Technical Field

[0001] The utility model relates to the technical field of pipe fitting detection, in particular to a pipe fitting detection device. Background Technique

[0002] In the production process of existing pipe fittings, visual inspection needs to be carried out on both ends of the pipe fittings. The visual inspection device takes pictures of both ends of the pipe fittings for inspection, and obtains the appearance images of both ends of the pipe fittings through the visual inspection device and detects whether there are obvious deformation, scratches and other appearance defects at both ends of the pipe fittings.

[0003] Among them, when carrying out visual inspection on both ends of the pipe fitting, the operator needs to first fix the pipe fitting on the fixture of the inspection device and align one end of the pipe fitting with the visual inspection device, and carry out visual inspection on one end of the pipe fitting through the visual inspection device; after one end of the pipe fitting is inspected, the operator horizontally rotates the pipe fitting 180 degrees, then aligns the other end of the pipe fitting with the visual inspection device, and carries out visual inspection on the other end of the pipe fitting through the visual inspection device.

[0004] In the existing detection method, when one end of the pipe fitting is detected, it is necessary to manually rotate the direction of the pipe fitting and detect the other end of the pipe fitting, and the detection process is relatively troublesome. Summary of the Invention

[0012] Preferably, a fixing frame is provided at one end of the moving device away from the vision detection device, and the dimension detection device and the second rotation driving device are arranged on the fixing frame.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0018] As Figures 1 to 2 shown, a pipe fitting detection device includes a moving device 1, a moving seat 2 is arranged on the moving device 1, a first rotation driving device 4 is arranged on the moving seat 2, a clamping jaw 5 for clamping the pipe fitting 10 is connected to the first rotation driving device 4, and the first rotation driving device 4 drives the clamping jaw 5 to rotate around the vertical axis.

[0019] A vision detection device 7 is arranged at one end of the moving device 1, and a dimension detection device and a second rotation driving device 9 are arranged at the other end of the moving device. Among them, a fixing frame 6 is provided at one end of the moving device 1 away from the vision detection device 7, and the second rotation driving device 9 is arranged on the fixing frame 6. A dimension detection device and an angle-adjusting clamping jaw are connected to the second rotation driving device 9, and the second rotation driving device 9 drives the angle-adjusting clamping jaw to rotate around the horizontal axis.

[0020] Among them, the moving device 1 is an electric guide rail. The moving device 1 drives the moving seat 2 to move linearly.

[0021] In this embodiment, the first rotation driving device 4 is a rotary cylinder, and the second rotation driving device 9 is a servo motor. The gripper 5 and the angle adjustment gripper are both cylinder grippers 5.

[0022] On one side of the moving device 1, there is a temporary storage rack 3 for placing the calibration rod. The upper end of the temporary storage rack 3 is provided with a V-shaped positioning groove. The calibration rod is temporarily stored on the temporary storage rack 3. Before the dimension detection device performs detection, it is necessary to calibrate the dimension detection device with the calibration rod.

[0023] Further, at one end of the moving device 1 close to the vision detection device 7, there is an annular supplementary light 8, and the annular supplementary light 8 is located in front of the vision detection device 7. When performing vision detection on the end of the pipe fitting 10, the annular supplementary light 8 illuminates the detected end of the pipe fitting 10, improving the clarity of the image obtained by the vision detection device 7.

[0024] The vision detection device 7 used in this application is a prior art. The vision detection device 7 is used to detect whether there are defects such as cracks at the end of the pipe fitting.

[0025] The dimension detection device used in this application adopts the prior art. The dimension detection device is used to measure the end dimension (such as the pipe diameter) of the pipe fitting 10. For the specific structure and principle of the dimension detection device, reference can be made to the invention patent with the publication number CN113798209A and the invention title of an automatic pipe fitting head dimension detection device.

[0026] When the detection device detects the pipe fitting 10, the pipe fitting 10 is clamped on the gripper 5. The second rotation device drives the pipe fitting 10 to rotate so that one end of the pipe fitting 10 is aligned with the angle adjustment gripper. Then, the moving device 1 drives the pipe fitting 10 to move and the angle adjustment gripper clamps one end of the pipe fitting 10. Subsequently, the gripper 5 releases the pipe fitting 10, and the second rotation driving device 9 drives the pipe fitting 10 to rotate 360° around its own central axis. During the rotation of the pipe fitting 10, the vision detection device 7 performs vision detection on the end of the pipe fitting 10 that is directly opposite to the vision detection device 7; at the same time, the other end of the pipe fitting is directly opposite to the dimension detection device, and the dimension detection device detects the end dimension of the pipe fitting;

[0027] After one end of the pipe fitting 10 is detected, the angle adjustment jaw releases the pipe fitting 10, and the moving device 1 drives the pipe fitting 10 to move so that the end of the pipe fitting 10 exits from the angle adjustment jaw; then the second rotating cylinder drives the pipe fitting 10 to rotate 180 degrees in the horizontal direction and aligns the other end of the pipe fitting 10 with the angle adjustment jaw. Next, the moving device 1 drives the pipe fitting 10 to move and makes the angle adjustment jaw clamp one end of the pipe fitting 10. Subsequently, the jaw 5 releases the pipe fitting 10, and the second rotation driving device 9 drives the pipe fitting 10 to rotate 360° around its own central axis. During the rotation of the pipe fitting 10, the visual inspection device 7 performs visual inspection on one end of the pipe fitting 10 facing the visual inspection device 7; similarly, the dimensional inspection device inspects the dimensions of the end of the pipe fitting facing it.

[0028] After both ends of the pipe fitting 10 are detected, the angle adjustment jaw releases the pipe fitting 10, and the moving device 1 drives the pipe fitting 10 to move so that the end of the pipe fitting 10 exits from the angle adjustment jaw.

[0029] The utility model has the following advantages: When the device detects the pipe fitting 10, after one end of the pipe fitting 10 is detected, it can automatically turn the pipe fitting 10 horizontally by 180 degrees and detect the other end of the pipe fitting 10, without manually turning the direction of the pipe fitting 10 by hand, which facilitates the detection process and improves the detection efficiency.

[0030] The utility model is not limited to the above best implementation mode. Anyone can obtain other various forms of products under the inspiration of the utility model. However, no matter what changes are made in its shape or structure, as long as it has the same or similar technical solutions as this application, it falls within the protection scope of the utility model.
