Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a dual-station testing device for testing PRP separator chambers. Background Technology

[0002] Currently, PRP separators on the market are available in two sizes: 30ml and 60ml. To ensure the accuracy of the test, the PRP separator needs to have a high degree of sealing. The sealing performance of the PRP separator is mainly determined by the PRP separator chamber. Therefore, during the production of PRP separators, it is necessary to conduct an airtightness test on the PRP separator chamber. Furthermore, after the airtightness test, it is also necessary to check whether the two internal drainage holes on the inner cavity of the PRP separator chamber are up to standard. Currently, most airtightness testing equipment for PRP separator chambers on the market can perform airtightness testing well. However, since there are two specifications of PRP separator chambers, it is necessary to change the corresponding fixtures when testing the two specifications of PRP separator chambers separately. The fixture change is cumbersome, and traditional fixtures cannot test the inner drainage holes of the inner cavity. It is necessary for the staff to place it on a separate testing table for testing. However, the inner cavity of the PRP separator chamber is conical, which is not only inconvenient to fix, but also prone to inaccurate testing due to the small diameter of the inner drainage holes. Utility Model Content

[0003] The purpose of this invention is to provide a dual-station testing device for PRP separator chamber testing. It can perform dual-station testing of PRP separator chambers of the same specification by setting positioning sleeves of the same size in two testing fixtures, and can also set positioning sleeves of different sizes in two testing fixtures to achieve simultaneous testing of two PRP separator chambers of different specifications. Furthermore, it can accurately verify whether the internal exhaust hole is qualified through exhaust test.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a dual-station testing device for PRP separator chamber testing, comprising: a frame, a platform horizontally placed on the frame, two leak detectors and a touch screen central control screen mounted on the frame, the touch screen central control screen being electrically connected to the two leak detectors, a gas source processor connected to a gas source being mounted in the frame, two air pipes being mounted on the outlet end of the gas source processor, the two air pipes being respectively connected to the inlet ends of the two leak detectors, and two testing fixtures being mounted on the platform, each fixture comprising: a positioning sleeve, a servo slide, and a buffer cylinder, with mounting holes provided on the platform, the positioning sleeve passing through... Bolts are fixed in the mounting holes. The servo slide is vertically mounted on the upper wall of the platform and electrically connected to the touch screen control panel. A sealing plate is set on the slide plate of the servo slide. An air passage is set in the sealing plate. One end of the air passage is connected to the air outlet of the airtight leak detector, and the other end of the air passage is connected to the air return of the airtight leak detector. An air nozzle connected to the air passage is sealed on the lower wall of the sealing plate. The air nozzle is coaxially aligned with the positioning sleeve. A buffer cylinder is vertically mounted on the lower wall of the platform. A solenoid valve is set between the air source and the buffer cylinder. The solenoid valve is electrically connected to the touch screen control panel. A positioning block is movably set above the piston rod of the buffer cylinder.

[0005] Furthermore, in the aforementioned dual-station testing equipment for PRP separator chamber testing, the positioning sleeve in the testing fixture has two specifications: one is that the large-diameter end in the stepped through hole is adapted to the valve cover of the PRP separator chamber with a volume of 30ml, and the other is that the large-diameter end in the stepped through hole is adapted to the valve cover of the PRP separator chamber with a volume of 60ml.

[0006] Furthermore, the aforementioned dual-station testing equipment for PRP separator chamber testing includes a dustproof plate and a protective plate on the platform. The protective plate is fixedly connected to the frame, while the dustproof plate is detachably connected to the frame. Two elongated holes are vertically arranged at both ends of the dustproof plate, with the smaller diameter end of the elongated hole at the top and the larger diameter end at the bottom. Bolts are threaded through the elongated holes and connected to the frame. LED supplementary lights are installed on the frame located inside the dustproof plate and the protective plate.

[0007] Furthermore, the aforementioned dual-station testing equipment for PRP separator chamber testing includes a main alarm light on the top of the frame and a sub-alarm light next to each testing fixture. The two sub-alarm lights are not only electrically connected to the touch control screen, but also electrically connected to the servo slide, the solenoid valve on the buffer cylinder, and the air tightness leak detector on their respective testing fixtures. The main alarm light is electrically connected to the two sub-alarm lights through the touch control screen.

