Embodiment
Referring to the accompanying drawing that the embodiment of the present invention is shown, hereinafter the present invention will be described in more detail.Yet the present invention can be with many multi-form realizations, and should not be construed as the restriction of the embodiment be subject in this proposition.On the contrary, it is abundant and complete open in order to reach proposing these embodiment, and makes those skilled in the art understand scope of the present invention fully.In these accompanying drawings, for clarity sake, may amplify size and the relative size in layer and zone.
Can see intuitively that satellite load complete machine has inner/outer drum structure in the test of the satellite load overall dynamic-balance of Fig. 1 and counterweight window view, outside loaded cylinder 6 and inner rotary cylinder 1, have certain gap between the two.In addition, have a fenestella on loaded cylinder 6, the size of fenestella is similar to balancing weight 7, therefore can't free-hand complete independently counterweight operate, and the risk that causes securing member to fall is arranged, therefore often need two to three technician's compounding practices, and the subsidiary function that apparatus of the present invention play just can address this problem well.
As shown in Figure 2, a kind of satellite load overall dynamic-balance counter-weight assist device of the present invention, its primary structure comprises: counterweight support 2, fixed support plate 3, rubber slab 9, wherein: counterweight support 2 comprises a U-shaped plate 10, and with the vertical stator 11 be connected of these U-shaped plate 10 bottom outside, and the place face of stator 11 is extensions of U-shaped plate 10U profile.
Control tolerance range during counterweight support 2 design, and guarantee support two cambered surfaces can with loaded cylinder 6 laminatings, then snap on loaded cylinder 6 outer walls, specific as follows:
The shape of stator 11 becomes an arc, and its radian is consistent with the radian of loaded cylinder 6 outer walls, and like this, after device of the present invention installs, U-shaped plate can fit tightly with loaded cylinder 6 outer walls, reaches good fixed effect; U-shaped plate 10 bottoms are away from the one side of described stator 11 also camber, its radian is consistent with the radian of loaded cylinder 6 outer walls, such structure is to consider between loaded cylinder 6 and rotary cylinder 1 to have certain gap, be fixed on that counterweight support 2 on loaded cylinder 6 also should guarantee and rotary cylinder 1 between corresponding gap length.
U-shaped plate 10 sidepieces snap in the window of loaded cylinder 6, then by holding screw 5, stator 11 are connected with loaded cylinder 6 outer walls, make device of the present invention can be fixed on loaded cylinder 6.
Fixed support plate 3 is arranged on two sidepieces of U-shaped plate 10 by holding screw 4, and link position is near the mid point of two sidepieces.Also be provided with through hole on fixed support plate 3; The gib screw 8 be arranged in through hole supports balancing weight 7 by the craft thread that connects balancing weight 7.Concrete, the through hole two ends are respectively arranged with nut, by the both sides nut, screw the gib screw 8 in through hole is fixed on fixed support plate 3.
Rubber slab 9 is connected to the inboard of described U-shaped plate 10 bottoms, and rubber slab 9 contacts with rotary cylinder 1 away from the one side of stator 11, and camber, radian is consistent with rotary cylinder 1 outer wall, such structural design is when carrying out counterweight work, add the friction force between university degree device and rotary cylinder 1, effectively reduce the relative displacement between rotary cylinder 1 and loaded cylinder 6, make both remain on as far as possible a relatively static state, the support effect of cooperation to balancing weight 7, effectively improve the Efficiency and accuracy of counterweight operation.
With regard to the erection sequence of this device, at first, holding screw 5 is screwed in the threaded hole of stator 11 in counterweight supports 2, until can not screw in, holding screw 5 is withstood on loaded cylinder 6, complete fixing.Secondly, a side is made to the rubber slab 9 with rotating cylinder 1 cambered surface consistent size, stick on counterweight support 2 along rotating cylinder 1 edge, reach and prevent the fastening function of falling.Then, gib screw 8 is passed in to fixed support plate 3 by after ectocentral through hole, screw in the craft thread hole of balancing weight 7, balancing weight 7 is fitted in to assigned address, finally gib screw 8 is fixed on fixed support plate 3 by four pieces of nuts front and back, the position of fixed weight piece whereby, complete the fitting operation of whole device.
When the fitting operation completed this device, by this device, the position of balancing weight 7 is fixed easily, then with product screw, balancing weight 7 is carried out to tightening, realized the beneficial effect that this device is wanted to play.Disassembly sequence gets final product according to counter the pushing away of above-mentioned erection sequence.
Because should be understood that the present invention, those skilled in the art can realize not breaking away from the spirit or scope of the present invention with many other concrete forms.Although described embodiments of the invention, the present invention should be understood and these embodiment should be restricted to, make and change and revise within the spirit and scope of the invention that those skilled in the art can define as appended claims.
