A steel ball drop and impact test device

Abstract

The invention discloses a device used for a steel ball drop and impact test. The device used for the steel ball drop and impact test comprises a screw elevator and a dropping straight pipe, wherein the screw elevator is arranged obliquely, the top end of the screw elevator is connected with the top of the dropping straight pipe, an impacting straight pipe is installed outside the dropping straight pipe, a plurality of inserting holes are evenly formed in the outer wall surface of the impacting straight pipe, a cuboid stop block is inserted into each inserting hole, and the volume, inside the impacting straight pipe, of each stop block is one fourth of the total volume of the stop block. The device used for the steel ball drop and impact test has the advantages that relevant conditions required by the drop test are met due to the arrangement of dropping pipelines and steel ball runways with corresponding sizes, drop and impact tests of steel balls with different specifications can be achieved, split detection is facilitated, smooth proceeding of the steel ball drop test can be ensured, a drop test of steel balls with different diameters can be achieved, transmission is achieved by the screw elevator, and the efficiency of a field test involved with steel balls with different specifications is improved.

Description

technical field [0001] The invention relates to the technical field of steel ball detection equipment, in particular to a steel ball drop and impact test device. Background technique [0002] Steel balls are widely used in bearings, hardware, electronics, iron art, mechanical equipment, electric power, mining, metallurgy and other fields. . The post-process of steel ball production, that is, automatic cleaning of steel balls, appearance inspection, anti-rust, counting and packaging, are the keys to the quality of steel balls. The appearance inspection of steel balls mainly includes the detection of surface scratches, rust, and surface spots. Among them, the steel ball drop equipment is a special equipment used by the steel ball production enterprise to ensure the quality and service life of the steel ball product for the drop test. The existing similar equipment generally uses chain lifting and other conveying devices, while ignoring the steel ball. The shape and structure...

Problems solved by technology

Among them, the steel ball drop equipment is a special equipment used by the steel ball production enterprise to ensure the quality and service life of the steel ball product for the drop test. The existing similar equipment generally uses chain lifting and other conveying devices, while ignoring the steel ball. The shape and structure of the test bracket and the drop pipe, for example, these structures can only smoothly send the steel ball from the bottom of the conveying equipment to the top point to be dropped, which makes all steel balls have only one detection method, that is, one pipe , a height and the same number of drops, which cannot meet the different detection requirements of steel ball users

At the same time, because the equipment only passes the test of one pipe, it is easy to affect the efficiency of the test due to the different specifications of the steel balls
