Description

Technical Field

[0001] The utility model relates to the technical field of connecting plates for milling machines, in particular to a connecting plate for milling machines. Background Art

[0002] A milling machine is a machine tool with a wide range of uses. It can process planes, grooves, toothed parts, spiral surfaces and various curved surfaces. In addition, it can also be used for processing the surface of a rotating body, inner holes and cutting. When the milling machine is working, the workpiece is mounted on a workbench or an accessory such as a dividing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the workbench or the milling head. The workpiece can obtain the required processing surface. Due to multi-blade intermittent cutting, the productivity of the milling machine is relatively high. A milling machine is a machine tool that uses a milling cutter to mill workpieces. In addition to milling planes, grooves, gear teeth, threads and spline shafts, the milling machine can also process more complex surfaces. It is more efficient than a planer and is widely used in mechanical manufacturing and repair departments. When installing the milling cutter, a connecting disc needs to be installed on the end face of the spindle before the milling cutter can be installed.

[0003] During the operation of the milling machine, the milling cutter needs to withstand large cutting forces and vibrations, which can easily cause damage. In addition, because different products need to be processed, milling cutters of different specifications are often replaced. The milling cutter is directly installed on the spindle of the milling machine, which makes the installation and disassembly of the milling cutter more cumbersome and affects work efficiency.
