Abstract
A kind of support nested structure of cantilever reel spindle nose, axial direction along supporting sleeve is provided with groove, the width of the groove 4 8mm bigger than the diameter of bolt head, depth is the axial line position of the corresponding supporting sleeve of center line of spindle nose upper bolt hole, along supporting sleeve radially-inwardly processing bolt head radius size add 2 5mm, groove length be the length of supporting sleeve or be bolt total length add 10 30mm.Its advantage is that the improvement by processing U-shaped groove to spindle nose supporting sleeve, can directly dismount bolt using allen wrench, save the time, improve overhaul efficiency.
Description
Technical field
The utility model is related to the support nested structures of Strip cantilever reel spindle nose, more particularly to a kind of to be suitable for uncoiler
With the support nested structure of the cantilever reel spindle nose of coiling machine.
Background technology
Traditional coiler mandrel axis and spindle nose are separate types, and spindle nose is fixed on the end of spool shaft with 8 hexagon socket head cap screws
On face, because the reference diameter of fixed bolt hole on the spindle nose of design is close with the supporting sleeve outside diameter of spindle nose, in assembly,
First spindle nose must be installed in spool shaft, then on bearing and the integral rear integral installation to spindle nose of supporting sleeve assembly.Once
When spindle nose bolt looseness, bearing break down or regular dismounting drum fan-shaped plate are needed to safeguard, it is necessary to which first welding draws horse branch
Support set and bearing are integrally pulled up, then dismantle the fixing bolt of spindle nose, and time-consuming too long, overhaul efficiency is low, seriously affects the life of unit
Production.
Utility model content
The purpose of this utility model, which is just to provide one kind, directly to be dismounted bolt using allen wrench, save
Time, improve the support nested structure of the cantilever reel spindle nose of overhaul efficiency.
The solution of the utility model is such：
A kind of support nested structure of cantilever reel spindle nose is provided with groove, the width ratio of the groove along the axial direction of supporting sleeve
The big 4-8mm of diameter of bolt head, depth is the axial line position of the corresponding supporting sleeve of center line of spindle nose upper bolt hole, along support
The radius size of the radially-inwardly processing bolt head of set adds 2-5mm.
More specific technical solution further includes：The groove length is the length of supporting sleeve or is that the total length of bolt adds
Upper 10-30mm.
Further：The groove is U-shaped groove.
The utility model has the advantages that the improvement by processing U-shaped groove to spindle nose supporting sleeve, can directly use interior six
Angle spanner dismounts bolt, saves the time, improves overhaul efficiency.
Description of the drawings
The structural schematic diagram of Fig. 1 the utility model supporting sleeve 1.
Fig. 2 is the A-A sectional views of Fig. 1.
Fig. 3 is the assembling schematic diagram of supporting sleeve 1 and spindle nose.
Specific implementation mode
The present embodiment is considered simultaneously according to the overall length dimension of the hexagon socket head cap screw head outer diameter and bolt of fixed spindle nose
The annular thickness of supporting sleeve, two positions of processing are opposite in the outer circle of spindle nose supporting sleeve, and width can be such that bolt head passes through,
Axial length can make bolt take out U-shaped groove, can be fastened in the case where not pulling up supporting sleeve loosening bolt or
Demounting bolt.
As shown in Figure 1, 2, the axial direction along supporting sleeve 1 is driveed there are two the opposite groove 2 in position, according in fixed spindle nose six
The overall length dimension of corner bolt head outer diameter and bolt, the width for designing groove 2 is bigger 4-8mm than the diameter of bolt head, depth（D-
T）/ 2 be the axial line position of the corresponding supporting sleeve of center line of spindle nose upper bolt hole, along the radially-inwardly processing bolt of supporting sleeve
The radius size of head adds 2-5mm, and when the total length of bolt is more than the length of supporting sleeve, the length L of design U-shaped groove is support
The length of set；When the total length of bolt is less than the length of supporting sleeve 1, the length L of design groove 2 adds for the total length of bolt
10-30mm, convenient for the allen wrench that can set aside concerns under being in tightening state in bolt, groove 2 is U-shaped groove.
Specific example is as follows：
The opposite U-shaped groove 2 in two positions is processed in the outer circle of supporting sleeve 1, according to connection spool shaft 4 and spindle nose 3
The head diameter φ 45mm of the hexagon socket head cap screw 5 and total length 345mm of bolt, the width b of U-shaped groove 2 are designed as 50mm, because of branch
The length of support set 1 is 200mm, and 2 length L of design U-shaped groove is 200mm, convenient for taking out bolt, the depth of U-shaped groove 2（D-T）/
2 are designed as 25mm.
The course of work of the present embodiment：When spindle nose bolt looseness, directly spiral shell can be fastened with corresponding allen wrench
Bolt；It, can after the safety measure for carrying out maintenance when bearing breaks down or regular dismounting drum fan-shaped plate is needed to safeguard
Directly Bolt dismantling is taken out with allen wrench, online spindle nose is hung out later from spool shaft, while replaced with standby
Spindle nose.It draws horse to pull up entire supporting sleeve without welding again, saves the repair time, improve overhaul efficiency.
