[0023] Please refer to Figures 1 to 3 As shown, this embodiment provides a padlock testing machine, including: a machine base 1; a key clamping component, which includes a first hydraulic cylinder 2 fixedly mounted on the top of the machine base 1, the telescopic end of the first hydraulic cylinder 2 is fixedly connected to a driving motor 3 through a first connecting plate 201, and the output shaft of the driving motor 3 is fixedly connected to a pneumatic clamp 4 through a second connecting plate 301; a lock hook pushing component, which includes a test bench 5 fixedly mounted on the top of the machine base 1, a second hydraulic cylinder 6 is fixedly mounted on the top of the test bench 5, and a push plate 7 is fixedly connected to the telescopic end of the second hydraulic cylinder 6; and a lock body fixing component, which includes a mounting frame 9 fixedly mounted on the top of the machine base 1, a third hydraulic cylinder 901 is fixedly mounted on the mounting frame 9, a pressing plate 902 is fixedly connected to the telescopic end of the third hydraulic cylinder 901, and the pressing plate 902 is pressed down to contact the lock body of the padlock 10; wherein the padlock 10 is mounted on the top of the test bench 5, the lock hook of the padlock 10 faces the push plate 7, and the key port faces the pneumatic clamp 4; wherein a positioning portion for quickly placing the padlock 10 is provided on the test bench 5.
[0024] The utility model can test the padlock by machine instead of manual labor through the coordinated use of the key clamping component, the lock hook pushing component and the lock body fixing component, thus saving time and labor, improving the padlock detection efficiency and reducing the production cost.
[0025] Specifically, Figure 1As shown, a slide groove 101 is provided on the top of the base 1, a slider 102 is slidably installed inside the slide groove 101, and the top of the slider 102 is fixedly connected to the bottom of the first connecting plate 201. The above design, through the arrangement of the slide groove 101 and the slider 102, can increase the stability of the output of the first hydraulic cylinder 2, thereby ensuring the stability of the pneumatic clamp 4 in clamping, rotating and inserting the key of the padlock 10.
[0026] Specifically, Figure 2 As shown, the positioning portion is a positioning groove 501 provided on the top of the test bench 5 and used in conjunction with the padlock 10 body, and the padlock 10 is engaged and clamped in the positioning groove 501. In the above design, the positioning groove 501 is used to quickly position the padlock 10, thereby improving the test efficiency and accuracy. In addition, the positioning groove 501 is used in conjunction with the pressing plate 902 to further increase the firmness of the padlock 10.
[0027] Specifically, Figure 2 The top of the test bench 5 is fixedly mounted with a fixing plate 502, a linear bearing 503 is fixedly mounted on the fixing plate 502, a guide rod 701 is fixedly mounted on the back side of the push plate 7, and the guide rod 701 is movably mounted in the inner ring of the linear bearing 503.

[0031] It is worth noting that the model of the pneumatic gripper 4 may be MHZ2-20D;
[0032] This padlock testing machine is suitable for production testing of rust-proof and dust-proof padlocks, fine iron padlocks, anti-knock dual system padlocks, reinforced high tensile waterproof padlocks, reinforced high tensile waterproof padlocks and anti-theft short beam mechanical padlocks.
[0033] As is well known to those skilled in the art, the working principles and wiring methods of the first hydraulic cylinder 2, the drive motor 3, the pneumatic clamp 4, the second hydraulic cylinder 6 and the third hydraulic cylinder 901 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can select their models arbitrarily according to their needs or convenience.
[0034] Working principle: Figure 1-3 As shown, when in use, the padlock 10 to be tested is placed inside the top positioning groove 501 of the test bench 5, the lock hook of the padlock 10 faces the push plate 7, and the key port faces the pneumatic clamp 4, and then the third hydraulic cylinder 901 is started to drive the pressure plate 902 to press, so that the pressure plate 902 presses and fixes the padlock 10 on the test bench 5, and then the first hydraulic cylinder 2 is started to drive the pneumatic clamp 4 to approach the padlock 10, and the pneumatic clamp 4 is started to clamp the key on the padlock 10, and then the drive motor 3 is started. The pneumatic clamp 4 is driven to rotate, and then the pneumatic clamp 4 drives the key to rotate and unlock. When the lock hook of the padlock 10 is opened, the push plate 7 is driven to push in the direction of the lock hook of the padlock 10 by starting the second hydraulic cylinder 6, and the pop-up lock hook is pushed back into the padlock 10 to lock it, and then the push plate 7 is reset, and the drive motor 3 and the first hydraulic cylinder 2 are started again to output, and the key is pulled out from the padlock 10 and reinserted, and the above operation is repeated to complete the detection of the padlock 10.
