Full-automatic numerical control double-head milling machine

Abstract

The invention belongs to the technical field of machining, and particularly discloses a full-automatic numerical control double-head milling machine. The full-automatic numerical control double-head milling machine comprises a fixed base, a sliding base, a rotary working table, a material pressing mechanism, a first station, a second station, an automatic positioning device and a numerical controlsystem; a workpiece is placed on the rotary working table and is firstly compressed through the material pressing mechanism, a reference surface or a first machining face of the workpiece is determined through the automatic positioning device, then a second machining face is determined through the numerical control system, a first milling head and / or a second milling head are / is driven to the corresponding positions / position according to the automatic positioning device and / or the actual size of the workpiece, and a sliding base finally drives the workpiece on the rotary working table to passthrough the first station and / or the second station to complete milling of the workpiece. By means of the full-automatic numerical control double-head milling machine, the milling technology is simplified, the machining accuracy is improved, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of machining, and specifically discloses a fully automatic numerically controlled double-head milling machine and a milling process using the fully automatic numerically controlled double-head milling machine. Background technique [0002] A milling machine refers to a machine tool that uses a milling cutter to mill a workpiece. Because of its remarkable advantages such as high efficiency and good applicability, it has been widely used in modern machinery manufacturing and machinery repair departments. [0003] The existing milling machines have the following shortcomings: 1. Manual participation in the fixing of the workpiece and the measurement and positioning of the reference plane and the processing surface is required. The degree of automation of the equipment is not high, and random errors are prone to occur during the fixing, measurement and positioning of the workpiece, which in turn affects the The ...

Problems solved by technology

[0003] The existing milling machines have the following shortcomings: 1. Manual participation in the fixing of the workpiece and the measurement and positioning of the reference plane and the processing surface is required. The degree of automation of the equipment is not high, and random errors are prone to occur during the fixing, measurement and positioning of the workpiece, which in turn affects the Processing accuracy, resulting in increased defective rate

2. The existing milling machines do not have the chamfering function or the chamfering function is not perfect. In practice, when chamfering the milled workpiece, it is often necessary to replace the machine or manually reposition the workpiece. The process is discontinuous and the efficiency is low. It is easy to affect the machining accuracy due to the appearance of accidental factors

3. The conventional milling machine has only one milling head, and can only process a certain milling surface at a time. When there are multiple milling surfaces on the workpiece to be processed, it needs to be completed in sequence and step by step. The processing efficiency is low, and it is necessary to replace the milling surface. The workpiece is repeatedly positioned, and the processing efficiency needs to be improved urgently
