Abstract

The invention belongs to mechanical manufacturing engineering fields, are related to a kind of lock washer with double ears and its method for dismounting.When being dismantled for traditional lock washer with double ears, because chisel directly taps stop washer lock point position is bonded with bolt seamed edge, the problem of being also easy to produce cutting metal clast, design a kind of lock washer with double ears, compared with Conventional binaural stop washer, ring part, no changes have been made for lock portion, and Main change is to lock nose part, and new lock nose part is in original rectangle plane centre position added with a pyramid type groove.When dismantling stop washer, first tapered punching pin head is inserted into the groove among stop washer lock nose part and bolt seamed edge binding face, tapered punching pin tail portion is tapped again, make the tapered punching pin head further binding face of embedded lock nose part and bolt seamed edge, then with the lock nose part of the direction bending stop washer far from bolt, it is kept completely separate the lock nose part of bolt seamed edge and stop washer, it is achieved thereby that the releasing of screw retention state.

Description

A kind of lock washer with double ears and its method for dismounting
Technical field
The invention belongs to mechanical manufacturing engineering fields, are related to a kind of lock washer with double ears and its method for dismounting.
Background technology
Lock washer with double ears loosens design because its is easy to operate, locking reliably, manufacture is of low cost in threaded connector Upper extensive use.Lock washer with double ears assemble when by lock tail (long end lock ear) bending or against installation side, lock point (short end lock Ear) against hexagon-headed bolt seamed edge carry out locking fixation, when dismounting, then relies primarily on chisel and taps stop washer lock point and bolt The fitting position of seamed edge detaches the two, so as to release the locking state of bolt.But in actual mechanical process, because of chisel Impact direction is difficult to completely the same with lock point and the direction that is bonded of bolt seamed edge, bolt seamed edge is caused to be cut or cut wound, and cut It cuts or when cut wound position is often accompanied by metal fragment and falls.For the cavity more demanding to cleannes such as bearing bore, gear cavity, tear open Generated cutting metal clast during stop washer is unloaded, is not only difficult to clean off, more directly affects the high speeds rotating member such as bearing, gear Operation stability, the safety that will directly affect machinery equipment when serious.
Invention content
The purpose of the present invention is:A kind of lock washer with double ears and its method for dismounting are provided, ensured when stop washer is dismantled, Especially bearing bore, gear cavity do not use traditional when being dismantled to the more demanding inside cavity stop washer of cleannes It taps lock point and the mode of the binding face of bolt seamed edge is decomposed, so as to avoid the generation of various cutting metal clasts, ensure The cleannes of inside cavity.
The technical scheme is that:
A kind of lock washer with double ears, compared with Conventional binaural stop washer, ring part (1a), lock portion (1b) equal nothing Change, Main change is to lock nose part (1c), and original nose part (1c) of locking is a rectangle plane, new lock nose part (1c) In original rectangle plane centre position added with a pyramid type groove, the big end of groove is located at lock nose part (1c) outer ledge, The small end of groove is close to ring part (1a).
A kind of lock washer with double ears method for dismounting:
When dismantling stop washer (1), stop washer (1) first is inserted on tapered punching pin (2) head and locks nose part (1c) and spiral shell In groove among bolt seamed edge binding face, then tapered punching pin (2) tail portion is tapped, make tapered punching pin (2) head further embedded lock The binding face of nose part (1c) and bolt seamed edge, then with the lock nose part of the direction bending stop washer (1) far from bolt (1c) is kept completely separate bolt seamed edge and the lock nose part (1c) of stop washer (1), it is achieved thereby that the solution of screw retention state It removes.

Specific embodiment
The present invention is explained in further detail below.Referring to figure
A kind of lock washer with double ears, it is characterised in that:Compared with Conventional binaural stop washer, ring part (1a), lock tail Partly (1b) no changes have been made, Main change is to lock nose part (1c), and original lock nose part (1c) is a rectangle plane, new Nose part (1c) is locked in original rectangle plane centre position added with a pyramid type groove, and the big end of groove is located at lock nose part (1c) outer ledge, the small end of groove is close to ring part (1a).
The present invention application method be:
When dismantling stop washer (1), stop washer (1) first is inserted on tapered punching pin (2) head and locks nose part (1c) and spiral shell In groove among bolt seamed edge binding face, then tapered punching pin (2) tail portion is tapped, make tapered punching pin (2) head further embedded lock The binding face of nose part (1c) and bolt seamed edge, then with the lock nose part of the direction bending stop washer (1) far from bolt (1c) is kept completely separate bolt seamed edge and the lock nose part (1c) of stop washer (1), it is achieved thereby that the solution of screw retention state It removes.

Claims (2)

1. a kind of lock washer with double ears is made of ring part (1a), lock portion (1b), lock nose part (1c), feature exists In:For the lock nose part (1c) in rectangle plane centre position added with a pyramid type groove, the big end of groove is located at lock nose part (1c) outer ledge, the small end of groove is close to ring part (1a).
2. a kind of method for dismounting of lock washer with double ears, it is characterised in that:Stop washer first is inserted on tapered punching pin (2) head (1) it locks in the groove among nose part (1c) and bolt seamed edge binding face, then taps tapered punching pin (2) tail portion, make tapered punching pin (2) head is further embedded in the binding face of lock nose part (1c) and bolt seamed edge, then with the direction bending stop far from bolt The lock nose part (1c) of washer (1) is kept completely separate bolt seamed edge and the lock nose part (1c) of stop washer (1), so as to fulfill The releasing of screw retention state.
