Technical Field

The invention relates to the technical field of inertia, in particular to a device for realizing any-angle locking of a transposition mechanism.

Background

The traditional indexing mechanism adopts a fluted disc for mechanical locking, the working principle is that an upper fluted disc capable of moving up and down is meshed with a static lower fluted disc to form locking, the locking position is limited by the tooth form, high-precision position precision can be provided for an inertia system, the requirement of the system on speed precision cannot be met, and the locking cannot be reliably carried out at any angle position.

Disclosure of Invention

The invention aims to provide a device for realizing the locking of any angle of a transposition mechanism, which is additionally provided with an electromagnetic locking device on the basis of the traditional transposition mechanism, can carry out electromagnetic locking at any angle and realize the measurement and calibration at any angle.

The purpose of the invention is realized as follows:

a device for realizing any angle locking of a transposition mechanism is characterized in that: the clutch comprises a main shaft, a bearing seat, a clutch stator, a clutch rotor, a bearing retainer ring, a bearing, a positioning shaft shoulder is arranged on the outer wall of the middle part of the main shaft, the bearing is sleeved on the positioning shaft shoulder at the middle part of the main shaft from left to right, the right end face of the bearing inner ring of the bearing is propped against the left end face of the positioning shaft shoulder, an annular bearing seat is sleeved outside the bearing outer ring of the bearing, the annular clutch stator is fixed on the bearing seat, the bearing retainer ring is sleeved on the outer wall of the left part of the main shaft from left to right and props against the left end face of the bearing inner ring of the bearing, the annular clutch rotor is installed on the bearing retainer ring.

The distance between the clutch stator and the clutch rotor is 0.25-2 mm.

The invention comprises a main shaft, a bearing seat, a clutch stator, a clutch rotor, a bearing retainer ring and a bearing, wherein the clutch stator and the clutch rotor on the main shaft jointly form an electromagnetic locking device. Therefore, the invention has the advantages of capability of realizing measurement and calibration of the indexing mechanism at any angle, reliable locking, reasonable design, compact structure, convenient and fast operation and the like.

Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings.

The utility model provides a realize arbitrary angle locking device of indexing mechanism, including main shaft 1, bearing frame 4, clutch stator 5, clutch rotor 6, bearing retainer ring 7, bearing 8, middle part outer wall at main shaft 1 is provided with location shaft shoulder 9, the cover has bearing 8 from a left side to the right side in location shaft shoulder 9 department at main shaft 1 middle part, the right-hand member face of bearing inner race 2 of bearing 8 pushes up at the left end face of location shaft shoulder 9, 3 overcoat at the bearing outer lane of bearing 8 have annular bearing frame 4, be fixed with annular clutch stator 5 on bearing frame 4, bearing retainer ring 7 overlaps from a left side to the right side on the left part outer wall of main shaft 1 and supports the left end face of bearing inner race 2 of bearing 8, install annular clutch rotor 6 on bearing retainer ring 7, clutch stator 5 and clutch rotor 6 position are relative.

The spacing between the clutch stator 5 and the clutch rotor 6 is 0.25-2 mm.

The working principle is as follows:

when the indexing mechanism rotates, the clutch stator 5 and the clutch rotor 6 are disengaged while maintaining a gap therebetween. When the indexing mechanism needs to be stopped, the clutch rotor 6 is attracted with the clutch stator 5 under the action of the magnetic field of the clutch stator 5. The clutch rotor 6 is held stationary with the clutch stator 5 by friction.
