Summary of the invention
The purpose of the utility model is to provide a kind of can protect rotating shaft in whole rotor manufacture process, and can add the machine shaft cylindrical clamp for machining that prevents that rotating shaft from being crushed man-hour in turning.
In order to achieve the above object; The technical scheme that the utility model adopts is; A kind of machine shaft cylindrical clamp for machining; And its: comprise the cylinder axis body, have and being used for and the accurate equipped frustum spindle nose of work piece machine shaft axle head centre bore of cylinder axis body concentric arrangement at an end face of cylinder axis body; Outside the center line of cylinder axis body, be with at least 2 arrange vertically be used for work piece machine shaft axle head set be connected the through hole that screw matches; The cylinder axis body with respect to the other end that frustum spindle nose end face is arranged, be provided with the top equipped mutually frustum counterbore with machining tool tailstock centralized positioning axle of being used for cylinder axis body concentric arrangement.
In above-mentioned technical scheme, said through hole has 4, and said 4 through holes are along evenly arranged apart with the circular arc line of the same radius in cylinder axis body center.
In above-mentioned technical scheme, the cylinder axis body with respect to the other end that frustum spindle nose end is arranged, also be provided with and be used for and carry the screw that suspender is connected.
In above-mentioned technical scheme, said screw and frustum counterbore concentric arrangement, and be positioned at the bottom of said frustum counterbore.
The beneficial effect of the utility model is: because after adopting above-mentioned anchor clamps; During use; Respectively that the frustum spindle nose and the said machine shaft two axial ends centre bore of one or two the utility model is accurate equipped; The axially extending bore of the utility model is threaded with the screw that is connected of machine shaft axle head through securing member, thereby one or two the utility model and said rotating shaft are linked into an integrated entity.In turning process; Because the utility model of said rotating shaft one end is blocked by lathe chuck; And the centre bore of the utility model of its other end or rotating shaft is top equipped mutually with the lathe tailstock centralized positioning; And prevent that effectively the axle head of said rotating shaft and significant points from being crushed, play the effect of protection rotating shaft.
Description of drawings
Fig. 1 is that the master of a kind of specific embodiment of the utility model looks cross-sectional view;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the user mode reference diagram of the utility model, and wherein, 2 is that the tailstock centralized positioning is top, and 3 is chuck, and 4 is machine shaft.
The specific embodiment
Below in conjunction with accompanying drawing and the embodiment that provides, the utility model is described further, but is not limited to this.
Like Fig. 1, shown in 2, a kind of machine shaft cylindrical clamp for machining comprises cylinder axis body 1, has and being used for and the accurate equipped frustum spindle nose 1-1 of work piece machine shaft axle head centre bore of cylinder axis body 1 concentric arrangement at an end face of cylinder axis body 1; Outside the center line of cylinder axis body 1, be with at least 2 arrange vertically be used for work piece machine shaft axle head set be connected the through hole 1-2 that screw matches; Cylinder axis body 1 with respect to the other end that frustum spindle nose 1-1 end face is arranged, be provided with and being used for and top 2 of machining tool tailstock centralized positioning axle equipped mutually frustum counterbore 1-3 of cylinder axis body 1 concentric arrangement.
As shown in Figure 2, for the fastness that guarantees that the utility model is connected with rotating shaft 4, said through hole 1-2 has 4, and said 4 through hole 1-2 are along evenly arranged apart with the circular arc line of the same radius in cylinder axis body 1 center.
Like Fig. 1,2, shown in 3, the carrying of said machine shaft for ease, cylinder axis body 1 with respect to the other end that frustum spindle nose 1-1 end is arranged, also be provided with and be used for and carry the screw 1-4 that suspender is connected.
