Abstract
The utility model discloses a special tool for disassembling a crankshaft pulley of a diesel motor. The special tool comprises a threaded rod and a flange; one end of the threaded rod is provided with a hexagon head; a screw hole is arranged at the center of the flange and the threaded rod is arranged in the screw hole at the center of the flange; a plurality of through holes are arranged on the flange along the circumferential direction; and the positions of the through holes(a plurality of) match with the positions of the screw holes of the crankshaft pulley. In order to accord with the screw holes on the crankshaft pulley, twelve through holes at equal intervals are arranged on the flange along the circumferential direction. With the special tool, the crankshaft pulley can be disassembled conveniently, the tool is high in disassembling efficiency, and the operation process is safe without damages to the crankshaft pulley, thus reducing examine and repair costs.
Description
Technical field
The utility model relates to a kind of Diesel engine crank pulley dismounting specific purpose tool.
Background technology
All kinds of faults can occur in the Diesel engine running, wherein when the leakage of oil of bent axle Front oil seal, then need pull down crank pulley, could change oil sealing.Because crank pulley is a pyramid type structure and to be connected cooperation be interference fit with bent axle, therefore the crank pulley dismounting is difficult, usually use the powerful hard draw of triangle plucking or use the operation of oxygen heated baking, use the said method dismounting often crank pulley to be pulled, damaged, simultaneously also parts such as the gear of Diesel engine, axle, bearing have been implemented annealing in process in the heated baking operation process, reduce their intensity, hardness and rigidity, had influence on machine performance and life-span.Therefore the crank pulley dismounting is wasted time and energy, and efficient is extremely low, also has potential safety hazard, need change spare part when crank pulley is removing damaged, has increased the cost of overhaul.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Diesel engine crank pulley dismounting specific purpose tool, this instrument of utilization can crank pulley for convenience detach, removal efficiency height, operation process safety, and can not damage crank pulley in the field-strip, reduce the cost of overhaul.
For solving the problems of the technologies described above, the utility model Diesel engine crank pulley dismounting specific purpose tool comprises screw rod and ring flange, described screw rod one end is a turret head, described ring flange center has screw, described screw rod is positioned at the screw at described ring flange center, described ring flange along the circumferential direction has some through holes, the position of described some through holes and the screwhole position of crank pulley coupling.
For consistent with the screw of crank pulley, described ring flange along the circumferential direction has the through hole of 12 spacing five equilibriums.
Because the utility model Diesel engine crank pulley dismounting specific purpose tool has adopted technique scheme, be about to screw rod and ring flange and form extracting tool, screw rod one end is turret head and the screw that is positioned at the ring flange center, and ring flange along the circumferential direction can have the through hole with crank pulley screw coupling; When this instrument uses, the some through holes that adopt bolt to penetrate ring flange are screwed in the screw of crank pulley, ring flange and crank pulley are become one, the screw that screw rod is screwed into the ring flange center makes screw rod withstand the rotating shaft of crank pulley, continues to turn screw rod and ring flange and crank pulley can be taken out of in the lump.So utilize this instrument can crank pulley for convenience detach, the removal efficiency height, operation process safety, and can not damage crank pulley in the field-strip, reduced the cost of overhaul.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the front view of the utility model Diesel engine crank pulley dismounting specific purpose tool,
Fig. 2 is the vertical view of the utility model Diesel engine crank pulley dismounting specific purpose tool.
The specific embodiment
As depicted in figs. 1 and 2, the utility model Diesel engine crank pulley dismounting specific purpose tool comprises screw rod 1 and ring flange 3, described screw rod 1 one ends are turret heads 2, described ring flange 3 centers have screw, described screw rod 1 is positioned at the screw at described ring flange 3 centers, described ring flange 3 along the circumferential direction has some through holes 4, the position of described some through holes 4 and the screwhole position of crank pulley coupling.
For consistent with the screw of crank pulley, described ring flange 3 along the circumferential direction has the through hole 4 of 12 spacing five equilibriums.
The utility model Diesel engine crank pulley dismounting specific purpose tool is formed extracting tool with screw rod and ring flange, and screw rod one end is turret head and the screw that is positioned at the ring flange center, and ring flange along the circumferential direction can have the through hole with crank pulley screw coupling; When this instrument uses, the some through holes that adopt bolt to penetrate ring flange are screwed in the screw of crank pulley, ring flange and crank pulley are become one, the screw that screw rod is screwed into the ring flange center makes screw rod withstand the rotating shaft of crank pulley, uses spanner to continue to turn screw rod and ring flange and crank pulley can be taken out of in the lump.So utilize this instrument can crank pulley for convenience detach, the removal efficiency height, operation process safety, and can not damage crank pulley in the field-strip, reduced the cost of overhaul.
