Description

technical field [0001] The invention relates to the technical field of guitar production machinery, in particular to a guitar tuner torque testing machine. Background technique [0002] A guitar tuner is a device that adjusts the tension of the guitar strings to achieve guitar tuning, such as Figure 6 As shown, the guitar tuner includes a housing 2', a rotating column 2', and a tuning knob 3'. The rotating column 2' and the tuning knob 3' rotate through the housing 2', and the rotating column 2' is fixed with a turbine. The guitar tuner is fixedly connected with a worm, and the worm is engaged with the worm gear for transmission. On the rotating column 2', there is an opening 21' for guitar strings to pass through. If the torque of the tuning knob 3' is too large, the customer is using it Sometimes the experience is not good, and it is difficult to accurately fine-tune the tension of the guitar strings. After the production and assembly of the guitar tuners is completed, i...

[0002] A guitar tuner is a device that adjusts the tension of the guitar strings to achieve guitar tuning, such as Image 6 As shown, the guitar tuner includes a housing 2', a rotating column 2', and a tuning knob 3'. The rotating column 2' and the tuning knob 3' rotate through the housing 2', and the rotating column 2' is fixed with a turbine. The guitar tuner is fixedly connected with a worm, and the worm is engaged with the worm gear for transmission. On the rotating column 2', there is an opening 21' for guitar strings to pass through. If the torque of the tuning knob 3' is too large, the customer is using it The experience is not good, and it is difficult to accurately fine-tune the tension of the guitar strings

After the production and assembly of the guitar tuners is completed, it is necessary to test the torque of the tuners 3'. The current stage of the test is to pass the workers to dazzle the tuners 3' and feel the rotational torque resistance of the tuners 3'. This manual test First, the subjective feeling deviation is large, the torque size is judged by the workers, it is difficult to unify the standard, and the product quality is difficult to guarantee; second, it consumes a lot of labor, the detection efficiency is low, and the cost is high; the third is the clinker degree requirements of the workers. High, training is required in the early stage, and regular spot checks are required to check whether the product is qualified in the later stage, and the management cost is high
