Description

Technical Field

[0001] This utility model relates to the field of X-ray machine inspection devices, specifically an automatic inspection device for assisting in the maintenance of X-ray machine equipment. Background Technology

[0002] An X-ray machine is a device that uses high-voltage excited X-rays to penetrate objects and captures the absorption and attenuation distribution of the rays within the object due to density differences, thereby generating an image of the internal structure. It is widely used in medical diagnostics, industrial non-destructive testing, and security inspection. It is characterized by its non-invasive nature and rapid imaging capabilities, but strict radiation safety precautions must be taken when using it. Currently, existing X-ray machines in industrial X-ray flaw detection mainly rely on manual mobile inspection methods. Operators need to hold the equipment and adjust the three-dimensional spatial relationship between the X-ray emission source, the workpiece, and the imaging plate at close range. However, this process has drawbacks such as insufficient positioning accuracy leading to image distortion, safety risks of operators being exposed to scattered radiation environment for a long time, image ghosting caused by equipment vibration, and excessive time consumption due to repeated positioning of complex curved components. In view of this, the inventors urgently need to design an automatic inspection device to assist in the maintenance of X-ray machine equipment, so as to enable automated and precise control of the cabinet in multi-angle spatial positioning during X-ray flaw detection. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide an automatic detection device to assist in the maintenance of X-ray machine equipment, so as to solve the technical problem of the difficulty in adjusting the cabinet at multiple angles during X-ray machine flaw detection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic inspection device for assisting in the maintenance of X-ray machine equipment, comprising a housing and an operating table. A worktable is embedded inside the housing. A support plate for placing the cabinet to be inspected is provided at the top center of the worktable. A pair of longitudinal support blocks are symmetrically arranged on both sides of the support plate. A rotatable rotating rod is horizontally arranged at the symmetrical center of the inner wall of each longitudinal support block and passes through the support plate. A support frame is fixedly connected to the bottom of each longitudinal support block. A longitudinal rotating motor support frame is fixedly installed on the right outer wall of the support frame. A longitudinal rotating motor is fixedly mounted on the longitudinal rotating motor support frame. The output shaft of the longitudinal rotating motor passes through the corresponding longitudinal support block and is connected to one end of the rotating rod. The bottom of the support frame is connected to the output shaft of the horizontal rotating motor.

[0005] By adopting the above technical solutions, the layout design of the outer shell and the operating table achieves physical isolation between equipment operation and core structure. The outer shell provides dust and impact protection for internal precision components, while the operating table integrates a human-machine interface to reduce the threshold of use. The workbench, as a load-bearing base, decouples the vibration transmission path from the outer shell. The central layout of its top support plate ensures the stability of the center of gravity of the cabinet under maintenance. The longitudinal support blocks are symmetrically distributed on both sides of the support plate to form a double-point support structure, which, together with the horizontally inserted rotating rod, constitutes a torsional stiffness matrix to eliminate the risk of cabinet overturning.

[0006] Furthermore, two silicone suction cups are symmetrically embedded on the surface of the support plate. Each silicone suction cup includes a silicone nozzle, a lifting block, and a threaded rotating block. The silicone nozzle is fixedly connected to the top of the lifting block, and the lifting block is threadedly connected to the threaded rotating block via a threaded rod.

[0007] By adopting the above technical solution, two silicone suction cups symmetrically embedded on the surface of the support plate constitute an adsorption system. The material properties of the silicone suction nozzle simultaneously achieve elastic buffering and high friction adsorption, eliminating detection errors caused by cabinet displacement. The lifting block converts rotational motion into linear lifting through the helical pair of the threaded rod and the threaded rotating block, achieving millimeter-level fine adjustment of the suction nozzle height. When there are assembly tolerances on the bottom surface of the cabinet, the operator rotates the threaded rotating block to make the lifting block drive the silicone suction nozzle to rise or fall, ensuring that the two suction cups always evenly distribute the load.

[0008] Furthermore, a horizontal rotating motor support block is fitted onto the outer wall of the horizontal rotating motor.

[0009] By adopting the above technical solution, the circumferential constraint of the horizontal rotating motor support block on the horizontal rotating motor significantly suppresses the radial runout of the output shaft, and the vibration energy of the motor housing is dissipated through the metal matrix of the support block.

[0010] Furthermore, a lifting support block is fixedly connected to the bottom of the horizontal rotating motor support block, and the lifting support block has multiple lifting cavities inside.

