Document Type and Number:
WIPO Patent Application WO/2023/105630
Kind Code:
A1
Abstract:
[Problem] To, in relation to a gripping device 1, broaden the dimensional range of objects that can be gripped by one gripping part and precisely machined. [Solution] This gripping device 1 comprises a gripping spring 2 that is described below, the gripping spring 2 gripping an object due to drive force generated by a prescribed drive source. Specifically, the gripping spring 2 is a coil spring and is reduced in diameter due to the drive force, whereby the inner periphery of the gripping spring 2 comes into contact with the outer-side surface of the object and grips the object. This makes it possible to employ a gripping spring 2 such as is described above as a gripping part, thereby making it possible to broaden the dimensional range of objects that can be gripped by one gripping part and precisely machined.
