Ball pen ball refers to " ball " on ball pen head, and nib is the key that ball pen, and nib is divided into as pen tip
On ball and ball seat body.The production of ball pen ball and ball seat body, either equipment or raw material at present, for a long time all
It rests in Switzerland, Japan and other countries hand.The production of ball pen pearl ball is very high to having in the precision of processing, the selection of material
It is required that.
The production of ball pen ball has the precision of processing very high requirement.The size and shape of ball（Main includes straight
Diameter, circularity, surface roughness）Most important running parameter in being produced as ball pen ball, with the hardness of ball, micro-
Tissue, ratio of defects etc. collectively form the whether qualified important inspection parameter of a ball pen ball.
China is maximum ball pen big producer in the world, produces more than 400 hundred million ball pens every year.But in ball
On pen pearl and the production of ball seat body, there are still the missings of core technology at present in China.Although Taiyuan Iron and Steel Co. has now been developed 2.3 millis
The stainless steel wire of rice, and put into the production of ball pen head so that China's core technology deficient phenomena slightly improves.But
In the production of ball pen head, still there is gaps with some developed countries for China.One of the main reasons for this is domestic current
There are no the ultra precise measurement system to ball pen bead sizes and shape measure, lead to not understand import ball pen ball
Some design parameters, the further research to import ball pen ball is cannot achieve, to hinder to ball-pen point
Further investigation.
For current present situation, ball pen ball is developed and produced although domestic, it is existing non-to connect
Touch optical measuring device is only capable of realizing the function of measuring its dimensional parameters, to its form parameter carry out data acquisition with
Analysis, and contact type measurement is because ball pen ball volume is too small, fixation problem not yet solves, and can not carry out ball pen ball
Shape data acquires and analysis, greatly affected the technology development of ball pen ball.Therefore, it is necessary to invent a kind of contact
Ball pen bead sizes form measuring instrument and measurement method.

Above air-float turntable 7, it is on switch 11, manipulation regulation button 10 makes accurate inductance probe 4 to special fixing device 6
On ball pen ball 13 carry out data acquisition, the data of acquisition are transferred to computer terminal 12 by accurate inductance probe 4, into line number
According to processing, graphic plotting, diameter, circularity and the surface roughness of ball pen ball are calculated, and judges to be tested whether ball is conjunction
Lattice product and roughness grade.
If Fig. 2 is to as shown in figure 4, the special fixing device 6 in the present invention includes needle point 6-1, hose 6-2, plastic box again
6-3, air bag 6-4, plastic suckers 6-5, needle point pedestal 6-6, check valve 6-7.The ball pen ball 13 and needle point 6-1 is logical
Absorption connection is crossed, accurate inductance probe 4 is contacted with ball pen ball 13, and needle point pedestal 6-6 and check valve 6-7 passes through screw thread
It is connected, needle point pedestal 6-6 is clamped fixation with scroll chuck 5, and outlet side and the hose 6-2 of check valve 6-7 are connected
It connecing, hose 6-2 is passed through above scroll chuck 5 and is attached with plastic box 6-3, and air bag 6-4 is inserted into plastic box 6-3 and connects,
Plastic box 6-3 is fixedly connected with plastic suckers 6-5, and plastic suckers 6-5 is connected with air-float turntable 7 by adsorbing.
As shown in figure 3, the needle point pedestal 6-6 outer diameters in the present invention are more than check valve 6-7 outer diameters, exist convenient for scroll chuck 5
Preferably in same axle center when fixed needle point pedestal 6-6,13 centre of sphere institute of ball pen ball is more preferably found convenient for accurate inductance probe 4
Diameter.
As shown in figure 5, the top interior design of needle point 6-1 in the present invention, which is the lower conical surface, constructs 6-8, increase and spherical surface
Leakproofness, the apical lateral of needle point 6-1 uses upper cone structure 6-9, avoids connecing for accurate inductance probe 4 and needle point 6-1
It touches, ball pen ball 13 is preferably contacted convenient for accurate inductance probe 4.
When special fixing device fixes ball pen ball：Ball pen ball 13, needle point 6-1, check valve 6-7, hose 6-2,
After plastic box 6-3 and plastic suckers 6-5 is attached fixation, ball pen ball 13 is placed in conical surface 6-8 under the tops needle point 6-1
Place, air bag 6-4 are attached when in suction condition with plastic box 6-3, and the air inside special fixing device is sucked away
Later, being formed by pressure difference with ambient atmosphere inside needle point 6-1 can make ball pen ball 13 be stably fixed to needle point top
The lower cone structure position 6-8 in end, since check valve 6-7 not will produce backflow phenomenon, when measuring, air bag 6-4 can be from special solid
Determine to remove on device, while ball pen ball 13 is not fallen out.

13 surface pivots of pearl carry out data acquisition, unsmooth due to 13 surface of ball pen ball so that accurate inductance probe 4 has
Different signal output, reaches computer terminal 12 by collected signal, carries out processing and the arbitrary shape of data, be calculated
Diameter, circularity and the surface roughness of ball pen ball, and judge to be tested whether ball pen ball 13 is that certified products and surface are thick
Rugosity grade.
It is illustrated in figure 6 the work flow diagram of one-shot measurement, ball pen ball is fixed first, then starts measuring instrument,
Hardware initialization obtains sphere center position, and whether then judge accurate inductance probe contact is that ball pen ball crosses the straight of the centre of sphere
Diameter, if then accurate inductance probe carries out data acquisition to the diameter of the centre of sphere excessively, if not centre of sphere diameter excessively then continues to judge,
The data of acquisition pass to host computer, and host computer carries out data processing, arbitrary shape, calculate the diameter of ball pen ball, circularity and
Surface roughness, and judge to be tested whether ball is certified products and roughness grade.
Present apparatus calculated diameter is by being measured respectively in 0 ° of workbench and 180 ° of positions workpiece, recycling two groups of numbers
According to algorithm evaluation is carried out, diameter measurement is realized.
The present apparatus is evaluated to deviation from circular from minimum two-multiply law, with respective points on tested circle contour to circumference
The quadratic sum of distance is that the center of circle of minimum circle is the center of circle, and the semidiameter for making to contain two concentric circles for being tested circle contour is to justify
Spend error.
The present apparatus uses the average arithmetic deviation value of profileRaSurface roughness is evaluated, length is centainly being measuredn
It is interior, average arithmetic deviation of each point to center line apart from absolute value on profile.Its calculation formula is：
RaIt is worth smaller, illustrates that ball pen ball surface roughness grade number is higher.
According to《People's Republic of China's light industry standard ball pen tungsten carbide ball》QB/T 4433-2012, individually
Ball pen ball diameter tolerance is positive and negative to be no more than 0.001mm, and ball deviation from circular from requires to be not more than 0.0004mm, surface roughness
Table of grading 1,
1 roughness grade table of table
Judge to be tested whether ball pen ball is certified products and roughness grade.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of the claims
