Description
Technical field
The utility model relates to vertical machining centre technical field, especially relates to the built-in nitrogen balance device of a kind of vertical machining centre.
Background technology
Along with constantly popularizing of machining center, extensive Precision Machining is achieved.Current vertical machining centre balance weight mechanism mainly still adopts balancing weight to solve the counterweigh problem of main shaft movement vertically, principle is: when spindle motor drive shaft moves up and down, balancing weight to be connected with main shaft by chain and to drive main shaft to move up and down, help the gravity effect overcoming main shaft, reduce the power needed for spindle motor lifting spindle, and reduce the quick downslide problem that may occur when moving down.Disclosed in Chinese patent ZL201020103046.3 " a kind of device that moves up and down for machining center balancing weight ", this device comprises column, the top of described column is provided with guide pillar support near left end place, the bottom of guide pillar support is provided with balancing weight guide pillar, the bottom of balancing weight guide pillar is connected with described column by guide pillar lower carriage, the right side of balancing weight guide pillar is provided with balancing weight, is connected between balancing weight with balancing weight guide pillar by linear bearing.Linear bearing is increased between balancing weight guide pillar and balancing weight, balancing weight high speed is moved up and down more stable, but still there is following defect in this mode: 1) balancing weight volume is large, mobile inertia is large, easily produce mechanical shock, vibration and noise time mobile, easily affect the machining accuracy of lathe; 2) there is weight difference and not easily regulate in Balance weight end and mobile terminal; 3) balancing weight easily produces double swerve, causes the instability of machining accuracy, not easily improves machining accuracy and the surface quality of product." a kind of counterweight balancing device of machining center " this device as disclosed in Chinese patent 201120154514.4 comprises nitrogen pot, tracheae and balance cylinder; Described tracheae is communicated with the gas outlet of nitrogen pot and the lower cylinders of balance cylinder; Described balance cylinder is vertically arranged, and piston rod stretches out lower cylinders and fixes with main shaft, and described nitrogen pot is fixed on the side of machining center column by nitrogen pot support; Described balance cylinder is fixed on the top of machining center column by air cylinder support.This device can ensure the spindle motor of machining center balancing the load when mobile, and main shaft is lower steadily mobile in vertical direction, and without impacting, power consumption is few, fast response time, thus saves the energy, improves machining accuracy, and is easy to control.But this device is appointed and so be there is following defect: nitrogen pot is fixed on the exterior lateral sides of column, and compensating cylinder is vertically fixed on main spindle box top, affects attractive in appearance, takes up space.
Utility model content
The technical problems to be solved in the utility model is: the exterior lateral sides being fixed on column in order to overcome nitrogen pot in prior art, affects attractive in appearance, and compensating cylinder is vertically fixed on main spindle box top, takes up space, and provides a kind of vertical machining centre built-in nitrogen balance device.
The utility model solves the technical scheme that its technical problem adopts: the built-in nitrogen balance device of a kind of vertical machining centre, comprise nitrogen pot, nitrogen balance support, oil pipe and nitrogen balance cylinder, described nitrogen pot is fixedly mounted in column, described nitrogen balance support is fixedly mounted on the top of column, described nitrogen balance cylinder is vertically arranged, described nitrogen balance cylinder lower cylinders is fixedly mounted in spindle box part, the piston rod of described nitrogen balance cylinder stretches out lower cylinders and is fixedly connected with nitrogen balance support, described oil pipe is communicated with the gas outlet of nitrogen pot and the top cylinder body of nitrogen balance cylinder.
Described nitrogen pot is fixedly mounted by nitrogen pot support.
The gas outlet of described nitrogen pot is provided with the controlling organization controlling opening and closing.
The beneficial effects of the utility model are, nitrogen pot is located at the inside of column by the utility model, and nitrogen balance cylinder is hidden in main spindle box inside simultaneously, saves space, appearance looks elegant, structure is compacter.

Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the section plan of the built-in nitrogen balance device of vertical machining centre.
In figure: 1. column, 2. nitrogen pot, 3. nitrogen balance support, 4. nitrogen balance cylinder, 5. spindle box part, 6. oil pipe, 7. nitrogen pot support, 8. spindle motor, 9. line slideway.
Detailed description of the invention
The utility model is described in more detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The built-in nitrogen balance device of a kind of vertical machining centre as shown in Figure 1, comprise nitrogen pot 2, nitrogen balance support 3, oil pipe 6 and nitrogen balance cylinder 4, described nitrogen pot 2 is fixedly mounted in column 1 by nitrogen pot support 7, the oil-out of described nitrogen pot 2 is provided with the controlling organization controlling opening and closing, described nitrogen balance support 3 is fixedly mounted on the top of column 1, described nitrogen balance cylinder 4 is vertically arranged, described nitrogen balance cylinder 4 lower cylinders is fixedly mounted in spindle box part 5, the piston rod of described nitrogen balance cylinder 4 stretches out cylinder body and is fixedly connected with nitrogen balance support 3, described oil pipe 6 is communicated with the oil-out of nitrogen pot 2 and the top cylinder body of nitrogen balance cylinder 4.
During work, when being positioned at the rotating forward of the Z axis motor 8 on spindle box part 5 and driving spindle box part 5 to move up on line slideway 9, hydraulic oil in nitrogen pot 2 enters nitrogen balance cylinder 4, the compressed air on nitrogen balance cylinder 4 cylinder body top is discharged, this is the nitrogen expansion in nitrogen pot 2, hydraulic oil is pressed in nitrogen balance cylinder 4, thus creates the weight of the balancing main shaft box part 5 that upwards pressure;
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
