Problems solved by technology

In the prior art, the shape of the shaft coupling is relatively complicated. For most of the shaft couplings with complex shapes, most of them are casted, and the strength required by the shaft coupling is high, and the strength of the cast metal parts is very low, while Machining of steel parts is difficult, therefore, there is room for improvement

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] Such as figure 1 and figure 2 Shown: the present invention comprises the following steps:

[0022] (1) Clamp the steel parts of sufficient size on the workpiece table of the CNC milling machine with a vise;

[0023] (2) Use a corrugated wool milling cutter with a larger diameter to mill out the general shape of the coupling from the part below the connecting shaft and leave a margin of 2mm, and reserve the connecting shaft 7 and the small connecting shaft 8 to form a rectangular reserved matrix 9. Mill the excess material above the flat part 1, the first boss 2 and the second boss 3, and leave a margin of 2 mm;

[0024] (3) Use a fine milling cutter with a size smaller than half the diameter of the through hole 4 to mill the through hole in a spiral descending way, and then finish machining along the cutting path of the corrugated milling cutter in step (2), with...

Abstract

The invention discloses a mechanical coupling processing method. Compared with the prior art, by means of the method, a steel piece can be cut, processed and shaped, processing and quick shaping are achieved, and tedious processes are reduced. Besides, the strength of a coupling obtained through cutting shaping is much higher than that of a coupling obtained through casting shaping, the processingmethod is reasonable, the strength of the coupling is ensured, and the mechanical coupling processing method has application and popularization values.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a machining method for a mechanical coupling. Background technique [0002] Couplings are also called couplings. A mechanical component used to firmly couple the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes it is also used to connect shafts and other parts (such as gears, pulleys, etc.). It is often composed of two halves, respectively connected by keys or tight fits, fastened at the ends of the two shafts, and then connected by some means. The coupling can also compensate for the offset between the two shafts due to inaccurate manufacturing and installation, deformation or thermal expansion during work (including axial offset, radial offset, angular offset or comprehensive offset) ; And ease the impact, absorb vibration. In the prior art, the shape of the shaft coupling is relatively complicated. Fo...
