Abstract
The invention discloses a plug matched with the end part of a shaft to be ground. Both ends of the shaft to be ground are respectively provided with a shaft center hole; and an internal thread is arranged in the shaft center hole. The plug comprises a conical surface, a stud and a cylinder, wherein the conical surface comprises a front end surface and a back end surface, and the diameter of the front end surface is smaller than that of the back end surface; the stud is coaxially connected with the front end surface; the cylinder is coaxially connected with the back end surface; and the other end of the cylinder is provided with a plug center hole. The plug matched with the end part of a shaft to be ground has the advantages of short manufacturing time, small size and compact structure, and is convenient for mounting and dismounting. Further, the plug effectively prevents the center hole deformation caused by frictional heat from influencing the external grinding precision due to the long machining time in the grinding machining process of shaft workpieces made of soft materials, long-shaft workpieces and high-precision high-weight shaft workpieces, thereby enhancing the machining precision of the shaft.
Description
Technical field
The present invention relates to be used for device that shaft-like workpiece is fixed and processed, particularly a kind of plug that is used for the heavier shaft-like workpiece of grinding soft material, major axis or weight.
Background technology
In cylindricalo grinding, centre bore is the benchmark of axial workpiece grinding, because the material difference of axle, structure is different, and the variation of centre bore in grinding is also different, soft material particularly, the required precision height, the elongated and heavier axle class of weight, bowlder outside grinding, time is longer relatively, very easily causes the centre bore distortion because of frictional heating because centre bore is worked over a long time often.Therefore, the cooling and lubricating of centre bore is the major issue that cylindricalo grinding need be considered.Usually adopt installation shaft in grinding machine forward and backward top before, the axle centre bore injects butter, the grinding overlong time then central hole annotate machine oil help cooling and lubricating and repeatedly loading and unloading spool its cooling is solved, thereby this operating efficiency be greatly affected and increase the back work amount.
General more important axle all will reach the requirement of degree of precision and low roughness through the grinding cylindrical, and in grinding, centre bore is the benchmark of working shaft-like part, and the grinding cylindrical has significant effects to its precision height to processing particularly.In real work, identical workpiece finish grindes cylindrical by same operator on same grinding machine, and often owing to the difference of centre bore precision, the workpiece accuracy that grinds is widely different, draws the importance of precision in Precision Machining of centre bore thus.Axial workpiece generally all passes through heat treatment quenching and tempering, but after modified, the hardness at center is the hardness well below cylindrical, this for the grinding time grow (than farm labourer's part), grinding accuracy is higher and weight is heavier axle, just easily make centre bore frictional heating generative center bore deformation, lose original precision, and have influence on the grinding of cylindrical.For the cylindricalo grinding of the axle of soft material, this problem is just more outstanding.
Summary of the invention
The technical problem to be solved in the present invention, be for overcome in the prior art for than the softer shaft-like workpiece of long-axle workpieces and material in the process of cylindricalo grinding, be easy to generate the centre bore distortion, the defective of influence axle machining accuracy provides a kind of and to be ground adaptive plug in end.
The present invention solves above-mentioned technical problem by following technical proposals:
The adaptive plug in end of axle a kind of and to be ground, the two ends of this axle to be ground are equipped with a centre bore, be provided with internal thread in this centre bore, its characteristics are, this plug comprises a conical surface, this conical surface comprises a front end face and a rear end face, and wherein the diameter of this front end face is less than the diameter of this rear end face; One is connected with this front end face and the double-screw bolt of coaxial setting; And one be connected with this rear end face and the cylinder of coaxial setting, and the other end of this cylinder is provided with a plug centre bore.
Preferably, this plug centre bore is a Type B centre bore.
Preferably, described axle centre bore is a C type centre bore; The central angle of this conical surface of this plug is 60 °.
Preferably, structural carbon steel behind this plug employing heat treatment quenching and tempering or the structural alloy steel behind the heat treatment quenching and tempering are made.
Preferably, the outer surface of this cylinder is provided with two relative dismounting planes.
Preferably, the external diameter of this double-screw bolt is identical with the diameter of this front end face; The diameter of this cylinder is identical with the diameter of this rear end face.
Among the present invention, above-mentioned optimum condition can make up arbitrarily on the basis that meets this area general knowledge, promptly gets the preferred embodiments of the invention.
Positive progressive effect of the present invention is: the plug that is used for a cylindricalo grinding among the present invention, and short during worker, and volume is little, compact conformation, and easy to loading and unloading.Further, eliminated the shaft-like work that adopts soft material to make effectively, than long axis workpiece and precision is higher relatively, weight is heavier shaft-like workpiece at Grinding Process frictional heating generative center bore deformation, influence the generation of the situation of cylindricalo grinding precision, improved the accuracy of axle processing.
