Abstract
The invention discloses a method for detecting the internal hardness of steel balls. The method comprises the following steps: fixing the steel balls, using a bench clamp to fix a fixed clamp fixed with the steel balls and provided with a limiting plate, grinding the steel balls, and testing the internal hardness of the steel balls. After the method is adopted, the fixed clamp fixed with the steel balls can fix the steel balls firmly, and the upper half parts of the steel balls are ground through the bench clamp, so that the testing of the internal hardness of the steel balls is carried out conveniently and quickly, and the circulation of unqualified steel balls is prevented. In addition, the limiting plate can limit the grinding heights of the steel balls; while the testing is facilitated, the damage to a grinding wheel or the bench clamp can be prevented. Furthermore, the fixed clamp and the bench clamp are detachable, and all that is needed is to replace the fixed clamp, so that the steel balls with different diameters can be quickly fixed.
Description
Technical field
The present invention relates to a kind of steel ball detection method, particularly the detection method of the inner hardness of a kind of steel ball.
Background technology
Steel ball now application is extremely extensive.Steel ball, especially chromium ball hardness is high, wear-resistant, long service life, therefore cost is also very high.But some manufacturer, for pursuing juice, has adopted cheap chromium plating steel ball, is also on the basis of manganese steel ball in inside, add plating one deck chromium steel ball, when entering factory's detection, hardness detects qualified.But use a period of time, after chromium steel ball wear, inner manganese steel is by Fast Wearing, greatly shorten serviceable life, and production line will frequently be changed steel ball, causes cost to increase, for the sand milling tinuous production of a large amount of use steel balls, the steel ball of Fast Wearing will enter later process, cause the stopping production of production etc.But, the little steel ball of ball shape, especially diameter of steel ball, inner hardness is difficult to again test, therefore, also makes chromium plating steel ball exist in a large number.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provides one can carry out fast the inner hardness test of steel ball, prevents the detection method of the inner hardness of steel ball of defective steel ball circulation.
A detection method for the inner hardness of steel ball, comprises the following steps:
The first step, steel ball is fixed: the lower semi-circular of steel ball is fixed with steel ball stationary fixture;
Second step, stationary fixture is fixed: the stationary fixture that is fixed with steel ball in the first step is fixed with the bench vice of height lifting;
The 3rd step, steel ball grinding: the bench vice in second step is placed on muller board, and lifting bench vice, makes steel ball contact with emery wheel, starts to grind;
The 4th step, the inner hardness test of steel ball: by the hardness of Rockwell Hardness instrumentation examination abrasive surface steel ball.
Described steel ball stationary fixture is the magnetic base with a semicircle orifice at least, and the lower semi-circular of steel ball is adsorbed in semicircle orifice securely.
On described steel ball stationary fixture, be provided with limiting plate, when emery wheel contacts with limiting plate, bench vice will decline automatically, stop grinding.
The height of described limiting plate is 1/3rd of steel ball size.
The present invention adopts after said method, and above-mentioned steel ball stationary fixture can fixedly secure steel ball, and the first half of steel ball can be ground by bench vice, thereby fast and easy is carried out the test of the inner hardness of steel ball, has prevented the circulation of defective steel ball.In addition, limiting plate can limit the grinding height of steel ball, in convenient test, can prevent from damaging emery wheel or bench vice.Further, stationary fixture and bench vice are detachable, only need to change stationary fixture, can fix fast the steel ball of different-diameter.
Embodiment
The present invention is further detailed explanation for just concrete preferred embodiments below.
A detection method for the inner hardness of steel ball, comprises the following steps:
The first step, steel ball is fixed: the lower semi-circular of steel ball is fixed with steel ball stationary fixture.This steel ball stationary fixture is the magnetic base with a semicircle orifice at least, and the lower semi-circular of steel ball is adsorbed in semicircle orifice securely.Semicircle orifice data can arrange according to needing at ordinary times to extract the steel ball number detecting.
Second step, stationary fixture is fixed: the stationary fixture that is fixed with steel ball in the first step is fixed with the bench vice of height lifting.On steel ball stationary fixture, be provided with limiting plate, the height of this limiting plate is steel ball size 1/3rd.Because normal steel ball in use, after 1/3rd steel ball sizes, substantially to consider to change steel ball; In addition, steel ball stationary fixture is fixed on 1/2nd places of steel ball size, then grinds downwards, can contact with bench vice or stationary fixture by emery wheel, can damage emery wheel or bench vice etc.
The 3rd step, steel ball grinding: the bench vice in second step is placed on muller board, and lifting bench vice, makes steel ball contact with emery wheel, starts to grind.When emery wheel contacts with limiting plate, bench vice will decline automatically, stop grinding.
The 4th step, the inner hardness test of steel ball: by the hardness of Rockwell Hardness instrumentation examination abrasive surface steel ball.During test, two points at least choosing on face off carry out, after twice test, averaging.
Claims (4)
1. a detection method for the inner hardness of steel ball, is characterized in that: comprise the following steps:
