Abstract
The utility model relates to a center hole grinding centre which comprises a taper shank and a taper head. The center hole grinding centre is characterized in that the taper head is a hexahedron taper head, the taper angle of the taper head is 55 degrees to 65 degrees, the edges where two adjacent taper faces of the taper head are intersected are connected through connecting arcs, and the chord length of each connecting arc is 0.15mm to 0.3mm. The center hole grinding centre is simple in structure, easy to manufacture, low in cost and convenient to use and install, the arcs are used for connection, the run-out errors at the highest point of the longitudinal section of the center hole grinding centre are reduced, the locating accuracy is high, the circular degree, the roughness and the grinding efficiency of the locating taper face of a grinded center hole are improved, the grinding time and the grinding cost are saved, and the economical benefits are good.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of centre bore and grinds top.
Background technology
The grinding center hole is an operation commonly used in machining, and the Ginding process of centre bore has multiple, but is not that efficiency is low, is exactly that grinding precision is not high, can not reach the effect that the two is taken into account.Grind expense in order to reduce centre bore, this just need a kind of easy to operate, grinding efficiency and the high grinding of precision top.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, and the centre bore that provide a kind of simple in structure, easy to manufacture, easy to use, positioning precision is high grinds top.
Centre bore of the present utility model grinds top, comprises taper shank and conehead, and it is characterized in that: described conehead is the hexahedron conehead, and the cone angle of conehead is 55
0～65
0; The crossing seamed edge of adjacent two conical surfaces of described conehead connects by connecting circular arc.
In order better to realize above-mentioned purpose:
The chord length of described connection circular arc is 0.15～0.3 millimeter.
Top, simple in structure, the easy to manufacture expense of centre bore grinding of the present utility model is low, easy to install and use; The employing circular arc connects, and has reduced the runout error that grinds top longitudinal section peak, and positioning precision is high, has improved circularity, roughness and the grinding efficiency of grinding center hole orientational cone-shaped surface, has saved milling time and grinding expense, good in economic efficiency.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the E-E biopsy cavity marker devices zoomed-in view of Fig. 2.
In figure: 1, conehead; 2, taper shank; α, cone angle; R, connection circular arc; S, chord length.
The specific embodiment
The utility model centre bore grinds top, comprises taper shank 2 and conehead 1.Conehead 1 is the hexahedron conehead, and the cone angle of conehead 1 is 60
0; The crossing seamed edge of adjacent two conical surfaces of conehead 1 connects by connecting circular arc R, and the chord length S that connects circular arc R is 0.2 millimeter.
The carbide alloy manufacture that conehead 1 is ultra-fine by the K class.
It is to use like this that centre bore of the present utility model grinds top: top taper shank 2 of the present utility model is fixed on the base of jig, workpiece that again will the grinding center hole is fixed on lathe, adjust rotating speed, can start lathe the centre bore of workpiece is ground.
Claims (2)
1. a centre bore grinding is top, comprises taper shank (2) and conehead (1), and it is characterized in that: described conehead (1) is the hexahedron conehead, and the cone angle of conehead (1) is 55
