Description
Technical Field
The utility model belongs to the technical field of the engine, concretely relates to diesel injector extracting tool.
Background
The engine needs to be maintained according to the specified time, wherein the oil injector needs to be detached for an atomization test, and after the engine runs for a period of time, the oil injector and the protective pipe are often corroded and adhered together, so that the oil injector cannot be detached smoothly. In the prior art, a common and feasible method for disassembling an oil injector comprises the following steps: the cylinder cover is completely disassembled, and the nozzle at the bottom of the oil sprayer is knocked from the lower part of the cylinder cover to separate the oil sprayer from the protective pipe. Other fuel injector removal tools include: the self-made joint internal thread is connected with the oil sprayer head external thread, and the self-made joint internal thread and the oil sprayer head external thread are repeatedly lifted upwards by hands, so that the method is very difficult to disassemble, and part of the oil sprayer cannot be smoothly disassembled, thereby causing great trouble to maintenance service.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a diesel injector extracting tool.
The utility model adopts the following technical scheme for accomplishing the above purpose:
a kind of engine fuel injector extracting tool, the extracting tool has supporting the cylinder; the supporting cylinder body is a semicircular cylinder body; the two supporting cylinder bodies are buckled to form a cylindrical cylinder body; a tensioning block is welded on the lower end face of each supporting cylinder; the two tensioning blocks of the two supporting cylinders are symmetrically arranged, and the two tensioning blocks are arranged corresponding to the oil sprayer protective tube cross groove; a fixing plate is welded on each supporting cylinder; the upper ends of the two supporting cylinder bodies are positioned in the circular grooves on the lower end surface of the fixing frame; the fixing frame is a cylinder; the circular groove is positioned in the center of the lower end surface of the fixing frame; an outer hexagonal joint is welded on the upper end face of the fixing frame; an inner square interface is arranged in the outer hexagonal joint; the fixing frame is fixedly integrated with a fixing plate welded on the supporting cylinder body.
The utility model provides a diesel engine sprayer extracting tool utilizes standard open spanner to rotate the outer hexagonal interface of mount top or rotates the interior cubic interface of mount top with standard torque wrench, extracts sprayer pillar and sprayer together through ascending effort. The utility model has the characteristics of economical and practical, simple structure, simple manufacture, convenient operation, safe and reliable, application range is wide.

Detailed Description
The invention is described in connection with the accompanying drawings and the embodiments:
as shown in fig. 1, an engine fuel injector remover tool has a support cylinder 4; with reference to fig. 4 and 5, the supporting cylinder 4 is a semicircular cylinder; the two supporting cylinder bodies are buckled to form a cylindrical cylinder body; a tensioning block is welded on the lower end face of each supporting cylinder; the two tensioning blocks of the two supporting cylinders are symmetrically arranged, and the two tensioning blocks are arranged corresponding to the oil sprayer protective tube cross groove; a fixing plate is welded on each supporting cylinder; the upper ends of the two supporting cylinder bodies are positioned in the circular grooves on the lower end surface of the fixing frame; the fixing frame is a cylinder; the circular groove is positioned in the center of the lower end surface of the fixing frame; an outer hexagonal joint is welded on the upper end face of the fixing frame; an inner square interface is arranged in the outer hexagonal joint; the fixing frame is fixedly integrated with a fixing plate welded on the supporting cylinder body.
When the oil sprayer supporting pipe connecting device is used, the supporting ring 4 and the fixing frame 1 are detached, the tensioning blocks below the supporting ring 4 are respectively inserted into the cross grooves of the oil sprayer supporting pipe, the supporting ring 4 is inserted into the circular groove below the fixing frame 1, the fixing frame 1 and the supporting ring 4 are connected together through the bolts 2 and the nuts 3, the oil sprayer supporting pipe and the inside of a cylinder cover belong to threaded connection, an external hexagonal connector above the fixing frame 1 is rotated through a standard open-end wrench or an internal square connector above the fixing frame 1 is rotated through a standard torque wrench, the oil sprayer supporting pipe and the oil sprayer are pulled out together through upward acting force, and after the oil sprayer supporting pipe connecting device is pulled out, an atomization test can be.
The oil injector and the protective pipe can be pulled out from the cylinder cover by upward acting force by rotating the outer hexagonal interface or the inner tetragonal interface above the fixed frame 1 by using a standard tool. Therefore, the disassembling tool is suitable for disassembling the oil sprayer protective pipe provided with the groove, is not only suitable for disassembling a single oil sprayer, and improves the applicability of the disassembling tool, and meanwhile, the cylinder cover does not need to be completely disassembled in the disassembling process, and the performability of the disassembling tool is improved.
