Embodiment Construction
[0029] The present invention is described in conjunction with accompanying drawing and specific embodiment:
[0030] Such as figure 1 As shown, a kind of integral dismounting tool of modular diesel engine power unit 14, described integral dismounting tool comprises two semicircular rings 1 and crossbeam 2; Described two semicircular rings 1 have the same structure; The diameter of the outer circle of the ring 1 is smaller than the diameter of the outer circle of the support boss of the cylinder liner 10, so as to facilitate the assembly of the power unit 14 in the cylinder bore of the body 15 after the installation and disassembly tools; It has a thin-walled groove, and in the middle of the groove, there is a round hole for inserting a crossbeam 2. The crossbeam 2 used to support the big head of the connecting rod 11 is a cylindrical structure processed from a round bar. The length of the crossbeam 2 is equal to the diameter of the semicircular ring 1; the two ends of the c...

The invention belongs to the technical field of diesel engine assembling technology, and provides an integrated dismounting tool and an assembling and disassembling method of a modularized diesel engine power unit (14). The integrated dismounting tool comprises two semi-rings (1) which are same in structure and a cross beam (2), wherein the middle part of each semi-ring (1) is provided with a round hole in which the cross beam (2) can be inserted, the cross beam (2) is of a cylindrical structure, the length of the cross beam (2) is equal to the diameter of the semi-ring (1), two ends of the cross beam (2) are respectively provided with a stepped shaft, the stepped shafts at two ends of the cross beam (2) are respectively inserted into the middle round holes of the two semi-rings (1), and the upper end face of each semi-ring (1) is provided with a boss which is connected with a cylinder jacket (10) in an inserting manner. According to the integrated dismounting tool and the assembling and disassembling method of the modularized diesel engine power unit, the difficulty that the assembly of a piston (9) and a connecting rod (11) cannot be fixed is solved; the integrated dismounting of the modularized diesel engine power unit (14) is achieved, the assembling precision of the diesel engine is improved, the assembling time is shortened, and the production efficiency is improved; furthermore, the integrated dismounting tool of the modularized diesel engine power unit has the advantages of simplicity in structure, reliability in use and simplicity in operation.
Description
technical field [0001] The invention belongs to the technical field of diesel engine assembly, and mainly relates to an integral disassembly tool and an assembly and disassembly method for a modular diesel engine power unit. Background technique [0002] The diesel engine power components in the prior art include a cylinder head, a seal, a cylinder liner, a piston connecting rod assembly, and a cooling water jacket. The cylinder liner is connected to the bottom of the cylinder head, and the upper part of the cylinder liner is located in the cooling water jacket; The piston-rod assembly is located in the cylinder liner and includes a piston, a connecting rod, a crank pin and a large end cap of the connecting rod; the piston is connected to the small end of the connecting rod; the large end of the connecting rod is arc-shaped, It is connected with the large end cover of the connecting rod through the connecting rod bolt, and is sleeved on the crank pin. The force is transmitte...
