Abstract

The utility model relates to a high efficient torque machinery spanner which can generate big torque and can dismount nut with high efficiency by hand. A flywheel with an impact block and a glide hoop which can make axial displacement along a main shaft and can drive the main shaft to rotate are arranged on the main shaft of the machinery spanner, and the position bulging the impact block 6 on the flywheel is near to one face of the glide hoop. The clutch handle is pulled to make the glide hoop to remove from the position with the flywheel when being operated to quickly run the flywheel, when the clutch is closed, the dynamic energy on the flywheel can be transmitted to the nut by the glide hoop driving the sleeve arranged on the front end of the main shaft, and the impact of the inertia force of the flywheel makes the nut be rapidly dismounted from the bolt or mounted tightly.

Description

High efficient torque machinery spanner

The utility model relates to a kind of machinery to be pulled, particularly a kind of when the dismounting nut manually operated efficient moment of torsion machinery pull.

Nothing more than manual, electric tool, hand-operated tools is because of various idle work loss inefficiencys in the instrument of dismounting nut, and electric tool is subjected to the pipeline restriction to dwindle use occasion.

The purpose of this utility model provides a kind of not only without the energy but also enlarge use occasion and have the high efficiency efficient moment of torsion machinery of the same high pulling torque of electric tool and pull.

The purpose of this utility model is achieved in that the flywheel that has to have protruding impact block on the main shaft, and one can drive the main shaft rotation again along main shaft axial displacement and have by the slip hoop of impact block.The effect that axial displacement makes itself and flywheel projection produce separate or merge, from the time flywheel running savings kinetic energy, the kinetic energy on the fashionable flywheel moves the sleeve fast assembling-disassembling nut of front-end of spindle by the slip band.

Accompanying drawing is the sectional side elevation of efficient moment of torsion machinery plate:

As shown in the figure, there is a nut knock-pin 2 inside of sleeve 1, the rear end of sleeve 1 is enclosed within on main shaft side's tenon 3, main shaft is fixed on the base by bearing 17,11, have by the slip hoop 15 of collision block 5 and be enclosed within on main shaft side's tenon 14, the front end of clutch handle 4 is stretched in the groove 16 of hoop 15 that slides, and the flywheel that has impact block 6 and pinion 12 is positioned on the main shaft by bearing 13, the gear wheel 8 of one end of axle 9 and pinion 12 engagements, the other end is overlapping a two-way ratchet crank handle 10.

Below with regard to the description of drawings operating process:

Sleeve 1 is inserted on the nut of (tearing open) to be installed, make handle 4 be placed on as shown in the figure " from " the position on, with acceleration driving pawl crank handle 10, by gear wheel 8, little tooth 12 makes flywheel 7 fast rotational, when flywheel 7 reaches certain rotating speed and just has certain kinetic energy, handle 4 is shifted the position of " closing " onto, the hoop 15 of sliding along main shaft to flywheel 7 displacements, being driven main shafts by impact block 5 and rotate on the hoop 15 of sliding of impact block 6 bumps on the flywheel 7.If tear nut open, flywheel 7 its inertia instant impacts that fast quick-action is changeed are enough to overcome fastening nut friction of rest power, thereby loose nut, residue inertia by flywheel 7, nut is resigned from office from bolt very like a cork, holds sleeve 1 and draws toward operating direction, push rod 2 side's of withstanding on tenons 3 and motion forward just can eject the nut of staying in the sleeve, whole process is tens seconds only, have improved operating efficiency greatly.

Claims

1, the spanner of dismounting nut, particularly a kind of manual efficient moment of torsion machinery is pulled, this machinery is pulled a flywheel 7 with protruding impact block 6 on the main shaft, but an axial displacement is arranged and can drive the slip hoop 15 that main shaft rotates at protruding impact block 6 faces, it is characterized in that: 15 one sides are being bound round in the position of protruding impact block 6 on the flywheel 7 by sliding.

2, pull according to the described machinery of claim 1, it is characterized in that: an end in the hoop 15 outer gardens of sliding is Baltimore grooves 16, and the other end is a velamen impact block 5.

3, pull according to the described machinery of claim 2, it is characterized in that being parallel surface by impact block 5 and flywheel 7.
