Description

Technical Field

[0001] This utility model belongs to the field of automotive engine testing technology, specifically relating to an automotive engine assembly testing device. Background Technology

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The term "engine" can refer to both the power generating device and the entire machine including the power generating device (e.g., gasoline engine, aircraft engine). Engines originated in Britain, so the concept of engine also comes from English, and its original meaning refers to a "mechanical device that generates power".

[0003] Problems with existing technology:

[0004] Currently, when using automotive engine assembly testing equipment, it is usually necessary to test the combustion of the engine, which requires testing its exhaust content. However, when using existing testing equipment, the high temperature of the exhaust gas can easily damage the testing equipment. In addition, since engine models are usually different, the existing equipment does not have a flexible adjustment structure. Utility Model Content

[0005] The purpose of this invention is to provide an automotive engine assembly testing device that can solve the problems of high-temperature exhaust gases from the engine easily damaging the testing device during use, and the inability to flexibly adjust the testing device for different engine models.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An automotive engine assembly and testing device includes a frame, with a hydraulic rod mounted on the top of the frame for driving the housing to move vertically.

[0008] The housing is equipped with a moving mechanism, which is used to drive the adjustment mechanism to move the acquisition mechanism horizontally.

[0009] The collection mechanism includes a cooling bottle and a cooling pipe. A sealing cap is fixedly installed on the top of the cooling bottle. A collection port and an air supply port are respectively provided on both sides of the sealing cap. A cooling pipe is fixedly connected to the bottom of the sealing cap.

[0010] A conveyor is installed at the back of the frame, and a first detector and a second detector are arranged vertically inside one side of the frame.

[0011] The air supply port is used for the fixed installation of the sealing cover and the adjustment mechanism. The air supply port is fixedly connected to one end of the cooling pipe, and the other end of the cooling pipe is fixedly connected to the collection port.

[0012] The moving mechanism includes a first motor and a mounting bracket. The first motor is used to drive the lead screw to rotate, and the mounting bracket is threaded onto the surface of the lead screw.

[0013] The first motor is fixedly installed on one side of the housing, the lead screw is rotatably installed inside the housing, and an adjustment mechanism is fixedly connected to the bottom of the mounting bracket.

[0014] The adjustment mechanism includes a first mounting plate, a second motor, and a rack. A temporary storage tube is fixedly connected to the bottom of the first mounting plate, and the second motor is used to drive the gear to move along the top of the rack.

[0015] The first mounting plate and the second mounting plate are hinged together, and the temporary storage tube is a telescopic structure. The temporary storage tube is fixedly connected to the first detector through a telescopic tee tube.

[0016] A gear is rotatably mounted on the top interior of the first mounting plate. The gear meshes with a rack, which is arc-shaped.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This invention utilizes a lead screw installed inside the housing, which is driven by a first motor to rotate. This allows the mounting frame to drive the collection mechanism to move horizontally via an adjustment mechanism. Since the cooling bottle and sealing cap of the collection mechanism are fixedly installed, and the sealing cap is fixedly connected to the adjustment mechanism via an air supply port, and a collection port is installed on the other side of the sealing cap, the collection port can be connected to the engine's exhaust port when the collection mechanism moves. This allows the gas emitted from engine combustion to enter the cooling pipe through the collection port. Because the cooling bottle is filled with cooling water, the gas is cooled before being sent to the adjustment mechanism, and then through a telescopic three-way pipe to the interior of the first and second detectors. These two instruments respectively detect carbon monoxide and carbon dioxide content, thus enabling the detection of whether combustion is complete after engine assembly.

[0019] This utility model features an adjustment mechanism installed between a moving mechanism and a collecting mechanism. The first mounting plate of the adjustment mechanism is hinged to a second mounting plate via a hinge. A rack is fixedly installed on the top of the second mounting plate, while a second motor and a gear are respectively installed on the top of the first mounting plate. Through the cooperation of the two, the gear can move along the top of the rack, thereby driving the first mounting plate and the collecting mechanism to adjust their angles. This makes it suitable for use with different engine models. Attached Figure Description

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figure 1-5 As shown, an automotive engine assembly and testing device includes a frame 1, with a hydraulic rod 5 mounted on the top of the frame 1. The hydraulic rod 5 is used to drive the housing 6 to move vertically.

[0029] The housing 6 is equipped with a moving mechanism 7, which drives the adjustment mechanism 8 to move the acquisition mechanism 9 horizontally.

[0030] The collection mechanism 9 includes a cooling bottle 91 and a cooling pipe 95. A sealing cap 92 is fixedly installed on the top of the cooling bottle 91. A collection port 93 and an air supply port 94 are respectively provided on both sides of the sealing cap 92. The cooling pipe 95 is fixedly connected to the bottom of the sealing cap 92.

