The importance of product reliability.In addition to the optimization in design and material, technologic guarantee, by mechanical part chain
Structure detection is carried out in socket part position, and the defective products that there is the defects such as crackle, planform exception, matching difference is found in time, is also
One very crucial factor.However, in considerable product, the link position of mechanical part is in because of its small volume
The joint portion of multiple parts, is difficult complete observation, and quality inspection employee is being difficult to find the problem of it is present during visual detection.
It is to shoot mechanical part under the irradiation of secondary light source with a camera to shoot auxiliary detection, obtains position to be detected
Picture, and the picture of acquirement is amplified display and the enhancing of picture brightness using monitor, in order to which quality inspection employee is logical
Cross observation monitor and find and judge defect of the mechanical part in terms of structure, outward appearance.Shoot auxiliary detection and reduce workman
Detection difficulty and intensity, improve Detection accuracy, have especially for the fine defects for finding mechanical part good
Effect.
Realize that the equipment for shooting auxiliary detection generally comprises member gripper, camera, secondary light source, monitoring in the prior art
Device.Wherein screen fixture is used to grip mechanical part;Camera is erected at a certain distance from member gripper, for shooting this
Mechanical part clamped by member gripper, camera can be adjusted relative to the horizontal level and vertical range of member gripper,

Mechanical part projection illumination light;Monitor is located at the operation of detection employee, and amplification shows that the mechanical part that camera is shot is drawn
Face is watched for quality inspection employee.
But, found through practice, existing member gripper can only play a part of merely clamping mechanical part, thus shooting
Head is extremely difficult to Multi-angle omnibearing for mechanical part link position and shot, it is not easy to find to be located at the structure at shooting blind angle amount
Property defect.And shoot the operation at mechanical part link position comprehensively as far as possible by adjusting the position and direction of video camera very
Trouble, not enough, industrial video camera is again heavier for flexibility ratio, it is easy to which being in course of adjustment the accident such as falls off and cause to damage
Lose.
