Abstract
A novel electric spanner utilizes electricity as energy source and is high in torque outputted by variable speed of a gearbox and simple, convenient and practical to use. The electric energy source of the electric spanner is very common, such as car generators and accumulators for vehicular electric spanners. The electric spanner is small in size and convenient to carry. The electric spanner comprises a motor and a gearbox which are integrated, forward and reverse halt on-off switch controls forward or reverse rotation, rotation speed of the motor passes the gearbox and slows down as the torque increases to rotate a screw, and the gearbox is provided with a handle. For example, during screwing a wheel hub, the handle fastens on another screw of the hub. The gearbox cannot rotate, and only an output shaft of the gearbox is provided with a sleeve head to rotate the screws.
Description
Technical field:
The present invention relates to the instrument of dismounting machinery.It is the instrument utilizing electricity to be the energy.A new electric spanner, it rotates with motor, comes torque nut or screw instrument spanner by speed changer.Especially the advantage that torsion is large.
Background technology:
Current known spanner, some spanners directly twist with hand the spanner wind big gun rotation had and twist (it needs to be furnished with special air pump, compressor)
The shortcoming of known spanner is above: the spanner directly twisted with hand, the shortcoming that torsion is little.With the spanner of wind big gun twisting, the air pressure that it needs and the very large shortcoming of air-flow, or the shortcoming of the scarce energy.
Summary of the invention:
In order to solve the shortcoming of above-mentioned spanner.The present invention utilizes electricity as a kind of new electric spanner of the energy.
The technical scheme that the present invention solves the problem is: if be used in car spanner, supplies (motor that is positive and negative, guard's valve is housed) with the electricity of the generator in automobile engine and battery.Motor rotates speed changer, speed changer has fixed handle, is stuck in and is turned round on object, and speed changer rotates the nut or screw turning round and need to turn round.
The feature that electric spanner has torsion large by speed change.
The structure of electric spanner is: have positive and negative switch and power line above motor.Motor rotation axis connects speed changer turning cylinder, and motor body and speed change body are connected (fixed motor).Speed changer output rotation axis is connected with collet head.The speed changer limit of output rotation axis head there is individual card handle, can be stuck in by the structure turned round on object.
The method used is: turn round vehicle wheel drum screw if used, and first connects the power line of electric spanner from automobile power source, refills applicable collet head at speed changer, on the turning cylinder of output.
Then turned round on screw with hand steered staying in, rotate the card handle making speed changer, be stuck on the screw on side, at use switch twist screws.
The effective effect of electric spanner is: it is stronger than using its spanner strange to use electric spanner, and be use speed changer do not hinder thread, the not effect of damaged screws.Its volume is little easy to carry, only has the volume of the half of wind big gun.
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, electric spanner is further illustrated.
1, motor body 2, speed change body 3, card handle 4, positive and negative guard's valve
5, electric wire 6, motor rotary shaft 7, speed changer rotating shaft
8, speed changer output revolving shaft 9, collet head 10, handle ring
Detailed description of the invention:
Motor body (1) and speed change body (2) link into an integrated entity, motor rotary shaft (6) and speed changer rotating shaft (7) connection of rotating speed changer rotating shaft (7), through speed changer to speed changer output revolving shaft (8), upper installing sleeve head (9).Connect positive and negative guard's valve (4) and electric wire (5) power supply again.Portable by handle ring (10), collet head (9) entangles screw, and makes card handle (3), blocks on wheel hub screw aside.Open positive and negative guard's valve (4) twist screws.
Claims (2)
1. electric spanner, motor and speed changer, speed changer card handle is connected, and turning cylinder is through speed changer, and speed change rotational sleeve head and screw, positive and negative guard's valve controls the rotating forward reversion of electric spanner.
It is characterized in that: electric spanner blocks or is fixed on to be turned round on object, utilize electricity, motor rotates through speed changer, and torsion becomes carry out greatly rotation screw and control to rotate forward reversion on power supply.
2. according to right 1, it can be gauge tap by one that electric spanner rotates forward reversion, and one is the structure controlling to rotate and reverse.
It is characterized in that: one is positive and negative switch, and one is power switch.
