Description

Technical Field

[0001] The utility model relates to the technical field of crankcases, in particular to a diesel engine crankcase. Background Art

[0002] When the crankcase cover is installed during production, a gasket is installed between the cover and the crankcase to improve the sealing. During the installation operation, the gasket is first placed on the outer surface of the crankcase to cover the position, and then the cover is placed on the gasket, and the cover is fixed to the crankcase with bolts. However, in actual operation, it is found that if the gasket is placed on the crankcase first and then the cover, the gasket is likely to move, causing the holes on the gasket to be misaligned with the holes on the cover. After multiple alignments, the cover can be stably installed on the crankcase, wasting time and reducing work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0026] Reference Figure 1-Figure 4 The utility model provides a technical solution: a diesel engine crankcase, including a body 1 and an anti-misalignment mechanism 3, and a top cover 2 is installed on the body 1, the anti-misalignment mechanism 3 includes a vertical rod 31, the vertical rod 31 is fixedly installed on one side of the body 1, a groove 311 is opened on the top of the vertical rod 31, a magnetic block 32 is rotatably installed inside the groove 311, a positioning hole 33 is opened on the outer surface of the top cover 2, and the magnetic block 32 passes through the inside of the positioning hole 33.

[0027] In a preferred embodiment, a plurality of bolts 4 are provided on the top cover 2 and are evenly arranged on the outer surface of the top cover 2. The bolts 4 are threadedly connected to the body 1 to fix the top cover 2 and the body 1 together. In order to fix the top cover 2 on the body 1, the device has a plurality of bolts 4 installed on the top cover 2. Each bolt 4 is screwed into the inside of the body 1 to achieve a stable connection between the top cover 2 and the body 1.

[0028] In a preferred embodiment, a sealing gasket 5 is installed between the body 1 and the top cover 2, a through hole 6 is opened on the upper surface of the sealing gasket 5, and the bolt 4 passes through the inside of the through hole 6. Since there is oil inside the crankcase, in order to prevent the oil from leaking, a sealing gasket 5 is installed between the body 1 and the top cover 2, and the sealing effect of the crankcase is improved by the sealing gasket 5.

[0029] In a preferred embodiment, the top cover 2 is made of metal, and an arc-shaped hole 7 is opened at one end of the top cover 2, which is combined with the hole on the body 1 to form an axial hole. In order to prevent the sealing gasket 5 from being misplaced, after the vertical rod 31 extends out of the interior of the top cover 2, the magnetic block 32 can be rotated to adsorb the magnetic block 32 and the top cover 2 together to limit the top cover 2. At the same time, the sealing gasket 5 can also be squeezed and limited to prevent the sealing gasket 5 from being misplaced.

[0030] During the use of the crankcase, metal impurities are inevitably generated. These metal impurities are constantly moving inside the crankcase, which can easily cause damage to the crankshaft. In order to extend the service life of the crankshaft, a debris absorption mechanism 8 is fixedly installed inside the top cover 2. The debris absorption mechanism 8 includes a limit rod 81, a sphere 82 and a magnetic plate 83. The limit rod 81 is fixedly installed on the inner wall of the top cover 2, and a connecting rod 9 is fixedly installed on one side of the limit rod 81. The sphere 82 is fixedly installed on one end of the connecting rod 9. There are four limit rods 81, which are evenly arranged on the inner wall of the top cover 2. A sphere 82 is installed at one end of each limit rod 81. A magnetic plate 83 is installed inside the top cover 2. The magnetic plate 83 is arranged on the inner side of the sphere 82, and the outer surface of the magnetic plate 83 is tightly fitted with the outer surface of the sphere 82.

[0031] In actual use, in order to prevent metal impurities from damaging the internal crankshaft, a magnetic plate 83 is installed inside the top cover 2. The oil constantly moves inside the crankcase and will enter the position of the magnetic plate 83. At the same time, the metal impurities in the oil will also move to the position of the magnetic plate 83. The magnetic plate 83 adsorbs the metal impurities to prevent the impurities from continuing to mix with the oil to damage the crankshaft, thereby ensuring that the crankcase can be used normally. When cleaning the interior of the crankcase at a later time, the metal impurities on the magnetic plate 83 can be cleaned off.

[0032] Specifically, a working process or working principle of a diesel engine crankcase is as follows: when the crankcase is produced and covered, a sealing gasket 5 is installed between the cover body and the crankcase to improve the sealing performance. During the installation operation, the sealing gasket 5 is first placed at the position of the cover on the outer surface of the crankcase, and then the cover body is covered on the sealing gasket 5, and the cover body is fixed to the crankcase by bolts 4. However, in actual operation, it is found that if the sealing gasket 5 is placed on the crankcase first and then the cover body is placed, it is easy for the sealing gasket 5 to move, causing the holes on the sealing gasket 5 to be staggered with the holes on the cover body. After multiple alignments, the cover body can be stably installed on the crankcase, which wastes time and reduces work efficiency. Therefore, this device is designed to solve this problem.

[0033] The sealing gasket 5 can be limited by the device. When the top cover 2 is installed, the sealing gasket 5 will not be misplaced, so that the through hole 6 on the sealing gasket 5 can correspond to the bolt 4 on the top cover 2, so that the top cover 2 can be stably installed on the machine body 1. The specific operation is that when the top cover 2 is installed, the sealing gasket 5 is first placed on the machine body 1, and the screw rod through hole 6 on the sealing gasket 5 is sleeved on the outside of the vertical rod 31. The sealing gasket 5 is limited by the vertical rod 31 so that the sealing gasket 5 will not move again. Then install the top cover 2 on the body 1, and the top cover 2 is pressed on the upper surface of the sealing gasket 5. At this time, the upper end of the vertical rod 31 will also penetrate the interior of the top cover 2, and the magnetic block 32 will be extended to the outside of the top cover 2. Since the top cover 2 is made of metal material and can be attracted by the magnetic block 32, when the magnetic block 32 is extended to the outside of the top cover 2, the magnetic block 32 can be rotated and attached to the outer surface of the top cover 2, so as to limit the top cover 2 and always press the top cover 2 against the sealing gasket 5.

[0034] Then use an external electric screwdriver to screw the bolts 4 on the top cover 2 into the inside of the machine body 1 one by one, so that the top cover 2 can be stably installed on the machine body 1, and the sealing performance can be ensured, which is easy to use.

[0035] When the crankcase is in use, the internal oil will continuously move inside it, and metal impurities will be generated in the crankcase. In order to prevent the metal impurities from damaging the internal crankshaft, a magnetic plate 83 is installed inside the top cover 2. The oil continuously moves inside the crankcase and will enter the position of the magnetic plate 83. At the same time, the metal impurities in the oil will also move to the position of the magnetic plate 83. The metal impurities are adsorbed by the magnetic plate 83 to prevent the impurities from continuing to mix with the oil to damage the crankshaft, thereby ensuring that the crankcase can be used normally. When cleaning the inside of the crankcase at a later time, the metal impurities on the magnetic plate 83 can be cleaned off.
