[0030] As Figure 1 and Figure 2As shown, a high-precision carburetor air tightness detection machine 10 includes a base 100 and a test assembly 200. The base 100 is provided with a controller. The test assembly 200 includes a carrier 210, a discharge sensor 220, a pressure regulating valve 230, a differential pressure gauge 240, a defective product storage groove 250, a defective product sensor 260, and two electromagnetic valves 270. The carrier 210 is arranged on the base 100 and is used to support the carburetor 20. The discharge sensor 220 is arranged adjacent to the carrier 210 on the base 100. The pressure regulating valve 230, the differential pressure gauge 240, and the two electromagnetic valves 270 are all arranged on the base 100. The two test ends of the differential pressure gauge 240 are connected to the pressure regulating valve 230 through the two electromagnetic valves 270, respectively. One of the test ends of the differential pressure gauge 240 is connected to the carburetor 20. The defective product storage groove 250 is arranged below the base 100. The defective product sensor 260 is arranged at the opening of the defective product storage groove 250. The discharge sensor 220, the differential pressure gauge 240, the defective product sensor 260, and the electromagnetic valves 270 are electrically connected to the controller.
[0031] It should be noted that the carrier 210 is mounted on the base 100 and is used to fix the carburetor 20. In this application, the carrier 210 is a column structure which can be inserted into a through hole of the carburetor 20 to fix it. The discharge sensor 220 is arranged on the base 100 and is distributed adjacent to the carrier 210. In this way, when the carburetor 20 is placed on the carrier 210, the discharge sensor 220 can detect the loading of the carburetor 20 and send a loading signal to the controller. In an embodiment, the controller is a PLC controller. Further, the input end of the pressure regulating valve 230 is used to connect to an external high-pressure gas flow. The output end of the pressure regulating valve 230 is connected to the two electromagnetic valves 270. The two electromagnetic valves 270 are connected to the two test ends of the differential pressure gauge 240, respectively. Further, one of the test ends of the differential pressure gauge 240 is connected to the carburetor 20. Further, for example, the base 100 can be installed on a production line for use. When an air tightness detection defective product appears, the defective product can be directly placed on the production line to remove it. Therefore, the defective product storage groove 250 for connecting to the production line can be opened below the base 100, so that the worker can place the defective product on the production line through the defective product storage groove 250. The defective product sensor 260 is arranged at the opening position of the defective product storage groove 250, for example, the defective product sensor 260 is an infrared sensor. In an embodiment, the test assembly 200 is provided with multiple test assemblies 200 which are arranged with intervals. In this way, one test assembly 200 is one test station, and multiple test assemblies 200 correspond to multiple test stations.
[0032] The working principle of the high-precision carburetor airtightness detection machine 10 of the present application is described as follows: the carburetor 20 is placed on the carrier 210, and the carburetor 20 is communicated with one of the test ends of the differential pressure gauge 240 through a pipeline. High-pressure gas flows into the two test ends of the differential pressure gauge 240 through the pressure regulating valve 230 and the electromagnetic valve 270, respectively. The pressure of the gas flowing in can be adjusted through the pressure regulating valve 230. Then the two electromagnetic valves 270 are closed, and the test end of the differential pressure gauge 240 not communicated with the carburetor 20 is closed to the reference test gas pressure. When the carburetor 20 has good airtightness, it means that the pressure difference between the two test ends of the differential pressure gauge 240 will not exceed the acceptable range, and the differential pressure gauge 240 will send a good product differential pressure signal to the controller; when the carburetor 20 has poor airtightness, it means that the pressure of the test end of the differential pressure gauge 240 communicated with the carburetor 20 will be lower, so that the pressure difference between the two test ends of the differential pressure gauge 240 exceeds the acceptable range, and thus the differential pressure gauge 240 will send a poor product differential pressure signal to the controller, and the controller will send a carburetor 20 poor airtightness signal. The above-mentioned test assembly 200 is a single test station structure. When multiple test stations are set, it means that there are multiple test assemblies 200. Since each test assembly 200 is isolated by the electromagnetic valve 270, the stations will not affect each other, and the test precision and stability can be effectively improved. Further, when the pipelines between multiple stations are correctly connected to the carburetor 20 at the corresponding position, since the values of the material discharge sensor 220 of each station and the differential pressure gauge 240 of each station are one-to-one corresponding, once the good product carburetor 20 is mistakenly removed (the good product differential pressure signal of the differential pressure gauge 240 is sent to the controller) and placed in the poor product storage slot 250 (the material entry signal of the poor product sensor 260 is sent to the controller), the controller can determine that the good product is mistakenly put into the poor product storage slot 250, and thus an incorrect material entry warning is issued. Further, when the pipelines between multiple stations are cross-connected to the carburetor 20 of other stations, in order to facilitate description, two stations are taken as an example for description, which are defined as a first station and a second station, respectively. The differential pressure gauge 240 of the first station is communicated with the carburetor 20 of the second station, and the differential pressure gauge 240 of the second station is communicated with the carburetor 20 of the first station, which is the cross-connection case. If the carburetor 20 located in the first station is a good product, since the differential pressure gauge 240 of the second station is communicated with the carburetor 20 of the first station, the differential pressure gauge 240 of the second station will send a good product differential pressure signal to the controller, and the carburetor 20 located in the second station is a poor product, since the differential pressure gauge 240 of the first station is communicated with the carburetor 20 of the second station, the differential pressure gauge 240 of the first station will send a poor product differential pressure signal to the controller.Since the operator does not know that the cross connection occurs, when the carburetor 20 at the first station is mistakenly pulled out and put into the defective product storage groove 250, but the carburetor 20 at the first station is actually communicated with the differential pressure gauge 240 at the second station, the differential pressure of the differential pressure gauge 240 at the second station will sharply increase due to the pulling out of the carburetor 20, so the controller can determine that the carburetor 20 is pulled out, and thus a warning signal of the mistaken putting of the carburetor 20 can be sent. In this way, the good product and the defective product are prevented from being mistakenly put, and the good product is prevented from being mistakenly put into the defective product storage groove 250.
