When the motor shaft clamped by the rotary air cylinder 506 rotates, the matched moving cylinder 514 at the other end of the motor shaft synchronously rotates, the matched moving cylinder 514 rotates to drive the pushing plate 713 to synchronously rotate, the pushing plate 713 rotates to push the bottom plate 712 to transversely reciprocate through a plurality of protruding blocks close to one side of the bottom plate 712, so that when the brush plate 711 above the bottom plate 712 is closely attached to the motor shaft, scrap iron attached to the surface of the motor shaft can be cleaned in a shaking posture, and the motor shaft can be cleaned better;
And, when the push plate 713 pushes the bottom plate 712 to move through the bump, at this time, the bottom plate 712 will apply a pushing force to the buffer spring disposed inside the moving frame 702, so that the spring is deformed, when the bump on one side of the push plate 713 no longer pushes the bottom plate 712 to move, the buffer spring will reset the bottom plate 712, so that one end of the bottom plate is always in close contact with one side of the push plate 713, and the bottom plate 712 can stably drive the brush plate 711 to clean the scrap iron on the surface of the motor shaft.
Referring to fig. 10 to 11, a chute is formed on the inner side of the adjustment table 505, the auxiliary mechanism 7 further includes a gravity ball 714 disposed inside the chute, a ring 716 is rotatably connected to the surface of the gravity ball 714, a scraper 715 is detachably connected to one end of the ring 716, one end of the scraper 715 in contact with the adjustment table 505 is in a telescopic arrangement, and a pair of collection bins 9 are mounted inside the adjustment table 505.
When the motor shaft is turned over by the adjusting table 505, the gravity ball 714 positioned inside the adjusting table 505 slides inside the chute formed in the inner side of the adjusting table 505 when the motor shaft is turned over from the horizontal state to the vertical state, the gravity ball 714 slides along the chute towards the collecting bin 9, the ring 716 rotationally connected with the gravity ball is driven to synchronously slide along the limit strip 717, the ring 716 further drives the scraper 715 to scrape and slide towards the collecting bin 9 inside the adjusting table 505, the adjusting table 505 is just turned over from the horizontal state to the vertical state at the moment, and the deep keyway processing is just completed on the motor shaft, scrap iron left during the deep keyway processing slowly flows into the collecting bin 9 during the turning over of the adjusting table 505, and for scrap iron with larger adhesive force, the gravity ball 714 slides inside the adjusting table 505 through the scraper 715 driven by the ring 716, so that the scrap iron can be scraped inside the adjusting table 505, the scrap iron inside the adjusting table 505 is swept into the collecting bin 9 to be collected, and the effect of the motor shaft during the shallow keyway processing can be effectively avoided;
moreover, because the position that scraper blade 715 contacted with adjustment platform 505 is flexible setting, when gravity ball 714 passes through ring cover 716 and drives scraper blade 715 when the inside slip of adjustment platform 505, one end of scraper blade 715 can be all the time with the inside contact of adjustment platform 505 for scraper blade 715 can clear up the inside of adjustment platform 505 steadily, and because the chute of adjustment platform 505 inboard is offered and is shown in fig. 10 and 11, when gravity ball 714 slides in the chute this moment, can produce certain acceleration, makes scraper blade 715 can slide in the inside of adjustment platform 505 rapidly, clears up its inside iron fillings.
Referring to fig. 10 to 11, a limit bar 717 is slidably connected to the outer side of the collar 716, the limit bar 717 is fixedly connected to the adjustment table 505, the limit bar 717 has the same size as the chute, and a pair of baffles 10 are disposed inside the adjustment table 505.
When the motor shaft is driven by the adjusting table 505 to synchronously turn over, the gravity ball 714 slides in the chute at this moment, the ring 716 rotationally connected with the surface of the gravity ball 714 slides in the inner side of the limit strip 717 until the gravity ball 714 reaches a specified position in the chute, and moves in an acceleration state when the gravity ball 714 slides in the chute, when the scraper 715 approaches to the position of the collecting bin 9, the iron filings with stronger adhesive force in the adjusting table 505 can be better pushed to the inside of the collecting bin 9 for collecting, and the situation such as position deviation of the scraper 715 in the moving process can be prevented due to the limitation of the ring 716, so that the effect and stability of the scraper 715 on cleaning the iron filings can be fully improved;
Moreover, through setting up a pair of baffle 10 in the inside of adjustment platform 505, when scraper blade 715 slides in the inside of adjustment platform 505, scraper blade 715 can be in one side motion of baffle 10 this moment, and baffle 10 can prevent that iron fillings etc. from influencing and moving frame 702 at the inside gliding effect of adjustment platform 505 on the one hand, on the other hand can just overturn the inside that is the iron fillings direction collection storehouse 9 under the vertical state with adjustment platform 505, conveniently collect storehouse 9 and collect it, after the iron fillings that collect in collection storehouse 9 reaches the moderate amount, only need collect storehouse 9 dismantle the clearance can.
Referring to fig. 6 to 11, a sealing gasket is disposed at a sliding position between the moving frame 702 and the adjustment table 505, one end of the bottom plate 712, which is far away from the pushing plate 713, is slidably connected to the moving frame 702, the sliding position is provided through, and a return spring is disposed at a sliding position between the sliding column 704 and the adjustment table 505.
During operation, through setting up sealing washer in the position of removing frame 702, when part iron fillings get into the position between a pair of baffle 10, with the surface contact of removing frame 702, sealing washer can prevent that the iron fillings from disturbing and remove frame 702 and support the motor shaft at the inside up-and-down motion of adjustment platform 505 this moment to through setting up into sliding connection between bottom plate 712 and the removing frame 702, can control brush 711 above the bottom plate 712 better clear up the remaining iron fillings in motor shaft surface, prevent that the motor shaft from being influenced by the iron fillings when rotatory processing, can improve the effect of brush 711 to the motor shaft clearance effectively.
