Embodiment
See the accompanying drawing that the embodiment of the present invention is shown, hereafter in more detail the present invention will be described.But the present invention can realize in many different forms, and should not be construed as by the restriction in the embodiment of this proposition.On the contrary, it is abundant and complete open in order to reach for proposing these embodiments, and makes those skilled in the art understand scope of the present invention completely.In these accompanying drawings, for clarity sake, may be exaggerated size and the relative size in layer and region.
Tested by the satellite load overall dynamic-balance of Fig. 1 and intuitively can have inner/outer drum structure to satellite load complete machine in counterweight window view, namely outside loaded cylinder 6 and inner rotary cylinder 1, have certain gap between the two.In addition, loaded cylinder 6 has a fenestella, the size of fenestella is similar to balancing weight 7, therefore cannot free-hand complete independently weighting operation, and have the risk causing securing member to fall, 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 auxiliary device of satellite load whole machine dynamic balance weight 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 the stator 11 that be connected vertical with this U-shaped plate 10 bottom outside, and the face, place of stator 11 is extensions of U-shaped plate 10U profile.
Control tolerance range when counterweight support 2 designs, and ensure that two cambered surfaces of support can be fitted with loaded cylinder 6, then snap on loaded cylinder 6 outer wall, specific as follows:
The shape of stator 11 becomes an arc, and its radian is consistent with the radian of loaded cylinder 6 outer wall, and like this, after device of the present invention installs, U-shaped plate can fit tightly with loaded cylinder 6 outer wall, reaches good fixed effect; Away from the one side also camber of described stator 11 bottom U-shaped plate 10, its radian is consistent with the radian of loaded cylinder 6 outer wall, such structure considers to have certain gap between loaded cylinder 6 and rotary cylinder 1, and the counterweight support 2 be fixed on loaded cylinder 6 also should ensure gap length corresponding between rotary cylinder 1.
U-shaped plate 10 sidepiece snaps in the window of loaded cylinder 6, then is connected with loaded cylinder 6 outer wall by stator 11 by holding screw 5, and 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.Fixed support plate 3 is also provided with through hole; The gib screw 8 be arranged in through hole supports balancing weight 7 by the craft thread connecting balancing weight 7.Concrete, through hole two ends are respectively arranged with nut, are fixed on fixed support plate 3 by the gib screw 8 in through hole by both sides nut.
Rubber slab 9 is connected to the inner side bottom described U-shaped plate 10, 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, when such structural design is in order to make counterweight work carry out, add the friction force between university degree device and rotary cylinder 1, namely the relative displacement between rotary cylinder 1 and loaded cylinder 6 is effectively reduced, both are made to remain on the state of a geo-stationary as far as possible, coordinate the support effect to balancing weight 7, effectively improve the Efficiency and accuracy of weighting operation.
With regard to the erection sequence of this device, first, holding screw 5 is screwed in the threaded hole of stator 11 in counterweight support 2, until can not screw in, holding screw 5 is withstood on loaded cylinder 6 completes fixing.Secondly, side is made the rubber slab 9 consistent with rotating cylinder 1 arc sizes, be pasted onto on counterweight support 2 along rotating cylinder 1 edge, reach and prevent the fastening function fallen.Then, gib screw 8 is passed in 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 assigned address, finally gib screw 8 is fixed on fixed support plate 3 by before and after four pieces of nuts, the position of fixed weight block whereby, completes the installation operation of whole device.
Operating when completing the installation to this device, namely fixing conveniently by the position of this device by balancing weight 7, then with product screw, tightening being carried out to balancing weight 7, achieve this device beneficial effect for playing.Disassembly sequence then pushes away according to above-mentioned erection sequence is counter.
Because those skilled in the art should be understood that the present invention can not depart from the spirit or scope of the present invention with many other concrete forms realizations.Although describe embodiments of the invention, the present invention should be understood and should not be restricted to these embodiments, within the spirit and scope of the invention that those skilled in the art can define as appended claims, make change and amendment.
