Embodiment Construction

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] See Figure 1 to Figure 3 , The drill sleeve provided by the embodiment of the present invention is used for processing large-angle small holes, and includes a cemented carbide drill sleeve body 1. The cemented carbide drill sleeve body 1 can improve the strength of the drill sleeve and is effective This avoids the wear of the drill bit on the drill mold. Preferably, the strength of the drill sleeve body 1 is greater than the stre...

Abstract

The invention discloses a drill bushing and a drill jig with the same. The drill bushing and the drill jig with the drill bushing are used for machining large-angle small holes. The drill bushing comprises a drill bushing body made of hard alloy. A special-shaped portion is arranged at the first end of the drill bushing body, and a drill bit protrudes out of the drill bushing from the special-shaped portion; the end face of the special-shaped portion is an inclined face, and a machining hole is formed in the drill bushing body in the axial direction of the drill bushing body. The drill bushing is made of hard alloy and better in rigidity and abrasion resistance, can better protect the drilling jig and prolong the service life of the drill jig, and therefore machining cost is reduced. In addition, the special-shaped portion of the drill bushing can match the drill jig and the structure of a part to be machined, and a locating function is achieved; the drill bit can be guided through the machining hole in the drill bushing, and the vibration energy of the drill bit in the drilling process can be reduced; and therefore, machining stability is improved, and a machined hole is higher in precision and better in use performance.

Description

Technical field [0001] The invention relates to the technical field of mechanical processing, and more specifically, to a drill sleeve for processing large-angle small holes. In addition, the present invention also relates to a drilling jig with the above-mentioned drill sleeve. Background technique [0002] In the machining process of mechanical parts, it is usually necessary to machine holes on the parts. When machining holes, drill holes are often used, and the drill sleeve can be used to determine the position of the machined holes on the parts, guide the drill bit to process, and improve the drilling process The stability. However, when machining mechanical parts, some products usually need to be processed with small holes, which can penetrate a hole with a sinker on the part with a certain hole series. [0003] At present, when processing large-angle small holes, because the size of the hole is small, a drill is generally used to directly drill the small hole, and there is ...
