Technical Field
[0001] The utility model relates to the technical field of fuel injection pump assemblies, in particular to an installation component for a fuel injection pump assembly. Background Technique
[0002] With the recovery of the global economy and the continuous development of the automotive industry, the market scale of fuel injection pump assemblies has maintained stable growth. Especially in emerging markets and developing countries, with the increase in the number of automobiles, the demand for fuel injection pump assemblies is also increasing continuously. Fuel injection pump assemblies are widely used in various mechanical equipment such as automobiles, generators, refrigeration equipment, and construction machinery. They are the core components of the fuel system in these equipment. They are responsible for injecting fuel into the combustion chamber at high pressure so that the engine can work normally.
[0003] A fuel injection pump assembly is an integral unit composed of components such as a fuel injection pump, a governor, a fuel transfer pump, and a return oil pipeline. It is responsible for pumping fuel out of the fuel tank and delivering it to the fuel injector, and adjusting the fuel injection volume and time according to the working conditions of the engine to achieve the best combustion effect and efficiency. Finally, part of the unburned fuel is recovered through the return oil pipeline to reduce emission pollution. It controls the fuel injection volume and injection time and has an important impact on the performance and emissions of the engine. In addition to these important components, the installation components between them are also important and are the cornerstone for these components to operate normally. For example, the high-pressure oil pipe between the fuel injection pump and the fuel transfer pipe needs to be fixed with a fixing bracket. However, the existing fixing brackets generally use metal frames to simply fix the oil pipe. For the inherent vibrations of some fuel engines, they cannot eliminate the vibrations of the high-pressure oil pipe, which will cause the high-pressure oil pipe to have rigid contact and collision damage with the inner wall under relatively high-amplitude vibrations, resulting in serious consequences such as oil leakage and the fuel engine being unable to work normally. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides an installation component for a fuel injection pump assembly, which solves the problem that the existing fixing brackets generally use metal frames to simply fix the oil pipe. For the inherent vibrations of some fuel engines, they cannot eliminate the vibrations of the high-pressure oil pipe, which will cause the high-pressure oil pipe to be damaged under relatively high-amplitude vibrations, resulting in serious consequences such as oil leakage and the fuel engine being unable to work normally.
[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: An installation component for a fuel injection pump assembly includes an installation and fixing component.

One end of the spring is fixedly connected to the outer wall of the fixing arc plate, and the other end of the spring is fixedly connected to the inner wall of the box body. The fixing arc plate is arranged inside the circular hoop member.
[0006] Preferably, the installation and fixing assembly further includes an oil pipe elbow joint and a ferrule type pipe joint. The oil pipe elbow joint is arranged at one end of the anti-vibration fixing bracket, and the ferrule type pipe joint is arranged at the other end of the anti-vibration fixing bracket.
[0007] Preferably, a connecting piece is fixedly connected to the box body.
[0008] Preferably, protective soft sleeves are sleeved at both ends of the box body.
[0009] Preferably, the number of the springs and the fixed arc plates is four groups each, and the four groups of springs and fixed arc plates are distributed in an annular array on the inner wall of the box body.
[0010] Preferably, a rubber soft pad is fixedly connected to the inner wall of the fixed arc plate.
[0011] Preferably, the circular hoop member includes a left hoop, a right hoop and a fixing bolt. The left hoop and the right hoop are fixedly connected to the outer wall of the fixed arc plate through the fixing bolt.
[0012] The utility model discloses an installation assembly for a fuel injection pump assembly, and the beneficial effects thereof are as follows: By arranging an inner bracket and an outer box frame in the installation and fixing assembly, and arranging four groups of springs between the two, when vibration is transmitted to the bracket, it will first pass through the vibration damping of the springs, and finally a small amount of vibration is transmitted to the oil pipe in the inner bracket, avoiding damage to the high-pressure oil pipe caused by rigid contact and collision between the high-pressure oil pipe and the fixing part during vibration.

