AI Technical Summary

Technical Problem

In existing stringing machines, the tension/compression sensor and the racket string are not coaxial, which causes friction to affect the accuracy of tension detection. Furthermore, as the usage time increases, the friction increases, the compensation mechanism fails, and the actual tension value deviates from the expected value.

Method used

The device employs a combined structure of a wire clamping assembly, a sensor, a first slide, a support base, and a drive assembly. The sensor supports the wire clamping assembly, and the drive assembly adjusts the wire tension by sliding to reduce the influence of friction on the detection values. It also controls the tension stability through elastic buffering and a limit rod.

Benefits of technology

It effectively eliminates the influence of friction on tensile force detection, improves the accuracy and stability of tensile force detection, reduces sensor fluctuations, and extends the service life of the wire drawing machine.

Abstract

The utility model provides a wire drawing machine. The wire drawing machine comprises a wire clamping assembly; the sensor is used for detecting tension and supporting the wire clamping assembly; the first sliding seat is used for supporting the sensor; the supporting seat is used for supporting the first sliding seat in a sliding manner; and the driving assembly is used for driving the first sliding seat to move so as to adjust the tension of the stay wire, the driving assembly is installed on the supporting seat, and the power output end of the driving assembly is connected with the first sliding seat. According to the wire drawing machine, the wire clamping assembly is supported by the sensor, in the process that the first sliding base slides along the supporting base, the sensor is not affected by friction force between the first sliding base and the supporting base, and therefore the influence of abrasion between the first sliding base and the supporting base on a tension detection numerical value can be eliminated.
