Adjustable multishaft screwing mechanism

Abstract

The invention discloses an adjustable multishaft screwing mechanism, which comprises angle adjusting mechanisms, radial adjusting mechanisms, single-shaft screwing machines, a frame and a driving control unit, wherein the angle adjusting mechanisms are fixed on the upper disc of the frame, the radial adjusting mechanisms are installed on a lower disc, adjusting link rods are used for connecting the angle adjusting mechanisms with the corresponding radial adjusting mechanisms, the single-shaft screwing machines are installed on the radial adjusting mechanisms, and the driving control unit is installed on the top cover of the frame. By adopting the invention, the screwing speeds, moments and directions of different single-shaft screwing machines are controlled; and the adjustable multishaft screwing mechanism disclosed by the invention has the advantages of high regulation precision, simple structure, convenience for adjusting and the like, and can realize rapid screwing of bolts at different positions.

Description

technical field [0001] The invention relates to a multi-axis bolt tightening device, in particular to a multi-axis tightening mechanism capable of accurately adjusting the orientation of a tightening head. Background technique [0002] In order to ensure the assembly quality and overall performance of high-precision equipment, it is necessary to accurately control the torque and tightening sequence of important bolts and nuts during the assembly process. However, the traditional manual tightening method is very random, and it is difficult to accurately tighten the tightening process. controlled and inefficient. For this reason, a large number of single-spindle tightening machines and multi-spindle tightening machines are used in the assembly process. [0003] The single-axis tightening machine is operated by workers, and the alignment of the tightening head, the magnitude of the torque, and the tightening sequence are all controlled by humans. Errors and leaks are inevitabl...

AI Technical Summary

Problems solved by technology

[0003] The single-axis tightening machine is operated by workers, and the alignment of the tightening head, the magnitude of the torque, and the tightening sequence are all controlled by humans. Errors and leaks are inevitable, and precise control cannot be achieved to ensure assembly quality and performance.

When the number of bolts is large, the assembly efficiency is low and the labor intensity of workers is high

The position of the tightening head of the multi-axis tightening machine is mostly fixed, and the purpose is single. Once the bolt position changes during the assembly process, it is necessary to re-purchase the multi-axis tightening equipment, and the price of the multi-axis tightening equipment is generally relatively high, which will greatly increase the cost. necessary waste

For a small number of multi-axis tightening equipment, although it can be adjusted, the adjustment range is small, or only the distance or angle can be adjusted, and the self-adjustment structure is complicated, the manufacturing cost is high, and the fabrication is inconvenient, and the precise adjustment of angle and distance cannot be realized.
