Automatic Screw Fastening for M22 Threaded Tubes
A dedicated machine feeds metal tubes and threaded components, fastens them together and unloads the assembled parts. Operators replenish the feeders and start the machine.

The 30-second edit includes the machine layout, tube feeding, three consecutive fastening cycles at original speed and a view of the assembled tube.
Operators replenish the component feeder and tube rack. The machine carries out the feeding, fastening and unloading sequence after startup.
The application
Assemble a threaded component into a metal tube
The tube arrives with its M22 internal thread already prepared. This project covers assembly into that thread; drilling and tapping are separate upstream operations.
View full-size image ↗Built around the supplied parts
The customer requested automatic fastening into metal tubes. The machine combines a vibratory component feeder, tube storage, pneumatic handling and a servo-driven fastening mechanism.
The project record confirms completed production and commissioning, with the machine ready for shipment. These photographs and the workshop video document that stage.
For another part, the component geometry, thread fit, fastening depth and required inspection must be reviewed together.
Process route
From replenishment to assembled-part discharge
Automatic cycling still requires an operator to replenish both material supplies and start the machine.
Replenish and start
The operator puts threaded components into the vibratory bowl, loads tubes into the storage rack and starts the machine.
Feed and position
The feeding mechanisms present a tube and a threaded component to the fastening station.
Fasten the component
The servo-driven mechanism rotates the threaded component into the tube's existing internal thread.
Unload the assembly
The machine transfers the assembled tube to the discharge conveyor, ready for collection.
Project configuration
Dedicated feeding and servo fastening
The PLC coordinates the assembly sequence. A touchscreen provides the operator interface, and a 0.75 kW servo motor drives the fastening operation.
These specifications describe the machine shown. A different tube or threaded component needs its own feeding, locating and fastening review.
