The utility model comprises a guide head with one conical end, wherein the guide head is coaxially connected with a connecting rod, and a chip groove is arranged at the connecting position of the guide head and the connecting rod; the top of the connecting rod is provided with two cutter head mounting surfaces which are centrosymmetric around the axis, and the cutter head mounting surfaces are connected with square cutting cutter heads; the bottom of the connecting rod is connected with a connecting knife handle. The utility model can ensure that the coaxiality of the processed valve hole and the counter bore of the valve hole meets the design requirement, and the cutting tool bit is made of tungsten steel, thereby having longer service life and higher stability.
Description
Technical Field
The utility model belongs to the technical field of hub machining, and particularly relates to a cutter for drilling a counter bore of a valve hole of a hub.
Background
The cutter for drilling and processing the traditional wheel hub valve hole counter bore adopts when drilling the valve hole, a tool, a workpiece is fixed, a hook cutter is used again to pass the valve hole for reverse boring, because the difference in counter bore diameter, the valve hole diameter is different, therefore, the limitation is very strong when the hook cutter is eccentric in calculation, because the counter bore diameter size is by valve hole size, eccentric size, comprehensive decisions such as equipment precision, make the counter bore diameter size not control well, finally lead to the quality after the wheel hub processing unstable, thereby produce the influence to the wholeness ability after the automobile assembly.
Disclosure of Invention
In order to make up for the defects of the prior art, the utility model provides the cutter for drilling the wheel hub valve hole counter bore, and the machined valve hole and the valve hole counter bore can meet the design requirements.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
a cutter for drilling and processing a counter bore of a valve hole of a hub comprises a guide head, wherein one end of the guide head is conical, and the other end of the guide head is cylindrical; the cylindrical end of the guide head is coaxially and fixedly connected with a connecting rod, the diameter of the connecting rod is 2 times of that of the cylindrical end of the guide head, and a chip removal groove is formed in the connecting position of the cylindrical end of the guide head and the connecting rod; the top of the connecting rod is provided with two cutter head mounting surfaces which are centrosymmetric around the axis, the cutter head mounting surfaces are fixedly connected with cutting cutter heads, and the cutting cutter heads are square sheets; the bottom of the connecting rod is fixedly connected with a connecting knife handle, and the diameter of the connecting knife handle is 0.9 times of that of the connecting rod;
specifically, the cutting bit is welded to the connecting rod.
The utility model has the beneficial effects that:
1) the utility model can ensure that the coaxiality of the processed valve hole and the valve hole counter bore meets the design requirement;
2) the cutting tool bit is made of tungsten steel, so that the cutting tool bit has longer service life and higher stability when being used for machining an aluminum alloy hub;
3) the guide part adopts the conical surface, so that the valve guide device is suitable for valve apertures with different sizes, the tool changing time is saved, and the productivity is improved;
4) the utility model can directly process on the working surface when the reverse processing is carried out, thereby reducing the rejection rate of blind processing.

Detailed Description
The present invention will be described in detail with reference to specific embodiments.
Fig. 1 is a schematic view of the overall structure of the present invention. As shown in figure 1, the utility model comprises a guide head 1, wherein one end of the guide head 1 is conical, and the other end of the guide head 1 is cylindrical; the cylindrical end of the guide head 1 is coaxially and fixedly connected with the connecting rod 3, the diameter of the connecting rod 3 is 2 times of that of the cylindrical end of the guide head 1, and a chip removal groove is formed in the connecting position of the cylindrical end of the guide head 1 and the connecting rod 3;
the top of the connecting rod 3 is provided with two cutter head mounting surfaces which are centrosymmetric around the axis, the cutter head mounting surfaces are fixedly connected with cutting cutter heads 2 through welding, and the cutting cutter heads 2 are square sheets; in this embodiment, cutting tool bit 2 chooses the tungsten steel material for use, when processing aluminum alloy wheel hub, has higher life-span and stability. The cutting insert 2 forms a cutting outer diameter of a product required size when rotating.
The tungsten steel belongs to hard alloy, which is called as tungsten titanium alloy, the hardness can reach 89-95 HRA, and the tungsten steel is not easy to wear; the high-hardness wear-resistant steel has a series of excellent performances of high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and the like, particularly high hardness and wear resistance, basically keeps unchanged even at the temperature of 500 ℃, and still has high hardness at the temperature of 1000 ℃. Tungsten steel is commonly used as a high-precision machining and high-precision cutter material.
The bottom of the connecting rod 3 is fixedly connected with a connecting handle 4, and the diameter of the connecting handle 4 is 0.9 times of that of the connecting rod 3.
When the connecting tool is used, the connecting tool handle is clamped on a machine tool, the panel turnover machine is turned over by 180 degrees after the valve hole is machined by an automatic numerical control machining program, the counter bore of the valve hole is drilled and machined directly through the guide head according to a program instruction, the valve hole and the counter bore of the valve hole can be ensured to be coaxial, and tool changing machining is not required when the size of the valve hole changes.
In the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "mounted," "connected," and "secured" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integral to; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The utility model is not limited to the examples, and any equivalent changes to the technical solution of the utility model by a person skilled in the art after reading the description of the utility model are covered by the claims of the utility model.
