[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. Example 1

[0027] Please refer to Figures 1-7As shown, an automatic detection device for pneumatic valves includes a workbench 1. A translation mechanism 2 is installed in the middle of the workbench 1. The translation mechanism 2 includes a guide rail 201. A detection mechanism 3 is installed at the upper end of the guide rail 201. The detection mechanism 3 includes a mounting frame 301. The mounting frame 301 is slidably connected to the upper end of the guide rail 201. A rotating shaft 304 is rotatably connected to the inner side of the upper end of the mounting frame 301. A turntable 303 is fixedly connected to the middle of the outer side of the rotating shaft 304. Several sets of detection air cylinders 308 are installed inside the turntable 303. The sizes of the multiple sets of detection air cylinders 308 are different, and a connecting nozzle 311 is fixedly connected to the right side of each set of detection air cylinders 308. A mounting platform 101 is provided on the left side of the workbench 1, and a support platform 102 is provided on the right side. A clamping mechanism 4 is installed at the upper end of the mounting platform 101, and an inflation component 5 is installed at the upper end of the support platform 102.

[0028] In this solution, the inflation assembly 5 can inflate the test cylinder 308 through the connecting nozzle 311. The testing mechanism 3 can slide above the guide rail 201, and the clamping mechanism 4 can clamp and fix the pneumatic valve. During testing, firstly, according to the model and size of the pneumatic valve, the turntable 303 is rotated to move the test cylinder 308 that meets the requirements on the turntable 303 to the top, so that the test cylinder 308 and the pneumatic valve are on the same axis. Then, the mounting bracket 301 moves to the left, thereby driving the turntable 303 and multiple sets of test cylinders 308 to the left through the rotating shaft 304, so that the left side of the test cylinder 308 is tightly attached to one end of the pneumatic valve, and inflated through the inflation assembly 5. The gas enters the test cylinder 308 through the connecting nozzle 311 and then enters the pneumatic valve. At this time, the change of the pressure gauge 309 can be observed to observe whether there is any leakage, so as to distinguish whether the pneumatic valve is qualified or unqualified, and to test different models of pneumatic valves. Example 2

[0029] Please refer to Figure 4 and Figure 5 As shown, a second servo motor 306 is fixedly mounted on the right side of the mounting bracket 301. The output end of the second servo motor 306 extends to the inner side of the mounting bracket 301 and is fixedly connected to a drive gear 307. A driven gear 305 is fixedly connected to the outer side of the rotating shaft 304. The drive gear 307 and the driven gear 305 mesh with each other.

[0030] Each of the multiple sets of testing air cylinders 308 has a sealing gasket 310 fixedly connected to its left end, and a pressure gauge 309 fixedly connected to the outside of each of the multiple sets of testing air cylinders 308.

[0031] In this scheme, the second servo motor 306 is electrically connected to an external power source. The second servo motor 306 can drive the driven gear 305 to rotate, thereby driving the driving gear 307 to make the rotating shaft 304 and the turntable 303 rotate. As needed, the matching detection air cylinder 308 can be transferred to the upper end of the turntable 303. The sealing gasket 310 can increase the sealing effect between the detection air cylinder 308 and the pneumatic valve. Example 3

[0032] Please refer to Figure 4 As shown, a drive screw 202 is rotatably connected inside the guide rail 201. A first servo motor 203 is fixedly installed on the right end of the guide rail 201. The output end of the first servo motor 203 extends into the interior of the guide rail 201 and is fixedly connected to the drive screw 202. Two sets of moving blocks 302 are fixedly connected to the lower end of the mounting bracket 301. The moving blocks 302 are threadedly connected to the outside of the drive screw 202.

[0033] In this scheme, the first servo motor 203 is electrically connected to an external power source. The first servo motor 203 can drive the drive screw 202 to rotate, thereby driving the moving block 302 to move the mounting bracket 301. Example 4

[0034] Please refer to Figure 3 As shown, the clamping mechanism 4 includes a guide rod 401, a bidirectional screw 402, and two sets of clamping rods 403. The guide rod 401 is fixedly connected to the inner side of the upper end of the mounting platform 101. The two sets of clamping rods 403 are slidably connected to the outer side of the guide rod 401. A third servo motor 405 is fixedly installed on the outer side of the upper end of the mounting platform 101. The output end of the third servo motor 405 is fixedly connected to the bidirectional screw 402. The bidirectional screw 402 is rotatably connected to the inner side of the upper end of the mounting platform 101. Both ends of the bidirectional screw 402 are threaded with opposite directions of rotation. The two sets of clamping rods 403 are respectively threaded to the outer sides of both ends of the bidirectional screw 402. The right end of both sets of clamping rods 403 is fixedly connected to a jaw 404.

[0035] In this scheme, the third servo motor 405 is electrically connected to an external power source. The third servo motor 405 can drive the bidirectional screw 402 to rotate, thereby driving the two sets of clamping rods 403 and the jaws 404 to move in the same direction and towards each other, thereby clamping and fixing the pneumatic valve. Example 5

[0036] Please refer to Figure 7As shown, the inflation assembly 5 includes an air pump 501 and an electric push rod 502. The electric push rod 502 is fixedly installed on the upper end of the support platform 102. The output end of the electric push rod 502 is fixedly connected to a connecting plate 503. An inflation nozzle 504 adapted to the connecting nozzle 311 is fixedly connected to the outside of the connecting plate 503. The air pump 501 is fixedly installed on the upper end of the support platform 102. The air pump 501 is connected to the inflation nozzle 504 through a connecting hose.

[0037] In this scheme, the electric push rod 502 is electrically connected to an external power source. The electric push rod 502 can drive the connecting plate 503 to move to the left, thereby driving the air inlet 504 to be fitted onto the outside of the connecting nozzle 311. At the same time, the air pump 501 delivers gas to the detection air cylinder 308 and the pneumatic valve to perform the detection.

[0038] The working principle and usage process of this utility model are as follows: First, place the pneumatic valve to be tested on the mounting platform 101. Start the third servo motor 405, which drives the bidirectional screw 402 to rotate, thereby driving the two sets of clamping rods 403 and jaws 404 to move towards each other until the jaws 404 tightly clamp the pneumatic valve and achieve stable fixation. At the same time, according to the model and size of the pneumatic valve, observe the specifications of each set of testing air cylinders 308 on the turntable 303. Start the second servo motor 306, whose output end meshes with the driven gear 305 through the drive gear 307, driving the rotating shaft 304 and the turntable 303 to rotate until the testing air cylinder 308 that meets the requirements is rotated to be directly above the turntable 303 and on the same axis as the pneumatic valve. Then, start the first servo motor 203, whose output end drives the drive screw 202 to rotate. At this time, the first servo motor 203... The system is started, which drives the drive screw 202 to rotate. This causes the moving block 302 to move the test air cylinder 308 on the mounting bracket 301 and turntable 303 to the left until the left side of the test air cylinder 308 is tightly fitted with one end of the pneumatic valve. At this time, the electric push rod 502 is started, and its output end drives the connecting plate 503 to move to the right until the inflation nozzle 504 is fitted on the outside of the connecting nozzle 311. At the same time, the air pump 501 is started, and gas is delivered to the inflation nozzle 504 through the connecting hose. The gas then enters the test air cylinder 308 through the connecting nozzle 311 and then enters the pneumatic valve. By observing the change in the value of the pressure gauge 309, it is determined whether there is a leak in the pneumatic valve. If the value of the pressure gauge 309 remains stable or changes within the allowable range, it indicates that the pneumatic valve is qualified. If the value drops sharply, it indicates that there is a leak and the pneumatic valve is unqualified.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
