Abstract
The utility model discloses a kind of quick-clamping positioning core axles, including main shaft, it is provided with ball at the top of described main shaft one end and keeps set, it on the main shaft and keeps one end of set to be provided with spring strength positioned at ball and adjusts screw, and spring strength adjusts screw and keeps set through ball and extend to the inside of main shaft, the two sides that the spring strength adjusts screw are symmetrically arranged with spring, and the ball keeps being provided with spacer pin at the top of the one end covered.The quick-clamping positioning core axle keeps set, spring and spring strength to adjust screw by setting ball, adjusts screw by spring and spring strength and promotes main shaft in situ, it is fixed using spacer pin, and in the state of nature, under the action of the spring, ball holding effect, so that mandrel can not fall, when ball keeps set to stir, and ball has space dynamic inward, the reason of by strength, so that ball is walked inwards, mandrel is extracted easily, to realize quick-clamping positioning core axle.
Description
Technical field
The utility model belongs to virtue and social course teaching aid technical field, and in particular to a kind of quick-clamping locating core
Axis.
Background technique
When processing annular workpieces, when needing inner hole and datum level to position, and at processing with the geometric tolerance at positioning compared with
Gao Shi must just use reliable positioning method, but when progress clamping, operation is more troublesome, so that working efficiency is influenced, and
And being easy to happen inclination causes the axle center of workpiece and workbench inconsistent, so that the precision of workpiece is influenced, so needing to design
A kind of quick-clamping positioning core axle solves the problems, such as this.
Utility model content
The purpose of this utility model is to provide a kind of quick-clamping positioning core axles, to solve to propose in above-mentioned background technique
The problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of quick-clamping positioning core axle, including master
Axis is provided with ball at the top of described main shaft one end and keeps set, on the main shaft and is located at ball one end of set is kept to be provided with
Spring strength adjusts screw, and spring strength adjusts screw and keeps set through ball and extend to the inside of main shaft, the spring
The two sides that strength adjusts screw are symmetrically arranged with spring, and the ball keeps being provided with spacer pin at the top of the one end covered, described
Main shaft and ball keep being provided with ball between set.
This setting keeps set, spring and spring strength to adjust the interaction relation between screw using ball, so that will lead
Axis promotes in situ, so that keeping workpiece axle center to be overlapped with the axle center of mandrel, and in the state of nature, in the effect of spring
Under, ball holding effect, so that mandrel can not fall, when ball keeps set to stir, and ball has space dynamic inward, stress
The reason of amount, extracts mandrel easily so that ball is walked inwards, to realize quick-clamping positioning core axle, Er Qieke
To keep workpiece axle center to be overlapped with the axle center of mandrel, the precision of workpiece is improved.
Preferably, one end of set is kept to be provided with guide angle on the main shaft and far from ball, and angle is 30 degree.
Preferably, there are four the quantity of the ball.
This setting reduces the frictional force that main shaft generates in the process of movement using ball, increases its service life.
The technical effect and advantage of the utility model: the quick-clamping positioning core axle keeps set, spring by setting ball
Adjust screw with spring strength, screw adjusted by spring and spring strength and promotes main shaft in situ, using spacer pin by its
It is fixed, and in the state of nature, under the action of the spring, ball holding effect, so that mandrel can not fall, when ball is kept
Set is when stirring, and ball has space dynamic inward, the reason of by strength, so that ball is walked inwards, mandrel is pulled out easily
Out, to realize quick-clamping positioning core axle, and workpiece axle center can be kept to be overlapped with the axle center of mandrel, improves the essence of workpiece
Degree.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 ball keeps set, 2 spacer pins, 3 springs, 4 balls, 5 spring strength to adjust screw, 6 main shafts.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of quick-clamping positioning core axle as shown in Figure 1, including main shaft 6, the main shaft 6 one
It is provided with ball at the top of end and keeps set 1, on the main shaft 6 and is located at ball one end of set 1 is kept to be provided with spring strength tune
Screw 5 is saved, and spring strength adjusts screw 5 and keeps set 1 through ball and extend to the inside of main shaft 6, the spring strength tune
The two sides of section screw 5 are symmetrically arranged with spring 3, are provided with spacer pin 2, the master at the top of one end of the ball holding set 1
Axis 6 and ball keep being provided with ball 4 between set 1.
Specifically, keeping one end of set 1 to be provided with guide angle on the main shaft 6 and far from ball, and angle is 30 degree.
Specifically, there are four the quantity of the ball 4.
The quick-clamping positioning core axle by the way that positioning core axle to be overlapped with workpiece spindle axle center, then passes through bullet when in use
Spring force amount adjusts the cooperation of screw 5 and spring 3 so that push the operation in situ of main shaft 6, after end of run by spacer pin 2 by its
It is fixed, and in the state of nature, under the action of spring 3,4 holding of ball effect so that mandrel can not fall, works as rolling
Pearl keeps set 1 when stirring, and ball 4 has space dynamic inward, the reason of by strength, so that ball 4 is walked inwards, so that mandrel can
To extract easily, to realize quick-clamping positioning core axle, and workpiece axle center can be kept to be overlapped with the axle center of mandrel, improved
The precision of workpiece.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
