Description

Technical Field

[0001] This utility model relates to the field of drill bit processing technology, specifically, a quick inspection and comparison block for gun drill regrinding. Background Technology

[0002] When machining slender holes using machining centers or drilling and tapping centers, the most important machining geometry for gun drills is the inner and outer angles. This is because they significantly affect chip formation, hole accuracy, and surface roughness, requiring high precision in tool parameters. This is especially true for high-strength materials, where drill bits wear easily and require frequent resharpening to ensure machining quality. (See attached image) Figure 1 As shown, the tip of a commonly used gun drill typically includes an oiled surface 15, an inner cutting edge clearance angle 16, a tip clearance angle 17, a clearance angle 18, an inner cutting edge 19, and an outer cutting edge 20. During regrinding, the angles of the inner cutting edge 19 and the outer cutting edge 20 are the focus of inspection. However, inspecting the inner and outer angles (Kγ1, Kγ2) of the tool after regrinding is time-consuming, and the regrinding quality is inconsistent, requiring rework, resulting in low efficiency. Tool parameters need to be adjusted according to the characteristics of the material being processed, and the subtle and precise adjustments require considerable experience, posing a significant challenge for beginners and those lacking experience, making it difficult to improve efficiency and resulting in inconsistent regrinding quality.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0020] This embodiment provides a quick inspection comparison block for gun drill grinding, specifically as follows: Figures 1-3 As shown, the device includes a body 11, on which multiple detection slots 13 are provided. Each detection slot 13 has a limiting surface 131, an outer cutting edge detection surface 132, and an inner cutting edge detection surface 133. The outer cutting edge detection surface 132 is connected to the inner cutting edge detection surface 133. The limiting surface 131 and the outer cutting edge detection surface 132 are each connected to a limiting surface 131, and the two limiting surfaces 131 are arranged in parallel. The limiting surface 131 is used to limit the tip of the gun drill, the outer cutting edge detection surface 132 is used to detect the angle of the outer cutting edge 20, and the inner cutting edge detection surface 133 is used to detect the angle of the inner cutting edge 19.

[0021] Based on actual production needs and previous processing experience, a rectangular blank of appropriate size is selected, and multiple test slots 13 of different specifications are made on it to form the comparison block disclosed in this solution. Then, the drill bit is re-sharpened, and the matching of the drill bit tip parameters is frequently checked using the test slots 13 with corresponding parameters. Based on the matching results, the defective points are reworked, and the matching test is performed again until it is qualified.

[0022] Because the quick-test comparison block is portable and can be used anytime and anywhere, it avoids the complexity of using professional equipment; moreover, the quick-test comparison block is simple to manufacture and has low processing costs; it has a fast response, and the tool tip parameters can be compared immediately after sharpening, and defects can be repaired in a timely manner.

[0024] This embodiment further expands upon the above embodiment in that the main body 11, specifically as follows: Figure 2 As shown, a hanging hole 12 is provided through the end of the main body 11.
