The specific position where the clamping jaw 23 of the chuck 20 and the dial 201 of the combination lock 2 are clamped is a position where the 0 scale of the dial of the combination lock 2 coincides with a standard line right above the code disc containing ring 203 of the combination lock 2 (the dial 201 and the code disc 202 are fixedly connected and can be specifically integrally formed, the code disc 202 is a rotatable movable part, and a plurality of scales are uniformly distributed along the circumferential direction, the code disc 202 is positioned in the code disc containing ring 203 and is in concentric abutting fit, the code disc containing ring 203 is a lock fixing part, and a standard line is arranged at a position of 12 points right above the circumferential direction), at this time, the main control board can send a command to a driver of the stepping motor 12 to drive the stepping motor to rotate to.
In the specific embodiment, the total scale of the rotating disc is 100, and the unlocking password is 50. Suppose that due to the internal mechanical structure of the combination lock, the unlocking mode is as follows: the dial 201 is rotated counterclockwise, and the 50 marks on the dial pass through the standard line more than five times. When the last 50 graduations align with the standard lines, the dial begins to rotate clockwise. When the dial 201 is not rotating, the lock is unlocked. When the lock is opened, the dial is rotated counterclockwise more than half a turn and the lock is reclosed.
When the device is practically used for testing the service life, the stepping motor 12 can be controlled through a program to rotate anticlockwise for 6 circles, when 50 scales are aligned with a standard line, the stepping motor 12 rotates clockwise, when a torque sensor in the chuck 20 detects that the resisting torque exceeds a certain set value (at the moment, the turntable can not rotate clockwise, and the lockset is opened), the torque sensor feeds back a signal to the main control board, and the main control board sends an instruction to a controller of the stepping motor 12 to control the stepping motor 12 to rotate anticlockwise. When the dial is rotated counterclockwise for 7 turns (rotation over half turn ensures that the combination lock is closed again, and then is rotated for 6 turns to enter the next working cycle), when the 50 graduation line is aligned with the standard line, the dial is rotated clockwise again.
In particular, if it is assumed that the lock body can be opened normally 40 ten thousand times in service life, the lock can still work normally by setting a certain opening code, for example, 50 degrees, and opening continuously 40 ten thousand times by the device of the present invention, and the test is passed.