[0008] Furthermore, in the aforementioned dual-station testing equipment for PRP separator chamber testing, a sensing plate is provided on the side wall of the slide plate, and an upper limit switch and a lower limit switch are provided on the servo slide plate on the same side as the sensing plate. Both the upper limit switch and the lower limit switch are electrically connected to the touch control screen.

[0009] Furthermore, in the aforementioned dual-station testing equipment for PRP separator chamber testing, the specific connection structure between the buffer cylinder and the platform is as follows: two fixed seats are provided on the lower end wall of the platform, a cylinder seat is provided between the two fixed seats, the buffer cylinder is fixed on the cylinder seat, guide rods are slidably provided in the cylinder seats located on both sides of the buffer cylinder, an mounting plate is provided between the two guide rods, the mounting plate is connected to the piston rod of the buffer cylinder through a floating joint, and a positioning block is fixed on the mounting plate.

[0010] Furthermore, in the aforementioned dual-station testing equipment for PRP separator chamber testing, three limiting blocks are evenly distributed around the upper wall of the positioning block, and a limiting slot is left between the three limiting blocks.

[0011] The advantages of this invention are as follows: dual-station testing of PRP separator chambers of the same specification can be performed by setting positioning sleeves of the same size in two testing fixtures; and synchronous testing of two PRP separator chambers of different specifications can be achieved by setting positioning sleeves of different sizes in two testing fixtures. Moreover, the positioning sleeves are connected to the platform by bolts, making replacement convenient. The vertical displacement distance of the inner cavity of the PRP separator chamber can be precisely controlled by a servo motor, so that the two inner exhaust holes on the inner cavity can be aligned with the outer exhaust holes on the valve cover. The gas in the inner cavity will not be blocked when it is discharged outward. In this way, the touch screen can compare the detected exhaust time with the preset qualified exhaust time of the inner exhaust hole to determine whether the inner exhaust hole is qualified.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0019] like Figures 1-6 As shown, the dual-station testing equipment for PRP separator chamber testing according to this utility model includes: a frame 1, a platform 11 horizontally placed on the frame 1, two airtightness leak detectors 12 and a touch screen control panel 13 mounted on the frame 1, both the airtightness leak detectors 12 and the touch screen control panel 13 being existing technologies, the touch screen control panel 13 being electrically connected to the two airtightness leak detectors 12, and an air source processor 14 connected to an air source being installed in the frame 1, with two [unclear text - possibly related to air source processors] mounted on the air outlet end of the air source processor 14. Two air tubes (not shown in the figure) are connected to the air inlets of two airtightness leak detectors 12, respectively. A dustproof plate 15 and a protective plate 16, connected to the frame 1, are installed on the platform 11. The protective plate 16 is fixedly connected to the frame 1, while the dustproof plate 15 is detachably connected to the frame 1. Two elongated holes 151 are vertically arranged at both ends of the dustproof plate 15, with the smaller diameter end of the holes 151 at the top and the larger diameter end at the bottom. Bolts 1 are inserted through the elongated holes 151. 52. Bolt 152 is threaded onto the frame 1. An LED supplementary light 17 is installed on the frame 1 located within the dustproof plate 15 and the protective plate 16. Two testing fixtures 2 are installed on the platform 11. A main alarm light 18 is installed on the top of the frame 1. A sub-alarm light 19 is installed next to each testing fixture 2. The two sub-alarm lights 19 are not only electrically connected to the touch control screen 13, but also electrically connected to the testing fixture 2 and the airtight leak detector 12 on their respective sides. The main alarm light 18 is electrically connected to the two sub-alarm lights 19 through the touch control screen 13. When a testing fixture 2 malfunctions, the corresponding sub-alarm light 19 and the main alarm light 18 will light up. The staff can know that the entire equipment has malfunctioned by observing the main alarm light 18. During maintenance, the sub-alarm lights 19 can be used to quickly determine which testing fixture 2 has malfunctioned. Finally, the specific malfunction of the testing fixture 2 can be found through the touch control screen 13. When using the inspection fixture 2 for inspection work, the dust cover 15 needs to be removed first, and then the LED supplement light 17 needs to be turned on to increase the brightness of the inspection area. When not performing inspection work, the LED supplement light 17 needs to be turned off and the dust cover 15 needs to be reinstalled for dust prevention.

