Description
Technical field
The utility model belongs to machining equipment field, relates in particular to a kind of balancing device for main spindle box for numerical control landing milling process bed.
Background technology
Numerical control landing milling process bed is superduty lathe, 10 tons of very heavy, light left and right of main spindle box quality of moving on column, and heavy reaches 30 tons.Main spindle box is in motion process; frequent meeting is disequilibrium because of the transfer of center of gravity, thereby between column guide rail end face and backboard, produces very large frictional force, and not only column guide rail produces very large disturbing moment; also affect product quality, be therefore necessary for main spindle box configuration counterweight.In prior art, China Patent No. " 201220193460.7 " discloses a kind of numerical control landing milling process bed gravity balance device, its open day is on December 19th, 2012, its technical scheme is that described gravity balance device comprises counterweight, described counterweight is positioned at the column of numerical control landing milling process bed, and described counterweight is connected with load pulley system.In actual use, counterweight is connected with main spindle box by steel cable, but does not establish protective device in this patent, once steel rope breaking, counterweight comes off, and the counterweight of 10 tons of weighing will damage milling-boring machine.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, a kind of balancing device for main spindle box for numerical control landing milling process bed is provided, the utility model can cushioning balance after steel rope breaking the falling speed of hammer, prevent that milling-boring machine from damaging, and improves the safety in utilization of equipment.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of balancing device for main spindle box for numerical control landing milling process bed, it is characterized in that: comprise counterweight, fixed pulley, steel cable, bracing wire, crossbeam and buffer unit, described counterweight is movably arranged in column, described crossbeam is fixed on the column top of milling-boring machine, described fixed pulley is fixed on crossbeam, one end of described steel cable is fixed on counterweight, the other end is fixed on main spindle box by fixed pulley, one end of described bracing wire is fixed on crossbeam, the other end is fixed on counterweight, and the height sum of the length of bracing wire and counterweight is less than the height of column, described buffer unit is fixedly installed in the column of counterweight below.
Described buffer unit comprises the spring that rubber layer and Duo Gen evenly arrange, and described spring is fixed on column bottom, and described rubber layer is fixed on spring top.
Described bracing wire is two, and two bracing wires are symmetrically distributed in steel cable both sides.
On described crossbeam, offer through hole, the end of described steel cable is connected with main spindle box through through hole, and is fixedly welded with the stopper that external diameter is greater than through hole internal diameter on this end.
Employing the utility model has the advantage of:
One, in the utility model, owing to being fixedly installed bracing wire between counterweight and crossbeam, and the height sum of the length of bracing wire and counterweight is less than the height of column, therefore when there is fracture in steel cable, bracing wire can drop to column bottom at counterweight, and milling-boring machine is produced and holds in time counterweight while clashing into; Because counterweight below is fixedly installed buffer unit, therefore, when fracture appears in steel cable, by buffer unit, not only can avoid counterweight directly to clash into column bottom again, can also reduce the moment maximum weighted of bracing wire, be conducive to the permanent use of bracing wire.Above-mentioned two kinds of respective outer side edges can provide duplicate protection to milling-boring machine; not only can cushioning balance after steel rope breaking the falling speed of hammer; the impulsive force that counterweight can also be declined is distributed to whole milling-boring machine, can effectively prevent that milling-boring machine from damaging, and improved the safety in utilization of equipment.
Two, in the utility model, described buffer unit comprises the spring that rubber layer and Duo Gen evenly arrange, described spring is fixed on column bottom, described rubber layer is fixed on spring top, this structure can be to counterweight equalizing and buffering, and the counterweight that can prevent upwards resilience tilts, effectively reduced the frictional force between counterweight and column.
Three, in the utility model, by two symmetrical bracing wires, can after steel rope breaking, hold firmly, evenly counterweight, can effectively improve the safety in utilization of milling-boring machine.
Four, in the utility model; the stopper that is greater than through hole internal diameter by the through hole on crossbeam and external diameter coordinates; can be after the fracture of the junction of steel cable and main spindle box; the stopper of steel cable end is stuck on crossbeam; prevent that counterweight from directly descending drop impact milling-boring machine; thereby milling-boring machine is formed to triple protection, further promoted the safety in utilization of milling-boring machine.
