Abstract
The utility model relates to the technical field of clutches, particularly an energy storing electric spanner clutch. The utility model provides a clutch used between a motor output shaft and a fly hammer of an energy storing electric spanner, and aims to overcome the defect that a motor of the existing electric spanner used for dismounting screw bolts and screw caps can be easily burnt because the motor and a fly hammer of the electric spanner have the structural form of fixed connection. The clutch can prevent the state of blocked rotation from happening to the motor of the electric spanner and eliminate the hidden trouble that the motor is burnt because the occurrence of blocked rotation. The utility model comprises a body case, a mandrel, and a plurality of centrifugal blocks, wherein the body case forms the shape of a disk, the mandrel is arranged in the cylindrical cavity of the body case. The outer side face of the mandrel is provided with guide pillars which are uniformly distributed in radial direction, and the number of the guide pillars equals the number of the centrifugal blocks. The middle of the mandrel is provided with shaft holes in axial direction, and the shaft holes are matched with the output shaft of the motor. The central radial direction of the centrifugal blocks is provided with through holes which are matched with the guide pillars of the mandrel, the centrifugal blocks are sheathed on the guide pillars of the mandrel and the outer side face of the centrifugal blocks is provided with wearing pieces.
Description
Technical field
The utility model relates to the Clutch Technology field, particularly a kind of accumulation energy type electric wrench clutch.
Background technology
Existing assembling-disassembling bolt and the nut of being used for especially for the bolt on dismounting vehicle, the machine etc. and the electric wrench of nut, is the fixed connection structure form between motor output shaft on its electric wrench and the flyball.During work, the motor on the electric wrench directly drives flyball and rotates, and when flyball is in bump stall state, makes the motor on the electric wrench also produce stall; When electric wrench starts, the motor long period on its electric wrench is in the stall state, and the electric current of motor when being in the stall state be rated current 5-7 doubly, so when the motor on the electric wrench is in the stall state for a long time, cause the burn-down of electric motor on the electric wrench easily.
Summary of the invention
The utility model is at being the existing weak point that causes its burn-down of electric motor easily of fixed connection structure form between motor on the existing electric wrench that is used for assembling-disassembling bolt and nut and the flyball, a kind of accumulation energy type electric wrench clutch between the motor output shaft and flyball on the accumulation energy type electric wrench that is used for is provided, this clutch can prevent that the stall state from appearring in the motor on the electric wrench, and elimination the hidden danger that the stall state is burnt occurs because of motor.
The technical solution adopted in the utility model is finished in the following way: accumulation energy type electric wrench clutch comprises housing, mandrel, some centrifugal and with centrifugal the same number of wearing piece, housing is disk-shaped, the outer face of housing is provided with clutch output shaft, clutch output shaft is fixed on the outer face of housing, mandrel is contained in the cylindrical cavity of housing, the lateral surface of mandrel is provided with and centrifugal the same number of radially equally distributed guide pillar, at the axially middle axis hole that matches with motor output shaft that is provided with of mandrel, centrifugal intermediate radial position is provided with the through hole that matches with the guide pillar of mandrel, on the guide pillar that centrifugal is enclosed within mandrel, wearing piece is fixed on the centrifugal lateral surface.The utility model accumulation energy type electric wrench clutch device is on the accumulation energy type electric wrench time, the utility model accumulation energy type electric wrench clutch device is between the motor output shaft and flyball of accumulation energy type electric wrench, wherein, the mandrel of motor output shaft and clutch is fixed together, and the clutch output shaft of clutch and flyball one end link together.
During electric motor starting, the rotation of the mandrel of driven by motor clutch, centrifugal that is enclosed within on the mandrel guide pillar radially skids off outward under action of centrifugal force, is fixed on centrifugal wearing piece on the lateral surface and contacts with clutch housing cylindrical cavity medial surface.Raising along with rotating speed, centrifugal force increases, being fixed on centrifugal wearing piece on the lateral surface also increases applied pressure on the clutch housing cylindrical cavity medial surface, when applied pressure arrives to a certain degree, then centrifugal drives the clutch housing rotation by wearing piece, and also drives the flyball rotation thus.Because the accumulation energy type electric wrench comes transmitting torque by friction, thus no matter what state flyball is in, all can not make motor produce the stall phenomenon, thus reached the effect of protection motor.
The utility model prevents that for electric wrench provides a kind of anti-motor rotation blockage clutch the stall state from appearring in the motor on the electric wrench, eliminates motor because of the hidden danger that the stall state is burnt occurring.The utility model is particularly suitable on the electric wrench of bolt on dismounting vehicle, the machine etc. and nut.
