Description
Technical Field
The invention relates to an engine thrust plate misloading and neglected loading prevention guide tool in the technical field of automobile engines.
Background
At present, a thrust plate is arranged between the shaft seat end surface and the crankshaft end surface of an engine cylinder body and is used for axially positioning a crankshaft, preventing the crankshaft from axially moving and ensuring the stable operation of the crankshaft, a connecting rod and a bearing bush of the engine. If the thrust plate is neglected to be installed, the axial displacement of the crankshaft is too large, the crankshaft is unstable in operation, serious faults of a connecting rod cylinder pulling can also cause the oil pump chain and the timing chain to fall off, serious consequences such as incapability of supplying engine oil and wrong timing can be caused, the faults can directly cause the scrapping of an engine, and therefore the neglected installation of the thrust plate is strictly not allowed.
The front and back surfaces of the thrust plate are required to be installed, one side of the thrust plate is in contact with the end surface of the cylinder block shaft seat, the other side of the thrust plate is in contact with the crankshaft, the thrust plate and the cylinder block are relatively static, and generally, the surface of the thrust plate, which is in contact with the cylinder block shaft seat, is made of relatively hard material. The crankshaft rotates at a high speed, the thrust plate and the crankshaft are always in a relative sliding friction state, so that the surface of the thrust plate, which is in contact with the crankshaft, needs good lubrication, an oil groove is formed in the surface of the thrust plate, which is in contact with the crankshaft, and the surface of the thrust plate, which is in contact with the crankshaft, is made of wear-resistant and anti-friction materials. If the thrust piece dress is reversed, can cause not having the great one side of oil groove and hardness and the contact of bent axle, and the relatively softer one side of material and cylinder block axle bed contact, this can cause the one side of thrust piece and bent axle contact because there is not the oil groove to obtain good lubrication, the wearing and tearing of thrust piece and bent axle accelerate, after bent axle and thrust piece attenuation because of wearing and tearing, the clearance that the thrust piece will follow between bent axle and the cylinder block axle bed drops, lead to bent axle axial float, and then the connecting rod draws the jar, the oil pump chain, timing chain drops, finally cause the engine to directly scrap. Therefore, reverse installation of the thrust plate is absolutely not allowed. Many assembly lines rely on manual judgement to prevent neglected loading and wrong loading of thrust plate, and it is obviously not a reliable fool-proofing measure to rely on human judgement to prevent mistake.
Chinese patent document (published: 2/19/2014, publication number: CN 203437885U) discloses an engine crankshaft thrust piece mistake-proofing tool, which comprises a tool main body and a sensor, wherein the tool main body is provided with a working surface, the working surface is provided with a guide device, one side of the guide device, which is opposite to the working surface, is provided with a guide groove, which is vertical to a horizontal plane and corresponds to a crankshaft thrust piece mounting hole, the guide groove is internally provided with a mistake-proofing structure matched with an oil groove in a thrust piece, and the sensor is arranged on the guide device and is connected with a station control system, and is vertical to the working surface of the tool main body. The guide tool can realize the misloading prevention and the neglected loading of the thrust plate by utilizing the misloading prevention structure and the sensor.
According to the technical scheme, whether the thrust plate is neglected to be installed or not is judged through the sensor, and the thrust plate is required to be connected with a station control system and cannot be installed by only one tool. In addition, in the above technical solution, it is mentioned that, after the thrust plate is inserted into the tool, the thrust plate may fall into the thrust plate groove between the crankshaft thrust surface and the cylinder block thrust surface by its own gravity, but actually, when the thrust plate is not installed, the crankshaft may move in the axial direction, and the width of the thrust plate groove may be large or small, so that it is not practical to install the thrust plate at a predetermined position by simply relying on the own gravity of the thrust plate. Therefore, although the tool can realize error-proof and neglected installation, the thrust plate cannot be directly installed in place by the tool. Therefore, the development of a guide tool for preventing the misloading and the neglected loading of the thrust plate of the engine is a new problem to be solved urgently.
