Abstract
Description
Technical Field
[0001] This utility model relates to the field of X-ray component testing technology, specifically a tooling for testing the performance of X-ray tube filaments. Background Technology
[0002] In an X-ray tube, the performance of the filament plays a crucial role. The quality of the X-ray tube filament directly affects the X-ray generation efficiency, imaging quality, and the lifespan of the X-ray tube assembly. Therefore, performance testing of some filaments is usually required before installation.
[0003] The current method of testing filament performance requires energizing or cyclically switching the filament on and off for a long time (e.g., energizing for 10 seconds and de-energizing for 5 seconds, and repeating this cycle) to observe whether the filament will break or degrade due to thermal expansion and contraction. However, this method must be tested in a protective gas environment to avoid oxidation. If tested in an open environment, the filament will burn out, thus failing to reflect the true lifespan of the filament. Utility Model Content

[0025] like Figure 1-6 As shown, this utility model provides a tooling for testing the performance of an X-ray tube filament 13, including a test control box 1 for testing the filament 13, a vacuum pump 11 electrically connected to the test control box 1, a clamp 12 for clamping the filament 13, a support platform 2, a test bracket 3, and a sealing cover 4.
[0026] In this embodiment, the clamp 12 is made of conductive material, and the clamp 12 includes a first clamp 121 for clamping one end of the filament 13 and a second clamp 122 for clamping the other end of the filament 13.
[0027] The top surface of the support platform 2 has a first through hole 22.
[0028] The bottom end of the test bracket 3 is located above the first through hole 22 of the support platform 2. The test bracket 3 includes a test base 35 located above the first through hole 22 and a first test rod 31 and a second test rod 32 arranged vertically on the test base 35.
[0029] In this embodiment, the first clamp 121 is mounted on the first test rod 31 via a first extension 311, and the second clamp 122 is mounted on the second test rod 32 via a second extension 321. The first test rod 31 contains a first conductor 33 electrically connected to the test control box 1, and the second test rod 32 contains a second conductor 34 electrically connected to the test control box 1. The first conductor 33 is electrically connected to the first clamp 121, and the second conductor 34 is electrically connected to the second clamp 122. It should be understood that one end of the first extension 311 is fixedly mounted on the first test rod 31, while the other end of the first extension 311 is fixedly connected to the first clamp 121. Similarly, one end of the second extension 321 is fixedly mounted on the second test rod 32, while the other end of the second extension 321 is fixedly connected to the second clamp 122.
[0030] In other words, one end of the filament 13 is clamped in the first clamp 121, and the other end of the filament 13 is clamped in the second clamp 122. The first conductor 33 in the first test rod 31 is electrically connected to the first clamp 121, and the second conductor 34 in the second test rod 32 is electrically connected to the second clamp 122. Therefore, the test control box 1, the first conductor 33, the first clamp 121, the filament 13, the second clamp 122, and the second conductor 34 form a conductive circuit, and the filament 13 can be tested through the test control box 1.
[0031] Preferably, the first test rod 31 and the second test rod 32 are symmetrically arranged, and the first extension 311 and the second extension 321 are symmetrically arranged.
[0032] It should be understood that the first clamp 121 and the second clamp 122 correspond to each other, and there are multiple pairs of clamps, while the first extension 311 and the second extension 321 correspond to each other, that is, multiple pairs of first extensions 311 and second extensions 321 are arranged on the first test rod 31 and the second test rod 32.
[0033] The sealing cover 4 is used to install on the first through hole 22 to seal and cover the test bracket 3. It should be understood that by isolating and sealing the test bracket 3 from the outside world through the sealing cover 4, the filament 13 can have a testing environment that is not affected by the outside world, thus making it easier to conduct tests.
[0034] In this embodiment, the vacuum pump 11 is located below the support platform 2. The inlet of the vacuum pump 11 is connected to the first through hole 22 through the pipe 111, so as to evacuate the sealing cover 4 by means of the vacuum pump 11. It should be understood that after the sealing cover 4 seals the test bracket 3, the vacuum pump 11 can be started to evacuate the inside of the sealing cover 4, so that the inside of the sealing cover 4 is in a sealed vacuum environment. When the filament 13 is energized for testing, it can effectively reflect the true situation of the filament life.
[0035] It should be understood that the first conductor 33 and the second conductor 34 in this embodiment can be conductive wires, which pass through the tube 111 (the conductive wire and the tube 111 are sealed together) and the first through hole 22 and are disposed on the first test rod 31 and the second test rod 32.
[0036] Furthermore, the top surface of the support platform 2 is provided with a receiving groove 21, and the first through hole 22 is provided in the bottom wall of the receiving groove 21, wherein the sealing cover 4 is provided in the receiving groove 21.
[0037] Preferably, the bottom outer wall of the sealing cover 4 is set in the receiving groove 21 by a threaded connection. That is, the bottom outer wall of the sealing cover 4 is provided with external threads, and the side wall of the receiving groove 21 is provided with internal threads. It should be understood that after the filament 13 is tested, the sealing cover 4 can be rotated out of the receiving groove 21, making the installation and removal of the sealing cover 4 more convenient.
[0038] Specifically, the receiving groove 21 is circular in shape, and the outer wall of the sealing cover 4 is circular in shape, wherein the outer diameter of the sealing cover 4 is equal to the aperture of the receiving groove 21.
[0039] In this embodiment, the test chassis 35 is positioned above the first through hole 22 of the receiving groove 21 via multiple support rods 36. The test chassis 35 is circular, with its outer diameter smaller than the inner diameter of the sealing cover 4. It should be understood that the test chassis 35 will not obstruct the first through hole 22 (e.g., Figure 4 (As shown).
[0040] Furthermore, both the first conductor 33 and the second conductor 34 are elongated strips, with the first conductor 33 arranged along the length of the first test rod 31 and the second conductor 34 arranged along the length of the second test rod 32. It should be understood that the first conductor 33 can be disposed inside or on the outer wall of the first test rod 31, and the second conductor 34 can be disposed inside or on the outer wall of the second test rod 32.
[0041] Preferably, the first extension 311 and the second extension 321 are made of insulating material. The first extension 311 has a third conductor inside for electrically connecting the first clamp 121 and the first conductor 33, and the second extension 321 has a fourth conductor inside for electrically connecting the second clamp 122 and the second conductor 34. It should be understood that when the filament 13 is tested, the test control box 1, the first conductor 33, the third conductor, the first clamp 121, the filament 13, the second clamp 122, the fourth conductor, and the second conductor 34 can form a conductive circuit, thereby enabling the filament 13 to be tested normally.
[0042] In this embodiment, the sealing cover 4 is made of a transparent material. It should be understood that during the testing of the filament 13, the real-time status of the filament 13 can be observed directly through the transparent sealing cover 4, allowing for faster feedback.
[0043] It is worth noting that the test control box 1, vacuum pump 11, first conductor 33, second conductor 34, third conductor and fourth conductor in this utility model can all be implemented using products in the prior art, and their principles and structures will not be described in detail here.
