Abstract
The utility model discloses a machine tool with a main shaft balancing device. The machine tool with the main shaft balancing device comprises a stand column, a main shaft box body and a saddle, wherein the saddle moves vertically on the stand column through a vertical guide rail, and the main shaft box body horizontally moves on the saddle through a horizontal guide rail. The machine tool is provided with the main shaft balancing device. The main shaft balancing device comprises a pressure accumulator, a horizontal oil hydraulic cylinder and a balancing oil hydraulic cylinder. The pressure accumulator, the horizontal oil hydraulic cylinder and the balancing oil hydraulic cylinder are connected through an oil hydraulic circuit. The machine tool with the main shaft balancing device is capable of improving processing quality, reducing fault rates and prolonging service life.
Description
Technical field
The utility model relates to a kind of toolroom machine with main shaft balance device.
Background technology
Existing toolroom machine mainly comprises lathe, saddle and a main spindle box body with column, and does not have the principal axis balance main shaft, during the processing operation, causes easily the imbalance state of main shaft, thereby affects machining accuracy and working (machining) efficiency.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, and a kind of toolroom machine with main shaft balance device is provided, and it can improve crudy, reduces spoilage, increase service life.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of toolroom machine with main shaft balance device, comprise column, main spindle box body and saddle, saddle is vertically mobile on column by vertical guide rail, main spindle box body moves horizontally at saddle by horizontal guide rail, described toolroom machine is provided with a main shaft balance device, and described main shaft balance device comprises an accumulator, a horizontal oil hydraulic cylinder and an equilibrium oil cylinder pressure, and described accumulator, horizontal oil hydraulic cylinder and balance oil hydraulic cylinder connect by oil hydraulic circuit.
Accumulator inside is provided with a confining gas device, horizontal oil hydraulic cylinder is arranged between saddle and the main spindle box body, when main spindle box body outwards moves, hydraulic oil in the horizontal oil hydraulic cylinder is extrapolated, via oil hydraulic circuit part hydraulic oil is directed into accumulator, the accumulator internal pressure is improved, and the volume of confining gas device is reduced, produce a back pressure hydraulic oil is outwards derived; The equilibrium oil cylinder pressure is arranged on the main spindle box body, makes the equilibrant force that produces vertical direction act on main spindle box body, the moment of torsion that produces because of gravity when namely suitably the balancing main shaft casing stretches out in order to the back pressure of accepting accumulator and providing.
By main shaft balance device is set, makes the utility model toolroom machine can improve crudy, reduce spoilage and increase service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model main shaft balance device structural representation.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model provides a kind of toolroom machine with main shaft balance device, comprise column 1, main spindle box body 2 and saddle 3, saddle is vertically mobile on column by vertical guide rail 4, main spindle box body moves horizontally at saddle by horizontal guide rail, described toolroom machine is provided with a main shaft balance device, described main shaft balance device comprises an accumulator 5, a horizontal oil hydraulic cylinder 6 and an equilibrium oil cylinder pressure 7, and described accumulator, horizontal oil hydraulic cylinder and balance oil hydraulic cylinder connect by oil hydraulic circuit 8.
Accumulator inside is provided with a confining gas device 9, horizontal oil hydraulic cylinder is arranged between saddle and the main spindle box body, when main spindle box body outwards moves, hydraulic oil in the horizontal oil hydraulic cylinder is extrapolated, via oil hydraulic circuit part hydraulic oil is directed into accumulator, the accumulator internal pressure is improved, and the volume of confining gas device is reduced, produce a back pressure hydraulic oil is outwards derived; The equilibrium oil cylinder pressure is arranged on the main spindle box body, makes the equilibrant force that produces vertical direction act on main spindle box body, the moment of torsion that produces because of gravity when namely suitably the balancing main shaft casing stretches out in order to the back pressure of accepting accumulator and providing.
By main shaft balance device is set, makes the utility model toolroom machine can improve crudy, reduce spoilage and increase service life.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
