The specific embodiment
Be further described below the utility model.Generator, motor stator punching surface flash trimmer, comprise frame (1), with the matched reduction box transmission mechanism (5) of motility mechanical, it also comprise by last roll shaft (23) and lower roller shaft (41) constitute a pair of upper and lower mutual over against roll shaft; The left and right two ends of lower roller shaft are installed on the frame by bearing and bearing block, the output shaft engagement of the gear (11) of the load axle right-hand member of right-hand member by being installed in lower roller shaft and reduction box transmission mechanism (5).Last roll shaft left end tape spool holds and bearing spider II (35), and the right-hand member tape spool holds and bearing spider I (12).The bearing spider II (35) at the left and right two ends of last roll shaft and bearing spider I (12), place respectively in the vertical slideway in a left side and right vertical slideway of frame, this slideway can be vertical groove, it also can be the space that fences up by the object that is fixed on the hard straight panels, the same with the space that block II (54) fences up as the vertical slideway in a left side by block I (57), its effect is to limit the direction of motion that goes up roll shaft bearings at both ends bearing, only allow them to do the motion of vertical direction, do not allow them to do left and right motion and seesaw.
Last roll shaft left end shaft is held the upper surface of bearing II (35) and the upper surface of last roll shaft right-hand member bearing spider I (12) is subjected to stage clip II (31) and the effect of stage clip I (15) lower end respectively.The upper end of stage clip II (31) and stage clip I (15) acts on the lower surface of spring backing plate II (29) and spring backing plate I (17) respectively; The upper surface of spring backing plate II (29) and spring backing plate I (17) is inconsistent with the lower end that is spun on exert pressure the screw rod II (27) and the screw rod I (19) that exerts pressure in the frame screw respectively; The screw rod II (27) and screw rod I (19) upper end of exerting pressure stubborn bar II (25) of band application pressure hand and the stubborn bar I (21) of the hand of exerting pressure respectively exert pressure.The hand of exerting pressure is twisted bar and is used for the free-hand turn screw rod of exerting pressure, by the stroke of spring backing plate at the amount of the moving up and down control stage clip of vertical direction, allow stage clip that suitable active force is applied on the top roll axle bearing bearing, certain rolling pressure when forming the roll shaft roll extrusion.The active force scope that the unit width stator punching is bestowed is 6000～10980N/m.
The bearing spider II (35) at the left and right two ends of last roll shaft and bearing spider I (12) all are with the low inclined plane, preceding high back of hanging by the feet; Tiltedly contract II (55) and oblique contract I are inserted in respectively under two inclined planes backward by preceding, and respectively and between the accent of rack-mounted front and back horizontal positioned between the accent of screw rod II (33) and front and back horizontal positioned screw rod I (13) matched by screw and screw thread.Screw rod is used to promote oblique contract and moves forward and backward between accent, and the ramp effect that makes oblique contract is in bearing spider, and then will go up roll shaft and lift or put down along vertical slideway.Screw rod whenever circles between accent, and tiltedly contract moves forwards or backwards a pitch, and owing to the tiltedly effect on contract inclined-plane, the distance that last roll shaft is lifted and puts down is the pitch of screw rod between transferring and the product of oblique contract inclination tangent of an angle.Therefore, screw rod can adjust the variable quantity in very little upper and lower roll gap (distance) between accent.Between accent screw rod II (33) by with the carrying in the rack-mounted short cylindrical shape of the short cylinder hole of the concentricity line of shaft, the short cylindrical shape hole is enclosed in whole short circle in the hole by the Ka Gai (56) that is fastened on the frame, make that screw rod II (33) can rotate between accent in cylindrical hole, can not move forward and backward.
The thickness of stator punching is much larger than the burr particle diameter, quick adjustment goes out to be suitable for the distance between the upper and lower roll shaft that stator punching passes in order to install, the left and right two ends of the roller of the utility model lower roller shaft increase respectively and put positioning ring II (39) and positioning ring I (7), and positioning ring is that the cross section is the annulus of rectangle.The thickness of the thickness=stator punching of positioning ring-pre-crush, pre-crush is generally between 0.04～0.06mm.Therefore, the process of collar external diameter has guaranteed certain batch pre-crush of the needed the best of (thickness) stator punching.One of installation way is enclosed within two identical positioning rings respectively on the roller two ends of lower roller shaft exactly, uses sunk screw along radially positioning ring being fastened on the roller then.Like this, because the effect of stage clip II (31) and stage clip I (15), the roller two ends of last roll shaft (23) just directly rest on the positioning ring II (39) and positioning ring I (7) at the left and right two ends of roller of lower roller shaft (41), and the gap width in the middle part of between the upper and lower roll shaft equates with the thickness of positioning ring.Obviously, first effect of positioning ring is to have determined minimum clearance between the roller of double-roller, it avoided effectively stator punching in incision and the section of withdrawing from (fanning strip mostly is the trigonum) because section problem that the little material of pressure-bearing surface is crushed out of shape has guaranteed the integrality of stator punching after the deburring.Second effect of positioning ring is to drive to go up the roll shaft rotation, is convenient to stator punching and nips.The 3rd effect of positioning ring can be replaced with different-thickness easily, this makes the utility model deburring function adapt to the stator punching of different-thickness easily, made things convenient for the stator punching of handling different-thickness batch widely, and since the positioning ring after the wearing and tearing that work long hours change.
