Description
Technical field
The utility model is related to a kind of time rib machine automatically, belongs to technical field of automation equipment.
Background technology
Because processing problems, iron filings burr do not remove and subsequent heat treatment deformation etc. reason all can caused by screw thread it is bad.This is asked
Topic is difficult fundamentally to solve, and it is essential work to reprocess, and current, and common repair method is that operator directly uses silk
Cone returns screw thread again by hand, and the method is extremely inefficient, if finding, it is necessary to which spiral shell could be returned by first fixing finding
Line, very uneconomical practicality.
Utility model content
In view of above the problem of exist, the purpose of this utility model there is provided a kind of clever structure, easy to operate, automatic
Change time rib machine automatically of efficiency high and safety.
The utility model solves the technical scheme that its technical problem used；It is a kind of to return rib machine automatically, include bottom
Seat, bearing, motor, rubber wheel, deceleration force amplifier commutator segment, back-moving spring, screw tap live spindle, described deceleration force amplifier commutator segment
There is two panels, be separately fixed in screw tap live spindle, suitable distance is kept between two panels, screw tap live spindle is pacified by bearing
On base, its one end installs back-moving spring, between deceleration force amplifier commutator segment and base, keeps certain under nature
Compression pretension, the other end be equipped with screw tap or bolt die, when screw tap live spindle rotate drive screw tap work；Motor is fixed on bottom
On seat, the rubber wheel of driving is housed on motor shaft, and between two panels deceleration force amplifier commutator segment.
It is above-mentioned to return rib machine automatically, during idle running, a piece of deceleration force amplifier commutator segment under the effect of back-moving spring precompression with
Rubber wheel is contacted, under motor driving, the rotation of deceleration force amplifier commutator segment, because return spring precompression is small, the torque very little of output.
Above-mentioned returns rib machine automatically, and when returning screw thread, workpiece screwed hole is withstood screw tap head, screw tap live spindle by operator
And deceleration force amplifier commutator segment under workpiece thrust to another Slideslip, the pressure between deceleration force amplifier commutator segment and rubber wheel adds
Greatly, output torque increases, and screw tap rapidly enters workpiece, after screw tap is attacked on earth, and output torque is maximum, and hand can be felt, now
Workpiece is reversely drawn, deceleration force amplifier commutator segment reverse slide is driven, until another deceleration force amplifier commutator segment is contacted with rubber wheel, completed
Commutation, now screw tap reversion, is screwed out out of workpiece, and back-moving spring resets deceleration force amplifier commutator segment, completes a working cycles.
It is above-mentioned to return rib machine automatically, the big I of driving force by change rubber take turns to deceleration force amplifier commutator segment center away from
From being adjusted, it can also be changed by the thrust size of offhand.
It is above-mentioned to return rib machine automatically, by frictional force transmit power can prevent because driving force is excessive when human hand can not hold
Workpiece and cause danger, it is safe and reliable, hand unclamp workpiece when driving force diminish automatically.
The beneficial effects of the utility model be to provide it is a kind of return rib machine automatically, to eliminate the scarce of institute's use technology at present
Fall into, have the following advantages that：
1. clever structure, easy to operate, the design meets human factor engineering and the custom of workman, when workpiece is pushed away forward, silk
Coning enters, when pulling back, and screw tap is screwed out；
2. operating efficiency is high, motor driving, speed is not required to clamping and fixed far above manual operations, and workpiece；
3. safe and reliable, during idle running, deceleration force amplifier commutator segment is gently contacted with rubber wheel, and screw tap rotating torque very little works as work
When making, motor transmits power drive screw tap by frictional force and worked, and to be the power size that workpiece is drawn, pressed by operator determine frictional force
Fixed, when motor driving force is excessive, human hand can not hold workpiece, and the power that people pulled, pressed workpiece reduces, and frictional force reduces, and subtracts
Skidded between fast reinforcement commutator segment and rubber wheel, so as to reduce the power of screw tap, it is to avoid produce dangerous；Motor is without frequently just
Reversion, it is not easy to burn motor.

Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail, but
It is not the limitation to the utility model protection domain.
Reference picture 1, Fig. 2, a kind of time rib machine automatically described in the utility model, include base 1, bearing 2, slowing down increases
Power commutator segment 3 has two panels, in screw tap live spindle 4, and screw tap live spindle 4 is positioned on base 1 by the dress of bearing 2, and
It can slide axially, the one end of screw tap live spindle 4 is equipped with back-moving spring 5, reset deceleration force amplifier commutator segment 3 in idle running, with electricity
The rubber wheel 9 of machine 8 is disengaged, it is ensured that safety, screw tap 6 is arranged in screw tap live spindle 4, and screw tap live spindle 4 drives screw tap 6 to revolve
Turn, screw tap 6 is moved workpiece 7 in the direction of arrows, and screw thread is reprocessed.
Operation principle of the present utility model and specific works mode are as follows：
A kind of time rib machine automatically described in the utility model, drives screw tap rotation to return workpiece screw thread by motor
Repair, screw tap is rotated without human hand, efficiency is very high.During idle running, two panels deceleration force amplifier commutator segment 3 is in the precompressed masterpiece of back-moving spring 5
In an intermediate position under, wherein a piece of gently contact with rubber wheel 9, motor 8 drives rubber wheel 9 to dally, and screw tap 6 does not work；Return
During screw thread, operator pushes the screwed hole of workpiece 7 to screw tap 6 in the direction of the arrow, and screw tap live spindle 4 is under the thrust of workpiece 7
To another Slideslip, a piece of deceleration force amplifier commutator segment 3 therein is pressed on rubber wheel 9, and rubber wheel 9 passes through frictional force between the two
Driving deceleration force amplifier commutator segment 3 is rotated, so as to drive screw tap 6 to shoot in the screwed hole of workpiece 7, screw thread is reprocessed；
When workpiece 7 is exited, operator draws workpiece 7 to arrow opposite direction, and screw tap live spindle 4 follows workpiece 7 to slide, another
Piece deceleration force amplifier commutator segment 3 is pressed on rubber wheel 9, is reversely rotated by frictional force drives screw tap live spindle 4, realizes commutation,
Workpiece 7 is exited from screw tap 6；
The big I of driving force is adjusted by changing rubber wheel 9 to the distance at the center of deceleration force amplifier commutator segment 3；
【Embodiment】
The internal thread of workpiece 7 is reprocessed, and screw tap 6 is fixed in screw tap live spindle 4 first, and regulation rubber wheel 9 increases to slowing down
The distance at the center of power commutator segment 3 changes the direction of rotation of electric machine main shaft, makes the rotation direction of screw tap 6 to reach the suitable operational forces of screw tap 6
It is consistent with the thread rotary orientation of workpiece 7, the custom of people is conformed to, is pushed away forward, screw tap 6 is screwed in, and is pulled back, screw tap 6 is screwed out, during work, will
The screwed hole of workpiece 7 pushes 6, screw tap to, and screw tap 6 screws in workpiece 7, the screw thread of workpiece 7 reprocessed, to after extreme position, backward
Draw, screw tap 6 is screwed out, complete screw thread reclamation work.
