Technical field
The present invention relates to a kind of electric tightening machine of automotive wheel, refer in particular to a kind of dual-shaft electric screw down distance-variation apparatus.
Background technology
At present, each big automobile factory is all in widely-used multiaxis wheel electric tightening machine, and this tightening machine belongs to the wheel set of the special vehicle of special-purpose assembling, and purposes is single.When the bolt and nut that runs into different model automotive wheel assembly connects, variation because of its centre-to-centre spacing position or quantity, because the wheelbase of this tightening machine is fixed, the vehicle that can not satisfy different wheel nut reference diameter is shared, therefore have to purchase again with the supporting with it use of the tightening machine that adapts to different automobile types, increase the input of the equipment funds of the living manufacturer of automobile.For example, if will produce the wheel nut reference diameter at assembly shop is 140mm, 115mm and these three kinds of vehicles of 100mm, will tighten function with a diaxon and satisfy above three kinds of vehicles simultaneously and use, what just be necessary to design tightening machine tightens a variable pitch device to realize its function.
Summary of the invention
The purpose of this invention is to provide that a kind of easy and simple to handle, manufacturing process is simple, long service life and the low dual-shaft electric screw down distance-variation apparatus of maintenance cost, to solve the technical problem that traditional tightening machine can not be suitable for the wheel set of multiple vehicle.
The technical solution adopted for the present invention to solve the technical problems is: a kind of dual-shaft electric screw down distance-variation apparatus is provided, tighten the distance of axle in order to change, it comprises the front end gripper shoe, be fixed on the support on the described gripper shoe, described dual-shaft electric screw down distance-variation apparatus further comprises the countercylinder that is fixed on the described support, be fixed on the locating part on described countercylinder one end, inboard near described support two ends is provided with two relative limited blocks that are fixed on the described gripper shoe, be located in the middle of described two limited blocks and be fixed on locating piece on the described gripper shoe, be fixed on the master cylinder on the described locating piece, be arranged on two slide rails between the limited block, and on described slide rail, slide and offer a slide block of tightening the opening that axle passes for described, described master cylinder is controlled the slip of described slide block, and described countercylinder is controlled described locating part and moved.
Described two slide blocks slide between described limited block and described locating piece respectively.
Described master cylinder comprises two master cylinders controlling each slide block respectively.
Described locating part be shaped as U-shaped.
With respect to prior art, tighten the axle change and realize tightening a displacement thereby the position of dual-shaft electric screw down distance-variation apparatus of the present invention by variable pitch device changes to drive, solve tightening machine and can satisfy the needs of multiple vehicle shared (having different lug nut reference diameters), realize that a kind of tightening machine can be suitable for multiple vehicle, advantage such as that dual-shaft electric screw down distance-variation apparatus of the present invention has is easy and simple to handle, manufacturing process simple, long service life, maintenance cost are low.
Description of drawings
Fig. 1 is the structural representation of dual-shaft electric screw down distance-variation apparatus of the present invention.
Fig. 2 is a dual-shaft electric screw down distance-variation apparatus of the present invention and tighten the structural representation that axle cooperates.
The specific embodiment
The present invention is further elaborated with the specific embodiment with reference to the accompanying drawings below.
As depicted in figs. 1 and 2, dual-shaft electric screw down distance-variation apparatus of the present invention is the distance of tightening axle 12 in order to change, it comprises front end gripper shoe 10, be vertically fixed on the U-shaped support 7 on this gripper shoe 10, be fixed on the countercylinder 8 on this support 7, be fixed on the U-shaped locating part 1 on these countercylinder 8 one ends, inboard near these support two ends is provided with two relative limited blocks 3 that are fixed on this gripper shoe 10, also be provided with the locating piece 6 that is fixed on this gripper shoe 10 in the middle of two limited blocks, be fixed on the master cylinder 2 on this locating piece 6, be arranged on two slide rails 4 between the limited block 3, and on this slide rail 4, slide and at the slide block 5 of being isolated by this locating piece 6.All offer on this slide block 5 for described axle 12 openings that pass 52 of tightening, the slip of these master cylinder 2 control slide blocks 5.Moving of these countercylinder 8 control U-shaped locating parts 1.
It is fixing with the slide block 5 of variable pitch device at first will to tighten axle 12, and as shown in Figure 2, this variable pitch device can be achieved as follows three kinds of wheelbase conversion.First kind of displacement: master cylinder 2 withdrawals, it is mobile on slide rail 4 that slide block 5 is followed master cylinder 2 simultaneously, and when two slide blocks 5 were fitted with locating piece 6 respectively, this moment, slide block 5 stopped, and promptly finished first kind of wheelbase conversion.Second kind of displacement: countercylinder 8 stretches out pushes ahead U type limited block 1, and master cylinder 2 is started working then, two slide blocks 5 are released to two ends respectively, when slide block 5 with after U type limited block 1 contact, slide block 5 stops to move, and has realized second kind of wheelbase conversion at this moment.The third displacement: countercylinder 8 is regained, and master cylinder 2 work are pushed two slide blocks 5 to two ends, and after the limited block 3 at slide block 5 and two ends contacted, slide block 5 stop motions had realized the third wheelbase conversion this moment.Then these three kinds of displacements are compiled program simultaneously and separately the program of tightening of the corresponding vehicle of wheelbase integrate, select by the shifting switch on the guidance panel.
Operating procedure: the first step: select the gear of Gear-shift switch according to actual vehicle needs, this moment, equipment carried out automatic adjustable-pitch; Second step: with the jacket casing of required vehicle on the hydraulic quick coupler of tightening on the axle 12; The 3rd step: press the start button on the operating grip, equipment is started working.
Dual-shaft electric screw down distance-variation apparatus of the present invention has solved tightening machine can satisfy the needs of multiple vehicle shared (having different lug nut reference diameters), tighten the axle change and realize tightening a displacement thereby the position by variable pitch device changes to drive, just realize that also a kind of tightening machine can be suitable for multiple vehicle, the variable pitch device that present embodiment is fallen into a trap is applicable to the diaxon tightening machine, can realize the conversion of three kinds of wheelbases.Advantages such as that dual-shaft electric screw down distance-variation apparatus of the present invention has is easy and simple to handle, manufacturing process simple, long service life, maintenance cost are low.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
