Embodiment 1

[0025] Such as Figure 1~4 As shown, an adjustable mechanical anti-loosening positioning device for a rotating shaft and its use method include a base 1 and a rotating shaft 3, and the feature is that: the end of the rotating shaft 3 is fixed with a flange positioning seat 2, and one side of the base 1 A fixing seat 4 is provided, and a thread sleeve 5 is arranged between the flange positioning seat 2 and the fixing seat 4. The two ends of the thread sleeve 5 are provided with threaded screw rods 6. The rod 6 is fixed on the fixing seat 4 , and the screw rod 6 at the other end is fixed on the flange positioning seat 2 . With this structure, after the rotating shaft 3 is rotated and assembled, the flange positioning seat 2 is fixed on the end of the rotating shaft 3 through a key, and the flange positioning seat 2 and the fixing seat 4 are connected by the thread sleeve 5 and the screw rod 6 at both ends, so that the flange positioning seat 2 and the fixing seat 4 can be connec...

Embodiment 2

[0034] Such as Figure 1~4 As shown, further description in conjunction with Example 1: During the processing of the base body 1, a fixed seat 4 is provided on the side where the rotating shaft 3 is installed, and after the rotating shaft 3 is assembled, the flange positioning seat 2 is installed at the end of the rotating shaft 3 through a key; Turn the wire sleeve 5 to adjust the length of the screw rod 6 at both ends, so that the screw rod 6 at one end is fixed in the hole on the side of the flange positioning seat 2 through the first fixed pile 7, and the screw rod 6 at the other end passes through the second fixed pile 8 fixed in the fixed seat 4; turn the wire sleeve 5 to shrink the screw rod 6 at both ends, so that the screw rod 6 connects the distance between the fixed flange positioning seat 2 and the fixed seat 4, thereby fixing the rotation of the rotating shaft 3; The nut 9 on the rod 6, so that the nut 9 abuts against the end of the wire sleeve 5, thereby further ...

Abstract

The invention provides an adjustable mechanical anti-loose positioning device for a rotating shaft and a using method, the adjustable mechanical anti-loose positioning device comprises a base body and the rotating shaft, a flange positioning seat is fixedly arranged at the end of the rotating shaft, a fixing seat is arranged on one side of the base body, a screw sleeve is arranged between the flange positioning seat and the fixing seat, screw rods in threaded connection are arranged at the two ends of the screw sleeve, and the screwing directions of threads at the two ends of the screw sleeve are opposite. And the screw rod at one end is fixed on the fixed seat, and the screw rod at the other end is fixed on the flange positioning seat. The flange positioning seat is fixed on the rotating shaft through a key, and a plurality of connecting holes are formed in the peripheral side of the flange positioning seat, so that the flange positioning seat and the fixed seat can be connected through the screw rods and the screw sleeves, and the screw rods at the two ends are shrunk by rotating the screw sleeves to form a pull rod structure, so that the flange positioning seat and the fixed seat can be connected and fixed, and anti-rotation fixation of the flange positioning seat is ensured; and the screw sleeve is further locked through the nut, so that the stability of the whole structure is ensured, and the fixing of the rotating shaft is more stable and firmer.

Description

technical field [0001] The invention relates to the technical field of anti-loosening positioning, in particular to an adjustable mechanical anti-loosening positioning device for a rotating shaft and a usage method. Background technique [0002] There are three common methods of mechanical anti-loosening, anti-rotation and positioning. The first is to use the cotter pin to restrain the bolt and the slotted nut after the nut is compressed. The second is to use the wire to make the screw tighten A group of screw heads constrain each other, and the third is that the rotating parts are matched with positioning pins for positioning and locking. There is a gap between the slots between the cotter pin and the slotted nut in the first type. Vibration and long-term use will reduce the pre-tightening force of the nut, and the cotter pin may break after excessive force. The second method of use is for screw installation. The arrangement has a certain direction requirement, and due to ...