[0011] By adopting the above technical solution, the rigid connection between the horizontal rotating motor support block and the lifting support block forms a load transmission channel, converting the rotational torque into the axial driving force of the lifting support block.

[0012] Furthermore, a lead screw is vertically installed in the central cavity of the lifting support block, and the outer wall of the lead screw is threaded. Three limiting rods are vertically and equidistantly distributed around the lead screw inside the lifting support block.

[0013] By adopting the above technical solution, the lead screw and external thread of the central cavity of the lifting support block form a precision helical pair, and three limit rods are distributed equidistantly around the lead screw to construct a three-point guide system. When the lead screw drives the load to lift, the limit sleeve slides along the limit rod to eliminate radial clearance.

[0014] Furthermore, the bottoms of both the lead screw and the limiting rod are fixed to the upper surface of the base, and the base is fixedly installed to the bottom of the inner cavity of the outer shell by bolts.

[0015] By adopting the above technical solution, the design of fixing the bottom of the lead screw and the limiting rod together to the upper surface of the base forms an integral pre-tightening structure. When the lead screw is subjected to axial tension, the tension is evenly distributed to the three limiting rods through the base, avoiding stress concentration in a single rod.

[0016] Furthermore, an outer sleeve is fixed to the bottom of the lifting support block, and a rotating block is sleeved on the inner wall of the outer sleeve. The inner wall of the rotating block is engaged with the thread on the lead screw. Three connecting rods are fixedly connected circumferentially at equal intervals on the outer wall of the outer sleeve. The other ends of the three connecting rods are respectively fixedly connected to the limiting sleeve. The limiting sleeve is slidably sleeved on the outer wall of the corresponding limiting rod.

[0017] By adopting the above technical solution, the outer sleeve at the bottom of the lifting support block and the sleeve of the rotating block form a double-sealed cavity. The engagement between the inner thread of the rotating block and the lead screw adopts a variable engagement angle design. When moving upward, the engagement increases the driving force, and when moving downward, the engagement achieves a smooth and slow descent.

[0018] Furthermore, a lead screw motor is embedded in the center of the base, and the output axis of the lead screw motor extends upward and is connected to the bottom of the lead screw.

[0019] By adopting the above technical solution, the structural design of embedding the lead screw motor in the center of the base achieves a high degree of integration of the drive system. By placing the power source directly at the bottom of the lifting mechanism, the power transmission chain of the lead screw is significantly shortened.

[0020] In summary, the present invention has the following main advantages: This utility model isolates external interference through the outer shell while integrating human-machine interaction on the operating table. The top support plate of the workbench supports the cabinet in the center to ensure the stability of the center of gravity. Symmetrical longitudinal support blocks and rotating rods form an anti-overturning support structure. The longitudinal rotation motor drives the rotating rod through the support frame to realize the pitch of the cabinet. At the same time, the bottom of the support frame is directly connected to the output shaft of the horizontal rotation motor, forming a dual-degree-of-freedom drive of longitudinal and horizontal rotation. The longitudinal rotation motor controls the cabinet to rotate around the horizontal axis, and the horizontal rotation motor drives the entire mechanism to rotate around the vertical axis through the support frame, ultimately realizing the precise three-dimensional spatial orientation of the cabinet. This invention utilizes a support plate with dual silicone suction cups and a threaded lifting mechanism for leveling, eliminating the influence of cabinet assembly tolerances. A horizontal rotating motor enhances stability via a support block. A lead screw and a limit rod form the lifting core, with the lead screw providing axial driving force and the limit rod constraining radial offset. The base fixing structure evenly distributes the load, while the rotating block at the bottom of the lifting support block engages with the lead screw. Three sets of connecting rods are linked, and the limit sleeve moves synchronously along the limit rod, preventing uneven load jamming. The lead screw motor is built into the base to directly drive the lead screw, shortening the transmission chain and improving accuracy. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] In this embodiment: An automatic detection device for assisting in the maintenance of X-ray machine equipment, such as Figure 1-4As shown, the device includes an outer casing 1 and an operating platform 2. A workbench 3 is embedded inside the outer casing 1. A support plate 5 for placing the cabinet to be inspected is located at the top center of the workbench 3. A pair of longitudinal support blocks 7 are symmetrically arranged on both sides of the support plate 5. A rotatable rotating rod 10 is horizontally arranged at the symmetrical center of the inner wall of each longitudinal support block 7 and passes through the support plate 5. A support frame 11 is fixedly connected to the bottom of each longitudinal support block 7. A longitudinal rotary motor support frame 9 is fixedly fixed to the right outer wall of the support frame 11. A longitudinal rotary motor 8 is fixedly mounted on the longitudinal rotary motor support frame 9. The output shaft of the longitudinal rotary motor 8 passes through the corresponding longitudinal support block 7 and is connected to one end of the rotating rod 10. The bottom of the support frame 11 is connected to the output shaft of a horizontal rotary motor 16. The layout design of the outer casing 1 and the operating platform 2 achieves physical isolation between the equipment operation and the core structure. The outer casing 1 is the internal... Precision components are protected against dust and impact. The control panel 2 integrates a human-machine interface to lower the barrier to entry. The workbench 3, as the load-bearing base, decouples the vibration transmission path from the outer shell 1. The centrally positioned top support plate 5 ensures the stability of the center of gravity of the cabinet under maintenance. The longitudinal support blocks 7 are symmetrically distributed on both sides of the support plate 5 to form a double-point support structure, which, together with the horizontally inserted rotating rod 10, constitutes a torsional stiffness matrix, eliminating the risk of cabinet tipping. At the same time, the support frame 11, as a load-bearing skeleton, transmits the installation reaction force of the longitudinal rotary motor 8 to the bottom through the longitudinal rotary motor support frame 9. The direct connection design between the output shaft of the horizontal rotary motor 16 and the bottom of the support frame 11 realizes the synthesis of two degrees of freedom of motion. The longitudinal rotary motor 8 drives the cabinet to pitch around the horizontal axis through the rotating rod 10, while the horizontal rotary motor 16 drives the entire support frame 11 to rotate around the vertical axis, enabling the cabinet to be precisely oriented in three-dimensional space.

