Description

Trigger electric wrenching machine

The utility model belongs to a kind of electric plate shearing machine, is applicable to the bolt in manufacturing, the repair industry, the dismounting of nut, especially can be with car field work.

The described electrical impact spanner of Chinese patent application bulletin CN2095743U, gas passage and sealing device and centrifugal valve are equipped with in inside, connect impulse pin with the fling rammer centrifugal valve, drive the plate spindle nose, come the dismounting nut, thereby complex structure, the cost height.

The purpose of this utility model provides the impact electric plate shearing machine that a kind of dismounting industry is used, and it can easily make impulse pin stretch out from fling rammer or withdraw, and reaches the dismounting nut.

The utility model is to realize like this, the impact electric plate shearing machine of forming by motor 1, fling rammer 2, plate axle 3 and shell 4, one end of the motor shaft 5 of motor 1 embeds in the fling rammer 2 of a side and is fixedly connected, axial coil along motor shaft 5 is equipped with movable rod 6, the impulse pin 7 that connecting rod 6 passes in motor shaft 5 one ends and the fling rammer 2 is connected, the rear portion of impulse pin 7 places spring groove 8, and connecting rod 6 other ends stretch out outside the motor shaft 5 and link to each other with bearing handle 9.

The utility model when motor rotates, is decontroled connecting rod owing to adopted connecting rod pulling-down impulse pin to return in the fling rammer, and the pin crown of the spring handle impulse pin of spring groove goes out fling rammer and links to each other with the plate axle, and the impulse pin shock plate axle of rotation reaches the dismounting nut.Thereby the utility model is compared with prior art, has following advantage:

1, motor speed all can be worked in per minute 6-9 thousand commentaries on classics scopes.

2,12 volts or 220 volts AC power work of available less storage battery, power saving, safe and reliable.

3, moment of torsion is 55 kilogram-metres-90 kilogram-metres, and moment of torsion is big.

4, simple in structure, volume is little, and is in light weight, and cost is low, easy to carry.

Below in conjunction with embodiment and accompanying drawing the utility model is elaborated:

Fig. 1 is the structural representation of impact electric plate shearing machine.

Fig. 2 cuts open schematic diagram for the A-A of Fig. 1.

By motor 1, fling rammer 2, the impact electric plate shearing machine that plate axle 3 and shell 4 are formed, by as shown in Figure 1, one end of motor shaft 5 embeds in the fling rammer 2 of a side and is fixedly connected, motor shaft 5 can be connected by hexagonal draw-in groove 16 with fling rammer 2, by shown in Figure 2, a movable rod 6 is housed on the axis of motor shaft 5, connecting rod 6 can be with motor shaft 5 runnings, connecting rod 6 one ends link to each other with the impulse pin 7 of energy advance and retreat activity in the fling rammer 2 by pin 14, be that impulse pin 7 is placed on the size dimension groove 17 bigger than impulse pin 7, the size of groove 17 can make impulse pin 7 pin 13 stretch out fling rammer 2 and withstand on the plate axle 3, thereby impulse pin 7 and sell 14 and can and in groove, advance and retreat with connecting rod 6 pulling, impulse pin 7 rear portions are stuck in the spring groove 8 by ladder 12 and do not skid off, spring 10 1 ends in the spring groove 8 withstand on the plug 11, the other end withstands on impulse pin 7 rear portions, impulse pin 7 is under the elastic force effect of spring 10, can stretch out fling rammer 2 withstands on the plate axle 3, the other end of connecting rod 6 stretches out outside the motor shaft 5 and links to each other with bearing handle 9, there is rubber washer 18 bearing 9 front portions of shaking hands, play cushioning effect, the rear portion has plug 19 to prevent that bearing handle 9 breaks away from connecting rod 6, and fling rammer 2 opposite sides link to each other with plate axle 3 by spin 15.During work, connect 220 volts of power supplys or 12 volts of storage batterys, bearing on the pulling connecting rod 6 shakes hands 9 earlier, the impulse pin 7 that links to each other with connecting rod 6 is withdrawn in the fling rammer 2, and do not touch mutually with plate axle 3, spring 10 savings potential energy in the impulse pin 7 compression spring grooves 8, when starting power was 300～660 watts of motors, motor 1 drove the rotational speed of the fling rammer 2 of 1.2-2.5 kilogram weight with per minute 6～9,000 commentaries on classics, and moment is decontroled bearing handle 9, under the 10 elastic force effects of 4-6 kilogram spring, the pin of impulse pin 7 13 a quick fling rammer 2 that eject drive plate axle 3, and plate axle 3 impacts nuts, at this moment stop because of impacting back plate axle, then disable motor.Spur connecting rod 6 so again impulse pin 7 is returned in the fling rammer 2, repeat so repeatedly, just can reach the dismounting nut.Thereby the utility model is simple to operate, and is easy to use.
