[0039] Example 1

[0040] like Figure 1-3 As shown, this utility model is a lock plate testing device. Through the coordinated operation of a turntable, testing table, testing frame, and testing components, it achieves automated testing of lock plates, effectively improving testing efficiency and accuracy, and reducing manual testing costs and errors. The testing device includes a turntable 1, a testing table 2, a testing frame 3, and testing components 4. Mounting holes 6 are pre-drilled on the turntable 1, testing table 2, and testing frame 3. The turntable 1 includes a movable outer plate 11 and a fixed inner plate 12. Testing stations 14 are provided on the movable outer plate 11. The rotation cycle of the movable outer plate 11 is 23 seconds, and the rotation distance is the interval between testing stations. Each testing station 14 is equipped with a testing fixture 13 adapted to lock plates of different specifications. The testing fixture 13 can stably fix the lock plate, preventing displacement during testing and ensuring the reliability of the testing results.

[0041] The inspection station 14 is equipped with an inspection frame 3 corresponding to the fixed inner plate 12. This layout allows the locking piece to directly enter the inspection area when the turntable rotates to the corresponding station, reducing the complexity of the inspection process and improving inspection efficiency.

[0042] The testing frame 3 is equipped with a testing component 4, which includes a testing mechanism lifting cylinder 61, an electric cylinder 62, a force sensor 63, a buffer limit device, and connecting parts. The force sensor 63, electric cylinder 62, and testing mechanism lifting cylinder 61 are all connected to a PLC control device. The PLC control device can precisely control the various actions of the testing component 4 and adjust the working status of the electric cylinder 62 and the testing mechanism lifting cylinder 61 in real time, realizing automated control of the lock plate testing process. The connecting parts are provided with connecting holes 7 for fixing. A fixing adjustment device 23 matching the mounting hole is provided at the connection between the testing frame 3 and the fixed inner plate 12. The fixing adjustment device 23 has a horizontal adjustment shaft 24. Through the adjustment shaft 24, the position and angle of the testing frame 3 can be flexibly adjusted according to different models of lock plates, so that the testing component 4 can accurately align with the testing part of the lock plate, greatly improving the versatility and adaptability of the testing device and meeting the testing needs of various specifications of lock plates.

[0043] Example 2

[0044] like Figure 4-5 As shown, the lifting cylinder 61 of the testing mechanism is fixed on the electric cylinder base 411. One end of the electric cylinder base 411 is fixedly connected to the first connecting plate 412 through a connecting hole. The first connecting plate 412 is fixedly connected to the slot on the testing frame 3 through a connector. The lifting cylinder 61 of the testing mechanism can precisely control the lifting of the testing component according to the testing requirements. When the lock plate needs to be tested, the cylinder drives the testing component to descend to a suitable position to ensure the smooth progress of the testing operation. After the test is completed, the cylinder drives the testing component to rise, avoiding collision with the turntable and the lock plate, effectively protecting the testing device and the lock plate.

[0045] A first sliding groove 413 is fixed on the first connecting plate 412, and a first slider 414 is provided on the first sliding groove 413. The first slider 414 is fixedly connected to the second connecting plate 415. A first connecting block 416 is fixed to the end of the telescopic rod of the lifting cylinder 61 of the testing mechanism, and the first connecting block 416 is fixedly connected to the top of the second connecting plate 415. This guide structure of the slider and sliding groove provides precise guidance for the movement of the second connecting plate 415, ensuring the stability and accuracy of the lifting cylinder 61 of the testing mechanism in driving the second connecting plate 415 to rise and fall, effectively reducing the detection error caused by shaking, and further improving the detection accuracy. The bottom end of the second connecting plate 415 is flush with the bottom of the right-angle connector 417 and fixedly connected to the connecting hole on the third connecting plate 418.

[0046] One end of the third connecting plate 418 is connected to the fourth connecting plate 421 through a fixing hole. The fourth connecting plate 421 has a second connecting block 422 and a third connecting block 423 respectively in its middle and tail sections. The second connecting block 422 and the third connecting block 423 fix the head end and the tail end of the electric cylinder 62 respectively. This connection method allows the electric cylinder 62 to be stably installed in the detection assembly 4, improving the displacement accuracy of the electric cylinder 62, reducing the influence of environmental factors during detection, and improving the accuracy of lock plate performance detection. The lower end of the third connecting plate 418 is fixedly connected to the second slide groove 419. The second slide groove 419 is movably connected to the second slide groove 419. The lower ends of the second slide groove 420 are respectively provided with the fourth connecting block 424 and the fifth connecting block 425. The fourth connecting block 424 fixes the force sensor 63, and the force sensor is provided with a lock plate push head. The fifth connecting block 425 is provided with a groove that matches the end of the telescopic rod of the electric cylinder 62. The force sensor 63 is configured to monitor the magnitude of the force applied to the lock plate during the detection process in real time and feed the data back to the PLC control device. Through the linkage of the force sensor, electric cylinder, and PLC control device, and by setting a detection threshold, the cylinder only outputs the detection force within the range, thereby accurately detecting whether the lock plate's contact condition is qualified, thus completing the precision detection of the lock plate. In this embodiment, the lock plate detection force value is 6-9N, which is used to determine whether the lock plate can be activated under 6-9N conditions. A clamping connecting block 426 is fixed to the other end of the third connecting plate 418. The clamping connecting block has a fixing hole, and a clamping connecting rod 427 is set in the fixing hole. A clamping member 428 is sleeved at the end of the connecting rod. The clamping member 428 can further clamp and fix the lock during the detection process to prevent the lock plate from loosening or shifting when subjected to the detection force, ensuring the accuracy of the detection data.

[0047] The buffer limiting device includes a limiting block 430 fixed to the side of the first connecting plate 412. A hydraulic buffer 64 is installed on the limiting block 430. A stop block 429 is provided at the top of the hydraulic buffer 64 at a corresponding position on the top of the second connecting plate 415. A limit switch is provided on the outside of the hydraulic buffer 64. When the lifting cylinder 61 of the testing mechanism drives the second connecting plate 415 to rise or fall, once the second connecting plate 415 moves to its limit position, the stop block 429 will contact the hydraulic buffer 64. The hydraulic buffer 64 can effectively absorb the impact force, slow down the movement speed of the second connecting plate 415, and avoid damage to the detection component 4 due to collision. At the same time, the limit switch will transmit a signal to the PLC control device, which can promptly control the lifting cylinder 61 of the testing mechanism to stop its operation, ensuring the safety and stability of the testing device operation.

[0048] The testing process for this utility model is as follows:

[0049] 1. Select a suitable testing fixture 13 according to the specifications of the bar lock to be tested and install it on the testing station 14; adjust the position of the testing frame 3 by adjusting the fixing device 23, and install the bar lock to be tested on the testing fixture 13 and fix it.

[0050] 2. The PLC control device controls the lifting cylinder of the test mechanism to start, so that the push head of the force sensor is aligned with the lock plate to be tested, and adjusts the initial position of the clamping part to fix the lock.

[0051] 3. The PLC control device controls the electric cylinder to push, so that the force sensor is limited to 6-9N. If the locking plate can be pushed, the locking plate is qualified; otherwise, it is unqualified. After that, the electric cylinder drives the power sensor to reset, and the lifting cylinder of the testing mechanism is reset.

[0052] 4. Rotate turntable 1 to test other untested items, and repeat the above testing process.
