Detailed Description

Referring now to the drawings, specific embodiments of the present invention will be described in detail. What has been described herein is merely a preferred embodiment in accordance with the present invention, and those skilled in the art will appreciate that other ways of implementing the present invention on the basis of the preferred embodiment will also fall within the scope of the present invention.

Fig. 1 to 4 show a mounting assembly according to a preferred embodiment of the present invention and a partial structure of a machine including the same.

The mounting assembly is used for fixing the target device 1 in the machine 12, and the target device 1 comprises a target device body and a target device mounting frame 2. The mounting assembly comprises a locking mechanism 9, a fixing frame 3 and an anti-rotation part 4. Wherein the locking mechanism comprises at least a first locking member 7. In the present invention, there is not necessarily a relationship between the terms "first" and "second", and the presence of "first" does not mean that "second" is necessarily present.

Referring to fig. 1 to 4, it can be seen that the mount 3 is fixedly disposed within the machine 12, and the target equipment mount 2 can be locked to the mount 3 by a locking mechanism. The fixing frame 3 comprises two side plates 32 opposite to each other and a connecting plate 31 located on top of the two side plates 32 and connected between the two side plates 32, in other words, the two side plates 32 are bent and protruded from the opposite ends of the connecting plate 31 to the same direction so that the fixing frame 3 forms a preferred U-shaped structure with an opening facing downwards. And, the connecting plate 31 is provided with a first through hole for the first locking member 7 to pass through.

The anti-rotation part 4 is provided with a second through hole, the anti-rotation part 4 can be positioned between the two side plates 32 and aligned with the first through hole, the first locking part 7 can penetrate through the first through hole and be engaged with the second through hole so that the anti-rotation part 4 and the connecting plate 31 can rotate relatively, and the maximum rotation radius of the anti-rotation part 4 is larger than the distance between the side plates 32 and the center of the first through hole in the rotation plane of the anti-rotation part 4, so that the anti-rotation part 4 can be prevented from further rotating relative to the connecting plate 31 due to interference between the anti-rotation part 4 and the side plates 32 in the locking process of the locking mechanism 9.

It can be understood that the rotation-preventing component 4 can rotate relative to the fixing frame 3 with the center of the second through hole as the center of the circle, and then the distance between any position on the rotation-preventing component 4 and the center of the circle in the rotation plane of the rotation-preventing component 4 can be referred to as the rotation radius, and the "maximum rotation radius" disclosed herein is the maximum value of the rotation radii.

It should also be noted that "the first securing member is capable of engaging the second through-hole" as disclosed herein encompasses two possible scenarios: the first locking member 7 is engaged with the second through hole through other parts in the second through hole, which is indirect engagement; the first locking member 7 directly engages the second through hole.

Specifically, in this embodiment, the target device 1 is a transmission, and the target device mounting bracket is a transmission mounting bracket. Preferably, the gearbox mounting brackets 2 are two, and the two target device mounting brackets 2 are oppositely arranged with respect to the main body of the gearbox 1 to ensure the stability of the installation of the target device 1. The number of the mounting assemblies is correspondingly two, and the two target equipment mounting frames 2 are respectively connected with the corresponding mounting assemblies through locking mechanisms 9.

With continued reference to fig. 1 and 2, it can be seen that when the mount 3 is locked with the target equipment mount 2, the target equipment mount 2 is located on the top side of the connection plate 31, and the rotation preventing member 4 is located on the bottom side of the connection plate 31. In addition, in this specification, directional terms "top side", "bottom side", "upward", "downward", and the like, which are used in the present embodiment, are relative to the state in which the respective components are shown in fig. 1, and thus these directions should be understood as a relative description rather than an absolute description. Wherein the "downward" direction is shown as D1 in FIG. 2 and the "upward" direction is shown as D2 in FIG. 2.

Meanwhile, in the present embodiment, a bolt is selected as the first locking member 7, and the locking mechanism 9 may further include a second locking member 8 which is a nut engaged with the bolt. Fig. 2 shows how the mounting assembly and the target device 1 are locked to each other by the locking mechanism 9.

To prevent the second locking member 8 from rotating, it can be welded into the second through hole of the rotation-preventing member 4. During the tightening of the first retaining member 7, the anti-rotation part 4 and the side plate 32 can interfere, and further rotation of the anti-rotation part 4 is prevented, as a result of which the second retaining member 8, which is fixed with respect to the anti-rotation part 4, cannot rotate, so that the first retaining member 7 can be tightened quickly.

Referring to fig. 4, for ease of assembly, the second through-hole may be shaped to conform to the outer shape of the second retaining member 8, i.e., the second through-hole is in form-fitting engagement with the second retaining member 8. For example, if a hexagonal nut is selected as the second locking member 8, the second through-hole is preferably formed as a hexagonal prism-shaped through-hole. When the rotation preventing part 4 is positioned between the two side plates 32, the second locking member 8 can receive the first locking member 7 which penetrates the target apparatus mounting frame 2 and the first through hole in sequence, and the first locking member 7 and the second locking member 8 are in threaded engagement, thereby achieving the assembly of the target apparatus 1.