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0022] By providing an installation component for a fuel injection pump assembly in the embodiments of the present application, the problem that existing fixing brackets generally use metal frames to simply fix oil pipes is solved. For the inherent vibrations of some fuel engines, the vibration elimination of high-pressure oil pipes cannot be carried out, which will cause the high-pressure oil pipes to be damaged under relatively high-amplitude vibrations, resulting in serious consequences such as oil leakage and the inability of the fuel engine to work properly.
[0023] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.
[0024] The embodiments of the present utility model disclose an installation component for a fuel injection pump assembly.
[0025] According to the appendix Figure 1-6As shown in the figure, it includes an installation and fixing component 1. The installation and fixing component 1 is provided with a vibration-proof fixing bracket 11. The vibration-proof fixing bracket 11 includes an outer box frame 111 and an inner bracket 112. The inner bracket 112 is arranged inside the outer box frame 111. The outer box frame 111 is provided with a box body 1111. The inner bracket 112 includes a fixed arc plate 1121, a spring 1122 and a circular hoop member 1123. One end of the spring 1122 is fixedly connected to the outer wall of the fixed arc plate 1121, and the other end of the spring 1122 is fixedly connected to the inner wall of the box body 1111. The fixed arc plate 1121 is arranged inside the circular hoop member 1123. By changing the fixed bracket into a vibration-proof fixing bracket 11 with a separable outer box frame 111 and inner bracket 112, and connecting them to each other through the spring 1122, the vibration damping effect of the installation and fixing component 1 is greatly improved. Through the four fixed arc plates 1121 and the circular hoop member 1123, high-pressure oil pipes of different models can be effectively and firmly installed inside the inner bracket 112, and the loading, unloading and replacement are convenient.
[0026] The installation and fixing component 1 further includes an oil pipe elbow joint 12 and a ferrule type pipe joint 13. The oil pipe elbow joint 12 is arranged at one end of the vibration-proof fixing bracket 11, and the ferrule type pipe joint 13 is arranged at the other end of the vibration-proof fixing bracket 11. One end of the oil pipe elbow joint 12 is connected to the high-pressure oil pipe, and the other end can be threadedly connected to the fuel injection pump. One end of the ferrule type pipe joint 13 is connected to the high-pressure oil pipe, and the other end is movably inserted into the fuel transfer pump, and together with the vibration-proof fixing bracket 11, it constitutes the whole set of installation and fixing component 1.
[0027] A connecting piece 1112 is fixedly connected to the box body 1111. The vibration-proof fixing bracket 11 is fixedly connected to the inner wall of other equipment, such as a fuel engine, through the connecting piece 1112.
[0028] Protective soft sleeves 1113 are sleeved on both ends of the box body 1111. The protective soft sleeves 1113 sleeved on the box body 1111 provide dust protection for the vibration-proof fixing bracket 11 and vibration damping protection for the connection parts of the vibration-proof fixing bracket 11 with the oil pipe elbow joint 12 and the ferrule type pipe joint 13.
[0029] The number of the springs 1122 and the fixed arc plates 1121 is four groups each, and the four groups of springs 1122 and fixed arc plates 1121 are annularly arrayed on the inner wall of the box body 1111. There are four groups of springs 1122 and fixed arc plates 1121 arranged in corresponding annular arrays, providing elastic support for the high-pressure oil pipe to avoid damage to the high-pressure oil pipe caused by rigid contact and collision between the high-pressure oil pipe and the fixing parts during vibration.
[0030] A rubber soft pad 1124 is fixedly connected to the inner wall of the fixed arc plate 1121. The vibration damping and anti-collision characteristics of the rubber soft pad 1124 itself make the vibration damping effect of the installation component for the fuel injection pump assembly better, providing protection and anti-collision effect for the high-pressure oil pipe.
[0031] The circular hoop member 1123 includes a left hoop 11231, a right hoop 11232 and a fixing bolt 11233. The left hoop 11231 and the right hoop 11232 are fixedly connected to the outer wall of the fixed arc plate 1121 through the fixing bolt 11233. The four groups of fixed arc plates 1121 are abutted against the left hoop 11231 and the right hoop 11232, and are threadedly connected through the fixing bolt 11233 to firmly press the high-pressure oil pipe within the four groups of fixed arc plates 1121.
