Description

Technical Field

[0001] This utility model relates to the technical field of pipe fitting inspection, specifically to a testing device for nickel-copper ultra-thick wall pipe fittings. Background Technology

[0002] The nickel-copper ultra-thickness pipe fitting testing equipment is a specialized device used for quality inspection of nickel-copper pipe fittings with wall thicknesses exceeding the conventional range. It is mainly used to detect internal defects, dimensional accuracy, and material properties of pipe fittings to ensure that they meet relevant standards and usage requirements.

[0003] A search revealed Chinese patent publication number CN222280308U, which discloses a vehicle pipe fitting testing device. This device aims to provide a testing method that facilitates obtaining the strength withstand capability at different locations, thereby improving accuracy. In this device, an inverted U-shaped frame is fixedly connected to the top of the testing platform. A pressure plate is mounted within the U-shaped frame via a telescopic adjustment mechanism for driving the pressure plate to move radially perpendicular to the pipe fitting under test, and a translation adjustment mechanism for driving the pressure plate to move axially along the pipe fitting under test. Inside the U-shaped frame, on both sides, are fixed T-plates and sliding T-plates. On the side closest to each of the fixed and sliding T-plates, there are bearing rings for clamping the pipe fitting under test. The sliding T-plate is mounted inside the U-shaped frame via a mounting mechanism located on the outside of the frame. This device, through the movement of the telescopic and translation adjustment mechanisms, can cause the pressure plate to press against the pipe fitting from different directions, performing strength testing. This facilitates obtaining data on the strength withstand capability at different locations, improving the accuracy of the testing.

[0004] However, when the testing equipment tests the pressure of pipe fittings, the operator needs to insert the pipe fitting into the bearing ring and hold the pipe fitting by hand until the bearing ring on the moving end is on the pipe fitting. After the test is completed, the operator needs to manually remove the pipe fitting before the next pipe fitting can be placed, which reduces the efficiency of the testing work. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a nickel-copper ultra-thick wall pipe testing device. This device solves the problem that when testing the pressure of pipe fittings, operators need to insert the pipe fitting into the bearing ring and hold it by hand until the bearing ring on the moving end is fitted onto the pipe fitting. After the test is completed, the pipe fitting needs to be manually removed before subsequent pipe fittings can be placed, thus reducing the efficiency of the testing work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nickel-copper ultra-thick wall pipe testing device, comprising a worktable, a linear motor and a push plate fixedly mounted on the worktable, a support frame fixedly mounted on the upper end of the worktable, a cylinder fixedly mounted on the upper end of the support frame, the output shaft of the cylinder extending through the interior of the support frame to the lower end of the support frame and fixedly connected to a pressure plate, an arc-shaped groove provided inside the top surface of the worktable, the arc-shaped groove being located directly below the pressure plate, a push plate slidably connected inside the arc-shaped groove, a moving plate fixedly connected to the moving end of the linear motor, the moving plate being L-shaped, and the lower end of the moving plate being fixedly connected to the upper end of the push plate.

[0007] Preferably, a U-shaped frame is fixedly installed on the left side wall of the workbench. A bidirectional screw is rotatably connected between the two side walls of the U-shaped frame. One end of the bidirectional screw extends through the interior of the U-shaped frame to the exterior of the U-shaped frame and is fixedly connected to a handwheel. An adjusting plate is symmetrically slidably connected inside the U-shaped frame. Rollers are rotatably connected at equal intervals inside the side wall of the adjusting plate. The adjusting plate is symmetrically threaded onto the rod wall of the bidirectional screw, thereby facilitating the clamping and limiting of the placed pipe fittings.

[0008] Preferably, a sliding rod is fixedly installed between the two end side walls inside the U-shaped frame, and the upper end of the adjusting plate is slidably sleeved on the rod wall of the sliding rod, thereby facilitating the limiting of the position of the adjusting plate.

[0009] Preferably, a pressure sensor is installed inside the pressure plate, and a display is fixedly installed on the side wall of the support frame. The display is connected to the pressure sensor via a connecting cable, thereby enabling the pressure detection and display of the pressure plate on the pipe fitting, which is convenient for staff to observe.

[0010] Preferably, the left end of the arc-shaped groove is open, the push plate is semi-circular, and the diameter of the arc-shaped groove is equal to the diameter of the push plate, thereby facilitating the removal of the pipe fitting.