[0033] As shown in Figure 1 and Figure 2 , in an embodiment, the testing assembly 200 further comprises a pressing driving member 281 and a plug 282, the pressing driving member 281 is arranged on the base 100, the plug 282 is arranged on the output shaft of the pressing driving member 281, and the plug 282 is above the carrier 210.
[0034] It should be noted that in order to plug the part where the carburetor 20 is communicated with the outside, the pressing driving member 281 is installed to drive the plug 282 to approach or move away from the carrier 210, and when the plug 282 is lowered, the plug 282 can plug the carburetor 20. In an embodiment, the pressing driving member 281 is a pneumatic cylinder.
[0035] As shown in Figure 2 and Figure 3 , in an embodiment, the testing assembly 200 further comprises a marking driving member 283 and a marking needle 284, the marking driving member 283 is arranged on the base 100, the marking needle 284 is arranged on the output shaft of the marking driving member 283, and the marking driving member 283 is used to drive the marking needle 284 to approach or move away from the carburetor 20.
[0036] It should be noted that the marking needle 284 is provided with a sharp needle, and when the marking needle 284 is driven by the marking driving member 283 to approach the carburetor 20, the marking needle 284 can mark the specified position of the carburetor 20. For example, the marking driving member 283 is also a pneumatic cylinder.
[0037] As shown in Figure 3 , in an embodiment, a protective sleeve 285 is further sleeved on the output shaft of the marking driving member 283, and the marking needle 284 is located in the protective sleeve 285.
[0038] It should be noted that in order to avoid the carburetor 20 being mistakenly injured by the marking needle 284 when the carburetor 20 is placed on the carrier 210, a protective sleeve 285 is installed on the output shaft of the marking driving member 283, so that the marking needle 284 is located in the protective sleeve 285.
[0039] As shown in Figure 3As shown, in one embodiment, the test assembly 200 further includes a multi-axis bracket 286, which is disposed on the base 100, and the marking drive 283 is disposed on the multi-axis bracket 286.
[0040] It should be noted that, for example, the multi-axis bracket 286 is a five-axis structure. Through the multi-axis bracket 286, the marking drive 283 can be adjusted to face any direction, so that the high-precision carburetor air tightness testing machine 10 of this application can be used to test multiple models of carburetors 20.
[0041] like Figure 2 As shown, in one embodiment, the test assembly 200 further includes a first tap 287, through which the pressure regulating valve 230 and two solenoid valves 270 are connected.
[0042] It should be noted that, for example, the first tap 287 is a three-way connector, which allows the pressure regulating valve 230 to be conveniently connected to both solenoid valves 270 simultaneously. Furthermore, in one embodiment, one test terminal of the differential pressure gauge 240, the carburetor 20, and one solenoid valve 270 are also connected via a three-way connector. Further, the other test terminal of the differential pressure gauge 240 and the other solenoid valve 270 are also connected via a three-way connector; simply blocking one passage of this three-way connector ensures stable connection between the other test terminal of the differential pressure gauge 240 and the other solenoid valve 270.
[0043] like Figure 1 As shown, in one embodiment, the high-precision carburetor air tightness testing machine 10 also includes a main pressure valve 310 and a main solenoid valve 320. The main pressure valve 310 is connected to the main solenoid valve 320, and each pressure regulating valve 230 is connected to the main solenoid valve 320.
[0044] Thus, the air pressure of each test component 200 can be adjusted simultaneously via the main pressure valve 310. In one embodiment, the structure of the main pressure valve 310 is equivalent to that of the pressure regulating valve 230. Further, in one embodiment, the structure of the main solenoid valve 320 is equivalent to that of the solenoid valve 270.
[0045] like Figure 1 As shown, in one embodiment, an electrical control box 330 is also provided on the base 100, with the controller disposed inside the electrical control box 330. The main pressure valve 310 and the main solenoid valve 320 are both disposed on the outer wall of the electrical control box 330. In this way, installing the controller inside the electrical control box 330 can ensure the safety of the controller and the electrical control system.
[0046] like Figure 1As shown, the top of the electric control box 330 is provided with a warning light 340, which is electrically connected with the controller. In this way, when the good carburetor 20 is mistakenly put into the bad product storage groove 250, the controller can send a light warning signal through the warning light 340. Further, a buzzer can also be installed on the electric control box 330 to send a sound warning signal.
[0047] The above-described embodiments only express several embodiments of the present application, which are described in more detail and in more detail, but cannot be understood as limiting the scope of the application. Among them, the installation / fixing / setting in the present application can be understood as including but not limited to locking and fixing by using screws / screws, welding, unless otherwise defined.
