Thread detection, imaging and identification device

Abstract

The invention discloses a thread detection, imaging and identification device. The device comprises a clamping mechanism used for fixing a to-be-detected pipeline, a scanning imaging device which is located at the end of the to-be-detected pipeline and used for scanning threads of the to-be-detected pipeline, a mark coating device which is positioned between the clamping mechanism and the scanningimaging device, and a control module which is in communication connection with the clamping mechanism, the scanning imaging device and the mark coating device. According to the technical scheme, thescanning imaging device can achieve scanning forming of machined pipe threads, non-contact photoelectric scanning measurement is adopted, whether the threads meet the standard size or not is automatically detected, and whether products are qualified or not is judged; the measuring speed is high, the measuring precision is high, the size of a complex surface can be obtained in an extremely short time, and the defects that a traditional thread measuring ring gauge is prone to abrasion, the measuring speed is low, the size cannot be measured digitally, and part of the size is limited by the structure and cannot be measured can be overcome.

Description

technical field [0001] The invention relates to the field of detection of mechanical parts, in particular to a thread detection, imaging and marking device. Background technique [0002] The braking system of railway vehicles uses compressed air as the power source, and there are a large number of pipe thread joints in the braking device; the leakage of the brake piping system causes vehicle failures, which affects driving safety. There are many lower pipe joints, which are concealed to a certain extent, and it is difficult to troubleshoot; the quality of the pipe thread at the main part of the pipe joint connection directly affects the air tightness of the braking system and the driving safety of the entire train of vehicles. [0003] The existing patent CN206824210U discloses a thread automatic detection device for components, including a feeding device and a thread detection platform. The feeding device is provided with a vibrating plate and a feeding track. The opening ...

Problems solved by technology

However, the detection of the thread in this patent is a contact detection, which will cause certain damage to the test piece

[0004] In summary, it is necessary to design a thread detection, imaging, and marking equipment to solve the defects of traditional thread measurement ring gauges such as easy wear, slow measurement speed, inability to measure dimensions digitally, and some dimensions cannot be measured due to structural limitations.
