Abstract

The invention provides a five-axis linked CNC (Computer Numerical Control) double-faced mill for processing an S-shaped curve surface of solid wood furniture. The five-axis linked CNC double-faced mill adopts a computer technology, a CAD (Computer-Aided Design) technology and a control technology to improve traditional solid wood processing equipment. The five-axis linked CNC double-faced mill utilizes the computer technology and the CAD technology to convert a user workpiece drawing into a track code capable of being identified by a five-axis control system; and the control system controls five straight-line axes to process the S-shaped curve surfaces at the two sides of a workpiece according to the track code. Procedures of milling, sanding, beveling, end processing and the like of a woodworking workpiece can be finished for one time. Four cutters process at the same time so that the processing speed is greatly higher than that of traditional equipment and the high precision is guaranteed; and the operation is simple, convenient and flexile and a template does not need to be manufactured.

Description

Five-axle linkage CNC Double Milling

Technical field

Five-axle linkage CNC Double Milling is applied to carpenter's furniture industry, belongs to carpenter's automation equipment.Can make things convenient for by this equipment, flexibly, efficiently processing has the solid wood furniture workpiece of various S type curvilinear planes, will mill, and bevelling, sanding, the operations such as end machining are disposable to be machined.Various desks for example, chair, the legs and feet of sofa and handrail etc.

Background technology

Along with the development of society, the improving constantly of domestic cost of labor, existing process equipment inefficiency, the profit margin of carpenter manufacturer is constantly compressed.Under such background, each carpenter manufacturer reduces cost in the urgent need to high efficiency automated production equipment.

Be to use the profile tracer machine now basically in the carpenter Furniture Factory, column mills, machining center.Wherein the profile tracer machine is to adopt oil pressure or pneumatic the driving, is subjected to the impact of oil pressure/air pressure and template factors, and the product of processing is unstable, and error ratio is larger, inefficiency, and need to make the pattern template.It is by manually processing that column mills, and efficient is low and cause easily industrial accident; Although and machining center can processed complex curved surface, equipment manufacturing cost is high, and working (machining) efficiency is low.

Summary of the invention

In order to raise the efficiency, reduce cost, according to the characteristics of carpenter's furniture, we propose a kind of 4 five-axle linkage CNC Double Millings that cutter is processed simultaneously that adopt that computer is combined with control technology that cad technique researches and develops.It also has the function of automatic loading/unloading, need not make template, can process efficiently the solid wood furniture workpiece with various S type curvilinear planes, to mill, bevelling, sanding, the operations such as end machining are disposable to be machined, flexible and changeable, simple to operation, not only reduce cost, and improved efficient, avoid the generation of security incident, also greatly improved machining accuracy.Be applicable to realize the batch production of solid wood furniture.

The specific embodiment

1, Machine Tool design becomes the form of 4 cuttves, and 4 cutter shafts are moved by servo motor driven; Two cuttves are on the left side of workbench, and 2 cutter the right at workbench in addition, the 160mm that mutually staggers between 4 cutter shafts, and the motion that is parallel to each other in the horizontal direction, workbench is done the horizontal movement perpendicular to 4 cutter shafts.

2, adopt ball screw as the transmission mechanism of 5 axles, guaranteed the precision of transmission.Wherein workbench adopts line slideway as guiding, 4 the feed shaft of cutter employing Du Chrome optical track as guiding.

3, workpiece is pressed on the workbench from top to bottom by cylinder clamp.

4, utilize our company to read user's workpiece drawing based on the software of VC++ exploitation, and convert the track code that five-axle numerical control system can be identified to, and have the function that mini line segment is optimized.

5, the control system that has five axle Continuous interpolation program functions realizes the processing to workpiece both sides S type curvilinear plane according to track code 5 linear axis of control (4 cutter shafts and workbench) interlock.

Claims

1. one kind based on computer technology, the five-axle linkage CNC Double Milling that cad technique combines with automated control technology, it is characterized in that: the track code that becomes 5 axle control systems to identify user's workpiece conversion of drawings, control system is according to speed and the position of 5 linear axis of track code control, thereby reach cutter shaft and workbench jointly controlled to realize processing to workpiece both sides S type curvilinear plane.

2. according to the CNC Double Milling that links according to claims 1 described 5 axles, user's conversion of drawings is become the track code of 5 axle control systems identification, it is characterized in that: based on VC++ the software of AutoCAD secondary development is translated into the code that control system can be identified with user's drawing (perhaps user dwg file), and the simulation machining locus.

3. according to 5 linear axis of right 1 described 5 axles interlock CNC Double Milling, it is characterized in that: adopt servomotor as power, carry out closed-loop control, ball screw is as transmission mechanism, thereby realization is to the high-precision positioning control of 5 linear axis.

4. according to the described 5 axles interlock of claims 1 CNC Double Milling, realize the processing to workpiece both sides S type curvilinear plane, it is characterized in that: 4 can realize that 4 different tracks process to cutter, will mill, and sanding, bevelling, the end machining operation is disposable to be machined.
