Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a vertical processing device for a reduction housing. Background Art

[0002] like Figure 1-2 The reduction housing 100 shown not only needs to be processed on its upper end face and circumferential surface, but also needs to be drilled with a circle of multiple inner holes 101 and a circle of multiple outer holes 102 on its upper end face; however, since there is a thinner convex edge 103 on its upper end face and a thinner retaining ring 104 in the center hole cavity, the retaining ring 102 and the convex edge 101 are easily crushed, so the end face pressure plate and the center hole pin are not desirable. If the edge of the upper end face is pressed by a pressure plate, it is easy to interfere with the tool; if it is fixed on the cylinder under the upper end face by a three-jaw fixture, it is not convenient for circular surface processing, so a vertical processing device with a small contact area, reliable clamping, high efficiency, and suitable for mass production is urgently needed.
