The specific embodiment
Below be instantiation of the present utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these examples.
As shown in Figure 1, the manual auto-feed converting means of this drilling and milling machine main shaft comprises gear shaft 2, handle set 7, actuating unit and clutch 5, wherein gear shaft 2 is arranged in the main spindle box 1 and is meshed with main shaft 10, and handle set 7 is fixed on main spindle box 1 outside and handle set 7 is connected with gear shaft 2 one ends.
Actuating unit comprises worm gear 11 that is connected with motor and the worm screw 12 that is meshed with worm gear 11, be equipped with on the gear shaft 2 can be on gear shaft 2 axially movable clutch cutting ferrule 6.In this example, clutch 5 is a jaw clutch, and clutch 5 comprises clutch gear 52 and clutch pawl 51, and wherein clutch gear 52 is meshed with worm screw 12, and clutch pawl 51 is connected on the clutch cutting ferrule 6.On clutch pawl 51 end faces, be fixed with clutch pawl holder 53, be fixed with steady pin 54 on the clutch pawl holder 53, be provided with back-moving spring 55 between steady pin 54 and the clutch pawl 51, back-moving spring 55 1 ends are fixed on the clutch pawl 51, and the other end is fixed on the steady pin 54.When back-moving spring 55 was undeformed, when the clutch gear 52 and the clutch pawl 51 of clutch 5 was in released state, main shaft 10 can carry out hand feed; When spring is in extended state, the clutch gear 52 of clutch 5 and 51 engagements of clutch pawl, main shaft 10 can carry out auto-feed, and after main shaft 10 auto-feeds finished, the clutch gear 52 of clutch 5 separated with clutch pawl 51 under back-moving spring 55 elastic force effects.
Feeding handle 3 and depthkeeping handle 4 are installed on handle set 7, and wherein feeding handle 3 is hinged on the handle set 7 and feeding handle 3 inner fixings in clutch cutting ferrule 6.Between handle set 7 and main spindle box 1, be fixed with dial 8, on dial 8, offer in annular groove 81 and the annular groove 81 and be provided with turnbuckle 9, depthkeeping handle 4 is connected with turnbuckle 9 one head threads, and turnbuckle 9 other ends are stuck in dial 8 annular grooves 81.The degree of depth of boring can realize that when depthkeeping handle 4 was unclamped in opposite spin, dial 8 was in releasing orientation with turnbuckle 9, can regulate drilling depth arbitrarily in allowed limits by regulating depthkeeping handle 4; When locking depthkeeping handle 4, turnbuckle 9 is in gripping orientation with dial 8.
This drilling and milling machine is when work, and motor power is delivered on the clutch gear 52 of clutch 5 by worm gear 11 and worm screw 12 successively.Under original state, the clutch gear 52 and the clutch pawl 51 of clutch 5 are in released state, and at this moment, gear shaft 2 is in released state with actuating unit, and the motor power transmission is less than on the gear shaft 2, by the feeding of feeding handle 3 manual operation main shafts 10.When 10 auto-feeds of needs main shaft, earlier depthkeeping handle 4 is counterclockwise loosened, after scale made zero, rotate scale again to desired depth, depthkeeping handle 4 is locked in the direction of the clock, pulling feeding handle 3 again moves clutch cutting ferrule 6 on gear shaft 2, the clutch pawl 51 that is connected with clutch cutting ferrule 6 under the drive of clutch cutting ferrule 6 engages with clutch gear 52, this moment, gear shaft 2 was in linkage status with actuating unit, motor power is delivered on the gear shaft 2 through clutch 5, power by actuating unit can rotate by driven gear axle 2 like this, thereby realizes main shaft 10 auto-feeds.When holing to institute's depthkeeping degree, the clutch gear 52 of clutch 5 is thrown off automatically with clutch pawl 51 and is separated feeding handle 3 automatic pop into position under back-moving spring 55 elastic force effects.If need feed-disabling midway, can pull feeding handle 3 once more in the other direction and make its playback, clutch pawl 51 breaks away from and separates with clutch gear 52, and gear shaft 2 is in released state once more with actuating unit, and main shaft 10 stops auto-feed.
Instantiation described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
