Device used for driving shaft key seat machining

Abstract

The invention relates to the field of driving shaft machining, in particular to a device for driving shaft key seat machining. A positioning sleeve of the device comprises an inner hole and four machining holes. The inner hole is formed in the dead center position of the positioning sleeve, the distance between each machining hole and the inner hole is the same, and the distance between every twoadjacent machining holes is also the same. A positioning plate comprises a face plate, a pin hole, a bottom plate and a fixing clamping groove, the pin hole is formed in the face plate, and fixing clamping grooves are formed in the two sides of the bottom plate. The device is adopted for machining the key seat of a driving shaft and has the beneficial effects that the machining precision is high,and the machining process is simple.

Description

technical field [0001] The invention relates to the field of mechanical processing of drive shafts, in particular to a device for milling key grooves of drive shafts. Background technique [0002] like figure 1 , figure 2 As shown in the figure, four evenly distributed milling key slots need to be milled on one end of the drive shaft for mounting the sprocket. [0003] There are technical obstacles in milling 4 milling keyways with the existing technology. The first is that the precision of the uniform distribution of the four milling keyways must be very high. It is difficult to achieve the machining accuracy by conventional processing methods, resulting in low processing yield; The drive shaft is long, huge, and heavy, and it is impossible to use conventional dividing heads to achieve accurate division of angles. The existing method relies on experienced workers for processing, which is difficult to process and is prone to substandard products, which will cause the dri...

[0003] There are technical obstacles in milling four milling keyways with the existing technology. The first is that the precision of the uniform distribution of the four milling keyways must be very high. It is difficult to achieve the machining accuracy by conventional processing methods, resulting in low processing yield; the second is The drive shaft is long, huge, and heavy, and it cannot use conventional dividing heads to achieve precise division of angles

The existing ones rely on experienced workers for processing, which is difficult to process and prone to substandard products, which will cause the drive shaft to be scrapped and waste production resources.
