The specific embodiment
Below, in conjunction with the accompanying drawings and embodiments precise vacuum oiling automation line of the present invention is elaborated:
As shown in Figure 1, a kind of precise vacuum oiling automation line, comprise front belt unit 1, consisted of by roll row device and band conveyor at front belt unit 1, be provided with tray for work pieces 2 at front belt unit 1, above front belt unit 1, be provided with room detector 3, when tray for work pieces 2 passed through from its below, room detector 3 can be identified automatically to the mode of operation of tray for work pieces 2, when the workpiece room, automatic alarm, tray for work pieces 2 auto-returned original positions, prompting operation person supplies workpiece.
Side at front belt unit 1 is provided with vacuum impregnating grease chamber 4, above vacuum impregnating grease chamber 4, be provided with precision volume gauging device 5, in vacuum impregnating grease chamber 4, be provided with tray conveying apparatus 6, belt unit 7 after a side of vacuum impregnating grease chamber 4 is provided with, rear belt unit 7 is made of roll row device and band conveyor, end at rear belt unit 7 is provided with position transduser 8, and running to this place by vacuum impregnating grease chamber 4 tray for work pieces 2 out can stop automatically.
Wherein, be provided with left pneumatic door 17 in the left side of vacuum impregnating grease chamber 4, be provided with right pneumatic door 18 on the right side of vacuum impregnating grease chamber 4.
This automation line also comprises oil plant bucket 9, be respectively arranged with I vacuum oil batch can 10 and II vacuum oil batch can 11 in the both sides of oil plant bucket 9, I vacuum oil batch can 10 and I vacuum oil material conveying pump 12 are communicated with, and II vacuum oil batch can 11 and II vacuum oil material conveying pump 13 are communicated with.The outlet of I vacuum oil material conveying pump 12 and II vacuum oil material conveying pump 13 is in parallel, be communicated with precision volume gauging device 5 by expansion tank 16 usefulness vacuum oil plant pipelines 22.
