In the later operation process, the operating state of the ball testing mold unit can be adjusted accordingly through the telescopic adjustment of the telescopic pressing column 4.

[0018] Embodiment 2:

[0019] On the basis of the first embodiment, the rotation adjustment unit includes three components: a support column 5, an extension arm 6 and a telescopic clamping arm. The support column 5 has a predetermined working height and supporting force, and a predetermined working distance is left between the support plate 1, so that corresponding load-bearing and limiting operations can be performed. The extension arm 6 is connected to the support column 5, has a predetermined working length and supporting force, and can perform corresponding connection and positioning operations. The telescopic clamping arm is rotatably connected to the extension arm 6, has a predetermined working length and elasticity, and can perform corresponding rotation and telescopic adjustment operations. In the later operation process, the rotation adjustment of the telescopic clamping arm can drive the ball inspection mold unit as a whole to perform corresponding flipping adjustment, so as to facilitate the corresponding bearing steel ball size detection operation. The telescopic clamping arm includes three components: a connection block 7, a first clamping arm 8, and a second clamping arm 9; the connection block 7 is rotatably connected to the extension arm 6, and has a predetermined telescopic property, and can be adjusted in a predetermined range of telescopic and rotation; the first clamping arm 8 is connected to the connection block 7, and can be adjusted to a corresponding working position following the telescopic adjustment of the connection block 7; the second clamping arm 9 is connected to the connection block 7, and a predetermined working distance is left between the first clamping arm 8, and can be adjusted to a corresponding working position following the telescopic adjustment of the connection block 7. The initial working position of the first clamping arm 8 is located at the lower end position of the working direction of the connection block 7, and the initial working position of the second clamping arm 9 is located at the upper end position of the working direction of the connection block 7, and a predetermined working distance is left between the first clamping arm 8 and the second clamping arm 9. In the later operation process, the first clamping arm 8 and the second clamping arm 9 can be adjusted to the corresponding working position through the telescopic adjustment of the connecting block 7, thereby changing the working distance between the first clamping arm 8 and the second clamping arm 9, thereby driving the ball testing mold unit to adjust the corresponding working distance. The ball testing mold unit includes two components: a ball clamping plate 10 and a ball testing plate 11. The ball clamping plate 10 is connected to the first clamping arm 8, has a predetermined working size, and the working surface is uniformly distributed with hemispherical grooves of the predetermined working size. The ball testing plate 11 is connected to the second clamping arm 9, has a predetermined working size, and is provided with a through hole of a corresponding predetermined size, in which a pressing plate 12 is slidably provided; the working surface of the pressing plate 12 is uniformly distributed with hemispherical ball receiving grooves that match the hemispherical grooves provided on the ball clamping plate 10. The working surface of the ball-holding plate 10 is provided with a rubber ball-holding layer 13 having a predetermined working size and flexibility; the working size of the rubber ball-holding layer 13 is adapted to the working size of the ball-holding plate 10. In the later working process, the bearing steel ball to be inspected can be placed on the surface of the rubber ball-holding layer 13 of the ball-holding plate 10, and then the ball-testing plate 11 is pressed accordingly, so that the bearing steel ball can be held in the rubber ball-holding layer 13.

[0020] Based on the above embodiments, the working process of the utility model is as follows: first, the bearing steel ball to be size-detected is placed at the rubber ball-locking layer 13 on the working surface of the ball-locking plate 10, and arranged in sequence according to the working positions of the hemispherical grooves. At this time, the working distance between the first clamping arm 8 and the second clamping arm 9 is in the maximum distance state, that is, the connecting block 7 is in an extended state. Then, the connecting block 7 is made to perform a corresponding contraction operation, driving the first clamping arm 8 and the second clamping arm to approach each other, so that the bearing steel ball placed at the rubber ball-locking layer 13 can be wrapped. Next, the telescopic pressure column 4 is extended in the direction close to the pressing plate 12, and the pressing plate 12 is pressed, so that the bearing steel ball placed at the rubber ball-locking layer 13 that meets the corresponding size requirements can be pressed only in the rubber ball-locking layer 13 for positioning. Then, the telescopic pressure column 4 is retracted again to leave a corresponding working distance. Finally, the connecting block 7 is rotated to drive the first clamping arm 8 and the second clamping arm 9 to flip, and then the working positions of the ball clamping plate 10 and the ball testing plate 11 are switched and flipped. Then the connecting block 7 is extended again to separate the first clamping arm 8 from the second clamping arm 9. At this time, the bearing steel balls that are too large or too small, that is, those that do not meet the corresponding size requirements, can fall into the hemispherical ball receiving groove provided on the pressing plate 12, and the defective products can be sorted out.

[0021] In a further preferred embodiment, the support and pressing assembly and the rotating ball testing assembly can be integrally supported and limited by corresponding bases. In the present application, each component can be driven by a corresponding motor, which is a prior art and will not be described in detail in the present application.

Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
