[0045] Reference Figure 1 、 Figure 2 and Figure 4 A first driving device 7 , a second driving device 10 and a limiting device 17 are installed on the machine platform 1 .

[0046] Among them, reference Figure 1 and Figure 4 The first drive device 7 includes a first drive member 8 and a main shaft 9. The actuating end of the first drive member 8 is connected to the main shaft 9 and is suitable for driving the main shaft 9 to move back and forth along the first direction. The first drive device 7 also includes a connecting bearing 14. The connecting bearing 14 is provided with a first connecting portion 15 and a second connecting portion 16 that are rotatable relative to the axis of rotation thereof. The first connecting portion 15 is connected to the actuating end of the first drive member 8, and the second connecting portion 16 is connected to the main shaft 9 to decouple the rotation of the main shaft 9 relative to the actuating end of the first drive member 8.

[0047] The second drive device 10 is mounted on the machine 1 and includes a second drive member 11, a rack 12, and a gear 13. The gear 13 is fixedly mounted on the main shaft 9, with its axial direction parallel to the first direction. The rack 12 is slidably mounted on the machine 1 along a second direction perpendicular to the first direction and meshes with the gear 13. The actuating end of the second drive member 11 is connected to the rack 12 and is adapted to drive the rack 12 to reciprocate along the second direction, thereby driving the gear 13 to rotate about its axis. The second drive device 10 also includes a slide rail 34 and a rack 12 seat. The slide rail 34 is fixedly mounted on the machine 1 and extends along the second direction. The rack 12 seat is slidably mounted on the slide rail 34, and the rack 12 is mounted on the rack 12 seat. The second drive device 10 also includes a second connecting rod 37, which extends along the first direction and connects the actuating end of the second drive member 11 and the rack 12 seat. The actuating end of the second drive member 11 is adapted to reciprocate along the second direction.

[0048] The limiting device 17 includes a first limiting member 18 and a second limiting member 19, both of which are installed on the machine 1 and arranged on both sides of the rack 12 along the second direction; the first limiting member 18 and the second limiting member 19 are respectively provided with a first limiting portion 20 and a second limiting portion 21 suitable for moving between multiple positions along the second direction toward the rack 12, and the first limiting portion 20 and the second limiting portion 21 are suitable for limiting the movement range of the rack 12 in the second direction by abutting against the rack 12.

[0049] Specifically, refer to Figure 1 、 Figure 2 and Figure 3 A spindle 9 is provided on the machine 1 along a first direction. The left end of the spindle 9 is fixedly connected to the clamping seat 22 of the clamping device 5. The right end of the spindle 9 is connected to a first connecting rod 36 via a connecting bearing 14. The first connecting rod 36 extends along a second direction, and its other end is connected to the actuating end of the first driving member 8. The first driving member 8 can be a pneumatic cylinder or an electric cylinder, and its actuating end can be extended or retracted along the first direction. When the actuating end is extended, the spindle 9 can be driven to the right by the first connecting rod 36. When the actuating end is retracted, the spindle 9 can be driven to the left by the first connecting rod 36.

[0050] A gear 13 is fixedly mounted on the main shaft 9. The axial direction of the gear 13 is parallel to the first direction, and the axis thereof is consistent with the rotation axis of the main shaft 9. The outer periphery of the gear 13 is provided with meshing teeth, which can mesh with the rack 12 located below the gear 13 through the meshing teeth. The rack 12 is provided on a rack 12 seat, and the rack 12 seat extends along the second direction. The rack 12 also extends along the second direction. A slide rail 34 is provided below the rack 12 seat. The slide rail 34 is fixedly mounted on the machine 1, and the rack 12 seat can slide back and forth in the second direction through the slide rail 34. The front end of the rack 12 seat is also connected to a second connecting rod 37. The second connecting rod 37 extends along the first direction, and the other end thereof is connected to the actuating end of the second driving member 11. The second driving member 11 can be a pneumatic cylinder or an electric cylinder, and its actuating end can be extended or retracted in the second direction. When the actuating end is extended, the rack 12 is driven forward by the second connecting rod 37. When the actuating end is retracted, the rack 12 is driven backward by the second connecting rod 37. As the rack 12 moves forward and backward, the gear 13 rotates clockwise or counterclockwise accordingly through the meshing transmission between the rack 12 and the gear 13.

