At present, the axle center place that the broaching tool with flat overlaps has a circular hole vertically, and this circular hole is used for installing broaching tool. Existing structure has the drawback that: rotates in the broaching tool easily circular hole on the broaching tool with flat overlaps, thus it cannot be guaranteed that the circumferential position that overlap relative to the broaching tool with flat of broaching tool, is badly in need of the above-mentioned technical barrier of solution for this.
Utility model content
Technical problem to be solved in the utility model is in that to provide a kind of broaching tool set with flat, is intended to ensure the circumferential position that broaching tool overlaps relative to the broaching tool with flat.
The technical solution of the utility model is as follows: a kind of broaching tool set with flat, including the first cylindrical section (1) and the 3rd cylindrical section (4), wherein the first cylindrical section (1) right-hand member is connected with the second cylindrical section (3) left end by planar section (2), this the second cylindrical section right-hand member is connected with described 3rd cylindrical section (4), and the axial line of first, second and third cylindrical section (1,3,4) and planar section (2) is on same straight line; The equal diameters of described first and second cylindrical section (1,3), and more than the diameter of the 3rd cylindrical section (4), it is formed with a breach for installing broaching tool clamp between first and second cylindrical section (1,3), and the right-hand member of the 3rd cylindrical section (4) is provided with guiding taper seat; The axial line place of described first, second and third cylindrical section (1,3,4) and planar section (2) has a broaching tool installing hole (5), this broaching tool installing hole is through hole, it is characterized in that: the whole hole wall of described broaching tool installing hole (5) is milled with a flat horizontal surface (5a), the roughness��0.8mm of this flat horizontal surface vertically; The outer wall of described first cylindrical section (1), planar section (2) and the second cylindrical section (3) is milled with one vertically to cutter flat horizontal surface (6), this is parallel with described flat horizontal surface (5a) to cutter flat horizontal surface, and this two flat horizontal surface is positioned at the same side of the first cylindrical section (1) axial line.
This utility model is on the basis of traditional structure, and the whole hole wall of described broaching tool installing hole (5) is milled with a flat horizontal surface (5a), the roughness��0.8mm of this flat horizontal surface vertically;The outer wall of described first cylindrical section (1), planar section (2) and the second cylindrical section (3) is milled with one vertically to cutter flat horizontal surface (6), this is parallel with described flat horizontal surface (5a) to cutter flat horizontal surface, and this two flat horizontal surface is positioned at the same side of the first cylindrical section (1) axial line.
Adopt above technical scheme, this utility model is by positioning cutter flat horizontal surface, install this broaching tool set, thus it is easy to cutter and centering, and it is by the flat horizontal surface of broaching tool installing hole, broaching tool circumference is spacing, thus ensureing the circumferential position that broaching tool overlaps relative to broaching tool, and then overcome the defect of existing structure well.
As preferably, the roughness of described flat horizontal surface (5a) is 0.8mm, thus can reduce the abrasion of broaching tool further, thus improving serviceability of the present utility model further.
In the present case, the external diameter of described first cylindrical section (1) is 60mm, and the diameter of described 3rd cylindrical section (4) is 42mm.
Beneficial effect: this utility model is by positioning cutter flat horizontal surface, install this broaching tool set, thus it is easy to cutter and centering, and it is by the flat horizontal surface of broaching tool installing hole, broaching tool circumference is spacing, thus ensureing the circumferential position that broaching tool overlaps relative to broaching tool, and then overcome the defect of existing structure well.
