Background technology
Make the field at Digit Control Machine Tool, the frame for movement of traditional Digit Control Machine Tool adopts in-line connected mode mostly, makes lathe be easy to generate the accumulation of error, and integral rigidity is not high, and machining accuracy is lower.The nineties in last century, the birth of parallel machine allows people see the hope of Digit Control Machine Tool.That parallel machine has is simple in structure, rigidity is high, error free accumulation, heavy moving parts are little, be easy to realize advantages such as high-speed motion, has remedied the deficiency of traditional Digit Control Machine Tool to a certain extent.Yet parallel machine also has its born defective, 6DOF parallel machine especially, and shortcomings such as the motion coupling is strong, working space is little, numerical control programming complexity make applying of parallel machine be subjected to restriction largely.In recent years, the lower-mobility parallel machine more and more is subjected to researcher's attention and favor, and some lower-mobility parallel machines have obtained successful Application.
In order to satisfy the complicated day by day and special processing request to part to be processed, the processing characteristics of Digit Control Machine Tool also needs to improve day by day.Series-parallel machine tool combines the advantage of traditional machine tool and parallel machine preferably, and this series products has more application prospects in the manufacturing field.
Summary of the invention
The object of the present invention is to provide a kind of multi-shaft linkage series-parallel machine tool, that this lathe has is simple in structure, rationally distributed, processing flexibly, be easy to control, working space is big, machining accuracy is high and can realizes advantage such as horizontal-vertical double-purpose, combine the advantage of tandem and parallel lathe, can satisfy multi-axis linkage numerical control processing request complex-curved class part.
A kind of multi-shaft linkage series-parallel machine tool that the present invention proposes, comprise lathe bed, install main shaft moving platform, install and be cut the workbench of workpiece and be arranged on three root posts on the lathe bed, this three root post is triangularly arranged, all dispose the saddle of moving linearly on each column guide rail, these three saddles are by the motor-driven that is installed in each column, and the moving platform of this installation main shaft is connected to form space closed chain mechanism in parallel by three side chains with three saddles.Described space closed chain mechanism in parallel is used to realize two-dimentional one-movement-freedom-degree and one dimension rotational freedom, the workbench that described installation is cut workpiece is used to realize one dimension one-movement-freedom-degree and one dimension rotational freedom, and this workbench closed chain mechanism in parallel with the space is carried out nearly five interlock control.
Characteristics of the present invention and technique effect
The space of series-parallel machine tool of the present invention closed chain mechanism in parallel is used to realize two-dimentional one-movement-freedom-degree and one dimension rotational freedom, workbench is used to realize one dimension one-movement-freedom-degree and one dimension rotational freedom, and this workbench closed chain mechanism in parallel with the space is carried out nearly five interlock control.
This lathe has the following advantages: (1) is simple in structure; (2) rigidity height; (3) numerical control programming is easy; (4) have bigger working space and lathe volume ratio; (5) parallel institution can provide main shaft bigger slewing area, can realize horizontal-vertical double-purpose.These advantages make this mechanism be easier to design and control, and its flexibility ratio is better, and machining accuracy is higher, can satisfy the multi-axis linkage numerical control processing request to complex-curved class part.
