The specific embodiment
In conjunction with Fig. 1 to Figure 18, preferred embodiment of the present invention is described in further details.
For a gripper type universal fixturing for gas cylinder valve handling, the parts that are mainly concerned with comprise shaft coupling 1, axis 2, paw drive unit upper cover 3, gear cap 4, company's blade tooth wheel seat 5, paw 6, connecting pin 7, paw fingerstall 8, paw fixed support 9, connect latch spring 11, paw drive unit housing 12, planetary gear 13, sun gear 14.
Shaft coupling 1 connects axis 2, when external motor (or motor, the present embodiment be take motor as example), along any direction, rotates, and can drive axis 2 by shaft coupling 1.Paw drive unit is arranged on axis 2, drives paw folding.Paw drive unit mainly comprises paw drive unit upper cover 3, gear cap 4, connects blade tooth wheel seat 5, paw drive unit housing 12 and cyclic train, and in the present embodiment, cyclic train is the transmission mechanism that planetary gear 13, sun gear 14 form.
Connect three planet wheel spindles that blade tooth wheel seat 5 upper ends have 120 degree to be arranged symmetrically with, mate gear lid 4 location fixedly planetary gear 13, sun gear 14 is set on axis 2, with three planetary gear 13 engaged transmission.Connect blade tooth wheel seat 5 and be arranged on paw drive unit housing 12 inside, on the inwall of paw drive unit housing 12, offer a circle gear ring 17, with planetary gear 13 engaged transmission.Connect blade tooth wheel seat 5 upper ends and be stamped gear cap 4, gear cap 4 has paw drive unit upper cover 3 above, covers in paw drive unit housing 12 upper ends.The lower end of paw drive unit housing 12 forms cam 16.The lower end that connects blade tooth wheel seat 5 connects by key 10 the paw fixed support 9 that is positioned at axis 2 lower ends.
Paw 6 comprises two of left and right, and the middle part of paw 6 is fixing with paw fixed support 9 by connecting pin 7, connects latch spring 11 simultaneously connect in the upper end of two paws 6 by spring, makes upper-end part of driving fit tightly the surface at cam 16.The circumferential profile of cam 16 is oval shape, and two orthogonal center line A, B are respectively beeline and longest distance.The lower end of paw 6 is overlapped respectively paw fingerstall 8.
The present invention is under off working state, when motor (or motor, the present embodiment be take motor as example) along any direction, rotate, by shaft coupling 1, drive axis 2, thereby drive the sun gear 14 in paw drive unit to rotate, paw drive unit adopts cyclic train to drive, and sun gear 14 rotates and drives three planetary gears 13 to rotate, and paw drive unit housing 12 is rotated.Shown in Fig. 1, Fig. 2, Fig. 6, Fig. 7, cam 16 and the motor of claw drive unit housing 12 lower ends rotate backward, and velocity of rotation is determined by epicyclic gearing ratio.Due to connect latch spring 11 guaranteed paw 6 upper ends all the time with cam laminating, and be revolute pair at connecting pin 7 places, thereby paw 6 can be done clamping alternately and unclamp motion along with the fit rotation of cam 16 of upper end.When paw 6 upper ends are fitted in cam 16 beeline A two ends, paw 6 lower ends refer to that spacing is maximum, as shown in figure 12; When paw 6 upper ends are fitted in cam 16 longest distance B two ends, paw 6 lower ends refer to that spacing is minimum, as shown in figure 13; When paw fingerstall 8 is mixed in paw 6 lower ends, clamping spacing can reach zero, as shown in figure 14.
Under the present invention in working order, suppose that cylinder valve to be loaded and unloaded is in place.Motor rotates along corresponding direction according to need of work, and paw 6 starts to clamp, and by the state 1 of Figure 15, forwards Figure 16 state 2 to.When the plane position of paw 6 lower ends and cylinder valve to be loaded and unloaded (in the market, nearly all cylinder valve has the plane position of similar tetragonal body or hexahedron), contact and clamp, paw drive unit is locked immediately, now whole fixture has and only has a rotary freedom, whole fixture will rotate together with cylinder valve, turn to consistent with turning to of motor, if Figure 16 state 2 is to Figure 17 state 3.When cylinder valve is tightened, motor starts reversion, paw drive unit reverse drive, and paw 6 unclamps gradually, if Figure 17 state 3 is to Figure 18 state 4, removes cylinder valve and completes the operation of dress valve.In like manner, oppositely can complete and unload valve operation.
Above-described embodiment is only for the inventive concept of the present invention of explaining, but not restriction to rights protection of the present invention, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should fall into protection scope of the present invention.
