Problems solved by technology

[0002] The pipe length measuring device is usually used for the length counting and cutting of materials, that is, after measuring a certain length of pipe fittings, it is cut off. The common pipe length measuring device generally uses a stepping motor or a servo motor as the power source, and then uses two rollers The wheel drives the pipe to move, and then calculates the length of the pipe according to the number of rotations of the motor and other data. However, this method of length measurement has two disadvantages. First, sliding friction is prone to occur between the material and the roller, which affects the accuracy of the length measurement. Second, For some materials with strong ductility, after being squeezed by two rollers, the length will increase, resulting in a difference between the actual length of the material and the measured length, and the measurement is inaccurate

Abstract

The invention discloses a pipe fitting length measuring device, which comprises a rack, a length measuring assembly, a conveying assembly and a controller, wherein the length measuring assembly is arranged on the rack, the length measuring assembly is used for converting a displacement signal of a measured pipe fitting into an electric signal, and the conveying assembly is arranged on the rack; the conveying assembly comprises an upper roller set and a lower roller set, the upper roller set and the lower roller set are arranged at intervals in the vertical direction, the upper roller set and the lower roller set are used for clamping a measured pipe fitting and conveying the measured pipe fitting to the length measuring assembly, and the controller is connected with the length measuring assembly. According to the pipe fitting length measuring device provided by the embodiment of the invention, by adopting a layout mode that the driving component is arranged in front of the length measuring component, the influence on length measuring precision caused by sliding friction between the material and the roller is reduced, so that the length measuring precision is high and stable, and the device has obvious advantages especially when the length-measured material has ductility.
