Description

Technical Field

[0001] This invention relates to the technical field of circular tube inspection, specifically to a one-time inspection device for multi-hole circular tubes. Background Technology

[0002] The single-use testing equipment for porous circular tubes is a specialized device designed for inspecting the porous structures of circular tubes. This equipment is commonly used in medical, industrial, and scientific research fields to ensure that the porous structure inside the tube meets specific design requirements and quality standards. It can complete a comprehensive inspection of the porous structure in a short time, improving work efficiency. Employing high-precision measurement technology, it ensures the reliability of the test results. Applicable to porous structure inspection in various fields, it has broad application prospects. The emergence of this equipment has greatly improved the efficiency and accuracy of porous structure inspection, providing strong support for research and production in related fields.

[0003] Common single-use testing equipment for multi-hole round tubes can only test round tubes of specific sizes and cannot adapt to round tubes of different lengths and widths. This greatly reduces the equipment's versatility and flexibility, resulting in low equipment utilization and increased equipment investment costs for enterprises. In addition, it requires manual handling of the round tubes to be placed into the indexing plate for testing, which has certain adverse effects on the user experience. Therefore, we propose a single-use testing equipment for multi-hole round tubes. Summary of the Invention

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this invention provides a one-time multi-hole inspection device for round tubes. It boasts advantages such as improved versatility and adaptability. A driving cylinder on the inner wall of the protective frame drives a lifting piston rod, which in turn moves the adjusting control frame up and down. This adapts to round tubes of varying lengths and widths, increasing the device's applicability. Simultaneously, it allows for quick and accurate insertion of the round tube into the inner side of the indexing plate for inspection. A guide connecting rod moves within the through-guide hole, enhancing guiding stability. A buffer spring between the adjusting control frame and the protective frame provides enhanced cushioning. A movable adjusting block is fitted onto the outer wall of the threaded adjusting rod through a through-threaded hole, and a guide block is fitted onto the outer wall of the guide stabilizing rod through a guide through-hole, further enhancing guiding stability. A control motor on the inner side of the control port drives the threaded adjusting rod to rotate within the adjusting groove, allowing the movable adjusting block to move within the threaded adjusting rod. The guide block moves on the outer wall of the guide stabilizer rod, which simultaneously drives the clamping connecting frame and the support frame to be aligned at the front end of the adjustment control frame. The support frame at the lower end of the clamping connecting frame provides support and stability. When the clamping connecting frame moves in opposite directions, the clamping semicircular frame connected to the connecting frame will also move in opposite directions to clamp and position the round tube to be tested. The inner anti-slip rubber pad on the inner wall of the clamping semicircular frame can enhance friction, making the clamping more secure and providing a certain degree of protection. It can adapt to round tubes of different widths, increasing the applicability of the equipment, strengthening the stability of the round tube during the testing process, avoiding testing errors caused by hand shaking or positional deviation, thereby improving the accuracy and reliability of the testing. At the same time, it can prevent the round tube from accidentally slipping or moving during the testing process, reducing potential risks to operators and equipment, improving the safety of the testing process, and effectively solving the problems in the background technology.

The design of the limit plate 12 can prevent the adjustment control frame 10 from excessive lifting and lowering, playing a limit protection role and avoiding damage or safety accidents caused by excessive adjustment.

[0029] Furthermore, a control port 13 is provided in the middle of the front end of the adjustment control frame 10. A control motor 14 is fixedly connected to the inner wall of the control port 13. Adjustment slots 15 and guide slots 17 are provided on both sides of the front end of the adjustment control frame 10. The guide slot 17 is located at the lower end of the adjustment slot 15.

The inner anti-slip rubber pad 27 can increase friction, prevent the workpiece from sliding during clamping, and improve the reliability of clamping.

[0031] Furthermore, the outer wall of the drive cylinder 8 is fixedly connected to the inner wall of the protective frame 4. The drive cylinder 8 drives the lifting piston rod 9 to pass through the inner wall of the upper end of the protective frame 4 and move. The upper end of the lifting piston rod 9 is fixedly connected to the lower end of the adjustment control frame 10. The upper ends of the buffer spring member 6 and the guide connecting rod 11 are fixedly connected to the four corners of the lower end of the adjustment control frame 10.

