Abstract

The invention provides an oil filling device, which relates to new oil ejector field. The lubricating device in rock drilling project is sensitive to the adhesive of oil and is not beneficial to the excellent lubrication and the state that the oil adjustor is jammed and can not supply oil normally, the shell is supported by one end, and thus the intensity is low. The invention uses oil adjusting blade aperture design, solves the problem that the oil adjustor is sensitive to the oil, and the oil quantity is not stable, and the invention has a new designed filter mechanism, and it also increase the elastic localization mechanism to make the oil quantity stable, it uses shell structure whose two ends are half sealed, so the intensity is upgraded greatly.

Description

Oil gun

Technical field

The present invention relates to a kind of novel oil gun field, lubricating in using at rock drill.

Background technique

Because the work of rock drill is a kind of violent impact and rotatablely moves and work in dust atmosphere.Guarantee the normal operation of rock drill, to its lubricating requirement should be accurate, reliable and stable be crucial.

The previous open defect of the oil supplying device in rock drill uses: 1, housing is that an end is semiclosed, and the other end is uncovered structure, and intensity is low easily breaks for itself.2, after fuel-flow control was finished, the regulating handle position changed in violent operational vibration, and not fuel feeding or oil mass very ambassador's rock drill in use and unstable disposed upright damage.3, the valve core used of its oil supplying device is the disc change, and surface of contact changes responsive and instability that produce to oil viscosity greatly in the cooperation.4, present oiling do not have oil filter might be in using and refueling dirt enter and stop up valve core in the oil pocket and can not cause rock drill because of the overheated damage parts of oil starvation by fuel feeding.

Summary of the invention

The present invention be directed to four kinds of shortcomings of above oiling purpose and carried out significant improvement, 1, the cutting edge design that puts in fuel-flow control realizes accurately regulating oil mass, and is insensitive to oil viscosity.2, to have adopted two ends be semi-enclosed cylindrical structure to the oil gun housing, thereby improved working strength greatly.3, increased the oil strain structure, made degree of wear reduction in the rock drill work, reliable operation.4, increased novel positioning design, made it judder at work, exchange oil mass do not change and regulate very convenient accurately.

Description of drawings

Accompanying drawing is a sectional view of the present invention.

1 transfer that oily core bar weld assembly, 2 control sleeves, 3 pads, 4 filter screens, 5 housings, 6 oil block up among the figure, 7 snap rings, 8 cushion rubbers, 9 steel traveler, 10 cushion rubbers, 11 cushion rubbers, 12 cushion rubbers, 13 cushion rubbers, 14 oil outlet tubes, 15 springs, 16 steel balls, 17 cushion rubbers.

Embodiment

Make as a detailed description of the present invention below in conjunction with accompanying drawing.

Because parts such as housing 5 and the oily core bar weld assembly 1 of accent and cushion rubber and snap ring form the cavity volumes of sealing fully, by the stifled 6 filling lubricant oil of oil, the center hole of pressurized air through transferring oily core bar weld assembly 1 passes through at a high speed in the use of rock drill, through transferring the aperture e qi of chong channel ascending adversely in Seal cage on the oily core bar, because pressure increases, the fluid in the Seal cage entered oil outlet tube 14 through hole a. filter screen 4 hole b. and hole c. through control sleeve 2 and adjusting spacer ring between the oily core bar 1 of accent and entered rock drill with pressurized air and form lubricated this moment, the big I of lubricant oil oil mass realizes by rotating control sleeve 2, and quantitatively final.

Claims (5)

1. oil gun, by transferring oily core bar weld assembly (1), control sleeve (2), housing (5), oil outlet tube (14), the stifled parts such as (6) of oil is formed, it is characterized in that, radial hole a on the housing (5) groove top with transferring oily core bar weld assembly (1) communicates, again and transfer b hole on the oily core bar weld assembly (1) to communicate and the c hole conical surface (1: 3) that forms between the Φ 38-0.05 and 39 on transfer oily core bar weld assembly (1) the spacer ring of formation between two assemblies that moves axially that communicates along with control sleeve (2), this gap ring can be zero or open greater than 2 millimeters or more, and between spring (15) and steel ball (16) and the control sleeve (2) and elasticity location.

2. oil gun according to claim 1 is characterized in that, transfers between 1: 3 conical surface on the oily core bar weld assembly (1) and the oil mass adjustment cover (2) fitting surface d along with the spacer ring that moves axially formation (can be 0-2mm) of control sleeve (2).

3. oil gun according to claim 1 is characterized in that, its housing of described oil gun (5) is that a kind of two ends are semi-enclosed cartridge type.

4. according to claim 1 and 2 described oil guns, it is characterized in that, entering oil outlet tube (14) by the ring-like gap between hole b and hole c and oil rod weld assembly (1) and the control sleeve (2) (and step gaps are spent on the plane of distortion or 90) because radial hole a above the housing (5) and the filter screen (4) above the oily core bar weld assembly of accent (1) filter the back to lubricant oil.

5. oil gun according to claim 1 is characterized in that, by the cooperation of spring (15) with the relative control sleeve of steel ball (16) (2), and rotation feel that forms and accurate gear location.