[0020] The testing fixture 2 includes a positioning sleeve 21, a servo slide 22, and a buffer cylinder 23. Mounting holes are provided on the platform 11, and the positioning sleeve 21 is fixed in the mounting holes by bolts. A stepped through-hole 211 is provided in the positioning sleeve 21. The positioning sleeve 21 comes in two specifications: one specification has a large-diameter end in the stepped through-hole 211 that matches the valve cover 31 of a 30ml PRP separator chamber 3; the other specification has a large-diameter end in the stepped through-hole 211 that matches the valve cover 31 of a 60ml PRP separator chamber 3. The servo slide 22 is vertically mounted on the upper end of the platform 11. The servo slide 22 is electrically connected to the touch screen 13 and the corresponding alarm lights 19. A sensor 222 is installed on the side wall of the slide plate 221 of the servo slide 22. An upper limit switch 223 and a lower limit switch 224, located on the same side as the sensor 222, are installed on the servo slide 22. Both the upper limit switch 223 and the lower limit switch 224 are electrically connected to the touch screen 13. When the upper limit switch 223 or the lower limit switch 224 senses the sensor 222 on the slide plate 221, the touch screen 13 can control the servo slide 22 to stop moving, preventing the slide plate 221 from moving up or down. Excessive displacement can cause danger. A sealing plate 225 is provided on the slide plate 221 of the servo slide 22. An air passage 226 is provided within the sealing plate 225. One end of the air passage 226 is connected to the air outlet of the airtight leak detector 12, and the other end is connected to the air return of the airtight leak detector 12. An air nozzle 24, communicating with the air passage 226, is sealed on the lower end wall of the sealing plate 225. The air nozzle 24 is coaxially aligned with the positioning sleeve 21. Two fixed seats 231 are provided on the lower end wall of the platform 11, and a cylinder seat 232 is provided between the two fixed seats 231. The air cylinder 23 is fixed on the cylinder seat 232. A solenoid valve (not shown in the figure) is provided between the buffer cylinder 23 and the air source. The solenoid valve is electrically connected to the touch screen 13. Guide rods 233 are slidably arranged in the cylinder seats 232 located on both sides of the buffer cylinder 23. An mounting plate 234 is provided between the two guide rods 233. The mounting plate 234 is connected to the piston rod of the buffer cylinder 23 through a floating joint 235. A positioning block 236 is provided on the mounting plate 234. Three limit blocks are evenly distributed around the upper wall of the positioning block 236. A limit slot is left between the three limit blocks.

[0021] The PRP separator chamber 3 includes a valve cover 31, a piston shaft 32, an inner cavity 33, and a spring 34. The inner cavity 33 is slidably sealed within the valve cover 31. An external discharge hole is provided on the side wall of the valve cover 31, and two internal discharge holes of different sizes are provided vertically on the side wall of the inner cavity 33. The external discharge hole and the internal discharge hole are located on the same side. The piston shaft 32 is connected to the inner cavity 33, and the spring 34 is fitted onto the piston shaft 32 and abuts against the valve cover 31. When the spring 34 in the PRP separator chamber 3 is in an uncompressed state, the lower internal discharge hole is opposite to the external discharge hole on the valve cover 31. When the PRP separator chamber 3 is connected to the outer shell to form a PRP separator, the piston shaft 32 is pushed, thereby compressing the spring 34. At this time, the external discharge hole on the valve cover 31 is offset from the two internal discharge holes on the inner cavity 33, keeping the PRP separator chamber 3 sealed.

