Abstract
A kind of symmetry measuring device of two cross facets of machining workpiece on the basis of another two sides center, structure are made of wishbone, elongated slot square bar, round bar, dial gauge and thumbscrew.There is a fixed straight pin in the lower right for the leading flank that wishbone is contacted with measurement workpiece, there is an elongated slot square bar fixed by thumbscrew on wishbone trailing flank, circular hole installs round bar on elongated slot square bar, installs dial gauge on one end on round bar.The device is applied in combination with dressing plate, in mechanical workpieces processing, symmetry error of two crossing planes of workpiece on the basis of the central plane of other two plane to be measured.
Description
Technical field
The present invention relates to a kind of measuring device, in particular in mechanical processing process, two crossing planes of workpiece with
Symmetry error measurement on the basis of the central plane of other two plane.
Background technique
Machining at present, especially during pincers worker manual processing, two crossing planes are in other two plane
The workpiece that symmetry on the basis of heart plane requires, representative workpiece have: pentagon, hexagon workpiece.This kind of workpiece symmetry misses
Difference measurements are measured with three-coordinates measuring machine, and measurement accuracy is higher.But in actual operation, single-piece production either pincers worker hand
Work processes this kind of workpiece, when not having three-coordinates measuring machine, can only use three interior tables identical with standard workpiece external surface shape
The template in face measures.Template covers on workpiece measured surface when measurement, according to three quilts of the three of template inner surfaces and workpiece
The contact situation between surface is surveyed, judges that the error condition between workpiece surface is processed by light transmission method, due to being root
According to light transmission capacity error in judgement, error amount cannot be directly read, in addition, measurement process is also easy to measurement error and template occur
Precision the problems such as also influencing measurement accuracy.Workpiece is measured in this way, it is easy to workpiece in process be caused to give up
Product.Therefore, development structure is simple, precision is high, intersects for two in the single-piece production either workpiece of pincers worker manual processing flat
Symmetry error measuring device of the face on the basis of the central plane of other two plane is necessary.
Summary of the invention
The purpose of the present invention is providing in the case where no three-coordinates measuring machine, a kind of structure is simple, manufacture is easy, is surveyed
Measure symmetry measuring device of easy, quick, with high accuracy two cross facet of workpiece on the basis of another two sides center.
In order to achieve the above object, technical solution are as follows: its structure is by wishbone, positioning pin, elongated slot square bar, round bar, butterfly spiral shell
Nail, dial gauge composition.The bottom surface of wishbone and side verticality have a fixed circle at the lower right corner of the front side surface of wishbone
Pin, front side surface of the straight pin perpendicular to wishbone.There is an elongated slot square bar on the rear side surface of wishbone, on elongated slot square bar
There is an elongated slot, thumbscrew is connected and fixed elongated slot square bar with wishbone by elongated slot.The other end of elongated slot square bar has a circle
Hole, Kong Zhongyou round bar, round bar are fixed by thumbscrew on elongated slot square bar end face.There are a circular hole, hole in the front-end surface of round bar
Middle installation dial gauge, dial gauge are fixed by the thumbscrew on round bar front end face.The device and workpiece to be measured are placed on standard
On plate, the side of workpiece is leaned against on wishbone leading flank, a measurement surface of workpiece and cylinder pin contacts, another measurement
Dial indicator measuring head is contacted on surface, the workpiece for having symmetry requirement of two cross facets on the basis of another two sides center can be carried out
Symmetry error measurement.
Detailed description of the invention
Structure Figure below, the invention will be further described.
Fig. 1 is the main view of structure of the invention installation diagram.
Fig. 2 is the A direction view of structure of the invention installation diagram.
The leading flank lower right corner of wishbone 1 is fixedly installed with straight pin 3 in as shown in Figure 1, on the rear side surface of wishbone 1
There is elongated slot square bar 9, elongated slot square bar 9 is connect by the thumbscrew 10 in long slot hole thereon with V shape frame 1, elongated slot square bar 9
Flexible or rotate around thumbscrew 10 adjustable, tightening thumbscrew 10, then its is fixed.The other end of elongated slot square bar 9
On have a circular hole, circular hole installs round bar 6, and round bar 6 makees flexible, rotation adjustment in Kong Zhongke, when tightening 9 end face of elongated slot square bar
On thumbscrew 8 when, then its is fixed.Dial gauge 7, percentage are installed in the circular hole on the periphery of 6 front end of round bar
Table 7 can according to need adjustment insertion depth, thumbscrew 5 be tightened after adjusting, then its is fixed.
First then installation dial gauge 7 is carried out according to the case where 7 bar gauge head 2 measured surface of contact workpiece of dial gauge before measurement
Following adjustment: first unclamping thumbscrew 10, adjusts the extension elongation and rotational angle of elongated slot square bar 6, after tighten thumbscrew 10；
Thumbscrew 5 is unclamped again, the amount of 7 measuring staff extension elongation of dial gauge is adjusted, tightens thumbscrew 5 after suitable；Then butterfly is unclamped
The gauge head bar that screw 8 adjusts dial gauge 7 is vertical with the face measured surface d on workpiece 2, and 2 face measured surface d of gauge head contact workpiece
On point and point on 3 contact workpiece of straight pin, 2 face measured surface c it is symmetrical.After adjusting, thumbscrew 8 is tightened.
When measurement, the device and workpiece 2 are placed on 4 surface of dressing plate, and gauger pins wishbone 1 on the other hand, and the other hand is pressed
Firmly workpiece 2 and toward being pushed forward, contacts the face datum level a of workpiece 2 with the surface of dressing plate 4, on workpiece 2 face measured surface c and
Straight pin 3 contacts, and the face another measured surface d is contacted with the gauge head of dial gauge 7 on workpiece 2.At this point, writing down the pointer of dial gauge 7
Reading value.Then, datum level is exchanged, the face datum level b of workpiece 2 is allowed to contact with the surface of dressing plate 4, makes to be measured surface d
Face is contacted with straight pin 3, and the gauge head of dial gauge 7 contacts the face measured surface c, at this time the reading of dial gauge 7 and last time dial gauge 7
The difference of reading, is exactly the symmetry error value of the face c and the face d of workpiece 2 on the basis of the central plane in the face a and the face b.Measurement accuracy
It is higher than with template measurement accuracy, if dial gauge 7 is changed to amesdial, it is higher to obtain its measurement accuracy., measurement simple with structure is held
Easily, quickly the features such as.
Cast iron can be used in symmetry measuring device of two cross facets of above-mentioned workpiece on the basis of another two sides center, wishbone
Or Steel material production still regardless of making using what material, as long as using this structure, belongs to protection model of the invention
It encloses.
