Description

Technical Field

[0001] This application relates to the field of solenoid valve testing technology, and in particular to a port size testing device for solenoid valve production. Background Technology

[0002] A solenoid valve is an industrial device controlled by electromagnetic force. Essentially an automated actuator, it's a fundamental component for controlling the direction and speed of fluid flow. Its application is not limited to hydraulics and pneumatics; it's used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. After production, solenoid valves require dimensional inspection of their ports, including the inner and outer diameters and roundness. Current port dimensional inspection devices for solenoid valves use relatively primitive methods: contact sensors are used to sense the contact between the inner and outer walls of the port, calculating the difference in diameter, the inner diameter value, and the roundness. However, roundness inspection is cumbersome and inefficient. This is because it requires collecting diameter data from all locations on the inner and outer walls of the port for comparison, judging roundness through tolerances. This method generates an enormous amount of data and has low efficiency, making it unsuitable for the dimensional inspection and quality control requirements of solenoid valve ports.

Sliding columns one and two are fixedly connected to the brackets located on the left and right sides, respectively. A telescopic rod two is fixedly installed on the top of the rotating block. The telescopic end of the telescopic rod two is fixedly connected to the receiving column. Adaptor rods are fixedly connected to the front and rear sides of the top of the rotating block. The top end of the adapter rod is adapted to be inserted into the inside of the guide block.

[0006] Preferably, a tension spring is movably sleeved on the outer surface of the telescopic column, and the two ends of the tension spring are elastically connected to the bracket and the receiving column, respectively, and the tension spring is in a stretched state.

[0007] Preferably, the guide support mechanism includes two sets of connecting rods one and two rotatably mounted on the surface of the rotating block. The top ends of connecting rods one and two are rotatably connected to the bracket. The top of the rotating block is provided with an adapter groove. A support cylinder that communicates with and is adapted to the adapter groove is fixedly connected to the top of the rotating block. A support column is adapted to be inserted into the inside of the support cylinder. The top end of the support column is fixedly connected to the outer surface of the receiving column.

[0008] Preferably, the axial section of the telescopic column is "T" shaped, and the pressure sensor is fitted to the outer surface of the telescopic column in a clearance fit.

[0009] Preferably, two sets of upper and lower support columns are rotatably installed on the left and right sides of the front of the rotating block. The bottom ends of the connecting rod one and the connecting rod two are fixedly sleeved on the two ends of the support columns. The front and rear sides of the outer surface of the support columns are provided with limiting rings that abut against the rotating block.

[0010] Preferably, the second connecting rod is located above the first connecting rod, the first connecting rod and the second connecting rod are parallel to each other, and the top of the inner side of the first connecting rod and the second connecting rod are fixedly connected to a fixing column, which is adapted to be connected to the surface of the bracket.

[0011] Preferably, the front of the first connecting rod is provided with a rectangular boss, and a spring is elastically connected between the two sets of the first connecting rods through the rectangular boss.

[0014] The beneficial effects of this invention are as follows: 1. This invention completely changes the inefficient mode of traditional solenoid valve port roundness detection, which requires multiple data collection and large amounts of data comparison, by using a rotational pressure application + pressure sensing detection method. It utilizes the pressure change generated by the adapter roller's contact with the inner wall of the solenoid valve during its revolution to directly determine whether the roundness is within the tolerance range by the pressure reading difference. The detection can be completed in a single rotation, which greatly reduces the amount of data processing and significantly improves the efficiency of solenoid valve port size detection, meeting the high-efficiency requirements of batch factory quality inspection.

[0015] 2. This invention employs a parallelogram linkage guide support mechanism. Through the parallel arrangement of two connecting rods, the axis of the adapter roller is always kept vertical and stably fitted against the inner wall of the solenoid valve port. With the help of springs, adaptive opening and closing and automatic reset are achieved. The structure operates smoothly and provides reliable support, effectively reducing detection deviation. At the same time, the adapter roller dynamically fits against the inner wall as it rotates with the connecting rods, improving the accuracy and stability of roundness detection.

[0016] 3. This invention provides an independent sliding column type guide support mechanism, which uses staggered sliding columns and guide blocks to achieve horizontal sliding guidance, avoiding longitudinal displacement of the adapter rollers and significantly reducing longitudinal wear on the inner wall of the solenoid valve port; the two sets of adapter rollers move independently and do not interfere with each other, and can collect pressure data separately. The roundness can be directly determined by the difference between the maximum and minimum pressure, resulting in higher detection accuracy and smoother mechanism operation, further optimizing detection stability and service life.

