Torque-control multishaft bolt tightening machine

Abstract

The invention relates to bolt tightening devices, in particular to a torque-control multishaft bolt tightening machine which comprises a driving device, a gear box, an intermediate shaft, torque limiters and a tightening head, wherein one end of the intermediate shaft is connected with the driving device, and the other end penetrates out of the gear box; the outputs of the gear box are provided with transmission shafts, each transmission shaft is connected with an output shaft through the torque limiter, the other end of each output shaft is provided with a fixed plate, the output shaft at the end is connected with one end of a universal shaft after penetrating through the fixed plate, the other end of the universal shaft is connected with a template, and the tightening head is connected with the universal shaft through the template; and the template is provided with a limit switch, and one side of the limit switch is provided with a sensor fixedly connected on the template. The invention has the advantages of high efficiency, simple structure, high integration level, strong adaptability, wide application range and the like, and can realize multiple functions of reverse rotation, control on magnitude of moment, speed regulation and the like.

Description

technical field [0001] The invention relates to a bolt tightening device, in particular to a torque controlled multi-axis bolt tightening machine. Background technique [0002] Generally, the assembly line has many equipments and complex technologies, and there are many types of tightening machine tools used, which can be roughly divided into three types: electric single-axis tightening machine, electric multi-axis tightening machine and pneumatic single-axis tightening machine. Most of the electric multi-axis tightening machine transmits power through the pulley; the electric single-axis tightening machine is composed of a rotor and a stator, and the workpiece is tightened through the rotation of the rotor; the pneumatic single-axis tightening machine rotates the impeller through the airflow. The protection of the tightening machine is achieved by reducing the pressure through the pressure relief valve. When the assembled workpieces are in the same working plane or close t...

AI Technical Summary

Problems solved by technology

When the assembled workpieces are in the same working plane or close to the same plane, and the number of bolts is large, if a single-axis tightening machine is used, the work efficiency will be very low, and the torque of the tightening head is controlled by people, which affects the accuracy of the workpiece. and quality, it is very inconvenient for workers to operate, and it increases the workload of workers, which seriously affects the work rhythm

In order not to affect the work progress, only increase the number of workers to make up for the lack of equipment functions, which will undoubtedly increase the production cost, and due to the increase in the number of workers, it will also make it difficult to manage and control