[0022] When it is necessary to inspect the PRP separator chamber 3, first replace the corresponding positioning sleeve 21 according to the specifications of the PRP separator chamber 3 to be inspected. Since there are two inspection fixtures 2, when only one specification of PRP separator chamber 3 is produced, the same specification of positioning sleeve 21 can be installed in the two inspection fixtures 2, which can speed up the inspection efficiency. If two specifications of PRP separator chamber 3 are produced at the same time, two different specifications of positioning sleeve 21 need to be installed in the two inspection fixtures 2, so that the two specifications of PRP separator chamber 3 can be inspected. When the PRP separator chamber 3 is fixed in the positioning sleeve 21, the valve cover 31 on the PRP separator chamber 3 abuts against the stepped hole 211 of the positioning sleeve 21. The buffer cylinder 23 drives the positioning block 236 to move upward, so that the three limit blocks of the positioning block 236 are inserted into the piston shaft 32 on the PRP separator chamber 3. Then, the servo slide 22 is activated, and the servo slide 22 drives the air nozzle 24 to move downward until the air nozzle 24 extends into the PRP separator chamber 3 and seals the PRP separator chamber 3. When the air nozzle 24 blocks the PRP separator chamber 3 downwards, it exerts downward pressure on the PRP separator chamber 3, forcing the inner cavity 33 to move downwards. The air nozzle 24 experiences a significant impact force upon contact with the PRP separator chamber 3, which is cushioned by the buffer cylinder 23. The buffer cylinder 23 then drives the positioning block 236 to move downwards, disengaging from the piston shaft 32. The servo slide 22 then drives the air nozzle 24 to continue pressing down, causing the inner cavity 33 within the PRP separator chamber 3 to move downwards, causing the two inner... The exhaust port is offset from the external exhaust port of the valve cover 31. At this time, the inner cavity 33 of the PRP separator chamber 3 is in a sealed state. Then, the air tightness tester 12 is controlled to operate via the touch screen 13. The air source enters the air tightness tester 12 after being filtered by the air source processor 14, and then enters the air passage 226 of the sealing plate 225 from the air tightness tester 12. Part of the gas in the air passage 226 returns to the air tightness tester 12 and is not discharged outward, while the other part of the gas fills the PRP separator chamber 3. Based on the principle of communicating vessels, the pressure value displayed on the airtight leak detector 12 is the pressure value in the PRP separator chamber 3. When the pressure value in the PRP separator chamber 3 reaches the detection value, inflation is stopped and the chamber is left to stand for a period of time. If the pressure value on the airtight leak detector 12 does not change, it means that the sealing of the PRP separator chamber 3 is qualified. If the pressure value on the airtight leak detector 12 drops, it means that the sealing of the PRP separator chamber 3 is unqualified, and the corresponding alarm light 19 will flash to indicate that it is unqualified.

[0023] After the airtightness test of the PRP separator chamber 3 is passed, it is necessary to test whether the two internal exhaust holes of the PRP separator chamber 3 are qualified. The qualification of the internal exhaust holes is tested by the exhaust method. First, the exhaust time S1 and S2 of the two qualified internal exhaust holes under a specific air pressure are set in the touch control screen 13. The specific air pressure refers to the air pressure value used when testing the airtightness.

[0024] First, the diameter of the inner discharge hole located at the top in the inner cavity 33 is detected. At this time, the servo motor 22 drives the air nozzle 24 to continue to push the inner cavity 33 of the PRP separator chamber 3 downward. After the inner cavity 33 overcomes the spring 34 on the piston shaft 32, it moves downward so that the inner discharge hole located at the top in the inner cavity 33 is aligned with the outer discharge hole of the valve cover 31. The gas in the inner cavity 33 will be discharged outward from the aligned inner and outer discharge holes. The air release time S1' of the PRP separator chamber 3 can be detected by touching the central control screen 13 in conjunction with the air tightness tester 12. If S1'=S1, it means that the inner discharge hole is qualified. If S1'≠S1, it means that the inner discharge hole is unqualified. The alarm light 19 will flash to indicate that it is unqualified.

[0025] After measuring the inner discharge hole located at the top, the servo motor 22 drives the air nozzle 24 to reset upwards. The inner cavity 33 of the PRP separator chamber 3 resets synchronously under the elastic force of the spring 34, causing the outer discharge hole on the valve cover 31 to misalign with the two inner discharge holes of the inner cavity 33. Then, the inner cavity 33 is filled with gas and maintained at the set pressure. The servo motor 22 drives the air nozzle 24 to move upwards, and the inner cavity 33 resets upwards under the elastic force of the spring 34. During the reset process, the air nozzle 24 remains sealed on the inner cavity 33. 33 As the air nozzle 24 continues to return upward until the spring 34 is no longer compressed, the inner discharge hole located below aligns with the outer discharge hole on the valve cover 31. The gas in the inner cavity 33 will be discharged outward from the aligned inner and outer discharge holes. The central control screen 13, in conjunction with the air tightness tester 12, can detect the exhaust time S2' of the PRP separator chamber 3. If S2'=S2, it means that the inner discharge hole is qualified. If S2'≠S2, it means that the inner discharge hole is unqualified, and the alarm light 19 will flash to indicate that it is unqualified.
