Detailed description of the invention
In order to the technical solution of the utility model is explained further, below by specific embodiment, this utility model is entered
Row elaborates.
As shown in Figure 1-2, it is that 2 pairs, a kind of gantry machining center main shaft cabin compensating cylinder counterweight that this utility model discloses is tied
Structure, including including saddle 1, main shaft cabin 2, balance cylinder 3 and feeder.
Saddle 1 is fixedly mounted in lathe (not shown), and main shaft cabin 2 is arranged on saddle in the mode of can slide up and down
On 1, this structure is the existing normal structure of gantry machining center, no longer specifically describes at this.
Balance cylinder 3 is installed between saddle 1 and main shaft cabin 2, is supplied to 2 one, main shaft cabin and master by balance cylinder 3
Axle cabin 2 gravity upwards equilibrant of the same size.Preferably, saddle 1 is provided with lower carriage 11, and the cylinder barrel 31 of balance cylinder 3 is pacified
It is contained on lower carriage 11.Upper end, main shaft cabin 2 is provided with upper bracket 21, and the piston rod 32 of balance cylinder 3 is arranged on upper bracket 21.
Wherein balance cylinder 3 has two, and the balance cylinder of two same model is symmetrically mounted on the both sides in main shaft cabin 2, to ensure to be subject to
Power is uniform.
Owing to the piston rod 32 of balance cylinder 3 need to move with main shaft cabin 2 and moves, then in the cylinder barrel 31 of balance cylinder 3
Air pressure will change, for avoiding the generation of this situation, balance cylinder 3 is connected with feeder by high-voltage tube 4, preferably supplies
Device of air is air accumulator 5.
The intake method of balance cylinder 3, as shown in Figure 3 and Figure 4, piston rod 32 is hollow structure, and piston rod 32 top is opened
If pipe screw thread 321, the upper end of piston rod 32 is fixedly mounted by pipe joint 6 and high-voltage tube 4, the gases at high pressure work by this hollow
Stopper rod 32 enters in cylinder barrel 31.
Wherein air accumulator 5 has two gas outlets 51 that air pressure is consistent, and above-mentioned two balance cylinders 3 are by high-voltage tube 4 respectively
Connect with in two gas outlets 51.Air accumulator 5 has the adjusting means 52 adjusting QI KOU 51 air pressure size, by regulation
Device 52 preconditioning two balance cylinder 3 gives the size of main shaft cabin 2 upward force, it is ensured that the size of this power and main shaft cabin 2 gravity one
Cause.
During the work of whole device, when 2 descending motion of main shaft cabin, piston rod 32 declines, and the volume in cylinder barrel 31 diminishes pressure
Power will become big, during gas is pressed back into air accumulator 5 in cylinder barrel 31, to ensure stablizing of cylinder barrel 31 internal gas pressure；Otherwise on main shaft cabin 2
When rising motion, piston rod 32 rises, and cylinder barrel 31 internal volume becomes big pressure and will decline, and in air accumulator 5, gas is supplemented in cylinder barrel in time
In 31, to ensure stablizing of cylinder barrel 31 internal gas pressure, reach pressure balance.
Owing to parts machining and installation unavoidably producing error, make piston rod 32 uneven with the track in main shaft cabin 2
OK, causing vibrations and extruding phenomenon, also result in balance cylinder 3 and damage, for avoiding the generation of this phenomenon, the present embodiment uses as follows
The mounting means of balance cylinder 3.
As it is shown on figure 3, the installation of cylinder barrel 31.Cylinder barrel 31 outer wall has horizontal pivot spindle 311, and lower carriage 11 has pivoted hole
111, cylinder barrel 31 is arranged on pivoted hole 111 by horizontal pivot spindle 311, makes the cylinder barrel 31 can be around horizontal pivot spindle 311 at lower
Rotate at frame 11.
As shown in Figure 4, the installation of piston rod 32.Piston rod 32 is installed on support 21, specifically by bearing with spherical outside surface 7
, the axis hole 211 installed for bearing with spherical outside surface 7 offered by upper bracket 21, and the outer ring of bearing with spherical outside surface 7 is placed in axis hole 211, outer ring
Fixed by the bearing cap 212 being fixed on upper bracket 21.The inner ring of bearing with spherical outside surface 7 is arranged on piston rod 32, piston rod
32 offer external screw thread 322, and external screw thread 322 is provided with locking nut 8, complete the fixing of inner ring by screwing in locking nut 8.Make to live
The upper end of stopper rod 32 can rotate.
After this installs, once piston rod 32 is not parallel with the track in main shaft cabin 2, by balancing the horizontal pivot joint of cylinder barrel 31
Bearing with spherical outside surface 7 on axle 311 and piston rod 32, balance cylinder 3 can adjust angle automatically, eliminates because of the shake of not parallel generation
Move and extruding phenomenon, the robust motion in lifting spindle cabin 2, improve the service life of balance cylinder 3.
The present embodiment owing to carrying out the weight in balancing main shaft cabin 2 by balance cylinder 3, when the most there is not the operating of existing sprocket wheel
The most adjoint sudden change power, has the advantages that response characteristic is good, it is adaptable to high-speed cutting, and good operating stability can extend ball wire
Thick stick and the service life of motor, promote machining accuracy and fineness, and the noise sent without sprocket wheel operating.
These are only preferred embodiment of the present utility model, the not restriction to protection domain of the present utility model.All depend on
The equivalent variations that the mentality of designing of this case is done, each falls within the protection domain of this case.
