Method of assembly and precision calibration of numerical control four-axis ring die deep hole drill machine tool

Abstract

The invention discloses a method of assembly and precision calibration of a numerical control four-axis circular ring die deep hole drill machine tool. The machine tool is used for machining a stainless steel ring die in a feeding stuff granulator, a vertical type rotary working platform is adopted in the middle of the machine tool, and four-axis double-station deep hole main shafts are adopted on two sides of the machine tool. When the machine tool machines, a workpiece is installed on a numerical control index table, a four-claw chuck is used for clamping a ring die of the workpiece, and the situation that the outer circle of the ring die beats and the end face of the ring die beats is guaranteed. Numerical control sliding tables are symmetrically arranged at the left and the right, and ball screws and ball guide rails are installed on the sliding tables. The machine tool is controlled by a servo motor to move front and back so as to enable a main shaft guide sleeve box to move, when the machine tool works, guide holes are tightly attached to the surface of the workpiece, and when moving cuttings are carried out, the machine tool moves on the ball guide rails to achieve the machining of holes in the outer circle of the ring die.

Description

technical field [0001] The invention mainly relates to the fields of feed industry and papermaking industry, in particular to an assembly method of a deep hole drilling machine. Background technique [0002] As we all know, because the ring die is one of the key parts of the pellet feed press machine, it is also a vulnerable part, and the price is expensive; whether its quality is good and stable, directly affects the service life of the ring die and the output of the pellet feed press machine. , Feed quality, thus affecting the production cost of feed processing. The surface finish of the ring die hole directly affects the key to whether the ring die can discharge smoothly when producing feed; the uniform distribution of the ring die hole on the circumferential surface is whether the inner cavity is evenly stressed during the extrusion process. The main form of ring die failure is that the die hole and the inner ring surface of the ring die are worn out and scrapped, and t...
