Description
Technical field
The utility model relates to the automatic oiling device of the oiling device, particularly a kind of pneumatic torque spanner of pneumatic torque spanner (being commonly called as wind bubble or pneumatic wrench).
Background technology
The oiling mode that existing pneumatic torque spanner all is artificial singles, it all is that sidepiece at the main frame handle is provided with the oil filler point that feeds in the main air intake usually, after the oiling, oil filler point is closed, the oil that injects in the main air intake is mixed with compressed air to be produced oil gas and enters that host work is indoor to carry out work, this device has the following disadvantages: (1) oiling technology is loaded down with trivial details, each screw of all wanting to unclamp with specific purpose tool earlier oil filler point, the ability oiling, treat that oiling finishes, also lock-screw once more; (2) less because of oil filler point, make when adding oiling very inconvenient; (3) because too frequent degree of tightness oiling screw damages screw hole easily, cause damage of components and leakage of oil; (4) owing to be artificial single oiling mode, therefore to very frequent oiling could guarantee normal the use, increase the time of operation; (5) injection flow is difficult to control, and oil has just injected in the main air intake, is promptly taken away by disposable basically with gas flow, can not use for a long time, causes waste to a certain extent.
The utility model content
In order to solve existing in prior technology the problems referred to above, the utility model provides a kind of automatic oiling device of pneumatic torque spanner, it not only can oiling in the trend main air intake when host work, thereby significantly reduce the oiling number of times, the trouble of avoiding frequent oiling to bring, save time, prolong the service life of oiling parts, guarantee working properly; And can control the injection flow of each oiling automatically, and when quitting work, main frame also can stop oiling automatically, therefore help economizing on oil.
Technical solutions of the utility model are to constitute like this, it comprises the oil filler point of being located at main frame handle one sidepiece, the inner port of this oil filler point main air intake interior with being located at the main frame handle is communicated with, and it is characterized in that: the angle α between the hole heart line of described oil filler point and the airintake direction of main air intake is less than 90 degree; The external port of oil filler point is provided with oiling observation ward, and the other side of main frame handle is provided with oil tank, is communicated with by oil-absorbing pipeline between oiling observation ward and the oil tank, and the inlet port of oil-absorbing pipeline is connected to the oil tank bottom; Be provided with the pressure balance air admission hole between described main air intake and the oil tank, this pressure balance air admission hole is perpendicular to the airintake direction of main air intake.
Operation principle of the present utility model is described as follows: when the air inlet switch open of main frame, and weighing apparatus air admission hole in the main air intake, and this pressure balance air admission hole is perpendicular to the airintake direction of main air intake, so air pressure in the oil tank and the interior air pressure balance of main air intake; And since the angle α between the airintake direction of the hole heart line of oil filler point and main air intake spend less than 90, therefore air or the oil in the compressed air drive oil filler point advances together, make and form negative pressure in the oil filler point, oil in the oil tank just sucks oiling observation ward from oil-absorbing pipeline under the effect of positive negative pressure, and then flows in the main air intake from oil filler point.The oil that enters main air intake mixes with compressed air and produces oil gas and enter that host work is indoor to carry out work.When main frame quits work,, can not make oil filler point form negative pressure, so this device stop oiling automatically owing to do not have compressed air to enter in the main air intake.By observation, can recognize at any time whether oil is arranged, and whether oil injects in the main air intake smoothly to oiling observation ward.
Than prior art, the utlity model has following remarkable advantage: (1) reduces frequent oiling machine fluid, makes to prolong more than the several times blanking time of oiling; (2) can oiling in the trend main air intake when host work, the state that makes main frame can always remain on oil uses down, thus the service life of having improved main frame greatly; (3) only just oiling when host work, when main frame quit work, this device also stopped oiling automatically, had therefore given full play to oily effect, had also saved to a certain extent with oil; (4) do not need frequent degree of tightness oiling screw, thus the service life of having improved the oiling parts greatly.
In order to guarantee that further the oil filler point place forms negative pressure, in the utility model technique scheme, described oil filler point is made of the oil fuel tube internal pipeline that is installed on the main frame handle, and the inner spout of oil fuel tube slightly stretches into main air intake slightly.Like this, stretch into main air intake oil fuel tube inner spout slightly and can play the partial occlusion effect, both avoided air to be blown in the oil filler point, the oil that makes things convenient for air driven to flow to the oil fuel tube inner spout again advances.
In order further to regulate the size of unit injection flow, the utility model further improvement in the technical proposal is: the oil regulator that also is provided with the channel sized that is used to regulate oil-absorbing pipeline on the described oil-absorbing pipeline.By oil regulator, the user can regulate the unit injection flow according to the actual operating position with oil of main frame, thereby both effectively improves the serviceability of main frame, and oil avoids waste again.
