Description

Technical Field

[0001] The utility model relates to the technical field of semi - automatic coaxial adjustment detection, in particular to a device capable of automatically identifying the diameter of irregular circular tubes and adjusting the coaxiality. Background Technique

[0002] The device for automatically identifying the diameter of irregular circular tubes and adjusting the coaxiality is based on image processing and computer vision technology. It mainly uses image processing libraries such as OpenCV to realize the identification and diameter measurement of circular tubes. The coaxiality adjustment device first places the first circular tube on the Y - shaped table, establishes a virtual circle through the system, the laser displacement sensor detects the distance, calculates the actual center position of the circular tube, and the adjusting wheel adjusts the opening according to the data of the laser displacement sensor, thereby adjusting the center height of the second circular tube, so as to ensure the coaxiality of adjacent products.

[0003] For the existing circular tube coaxiality adjustment device, when the circular tube is placed on the Y - shaped table, it cannot be kept stable at the back, and the placement is unstable. The circular tube may displace or shake during the processing. The unstable placement will lead to measurement errors and requires frequent adjustment and re - setting, which will occupy a large amount of production time and reduce the overall efficiency. Therefore, a coaxiality adjustment device that can always maintain the stability of the circular tube is needed. Summary of the Utility Model

For the existing circular tube coaxiality adjustment device, when the circular tube is placed on the Y - shaped table, it cannot be kept stable at the back, and the placement is unstable. The circular tube may displace or shake during the processing. The unstable placement will lead to measurement errors and requires frequent adjustment and re - setting, which will occupy a large amount of production time and reduce the overall efficiency.

[0005] To solve the above - mentioned technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a device capable of automatically identifying the diameter of irregular circular tubes and adjusting the coaxiality, including:

[0007] A coaxial adjustment component, the coaxial adjustment component includes a circular tube body;

[0008] A support component, the support component includes an electric push rod, a support plate, a connecting rod, a baffle and a spring;

[0009] The electric push rod is installed below the middle of the outer surface of the circular tube body, the support plate is fixedly connected to the output end of the electric push rod, the connecting rod is fixed on the upper surface of the support plate, the baffle is fixed on the upper surface of the connecting rod, and the spring penetrates through the lower end of the outer surface of the connecting rod.

[0010] Furthermore, a Y-shaped platform is connected to the lower surface of the circular tube body. A laser displacement sensor is installed inside the Y-shaped platform. An electric cylinder is fixed to the lower surface of the Y-shaped platform. A movable plate is slidably installed on one side of the upper surface of the electric cylinder, and an adjusting wheel is installed above the movable plate.

[0011] Furthermore, a support platform is arranged above the support plate. A support groove is formed on the upper surface of the support platform. A movable hole is formed on one side of the upper surface of the support platform. A connecting shaft is connected to one side of the outer surface of the support platform, and a support wheel is rotatably penetrated through the outer surface of the connecting shaft.

[0012] Furthermore, the circular tube body is located in the support groove, and the outer surface of the circular tube body is in contact with the support wheel. Four support wheels are provided and are respectively installed on the outer surface of the support platform.

[0013] Furthermore, it further includes a connecting component;

[0014] The connecting component includes a connecting plate, a circular hole, a rotating shaft and an inclined groove;

[0015] The connecting plate is fixedly connected to the upper surface of the movable plate. The circular hole is formed in the upper end of the outer surface of the connecting plate.

[0017] Compared with the prior art, the advantages of the present utility model are as follows:

[0018] First, in the present utility model, through the coaxial adjustment component and the support component provided, when adjusting and detecting the coaxiality, the staff first places the first circular tube body on the upper surfaces of the Y-shaped platform and the support platform, measures through the laser displacement sensor, and calculates the position of the center of the circle through system simulation. Then, the first circular tube body is removed, and the second circular tube body is placed on the Y-shaped platform. Again, it is measured through the laser displacement sensor. To ensure that the centers of the two circles are in the same position, the controller controls the electric cylinder. The electric cylinder drives the two movable plates to move towards each other. The two movable plates drive the two adjusting wheels to move relatively, pushing the second circular tube body upward so that the center of the second circular tube body coincides with the center of the first circular tube body.

When the rotating shaft adjusts the height of the circular tube body, it rotates within the circular hole. At the same time, inclined slots are opened on both sides of the outer surface of the adjusting wheel, reducing the contact area with the circular tube body. The movement of the two adjusting wheels can adapt to circular tube bodies of different diameters, enhancing the versatility and adaptability of the device. Reducing the contact area can reduce the friction between the adjusting wheel and the circular tube body, thereby reducing wear and extending the service life of the device, and protecting the aesthetic appearance of the product.

