Abstract

The invention discloses an electric hand vice, which comprises a main shaft motor, a planetary gear, a worm reciprocating gear shaft, a knob gear ring, a knob motor and a telescopic handle, wherein the two working strokes are controlled to be integrated with trigger switch operation, a forceps mouth part has an opening and closing clamping stroke, and simultaneously, the tightening and loosening of the forward and reverse rotating forceps mouth can be operated. The handle is internally provided with a telescopic length, so that short-distance operation is increased for high-temperature radiation workpieces or short-distance operation due to insufficient space distance.

Description

Electric hand vice

Technical Field

The invention relates to a hardware electric tool, in particular to the field of electric hand pliers.

Background

The pliers which are often used in engineering operation and daily mechanical maintenance and are held by one hand are opened, closed and clamped by one hand, more than two working strokes are required to be operated, the pliers are particularly laborious, are operated for a long time, are low in efficiency and are fatigue to personnel.

Disclosure of Invention

In order to solve the existing problems, the planetary gear is used for increasing the biting force of the pliers, and meanwhile, the worm gear shaft, the torque-variable gear and the pliers teeth are distributed in one transmission direction, so that the space of mechanical distribution is saved, and the space of mechanical transmission of the pliers mouth is effectively optimized. The forceps mouth part composed of the handle 7 and the handle 8 is fixed on a rotary gear ring 4, a rotary motor 5 is independently installed, the operation of a positive knob and a negative knob is realized, two working conditions are not influenced by each other, and two stroke operation controls are integrated with a trigger switch.

The clamp teeth 7 and the clamp claws 8 are two symmetrical clamp mouths, the torque-variable gear 6 is driven by meshing, the two clamp claws are two semicircular gears which are concentrically overlapped, the two clamp claws are opened to the maximum angle position, and the worm reciprocating gear shaft 3 of the spindle motor synchronously rotates to the steering switching position to complete the reciprocating stroke of opening and closing.

The telescopic rod 13 and the electric telescopic shaft arranged in the handle 12 are combined into a handle with a telescopic length, and the short-distance operation of increasing the handle for high-temperature radiation workpieces or short-distance insufficient space is realized.

Drawings

Fig. 1 is a schematic structural view of the present invention.

Fig. 2 is a view showing the jaws open and closed.

Fig. 3 is an illustration of the handle telescoping.

In the figure, a brushless motor (1), a planetary gear (2), a worm reciprocating gear shaft (3), a knob gear ring (4), a knob motor (5), a torque conversion gear (6), a clamp gear (7), a clamp claw (8), a lithium battery (9), a trigger switch (10), a locking switch (11), a handle (12), an expansion link (13) and an electric expansion shaft (14).

Detailed Description

In the first embodiment, as shown in fig. 2, when the handle is held by one hand during iron wire binding, the trigger switch is pressed, the jaw is opened and then pressed again, the jaw is closed, the stroke is used for clamping the iron wire, the left and right sides of the integrated switch are opened, the motor of the knob jaw starts to work, and the iron wire is turned to the maximum tightness leftwards or rightwards. And (5) realizing binding. The two working actions are controlled in an integrated manner, only the flexible control of the forefinger is needed, and the strength of the arm is concentrated on the handle to be held tightly, so that the design of the human engineering is met.

In the second embodiment, as shown in fig. 2, a screw is turned on, the integral switch is pressed, the jaw is closed and contacted with the screw head, locking is needed at the moment, the locking switch is pressed by a mother and a son of an operator, basic clamping of ordinary pliers is realized, and screwing and loosening of the screw are realized by controlling forward and reverse rotation of the jaw through a trigger switch.

In the third embodiment, as shown in fig. 3, the short-distance operation of compensating the handle is performed by the processing center of the smelting or heat treatment workshop for the workpiece radiated at high temperature or the short-distance operation of repairing the narrow space of the workshop, and the long handle and the short handle are extended and contracted by pressing an 11-switch.

In practical application, the capacity of the battery and the total weight of the electric pliers are within the ergonomic design range, and under the condition that the quality of the pliers is not changed, the capacity of the battery is increased, the battery is overweight, the arm is fatigued, the capacity of the battery is proper, and a plurality of batteries are replaced and combined for use. Meanwhile, the standby battery and the charger can continuously replace the battery, and the battery can be charged and used at the same time or a plurality of batteries can be standby, so that the use efficiency is fully improved.

The above-mentioned embodiments describe the technical solutions and advantageous effects of the present invention in detail. The above embodiments are not intended to limit the present invention, and equivalent variations are within the scope of the present invention.
