Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical strengthening technology of metal surfaces, and relates to Alpha gate test pieces, specifically to a standard block type Alpha gate test piece fixing fixture. Background Technology
[0002] Shot peening involves propelling a high-speed stream of shot onto the surface of a part, causing plastic deformation of the surface layer, introducing residual stress, and refining the surface grains. This residual stress can significantly improve the fatigue strength and stress corrosion resistance of the part.
[0003] Shot peening has become a crucial process for our company in improving the fatigue strength and stress corrosion resistance of gears and gear shafts in mining trucks, new energy vehicles, and AMT transmissions, thereby extending the service life of these parts. Shot peening intensity is a key parameter affecting the quality of shot peening; therefore, accurate measurement of shot peening intensity is essential. Shot peening intensity is generally characterized using the arc height value of an Almen specimen. An Almen specimen is a standard sample used to characterize the effect of shot peening. Under the impact of shot, the surface layer of the specimen undergoes plastic deformation, causing the specimen to bend spherically towards the peening surface. The distance between the specific reference surface that cuts into the spherical surface and the highest point of the spherical surface is called the arc height value. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model proposes a standard block-type Alpha gate test piece fixing fixture to solve the technical problem that the arc height value of the Alpha gate test piece in the existing technology cannot truly reflect the shot peening intensity of the part.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A standard block type Alpha gate specimen fixing fixture includes a fixture body, wherein the fixture body includes a specimen base and a connecting shaft, characterized in that:
[0007] The test piece base is connected to a small-thickness standard block, which has a fixing threaded hole. A fixing screw is installed in the fixing threaded hole to fix the Alpha door test piece.
[0008] Alternatively, the test piece base is connected to a thick standard block, and the thick standard block is provided with a fixing threaded hole, in which a fixing screw is installed to fix the Alpha door test piece.
[0009] Alternatively, the test piece base is connected to a small-thickness standard block, which is connected to a large-thickness standard block. The large-thickness standard block is provided with a fixing threaded hole, and a fixing screw is installed in the fixing threaded hole to fix the Alpha door test piece.
[0010] This utility model also has the following technical features:
[0011] The test piece base is provided with countersunk modules at the corners of each end. The countersunk modules have countersunk platforms that are connected to countersunk holes, which are connected to cylindrical threads.
[0012] The front faces of the small-thickness standard block and the large-thickness standard block are respectively provided with bosses, and the bosses are provided with connecting threaded holes; the rear corners of the small-thickness standard block and the large-thickness standard block are also provided with countersunk modules.
[0013] The boss on the front end face of the small-thickness standard block is installed in the sinking platform module of the test piece base, and the boss on the front end face of the large-thickness standard block is installed in the sinking platform module at the end corner of the rear end face of the small-thickness standard block.
[0014] The sinking platform is hollow inside and open on one side.
[0015] Connecting screws are installed in the connecting threaded holes. The connecting screws of the small thickness standard block are connected to the cylindrical threads in the countersunk module of the test piece base for fixing the small thickness standard block and the test piece base. The connecting screws of the large thickness standard block are connected to the cylindrical threads in the countersunk module of the small thickness standard block for fixing the small thickness standard block and the large thickness standard block.
[0016] Weight reduction holes are provided inside the thick standard block.
[0017] The base of the test piece is rectangular.
[0018] The connecting shaft is provided with a through hole.
[0019] The test piece base and the connecting shaft are connected by a threaded connection.
[0020] The test piece base, the small thickness standard block, and the large thickness standard block are each provided with at least four fixing threaded holes.
[0021] Compared with the prior art, the present invention has the following beneficial technical effects:
[0022] (I) The present invention proposes to design tooling blocks of different thicknesses. By combining different numbers and thicknesses of tooling blocks, the distance between the Almen test piece and the spray gun is changed, thus simulating the distance between the part and the spray gun. This allows the arc height value of the Almen test piece to truly reflect the shot peening intensity of the part, which is beneficial for production process control and rapid debugging of new processes. While combining the required tooling thickness, the number of tooling blocks used is reduced. The thicker tooling blocks are designed with weight-reducing holes to avoid serious eccentricity problems and improve tooling combination efficiency.
[0023] (II) The standard block boss structure and the design of adding countersunk holes proposed in this utility model can effectively prevent the connecting screws or cylindrical threads from being sprayed and thus effectively improve the tooling life.
[0024] (III) The present invention proposes a separate design and processing of the test piece base and the connecting shaft, with the two parts connected by a threaded fit, which effectively reduces the processing difficulty of the test piece base. The tooling structure is simple, easy to assemble, and can be flexibly combined according to the required distance. Attached Figure Description
