[0025] The embodiments of the present utility model first provide a double-station workbench for a hot riveting device. Refer to Figures 1 to 3 , the double-station workbench 2 mainly includes a first station component 21 and a second station component 22 connected to the support base 1. Among them, the support base 1 has a frame structure, and an accommodation space is provided inside it, which can place some structural components or drive components of the device, etc.
[0026] Among them, the first station component 21 includes a first linear drive module 211 and a first workpiece carrier plate 212. The first linear drive module 211 is connected to the support base 1, the first workpiece carrier plate 212 is connected to the first linear drive module 211, and the first linear drive module 211 can drive the first workpiece carrier plate 212 to reciprocate linearly in the horizontal plane.
[0027] Among them, the second station component 22 includes a second linear drive module 221, a transmission carrier plate 222, a lifting drive module 223, and a second workpiece carrier plate 224. The second linear drive module 221 is connected to the support base 1 and is located below the first linear drive module 211. The transmission carrier plate 222 is connected to the second linear drive module 221. The second workpiece carrier plate 224 is connected to the transmission carrier plate 222 in a liftable manner through the lifting drive module 223. The second linear drive module 221 can drive the transmission carrier plate 222 to drive the second workpiece carrier plate 224 to reciprocate linearly in the horizontal plane. The lifting drive module 223 can drive the second workpiece carrier plate 224 to reciprocate vertically. The second workpiece carrier plate 224 can be driven by the lifting drive module 223 to rise to the working plane where the first workpiece carrier plate 212 is located.
[0028] Wherein, a plurality of positioning holes 212a and 224a arranged in an array are respectively provided on the upper surfaces of the first workpiece carrier 212 and the second workpiece carrier 224. By configuring positioning pins (not shown in the drawings) corresponding to the positioning holes 212a and 224a, positioning can be performed for a variety of workpieces to be processed with different specifications. Specifically, according to the size of the workpiece to be processed, several positioning holes 212a and 224a at appropriate positions are selected, and the positioning pins are inserted to fixedly connect the workpiece to be processed to the first workpiece carrier 212 or the second workpiece carrier 224.
[0029] Specifically, in this embodiment, as Figure 2 shown, the first linear drive module 211 includes two first linear motors 211a arranged at intervals in a first direction (such as the X direction in Figure 2 ), and both ends of the first workpiece carrier 212 are respectively connected to the two first linear motors 211a.

Wherein, the length of the second workpiece carrier 224 in the first direction is less than the distance between the two first linear motors 211a. Thus, the second workpiece carrier 224 can be driven by the lifting drive module 223 to rise to the working plane where the first workpiece carrier 212 is located.

Each column of guide shafts 225 includes a plurality of guide shafts 225 arranged at intervals in sequence in the second direction. A lifting cylinder 226 is arranged between any two adjacent guide shafts 225 in each column of guide shafts 225. Based on this structural arrangement, the lifting drive of the second workpiece carrier plate 224 can be made more stable. Further, the first ends of all the guide shafts 225 in each column of guide shafts 225 are fixedly connected to a fixing plate member 227, the output shaft of the lifting cylinder 226 located in this column of guide shafts 225 is connected to the fixing plate member 227, and the lower surface of the second workpiece carrier plate 224 is connected to the fixing plate member 227.

[0035] (2), as Figure 2 shown, after the loading and unloading operation of the second workpiece carrier plate 224 is completed, the lifting drive module 223 drives the second workpiece carrier plate 224 to descend, and the second linear drive module 221 moves the second workpiece carrier plate 224 backward along the Y direction to the lower part of the first workpiece carrier plate 212.
[0036] (3), as Figure 5After the hot riveting operation of the first workpiece carrier 212 is completed, the first linear drive module 211 moves the first workpiece carrier 212 forward in the Y direction to the loading and unloading operation position, and the operator performs the loading and unloading operation on the first workpiece carrier 212. At this time, the lifting drive module 223 drives the second workpiece carrier 224 to rise to the hot riveting operation position for hot riveting operation.
[0037] (4) After the hot riveting operation of the second workpiece carrier 224 is completed, the lifting drive module 223 drives the second workpiece carrier 224 to descend. At this time, the first workpiece carrier 212 has completed the loading and unloading operation, and the above actions (1) to (4) are cycled. The first workpiece carrier 212 and the second workpiece carrier 224 are alternately switched between the hot riveting operation position and the loading and unloading operation position.

When one workpiece carrier is driven to the hot riveting operation position for hot riveting operation, the other workpiece carrier is driven to the loading and unloading operation position for loading and unloading operations, thereby reducing the waiting time of the equipment and improving the production efficiency.
[0040] The above are only specific embodiments of the present application.
