Description

Technical Field

[0001] This application relates to the field of bearing testing equipment technology, and in particular to a high-temperature bearing testing device for CT scanner X-ray tubes. Background Technology

[0002] A CT tube is an important component of a computed tomography (CT) scanner. Also known as an X-ray tube or emission tube, it is an electronic device that emits high-energy X-rays through an electron beam to perform tomographic scanning of the human body, thereby obtaining three-dimensional images of the inside of the body. The main components of a CT tube include the cathode, anode, focusing electrode, and spiral coil. The cathode and anode are the two most important parts of the CT tube. The bearings of the CT tube need to undergo high-temperature resistance testing before leaving the factory.

[0003] Existing technologies typically employ manual clamping and fixed heating plates, requiring manual adjustment of the clamping position and manual proximity to the heating plate, resulting in cumbersome operation, long processing time, and difficulty in ensuring heating uniformity.

[0004] Cooling is achieved using cooling water, which tends to remain on the bearing surface, requiring manual retrieval or wiping. This not only increases operational complexity but also poses safety hazards (such as the risk of slipping) and the residual water droplets may contaminate the testing environment. Summary of the Invention

[0005] The purpose of this application is to provide a high-temperature bearing testing device for CT scanner tubes in order to solve the above problems. It adopts an automated heating and cooling structure, which can complete the heating and avoidance operations without manual intervention. It adopts an annular air duct cooling design that is adapted to the bearing size to ensure that the airflow evenly covers the bearing surface, avoids the diffusion and waste of cooling airflow, and improves cooling efficiency.

[0006] This application achieves the above objectives through the following technical solutions:

[0007] A high-temperature bearing testing device for CT scanner X-ray tubes includes: a base providing support; a rotary conveyor for transporting materials via rotation; multiple circular pads detachably arranged along the circumference of the rotary disc; an electromagnetic heater for heating the bearing placed on the circular pads via heating tubes, the electromagnetic heater being connected to a drive unit capable of lifting and lowering; a second bracket fixedly connected to the base for providing support; a fan fixedly mounted on the second bracket with its outlet facing downwards towards the circular pads; an air guide duct arranged along the outlet of the fan to surround the outlet and guide airflow toward the bearing; an air guide shroud located at the center of the air guide duct, with a gap between the outer wall of the air guide shroud and the inner wall of the air guide duct to form an annular air duct adapted to the size of the bearing; and a connecting frame, the top of the air guide shroud being fixedly connected to the air guide duct via the connecting frame.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] like Figure 1-4 As shown, a high-temperature bearing testing device for CT scanner X-ray tubes includes: a base 1 providing support; a turntable conveyor 2 for transporting materials via rotation (the turntable conveyor 2 is existing technology); multiple circular pads 3 detachably arranged along the circumference of the turntable, which can simultaneously support bearings to allow for simultaneous loading and unloading and improve heating efficiency; an electromagnetic heater 9 for heating the bearings placed on the circular pads 3 via heating tubes, the electromagnetic heater 9 being connected to a drive unit capable of lifting and lowering, allowing the heating tubes of the 9 to be positioned outside or away from the bearing; a second bracket 16 fixedly connected to the base 1 for providing support; and a fan 17 fixedly mounted on the second bracket 16 with its outlet facing downwards towards the circular pads 3 (the fan 17 is existing technology and has rotating blades to generate airflow).

[0027] like Figure 4As shown, the air guide duct 18 is arranged along the air outlet of the fan 17 to surround the air outlet of the fan 17 and guide the airflow towards the bearing. The air guide duct 18 is fixedly connected to the fan 17 to improve sealing and prevent airflow leakage, ensuring that the air guide duct 18 guides the airflow towards the bearing. The air guide cover 19 is located inside the center of the air guide duct 18, and there is a gap between the outer wall of the air guide cover 19 and the inner wall of the air guide duct 18 to form an annular air duct that matches the size of the bearing. The annular air duct can guide the airflow to the bearing in an annular shape, avoiding waste caused by airflow diffusion. The connecting frame 20 is fixedly connected to the air guide duct 18 at the top of the air guide cover 19. The connecting frame 20 has a cross-shaped structure, and its end is fixedly connected to the air guide duct 18 to support the air guide cover 19. The cross-shaped structure can avoid affecting the flow of airflow.

