Automatic Crack Inspection for Hydro Steering Racks
by means of a Rotating System
Crack Specification : Depth : Width : Length :
50µm 80µm 3,75 mm
The steering racks are tested along the even shaft after the last surface finishing. The parts are dry and washed.
Test speed: 200mm/sec. Test rate: ca. 600 parts/hour Continuous tracing with 2 channels Blanking out of the toothed area and piston location Careful transport of the parts by means of servo drives Non-contact crack inspection, no wear oftest and rotating head Retrofitable by pattern and hardness test(eddyliner®P16 for multi-position tests)
Crack inspektion device with a view on the operating side Steel cabinet for test instrument Rotating head in maintenance position Rigth: feed and escapment of parts Middle: Rotating system Left: Sorting gate for O.K. parts and n.O.K. parts
Rotating head with precise part guiding. The driven profile rolls are adapted to the diameter of the steering racks.
A good guiding mechanism of the steering racks is achieved by the short overall length of the rotating system. Here you can see the feed of the rotating head. The connecting parts of the probes as well as the rotation monitoring and motor are clearly indicated.
