The boring cutter for machining the inner bore of the automobile engine comprises a cutter handle and a cutter body. The cutter body is fixedly mounted at one end of the cutter handle, a cutter blade is fixedly mounted on the cutter body, a tool cutting edge angle alpha is arranged at a cutter bit of the cutter blade, the alpha is larger than or equal to 1 degree and smaller than or equal to 2 degrees, an arc-shaped groove is formed in the position which is h away from the other end of the cutter handle, h is larger than or equal to 5.5 mm and smaller than or equal to 6 mm, the arc diameter of the arc-shaped groove is 2 mm, the connecting position between the cutter body and the cutter handle is provided with an inclined plane, the included angle beta between the inclined plane and the horizontal line is larger than or equal to 40 degrees and smaller than or equal to 45 degrees. The boring cutter for machining the inner bore of the automobile engine is stable in clamping of the cutter handle, the service life of the cutter is prolonged effectively, and machining quality is improved.
Description
Technical field
The utility model relates to a kind of boring cutter, particularly relates to a kind of boring cutter for processing automobile engine endoporus.
Background technology
Automobile engine endoporus is being added to man-hour, the handle of a knife of existing boring cutter is generally cylindric, there will be unstable, easy loosening situation, and cutter is in the process that workpiece is processed when handle of a knife clamping, can cause scratch to workpiece, cutter life is short, and durability is low, causes frequent replacing cutter, not only increase production cost, and inefficiency, cause the crudy of workpiece bad, affect the surface quality of workpiece.
Summary of the invention
The utility model, in order addressing the above problem, to provide a kind of the service life of cutter and the boring cutter for processing automobile engine endoporus of raising crudy have been stablized, effectively extended to handle of a knife clamping.
The technical solution of the utility model is:
A kind of boring cutter for processing automobile engine endoporus, comprise handle of a knife and cutter hub, described cutter hub is fixedly mounted on one end of handle of a knife, on cutter hub, be installed with blade, the cutter head place of described blade is provided with tool cutting edge angle α, and 1 °≤α≤2 ° is being that h place is provided with circular groove apart from the handle of a knife other end, and 5.5mm≤h≤6mm.
The arc diameter of described circular groove is 2mm.
Described cutter hub and handle of a knife junction are provided with an inclined plane, and described inclined plane and horizontal angle are β, and 40 °≤β≤45 °.
The material of described blade is polycrystalline diamond.
The material of described cutter hub is carbide alloy.
Useful good effect of the present utility model is:
The utility model is provided with tool cutting edge angle α at the cutter head place of blade, and tool cutting edge angle is too little, relatively easily causes vibrations, is mainly applicable to the workpiece that hardness is high; If tool cutting edge angle is too large, the durability of cutter is low, the utility model is located at the scope of tool cutting edge angle α between 1 ° ~ 2 °, cutter is difficult for damaged, extends the service life of cutter, and increase apart from afterbody 5mm place the circular groove that diameter is 2mm at handle of a knife, can indirectly strengthen the stability of cutter clamping, reduce because tool damage causes frequent replacing cutter, reduce production cost, increase work efficiency.
