Detailed description of the invention
Below in conjunction with accompanying drawing and concrete preferred embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, the automatic press-in device of a kind of fuel sucking pipe, comprises fuel sucking pipe conveying press-in device and workpiece conveying and positioning device.Fuel sucking pipe carries press-in device to comprise vibrations charging tray storehouse 13, feed arrangement 4, shifting apparatus 5, clamping device 8 and press-in device 6; Workpiece conveying and positioning device comprises line body 1, jacking apparatus 2 and the centring means 3 carried for workpiece (the present embodiment is freezer compressor, lower same); On line body 1, be disposed with dead point release unit 10 and the bent axle device 11 that sets right, before effectively overcoming fuel sucking pipe 15 and being pressed into, bent axle rests on the phenomenon that dead point does not rotate or crank position is not positive.As shown in Figures 2 and 3, dead point release unit 10, can be used for bent axle to depart from from dead point, it includes the first blocking mechanism 14 for stopping working plate 16 and a roots and tops and is provided with the flexible push rod 12 of deep groove ball bearing 7, and flexible push rod 12 is preferably flexible by being fixed on air cylinder driven on support 17.The bent axle device 11 that sets right, for crank position is set right, as shown in Figure 2 and Figure 4, it includes the second blocking mechanism 20 and a flexible copper coin 19 for stopping working plate 16, and flexible copper coin 19 is preferably flexible by being fixed on air cylinder driven on support 17.Comprise on line body 1 and be also provided with photoelectricity correlation closing detecting apparatus 9, whether these photoelectricity correlation closing detecting apparatus 9 energy fuel sucking pipes 15 have been pressed in bent axle and whether the height being pressed into meets the requirements etc.
On above-mentioned press-in device 6, be provided with pressure-reducing valve 18, energy automatic pressure-reducing; Press-in device 6 bottoms are provided with pressure sensor, and this pressure sensor can detect the pressure that press-in device 6 bears, and are also the pressure that indirectly testing workpiece bears, in the time that pressure is excessive, and energy automatic alarm, thus prevent that workpiece from damaging because pressure is excessive.
On above-mentioned jacking apparatus 2, be provided with spring bumper, can effectively disperse excessive pressure, protection workpiece is not damaged.
In above-mentioned vibrations charging tray storehouse 13, be provided with the height sensor that can detect fuel sucking pipe 15 height, this height sensor can shake the fuel sucking pipe of needs height 15 go out from vibrations charging tray storehouse 13.
This device motion process is as follows:
1. workpiece conveying and positioning device motion process: the working plate 16 that workpiece is housed moves to the process of jacking apparatus 2 from line body 1, the dead point release unit 10 that is positioned at line body 1 side acts on, its first blocking mechanism 14 stops working plate 16, rear flexible push rod 12 stretches out, the deep groove ball bearing 7 that is positioned at its top rotates after encountering the bent axle of workpiece, and bent axle is departed from from dead-centre position.Then, the first blocking mechanism 14 is let pass, working plate 16 continues to move to jacking apparatus 2, the bent axle device 11 that sets right acts on, its second blocking mechanism 20 stops working plate 16, rear flexible copper coin 19 stretches out, and flexible copper coin 19 can be shifted bent axle static random site onto operating position state, and bent axle is set right.Then, working plate 16 continues to move to jacking apparatus 2, and jacking apparatus 2 is by 16 jack-up of the working plate with workpiece, and centring means 3, by bent axle stationary positioned, can not freely rotate it, waits for that press-in device 6 is pressed into fuel sucking pipe 15.
2. fuel sucking pipe is carried press-in device motion process: the height sensor in vibrations charging tray storehouse 13 can be distinguished the fuel sucking pipe 15 of differing heights, and the fuel sucking pipe 15 that needs height is shaken from vibrations charging tray storehouse 13; Shake fuel sucking pipe 15 is out rotated into vertical direction by pay-off 4, delivers to the working region of shifting apparatus 5; Shifting apparatus 5 gripping fuel sucking pipes 15, be transplanted on bent axle in working plate 16 directly over, and fuel sucking pipe 15 is put into clamping device 8 the insides; Clamping device 8 fuel sucking pipe 15 is placed into bent axle directly over center more nearby.Now, the pneumohydraulic pressure-cylinder of press-in device 6 starts supercharging, presses down.Press down in process, the pressure sensor of press-in device 6 bottoms can detect the pressure that press-in device 6 bears, and is also the pressure that indirectly testing workpiece bears, in the time that pressure is excessive, and energy automatic alarm, thus prevent that workpiece from damaging because pressure is excessive.Pressure-reducing valve 18 energy automatic pressure-reducings, spring bumper also can provide a cushion effect to workpiece, further prevents workpiece to damage by pressure.
3. fuel sucking pipe is pressed into position probing: when press-in device 6 presses down fuel sucking pipe 15, the photoelectricity correlation checkout gear 9 that opens the light will be opened automatically, detects whether fuel sucking pipe 15 has been pressed into bent axle and whether the height that is pressed into meets the requirements.When compression distance reaches when setting value, information is offered press-in device 6 by the photoelectricity correlation checkout gear 9 that opens the light, and press-in device 6 will stop lower press operation.So, fuel sucking pipe 15 is just successfully pressed in bent axle.Press down in process, jacking apparatus 2 also self has elastic buffering mechanism concurrently, prevents that workpiece from being damaged by pressure.
In the above-mentioned course of work, successfully solve the location of bent axle and workpiece and the insoluble problem in prior art by pressure such as damaged.In addition, the work of this device each several part is separate, independently shakes charging tray storehouse 13 material loadings, independently workpiece automatic in-position, independently fuel sucking pipe 15 self-feedings, independently press-fiting of fuel sucking pipe 15 and bent axle.This four mode of operation greatly independently, automaticity is high, has improved greatly operating efficiency, and the fastest beat can reach 6s/ part at present.