For roll shaft has enough rigidity, the two ends end cap that constitutes the several sections of roll shaft that is load axle, roller and roller is fixed on the load axle integrally can be connected as one, inner solid, the roll shaft rigidity that makes like this is bigger.Smooth, smooth for the roller surface of accomplishing upper and lower roll shaft, roller can adopt 45# steel material to make, and the surface is through over carburizing heat treatment, and the heat treatment technics condition is HRC60-64; Roughness is Ra1.6.Roller radius r=0.065m.Roll shaft rotating speed 40r/min can satisfy the demand.
The utility model stator punching surface flash trimmer is prepared positioning ring earlier before producing use in batches.Remove the thickness of certain batch of stator punching of burr as required, screw rod between adjusting earlier, make gap=stator punching between the upper and lower roller thick-pre-crush.Burr varies in size, and its pre-crush that needs is slightly variant, but same batch stator punching, the burr size is basic identical, and needed pre-crush is same amount basically.Adjust crush and spring pressure by pressure testing, determine the best pre-crush upper and lower roll distance between axles of actual measurement (pre-crush=stator punching is thick-), and prepare positioning ring thus, be loaded on the roller two ends of lower roller shaft.Accurately locate upper and lower roll distance between axles with this, and drop into and produce in batches.The last hand of exerting pressure that utilizes is again twisted the suitable roll-in pressure of bar adjustment.The roller surface linear velocity of upper and lower roll shaft is realized by the gearratio of reduction box transmission mechanism.Roller radius r=0.065m, roll shaft rotating speed 40r/min can satisfy the demand.Stator punching is sent between charging left side plate washer (37) and the right baffle plate of charging (8), skids off between discharging right baffle-plate (53) and the right baffle plate of discharging after being nipped by upper and lower roll shaft, finishes the removing of the burr face of stator punching.Because the roll shaft pressure stability is adjustable, positioning ring has guaranteed that effectively upper and lower roll distance between axles does not change, also just guaranteed the stability of the utility model stator punching surface flash trimmer operating mode.
The removal method of a kind of generator, motor stator punching surface burr, it has following three features: (i) utilize the roll extrusion on stator punching burr face of the smooth smooth roll shaft of roller surface; Described roll shaft is made up of by the end cap that roller and load axle are fastened as one at roller two ends roller and the load axle that passes roller inside center line; (ii) the roll shaft unit width active force of bestowing stator punching by roller surface is 6000～10980N/m; This width calculates with the straight length that stator punching burr face contacts with roller surface.Therefore, when the limit of stator punching was parallel to the central axis of roll shaft, the length of side of stator punching was the width of using when calculating the required amount of force of stator punching.(iii) roller surface linear velocity 0.22～0.32m/s.The linear velocity of best roller surface is 0.27m/s.
Stator punching adopts fragile materials to make such as silicon steel sheet more, and the burr that is produced by punching press forms extremely thin tiny steel cuttings and comes off from root basically through rolling, and can see the impression bright spot in the burr position of stator punching burr face with the magnifying glass observation.Burr from the teeth outwards, the mechanical energy that need to absorb from roller surface goes to pulverize.Roll shaft rotates too fast, is unfavorable for that burr absorbs energy and pulverizes; Rotate too slowly, do not utilize again and boost productivity.The roller linear velocity of roll shaft is 0.27m/s, and the production practices proof can obtain reasonable deburring effect.
Roller surface is smooth, smooth, has guaranteed that all burrs that exceed surface (plane) of in deburring process stator punching surface all are subjected to active force and are eliminated clean.The suitable rolling pressure and the linear velocity of roller surface, the quality and the efficient of the stator punching after the utility model is removed the deburring of burr method have been guaranteed, make the stator punching good hand touch, flat appearance (polishing scratch that does not have the grinder buffing deburring to stay) attractive in appearance, the elimination efficiency height has satisfied batch production requirement.
