Abstract
Device for causing epicycloid vibration, characterized in that it comprises at least one shaft secured by one of its ends to a bed connected by elastic means to the frame of the machine and furthermore supporting a thermoplastic component, the said shaft being provided at this end with a magnetic outgrowth, which when made to rotate inside a plurality of magnetic fields brought about by switching on a plurality of electromagnets located about the said shaft, generates an epicycloid-type movement of the bed, the other free end of the shaft being, on the one hand, guided in rotation within the frame of the machine and, on the other hand, driven in rotation by a motor.
Claims13
A welding apparatus for orbitally vibrating a thermoplastic component and comprising:
- a frame;
- at least one shaft having first and second ends;
- rotational driving means connected to the first end of the shaft;
- means connected to the frame and contacting the shaft to guide rotation of the shaft;
- a second end of the shaft connected to a component support bed;
- elastic means connecting the bed to the frame;
- a magnetic projection extending from an intermediate point of the shaft;
- a plurality of electromagnetic means mounted to the frame, around the shaft and extending in registry with the projection, for driving the shaft and connected bed in epicycloid motion when electromagnetic fields from the electromagnets are switched on.
