Description

Technical Field

[0001] This utility model relates to the field of automotive oil pump testing, and specifically refers to a sealing tooling assembly for automotive oil pump testing. Background Technology

[0002] The oil pump in the lubrication system pressurizes the engine oil to a certain level and forces it onto the moving surfaces of various engine parts for cooling and lubrication. Therefore, the oil pump plays a crucial role in the operation of an internal combustion engine. Oil leakage in the pump chamber can have irreparable consequences for the engine's operation and even the safety of the driver and passengers. Therefore, a rigorous sealing test of the oil pump chamber must be conducted before assembling the internal combustion engine.

[0003] Existing sealing test equipment for sealing the unit of the fixed oil pump requires multiple cylinders to drive it, which is not only complex in structure but also expensive. For example, prior art 201810196976.9 discloses a device for testing the sealing performance of an automotive oil pump chamber. Utility Model Content

Two connecting plates 56 are hinged at one end of plate 54 away from connecting rod cylinder 52 and at the other end respectively hinged to both ends of the second drive plate 55; the bottom of the two connecting plates 56 are rotatably connected to the fixed plate 1 through rotating shaft 57; the telescopic ends of the two sets of sealing components 3 respectively pass through the detection water tank 2 and the two mounting plates 51 and are connected to the first drive plate 53 and the second drive plate 55; the sealing component 4 includes a telescopic tube 41 inclinedly arranged on one side of the detection water tank 2, a telescopic sealing rod 42 telescopically arranged in the telescopic tube 41, a limiting plate 43 arranged on the section of the telescopic sealing rod 42 located in the telescopic tube 41, and a limiting plate 43 sleeved on the section of the telescopic sealing rod 42 located in the telescopic tube 41. A spring 44 on a section of the telescopic tube 41 is used to push the limiting plate 43 to disengage the telescopic sealing rod 42 from the oil pump outlet. An inclined block 45 is correspondingly set on the telescopic plate 54 on one side of the telescopic sealing rod 42 to push one end of the telescopic sealing rod 42 toward the telescopic tube 41. The two sets of sealing assemblies 3 include two sealing plates 31 set in the detection water tank 2 at both ends of the oil pump, and four telescopic rods 32 with one end fixedly connected to the two sides of the two sealing plates 31 facing the detection water tank 2 and the other end passing through both ends of the detection water tank 2 and the two mounting plates 51 fixedly connected to the first drive plate 53 and the second drive plate 55.

[0019] Furthermore, a pulley 7 is provided on the end of the telescopic sealing rod 42 that is in contact with the inclined block 45, making the sliding more stable.

[0020] In use: When it is necessary to seal the oil pump in the test tank 2, firstly, start the connecting rod cylinder 52. The output end of the connecting rod cylinder 52 drives the first drive plate 53 towards one end of the mounting plate 51. The first drive plate 53 simultaneously drives the two telescopic plates 54 to move towards the other end and drives the two telescopic rods 32 at the same end to move towards the test tank 2. At the same time, the two telescopic plates 54 push one end of the connecting plate 56 to move away from the mounting plate 51. Since the bottom of the two connecting plates 56 is rotatably connected to the fixed plate 1, the other end of the connecting plate 56 moves towards the mounting plate 51. Then, the end of the connecting plate 56 that is hinged to the second drive plate 55 drives the second drive plate 55 to move towards the mounting plate 51. The second drive plate 55 drives the two telescopic rods 32 at the same end to move towards the test tank 2. Then, the four telescopic rods 32... Do not push the two sealing plates 31 to move towards both ends of the oil pump and seal both ends of the oil pump. At the same time, the telescopic plate 54 located on one side of the telescopic tube 41 moves and drives the tilting block 45 to move towards one end of the telescopic sealing rod 42. As the tilting surface of the tilting block 45 gradually approaches the side of the detection water tank 2, the tilting block 45 moves and pushes the telescopic sealing rod 42 towards one end of the telescopic tube 41. Then, the end of the telescopic sealing rod 42 located in the detection water tank 2 moves towards the oil outlet of the oil pump and blocks the oil outlet of the oil pump. Then the oil pump is sealed. During the fixing process, the position of the oil pump can be finely adjusted by the fine-adjustment component 6. Since the fine-adjustment component 6 is prior art with patent number 201810196976.9, patent name is a device for detecting the sealing performance of an automotive oil pump chamber, the structure will not be described in detail.

[0021] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
