Description
Technical field
The utility model relates to mechanical manufacturing field, specifically is meant a kind of grease filling machine that component such as seal ring, bearing is carried out the inner and outer surface greasing.
Background technique
Seal ring is supportingly to play the dustproof and waterproof effect as the precision parts on the equipment rotary main shafts such as rotary drum washing machine, prevents moisture content along main shaft access arrangement inside, and assurance equipment runs well and personal safety.Seal ring the assembling before smear to surperficial quantitative and even lubricating grease within it, lubricating grease very little, then lubrication effect is not good enough, water-proof performance is poor, lubricant grease is too many, cause the waste and the obstruction equipment assembling and use.
Seal ring inner ring coating lubricating oil fat is to use manual work at first, smears by hand; Used lubricant grease holster gun barrel afterwards instead,, lubricant grease was injected the seal ring inner ring equably by the lubricant grease holster is exerted pressure.Do like this and two problems can occur: the one, injection amount is inconsistent, and in time, lacked for a long time; The 2nd, smear inhomogeneous.
Occurred the way of using grease filling machine to carry out mechanical greasing at present, mainly contain three kinds: one is to use pressure, lubricant grease is evenly injected treat lubricating component; Two are to use the spiral rod type greasing, along with the rotation of screw rod, grease injected quantitatively treat lubricating component; Three are to use cylinder to replace screw rod, make greasing more even, Chinese invention patent " the quantitative grease filling machine for sealed low noise bearing " (patent No.: ZL200510017956.3) for example, main structure is that cylinder adds fat feeding pump, the lifting of pressurized air by the solenoid directional control valve control cylinder, thereby the greasing of control fat feeding pump and from the liposuction of depot fat bucket, because fat feeding pump is a reciprocating pump, therefore can not realize the accurate quantification greasing fully, especially for the following a small amount of greasing of 5 grams.
The model utility content
Can not realize accurate quantification greasing problem fully in order to solve the grease filling machine that prior art exists, the utility model proposes a kind of simple in structurely, make, use, safeguard easily, can realize a kind of grease filling machine of accurate quantification greasing fully.
The technological scheme that the utility model uses is as follows:
A kind of grease filling machine comprises the lubricating grease storage, cylinder, the two-position-five-way solenoid valve that are linked in sequence, and circuit and compressed air system, is provided with gear pump between lubricating grease storage and cylinder.The grease inlet of described gear pump is communicated with the lubricating grease storage; The gear pump grease outlet connects greasing head by fat guiding tube.The lubricating grease of lubricating grease storage directly enters gear pump, is sent to greasing head under the driving of gear pump.
Described cylinder is the gear rack oscillating cylinder; The live axle of gear pump is connected by the output shaft of unilateral bearing with the gear rack oscillating cylinder.The left gas port of described gear rack oscillating cylinder and right gas port are connected the left tracheae and the right tracheae of two-position-five-way solenoid valve respectively; Greasing is provided with the switch that is electrically connected with two-position-five-way solenoid valve in front.
When opening switch, the two-position-five-way solenoid valve connecting rod is moved to the left, and the rack and pinion that pressurized air promotes in the gear rack oscillating cylinder rotates, and gear connects unilateral bearing, and the driven gear pump rotates, and lubricating grease is sent to greasing head and carries out the greasing operation.During off switch, the two-position-five-way solenoid valve connecting rod resets, and promptly connecting rod moves right, and gear and tooth bar in the gear rack oscillating cylinder move in opposite directions, and one-way shaft is made the running of sliding, and gear pump does not rotate, and stops the greasing operation.
The beneficial effects of the utility model are:
1) gear pump is a kind of metering pump, gear driven gear pump during operation in the gear rack oscillating cylinder fixedly turns an angle, and the lubricating grease of certain volume is sent to greasing head, and the quantitative grease-filling operation is carried out in strictness, for the following a small amount of accurate quantification greasing of 5 grams, precision can reach 5 grams ± 0.1 gram.
2) with hand seal ring is placed on the greasing head gently one by, switch opens during operation, the greasing operation begins; Use hand rotary seal circle then, lubricating grease spreads upon in the seal ring equably, decontrols the seal ring in the hand, and switch cuts out, the greasing end of job.Therefore, the utility model is simple in structure, makes, uses, safeguards easily.

Embodiment
Fig. 1 is the grease filling machine schematic representation.Top is lubricating grease storage 1, the bottom connection gear pump 2 of lubricating grease storage 1, and the grease inlet 21 of gear pump communicates with the lubricating grease storage.Lubricating grease can directly enter gear pump 2, and gear pump grease outlet 22 connects greasing head 5, Fig. 2, Fig. 4, shown in Figure 6 by fat guiding tube 8.The live axle of gear pump is connected with the output shaft of gear rack oscillating cylinder 4 by unilateral bearing 3.Greasing head 5 limits are provided with switch 51, and the power supply of control two-position-five-way solenoid valve 6 opens and closes.Two-position-five-way solenoid valve left side tracheae 91 and right tracheae 92 are communicated with the left gas port 43 and the right gas port 44 of gear rack oscillating cylinder, as Fig. 1, shown in Figure 3.Suction port 63 at two-position-five-way solenoid valve feeds pressurized air, just can carry out operation.
The effect of unilateral bearing is: rotating shaft can only be turned round along a direction, and when turning round in the other direction, axle and bearing can only slide, and can not drive its rotation.That is to say that can rotate by the driven gear pump when output shaft of gear rack oscillating cylinder is just changeing, output shaft rotates during counter-rotating, gear pump does not rotate.
With hand seal ring 7 is placed on the greasing head 5 gently one by, switch opens during operation, the greasing operation begins, as Fig. 4, shown in Figure 5; Use hand rotary seal circle then, lubricating grease spreads upon in the seal ring equably, and the seal ring in the hand is taken from greasing head, and switch cuts out, and the greasing end of job is as Fig. 6, shown in Figure 7.
