Abstract
The utility model discloses an engine jar piston top dead center locking structure, including the cylinder body with install a jar piston and the bent axle in the cylinder body, jar piston below is connected with crankshaft counter balance, crankshaft counter balance passes through crankshaft installation borehole jack dress and is in on the bent axle, it has the blind hole to open on the crankshaft counter balance left end face, and it has the through -hole to open on the left end face of cylinder body, when a jar piston is in the top dead center, the dead in line of through -hole and blind hole, pass the lockpin during the through -hole inserts the blind hole this moment, accomplishes jar piston top dead center locking. Simple structure, processing makes things convenient for, can make things convenient for, pinpoint an engine cylinder body piston top dead center, do not need artificial check and correction in engine assembling process, avoid the human error, make the assembly more reliable.
Description
Technical field
The utility model belongs to technical field of automobile engine, is specifically related to a kind of engine one cylinder piston top dead center locking structure.
Background technology
It needs to be determined that a cylinder piston top dead center in engine assembly process, at present, it is often by, after bent axle and crankshaft pulley wheel assembling well, crankshaft pulley wheel doing a mark and is directed at a mark point on front cover shell, a well rear cylinder piston is in top dead center, is seen by artificialvision and determine; Manually determine that comparison is time-consuming, and there is labile factor, it is possible to there will be to inaccurate or leakage to situation, cause assembling error, cause engine igniting time mistake.
Practical novel content
The utility model aims to provide a kind of energy locking structure convenient, accurately location engine one cylinder piston top dead center.
For this reason, the technical scheme that the utility model adopts is: a kind of engine one cylinder piston top dead center locking structure, cylinder piston and the bent axle comprising cylinder body and be arranged in cylinder body, being connected with balance weight for crankshaft below a described cylinder piston, described balance weight for crankshaft is sleeved on described bent axle by crankshaft installed hole; Described balance weight for crankshaft left side has blind hole, the left side of cylinder body has through hole; When a cylinder piston is in top dead center, described through hole overlaps with the axis of blind hole, now by lock pin through, in through hole insertion blind hole, completing a cylinder piston top dead center locking.
On the basis of such scheme, being provided with screw thread in described blind hole, described lock pin is bolt lock pin.
The beneficial effects of the utility model are: structure is simple, easy to process, can location engine one cylinder piston top dead center convenient, accurate; Engine assembly process does not need artificial check and correction, avoids human error, make assembling more reliable.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is the utility model one cylinder piston shaft mapping.
Embodiment
Below by embodiment and by reference to the accompanying drawings, the utility model is described in further detail:
As shown in Fig. 1��2, a kind of engine one cylinder piston top dead center locking structure, form primarily of cylinder body a and the cylinder piston 1 being arranged in cylinder body a and bent axle 2, being connected with balance weight for crankshaft 3 below a cylinder piston 1, balance weight for crankshaft 3 is provided with crankshaft installed hole, balance weight for crankshaft 3 is sleeved on bent axle 2 by crankshaft installed hole, and as shown in Figure 1, when balance weight for crankshaft 3 is in top dead center, left side is corresponding with cylinder body a left side, and right side is corresponding with cylinder body a right side; Balance weight for crankshaft 3 left side has blind hole, the left side of cylinder body has through hole; When a cylinder piston 1 is in top dead center, through hole overlaps with the axis of blind hole, now by lock pin 4 through, in through hole insertion blind hole, completing a cylinder piston 1 top dead center locking.
Better, being provided with screw thread in blind hole, lock pin 4 is bolt lock pin.
