Abstract
The utility model discloses an assembled compound cutting tool. Wherein different cutters are combined on the cutter hub by assembling; the large hole cutter is pressed on the corresponding shaft shoulder on the upper part of the cutter hub by its inner hole and internal thread; and the small hole cutter is mounted in the taper hole on the lower part of the cutter hub by its taper shank. The assembled compound cutting tool has the following advantages: all the cutters can be replaced, thereby can be fully utilized; and the cutter hub can be used repeatedly, thereby the manufacturing cost of the cutting tool is reduced.
Description
Technical field
The utility model relates to the process tool of machine components, especially the compound cutter of the assembling of machining hole.
Background technology
The different shoulder hole of size is arranged on the same axis of some machine components, and general macropore is last, and aperture is following.In order to improve working (machining) efficiency, a feed of ladder cutter processing macropore and apertures of adapting of employing and macropore and aperture all.Just adopt several thick, fine finishining of the ladder cutter being finished valve seat orifice and guide hole respectively as the valve seat orifice of 16V240 cylinder head and the processing of guide hole.All used whole ladder cutter in the past, one-level cutter wearing and tearing or damage are wholely just scrapped cutter, cause waste.
Summary of the invention
The purpose of this utility model provides the compound cutter of a kind of assembling, replaces whole ladder cutter.
The technical scheme that its technical problem that solves the utility model adopts is: the method for cuttves at different levels with assembling is combined on the cutter hub.
Assemble compound cutter and form, it is characterized in that by cutter hub, macropore cutter and aperture cutter: the macropore cutter by it endoporus and internal thread be pressed in the cutter hub top the corresponding shaft shoulder on, the aperture cutter is contained in the taper hole of cutter hub bottom with its taper shank.
This advantage of assembling compound cutter is: cuttves at different levels can be changed, and every grade of cutter can both be made full use of.Cutter hub is reused, and saves the cutter manufacturing cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is the installation diagram of the compound cutter of assembling.
Fig. 1 is a front view, is the A-A cutaway view of Fig. 2.
The upward view of Fig. 2 Fig. 1.
1. cutter hubs among the figure, 2. macropore cutter, 3. aperture cutter.
The specific embodiment
Accompanying drawing is the compound cutter of assembling that processing 16V240 cylinder cover for diesel engine valve seat orifice and guide hole are used.In the accompanying drawings, macropore cutter (2) is pressed on the corresponding shaft shoulder of cutter hub (1) top by its endoporus and internal thread, and it is H7/h6 that the endoporus of macropore cutter (2) cooperates with the corresponding cylinder of cutter hub (1).Aperture cutter (3) is contained in the following taper hole of cutter hub (1) with its taper shank.The afterbody of cutter hub (1) is general cutter Morse taper shank.The afterbody of aperture cutter (3) is than the little cutter Morse taper shank of cutter hub (1) afterbody.In order to guarantee to assemble the positional precision of compound each blade of cutter of back assembling, the Morse taper shank of cutter hub (1) is 0.01 millimeter of φ with the axiality tolerance in the hole that aperture cutter (3) Morse taper shank is installed.Each blade of macropore cutter (2) is 0.02 millimeter to the run-out tolerance of its interior axially bored line.Each blade of aperture cutter (3) is 0.01 millimeter to the run-out tolerance of its Morse taper shank axis.When processing 16V240 cylinder cover for diesel engine valve seat orifice and guide hole, respectively with thick, half smart and smart three kinds of compound cuttves of assembling.
Claims (4)
