The amendment such as row plating or compensation polishing, and the time that processing is electroplated is longer, while the electroplated layer after being electroplated is easy to fall off, and
And machinery equipment can not work in the process, to affect working efficiency.
Utility model content
In order to solve the above technical problems, the utility model provides and a kind of modified has after wearing without be electroplated
The RG main shaft of lower concentricity difference.
To achieve the above object, the technical solution adopted in the utility model is a kind of RG master with lower concentricity difference
Axis, including main shaft body, main shaft body are equipped with feed appliance and are set with end, and structural feature is that the feed appliance is set with end
End face is equipped with axially extending taper hole, the tapped blind hole for being connected with coaxial arrangement of taper hole, and feed appliance is set with end and is equipped with annular
Array and axially extending strip gab is carried out by end face, strip gab is connected to tapped blind hole, can in the taper hole
Dismantling connection has the cone block being axially movable.
Bore as a further improvement of the utility model, block the area of section is identical as the area of section of taper hole and and taper hole
It is fitted close.
Cone block is equipped with the locking hole being arranged with central axis coaxial, locking as a further improvement of the utility model,
The clamping screw with tapped blind hole cooperation is inserted in hole.
Excessive inclined-plane is equipped between taper hole and tapped blind hole as a further improvement of the utility model,.
It compares with the prior art, the beneficial effects of the utility model are: design is rationally, structure is simple, when sending for main shaft
After glassware suit end is worn, it is not necessary that the time-consuming more long and complicated processing such as processing is electroplated, clamping screw only need to be gently turned
Feed appliance suit end can be made to be fitted closely with feed appliance, thus while improving the concentricity of feed appliance and main shaft,
The working efficiency of machinery equipment can also be improved.
Detailed description of the invention
Fig. 1 is that the feed appliance of the utility model is set with end structure schematic diagram
Fig. 2 is the schematic diagram of the section structure of the embodiments of the present invention one；
Fig. 3 is the schematic diagram of the section structure of the embodiments of the present invention two；
Wherein, 1- main shaft body, 2- feed appliance are set with end, 3- taper hole, 4- tapped blind hole, 5- strip gab, 6- cone block, 7-
Locking hole, 8- clamping screw, the excessive inclined-plane 9-.
Specific embodiment
Explanation is further explained to the utility model in the following with reference to the drawings and specific embodiments, but is not limited practical
Novel protection scope.
Embodiment one, as depicted in figs. 1 and 2, a kind of RG main shaft with lower concentricity difference, including main shaft body 1, it is main
Shaft body 1 is equipped with feed appliance and is set with end 2, and the end face at the feed appliance suit end 2 is equipped with axially extending taper hole 3, cone
The tapped blind hole 4 for being connected with coaxial arrangement in hole 3, feed appliance are set with end 2 and are equipped with annular array and carry out by end face axial
The strip gab 5 of extension, strip gab 5 are connected to tapped blind hole 4, are removably connected with and are axially movable in the taper hole 3
Cone block 6, the area of section for boring block 6 is identical with the area of section of taper hole 3 and be fitted close with taper hole 3, and cone block 6 is equipped with in
The locking hole 7 of mandrel line coaxial arrangement, the clamping screw 8 cooperated with tapped blind hole 4, taper hole 3 and screw thread are inserted in locking hole 7
Excessive inclined-plane 9 is equipped between blind hole 4.
The working principle of the present embodiment is: after feed appliance suit end 2 is worn, will lead to feed appliance suit end 2
Diameter becomes smaller, to generate gap with feed appliance, the concentricity difference of feed appliance and main shaft body 1 at this time is larger, using this reality
When with novel technical solution, since the area of section of cone block 6 is identical as the area of section of taper hole 3 and is fitted close with taper hole 3,
So the diameter that feed appliance is set with end 2 is the diameter not worn when boring block 6 and taper hole 3 is fitted close, and works as and grind
After damage, only tightening for clamping screw 8 need to be controlled, it will be able to by the axial movement for going deep into crush cones block 6 of clamping screw 8, by
Annular array is equipped in feed appliance suit end 2 and axially extending strip gab 5, strip gab 5 and spiral shell are carried out by end face
Line blind hole 4 is connected to, so cone block 6 will be set with feed appliance when boring block 6 and continuing to move axially to cone block 6 and enter tapped blind hole 4
End 2 squeezes, and causes the diameter at feed appliance suit end 2 to become larger, to be fitted close with feed appliance.
Embodiment two, as shown in figures 1 and 3, a kind of RG main shaft with lower concentricity difference, including main shaft body 1, it is main
Shaft body 1 is equipped with feed appliance and is set with end 2, and the end face at the feed appliance suit end 2 is equipped with axially extending taper hole 3, cone
The tapped blind hole 4 for being connected with coaxial arrangement in hole 3, feed appliance are set with end 2 and are equipped with annular array and carry out by end face axial
The strip gab 5 of extension, strip gab 5 are connected to tapped blind hole 4, are removably connected with and are axially movable in the taper hole 3
Cone block 6, cone block 6 is bullet and cone block 6 is not fitted close with taper hole 3, and cone block 6 with central axis coaxial equipped with setting
The locking hole 7 set is inserted with the clamping screw 8 cooperated with tapped blind hole 4 in locking hole 7, sets between taper hole 3 and tapped blind hole 4
There is excessive inclined-plane 9.
In the present embodiment when it is implemented, after tightening clamping screw 8, cone block 6 is moved axially, due to boring block 6
For bullet and cone block 6 is not fitted close with taper hole 3, so when boring the end face and excessive inclined-plane 9 for boring block 6 when the movement of block 6
The contact surface of generation is smaller or even is not in contact with excessive inclined-plane 9, so that relatively labor-saving when tightening clamping screw 8.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein, and should not treat any reference in the claims as limiting
Related claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
