PRECISE-LOCATING DRIVE END PRE-TIGHTENING DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/196741

Kind Code:

A1

Abstract:

Disclosed is a precision-locating drive end pre-tightening device, which comprises a locating platform (6), a driver (14), a capacitive sensor (4), a capacitive sensor bracket (3), a pre-tightening block (12) and a film force sensor (13), wherein a sliding groove is provided in the middle of the locating platform (6), and the pre-tightening block (12), the film force sensor (13) and the driver (14) are arranged in the sliding groove in sequence; the capacitive sensor bracket (3) is fixed to the locating platform (6), and three connecting rods (3-1) which are connected in sequence through compliant hinges are axially provided at one side of the bracket body of the capacitive sensor bracket (3); an end surface of the capacitive sensor (4) and an upper side surface of the pre-tightening block (12) are parallel to each other, and a gap exists therebetween; and a two-stage pre-tightening device for pre-tightening the pre-tightening block (12) is also provided on the locating platform (6). The technical means of the device is simple and easy, and the device can satisfy the requirements in related fields of precision locating, precision and ultra-precision machining, precision operation, precision measurement, micro-electro-mechanical systems, etc. for the precision-locating drive end pre-tightening device.