[0025] See Figure 2 , Figure 3 , Figure 4 Two silicone suction cups 6 are symmetrically embedded on the surface of the support plate 5. Each silicone suction cup 6 includes a silicone nozzle, a lifting block, and a threaded rotating block. The silicone nozzle is fixedly connected to the top of the lifting block, and the lifting block is threadedly connected to the threaded rotating block via a threaded rod. The two silicone suction cups 6 symmetrically embedded on the surface of the support plate 5 constitute an adsorption system. The material properties of the silicone nozzle simultaneously achieve elastic buffering and high-friction adsorption, eliminating detection errors caused by cabinet displacement. At the same time, the lifting block converts rotational motion into linear lifting through the helical pair between the threaded rod and the threaded rotating block, achieving millimeter-level fine adjustment of the nozzle height. When there are assembly tolerances on the bottom surface of the cabinet, the operator rotates the threaded rotating block to make the lifting block drive the silicone nozzle to rise or fall, ensuring that the load is evenly distributed between the two suction cups.

[0026] See Figure 2 , Figure 3The outer wall of the horizontal rotary motor 16 is fitted with a horizontal rotary motor support block 12. The circumferential constraint of the horizontal rotary motor 16 by the horizontal rotary motor support block 12 significantly suppresses the radial runout of the output shaft, so that the vibration energy of the motor housing is dissipated through the metal matrix of the horizontal rotary motor support block 12. At the same time, the dual effect enables the horizontal rotary motor 16 to maintain a small speed fluctuation during continuous angle adjustment, and eliminates the concentricity deviation of the support frame 11 caused by the thermal deformation of the motor.

[0027] See Figure 2 , Figure 3 The bottom of the horizontal rotating motor support block 12 is fixedly connected to the lifting support block 13. The lifting support block 13 has multiple lifting cavities inside. The rigid connection between the horizontal rotating motor support block 12 and the lifting support block 13 forms a load transmission channel, which converts the rotational torque into the axial driving force of the lifting support block 13. At the same time, the multiple lifting cavities inside the lifting support block 13 constitute a distributed pressure balance system. When the equipment is subjected to asymmetrical load, the cavities automatically compensate for the pressure difference through interconnection.

[0028] See Figure 2 , Figure 3 , Figure 4 A lead screw 15 is vertically installed in the central cavity of the lifting support block 13. The outer wall of the lead screw 15 is threaded. Three limiting rods 14 are vertically and equidistantly arranged around the lead screw 15 inside the lifting support block 13. The lead screw 15 in the central cavity of the lifting support block 13 and the external thread form a precision helical pair. The three limiting rods 14 are equidistantly arranged around the lead screw 15 to form a three-point guide system. When the lead screw 15 drives the load to lift, the limiting sleeve 19 slides along the limiting rod 14 to eliminate radial clearance. At the same time, the angular displacement of the lifting support block 13 is constrained by the principle of triangle stability.

