Full-automatic metal tube detection device

Abstract

The invention discloses a full-automatic metal tube detection device which comprises an inner extension tube, a base, rotating shafts, movable arms, a fixed frame, a roll base, a ball, orbit grooves, detection needle bases, detection needles, a metal sheet fixing seat, metal sheets, a rubber band, a wire, a battery, a closed metal clamp, a battery box and an indicator light, wherein the base is arranged on the inner extension tube; the left side and right side of the base are connected with the movable arms through the rotating shafts; the movable arms are connected with the fixing frame; the ball base is arranged in the fixed frame; the ball is arranged on the ball base; the orbit grooves are formed in the upper side and lower side of each movable arm; and the detection needle bases are arranged in the orbit grooves. The metal tube detection device is provided with the movable arms and the ball, and the smoothness of the internal part of the metal tube is detected through rolling of the ball in the metal tube; and when the internal part is not smooth, the ball displaces, the detection needles are connected with the metal sheets, the circuit is closed, and the indicator light lights up to indicate that the part is not smooth. Furthermore, the device is simple in structure and convenient and accurate to use.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a fully automatic metal pipe detection device. Background technique [0002] Metal pipes are widely used in life and production, and metal pipes have relatively high quality requirements during use, otherwise it is easy to cause safety hazards during use, so strict testing is required before metal pipes are put into use. We need to carry out factory inspection of metal pipes. The inspection tools used at this stage are relatively backward, and the inspection is not comprehensive enough. Especially, it is very inconvenient to inspect the flatness of the inner wall of the metal pipe. Cause damage to the metal pipe, and then cause potential safety hazards and property losses, for which we need to innovate the existing technology. Contents of the invention [0003] The purpose of the present invention is to provide a fully automatic metal pipe detection device to solve the probl...
