Common position sensors include displacement sensors, angle sensors, and velocity sensors. High-precision position sensors are widely used in practical applications, including mechanical control, automotive navigation, robotics, and aerospace.

[0003] In the production and manufacturing of high-precision position sensors, some sensor housings have certain water tightness requirements. The sensor housing needs to be tested for air tightness. Currently, the main method for air tightness testing in water tanks is to use an additional air pump and corresponding control system for air supply testing, which results in high overall equipment costs.

[0026] The high-precision position sensor detection device according to an embodiment of this application is described below with reference to the accompanying drawings.

[0028] The main frame 10 supports the installation of the lifting and adjusting mechanism 20. The lifting and adjusting mechanism 20, through the cooperation of the inflation mechanism 30 and the detection placement mechanism 40, can inject gas into the sensor housing during mechanical lifting for detection, without the need for additional air pumps or other air supply equipment and control components, thus effectively reducing equipment costs.

[0029] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The main frame mechanism 10 includes a platform 110, leg supports 120, a horizontal plate 130, and a support column 140. The leg supports 120 are welded to the bottom of the platform 110, the horizontal plate 130 is located above the platform 110, and the support column 140 is bolted to connect the platform 110 and the horizontal plate 130. The lifting and adjusting mechanism 20 includes a top plate 210, a hydraulic cylinder 220, an upper upright 230, a first plate 240, a second plate 250, a lower upright 260, an elastic connector 270, a vertical frame 280, and a piston 290. The hydraulic cylinder 220 is mounted above the horizontal plate 130, and the top plate 210 is fixed to the top of the output rod end of the hydraulic cylinder 220. Two sets of upper uprights 230 are bolted to the lower sides of the top plate 210, and the first plate 240 is fixed to the bottom of the upper upright 230. The elastic connector 270 connects the first plate 240 and the second plate 250. The top of the lower upright 260 is fixedly connected to the bottom of the second plate 250, and the bottom of the lower upright 260 slides vertically through the horizontal plate 130. The top of the vertical frame 280 is fixedly connected to the first plate 240, and the bottom of the vertical frame 280 slides vertically through the horizontal plate 130. The piston 290 is located at the bottom of the vertical frame 280. The inflation mechanism 30 includes a support plate 310, a cylindrical shell 320 with an open top, an upper plate 330, a first sealing gasket 340, and a vent pipe 350. The support plate 310 is located below the horizontal plate 130, and the bottom of the lower upright 260 is fixedly connected to the support plate 310 with bolts. The cylindrical shell 320 is installed above the support plate 310, and the piston 290 moves vertically in and out of the cylindrical shell 320. The upper plate 330 is fixed to the bottom of the support plate 310, and the first sealing gasket 340 is disposed on the lower surface of the upper plate 330. The top end of the vent pipe 350 is connected to the bottom of the cylinder shell 320, and the bottom end of the vent pipe 350 passes through the upper plate 330 and the first sealing gasket 340 respectively. The detection placement mechanism 40 includes a water tank 410 with an open top, a placement plate 420, an elastic support member 430, a lower plate 440, a second sealing gasket 450, and a positioning member 460. The water tank 410 is disposed above the platform 110, and the water tank 410 has a transparent body for easy viewing of the detection results. The placement plate 420 is located inside the water tank 410, and the elastic support member 430 elastically supports the placement plate 420. The lower plate 440 is fixed above the placement plate 420 and is located directly below the upper plate 330. The second sealing gasket 450 is set on the upper surface of the upper plate 330. Multiple sets of positioning members 460 are arranged in a ring array on the outside of the lower plate 440 and installed above the placement plate 420.

[0030] The working principle of this high-precision position sensor detection device is as follows: Water tank 410 is pre-stored with clean water. The sensor housing to be tested is placed above the second sealing gasket 450 of the lower plate 440, and fixed by the positioning component 460. The second sealing gasket 450 is used to seal the port at the bottom of the sensor housing. The output rod of hydraulic cylinder 220 drives the upper plate 210 to gradually move downwards, and the downward-moving top plate 210 drives the lower upper upright 230 to gradually move downwards. The downward-moving upper upright 230, through the cooperation of the first plate 240, elastic connector 270, second plate 250, and lower upright 260, drives the support plate 310 to gradually move downwards until the first sealing gasket 340 below the upper plate 330 at the bottom of the support plate 310 covers the top port of the sensor housing, and at this time, the bottom end of the vent pipe 350 is located inside the sensor housing.

