Description
Technical field
The present invention relates to a kind of toolings of clamping workpiece, more specifically to a kind of processing of clamping bearing housing workpiece
Tooling.
Background technique
Bearing housing includes inner circle and outer circle, in the case where inner circle has completed the process, Excircle machining will with it is processed
The inner circle of completion is coaxial.In process, the prior art is usually to carry out clamping to bearing housing with chuck, uses dial gauge
Centering processing, but this mode clamping is laborious, and centering is time-consuming, if being also easy to cause processing waste product without clamping.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of bearing housing processing tools, can guarantee interior in process
Outer circle is coaxial.
In order to achieve the above object, the present invention takes following technical scheme:
A kind of bearing housing processing tool, including collar bush and first vertex of a cone, the tail portion of first vertex of a cone is from the inside of collar bush
It is embedded in the bottom center of collar bush, the top of first vertex of a cone is connect with one end of a spring, the other end of spring and the second cone
The top on top connects, and the tail portion of second vertex of a cone is exposed from the top of collar bush, and the top of the tail portion of second vertex of a cone and collar bush
Back of the body cap is provided at the gap of formation；First vertex of a cone, spring and second vertex of a cone are on straight line；
The tail end central vertical contact of second vertex of a cone has live center, and live center pushes up second vertex of a cone towards the direction of first vertex of a cone
Tightly；
The inner wall of collar bush is also embedded in and is fixed with locating piece；Resilient material is filled between spring and the inner wall of collar bush；
Locating piece connect fastening with elastic material by locating piece bolt.
As an improvement project, the bottom of collar bush is also provided with for collar bush to be fixed on lathe spindle packing
Packing positioning bolt, to facilitate the fixation of collar bush.
Preferably, the center hole contacted with live center is offered in the tail end center of second vertex of a cone, to prevent live center
It is detached from.
Optionally, the quantity of locating piece bolt is two.
It is an advantage of the current invention that held out against the direction of second vertex of a cone towards first vertex of a cone by center hole with live center, the
As soon as the vertex of a cone and second vertex of a cone will jointly compress elastic material, thus elastic material can rise by bearing housing workpiece
Tightly, to guarantee automatically inside and outside concentric；And the setting for passing through locating piece, so that it may be provided for the bearing housing workpiece in process
Holding power, to prevent its bias；If needing to cancel the clamping of bearing housing workpiece after processing is completed, live center need to only be cancelled and be held out against
State, the thrust that spring applies will push up first vertex of a cone and second vertex of a cone toward the direction away from other side, to allow from elastic material
Material is no longer on tensioner state, can thus loosen bearing housing workpiece.
Detailed description of the invention
Fig. 1 is the sectional view of the bearing housing workpiece of tooling institute of the present invention clamping；
Fig. 2 is the sectional view for the tooling of the present invention that clamping has bearing housing workpiece；
Fig. 3 is the sectional view of tooling of the present invention.
Specific embodiment
A specific embodiment of the invention is described with reference to the accompanying drawing.
Be as shown in Figure 1 the sectional view of the bearing housing workpiece 1 of this tooling institute clamping, the bearing housing workpiece 1 include outer circle and
Inner circle has marked the first axis platform 101 and the second axis platform 102 in figure, they belong to the interior circular portion of bearing housing workpiece 1 and same
Axis.External circular portion is needed to be processed during processing, such as the face to be processed 103 marked in figure.Dress is illustrated now
Press from both sides the tool structure of the bearing housing workpiece 1.
As shown in Fig. 2, bearing housing workpiece 10 is inserted into from bottom by collar bush 1, collar bush 1 itself is also hollow；First
The tail portion of the vertex of a cone 21 is from the bottom center for being internally embedded collar bush 1 of collar bush 1, the top of first vertex of a cone 21 and a spring 3
One end connection, the other end of spring 3 connect with the top of second vertex of a cone 22, and the tail portion of second vertex of a cone 22 is from the top of collar bush 1
End is exposed, and is provided with back of the body cap 6 at the tail portion of second vertex of a cone 22 and the gap of the top of collar bush 1 formation；First vertex of a cone 21, bullet
Spring 3 and second vertex of a cone 22 are on straight line.
The tail end center of second vertex of a cone 22 is also provided with center hole 4, center hole 4 and 5 perpendicular contact of live center and is pushed up by living
Point 5 is held out against；
The inner wall of collar bush 1 is also embedded in and is fixed with locating piece 7；Spring 3 is also enclosed with elastic sleeve 8, and (this fills elastic material
One embodiment of material)；Locating piece 7 connect fastening with elastic sleeve 8 by two locating piece bolts 71.
The bottom of collar bush 1 is also provided with the packing positioning bolt for collar bush 1 to be fixed on to lathe spindle packing 9
10。
After clamping, 1 inner wall of collar bush is tightly attached in the outside of elastic sleeve 8.
The tooling being illustrated in figure 3 after removing bearing housing workpiece 1.
In use, bearing housing workpiece 10 is mounted on collar bush 1, pass through center hole 4 for second vertex of a cone with live center 5
22 lower section into figure is held out against, and first vertex of a cone 21 and second vertex of a cone 22, will be jointly by elastic sleeve 8 to extending out once shorten spacing
, thus 10 tensioner of bearing housing workpiece (can be tightly attached to collar bush in the outside of this namely above said elastic sleeve 8
The meaning of 1 inner wall), to guarantee automatically inside and outside concentric；And pass through the setting of locating piece 7, so that it may for the axis in process
It holds case workpiece 10 and holding power is provided, to prevent its bias.During fixing bearing case workpiece 10, live center 5 will be pushed up always
Firmly center hole 4；If needing to cancel the clamping of bearing housing workpiece 10 after processing is completed, live center 5 need to only be cancelled and hold out against state, bullet
The thrust that spring 3 applies will push up first vertex of a cone 21 and second vertex of a cone 22 toward the direction away from other side, thus allow from elastic sleeve 8 to
It inside contracts, can thus loosen bearing housing workpiece 10.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
