[0020] The utility model will be further explained in detail in combination with the drawings and the embodiment. It can be understood that the specific embodiment described here is only used to explain the utility model, and not limit the utility model. In addition, it needs to be explained that, in order to facilitate the description, only the part related to the utility model is shown in the drawing, not all structures.
[0021] In the description of the utility model, unless another explicit provision and limitation, the term "link", "connect", "fix" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integral;Can be mechanical connection, also can be electrical connection;Can be directly connected, also can be indirectly connected through the intermediate medium, can be the communication of two elements or the interaction of two elements.

[0024] The utility model embodiment provides a kind of shot coverage contrast test tool, as shown in Figure 1 The utility model provides a kind of shot coverage contrast test tool, as shown in
[0025] The utility model provides a kind of shot coverage contrast test tool, as shown in
[0026] In some embodiments, card 1 is transparent material, and the area of pattern 2 is opaque.
[0027] As shown in Figure 1As shown, the card 1 and the pattern 2 have obvious color difference, which is beneficial for the human eye to identify and contrast. In other embodiments, the card 1 and the pattern 2 can be regions with different colors, respectively, so that the human eye can obviously distinguish the regions of the pattern 2 in order to compare the coverage. It can be understood that the shot regions of the shot process are randomly hit by the shots, and there are cases of separation, combination, tangency and intersection between the circles formed by the hit diameters of the shots, so there is a certain error in the case of simply counting the number. The pattern 2 on the card 1 of the utility model is also composed of multiple circles 3, but the coverage is used as the judgment basis instead of the number of circles 3, that is, the pattern 2 is compared, so the accuracy and efficiency of the contrast test of the coverage can be improved.
[0028] In some embodiments, the card 1 is of a film material. The film material has good transparency, good toughness and easy processing performance, which is easy to process the pattern 2 on the card 1, and then obtain the pattern 2 region with obvious contrast on the transparent card 1, which is beneficial for the human eye to identify and improve the detection efficiency and protect the human eye.
[0029] In some embodiments, the pattern 2 is made on the card 1 by laser drawing. The drawing effect of laser drawing is a vector pattern, which has high positioning accuracy compared with methods such as screen printing and laser etching, and the edges of the pattern 2 are neat, which can obtain the structure of the circle 3 consistent with the shot diameter as much as possible, and then obtain the card 1 with standard coverage. The texture of the pattern 2 on the card 1 is clear and wear-resistant, which can be used repeatedly for a long time and is easy to operate, saves time, and can be applied to engineering.
[0030] In some embodiments, the card 1 is provided with multiple cards 1, and the shapes and sizes of the multiple cards 1 are the same and the coverages of the patterns 2 are different.
[0031] It can be understood that when the coverage of the pattern 2 on the card 1 and the coverage of the product to be tested have a large difference, two or more cards 1 can be used for contrast test. Since the card 1 is of a transparent material and the pattern 2 is a black region, two or more cards 1 can obtain a pattern 2 with higher coverage after being stacked, until the coverage of the stacked pattern 2 is consistent with the coverage of the product to be tested. The values of the coverages of the multiple cards 1 are fitted, and the coverage of the card 1 or the fitted coverage is the shot coverage of the product to be tested. It should be noted that the multiple cards 1 used for stacking detection have different coverages of the patterns, so as to avoid large overlap and affect the detection effect.
[0032] In some embodiments, the card 1 is rectangular. The card 1 with a regular shape is beneficial for multiple cards 1 to be completely overlapped for contrast detection, and then only a certain number of cards 1 with fixed coverage need to be set, and the contrast test can be realized by combining stacking and fitting calculation, thereby saving the cost of card 1 production.
[0033] In some embodiments, the surface area of card 1 is smaller than the area of the shot-peened region of the product under test. In actual testing, the shot-peened region on the product under test is uniform; therefore, it is generally sufficient to select a portion of the shot-peened region for comparative inspection. By using a smaller card 1, it is easier to find an area within the shot-peened region that more closely resembles the pattern 2 on card 1, thus facilitating rapid comparative inspection.
[0034] In some embodiments, the coverage of pattern 2 is 10%, 20%, 30%, 40%, or 50%.
[0035] like Figures 1-2 As shown, this embodiment of the invention provides five standard cards 1 (10mm × 10mm), with pattern 2 coverage rates of 10%, 20%, 30%, 40%, or 50%, respectively. Figure 1 and Figure 2 These are the cases with coverage rates of 10% and 50%, respectively. The coverage rates for other values can be obtained by superimposing and numerically fitting the coverage rates of these five standard cards 1. It should be noted that the pattern 2 on each card 1 is made individually, using multiple randomly distributed circles 3. The fitted values of the pattern 2 coverage rates from multiple superimposed cards 1 can be set up in a fitting table for easy checking and verification, quickly obtaining the coverage rate.
[0036] When using the shot peening coverage comparison inspection tool provided by this utility model to conduct shot peening coverage comparison inspection on the product under test, firstly, based on the target coverage of the product under test (shot peening part or test piece), select one card 1 with the target coverage or multiple cards 1 with a fitted coverage equal to the target coverage; select an area on the product under test that is the same size as card 1, and circle the selected position with a marker; compare one card 1 or multiple superimposed cards 1 with the circled area; based on visual comparison, appropriately increase or decrease cards 1 with different coverage until the coverage (or fitted coverage) of card 1 is the same as the coverage of the product under test; record the coverage and number of cards 1 (if multiple cards 1 are superimposed) to achieve the shot peening coverage of the product under test, in order to determine whether it meets the shot peening requirements.
[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