[0031] Simultaneously, the downward-moving upper rod 230, through the cooperation of the first plate 240 and the vertical frame 280, drives the piston 290 to move downward in sync until the first sealing gasket 340 under the upper plate 330 covers the top port of the sensor housing. Then, the hydraulic cylinder 220 continues to drive the top plate 210 downward. At this point, because the elastic connecting piece 270 between the first plate 240 and the second plate 250 is elastically compressed, and the elastic support pieces 430 on both sides of the placement plate 420 are also compressed, the components on the placement plate 420 and the sensor housing gradually and slowly move downward and are immersed in the clean water of the water tank 410. At the same time, the first plate 240 continues to drive the vertical frame 280 and the piston 290 downward. When the piston 290 enters the cylinder shell 320, the bottom of the sensor housing must be above the water surface. As the piston 290 gradually moves downwards into the cylinder 320, the air inside the cylinder 320 is compressed and enters the sensor housing through the vent pipe 350. This continues until the sensor housing on the placement plate 420 is also gradually lowered and completely immersed in the water. After the water level stabilizes, the hydraulic cylinder 220 continues to drive the piston 290 downwards a certain distance via the vertical frame 280 (depending on the diameter of the sensor housing, the distance the hydraulic cylinder 220 drives the piston 290 to move at this time is about 2cm to 3cm). Through the transparent water tank 410, observe whether there are bubbles emerging from the outer wall and bottom edge of the sensor housing weld. If no bubbles emerge, it means that the workpiece has no cracks. If bubbles emerge, it means that there are gaps in the sensor housing. After the test is completed, the output rod of the hydraulic cylinder 220 drives the components above the support plate 310 to move upward through the cooperation of various components. At the same time, the elastic support 430, which is relieved of pressure, elastically supports the placement plate 420 to move upward. The sensor housing on the placement plate 420 moves upward and is exposed above the water surface. The sensor housing is placed and removed above the water surface. The operator does not need to put his hand into the clean water inside the water tank 410, making the operation more convenient and cleaner.

[0032] This high-precision position sensor detection device can effectively detect the airtightness of the sensor housing without the need for pneumatic equipment such as air pumps, using a relatively simple mechanical structure, thus saving equipment costs.

[0033] In the above specific implementation method, please refer to Figure 8 The positioning component 460 includes an L-shaped bracket 461, a guide rod 462, a third spring 463, a clamping plate 464, and an end cap 465. The bracket 461 is fixed above the placement plate 420, and the guide rod 462 slides through the bracket 461 along the radial position of the lower plate 440. The clamping plate 464 is welded to one end of the guide rod 462 near the lower plate 440, and the end cap 465 is located at the other end of the guide rod 462. The third spring 463 is sleeved on the outside of the guide rod 462 located between the bracket 461 and the clamping plate 464. The third spring 463 applies elastic force to the clamping plate 464, enabling the clamping plate 464 in the multiple positioning components 460 to clamp and fix the sensor housing in multiple directions.

[0034] Furthermore, the positioning component 460 also includes a guide plate 466, which is inclinedly disposed on the top of the clamping plate 464. The inclined guide plate 466 is designed to facilitate the insertion of the bottom of the sensor housing into the multiple clamping plates 464 along the inclined surface of the guide plate 466. In this case, the guide rod 462 is preferably a prismatic structure rod, which prevents the position of the guide plate 466 from easily rotating or shifting.

[0035] In some embodiments of this application, please refer to Figure 3 The elastic connector 270 includes a first spring 271 and a first guide post 272. The bottom end of the first guide post 272 is fixedly connected to the top of the second plate 250, and the top end of the first guide post 272 extends through the first plate 240. A first limiting block 273 is provided at the top end of the first guide post 272. The first spring 271 is sleeved on the outside of the first guide post 272 located between the first plate 240 and the second plate 250. The first spring 271 in the elastic connector 270 realizes the elastic connection between the first plate 240 and the second plate 250; the first guide post 272 is provided to prevent the compressed first spring 271 from deflecting radially.

[0036] Specifically, please refer to Figure 6 A water inlet pipe 480 and a drain pipe 470 are respectively installed on one side of the water tank 410, and a valve is installed on the drain pipe 470. The water inlet pipe 480 is connected to an external water source and is used to inject clean water into the water tank 410, while the drain pipe 470 is used to drain the water from the water tank 410.

[0037] For specific settings, please refer to Figure 2The vertical frame 280 includes a fixing block 281 and a vertical rod 282. The fixing block 281 is bolted to the first plate 240, and the top end of the vertical rod 282 is bolted to the fixing block 281. The bottom end of the vertical rod 282 slides through the horizontal plate 130, and a piston 290 is located at the bottom end of the vertical rod 282. That is, the first plate 240, which moves vertically, drives the piston 290 at the bottom to move vertically through the fixing block 281 and the vertical rod 282.

[0038] Further, please refer to Figure 4 A first ear plate 360 ​​is provided on the outer side of the bottom of the cylindrical shell 320, and the first ear plate 360 ​​is fixedly connected to the support plate 310 by bolts. A second ear plate 370 is provided on the outer side of the upper plate 330, and the second ear plate 370 is fixedly connected to the support plate 310 by bolts.

[0039] Specifically, please refer to Figure 7 A connecting block 421 is provided on the outer side of the placement plate 420. The two ends of the elastic support member 430 are respectively connected to the connecting block 421 and the inner bottom wall of the water tank 410. The elastic support member 430 includes a second spring 431, a second guide post 432 and a bottom cover 434. The bottom cover 434 is fixed to the inner bottom wall of the water tank 410. The bottom end of the second guide post 432 is fixedly connected to the bottom cover 434 and slides through the connecting block 421. A second limiting block 433 is provided at the top of the second guide post 432. The second spring 431 is sleeved on the outside of the second guide post 432 located between the bottom cover 434 and the connecting block 421. The second spring 431 in the elastic support 430 is used to elastically support the placement plate 420. The sensor housing placed on the placement plate 420 is lowered into the clear water from above the water surface under the pressure of the hydraulic cylinder 220 and the second spring 431. After the pressure is released, the sensor housing on the placement plate 420 is pushed out to the water surface by the elastic force of the second spring 431.

