DETAILED DESCRIPTION

[0022] The following is a further description of a specific implementation of an X-ray tube primary light testing device of the present invention in conjunction with the accompanying drawings.

[0023] The present embodiment aims to provide an X-ray tube primary light testing device, which is mainly used to test and evaluate the performance and quality of the X-ray tube. By testing the parameters such as the intensity and energy distribution of the primary light generated by the X-ray tube, the stability, life, efficiency and other performance indicators of the X-ray tube can be evaluated. The current X-ray tube primary light testing device can only adjust the distance between the ray source 2, the detector 3 and the test product 4, but cannot be adjusted at multiple angles and multiple positions, resulting in that the test product 4 can only be adjusted frequently during the test, resulting in cumbersome operation and reduced test efficiency.

[0024] like Figure 1-10 The X-ray tube primary light testing device shown includes a protective shell 1 for testing a test object 4, a ray source 2 and a detector 3 which are arranged in the protective shell 1 and have adjustable positions. The positions of the ray source 2 and the detector 3 are adjusted so that different detection requirements can be met. The detector 3 is used to receive the signal emitted by the ray source 2.

[0025] like Figure 1 As shown, the test product 4 is placed in the protective housing 1, which can effectively protect the test product 4 from the influence of the external environment.

[0026] like Figure 2-9As shown, the protective shell 1 is provided with two sets of adjustment mechanisms which are arranged opposite to each other and are distributed on the left and right sides of the test product 4. The adjustment mechanisms are used to adjust the positions and angles of the radiation source 2 and the detector 3 in the protective shell 1. Each adjustment mechanism includes a position adjustment component, a movable plate 5 which is transmission-connected to the position adjustment component, an angle adjustment component arranged on the movable plate 5 and a mounting plate 6 which is transmission-connected to the angle adjustment component, so as to adjust the position of the movable plate 5 in the protective shell 1 through the position adjustment component. Since the radiation source 2 and the detector 3 are assembled on the movable plate 5 through the mounting plate 6 and the angle adjustment component, when the movable plate 5 moves under the action of the position adjustment component, it can drive the radiation source 2 and the detector 3 to move together. The radiation source 2 and the detector 3 are respectively mounted on the mounting plate 6, so that the angle of the radiation source 2 or the detector 3 can be adjusted. When the angle adjustment component is adjusted, it can drive the mounting plate 6 to swing, so as to realize the adjustment of the angles of the radiation source 2 and the detector 3, which can reduce unnecessary detection time and improve detection efficiency.

[0027] like Figure 2-4 As shown, the position adjustment assembly can drive the moving plate 5 to move.

[0028] Specifically, the position adjustment assembly includes three groups of guide assemblies 7 extending in the left-right direction and arranged in a circular array at intervals, sliders 8 adapted to the guide assemblies 7, and connecting rods 9 hingedly connected to the sliders 8; the connecting rods 9 are hingedly connected to the movable plate 5 so that the movable plate 5 can be moved in position through the different positions of the three sliders 8 on the guide assembly 7.

[0029] The guide assembly 7 includes a main limit rod 701 extending along the left and right directions and threaded rods 702 distributed on both sides of the main limit rod 701; the slider 8 is threadedly mounted on the threaded rod 702; each guide assembly 7 is provided with a first driving source 10 on the side away from the test product 4, and the first driving source 10 is driven to start, so that the output shaft of the first driving source 10 drives the threaded rod 702 to rotate, so that the slider 8 moves left and right along the main limit rod 701, and the first driving source 10 is connected to the threaded rod 702 to rotate the threaded rod 702. Each threaded rod 702 is driven by a first driving source 10, and the three groups of guide assemblies 7 move in coordination, so that the movable plate 5 can be accurately moved to any position.

[0030] In other embodiments, each guide assembly 7 includes a main limit rod 701 and an electric telescopic rod, and the electric telescopic rod is used to drive the slider 8 to move along the main limit rod 701, so that the three sliders 8 can move in coordination, thereby driving the movable plate 5 to move.

[0031] like Figure 6-9 As shown, under the action of the angle adjustment component, the mounting plate 6 can be driven to adjust the angle to improve the imaging quality.

[0032] Specifically, each angle adjustment component includes a left-right swing component 11 and an up-down swing component 12; a second driving source 13 and a third driving source 14 are fixedly provided on the movable plate 5, and by driving the second driving source 13 and the third driving source 14 to start, the second driving source 13 and the third driving source 14 can respectively drive the left-right swing component 11 and the up-down swing component 12 to move, so that the mounting plate 6 swings in the up-down, left-right and right-side directions to adjust the optimal irradiation angle of the radiation source 2 and the detector 3.

[0033] The second driving source 13 is connected to the left and right swinging assembly 11, the third driving source 14 is connected to the up and down swinging assembly 12, and a connecting seat 19 is fixedly provided on the mounting plate 6, and the connecting seat 19 is connected to the left and right swinging assembly 11 and the up and down swinging assembly 12, so that the mounting plate 6 can swing up and down and left and right. Through the setting of the connecting seat 19, the mounting plate 6 can be better connected with the left and right swinging assembly 11 and the up and down swinging assembly 12, thereby improving the stability of the mounting plate 6.

