Background
The impact test has strict requirements on the notch of the impact sample, and the small change of the notch can cause errors in test results, so that the notch processing quality detection of the notch is an important control means for ensuring the qualified notch of the processed impact sample.
The traditional method for detecting the notch processing quality of the impact sample comprises the following steps: before detection, the impact sample is horizontally placed on the ground glass plate, an LED parallel light source is placed below the ground glass plate, a high-pixel far-core camera is placed above the ground glass plate and is right opposite to the notch position of the impact sample, during detection, the LED parallel light source is adopted to irradiate the notch of the impact sample from the bottom, the high-pixel far-core camera is used for projecting and shooting the outline of the impact sample into a photo, the shot image is imported into computer software for analysis processing, after the analysis processing, the positioning boundary and the symmetry line are automatically determined, standard deviation in all directions is given according to the standard geometric shape, and whether the impact sample is qualified is automatically judged.
In the traditional detection method, as the impact sample is horizontally placed on the ground glass plate and is not fixed, a detection person can easily shift the impact sample due to vibration of a detection instrument when debugging other structures, so that the problem that the position of the impact sample is possibly required to be debugged after the completion of debugging occurs, and the time and the labor are wasted, the impact sample is fixed by an auxiliary device during the current detection, and the repeated debugging of the impact sample is avoided.
Fig. 1 is a schematic structural diagram of an auxiliary detection device for an impact sample notch instrument in the prior art, when the conventional device is used, an impact sample is placed in a clamping groove 301, moved to a first notch 102 through a slide way 302, and adjusted through a sample adjusting space until the impact sample notch is overlapped with the first notch 102 to stop, at this time, when the notch measuring instrument detects the notch of the impact sample, lamplight can directly detect whether the notch of the sample reaches a specified depth through the first notch 102, so that the notch depth of the impact sample can be measured rapidly, and the measurement efficiency is improved.
The inventors of the present application found that: when the conventional device detects one impact sample to detect another impact sample, the impact sample needs to be moved out through the slide way 302, then a new impact sample is taken out, and then the impact sample is moved to the first notch 102 through the slide way 302, so that time and labor are wasted, and the detection effect is poor.