In this embodiment, since the first locking member 7 is for engagement with the second locking member 8 in the second through hole, it is understood that the first locking member 7 is actually indirectly engaged with the second through hole. If it is desired to achieve a direct engagement of the first locking element 7 with the second through-hole, an internal thread can be made in the second through-hole of the rotation-preventing part 4, the first locking element 7 directly engaging with the internal thread of the second through-hole and achieving a locking, in which case the provision of the second locking element 8 can be omitted.

Preferably, referring to fig. 4, the thickness of the anti-rotation part 4 may be designed to be smaller than the height of the second locker 8 so that both the top surface and the bottom surface of the second locker 8 protrude out of the anti-rotation part 4 when the second locker 8 is fixed in the second through-hole. Such design can lighten the weight of the anti-rotation part 4 and save the production and manufacturing cost under the condition of ensuring enough connecting strength, and meanwhile, the anti-rotation part 4 is not easy to fall off due to the action of gravity after the installation is finished.

Further, on the basis of preventing the second locking member 8 from rotating, the fixing frame 3 and the rotation preventing member 4 may have various design structures.

For example, the connecting plate 31 and the side plate 32 of the fixing frame 3 may be a single member integrally formed, or may be a separate member assembled.

For another example, in the present embodiment, the link plate 31 of the fixing frame 3 is formed substantially in a rectangular shape having lateral and longitudinal edges that may correspond to the width and length directions of the rectangular shape, respectively, the lateral direction of the link plate 31 being shown by D4 in fig. 3, and the longitudinal direction being shown by D3 in fig. 3.

Further, two side plates 32 may be respectively connected to two lateral edges of the connecting plate 31 and the two side plates 32 are parallel to each other and are commonly perpendicular to the connecting plate 31, it can be understood that the distance between the first through hole and the side plate 32 is half of the longitudinal dimension of the connecting plate 31. Preferably, some relief notches 33 may be provided at the bottom of the side plates 32 of the fixed frame 3 to provide space for the installation of other components within the machine 12.

On the other hand, the rotation preventing member 4 may be formed in an elongated shape, and when the rotation preventing member 4 is correctly positioned at the bottom side of the connecting plate 31 with the rotation preventing member 4 being parallel to the connecting plate 31, the second through hole is provided near one end portion of the elongated shape (which will be referred to as the proximal end portion 41), then it will be understood that the maximum rotation radius of the rotation preventing member 4 at this time is the distance between the second through hole and the other end portion of the elongated shape (which will be referred to as the distal end portion 42 hereinafter).

For more intuitive description, the longitudinal and transverse dimensions of the connecting plate 31 are set to L and W, respectively, and the distance between the second through hole and the distal end portion 42 of the rotation-preventing member 4 is set to D, so when D > L/2 is satisfied, it can be ensured that the distal end portion 42 of the rotation-preventing member 4 interferes with the side plate 32 during tightening of the first lock member 7, so that the second lock member 8 cannot be further rotated.

More preferably, the rotation prevention can be performedThe dimensions of the component 4 are further arranged: the distance D between the center of the second through hole of the rotation preventing member 4 and the distal end portion 42 is larger than one-half of the diagonal length of the connecting plate 31, that is, it satisfies: l/2²+W/2²＝X²And D > X. This arrangement prevents the distal end portion 42 of the rotation-preventing member 4 from entering between the two side plates 32 at all, and thus can preferably function to prevent further rotation of the second locker 8.

It will be appreciated that when L/2 < D < X, the distal end portion 42 of the rotation preventing member 4 may rotate to between the two side plates 32 and come into contact with and interfere with the inner side surfaces of the side plates 32 at a position to stop the rotation.

In other embodiments, which are not shown, the anti-rotation part can also be designed in other shapes. For example, it is possible to design the rotation preventing member in a long strip shape longer than that of the present embodiment, and to locate the second through hole at the center thereof and to design the length thereof to be longer than the length of the diagonal line of the connecting plate. Thus, both ends of the rotation preventing member can interfere with both side plates simultaneously when the first locking member is tightened.

In another embodiment, not shown, it is also possible to provide the rotation prevention member as a cross shape composed of two elongated plates, with the second through-hole being positioned at the center of the cross shape. The length of these two rectangular plates all is greater than the diagonal length of connecting plate to when screwing up first retaining member, four tip that prevent changeing the part can take place to interfere with the curb plate simultaneously.

Preferably, in actual production and manufacture, a gasket 6, a shock absorber and the like are also arranged at the joint of the mounting assembly and the target equipment mounting frame 2. Specifically, a spacer 6 is provided between the nut of the first retaining member 7 and the target apparatus mounting bracket 2, a first damper 51 is provided between the spacer 6 and the target apparatus mounting bracket 2, and a second damper 52 is provided between the target apparatus mounting bracket 2 and the connecting plate 31, and through holes are provided in the above respective members, so that the first retaining member 7 can sequentially penetrate through the spacer 6, the first damper 51, between the target apparatus 1, the second damper 52 and the connecting plate 31, and be screw-fitted with the second retaining member 8 fixed in the rotation preventing member 4.
