Description
Technical field
The present invention relates to the technical field of oil feeder for lubricating, relate in particular to a kind of oil feeder for lubricating that uses at pneumatic tools such as wind big guns.
Background technique
In order to guarantee the normal operation of wind big gun or rock drill, oil feeder is indispensable parts, to the safe handling of wind big gun, reduce wear, increase working life, raise the efficiency bigger influence.Along with the continuous development of industry, also more and more higher to the requirement of all oil feeder for lubricating.
Have following several at present the lubricating system of wind big gun: 1., directly to add butter for the wind big gun, its deficiency is, butter is easy to adhere to impurity, so must regularly open protecgulum, the remaining butter on protecgulum and the impact frame is cleaned up, be coated with and spread suitable butter, lock protecgulum again, then low speed start is 20～30 seconds, so operation is cumbersome, the T/A that need add butter can't measure, and therefore can not reach best fuel feeding state; 2., connecting oil sprayer on the pipeline of high pressure air, its deficiency is, parts such as pipe coupling have been increased, need go to observe the memory space of lubricant oil during use to the pipeline place, adjust fuel delivery and volume read-out etc., the use amount of control lubricant oil that can't be correct, so that cause excessive use lubricant oil and increase user cost, or very few fuel feeding and cause wind big gun insufficient lubrication until damage.
It is that the Chinese invention patent application " oil gun " of ZL200410077904.0 (notification number is CN1587781Y) discloses a kind of such structure that one patent No. is arranged, a kind of oil gun, by transferring oily core bar weld assembly, control sleeve, housing, oil outlet tube, the stifled part that waits of oil is formed, it is characterized in that, radial hole a on the housing communicates with groove above transferring oily core bar weld assembly, again and transfer b hole on the oily core bar weld assembly to communicate and the c hole communicates the conical surface that forms between the Ф 38-0.05 and 39 on transfer oily core bar weld assembly along with moving axially of control sleeve forms a spacer ring between two assemblies, this gap ring can be zero or open greater than 2 millimeters or more, and between spring and steel ball and the control sleeve and elasticity location.This oil gun in use pressurized air through aperture e qi of chong channel ascending adversely in Seal cage, enter in the cutter machine with pressurized air so that the adjusting spacer ring of the fluid in the Seal cage between hole a, opening of sieve and control sleeve and accent oil core bar entered oil outlet tube, the atomizing effect of this oil gun lubricant oil is poor, so its insufficient lubrication, and this oil gun also is not suitable for being applied on the wind big gun lubricated.
Summary of the invention
Technical problem to be solved by this invention is the oil feeder for lubricating that provides a kind of lubrication effect and lubricants capacity to regulate at above-mentioned prior art present situation, and this oil feeder for lubricating is particularly suitable for using on the wind big gun.
Second technical problem to be solved by this invention provides a kind of oil feeder for lubricating that can accurately read lubricants capacity, to reach the purpose that accurately adjusts oil mass.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of oil feeder for lubricating, include the joint of hollow, the shoe cream room that links to each other with joint, it is characterized in that being equipped with a flow control valve on the described shoe cream room roof, valve body is exposed on the spool top of flow control valve, and be fixed with an adjusting nut on spool top, liquid sealing between the valve body of flow control valve and the shoe cream room roof, the filler opening filler opening and the shoe cream room of flow control valve communicate, and the oil outlet of flow control valve then communicates with the inner chamber of joint by transport pipe.
In order accurately to read the oil feeder for lubricating of lubricants capacity, vibration when preventing the work of wind big gun, the change in location that causes spool, to reach the purpose that accurately adjusts oil mass, the valve body upper-end surface of above-mentioned flow control valve is provided with one and is carved with the index plate that can demonstrate fuel delivery numerical value on it, is fixed with the pointer that points to index plate fuel delivery numerical value on the described adjusting nut.
In order to prevent this oil feeder in the course of the work, cause the spool skew of flow control valve owing to vibration, and the accuracy of influence metering, the tightening nut that on the spool of the roof that exposes shoe cream room, has been threaded, this tightening nut is between adjusting nut and valve body upper-end surface.
Refuel to shoe cream room for convenience, have oil hole on the roof of above-mentioned shoe cream room, oil hole is provided with a plug screw that oil hole can be blocked.
Above-mentioned shoe cream room by be arranged on joint top and ringwise retaining wall, end cap, the ringwise lubricating cup of both ends open is formed; Wherein retaining wall forms the roof of shoe cream room; Described end cap is threaded in the below of joint and forms the bottom surface of shoe cream room; It is outside and form the sidewall of shoe cream room that described lubricating cup is set in joint between retaining wall and the end cap, and lubricating cup inner circle wall and joint periphery wall have spacing and form oil storage space, liquid sealing between the upper end of lubricating cup and the retaining wall, liquid sealing between lubricating cup lower end and the end cap; Described transport pipe is positioned at shoe cream room.The structure of above-mentioned shoe cream room can make shoe cream room establish along the side face ring of joint, can simplify the structure of whole oil feeder like this, make its beautiful shape, and it makes things convenient for also us to assemble this oil feeder.
The structure that above-mentioned transport pipe is connected oil outlet on the flow control valve is: described oil outlet is a tapped hole, a connection block has been threaded on oil outlet, connection block has the penetration hole that communicates with flow control valve on the middle part, a connector cover also has been threaded in the outside of connection block, being provided with seal ring between connector cover and the flow control valve seals, between connector cover and connection block, be provided with pad, described transport pipe enters in the penetration hole of connection block after passing connector cover, pad, and pad and transport pipe weld together.The structure that above-mentioned transport pipe is connected on the joint is: have one and the tapped through hole that communicates of joint inner chamber on the described joint, a connection block has been threaded on the tapped through hole, connection block has the hole that communicates with the joint inner chamber on the middle part, a connector cover also has been threaded in the outside of connection block, being provided with seal ring between connector cover and the joint seals, between connector cover and connection block, be provided with pad, described transport pipe enters in the hole of connection block after passing connector cover, pad, and pad and transport pipe weld together.The Placement of above-mentioned transport pipe and flow control valve and joint, its liquid sealing is relatively good, also can adopt other existing various Placements certainly, as long as satisfy the direct sealing of transport pipe and joint and flow control valve.
