When the welding surfaces are in contact with each other, the air bag 5 can be difficult to push the auxiliary weldment to press against the main weldment, deformation and slipping can occur, the situation of flash generation can be reduced, when pressure is provided by welding, the main weldment can be reduced by displacement amount due to the limit of the end pressure structure 9, when thicker workpieces are difficult to be heated by induction, the external motor and the speed reducer drive chuck 8 rotate along the axle box 7, the main weldment clamped by the clamping jaws 10 can be driven to rotate, friction welding is performed between the main weldment and the auxiliary weldment while pressure is continuously applied, and the processing length and the welding mode of the structure can be flexibly adjusted according to different weldment sizes and weldment types, so that the operation is more flexible.
As shown in fig. 7, the end pressing structure 9 includes a pressing box 901, a buffer shell 902 is bolted to the inner side of the pressing box 901, a pressing sheet 903 is slidably connected to the inner side of the buffer shell 902, a spring 904 is fixedly connected to the right side of the pressing sheet 903, a cross bar 905 is fixedly connected to the right side of the spring 904 and the pressing box 901, a contact piece 906 is fixedly connected to the left side of the cross bar 905, by arranging the pressing box 901, the main weldment is limited when the main weldment contacts with the contact piece 906, when the main weldment is pressed by force, the contact piece 906 and the cross bar 905 contacted with the main weldment move along the inner side of the buffer shell 902, and the inner side of the buffer shell 902 is pushed to circulate with fluid medium so as to play a buffering effect, at this time, the spring 904 is deformed, after welding is completed or when pressing is stopped, the spring 904 is rebound and reset, and the displacement amount provided for the main weldment can reduce the generation of flash by reducing the relative pressure of the main weldment and the auxiliary weldment.
As shown in fig. 1, a guide rail 22 is fixedly connected to the bottom of the main welding platform 1, a screw rod 23 is rotatably connected to the inner side of the guide rail 22, a transmission block 24 is screwed to the outer side of the screw rod 23, the top of the transmission block 24 is fixedly connected with the axle box 7, the outer side of the transmission block 24 is slidably connected with the guide rail 22, the guide rail 22 is matched with the screw rod 23, and the transmission block 24 rotates along the guide rail 22 to drive the axle box 7 to horizontally move when the screw rod 23 rotates.
In brief, when welding, the air bag 5 is continuously forced to push the auxiliary weldment to press against the main weldment, but deforms and slips, so that the flash can be reduced, when welding provides pressure, the contact piece 906 and the cross bar 905 which are contacted with the auxiliary weldment move along the inner side of the buffer shell 902, and the internal fluid medium is pushed to circulate from the opening of the inner side of the buffer shell 902 to play a buffering role, at the moment, the spring 904 deforms, after the welding is finished or when the pressing is stopped, the spring 904 is rebounded and reset, the displacement provided for the main weldment can reduce the flash by reducing the relative pressure of the main weldment and the auxiliary weldment, when thicker workpieces are difficult to be heated by induction, the external motor and the speed reducer drive chuck 8 rotate along the axle box 7, the main weldment clamped by the clamping jaws 10 can be driven to rotate, and friction welding is carried out between the main weldment and the auxiliary weldment while the pressure is continuously applied.
