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

The invention relates to a bolt tightening device, in particular to a torque controlled multi-axis bolt tightening machine. Including driving device, transmission case, intermediate shaft, torque limiter and tightening head, one end of the intermediate shaft is connected with the driving device, and the other end is passed through the transmission case; the output of the transmission case has a transmission shaft, and each transmission shaft passes through the torque limiter An output shaft is connected, the other end of the output shaft is provided with a fixing plate, the output shaft at this end passes through the fixing plate and is connected with one end of the cardan shaft, the other end of the cardan shaft is connected with a template, and the tightening head is passed through by the template and connected with one end of the cardan shaft. Cardan shaft connection; a limit switch is installed on the template, and one side of the limit switch is provided with a sensor fixed on the template. The invention has the advantages of high efficiency, simple structure, high integration degree, etc., can realize multiple functions such as forward and reverse rotation, torque magnitude control, speed speed adjustment, etc., has strong adaptability and wide application range.
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...
