It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0021] In the specific embodiments, various specific technical features described can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of various specific technical features in the present application are not described again.

It should be understood that the terms "upper", "lower", "outer", "inner" refer to the position of the object in the normal use state, and the terms "left" and "right" refer to the left and right directions shown in the specific corresponding schematic diagram, which can be the left and right directions in the normal use state or not.

[0023] It should be noted that the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitation, the element defined by the sentence "including one" does not exclude the existence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0024] In the description of the present application, the "first direction", "second direction", orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, wherein the "first direction" is the direction indicated by the arrow L1 in the drawings, and the "second direction" is the direction indicated by the arrow L2 in the drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0025] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the technical term "contact" should be understood in a broad sense, which can be direct contact or contact through an intermediate medium layer, and can be contact between two objects in contact without interaction force or contact between two objects in contact with interaction force.

[0026] Embodiments of the present application provide an assembly device for an X-ray tube. In order to facilitate understanding, the X-ray tube provided in the related art in the field will be introduced first.

[0027] The X-ray tube is an oil circulation cooling assembly composed of a tube core, a tube sleeve and the like. The tube sleeve usually includes a center tube sleeve and a cathode tube sleeve, the cathode tube sleeve is sleeved in the center tube sleeve, and the two form an installation space for installing the tube core, the installation space is filled with insulating oil and surrounds the tube core to form an insulating and cooling environment.

[0028] When the X-ray tube is working, the internal insulating oil can reach a temperature of 80℃ or higher. If the sealing between the cathode tube sleeve and the center tube sleeve is not good, air may enter to form air bubbles, causing high-voltage sparking. In addition, if the sealing is not good, insulating oil may seep out during scanning, causing personnel burns. In summary, the sealing between the center tube sleeve and the cathode tube sleeve is crucial for the X-ray tube.

[0029] As an example, in the related art, a sealing ring is used to seal between the cathode tube sleeve and the center tube sleeve. In the actual assembly process, the sealing ring needs to be sleeved in the sealing groove of the cathode tube sleeve along the axial direction, and then the cathode tube sleeve is pressed into the center tube sleeve to form an interference fit between the cathode tube sleeve and the center tube sleeve.

[0030] In the application, a relatively large force is required to assemble the cathode tube sleeve, and usually 2-3 persons are required to complete the assembly, which is inconvenient. On the other hand, in the assembly process, the force on the cathode tube sleeve in each direction should be balanced as much as possible, so that the sealing ring is fully and uniformly extruded, thereby achieving better sealing effect. However, it is difficult to balance the force in the manual assembly, especially in the case of multiple persons. In addition, the cathode tube sleeve should be vertically inserted into the center tube sleeve in the assembly process to reduce the possibility of the cathode tube sleeve touching the glass structure on the tube core and causing the tube core to be scrapped.

[0031] To solve the above problems, the application provides an X-ray tube assembly device. It should be noted that the X-ray tube assembly device provided by the application can be applied to the assembly of any X-ray tube including a center tube sleeve and a cathode tube sleeve, and is not limited to the exemplary X-ray tube given above.

[0032] With reference to Figure 1 and Figure 2 , the X-ray tube assembly device provided by the application includes a base 1, a first fixing member 2, a second fixing member 3, and a power mechanism 4.

[0033] The specific structure of the base 1 is not limited, and the first fixing member 2 and the second fixing member 3 are arranged along a first direction on the base 1.

[0034] The first fixing member 2 and the second fixing member 3 are respectively used to connect with the cathode tube sleeve A and the center tube sleeve B. The first fixing member 2 can be connected with the cathode tube sleeve A, and the second fixing member 3 can be connected with the center tube sleeve B. Alternatively, the first fixing member 2 can be connected with the center tube sleeve B, and the second fixing member 3 can be connected with the cathode tube sleeve A. In the following description, the first fixing member 2 is connected with the cathode tube sleeve A, and the second fixing member 3 is connected with the center tube sleeve B.

[0035] The specific structure of the first fixing member 2 and the second fixing member 3 is not limited, as long as it can be connected with the cathode tube sleeve A and the center tube sleeve B.

[0036] The power mechanism 4 is arranged on the base 1, and the first fixing member 2 is connected to the output end of the power mechanism 4. The first fixing member 2 and the second fixing member 3 are distributed along the first direction, and the power mechanism 4 is used to drive the first fixing member 2 to move along the first direction relative to the second fixing member 3.

[0037] Here, the first direction can be any direction, and as an example, the first direction is the direction of gravity. In actual use, the first direction is parallel to the axis of the cathode tube sleeve A and the center tube sleeve B, in other words, the first direction is parallel to the assembly direction of the cathode tube sleeve A and the center tube sleeve B.

