Motion’s complete Single, 3, 4 or 5 Weld Positioning Systems are designed and engineered to provide superior performance in demanding industrial automation environments. Our Dual Trunnion positioning system utilizes our high capacity “zero backlash” TMF rotary turntable for the 180° exchange which creates accuracies of 9 arc seconds and repeatability of 2-3 arc seconds. The extremely high accuracy of the TMF indexer eliminates the need of “Shot Pin” devices that are required from other manufacturers, for high accuracy on their 3-axis (H Positioner) dual trunnion weld positioners.
The DR-TR Series utilizes our TR Series servo gear heads for the dual trunnion headstocks, which allows for a 2 second, 180 degree rotation on a load of up to 4000 lbs. per side. Utilizing our TR series servo gear heads with high torque capacity, for the dual trunnion headstocks, allows for a 2.0 second 180 degree rotation on a load of up to 4000 lbs per side and 3 meters between face plates.
The TR series tailstock features a large 90 mm through hole for customers to run utilities to their tooling and fixtures. The fabricated steel structure is manufactured to be extremely rigid to handle the max loads under the fast index times on the exchange of 180 degrees and the 4000 lb per side trunnion loads.
The Multi-Axis Weld Positioning Systems provide a superior accuracy, index time, and flexibility to meet the demands of modern automation systems. As each system is built for our customer’s needs, all dimensions can be adjusted to fit the application requirement. Motion Index Drives offers nine standard models with custom central guarding and custom frame width available.
The DR-TR (H Positioner) dual trunnion weld positioning system was designed to be serviceable while tooling/fixture is mounted and in the robot cell. This eliminates the customer need to re-program robots in the cell or any of the 3-axis on the DR-TR robot positioning system. There are 9 standard models of the DR-TR (H Positioner) dual trunnion weld positioner to choose from. Each of these standard models offers an ergonomically friendly position height. Custom configurations are also available per customers’ requirements.
