[0031] The first power assembly is installed on the top plate 3 to drive the top placement plate 4 to rise and fall. The first power assembly includes a reducer 11, a first servo motor 12, a transmission shaft 8, multiple winding drums 9 and multiple winding ropes 162. Two mounting seats 10 are arranged side by side at the upper end of the top plate 3. The transmission shaft 8 is rotatably installed between the two mounting seats 10. The reducer 11 and the first servo motor 12 are both installed on the mounting seat 10 on one side. The output shaft of the first servo motor 12 is connected to the input shaft of the reducer 11, and the output shaft of the reducer 11 is connected to the transmission shaft 8. Multiple winding drums 9 are all installed on the transmission shaft 8. Multiple winding ropes 162 are respectively fixedly wound around the multiple winding drums 9. The multiple winding ropes 162 are all movable through the top plate 3 and are all connected to the top placement plate 4. The cooperation of the reducer 11 and the first servo motor 12 can increase the output torque of the first power assembly.

[0032] The two groups of limiting mechanisms are respectively movable and penetrate the mounting side plates 2 on both sides, and each group of limiting mechanisms includes a mounting column 6 and multiple groups of elastic limiting components. The multiple groups of elastic limiting components are installed side by side on the mounting column 6. The elastic limiting components include a limiting block 14, a second slide bar 221, a second spring 222 and a second limiting head 223. A plurality of mounting grooves 601 are provided on the mounting column 6. The ends of the plurality of limiting blocks 14 are respectively slidably installed in the plurality of mounting grooves 601.

The end of the second slide bar 221 movably penetrates the mounting column 6 and is connected to the second limiting head 223. The second spring 222 is sleeved and installed on the second slide bar 22 1; a second power assembly for driving two sets of limit mechanisms to move closer to or away from each other is installed on the base frame 1, and the second power assembly includes a second servo motor 17 and a bidirectional screw rod 18.

Before driving the multiple placement plates 4 to move downward, the two mounting columns 6 are first driven away.

[0033] In this embodiment, when fixing multiple pistons, the top placement plate 4 is first driven downward to a limited position by the first power assembly, so that the multiple placement plates 4 are stacked together, thereby reducing the height of the top multiple placement plates 4, so that the pistons can be easily fixed to the top placement plate 4. When installing multiple pistons, the topmost placement plate 4 is first filled with pistons, and then the top placement plate 4 is driven to move up, and then the pistons are placed on the second top placement plate 4. The above steps are followed to achieve the fixing of multiple pistons. During the upward movement of the placement plate 4, it contacts the inclined surface of the limit block 14, forcing the limit block 14 to move toward the inner side of the installation groove 601. When the placement plate 4 moves to the upper position of the limit block 14, the limit block 14 is driven to reset under the elastic force of the second spring 222. At this time, the limit block 14 is located at the bottom end of the placement plate 4, thereby achieving the effect of supporting the placement plate 4 to reduce the load of the first power assembly.
