Outgassing nonreturn valve is equipped in mouth 75, when piston 71 moves up, the pressure of the gas on 7 top of extrusion piston bucket, 7 top of piston bucket increases
Greatly, gas is discharged by gas outlet 75；Cleaning pipe 76 is communicated on gas outlet 75.
Specific implementation process is as follows: being arranged first by be polished 8 sets of gear in the mounting post 32 in left side, and passes through support
Platform 31 is supported gear 8, and the supporting table 31 in left side moves down under the gravity of gear, therefore drives the left end of lever 2
It moves down, supporting table 31 gradually offsets with the first tapered bar 6 and push rod 72 during moving down, and gradually pushes 6 He of the first tapered bar
Push rod 72.When supporting table 31 is pressed down against push rod 72, piston 71 is moved down, and the gas of 7 lower part of extrusion piston bucket, gas passes through connection
Pipe 73 imports in the cavity 321 in mounting post 32, and is guided in tensioning air bag 33 by gas port and stomata, so that tensioning gas
Capsule 33 expands, and is tensioned the gear 8 in mounting post 32 to realize, realizes the fixation of gear 8.
Meanwhile supporting table 31 squeezes the first tapered bar 6 when moving down gradually downward so that the first tapered bar 6 gradually with the second tapered bar
61 contacts, and realize that the second tapered bar 61 is moved to the left by the cooperation of the first tapered bar 6 and the second tapered bar 61, when under 2 left end of lever
It moves to when offseting with 1 bottom of processing groove, supporting table 31 is in position as shown in Figure 2, and the second tapered bar 61 just pushes biography at this time
5 to the first spline segment of moving axis and 52 spline fitted of driven gear, the second spline segment and 51 spline fitted of drive bevel gear.Restart
Motor, motor drives driving gear 53 to rotate, by the transmission of driven gear 52 and transmission shaft 5 so that 51 turns of drive bevel gear
It is dynamic, and pass through the transmission of driven wheel of differential 42 and shaft 4, so that grinding wheel 41 rotates, realization polishes to gear 8.
After the completion of polishing, another gear 8 to be polished is placed in the mounting post 32 in the supporting table 31 on right side, according to
The supporting table 31 in lever principle, 2 left end of lever and left side moves up, to drive the gear polished 8 to move up, so that lever 2
Gradually keep the state of relative equilibrium.During supporting table 31 moves up, the power of pressure-ram 72 and the first tapered bar 6 gradually disappears
It losing, the first tapered bar 6 moves up under the action of the spring, and the second tapered bar 61 drives transmission shaft 5 to move to right under the action of the spring, so that the
One spline segment and driven gear 52, which are detached from, to be cooperated, and the second spline segment and drive bevel gear 51 are detached from and cooperate, therefore transmission shaft 5 is not sent out
Raw rotation, so that grinding wheel 41 stops operating, turns off motor.
Piston 71 also gradually moves up under the action of the spring simultaneously, so that the gas on 7 top of extrusion piston bucket, gas pass through
It cleans pipe 76 to export, and the gear 8 after 76 face of pipe is polished will be cleaned, can be realized clear to the clast progress adhered on gear 8
Reason.And piston 71 moves up so that 7 lower part air-breathing of piston bucket, will be tensioned in the gas sucker bucket 7 in air bag 33, so that opening
Tight air bag 33 stops Tension gear 8.
When gear 8 after polishing is moved to 1 top of processing groove, the gear 8 after polishing is taken out, and is located at the branch on right side
Support platform 31 moves down under the gravity of gear 8, restarts the motor on right side, is able to achieve and beats the gear 8 on right side
Mill.
For those skilled in the art, under the premise of not departing from technical solutions of the utility model, can also make
Several modifications and improvements out, these also should be considered as the protection scope of the utility model, these all will not influence this patent implementation
Effect and patent practicability.
