The buffer assembly 5 may be a compression spring or a rubber block, and the buffer assembly 5 may be disposed between the locking member 41 and the driving member 42, so that when the locking member 41 is unlocked from the first guide rail 1, the locking member 41 and the connecting member 43 may rapidly return to an initial state under the elastic restoring force and self gravity of the buffer assembly 5, so that the sliding assembly 3 may continue to slide along the first guide rail 1 and the second guide rail 2.
As another embodiment, the locking member 41 abuts against the outer wall of the first sliding portion 31, and the driving member 42 is mounted on the outer wall of the second sliding portion 32 and is in contact connection with the locking member 41. That is, the first sliding portion 31, the locking member 41, the driving member 42 and the second sliding portion 32 are sequentially connected from top to bottom, and when the driving member 42 applies a vertical upward force to the first sliding portion 31 through the locking member 41, the first sliding portion 31 is pushed up against the first rail 1 when receiving the force of the locking member 41 because the first sliding portion 31 is not in full contact with the first rail 1, thereby completing locking.
The clamping device comprises the locking structure, the first guide rail 1 and the second guide rail 2 are arranged on a fixing frame 6 in parallel, the fixing frame 6 is a mounting base, the mounting base is reserved with a mounting space of the first guide rail 1 and the second guide rail 2, and the first guide rail 1 is fixed on the mounting base through a fixing piece 7. The sliding component 3 is provided with a clamping component, the clamping component is a mechanical arm or a clamping plate, the PCB is clamped in the clamping component, and each side of the PCB is provided with at least two clamping devices. The sliding component 3 drives the clamping component to slide along the first guide rail 1 and the second guide rail 2 under the action of driving force, or is locked with the first guide rail 1 under the action of the locking component 4. Therefore, for the PCB with different sizes, the distance between the two clamping devices can be changed only by adjusting the position of the sliding component 3, so that the PCB with different sizes can be fixed by the clamping component and can be fixed at any position of the guide rail.
A wire needle testing machine comprises the clamping device. When the detected PCB is fixed at a preset position, detection operation can be performed, and the accuracy of detection is improved because the PCB is fixed firmly.
