Detailed description of the invention
Below in conjunction with accompanying drawing 1 to Fig. 2, this utility model automatically cleaning vacuum oil pump is further described.
A kind of automatically cleaning vacuum oil pump, including cylinder body 1, piston 2, piston rod 3, cam 4 and connection ring 5, piston 2 is arranged in cylinder body 1, and can slide relative to the inwall of cylinder body 1. Being connected by universal drive shaft 6 between piston 2 and piston rod 3, the other end of piston rod 3 connects also by universal drive shaft 6 and cam 4. Connecting ring 5 in circular, cam 4 is located in connection ring 5, and the nose 41 of cam 4 contacts with the inner surface connecting ring 5, and cam 4 is linked together by the output shaft of rotating shaft 7 and motor. Piston 2 sheathed one set 9 is installed, install and set 9 be additionally provided with the automatically cleaning assembly 8 for cylinder body 1 inwall is cleared up, and this automatically cleaning assembly 8 can also do reciprocation cycle motion together along with piston 2, its structure is as shown in Figure 1.
So when piston 2 does reciprocation cycle motion for a long time in cylinder body 1; cylinder body 1 inwall just can be cleared up by automatically cleaning assembly 8 along with the motion of piston 2; dispose along with oil enters in cylinder body 1 and is attached to the impurity on cylinder body 1 inwall timely; maintain the cleannes installing set 9 and cylinder body 1 inwall; avoid because impurity is mixed between installation set 9 and cylinder body 1 inwall; and make to install in the process overlapping 9 and cylinder body 1 inwall relative motion; friction aggravation, the quickening damaged, it is achieved thereby that to cylinder body 1 inwall and the protection installing set 9. That is by the setting of this automatically cleaning assembly 8, it is possible to well to cylinder body 1 inwall and installation set 9 offer protection, extend both service life.
It should be noted that, all it is connected by universal drive shaft 6 between piston 2 with piston rod 3, piston rod 3 and cam 4, it is because universal drive shaft 6 and there is multiple degrees of freedom, reduce the shear stress on piston rod 3 as much as possible, when such piston rod 3 drives piston 2 to move back and forth in cylinder body 1, just can seem very flexible, very convenient.
Furthermore it is also possible to arrange inlet valve 10 and air bleeding valve 11 on cylinder body 1, the inside and outside pressure of cylinder body 1 thus can be allowed timely to be balanced, maintain the piston 2 normal reciprocation cycle motion in cylinder body 1.
For automatically cleaning assembly 8, being given as optimal way, its structure is specific as follows herein:
Automatically cleaning assembly 8 includes mounting box 81, and mounting box 81 is fixed on installation set 9, is provided with hairbrush 82, spongy body 83, fixing plate 85 and fuel tank 84 in mounting box 81. Head 821 and cylinder body 1 inwall of hairbrush 82 are close together, the afterbody 822 of hairbrush 82 is then infiltrated in spongy body 83, spongy body 83 is fixed on fixing plate 85, several slit pores 851 offered by fixing plate 85, lubricating oil in fuel tank 84 just enters in spongy body 83 by these slit pores 851 after capillarity, realizing fuel feeding for hairbrush 82, its structure is as shown in Figure 2.
When such piston 2 does reciprocation cycle motion in cylinder body 1; set 9 is installed to be also carried out moving back and forth with whole mounting box 81; and then cylinder body 1 inwall constantly will be cleaned by the hairbrush 82 in mounting box 81 in motor process; the impurity being attached on cylinder body 1 inwall is cleaned out timely; realize cylinder body 1 inwall and the protection installing set 9; slow down the abrasion of both, extend both service life.
And constantly penetrate into the afterbody 822 of hairbrush 82, head 821 from spongy body 83 along with the lubricating oil in fuel tank 84, it it is then the cleaning further facilitating hairbrush 82 to cylinder body 1 inwall, lubricating oil can be attached to cylinder body 1 inwall simultaneously, the effect of a lubrication can also be played, the effective friction reduced between cylinder body 1 inwall and installation set 9, slows down the abrasion installing set 9 and cylinder body 1 inwall another aspect.
In above-described embodiment, preferably being secured in together by dismountable mode between mounting box 81 and installation set 9, dismountable mode can be common clamping, snapping etc., so arrange in order that facilitate the replacing of resistance to mounting box 81, after the wear extent of the hairbrush 82 in mounting box 81 reaches boundary value, or when the wear extent of hairbrush 82 is bigger, it is possible to easily realize the replacing of the dismounting of mounting box 81, hairbrush 82.
In addition, being arranged at of automatically cleaning assembly 8 symmetry can also be installed on the front and rear end overlapping 9, structure as shown in Figure 2, so can realize the cleaning to cylinder body 1 inwall from the rear and front end installing set 9 simultaneously, while improving the efficiency of cleaning, also further improve the cleanliness factor of cylinder body 1 inwall.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model. It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
