Fully-automatic roller sorting machine

Abstract

The invention especially relates to a fully-automatic roller sorting machine, belonging to the field of tapered roller detection technology. According to the invention, the upper end of a frame is provided with a roller feeding mechanism; a turning-around mechanism is arranged on the part, below the roller feeding mechanism, of the frame; a detection turntable is arranged on the part, below the turning-around mechanism, of the frame; a detection ring extending outwardly is arranged on the edge of the upper end of the detection turntable; a plurality of detection holes are evenly arranged in the detection ring at an equal interval; the middle position of each detection hole is vertically provided with a material hole which penetrates the whole detection ring; a baffle plate is attached ontothe lower end surface of the detection ring; two ends of one of the detection holes are provided with a group of measuring mechanisms; the parts, corresponding to the material holes, of the baffle plate are provided with gaps extending from exterior to interior; and the parts, out of the gaps, of the frame are provided with blanking plates driven by a rotary cylinder. The fully-automatic roller sorting machine in the invention realizes automatic orientation, turning-around, detection and sorting of rollers, and is high in automation degree and improved measurement precision and the like.

Description

technical field [0001] The invention relates to the technical field of tapered roller detection, in particular to a fully automatic roller sorting machine. Background technique [0002] At present, in the industry, the diameter measurement of tapered rollers of many small and medium-sized manufacturers is still in the manual measurement stage, and tapered roller measuring instruments are used for measurement. Some fully automatic measuring equipment has also appeared, but it has not been able to measure the nominal angle of the tapered roller. The error caused by the nominal angle of the tapered roller is currently neglected in China, but the nominal angle of the tapered roller will also affect the clearance, rotation accuracy, friction torque, vibration and noise of the tapered roller bearing, so the tapered roller The nominal angle is also one of the main accuracy indicators. [0003] At present, the sorting machine on the market is to locate the non-processed surface of...

AI Technical Summary

Problems solved by technology

[0003] At present, the sorting machine on the market is to locate the non-processed surface of the small end surface of the roller, instead of positioning the ball base surface of the large end, so the positioning is not accurate and reliable, the measurement repeatability is poor, and the accuracy value cannot reach the advertised value. 0.5μm, the bumps between the rollers are also obvious

[0004] The pneumatic control signals of some tapered roller sorters are transmitted by many cam mechanisms, resulting in a large sorting volume and slow slideway blanking, which affects the sorting efficiency; in addition, the inductive measuring head is pressed down during measurement. , the measurement force is also large, which may easily cause damage to the measuring head. The measured value is the diameter of the ellipse, not the true value of the diameter of the roller.