[0038] The specific structure of the power mechanism 4 is not limited, as long as it can drive the first fixing member 2 to move relative to the second fixing member 3 in the first direction. For example, the power mechanism 4 can include a power member such as an electric cylinder, a pneumatic cylinder 41, an oil cylinder, or a motor.

[0039] For example, in the actual use process, the cathode tube sleeve A can be connected to the first fixing member 2, and the center tube sleeve B can be connected to the second fixing member 3, and then the power mechanism 4 is controlled to drive the first fixing member 2 to move in the first direction towards the second fixing member 3, so as to realize the installation of the cathode tube sleeve A and the center tube sleeve B. Alternatively, the power mechanism 4 can be controlled to drive the first fixing member 2 to move in the first direction away from the second fixing member 3, so as to realize the disassembly of the cathode tube sleeve A and the center tube sleeve B.

[0040] It should be noted that the power mechanism 4 can be configured to only drive the first fixing member 2 to move in the first direction towards the second fixing member 3, or to only drive the first fixing member 2 to move in the first direction away from the second fixing member 3, or to both drive the first fixing member 2 to move in the first direction towards the second fixing member 3 and to move in the first direction away from the second fixing member 3. Those skilled in the art can determine the specific configuration according to the actual use requirements.

[0041] The power mechanism 4 is provided in the assembling device of the X-ray tube of the embodiment to drive the first fixing member 2 to move relative to the second fixing member 3 in the first direction, so that the installation or disassembly of the center tube sleeve B and the cathode tube sleeve A can be completed by the force provided by the power mechanism 4, saving manpower. At the same time, compared with manual assembly, the force provided by the power mechanism 4 can be relatively uniformly distributed on the cathode tube sleeve A and the center tube sleeve B, improving the assembly sealing between the two, and improving the stability of the movement direction of the cathode tube sleeve A and / or the center tube sleeve B during installation or disassembly, thereby reducing the possibility of damage to the tube core caused by contact between the cathode tube sleeve A and the tube core.

[0042] In some embodiments, the power mechanism 4 specifically includes a pneumatic cylinder 41, and the first fixing member 2 is connected to the output end of the pneumatic cylinder 41. The advantage of using the pneumatic cylinder 41 to provide power is that the cost is relatively low and the power provided is relatively stable. Of course, in some other embodiments, the power mechanism 4 can also use, for example, an electric cylinder, an oil cylinder, a motor, etc. to provide power.

[0043] In the embodiment, the specific structure of the pneumatic cylinder 41 is not limited, for example, the pneumatic cylinder 41 includes a piston rod and a cylinder barrel, and the output end of the pneumatic cylinder 41 can specifically refer to one end of the piston rod of the pneumatic cylinder 41 extending out of the cylinder barrel. The specific connection manner of the first fixing member 2 and the output end of the pneumatic cylinder 41 is not limited, which can be, for example, clamping, threaded connection, welding, etc.

[0044] In some embodiments, the cylinder 41 is a double-acting cylinder, which specifically refers to a cylinder capable of outputting power in two directions. In this way, by changing the power output direction of the cylinder 41, the driving of the first fixed part 2 to move towards or away from the second fixed part 3 in the first direction can be achieved, and thus the assembly equipment of the X-ray tube can be applied to both the installation and disassembly of the center tube sleeve B and the cathode tube sleeve A. Of course, in some other embodiments, the cylinder 41 can also be a single-acting cylinder 41.

[0045] In some embodiments, the power mechanism 4 further comprises a gas source assembly 42 connected to the cylinder 41 and a switch part 43 connected to the gas source assembly 42. In this way, during actual operation, the operator can control the movement of the cylinder 41 by operating the switch part 43 to complete the assembly operation, which can improve the operation efficiency and reduce the control cost.

[0046] The specific structure of the gas source assembly 42 is not limited. Taking the case that the cylinder 41 is a double-acting cylinder, the gas source assembly 42 can include a gas pump 421, a first gas pipe 422, and a second gas pipe 423, and the first gas pipe 422 and the second gas pipe 423 are both connected to the gas pump 421 and the cylinder 41. Specifically, the cylinder barrel of the cylinder 41 can be divided into two cavities by the piston rod, and the first gas pipe 422 and the second gas pipe 423 are respectively connected to the two cavities. During actual use, the gas pump 421 can ventilate the first gas pipe 422 to exhaust the second gas pipe 423, thereby driving the piston rod to move to one side of the first direction, or the gas pump 421 can ventilate the second gas pipe 423 to exhaust the first gas pipe 422, thereby driving the piston rod to move to the other side of the first direction.

[0047] The specific structure of the switch part 43 is not limited, which can be a press switch, a dial switch, a capacitive touch switch, etc. The specific position of the switch part 43 is not limited, which can be set at a position convenient for the operator to touch, for example, set on the base 1 and exposed to the outer surface of the base 1.

