Weight-Correction Machines for Connecting-Rods
100 FBMP | 200 FBMP | 100 RBMP

Range of application
Measurement of the weight of rotating and oscillating parts or the absolute weight of machined connecting-rods for internal combustion engines. Controlled weight correction at the prepared correction pads at the small-end and big-end. Weight correction is usually followed by fine-boring.

Application of the machine in large-volume series production, interfaced with the production line.

Design
Two-station machine with automatic operating sequence.

Modular machine design, thus optimally adaptable to the task. Arrangement of the stations directly adjacent to each other. Loading by hand, transfer of the connecting-rod in the machine by positioning device or exchange transporter. Welded machine base for accommodation of the units, prepared for removal of the chips by a slide chute. Electromechanical, numerically controlled milling unit and digitally operating tandem weighers. Microprocessor-controlled measuring equipment for acquisition of the measured values and processing: SPS machine control with fault diagnsis.

Example of combining both stations by handling unit type RBMP. Linking by robot, linear or surface loader portal is also possible.

Correction station with digitally-controlled, electro-mechanical slide units. Milling of the correction pads with amply dimensioned face milling cutters. Hard-metal carbide inserts with divided arrangement for overlapping cut. The horizontal layout of the units allows easy chip removal directly through the machine bed into a collection bin, or on an optional chip-conveyor. Depending on the design of the connecting-rod, and the number of correction pads, either one or two milling units and a loading carriage can be used. The clamping device operates with direct force flow.

Measurement and check weighers each with two electronic load-cells for the big-end and small-end. Digital determination of absolute weight or deviation from pre-defined target weight. Zero setting according to a master connecting-rod. Weigher adaptable to other work-piece types by adjustment or exchange of the adapter.
