Single-axis yaw electric bolt tightening machine

Abstract

The invention discloses a single-axis yaw electric bolt tightening machine, which comprises a base, a bracket, a revolving servo motor, an encoder, an output revolving shaft, a small belt wheel, a cog belt, a large belt wheel, a revolving shaft, a swiveling jib, a shaft sleeve, a guide post, a housing plate bracket, an electric tightening shaft assembly, a sleeve, a counterforce support plate, a special sleeve, a counterforce sleeve, a servo motor, a torque sensor, an angle sensor and a connecting shaft, wherein the bracket is fixed on the base, and is provided with the revolving servo motor and the encoder; the revolving servo motor is connected with the output revolving shaft; the output revolving shaft is provided with the small belt wheel; the small belt wheel is matched with the large belt wheel through the cog belt; the large belt wheel is connected with the revolving shaft; the guide post is connected with the swiveling jib through the shaft sleeve, and is fixed on the housing plate bracket; and the electric tightening shaft assembly is fixed in the housing plate bracket.

Description

technical field [0001] The invention relates to the field of installation equipment for wind power generators, in particular to a single-axis yaw electric bolt tightening machine. Background technique [0002] At present, in the assembly and production of yaw devices in various large-scale wind power manufacturing enterprises, pneumatic wrench, hydraulic wrench and other tightening tools are generally used to tighten the bolts on the yaw device during the bolt tightening process. There are problems such as high noise, large vibration, inconvenient operation, high labor cost, inability to guarantee the torque accuracy of the tightened bolts and deformation of yaw parts, and more importantly, it is difficult to ensure the assembly quality. For example, in terms of noise, the noise of the pneumatic wrench is above 90DB, and the noise of the hydraulic wrench is above 80DB. In terms of torque accuracy, the torque error of the pneumatic wrench is about 30%, and that of the hydraul...
