Description

An automatic conveying device for a circular workpiece milling machine

technical field

The invention relates to the related technical field of milling machine workpiece conveying, in particular to an automatic conveying device for a circular workpiece milling machine.

Background technique

A milling machine is a machine tool that uses a milling cutter to mill a workpiece. It mainly refers to a machine tool that uses a milling cutter to process various surfaces on a workpiece. Usually, the rotation of the milling cutter is the main movement, and the movement of the workpiece and the milling cutter is the feed movement. It can process planes and grooves, and can also process various curved surfaces, gears, etc. It can be said that milling machine is a machine tool with a wide range of uses. The milling machine can process planes, grooves, toothed parts, spiral surfaces and various curved surfaces. In addition, it can also be used to process and cut off the surface and inner holes of the rotating body. When the milling machine is working, the workpiece is installed on the workbench or the accessories such as the indexing head. The milling cutter rotates as the main movement, supplemented by the feed movement of the worktable or the milling head, and the workpiece can obtain the required processing surface. The blade is cut intermittently, so the productivity of the milling machine is high. In the production of workpieces on the actual milling machine, a kind of equipment widely used in the process of surface flatness cutting treatment is the double-sided milling machine cutting machine. At present, the double-sided milling machine cutting The conveying device of the machine generally adopts the structural form of double-sided parallel nip roller conveying, but this structural defect is obvious, and the following problems generally exist:

First, the pressure feeding thickness of the two parallel nip rollers is relatively limited, and the intelligently processed rough workpieces have relatively consistent dimensions, but the size of the rough workpiece often leads to transportation difficulties and equipment damage, which directly affects the processing efficiency and the service life of the equipment;

Second, the pinch roller transport can only send the blank workpiece to the position of the milling cutter, and cannot complete all the operations when the machine is shut down, but must leave a small amount of blank workpieces that cannot meet the needs of subsequent production in the milling machine, resulting in a low product yield;

Third, when the workpiece is clamped and fixed on the milling machine, the blanks are often fixed one by one manually, which not only wastes manpower, material resources and working time to a certain extent, but also cannot be automatically dropped after the workpiece is processed. fall, higher limitations;

For this reason we propose a kind of automatic conveying device of circular workpiece milling machine.
