Description

Technical Field

[0001] This application relates to the technical field of equipment airtightness testing, and more specifically, to a device for testing the airtightness of a shock absorber tube. Background Technology

[0002] Vibration damping tubes are flexible shock-absorbing components used to reduce the impact of vibration on equipment. They are installed in semiconductor temperature control equipment in the semiconductor industry, and are welded to copper tubing. Semiconductor temperature control equipment has high requirements for airtightness; therefore, the airtightness of the vibration damping tubes must be tested before installation.

[0003] The inventors of this application discovered that current methods for testing the airtightness of vibration dampers before they leave the factory mainly rely on sampling. Vibration dampers are easily damaged by compression and impacts during storage and transportation. Before installing the vibration dampers into semiconductor temperature control equipment, the existing testing method involves visually inspecting the dampers to determine if they are damaged, thus assessing their airtightness. This inspection method suffers from poor reliability, low testing efficiency, and high labor costs.

[0032] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] According to one aspect of this application, a device for detecting the airtightness of a shock absorber tube is provided. Figure 1 A schematic diagram of the structure of the shock absorber air tightness testing device according to an embodiment of this application is shown.

[0034] According to the example embodiment, such as Figure 1 As shown, the shock absorber airtightness testing device 1 includes a base 11, a first fixing component 12, and a second fixing component 13. The first fixing component 12 includes a first guide rail 121, a first fixing member 122, and a first driving member 123. The first guide rail 121 is disposed at one end of the base 11. The first fixing member 122 is slidably disposed on the first guide rail 121 and connected to an external air pressure regulating device (not shown in the figure). The first fixing member 122 inputs first gas from the external air pressure regulating device into the shock absorber to be tested (not shown in the figure). The first driving member 123 is disposed on the base 11 and connected to the first fixing member 122, driving the first fixing member 122 to slide on the first guide rail 121 until the first fixing member 122 seals and fixes one end of the shock absorber to be tested.

[0035] For example, the base 11 can be a rectangular plate-shaped metal structure. The first driving member 123 can be a displacement adjustment device with a telescopic mechanism. Exemplarily, the first driving member 123 can be a cylinder or an electric cylinder. For example, the connection method between the first guide rail 121 and the first driving member 123 and the base 11 can be a detachable connection or a fixed connection. Exemplarily, the detachable connection can be a threaded connection, and the fixed connection can be welding. For example, the first gas is gas input to one end of the shock absorber tube under test by an external air pressure regulating device.

[0036] The second fixing component 13 includes a second guide rail 131, a second fixing member 132, and a second driving member 133. The second guide rail 131 is disposed opposite to the first guide rail 121 at the other end of the base 11. The second fixing member 132 is slidably disposed on the second guide rail 131 and connected to an external air pressure regulating device. The second fixing member 132 inputs a second gas from the external air pressure regulating device into the shock absorber tube under test. The second driving member 133 is disposed on the base 11 and connected to the second fixing member 132, driving the second fixing member 132 to slide on the second guide rail 131 until the second fixing member 132 seals and fixes the other end of the shock absorber tube under test. The external air pressure regulating device detects the airtightness of the shock absorber tube under test based on the pressure data of the first gas and / or the second gas.

[0037] For example, the external air pressure regulating device can be a pressure-holding device with an air pressure detection mechanism. The external air pressure regulating device can detect changes in air pressure inside the shock absorber tube under test, thereby confirming the airtightness of the tube. For example, the second gas is the gas input from the external air pressure regulating device to the other end of the shock absorber tube under test.

[0038] For example, the second drive member 133 can be a displacement adjustment device with a telescopic mechanism. Exemplarily, the second drive member 133 can be a cylinder or an electric cylinder. For example, the connection method between the second guide rail 131 and the second drive member 133 and the base 11 can be either a detachable connection or a fixed connection. Exemplarily, the detachable connection can be a threaded connection, and the fixed connection can be welding.

[0039] Through the above embodiments, this application, by setting a first driving component and a second driving component, enables the fixing component to slide on the guide rail and seal and fix both ends of the shock absorber tube. This process eliminates the need for manual adjustment, simplifies the manual clamping process before testing, thereby shortening the testing time and improving testing efficiency. Furthermore, the fixing component of this application uses an external air pressure regulating device to input gas, combined with precise positioning guided by the guide rail, to ensure the sealing of the shock absorber tube, reducing the risk of gas leakage and thus improving the accuracy and reliability of the airtightness test of the shock absorber tube under test. Moreover, this application reduces reliance on manpower, thereby saving labor costs.

