Torque Drivers
Givens Machine Systems provides solutions to improve your operations by using self positioning, custom fastening systems. Tools like torque drivers are necessary in every production environment to quickly tighten fasteners and to ensure the correct torque spec is achieved.
We can design a custom system that locates the tooling to your product, aligns multiple nut runners, and fastens multiple torque points simultaneously to optimize production. These systems can be controlled via air logic, or via PLC controls and DC torque tools or pneumatic torque tools can be integrated into these systems.
Improve Manufacturing Operations
By investing in custom fastening systems from Givens Machine Systems, you can;
- Reduce labour costs (one operator running multiple tools)
- Improve ergonomics (operator controls can be kept at an ergonomic height while the tool is above the shoulders or below the waist)
- Improved cycle time (multiple fasteners installed simultaneously)
- Improved repeatability (tooling aligns to the part or fixture, increasing position repeatability)
Enhance Production with Custom Fastening Torque Tools
PLC controls can integrate many poke yokes such as target torque, fastener detection, misalignment detection, reverse function lockout, and vision inspection.
Using DC torque tools with torque controllers enables the ability to create a torque strategy, which monitors rundown angles and final angles to ensure a perfect torque is achieved each time. If the rundown angle does not reach its target before the set torque is reached, this could be an indicator of a damaged bolt.
Past Projects
Fender Install Tool
For these custom fender install tools (one for each side of the car), we used all pneumatic logic and controls to keep these tools low cost, simple and lightweight.
The operator would begin by loading the fender and nuts into the fixture by hand. They would then use the guide pins on the tool to line up the fender with the side of the car body. Once located, the operator triggered the clamps using buttons on the handlebar to clamp the fixture to the car. In the next step, the operator pressed another set of buttons and the torque tools moved into position, using air cylinders, and fastened and torqued the nuts. The torque wrench would produce a good torque signal, telling the operator that the install was successful and that it was okay to release the tool from the car and prepare the next fender for another vehicle.
Rear Hatch Fastening Tool
For this custom nut runner tool, we used an overhead crane so the tool could follow the car along the assembly line for some distance. To align the tool to the car, rods locate at the bottom of the tool inserted into some holes in the car body. Once in place, arms on the top of the tool moved down to lock in its position on the car.
When the operator got confirmation from the PLC that the tool was correctly fixtured, they would be allowed to press a set of buttons that extended the four nut runners outward and then upward to fasten and torque the nuts for the hatch hinges. The PLC would make sure that the correct torque was achieved on all four nuts and then store the data for quality tracking purposes. The operator was then allowed to unclasp and remove the tool from the vehicle.
In this demonstration, the custom-designed torque tool approaches the rear of a vehicle body and aligns itself to the vehicle. The four DC torque spindles are inserted through the rear window opening and expand to reach the bolts. All four bolts are torqued simultaneously before retracting the tooling.
