The oil filling operation can be implemented for a machinery device without the manual intervention when working, and thereby the utility model has the high work efficiency and saves labor and time.
Description
Technical field
The utility model belongs to the device, particularly oil gun that injects lubricant oil to machinery.
Background technique
Be the oiling chamber in the existing oil gun housing, be equipped with in the main oil pocket and press oily piston, handle is equipped with on the piston rod top, housing bottom is equipped with a foot-propelled oil pump that is communicated with the oiling chamber, during oiling, need ceaselessly use both hands and feet and the lubricant oil in the housing could be injected in the mechanical device, working efficiency is lower, waste time and energy, this when injecting the higher machine oil of ratio of viscosities for mechanical device, effort especially.
Summary of the invention
The purpose of this utility model is to provide a kind of oil gun, does not need manual intervention to carry out oiling work to mechanical device during work, and high working efficiency is time saving and energy saving.
The purpose of this utility model is achieved in that a kind of oil gun, comprise the housing that top cover is housed, housing bottom center and top cover center thereof all are being provided with through hole, piston is housed in the housing, piston rod is equipped with at the piston center, stuffing box bearing all is being set in the described through hole, uniform screw thread on the outer surface of piston rod, the piston center is being provided with tapped through hole, piston rod passes from tapped through hole and is threaded with piston formation, the piston rod upper end is by the stuffing box bearing location that is positioned at the top cover through hole, pass the stuffing box bearing axis hole of its lower end in the through hole of housing bottom surface, the high pressure oil pump that is communicated with in motor and one and the housing is installed respectively on the outer wall of housing, on its oil outlet oil filler pipe is housed, the high pressure oil pump rotating shaft, piston rod and motor rotary shaft three lower end are equipped with the gear that meshes together successively respectively.
In the time of need be for the mechanical device oiling, connect motor power and make its rotation, motor is by gear drive piston rod successively and high pressure oil pump rotation, piston rod drives piston decline the lubricated wet goods oils in the housing is exerted pressure in rotation, because high pressure oil pump is communicated with housing is interior, the pressure oil in the housing just injects in the mechanical device continuously by high pressure oil pump, does not need manual intervention to carry out oiling work to mechanical device during work, high working efficiency, time saving and energy saving.The utility model is simple in structure, and is easy to manufacture, is easy to promote.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 looks cross-sectional view for master of the present utility model;
Fig. 2 is a plan view of the present utility model.
Embodiment
A kind of oil gun as shown in Figure 1 and Figure 2, comprises the housing 1 that top cover 3 is housed, and housing 1 is cylindrical tube shape or is the cylindroid tubular.Housing 1 bottom center and top cover 3 centers thereof all are being provided with through hole, piston 11 is housed in the housing 1, piston rod 2 is equipped with at piston 11 centers, the sealing oil keeper all is being set in the described through hole, the stuffing box bearing that peace is changeed in top cover 3 through holes is a rolling ball bearing, and the stuffing box bearing that is installed in the housing 1 bottom surface through hole is cylindrical roller thrust bearing or tapered roller bearing.Uniform screw thread on the outer surface of piston rod 2, described screw thread are square threaded form or are V-thread.Piston 11 centers are being provided with tapped through hole, piston rod 2 passes from tapped through hole and is threaded with piston 11 formation, piston rod 2 upper ends are by the stuffing box bearing location that is positioned at top cover 3 through holes, pass the stuffing box bearing axis hole of its lower end in housing 1 bottom surface through hole, the high pressure oil pump 8 that is communicated with in motor 4 and one and the housing is installed respectively on the outer wall of housing 1, oil filler pipe 9 is housed on its oil outlet.As shown in Figure 1,, an one-way valve 10 is installed on the oil outlet of high pressure oil pump 8, is connecting oil filler pipe 9 on the oil outlet of one-way valve 10 in order to prevent the oily water conservancy diversion in the oil filler pipe 9.High pressure oil pump rotating shaft, piston rod 2 and motor rotary shaft three lower end are equipped with the gear that meshes together successively respectively, and driven gear 7 is equipped with in piston rod 2 lower ends, and driving gear 5 is equipped with in the motor rotary shaft lower end.
As shown in Figure 1, stop when contacting descending and cause the vexed commentaries on classics of motor in order to prevent that piston 11 from dropping to the housing bottom surface, limitation travel switch 6 also is being set on the housing bottom surface, limitation travel switch 6 is electrically connected with motor 4, like this when piston 11 drops near the housing bottom surface, at first touch limitation travel switch 6, the power supply that can cut off motor 4 immediately makes its stall.
