Description
Technical field
The utility model relates to a kind of flash butt welder, specifically is meant a kind of flash butt welder that is used for welding of automotive wheel hub circle.
Background technology
Along with the development of industrial technology, solder technology is more and more perfect, and it is used also more and more widely, and in the prior art, the wheel hub circle of automobile also generally adopts flash butt welder to weld.The flash butt welder that is used for welding of automotive wheel hub circle in the prior art mainly is the structure that adopts shown in accompanying drawing 1; It comprises flash butt welder main body 1 '; Flash butt welder main body 1 ' is provided with pusher drive unit 3 '; Pusher drive unit 3 ' links to each other with removable guide holder 2 ' through expeller 4 ', and pusher drive unit 3 ' promotes expeller 4 ' motion, and expeller 4 ' drives removable guide holder 2 ' motion again and accomplishes the butt welding action.Be divided into two stages during flash butt welding: the one, the upset stage; The 2nd, in the flash of light stage, two kinds of required upset forces of stage are different, and upset speed is different.Pusher drive unit 3 ' of the prior art is to adopt cylinder or oil cylinder mostly; There is following problem in these two kinds of drive units when reality is used: cylinder or oil cylinder are under the certain situation of cylinder diameter, and its output pressure F is a definite value, and speed V is a definite value; Be difficult to debug and meet the requirement of flash welding different phase; Influence the welding quality of product, influence weld labour intensity, it is attractive in appearance to influence weld.
The utility model content
The technical problem underlying that the utility model will solve is that a kind of higher flash butt welder of controllability of fltting speed of pusher drive unit is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model provides is: a kind of flash butt welder; It comprises flash butt welder main body and pusher drive unit, and the front end of pusher drive unit is connected with expeller, and said pusher drive unit is a servo drive; Described servo drive comprises servomotor, ball-screw and shaft coupling; Servomotor is fixed on the flash butt welder main body, and the rotating shaft of servomotor is rotationally connected through the screw rod of shaft coupling and ball-screw, and the nut of ball-screw is fixedly connected with expeller.
After adopting above structure; The utlity model has following advantage: described servo drive comprises servomotor, ball-screw and shaft coupling; Servomotor is fixed on the flash butt welder main body; The rotating shaft of servomotor is rotationally connected through the screw rod of shaft coupling and ball-screw, and the nut of ball-screw is fixedly connected with expeller.Servomotor is through the rotating of the screw rod of forward and reverse control ball-screw, and this moment, the nut of ball-screw will produce rectilinear motion when screw mandrel rotates because servomotor is fixed, thereby realizes the rectilinear motion on the expeller left and right directions.Than drive unit of the prior art, servomotor have high-speed response property, upset force and a upset speed in the time of can accurately controlling flash butt welding; Welding performance is stable, reliable, to different welding products, different upset speeds can be set; Realize a tractor serves several purposes, improved energy utilization rate.In sum, the utility model provides a kind of higher flash butt welder of controllability of fltting speed of pusher drive unit.
As preferably, described expeller power transmission face (end face of an end that promptly contacts with workpiece to be processed) is the inclined-plane, and the angle of described inclined-plane and horizontal plane (being the angle shown in the θ in the accompanying drawing 2) is less than 90 degree.Ramp structure is than vertical expeller structure of the prior art, and ramp structure can reduce the shearing force to attachment screw, has increased the reliability that connects, the service life of having improved machine.
Description of drawings
Fig. 1 is the structural representation of flash butt welder in the prior art.
