Crack detection device

Abstract

The invention discloses a crack detection device, which comprises a workbench, a bracket, a rotary machine table, a first actuator, a guide mechanism, a pressing mechanism and a camera. The support and the rotary machine table are arranged on the workbench. The first actuator and the guide mechanism are arranged on the bracket. The pressing mechanism is arranged on the guide mechanism and locatedright above the rotary machine table. The first actuator is used for driving the pressing mechanism to vertically move along the guide mechanism to fix a work piece placed on the rotary machine table.The camera is arranged on one side of the rotary machine table and used for collecting images of the work piece. The device is simple in structure and convenient to operate. Image acquisition is carried out by rotating the work piece 360 degrees, and crack detection on the surface of the work piece is thus achieved. Through active rotation of the rotary machine table and passive rotation of the pressing mechanism, the stability of the work piece during rotation is guaranteed. Through a conical pressing block and a cone-frustum-shaped base, the position of the work piece can be adjusted and fixed, and the work piece can rotate about the central axis thereof.

Description

technical field [0001] The invention relates to the detection field, in particular to a crack detection device. Background technique [0002] Such as figure 1 as shown, figure 1 Shown is a schematic structural diagram of a fuel injector for a gasoline engine, the bottom 83 is in a stepped structure, and a tubular structure 84 extends upwards, and the inside is a through hole. And this workpiece is used in gasoline engine, has higher requirement to it, if crack appears on the surface, there will be certain potential safety hazard in use. Therefore, it is necessary to detect cracks on the surface. However, existing manufacturers usually use manual detection, that is, workers detect cracks on the surface of the workpiece through a microscope. It can be seen that a lot of manpower will be wasted through manual inspection, which will greatly increase production costs; and the accuracy rate is low, and false detections often occur; the most important thing is that workers use m...
