Description

Technical Field

[0001] The utility model relates to the technical field of X-ray, in particular to an X-ray emitting device with a deflectable X-ray source. Background Art

[0002] Nondestructive testing refers to the use of changes in heat, sound, light, electricity, magnetism, etc. caused by abnormalities or defects in the internal structure of materials to detect materials by physical or chemical methods with the help of modern technologies and equipment without damaging or affecting the performance of the tested object and without harming the internal tissues of the tested object, on the premise of not damaging or affecting the performance of the tested object and not harming the internal tissues of the tested object.

[0003] With the rapid development of computer and microelectronics technologies, digital technologies, computer networks, and communication technologies have had a wide and profound impact on the field of X-ray imaging. Detection methods such as X-ray computed tomography (CT), 3D CT imaging, spiral CT imaging, digital radiography (DR), and 2D or 2.5D DR imaging have been widely used in industrial inspections, especially suitable for the inspections of industrial castings, die castings, and wheels. Since industrial X-ray inspections measure different tested objects with different materials, thicknesses, and densities, the test requirements are also different. High-voltage and high-current X-ray sources are used for metal test objects with relatively large density and thickness, while low-voltage micro-focus X-ray sources are used for fine and high magnification and high-definition resolution.

[0004] The existing Chinese patent (application number: CN202122405717.2) discloses a DR / CT detection system applicable to 2D / 2.5D / 3D, and its ray device and imaging device cannot deflect relative to the horizontal plane.

[0005] In addition, on a device that simultaneously has two-dimensional DR imaging and three-dimensional CT imaging, its ray source and flat panel detector can deflect up and down around their own axes as needed. For example, the existing Chinese patent (CN202311443715.X) discloses an X-ray imaging device, in which its ray source and detector can deflect up and down relative to the horizontal plane. However, the mounting brackets corresponding to its ray source or detector are not stable enough, and the mounting brackets cannot impose constraints on the ray source or detector. Summary of the Utility Model

[0006] In view of the above-mentioned disadvantages of the prior art, the technical problem to be solved by the present utility model is to provide an X-ray emitting device with a deflectable X-ray source, which can make the rigidity and strength of its own rotating frame stronger, can reliably restrict the deflection angle of the rotating frame relative to the vertical moving frame, and can better protect the X-ray source.

[0007] To solve the above technical problems, the present utility model provides an X-ray emitting device with a deflectable X-ray source, comprising:

[0008] A support frame disposed inside a shielding chamber;

[0009] A vertical moving frame movably arranged up and down on the support frame;

[0010] A rotating frame including a horizontal beam and a deflecting end plate. The cross-section of the horizontal beam is in a square shape with a hollow center. The deflecting end plate is vertically arranged at the end of the horizontal beam. Reinforcing ribs are provided between the deflecting end plate and the horizontal beam. A pin shaft is provided on the deflecting end plate, and the pin shaft rotatably penetrates through the vertical moving frame;

[0011] A deflection driver disposed between the pin shaft and the vertical moving frame, and the deflection driver is used to drive the deflecting end plate to rotate relative to the vertical moving frame;

[0012] A deflection limiting structure including two limiting blocks and a stop member. The two limiting blocks are arranged on the side wall of the deflecting end plate facing away from the horizontal beam, and the two limiting blocks are arranged at an angle. The stop member is arranged on the vertical moving frame and is located between the two limiting blocks;

[0013] An installation frame including a clamping and fixing assembly and a protective frame. The clamping and fixing assembly includes two clamping members symmetrically clamping on opposite sides of the horizontal beam, and the protective frame is fixedly connected to the two clamping members respectively;

[0014] An X-ray source including a main body and a panel provided on the main body. A transmission window is provided on the panel. The main body is located inside the protective frame, and the panel is detachably connected to the side of the protective frame away from the horizontal beam; the deflection angle range of the X-ray source with the horizontal plane as the reference plane is -30 degrees to 30 degrees.

[0015] Further, the stop member includes a stop screw and a fastening nut. The screw rod portion of the stop screw threadedly penetrates through the vertical moving frame. The screw head of the stop screw is in stop cooperation with the limiting block when the X-ray source deflects upward or downward to the limit position, and the fastening nut is threadedly sleeved on the screw rod portion of the stop screw to fasten the stop screw to the vertical moving frame.

[0016] Further, the clamping member includes a first plate, a second plate vertically arranged on the first plate, and a reinforcing rib provided between the first plate and the second plate. The first plate is fixedly connected to the horizontal beam, and the second plate is fixedly connected to the protective frame.

[0017] Further, the protective frame includes a bottom frame connected to the clamping and fixing assembly and two side frames symmetrically arranged on opposite sides of the bottom frame. An anti-deformation plate is provided between the side frame and the bottom frame, and the shape of the anti-deformation plate is adapted to the outer contour of the main body.

[0018] As described above, the X-ray source deflectable X-ray emitting device of the present utility model has the following beneficial effects: In the X-ray emitting device of the present utility model, the support frame mainly plays a supporting role. The vertical moving frame is arranged on the support frame so as to move up and down, so that the X-ray source can be at different heights. The rotating frame includes a horizontal beam and a deflecting end plate. The cross-section of the horizontal beam is in a square shape with a hollow center.

The two limit blocks are arranged on the side wall of the deflecting end plate facing away from the horizontal beam, and the two limit blocks are arranged at an angle. The stop member is arranged on the vertical moving frame and is located between the two limit blocks. When the deflecting end plate deflects upward to the limit position, a stop member abuts against one of the limit blocks. When the deflecting end plate deflects downward to the limit position, a stop member abuts against the other limit block. In order to better protect the X-ray source, the main body is located inside the protective frame, and the panel is detachably connected to the side of the protective frame away from the horizontal beam. Therefore, the X-ray source deflectable X-ray emitting device of the present utility model can make the rigidity and strength of its own rotating frame stronger, can reliably restrict the deflection angle of the rotating frame relative to the vertical moving frame, and can better protect the X-ray source.

A pin shaft 23 is arranged on the deflecting end plate 22, and the pin shaft 23 is rotatably penetrated through the vertical moving frame 1;

[0056] A deflection driver 3, which is arranged between the pin shaft 23 and the vertical moving frame 1, and the deflection driver 3 is used to drive the deflecting end plate 22 to rotate relative to the vertical moving frame 1;

[0057] A deflection limiting structure 4, which includes two limiting blocks 41 and a stop member 42.

[0060] In the X-ray emitting device of the present utility model, the support frame mainly plays a supporting role.
