Adjustable structure is set as between cantilever, the adjustable structure includes that the piston rod of one end of cantilever and the cylinder links,
Under cylinder piston rod driving can 90 ° of rotations in the horizontal plane, the other end of the cantilever utilizes the connecting rod being connected with cantilever
The length that overhanging can be adjusted is connected with axis pin, transfer block and " L " shape connecting rod in turn with the connecting rod, is fixed at figure
As on harvester holding card fix on " L " shape connecting rod, the transfer block be 90 ° of transfer blocks, utilize the adjustable structure tune
The posture of whole image collecting device realizes the angle adjustment of image collecting device in all directions, enables image collecting device
It is enough to meet position and angle requirement between mold.
The present invention is detected using fixed vision camera system, and carrying out image procossing by computer directly exports mould
The wear extent of tool, compared with the prior art, the present invention has the beneficial effect that：
1, the present invention realizes the on-line automatic of die wear amount by on-line checking, the state of wear of automatic identification mold
Detection can effectively avoid the product quality defect caused by failing to find abrasion in time.
2, the present invention is based on Machine Vision Detection die wear states greatly simplifies without dismantling mold
Detection process avoids human error.
3, criterion is intuitive, sensor is easy for installation and adapts in the monitoring of a variety of sleeving and riveting operating modes in the present invention.
4, high degree of automation of the present invention, precision is high, good operating stability.
