Abstract
The utility model relates to a headstock hydraulic pressure balancing unit. Main solve the current boring machine headstock balancing unit that mills in that headstock weight is big, the impact force made the cracked problem of connecting piece greatly and easily when feed rate was high. Its characterized in that: stand (4) top is fixed with chain pulley seat (2), and there is the sprocket at the both ends of chain pulley seat (2) through the hub connection respectively, and wherein right -hand member sprocket (11) bottom corresponds headstock (8), stand (4) left bottom is fixed with hydro -cylinder seat (10), and hydro -cylinder seat (10) vertical direction is corresponding with left end sprocket (1), and hydro -cylinder seat (10) upper portion is fixed with hydro -cylinder (6), and through lug (9) closing plate (5) on the piston rod of hydro -cylinder (6), both ends were fixed respectively on chain pulley seat (2) bottom and headstock (8) upper portion after left and right sprocket and lug were walked around in link joint (5). This hydraulic pressure headstock balancing unit impact force is little, and the noise is low, can avoid the connecting piece fracture, avoids the lathe impaired.
Description
Technical field
The utility model relates to mechanical field, specifically a kind of main spindle box hydraulic balance device.
Background technology
What current milling-boring machine balancing device for main spindle box adopted usually is casting counterweight because casting counterweight cost is low, good processability, the process-cycle is short, and equilibrant force is stablized, but its to be only only applicable to main spindle box weight less, the situation that feed speed is lower.When main spindle box weight is larger, when feed speed is higher, the acceleration starting main spindle box is also very large, cause noise and inertia force very large, if at this time adopt casting counterweight can produce noise and impulsive force, if things go on like this, the steel wire rope of connection main spindle box and counterweight or carrier bar can be made to produce tired, steel wire rope or carrier bar rupture in advance, cause lathe impaired, even Personal Risk occur.
Summary of the invention
In order to overcome, existing milling-boring machine balancing device for main spindle box is large in main spindle box weight, feed speed height time the impulsive force deficiency that makes greatly and easily connector rupture, the utility model provides a kind of main spindle box hydraulic balance device, this main spindle box hydraulic balance device impulsive force is little, noise is low, connector can be avoided to rupture, avoid lathe impaired.
The technical solution of the utility model is: a kind of main spindle box hydraulic balance device, comprises column, main spindle box, and described column top is fixed with chain pulley seat, and the two ends of chain pulley seat are connected with sprocket wheel respectively by axle, wherein corresponding main spindle box bottom right-hand member sprocket wheel; Bottom on the left of described column is fixed with oil cylinder seat, oil cylinder seat vertical direction is corresponding with left end sprocket wheel, and oil cylinder seat top is fixed with oil cylinder, the piston rod of oil cylinder connects carrier bar by hanger, and after described carrier bar walks around left and right sprocket wheel and hanger, two ends are separately fixed at bottom chain pulley seat and main spindle box top.
Be fixed with left chain seat bottom described chain pulley seat left end, main spindle box top is fixed with right chain seat, and described carrier bar two ends are separately fixed on left chain seat and right chain seat.
The utility model has following beneficial effect: owing to taking such scheme; column top is fixed with chain pulley seat; after sprocket wheel walked around by carrier bar, main spindle box and oil cylinder are connected; like this when main spindle box moves up and down; the piston of oil cylinder together does stretching motion with this, makes main spindle box be in poised state all the time, reduces impulsive force and noise; avoid carrier bar to rupture, thus protect lathe.

1-left end sprocket wheel in figure, 2-chain pulley seat, the left chain seat of 3-, 4-column, 5-carrier bar, 6-oil cylinder, the right chain seat of 7-, 8-main spindle box, 9-hanger, 10-oil cylinder seat, 11-right-hand member sprocket wheel.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By shown in Fig. 1 to Fig. 3, a kind of main spindle box hydraulic balance device, comprise column 4, main spindle box 8, described column 4 top is fixed with chain pulley seat 2, and chain pulley seat 2 is strip, and one end is positioned at main spindle box 8 top, the other end stretches out column 4, the two ends of chain pulley seat 2 are connected with sprocket wheel respectively by axle, wherein corresponding main spindle box 8 bottom right-hand member sprocket wheel 11, and left end sprocket wheel 1 stretches out column 4.Bottom on the left of described column 4 is fixed with oil cylinder seat 10, and oil cylinder seat 10 vertical direction is corresponding with left end sprocket wheel 1, and oil cylinder seat 10 top is fixed with oil cylinder 6, and the piston rod of oil cylinder 6 connects carrier bar 5 by hanger 9.Be fixed with left chain seat 3 bottom described chain pulley seat 2 left end, main spindle box 8 top is fixed with right chain seat 7, and after carrier bar 5 walks around left and right sprocket wheel and hanger, two ends are separately fixed on left chain seat 3 and right chain seat 7.
When main spindle box 8 does vertical feed along column 4 guide rail, the piston of oil cylinder 6 moves both vertically along cylinder barrel, main spindle box 8 is made to be in poised state all the time, due to the friction that the friction between the piston of oil cylinder 6 and cylinder barrel is between metal and rubber seal, it is flexible contact, frictional force is very little, although main spindle box weight is very large, feed speed is very high, also can not produce noise, even if when main spindle box 8 just starts from inactive state, the acceleration of main spindle box 8 is very large, inertia force is very large, and hydraulic oil turnover oil cylinder also can not produce impulsive force and noise, avoids carrier bar to rupture.And the oil cylinder in this device is arranged on outside column, be convenient to install, observe and adjustment.
Claims (2)
1. a main spindle box hydraulic balance device, comprise column (4), main spindle box (8), it is characterized in that: described column (4) top is fixed with chain pulley seat (2), the two ends of chain pulley seat (2) are connected with sprocket wheel respectively by axle, wherein right-hand member sprocket wheel (11) the corresponding main spindle box in bottom (8); The bottom in described column (4) left side is fixed with oil cylinder seat (10), oil cylinder seat (10) vertical direction is corresponding with left end sprocket wheel (1), and oil cylinder seat (10) top is fixed with oil cylinder (6), the piston rod of oil cylinder (6) connects carrier bar (5) by hanger (9), and after described carrier bar (5) walks around left and right sprocket wheel and hanger, two ends are separately fixed at chain pulley seat (2) bottom and main spindle box (8) top.
