Technical Field

[0001] The invention relates to the field of engine assembly, in particular to an auxiliary bracket for cleaning a crankshaft journal oil passage. Background Art

[0002] The auxiliary bracket for cleaning the crankshaft oil passage is a common device for cleaning engine assembly. Generally, manual cleaning of the crankshaft oil passage requires rotating the crankshaft through the auxiliary bracket for cleaning the crankshaft oil passage so that the oil passage opening faces a convenient direction; at the same time, the brush can pass through the oil passage hole to ensure the cleaning effect. In order to facilitate people to clean the crankshaft oil passage, people invented the auxiliary bracket for cleaning the crankshaft oil passage;

[0003] The existing auxiliary bracket for cleaning the crankshaft neck oil channel has certain disadvantages when used. First, in order to reduce the impact of crankshaft hoisting, the existing auxiliary bracket for cleaning the crankshaft neck oil channel is usually installed with a buffer structure, and the existing buffer structure adopts a folding plate. When in contact, the entire supporting device swings around, which makes the service life of the entire supporting device short. Secondly, the existing supporting device uses rollers to support the crankshaft. When supporting, the crankshaft and the roller directly rub against each other, which will cause the roller to shake, making it inconvenient for people to clean the crankshaft neck oil channel and unable to meet people's usage requirements. For this reason, we propose an auxiliary bracket for cleaning the crankshaft neck oil channel. Summary of the invention

[0004] The main purpose of the present invention is to provide an auxiliary bracket for cleaning the crankshaft journal oil passage, which can effectively solve the problems in the background technology.

[0034] The buffer device includes a buffer plate 6 fixedly mounted on the outer surface of the lower end of the U-shaped support plate 2. Both ends of the buffer plate 6 are provided with a plurality of buffer sheets 7. When the crankshaft contacts the support seat 3, the buffer sheet 7 is deformed and shakes up and down to relieve the impact of crankshaft hoisting.

[0035] The ends of the plurality of groups of buffer sheets 7 away from the buffer plate 6 are intersected with each other, and the outer surfaces of the bottom ends of the plurality of groups of buffer sheets 7 are fixedly mounted with magnet bars 8 .

[0036] The outer surface of the base 1 is provided with a plurality of limiting grooves 9 , and the outer surface of the lower end of the U-shaped support plate 2 is welded with a plurality of limiting strips 10 corresponding to the limiting grooves 9 , and the limiting strips 10 are located inside the limiting grooves 9 .

[0037] The movement of the limiting strip 10 on the limiting groove 9 can prevent the U-shaped supporting plate 2 from shaking in the horizontal direction.

[0038] The support seat 3 is provided with a U-shaped opening 11 , and two groups of U-shaped openings 11 located on the same side of the U-shaped support plate 2 are distributed in an "eight" shape.

[0039] The limiting mechanism includes a plurality of groups of slots 12 , and the plurality of groups of slots 12 are all formed on the inner bottom surface of the U-shaped opening 11 .
