Abstract
The utility model discloses a kind of spark plug assembly tool, it comprises tightens bar, described bar one end of tightening offers and tightens joint, describedly tighten in joint the magnet be provided with by the second spring swelling, described bar of tightening is provided with pad and back-up ring at it successively away from the end of tightening joint, described in tighten bar and be provided with the end of tightening joint at it and be provided with boss, described boss is provided with sheath, between described back-up ring and boss, be provided with the first spring, and described sheath is by the first spring swelling.The beneficial effects of the utility model are: the utility model not only can protect spark plug can not drop in the process of installing, and can prevent the quality problems because negligence of operation causes simultaneously; The utility model plays the effect of protection spark plug when installing spark plug, avoid because operate miss causes damage to spark plug.
Description
Technical field
The utility model belongs to engine production technical field of tools, is specifically related to a kind of spark plug assembly tool.
Background technology
Spark plug, as the end fitting of engine igniting system, plays vital effect to engine, and forming spark plug major part is insulator, housing, wiring screw rod and electrode.Sparking-plug electrode comprises central electrode and lateral electrode, is spark gap between the two.The size in gap directly affects the startup of engine, power, job stability and economy.
During spark plug assembling, the sleeve of an interior hexagonal is often utilized to entangle spark plug front portion, outer-hexagonal in the middle part of interior hexagonal and spark plug coincide, sleeve rear end can connect rotary part, and sleeve is at artificial or driven by motor backspin then utilize the screw thread on metal shell to be connected on cylinder block by spark-plug thread.
Existing instrument, when engine is produced in batches, is just necessary the electrode protecting spark plug in the process of assembling spark plug, avoids hitting because of misoperation on other parts, change spark plug gap thus cause engine ignition fault.
Utility model content
The utility model overcomes in prior art and easily causes spark plug to hit on other parts when assembling because of misoperation; change spark plug gap thus cause engine ignition fault; there is provided a kind of spark plug of not only can protecting can not drop in the process of installing, the spark plug assembly tool of the quality problems caused because of negligence of operation can be prevented simultaneously.
For achieving the above object, the utility model is by the following technical solutions:
A kind of spark plug assembly tool, it comprises tightens bar, described bar one end of tightening offers and tightens joint, describedly tighten in joint the magnet be provided with by the second spring swelling, described bar of tightening is provided with pad and back-up ring at it successively away from the end of tightening joint, described in tighten bar and be provided with the end of tightening joint at it and be provided with boss, described boss is provided with sheath, between described back-up ring and boss, be provided with the first spring, and described sheath is by the first spring swelling.
In the technical program, spark plug sheath in the process of tightening can tighten the motion of bar axial direction; the protective effect to spark plug is played when spark plug is installed by the movement of sheath; thus avoid the damage that maloperation causes spark plug; by tightening in joint the magnet increased by the second spring swelling; adsorbed when assembling spark plug by magnet; spark plug not only can be protected can not to drop in the process of installing, the quality problems because negligence of operation causes can be prevented simultaneously.
Further technical scheme is, described in tighten on bar outer wall and offer cannelure, described pad and back-up ring are installed in cannelure successively.
By being provided with cannelure tightening on bar outer wall in the technical program, pad and back-up ring are installed in cannelure, by pad and back-up ring for stopping the first spring.
Further technical scheme is, the size of described sheath cross section is mated mutually with the size of spark plug cross section.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model not only can protect spark plug can not drop in the process of installing, and can prevent the quality problems because negligence of operation causes simultaneously;
2, play the effect of protection spark plug when the utility model installs spark plug, avoid because operate miss causes damage to spark plug.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
As shown in Figure 1, the Reference numeral name of its correspondence is called:
1 tightens bar, 2 first springs, 3 sheaths, 4 magnet, 5 second springs, 6 back-up rings, 7 pads.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of spark plug assembly tool, it comprises tightens bar 1, described bar 1 one end of tightening offers and tightens joint, describedly tighten in joint the magnet 4 be provided with by the second spring 5 tensioner, described bar 1 of tightening is provided with pad 7 and back-up ring 6 at it successively away from the end of tightening joint, described bar 1 of tightening is provided with the end of tightening joint at it and is provided with boss, described boss is provided with sheath 3, the first spring 2 is provided with between described back-up ring 6 and boss, and described sheath 3 is by the first spring 2 tensioner, described tightening on bar 1 outer wall offers cannelure, described pad 7 and back-up ring 6 are installed in cannelure successively, the size of described sheath 3 cross section is mated mutually with the size of spark plug cross section.
Use procedure of the present utility model is as follows:
Spark plug is positioned over and tightens in bar 1 sleeve, the magnet 4 inlayed in sleeve is utilized to be held by spark plug, prevent spark plug from dropping, when again spark plug being put into cylinder cap spark plug mounting hole, spark-plug thread and electrode part can cover by sheath 3, prevent in the process put into because operate miss damages sparking-plug electrode, thus reduce quality risk.
Above detailed description of the invention is described in detail to essence of the present utility model; but can not limit protection domain of the present utility model; apparently; under enlightenment of the present utility model; the art those of ordinary skill can also carry out many improvement and modification; it should be noted that these improve and modify all to drop within claims of the present utility model.
