Abstract
The utility model relates to a kind of auxiliary support apparatus for the processing of large scale cylindrical blank bar, including supporing shell, the supporing shell is positioning ring, the circumference of positioning ring is equipped with positioning screw hole, positioning bolt is installed in the positioning screw hole, wherein the positioning ring is hollow structure, and intermediate position is equipped with cylindrical blank bar and holds hole.The utility model simple structure and reasonable design, pass through the cooperation of positioning screw hole and positioning bolt, it is sleeved on when use on cylindrical blank bar, by the length for adjusting positioning bolt, the center of circle when rotation of cylindrical blank bar is set to center of rotation, the out-of-roundness of cylindrical bar is offset, to meet processing needs, reduces machining allowance.
Description
[technical field]
The utility model relates to a kind of auxiliary support apparatus for the processing of large scale cylindrical blank bar, belong to support
Technical field.
[background technique]
Existing large scale cylindrical blank bar is generally highly difficult in vehicle bowlder, and one side size is bigger, another party
Face, so that the precision of vehicle is inconsistent before and after cylindrical blank bar, is easy to cause error, to affect production during vehicle
The quality of product.
[utility model content]
The purpose of this utility model is that: it is in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, and design is closed
Reason, the auxiliary support apparatus easy to use for the processing of large scale cylindrical blank bar.
It is a kind of for large scale cylindrical blank stick that in order to achieve the above purposes, the technical solution adopted by the utility model is:
Expect the auxiliary support apparatus of processing, including supporing shell, the supporing shell is positioning ring, and it is fixed that the circumference of positioning ring is equipped with
Position screw hole, is equipped with positioning bolt in the positioning screw hole, wherein the positioning ring is hollow structure, intermediate position is set
There is cylindrical blank bar to hold hole.
In the present invention: for the positioning screw hole on the positioning ring at least provided with four groups, every group is equipped with symmetrical 2.
In the present invention: the length of the positioning bolt in the positioning screw hole is greater than the thickness of positioning ring, positioning ring
Thickness be greater than 100mm.
In the present invention: the diameter that the cylindrical blank bar holds hole is greater than cylindrical blank bar to be processed
Diameter.
After adopting the above structure, the utility model has the beneficial effect that the utility model simple structure and reasonable design, passes through
The cooperation of positioning screw hole and positioning bolt, when use, are sleeved on cylindrical blank bar, pass through the length for adjusting positioning bolt
Short, the center of circle is set to center of rotation when cylindrical blank bar is rotated, and the out-of-roundness of cylindrical bar is offset, to meet processing
It needs, reduces machining allowance.
[Detailed description of the invention]
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute improper limits to the present invention, in the accompanying drawings:
The structural schematic diagram of Fig. 1 the utility model；
Fig. 2 is the use state diagram of the utility model；
Fig. 3 is the use state side view of the utility model.
In figure: 1, positioning ring；2, positioning screw hole；3, cylindrical stock holds hole；4, cylindrical blank bar；5, tailstock top

[specific embodiment]
Be described in detail the utility model below in conjunction with attached drawing and specific embodiment, illustrative examples therein with
And explanation is only used to explain the utility model, but is not intended to limit the scope of the present invention.
As shown in Figure 1, a kind of auxiliary support apparatus for the processing of large scale cylindrical blank bar, including supporting shell
Body, the supporing shell are positioning ring 1, and the circumference of positioning ring 1 is equipped with positioning screw hole 2, installation in the positioning screw hole 2
There is positioning bolt 8, wherein the positioning ring 1 is hollow structure, intermediate position is equipped with cylindrical bar and holds hole 3.It is described
For positioning screw hole 2 on positioning ring 1 at least provided with four groups, every group is equipped with symmetrical 2.Positioning bolt 8 in the positioning screw hole 2
Length be greater than the thickness of positioning ring 1, because 1 internal diameter of positioning ring is bigger than 4 diameter of cylindrical blank bar, when Raw material processing tune center
It need to be positioned and be adjusted by the length of positioning bolt 8, the thickness that positioning bolt 8 need to stretch out positioning ring 1 is just adjusted, wherein positioning ring
1 thickness is generally higher than 100mm.The diameter that the cylindrical blank bar holds hole 3 is greater than cylindrical blank bar 4 to be processed
Diameter.
When actual processing, as Figure 2-3, first by the assembly of lathe clamping jaw 7 on lathe chuck 6, and according to circle to be processed
4 diameter coarse adjustment lathe clamping jaw 7 of cylindricality blank bar.Then positioning ring 1 is held into 3 sets of hole in circle to be processed by cylindrical stock
The one end at the intermediate position of cylindricality blank bar 4, cylindrical blank bar 4 to be processed is fixed by the levelling of lathe clamping jaw 7, the other end
Fixed by tailstock center 5, cylindrical blank bar 4 to be processed keeps it concentric with both ends, then by adjusting positioning bolt 2
Positioning ring 1 and central frame roller 9 is fixed.The outer circle of positioning ring 1 is contacted with central frame roller 9, fixed in Vehicle Processing original bar
Position ring 1 and central frame roller 9 rotate together, and correct former bar centre so as to reach, and are convenient for Vehicle Processing.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