[0032] In order to make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0033] Please refer to Figures 1 - 4 As shown, this embodiment is a device that can automatically identify the diameter of irregular circular tubes and adjust the coaxiality, including:

[0034] A coaxial adjustment component, which includes a circular tube body 11;

[0035] The lower surface of the circular tube body 11 is connected to a Y-shaped platform 14. A laser displacement sensor 15 is installed inside the Y-shaped platform 14. An electric cylinder 12 is fixed on the lower surface of the Y-shaped platform 14. A movable plate 13 is slidably installed on one side of the upper surface of the electric cylinder 12, and an adjusting wheel 131 is installed above the movable plate 13;

[0036] The laser displacement sensor 15 feeds back the measurement data to the control system, and the control system makes precise adjustments according to the deviation. The electric cylinder 12 serves as the power source of the entire adjustment device and adjusts the relative movement of the two movable plates 13 according to the instructions of the control system;

[0037] A support component, which includes an electric push rod 21, a support plate 22, a connecting rod 23, a baffle 231, and a spring 24;

[0038] The electric push rod 21 is installed below the middle of the outer surface of the circular tube body 11. The support plate 22 is fixedly connected to the output end of the electric push rod 21. The connecting rod 23 is fixed on the upper surface of the support plate 22. A baffle 231 is fixed on the upper surface of the connecting rod 23. The spring 24 passes through the lower end of the outer surface of the connecting rod 23;

[0039] The electric push rod 21 serves as the power source of the entire support component. Through the telescopic movement of the electric push rod 21, the support plate 22 can be driven to move up and down, so that the entire support component can detect and adjust the height as needed;

[0040] Above the support plate 22, there is a support platform 25. The upper surface of the support platform 25 is provided with a support groove 251. One side of the upper surface of the support platform 25 is provided with a movable hole 26. One side of the outer surface of the support platform 25 is connected with a connecting shaft 27. The outer surface of the connecting shaft 27 is rotatably penetrated by a support wheel 28;

[0041] After the electric cylinder 12 adjusts the position of the second circular tube body 11, the spring 24 synchronously pushes the support platform 25 upward, so that the support groove 251 contacts the circular tube body 11 to provide stable support. Regardless of the diameter of the second circular tube body 11, the support platform 25 can always contact the outer surface of the circular tube through the support wheel 28 to achieve effective support;

[0042] Working principle:

[0043] When adjusting and detecting the coaxiality;

[0044] First, the staff first places the first circular tube body 11 on the upper surfaces of the Y-shaped platform 14 and the support platform 25, measures it through the laser displacement sensor 15, and calculates the position of the center of the circle through system simulation;

[0045] Next, remove the first circular tube body 11, then place the second circular tube body 11 on the Y-shaped platform 14, and measure it again through the laser displacement sensor 15. To ensure that the centers of the two circles are in the same position, the controller controls the electric cylinder 12. The electric cylinder 12 drives the two movable plates 13 to move towards each other. The two movable plates 13 drive the two adjusting wheels 131 to move relatively, pushing the second circular tube body 11 upward so that the center of the second circular tube body 11 coincides with the center of the first circular tube body 11;

[0046] At this time, under the elastic force of the spring 24, the spring 24 pushes the support platform 25 upward, so that the support groove 251 contacts the second circular tube body 11, and adjusts the support wheel 28 to contact the outer surface of the second circular tube body 11. Regardless of the diameter of the second circular tube body 11, the support platform 25 always supports the circular tube body 11;

[0047] In this step, regardless of the diameter of the circular tube body 11, the support platform 25 and the support wheel 28 can adapt, enhancing the versatility, adaptability and stability of the equipment.

[0048] Please refer to Figure 4 As shown, on the basis of the above-mentioned Embodiment 1, this embodiment further includes:

[0049] Connection component;

[0050] The connection component includes a connection plate 31, a circular hole 32, a rotating shaft 33 and an inclined groove 34;

[0051] The connecting plate 31 is fixedly connected to the upper surface of the movable plate 13. A circular hole 32 is opened at the upper end of the outer surface of the connecting plate 31. The rotating shaft 33 penetrates through the inside of the circular hole 32. Oblique grooves 34 are opened on both sides of the outer surface of the adjusting wheel 131;

[0052] The connecting plate 31 bears the rotating shaft 33 and the adjusting wheel 131, ensuring the stability of these components during operation;

[0053] The oblique grooves 34 are opened on both sides of the outer surface of the adjusting wheel 131, reducing the contact area and friction with the main body of the circular tube 11. This can not only reduce wear but also lower the noise generated during operation, improving the working environment;

[0054] Working principle:

[0055] During the relative movement of the two movable plates 13;

[0056] First of all, the outer surfaces of the two adjusting wheels 131 are in contact with the main body of the circular tube 11. When the rotating shaft 33 adjusts the height of the main body of the circular tube 11, it will rotate within the circular hole 32. At the same time, the oblique grooves 34 are opened on both sides of the outer surface of the adjusting wheel 131, reducing the contact area with the main body of the circular tube 11;

[0057] The movement of the two adjusting wheels 131 can adapt to circular tube bodies 11 of different diameters, enhancing the versatility and adaptability of the equipment;

[0058] This step can reduce the friction between the adjusting wheel 131 and the main body of the circular tube 11, thereby reducing wear, extending the service life of the equipment, and protecting the aesthetic appearance of the product.
