[0026] Platform 3, which is fixedly disposed at the bottom of the workpiece testing chamber 2;

[0027] Line clip 5, which is wound up and disposed in the operating housing 1, is used for plugging and unplugging the door lock 6 to power it on;

[0028] Insertion and removal testing assembly 7, which is fixedly disposed within the workpiece testing cavity 2, and includes a door lock insertion / removal head 8 that is vertically telescopically controlled; and

[0029] The workpiece testing chamber 2 is also equipped with an emergency unlocking device 9, and the unlocking head 10 of the emergency unlocking device 9 is located directly above the platform 3.

[0030] By installing a stage 3 in the workpiece testing chamber 2 within the operating chassis 1, the workpiece to be tested is installed in a predetermined position and then processed for testing. More specifically, the wire clip 5 is pulled out and connected to the workpiece. At this time, the insertion and removal head of the door lock 6 in the insertion and removal test assembly 7 moves up and down in the vertical direction to perform insertion and removal tests on the placed workpiece, i.e., the door lock 6. Since jamming or inability to unlock may occur during multiple insertion and removal processes, the emergency unlocking device 9 can unlock the door lock 6, thereby enabling further insertion and removal test operations, improving the stability and effectiveness of the test, and greatly enhancing the automated testing effect.

[0031] Preferably, the platform 3 is provided with a limiting groove 4 for positioning the door lock 6.

[0032] To improve the stability of the door lock 6 placed on the platform 3, a limiting groove 4 is provided on the platform 3, and the limiting groove 4 is matched with the size of the door lock 6, so that the door lock 6 can be better fixed on the platform 3 for insertion and removal test operations, thereby improving the accuracy and stability of the test.

[0033] Preferably, the insertion and removal test assembly 7 further includes a first telescopic cylinder 11 vertically fixed inside the operating housing 1, and the door lock insertion and removal head 8 is fixedly connected to the telescopic end of the first telescopic cylinder 11.

[0034] In the process of realizing the lifting and lowering insertion and removal operation of the door lock insertion and removal head 8, a first telescopic cylinder 11 is set to control the lifting and lowering of the door lock insertion and removal head 8. For example, the fixed end of the first telescopic cylinder 11 can be fixedly set on the inner wall of the operating box 1, thereby providing the power for lifting and lowering control.

[0035] Preferably, the emergency unlocking device 9 further includes a second telescopic cylinder 12, a mounting plate 13, and a rotation drive device 14. The mounting plate 13 is fixedly mounted on the telescopic end of the second telescopic cylinder 12, and the rotation drive device 14 is mounted on the mounting plate 13 and is used for the rotation control of the unlocking head 10.

[0036] By incorporating a second telescopic cylinder 12 into the emergency unlocking device 9, the mounting plate 13 is vertically raised and lowered, thereby enabling the unlocking head 10 to align with the unlocking hole on the door lock 6 for unlocking. More specifically, after aligning with the unlocking hole, the unlocking head 10 needs to be rotated. The rotation drive device 14 drives the unlocking head 10 to swing, thereby unlocking the door.

[0037] Preferably, the rotation drive device 14 includes a horizontal cylinder 15 fixedly mounted on the mounting plate 13, a drive plate 16 connected to the output end of the horizontal cylinder 15, and a connecting rod 17 oscillatingly mounted on the mounting plate 13. One end of the connecting rod 17 is hinged to the drive plate 16, and the other end of the connecting rod 17 is rotatably mounted on the mounting plate 13. The unlocking head 10 is fixed on the rotation shaft 18 between the connecting rod 17 and the mounting plate 13.

[0038] Combination Figure 2 and Figure 3 In the process of driving the unlocking head 10 to swing, the extension and retraction operation of the horizontal cylinder 15 in the rotation drive device 14 provides reciprocating driving force. Specifically, the horizontal cylinder 15 controls the reciprocating linear motion of the drive plate 16 in the horizontal direction, which drives the connecting rod 17, which is rotated on the mounting plate 13, to swing. This enables the connecting rod 17 and the rotation shaft 18 of the mounting plate 13 to swing, thereby driving the unlocking head 10 on the rotation shaft 18 to swing and unlock. It should be emphasized that the drive plate 16 and the connecting rod 17 are connected by a hinge.

[0039] Preferably, the mounting plate 13 is provided with a protective shell 19, and the protective shell 19 is provided with a rotary groove 21 for the connecting rod 20 between the drive plate 16 and the connecting rod 17 to pass through, and the connecting rod 17 is disposed inside the protective shell 19.

[0040] To achieve the linkage between the drive plate 16 and the connecting rod 17, a connecting rod 20 is provided between the drive plate 16 and the connecting rod 17. Power is transmitted through the connecting rod 20. At the same time, since the connecting rod 17 needs to swing on the horizontal plane, a protective shell 19 is provided to house the connecting rod 17 in order to improve its protective performance. Meanwhile, a rotary groove 21 is provided on the protective shell 19, through which the connecting rod 20 can swing.

[0041] Preferably, the operating housing 1 is also provided with a limiting component 22, which is provided with a third lifting cylinder 23 and a pressing plate 24. The pressing plate 24 is fixedly connected to the telescopic end of the third lifting cylinder 23 and is located directly above the platform 3.

[0042] In order to maintain the accuracy of the insertion and removal operation of the door lock 6, it is necessary to improve the stability of the door lock 6 placed and fixed on the platform 3. Therefore, a limiting component 22 is set to reinforce the positioning of the door lock 6 on the platform 3. Specifically, a third lifting cylinder 23 is set in the operating box 1 to control the vertical lifting of the pressing plate 24, thereby driving the pressing plate 24 to press the door lock 6.

[0043] Preferably, the clamping plate 24 is provided with two spaced-apart pressing heads 25, and the projection of the unlocking head 10 is between the two pressing heads 25. In actual operation, since the door lock 6 needs to be inserted and removed, the clamping plate 24 is provided with two spaced-apart pressing heads 25. While fixing the door lock 6 through the two contact points, it can also effectively reserve an area for inserting and removing the door lock 6.

[0044] The working principle and process of this utility model:

[0045] The automatic door lock testing device provided by this utility model, in use, involves installing a platform 3 in the workpiece testing chamber 2 within the operating housing 1, placing the door lock 6 on the platform 3, and then pulling out the wire clip 5 to connect with the workpiece. At this time, the door lock 6 insertion head in the insertion and removal testing assembly 7 moves up and down in the vertical direction to perform insertion and removal testing on the placed workpiece, i.e., the door lock 6. Since jamming or inability to unlock may occur during multiple insertion and removal processes, the emergency unlocking device 9 can unlock the door lock 6, thereby enabling further insertion and removal testing operations, improving the stability and effectiveness of the test, and greatly enhancing the automated testing effect.
