Description

Technical Field

[0001] The utility model belongs to the technical field of drilling devices for pallet nuts, and particularly relates to a drilling die for pallet nuts. Background Art

[0002] When the drilling die tool for pallet nuts is involved in aircraft assembly, various access covers and aircraft structures use pallet nuts to be installed on the fuselage. Generally, standard pallet nut parts are used for matching drilling. The inner walls of the bolt holes and rivet holes of the pallet nuts are easily damaged. During use, it is difficult to accurately grasp the wear condition of the pallet nuts. If used directly, it will cause the risk of the hole diameter becoming larger and resulting in the access cover being out of tolerance. The bushing added to the inner wall of the rivet hole of the drilling die for pallet nuts can ensure that the inner wall of the drilling die for pallet nuts can be directly replaced with a bushing. In this case, the drilling accuracy can be well guaranteed. Summary of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a drilling die for pallet nuts that can quickly locate the drilling position and ensure the drilling accuracy.

[0004] The utility model is realized through the following technical solutions:

[0005] A drilling die for pallet nuts includes a scale with graduations and a slider; a strip-shaped slot hole is arranged in the middle of the scale, and a corresponding strip-shaped groove is also arranged above the strip-shaped slot hole; the slider is movably installed in the strip-shaped groove on the scale and can slide along the strip-shaped groove; a pointer pointing to the graduations on the scale is arranged in the middle of the slider; a hole one is arranged in the center of the slider; holes two are arranged on the slider on both sides of the hole one; the drilling die for pallet nuts further includes a positioning pin inserted into the holes two for positioning; bushings are arranged on both the hole one and the holes two.

[0006] Advantages of the Utility Model

[0007] The structure of the utility model is simple. By sliding the slider, the drilling position can be quickly and accurately found, saving time and labor, shortening the production cycle, and ensuring the product quality. Brief Description of the Drawings
