Abstract
The present invention relates to engine maintenance frock field, be specifically related to the replacing frock of JX4D30 high-pressure oil pump of engine, comprise fixed head, fixed head middle part has manhole, this manhole size is mated with the size of high-pressure oil pump, the surrounding of fixed head is provided with fixing hole, is provided with two hold-down bolts at the edge of manhole, is 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, and one end is for the screwed hole on fixing high-pressure oil pump gear in addition. The present invention can complete the replacing of oil pump in the situation that not tearing timing system and other part open. Improve the more operating efficiency of scavenge oil pump. Cooling fluid, gear chamber pad equal loss are reduced. This device structure is simple, has reduced maintenance cost simultaneously.
Description
Technical field
The present invention relates to engine maintenance frock field, relate to specifically a kind of replacing frock of high-pressure oil pump of engine, the high-pressure oil pump that is 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 must be changed this part so. But current most of oil pump is to drive by reliable timing driving system, generally in the time of scavenge oil pump more, to tear timing system part open, after changing oil pump, ressemble again timing system, and the parts such as water tank of will dismantling while tearing timing cover plate open, can cause the part loss of cooling fluid thus. But, for complicated timing driving system, in the time of dismounting, a lot of man-hours to be spent, and the restriction of operating space can be subject to when dismounting onboard, cause completing more changing jobs. This patent is exactly that the high-pressure oil pump of the JX4D30 engine in order to solve JMC is changed difficult problem.
Summary of the invention
The object of the invention is to address the above problem, a kind of replacing frock of high-pressure oil pump of engine is provided. The high-pressure oil pump that has solved the JX4D30 engine of JMC is changed difficult problem.
In order to realize object of the present invention, the technical solution used in the present invention is:
A kind of replacing frock of high-pressure oil pump of engine, comprise fixed head, fixed head middle part has manhole, 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, and one end is for the screwed hole on fixing high-pressure oil pump gear in addition.
Beneficial effect of the present invention is: 1, can in the situation that not tearing timing system and other part open, complete the replacing of oil pump. 2, improved the more operating efficiency of scavenge oil pump, when without frock, more scavenge oil pump needs approximately 10 ~ 12 man-hours of continuous operation, use frock after required time can shorten to about 2 man-hours. 4, cooling fluid, gear chamber pad equal loss have been reduced. 5, this device structure is simple, has reduced maintenance cost simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment: referring to Fig. 1.
A kind of replacing frock of high-pressure oil pump of engine, comprise fixed head 1, fixed head 1 middle part has manhole, 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 nuts, are passed in the through hole on fixed head 1, and one end is for the screwed hole on fixing high-pressure oil pump gear in addition.
Operation instruction of the present invention: by the peep pole of high-pressure oil pump, the fixed head of mounting tool, fixes oil pump gear by fixed hook and studs, by two hold-down bolts, chain is pressed on high-pressure oil pump sprocket wheel and gear. Then carry out the replacing of oil pump.
Concrete high-pressure oil pump dismounting step is as follows:
The first step: oil pump inspection door is taken apart, and up time dials dynamic crankshaft, is transferred to by oil pump gear the screwed hole making on oil pump gear and has just exposed 1 ~ 3 millimeter of place of chain treaty by tensioning guide plate side.
Second step: fixed crankshaft.
The 3rd step: stud post is screwed in the screwed hole of oil pump gear until bottom.
The 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 the center of the faceted normal direction sensing oil pump shaft of hook head portions); Two nuts are screwed to respectively on the bolt and studs of fixed hook, 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.
The 5th step: pull down the associated fasteners of oil pump shaft nut and oil pump, use copper rod that injection pump is pounded out.
The 6th step: install new injection pump by assembling code requirement, oil pump shaft nut screwing clamping is to specifying moment of torsion. Whole service work finishes.
What embodiments of the invention were announced is preferred embodiment, but is not limited to this, those of ordinary skill in the art; very easily, according to above-described embodiment, understand spirit of the present invention, and make different amplifications and variation; but only otherwise depart from spirit of the present invention, all in protection scope of the present invention.