[0048] Taking the case that the gas source assembly 42 includes the first gas pipe 422 and the second gas pipe 423, the user can control the gas pump 421 to intake air into the first gas pipe 422 or the second gas pipe 423 by operating the switch part 43.

[0049] In some embodiments, the first fixed part 2 and / or the second fixed part 3 includes a connecting flange 21 and a fixing bolt 22, the axial direction of the connecting flange 21 is parallel to the first direction, and the fixing bolt 22 is used to connect the connecting flange 21 with the cathode tube sleeve A or the center tube sleeve B.

[0050] It can be understood that the cathode tube sleeve A and the center tube sleeve B are both cylindrical structures, and the advantage of connecting at least one of them with the connecting flange 21 is to help improve the stability of the connection, thereby improving the stability of the relative position of the two during the installation / dismounting process, and further reducing the possibility of damage to the tube core caused by the contact between the cathode tube sleeve A and the tube core.

[0051] In this embodiment, the first fixing member 2 and the second fixing member 3 can each include a connecting flange 21 and a fixing bolt 22. Alternatively, one of the first fixing member 2 and the second fixing member 3 can include a connecting flange 21 and a fixing bolt 22, and the other can adopt other structural forms, for example, the first fixing member 2 can include a connecting flange 21 and a fixing bolt 22, and the second fixing member 3 can include a clamping structure, a receiving groove, or other structures that can achieve connection with the cathode tube sleeve A or the center tube sleeve B.

[0052] In some embodiments, the fixing bolt 22 can be a hand screw, so that the connection difficulty can be reduced.

[0053] In some embodiments, the first fixing member 2 is detachably connected with the power mechanism 4. In this way, during actual use, different specifications of the first fixing member 2 can be installed on the power mechanism 4 to achieve the fixation of X-ray tubes of different specifications and improve the versatility of the X-ray tube assembly equipment.

[0054] Similarly, in some embodiments, the second fixing member 3 can be detachably connected with the base 1.

[0055] In some embodiments, referring to Figure 1 and Figure 2 , the X-ray tube assembly equipment further includes a first connecting member 5, which movably connects the power mechanism 4 with the base 1.

[0056] It can be understood that during the actual assembly process, the cathode tube sleeve A and the center tube sleeve B need to be connected to the first fixing member 2 and the second fixing member 3, respectively, and there may be interference during this connection process, resulting in an increase in the operation difficulty. In this embodiment, the first connecting member 5 movably connects the power mechanism 4 with the base 1, so that the first fixing member 2 can obtain a larger range of motion by adjusting the relative position of the power mechanism 4 and the base 1, thereby providing more operating space for the operator and reducing the operation difficulty of the operator when connecting the cathode tube sleeve A and the center tube sleeve B to the first fixing member 2 and the second fixing member 3.

[0057] On the other hand, the movably connecting the power mechanism 4 with the base 1 also helps to improve the flexibility of the relative position adjustment between the first fixing member 2 and the second fixing member 3, thereby helping to improve the adaptability of the assembly equipment to X-ray tubes of different specifications.

[0058] In the embodiment, the specific structure of the first connecting member 5 is not limited, and as an example, the first connecting member 5 can be rotationally connected and / or slidingly connected with the base 1 and the power mechanism 4.

[0059] In some embodiments, specifically referring to Figure 2 , the first connecting member 5 includes a rotating column 51 and a connecting arm 52, the rotating column 51 is connected with the base 1 and can rotate around the axis of the first direction relative to the base 1, the connecting arm 52 is connected to one end of the rotating column 51 away from the base 1 and the extension direction of the connecting arm 52 intersects with the first direction, and the power mechanism 4 is connected to the connecting arm 52.

[0060] As an example, the extension direction of the connecting arm 52 is perpendicular to the first direction. The connection mode of the connecting arm 52 and the rotating column 51 is not limited, which can be clamping, welding, threaded connection, etc.

[0061] In the embodiment, the power mechanism 4 can rotate around the axis of the first direction relative to the base 1, when connecting the cathode tube sleeve A and the center tube sleeve B to the first fixing member 2 and the second fixing member 3, if interference occurs, the first fixing member 2 and the second fixing member 3 can be staggered in the first direction by rotating the power mechanism 4, and after the connection is completed, the first fixing member 2 and the second fixing member 3 are aligned in the first direction by rotating the power mechanism 4.

[0062] In some embodiments, referring to Figure 2 , the first connecting member 5 includes a bearing 53, the rotating column 51 is rotationally connected with the base 1 through the bearing 53, so that the stability of the rotation of the rotating column 51 can be improved.

[0063] In some embodiments, the bearing 53 has a flange surface 53a, at least one threaded hole is formed on the flange surface 53a, the first connecting member 5 includes at least one first screw 54, the first screw 54 passes through the threaded hole on the flange surface 53a and is connected with the base 1, so that the stability of the connection between the bearing 53 and the base 1 is improved.