[0051] To decouple the rotation of the main shaft 9 relative to the actuating end of the first drive member 8, the aforementioned connecting bearing 14 is provided. A connecting shaft is provided between the first connecting portion 15 and the second connecting portion 16 of the connecting bearing 14. The two ends of the connecting shaft rotate and limitably connect the first connecting portion 15 and the second connecting portion 16, respectively, so that both the first connecting portion 15 and the second connecting portion 16 can rotate. The first connecting portion 15 is connected to the actuating end of the first drive member 8 via a first connecting rod 36, and the second connecting portion 16 is directly connected to the right end of the shaft 27 of the main shaft 9. When the main shaft 9 is rotated by the second drive device 10, the first connecting portion 15 can rotate relative to the second connecting portion 16 without affecting the reciprocating movement of the main shaft 9 in the first direction driven by the first drive member 8.

[0052] Reference Figure 4 The main shaft 9 includes a shaft 27 and a sleeve 28. The shaft 27 is connected to the actuating end of the first driving member 8 and is fixedly mounted on the sleeve 28. The gear 13 is fixedly mounted on the sleeve 28. The shaft 27 can be a square shaft, that is, its cross-section is square or rectangular. The inner channel of the sleeve 28 is also square, and the dimensions of the two are adapted. The shaft 27 can pass through the inner channel of the sleeve 28, and the square shape adapts to form a fixed fit between the shaft 27 and the sleeve 28. Subsequently, a mating key can be provided on the sleeve 28, and a groove can be provided on the inner surface of the gear 13. The mating key on the sleeve 28 mates with the groove on the gear 13, thereby achieving a fixed fit between the gear 13 and the sleeve 28. At this time, when the rack 12 drives the gear 13 to rotate, the gear 13 can also drive the main shaft 9 to rotate, and the clamping device 5 can then be rotated through the main shaft 9.

[0053] Therefore, according to the above-mentioned first driving device 7 and second driving device 10, the clamping device 5 can be driven to move back and forth in the first direction, thereby simulating the key 6 being inserted and removed from the key hole 6, and the clamping device 5 can also be driven to rotate, thereby simulating the key 6 rotating to unlock or lock, thereby realizing the simulation detection of the lock 3.

[0054] In addition, the setting limit device 17 also plays an important role. Figure 1 and Figure 2 The limiting device 17 includes a first limiting member 18 and a second limiting member 19, which are respectively located on the outer sides of the two ends of the rack 12 seat and can act on the rack 12 seat to limit the movement range of the rack 12 seat. Specifically, the first limiting member 18 and the second limiting member 19 can both be a cylinder or an electric cylinder, which has an actuating end that can be extended or retracted. The two actuating ends respectively form a first limiting portion 20 and a second limiting portion 21, and the first limiting portion 20 and the second limiting portion 21 respectively point to one end of the rack 12 seat. When the rack 12 seat moves to abut against the first limiting portion 20 or the second limiting portion 21, the second driving member 11 will sense that its actuating end can no longer be extended or retracted, thereby stopping further movement and changing the movement direction of its actuating end. Therefore, the movement range of the rack 12 seat can be limited by the limiting device 17. It should be noted that the second driving member 11 can determine whether it is blocked based on the magnitude of the resistance force it receives. The magnitude of this resistance force can be obtained by adjusting the driving device of the second driving member 11. This is a conventional technical means in this field and will not be described in detail here. By adjusting the position distance of the first limiting portion 20 and the second limiting portion 21 relative to the rack 12, the movement range of the rack 12 in the second direction can be adjusted, thereby adjusting the rotation angle of the clamping device 5, which can better adapt to different locks 3. At the same time, during the detection process, the position of the first limiting portion 20 and the second limiting portion 21 can be adjusted in real time, thereby changing the rotation angle of the clamping device 5 in a single detection, thereby simulating the unstable state during manual operation, and the detection result is closer to the actual operation of the user.

[0055] In addition, refer to Figure 1 and Figure 5 , also includes a positioning assembly 29, which includes a positioning seat 30, a positioning shell 31, a first positioning bearing 32 and a second positioning bearing 33; the positioning seat 30 is fixedly mounted on the machine 1, and the positioning shell 31 is fixedly connected to the positioning seat 30 and covers the gear 13; the first positioning bearing 32 and the second positioning bearing 33 are respectively located on both sides of the gear 13 along the first direction, and the inner rings of the two are fixedly mounted on the shaft sleeve 28, and the outer rings are fixedly connected to the positioning shell 31.

[0056] Specifically, there are two positioning seats 30, both of which are fixed to the machine 1 and located on both sides of the rack 12 in the first direction. Above the two positioning seats 30, a first positioning bearing 32 and a second positioning bearing 33 are provided on the sleeve 28. The inner rings of the two positioning bearings are fixed to the sleeve 28, and the outer rings are fixed to the positioning shell 31, so the rotation of the main shaft 9 will not be affected. The structure of the positioning shell 31 is shown in FIG. Figure 5 The housing 31 is a generally cylindrical member with an opening formed on its underside for the gear 13 to extend and engage with the rack 12.
