For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, in the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0019] Any process or method description in the flowchart or otherwise described herein may be understood to represent a module, fragment or portion of code that includes one or more executable instructions for implementing the steps of a specific logical function or process, and the scope of the preferred embodiments of the present invention includes alternative implementations in which functions may not be performed in the order shown or discussed, including performing functions in a substantially simultaneous manner or in the reverse order depending on the functions involved, which should be understood by technicians in the technical field to which the embodiments of the present invention belong.

[0020] like Figures 1 to 5 As shown, the utility model provides a rolling mold switching mechanism for an automobile welding production line, comprising a transverse sliding track 1, a rolling station 2 arranged in the middle of the transverse sliding track 1, and loading and unloading stations 3 installed at both ends of the transverse sliding track 1; a conveyor 4 is installed on the transverse sliding track 1, and the transverse sliding track 1 includes two transversely parallel transverse slide rails 5, a transverse slider 6 slidably installed on the transverse slide rail 5 and a transverse rack 7 installed parallel to the transverse slide rail 5, the conveyor 4 is fixedly installed on the transverse slider 6, and a transverse driving motor 8 is installed on the conveyor 4, and a transverse driving gear 9 is installed at the output end of the transverse driving motor 8, and the transverse driving gear 9 is meshed with the transverse rack 7; the transverse driving motor 8 can drive the conveyor 4 to move between the rolling station 2 and the loading and unloading station 3 along the transverse sliding track 1.

[0021] The loading and unloading station 3 includes a longitudinal switching device 10 installed perpendicular to the transverse sliding track 1, the longitudinal switching device 10 includes a longitudinal switching track 11 composed of a plurality of rollers arranged in the longitudinal direction, a longitudinal pushing rack 12 arranged in parallel with the longitudinal switching track 11, a longitudinal slide rail 13 arranged in parallel with the longitudinal switching track 11, a longitudinal slider 14 slidably mounted on the longitudinal slide rail 13 and a pushing seat 15 fixedly mounted on the longitudinal slider 14, a longitudinal pushing motor 16 is provided on the pushing seat 15, a longitudinal pushing gear 17 is provided at the output end of the longitudinal pushing motor 16, and the longitudinal pushing gear 17 is meshed with the longitudinal pushing rack 12; a mounting base 18 is placed on the longitudinal switching device 10, a workpiece to be rolled is placed on the mounting base 18, the mounting base 18 moves longitudinally on the longitudinal switching track 11, the conveying vehicle 4 moves to the loading and unloading station 3, and the pushing seat 15 moves longitudinally to push the mounting base 18 from the loading and unloading station 3 to the conveying vehicle 4.

[0022] The present rolling die switching mechanism is suitable for the rolling processing of different parts and different car models such as tailgates and sliding doors, and can realize the rolling switching of different workpieces on the same rolling production line. During processing, the workpiece to be processed is transported to the loading and unloading station 3 and placed on the mounting base 18. When the processing starts, the longitudinal pushing motor 16 can push the mounting base 18 loaded with the workpiece from the loading and unloading station 3 to the conveyor 4 through the pushing seat 15, and then the transverse driving motor 8 on the conveyor 4 starts to work to move the conveyor 4 to the rolling station 2. After the rolling station 2 completes the rolling work of the workpiece on the mounting base 18, the conveyor 4 can move the completed workpiece to the loading and unloading station 3 again, and the next workpiece to be rolled continues to be transported to the rolling station 2 by other conveyor 4 to repeat the cycle.

[0023] At the loading and unloading station 3, several longitudinal switching rails 11 can be arranged horizontally, and different mounting bases 18 can be placed on the top to carry workpieces of different models or parts to be rolled. When the model needs to be switched, the mounting base 18 on the corresponding longitudinal switching rail 11 can be pushed longitudinally onto the conveyor vehicle 4. This automatic switching method expands the processing capacity of the rolling production line and can achieve flexible rolling processing and production.

[0024] The hemming station 2 includes a transport gripper 19 and a hemming head 20. The transport gripper 19 transfers the workpiece on the mounting base 18 to the hemming station 2, and the hemming head 20 performs hemming operations on the workpiece on the hemming station 2. The mounting base 18 is where the workpiece to be hemmed is placed. The transport gripper 19 grabs the workpiece and places it on the hemming station 2. The hemming station 2 switches the hemming head 20 according to the specific model of the corresponding workpiece and performs hemming. After completion, the transport gripper 19 grabs the processed workpiece and transports it to the mounting base 18, and then transfers it to the designated position of the loading and unloading station 3. The next new workpiece repeats the above hemming operation, so that the switching of hemming operations for multiple models and multiple types can be realized.

[0025] The push seat 15 is provided with a push plate 21, and the mounting base 18 is provided with a push bearing 22 near the push seat 15. The push plate 21 pushes the push bearing 22 to move along the longitudinal switching track 11. Because the longitudinal switching track 11 is composed of a plurality of rollers, the push plate 21 pushes and contacts the push bearing 22, so that the push seat 15 can avoid applying an adverse external force to the mounting base 18 during longitudinal pushing, ensuring that the mounting base 18 can be correctly guided to move in the longitudinal direction on the longitudinal switching track 11, and avoiding the mounting base 18 from running off.
