Abstract
This invention discloses one diesel spray fix and clamp device, which comprises spray device, spray clamper, tightening bolt, wherein, the spray and clamper end adopt sphere connection; the spray clamper outline is of Y shape with bow shape section; the spray clamper and cylinder cover, pad, clamper bolt hole adopt sphere surface to further reduce spray radium jump.
Description
Technical field
The present invention relates to a kind of dynamic power machine fastening clamper for fuel-injection device, relate in particular to a kind of fastening clamper for fuel-injection device of diesel engine.
Background technique
At present, conventional diesel engine oil sprayer means of fixation roughly has two kinds: a kind of is to fix with thread type, is about to the direct screw thread of diesel injector and is tightened in diesel engine cylinder cover, and another kind is that the clip two ends screw thread with the plane is pressed in diesel engine cylinder cover and fixes.Because pressure of explosion is bigger in the work under bad environment of diesel engine, cylinder, oil sprayer can bear certain compression shock, compression shock repeatedly like this, can cause the oil sprayer clip moving radially,, will cause the radial-play of oil sprayer clip through certain hour.Traditional diesel injector means of fixation then can't be avoided this play, thereby causes that jet quality descends, burning variation, deterioration of emission.
Summary of the invention
The present invention is for solving this technical problem of radial-play of oil sprayer clip, a kind of fastening clamper for fuel-injection device of diesel engine is provided, this fastening clamper for fuel-injection device of diesel engine, the radial-play that not only has the oil sprayer clip is little, and has connection reliably, characteristic of simple structure.
The technical solution adopted for the present invention to solve the technical problems is, a kind of fastening clamper for fuel-injection device of diesel engine comprises the oil sprayer that inserts in the cylinder cap, oil sprayer clip, the oil sprayer clip is anchored on clamping bolt on the cylinder cap; There are symmetrically arranged 2 to compress breach on the oil sprayer; In being characterised in that: compress breach and the oil sprayer clip of oil sprayer compress end and adopt sphere to compress to connect, and oil sprayer clip profile is the Y font, and the cross section is arc.
For the radial-play that makes the oil sprayer clip further reduces, described oil sprayer clip and cylinder cap compress end and also adopt sphere to compress to connect.
Reduce to minimum for the radial-play that makes the oil sprayer clip, be lined with packing ring on the described clamping bolt, packing ring compresses with bolt hole place employing sphere on the oil sprayer clip and connects.
Good effect of the present invention is, owing to compressing the spherical support that adopt the connection place, making oil sprayer form a lever supports, when oil sprayer forms the radial-play of trace, because spherical motion and lever principle effect, this lever supports this play that can effectively compensate oil sprayer, has avoided the wearing and tearing of oil sprayer, simultaneously the position of fuel injector nozzle can be guaranteed accurately.This means of fixation is for the high pressure co-rail system of current main-stream, and its advantage is particularly evident, is summarized as follows:
1, the axial float of oil sprayer can carry out the efficient adaptive compensation, guarantees that effectively diesel injector is not frayed;
2, simple in structure, easy accessibility is suitable for enforcement;
3, the oil sprayer that is fit to various diesel engines is fixed, the higher diesel engine of jet pressure and pressure of explosion especially, and cost is low.
Description of drawings
The present invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is that the present invention analyses and observe organigram.
Fig. 2 is the left view of Fig. 1.
Among the figure: 1. cylinder cap; 2. oil sprayer; 3. spherical washer; 4. clamping bolt; 5. oil sprayer clip.
Embodiment
In the embodiment shown in Fig. 1,2, a kind of fastening clamper for fuel-injection device of diesel engine comprises the oil sprayer 2 that inserts in the cylinder cap 1, oil sprayer clip 5, oil sprayer clip 5 is anchored on clamping bolt 4 on the cylinder cap 1; There are symmetrically arranged 2 to compress breach on the oil sprayer 2; Compress breach and the oil sprayer clip 5 of oil sprayer 2 compress end and adopt sphere to compress to connect, and oil sprayer clip 5 profiles are the Y font, and the cross section is arc.
For the radial-play that makes the oil sprayer clip further reduces, oil sprayer clip 5 and cylinder cap 1 compress end and adopt sphere to compress to connect.
Reduce to minimum for the radial-play that makes the oil sprayer clip, be lined with packing ring 3 on the clamping bolt 4, packing ring 3 compresses with bolt hole place employing sphere on the oil sprayer clip 5 and connects.
Carry out oil sprayer when fastening with this covering device, earlier oil sprayer 2 press in the shown position insertion cylinder cap 1.Then the Y shape of oil sprayer clip 5 end is inserted, compress oil sprayer 2 with two ends, oil sprayer clip 5 compresses end with the location of the sphere processing groove on the cylinder cap with cylinder cap 1, places spherical washer 3 again, tightens clamping bolt 4, and moment is tightened and both can in accordance with regulations.