[0020] The technical solutions of 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. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figures 1-9 This embodiment discloses a port size detection device for solenoid valve production, including a workbench 1, and further comprising: Motor 2 is installed on the inner bottom of workbench 1. The output shaft of motor 2 is fixedly mounted with rotating block 3. The top of rotating block 3 is mounted with receiving column 18. Two sets of pressure sensors 23 are fixedly connected to the inner wall of receiving column 18. Two sets of telescopic columns 19 are movably sleeved on the inner wall of receiving column 18. One end of telescopic column 19 is fixedly connected with bracket 6. The other end of telescopic column 19 abuts against pressure sensor 23. Adaptor roller 7 is rotatably mounted on the outer surface of bracket 6. A guide support mechanism is used to provide support and guidance for the support bracket 6 and the adapter roller 7. Telescopic rod 9 is installed on the inner top of the workbench 1. A movable frame 12 is installed at the telescopic end of the telescopic rod 9. Two sets of cylinders 13 are fixedly installed inside the movable frame 12. A clamping plate 14 is installed at the telescopic end of the cylinder 13. The solenoid valve body 8 is clamped between the two sets of clamping plates 14. As a preferred embodiment of the present invention, 1 The guide support mechanism includes two sets of connecting rods 4 and 5 rotatably mounted on the surface of the rotating block 3. The top ends of connecting rods 4 and 5 are rotatably connected to the bracket 6. The top of the rotating block 3 is provided with an adapter groove 22. The top of the rotating block 3 is fixedly connected with a support cylinder 16 that communicates with and is adapted to the adapter groove 22. A support column 17 is adapted to be inserted into the inside of the support cylinder 16. The top end of the support column 17 is fixedly connected to the outer surface of the receiving column 18. This device has been redesigned to use an adapter roller 7 that abuts against the solenoid valve body 8 to quickly detect the roundness of the port of the solenoid valve body 8. Based on the pressure reading generated by the rotation of the adapter roller 7 and the pressure reading generated by the extension column 19 pressing against the pressure sensor 23, the displacement offset of the adapter roller 7 when it abuts against the inner wall of the solenoid valve body 8 can be quickly obtained. The roundness of all positions of the inner wall of the solenoid valve body 8 can be quickly obtained. When the solenoid valve body 8 is in the standard roundness, the pressure reading of the pressure sensor 23 is K1. When the adapter roller 7 rotates with the motor 2, the rotating block 3, the first connecting rod 4 and the second connecting rod 5, it drives the extension column 19, the first connecting rod 4 and the second connecting rod 5 to move outward when it abuts against the solenoid valve body 8. The pressure reading generated by the extension column 19 pressing against the pressure sensor 23 is K2. The difference between the maximum value of all K2 values ​​and K1 is taken to determine whether it is within the roundness tolerance range. This realizes the function of quickly detecting the roundness of the port of the solenoid valve body 8, thereby significantly improving the detection efficiency of the device.

[0022] Then, the device uses the rotating block 3 and the support column 20 to rotate and support the two sets of connecting rods 1 4 and 2 5. The two sets of connecting rods 1 4 are elastically connected by the spring 15 between them, so that the two sets of connecting rods 1 4 and 2 5 are in a contracted state under the initial conditions. Then, the bracket 6 is rotatedly connected to the connecting rods 1 4 and 2 5, and the connecting rods 1 4 and 2 5 are set to be parallel, so that the axis of the bracket 6 and the adapter roller 7 is always in a vertical state. When the motor 2 drives the rotating block 3, connecting rods 1 4 and 2 5 to rotate, the centrifugal force generated can drive the two sets of connecting rods 1 4 and 2 5 to open and stretch the spring 15. At this time, the parallel arrangement of connecting rods 1 4 and 2 5 can ensure that the axis of the adapter roller 7 always remains vertical. The outer surface of the adapter roller 7 can fit and abut against the inner side of the solenoid valve body 8, thereby improving the detection accuracy of the device.

[0023] In this embodiment, the top of the rotating block 3 is provided with an adapter groove 22, and the top of the rotating block 3 is fixedly connected with a support cylinder 16 that communicates with and is adapted to the adapter groove 22. A support column 17 is adapted to be inserted into the inside of the support cylinder 16, and the top of the support column 17 is fixedly connected to the outer surface of the receiving column 18. like Figure 5 , Figure 6 As shown, the height of the receiving column 18 and the telescopic column 19 changes with the opening and closing of the two sets of connecting rods 1-4, connecting rod 2-5 and bracket 6. Therefore, the support column 17 connected to them needs to maintain sliding guidance. Therefore, an adapter groove 22 is provided on the top of the rotating block 3, and a support cylinder 16 located on the top of the rotating block 3 is provided to provide sliding support for the support column 17.