[0034] The left and right swinging assembly 11 includes a worm 1101 which is transmission-connected to the second driving source 13 and a worm wheel 1102 which meshes with the worm 1101. The second driving source 13 is driven to start so that the output shaft of the second driving source 13 can drive the worm 1101 to rotate. Since the worm 1101 and the worm wheel 1102 mesh with each other, the worm wheel 1102 can be driven to rotate. A rotating shaft 15 which is vertically arranged with the worm 1101 is fixedly provided on the worm wheel 1102. The rotating shaft 15 is fixedly connected to the connecting seat 19. When the worm wheel 1102 rotates, the connecting seat 19 can be driven to swing through the rotating shaft 15, thereby driving the mounting plate 6 to swing.

[0035] The up and down swinging assembly 12 includes a sleeve 1201 which is transmission-mounted on the output shaft of the third driving source 14 and a U-shaped frame 1202 which is fixed on the sleeve 1201. The third driving source 14 is driven to start, so that the output shaft of the third driving source 14 drives the sleeve 1201 to rotate. When the sleeve 1201 rotates, it can drive the U-shaped frame 1202 to rotate, and then drive the movable plate 5 to rotate through the connecting seat 19.

[0036] In this embodiment, the end of the worm 1101 away from the second driving source 13 is rotatably inserted into the sleeve 1201; the side of the U-shaped frame 1202 away from the third driving source 14 is rotatably sleeved on the worm 1101, and the rotating shaft 15 is rotated on the U-shaped frame 1202.

[0037] The U-shaped frame 1202 is provided with a through hole 16 for the worm wheel 1102 to rotate. With the through hole 16 , the worm wheel 1102 will not be affected by the U-shaped frame 1202 when rotating.

[0038] like Figure 4As shown, the output end of the first driving source 10 is transmission-connected with one of the threaded rods 702; gears 17 are fixed on the two threaded rods 702, respectively, and the two gears 17 are meshed with each other, so that the two threaded rods 702 rotate, and the first driving source 10 drives one of the threaded rods 702 and the gear 17 to rotate. Since the two gears 17 are meshed with each other, the other threaded rod 702 can be driven to rotate, and the two threaded rods 702 work at the same time to share the load, thereby improving the transmission efficiency of the entire system.

[0039] like Figure 1 and Fig.10 As shown, the test product 4 is placed on the placement platform 1803 to facilitate better testing.

[0040] Specifically, a support assembly 18 is provided in the protective shell 1 . The support assembly 18 is located between the radiation source 2 and the detector 3 and below the test object 4 to support the test object 4 .

[0041] The support assembly 18 includes a fixed block 1801 fixed on the inner wall of the protective shell 1, a telescopic device 1802 fixedly connected to the fixed block 1801, and a placement platform 1803 fixedly connected to the end of the movable rod of the telescopic device 1802; the telescopic device 1802 is vertically arranged in the fixed block 1801. Through the setting of the telescopic device 1802, the height of the placement platform 1803 can be adjusted to place test products 4 of different heights, thereby improving the test effect.

[0042] In this embodiment, the protective housing 1 is provided with a flip door, which can be used to place the test product 4 and close it. Working principle: Place the test product 4 on the placement platform 1803, and then adjust the height of the placement platform 1803 through the telescopic device 1802 to ensure that the test product 4 is penetrated at the best angle. After the test product 4 is placed, the first driving source 10 can be driven to start, so that the output shaft of the first driving source 10 drives the threaded rod 702 to rotate, so that the three groups of sliders 8 move in coordination along the main limit rod 701. Under the action of the connecting rod 9, the movable plate 5 can be driven to move to adjust the position of the movable plate 5 in the protective shell 1.

[0043] Then, the second driving source 13 is driven to start, so that the output shaft of the second driving source 13 can drive the worm 1101 to rotate. Since the worm 1101 and the worm wheel 1102 are meshed with each other, the worm wheel 1102 can be driven to rotate. When the worm wheel 1102 rotates, the connecting seat 19 can be driven to swing through the rotating shaft 15, and then the mounting plate 6 can be driven to swing; the third driving source 14 is driven to start, so that the output shaft of the third driving source 14 drives the sleeve 1201 to rotate. When the sleeve 1201 rotates, it can drive the U-shaped frame 1202 to rotate, and then drive the movable plate 5 to rotate through the connecting seat 19, so as to adjust the position of the movable plate 5 and adjust the optimal irradiation angle of the radiation source 2.

[0044] Similar to the above operation, another adjustment mechanism is adjusted to adjust the position and angle of the detector 3 and match it with the radiation source 2. Then, the radiation source 2 is started, and the radiation source 2 penetrates the test object 4 and is collected by the detector 3. After the test of one test point is completed, the position and angle of the radiation source 2 and the detector 3 are adjusted to perform tests at different positions and angles. The test results at different positions and angles are compared to make the test results more accurate.

[0045] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to improve the accuracy and clarity of imaging by adjusting the position and angle of the ray source 2 and the detector 3, and to reduce unnecessary detection time and improve detection efficiency. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
