Problems solved by technology
Regardless of the direct Rockwell hardness HRC test or the crushing force test, the steel ball will be damaged, and it cannot be used for 100% hardness test of the steel ball.
In addition, this random inspection method is accidental, and it cannot guarantee that the hardness of the rest of the steel balls are qualified.
However, the hardness of special-purpose steel balls in key components must be 100% qualified, but there is currently no equipment that can inspect steel balls without damage and 100% with high efficiency.

Embodiment Construction
[0014] refer to Figure 1-2 , the steel ball automatic sorting machine of the present invention has a frame 8, a support frame 6 is fixed on the frame 8, a motor 1 is fixed on the support frame 6, and the porous turntable 2 fixed to the shaft end of the motor 1 is placed on the support frame In the steel ball container 4 fixed on 6, an inclined plane 7 is arranged on the machine base 8 directly below the steel ball outlet provided at the bottom of the steel ball container 4, and a sample is set on the machine base 8 at the far end of the inclined side of the inclined plane 7. The box 9 is provided with two chambers separated by a partition 10 in the sample box 9 . In the steel ball holder 4, there is a blocking piece 3 for preventing the steel balls from overlapping. The diameter of the steel balls inspected in this embodiment is Φ10mm. The steel ball holder 4 is placed at a relative height of 300mm from the inclined plane 7. The inclined plane 7 and the horizontal plane of t...

Abstract
The invention relates to the metering technology field and provides a method for testing the hardness of steel balls and an automatic sorting machine thereof. The method comprises the following steps: the steel balls to be tested are arranged in a position at a certain height; the orderly free-falling steel balls fall on an inclined surface which forms a certain angle with a horizontal surface; the steel balls are thrown along the horizontal direction in the form of a parabola by the effect of slant horizontal component; according to the distance range of throwing the steel balls, the hardness range of the steel balls is sorted and determined; a supporting frame is fixed on the machine base of the automatic sorting machine; a motor is fixed on the supporting frame; a porous rotary table fixedly connected with the shaft end of the motor is arranged in a steel ball containing tool fixed on the supporting frame; a steel ball outlet is arranged at the bottom part of the steel ball containing tool; an inclined surface is arranged on the machine base under the steel ball outlet; a sample box is arranged on the machine base at the far end of an inclined side of the inclined surface; two chambers separated by a baffle plate are arranged in the sample box. The method for testing the hardness of the steel balls is simple, the tested steel balls can not be damaged, and the sorting correct rate is 100 percent; furthermore, the testing method has the advantages of simple structure, high sorting efficiency, low cost, etc.
Description
technical field [0001] The utility model relates to a steel ball automatic sorting machine related to the technical field of metrology and inspection. Background technique [0002] The hardness of the steel ball is one of the main technical indicators of the quality of the steel ball. Since the surface of the steel ball is a spherical surface instead of a plane, especially the steel ball with a diameter of Φ<10mm, it is impossible to directly perform the Rockwell hardness test. The test method for the hardness of the steel ball is known. According to the national standard GB / T308-2002 "Rolling Bearing Steel Balls", the method of crushing force is used, and no less than 9 steel balls are taken from each batch of finished products for the crushing force test. The crushing force≮the standard appendix The requirements in C are qualified. No matter the direct Rockwell hardness HRC test or the crushing force test will cause damage to the steel ball, it cannot be used to test t...
