Problems solved by technology
[0002] During the maintenance work of the diesel engine, it will involve the disassembly and assembly of some heavy and complicated parts such as the big end of the connecting rod, which will bring great inconvenience to the disassembly work
For the three-section marine connecting rod, the width of the big end of the connecting rod is larger than the inner diameter of the cylinder liner. When it is necessary to lift out the connecting rod-piston assembly and overhaul and replace the bearing bush at the big end of the connecting rod, the big end of the connecting rod cannot be removed from the cylinder liner hole. , you can only separate the rod body from the big end of the connecting rod. If the big end of the connecting rod is not fixed circumferentially, the big end of the connecting rod will rotate, damage the cylinder liner or other parts, and may damage the disassembled parts. Operator life-threatening
During the disassembly and maintenance of the connecting rod of the large medium-speed diesel engine, the disassembly space is small and the operation is inconvenient. The tools used in the prior art do not meet the disassembly requirements, and there are potential safety hazards

The invention discloses a fixing tool for the big end of a connecting rod and a fixing method using the tool, and belongs to the technical field of auxiliary tools for diesel engine assembly. The big end of the connecting rod includes an upper cover, a lower cover, an upper stud connected with the upper cover and a lower stud connected with the lower cover, the big end of the connecting rod is installed on the crankshaft, and the crankshaft A balance block is installed; the fixing tool at the large end of the connecting rod includes two sets of symmetrically arranged fixing units, the fixing unit includes a fixing plate, and the fixing plate includes a first installing plate and a second fixing plate fixedly connected with the first installing plate Two mounting plates, the first mounting plate can be connected with the upper stud or the lower stud, and the second mounting plate can be connected with the balance weight. The fixing tool for the big end of the connecting rod and the fixing method using the tool of the present invention connect the upper stud or the lower stud and the balance weight through the fixing tool to realize the fixing of the big end of the connecting rod, which meets the space requirement for disassembly and assembly, and improves the convenience of operation sex and safety.
Description
technical field [0001] The invention relates to the technical field of auxiliary tools for diesel engine assembly, in particular to a fixing tool for the large end of a connecting rod and a fixing method using the tool. Background technique [0002] During the maintenance work of the diesel engine, it will involve the disassembly and assembly of some heavy and complicated parts such as the big end of the connecting rod, which brings great inconvenience to the disassembly work. For the three-section marine connecting rod, the width of the big end of the connecting rod is larger than the inner diameter of the cylinder liner. When it is necessary to lift out the connecting rod-piston assembly and overhaul and replace the bearing bush at the big end of the connecting rod, the big end of the connecting rod cannot be removed from the cylinder liner hole. , you can only separate the rod body from the big end of the connecting rod. If the big end of the connecting rod is not fixed c...
