The invention relates to a fixing structure for a nitrogen gas balancing cylinder, which comprises a machine tool column, a balancing cylinder and a nitrogen gas bottle, wherein the balancing cylinder is communicated with the nitrogen gas bottle through an oil tube; a pull rope reversing mechanism is arranged at the top of the column; the balancing cylinder is vertically arranged in the column; the balancing cylinder is connected with a main spindle box of a machine tool through a pull rope which is wound around the pull rope reversing mechanism; and a piston rod of the balancing cylinder extends downwards and is fixed on the column. According to the invention, the balancing cylinder is arranged in the machine tool column and is connected with the main spindle box through the pull rope reversing mechanism, so that the height of the whole machine tool can not be increased.
Description
Technical field
The present invention relates to the main shaft counterweight nitrogen balance system of lathe class machining center, specifically a kind of fixed structure of nitrogen balance oil cylinder.
Background technology
The nitrogen balance system of lathe class machining center has substituted traditional main shaft balancing weight counterweight, has both reduced raw-material resource loss, has reduced the gross weight of lathe, has also reduced the microseismic activity that motion of main shaft produces simultaneously, has improved Product Precision.
Oil cylinder in the nitrogen balance system generally is installed in the machine pillar top, and its piston rod stretches out downwards and is connected with main spindle box.This mounting means of balancing cylinder has increased the whole height of lathe, causes the setting height(from bottom) of lathe to increase, and has limited lathe and has used in the limited occasion of spatial altitude.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of fixed structure of nitrogen balance oil cylinder is provided, this fixed structure can not increase the whole height of lathe.
According to technical scheme of the present invention: a kind of fixed structure of nitrogen balance oil cylinder, comprise machine pillar, balancing cylinder and nitrogen cylinder, described balancing cylinder is connected with described nitrogen cylinder by oil pipe, the top layout of described column has the drag-line changement, described balancing cylinder vertically is arranged in the described column, described balancing cylinder links to each other with the main spindle box of lathe by behind the described drag-line changement of guy cable rounds, and the piston rod of described balancing cylinder stretches out downwards and is fixed on the described column.
The piston rod of described balancing cylinder links to each other with described column by universal joint.
Described balancing cylinder is suspended under the hanger, and described hanger is fixed on below the connector, and described connector links to each other with described drag-line.
Described hanger comprises the fixed head that is fixed on below the described connector, be fixed with the otic placode perpendicular with described fixed head on the face of described fixed head, have the otic placode connection holes on the described otic placode, described otic placode links to each other with described balancing cylinder by the connector that passes described otic placode connection holes.
Have the fixed head connection holes on the described fixed head, described fixed head links to each other with described connector by passing described fixed head connection holes.
Technique effect of the present invention is: the present invention is arranged in balancing cylinder in the machine pillar, and links to each other with main spindle box by the drag-line changement, can not increase the whole height of lathe; Balancing cylinder links to each other with the drag-line changement by hanger and connector, and is easy for installation.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the perspective view of the hanger among the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Among Fig. 1, Fig. 2, comprise connector 1, hanger 2, otic placode connection holes 21, otic placode 22, fixed head connection holes 23, fixed head 24, balancing cylinder 3, piston rod 4, universal joint 5, column 6, nitrogen cylinder 7 etc.
As shown in Figure 1, the present invention is a kind of fixed structure of nitrogen balance oil cylinder, comprises machine pillar 6, balancing cylinder 3 and nitrogen cylinder 7, and balancing cylinder 3 is connected with nitrogen cylinder 7 by oil pipe.
The present invention has the drag-line changement in the top layout of column 6, and the drag-line changement can adopt fixed pulley.Balancing cylinder 3 vertically is arranged in the column 6, and balancing cylinder 3 links to each other with the main spindle box of lathe by behind the guy cable rounds drag-line changement, and the piston rod 4 of balancing cylinder 3 stretches out downwards and is fixed on the column 6.
The piston rod 4 of balancing cylinder 3 can link to each other with column 6 by universal joint 5.
Balancing cylinder 3 can link to each other with the drag-line changement by hanger 2 and connector 1.Balancing cylinder 3 is suspended in hanger 2 times, and hanger 2 is fixed on below the connector 1, and connector 1 links to each other with drag-line.
As shown in Figure 2, hanger 2 comprises the fixed head 24 that is fixed on below the connector 1, be fixed with the otic placode 22 perpendicular with fixed head 24 on the face of fixed head 24, have otic placode connection holes 21 on the otic placode 22, otic placode 22 links to each other with balancing cylinder 3 by the connector that passes otic placode connection holes 21.
Fixed head 24 can directly be welded on below the connector 1, also can have fixed head connection holes 23 at fixed head 24, and fixed head 24 links to each other with connector 1 by passing fixed head connection holes 23.
The course of work of the present invention is as follows: when the main spindle box of lathe rises, the valve open of nitrogen cylinder 7 makes the high compression swelling of nitrogen gas generation, and the hydraulic oil in the nitrogen cylinder 7 flows into balancing cylinder 3 under the pressure-acting of high pressure nitrogen, cylinder barrel is moved downward, the balancing main shaft case; When the main spindle box of lathe descended, the hydraulic oil in the balancing cylinder 3 refluxed, and cylinder barrel moves downward, the balancing main shaft case.
The present invention is arranged in balancing cylinder 3 in the machine pillar 6, and links to each other with main spindle box by the drag-line changement, can not increase the whole height of lathe; Balancing cylinder 3 links to each other with the drag-line changement by hanger 2 and connector 1, and is easy for installation.
