Technical Field

[0001] The utility model relates to the technical field of engine bench tests, in particular to a detachable gantry bracket tooling. Background Art

[0002] Engine bench tests are an essential part of the research and development, production, and performance verification of automotive engines. During bench tests, the engine needs to be firmly installed on the bench, and usually, a gantry bracket is used to fix and install the engine. However, the existing engine gantry bracket tooling has an integrated gantry bracket formed, which can only limit the rear flange of a single-size engine and cannot meet the installation requirements for different engine rear flange sizes. If the outer diameter of the flange at the rear end of the engine is larger than the diameter of the gantry bracket tooling, the flange cannot be sleeved inside the gantry bracket tooling. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a detachable gantry bracket tooling to solve the technical problem that the existing gantry bracket cannot meet the installation requirements for different engine rear flange sizes in the prior art.

[0004] To achieve the above object, the utility model provides the following technical solution: A detachable gantry bracket tooling, including a fixed support and a sheet gantry. The sheet gantry includes a buckle part, and each end of the buckle part is provided with a connecting part. An arc-shaped component is rotatably connected to one end of the connecting part close to the buckle part, and the buckle part is a minor arc structure.

[0005] Preferably, when the arc-shaped component is in a closed state, the center of the arc of the arc-shaped component coincides with the center of the minor arc of the buckle part.

[0006] Preferably, the arc-shaped component and the connecting part are connected by a hinge shaft.

[0007] Preferably, a plurality of bolt holes are formed in both the buckle part and the arc-shaped component.

[0008] Preferably, the connecting part is detachably connected to the side plate of the fixed support by bolts.

[0009] Preferably, the buckle part and the connecting part are integrally formed.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] (1) The utility model provides a detachable gantry bracket tooling, which can not only limit the rear flange of the engine but also rotate the arc-shaped component to open a diameter suitable for the outer diameter of the rear flange of the engine, so as to sleeve the flange inside the gantry bracket tooling to meet the installation requirements for different flange sizes.

[0012] (2) The present utility model provides a detachable gantry bracket tooling. The sheet gantry is detachably connected to the fixed plate. If the sheet gantry or the fixed support is damaged, only the faulty component needs to be replaced, rather than the entire tooling, which provides convenience for the replacement and repair of the gantry bracket tooling.

[0017] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of this application.

[0018] As Figures 1-3 shown, a detachable gantry bracket tooling includes a fixed support 1 and a sheet gantry 2. The sheet gantry 2 includes a buckle part 21. At both ends of the buckle part 21, there is a connecting part 22 each. An arc-shaped component 3 is rotatably connected to one end of the connecting part 22 close to the buckle part 21. The buckle part 21 is a minor arc structure. The two arc-shaped components 3 can be rotated to be in an open state (please refer to Figure 2 ) or a closed state (please refer to Figure 1 ). When the arc-shaped component 3 is in the closed state, the center of the arc of the arc-shaped component 3 coincides with the center of the minor arc of the buckle part 21. This detachable gantry bracket tooling can not only limit the position of the flange at the rear end of the engine, but also rotate the arc-shaped component 3 to open a diameter suitable for the outer diameter of the flange at the rear end of the engine, so that the flange can be sleeved inside the gantry bracket tooling, and can meet the installation requirements of different flange sizes.

[0019] Specifically, please refer to Figure 1 , the arc-shaped component 3 is connected to the connecting part 22 through a hinge shaft 4. The arc-shaped component 3 and the connecting part 22 can also be rotatably connected through other components such as bolts.

[0020] Specifically, please refer to Figure 1 , the buckle part 21 and the connecting part 22 are integrally formed. A number of bolt holes are provided on the buckle part 21 and the two arc-shaped components 3 for connecting to the housing (not shown in the figure) at the rear end of the engine, and at the same time, the arc-shaped components 3 can be fixed. After adjusting the angle of the arc-shaped component 3 according to the outer diameter of the flange at the rear end of the engine, the arc-shaped component 3 is fixedly installed on the housing at the rear end of the engine in the adjusted state. Without separately providing a buckle component for the arc-shaped component 3, the buckle part 21 can provide fixed support for the flange at the rear end of the engine, and the arc-shaped component 3 maintains the adjusted angle to play a tightening role on the flange at the rear end of the engine.

[0021] As a further improvement, please refer to Figure 1 , the connecting part 22 of the plate-type gantry 2 is detachably connected to the side plate of the fixed support 1 by bolts. If the plate-type gantry 2 or the fixed support 1 is damaged, only the faulty component needs to be replaced, rather than the entire tooling, which can facilitate the replacement and maintenance of the gantry support tooling.

[0022] Specific implementation process: During use, the fixed support 1 is fixed on the iron floor by bolts. By rotating the two arc-shaped components 3 to open to a diameter suitable for the flange at the rear end of the engine, then the flange at the rear end of the engine is sleeved inside the gantry support tooling. The bolt holes on the buckle part 21 and the two arc-shaped components 3 are aligned with the bolt holes of the housing at the rear end of the engine, and the housing at the rear end of the engine is fixed on the gantry support tooling by bolts. Then, the flange at the rear end of the engine is connected to the transmission flange of the test bench to conduct the test bench test of the engine.

[0023] It should be noted that in the description of the present invention, relational terms such as "first", "second", etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions.
