Abstract
Abstract In an ultrasonic welding tool of the kind comprising a relatively fixed frame, which supports an assembly including a transducer for converting electrical energy into ultrasonic vibrations, and a velocity transformer carried by the transducer for altering the amplitude of the vibrations produced by the transducer, the assembly is supported against lateral movement relative to the frame, by engaging an axially extending portion of the assembly, which is of substantially uniform cross section, as an axially sliding fit in a bearing, which is fixed relative to the frame in use, so as to support the assembly against lateral movement relative to the frame.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
An ultrasonic welding tool comprising a relatively fixed frame, an assembly including a transducer for converting electrical energy into ultrasonic vibrations, resilient means mounting the transducer on the frame, a velocity transformer carried by the transducer, the velocity transformer altering the amplitude of vibrations produced by the transducer, and being arranged to support a sonotrode shaped to engage a workpiece, and a bearing arrangement supporting the assembly against lateral movement relative to the frame, the bearing arrangement including a first part constituted by an axially extending portion of the velocity transformer, said portion being of substantially uniform cross section, and being received as an axially sliding fit in a second part of the bearing, the second part being carried by the frame and being fixed in use with respect to the frame, so that the bearing supports the said assembly against lateral movement relative to the frame.
Claim 2
Dependent Claim
147 words
An ultrasonic welding tool comprising a relatively fixed frame, an assembly including a transducer for converting electrical energy into ultrasonic vibrations, resilient means mounting the transducer on the frame, a velocity transformer carried by the transducer, the velocity transformer altering the amplitude of vibrations produced by the transducer, and being arranged to support a sonotrode shaped to engage a workpiece, and a bearing arrangement supporting the assembly against lateral movement relative to the frame, the bearing arrangement including a first part constituted by an axially extending portion of the velocity transformer, said portion being of substantially uniform cross section, and being received as an axially sliding fit in a second part of the bearing, the second part being carried by the frame and being fixed in use with respect to the frame, so that the bearing supports the said assembly against lateral movement relative to the frame.
Claim 3
Dependent Claim
26 words
A tool as claimed in claim 1 wherein said second bearing part is constituted by a sleeve, formed in a material having low energy absorbing properties.
Claim 4
Dependent Claim
16 words
A tool as claimed in claim 1 wherein said second bearing part is formed in polytetrafluoroethylene.
Claim 5
Dependent Claim
49 words
A tool as claimed in claim 1 wherein said assembly is adjustably mounted in said frame and said second bearing part is mounted in the frame in such a manner that the second bearing part can be moved so that its axis is tilted with respect to the frame.
Claim 6
Dependent Claim
19 words
A tool as claimed in claim 1 including a plurality of assemblies and bearings supported in a common frame.
Claim 7
Dependent Claim
59 words
An ultrasonic welding tool as claimed in claim 1 in which the transducer is also formed with an axially extending portion of substantially uniform cross section, said portion of the transducer being received as an axially sliding fit in a second bearing which is carried by said frame and which is fixed in use with respect to the frame.