[0028] In some embodiments, the drive unit includes: a first bracket 6, fixedly connected to the base 1 to provide support; a rocker 7, with a support shaft 8 fixedly connected between its two ends, and the rocker 7 is rotatably connected to the first bracket 6 via the support shaft 8; an electromagnetic heater 9 is fixedly installed at the first end of the rocker 7, and the support shaft 8 is close to the second end of the rocker 7 to increase the rotation angle of the first end of the rocker 7 when the second end of the rocker 7 is rotated; a roller seat 10, fixedly installed at the second end of the rocker 7 for supporting the rotation of a roller 11; a roller 11, rotatably connected to the roller seat 10; and a motor 12, fixedly installed on the first bracket 6 and axially... The eccentric wheel 14 is fixedly connected to the transmission shaft 13 and coaxially with the output shaft of the motor 12. The eccentric wheel 14 is fixedly connected to the transmission shaft 13 and abuts against the roller 11. The transmission shaft 13 is parallel to the axis of the roller 11. When the eccentric wheel 14 rotates around the axis of the transmission shaft 13, it can contact the roller 11. The roller 11 rolls to reduce friction. When the protruding part of the eccentric wheel 14 contacts the roller 11, it can press down the roller 11, and then press down the second end of the rocker 7, so that the first end is raised to drive the electromagnetic heater 9 to rise. The eccentric wheel 14 continues to rotate to release the pressure on the second end of the rocker 7.

[0029] like Figure 1 As shown, in some embodiments, a positioning pin 4 is inserted through the center of the round pad 3. The end of the positioning pin 4 is fastened to the turntable conveyor 2 by a fastener 5. The round pad 3 is movably mounted on the turntable conveyor 2 and can be inserted into the positioning pin 4 to prevent the round pad 3 from falling off. The fastener 5 passes through the turntable of the turntable conveyor 2 and is screwed to the end of the positioning pin 4. The positioning pin 4 can be tightened or loosened by screwing the fastener 5. The positioning pin 4 is adapted to the inner ring of the bearing to position the bearing. At the same time, different diameters can be replaced to adapt to bearings of different sizes.

[0030] In some embodiments, the drive unit and electromagnetic heater 9 are in multiple groups, which can heat multiple bearings simultaneously.

[0031] In some embodiments, the top of the air guide shroud 19 is a spherical surface, which can guide the airflow smoothly into the annular air duct between the air guide tube 18 and the air guide shroud 19.

[0032] In some embodiments, there are multiple fans 17, which can simultaneously cool multiple bearings.

[0033] In some embodiments, the circular pad 3 is made of high-temperature resistant ceramic, which can withstand the high temperature of the bearing.

[0034] In some embodiments, the drive unit further includes a limiting rod 15, which is fixedly connected to the first bracket 6 and is located above the second end of the rocker 7 to abut against the rocker 7, so that the rocker 7 can be kept in a horizontal state. When the rocker 7 is rotated to a horizontal state, the second end of the rocker 7 abuts against the limiting rod 15, and the limiting rod 15 limits the second end of the rocker 7 to prevent the first end of the rocker 7 from continuing to fall.

[0035] In some embodiments, the air guide duct 18 has a cylindrical thin-walled structure that can guide airflow along the internal space, and the air guide cover 19 has a cylindrical shape that can guide airflow into the annular air duct.

[0036] In the above structure, the bearing to be heated is placed on the round pad 3 and transported one by one to the underside of the heating tube of the electromagnetic heater 9 by the conveyor 2. When the bearing to be heated is under the heating tube, the conveyor 2 stops. At this time, the motor 12 drives the transmission shaft 13 to rotate, which drives the eccentric wheel 14 to rotate synchronously. When the protrusion of the eccentric wheel 14 moves away from the roller 11, the pressure roller 11 is released. At this time, the support shaft 8 supports the rocker plate 7 to rotate. When the roller 11 is not pressed down, the electromagnetic heater 9 at the end of the rocker plate 7 drops due to gravity. The heating tube of the electromagnetic heater 9 moves to the periphery of the bearing. Then the electromagnetic heater 9 is energized to heat the bearing. After heating is completed, the motor 12 drives the transmission shaft 13 to rotate, which drives the eccentric wheel 14 to rotate synchronously. The protrusion of the eccentric wheel 14 contacts the roller 11 and presses down the roller 11, causing the rocker plate 7 to rotate. Then, the end away from the electromagnetic heater 9 falls down, while the other end rises. At this time, the heating tube moves away from the bearing to avoid the transport of the bearing.

[0037] After the heated bearing is moved to the area below the fan 17, the fan 17 blows gas onto the bearing to accelerate its cooling. When the airflow blows onto the air guide shroud 19, the air guide shroud 19 guides the airflow to the gap between the air guide tube 18 and the air guide shroud 19, which can guide the airflow to form a ring-shaped cooling effect on the bearing, preventing the airflow from spreading before it reaches the bearing and further improving the air cooling effect.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
