Quantitative numerical-control string winding machine

Abstract

The invention relates to the technical field of accessory devices for string machining, in particular to a quantitative numerical-control string winding machine. The machine comprises a machine body frame, a left string core driving mechanism, a right string core driving mechanism and a string core tensioning mechanism; the string core tensioning mechanism comprises a tensioning sliding table and a first servo motor, the output end of the first servo motor is provided with a driving belt for driving the tensioning sliding table to move transversely, the right string core driving mechanism is connected with a tension sensor, a transverse moving sliding table mechanism is arranged at the top of the machine body frame, an external winding and unwinding mechanism, a wire stabilizing mechanism and a grinding mechanism are mounted on the transverse moving sliding table mechanism, the wire stabilizing mechanism comprises a first telescopic air cylinder, a first mounting frame and a first wire guide wheel, and the grinding mechanism comprises a second telescopic air cylinder, a second mounting frame, a clamping manipulator, a second servo motor and a grinding block. Grinding treatment is automatically carried out according to string technological setting, and a winding wire is stably transmitted to a string core through a damping pulley, so that the uniformity and compactness of the winding wire are ensured, the quality of the string is ensured, and the practicability is improved.

Description

technical field [0001] The invention relates to the technical field of string processing attachments, in particular to a numerically controlled string winding machine. Background technique [0002] It is well known that strings, such as those of a lute or a violin, generally include a steel string core (hereinafter referred to as the string core) and a wire wrapped around the string core. During the production of the strings, both ends of the string core need to be tensioned and fixed to form a certain axial pretension, and then the winding wire is wound around the outside of the string core along the length direction. According to needs, the wire winding may be formed from different types of wires (metal and / or non-metal) after multiple winding processes. When winding, it rotates at a certain speed by rotating the fixed parts at both ends of the string core, and then winds the winding wire to the outside of the string core. [0003] The traditional string winding machine ...

AI Technical Summary

Problems solved by technology

[0003] The traditional string winding machine fixes the two ends of the string core, manually wraps the winding wire on one end of the string core for fixing, and then drives the string core to rotate at high speed synchronously through the motors at both ends, and at the same time moves the winding wire, so that the winding wire Wound on the string core, the work efficiency is low, and the pretension of the winding wire cannot be controlled manually and the tension of the winding wire is at a constant value, which makes the pretension of different strings or different positions of the same string different, which affects the quality of the strings
