Technical field
This utility model relates to lathe measurer field, especially a kind of lever centring means.
Background technology
Nowadays machining is more and more higher for the requirement of precision, and the precision of many milling machines and machining center has been difficult to full
Foot Production requirement: a lot of processing workpiece still have the problem of dimensional discrepancy, most Producing reason to be that in clamping process, location is inaccurate,
Especially location, the center of circle, because generally using a point middle rod to carry out location, the center of circle, needs reciprocal measurement repeatedly, and location efficiency is low, and deposits
In higher error.
Summary of the invention
In order to overcome the technical deficiency of current centring means, this utility model provides a kind of lever centring means, knot
Structure is simple, easy to use, it is possible to the center of circle to cylinder or circular hole that completes rapidly and efficiently positions and seek limit operation.
This utility model solves its technical problem and be the technical scheme is that a kind of lever centring means, including dress
Put main body, magnetic location block, the trapezoidal slide block with slide block axle, slide block fastening bolt, dial gauge, dial gauge fix bolt, arc
Axle fixed by shape lever, spheric probe and arc lever；Apparatus main body designs for L-shaped, and L-shaped Basolateral one jiao is set to circular arc,
The bottom end on apparatus main body circular arc side is provided with arc lever, and arc lever fixes axle and apparatus main body phase by arc lever
Connect；Spheric probe is located at the other end top of arc lever；L-shaped apparatus main body top is provided with dovetail groove；Trapezoidal slide block and swallow
Stern notch matches setting, can slide in dovetail groove；The apparatus main body L-shaped bending place corresponding with dovetail groove is provided with slide block fastening
Bolt, for being locked to the trapezoidal slide block after adjusting；The apparatus main body other end is connected with dial gauge, passes through percentage
Table is fixed bolt and is fixed；Magnetic location block is the cuboid block that centre is provided with before and after's through-going recess；Groove is cuboid；Recessed
One sidewall of groove is made up of Magnetitum.
The beneficial effects of the utility model are, a kind of lever centring means, and simple in construction can be rapidly completed difference straight
The high precision fixed core location of footpath cylinder or circular hole；In conjunction with magnetic location block, can the most efficiently find the standard working edge of sheet material,
Being effectively improved machining accuracy, compact, carry easy to use, simple to operate easy to learn, popularization is strong.
Accompanying drawing explanation
Further illustrate this use is novel with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural scheme of mechanism of the present utility model.
Fig. 2 is slide block side view of the present utility model.
In figure, 1. apparatus main body, the most trapezoidal slide block, 3. slide block axle, 4. slide block fastening bolt, 5. dial gauge, 6. dial gauge
Fixing bolt, 7. arc lever, 8. spheric probe, 9. axle fixed by arc lever, 10. magnetic location block.
Detailed description of the invention
Referring to the drawings, a kind of lever centring means, including apparatus main body 1, magnetic location block, ladder with slide block axle 3
It is solid that shape slide block 2, slide block fastening bolt 4, dial gauge 5, dial gauge fix bolt 6, arc lever 7, spheric probe 8 and arc lever
Dead axle 9；Apparatus main body 1 designs for L-shaped, and L-shaped Basolateral one jiao is set to circular arc, the bottom on apparatus main body 1 circular arc side
Place is provided with arc lever 7, and arc lever 7 is fixed axle 9 by arc lever and is connected with apparatus main body 1；Spheric probe 8 is located at arc
The other end top of shape lever 7；L-shaped apparatus main body 1 top is provided with dovetail groove；Trapezoidal slide block 2 and dovetail groove match setting, can
Slide in dovetail groove；The apparatus main body 1 L-shaped bending place corresponding with dovetail groove is provided with slide block fastening bolt 4, for adjustment
After trapezoidal slide block 2 be locked；Apparatus main body 1 other end is connected with dial gauge 5, fixes bolt 6 by dial gauge
Fix；Magnetic location block 10 is the cuboid block that centre is provided with before and after's through-going recess；Groove is cuboid；One of groove
Sidewall is made up of Magnetitum, for adsorbing the sheet edge at institute's deckle.
During use, the slide block axle 3 of the application device is gripped and is arranged on machine tool chief axis, adjusting apparatus main body 1
Put, then adjusting apparatus main body 1 adjusts range along dovetail groove direction；Arc lever 7 is utilized to contact dial gauge 5 gauge outfit to determine machine
Tool machining accuracy.
When operating for feeling relieved, manual rotation machine tool chief axis so that main shaft and the lever centering dress being clamped on main shaft
Put and rotate together, adjust main shaft and the height of main shaft upper lever formula centring means and the range of lever centring means, until thick stick
The spheric probe 8 of rod-type centring means contacts cylinder external diameter or the bore inner diameter of required centering, again rotate machine tool chief axis and
Lever centring means, rotating 360 degrees, finely tune lever centring means range during rotation, until dial gauge 5 pointer keeps not
Dynamic, then the center of circle of cylinder or circular hole is concentric with machine tool chief axis.
When limit operation sought by sheet material, find the X of square sheet material correspondence lathe, Y-axis initial point.Magnetic location block 10 is adsorbed
In sheet material edge, manual rotation machine tool chief axis so that main shaft revolves together with the lever centring means being clamped on main shaft on one side
Turn, adjust main shaft and the height of main shaft upper lever formula centring means and the range of lever centring means, until lever centering
The spheric probe of device is placed in the approximate center location of magnetic location block, finely tunes lever centring means range, when spheric probe 8
Touch dial gauge 5 number of degrees of magnetic location block 10 two side identical time, illustrate that main shaft is positioned at the center of magnetic location block 10, deduct
The half of magnetic location block 10 width, then for the initial point of 10 contact plate edges of magnetic location block.
