Description

Technical Field

[0001] The present invention relates to the technical field of identification and detection of microscopic defects of pellets, and specifically to a detection device for detecting the surface state of pellets. Background Art

[0002] Shot peening is to spray a high-speed shot stream onto the surface of a part, causing plastic deformation on the surface layer of the part to form a strengthening layer with a certain thickness. A relatively high residual stress is formed within the strengthening layer. Due to the existence of compressive stress on the part surface, when the part bears a load, a part of the stress can be offset, thereby improving the fatigue strength of the part;

[0003] However, in the mass production process, only the strengthening effect that can be achieved by the shot peening equipment is emphasized, while the wear and microscopic defects of the pellets themselves are ignored, which often leads to an unsatisfactory strengthening effect. The strengthening effect is not only related to the composition, quality, density, hardness, etc. of the pellets, but also closely related to the size, shape, microscopic defects and wear degree of the pellets. This will determine whether the pellets can always obtain the same stable kinetic energy output under the same equipment conditions, so as to obtain a stable shot peening strengthening effect and the implantation of residual compressive stress.

[0004] In the process of pellet detection, according to international standards, it is necessary to detect a layer of pellets covering a certain unit area and observe the number and proportion of damaged pellets. For this reason, we need a special tool for checking the pellet breakage rate.

[0005] Based on this, a detection device for detecting the surface state of pellets is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

Detailed implementation manners

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] In one embodiment, as Figure 1-Figure 14 shown, a detection device for detecting the surface state of pellets includes a base 1. The base 1 is in an inverted U shape. A detection plate 3 is slidably connected to the upper surface of the base 1. A parameter area 7 corresponding to the detection range of pellets is provided on the upper surface of the detection plate 3.

[0040] Embodiment 1:

[0041] The holes for the detection plate 3 to detect are square.

[0042] The sizes of the detection holes of the detection plate 3 can be of various sizes, and the thicknesses of the detection plates 3 with different detection hole sizes are also different. The larger the hole, the thicker the detection plate 3, which is convenient for detecting shot peening of different sizes or different materials.

[0043] Since the most intuitive expression of pellet wear is the change in pellet diameter, and the higher the wear, the smaller the diameter. According to this characteristic, when selecting the detection plate 3, a 304 stainless steel plate with the same thickness as the pellet before wear should be selected for comparison; when it is necessary to detect the wear and breakage rate of the pellets, first check the parameter area 7 corresponding to the detection range of pellets on the detection plate 3 according to the diameter of the pellets to be detected. According to the parameter area 7 corresponding to the detection range of pellets, select a suitable detection plate 3, place the detection plate 3 completely on the base 1, then place the pellets to be detected into the detection holes, and pull the detection plate 3 back and forth to make the pellets evenly distributed in the detection holes. Use a magnifying glass to observe the wear condition of the pellets, and then compare it with reference to the parameter area 7 corresponding to the detection range of pellets on the detection plate 3. Record the wear degree of the shot peening.

[0044] The pellet detection range corresponds to the parameters in parameter area 7, refer to Fig.12 .

[0051] In one embodiment, the lower shell body 5 includes a ring gear 11 and a gear 12. The upper surface of the lower shell body 5 is connected to the ring gear 11 through a bearing.

The threaded rods 21 are threadedly connected to the threaded cylinders 19.

[0052] When the second rotating handle 14 is turned, the second rotating handle 14 drives the ring gear 11 to rotate, the rotation of the ring gear 11 drives the rotating shaft 13 to rotate, the rotation of the rotating shaft 13 drives the threaded barrel 19 to rotate, and the rotation of the threaded barrel 19 cooperates with the threaded rod 21 to quickly achieve the purpose of overall lifting and lowering adjustment of the upper shell 4 and the lower shell 5.

[0054] During the observation process, the first rotating handle 6 can be turned by hand, and the first rotating handle 6 drives the frosted glass 10 to rotate. The surface of the frosted glass 10 is relatively rough, which can drive the pellets in the detection port to rotate, so that the wear of the pellets can be observed in all directions, thereby improving the detection effect of the pellets;

[0055] By turning on the remote control LED light 9, the light passes through the frosted glass 10, making it more convenient for the staff to observe the pellets.

[0056] In one embodiment, a rubber handle 8 is fixedly connected to the side wall of the detection board 3 .

[0057] It is convenient for the staff to pull the detection plate 3 back and forth.

[0058] In one embodiment, rubber pads are provided on the upper surfaces of the first rotating handle 6 and the second rotating handle 14 .

[0059] In one embodiment, two symmetrical limit blocks 2 are fixedly connected to the inner wall of the base 1 , and the limit blocks 2 are slidably connected to the detection plate 3 .

[0060] The detection plate 3 is limited.

[0061] The above embodiment discloses a detection device for detecting the surface state of pellets, and its specific working principle and process are as follows:

[0062] S1: First, adjust the size of the detection port surrounded by the six variable diameter blocks 15 according to the size of the pellets to be detected;

[0063] The second rotating handle 14 is turned by hand, and the second rotating handle 14 drives the rotating circle 22 to rotate, and the rotation of the rotating circle 22 drives the second guide rail 17 to rotate, and the rotation of the second guide rail 17 drives the second slider 18 to slide, and then the six diameter-changing blocks 15 move in the direction of the first guide rail 16 through the cooperation and limitation of the first guide rail 16 and the rotating circle 22, so as to adjust the size of the detection port surrounded by the six diameter-changing blocks 15, and can be quickly adjusted according to pellets of different sizes, and the adjustment operation is fast and convenient;

[0064] S2: When the second rotating handle 14 is turned, the second rotating handle 14 drives the gear ring 11 to rotate, the rotation of the gear ring 11 drives the rotation shaft 13 to rotate, the rotation of the rotation shaft 13 drives the threaded barrel 19 to rotate, the threaded barrel 19 rotates and cooperates with the threaded rod 21 to quickly achieve the purpose of overall lifting and lowering adjustment of the upper shell 4 and the lower shell 5;

[0065] When the pellets to be tested are larger, the test port surrounded by the six reducer blocks 15 becomes larger, and because the upper shell 4 and the lower shell 5 rise as a whole, the depth of the test port surrounded by the six reducer blocks 15 becomes deeper, and vice versa, ensuring that the size of about half of the pellet diameter is consistent with the depth of the test port. In this case, the pellets will not roll out of the test port, and the wear of the pellets can be clearly and obviously observed;

[0066] S3: Place the pellets in the adjusted detection port, hold the rubber handle 8 and shake the detection plate 3 back and forth, the detection plate 3 shakes so that the pellets are evenly distributed in the detection port, which facilitates better observation of the pellets;

[0067] S4: Observe the pellets in the detection port through a microscope or a magnifying glass, and then refer to the parameter area 7 corresponding to the pellet detection range to determine the wear condition of the pellets;

[0068] During the observation process, the first rotating handle 6 can be turned by hand, and the first rotating handle 6 drives the frosted glass 10 to rotate. The surface of the frosted glass 10 is relatively rough, which can drive the pellets in the detection port to rotate, so that the wear of the pellets can be observed in all directions, thereby improving the detection effect of the pellets;

[0069] By turning on the remote control LED light 9, the light passes through the frosted glass 10, making it more convenient for the staff to observe the pellets.

[0070] S5: After the test is completed, the pellets can be stuck out of the test port with tape, and the pellets can be left on the tape for experimental records.

[0071] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
