[0046] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] This preferred embodiment provides a cone beam CT detection loading tool, comprising a mounting base plate 1, an auxiliary support plate 2 and a clamping assembly 3, wherein:

[0048] A guide assembly 4 is provided on the mounting base plate 1;

[0049] The auxiliary support plate 2 can reciprocate on the mounting base plate 1 along the guide assembly 4, and the auxiliary support plate 2 and the mounting base plate 1 are locked by the locking member 5;

[0050] The clamping assembly 3 includes a first clamping member 31 disposed on the mounting base plate 1 and a second clamping member 32 disposed on the auxiliary support plate 2. The first clamping member 31 and the second clamping member 32 cooperate to clamp both ends of the product 400 under test and drive the product 400 under test to rotate.

[0051] In this embodiment, the product 400 to be tested is in the shape of a rod. The clamping assembly 3 can be replaced according to the shape and size of the product, and can be adapted to the detection of cylindrical objects within 120 mm and flat objects within 200 mm.

[0052] Therefore, the cone-beam CT detection carrier tooling 100 is designed as a modular structure, and the product to be tested 400 is reliably clamped through the clamping assembly 3. Since the auxiliary support plate 2 is movable, it can meet the detection requirements of objects of multiple sizes, has strong versatility, simple clamping operation, and improved detection efficiency.

[0053] Specifically, the guide assembly 4 includes two parallel guide rails 41, and the two guide rails 41 are distributed on both sides of the clamping assembly 3. A slider 42 is provided on each guide rail 41, and the two ends of the auxiliary support plate 2 are respectively fixedly connected to the sliders 42 on both sides, so that the auxiliary support plate 2 is mounted on the two guide rails 41 and the auxiliary support plate 2 is ensured to move accurately.

[0054] In particular, the locking member 5 includes a knob screw 51, and a plurality of locking holes 11 are provided on the mounting base plate 1 and on one side of the guide rail 41. The locking holes 11 are arranged at intervals along the length direction of the guide rail 41. A mounting groove 21 is provided on the auxiliary support plate 2. The knob screw 51 passes through the mounting groove 21 and is threadedly connected to any locking hole 11, so that the position of the auxiliary support plate 2 is locked.

[0055] Therefore, the auxiliary support plate 2 is fixed in the corresponding position by manually tightening the knob screw 51 with any locking hole 11, and because the mounting groove 21 is long and strip-shaped, the knob screw 51 can be moved and can always be connected with a locking hole 11, thereby simply realizing the locking function.

[0056] Furthermore, a detection window 12 is provided on the mounting base plate 1 and between the two guide rails 41 . The detection window 12 is used to avoid the clamping assembly 3 and the product 400 to be tested, so as to facilitate the installation and rotation of the product 400 to be tested and avoid interference with imaging.

[0057] See also Figure 1 and Figure 2 As shown, as an optional solution, the first clamping member 31 includes an active chuck 311, the second clamping member 32 includes a passive chuck 321, a driving motor 33 is arranged on the mounting base 1, the output shaft of the driving motor 33 faces the auxiliary support plate 2, the active chuck 311 is fixed on the output shaft of the driving motor 33, the passive chuck 321 is rotatably mounted on the auxiliary support plate 2, the active chuck 311 and the passive chuck 321 are coaxially arranged, and the two ends of the tested product 400 are clamped by the active chuck 311 and the passive chuck 321 respectively.

[0058] Therefore, the active chuck 311 cooperates with the passive chuck 321 to clamp the two ends of the product 400 under test, and then the driving motor 33 drives the active chuck 311 to rotate, thereby linking the product 400 under test to rotate, thereby meeting the needs of comprehensive testing.

[0059] See also Figure 3 and Figure 4 As shown, as another optional scheme, the first clamping member 31 includes a quick-release sleeve 312, the second clamping member 32 includes a rotating top 322, a driving motor 33 is arranged on the mounting base 1, the output shaft of the driving motor 33 faces the auxiliary support plate 2, the quick-release sleeve 312 is connected to the output shaft of the driving motor 33 through a coupling, the rotating top 322 is rotatably installed on the auxiliary support plate 2, the quick-release sleeve 312 and the rotating top 322 are coaxially arranged, one end of the tested product 400 is snap-connected with the quick-release sleeve 312, and the other end of the tested product 400 is tightened by the rotating top 322.

[0060] Thus, the quick-release sleeve 312 is used to quickly plug in one end of the product 400 under test, and then the rotating top 322 presses the other end of the product 400 under test to quickly fix the product 400 under test. The driving motor 33 then drives the quick-release sleeve 312 to rotate, thereby linking the product 400 under test to rotate, thereby meeting the needs of comprehensive testing.

[0064] The cone beam CT inspection carrier 100 is used for clamping the product 400 to be inspected;

[0065] The light pipe assembly 200 includes a ray source 210, which is used to emit X-rays to the product 400 under test;

[0066] The adjustment mechanism 300 is used to adjust the position of the cone-beam CT inspection carrier 100 relative to the light pipe assembly 200 .

[0067] Specifically, the adjustment mechanism 300 includes a mounting base 310 located on one side of the light tube assembly 200, a three-axis driver 320 is provided on the mounting base 310, and the cone-beam CT detection carrier tooling 100 is installed at the output end of the three-axis driver 320.

The radiation source 210 is installed on the transfer platform 220 with the radiation source facing upward, and the cone-beam CT detection carrier tooling 100 is located directly above the radiation source 210.

[0068] Therefore, the cone-beam CT detection device using the above-mentioned cone-beam CT detection carrier tooling 100 can make the product under test 400 perform xyz three-axis movement relative to the radiation source 210 through the adjustment mechanism 300, thereby realizing all-round detection and adjusting the imaging magnification, meeting more detection needs.
