[0025] As shown in FIG. Figures 1-5 The utility model discloses a jig for guaranteeing the machining magnesium-aluminum alloy four peripheral flatness, which comprises: a processing platform 1;Fixed plate 2, fixed plate 2 is connected on processing platform 1, and fixed groove 3 is formed in fixed plate 2;Support column 4, three support columns 4 are arranged in the fixed groove 3 in a triangular distribution, and the support column 4 is used for supporting the product 7;Cover plate 5, the cover plate 5 is arranged above the support column 4, and the cover plate 5 is used for pressing the product 7;Pressurizing assembly 6, the pressurizing assembly 6 is arranged in the fixed plate 2, and the fixed plate 2 is used for pressurizing the cover plate 5.
[0026] In the embodiment, by placing the product 7 on the fixed plate 2, a triangular distribution is formed by arranging three supporting columns 4, it is ensured that the contact points of the product 7 on the jig are always the same, so that the error between the contact points is minimized, and the machining error caused by uneven contact surface is avoided. The supporting column 4 contacts at three points of the product 7, without directly acting on the plane of the product 7, avoiding the risk of plane deformation. The cover plate 5 can press the product 7, further ensuring the stability of the product during machining. The cover plate 5 can effectively prevent the product 7 from loosening or shifting during machining, ensuring that the machining reference remains unchanged and further improving the machining precision. By accurately controlling the pressure through the pressing assembly 6, the product 7 can always be in a controlled state during machining, thereby improving the consistency and stability of machining. Through the three-point support, point-to-surface contact, and cover plate pressing method, the problems of inconsistent machining reference and inconsistent product size caused by traditional face-to-face contact jigs are solved.
[0027] The triangular distribution structure of the supporting column 4 allows the supporting force to be evenly distributed on three points, avoiding the instability that may be caused by single-point support. The use of point-to-surface contact instead of face-to-face contact ensures the consistency of the contact point position, which is crucial for the uniformity of the machining reference. Face-to-face support is easily affected by the unevenness of the product surface, leading to uneven contact and affecting the machining precision.
