Description
Technical field
The invention belongs to axis products resist technology field, particularly relate to a kind of protection for axis products spindle nose and fill
Put, further relate to the using method of this protection device a kind of.
Background technology
The spindle nose machining face of axis products easily occur in colliding with when inter process transhipment and final delivery damage from
And cause product rejection, therefore need to use protection to arrange on its machined surface when axis products is in inter process transhipment or delivery
Execute, for mach axis products, mostly use the form of protection set to protect, it may be assumed that use plastic production profile and
The cylindric protection set of axis products approximation is enclosed within machining face to be protected it.In order to there be preferable protected effect simultaneously
Making what protection set can more consolidate to be fixed on product, it is right with on the spindle nose of axis products that the size at protection set beginning is done
The position answered do relatively to combine closely, but, this plastics system protection set is because the reason of plastic material, at chi
Very little slightly larger time, easily deform, peristome easily becomes oval, thus relatively difficult during the spindle nose of axis products on set.With
Time, when seasonal variations, because expanding with heat and contract with cold, protection set finish dimensional can change, summer becomes large-sized, winter size
Reducing, same protection is enclosed within summer may be more loose easy to fall off, then can compare tight difficult installation in winter.
Summary of the invention

Forming, its cross sectional shape is triangular shape.
It is a further object of the present invention to provide the using method of a kind of above-mentioned self adaptation fastening shaft head protecting device, optional
, described using method includes: the protection device described in above-mentioned any one be attached on spindle nose, tightly by the way of rotation
Gu the deformation direction of gusset is consistent；During dismounting identical with direction of rotation when installing, and rotation limit, limit extracts.
Compared with prior art, advantage is:
1), the protection device of the present invention can carry with jointing product spindle nose profile according to the configuration design of the axis products that need to protect
For effectively protection, fastening gusset can be arranged at inside the bowl portion of sleeve body, it is possible to is arranged at inside the cervical region of sleeve body,
To increase the contact surface with product spindle nose, it is used for being in close contact with product spindle nose with fixed hub body；
2), fasten gusset employing variable cross-section design, certain deformation can be produced after mounting, thus utilize the elasticity of plastic material
Make fastening gusset fit in closely on axis products, produce bigger frictional force, prevent sleeve body from transporting at axis products
Come off during vibration；
3) even if, in addition sleeve body have certain deformation or size affected by weather change time, due to fastening gusset
Use low early and high after Cross section Design, this structure also can self adaptation these change, make sleeve body all the time with product spindle nose keep
It is in close contact, and easy to installation and removal.

Detailed description of the invention
Firstly, it is necessary to explanation, self adaptation fastener shaft head protection of the present invention below will be illustrated by way of example
Device and the concrete structure of using method, feature and advantage etc., but what all of description was intended merely to illustrate, and should
It is understood as the present invention is formed any restriction.Additionally, be described by the most mentioned each embodiment or implicit appointing
Anticipate single technical characteristic, or shown or implicit any single technical characteristic in the drawings, still can be in these technology
Proceed combination in any between feature (or its equivalent) or delete, thus obtaining to be likely not to have and the most directly mention
Other embodiments more of the present invention.
Incorporated by reference to reference to Fig. 1, Fig. 2, below just come self adaptation of the present invention fastening spindle nose by this embodiment be given
Protection device is illustrative.
As it is shown in figure 1, in this embodiment, self adaptation fastening shaft head protecting device includes sleeve body 1, and this axle
Set body is configured to hollow shape, and is provided with fastening gusset 2 inside sleeve body 1.According to specifically applying needs, axle
Set body 1 inside fastening gusset 2 can arrange one or more neatly, in order to by they increase fastening gusset with
The contact area of spindle nose, thus firmly by spindle nose fixing for protection device.
Additionally, as it is shown in figure 1, be provided with in the middle part of sleeve body 1 and tighten groove 3, deform by fastening gusset and tighten groove and make
Obtain described protection device to be close on spindle nose.
Again as it is shown in figure 1, as the optional situation in the present invention, sleeve body 1 has integrated bowl portion 4 and cervical region
5, wherein the size diameter in bowl portion 4 is more than the size diameter of cervical region 5, and is provided with fastening inside described bowl portion 4 and/or cervical region 5
Gusset 2, is located at the fastening gusset 2 in bowl portion and prolongs and be axially uniformly distributed, and extend to the junction in bowl portion 4 and cervical region 5, be located at neck
The fastening gusset 2 in portion 5 prolongs and is axially uniformly distributed, and extends to tighten at groove 3.
Again as in figure 2 it is shown, as the optional situation in the present invention, fastening gusset is made by elastic plastic material, its
Cross sectional shape is triangular shape, gusset can because of install time produce elastic deformation and with need to protect product journal surface produce relatively
Big frictional force, prevents sleeve body from coming off when axis products Transport Vibration.
It addition, fastening gusset 2 uses variable cross-section shape to design, in it, envelope circular diameter is bigger straight from one from outside to inside
Footpath Dj is reduced to a less diameter Da, and diameter Dj is more than the diameter of described spindle nose, and interior envelope circular diameter can linearly contract
Little, it is also possible to reduce in convex shaped arc.Specifically, i.e. straight more than spindle nose correspondence position of the interior envelope circular diameter of forward end apex
Footpath, sleeve body 1 is prone to be inserted in；In fastening gusset 2 summit after being inserted in, envelope circular diameter is gradually reduced, and fastening gusset gradually starts
Contact with the journal surface of spindle nose, afterwards because of in it envelope dome spot diameter start the journal diameter size less than spindle nose, fastening rib
Plate 2 starts deformation.In this case, though sleeve body have certain deformation or size affected by weather change time,
Owing to fastening gusset uses low early and high after Cross section Design, this structure also can these changes of self adaptation, make sleeve body all the time with
Product spindle nose keeps being in close contact, and easy to installation and removal.
Based on above-mentioned self adaptation fastening shaft head protecting device, the present invention also provides for the user of a kind of above-mentioned protection device
Method.Specifically, this using method includes: by the way of rotation, the protection device described in above-mentioned any one is attached to axle
On head, the deformation direction of fastening gusset is consistent；During dismounting identical with direction of rotation when installing, and rotation limit, limit extracts.
Below self adaptation fastening shaft head protecting device and the using method of the present invention are elaborated the most by way of example, this
A few examples are intended for illustrating that the principle of the present invention and embodiment thereof are used, rather than limitation of the present invention, without departing from the present invention
Spirit and scope in the case of, those skilled in the art can also make various deformation and improvement.Therefore, the skill of all equivalents
Art scheme all should belong to scope of the invention and the every claim by the present invention is limited.
