Abstract

The utility model discloses a charging-type electric wrench which comprises a battery pack (1), a speed control switch (2), a pushbutton (3) rotating forwardly and reversely, a shell body (4), a motor (8), a center cover (12), a transmission mechanism (13), a head shell (14), an impact mechanism (15) and an output shaft (16). A motor rear fixing seat (6) is arranged on the end face of the tail portion of the motor (8). A motor fixing frame (5) corresponding to the motor rear fixing seat (6) is arranged on the shell body (4). The motor rear fixing seat (6) is fixed on the motor fixing frame (5) through a motor rear rubber pad (7). At least on motor rubber ring (9) is arranged on a body of the motor (8) in a sleeved mode. A groove in the reverse side of the motor rubber ring (9) is buckled on a protruding rib of the shell body (4). A motor front rubber ring (10) is arranged between the end face of the head portion of the motor (8) and the end face of the center cover (12) in a sleeved mode. Due to the structure, the charging-type electric wrench has the advantages of being simple and reasonable in structure, easy to assemble, convenient to operate, use and carry, good in shock absorption effect and free of restriction by a working place and a power supply.

Description

The charged electric spanner

Technical field

The utility model relates to a kind of electric tool, particularly a kind of charged electric spanner.

Background technology

Tradition dismounting or screw, bolt or nut are installed are all adopted manual operations, inefficiency, labour intensity are big, can not satisfy far away and install and the requirement of maintenance.But along with the development of society, the assembling of screw, bolt or nut also develops towards the mechanization direction, and electric wrench is exactly a kind ofly to be used for dismantling or the electric tool of tighten the screws, bolt or nut.But existing electric wrench in use has the following disadvantages: the one, need AC power in the working site, need long in tow power line during use, do not have the place of AC power just can not use, bring inconvenience when operation especially in the open air or work high above the ground.The 2nd, owing to produce high-intensity impulsive torque, this impulsive torque produces great vibrations to machine to electric wrench in operation process, and the long-time manual working of operating personnel will be numb, feel like jelly, and influences normal operation.The 3rd, middle cover and housing adopt screw to fix, and are subjected to the influence of side's machining accuracy easily and can't assemble or assemble the back complete machine and mal-operation occurs, assemble loaded down with trivial details, the required precision height.For this reason, many manufacturers and knowledgeable people develop and manufacture experimently at the problems referred to above, but do not find comparatively reasonably solution so far as yet.

Summary of the invention

In order to overcome the problems referred to above that existing electric wrench exists, the purpose of this utility model provide a kind of simple and reasonable, required precision is low, assembling is easy, manipulate and easy to carry, good damping effect, be not subjected to the charged electric spanner of workplace and power limitations.

The technical scheme that its technical problem that solves the utility model adopts, it comprises power brick, speed-regulating switch, rotating push button, housing, motor, middle cover, transmission mechanism, head capsule, beater mechanism, output shaft, the tail end face of described motor is provided with holder behind the motor, housing be provided with motor after the corresponding motor fixing frame of holder, behind the motor holder by motor after rubber blanket be fixed on the motor fixing frame; At least be arranged with a motor rubber ring on the described motor fuselage, the negative grooves of motor rubber ring is buckled on the convex tendon of housing; Be arranged with the preceding rubber ring of motor between the end face of described motor head end and middle cover.

The ring gear junction of both sides and transmission mechanism is provided with motor rubber fixed mount before and after the described motor head end.

Described housing is provided with fixedly cushion block of the housing that matches with middle cover retaining muscle, middle cover pack into the housing back casing fixedly cushion block prop up middle cover and keep off muscle.

After adopting said structure, following advantage and effect are arranged compared with the prior art:

The one, because owing to adopt the power brick DC power supply, solved existing electric wrench working site AC power and when work problem of long power line in tow must have been arranged, can both work whenever and wherever possible, be not subjected to the restriction of workplace, carry simple and conveniently, be particularly suitable for field work or work high above the ground.

The 2nd, owing to rubber ring before rubber blanket after before and after motor, being provided with motor and the motor, on the motor fuselage, be arranged with the motor rubber ring, the impulsive torque that in operation process, produces, rubber ring and motor rubber ring can reduce vibration before back rubber blanket, the motor, the complete machine oscillation amplitude is little, the operating personnel is manual working for a long time, and the setting of rubber fixed mount both can reduce vibration, can guarantee stability of transmission again.

The 3rd, because housing is provided with fixedly cushion block of the housing that matches with middle cover retaining muscle, the casing rigidity height, the quality of fit requirement is low, and assembling speed is fast, and is simple and convenient.

1 power brick wherein, 2 speed-regulating switch, 3 rotating push buttons, 4 housings, 5 motor fixing frames, holder behind 6 motors, rubber blanket behind 7 motors, 8 motors, rubber ring before the 9 motor rubber rings, 10 motors, 11 housings are cushion block fixedly, 12 middle cover, 13 transmission mechanisms, 14 head capsules, 15 beater mechanisms, 16 output shafts.

The specific embodiment

Illustrated in figures 1 and 2, specific embodiments for the utility model charged electric spanner, it comprises power brick 1, speed-regulating switch 2, rotating push button 3, housing 4, motor 8, middle cover 12, transmission mechanism 13, head capsule 14, beater mechanism 15, output shaft 16, the tail end face of described motor 8 is provided with holder 6 behind the motor, housing 4 be provided with motor after holder 6 corresponding motor fixing frames 5, holder 6 is fixed on the motor fixing frame 5 by rubber blanket behind the motor 7 behind the motor; Be arranged with two motor rubber rings 9 on described motor 8 fuselages, the negative grooves of motor rubber ring 9 is buckled on the convex tendon of housing 4; Be arranged with the preceding rubber ring 10 of motor between the end face of described motor 8 head end and middle cover 12; The ring gear junction of both sides and transmission mechanism 13 is provided with motor rubber fixed mount 17 before and after described motor 8 head end; Rubber blanket 7, motor rubber ring 9, the preceding rubber ring 10 of motor and motor rubber fixed mount 17 play buffering, vibration damping and stabilization behind the motor.Described housing 4 is provided with fixedly cushion block 11 of the housing that matches with middle cover 12 retaining muscle, middle cover 12 pack into housing 4 back casings fixedly cushion block 11 prop up middle cover 12 and keep off muscle, can reduce assembly process, the quickening assembling speed.

The above; being an embodiment of the present utility model, is not that the utility model is made any pro forma restriction, is not breaking away from the technical solution of the utility model basis; the simple modification of having done, equivalent variations or modification all fall into protection domain of the present utility model.
