Description

Technical Field

[0001] This utility model relates to the field of plunger pump component testing technology, specifically a plunger pump return disc testing device. Background Technology

[0002] A piston pump is a crucial component of a hydraulic system. It relies on the reciprocating motion of a piston within a cylinder to change the volume of the sealed working chamber, thus achieving oil suction and pressure. Piston pumps offer advantages such as high rated pressure, compact structure, high efficiency, and convenient flow adjustment. However, monitoring and assessing the wear of the return disc during the return stroke requires the use of testing equipment. The return disc is a key component of the piston pump, primarily responsible for pushing it back to its original position after the piston has completed its suction, compression, and discharge operations, preparing it for the next oil intake. Severe wear of the return disc will affect the normal operation of the piston pump and may even lead to pump body damage. Therefore, regularly inspecting the wear condition of the return disc is particularly important.

[0003] Currently, there are various methods for detecting the wear of return disks, such as gravimetric analysis, manual reference methods, and optical detection methods. Among these, optical detection methods detect the wear of the return disk by examining the optical reflection characteristics of its surface. Optical detection typically uses a microscope to capture images of the return disk surface, which are then analyzed using image processing software to determine the degree of wear. However, most detection equipment uses an electric slide rail to move the microscope horizontally for scanning. Since light reflection varies at different angles, and the images captured at different angles also differ, traditional detection methods introduce errors, affecting the accuracy of return disk wear detection and resulting in relatively poor practicality.

A rotating shaft 15 is provided on one side of the slider 12, and a locking block 17 is symmetrically provided on the outer wall of one end of the rotating shaft 15. A through groove adapted to the combined structure of the locking block 17 and the rotating shaft 15 is provided on one side of the slider 12. A rotating cylinder 16 adapted to the combined structure of the rotating shaft 15 and the locking block 17 is rotatably mounted on the other side of the slider 12. A gear 18 is sleeved on the outer side of the rotating cylinder 16. A sliding groove is provided on the inner wall of one side of the adjustment seat 6, and several toothed grooves are provided on the bottom surface of the sliding groove. The gear 18 meshes with the toothed groove 2. One end of the rotating shaft 15 passes through the guide groove opened on one side wall of the adjusting seat 6. One end of the adjusting seat 6 is equipped with a motor 13 that is fixedly connected to the lead screw 10. In this example, both motor 8 and motor 13 are servo motors, and the specific models can be selected according to actual needs. The setting of the adjusting mechanism allows it to adjust the horizontal position of the scanning electron microscope 5 as needed. At the same time, it can also tilt the microscope and allow the adjusting seat 6 to rotate around the telescopic rod 4 in a circle. This allows it to adjust its position and angle as needed, enabling it to achieve multi-directional scanning imaging detection. The two mechanisms complement each other, thereby improving the detection accuracy, detection effect, and practicality.In this example, the fixing component includes a fixing block 19, which is sleeved on the outer side of one end of the rotating shaft 15. The top of the fixing block 19 is provided with a pin 20 that passes through the fixing block 19. The lower outer side of the pin 20 is movably sleeved with a torsion cylinder 21 at the bottom of the fixing block 19. A fixing seat 22 is sleeved on the outer side of the torsion cylinder 21, and the fixing seat 22 is fixedly connected to the fixing block 19. A collar 23 and a torsion spring 24 are sleeved on the outer side of the torsion cylinder 21 inside the fixing seat 22, and the collar 23 is rotatably connected to the fixing seat 22. The two ends of the torsion spring 24 are fixedly connected to the fixing seat 22 and the collar 23, respectively. A limiting block 25 is symmetrically provided on the upper inner wall of the torsion cylinder 21. A rail groove 26 adapted to the limiting block 25 is symmetrically opened on the outer wall of the pin 20. The setting of the fixing component can facilitate the disassembly and assembly of the mounting bracket 14 and the scanning electron microscope 5, so as to periodically disassemble, maintain, repair or replace the scanning electron microscope 5.

[0022] In this example, the mounting bracket 14 is L-shaped, the rotating shaft 15 is located between the lead screw 10 and the guide rod 11, and the rotating cylinder 16 is rotatably connected to the slider 12 via a bearing, so as to support and fix the scanning electron microscope 5 through the mounting bracket 14. In this example, several rolling balls are movably embedded in the side wall of the fixing block 19 near the adjusting seat 6, and the rolling balls are arranged in a circumferentially equidistant array to reduce the friction between the fixing block 19 and the adjusting seat 6, making it easier to move. In this example, the collar 23 is fixedly connected to the torsion cylinder 21, the rail groove 26 is L-shaped, and the two rail grooves 26 are arranged in a circumferentially equidistant array to guide and limit the limiting block 25, thereby realizing the restriction and fixation of the pin shaft 20.

[0023] The working principle of this utility model is as follows: In use, the scanning electron microscope 5 is moved horizontally by the electric slide rail 3 to scan and inspect the surface of the return disk below. Then, the motor 13 drives the lead screw 10 to rotate in both directions, causing the lead screw 10 to drive the slider 12 to move. At the same time, the slider 12 drives the rotating shaft 15, the mounting bracket 14, and the scanning electron microscope 5 to move synchronously. Simultaneously, the slider 12 also drives the gear 18 to move. The gear 18 meshes with the tooth groove, causing the gear 18 to drive the rotating cylinder 16 to rotate. This, in turn, drives the rotating shaft 15 through the locking block 17, causing the mounting bracket 14 to rotate synchronously, thereby changing the tilt angle of the scanning electron microscope 5. Then, scanning and inspection can be performed again. Afterwards, the motor 8 drives the gear 9 to rotate, which meshes with the tooth groove on the outer wall of the connecting sleeve 7. This drives the adjusting seat 6 to rotate around the telescopic end of the telescopic rod 4, thereby changing its horizontal circumferential angle. After scanning and detection, multiple sets of detection data are integrated and analyzed to improve the accuracy of the data and the detection effect. When the scanning electron microscope 5 needs to be disassembled for maintenance, the torsion cylinder 21 can be twisted to drive the limiting block 25 and the collar 23 to rotate, causing the collar 23 to twist the torsion spring 24. At the same time, the torsion cylinder 21 drives the limiting block 25 to move in the rail groove 26. After the limiting block 25 aligns with the opening of the rail groove 26, the pin 20 can be pulled out. Then the mounting bracket 14 can be pulled to pull out the rotating shaft 15 from the rotating cylinder 16 and the slider 12, completing the disassembly of the mounting bracket 14 and the scanning electron microscope 5 for maintenance. This method is convenient to use and more practical.
