Description

Technical Field

[0001] The invention relates to the technical field of diesel engines, in particular to an auxiliary tool for diesel engine oil hole pump water sealing test. Background Art

[0002] Medium-speed diesel engine is a kind of diesel engine. Under the same power, it is smaller and lighter than low-speed diesel engine. However, due to the high speed, medium-speed engine will increase wear. Due to the large number of cylinders, the failure rate of parts is also increased accordingly. Therefore, the requirements for its quality, precision and performance are higher than those of ordinary marine low-speed diesel engines. Diesel engine is the heart of the ship, and its importance is self-evident. Therefore, in the processing of all its parts, each process is strictly carried out in accordance with the requirements of the process and drawings. After one process is completed, it must be strictly inspected by professional inspectors. Only when it meets the requirements can the next process be carried out. For each finished part, we must strive for excellence. The pump water test is an indispensable and important process in the processing process. It can test the internal sealing of the entire part during the casting process. Since the frame oil circuit is usually in the middle of the frame main bearing seat, there is an oil groove on the top of the oil hole. The original rubber extrusion sealing tool alone will cause the sealing tool to be unstable during the sealing test, and the sealing tool will be separated from the sealing oil hole, affecting the stability of the sealing test.

[0003] Therefore, it is necessary to provide a new auxiliary tool for diesel engine oil hole pump water seal test to solve the above technical problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an auxiliary tool for diesel engine oil hole pump water sealing test.

[0005] The auxiliary tool for diesel engine oil hole water pump sealing test provided by the present invention comprises: a water pump pipeline, a fixed block, a sealing oil hole, an adjusting block, an assembly groove and an elliptical hole. The fixed block is arranged below the water pump pipeline, the sealing oil hole is opened inside the water pump pipeline, the adjusting blocks are symmetrically arranged on the side of the fixed block, the assembly groove is symmetrically opened inside the fixed block, and the elliptical hole is opened on the surface of the adjusting block. The fixed block is placed close to the water pump pipeline to seal the sealing oil hole, and the adjusting block is fixedly installed on the side of the fixed block through the assembly groove and the elliptical hole. The adjusting block contacts the surface of the water pump pipeline, and the water pump pipeline and the fixed block are quickly assembled.

[0006] Preferably, the inner wall of the assembly groove is meshed with a clamping screw, and the clamping screw is connected to the elliptical hole, and the clamping screw is fixedly connected to the side of the clamping screw away from the adjusting block. The adjusting block is brought close to the fixed block, the clamping screw passes through the elliptical hole, the surface of the clamping screw contacts the inner wall of the assembly groove, and the clamping block is tightly attached to the surface of the adjusting block, so that the fixed block and the adjusting block are quickly assembled.

[0007] Preferably, a screw thimble is inserted into the fixing block, a rubber sealing ring and a limiting ring are sleeved on the surface of the screw thimble, and the rubber sealing ring is located above the limiting ring, a nut is meshingly connected on the surface of the screw thimble, and the nut is located below the limiting ring, the screw thimble passes through the fixing block from above, the nut is rotated, the inner wall of the nut contacts the surface of the screw thimble, the nut moves upward, the nut squeezes the limiting ring to move upward, the limiting ring squeezes the rubber sealing ring, the rubber sealing ring is squeezed and deformed, and becomes larger in the circumferential direction, thereby sealing the sealing oil hole.

[0008] Preferably, the nut adopts an equilateral hexagonal design, which is convenient for manually driving the nut to rotate. Compared with a circular design, it is convenient to quickly drive the nut to rotate, thereby improving the practicality of the nut.

[0009] Preferably, the bottom of the water pumping pipe adopts a truncated cone design, and the surface of the adjusting block adopts a sloped design. After the adjusting block and the fixed block are assembled, the sloped surface of the adjusting block contacts the truncated cone surface of the water pumping pipe, and the water pumping pipe and the fixed block are quickly connected to ensure that the water pumping pipe and the fixed block will not be easily separated when connected.

[0010] Preferably, the fixing block is made of stainless steel material, which has high physical strength and excellent corrosion resistance. When the sealing oil hole is sealed, oil and water will not easily corrode the fixing block, ensuring that the fixing block will not be easily damaged after long-term use, thereby extending the service life of the fixing block.

[0011] Preferably, the top edge of the screw pin is rounded to reduce the friction at the edge of the screw pin. When the fixing block is close to the water pump pipe and the screw pin enters the sealing oil hole, the edge of the screw pin will contact the inner wall of the sealing oil hole, reducing the wear on the sealing oil hole.
