Description
Technical Field
The utility model relates to a device, especially a hinge taper hole chamfer integrated into one piece device of taper hole that processing needs the chamfer.
Background
At present, when a taper hole needing chamfering is machined, a composite cutter mode can be adopted for machining, and a reaming taper hole chamfering composite cutter is usually used for cutter selection.
The reaming taper hole chamfering compound cutter is characterized in that a countersink is arranged behind a taper reamer, and the angle of a tool cutting edge of the countersink is ground by adopting a tool grinder. However, the taper reamer and the countersink combined cutter have the following defects:
1. the taper reamer and the counter bit are non-standard cutters, need to be customized, and have a small application range;
2. when the countersink drill is used for grinding, each cutting edge angle needs to be accurately ground, so that the efficiency is low;
3. after the cutting edge of the countersink drill is worn, the cutter cannot be replaced quickly;
4. after the cutting edge of the countersink drill is abraded, regrinding is needed, and after the regrinding times are exceeded, the cutter is scrapped integrally, so that the cutter cost is high.
Disclosure of Invention
The utility model discloses aim at: providing a reaming conical hole and chamfer angle integrated forming device; the device adopts the clamp type assembly between each part blade holder, the cutter arbor, rhombus blade and the tapering reamer, can realize that blade processing is unified, guarantees that the size is unanimous, realizes the quick replacement of blade, improves blade holder and cutter arbor utilization ratio, reduces the cutter cost.
The technical scheme for solving the problems is as follows: a reaming conical hole and chamfering integrated forming device comprises a tool apron, a tool bar, a diamond-shaped blade and a tapered reamer;
in the installation state, the rhombic blade is installed on the cutter bar, positioned by the blade installation groove on the cutter bar and tightly pressed by tightening the riveting screw;
the cutter bar and the rhombic blade are integrated and are arranged on the cutter holder and are positioned and clamped through an inner hexagonal cylindrical end fastening screw I positioned on the right side of the cutter holder and an inner hexagonal cylindrical end fastening screw II positioned on the rear side of the cutter holder;
the cutter bar, the rhombic blades and the cutter holder are integrally arranged on the taper reamer cutter bar and are positioned and clamped through the inner hexagonal socket head cap screws.
The further technical scheme is as follows: an included angle alpha between the right cutting edge of the rhombic blade and the vertical plane of the cutter bar is 45 degrees; after assembly, the included angle beta between the main cutting edge of the rhombic blade and the horizontal plane is 45 degrees.
Therefore, the utility model relates to a hinge taper hole and chamfer integrated into one piece device has following beneficial effect:
the cutter holders, the cutter bars, the diamond blades and the taper reamers which form the integral reaming taper hole and chamfer forming device of the utility model are assembled in a clamping manner, so that the integral reaming taper hole and chamfer forming device can be realized;
1) the blades are machined uniformly, the consistent size is ensured, and the quality of the machined product is improved;
2) the blade can be quickly replaced, and the working efficiency is improved;
3) the tool apron and the tool bar can be repeatedly used, and the cost of the tool is reduced.
Secondly, because of adopting the special installation mode and cutter angle, can guarantee the product machining precision, workable taper hole chamfer is C0.5-C3, and size precision can reach GB/T1804-m level, and chamfer roughness is not less than 6.3 mu m, has guaranteed the product quality of being processed.
Thirdly, because blade holder 5 is fretwork shape, make the iron fillings of processing discharge from the fretwork department of blade holder 5, do not influence processing speed and can guarantee processingquality better.

Detailed Description
A hinge taper hole and chamfer integrated into one piece device:
as shown in fig. 1, the reaming taper hole and chamfer angle integrated forming device comprises a tool holder 5, a tool bar 4, a diamond-shaped blade 2 and a taper reamer 8;
the cutter holder 5 is hollow, one side of the cutter holder is provided with an opening, and screw holes are formed in the back side and one side of the cutter holder 5;
in the installation state, the rhombic blade 2 is installed on the cutter bar 4, positioned by a blade installation groove on the cutter bar and tightly pressed by tightening the riveting screw 3;
the cutter bar 4 and the rhombic blade 2 are integrally arranged on the cutter holder 5 and are positioned and clamped through an inner hexagonal cylindrical end fastening screw I6 positioned on the right side of the cutter holder 5 and an inner hexagonal cylindrical end fastening screw II 7 positioned on the rear side of the cutter holder 5;
