The rotary plate passes through the positioning mandrel hole and is installed on the transition connecting plate and is fixed by connecting bolts. The top of the positioning mandrel is installed and pressed through the open washer. The nut, the positioning block and the self-positioning block assembly are symmetrically installed on the rotary table, and the whole constitutes a device for processing hole systems on an ordinary lathe.

Wherein, a balance weight is installed on the transition connection plate.

The beneficial effects of the utility model are:

1. Use this device to complete the finishing machining of the flat hole system of similar small and medium-sized parts on the ordinary lathe, which can avoid the trouble of tool adjustment when the boring machine is boring.

2. In this device, the self-positioning structure of the positioning of the rough machining hole itself is used, so that the machining allowance of the hole is relatively uniform when machining on the lathe, and the machining defects of the rough machining hole can be well corrected during finishing machining. , reducing error remapping.

3. The use of this device expands the processing range of ordinary lathes, and has a reference effect in the processing of similar parts.
