screwing operation on diagonal bolts on a pitch instrument, saves time and labor, ensures the installation accuracy of the pitch instrument, and can not cause deformation of the pitch instrument.
Description
technical field [0001] The invention relates to the field of electric bolt tightening machines, in particular to a biaxial variable pitch electric bolt tightening machine. Background technique [0002] With the continuous development of industry, energy problems are becoming more and more serious. Renewable energy has become the focus of people's attention. Wind energy is a kind of green and renewable energy. The corresponding wind power generation has become the focus of people's attention. necessary equipment. At present, major manufacturers of wind power pitch control instruments use pneumatic wrench, hydraulic wrench, etc. to tighten and assemble the bolts of the pitch control instrument. The partial deformation of the pitch indicator causes waste of labor costs. Contents of the invention [0003] In view of the defects in the existing products, the present invention provides a two-axis variable-pitch electric bolt tightening machine. [0004] In order to achieve th...
