Description

Technical Field

[0001] The utility model relates to the technical field of engine assembly, in particular to an engine left bracket reinforcement plate assembly structure. Background Art

[0002] An engine is an energy conversion device that can convert chemical energy, thermal energy, electrical energy, etc. into mechanical energy. Depending on the energy conversion method, engines can be divided into internal combustion engines, external combustion engines, jet engines, and electric motors.

[0003] The left engine bracket is an important component used to fix the engine to the wing or frame in vehicles such as airplanes or cars. Its main function is to withstand the load generated by the engine during flight or driving by cooperating with the middle and rear casings of the aircraft and then connecting them with the tie rods for strength. Therefore, the quality of the left engine bracket directly affects the safety of flight or driving. In an airplane, the engine bracket must not only bear the weight of the engine, but also various dynamic loads during flight, such as load changes during takeoff, landing, turning, etc. Therefore, the design, manufacture and installation of the engine bracket need to be strictly calculated and tested to ensure its strength and reliability.

[0004] The engine left bracket reinforcement plate is an auxiliary component used to enhance the strength and rigidity of the engine left bracket. It is usually connected to the engine left bracket by welding, bolting or other means to form an integral structure. The functions of the reinforcement plate are mainly as follows:

[0005] Increased strength and rigidity: The reinforcement plate can effectively increase the strength and rigidity of the left engine bracket, enabling it to withstand greater loads and vibrations, and improve the stability and safety of the engine.

[0006] Optimize stress distribution: By rationally designing the shape and size of the reinforcement plate, the stress distribution of the left engine bracket can be optimized, reducing the risk of stress concentration and fatigue failure.

[0007] Improved durability: The reinforcement plate is usually made of high-strength, corrosion-resistant materials, which can effectively improve the durability and service life of the left engine bracket. When designing and manufacturing the left engine bracket reinforcement plate, many factors need to be considered, such as the material's strength, rigidity, corrosion resistance, processing performance, etc., as well as the connection method and installation position of the reinforcement plate and the left engine bracket. At the same time, strict testing and verification are also required to ensure that the reinforcement plate can effectively improve the performance and reliability of the left engine bracket.

[0008] The assembly process of the engine left bracket reinforcement plate in the prior art mainly involves the connection with the engine left bracket. The engine left bracket reinforcement plate is provided with a bolt assembly hole connected to the left bracket. The bolt assembly hole is designed as an elliptical hole. Such a design helps to eliminate the problem of poor product assembly due to the error between products, and also ensures the product assembly quality and improves the assembly work efficiency. The left bracket reinforcement plate is fixed to the left bracket by passing the bolt through the elliptical hole on the left bracket reinforcement plate and connecting it with the corresponding hole on the left bracket.

[0009] The above installation method has a great defect. It only connects the engine left bracket reinforcement plate and the engine left bracket by passing bolts through the bolt assembly holes. However, in actual installation, there are many holes for assembly, which makes it troublesome to align the bolt assembly holes one by one during the assembly process, thereby reducing the installation efficiency of the engine left bracket reinforcement plate and the engine left bracket. Utility Model Content

[0010] The utility model aims to provide an engine left bracket reinforcement plate assembly structure to solve the problems raised in the above background technology.

[0011] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] As a preferred solution of the utility model, a plurality of fixing screw holes for assembly located on the left bracket and the reinforcing plate are opened one by one corresponding to each other, and are fixedly connected by bolts.

[0014] As a preferred solution of the utility model, the multiple positioning posts on the left bracket and the multiple positioning holes on the reinforcing plate cooperate with each other one by one, and the positioning posts and the positioning holes are internally plugged into each other.

[0015] As a preferred solution of the utility model, two elastic blocks are fixedly provided on both sides of the outer wall of the buckle, two contacts are opened on both sides of the inner wall of the slot, and the elastic blocks are snapped into the two contacts through elastic design.

[0016] As a preferred solution of the utility model, the overall size of the buckle is smaller than the internal size of the slot, so that the buckle is entirely inserted into the interior of the slot.

[0017] As a preferred solution of the utility model, the plurality of positioning posts and the left bracket are integrally formed.

[0018] As a preferred solution of the present invention, the left bracket and the reinforcement plate are both made of aluminum alloy.

[0019] Beneficial effect: In the prior art, the connection between the left engine bracket reinforcement plate and the left engine bracket is only performed by passing bolts through the bolt assembly holes. However, in actual installation, there are many holes for assembly, which makes it troublesome to align the bolt assembly holes one by one during the assembly process, thereby reducing the installation efficiency of the left engine bracket reinforcement plate and the left engine bracket. In the utility model, a positioning column for positioning and a screw hole for assembly are provided on the original left bracket, and a positioning hole for positioning and a screw hole for assembly are provided at a corresponding position on the original reinforcement plate, and then positioning and fixing are performed between the positioning column and the positioning hole, so as to facilitate the subsequent installation of the left engine bracket reinforcement plate and the left engine bracket by passing bolts through the bolt assembly holes. At the same time, a buckle is provided on the original reinforcement plate, and a slot is provided on the original left bracket. Two elastic blocks are fixedly provided on both sides of the outer wall of the buckle, and two contacts are provided on both sides of the inner wall of the slot, and the elastic block is elastically designed to be inserted into the two contacts, thereby achieving the purpose of reinforcement, improving the installation efficiency and stability of the left engine bracket reinforcement plate and the left engine bracket, which is very practical.
