Description

[0001] This utility model relates to the field of pipe fitting processing technology, and in particular to a pipe fitting processing error prevention device. Background Technology

[0002] In the field of pipe fittings processing, quality error prevention and inspection is a key link to ensure product accuracy and reliability. Traditional pipe fittings inspection devices mostly use a single error prevention and inspection method, such as measuring the outer diameter with mechanical calipers or using an endoscope for internal inspection. Although the improved inspection methods utilize automated inspection equipment, the function of the inspection equipment is limited, and it can only inspect one attribute at a time, which is inefficient.

[0003] Currently, Chinese patent CN220083948U discloses a pipe fitting size detection device, which includes an image detection module connected to a lifting adjustment module. The image detection module includes a camera and a display. The camera is surrounded by a supplementary lighting mechanism, and the display is configured to display image information, size information, and provide user input. A pipe fitting support module is located below the image detection module. The device also includes a control cabinet, which includes a control module and a storage module. The control module is electrically connected to the storage module and the image detection module. The storage module is used to store the data collected and processed by the control module.

[0004] This testing device avoids errors caused by pipe deformation due to operator hand-holding the pipe for measurement, as well as errors in reading and recording by the operator. The test results are more accurate, and the measurement data is easy to trace later. However, the testing items of this device are not comprehensive, and it cannot fully play the role of error prevention testing for pipes. Summary of the Invention

The first scanner and the second scanner are respectively disposed at both ends of the first detection opening, and the third scanner is disposed directly above the first detection opening. The first scanner, the second scanner, and the third scanner form a three-way scanning.

[0009] Furthermore, the pipe fitting outer diameter measuring module includes a first measuring element and a second measuring element.

[0011] Furthermore, the lower ends of the first and second scanners are provided with scanner bases, and the lower end of the third scanner is provided with a scanner bracket, which is fixedly mounted on the upper end of the error-proofing detection platform.

The servo track is disposed on the upper end of the error-proofing detection platform, the adjusting slider slides along the servo track, the connecting block is disposed on the upper end of the adjusting slider, and the pipe fitting clamping plate is disposed on the lower end of the connecting block. The end face of the measuring reference plate and the end face of the pipe fitting clamping plate are on the same longitudinal horizontal plane, and the emitting end face of the laser rangefinder and the end face of the pipe fitting clamping plate are on the same longitudinal horizontal plane.

An installation slot is provided at the upper end of the error-proofing testing platform 1, and the installation slot is located at the center of the error-proofing testing platform 1. Inside the installation slot is a guide tube 2 that is fixedly connected to the error-proofing testing platform 1. The guide tube 2 provides the positioning and guiding functions for the fittings.

[0026] The upper end of the guide tube 2 is provided with a first detection opening 3, a second detection opening 4, and a third detection opening 5 from right to left. The upper end of the error-proof detection platform 1 is provided with an internal scanning module for the pipe fitting at the position corresponding to the first detection opening 3.

The upper end of the error-proof detection platform 1 is provided with an external image capture module for the pipe fitting at the position corresponding to the third detection opening 5. When the pipe fitting enters the interior of the guide tube 2, the guide tube 2 is fixed by the mounting groove at the center position. The pipe fitting moves along the guide tube 2 to different detection openings, triggering the detection of the corresponding module.

[0027] The internal scanning module of the pipe includes a first scanner 601, a second scanner 602 and a third scanner 603. The first scanner 601 and the second scanner 602 are respectively disposed at both ends of the first detection opening 3, and the third scanner 603 is disposed directly above the first detection opening 3. The first scanner 601, the second scanner 602 and the third scanner 603 form a three-way scanning.

[0028] Furthermore, the lower ends of the first scanner 601 and the second scanner 602 are provided with scanner bases 604, and the lower end of the third scanner 603 is provided with a scanner bracket 605. The scanner bracket 605 is fixedly installed on the upper end of the error-proofing detection platform 1.

[0029] The internal scanning module of the pipe fitting is used to detect the internal structure of the pipe fitting, such as wall thickness and internal defects. The first scanner 601 and the second scanner 602 are located at both ends of the first detection opening 3 and scan the inside of the pipe fitting horizontally. The third scanner 603 is located directly above the pipe fitting and scans the pipe fitting vertically. The three-dimensional scanning forms three-dimensional data, covering the inner surface of the pipe fitting. Multi-angle detection ensures that no internal defects are missed and improves the comprehensiveness of the detection.

The end face of the measuring reference plate and the end face of the pipe fitting clamping plate 706 are on the same longitudinal horizontal plane. The emitting end face of the laser rangefinder 702 and the end face of the pipe fitting clamping plate 706 are on the same longitudinal horizontal plane.

[0032] The pipe fitting outer diameter measuring module is used to accurately measure the outer diameter of the pipe fitting. The first measuring component contacts the pipe fitting clamping plate 706 through the measuring reference plate to determine the fixed reference. The second measuring component emits a laser to the surface of the measuring reference plate through the laser rangefinder 702. Combined with the servo rail 703 to adjust the position of the slider 704, the pipe fitting clamping plate 706 abuts against the outer wall of the pipe fitting to realize the function of dynamic measurement of the outer diameter.

[0033] The external image capture module for pipe fittings includes an industrial camera 801 and a camera bracket 802. The camera bracket 802 is fixedly installed on the upper end of the error-proof inspection platform 1. The industrial camera 801 is embedded and fixed in the camera bracket 802. The external image capture module for pipe fittings detects external defects such as scratches and deformations through visual inspection.
