Description
Technical field
The utility model relates to drilling machine technology, is specifically related to the clutch of a kind of drilling machine band steel ball.
Background technique
Drilling machine is mainly used in processing various hole.Drilling machine structure is simple, can holes drilled through, blind hole, after changing special tool, can reaming, spot-facing, ream or carry out the processing such as tapping.The dynamic structure that moves through of drill bit drives, and bit is main movement, and drill bit moves axially as feed movement.The retarder that dynamic structure comprises the clutch in motor, motor flywheels shell and is connected with clutch output shaft, the output shaft of retarder is connected with drilling rod and drives drilling rod to move.Clutch is used for temporarily being separated or engaging of motor and retarder, makes power temporarily export or interrupt.At present, drilling machine is at work, owing to being subject to the impact of external environment, easily stuck during bit bore, in such cases, if power continues to export, then easily damages motor.
Model utility content
The utility model provides a kind of drilling machine to be with the clutch of steel ball, with when drill bit is stuck, and unpowered output, protection motor.
The utility model scheme is as follows: the clutch of drilling machine band steel ball, comprise clutch disk, axle sleeve and platen, clutch disk connects Power output, clutch disk is together with axle sleeve empty set, the right card of clutch disk is circumferentially evenly equipped with multiple hemisphere blind hole, the periphery of axle sleeve is provided with a circle flange, flange is evenly equipped with multiple through hole along the circumference of flange, the position of each through hole is relative with the position of hemisphere blind hole, a steel ball is equipped with in each through hole and hemisphere blind hole, the right side of steel ball is compressed by the platen of empty set in axle sleeve periphery, steel ball is made to be connected in hemisphere blind hole, helical spring is provided with in the periphery of axle sleeve, helical spring left end props up the right side of platen, the right side of clutch disk and the left side of flange offset, the periphery of axle sleeve is provided with circlip, the right side of circlip and the left card of clutch disk offset.
This programme working principle and effect as follows: clutch disk is by circlip axially locating on axle sleeve, during clutch normal engagement, steel ball is placed in the hemisphere blind hole of clutch disk and the through hole of bushing collars, rely on helical spring impacting force, by platen, steel ball is compressed, clutch disk drives axle sleeve synchronous axial system, and power is inputted by clutch disk, and axle sleeve exports.In drilling machine boring procedure; if there is drill bit stuck phenomenon; then axle sleeve cannot rotate stuck moment; and motor can continue to drive clutch disk to rotate; helical spring impacting force is not enough to make platen hold out against steel ball, and the rotation of clutch disk will make steel ball extrude hemisphere blind hole, thus makes clutch disk drive axle sleeve to rotate again; cut off power, play the effect of overload protection.
Further; also comprise housing; housing comprises end cap and the protecting jacket with end cap one; end cap empty set is on axle sleeve; left side and the helical spring of end cap offset; the periphery of axle sleeve is fixed with positioning retainer ring, and the right side of end cap and the left side of fixing back-up ring offset, the coated helical spring of protecting jacket, flange and clutch disk.Housing all has protective action to helical spring, flange and clutch disk, prevents the interference being subject to external environment when using, prevents the erosion being subject to dirt.
Further, helical spring of the present utility model is conical helical spring.The rigidity of conical helix spring, progressively increases along with the minimizing of number of active coils.Conical helix spring is conducive to preventing resonance from occurring, can effective vibration damping.
Further, circlip of the present utility model has two, and wherein the first circlip is fixed in the annular slot of axle sleeve, offsets on the left of the second circlip with the first circlip, and right side props up the left card of clutch disk.Two circlips are set, more stable when clutch engaging power, thus make Power output more stable.
