Description

Technical Field

[0001] The utility model relates to the field of manufacturing and processing, in particular to a leading fixed type angle-adjustable countersinking tool. Background Art

[0002] In the field of aviation assembly, the connection between structural parts is mostly achieved by riveting and screwing. The riveting method requires countersinking of the holes, and the screwing method requires countersinking and chamfering of the holes. This requires countersink drills with different parameters to meet the countersinking requirements, such as 90°, 100°, 120°, etc. For the countersinking of structural holes with different apertures, it is also necessary to customize countersink drills with corresponding smooth guide columns to meet the requirements. For structural holes with greater rigidity, countersink drills are also used for deburring. For deburring of different apertures, there is also a demand for angles. Therefore, countersink drills have a wide range of applications in the field of aviation assembly and there are many types.

[0003] The quality of hole countersinking is related to the blade parameters, material and verticality of the countersink. Therefore, in order to ensure the quality of the product, the countersink drill with a threaded shank must be used strictly in conjunction with the countersink depth limiter during countersinking work, and the countersink drill with a straight shank must be used in conjunction with a drill cup to ensure the verticality requirements.

[0004] In summary, the countersink drills currently in widespread use are of an integrated structure. Countersink drills with a guide are only suitable for holes with a single aperture and a single countersink angle. The cost of use is relatively high, and the guide will also rotate with the countersink drill, which will have a certain destructive effect on the quality of the hole wall. Utility Model Content
