Description
Technical field
The utility model relates to engine maintenance frock field, relates to a kind of replacing frock of high-pressure oil pump of engine specifically, and the high-pressure oil pump being applicable to the JX4D30 engine of JMC is changed.
Background technology
High-pressure oil pump is one of important spare part of engine, and whether its normal work directly affects properties and the index of engine, if this part generation problem, so must change this part.But current most of oil pump is driven by reliable timing driving system, generally to tear timing system part open when more scavenge oil pump, timing system is ressembled again after changing oil pump, and the parts such as water tank of will dismantling when tearing timing cover plate open, can cause the partition losses of cooling fluid thus.But, for the timing driving system of complexity, a lot of man-hours to be spent when dismounting, and onboard dismounting time by the restriction of operating space, can cause completing more changing jobs.This patent is exactly the problem that difficulty changed by the high-pressure oil pump of JX4D30 engine in order to solve JMC.
Utility model content
The purpose of this utility model is to solve the problem, and provides a kind of replacing frock of high-pressure oil pump of engine.The problem of difficulty changed by the high-pressure oil pump solving the JX4D30 engine of JMC.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of replacing frock of high-pressure oil pump of engine, comprise fixed head, manhole is had in the middle part of fixed head, this manhole size is mated with the size of high-pressure oil pump, the surrounding of fixed head is provided with fixing hole, be provided with two hold-down bolts at the edge of manhole, be also provided with a stud post and a fixed hook at manhole edge.
One end headband nut of described fixed hook, is passed in the through hole on fixed head, and there is a hook one end for fixing high-pressure oil pump gear in addition; Stud post one end headband nut, is passed in the through hole on fixed head, in addition the screwed hole of one end on fixing high-pressure oil pump gear.
The beneficial effects of the utility model are: the replacing that 1, can complete oil pump when not tearing timing system and other part open.2, improve the operating efficiency of more scavenge oil pump, when without frock, more scavenge oil pump needs about 10 ~ 12 man-hours of continuous operation, about after using frock, required time can shorten to for 2 man-hours.4, cooling fluid, gear chamber pad equal loss is decreased.5, this device structure is simple, reduces maintenance cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1.
A kind of replacing frock of high-pressure oil pump of engine, comprise fixed head 1, manhole is had in the middle part of fixed head 1, this manhole size is mated with the size of high-pressure oil pump, the surrounding of fixed head is provided with fixing hole 6, be provided with two hold-down bolts 2 at the edge of manhole, be also provided with a stud post 4 and a fixed hook 3 at manhole edge.
One end headband nut of described fixed hook 3, is passed in the through hole on fixed head 1, and there is a hook one end for fixing high-pressure oil pump gear in addition; Stud post 4 one end headband nut, is passed in the through hole on fixed head 1, in addition the screwed hole of one end on fixing high-pressure oil pump gear.
Operation instruction of the present utility model: by the peep pole of high-pressure oil pump, the fixed head of mounting tool, is fixed oil pump gear by fixed hook and studs, is pressed on high-pressure oil pump sprocket wheel and gear by chain by two hold-down bolts.Then the replacing of oil pump is carried out.
Concrete high-pressure oil pump dismounting step is as follows:
The first step: taken apart by oil pump inspection door, up time dials dynamic crankshaft, is transferred to oil pump gear and makes the screwed hole on oil pump gear just expose chain treaty 1 ~ 3 millimeter place by tensioning guide plate side.
Second step: fixed crankshaft.
3rd step: until bottom in screwed hole stud post being screwed to oil pump gear.
4th step: the fixing hole that bolt is worn on fixed head is installed to fixed head on the oil pump peep pole of gear chamber cover, fixed hook is suspended on oil pump gear (guarantees that the faceted normal direction of hook head portions points to the center of oil pump shaft); On the bolt that two nuts are screwed to fixed hook respectively and studs, moment of torsion 10Nm; The hold-down bolt of two M6 is screwed in the screwed hole of fixed head, makes it compress chain, moment of torsion 2 ~ 5Nm.
5th step: the associated fasteners pulling down oil pump shaft nut and oil pump, uses copper rod to be pounded out by injection pump.
6th step: install new injection pump by assembling code requirement, oil pump shaft nut screwing clamping is to appointment moment of torsion.Whole service work terminates.
What embodiment of the present utility model was announced is preferred embodiment; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and change, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
