Fig. 7 is the Reconfigurable Machine Tools basic configuration figure provided in an embodiment of the present invention based on reconfigurability, including 6 kinds of structures
Type：Configuration (a) can process the end face of rotary work piece, structure with two sides and a upper surface, configuration (b) of workpieces processing
Type (c) can process two different workpiece simultaneously, and structure (d), (e) can process the surfaces of revolution of rotary work piece with (f).
To provided in an embodiment of the present invention, the Reconfigurable Machine Tools RMT based on reconfigurability carries out reconstrusctability analysis below,
It is analyzed including RMT production capacities retractility, convertibility and reconstitution time.
Wherein RMT production capacities retractility is analyzed as follows：
About the definition of retractility can be quickly and economically adjusted by increasing or decreasing manufacturing recourses in RMS
The production capacity of RMS is come the variation that meets the market requirement.RMT is expanded to, the scalability of RMT is then by add or delete mould
Block/component realizes the increase and decrease of lathe production capacity.Fig. 8 illustrates the production capacity telescopic process of RMT prototypes proposed by the present invention,
Middle ordinate indicates that the production capacity of RMT, abscissa indicate the function of RMT.It can be seen from the figure that the production with different function RMT
It can be by function arm-workbench of increase/deletion identical function to scaling.Module is also achieved during this
It reuses.
The scalability for the RMS being made of numerically-controlled machine tool can be defined as：
Scalability=100 × (1- minimums increase (subtracting) and measure capacity/existing capacity) %
Wherein, minimum (subtracting) amount that increases is a lathe.If minimum (subtracting) amount that increases with very little can meet new demand,
So rmc system is just provided with telescopic in height.But this process needs to reserve certain space increase for newly-increased lathe
Original capital input.If using RMT prototype buildings RMS proposed by the present invention, the flexible minimum production capacity of system increases (subtracting)
Amount realization method becomes one group of function arm-workbench pair from from a machine tool.This method not only can be to avoid rmc system layer
The significantly adjustment in face, and original retractility reserved space initial outlay can have been saved.Based on numerically-controlled machine tool and RMT
The different scalabilities of RMS are as shown in Figure 9.Obviously, the RMT proposed enhances the retractility of RMS.
RMT power and energies are analyzed as follows：
Convertibility refers to quickly adjusting the function of RMT with minimum input to respond the ability of new demand, convertibility
It is concerned with the conversion of lathe function, as shown in Figure 10.It, can be real in several ways based on the RMT prototypes of the present invention
The conversion of existing RMT functions：1) replace existing module with different function modules (configuration a1 is transformed into configuration b1)；2) in difference
Position install identical/different module (when being transformed into configuration b2 from configuration b1, identical function module be mounted on different positions
It sets；When being transformed into configuration b4 from configuration b3, different function modules is mounted on different positions, and the result of both conversions is all
Produce the new RMT configurations with different function；3) as long as the installation direction for changing existing capability module (is converted when from configuration a1
When to configuration a3, it is only necessary to which new lathe function can be realized in the installation direction for changing workbench).It reuses in this process
Primary module increases the reuse rate of primary module.In addition, the replacement of component can also obtain new function, but component is nonstandard
Quasi- structure, unit replacement can be potentially encountered unpredictable situation, therefore the present invention has abandoned this mode.
RMT reconstitution times are analyzed as follows：
In traditional RMT restructuring procedures, preparation stage selection meets module needed for new demand, and reconstruction stage into
Row installation, and new function RMT is tested.In the RMT restructuring procedures of the present invention, preparation stage selection meets new demand institute
The component that needs simultaneously attaches it on primary module, and carrying out test for the first time can normal work with the component for ensuring to be installed to primary module
Make.If necessary to prepare multiple primary modules, then it can be carried out at the same time preparation, save time.It is being mounted with New Parent
Primary module it is ready after, attach it on RMT, and carry out second and test.It is of the invention compared with traditional RMT
RMT has done more work in the preparation stage, to save the time of subsequent reconstruction stage, as shown in figure 11, t11<
T21, t12<T22, so t11+t12<t21+t22.In fact, the efficient reconstruction of the present invention benefits from " plug and play " theory.
The work of preparation stage and 3- main mould block structures with standard interface are that " plug and play " has carried out sufficient preparation.This is one
The new reconfiguration mode of kind.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's
Within protection domain.
