Description

Technical Field

[0001] This utility model relates to the field of testing, and in particular to a universal cylinder airtightness testing device. Background Technology

[0002] Cylinders are commonly used power components in mechanical equipment. They convert the pressure energy generated by compressed air into mechanical energy, thereby driving the mechanism to achieve reciprocating linear motion, oscillating motion, or rotary motion. Cylinders have a wide range of applications, including automation control, industrial machinery manufacturing, metallurgical industry, and other fields. Therefore, the airtightness of cylinders is of paramount importance.

[0003] For example, Chinese Utility Model Application No. CN202320939919.1 discloses a cylinder airtightness testing device, relating to the field of testing devices. The device includes a main body and a chassis. A slide rail is provided on the chassis, and a tray is slidably connected to the slide rail. Bases are fixedly installed on both sides of the tray, and a fixing plate is fixedly installed on the base. A clamping mechanism is provided on the fixing plate, comprising a movable plate, a gear, a support plate, and a clamping head. The fixed plate has a movable plate, and a gear is rotatably mounted on the fixing plate. The support plate is connected to the gear via a rotating shaft, and a clamping head is fixedly installed at the end of the support plate. This utility model, by setting up a clamping mechanism, ensures that the testing device can firmly fix the cylinder during testing, preventing the cylinder from shaking due to the pressure generated by gas ejection, or preventing minor vibrations during operation that could cause the cylinder to not be fixed in its original position, leading to gas leakage and affecting the test results.

[0004] However, the above technical solutions still have the following technical problems in practical use:

[0005] The aforementioned clamping mechanism, with its gears and shafts, causes vibrations in the cylinder during airtightness testing. This vibration causes the cylinder to vibrate, which in turn forces the clamping head, leading to gear slippage and displacement of the clamping head. Consequently, the cylinder is not fixed in its original position. Furthermore, the clamping head's retraction range is limited by the gears, making it ineffective at securing cylinders of varying sizes. This results in gas leakage during testing, affecting the test results. Utility Model Content

[0006] The present invention aims to provide a cylinder airtightness testing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A universal cylinder airtightness testing device includes a base, a placement plate connected to the base, a support connected to the base, a worm gear connected to the support, a fixed plate connected to the support, the fixed plate connected to the base, a threaded rod rotatably connected to the fixed plate, a worm wheel connected to the threaded rod, the worm gear meshing with the worm wheel, a turntable connected to the worm gear, a handle connected to the turntable, a support plate threadedly connected to the threaded rod, a first slider connected to the support plate, a first slide groove provided on the base, the first slider slidably connected to the first slide groove, a rotating block connected to the support plate, a bidirectional threaded rod connected to the rotating block, and a... The second slider has a second groove on the support plate, and the second slider is slidably connected to the second groove. The second slider is connected to a clamping plate, the base is connected to a connecting column, the connecting column is connected to a top plate, the top plate is connected to an air pump, the top plate is connected to a control panel, the control panel is connected to a display screen, the control panel is connected to a switch, the top plate is connected to an electric push rod, the switch is electrically connected to the electric push rod, the electric push rod is connected to a pressure plate, the pressure plate is connected to a detection device, the air pump is connected to an air inlet pipe, the air inlet pipe is connected to the detection device, the detection device is connected to an air outlet pipe, and the detection device is electrically connected to the control panel.

[0009] Preferably, the base is connected to a fixing post.

[0010] Preferably, the fixed pile is connected with a shock-absorbing sleeve.

[0011] Preferably, the base is provided with a placement slot.

[0012] Preferably, the pressure plate is connected with a rubber pad.

[0013] Preferably, the clamping plate is connected with a cushioning pad.

[0014] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0015] (1) By setting up a clamping plate, a support plate, a threaded rod, a placement plate, a placement groove and an electric push rod, the cylinder placed in the placement groove can be firmly fixed on the placement plate. Since the clamping plate can be moved, the size of the clamping plate can be adjusted to better fit cylinders of different sizes, thereby achieving the clamping effect on cylinders of different sizes. Furthermore, when this device is used to test air tightness, the clamping plate will not move due to the vibration generated by the device because of the threaded rod, thus enabling the air tightness testing device to accurately test the air tightness of the cylinder.

[0016] (2) By setting a worm gear, when the handle is turned, the worm can drive the worm wheel to rotate, and the worm wheel can drive the threaded rod to rotate. Since there are two symmetrically arranged worm gears, the support plate can be more stable under the self-locking feature of the worm gear, thus making the clamping plate more stable.

[0017] (3) By setting fixed piles and shock-absorbing sleeves, the vibration generated by the entire device during testing can be reduced.

