Problems solved by technology

[0003] In addition to using a set of servo drive system, the servo tensioner now needs to cooperate with a mechanical structure composed of a spring tension rod as an important component. The spring tension rod in the mechanism is the main component that generates tension. Different tension requirements need to be selected and matched. Replacement of different spring tension rod specifications, because this design has problems such as various spring tension rod models and specifications, it is inconvenient to switch between different tension ranges, and switching between different tension ranges requires manual frequent replacement of spring tension rods. Increased manual operation work and use standard procedures; in addition, there are also great failures such as spring deformation and breakage caused by improper use or mismatching model specifications. In addition, the tension of the servo tensioner with the spring tension rod structure is Relying on the relative stretching of the spring and the tension rod to obtain the corresponding tension, this structural principle also has certain limitations in the parameters of the output tension range. When the tension parameter output needs to be larger, the spring tension rod also needs to be increased at the same time, infinite Increasing the spring tension will bring serious strength problems to the overall structure, and at the same time, the tension stability and cushioning sensitivity will decrease due to the infinite increase of the spring tension rod

Abstract

The invention relates to a high-torque servo tensioner which includes a mounting plate and a casing connected to the mounting plate. The mounting plate is provided with a wire feeding structure, a measurement structure and a shock absorption structure. The casing is provided with a display device. The wire feeding structure can perform active wire feeding, the measurement structure can be used formeasuring the tension of a wire in real time, the shock absorption structure can be used for reducing vibration at the wire exit position, and the display device can display a set tension upper limitvalue of the tensioner and display current real-time tension of the tensioner. By means of the high-torque servo tensioner, a spring tension rod structure is eliminated, and an active and passive bidirectional wire feeding system is realized; a servo motor is used for driving, meanwhile, a complete closed-loop control system is formed between a pressure sensor and the servo motor, and real-time feedback of tension output is realized; and the system can adjust the torque and speed of the motor through the set tension to keep the tension constant.

Description

technical field [0001] The invention relates to the technical field of servo tensioners, in particular to a servo tensioner without a spring tension rod.
