Abstract
The utility model discloses an oiling machine for a rock drilling machine, belonging to parts of rock drilling machine and comprising a spindle, a shell and an oiling valve. A valve seat is arranged at one end of the spindle, and an airflow channel passes through the center of the spindle. The shell surrounds the outer side of the spindle and is connected with the spindle in a sealing manner to form an oiling cavity, and the oiling cavity is respectively communicated with the valve seat and the airflow channel through two air holes. The oiling valve is sleeved in the valve seat; a durable sleeve is arranged between the oiling valve and the valve seat; and the durable sleeve is embedded in the valve seat. The utility model solves the problem that the prior oiling machine of the rock drilling machine can not be completely stopped, is easy to leak oil and has overlarge weight and short service life. The utility model is reasonably structured and is widely applied to the rock drilling machine.
Description
Technical field
The utility model relates to a kind of accessory of rock drill, relates in particular to a kind of oil gun that is used for rock drill.
Background technique
When using rock drill to carry out bore operation, rock drill inner body high-speed motion requires each moving parts to remain sufficient lubrication, and therefore, the oil gun of outfit has automatic oiling, satisfies the lubricated requirement of machine.Before the start, with correct safe being connected of rock drill and oil gun, during connection, end by the oiling body is threaded with the rock drill gas-pipe bend, pipeline is connected and the other end of oiling body and air compressor are calmed the anger, guarantee when rock drill is worked, calm the anger and enter oil gun housing inner chamber by oiling body inlet hole, exert pressure to pasta, make lubricant oil enter the fuel-displaced duct of fuel feeding valve from the oil outlet of oiling body, and the fuel-displaced duct on the fuel tap and pressure gas stream are to vertical, so under the swiftly flowing condition of calming the anger, form pressure reduction at oil outlet road junction place, make lubricant oil spray into the oiling body calm the anger form in the duct vaporific, enter rock drill and air leg in company with calming the anger, lubricated each moving parts.Because fuel feeding valve rotates in regulator hole when regulating oil mass back and forth, makes and fuel feeding valve and mandrel wear causes poor sealing, causes oil leak easily, influences the working life of oil gun.
The model utility content
Technical problem to be solved in the utility model is: a kind of oil gun that is used for rock drill is provided, closes not dead, leakage of oil easily to solve the rock drill oil gun, weight is excessive, the technical problem that working life is short.
For solving the problems of the technologies described above, the technical solution of the utility model is: be used for the oil gun of rock drill, comprise mandrel, described mandrel one end is provided with valve seat, and the center of described mandrel is run through and is provided with air-flow path; Housing, described housing are surrounded on the described mandrel outside and are connected to form the oiling chamber with described stem seal, and described oiling chamber is communicated with valve seat and air-flow path respectively by two pores; Fuel feeding valve, described fuel feeding valve are set in the described valve seat; Be provided with wear-resistant sleeve between described fuel feeding valve and the valve seat, described wear-resistant sleeve is flush-mounted in the described valve seat.
As a kind of improvement, it is the plastics mandrel that engineering plastics are made that described mandrel adopts material.
As further improvement, it is the nylon mandrel that nylon is made that described mandrel adopts material.
As a kind of improvement, described wear-resistant sleeve is a copper sheathing.
Owing to adopted technique scheme; the beneficial effects of the utility model are: owing to be embedded with the wear body that copper sheathing is made in the valve seat of oil gun; make when fuel feeding valve rotates; do not contact with the valve seat of mandrel; not enough each other one-tenth friction; protected oil gun mandrel and fuel feeding valve, prolonged the working life of oil gun and effectively prevented leakage of oil.
Because the oil gun mandrel adopts nylon material to make, and has replaced traditional steel part, makes oil gun weight lighten, frangibility not, and have excellent sealing performance, and be not easy fragmentation, further prolonged the working life of oil gun.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's a structural representation;
Among the figure: 1, copper sheathing, 2, fuel feeding valve, 3, housing, 4, mandrel, 5 oil are stifled, and 6, valve seat, 7, the oiling chamber, 8, air-flow path.
Embodiment
As shown in drawings, a kind of oil gun that is used for rock drill, comprise mandrel 4, housing 3, fuel feeding valve 2 and oil stifled 5, the oil gun housing of being made by transparent engineering plastics 3 is around the middle part of mandrel 4, and be tightly connected with mandrel 4, the cavity between housing 3 and the mandrel 4 is oiling chamber 7, an end of mandrel 4 is provided with valve seat 6, be set with the fuel feeding valve 2 that is used to control oil mass in the valve seat 6, the center of mandrel 4 is run through and is provided with air-flow path 8; Oiling chamber 7 is communicated with valve seat 6 and air-flow path 8 respectively by two pores; Be provided with copper sheathing 1 between fuel feeding valve 2 and the valve seat 6, described copper sheathing 1 is flush-mounted in the valve seat 6, has avoided direct friction between fuel feeding valve 2 and the valve seat 6 and produces the phenomenon of oil leak, has improved the wear-resisting property of oil gun, has prolonged the working life of oil gun.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
