Seven-axis five-linkage wood plug CNC machining center and method

Abstract

The invention discloses a seven-axis five-linkage wood plug CNC machining center and method. The machining center comprises a machine body assembly, a workbench assembly, a tool apron moving assembly,a tool apron assembly and a pneumatic chip removal assembly. The machine body assembly provides fixed supporting for all the other assemblies. Moreover, all components are compact in design and smallin size. Various lengths and shapes of wood workpieces can be clamped and a tool setting point can be positioned accurately through the workbench assembly. The tool apron moving assembly achieves twoplane mobile degrees of freedom and two rotary degrees of freedom of a tool apron. Through cooperation with three mobile degrees of freedom of the workbench assembly, seven-axis five-linkage in the machining process is achieved. The tool apron assembly can conduct positioning and clamping on cutting tools and provide cutting and rotating power. Alternate machining of the cutting tools is realizedthrough rotating of the tool apron. The machining center has the advantages that the machining center achieves one-time forming and is high in automation degree; the design of a novel planer tool isadopted, and the machining quality is improved; and the pneumatic chip removal assembly provides pneumatic power for a machine body and achieves the chip removal function.

Description

technical field [0001] The invention relates to a seven-axis five-link wooden tenon numerical control machining center and a method thereof, in particular for processing tenon and tenon grooves of various types of wood. Background technique [0002] With the rising of environmental protection and healthy consumption concepts and the continuous development of construction technology, wood with a long history has once again become a popular choice in the raw material market for furniture, houses and other products. As the most important wood tenon processing process in wood processing, most manufacturers At present, it is still at the production level of using old-fashioned woodworking planers and using the experience of master workers to process various types of wooden tenons. The labor intensity of workers is high and the production efficiency is low, so the quality of tenon processing cannot be guaranteed. Simultaneously, there are generally some problems in some wooden ten...

[0002] With the rising of environmental protection and healthy consumption concepts and the continuous development of construction technology, wood with a long history has once again become a popular choice in the raw material market for furniture, houses and other products. As the most important wood tenon processing process in wood processing, most manufacturers At present, it is still at the production level of using old-fashioned woodworking planers and using the experience of the master workers to process various types of wooden tenons. The labor intensity of workers is high, and the production efficiency is low, so the quality of tenon processing cannot be guaranteed.

Simultaneously, there are generally some problems in some wooden tenon processing numerical control machine tools that appear on the market at present, as a kind of numerical control wooden house tenon machine disclosed in the patent application publication number CN10191220A, it has adopted the structure of gantry type, and volume is bulky, occupies an area The area is large, the cost is high, and only a single drilling and milling function can be realized, and the versatility is poor. Another example is a CNC five-axis tenon processing machine tool disclosed in the patent application publication number CN103802180A. Although the automation level is relatively high and the processing range is wide, Small size, but due to the limitation of a single workbench, it cannot process long wood, and cannot realize high-efficiency operation of loading and processing at the same time