[0040] Figure 2A schematic diagram of the structure of the first and second fasteners of this application is shown. According to some embodiments of this application, such as... Figure 1 and Figure 2 As shown, the first fixing member 122 includes a first base plate 1221, a first vertical plate 1222, and a first sealing member 1223. The first base plate 1221 is slidably mounted on the first guide rail 121. The first vertical plate 1222 is connected to the first base plate 1221. The first sealing member 1223 is disposed on the first vertical plate 1222, with one end connected to an external air pressure regulating device and the other end sealing and fixing one end of the shock absorber tube to be tested. The second fixing member 132 includes a second base plate 1321, a second vertical plate 1322, and a second sealing member 1323. The second base plate 1321 is slidably mounted on the second guide rail 131. The second vertical plate 1322 is connected to the second base plate 1321. The second sealing member 1323 is disposed on the second vertical plate 1322, with one end connected to an external air pressure regulating device and the other end sealing and fixing the other end of the shock absorber tube to be tested.

[0041] For example, both the first base plate 1221 and the second base plate 1321 are metal plates. The first vertical plate 1222 can be perpendicularly connected to the first base plate 1221, and the first base plate 1221 and the first vertical plate 1222 form an L-shaped support structure. The second vertical plate 1322 can be perpendicularly connected to the second base plate 1321, and the second base plate 1321 and the second vertical plate 1322 form an L-shaped support structure.

[0042] Through the above embodiments, this application improves the coaxiality of the seal and the pipe end of the shock absorber tube under test by using guide rails for guiding and rigid support of the base plate and vertical plate, thereby improving the accuracy of positioning and sealing.

[0043] According to some embodiments of this application, such as Figure 2 As shown, the first fixing member 122 further includes a first buffer member 1224. The first buffer member 1224 includes a first connecting member 12241 and a first elastic member 12242. One end of the first connecting member 12241 is connected to the first driving member 123. One end of the first elastic member 12242 is connected to the first vertical plate 1222, and the other end is connected to the other end of the first connecting member 12241. The second fixing member 132 further includes a second buffer member 1324. The second buffer member 1324 includes a second connecting member 13241 and a second elastic member 13242. One end of the second connecting member 13241 is connected to the second driving member 133. One end of the second elastic member 13242 is connected to the second vertical plate 1322, and the other end is connected to the other end of the second connecting member 13241.

[0044] For example, both the first buffer 1224 and the second buffer 1324 can be buffer mechanical components with elastic buffering elements, which can absorb the impact force when the first driving member 123 and the second driving member 133 move, thereby playing a buffering role. For example, both the first connecting member 12241 and the second connecting member 13241 can be a rectangular metal block. Both the first elastic member 12242 and the second elastic member 13242 can be a rectangular spring assembly. For example, the rectangular spring assembly can include four rectangular springs.

[0045] Through the above embodiments, this application reduces the acceleration impact force during the start-stop process of the drive component by setting a buffer, thereby reducing the displacement deviation of the shock absorber tube under test caused by the acceleration impact force, thus improving the positioning accuracy and sealing effect.

[0046] Figure 3 A cross-sectional schematic diagram of the second fastener according to an embodiment of this application is shown. According to some embodiments of this application, such as... Figure 1 , Figure 2 and Figure 3 As shown, the first sealing element 1223 includes a first limiting element 12231, a first connecting pipe 12232, and a first sealing ring 12233. The first limiting element 12231 has a first circular through hole 122311, the diameter of which matches the outer diameter of the shock absorber tube to be tested, thus limiting and fixing one end of the shock absorber tube. The first connecting pipe 12232 is disposed on the first vertical plate 1222, one end of which is connected to an external air pressure regulating device, and the other end is inserted into the first circular through hole 122311. The first sealing ring 12233 is inserted into the first circular through hole 122311.

[0047] The second sealing element 1323 includes a second limiting element 13231, a second connecting pipe 13232, and a second sealing ring 13233. The second limiting element 13231 has a second circular through hole 132311, the diameter of which matches the outer diameter of the shock absorber tube to be tested, thus limiting and fixing the other end of the shock absorber tube. The second connecting pipe 13232 is disposed on the second vertical plate 1322, one end of which is connected to an external air pressure regulating device, and the other end is inserted into the second circular through hole 132311. The second sealing ring 13233 is inserted into the second circular through hole 132311.

[0048] For example, both the first limiting member 12231 and the second limiting member 13231 can be rectangular metal blocks with circular through holes. Both the first connecting pipe 12232 and the second connecting pipe 13232 can be hollow vent pipes to connect the external air pressure regulating device and the shock absorber pipe under test. For example, both the first sealing ring 12233 and the second sealing ring 13233 can be star-shaped sealing rings.

[0049] Through the above embodiments, this application uses a limiting component to limit the position of the shock absorber tube under test, thereby reducing the displacement of the shock absorber tube during the test. The sealing ring is used to seal the end of the shock absorber tube under test, reducing the probability of gas leakage.

[0050] Figure 4 A schematic diagram of the locking assembly according to an embodiment of this application is shown. According to some embodiments of this application, such as... Figure 4 As shown, the shock absorber airtightness testing device 1 also includes a locking assembly 14. The locking assembly 14 is disposed on the base 11 and clamps and fixes the shock absorber to be tested.

