Abstract
The utility model relates to an electric trigger, which is a tool mainly used for screwing or handling various screws and screw caps particularly the screw caps on a motor vehicle. The utility model comprises a vehicle frame (4), a vehicle wheel (15), a vehicle wheel frame (5), an electric machine (11), an electric machine switch (14) and an impact clutch (13). the output end of the impact clutch is connected with a plate head (12), and is also provided with a conical tooth retarding mechanism (2) and a spline shaft (3). A transmission mechanism (1) is arranged between the electric machine shaft and the conical tooth retarding mechanism; the conical tooth retarding mechanism (2) is connected with the impact through the spline shaft. The electric trigger has the advantages of small size, little occupation area, easy and convenient operation, and labor saving.
Description
The utility model relates to a kind of Electric trigger, is a kind ofly to be mainly used in degree of tightness or to load and unload the particularly instrument of the nut on the power actuated vehicle of various screw nuts.
Trigger commonly used at present mainly is the pneumatic trigger that is provided with impact clutch.This trigger need be equipped with Air compressor, and its work meeting is subjected to the influence of Air compressor air pressure height; In addition, this equipment volume is big, floor area is many, and operation is trouble also, needs operating personal to bear a heavy burden and operates.
The purpose of this utility model provides a kind of Electric trigger, this trigger configuration compactness, and volume is little, and floor area is few, and easy to operate.
The purpose of utility model realizes by following mode.
Electric trigger, comprise vehicle frame, wheel, vehicle wheel frame, motor, motor switch and impact clutch, the mouth of impact clutch connects wrench, also be provided with awl tooth speed reduction gearing and castellated shaft, between motor shaft and the awl tooth speed reduction gearing transmission device is set, is connected by castellated shaft between awl tooth speed reduction gearing and the impact clutch.
If the nut of degree of tightness is the autobody sheet nut of riding, the state that vehicle frame can be kept flat is pushed into needed position; If turn-knob is the motor tire screw nut, then vehicle frame can be erected, utilize front vehicle wheel that car is pushed into needed position.Corresponding sleeve is installed on wrench, and is made sleeve entangle nut; Handle motor switch, make motor shaft direction rotation on demand, motor shaft drives impact clutch work by transmission device, awl tooth speed reduction gearing and castellated shaft, and impact clutch rotates by the wrench drive sleeve or makes to be interrupted impact type and rotate, thereby nut is tightened or pine is unloaded.
This Electric trigger that the utility model provides not only compact conformation, volume is little, in light weight, floor area is few, and the operation simple and convenient, laborsaving, can effectively reduce labour intensity.In addition, also have dual-use (nut), advantages such as speed is fast, efficient is high, safety performance is good, fault rate is low, long service life but degree of tightness tire nut and steel plate are ridden.Compare with pneumatic trigger, do not need to be equipped with Air compressor, work is not subjected to the influence of air pressure height, does not need operating personal to bear a heavy burden and handles, 1/5th of the not enough pneumatic trigger of floor area.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1 is the structural representation of the Electric trigger that provides according to the utility model, and accompanying drawing 2 is birds-eye vieies of accompanying drawing 1.
Electric trigger as shown in drawings, comprise vehicle frame (4), wheel (15), vehicle wheel frame (5), motor (11), motor switch (14) and impact clutch (13), the mouth of impact clutch connects wrench (12), also be provided with awl tooth speed reduction gearing (2) and castellated shaft (3), between motor shaft and the awl tooth speed reduction gearing transmission device (1) is set, is connected by castellated shaft between awl tooth speed reduction gearing and the impact clutch.
As shown in drawings, awl tooth speed reduction gearing (2) mainly is made of two initiative taper generating gears, a passive cone gear and a transmission shaft, two initiative taper generating gears are located on the transmission shaft, passive cone gear is located between two initiative taper generating gears, and be interlocking pattern, one end of castellated shaft (3) is enclosed within the axial trough of passive cone gear, and the other end is enclosed within the axial trough of impact clutch.The housing of awl tooth speed reduction gearing and impact clutch is fixed on the vehicle frame.
As shown in drawings, transmission device (1) is made of two gears that are interlocking pattern, and one is located on the motor shaft, and another is located on the transmission shaft of awl tooth speed reduction gearing.
As shown in drawings, four wheels are installed on the vehicle frame, comprise two front vehicle wheels and two rear wheels, front vehicle wheel is installed on the front truck wheel carrier, and rear wheel is installed on the rear wheel frame, and the rear end of vehicle frame is provided with handle (8).Vehicle frame can keep flat, and also can erect, and utilizes four wheel walkings when keeping flat, and utilizes two front vehicle wheel walkings when erecting.
As shown in Figure 2, vehicle wheel frame (5) is supported on the bolster (6) that is located on the vehicle frame, and lifting spring (7) is set between vehicle wheel frame and vehicle frame or the bolster.The height of vehicle frame can be regulated like this, in the time of can regulating vehicle frame and keep flat and erect wrench apart from the distance between the ground, thereby be convenient to combination between wrench and the nut, and can adapt to the nut of differing heights and different working environments.
Claims (4)