[0018] (4) By setting a rubber pad on the pressure plate, the pressure plate can be firmly pressed on the upper part of the cylinder, making the cylinder more stable during testing. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figure 1-3The universal cylinder air tightness testing device 9 shown includes a base 1. A placement plate 11 is connected to the upper right side of the base 1. Fixing posts 21 are connected to the lower perimeter of the base 1. A shock-absorbing sleeve 20 is connected to the outside of the fixing posts 21 to provide shock absorption and fixation for the device. A fixing block 32 is connected to the upper end of the base 1. Supports 3 are symmetrically arranged on the right side of the fixing plate. A worm gear 22 is rotatably connected to the support 3. A threaded rod 19 is symmetrically arranged on the right side of the fixing block 32. The threaded rod 19 is connected to a worm wheel 23. The worm wheels 23 are symmetrically arranged below the worm gear 22. The worm gear 22 and the worm wheel 23 are connected to each other. The worm gear 22 is connected to a turntable 13 at its front end, and a handle 14 is connected to the turntable 13. A threaded rod 19 is threadedly connected to a support plate 15, which is positioned between the support 3 and the placement plate 11. A first slider 31 is connected to the lower part of the support plate 15, and a first groove 17 is provided above the base 1. The first slider 31 is slidably connected to the first groove 17. When the handle 14 is turned, the worm gear 22 rotates, which drives the worm wheel 23 to rotate, and the worm wheel 23 drives the threaded rod 19 to rotate. Due to the arrangement of the first groove 17 and the first slider 31, the placement plate 11 moves along the groove. A clamping plate 18 is connected to the right wall of the support plate 15. Two sets of clamping plates 18 are provided, each being an arc-shaped plate. The two sets of clamping plates 18 are symmetrically arranged. A second sliding groove 29 is formed on the right wall of the support plate 15. A second slider 30 is connected to one end of the clamping plate 18 near the support plate 15. The second slider 30 is slidably connected to the second sliding groove 29. A bidirectional threaded rod 2819 is rotatably connected to the support plate 15. The bidirectional threaded rod 2819 passes through the second sliding groove 29, and symmetrical positive threads are arranged on the bidirectional threaded rod 2819 with the center of the second sliding groove 29 as the midpoint. The base 1 has a threaded rod 2819 with both horizontal and vertical threads. The double-threaded rod 2819 is threadedly connected to two sets of second sliders 30. The double-threaded rod 2819 is rotatably connected to the support plate 15. The two sets of second sliders 30 are symmetrically arranged. A rotating block 16 is connected to the double-threaded rod 2819. The rotating block 16 is located at the front end of the support plate 15. A buffer pad 33 is connected to the front end of the clamping plate 18. When the rotating block 16 is rotated, it drives the two sets of second sliders 30 to move in opposite directions along the second slide groove 29, thereby controlling the clamping range of the clamping plate 18 to accommodate cylinders of different sizes. A placement groove 12 is provided at the upper end of the base 1, located between the placement plate 11 and the support plate 15, allowing the clamping plate 18 to firmly clamp the cylinder onto the placement plate 11.

[0025] like Figure 1-3The diagram shows a universal cylinder airtightness testing device 9. A base 1 has connecting columns 2 around its upper perimeter, which together connect to a top plate 4. An air pump 5 is connected to the top of the top plate 4, and a control panel 6 is also connected to it. A switch 8 is connected to the control panel 6. An electric push rod 24 is connected to the lower end of the top plate 4, and a pressure plate 10 is connected to it. The pressure plate 10 is located above a placement slot 12. The electric push rod 24 is electrically connected to the switch 8. A testing device 9 is connected above the pressure plate 10. The air pump 5 is connected to an air inlet pipe 27, the other end of which is connected to the testing device 9. The testing device 9 is connected to an air outlet pipe 26. The control panel 6 is electrically connected to the testing device 9. Activating the switch 8 controls the retraction of the electric push rod 24, allowing the pressure plate 10 to press against the cylinder. A rubber pad 25 is provided below the pressure plate 10 to ensure a tight seal between the pressure plate 10 and the cylinder, preventing inaccurate testing due to poor sealing.

[0026] The specific implementation process is as follows:

[0027] The cylinder to be tested is placed in the placement slot 12. The handle 14 is turned, causing the worm gear 22 to rotate. The worm gear 22 then rotates the worm wheel 23, which in turn rotates the threaded rod 19. The threaded rod 19 is threadedly connected to a support plate 15, which is connected to a first slider 31. The base 1 has a first sliding groove 17, and the first slider 31 is slidably connected to the first sliding groove 17. Therefore, when the threaded rod 19 rotates, the support plate 15 moves along the first sliding groove 17. When the clamping plate 18 contacts the cylinder, the rotating block 16 is rotated, causing... The clamping range of the clamping plate 18 is expanded or reduced so that the clamping plate 18 can fit with the cylinder, making the clamping effect better. Then, the handle 14 is turned so that it is close to the cylinder. After the cylinder is clamped on the placement plate 11, the switch 8 on the control panel 6 is turned on so that the electric push rod 24 extends downward and the pressure plate 10 with rubber pad 25 presses the cylinder. Then, the air pump 5 is turned on to introduce air into the detection device 9. The detection device 9 then inflates the cylinder through the air outlet pipe 26. The air tightness of the cylinder can be determined by the pressure on the display screen 7.
