Abstract
A kind of support nested structure of cantilever reel spindle nose, groove is provided with along the axial direction of support set, the width of the groove 4 8mm bigger than the diameter of bolt head, depth is the axial line position of support set corresponding to the center line of spindle nose upper bolt hole, 2 5mm are added along the radius size of the radially-inwardly processing bolt head of support set, and groove length is the length of support set or is that the total length of bolt adds 10 30mm.Its advantage is the improvement by processing U-shaped groove to spindle nose support set, directly bolt can be dismounted using inner hexagon spanner, save the time, improve overhaul efficiency.
Description
Technical field
It is more particularly to a kind of to be applied to uncoiler and volume the present invention relates to the support nested structure of Strip cantilever reel spindle nose
Take the support nested structure of the cantilever reel spindle nose of machine.
Background technology
Traditional coiler mandrel axle 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 and the support set outside diameter of spindle nose are close, in assembling,
First spindle nose must be installed in spool shaft, then bearing and support set are assembled integral rear integral installation to spindle nose.Once
When spindle nose bolt looseness, bearing break down or need the regular dismounting drum fan-shaped plate 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 oversize, overhaul efficiency is low, has a strong impact on the life of unit
Production.
The content of the invention
It is an object of the invention to provide one kind directly to be dismounted using inner hexagon spanner to bolt, when saving
Between, improve the support nested structure of the cantilever reel spindle nose of overhaul efficiency.
The solution of the present invention is such：
A kind of support nested structure of cantilever reel spindle nose, groove is provided with along the axial direction of support set, the width of the groove compares bolt
The big 4-8mm of diameter of head, depth is the axial line position of support set corresponding to the center line of spindle nose upper bolt hole, along support set
Radially-inwardly the radius size of processing bolt head adds 2-5mm.
More specifically technical scheme also includes：The groove length is the length of support set or is that the total length of bolt adds
Upper 10-30mm.
Further：Described groove is U-shaped groove.
It is an advantage of the invention that the improvement by processing U-shaped groove to spindle nose support set, directly can be pulled using interior hexagonal
Hand dismounts to bolt, saves the time, improves overhaul efficiency.
Brief description of the drawings
The structural representation of Fig. 1 support sets 1 of the present invention.
Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is the assembling schematic diagram of support set 1 and spindle nose.
Embodiment
The present embodiment is the overall length dimension of the hexagon socket head cap screw head outer diameter and bolt according to fixed spindle nose, is considered simultaneously
The annular thickness of support set, spindle nose support set it is cylindrical on process two positions it is relative, width can make bolt head by,
Axial length can make bolt take out U-shaped groove, can be fastened in the case where not pulling up support set loosening bolt or
Demounting bolt.
As shown in Figure 1, 2, two relative grooves in position 2 are provided with along the axial direction of support set 1, according in fixed spindle nose six
The overall length dimension of corner bolt head outer diameter and bolt, the width of design groove 2 is bigger 4-8mm than the diameter of bolt head, depth（D-
T）/ 2 be the axial line position of support set corresponding to the center line of spindle nose upper bolt hole, along the radially-inwardly processing bolt of support set
The radius size of head adds 2-5mm, and when the total length of bolt is more than the length of support set, 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 support set 1, the length L of design groove 2 adds for the total length of bolt
10-30mm, is easy to the inner hexagon spanner that can be set aside concerns in the case where bolt is in tightening state, and groove 2 is U-shaped groove.
Specific example is as follows：
Support set 1 it is cylindrical on process the relative U-shaped groove 2 in two positions, according to connection spool shaft 4 and in spindle nose 3 six
The head diameter φ 45mm of the corner bolt 5 and total length 345mm of bolt, the width b of U-shaped groove 2 is designed as 50mm, because of support set
1 length is 200mm, and the length L of design U-shaped groove 2 is 200mm, is easy to take out bolt, the depth of U-shaped groove 2（D-T）/ 2 set
It is calculated as 25mm.
The course of work of the present embodiment：When spindle nose bolt looseness, spiral shell directly can be fastened with corresponding inner hexagon spanner
Bolt；, can after the safety measure for carrying out maintenance when bearing breaks down or needs regular dismounting drum fan-shaped plate to safeguard
So that directly Bolt dismantling is taken out with inner hexagon spanner, online spindle nose is hung out from spool shaft afterwards, while replaced with standby
Spindle nose.Draw horse to pull up whole support set without welding again, save the repair time, improve overhaul efficiency.