[0029] See Figure 2 , Figure 3 The bottoms of the lead screw 15 and the limiting rod 14 are both fixed to the upper surface of the base 4. The base 4 is fixed to the bottom of the inner cavity of the outer shell 1 by bolts. The design of the bottoms of the lead screw 15 and the limiting rod 14 being fixed to the upper surface of the base 4 forms an integral pre-tightening structure. When the lead screw 15 is subjected to axial tension, the tension is evenly distributed to the three limiting rods 14 through the base 4 to avoid stress concentration in a single rod. At the same time, after the base 4 is fixed to the bottom of the inner cavity of the outer shell 1 by bolts, the shock-absorbing layer absorbs the vibration energy of the equipment. The upper surface of the base 4 provides a vertical installation reference for the lead screw 15, preventing jamming caused by uneven foundation.

[0030] See Figure 2 , Figure 3 , Figure 4The bottom of the lifting support block 13 is fixed with an outer sleeve 20. The inner wall of the outer sleeve 20 is fitted with a rotating block 21. The inner wall of the rotating block 21 meshes with the thread on the lead screw 15. Three connecting rods 18 are fixedly connected circumferentially at equal intervals on the outer wall of the outer sleeve 20. The other ends of the three connecting rods 18 are respectively fixedly connected to the limiting sleeve 19. The limiting sleeve 19 is slidably fitted on the outer wall of the corresponding limiting rod 14. The fit between the outer sleeve 20 at the bottom of the lifting support block 13 and the rotating block 21 forms a double-sealed cavity. The meshing of the inner thread of the rotating block 21 with the lead screw 15 adopts a variable engagement angle design. When moving upward, the engagement increases the driving force, and when moving downward, the engagement achieves a smooth and slow descent. At the same time, the three connecting rods 18 rigidly connect the outer sleeve 20 and the limiting sleeve 19, so that the three sets of limiting mechanisms form a linkage frame. When the lead screw 15 drives the lifting support block 13 to move, the limiting sleeve 19 slides along the limit rod 14 in strict synchronization, eliminating structural deflection during the lifting process.

[0031] See Figure 2 , Figure 3 The center of the base 4 is fitted with a lead screw motor 17. The output shaft of the lead screw motor 17 extends upward and is connected to the bottom of the lead screw 15. The structural design of the lead screw motor 17 being embedded in the center of the base 4 realizes the high integration of the drive system. By placing the power source directly at the bottom of the lifting mechanism, the power transmission chain of the lead screw 15 is significantly shortened. At the same time, the direct connection structure between the motor output shaft and the bottom of the lead screw 15 completely eliminates the intermediate links in the traditional transmission, greatly reducing mechanical energy loss.

[0032] The implementation principle of this embodiment is as follows: After the cabinet to be inspected is placed on the support plate 5 on top of the workbench 3, its bottom surface is fixed by two symmetrically embedded silicone suction cups 6. The operator rotates the threaded rotating block to drive the lifting block, so that the silicone suction nozzles are independently leveled according to the height difference of the bottom surface of the cabinet. At this time, the longitudinal support blocks 7 on both sides of the support plate 5 form an anti-torsional support frame through the through-fitting of the rotating rod 10. Under the drive of the longitudinal rotating motor 8 and the longitudinal rotating motor support frame 9, the rotating rod 10 drives the cabinet to pitch around the horizontal axis. At the same time, the output shaft of the horizontal rotating motor 16 drives the support frame 11, so that the support frame 11 and its upper structure rotate around the vertical axis, thereby realizing the rotation of the cabinet. Horizontal orientation adjustment and vertical position adjustment are achieved by a lead screw system. The lead screw motor 17 built into the base 4 drives the lead screw 15 to rotate. The rotating block 21, which is threadedly engaged with the lead screw 15, rotates and rises and falls within the outer sleeve 20, driving the entire mechanism fixed to the bottom of the lifting support block 13 to move vertically. During the lifting process, three circumferentially distributed limit rods 14 constrain the radial offset of the lifting support block 13 through the limit sleeve 19. At the same time, three sets of connecting rods 18 rigidly link the outer sleeve 20 and the limit sleeve 19 to ensure the coaxial accuracy of the vertical movement. Finally, the structure of the base 4 fixed to the bottom of the inner cavity of the outer shell 1 stably transmits the load of the whole machine to the base platform, completing the precise positioning of the cabinet in three-dimensional space.