[0011] This invention provides a testing device for nickel-copper ultra-thick wall pipe fittings. It has the following beneficial effects: This nickel-copper ultra-thick wall pipe testing equipment, when used, can conveniently move the placed pipe step by step through the cooperation between the set linear motor and the push plate, and can perform testing work on different positions. After the testing work is completed, it can be directly discharged through the arc groove, so that the linear motor can be reset, which is convenient for the placement of subsequent pipes. This nickel-copper ultra-thick wall pipe testing equipment, through the cooperation between the set adjustment plate and the rotating roller, can effectively compress the pipe during the pushing process, preventing the pipe from shifting or falling off.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0015] Please see Figure 1-3This utility model provides a testing device for nickel-copper ultra-thick wall pipe fittings, including a workbench 1, a linear motor 12 and a push plate 11 fixedly mounted on the workbench 1, a support frame 2 fixedly mounted on the upper end of the workbench 1, a cylinder 3 fixedly mounted on the upper end of the support frame 2, the output shaft of the cylinder 3 extending through the interior of the support frame 2 to the lower end of the support frame 2, and a pressure plate 5 fixedly connected thereto, an arc-shaped groove 10 provided inside the top surface of the workbench 1, the arc-shaped groove 10 being located directly below the pressure plate 5, the push plate 11 being slidably connected inside the arc-shaped groove 10, a moving plate 13 fixedly connected to the moving end of the linear motor 12, the moving plate 13 being L-shaped, the lower end of the moving plate 13 being fixedly connected to the upper end of the push plate 11, a pressure sensor being installed inside the pressure plate 5, and the side of the support frame 2... A display 4 is fixedly installed on the wall, and the display 4 is connected to the pressure sensor via a connecting cable. The left end of the arc groove 10 is open, and the push plate 11 is semi-circular. The diameter of the arc groove 10 is equal to the diameter of the push plate 11. When performing pressure testing on the pipe fitting, the linear motor 12 is used to move the push plate 11 to the right end of the arc groove 10. Then, the pipe fitting is placed inside the arc groove 10, and the linear motor 12 is used to move the pipe fitting to a new position. The cylinder 3 is opened, and the pressure plate 5 presses the pipe fitting. The pressure value is displayed on the display 4 by the pressure sensor inside the pressure plate 5. Then, the pressure plate 5 is moved upward, and the linear motor 12 pushes the pipe fitting again, so that the process can be carried out continuously, and the side wall of the pipe fitting can be completely tested. Example 2:

[0016] To facilitate the limiting of the pipe fitting, in this embodiment, as follows: Figure 1-3 As shown, a U-shaped frame 6 is fixedly installed on the left side wall of the workbench 1. A bidirectional screw 8 is rotatably connected between the two side walls of the U-shaped frame 6. One end of the bidirectional screw 8 extends through the interior of the U-shaped frame 6 to the exterior of the U-shaped frame 6 and is fixedly connected to a handwheel 9. An adjusting plate 15 is symmetrically slidably connected inside the U-shaped frame 6. Rollers 14 are rotatably connected at equal intervals inside the side wall of the adjusting plate 15. The adjusting plate 15 is symmetrically threaded onto the rod wall of the bidirectional screw 8. A sliding rod 7 is fixedly installed between the two side walls of the U-shaped frame 6. The upper ends of the adjusting plate 15 are slidably sleeved onto the rod wall of the sliding rod 7. The distance between the two adjusting plates 15 is adjusted according to the diameter of the pipe until the roller 14 is in contact with the side wall of the pipe and provides a certain supporting force to the side wall of the pipe, which can prevent the pipe from tilting due to its own weight when it moves.

[0017] It should be noted that, in this embodiment, as Figure 1-3As shown, when performing pressure testing on the pipe fitting, the linear motor 12 is first used to move the push plate 11 to the right end of the arc groove 10. Then, the pipe fitting is placed inside the arc groove 10, and the linear motor 12 is used to move the pipe fitting to a new position. The cylinder 3 is opened, and the pressure plate 5 presses the pipe fitting. The pressure value is displayed on the display 4 by the pressure sensor inside the pressure plate 5. Then, the pressure plate 5 is moved upward, and the linear motor 12 pushes the pipe fitting again, so that the process is continuous. This allows for complete testing of the side wall of the pipe fitting. The distance between the two adjusting plates 15 is adjusted according to the diameter of the pipe fitting until the rotating roller 14 is in contact with the side wall of the pipe fitting and provides a certain supporting force to the side wall of the pipe fitting. This prevents the pipe fitting from tilting due to its own weight when it moves to a new position.
