Step height detection mechanism

Abstract

The invention relates to a step height detection mechanism comprising a top detection mechanism and a bottom detection mechanism arranged opposite to the top detection mechanism in a vertical direction. A top cylinder connecting plate is fixed at the top of a supporting column through a top cylinder telescopic end fixed by a top cylinder mounting seat; and a top mounting plate is supported and fixed on the top surface of the top cylinder connecting plate through a supporting rod. A plurality of through holes I for placing top pen type displacement sensors are formed in the top mounting plate;and top limiting rings are installed in the through holes I respectively. A top detection rod mounting base is fixed on the bottom surface of the top cylinder connecting plate; and through holes II for arranging top detection rods are formed in the top detection rod mounting base and the top detection rod mounting base. The top pen type displacement sensors and the top detection rods are abutted and connected in the through holes II. Top detection rod springs sleeve outsides of the top detection rods. One end of each top detection rod is a circular truncated cone and the other end is provide with a spring clamp slot for clamping one top detection rod spring. Therefore, the detection of the height difference of different steps in the part is automatically completed.

Description

technical field [0001] The invention relates to an automatic detection device on a production line, in particular to a step height detection mechanism. Background technique [0002] At present, the existing production mode is a semi-automatic assembly line operation. When the upper sequence of workpieces flows to this process, manual sampling inspection is performed. Each product requires 1-2 minutes of inspection time, and manual records are required to count the defective rate. Since there are different steps on the front and back of parts, it will cause low production efficiency, high labor intensity for inspectors, inaccurate CPK statistics, and daily output cannot meet processing needs. [0003] In view of the above problems, the main technical problem to be solved by the present invention is to provide a step height detection mechanism that is widely used in production practice and has the advantages of wide application range, large batch size, short process time and s...
