Embodiment:
Embodiment: in conjunction with Fig. 1, Fig. 2, shown in Figure 3, joining plate 25 usefulness screws 13 are installed on the worktable 1 among the figure, and pressure regulator valve 3, three-position five-way solenoid directional control valve 5, cylinder 8, fat feeding pump 11, depot fat bucket 12 usefulness screws 9 are installed on the joining plate 25.The shaft axis of cylinder 8, piston rod 10 and fat feeding pump 11 overlaps.Suction tude 2 is led to source of compressed air, and tracheae 4 is sent the pressurized air of certain pressure into solenoid directional control valve 5, and the size of pressure has pressure gauge 24 to show.Tracheae 6,7 is sent into pressurized air or export cylinder 8 again.Piston 21 has been installed with nut 22 in end at piston rod 10, and seal ring 20 is housed on the external cylindrical surface of piston.Grease-conveying tube 17 1 ends are connected in one-way valve 27, middle fixing with supporting frame 18, supporting frame 18 is fixed on the worktable with screw 19 again, and grease-conveying tube 17 the other ends are connected on the branch fat head 14 with joint 15, divide fat head 14 to be fixed on the worktable with screw 16 again, one-way valve 27 is used for controlling the output of grease.Three-pointswitch 26 is installed on the worktable 1, is used for controlling the action of solenoid directional control valve 5.Between depot fat bucket 12 and the fat feeding pump 11 one-way valve 28 is installed, is used for controlling the input of grease.
During greasing, pull the position on a left side when three-pointswitch 26, with reference to Fig. 2, Fig. 3, solenoid directional control valve 5 is in the position of A, pressurized air enters the upper end of cylinder 8,10 piston rods are moved down, driving piston 21 moves down, compression grease 23, make grease 23 open one-way valve 27 and also arrive branch fat head 14 by grease-conveying tube 17 and joint 12, with the grease injection bearing, and the one-way valve 28 of opposite side is closed at this moment, prevent that grease from blowing back into depot fat jar 12, be connected in screw rod 29 on the piston 21 and stop nut 30 simultaneously and move down with piston.Position in three-pointswitch 26 is pulled, with reference to Fig. 3, solenoid directional control valve 5 is in the position of B, and compressed-air actuated gas circuit is obstructed, and this moment, cylinder 8 was not worked, and grease injection device stops greasing.When cylinder 8 moves upward, the one-way valve 27 that is used for defeated fat is closed to prevent that grease from flowing backwards, under the effect of piston 21, fat feeding pump 11 intracavity bottoms form vacuum, under the effect of draft, the one-way valve 28 that connects depot fat bucket 12 is opened, grease enters fat feeding pump, and this moment, screw rod 29 and stop nut 30 also moved up with piston 21, till stop nut 30 and fat feeding pump 11 housing contacts, because the effect of stop nut 30, make the stroke of piston 21 certain, thereby the oil quantity that at every turn enters fat feeding pump 11 is also certain, by changing the position of stop nut 30, can change the size of each greasing amount.
The present invention contains the three-position five-way solenoid valve of cylinder, control cylinder moving direction, the pressure regulator valve of control system pressure, one-way valve, tracheae, depot fat jar, fat feeding pump, grease-conveying tube, branch fat head and the worktable composition that the control grease flows to.
Perpendicular the putting of cylinder and fat feeding pump is installed on the joining plate, both central lines, the piston rod front end of cylinder stretches into fat feeding pump and piston is installed, and the opposite side of piston is connected with a screw rod, screw rod runs through the fat feeding pump inner chamber and passes from the fat feeding pump bottom, in the screw rod lower end setscrew nut is installed.Fat feeding pump bottom one side is connected with an one-way valve and is connected to the branch finger by grease-conveying tube, and the action direction of this one-way valve is to prevent that grease from blowing back into fat feeding pump.Fat feeding pump bottom opposite side is connected with another one-way valve and is connected to the depot fat jar by grease-conveying tube, and the action direction of this one-way valve is to prevent that grease from blowing back into the depot fat jar.When cylinder moved downward, piston rod promoted piston and moves down together, and the Piston Compression grease also makes grease extrude from the one-way valve of fat feeding pump bottom one side, and grease arrives along grease-conveying tube and divides the fat head.At this moment, the closed check valve of fat feeding pump bottom opposite side prevents that grease from blowing back into the depot fat jar, and the screw rod and the stop nut that are connected in piston simultaneously move down with piston.When cylinder moves upward, the closed check valve that is used for defeated fat flows backwards to prevent grease, under the effect of piston, the fat feeding pump intracavity bottom forms vacuum, under the effect of draft, the one-way valve opens that connects the depot fat bucket, grease enters fat feeding pump, and this moment, screw rod and stop nut also moved up with piston, till stop nut and fat feeding pump housing contacts,, make the piston stroke of fat feeding pump certain because the effect of stop nut is arranged, thereby the oil quantity that at every turn enters fat feeding pump is also certain, has realized the purpose of quantitative grease-filling.By changing the position of stop nut, can change greasing amount, thereby be embodied as the purpose of the bearing quantitative grease-filling of different model.
Control the action of three-position five-way solenoid valve with the left, center, right of three-pointswitch, promptly when the position of switch on a left side, the gas circuit on the solenoid directional control valve left side is connected, and cylinder moves down, and this moment, grease was extruded.When switch during in the neutral position, solenoid directional control valve is in meta, and gas circuit is obstructed, and this moment, cylinder was failure to actuate, and grease can not be extruded yet.When switch on the right the time, the gas circuit on solenoid directional control valve the right is connected, and cylinder moves up, and realizes the process of liposuction.
