As shown in Figure 2, in conjunction with Fig. 1, cylindrical shell 13 is installed on the support 54, and worm screw 32 is fixedly mounted between the opening of upper shell 4 and cylindrical shell 13 by bearing 28.The right-hand member of worm screw 32 is installed belt pulleys 34 by key 35, and small belt pulley 52 is installed on the motor 53, is connected with active inverted triangle belt 33 between belt pulley 34 and the small belt pulley 52.
This device provides hand-operated feed and has fed dual mode automatically, and its operation principle is as follows respectively:
Job order during auto-feed is: at first, fastening nut 39, hand wheel shaft 61 closely is connected with screw mandrel 15, and screw mandrel 15 is fixed; Then, the actuating motor motor, → motor drives motor pulley and rotates, → driving driven pulley rotations → worm screw rotation → worm gear rotation → power transmission shaft rotation → reamer bar rotation → Hough clamp ring rotation → planetary gear rotation → transmission nut on the worm screw on screw mandrel, to rotate → owing to screw mandrel is fixed, transmission nut is moved to the left → promotes the plane thrust bearing and is moved to the left → drives reamer bar and be moved to the left → reamer feed left on screw mandrel.
Job order during hand feed is: at first, unclamp nut 39, hand wheel shaft 61 disconnects with screw mandrel 15 and being connected, and screw mandrel 15 can freely rotate; At this moment, then, the actuating motor motor, → motor drives motor pulley and rotates, driven pulley rotation → worm screw rotation → worm gear rotation → power transmission shaft rotation → reamer bar rotation → Hough clamp ring rotation → planetary gear rotation → drive transmission nut on the → drive worm screw rotates on screw mandrel, this moment, screw mandrel rotated with transmission nut, transmission nut do not take place to left → plane thrust bearing motionless → reamer bar is not moved to the left; At this moment, rotating handwheel → drive screw mandrel rotation → promotion gear nut is moved to the left → promotes the plane thrust bearing and be moved to the left → drive reamer bar and be moved to the left → reamer feed left.
During withdrawing, when motor operations: unclamp that nut → backward rotation handwheel → screw mandrel driven gear nut counter-rotating → promotion Hough clamp ring is parallel to be moved to the right → drive reamer bar to move right → withdrawing.
For satisfying boring demand in particular cases, this broach(ing) machine also has the boring function, only needs reamer is changed to the drill bit of regulatory specifications.Can use T8 tool steel reamer during ream, use carbide drill during drilling.The range of this device: 394mm; Reamer bar rotating speed: 36.1r/mm, auto-feed speed: 9.3mm/min; The reamer depth of cut: 0.014mm/r during autofeed; The drill bit depth of cut: 0.26mm/r during autofeed, the range of work is φ 25mm～φ 55mm.Consider tool industry tapering Morse's taper broach(ing) machine commonly used, spindle taper hole adopts the 5# Morse's taper, so that be suitable for the reamer and the drill bit of all size.Under load test, have following characteristics:
1. by the rated speed load test have respectively manually, autofeed dual mode fraising.When manually feed is holed under rated speed, the depth of cut≤0.05～0.09mm/r.
2. stable working do not have creep, friction, nothing are impacted, no abnormal noise, the operation light and flexible is moved fluent phenomenon.
3. load and check main shaft axial runout and circular runout≤0.015 after the test run.
