Embodiment
The mounting structure of motor driver of the present invention, using maximum intensity parts in the motor driver structural member---mainframe or cabinet bottom are as the load part of mounting bracket, and mounting bracket itself is an independent part, but itself and load parts flexible combination, thereby thoroughly changed single in the past mounting means.
In an embodiment of the mounting structure of a kind of motor driver of the present invention, this mounting structure comprises many group first installing holes 11 and at least two mounting brackets, and wherein each mounting bracket all can be fixed to arbitrary group first installing hole 11.
As shown in Figure 1, be provided with one group of first installing hole 11 at each side of mainframe 10, each is organized first installing hole 11 and comprises a plurality of screws.Wherein welding forms the side of mainframe 10 by the vertical bending of the main panel of mainframe 10 and in the joint.This structure had both guaranteed intensity, simplified the structure again and production technology.
As shown in Figure 3, each mounting bracket includes this mounting bracket is fixed to the first fixed structure of arbitrary group first installing hole 11 and second fixed structure that this mounting bracket is fixed to vertical plane (for example metope or electrical equipment shell).
In the present embodiment, each mounting bracket includes orthogonal first stationary plane 32 and second stationary plane 31, wherein first fixed structure is first through hole 33 and a bolt (not shown) corresponding with first installing hole 11 on first stationary plane 32, and second fixed structure is the fixing hole on second stationary plane 31.Wherein fixing hole can be hardy hole 34, prong 35 and/or circular hole 36.
Can mounting bracket be fixed to the shell of metope or electrical equipment by expansion bolt/screw etc.For example mounting bracket is fixed, perhaps the hardy hole 34 of mounting bracket or prong 35 are articulated to predetermined fixed to the screw of metope etc. by the screw that passes circular hole 36.
The mounting structure of motor driver of the present invention only is not only applicable to the control box with mainframe, and can be applied to the control box with cabinet, as shown in Figure 4.Cabinet among this embodiment as shown in Figure 2, this cabinet 20 be located at outside and its side of mainframe 10 be provided with mainframe 10 on first installing hole, 11 corresponding second through hole 22, promptly respectively be provided with one group of second through hole 22 surrounding on three sides of mainframe 10, thereby can mainframe 10 and cabinet 20 be fixed by the bolt that passes second through hole 22 and be engaged to first installing hole 11 of mainframe 10.Simultaneously, also bolt can be passed first through hole 33, second through hole 22 on the cabinet 20 on the mounting bracket and be engaged to first installing hole 11 of mainframe 10, thereby mounting bracket and control box are fixed.
In addition, also can respectively be provided with near the bottom panel place on the upper panel of the cabinet 20 of motor driver and the downside panel one group with mounting bracket on the second corresponding installing hole 21 of first through hole 33.This second installing hole 21 can be self-clinching nut on the side panel or bloated riveting nut.The bottom panel that above-mentioned self-clinching nut or bloated riveting nut can be positioned at the cabinet 20 of motor driver makes progress on the part that vertically extending forms.
The mounting structure of above-mentioned motor driver can adapt to multiple installation scene, can thoroughly change single in the past mounting means.In actual installation, the mounting structure of this motor driver can be realized mounting means more than five kinds, and the centre-to-centre spacing of these several mounting meanss is basic identical, and the user can realize two to three kinds of installation methods with one group of installation position.Thereby satisfied the different installation of different occasions.For example:
(1) using two prongs on mounting bracket second stationary plane to mix two circular holes installs.Under this mode, adopt be positioned at motor driver cabinet about in the of 20 two mounting brackets 30 install.During installation, two screws (stay enough gap) of elder generation below metope or device housings prepackage, then two prongs of the mounting bracket 30 of below are placed on two screws of prepackage with the support motor drive unit weight, and at two circular hole mounting screws of upside mounting bracket 30, at last with four fastening getting final product of screw.
(2) two hardy holes of use upside mounting bracket 30 are joined the two hardy holes realization installation of downside mounting bracket 30.In this mode, elder generation is at two screws (staying enough gaps) of metope or device housings prepackage upside, hardy hole with upside mounting bracket 30 hangs on these two screws then, and stamps two screws at the straight body groove of the hardy hole of downside mounting bracket 30, last urgent four screws up and down.
(3) the straight body groove of two hardy holes of use upside mounting bracket 30 is joined the straight body groove of two hardy holes of downside mounting bracket 30.Under this mode, load onto four screws (staying enough gaps) in advance earlier, four hardy holes with the upper and lower sides support body hang on four screws then, laterally move to straight body groove, last urgent four screws up and down.
(4) two circular holes of use upside mounting bracket 30 cooperate two circular holes of downside mounting bracket 30.Under this mode, directly hold the cabinet 20 of motor driver, and at direct urgent four mounting screws of the circular hole of upper and lower sides mounting bracket 30.
(5) use the mounting bracket 30 of the left and right sides to install.Under this mode, load onto four screws (staying enough gaps) in advance earlier, the hardy hole with left and right sides mounting bracket 30 hangs on four screws then, utilizes the deadweight of motor driver to allow it slip into straight body groove, last urgent four mounting screws.
More than five kinds of mounting meanss be five kinds of modes commonly used, when concrete the use, support body itself can also have the combination (can use when installing for example two hardy holes join down two circular holes or directly install with four circular holes) of a variety of rooms installation dimension.And in actual use, mounting bracket is not limited to two, also can be more.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
