Description

Technical Field

[0001] The utility model relates to a boring tool structure for processing the track of a housing. Background Art

[0002] A boring tool is a kind of boring tool, generally with a round shank, and there are also square tool bars for larger workpieces. The most common applications are internal hole machining, reaming, profiling, etc. It has one or two cutting parts and is a tool specifically used for rough machining, semi-finishing or finishing of existing holes. The boring tool can be used on a boring machine, a lathe or a milling machine.

[0003] Due to the small space inside some housings, ordinary machining methods can no longer carry out precise machining on their tracks. The traditional machining uses a round nose tool to process the tracks, but this machining method has low machining efficiency and the burrs on both sides of the tracks cannot be completely removed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art and provide a boring tool structure for processing the track of a housing.

[0005] A boring tool structure for processing the track of a housing includes a boring tool main body and a tool body. The tool body includes a base. Knife heads are provided at both ends of the base, and cutting edges are provided on the knife heads. The center of the base is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected inside the boring tool main body.

[0006] Preferably, the base is of a cuboid structure, the knife heads are of a square structure, the upper section surface thereof is an inclined surface, and cutting edges are provided on the inclined surface. The two knife heads are symmetrically arranged with the center point of the base as the reference.

[0007] Preferably, the tool body and the rotating shaft are fixedly connected by bolts. A threaded hole is provided at the center of the base, and a threaded structure is provided on the inner side wall of the rotating shaft. The bolts sequentially pass through the threaded hole on the base and the rotating shaft.

[0008] Preferably, a first positioning groove for inserting the rotating shaft is provided at the port of the central threaded hole of the base. Second positioning grooves for inserting positioning blocks are provided on both sides of the first positioning groove. The positioning blocks are located on the boring tool main body. The first positioning groove is of a circular structure, and the second positioning groove is of a strip-shaped structure.

[0009] Preferably, the central threaded hole of the base is of a countersunk head structure. A groove for inserting the bolt head is provided at the port on the other side of the threaded hole, and a chamfer structure is provided at the edge of the groove opening.

[0010] Beneficial effects: Compared with the prior art, in the present utility model, the tool body is fixedly connected to the rotating shaft of the boring tool main body, and the high-pressure air inside the machine tool spindle is used to rotate the rotating shaft, thereby driving the tool body to rotate. When the tool body rotates, the cutting edge processes the housing, so as to achieve high-precision processing, reduce processing errors, improve product quality stability, and do not require frequent tool replacement. In this way, the processing time can be greatly shortened, the working hours are shortened by nearly 20 minutes, and the production efficiency is improved. Description of the Drawings

[0017] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0018] As Figures 1-5 shown, the boring tool main body 1, the rotating shaft 2, the tool body 3, the base 4, the tool tip 5, the first positioning groove 6, the second positioning groove 7, and the cutting edge 8;

[0019] A boring tool structure for housing track processing includes a boring tool main body 1 and a tool body 3. The tool body 3 includes a base 4. The base 4 is a cuboid structure. Tool tips 5 are provided at both ends of the base 4. The two tool tips 5 are symmetrically arranged with the center point of the base 4 as the reference. The tool tip 5 is a square structure, and its upper section is an inclined surface, and a cutting edge 8 is provided on the inclined surface. The center of the base 4 is fixedly connected to the rotating shaft 2. The rotating shaft 2 is rotatably connected inside the boring tool main body 1. The tool body 3 and the rotating shaft 2 are fixedly connected by bolts. A threaded hole is provided at the center of the base 4, and a threaded structure is provided on the inner side wall of the rotating shaft 2. The bolt sequentially passes through the threaded hole on the base 4 and the rotating shaft 2.

[0020] At the port of the central threaded hole of the base 4, there is a first positioning groove 6 for inserting the rotating shaft 2. On both sides of the first positioning groove 6, there are second positioning grooves 7 for inserting the positioning blocks. The positioning blocks are located on the boring tool body 1. The first positioning groove 6 is circular in structure, and the second positioning groove 7 is strip-shaped. The central threaded hole of the base 4 is a countersunk head structure. At the port on the other side of the threaded hole, there is a groove for inserting the bolt head, and the edge of the groove opening is provided with a chamfer structure.
