Description
Technical field
The invention belongs to Computerized Numerical Control processing technology fields, are related to a kind of high-precision dial gauge for numerical control machining center.
Background technology
In NC Machining Process, it is often necessary to the installation bow and arrow in the shape and site error and lathe of part
Accurate centering.But existing measurement generally uses the assembly method that table rod set and dial gauge ontology are interference fitted with dial gauge.
Due to being used in dedicated amount together tool using by dial gauge rod set clamping when measuring workpiece using dial gauge every time, examining
It looks into whether dial gauge is fastened on the accuracy for influencing measurement data on the neat tool of dedicated amount to prevent the when of measuring from having gap, measures
Personnel often rotate dial gauge ontology to check whether there is loose phenomenon, can make between dial gauge ontology and rod set for a long time
There is loosening, and then influences measurement effect.In addition, existing dial gauge is in measurement process, due in order between table bar and rod set
Often clearance fit, in order to ensure the trigger sensitivity of measurement head, the gap between table bar and rod set is enough, still, this
Sample results in lateral sliding measurement process, inevitably to shift and generate between table bar and rod set to connect
It touches, has seriously affected the Surveying Actual Precision of dial gauge.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind being used for digital control processing
The high-precision dial gauge at center.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of high-precision dial gauge for numerical control machining center, including dial gauge main body, are separately mounted to dial gauge master
Body upper and lower ends and the upper rod set and low stem casing being interference fitted with dial gauge main body, and across the table bar of the rod set, it is described
Table bar bottom end is also equipped with measurement head, the low stem casing also milled out with the position of dial gauge body contact it is axial parallel with it
Locking plane, the dial gauge main body back side corresponds to the locking plan-position and is machined with tapping counterbore, by being attacked with described
The silk matched branch head screw of counterbore, which is tightened, resists the locking plane, to locked low stem casing and dial gauge main body.
Preferably, the locking planar recess is in low stem casing casing and being formed with and match branch head screw end
Locking slot, when branch head screw stretches into locking slot and resists locking plane, locked and fixed between low stem casing and dial gauge main body.Under
It is machined with the setting of the locking slot of locking plane in rod set, can be screwed into locking slot in branch head screw and resists locked plane
When, can a coupling mechanism force all axially and radially applied to low stem casing and dial gauge main body, and then lower beam can be effectively prevent
Rotation between set and dial gauge main body.
It is furthermore preferred that being also cased with the spring washer for resisting dial gauge body outer surface on the branch head screw.Spring pad
The arrangement of circle can effectively improve the anti-loosening effect of branch head screw.
Preferably, it is machined with the ball annular groove perpendicular to its axial direction on the low stem casing and the inner wall of upper rod set,
It there also is provided prominent inner wall surface and the ball being in rolling contact with the table bar in ball annular groove.In low stem casing and upper rod set
It is disposed with ball on wall and is in rolling contact with table bar, can effectively reduce the friction between table bar and low stem casing/upper rod set inner wall
Power, and then improve the measurement sensitivity of table bar.Further, since the setting being in rolling contact, slides axially not influencing table bar along it
It realizes under the premise of measuring, the gap between table bar and low stem casing/upper rod set inner wall can also further decrease, and then improve table
Radial positioning effect between bar and low stem casing etc. so that table bar is only capable of moving along its axis, so as to avoid measurement process
In the error brought radially deflected due to table bar, improve measurement accuracy.
It is furthermore preferred that the ball annular groove is arranged in equal spacing with multiple tracks in an axial direction, institute is covered in per pass ball annular groove
State ball.
Preferably, percentage watch back cover is also fixedly mounted in the dial gauge main body back side, is also machined on percentage watch back cover
With the matched locating slot in branch head screw head.The arrangement of locating slot can not only play percentage watch back cover and dial gauge main body
Between location and installation, at the same time it can also resist branch head screw head, to effectively avoiding the loosening of branch head screw to low stem casing
Locked between dial gauge main body has an impact.
It is furthermore preferred that being fixed using gland screw between the percentage watch back cover and dial gauge main body, in gland screw
On be also arranged with the elastic component for resisting the dial gauge main body.The structures such as spring may be used in elastic component, play dial gauge
Flexibility between rear cover and dial gauge main body is fixed, effectively increases the anticollision performance of percentage watch back cover.
Compared with prior art, the invention has the characteristics that：
(1) it is screwed on dial gauge ontology with branch head screw and withstands low stem casing, prevent from loosening, solve dial gauge ontology under
Loosening between rod set strengthens the accuracy of measurement, improves product quality, can be applied to similar survey by certain improvement
The transformation of amount special measuring tool.
(2) structures such as ball annular groove and ball are set so that upper and lower rod set is used with table bar is completely newly in rolling contact mode,
Frictional force is not only reduced, measurement sensitivity is improved, in addition, the radial direction for further improving table bar and upper and lower rod set is fixed
Position effect avoids the table bar in measurement process and deflects the error brought, improves measurement accuracy.
(3) arrangement of locating slot not only increases its location and installation effect between dial gauge main body on percentage watch back cover
Fruit, moreover it is possible to the anti-loosening raising further protection of branch head screw.In addition, the setting of gland screw upper elastic member then can be into
One step improves the cushioning ability of entire dial gauge.