[0032] Furthermore, the outer wall of the control motor 14 is fixedly connected to the inner wall of the control port 13. One end of the threaded adjusting rod 16 passes through the inner wall of the adjusting movable groove 15 and is movably connected to both ends of the control motor 14. Both ends of the guide stabilizing rod 18 are fixedly connected to the inner wall of the guide groove 17. Through the cooperation of the threaded adjusting rod 16 and the movable adjusting block 20, the position of the clamping semicircular frame 26 can be precisely adjusted. The threaded transmission has self-locking properties, which can ensure that the adjusted position is stable and not easy to loosen. The control motor 14 can control the moving distance of the movable adjusting block 20 by adjusting the rotation angle of the threaded adjusting rod 16, thereby controlling the clamping force of the clamping semicircular frame 26 on the object. This design allows the clamping force to be precisely controlled according to actual needs and is suitable for objects of different sizes and shapes.

[0033] Furthermore, one side of the movable adjustment block 20 is fixedly connected to the rear end of the clamping connecting frame 19.

One side of the guide block 23 is fixedly connected to the rear end of the support frame 22. The guide block 23 is sleeved on the outer wall of the guide stabilizing rod 18 through the guide through hole 24. The cooperation between the guide stabilizing rod 18 and the guide block 23 ensures the stability of the movable adjustment block 20 during movement and prevents it from shifting or shaking during adjustment, thereby ensuring the accuracy and reliability of clamping.

[0034] Furthermore, one end of the connecting frame 25 is fixedly connected to one side of the clamping connecting frame 19, and the other end of the connecting frame 25 is fixedly connected to the outer wall of the clamping semicircular frame 26. One side of the inner anti-slip rubber pad 27 is attached to the inner wall of the clamping semicircular frame 26 with strong adhesive for positioning. The attachment of the inner anti-slip rubber pad 27 to the inner wall of the clamping semicircular frame 26 with strong adhesive can increase the friction during clamping, prevent the clamped object from sliding or falling off, and improve the firmness and safety of clamping.

[0035] Working Principle: A disposable multi-hole testing device for round tubes includes a testing worktable 1, an indexing plate 2, pin needles 3, a protective frame 4, a positioning frame 5, a buffer spring 6, a through guide hole 7, a drive cylinder 8, a lifting piston rod 9, an adjustment control frame 10, a guide connecting rod 11, a limit plate 12, a control port 13, a control motor 14, an adjustment groove 15, a threaded adjustment rod 16, a guide groove 17, a guide stabilizing rod 18, a clamping connecting frame 19, a movable adjustment block 20, a through threaded hole 21, a support frame 22, a guide block 23, a guide through hole 24, a connecting frame 25, a clamping semi-circular frame 26, and an inner anti-slip rubber pad 27. In use, the drive cylinder 8 drives the lifting piston rod 9 on the inner wall of the protective frame 4, which in turn drives the adjustment control frame 10 to move up and down. The guide connecting rod 11 moves inside the through guide hole 7, which can enhance the guiding stability. The buffer spring 6 between the adjustment control frame 10 and the protective frame 4 can play a role in enhancing the buffer. The moving adjustment block 20 is sleeved on the outer wall of the threaded adjustment rod 16 through the through threaded hole 21. The guide block 23 is sleeved on the outer wall of the guide stabilizing rod 18 through the guide through hole 24, which can enhance the guiding stability. The control motor 14 inside the control port 13 can drive the threaded adjustment rod 16 to rotate inside the adjusting movable groove 15, so that the moving adjustment block 10 moves up and down. The movable adjusting block 20 moves on the outer wall of the threaded adjusting rod 16, and the guide block 23 moves on the outer wall of the guide stabilizing rod 18. Simultaneously, it can drive the clamping connecting frame 19 and the support frame 22 to be aligned at the front end of the adjusting control frame 10. The support frame 22 at the lower end of the clamping connecting frame 19 provides support and stability. When the clamping connecting frame 19 moves in opposite directions, the clamping semi-circular frame 26 connected through the connecting frame 25 will also move in opposite directions to clamp and position the round tube to be tested. The round tube can be quickly and accurately inserted into the inner side of the indexing plate 2 for testing via the PIN needle 3. The inner anti-slip rubber pad 27 on the inner wall of the clamping semi-circular frame 26 enhances friction, making... The clamping mechanism is more secure and provides a certain degree of protection. It can accommodate round tubes of different lengths and widths, increasing the applicability of the equipment. It enhances the stability of the round tube during the inspection process, avoiding inspection errors caused by hand shaking or positional shifts, thereby improving the accuracy and reliability of the inspection. At the same time, it can prevent the round tube from accidentally slipping or moving during the inspection process, reducing potential risks to operators and equipment, and improving the safety of the inspection process. During inspection, the round tube is inserted longitudinally into the indexing plate 2. The indexing plate 2 is equipped with a PIN pin pushing device in the circumferential direction, which pushes the PIN pin 3 into the circumferential hole of the round tube. If it is not inserted, the round tube is unqualified.
