Description

Gear pump disassembly tool

Technical Field

0001. The utility model relates to the technical field of gear pumps, in particular to a gear pump disassembly tool.

Background

The gear pump has the advantages of reliable operation, strong pollution resistance, good self-priming performance and the like, and is a hydraulic element widely applied to engineering machinery. After the gear pump is used for a long time, the internal temperature of the gear pump can be gradually increased to damage the internal sealing ring, so that the service life of the sealing ring is reduced, the working efficiency of the gear pump is reduced, and the sealing ring needs to be replaced periodically to ensure the working efficiency of the gear pump.

0003. Usually, for gear pump dismantlement, because connect comparatively closely can make the joint connection department adhesion on the casing, need use the opener to pick up, it is very laborious, and very consuming time.

Disclosure of Invention

0004. The utility model provides a gear pump dismounting tool, which can quickly realize the dismounting of a gear pump by dismounting a pump chuck and clamping the joint of a gear pump shell from two sides.

0005. In order to solve the technical problems, the utility model provides the following technical scheme:

the utility model discloses a gear pump disassembly tool, which comprises a bottom plate, wherein the bottom plate is provided with a gear pump; the hydraulic cylinder is fixedly connected to the bottom plate; the manual unidirectional hydraulic pump is fixedly connected to the bottom plate and communicated with the hydraulic cylinder through a hydraulic oil pipe, and a pump disassembling device is arranged at the telescopic end of the manual unidirectional hydraulic pump; the pump disassembly device comprises two pump disassembly chucks which are oppositely arranged, wherein one pump disassembly chuck is fixedly connected with the telescopic end of the hydraulic cylinder, and the other pump disassembly chuck is fixedly connected with the bottom plate.

0006. Further, the pump disassembly chuck comprises a fixing plate, and a triangular chuck is fixed on the fixing plate along the vertical direction.

0007. Further, the triangular chuck is an isosceles triangle, the bottom surface of the triangular chuck and the fixing plate are integrally arranged, and the vertex angle of the triangular chuck is 30-60 degrees.

0008. Further, a backing plate is arranged below the pump disassembly device.

0009. Further, an oil pressure gauge is also communicated with the manual one-way hydraulic pump.

0010. The beneficial effects achieved by the utility model are as follows:

through setting up the tip and being the dismantlement frock of triangle form, it is direct to place the gear pump in two pump chucks of tearing open, promotes through the pneumatic cylinder and makes two pump chucks of tearing open the pump case clearance of pump together extrusion gear pump, can realize the quick dismantlement of gear pump, can conveniently control the oil feeding speed of pneumatic cylinder through setting up manual unidirectional hydraulic pump, simultaneously through setting up the backing plate, convenient change after the excessive wearing and tearing of number of times.

FIG. 1 is a schematic diagram of the structure of the patent.

Description of the embodiments

0012. The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.

0013. As shown in fig. 1, a gear pump disassembly tool includes a base plate 10; the hydraulic cylinder 40 is fixedly connected to the bottom plate 10, and a pump dismounting device 30 is arranged at the telescopic end of the hydraulic cylinder 40;

a manual unidirectional hydraulic pump 20 fixedly connected to the bottom plate 10 and communicated with the hydraulic cylinder 20 through a hydraulic oil pipe; the pump disassembling device 30 comprises two pump disassembling chucks 301 which are oppositely arranged, wherein one pump disassembling chuck 301 is fixedly connected to the telescopic end of the hydraulic cylinder 20, and the other pump disassembling chuck 301 is fixedly connected to the bottom plate 10.

0014. Specifically, in use, the gear pump to be disassembled, from which the connecting bolts are disassembled, is placed between the pump disassembling devices 30, the pump disassembling chucks 301 are aligned to the joint of the gear pump shells, and the manual one-way hydraulic pump 20 is manually pressed, so that the two pump disassembling chucks 301 are squeezed into the space between the pump shells to be disassembled from two sides to separate the shells.

0015. For convenient installation of the pump disassembly clamp 301, the pump disassembly clamp 301 comprises a fixing plate 3011, and for convenient separation of the pump housing, a triangular clamp 3012 is fixed on the fixing plate 3011 along the vertical direction.

0016. Meanwhile, in order to facilitate separation, the triangular chuck 3012 is an isosceles triangle, the bottom surface of the triangular chuck is integrally arranged with the fixing plate 3011, and the vertex angle of the triangular chuck is 30-60 degrees, and is usually 40 degrees.

0017. In order to avoid that the wear of the base plate cannot be repaired after long-term use, a backing plate 50 is arranged below the pump dismounting device 30 on the base plate 10.

0018. In order to facilitate observing the pressure of the hydraulic cylinder, the hydraulic pressure gauge 201 is also connected to the manual unidirectional hydraulic pump 20.

0019. Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments.
