Description

Carving mills combined numerically controlled machine

Technical field

The utility model relates to a kind of carving and mills combined numerically controlled machine, and it belongs to the Machining Technology field.

Background technology

The original number control milling machine is because base is " 1 " font structure, and it is less with the contact area on ground, makes the less stable that lathe is whole; When the big workpiece of processing; Owing to receiving force unbalance to cause the lathe inclination, thereby cause the processing work precision relatively poor, and increased machining period greatly.

The utility model content

The utility model is to the long defective of CNC milling machine base less stable, machining period in the prior art, and the utility model provides a kind of carving to mill combined numerically controlled machine.

The technical scheme that the utility model solves the problems of the technologies described above is following:

A kind of carving mills combined numerically controlled machine, comprises base, workbench and column, and said workbench is installed on the base through X axial filament bar, Y axial filament bar and saddle, and through pressing plate with stationary table on saddle, said column is fixed on base top; Through Z axial filament bar slide is installed on the said column, said column is provided with chain wheel support and guide post, through sprocket shaft sprocket wheel is installed on the said chain wheel support, and said sprocket wheel is provided with chain; One end of said chain is fixed with balance iron, and the other end is installed on the slide through chain joint; Said slide top is equipped with knife striking cylinder through support, through flange main motor is installed, and the below is provided with main shaft; Said base is " T " font structure, promptly is fixed with support bar in the front end both sides.

Further, the two ends of said X axial filament bar are provided with gland.

Further, the chain of said balance iron end is provided with fairlead, and said fairlead is fixed on the column.

Compared with prior art, the beneficial effect of the utility model is: the base designs of " T " font structure with receiving force direction by stressed the stressed of three directions that change into of traditional both direction, makes the stability of base improve, thereby has avoided the generation of inclination phenomenon; The stability-enhanced while makes the speed of mainshaft improve greatly, thereby can process big, the complicated workpiece of weight, has reduced machining period, has improved working (machining) efficiency and machining accuracy greatly.

The specific embodiment

Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.

A kind of carving mills combined numerically controlled machine; Comprise base 1, workbench 4 and column 6; Said workbench 4 is installed on the base 1 through X axial filament bar 22, Y axial filament bar 5 and saddle 2; And through pressing plate 3 workbench 4 is fixed on the saddle 2, the two ends of said X axial filament bar 22 are provided with gland 23, and said column 6 is fixed on base 1 top; 6 are equipped with slide 21 through Z axial filament bar 12 on the said column, and said column 6 is provided with chain wheel support 9 and guide post 11, through sprocket shaft 17 sprocket wheel 16 is installed on the said chain wheel support 9, and said sprocket wheel 16 is provided with chain 10; One end of said chain 10 is fixed with balance iron 14, and the other end is installed on the slide 21 through chain joint 18, and the chain 10 of said balance iron 14 ends is provided with fairlead 15, and said fairlead 15 is fixed on the column 6; Said slide 21 tops are equipped with knife striking cylinder 13 through support 8, through flange 20 main motor 19 are installed, and the below is provided with main shaft 7; Said base 1 is " T " font structure, promptly is fixed with support bar 23 in the front end both sides.

The utility model is when work, and base 1 design of " T " font structure makes the whole stability in the end improve; The stability-enhanced while; Make main shaft 7 rotating speeds improve greatly; The translational speed of X axial filament bar 22, Y axial filament bar 5 and Z axial filament bar 12 is increased to 50m/min by original 20m/min; Thereby can process big, the complicated workpiece of weight, reduce machining period, reach the purpose that has improved working (machining) efficiency and machining accuracy greatly.

The workbench 4 of traditional machine tool is when moving to saddle 2 other ends; Can be owing to the change of center of gravity produces the phenomenon of inclination; And saddle 2 centers of gravity of the utility model are on the center line of 10 on 1 liang of chain of base all the time, and when workbench 4 moved to saddle 2 other ends, workbench and saddle 2 common centers of gravity still were on base 1 one of them chain 10; Avoid the generation of inclination phenomenon, therefore can guarantee the machining accuracy of workpiece.

The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
