Abstract
The invention relates to the field of engines, in particular to a diesel engine fuel injector installation hole cleaning device, which comprises a sleeve which is matched with a fuel injector installation hole. An operating lever which is connected with a hairbrush is arranged in the sleeve. The hairbrush is arranged at one end part of the sleeve. The operating lever extends to the outside of the sleeve from the other end of the sleeve. The operating lever which is connected with the hairbrush and the sleeve are in retractable fit with each other. The fuel injector installation hole can be cleaned through the hairbrush and the cleaning device is very convenient to use; and by arranging the sleeve, an effect of protecting the inner wall of the fuel injector installation hole is taken. Moreover, since the cleaning device consists of three components, i.e. the sleeve, the hairbrush and the operating lever, the cleaning device is convenient to disassemble and replace and the cost is reduced.
Description
Technical field
The present invention relates to engine art, particularly a kind of diesel injector mounting hole washing unit.
Background technique
Diesel engine sometimes needs repeatedly to change oil sprayer and does comparative trial in the process of pilot development, inevitably produces a lot of oil stains in the process of the test in mounting hole of oil sprayer, and this just need to clean mounting hole of oil sprayer.
Summary of the invention
The object of the present invention is to provide a kind of diesel injector mounting hole washing unit, make things convenient for the cleaning of mounting hole of oil sprayer.
For reaching above effect, the technical solution used in the present invention is: a kind of diesel injector mounting hole washing unit, comprise a sleeve adaptive with mounting hole of oil sprayer, the operating stem that is connected with hairbrush places in the sleeve, hairbrush is positioned at an end of sleeve, operating stem is postponed to sleeve from the other end of sleeve, and the operating stem that is connected with hairbrush consists of telescopic the cooperation with sleeve.
Compared with prior art, there is following technique effect in the present invention:
This washing unit can clean mounting hole of oil sprayer by hairbrush, and very easy to use, the setting of sleeve plays a protective role to the mounting hole of oil sprayer inwall.This washing unit is by sleeve, hairbrush, three module compositions of operating stem simultaneously, and replacing for convenience detach reduces cost.

Fig. 2 is the perspective view of operating stem of the present invention;
Fig. 3 is the perspective view of sleeve of the present invention;
Fig. 4 is the vertical structural representation of hairbrush of the present invention.
Embodiment
Below in conjunction with Fig. 1 to Fig. 4 the present invention is described in further detail:
Consult Fig. 1-3, a kind of diesel injector mounting hole washing unit, comprise a sleeve 10 adaptive with mounting hole of oil sprayer, the operating stem 30 that is connected with hairbrush 20 places in the sleeve 10, hairbrush 20 is positioned at an end of sleeve 10, and operating stem 30 extends to outside the sleeve 10 from the other end of sleeve 10, and the described operating stem 30 that is connected with hairbrush 20 consists of telescopic the cooperation with sleeve 10.Rod end away from the operating stem 30 of hairbrush 20 is provided with the handle 31 of being convenient to grip, and is convenient to rotary manipulation bar 30.Described sleeve 10 arranges sprue 11 for the end that operating stem 30 passes through, offer through hole 111 on the sprue 11, the aperture of through hole 111 is less than the internal diameter of sleeve 10, through hole 111 coincide with the hole core of sleeve 10, the aperture of through hole 111 and operating stem 30 bars directly coincide, the setting of sprue 11, the motion of the axial direction of sleeve 10 swings and be unlikely so that operating stem 30 can only be postponed.The quality of sleeve 10 can be lighter, also saves material and processing cost, and operating stem 30 can for being slidingly matched, also can be screw-thread fit with through hole 111.In the present embodiment, described through hole 111 is tapped hole, one section of matching with through hole 111 of described operating stem 30 is provided with screw thread 32, and such setting is so that operating stem 30 can at the uniform velocity advance along the axial direction of sleeve 10 in the process of rotation, and cleaning performance is more even.
Consult Fig. 4, described hairbrush 20 comprises brush holder 21 and is fixed on bristle 22 on the brush holder 21 that brush holder 21 is connected with an end of operating stem 30.Brush holder 21 can have various shape, as long as guarantee brush holder 21 when operating stem 30 rotation, the zone that bristle 22 was brushed can cover the position that mounting hole of oil sprayer need to clean and get final product.Comparatively desirable hairbrush 20 is constructed as follows: described brush holder 21 is for cylindrical, the external diameter of brush holder 20 is consistent with the internal diameter of sleeve 10, can avoid so any swing of hairbrush 20, described bristle 22 is finer wire, one end root is put on the column end face of brush holder 21, the other end is the shape that overhangs, and bristle 22 is parallel to the shaft core line of brush holder 21.Brush holder 21 can be fixedly connected with operating stem 30, but the replacing for Convenient brush 20, in the present embodiment, the preferred screw-thread fit of using, arrange with brush holder 21 that the central position is provided with tapped hole 211 on the relative other end of the column end face of bristle 22, the bar of the aperture of described tapped hole 211 and operating stem 30 directly coincide, and the rod end that operating stem 30 links to each other with brush holder 21 is provided with the thread section 33 that matches with tapped hole 211.
When using the present invention that the diesel injector mounting hole is cleaned, sleeve is placed in the diesel injector mounting hole, the handle 31 of rotary manipulation bar 30, the hairbrush 20 that is attached thereto also can and then rotate, because operating stem 30 passes through screw-thread fit with the step hole 11 of sleeve 10 ends, operating stem 30 also can be along the axial motion of sleeve 10 in rotary course, can stretch out gradually sleeve 10 with the bristle 22 of electric brush 20, bristle 22 is to be made by steel wire, in its rotary course, can be to cleaning at the bottom of the oil injector hole.Along with being further rotated of handle 31, the position that bristle 22 stretches out is more and more, and the sidewall of bottom, mounting hole of oil sprayer hole is also had certain cleaning action.After rotating to maximum position, counterrotating handle 31 can carry out secondary cleaning to mounting hole of oil sprayer like this, and so repeatable operation just can accomplish to clean thoroughly to mounting hole of oil sprayer several times.Can use silk cloth or other materials that mounting hole of oil sprayer is carried out wiping after cleaning, like this can be so that cleaning performance be better.
