At present, especially in the crankshaft machining industry, special equipment or a mechanical arm is usually needed to clamp a profiling tool, the size and the position of burrs are sensed through force feedback to remove the burrs, and the machining cost and the tool consumption are high.

The above background disclosure is only provided to aid in understanding the concepts and technical solutions of the present invention, and it does not necessarily belong to the prior art of the present patent application, and it should not be used to assess the novelty and inventive step of the present application without explicit evidence that the above content has been disclosed at the filing date of the present patent application.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve present bent axle processing burr and get rid of the problem of existence, provide a burring cutter. This cutter need not additionally purchase processing equipment or artifical the getting rid of to the cutter form is installed on digit control machine tool, can all effectively get rid of the burr after the processing of various holes, makes the work piece of being processed can not participate in lubricated life-span that influences the product because the burr drops.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a deburring cutter comprises a cutter head, a swing rod and a cutter handle; the tool bit and the tool handle are connected by a swing rod, the tool bit, the swing rod and the tool handle are integrally communicated and are positioned on the same middle shaft, and a cooling liquid interface is arranged at the outer end of the tool handle; the cutter head is provided with a central cold hole, and the outer port of the central cold hole is sealed; the head of the cutter head is a cutter head with cutting edges, the cutting edges are distributed along the circumferential direction, an incomplete circumference is formed by cutting off parts in the circumferential direction, and 1-5 pressure relief holes are drilled in the side surfaces of the cutting off. The pressure relief hole plays a role in pressure relief, and the cutter is pushed to be tightly attached to the hole wall by hydraulic pressure, so that the burrs are subjected to back chipping and cutting.

Preferably, the tool bit, the swing rod and the tool handle are connected in an integrated or split mode.

Preferably, the materials of the tool bit, the swing rod and the tool holder can be high-speed steel, cobalt-containing high-speed steel and powder metallurgy according to different processing materials; preferably cemented carbide.

Preferably, the tool bit, the swing rod and the tool handle are of hollow tube structures.

Preferably, the diameter of the pendulum rod is smaller than the diameter of the cutter head and the diameter of the cutter handle.

Preferably, the number of the pressure relief holes is 1-5.

Compared with the prior art, the utility model discloses an advantage and beneficial effect do:

the utility model provides a special cutter of burring does not need additionally to purchase processing equipment or artifical the getting rid of, and it can be installed on the digit control machine tool with the cutter form. After the cutter is installed, a hydraulic device is started, and due to the fact that a cooling hole is sealed in the center of the reamer-shaped head, liquid can be decompressed from a pressure relief hole in the eccentric surface of the reamer, the liquid is beaten on the hole wall to form thrust to push the cutter head to be attached to the hole wall, the burr root is attached to the edge of a cutter head during rotation to thoroughly remove burrs, secondary burrs cannot be formed, and the improvement of the surface smoothness of a processed part is facilitated. The tool is simple in structure, simple in application condition, high in machining efficiency, long in service life, capable of greatly saving labor and low in equipment cost, and has good market application prospect, and an effective way is improved for modern high-precision machining.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.

As shown in attached figures 1-5, the deburring cutter comprises a cutter head 1, a swing rod 2 and a cutter handle 3; the tool bit 1 and the tool shank 3 are connected through the swing rod 2, the tool bit 1, the swing rod 2 and the tool shank 3 are integrally communicated and connected into a whole and are positioned on the same middle shaft, and a cooling liquid interface is arranged at the outer end of the tool shank 3; a central cold hole 5 is formed in the cutter head 1, and the outer port of the central cold hole 5 is sealed; the head of tool bit 1 is the cutter head of taking the cutting edge, the cutting edge distributes along the circumferencial direction, and the circumferencial direction excision part forms incomplete circumference, and is equipped with 2 pressure release holes 4 in the excision side. The tool bit 1, the swing rod 2 and the tool shank 3 are made of hard alloy. The tool bit 1, the swing rod 2 and the tool handle 3 are of hollow tube structures. The diameter of the swing rod 2 is smaller than that of the tool bit 1 and the tool handle 3.

The working principle is as follows: will this practical burring cutter installs on digit control machine tool, and the back is installed to the cutter, squeezes into the coolant liquid from the handle of a knife, because the sealing in the central cold hole, the pressure release hole blowout of reamer eccentric plane can be followed to liquid, and liquid is beaten at the pore wall and is formed thrust, promotes the cutter head and hugs closely the pore wall, and burr root thoroughly excises the burr can be hugged closely to the tool bit cutting part during rotation, can not form secondary burr, and cutter cutting part excises the burr.

While there has been described and illustrated what are considered to be example embodiments of the present invention, it will be understood by those skilled in the art that various changes and substitutions can be made therein without departing from the spirit of the invention. In addition, many modifications may be made to adapt a particular situation to the teachings of the present invention without departing from the central concept described herein.