[0051] Through the above embodiments, this application further locks and fixes the shock absorber tube under test by setting a locking component, thereby reducing the probability of the shock absorber tube under test bending and deforming during the test.

[0052] According to some embodiments of this application, such as Figure 1 and Figure 4 As shown, the locking assembly 14 includes a first locking member 141 and a second locking member 142. The first locking member 141 is disposed on the base 11 and clamps and fixes the shock absorber tube to be tested at a first position. The second locking member 142 is disposed on the base 11 and is disposed opposite to the first locking member 141, clamping and fixing the shock absorber tube to be tested at a second position.

[0053] For example, both the first locking member 141 and the second locking member 142 may include a clamping mechanism, which locks and fixes the shock absorber tube under test. Exemplarily, the clamping mechanism may be a latch or a snap-fit. For example, the first position may be the position corresponding to one end of the base 11 where the shock absorber tube under test is located. The second position may be the position corresponding to the other end of the base 11 where the shock absorber tube under test is located.

[0054] Through the above embodiments, this application achieves multi-dimensional stability control during the testing of shock absorbers by designing the relative position layout of the double locking structure, thereby improving the stability of the shock absorber under test against displacement during the testing process.

[0055] According to some embodiments of this application, such as Figure 1 and Figure 4As shown, the first locking member 141 includes a first locking base 1411 and a first latch 1412. The first locking base 1411 is disposed on the base 11 and has a first groove 14111. The first latch 1412 is disposed on the first locking base 1411 and has a second groove 14121. The second locking member 142 includes a second locking base 1421 and a second latch 1422. The second locking base 1421 is disposed on the base 11 and has a third groove 14211. The second latch 1422 is disposed on the second locking base 1421 and has a fourth groove 14221. When the first buckle 1412 is closed, the first groove 14111 and the second groove 14121 cooperate to fix the first position of the shock absorber tube under test. When the second buckle 1422 is closed, the third groove 14211 and the fourth groove 14221 cooperate to fix the second position of the shock absorber tube under test.

[0056] For example, both the first locking base 1411 and the second locking base 1421 can have a fixed metal base for supporting and fixing. The first latch 1412 can be movably connected to the first locking base 1411 via a hinge axis. The second latch 1422 can be movably connected to the second locking base 1421 via a hinge axis. For example, the first groove 14111 and the second groove 14121 can be complementary grooves; for example, both the first groove 14111 and the second groove 14121 can be V-shaped grooves or semi-circular grooves. The third groove 14211 and the fourth groove 14221 can be complementary grooves; for example, both the third groove 14211 and the fourth groove 14221 can be V-shaped grooves or semi-circular grooves.

[0057] Through the above embodiments, this application improves the clamping stability of the shock absorber tube under test by setting complementary grooves for multi-dimensional stable clamping.

[0058] Figure 5 A schematic diagram of the structure of the base according to an embodiment of this application is shown. According to some embodiments of this application, such as... Figure 5 As shown, the base 11 is provided with a first mounting slot 111 for mounting a first driving member 123. A second mounting slot 112 is used for mounting a second driving member 133. A third mounting slot 113 is used for mounting a first fixing component 12 and a first locking member 141. A fourth mounting slot 114 is used for mounting a second fixing component 13 and a second locking member 142.

[0059] Through the above embodiments, this application designs different mounting slots on the base to fix the driving component, fixing component and locking component respectively. This independent mounting position design reduces vibration transmission and thus improves the structural stability of the shock absorber airtightness detection device.

[0060] According to some embodiments of this application, such as Figure 5 As shown, the base 11 is provided with weight reduction holes 115.

[0061] Through the above embodiments, this application reduces the overall weight of the shock absorber air tightness testing device by designing weight reduction holes on the base, thereby reducing the consumables in the production process of the shock absorber air tightness testing device and thus reducing the manufacturing cost.

[0062] According to some embodiments of this application, such as Figure 1 As shown, the shock absorber airtightness testing device 1 also includes a reversing valve 15. The reversing valve 15 is disposed on the base 11 and connected to the first drive member 123 and the second drive member 133. The reversing valve 15 is connected to an external drive mechanism, which adjusts the driving direction of the first drive member 123 and the driving direction of the second drive member 133 through the reversing valve 15.

[0063] Alternatively, the reversing valve 15 may also be fixed to the first drive member 123 or the second drive member 133.

[0064] For example, the external drive mechanism can be a control device that drives the first drive member 123 and the second drive member 133 to move. Exemplarily, the external drive mechanism can be a cylinder controller or an electric cylinder controller.

[0065] Through the above embodiments, this application changes the driving direction of the first driving member and the second driving member by setting a reversing valve, thereby changing the movement direction of the first fixing member and the second fixing member, and thus realizing the fixing and release of the shock absorber tube under test.

[0066] Finally, it should be noted that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or make equivalent substitutions for some of the technical features.
