Problems solved by technology
In order to ensure the rigidity of the machine tool structure, the inertia moment of the cross-section of the beam part in the C-shaped structure is usually designed relatively large, so that the deformation is as small as possible, which is contrary to the original intention of the machine tool structure miniaturization
For the ∏-type gantry structure, the main shaft is located in the center of the beam fixed on the upper end of the gantry, the deformation can be completely suppressed, and the structural rigidity is very good, but this structure will greatly affect the convenience of operation which is very important to the machine tool

Embodiment Construction
[0016] The present invention-micro-electrolytic machining machine tool mechanism, as shown in FIG. The present invention also includes double columns 5 and 5 1 And a pair of parallel ball guide rails installed on it are perpendicular to the workbench. The workpiece is placed in the work box fixed on the workbench.
[0017] As shown in Figure 2, the combined bearing seat of the present invention includes an upper bearing seat 10, a lower bearing seat 9, a side plate 30 and a side plate 30 1 , together constitute a combined integral bearing seat similar to a rectangular frame, and this integral combined bearing seat is connected with the carriage 7 by screws. During the machining process, the tool electrode mounted on the spindle head is subjected to an external force in the vertical direction (Z direction), and this force is transmitted to the shaft and causes the shaft to produce a certain Z direction displacement, compared with the traditional upper and lower separation bea...

A fine electrolytic machine tool with a combined gantry structure including two vertical columns and combined bearing seat is composed of base, bench, operating box, and mainshaft installed on said combined bearing seat. Said two vertical columns have a pair of parallel guide tracks with slide blocks. Said combined bearing seat is connected to said slide blocks via a carriage. Said mainshaft has two drivers for vertical moving and rotation.
Description
technical field [0001] The invention belongs to the field of electrolytic machining machine tools, in particular to a structural design of a micro electrolytic machining machine tool. Background technique [0002] More and more microstructures appear in the manufacturing fields of aerospace, instrumentation, and precision molds. As a special processing technology, electrolytic machining technology has also been studied and applied to microfabrication and micromanufacturing. [0003] At present, micro electrolytic machining machine tools usually adopt a vertical C-shaped structure or a ∏-shaped gantry structure. For the micro electrolytic machining machine tool with vertical C-type structure, the spindle head part can be simplified as the cantilever end of the cantilever beam structure. If it is subjected to a large electrolyte pressure during processing, it will produce certain deformation. In order to ensure the rigidity of the machine tool structure, the moment of inertia...
