Description
Technical field
The utility model relates to technical field of engines, particularly relates to a kind of high explosion pressure engine fuel injector cover mounting or dismounting integration tool.
Background technology
Current each producer is the casting technique sex chromosome mosaicism solving direct fuel-injection engine cylinder head, cylinder cap fuel injector installing hole is designed to thimble hole more, fuel injector and fuel injector sleeve are arranged in the oil injector hole in cylinder head, and the O type circle that adopts seals more, for this structure, it is common fault that the aging or fuel injector sleeve of O type circle rubber parts lost efficacy, and the difficulty of fuel injector sleeve dismounting when changing can produce larger impact to maintenance time, cost and user satisfaction, directly affects its economic benefit.
Fuel injector sleeve is thin-wall part, fuel injector and cold water is separated on the one hand, and another aspect is again the medium that cooling water cools fuel injector, cost of manufacture and difficulty larger.For the mounting or dismounting problem of fuel injector sleeve, installation method does not generally have too big difference, and conventional installation method makes it in place with copper rod or aluminium bar impact fuel injector sleeve upper surface; And the method for dismounting difference of fuel injector sleeve is comparatively large, it is pull down cylinder head that existing processing mode generally comprises following three kinds: one, with the mode violence dismounting of beaing; Two is do not tear cylinder head open, and with rising, bar compresses fuel injector sleeve inwall, utilizes frictional force to extract fuel injector sleeve; Three is do not tear cylinder cap open, temporarily in the tapping of fuel injector sleeve inwall, then is back-outed by threaded engagement.
For first kind of way, frequently dismantle cylinder head, cylinder head bolt replacement frequency increases, and cost is high, and dismounting cylinder head is time-consuming; For the second way, the bar thrust that rises is wayward, too smallly cannot extract, and excessive that fuel injector sleeve may be caused to be out of shape is excessive, so that dismounting is more difficult; For the third mode, interim tapping is time-consuming, and if produce chip fall into the normal use that combustion chamber can affect engine; Even if the front thing of consideration tapping blocks stomidium under fuel injector sleeve, but the uncertainty of manual operation, still may block lower stomidium because forgetting and produce adverse consequences.
Utility model content
The utility model provides a kind of high explosion pressure engine fuel injector cover mounting or dismounting integration tool, solves the problem that dismounting fuel injector sleeve need dismantle cylinder head; When solving employing fashion of extrusion dismounting fuel injector sleeve, the uppity problem of dynamics; When solving interim tapping dismounting fuel injector sleeve, consuming time and cleannes are difficult to the problem ensured, have evaded the uncertainty that manual operation brings simultaneously.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of high explosion pressure engine fuel injector cover mounting or dismounting integration tool, comprise screw rod and sleeve, described screw rod upper end is provided with for spacing seam, described screw rod lower end pre-threaded, overlap with prefabricated female high explosion pressure engine fuel injector and coordinate, described fuel injector sleeve is dismantled; Described screw rod and the sleeve play the guiding role assemble, and described sleeve lower end is provided with the seam for acting on described fuel injector sleeve upper surface, in order to be arranged in oil injector hole by described fuel injector sleeve.
Described screw rod is screwed in described fuel injector sleeve, described screw rod lower end and described fuel injector sleeve carry out threaded engagement, when described screw rod upper end seam contacts with mounting hole of oil sprayer upper surface, continue turn screw rod, described fuel injector sleeve is because producing pulling force upwards with the relative motion of described screw rod, thus be removed, do not need to draw, the effort operation such as to pull out, then O type circle is taken out, the utility model is used to dismantle high explosion pressure engine fuel injector cover, do not need dismounting cylinder head or interim tapping, time saving and energy saving, easy and simple to handle, chip etc. can not be produced, do not affect parts cleannes, that can evade thinks that operating the uncertainty brought reduces to minimum, to ensure the uniformity installing and removing described fuel injector sleeve simultaneously.
Preferably, described screw rod lower end length is less than the described mounting hole of oil sprayer degree of depth, avoids screw rod lower end to go deep into the length of described mounting hole of oil sprayer long, destroys the pass keyhole of crucial plane bottom mounting hole of oil sprayer and lower end.
Preferably, described sleeve upper end outer wall is provided with the seam coordinated with cylinder head, the existence of this confined planes, and when can avoid manual operation to a certain extent, dynamics controls the improper and described fuel injector sleeve distortion that causes or damages.
Preferably, described sleeve and described screw rod pass through threaded engagement.
Preferably, described screw rod upper end and/or described sleeve upper end are two-stage staged.
Preferably, described screw rod is outer-hexagonal screw rod or interior hexagonal screw rod.
The beneficial effects of the utility model:
(1) cylinder cap or interim tapping need not be torn open, save time;
(2) constantly rotary screw can extract fuel injector sleeve, easy and simple to handle;
(3), during mounting or dismounting, can not chip etc. be produced, not affect parts cleannes;
(4), during mounting or dismounting, ensure that the pass keyhole of crucial plane bottom mounting hole of oil sprayer and lower end is not impaired;
(5) uncertainty that the manual operation can evaded brings reduces to minimum, to ensure the uniformity installing and removing fuel injector sleeve;
After dismantling device is used to complete, screw rod and sleeve are assembled together, facilitate the arrangement of instrument, maintain the clean and tidy of instrument simultaneously.
