The concrete meaning of language in the present invention.
The drag force of balancing gravity obliquely is provided to slide unit to execute end by balance cylinder, solves background technique
Middle ramp because the work caused by self gravity into or work move back when creep, migration technology problem.A kind of oblique slide unit weight is provided
Dynamic balance relief arrangement, (referring to fig. 2), which has, is driven the slide unit 2 being displaced in inclined planar linear by servo motor 1, (in conjunction with
Fig. 1) Fig. 1 embodiment is the schematic diagram that the present invention installs application in the double spindle numerical control machine tools of oblique lathe bed, wherein needs to illustrate
It is；Slide unit 2 is the slide unit (being not limited to 45 ° of inclination degrees) of oblique 45 ° of embodiments；It is run obliquely or obliquely to offset slide unit 2
When, because all assemblies or mechanism that carry installation on slide unit creep to 2 displacement accuracy bring of slide unit, bias effect: especially
Work of the slide unit 2 in 45 ° of diagonal upward directions into or work move back when creep, bias effect: the slide unit 2 balance cylinder 3 that is connected is living
The work actuating station of stopper rod 301, and the dragging dynamic balance opposite with gravity direction to slide unit 2 by 3 piston rod 301 of balance cylinder
The gravity of 2 inclined linear of slide unit displacement influences；Specifically, when slide unit 2 is driven by slide unit servo motor 1, by ball-screw nut
Auxiliary driving along oblique 45 ° tilt embodiment 7 work of saddle into or work move back when, at the same time, by the central control unit of numerically-controlled machine tool
Control balance cylinder 3 starts to act: and the balance cylinder 3 to the drag force size of slide unit 2 according to carrying installation on slide unit
Obtained by all assemblies or the Gravity calculation of mechanism (such as Y-axis power head, Y-axis power head driving motor): it should be understood that by
All mechanism gravity carried in slide unit assembly and thereon are definite value；Therefore the drag force of balance cylinder more favorably simplifies and calculates
Obtain, no matter 2 work of slide unit into or work move back；Balance cylinder 2 it is constant always to the drag force size of 45 ° of slide unit obliquely and with
Gravity suffered by slide unit and thereon assembly, device and mechanism balances each other counteracting；To play slide unit 2 as in the plane by servo electricity
The effect of machine drive displacement.And the balance cylinder 3 is also connected with energy storage canister 4 as the gas supply of balance cylinder 3.It wherein, is elimination gas
The influence of temperature variation, guarantee its more stable reliably operation: the built-in gas of the energy storage canister 4 is inert gas.It is logical
The installation that simple structure realizes balance cylinder 3 is crossed, and favorably simplifies balance cylinder 3 and pulls execution pulling force obliquely to slide unit
Calculate: the balance cylinder 3 is by cylinder fixed support 5 in the fixed support installation of slide unit saddle 7；Embodiment shown in Figure 2；
The fixed bracket 5 is L-type structure；And fixed 5 one end of bracket supports and the cylinder body for the cylinder that is connected, the other end is connected saddle 7；And
The linear displacement direction of the work of balance cylinder 3 actuating station is arranged in parallel with 2 linear displacement direction of slide unit, to simplify Balance Air
Cylinder 3 pulls the calculating for executing pulling force to slide unit obliquely.Such as when slide unit inclined direction is 60 °；Piston rod 301 executes displacement side
60 ° are similarly to the inclination angle of relative level.And the balance cylinder 3 is not limited to be mounted on the implementation on saddle top
Example；In the case where space allows, it is also mountable to saddle lower part.In addition, to realize cylinder actuating station by simple structure
It is connected supporting plate 6 with the connection of slide unit: the slide unit 2；And it is connected the execution end of 3 piston rod 301 of balance cylinder by supporting plate 6.
The execution end of 6 one end of supporting plate connection, 2 other end of the slide unit connection piston rod 301.
Working principle；No matter slide unit 2 obliquely or shifts up；The piston rod 301 of the balance cylinder 3 is always to cunning
Platform 2 provides oblique 45 ° upwards for balancing the dragging equilibrant force of 2 gravity of slide unit influence.Wherein, the braking of the balance cylinder 3 by
The control of numerically-controlled machine tool central control unit is realized.
As it can be seen that the present invention on the direction of displacement of ramp by installing the balance cylinder connecting with slide unit；By flat
The piston rod of weighing apparatus cylinder provides the drag force for being used to balance slide unit gravity obliquely to the linear displacement of slide unit always；Make to tilt
The slide unit of installation, which is equivalent to, is driven linear displacement by servo motor in horizontal plane；Eliminate inclined slide unit is influenced by self gravity,
There is a phenomenon where creeping, speed is unstable, positioning accuracy offset；Improve machining accuracy；Improve slide unit servo motor performance；Accordingly mention
High servo motor efficiency；Extend servo motor service life.After installing balance cylinder with embodiment as shown in the figure, balance cylinder is living
Stopper rod pulls the balance drag force size of slide unit obliquely, according to the gravity of all assemblies carried on ramp and slide unit
It is calculated.In addition, the configuration of the present invention is simple；The existing electric control system of lathe is changed small；It is easy to accomplish；It can be in oblique lathe bed
Lathe is promoted and applied and is popularized.In addition, the inert gas of air accumulator of the present invention provides reliable guarantor for the stable operation of balance cylinder
