A hexagonal tool post for a CNC five-axis tenon processing machine tool

Abstract

The invention discloses a hexagonal cutter rest for a numerical control five-axis tenon machining machine tool. Spindle components are connected to a cutter rest body and internally provided with electric spindles, and the electric spindles are provided with cutters in a clamping manner. The spindle components are arranged on the edges of the cutter rest body in the axial direction and the radial direction. The cutter rest body is connected with the machine tool through a roller component. Rotation of a roller drives the hexagonal cutter rest to do indexing rotation around the center axis of the cutter rest body by 0 degree to 360 degrees in the plane of the Y axis and the Z axis, cutter replacing relative to a workpiece is finished, and more time is saved. The numerical control five-axis tenon machining machine tool applying the hexagonal cutter rest comprises a lathe body, a stand column, a workbench, a cutter replacing device and a numerical control unit used for controlling the machine tool, the roller component is used for connecting the hexagonal cutter rest with the numerical control five-axis tenon machining machine tool. The workbench is arranged on the #-shaped plane of an X-axis guide rail and a Y-axis guide rail and can move back and forth in the X-axis direction and the Y-axis direction. A sliding rail, the roller component and the hexagonal cutter rest can move back and forth in the Z-axis direction. The machine tool can machine complex tenons.

Description

technical field [0001] The patent of the invention relates to the field of machine tool processing, in particular to a hexagonal tool post used in a CNC five-axis tenon processing machine tool. Background technique [0002] The existing CNC woodworking machine tools have a single structure and function and are difficult to adjust; basically, the material is manually fed, and then a simple tenon of a certain size is processed by the cutter head; whether it is a traditional tenoning machine or an existing CNC tenoning machine None of these machines can achieve automatic intelligent control in the full sense. They are inefficient, time-consuming and labor-intensive, and it is difficult to process complex mortise and tenon structures at one time; The machine tool can perform end milling and horizontal milling on the workpiece by changing the cutter head on the electric spindle many times and turning the electric spindle to make it 0 degrees and 90 degrees, but it takes a long ti...

Problems solved by technology

[0003] The purpose of the present invention is to design a hexagonal tool holder for CNC five-axis tenon processing machine tools in view of the deficiencies in the prior art. Due to the use of the hexagonal tool holder, the time for tool replacement by loading and unloading the cutter head is greatly reduced. , only need to rotate the tool holder to realize the tool change relative to the workpiece. At the same time, since there are six sets of electric spindles on the hexagonal tool holder, and they are arranged in an axial and radial staggered manner relative to the tool holder body, the end milling and The conversion of horizontal milling is more convenient. It only needs to rotate the cutter head of the corresponding electric spindle on the tool holder to the workpiece processing position. This solves the problem that the shape of the mortise processed without loading and unloading the cutter head is single, and in a short unit Complicated tenon processing cannot be completed within a short period of time, and it cannot meet the needs of mass production and the production efficiency is low; the CNC five-axis tenon processing machine tool using this hexagonal tool holder is especially suitable for processing complex tenon and tenon structures.
