Abstract
The utility model relates to a vehicle-mounted electric impact wrench used as vehicle-mounted repairing tool, including motor, drive mechanism, body, end cover, output main shaft, its characterized in that: a ferrule is sleeved outside the body, a centrifuge is fixedly sleeved on the ferrule, an impact block is arranged in a closed cavity formed by the body and the end cover, two convex blocks are fixedly arranged on one side of the impact block, a spring is supported on the other side of the impact block, and an ejector rod penetrating through the body is arranged between the impact block and the ferrule; one end of the output main shaft is provided with a bidirectional hammer block corresponding to the lug of the impact block. The utility model discloses but automatic dismouting tire bolt realizes that the repair operation is automatic.
Description
The utility model relates to a kind of with the car repair outfit, be meant especially a kind of be used for assembling-disassembling bolt with the electronic bump spanner of car.
Motorist in highway way because of tire fault must in time be repaired, the situation of re-type happens occasionally.For a long time, the repairman makees dismounting tire 1/2 with manual wrench under the environment of spaciousness " work of diameter bolt is the manual labor of not only time-consuming but also effort really.
It is a kind of with the electronic bump spanner of car that the purpose of this utility model is to provide, and can automobile storage battery be power supply, and assembling-disassembling bolt is realized the automation of repair operation automatically.
The purpose of this utility model reaches as follows:
A kind of with the electronic bump spanner of car, comprise motor, transmission mechanism, body, end cap, output main shaft, it is characterized in that: at the sheathed lasso in the body outside, this lasso tightens a sheathed sedimentator, in the enclosed cavity of body and end cap formation, be provided with an impact block, one side of this impact block is installed with two projections, and opposite side holds a spring, is provided with the push rod that passes body between impact block and described lasso; The corresponding two-way mallet piece that is provided with the projection of impact block of one end of this output main shaft, the other end of output main shaft passes in the enclosed cavity of body and end cap formation.
The purpose of this utility model can also following mode reach: described it is characterized in that: the periphery wall of described impact block is provided with groove, is equipped with straight pin in the groove with the electronic bump spanner of car, and this straight pin then is fixed on the end cap inboard.
Effect of the present utility model is:
1, the repairman never needs complicated pneumatic plant system when this instrument of use, as long as the power line of instrument is connected on output place of automobile batteries 12V power supply own, then, the gauge tap of pressing instrument just can be finished whole work of assembling-disassembling bolt easily, never effort.Thereby, realized the repair operation automation, and equipment being simple, volume is little, and is portable, time saving and energy saving.
2,,, rotate together and can drive bolt so the instantaneous meeting that is coupled at impact block and output main shaft produces powerful moment of torsion because body assembly of the present utility model has stored huge inertial impact force when just beginning to rotate.Do not have angular force extremely when producing the mechanical action of wrenching, high speed rotating is balance more, and the moment of torsion of output also doubles to increase.
Illustrate:
Fig. 1 is a combining structure cutaway view of the present utility model.
Fig. 2 is a structure member exploded view of the present utility model.
Fig. 3 is in the released state schematic diagram for impact block of the present utility model and output main shaft.
Schematic diagram when Fig. 4 is impact block of the present utility model and output spindle coupled.
The utility model will be described in further detail as follows in conjunction with the accompanying drawings: see figures.1.and.2, the utility model comprises motor 1, body 9, end cap 12, output main shaft 15, motor 1 adopts permanent magnet DC motor, 12 volts of power supplys by automobile provide power, the transmission mechanism that motor 1 is formed by pinion 2 and gear wheel 4 drives body 9 and rotates, the sheathed lasso 7 in body 9 outsides, lasso 7 tightens a sheathed sedimentator (not shown), sedimentator is by pull bar, extension spring, centrifugal, members such as fixed head are formed, when reaching the setting rotating speed, because centrifugal of centrifugal action will move automatically laterally and drive lasso 7 is outwards mobile together.Because of sedimentator on sale in market, so will not describe in detail.Body 9 is connected with end cap 12 and forms an enclosed cavity 24, the left end of output main shaft 15 is located in this enclosed cavity 24, and by ball bearing 18,22 support location, the right-hand member of output main shaft 15 is piercing in the outside of end cap 12, can adorn the sleeve of different size on the square head of its right-hand member, so that tighten or looser a bolt or nut.Be provided with an impact block 10 in enclosed cavity 24, the impact block periphery wall is established 3 grooves, is equipped with straight pin 20 in the groove, and straight pin 20 1 ends are fixed on end cap 12 inboards, makes body 9 can drive impact block 10 and rotates together.Straight pin 21 plays the slideway effect when impact block 10 is reciprocating.The left side of impact block 10 is installed with two projections 101,102, and the right side of impact block 10 holds a spring 19, and the left side of impact block 10 is then held by push rod 8, and push rod 8 passes body 9 and holding lasso 7 with its other end.At the left end of output main shaft 15 and the projection 101 of this impact block 10,102 correspondences are installed with two-way mallet piece 151,152, in conjunction with reference to Fig. 3, Fig. 4, after motor 1 begins to rotate, body 9 will drive sedimentator and lasso 7, impact block 10 rotates thereupon, and output main shaft 15 does not rotate, after reaching the rotating speed of setting, body 9 and assembly thereof have obtained enough stored energy power-inertial impact forces, sedimentator will be moved to the left automatically, this moment, lasso 7 was also to moving to left, so impact block 10 can be to moving to left under the elastic force effect of spring 19, make the projection 101 of impactor 10,102 suddenly with the two-way mallet piece 151 of output main shaft 15,152 couplings, therefore export the unexpected fast rotational of main shaft 15 meetings, produce great moment of torsion output suddenly, be used to tighten or loosen nut.Oiliness bearing 3 is set in the body termination can store lubricating oil, and oiliness bearing 14 is sheathed on the output of output main shaft 15, plays lubricated and the effect of reducing friction.The positioning action that 21 bodies 9 of straight pin and end cap are 12.Owing to adopt the design of two-way mallet piece and projection coupling, body assembly balance more when high speed rotating, producing at the output main shaft does not have angular force extremely when powerful moment of torsion is exported.
