Abstract
The utility model relates to a disassembly tool of a bearing bush of a connecting rod, which is applied to the condition that the bearing bush or a bearing is disassembled from the inside of a bearing seat during mechanical maintenance. Both ends of the upper plane of a base are respectively vertically welded with an upright post, the top ends of the two upright posts are welded with an upper transverse beam, and the upper transverse beam is parallel to the upper plane of the base; a flat plate is welded between the two upright posts and is parallel to the upper plane of the base; and the middle part of the flat plate is provided with a circular through hole. The diameter of the circular through hole is slightly greater than the outer diameter of the bearing bush. The bearing bush and the bearing seat needing to be disassembled are placed at the upper plane of the flat plate, and the bearing bush is opposite to the circular through hole of the flat plate; and the upper end face of the bearing bush is provided with a circular shim plate, and the outer diameter of the shim plate is slightly smaller than the outer diameter of the bearing bush. A jack is fixed between the shim plate and the upper transverse beam, and a mandril of the jack is peaked at the upper plane of the shim plate. The mandril is extended out when the jack is operated, and the bearing bush is peaked into the circular through hole of the flat plate. The disassembly tool has the effects that the bearing bush can be taken out of the bearing seat, and the disassembly tool of the bearing bush of the connecting rod is suitable for being used at a maintenance site. The structure is simple, and the cost is low.
Description
Technical field
The utility model relates to the flight-line maintenance technical field, particularly a kind of in the bearing block specific purpose tool of dismounting bearing shell or dismounting bearing.
Background technology
Connecting rod bearing shell is a kind of as sliding bearing, and bearing shell is in bearing block, and what bearing shell and bearing block adopted between the two is interference fit.When the maintain and replace bearing shell, bearing shell need be disassembled from bearing block.At present, rely on simple manual method almost it directly can't be taken out bearing shell from bearing block, adopt cooled with liquid nitrogen or dedicated hydraulic equipment to be removed usually, but some working site does not satisfy the requirements.Bearing shell and bearing block can only be delivered to the dismounting of specialized maintenance place, prolong the maintenance of equipment time.
The utility model content
The purpose of this utility model is: a kind of connecting rod bearing shell extracting tool is provided, utilizes the thrust of jack, bearing shell is separated with bearing block.Improve maintenance work efficient.
The technical solution adopted in the utility model is: the connecting rod bearing shell extracting tool, mainly form by base, column, flat board, backing plate, jack and entablature, it is characterized in that: on base the two ends, plane respectively vertical welding be connected to a root post, be welded with an entablature on the top of two root posts, the last plane parallel of entablature and base; Between two root posts, be welded with flat board, plane parallel on flat board and the base; A manhole is arranged at the middle part of flat board.The slightly larger in diameter of manhole is in the bearing shell external diameter.The bearing shell and the bearing block of needs dismounting are put into the dull and stereotyped plane of going up, and bearing shell is relative with dull and stereotyped manhole; The circular shim pad is on the upper surface of bearing shell, and the external diameter of backing plate is slightly less than the bearing shell external diameter.Be fixed with a jack between backing plate and entablature, the push rod of jack withstands on the last plane of backing plate.The operation jack stretches out push rod, and bearing shell is headed in the dull and stereotyped manhole.
In order to strengthen dull and stereotyped anti-pressure ability, vertical welding is connected to support column between flat board and base, and support column is in the both sides of dull and stereotyped manhole.
In order to strengthen the bending resistance of entablature, between the column of entablature and both sides, be welded with brace respectively.
The beneficial effects of the utility model: the utility model connecting rod bearing shell extracting tool, bearing shell can be taken out from bearing block, be fit to maintenance sites and use.Simple in structure, cost is low.

The specific embodiment
Embodiment 1: the connecting rod bearing shell extracting tool that is 58mm with a dismounting bearing shell external diameter is an example, and the utility model is described in further detail.
Consult Fig. 1.The utility model connecting rod bearing shell extracting tool mainly is made up of base 1, column 3, flat board 4, backing plate 7, jack 8 and entablature 10.On cuboid base 1 two ends, plane respectively vertical welding be connected to a root post 3, be welded with an entablature 10 on the top of two root posts 3, between the column 3 of entablature 10 and both sides, be welded with brace 9 respectively.The last plane parallel of entablature 10 and base 1.
Between two root posts 3, be welded with flat board 4, plane parallel on flat board 4 and the base 1; There is a manhole at middle part dull and stereotyped 4.The diameter 60mm of manhole.Vertical welding is connected to support column 2 between flat board 4 and base 1, and support column 2 is in the both sides of dull and stereotyped 4 manholes.
The bearing shell 6 and the bearing block 5 of needs dismounting are put into plane on dull and stereotyped 4, and bearing shell 6 is relative with the manhole of flat board 4; In the upper surface of bearing shell 6 circular shim 7 is arranged, the external diameter 56mm of backing plate 7.Be fixed with a hand-hydraulic jack 8 between backing plate 7 and entablature 10, the push rod of jack 8 withstands on the last plane of backing plate 7.
