Be threaded owing to adopting, frock each several part convenient disassembly, can realize the quick dispatch of frock, uses very convenient.It has design science, precision is high, cost is low advantage.
Use this frock to process the processing technology of Bundy tube roll cylindrical groove, comprise the following steps:
1., by the first counterpart be installed on the chuck of lathe, and make shaft shoulder end face laminating chuck end face, ensure the coaxiality error of the first counterpart and machine tool chief axis;
2., the conical hole of the second counterpart is inserted on the conical surface axle of the first counterpart, the binding thread end of the first counterpart screws in the screwed hole of the second counterpart, tentatively fix, to ensure the described outer circumference surface of the second counterpart and the coaxiality error of machine tool chief axis;
3., roll workpiece is enclosed within the outer circumference surface of the second counterpart, the end face of the inner of this roll workpiece laminating shaft shoulder is ensured the error of perpendicularity of workpiece the inner and machine tool chief axis simultaneously, tightening the second counterpart makes bulge at the top of conical surface axle pressure even inflation, holds out against the coaxiality error that roll workpiece ensures workpiece axial line and machine tool chief axis;
4., the outer face of processing roll workpiece and outer circumference surface;
5., by roll workpiece take off, repeat the other end of 1. extremely 3. step processing roll workpiece;
6., take off roll workpiece, machine.
Described on base, described first counterpart and described second counterpart are made through over carburizing modulation treatment by 40Cr material.
First the coaxiality error of the first counterpart and machine tool chief axis and the error of perpendicularity of the first counterpart the inner and machine tool chief axis is ensured, then by the cooperation of conical hole, ensure the coaxiality error of the second counterpart and the first counterpart, namely ensure the outer face of the second counterpart and the coaxiality error of machine tool chief axis, then roll workpiece is loaded onto, expander is even inflation under the cooperation of conical surface axle and conical hole, hold out against the inner headed face of roll workpiece uniformly, to ensure the coaxiality error of roll workpiece and expander, namely ensure the coaxiality error of roll workpiece and machine tool chief axis, simultaneously, the inner face of roll workpiece and the end face of the shaft shoulder are fitted, the inner face of roll workpiece and the error of perpendicularity of machine tool chief axis can be ensured.
By above step, the coaxiality error of roll workpiece and machine tool chief axis is ensured, the error of perpendicularity of roll workpiece and machine tool chief axis is also ensured, when the precision of both direction is all ensured, workpiece is processed, the finished product that precision is higher can be obtained, in actual process, coaxiality error can ensure within 0.003mm, effectively ensure that and the stability that Bundy tube is produced improve the quality of Bundy tube, thus reduce production cost.
Adopt 40Cr materials processing, in process, carry out Carburization Treatment, reduce deflection, improve hardness, improve the machining accuracy of roll, by the Bundy tube roll of this processes, the processing to the Bundy tube of the materials such as SPCD, SPCE can be realized, and crudy and the precision of Bundy tube can be ensured.
