Dimac mcv 100% inspection and sorting machines are equipped with stations for the mechanical detection of internal sockets and shaped recesses. This is possible by switching the rotary table mode from continuous to indexed and enabling the available socket or cavity inspection station.
The station features penetration units above and below the rotary table with collets for the insertion of interchangeable screwdrivers or calibration pins. The depth of penetration is targeted by a high resolution digital camera with an accuracy of less than 0.1mm.
Torx or hex sockets and any other recesses can be mechanically inspected for internal depth, step height (rivet and inserts), broken lobes, excess of surface treatment, centricity.
The mechanical inspection can be performed either on the head of the screw from above the rotary table or on the opposite end at the bottom of the shank under the rotary table. The penetration stroke can reach up to 30 mm in the Dimac mcv3 model and bits up to Torx 100 can be used.
Mechanical tests of Torx and Hex sockets can be performed up to 200 pcs / min –
This mechanical test station can be enabled or disabled depending on the required inspection criteria and it makes the Dimac mcv inspection machines absolutely flexible to perform any type of inspection.
In 2022 this station was upgraded to perform high-precision measurements of internal shapes cylindrical or conical shapes in turned bushings. The penetration cycle is carried out with a telescopic gauge designed to penetrate the conical hole of the bushing in two passes from under the rotary table, while a high resolution camera measures the depth of penetration reached by the gauge for each step.