[0024] In this embodiment, the axial section of the telescopic column 19 is "T" shaped, and the pressure sensor 23 is adapted to be fitted onto the outer surface of the telescopic column 19 in a clearance fit. like Figure 4 , Figure 5 As shown, pressure sensor 23 is disposed on the inner wall of receiving column 18, and telescopic column 19 is connected to bracket 6. When rotating block 3 is driven by motor 2 to rotate, it provides connecting rod 1 4, connecting rod 2 5 and bracket 6 to drive adapter roller 7 to revolve. The adapter roller 7 and bracket 6 will drive telescopic column 19 to apply pressure to pressure sensor 23. When solenoid valve body 8 is in standard roundness, the pressure reading of pressure sensor 23 is K1. The pressure reading generated by telescopic column 19 pressing pressure sensor 23 is K2. The difference between the maximum value of all K2 and K1 is taken to determine whether it is within the roundness tolerance range. This can realize the function of quickly detecting the roundness of the port of solenoid valve body 8, thereby significantly improving the detection efficiency of the device.

[0025] In this embodiment, two sets of upper and lower support columns 20 are rotatably installed on the left and right sides of the front of the rotating block 3. The bottom ends of the connecting rod 1 4 and the connecting rod 2 5 are fixedly sleeved on both ends of the support column 20. The front and rear sides of the outer surface of the support column 20 are provided with limiting rings 21 that abut against the rotating block 3. like Figure 8 As shown, the support column 20 is used to provide rotational support for the first link 4 and the second link 5. Under the elastic tension of the spring 15, the two sets of first link 4 and second link 5 are kept in the contracted state under the initial conditions. The limiting ring 21 is used to provide a limiting function for the support column 20.

[0026] In this embodiment, the second connecting rod 5 is located above the first connecting rod 4. The first connecting rod 4 and the second connecting rod 5 are parallel to each other. The top of the inner side of the first connecting rod 4 and the second connecting rod 5 are fixedly connected to the fixing post 24. The fixing post 24 is adapted to be connected to the surface of the bracket 6. like Figure 8As shown, the upper and lower sets of support columns 20 can provide rotational support for connecting rod 1 4 and connecting rod 2 5, and achieve parallel distribution with the cooperation of bracket 6. This design can ensure that the adapter roller 7 is always in a vertical state and dynamically adapts to the inner side of the solenoid valve body 8.

[0027] In this embodiment, a rectangular boss is provided on the front of the connecting rod 4. A spring 15 is elastically connected between the two sets of connecting rods 4 through the rectangular boss. The spring 15 is stretched and set between the two sets of connecting rods 4. The surface of the rectangular boss has a rounded transition. like Figure 8 As shown, the left and right sets of connecting rods 4 are elastically connected by springs 15 and maintain a slightly elongated contracted state. The rectangular boss provides space for the springs 15.

[0028] In this embodiment, the axes of the two sets of adapter rollers 7 are always in a vertical state, and the outer surfaces of the two sets of adapter rollers 7 rotate and abut against the inner side of the solenoid valve body 8. The axis of the adapter roller 7 must always be kept vertical so that it can fit more accurately against the inner wall of the port of the solenoid valve body 8, thereby improving the detection accuracy of the device.

[0029] In this embodiment, two sets of guide cylinders 10 are fixedly connected to the top inner side of the workbench 1 in a symmetrical arrangement. Guide columns 11 are movably sleeved inside the guide cylinders 10, and the bottom of the guide columns 11 is fixedly connected to the movable frame 12. like Figure 3 , Figure 4 As shown, when the telescopic rod 9 drives the movable frame 12 to move up and down, the guide cylinder 10 and the guide column 11 can provide guidance and stability.

[0030] As a preferred embodiment of the present invention, 2 like Figure 10-12 As shown, the guide support mechanism includes a guide block 26 fixedly installed on the top of the receiving column 18. Sliding columns 27 and 28 are interleaved at the left and right ends of the outer surface of the guide block 26, respectively. Sliding columns 27 and 28 are fixedly connected to the brackets 6 located on the left and right sides, respectively. A telescopic rod 25 is fixedly installed on the top of the rotating block 3. The telescopic end of the telescopic rod 25 is fixedly connected to the receiving column 18. Adaptor rods 30 are fixedly connected to the front and rear sides of the top of the rotating block 3. The top end of the adapter rod 30 is adapted to be inserted into the inside of the guide block 26.

[0031] In this embodiment, the motor 2 drives the rotating block 3, the adapter rod 30, the receiving column 18, the telescopic column 19 and the guide block 26 to rotate. The centrifugal force generated by the motor will act on the two sets of adapter rollers 7 at the same time. The two sets of adapter rollers 7 respectively abut against the inner wall of the solenoid valve body 8, thereby independently measuring the reading of the corresponding pressure sensor 23. Finally, the difference between the highest and lowest readings of the pressure sensor 23 can be used to confirm the roundness of the solenoid valve body 8.

