Description
Technical field
The present invention relates to a kind of machining tool, more particularly, to a kind of pulse shock Hand driling tool.
Background technology
The existing hand drilling tool of a class, by shaking drive disk, is rotated using the sliding tooth on drive disk come drive shaft,
And then drive bit to realize drilling.Scrap is produced in boring procedure, scrap easily blocks drill bit, it is necessary to invert drill bit
Withdrawing outside scrap tap, will be further continued for drilling.But this kind of hand drilling tool, can only when needing drill bit to invert withdrawing, chip removal
Realize that drill bit is inverted by reversely shaking drive disk.I.e. drive disk needs to turn clockwise several circles to drill, then during another mistake
A few circle withdrawing chip removals of pin reversion, then the drilling that turns clockwise.Need to convert the steering of drive disk in boring procedure repeatedly, and it is hand
The driving force of brill derives from human arm muscle, and the hand direction of frequent changes causes arm muscles different with joint force direction,
Easily cause hand drill deflection.And the hand action of frequent changes, muscle can not be formed muscle memory, cause hand to shake speed
It is unstable, influence drilling quality and efficiency.

After bolt is removed, rotating shaft is slided along rotating shaft buckling groove, when sliding at rotating shaft mounting hole, the dismounting of rocking arm can be realized.Just
In the installation and removal of rocking arm, and ensure that rocking arm can rotate around rotating shaft all the time in rotary course.Clutch discs and rotating shaft
Eccentric setting, when drive disk turns clockwise, rotating shaft follows drive disk to drive clutch disc spins, when clutch discs and the end of fixed disk
When face laminating is rotated, the sliding tooth of driving plate edge is engaged with driving bevel gear, and driving bevel gear rotation is driven when drive disk is rotated
Turn, driving bevel gear drives main shaft rotation, main shaft drives bit, realizes drilling.When in clutch disc spins to fixed disk
When clutch is raised, clutch is raised to be supported to clutch discs, moves axially clutch discs, and clutch discs drive rotating shaft and drive disk axially flat
Move and compression reseting spring, now, the sliding tooth on drive disk departs from driving bevel gear.With the translation of rotating shaft, drive and turn
Counter drive gear translation on axle, due between plane where plane where counter drive gear and adjustment gear it is vertical away from
Identical from the height that clutch is raised, therefore, the adjustment gear that connection is rotated on the counter drive gear and support after translation is nibbled
Close.When drive disk is rotated further, the counter drive gear that rotarily drives of rotating shaft rotates, and counter drive gear drives adjustment gear
Rotation, adjustment gear driven reversion bevel gear rotation, reversion bevel gear drives the bit on main shaft and main shaft.Due to anti-
Turn to connect by adjusting gear between bevel gear and counter drive gear, therefore, when main shaft keeps being rotated clockwise, main shaft
Steering from it is different before, realize in the reversion of drill bit, drill bit Umklapp process, scrap is exited, be easy to continue drill, prevent scrap
Block drill bit.When clutch disc spins are after clutch is raised, back-moving spring promotes drive disk, rotating shaft, counter drive gear, clutch
Disk resets, now, and counter drive gear departs from adjustment gear, and the sliding tooth on drive disk is engaged again with driving bevel gear,
Realize drilling.Drive disk is driven in the whole rotary course of rotating shaft, by the cooperation of clutch and reversing device, realizes driving
The steering of disk remains constant, without reversion manually, it becomes possible to realize the reversion withdrawing of the pulse frequency of drill bit, move back bits, by
In without change hand direction and action repeatedly, therefore muscle memory is easily formed, the rotating speed of manual rotation drive disk can
It is held essentially constant, improves drilling quality and speed.
It should be understood that the embodiment is only illustrative of the invention and is not intended to limit the scope of the invention.In addition, it is to be understood that
Read after the content of the invention lectured, those skilled in the art can make various changes or modifications to the present invention, these etc.
Valency form equally falls within the application appended claims limited range.
