Description
Technical Field
The utility model relates to an assembly technique and equipment field are particularly useful for automobile power assembly concretely relates to manual frock of nimble bent axle oil blanket.
Background
Some engines have poor assembly manufacturability of crankshaft oil seals and lack force points for press fitting, and if the press fitting is directly carried out, the high press fitting force is needed on one hand, and the oil seals are likely to be crushed on the other hand. In order to achieve high yield under the condition of ensuring the integrity of a workpiece, a composite structure form of differential motion of a pressing sleeve and a shaft sleeve and rotation of the pressing sleeve and a driving block is adopted, and in the process of pressing and mounting an oil seal, the oil seal and a crankshaft rotate relatively to form a state that the oil seal is screwed in. The composite press fitting process can smoothly press the oil seal into the crankshaft by applying smaller press fitting force, and the oil seal is not easy to cut edges or damage. If adopt traditional frock, can't reach required qualification rate, also can damage the oil blanket. The tool is specially designed according to the characteristics of the crankshaft oil seal of the engine.

The flexible manual tool for the crankshaft oil seal ensures that the press-fitting force is completely applied to the oil seal through the differential action of the shaft sleeve 1 and the pressing sleeve 2, avoids pressure loss and ensures that the oil seal is pressed and fitted in place.
The flexible manual tool for the crankshaft oil seal ensures that all press-fitting forces are applied to the oil seal through the differential motion of the shaft sleeve 1 and the pressing sleeve 2, avoids pressure loss, ensures that the oil seal is pressed and fitted in place the shaft sleeve 1 is of a chamfer design structure, enables a crankshaft 12 to be smoothly guided into the shaft sleeve 1, can reduce the precision requirements of other positioning structures, reduces the cost, and can meet the coaxiality requirement in the press-fitting process.
In the forward press-fitting process of the press sleeve 2, the rotating shaft 9 rotates, and the driving block 3 drives the crankshaft 12 to rotate, so that a composite press-fitting process is formed, and the phenomenon that the edge cutting or the damage of an oil seal is caused in the press-fitting process is effectively avoided.
The design of the plane bearing 8 ensures that the rotating motion of the rotating shaft 9 is smoother, and the noise in the assembling process is effectively reduced. Meanwhile, the tool has the freedom degree of planar motion, so that the driving block 3 can be smoothly guided into the inner hole of the crankshaft 12, the abrasion between mechanisms is reduced, and the service life of the whole tool can be prolonged.
The utility model discloses a theory of operation: the outer ring of the crankshaft 12 is smoothly guided into the shaft sleeve 1, the driving block 3 is smoothly guided into the inner hole of the crankshaft 12 under the action of the rotating shaft 9 and the plane bearing 8, over-positioning of the tool is avoided, the crankshaft 12 is guaranteed not to be scratched by the tool, the tool performs differential motion and rotary combined motion, and oil seals are fully protected from being crushed
After the technical scheme is adopted, the utility model discloses beneficial effect does: 1. the operation is flexible and convenient due to manual hand-held operation; 2. the crankshaft 12 is more convenient to guide in; 3. the driving block 3 enters the inner hole of the crankshaft 12 for automatic centering; 4. the press-fitting composite action ensures that the workpiece is not trimmed; 5. can be slightly modified according to different types of oil seals, and has wide application.
