Abstract

The invention relates to the technical field of magnetic powder inspection, in particular to a feeding mechanism for a pin-shaped part fluorescent magnetic powder inspection machine, which comprises a rack, a fixed bracket, a movable bracket and a driving assembly, wherein the fixed bracket comprises a fixed supporting plate and a connecting plate; the movable bracket comprises a movable supporting plate, a vertical guide rod, a transverse guide rod, a vertical guide sleeve, a transverse guide sleeve, a second bidirectional lead screw, a second bearing seat, a second hand wheel, a first sliding rail, a first sliding block and a first mounting plate; and the driving assembly comprises a second mounting plate, a first air cylinder, a second air cylinder, a second sliding rail and a second sliding block. According to the feeding mechanism for the pin-shaped part fluorescent magnetic particle flaw detector, the feeding mechanism runs in a full-automatic mode in the feeding process, wherein multi-station feeding work is completed through one-time running. The feeding mechanism is high in working efficiency, the width of the fixed supporting plate and the width of the movable supporting plate can be adjusted according to the specifications of workpieces, adaptability is high, and the feeding mechanism can operate safely and stably.

Description

technical field [0001] The invention relates to the technical field of magnetic particle flaw detection, in particular to a feeding mechanism for a fluorescent magnetic particle flaw detection machine for pin-shaped parts. Background technique [0002] Magnetic particle flaw detection uses the interaction between the leakage magnetic field at the defect of the workpiece and the magnetic powder. It uses the difference between the magnetic permeability of the surface of the steel product and the near-surface defects (such as cracks, slag inclusions, hairlines, etc.) and the magnetic permeability of the steel. After magnetization, these The magnetic field at the discontinuity of the material will be distorted, forming a part of the magnetic flux leakage, and the leakage magnetic field will be generated on the surface of the workpiece, thereby attracting the magnetic powder to form the magnetic powder accumulation at the defect - the magnetic trace, which shows the position and s...