[0064] In some embodiments, the first connecting member 5 includes a pressing block 55 and at least one second screw 56, the connecting arm 52 abuts against the side surface of the rotating column 51 away from the base 1, the pressing block 55 abuts against the side surface of the connecting arm 52 away from the rotating column 51, and the second screw 56 passes through the pressing block 55, the connecting arm 52 and the rotating column 51 in sequence, so as to fix the three. Such a connection mode helps to improve the stability of the connection between the connecting arm 52 and the rotating column 51, and reduces the possibility of relative rotation between the two.

[0065] In some embodiments, the assembling device of the X-ray tube further includes a limiting member 6 for limiting the rotation of the rotating column 51 relative to the base 1.

[0066] It can be understood that, in order to improve the success rate of assembly, the axes of the cathode tube sleeve A and the center tube sleeve B need to be aligned during assembly, that is, the first fixing member 2 and the second fixing member 3 need to be aligned in the first direction during the action of the power mechanism 4, and for this purpose, the limiting member 6 is further added in the embodiment, which helps to reduce the possibility of rotation of the power mechanism 4 relative to the base 1 during the action, and thus helps to improve the success rate of assembly.

[0067] In the embodiment, the specific structure of the limiting member 6 is not limited, as long as it can achieve the effect of limiting the rotation of the rotating column 51 relative to the base 1.

[0068] In some embodiments, referring to Figure 2 , the limiting member 6 can specifically include at least one first limiting block 61 and at least one second limiting block 62, the first limiting block 61 protrudes from the circumferential surface of the rotating column 51, and the second limiting block 62 protrudes from the side surface of the base 1 facing the rotating column 51, the first limiting block 61 can abut against the second limiting block 62 along the side surface of the rotating column 51 in the circumferential direction, thereby limiting the rotation of the rotating column 51 relative to the base 1.

[0069] In the embodiment, specifically, the first limiting block 61 and the second limiting block 62 can be arranged such that when the first limiting block 61 abuts against the second limiting block 62, the first fixing member 2 and the second fixing member 3 are aligned in the first direction.

[0070] The specific number of the first limiting block 61 and the second limiting block 62 is not limited, and it can be understood that the number of the first limiting block 61 and the second limiting block 62 determines the angle range of the rotation of the rotating column 51 relative to the base 1, which can be specifically determined by the actual use requirement. The first limiting block 61 and the second limiting block 62 can be arranged one-to-one, or can not be arranged one-to-one. In a specific embodiment, the number of the first limiting block 61 and the second limiting block 62 can both be two, and the first limiting block 61 and the second limiting block 62 are both symmetrically distributed relative to the rotation axis of the rotating column 51.

[0071] In the embodiment, this arrangement of the limiting member 6 helps to quickly position the rotating position of the power mechanism 4, and improves the operation efficiency of the operator. On the other hand, it also helps to reduce the cost.

[0072] In some embodiments, referring to Figure 1 , the assembly equipment of the X-ray tube includes a second connecting member 7, which movably connects the second fixing member 3 and the base 1.

[0073] Similar to the first connecting member 5, the second connecting member 7 can make the second fixing member 3 movable relative to the base 1, so that on the one hand, it can provide more operation space for the operator, and reduce the operation difficulty of the operator when connecting the cathode tube sleeve A and the center tube sleeve B to the first fixing member 2 and the second fixing member 3. On the other hand, it is also helpful to improve the adaptation ability of the assembly equipment to X-ray tubes of different specifications.

[0074] In some embodiments, specifically, the second connecting member 7 includes a fixed part 71 and a movable part 72, the fixed part 71 is arranged on the base 1, and the movable part 72 is movable relative to the fixed part 71 along a second direction, the second direction is perpendicular to the first direction, and the second fixing member 3 is arranged on the movable part 72.

[0075] In the embodiment, the structure of the fixed part 71 and the movable part 72 is not limited, as long as the relative movement along the second direction can be realized.

[0076] As mentioned above, in some embodiments, the first connecting member 5 rotatably connects the power mechanism 4 and the base 1, in such embodiments, the second connecting member 7 and the first connecting member 5 cooperate with each other, which can further improve the flexibility of the relative position adjustment between the first fixing member 2 and the second fixing member 3, thereby further improving the adaptation ability of the assembly equipment to X-ray tubes of different specifications.

[0077] It should be noted that the specific structures of the first connecting member 5 and the second connecting member 7 mentioned in the above embodiments can be replaced with each other, that is, the first connecting member 5 can include the movable part 72 and the fixed part 71, and the power mechanism 4 can be connected to the fixed part 71. The second connecting member 7 can include the rotating column 51 and the connecting arm 52, and the second fixing member 3 is connected to the connecting arm 52.
