Background
A tool is a tool used for cutting machining in machine manufacturing, and is also called a cutting tool. Most knives are machine, but also hand-held. Since tools used in machine manufacturing are basically used for cutting metal materials, the term "tool" is generally understood to mean a metal cutting tool. The cutting tools for cutting wood are called woodworking tools. There is also a class of tools of particular application for geological exploration, well drilling, mine drilling, known as mine tools.
In general, the end of a pipe or a hole needs to be chamfered in the machining process, so that burrs generated by machining on parts are removed, and the parts are convenient to assemble. The chamfering tool is generally of a cone shape, and a plurality of blades perpendicular to the rotating direction are arranged on the cone surface of the chamfering tool, so that cutting processing is performed during rotation. But current chamfer cutter is at the during operation, and is usually fixed workpiece and tool bit respectively, then processes, does not have interconnect between this moment tool bit and the work piece, the vibration probably appears in the machining process, and tool bit and work piece can relative movement, have just so caused machining error, are unfavorable for improving machining precision, have also reduced the yields.
SUMMERY OF THE UTILITY MODEL
Not enough to exist among the prior art, the utility model provides a high accuracy chamfer cutter for solve among the prior art chamfer cutter add man-hour machined part and tool bit fixed respectively, when leading to the circumstances such as vibration appearing in the course of working, tool bit and work piece can relative movement, lead to the machining precision to be influenced, the problem of substandard product still can appear.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a high-precision chamfering tool comprises a tool bit and an installation section, wherein the tool bit and the installation section are connected in a front-back mode, the installation section is in a hollow cylindrical shape, and a connecting mechanism is arranged in the middle of the installation section; the tool bit and the mounting section are coaxially arranged, a hollow part is arranged in the tool bit, the end face of the tool bit, which is far away from one end of the mounting section, is of an inwards-concave conical shape, and a plurality of blades are uniformly arranged on the end face of the tool bit along the radial direction; the connecting mechanism is detachably connected with a core rod at one end close to the cutter head, one end of the core rod is fixedly connected to the connecting mechanism, the other end of the core rod extends out of the cutter head, the diameter of the core rod is smaller than the inner diameters of the mounting section and the cutter head, and the connecting mechanism can allow the core rod to freely rotate along the axial direction.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses be provided with can be at the inside free rotation's of installation section and tool bit plug, and the diameter of plug cooperatees with the internal diameter of the pipe fitting of processing, make the pipe fitting can the cover establish outside the plug, the plug forms a whole with the pipe fitting this moment, the position of the relative tool bit of pipe fitting obtains fixing promptly, in the course of working, even appear rocking the condition of vibration, the pipe fitting also removes with the tool bit integral type, and relative displacement can not take place, the accuracy nature in the chamfer course of working has just so been guaranteed, thereby the machining precision is improved, the quality of processing back pipe fitting has been guaranteed.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: the tool bit comprises a tool bit 1, an installation section 2, a core rod 3, a fixed disc 4, a connecting screw rod 5, a bearing 6 and a locking ring 7.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.
Example (b):
as shown in fig. 1, the utility model provides a high accuracy chamfer cutter, connect tool bit 1 and the erection segment 2 that sets up including the front and back, erection segment 2 is the cavity drum type, and the intermediate position is provided with coupling mechanism in the erection segment 2, and both ends then are connected with the output of tool bit 1 and motor respectively to provide power to tool bit 1 part.
The connecting mechanism is detachably connected with a core rod 3 at one end close to the tool bit 1, one end of the core rod 3 is fixedly connected to the connecting mechanism, the other end of the core rod extends out of the tool bit 1, the diameter of the core rod 3 is smaller than the inner diameters of the installation section 2 and the tool bit 1, and the connecting mechanism can allow the core rod 3 to freely rotate along the axial direction. The diameter of plug 3 cooperatees with the internal diameter of the pipe fitting of processing for the pipe fitting can overlap and establish in 3 outsides of plug, and plug 3 forms a whole with the pipe fitting this moment, and the position of the relative tool bit 1 of pipe fitting is fixed promptly, in the course of working, even appear rocking the condition of vibration, the pipe fitting also removes with 1 integral type of tool bit, and relative displacement can not take place, has just so guaranteed the accuracy nature in the chamfer course of working.