[0032] The guide support mechanism of this device provides sliding support for the two sets of brackets 6 and the adapter rollers 7. When the motor 2 drives the rotating block 3 and drives the adapter rod 30, guide block 26, receiving column 18, telescopic column 19, bracket 6 and adapter rollers 7 to rotate, the two sets of brackets 6 are provided with sliding support by sliding column one 27 and sliding column two 28 respectively. This reduces the friction between the telescopic column 19 and the receiving column 18 caused by the weight of the telescopic column 19, bracket 6 and adapter rollers 7, and improves the pressure accuracy of the pressure sensor 23. At the same time, sliding column one 27 and sliding column two 28 are independent of each other. Therefore, the left and right sets of adapter rollers 7 can freely adapt and abut against the inner wall of the solenoid valve body 8, so that the pressure readings obtained by the corresponding pressure sensor 23 can be independent of each other. By taking the difference between the maximum pressure and the minimum pressure received by the pressure sensor 23, it can be determined whether the roundness of the solenoid valve body 8 is compliant.

[0033] The telescopic rod 25 can drive the receiving column 18 and the guide block 26 to move upward. In order to keep the guide block 26 rotating synchronously with the rotating block 3, the adapter rod 30 enters the guide block 26 in an upward insertion posture, so as to realize the function of synchronous upward movement of the guide block 26 and synchronous rotation with the rotating block 3. Together with the two sets of connecting rods 1 4 and connecting rod 2 5, it forms another guide support mechanism. This design can avoid the adapter roller 7 moving up and down with the guide support structure. Compared with the parallelogram connecting rod structure, which needs to generate displacement in the vertical direction, the horizontally moving adapter roller 7 can reduce the longitudinal wear between itself and the inner wall of the solenoid valve body.

[0034] A tension spring 29 is movably sleeved on the outer surface of the telescopic column 19. The two ends of the tension spring 29 are elastically connected to the bracket 6 and the receiving column 18, respectively, and the tension spring 29 is in a stretched state.

[0035] like Figure 12 As shown, since the two sets of telescopic columns 19 and brackets 6 do not have synchronous limiting and resetting functions, a tension spring 29 is provided to assist in their resetting.

[0036] Working principle: When this device is in operation, it is mainly used to measure the roundness of the port of the solenoid valve body 8. Its principle is to rotate the two sets of brackets 6 and adapter rollers 7 that abut against the inner side of the solenoid valve body 8, so that their rotation axis is collinear with the axis of the solenoid valve body 8. Under the centrifugal force generated by the revolution, the adapter rollers 7 abut against the inner side of the solenoid valve body 8 and rotate to adapt, thereby driving the telescopic column 19 connected to it to move away from the support column 17, squeezing the pressure sensor 23, and recording the reading of the pressure sensor 23. If the tolerance between the reading of the pressure sensor 23 and the standard reading is within the specified range, it can be determined that the roundness of the port of the solenoid valve body 8 meets the production standard. The pressure on the pressure sensor 23 is proportional to the displacement of the telescopic column 19. Only the maximum pressure reading of the pressure sensor 23 needs to be collected to determine the maximum tolerance generated on the inner wall of the solenoid valve body 8. Then, the telescopic rod 9 is activated, causing the moving frame 12 to move upward to its highest point, locking the solenoid valve body 8 between the two sets of clamping plates 14. The two sets of cylinders 13 are then activated, respectively driving the two sets of clamping plates 14 to clamp and fix the solenoid valve body 8. Next, the telescopic rod 9 moves the moving frame 12 and the solenoid valve body 8 downward, guided by the guide cylinder 10 and guide column 11. When the solenoid valve body 8 moves to the designated height, the motor 2 is activated, driving the rotating block 3, connecting rod 4, connecting rod 5, bracket 6, and adapter roller 7 to rotate. Under centrifugal force, the adapter roller 7 moves towards the solenoid valve body. The inner wall of the solenoid valve body 8 moves, causing the two sets of connecting rods 4 and 5 to rotate and stretching the spring 15. The outer surface of the adapter roller 7 always remains in contact with the inner wall of the solenoid valve body 8. At the same time, it drives the telescopic column 19 to move. The telescopic column 19 presses the pressure sensor 23, causing the reading of the pressure sensor 23 to change according to the roundness of various points inside the solenoid valve body 8. The set with the largest difference between the reading of the pressure sensor 23 and the standard reading is selected and recorded. If the difference is within the tolerance range, the roundness of the port of the solenoid valve body 8 is qualified; otherwise, it is unqualified.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
