Description
Technical Field
The utility model relates to an assembly technique and equipment field are particularly useful for being applicable to car, engineering machine tool and power assembly, concretely relates to semi-automatic frock of high qualification rate bent axle oil blanket.
Background
The assembly manufacturability of the crankshaft oil seal of the diesel engine is poor, the force application point of press fitting is lacked, if the press fitting is directly carried out, high press fitting force is needed on the one hand, and the oil seal is 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 semi-automatic tool for the high-qualification-rate crankshaft oil seal has the advantages of convenience in guiding and centering, small press fitting force, simplicity and convenience in operation, flexibility in application, no damage to workpieces and improvement of qualification rate.
Disclosure of Invention
An object of the utility model is to prior art's defect and not enough, provide a nimble manual frock of bent axle oil blanket.
In order to achieve the above purpose, the utility model adopts the following technical scheme: semi-automatic frock of high qualification rate bent axle oil blanket, it contains bent axle oil blanket 1, drive block 2, axle sleeve 3, presses cover 4, pivot 5, spring 6, flat bearing 7, transition piece 8, connecting block 9, bent axle 10, handle 11, pivot 5 covers in axle sleeve 3, and drive block 2 is connected to 5 front ends of pivot, 4 pressures of pressing cover on axle sleeve 3, press 4 front ends of cover to be connected with bent axle oil blanket 1, 5 middle parts of pivot are equipped with spring 6, 5 tail ends of pivot are equipped with flat bearing 7, pivot 5 is connected to 8 right-hand members of transition piece, connecting block 9 is connected to 8 left ends of transition piece, handle 11 is connected to 9 left ends of connecting block, bent axle 10 is connected on drive block 2.
The semi-automatic tool for the high-yield crankshaft oil seal ensures that the press-fitting force is completely applied to the oil seal through the differential action of the shaft sleeve 3 and the pressing sleeve 4, avoids pressure loss and ensures that the oil seal is pressed and fitted in place.
The shaft sleeve 3 is of a chamfer design structure, so that the crankshaft 10 can be smoothly guided into the shaft sleeve 3, the precision requirements of other positioning structures can be reduced, the cost is reduced, and the coaxiality requirement in the press mounting process can be met.
In the forward press-fitting process of the press sleeve 4, the rotating shaft 5 rotates, and the driving block 2 drives the crankshaft 10 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 7 ensures that the rotating motion of the rotating shaft 5 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 2 can be smoothly guided into the inner hole of the crankshaft 10, 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 10 is smoothly guided into the shaft sleeve 3, the driving block 2 is smoothly guided into the inner hole of the crankshaft 10 under the action of the rotating shaft 5 and the plane bearing 7, over-positioning of the tool is avoided, the crankshaft 10 is guaranteed not to be scratched by the tool, and the tool performs differential motion and rotary combined motion, so that an oil seal is fully protected from being crushed.
After the technical scheme is adopted, the utility model discloses beneficial effect does: 1. The crankshaft 10 is more convenient to guide; 2. the driving block 2 enters the inner hole of the crankshaft 10 to be automatically centered; 3. the press-fitting composite action ensures that the workpiece is not trimmed; 4. can be slightly modified according to different types of oil seals, and has wide application.
