AI Technical Summary
When existing automobile inspection tools detect the aperture of the connection hole, the probe will form thrust on the inner side wall during the process of extending into or away from the connection hole, resulting in the position of the accessories being offset, low stability, and affecting the accuracy of the detection.
An automatic clamping mechanism for automobile inspection tools is designed, and the limit baffle and the limit seat are driven to move into the limit slot at the side end of the positioning frame through an electric push rod. While the limit seat is telescopic and retracted on the inner side of the limit slot, the clamping plates at both ends are restricted and closed to each other through the limit slot on the side of the positioning frame, thereby realizing automatic clamping of the probe and preventing position deviation caused by thrust.
It effectively improves the detection accuracy, prevents the thrust deviation when the probe extends into the inner side of the aperture, ensures that the probe is detected while stationary and fixed, and at the same time realizes the automatic clamping function of the probe.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile inspection tools, in particular to an automatic clamping mechanism for automobile inspection tools. Background Art
[0002] In the prior art, a plurality of pneumatic clamps are often arranged on the rack according to the actual size and shape of the accessory. Before inspection, the operator places the accessory on the rack. Then, the operator can input instructions through the control panel on the rack, and the clamps rotate until they are tightly against the side wall of the accessory to fix the accessory on the rack.
[0003] After the clamp fixes the accessory on the frame, the position detection mechanism and aperture detection mechanism on the frame can detect multiple parameters such as the position and aperture of the connecting holes and structures on the accessory.
[0004] However, in the actual detection process, when detecting the aperture of the connecting hole, the probe of the aperture detection mechanism needs to be inserted into the connecting hole. When the probe is inserted into the connecting hole, a thrust will be generated on the inner wall of the connecting hole during the process of the probe extending into or away from the connecting hole, which can easily cause the position of the accessory body to shift, and the stability of the accessory fixation is low, which affects the accuracy of the inspection fixture in detecting other parameters of the accessory. There is room for improvement. Utility Model Content
