The height for stating the external cylindrical surface of throw-out collar matches, and the shape of shape and external cylindrical surface matches.
Preferably, the top side of the external cylindrical surface is arranged with a pair of of recessed portion.
Further, the throw-out collar both sides are equipped with to fix the throw-out collar briquetting and screw of throw-out collar, and the throw-out collar briquetting is stretched
Enter the recessed portion on the external cylindrical surface of the throw-out collar both sides, throw-out collar briquetting is fixed in throw-out collar fixed plate by screw.
Preferably, the diameter of the via is more than the diameter of the internal conical surface bottom, straight less than throw-out collar external cylindrical surface
Footpath.
Further, the throw-out collar briquetting stretches into the shape of the recessed portion and is engaged with the shape of the recessed portion.
Preferably, the craft thread hole is located on throw-out collar bottom end face.
Further, the craft thread hole is located at the bottom of the internal conical surface of the throw-out collar and same with the internal conical surface
Axis.
Advantageous effect：
The utility model is stretched by throw-out collar briquetting in the recessed portion on throw-out collar external cylindrical surface, then with screw by throw-out collar briquetting
Locked and fixed can have the function that fixed and position throw-out collar in the pit of throw-out collar briquetting；On the end face of throw-out collar bottom to
Interior setting craft thread hole, it is convenient on numerically-controlled machine tool with frock tool by clamped one time, once complete processing internal conical surface,
Outer conical surface and external cylindrical surface avoid three face concentricities superpositions that secondary clamping brings, ensure that positioning progress and
The quality of machining accuracy and product；Throw-out collar structure also from the small structure broad in the middle in both ends, is improved to the big structure in the small one end in one end,
By the cooperation of via, facilitate clamped one time, complete the processing in all faces, it is time saving and energy saving；The utility model can make clamping
Frock volume reduces, and using small dimension equipment, also saves raw material, more cost-effective.To sum up, the utility model at least has
It is simple in structure, only need clamped one time that can process all faces, easy to maintenance, production and processing is at low cost, endoporus and outer circle it is concentric
The advantages that degree can be guaranteed, high precision machining.