[0031] See attached document Figure 1 and Figure 2In this embodiment, a conveyor 2 is provided on the back of the frame 1, and a first detector 3 and a second detector 4 are arranged vertically inside one side of the frame 1.

[0032] In the above embodiment, the assembled engine can be sent to the inside of the frame 1 by the action of the conveyor 2, so that it can be detected by the first detector 3 and the second detector 4 inside the frame 1.

[0033] In the above structure, the first detector 3 and the second detector 4 are connected to the acquisition mechanism 9 through the adjustment mechanism 8. The first detector 3 is a carbon monoxide detector, and the second detector 4 is a carbon dioxide detector. Through the action of the two, the combustion of the engine after assembly can be detected.

[0034] See attached document Figure 2 , Figure 3 and Figure 4 In this embodiment, the air supply port 94 is used to fix the sealing cover 92 and the adjustment mechanism 8. The air supply port 94 is fixedly connected to one end of the cooling pipe 95, and the other end of the cooling pipe 95 is fixedly connected to the collection port 93.

[0035] In the above embodiment, the gas discharged from the engine can be collected through the collection port 93 and then sent into the interior of the cooling pipe 95. Since the cooling pipe 95 is located inside the cooling bottle 91 and the interior of the cooling bottle 91 is filled with cooling water, the gas can be cooled.

[0036] Furthermore, the cooled gas can be sent into the interior of the air supply port 94 through one end of the cooling pipe 95, and the air supply port 94 is installed with the regulating mechanism 8, so the cooled gas can be sent into the interior of the first detector 3 and the second detector 4 through the regulating mechanism 8 and the telescopic three-way pipe 10 respectively.

[0037] See attached document Figure 1 and Figure 2 In this embodiment, the moving mechanism 7 includes a first motor 71 and a mounting bracket 73. The first motor 71 is used to drive the lead screw 72 to rotate, and the mounting bracket 73 is threaded onto the surface of the lead screw 72.

[0038] According to the above structure, since the first motor 71 is fixedly installed on one side of the housing 6, and the lead screw 72 is rotatably installed inside the housing 6, the first motor 71 can drive the lead screw 72 to rotate, thereby causing the mounting frame 73 to slide horizontally on the surface of the lead screw 72. The bottom of the mounting frame 73 is fixedly connected to the adjustment mechanism 8, so the adjustment mechanism 8 can drive the acquisition mechanism 9 to move horizontally.

[0039] See attached document Figure 2 and Figure 5In this embodiment, the adjustment mechanism 8 includes a first mounting plate 81, a second motor 84, and a rack 86. A temporary storage tube 83 is fixedly connected to the bottom of the first mounting plate 81, and the second motor 84 is used to drive the gear 85 to move along the top of the rack 86.

[0040] In the above embodiment, the first mounting plate 81 and the second mounting plate 82 can be connected together by the temporary storage tube 83, and the second motor 84 can drive the gear 85 to rotate on the top of the rack 86.

[0041] Specifically, a hinge is hinged between the first mounting plate 81 and the second mounting plate 82 to allow them to move and connect. At the same time, the temporary storage tube 83 is a telescopic structure, so when the first mounting plate 81 moves, the temporary storage tube 83 can extend and retract synchronously. The temporary storage tube 83 can store cooled gas, and the temporary storage tube 83 is fixedly connected to the first detector 3 through the telescopic tee tube 10, so that the gas can be sent into the equipment for detection.

[0042] More specifically, since gear 85 is rotatably installed inside the first mounting plate 81 and meshes with rack 86, which is arc-shaped, when gear 85 rotates, it can move along the surface of rack 86, thereby driving the first mounting plate 81 to move synchronously, so that the acquisition mechanism 9 can be adjusted.

[0043] The working principle of this utility model is as follows: The engine is sent to the inside of the frame 1 by starting the conveyor 2. The housing 6 is moved down by the hydraulic rod 5, so that the collection port 93 moves to the same level as the engine exhaust port. Then, the first motor 71 is started, so that the lead screw 72 drives the collection mechanism 9 to move towards the engine exhaust port through the mounting bracket 73 and the adjustment mechanism 8. The second motor 84 is started, so that the gear 85 rotates. Since the gear 85 meshes with the rack 86, the first mounting plate 81 drives the collection mechanism 9 to adjust the angle, so that the collection port 93 is connected to the exhaust port, thereby collecting the gas discharged from the engine. The collected gas enters the interior of the cooling pipe 95 through the collection port 93 and is cooled by the cooling water inside the cooling bottle 91. The cooled gas enters the temporary storage pipe 83 through the gas supply port 94. The temporary storage pipe 83 is connected to the first detector 3 and the second detector 4 by a telescopic three-way pipe 10, so that the gas enters the first detector 3 and the second detector 4 respectively for carbon monoxide and carbon dioxide detection, thereby realizing the detection of whether the combustion is complete after the engine is assembled.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
