Technical Field
The invention relates to the field of machine manufacturing, in particular to a special tool for disassembling a diesel engine piston.
Background
A6240 diesel engine is installed on a GK1C locomotive applied to a port railway, a special tool for disassembling a piston is not used in the prior art, the top of the piston is generally fixed with a connecting plate through a bolt during overhaul of the diesel engine, and the piston is hoisted by arranging a hoisting ring on the connecting plate.
Disclosure of Invention
The invention aims to solve the technical problem of providing a special tool for disassembling a diesel engine piston so as to shorten the time for disassembling the piston and improve the quality of disassembling the piston.
In order to achieve the purpose, the invention adopts the following technical scheme:
a special tool for disassembling a diesel engine piston comprises a horizontal connecting plate, wherein glue for fixedly connecting with the top surface of the piston is arranged at the bottom of the connecting plate; the upper part of the connecting plate is provided with a groove in a cuboid structure, a hanging ring and a horizontal hollow glass tube are hinged in the groove through a horizontal first hinged shaft, and the first hinged shaft passes through the right end of the central axis of the glass tube; the left end surface of the glass tube is provided with an opening;
the hanging ring is positioned in the glass tube; the radius of the glass tube is equal to the distance between the first articulated shaft and the right side wall of the groove;
the top of the groove is provided with a cover plate through a horizontal second hinged shaft openable cover, and the second hinged shaft is arranged at the right end part of the cover plate; the left side wall of the groove is attached with a supporting block for supporting the left end of the cover plate, and the sum of the length of the supporting block in the vertical direction and the thickness of the cover plate is equal to the length of the left side wall in the vertical direction.
The lifting ring is connected with the first hinge shaft through a connecting rod.
The hanging ring is tangent to the inner wall of the glass tube.
The first hinge shaft is located at a center point of the connection plate in a horizontal plane direction.
The connecting plate is a circular plate.
Compared with the prior art, the invention has the advantages that the original bolt point contact is changed into the glue surface contact, so that the stress of the piston is uniform. And because the glass tube is arranged, the perpendicularity between the hoisting direction and the piston can be ensured, and the friction between the piston and the cylinder body is reduced. In addition, rings and glass pipe all can hide the setting in the connecting plate, and pleasing to the eye and accomodate easily.

FIG. 3 is a vertical cross-sectional view of the hoist link shown hidden during use of the present invention;
figure 4 is a vertical cross-section of the hoist ring raised during use of the present invention.
In the figure, the device comprises a connecting plate 1, a connecting plate 2, a groove 3, a lifting ring 4, a first hinge shaft 5, a glass tube 6, a second hinge shaft 7, a cover plate 8, a supporting block 9, a piston 10 and a cylinder body.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 4, the special tool for disassembling the piston of the diesel engine comprises a horizontal connecting plate 1, wherein glue for fixedly connecting with the top surface of a piston 9 is arranged at the bottom of the connecting plate 1; the upper part of the connecting plate 1 is provided with a groove 2 with a cuboid structure, a hanging ring 3 and a horizontal hollow glass tube 5 are hinged in the groove 2 through a horizontal first hinge shaft 4, and the first hinge shaft 4 passes through the right end of the central axis of the glass tube 5; the left end face of the glass tube 5 is provided with an opening;
the hanging ring 3 is positioned in the glass tube 5; the radius of the glass tube 5 is equal to the distance between the first articulated shaft 4 and the right side wall of the groove 2;
the top of the groove 2 is provided with a cover plate 7 through a horizontal second hinged shaft 6 in an openable cover manner, and the second hinged shaft 6 is arranged at the right end part of the cover plate 7; the left side wall of the groove 2 is provided with a supporting block 8 attached to the left end of the cover plate 7, and the sum of the length of the supporting block 8 in the vertical direction and the thickness of the cover plate 7 is equal to the length of the left side wall in the vertical direction.
The lifting ring 3 is connected with the first hinge shaft 4 through a connecting rod.
The hanging ring 3 is tangent with the inner wall of the glass tube 5.
The first hinge shaft 4 is located at a center point of the connection plate 1 in a horizontal plane direction.
The connecting plate 1 is a circular plate.
When the glass tube connecting device is used, the bottom of the connecting plate 1 needs to be fixed to the top of the piston 9 through glue, at the moment, the cover plate 7 is opened, then the hanging ring 3 and the glass tube 5 are rotated to be placed in a vertical state, the glass tube 5 can be tightly attached to the right side wall of the groove 2, and the glass tube 5 is guaranteed to be perpendicular to the connecting plate 1. At this time, the lifting lug of the crane enters the glass tube 5 together with the lifting chain, the lifting lug is connected to the lifting ring 3, and the lifting chain cannot contact the glass tube 5 by adjusting the orientation of the piston 9, so that the lifting chain is ensured to be parallel to the glass tube 5. And controlling the crane to hoist the lifting ring 3, driving the connecting plate 1 to further drive the piston 9 to be separated from the cylinder body 10, and completing the disassembly of the piston 9. When the glass tube lifting device is not needed to be used, the glass tube 5 and the lifting ring 3 are placed in the groove 2, and the cover plate 7 is covered. Even the lifting ring can be directly fixed on the top of the piston 9 and can be regarded as a part of the piston 9, so that the lifting ring 3 can be directly opened for lifting when the piston 9 is disassembled later, and the lifting ring is very convenient and simple.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
