Borehole and counterbore machine for annular mold

Abstract

The invention discloses a borehole and counterbore machine for an annular mold in the field of bore machining tools, which comprises a main spindle box body. At least one side of the main spindle box body is provided with a supporting beam, a horizontal guide rail is arranged on the supporting beam, and a horizontal slide block is arranged on the horizontal guide rail in a matching mode. The horizontal slide block and the horizontal guide rail are in transmission connection through a lead screw nut pair. A vertical guide rail is fixedly arranged on the horizontal slide block, and a vertical slide block is arranged on the vertical guide rail in a matching mode. The vertical slide block and the vertical guide rail are in transmission connection through another lead screw nut pair. A bit component is fixed on the vertical slide block, and a speed-reducing mechanism is fixed in the main spindle box body. An input shaft of the speed-reducing mechanism is connected with an end of an output shaft of a servo motor. An output shaft of the speed-reducing mechanism extends upwards, an upper end of which is connected with a rotating table. A plurality of rotating steps in step-shaped distribution are arranged on the rotating table, wherein the rotating steps and the rotating table are arranged coaxially. The borehole and counterbore machine for the annular mold has the advantages of accurate positioning of a workpiece and convenient processing, and can be applied to machining the annular mold or radial multi-hole parts.

Description

technical field [0001] The invention relates to a hole processing machine tool, in particular to a machine tool for processing radial holes of a ring die of a ring die granulator. Background technique [0002] In the processing technology of feed and grain, there is a ring die granulator for granulation. The ring die is one of its key components. The ring die itself is a hollow cylinder with a certain wall thickness. There are several radial through-holes on the outer periphery of the die. The through-holes are die holes. The number of die holes is usually thousands to tens of thousands. When working, the material is squeezed from the die holes by the pressure roller in the inner cavity of the ring die. out, and then cut into pellets by the cutting device; in order to adapt to the extrusion of materials and avoid too much friction, the diameters of the inside and outside of the die hole are not exactly the same, often the outer diameter is large and the inner diameter is sma...
