Non-contact internal thread detection device

Abstract

The invention provides a non-contact internal thread detection device, which belongs to the technical field of internal thread detection, and comprises a reflector, a spectrum confocal sensor and a rotating assembly; the rotating assembly comprises a connecting sleeve, a connecting pipe, a fixing frame, a rotating mechanism, a front guide plate, a rear guide plate, a cable guide block and a cable winding cylinder; the fixing frame comprises a front end plate, a rear end plate and a connecting plate, and a cable port is formed in the rear end plate; the front end of the connecting sleeve is provided with a reflector, the rear end is fixedly connected with the front end of the connecting pipe, and the side wall is provided with a light outlet; the connecting pipe rotationally penetrates through the front end plate and is driven by a rotating mechanism to rotate, and the rear end is fixedly sleeved with the front guide plate; the rear guide plate is connected with the front guide plate through a connecting piece; the cable guide block is fixed on the rear side of the rear guide plate; the cable winding cylinder is located between the rear guide plate and the rear end plate, and the rear end of the cable winding cylinder is fixed to the rear end plate. According to the invention, automatic and non-contact detection of internal threads can be realized, and the detection precision and the detection speed are improved.

Description

technical field [0001] The invention belongs to the technical field of internal thread detection, and specifically discloses a non-contact internal thread detection device. Background technique [0002] Internal threads are widely used in the machinery industry. The main purpose is fastening, sealing, power transmission and displacement. Its manufacturing level plays a vital role in the reliability, working performance and even normal function of the connection of mechanical parts. Due to the complex shape of the internal structure of the internal thread, the internal space is relatively small, manual inspection requires a lot of manpower and material resources, and the inspection results are subject to subjective influence and are not accurate enough. Contact detection may also cause wear or damage to the product, further affecting the detection accuracy.
