Technical Field

[0001] The utility model relates to the field of production equipment, in particular to the automatic production equipment for pipe fittings, and specifically to a bushing pressing system with a vision positioning system. Background Art

[0002] When installing a bushing on a hole of a pipe fitting, the traditional processing technology usually has the following problems:

[0003] 1. The relative positions of the fixed bushing and the pipe part are used for assembly without considering the position deviation of the installation hole on the pipe part, resulting in installation errors, which may cause poor bushing assembly, damage or damage to the bushing;

[0004] 2. The bushing pressing uses a cylinder or a hydraulic mechanism, lacking the flexibility suitable for various products, and the workload of product switching is large;

[0005] 3. When pressing in multiple bushings, they are pressed in one by one, with long working hours and high time costs. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the above defects and propose a vision positioning system, which is used to correct the installation position of the bushing, realize the automatic centering of the automatic bushing and the installation hole, and ensure the accurate installation of the bushing.

[0007] To achieve the above purpose, the utility model is realized as follows:

[0008] A bushing pressing system with a vision positioning system includes a pipe section clamping part, and bushing clamping parts arranged on both sides of the pipe section clamping part. The two pipe section clamping parts reciprocate along the X-axis direction through a first linear driving motor arranged in the X-axis direction, so as to press the bushings into both sides of the pipe section; the feature is that it further includes a vision positioning system, and the vision positioning system is used to monitor the deviation distance between the center lines of the bushing and the pipe section. When the monitored deviation distance between the center lines of the bushing and the pipe section meets the requirements, the two pipe section clamping parts reciprocate along the X-axis direction, so as to press the bushings into both sides of the pipe section.

[0009] For the above bushing pressing system with a vision positioning system, the bushing clamping part further includes a second linear driving motor and a third linear driving motor arranged on the Y-axis and Z-axis. The vision positioning system calculates the deviation distance between the center lines of the bushing and the pipe section, and when it is adjusted by the second linear driving motor and the third linear driving motor arranged on the Y-axis and Z-axis until the deviation distance between the center lines of the bushing and the pipe section meets the requirements, the two pipe section clamping parts reciprocate along the X-axis direction through the first linear driving motor, so as to press the bushings into both sides of the pipe section.

[0010] The above bushing pressing system with a visual positioning system, where the X-axis, Y-axis, and Z-axis refer to the three coordinate axes in the Cartesian coordinate system.

[0011] In the described bushing pressing system with a visual positioning system, the visual positioning system includes a camera, a lens, a light source, a display, a control handle or mouse, visual software, a controller, and connecting cables; under the illumination of the light source, the camera and lens are used to collect photos of the object to be photographed (i.e., the produced parts). The visual software compares the taken photos with a pre-set template in terms of pixels to identify information such as the size, color, and brightness of a certain feature of the part, thereby distinguishing the position of the object or determining the qualification of the item.

[0012] With the above design, the present utility model identifies the position deviations in two directions (Y-direction and Z-direction) of the mounting holes on the pipe parts through photographing by the visual system, and sends the deviation values to the servo control system; the servo system corrects the mounting position of the bushing based on the received deviation values, realizing the automatic centering of the bushing and the mounting hole, and ensuring the accurate installation of the bushing.

[0013] The present utility model has the following advantages:

[0014] 1. After placing the pipe fitting and the bushing on the fixture, first, two sets of visual systems on the left and right sides simultaneously take photos of the positions of the bushing mounting holes on the pipe fitting. The visual systems calculate the position deviations of the mounting holes in two directions (Y-direction and Z-direction) from the standard template; the deviation values are sent to the corresponding servo motion systems respectively; the servo motion systems in two directions (Y-direction and Z-direction) correct the positions of the bushing pressing according to the deviation values, ensuring the centering of the bushing and the mounting hole on the pipe fitting to accurately install the bushing.

[0015] 2. The correction of the mounting position of the bushing is carried out by the servo systems in two directions, with accurate positions. It is applicable to the installation of different products through program control, and the workload of hardware switching is extremely small, improving the equipment utilization rate.

[0016] 3. The two side visual systems simultaneously take photos and position the pipe fitting, reducing the installation man-hours. BRIEF DESCRIPTION OF THE DRAWINGS
