Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe production, in particular to a metal pipe joint inner wall detection device. Background Art

[0002] A metal pipe is typically a tubular object made of metal used to transport liquids, gases, or solid particles. These pipes can be used in a variety of industrial, construction, and household applications. Different types and materials of metal pipes are selected based on specific needs and environmental conditions. Primary metal pipe materials include steel, copper, aluminum, and alloys. To increase the length of a metal pipe, two adjacent pipes must be connected together for installation. Therefore, during production, the inner walls of the joints must be inspected to assess surface finish and flatness for defects. This helps prevent safety issues such as loose joints, leaks, and breakage during use, ensuring the product's mechanical properties and service life.

[0003] However, the existing metal pipe joint inner wall detection device needs to loosen the fixing after inspecting the previous metal pipe, unload the material, and then reload and complete the fixing before the next inspection can be carried out. Continuous inspection cannot be achieved, the inspection process is cumbersome, and the inspection efficiency is low. Utility Model Content

[0007] A material receiving box is welded to one end of the discharge end of the conveyor belt at the bottom of the workbench. A material receiving plate is horizontally arranged in the material receiving box, and a spring is vertically welded between the bottom of the material receiving plate and the bottom of the material receiving box.

[0008] A fixing ring and a detector, wherein the fixing ring and the detector are respectively located above and on the side of the conveyor belt;

[0009] The driving mechanism is used to drive the fixing ring and the detector to move and drive the detector to rotate.

[0010] The metal tubes are placed in sequence between two adjacent rubber partitions on the conveyor belt, and the conveyor belt transports them, so as to facilitate subsequent continuous testing;

[0011] When the metal tube is inspected, the conveyor belt transports it forward to the top of the receiving box. Under the action of gravity, it falls to the top of the receiving plate inside the receiving box. The gravity and impact force drive the receiving plate to move downward and squeeze multiple springs. The springs buffer the impact force to prevent the metal tube from being damaged due to excessive impact during the unloading process.

[0012] As a further technical solution of the present invention, support legs are vertically welded at both corners of the bottom of the workbench, a controller is fixedly installed on one side of the top of the workbench, the top of the material receiving box is an open structure, and a side door is hinged on one side of the material receiving box.

[0016] When the metal pipe is transported to the detection position on the surface of the conveyor belt, the conveyor belt is stopped, and the electric telescopic rod is started to drive the fixed ring to descend until it fixes the top of the metal pipe to prevent it from moving during the detection process. At the same time, the electric telescopic rod drives the vertical rack to move downward through the connecting rod, and the vertical rack drives the first gear to rotate clockwise. The first gear drives the second gear to rotate clockwise through the connecting shaft, and the second gear drives the horizontal rack to move forward. The horizontal rack drives the vertical mounting plate to move forward. The vertical mounting plate drives the rotating motor and the detector fixed at its front end to move forward. When the fixed ring just fixes the metal pipe, the detector just moves forward. To the inside of the joint of the metal pipe, then start the rotating motor to drive the detector to rotate one circle to detect the inside of the joint of the metal pipe. After the detection is completed, start the electric telescopic rod to retract its telescopic end to loosen the fixation of the fixing ring and return the detector to its original position. The fixation of the metal pipe and the movement of the detector into place, the loosening of the metal pipe and the removal of the detector are all completed at the same time, making the detection process more streamlined; and after the detection of the previous metal pipe, it is only necessary to use the conveyor belt to transport the next metal pipe to the detection position for the next detection. There is no need to carry out the process of unloading and loading, which can realize continuous detection and improve the detection efficiency.

[0017] The beneficial effects of the present invention are as follows: the fixing of the metal tube and the movement of the detector into position, the loosening of the metal tube and the removal of the detector are all completed at the same time, which makes the detection process more streamlined; and after the detection of the previous metal tube, it is only necessary to use the conveyor belt to convey the next metal tube to the detection position for the next detection, without the need for manual unloading and loading processes, which can realize continuous detection and improve detection efficiency.
