Connecting rod cracking machine

Challenger

The manufactured machine is capable of processing 3 different conrod models with a minimum changeover time between batches (less than 15 minutes).

The challenge on the project consisted in integrating those references on the same machine, since the size, geometry and characteristics of those are very diverse.

The operation consists of a semi-automatic process, on which an operator loads/unloads the connecting rods as well as pre-loads the screws to the feeder.

OPERATIONS

Scribing

Generation of the breakage initial groove, using a fiber laser and controlling the depth of the operation depending on the part variant to work with.

OPERATIONS

Cracking

Breakage of connecting rods for subsequent assembly, performed on a standard Gaindu Cracking concept, performed by a proprietary electrically driven cracking technology, patented by Gaindu. This technology allows the complete removal of all the hydraulics from the machine, with huge benefits in terms of cleanliness and environment.

OPERATIONS

Assembly

The cracking and assembly machine includes the operation of tightening back the cap and the body. The components are fed by a semi-automatic feeder where we control the type and orientation prior to assembly. All the tightening process performs controlling the torque and angle applied.

Tightening

02/02

Possibility to perform tightening operations using electrical screwdrivers, controlling the applied torque and final angle on the process.
Simpler tightening / untightening operations could also include pneumatically driven tighteners or tailor made untightening electromechanical units.
We adapt our assembly solutions to our customer's need, integrating on that purpose their preferred electrical screwdriver brand.
Union of components using all type and sizes of bolts, screws, thread plugs, etc…

When the conditions of the production line or the floor space available are restricted, there is the possibility of integrating vision equipment to perform various part testing tasks:

Real-time checking of boring or machining operations on the workpiece.
Dimensional control of the machined parts.
Component identification in terms of diversity and positioning.
Angular or axial components orientation prior to assembly.
The vision system is carefully studied in each case, analyzing lighting requirements and ambient conditions to ensure a reliable and repeatable process.

Feeding

When it comes to automating processes, automatic component feeding is a fundamental aspect of the cell's autonomy.
There are several alternatives on the market to automatically feed parts to be assembled. At Gaindu we analyze each case individually to offer the best alternative, taking into account key aspects such as speed, part protection or required orientation.
Among the alternatives we work with, we make our own design feeders by means of vertical warehouses as well as bowl-feeder or step-feeder integrations, which we customize for each application.
