[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Example 1 refer to Figures 1-4 This utility model provides a portable pneumatic parts testing device, including a testing housing 10. The testing housing 10 is provided with a power input interface 20, an air source input interface 30, an air source output interface 40, and a testing unit. The power input interface 20 is used to connect to an external power source to supply power for testing, and the air source input interface 30 is used to connect to an external air source to supply air for testing pneumatic parts. This device is easy to carry and move, and can be connected to the on-site power and air sources to complete the testing preparation. It achieves portability and integrated design, and improves testing efficiency.

[0025] Specifically, the power input interface 20 and the air source input interface 30 are both located on the input side of the testing chamber 10, and the air source output interface 40 is located on the output side of the testing chamber 10 for easy connection and operation. The power input interface 20 and the air source input interface 30 are both connected to the air source output interface 40 through the testing unit, which is located in the testing chamber 10 and is used to switch the air supply on and off, so that the air source input interface 30 and the air source output interface 40 are connected or disconnected, so as to realize the execution or maintenance of the action during the testing of pneumatic parts, reduce the testing difficulty, and improve the testing efficiency.

[0026] To further explain, the detection unit includes a power switch 50 and a solenoid valve 60. The gas source input interface 30 is connected to the gas source output interface 40 through the solenoid valve 60, and the power input interface 20 is electrically connected to the solenoid valve 60 through the power switch 50.

[0027] The power switch 50 controls the power supply to the solenoid valve 60, thereby controlling the on / off state of the gas source. It is simple, convenient and low-cost to operate, prevents the waste of gas source in non-detection state, and improves the reliability and stability of detection.

[0028] To further explain, a counter 61 is provided on the operating end face of the testing chamber 10. The counter 61 is electrically connected to the power input interface 20 and is powered by an external power source. The solenoid valve 60 is electrically connected to the counter 61 and can display the number of times the solenoid valve 60 has been opened and closed. This can be used as a measure of the number of times the pneumatic parts have been operated, which facilitates data statistics, meets the fatigue testing requirements of pneumatic parts, and ensures accurate and reliable testing.

[0029] Specifically, a counter switch 62 is also provided on the operating end face of the detection box 10, and the counter 61 is electrically connected to the power input interface 20 through the counter switch 62.

[0030] During the testing process, the counter display can be turned on or off via the counter switch 62 as needed. Alternatively, by turning off the counter switch 62, the counter value can be reset to zero when the counter 61 is turned on again, facilitating new testing and meeting different testing requirements.

[0031] To further explain, the power supply switch 50 includes a relay 51, and the portable pneumatic parts testing device also includes a timer controller 70; both the timer controller 70 and the relay 51 are located inside the testing box 10, the power input interface 20 is electrically connected to the power-on terminal of the timer controller 70, and the power-off terminal of the timer controller 70 is electrically connected to the solenoid valve 60 through the relay 51.

[0032] Specifically, by using relay 51 and timer controller 70 together, the switching time can be adjusted by timer controller 70 as needed, thereby using relay 51 to control the switching of solenoid valve 60, realizing the detection of pneumatic parts, further improving detection efficiency and reducing detection difficulty; timer controller 70 can be selected as TPC4-4TD.

[0033] The power supply switch 50 also includes a detection switch 52. The power transmission terminal of the timer controller 70 is electrically connected to the relay 51 through the detection switch 52. The detection switch 52 is set on the operating end face of the detection box 10. The operator can start or stop the detection of pneumatic parts by manually opening or closing the detection switch to ensure reliable detection and stop the detection operation in time to ensure detection safety.

[0034] To further explain, since cylinder-type products have multiple action positions, in actual use, a magnetic switch is installed inside the cylinder, and a magnetic receiving unit is installed outside the cylinder at the corresponding position. The current position can be obtained by determining which position's magnetic receiving unit the magnetic switch inside the cylinder is aligned with. In order to ensure that the pneumatic parts are supplied with air to perform the required actions during the testing process, the testing unit also includes a magnetic receiving switch 71. The magnetic receiving switch 71 is electrically connected to the relay 51 through a timer controller 70. The magnetic receiving switch 71 can be set to the required execution position during the testing process. When the pneumatic parts are supplied with air to perform the required action, the solenoid valve 60 closes. When the pneumatic parts return to their original position, the solenoid valve 60 reopens, and the pneumatic parts perform the action again, thus fulfilling the testing requirements of cylinder-type parts.

[0035] Preferably, a heat dissipation grille 80 is provided on the detection chamber 10, and the heat dissipation grille 80 is connected to the interior of the detection chamber 10 to dissipate the heat generated inside.

[0036] Example 2 refer to Figures 1-5 Based on the portable pneumatic parts testing device provided in Embodiment 1, this embodiment provides a portable pneumatic parts testing device with multiple testing units and multiple air source output interfaces 40. The multiple testing units are arranged in parallel, and multiple testing switches 52 are electrically connected to the power supply terminal of the timing controller 70 through signal terminal blocks 72. Multiple solenoid valves 60 are respectively connected to multiple air source output interfaces 40 one by one, thereby enabling the synchronous testing of multiple pneumatic parts and further improving the testing efficiency. The following description takes four testing units as an example.

[0037] The testing housing 10 is equipped with a primary air switch 21, an AC terminal block 22, an AC to DC converter 23, and a DC terminal block 24. The power input interface 20 is electrically connected to the AC terminal block 22 via the air switch 21, and the DC terminal block 24 is electrically connected to the testing unit.

[0038] Circuit protection is achieved using air switch 21, which also serves as the main switch for detection. Each detection unit is electrically connected to the timing controller 70 through a detection switch, thereby realizing single-channel detection control, which is convenient to operate and can detect different numbers of parts according to requirements.
