A process for treating the surface of a bearing flange of an automobile wheel hub by using automobile wheel hub bearing surface treatment equipment comprises the following process operation flows:
s1: positioning holes of the automobile hub bearing flange are aligned with the limiting columns 4 and placed on the limiting seats 3;
s2: the automobile hub bearing flange is fixed by pressing the pressing fastener 5;
s3: the gear disk 39 rotates to drive the automobile hub bearing flange to rotate so that the spline grooves to be cleaned are aligned with the cutter head 31;
s4: the tool bit 31 extends into the spline groove and then presses against the groove surface of the spline groove and cleans the groove surface;
s5: if the cutter head 31 is blocked by the dirt and cannot move, the cutter head 31 rotates to crush the dirt;
s6: the cutter head 31 extends to the flange end face to treat stains;
and S7, turning the angle of the automobile wheel hub bearing flange, and repeating the steps until the whole automobile wheel hub bearing flange is cleaned.
Working principle:
the blind hole alignment limit post 4 of automobile wheel hub ring flange is put into on the limit seat 3, presses down fastener 5 once, and limit seat 3 and limit post 4 fix a position automobile wheel hub ring flange. The hydraulic telescopic rod 2 is controlled to extend towards the flange, the output end of the hydraulic telescopic rod 2 is abutted against the surface of the flange, and the head of the screw rod 15 extends into the flange.
The hydraulic telescopic rod 2 is driven to move downwards, so that the cutter head 31 is driven to be pressed into a spline groove of the flange plate, the telescopic motor 14 is started to drive the screw rod 15 to push out of the flange plate of the automobile hub, after the cutter head 31 stretches into the flange plate of the automobile hub, the cutter head 31 is pressed into the spline groove in the flange plate, and the spring 51 is compressed, so that the cutter head 31 has radial pressure on the wall surface of the spline groove. The spring 51 is arranged to avoid abrasion caused by excessive force when the cutter is initially contacted with the flange.
The telescopic motor 14 is continuously ejected to drive the scraper block 16 to move, and when the force required for cleaning the stains encountered by the scraper block 16 is not large, the cutter head 31 does not rotate to scrape the stains on the wall surfaces of the spline grooves. At this time, the connection block 21 moves together with the screw 15, and no transmission is performed.
If the dirt is blocked from moving during scraping, the telescopic motor 14 continues to extend, the scraper block 16 cannot continue to extend along with the spiral rod 15, but the spiral rod 15 extends to enable the connecting block 21 to rotate relative to the scraper block 16, the first bevel gear 25 in the middle of the outer ring of the connecting block 21 drives the second bevel gear 28 to rotate, the second bevel gear 28 drives the first rotating shaft 27 to rotate, the cutter head support rod 30 can synchronously rotate along with the first rotating shaft 27, so that the cutter head 31 rotates to break dirt which is blocked from moving, and after breaking is completed, the cutter head 31 continues to extend along with the spiral rod 15 to clean the inner surface of the spline groove.
After the inner wall of the spline groove of the cutter head 31 is cleaned and extends out of the automobile hub bearing flange, the cutter head 31 pops up under the action of a spring, so that the cutter head 31 extends out of the spline groove to reach the flange end face, a first clamping block 43 on the first retaining cylinder 19 extends into a first clamping seat 44 in the scraper block 16 to fix the scraper block 16, the cutter head 31 is fixed because the scraper block 16 is fixed, and at the moment, the telescopic motor 14 continues to push the screw rod 15 to the bottom forwards, so that the direction of the final cutter head 31 is that the side face contacts with the flange end face.
The first motor 37 drives the gear disc 39 to rotate, the gear disc 39 drives the automobile wheel hub bearing flange to rotate, and the stationary cutter head 31 starts to clean the end face of the rotating automobile wheel hub bearing flange.
After the end face cleaning is completed, the first motor 37 stops rotating, the tool bit 31 corresponds to the initially cleaned spline groove, the hydraulic telescopic rod 2 is controlled to move upwards, the tool bit 31 is lifted away from the height of the spline groove, the telescopic motor 14 drives the tool bit 31 to retract, after the tool bit enters the range of the spline groove of the hub bearing flange of the automobile wheel, the telescopic motor 14 stops retracting, the hydraulic telescopic rod 2 is controlled to move downwards, and the tool bit 31 is driven to press the inner wall of the spline groove.
The telescopic motor 14 continues to retract until the second clamping block 46 on the first blocking cylinder 19 is inserted into the second clamping seat 47 on the scraper block 16, the cutter head 31 extends out of the projection range of the spline groove, cleaning and scraping are continued in the process until the cutter head extends out of the end face of the automobile hub bearing flange, the scraper block 16 is fixed by the second clamping block 46, the cutter head 31 on the scraper block 16 is fixed, the first motor 37 drives the automobile hub bearing flange to rotate again, and the cutter head 31 cleans the other end face of the automobile hub bearing flange.
The lead screw slider mechanism 42 drives the carrier 41 up to a height that extends into the spline grooves and the first motor 37 rotates to align the bit 31 with the second spline groove.
Repeating the steps until the spline grooves of the automobile wheel hub flange and the stains on the end surfaces of the spline grooves are cleaned.
