Abstract
The utility model relates to a lift plate milling machine lift automatic balance device, which consists of a friction clutch and a one-way clutch, and is characterized in that the friction clutch consists of friction pieces and an outer ring, and the one-way clutch consists of an outer ring, a star wheel, a spring and a pin roller; the friction clutch and the one-way clutch are fixed in a shell through a gland and a bolt, the star wheel of the one-way clutch is fixed on a shaft, and the friction piece is fixed in the shell by a bolt. The friction piece is made of copper, and the outer ring and the star wheel are made of steel. The utility model can effectively reduce the friction loss between the friction pieces and greatly prolongs the service life of the product.
Description
Technical field
The utility model relates to a kind of bascule, is specifically related to a kind of knee-and-column milling machine lifting automatic balancing arrangement.
Background technology
The automatic balancing arrangement of present lifting platform mainly contains friction clutch and mono-directional overrun clutch, and its operation principle is as follows: when bevel gear is rotated, drive the star-wheel of mono-directional overrun clutch by taper pin.When workbench rose, turning to of star-wheel was the direction that makes the shell disengagement of roller and freewheel clutch, and it is inoperative that shell does not change friction plate.When workbench descended, turning to of star-wheel made the roller wedge between the shell of star-wheel and freewheel clutch, and shell is along with bevel gear is rotated together.Produce relative motion between the interior friction plate that connects together through spline and shell and the fixing outside friction disc since between the interior outside friction disc by spring compression, certain frictional resistance is arranged, so the damping action of playing, the strength of rising and decline is able to balance.Because interior outside friction disc is in running order for a long time, and it is bigger to wear and tear, need often to change in the milling machine work.
The utility model content
The utility model has been researched and developed a kind of knee-and-column milling machine lifting automatic balancing arrangement at above-mentioned weak point, and purpose is.
Technical solution of the present utility model:
A kind of knee-and-column milling machine lifting automatic balancing arrangement is made of friction clutch and mono-directional overrun clutch, and it is characterized in that: friction clutch is made of friction plate and outer shroud; Mono-directional overrun clutch is made of outer shroud, star-wheel, spring and roller.
Described friction clutch and mono-directional overrun clutch are fixed in the shell by gland and screw, and the mono-directional overrun clutch star-wheel is fixed on the axle, and friction plate is fixed in enclosure by screw.
The material of described friction plate is copper, and outer shroud and star-wheel material are steel.
The beneficial effects of the utility model: the design can reduce the frictional dissipation between the friction plate effectively, prolongs product service life greatly.
Description of drawings
Fig. 1 looks generalized section for the utility model master.
Fig. 2 is Figure 1A-A ' generalized section.
The specific embodiment
As shown in Figures 1 and 2, friction clutch and mono-directional overrun clutch are fixed in the shell 1 by gland 9 and screw 10, mono-directional overrun clutch star-wheel 5 is fixed on the axle 8, and friction plate 3 is fixed in shell 1 inside by screw 11-1, and friction plate 2 is fixed in shell 1 inside by screw 11-2.
The specific embodiment: when workbench rose, star-wheel 5 clockwise rotated, and spring 6 shrinks, and roller 7 and freewheel clutch outer shroud 4 are thrown off, and outer shroud 4 does not change, and friction plate 2 and friction plate 3 are inoperative; When workbench descends, star-wheel 5 rotates counterclockwise, spring 6 diastoles, make roller 7 wedges between star-wheel 5 and freewheel clutch outer shroud 4, outer shroud 4 produces relative motion along with star-wheel 5 rotates together between outer shroud 4 and friction plate of fixing 2 and the friction plate 3, owing to compress by steel ball 12, spring 13 and screw 14 between outer shroud 4 and friction plate of fixing 2 and the friction plate 3, certain frictional resistance is arranged therebetween, so the damping action of playing, the strength of rise and fall is able to balance.
