Abstract
The utility model discloses a kind of tools for preventing elastic washer piston ring, belong to assembling process technique field, the device is the tool for improving nut assembly, the problem of being able to solve elastic washer assembling process " piston ring ", sleeve 1 accommodates nut front end and increases unthreaded hole, and unthreaded hole diameter is greater than elastic washer overall diameter；Length is greater than or equal to the thickness S of elastic washer 4；Assembling process can limit elastic washer and " piston ring " occurs.
Description
Technical field
The utility model belongs to assembling process technique field, is related to the sleeve more particularly to one of tightening axle assembly nut
The sleeve barrel tool of kind and elastic washer cooperation assembly, or perhaps it is related to elastic washer assembly tool.
Background technique
At present buying or homemade tightening axle with assembly nut tool, a usually hexagon ring sleeve, leading inside without
Chamfering contains 120 ° of chamferings, and when being assembled using such sleeve, the elastic washer being used cooperatively with nut is revolved in nut
Into in the process, when have " piston ring " phenomenon, it may be assumed that elastic washer opening n value becomes larger, and washer is caused to be scrapped.In order to solve
This problem, people are usually to improve from nut size, elastomeric gasket material etc., by changing nut end face chamfering or replacement
Elastomeric gasket material etc. cannot prevent completely though reducing the generation of problem to a certain extent.
Utility model content
The technical issues of the utility model solves is to provide a kind of tool for preventing elastic washer piston ring, i.e. one kind is tightened
The axis sleeve for tightening (assembly) nut is the structure for improving nut setting tool, solves elastic washer assembling process " piston ring "
The problem of.
The technical solution of the utility model includes: a kind of tool for preventing elastic washer piston ring, sleeve, which has to accommodate, to be filled
Hole with nut accommodates the front end in the hole of assembled nut until the end of sleeve has unthreaded hole, and unthreaded hole diameter, which is greater than, to be assembled
Elastic washer diameter；Accommodate thickness and elastic cushion that the sum of the hole of assembled nut and the height of unthreaded hole are greater than or equal to nut
The sum of thickness after the pressing of circle.
A kind of tool preventing elastic washer piston ring, sleeve have hexagon ring, and the front end of sleeve hexagon ring is until sleeve
End has unthreaded hole, and unthreaded hole diameter is greater than assembled elastic washer diameter；The sum of hexagon ring and the height of unthreaded hole are greater than or wait
The sum of thickness after the pressing of the thickness and elastic washer of nut；Hexagon ring can accommodate assembled nut.
Preferably, the front end of sleeve hexagon ring has chamfering, increases by a Duan Guangkong forward in the chamfering of hexagon ring sleeve.
Preferably, the height of unthreaded hole is greater than or equal to the thickness after elastic washer flattens.
Preferably, unthreaded hole has taper, and the diameter of front end is greater than the diameter of rear end.
Preferably, washer is included among sleeve.
Preferably, sleeve has hexagon ring leading inside without chamfering or contains 120 ° of chamferings.
Preferably, the sleeve is for tightening axle assembly nut.
The working principle of the utility model is: " piston ring " occurs for elastic washer, it is that it receives external force and has been more than its material
The flexible deformation of material.One Duan Guangkong of (preceding) increase in hexagon ring sleeve chamfering, aperture are greater than elastic washer diameter.In this way, working as
When nut precession, for the external force that elastic washer is subject to once increasing, unthreaded hole can produce radial reaction force, balance elastic washer
Stress and limit the deformation of washer.Sleeve end face increases unthreaded hole, for balancing simultaneously elastic washer external force and restrained deformation.Increase
Hub internal bore length, is contained within elastic washer among hub internal bore.
The utility model has the beneficial effects that
Using this structural sleeve, solves the problems, such as that elastic washer assembling process is recurrent " piston ring ", reduce because of work
Part scraps, dismantle do over again caused by waste, improve work efficiency.This structure is equally applicable to bolt assembly.
Detailed description of the invention
The structural schematic diagram when use of the sleeve 1 of Fig. 1 the utility model.
The main view direction cross-sectional view of Fig. 2 the utility model sleeve 1.
The top view of Fig. 3 the utility model sleeve 1.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
The utility model is a kind of for preventing the sleeve of elastic washer piston ring, including the sleeve with hexagon ring, sleeve six
Increase the unthreaded hole of certain length in the front end of corner apertures, unthreaded hole diameter is greater than elastic washer diameter, can increase original sleeve simultaneously
Length.
Fig. 1 is the structural schematic diagram that nut process is assembled using the sleeve 1 of the utility model, and nut 3 is tightened with screw rod 2
When, elastic washer 4 is contained in the unthreaded hole of sleeve 1；
N is the opening value of elastic washer 4, and D is the diameter of elastic washer 4, and e is the internal diameter of unthreaded hole；The utility model changes
Device can improve in original ut socket structure, specifically:
1. 1 front end of sleeve increases unthreaded hole, diameter is greater than 4 overall diameter of elastic washer；Highly (length) size is greater than or equal to
Thickness s after elastic washer 4 flattens；This unthreaded hole can have certain taper (i.e. horn mouth), reduce sleeve in diagram s length
Frictional resistance when exiting.
2. 1 inner hole of sleeve has certain length, height dimension are as follows: be greater than or equal to 3 thickness m of nut and elastic washer 4 is thick
The sum of s is spent, washer 4 can be included among sleeve 1 by assembling process.
For the sleeve (tool) for tightening axle assembly nut, it is equally applicable to the assembly of bolt.
