Double-tube steel ball free falling equipment

Abstract

The invention discloses double-tube steel ball free falling equipment comprising a spiral lifter and a falling straight tube. The spiral lifter is arranged in an inclined mode, the top of the spiral lifter is connected with the top of the falling straight tube, the outer side of the falling straight tube is provided with a falling bent tube, the top of the falling bent tube is connected with the top of the spiral lifter, and a movable cover is arranged on the connecting portion of the falling bent tube and a bottom sliding channel. The equipment has the advantages that due to arrangement of a falling pipeline and a steel ball runway with corresponding sizes, conditions for relative falling experiments are met, requirements of steel balls of different specifications are met, shunting detection is facilitated, smooth steel ball falling experiments are guaranteed, the steel balls in different diameter ranges can be used for falling tests, transmission is achieved through the spiral lifter, and efficiency of on-site experiments in different scales is improved due to the double-tube structure composed of the straight tube and the bent tube.

Description

technical field [0001] The invention relates to the technical field of steel ball detection equipment, in particular to a double-tube type steel ball free fall equipment. 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 is automatic cleaning of steel balls, appearance inspection (rejecting unqualified products), rust prevention, counting and packaging, all of which are the key to the quality of steel balls. The appearance inspection of steel balls mainly includes surface scratches, rust, surface Detection of spots etc. 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...

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
