Abstract
The utility model provides an AC power supply handheld tool which comprises a high voltage DC motor which is provided with a motor shaft and a rotating shaft which is driven by the motor shaft, wherein an insulating connecting part is arranged between the motor shaft and the rotating shaft. In the utility model, the size of a handheld tool body is further reduced through the use of the high voltage DC motor; meanwhile, the insulating connecting part is arranged between the motor shaft and the rotating shaft, and provided insulation enables the single-insulating motor to meet double-insulating requirements. Besides, as the existing AC power supply class handheld tool of the prior art adopts an AC series motor, the motor holding position of the tool body is wider than that of the DC class tool body, and the hand holding feeling is not as good as that of the DC class. However, the AC power supply handheld tool of the utility model can obtain the same hand holding feeling with the DC class tool through the use of the high voltage DC motor.
Description
Technical field
The utility model relates to a kind of handheld tool, particularly relates to a kind of handheld tool of Alternating Current Power Supply.
Background technology
AC power class handheld tool is because use exchanges series excited machine, so fuselage motor grip position is more roomy than direct current class fuselage, and gripping feel does not have the direct current class good.Multi-purpose tool is a kind of handheld tool commonly used, and multi-purpose tool is to rely on drive part (motor), running part and output to transfer torque to the work that realizes on the working head.Motor generally has series excited machine and direct current generator, and series excited machine is powerful but volume is big, can not work long hours but the direct current generator volume is little.The volume that the HVDC motor has d.c. motor is the AC power continued power simultaneously.
Summary of the invention
Main purpose of the present utility model provides a kind of handheld tool of Alternating Current Power Supply, makes littleizationr of multi-purpose tool fuselage by using the HVDC motor, and can satisfy two insulating requirements.
For achieving the above object, the utility model adopts following technical scheme:
A kind of handheld tool of Alternating Current Power Supply comprises: the HVDC motor with motor shaft reaches by the motor shaft rotating shaft driven, wherein: be provided with the insulation coupling part between described motor shaft and the rotating shaft.
Described insulation coupling part comprises a shaft coupling.
Described shaft coupling is made by insulating materials.
Described shaft coupling one end forms porose, and the hole is built-in with a connector that can not circumferentially rotate with described motor shaft.
Described connector is made by metal material.
One end of described shaft coupling is formed with and the sealed shape locking part that is connected of described rotating shaft shape.
Described shape locking part is configured to corrugated outer circumference surface.
Described shaft coupling is installed with fan outward.
Described rotating shaft is arranged with capacity eccentric bearing outward.
Also comprise a shift fork, an end of described shift fork contacts with the outer circumference surface of described bearing, the output shaft fixed connection of the other end and instrument.
By adopting above technical scheme, can realize following useful technique effect:
The utility model makes littleizationr of handheld tool fuselage by using the HVDC motor, and the insulation that the while shaft coupling provides makes single insulated motor satisfy two insulating requirements.
In addition, AC power class handheld tool in the prior art is because use exchanges series excited machine, so fuselage motor grip position is more roomy than direct current class fuselage, and gripping feel does not have the direct current class good.And the utility model uses high voltage direct current motor can obtain the gripping feel the same with direct current class instrument.
Description of drawings
Fig. 1 is the internal structure schematic diagram of the handheld tool of the utility model Alternating Current Power Supply, wherein with a kind of multi-purpose tool as preferred embodiment;
Fig. 2 is the explosive view of motor among Fig. 1, eccentric shaft and shaft coupling;
Fig. 3 is each parts connection diagram among Fig. 2;
Fig. 4 is that shaft coupling is connected stereogram with eccentric shaft.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Shown in Fig. 1 to 4, multi-purpose tool comprises casing 2, and power line 1 has been dragged in casing 2 rear ends, is provided with motor 3 in the casing 2, shaft joint 4.Wherein shaft joint 4 is fitted on the motor shaft 31, and fan blade 5 is fixed on the shaft joint 4.Shaft joint 4 is connected by spline with eccentric shaft 6 gaps.Eccentric shaft 6 rotates the capacity eccentric bearing 7 that drives on it and rotates, and capacity eccentric bearing 7 drives the shift fork 8 that cooperates with its periphery and swings back and forth, and shift fork 8 drives with its stationary output shaft 9 and swings back and forth, thus realization work output.
Wherein motor 3 is HVDC motors, and its power supply is an AC power supplies, is single insulated motor.Shaft joint 4 is made up of two parts, comprises metal embedded component 41, and its endoporus closely is connected with motor shaft 31, realizes the moment of torsion transmission.Shaft joint 4 matrixes are made of plastics, and front end has spline tooth 42.Eccentric shaft 6 ends have splined hole 61, and its shape is corresponding with 42, make shaft joint 4 be contained in eccentric shaft 6 holes, and transmit moment of torsion by the cooperation of spline tooth 42 and splined hole 61.Because shaft coupling 4 matrixes have wrapped up metal embedded component 41, metal embedded component 41 and eccentric shaft 6 are kept apart, shaft coupling 4 is ambroins simultaneously, so can play the effect of insulation.
