Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; Lubricating cup is embedded in valve piece 10 inside; Be provided with output end cap external cover 19 between lubricating cup and the valve piece, hexagonal plug 16 and 90 degree were provided with shift fork 15, plunger 17 and one-way valve 13 to wire connection 11 successively in valve piece 10 left and right sides were equipped with respectively between interior hexagonal plug 16 and 90 is spent wire connection 11; Shift fork 15 lays respectively at the lubricating cup left and right sides with plunger 17, and plunger 17 outsides are connected with piston spring 18 and plunger bushing 14 in turn; Lubricating cup right side hollow cavity is built-in with steel ball 12, and top, lubricating cup top is connected with lubricating cup pin 20; Piston rod 22 and outside fuel sucking pipe 8, piston 7 and the piston 7 that connects thereof and compress the spring 6 that is equipped with between the end cap 3 and all place in the hollow cavity that lucite tube inner bag 4 forms; Piston rod 22 is connected through O type circle fixture 21 with fuel sucking pipe 8; Fuel sucking pipe 8 bottoms are connected with shutoff pin 9; Piston rod 22 tops are provided with handle 1, also are with inner bag overcoat 5 outside the lucite tube inner bag 4, compress end cap 3 and are connected by locking nut 2 with inner bag overcoat 5.
As shown in Figure 2, valve piece 10 outsides are equipped with regulator 24 and at least one consistent lubricant joint 23.
The utility model utilizes the invalid vibration that produces in the quartering hammer working procedure as power resources, and when quartering hammer was started working, the vibration of its generation made steel ball 12 in the oscillatory type lubricating grease automatic filling device along with the frequency of okperation of quartering hammer play up and down together.When steel ball 12 made progress play, steel ball 12 had been removed the pressure to shift fork 15, and owing to play, shift fork 15 also has the movement tendency that is upturned simultaneously.Because the pressure of 12 pairs of shift forks 15 of steel ball is removed, plunger 17 is motion backward under the effect of piston spring 18.Under vibration force and the acting in conjunction of plunger thrust, shift fork 15 rotates, and its front end is upturned.At this moment, because the motion of plunger 17, the filler opening at plunger bushing 14 middle parts just can be opened, and lubricating grease enters into the inner chamber of plunger bushing 14 through filler opening under the pressure effect of piston 7.When steel ball 12 down moved, steel ball 12 was pressed to the below with shift fork 15, and shift fork 15 just can promote plunger 17 forward.Plunger 17 is closed filler opening when travelling forward, and pushes the lubricating grease in the plunger bushing 14 to the place ahead simultaneously.Because plunger 17 motions are very fast; Plunger front end one-way valve 13 is closed in addition; In the enclosed cavity of plunger bushing 14, can produce instantaneous high pressure, when pressure surpassed the qualification pressure of one-way valve 13, one-way valve 13 just can be opened; Lubricant grease then is pushed in the oil inlet passage, through 90 degree wire connection 11 is acted on the quartering hammer.And then get into next work cycle.
The effect of the regulator 24 on the valve piece 10 is the injection amounts that are used for regulating lubricating grease in the quartering hammer, and consistent lubricant joint 23 is that device is used for the subsequent use joint of in quartering hammer grease up when damaging.After lubricating grease in the lubricating cup uses up; Except can directly passing through consistent lubricant joint 23 grease up in lubricating cup; Also can lubricating grease lubricating cup assembly be unloaded, utilize the Oil sucking device that himself is equipped with to come grease up in lubricating cup, specific operation process is: external cover 19 parts of the output end cap on the lubricating cup are immersed in the lubricating grease; The lubricating cup assembly top handle 1 of outwarding winding then; The push-and-pull piston rod 22 back and forth, and when upwards drawing piston rod 22, the shutoff pin of opening under the suction function in fuel sucking pipe 8 in the external cover 19 of output end cap 9 sucks lubricating grease in the oil pipe 8; When down promoting piston rod 22, O type circle fixture 21 can be pressed to the below with the lubricating grease in the fuel sucking pipe 8.At this moment, lubricating cup pin 20 is closed, and shutoff pin 9 will be opened, and lubricating grease just enters into lubricating cup smoothly.Continuous push-and-pull piston rod 7, lubricating grease will constantly get into, and spring 6 is constantly compressed, and is inhaled into up to lubricating grease and limits the position.And then lubricating grease lubricating cup assembly is screwed on the valve body assembly, shutoff this moment pin 9 is opened, and lubricating grease can enter into valve piece 10.
In addition,, on the valve piece, also set up oil mass adjustment screw, the output quantity of lubricating grease is controlled effectively for the friction position that makes quartering hammer obtains a desirable lubricants capacity.On the lubricating cup assembly, be provided with the oil mass peephole, just can observe what of lubricating grease amount in the lucite tube inner bag, when low on fuel, just can in time replenish through peephole.In addition, on lubricating cup inner bag outer cover, be provided with safe-guard line and caution notice, increased the safety in utilization and the functional reliability of oil filler.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