[0040] When the multiple sets of clamping plates 464 in the positioning component 460 of the above-mentioned high-precision position sensor detection device are used to clamp and fix the sensor housing, it is necessary to manually push the clamping plate 464 to compress the third spring 463 in order to clamp the sensor housing between the multiple clamping plates 464, resulting in low loading efficiency.

[0041] Please see Figure 2 , Figure 5 and Figure 8The high-precision position sensor detection device also includes a clamping linkage auxiliary mechanism 50, which includes a mounting base 510, a pulley 520, a rope 530, a first lifting ring 540, and a second lifting ring 550. The second lifting ring 550 is fixed to the bottom of the support plate 310 by screws. The mounting base 510 is fixed above the placement plate 420 near the rear of the corner bracket 461. The pulley 520 is rotatably mounted above the mounting base 510. The bottom end of the rope 530 passes under the pulley 520 and connects to the end cap 465. The first lifting ring 540 is located at the top of the rope 530, and the first lifting ring 540 and the second lifting ring 550 are hooked together.

[0042] When loading the sensor housing, the output rod of the hydraulic cylinder 220 pushes the top plate 210 upward, causing it to move upward. The upward movement of the top plate 210 drives the upper upright 230, the first plate 240, the elastic connector 270, the second plate 250, and the lower upright 260 to move upward. Finally, the upward movement of the lower upright 260 drives the support plate 310 to move upward. The upward movement of the support plate 310, through the cooperation of the second lifting ring 550 and the first lifting ring 540, pulls the rope 530. The rope 530 pulls the end cap 465 and the guide rod 462, causing the clamping plate 464 to compress the third spring 463 until the gap between the clamping plates 464 can accommodate the sensor housing to be tested. The hydraulic cylinder 220 then stops pushing upward. At this point, the sensor housing can be placed directly on top of the second sealing gasket 450 on the lower plate 440. When the output rod of the hydraulic cylinder 220 drives the top plate 210 downward to perform the detection operation, the force of the third spring 463 will cause the clamping plate 464 to gradually move and clamp the placed sensor housing. At this time, the rope 530 gradually relaxes to release the tension. When unloading, the rod end of the hydraulic cylinder 220 rises to push the top plate 210 until the rope 530 drives the clamping plate 464 to move and compress the third spring 463 without contacting the outer wall of the sensor housing. At this time, it is convenient to remove the tested sensor housing for unloading. Compared with manually pushing the clamping plate 464 to place the sensor housing, this clamping linkage auxiliary mechanism 50, together with the hydraulic cylinder 220 and related components, can open the clamping plate 464, which is convenient for loading and placing the sensor housing and unloading and removing the tested sensor housing, thus improving the loading and unloading efficiency.

[0043] When the hydraulic cylinder 220 in the aforementioned high-precision position sensor detection device pushes the placement plate 420 into the water, and when the placement plate 420 is ejected from the water surface by the elastic force of the elastic support member 430, the movement of the placement plate 420 can easily cause water stains inside the water tank 410 to splash out from the outer edge of the water tank 410.

[0044] Please see Figure 5 and Figure 9The high-precision position sensor detection device also includes a splash-proof protection mechanism 60, which includes a frame plate 610, a strip box 620 with an open bottom, a float 630, a third ear plate 640, and a third guide post 650. The frame plate 610 is set close to the inner wall of the water tank 410. Two sets of strip boxes 620 are symmetrically fixedly installed on the inner side walls of the frame plate 610. The float 630 is set inside the strip box 620, and the float 630 can be made of foam board with high buoyancy. The third ear plate 640 is fixed to the inner wall of the frame plate 610. The bottom end of the third guide post 650 is fixedly connected to the inner bottom wall of the water tank 410, and the top end of the third guide post 650 moves through the third ear plate 640. A third limiting block is provided at the top end of the third guide post 650.

[0045] When the hydraulic cylinder 220 drives the pallet 310 to press the placement plate 420 below the water surface, the water level inside the water tank 410 rises due to the pressure from multiple components. As the water level rises, the float 630 moves the strip box 620 and frame plate 610 upwards. The upper part of the frame plate 610 protrudes above the outer wall of the water tank 410, preventing water splashes caused by the placement plate 420's movement inside the tank. After the sensor housing completes its detection, the placement plate 420 floats out of the water under the elastic support of the elastic support member 430, and the water level drops. The float 630, along with the frame plate 610, moves downwards, lowering the frame plate 610's height for easier loading and unloading of workpieces. This splash-proof protection mechanism 60 effectively shields against splashes of water generated during the detection process without affecting workpiece loading and unloading, demonstrating good applicability.
