[0035] like Figure 1 , Figure 2 As shown, a quick-change mechanism for a press machine's upper carrier includes a quick-change mounting assembly and an upper carrier assembly. The quick-change mounting assembly includes a top abutment plate 1, a set of slot blocks penetrating the top abutment plate 1, and a drive module that drives the slot blocks to rise and fall relative to the top abutment plate 1. The mechanical locking and releasing of the upper carrier assembly is achieved through the rising and falling of the slot blocks. The slot blocks are fixed to a mounting plate 2. The two sides of the lower end face of the top abutment plate 1 are provided with supports for the upper carrier assembly along the Y-axis (e.g., ...). Figure 1 A guide component (as shown) that guides the card protrusion group to engage with the card slot block group by pushing it in the direction shown. Figure 2 , Figure 3 As shown, the guide assembly includes a pair of parallel first guide members and second guide members. The first guide member is a first linear guide wheel group 3, and the second guide member is a second linear guide wheel group 4. The slot block group includes multiple slot blocks, and each slot block is provided with a T-shaped groove 5 whose length direction is parallel to the Y-axis direction (e.g., Figure 6 (as shown); Figure 3 , Figure 5 , Figure 6 As shown, the plurality of slot blocks include a plurality of first slot blocks 6 disposed in the top abutment plate 1 on the side biased towards the upper vehicle assembly, and a plurality of second slot blocks 7 disposed in the top abutment plate 1 away from the side biased towards the upper vehicle assembly. The plurality of first slot blocks 6 and the plurality of second slot blocks 7 are the same in number and are aligned one-to-one along the Y-axis direction; a stop plate 8 (e.g., ...) is provided at the end of the T-shaped groove 5 of each second slot block 7 away from the first slot block 6. Figure 6 As shown). Figure 1 , Figure 5 As shown, the drive module includes a lifting drive component and a connecting rod 10. The lifting drive component is mounted on the first mounting plate 11. In this embodiment, there are two drive modules, resulting in a more uniform and stable lifting driving force on the slot block assembly. The lifting drive component is a cylinder 9. Figure 5As shown, the middle part of the connecting rod 10 is hinged to the lower end surface of the first mounting plate 11. One end of the connecting rod 10 is hinged to the movable part of the lifting drive component, and the other end is hinged to the top surface of the adapter plate 2. The top abutment plate 1 is located below the first mounting plate 11 and is fixed to the first mounting plate 11. Figure 3 As shown, a vertical positioning element is provided on the lower end face of the top plate 1; in this embodiment, the positioning element is a positioning pin 12, which realizes the precise positioning of the upper carrier assembly on the quick-change installation assembly.

[0036] like Figure 1 As shown, the quick-change mounting assembly is mounted on the second mounting plate 13. The quick-change mounting assembly also includes a third mounting plate 14 and multiple pressure sensors 15. The third mounting plate 14 is located above the second mounting plate 13 and is fixedly mounted on the second mounting plate 13. The multiple pressure sensors 15 pass through the second mounting plate 13 and are mounted on the third mounting plate 14 and the first mounting plate 11. The multiple pressure sensors 15 detect the pressure of the upper carrier assembly on the product and alarm when the pressure is abnormal. Furthermore, the lower end of each pressure sensor 15 is fixed to the upper surface of the first mounting plate 11, and the upper end is fixed to a screw 16. The screw 16 passes through the third mounting plate 14, and the screw shank of the screw 16 is fitted with a spring 17 that is compressed between the third mounting plate 14 and the pressure sensor 15. In this embodiment, the screw 16 passes through the third mounting plate 14 but is not connected to it. The screw 16 is tightened and fixed to the third mounting plate 14 by a compressed spring 17. The spring 17 provides elastic cushioning to protect the pressure sensor 15 and prevent excessive lifting force from damaging it. Figure 1 , Figure 2 As shown, the second mounting plate 13 has openings for mounting multiple linear bearings 18, and the upper end face of the first mounting plate 11 has multiple guide rods 19 fixed thereon. The multiple guide rods 19 are slidably assembled in the multiple linear bearings 18 respectively.

[0037] like Figure 4 , Figure 7 As shown, the upper carrier assembly is detachably mounted on the quick-change mounting assembly; its structure includes a top plate 20 and a set of protruding parts that engage with the slot block assembly on the top surface of the top plate 20. The top plate 20 has positioning holes corresponding to the positioning components. The two sides of the top plate 20 are respectively provided with a first guide boss and a second guide boss 21 that slide and engage with the first guide component and the second guide component. The guide assembly enables the upper carrier assembly to be self-guided and pushed horizontally along the Y-axis direction. The operator only needs to apply force in one direction to complete the precise docking of the quick-change mounting assembly and the upper carrier assembly. The protruding parts include multiple protruding parts 22, each of which is a T-shaped block that matches the T-slot 5. Figure 2 As shown, each upper carrier assembly also includes a pressure plate 23 fixed to the lower end of the top plate 20 to press the product together, and the lower end of the pressure plate 23 is provided with a positioning post 24 that is positioned with the carrier plate.

[0038] The working principle of the quick-change mechanism for the upper carrier of the pressing machine in this utility model is as follows: When it is necessary to change the upper carrier assembly to suit different products (the structures of the pressure plate 23 are different between the upper carrier assemblies that are to be replaced, but the structures used for quick change are the same), the piston rod of the cylinder 9 retracts upward, thereby driving the adapter plate 2 to descend through the connecting rod 10, which in turn drives the multiple first slot blocks 6 and multiple second slot blocks 7 fixedly installed on the adapter plate 2 to descend, thereby driving the upper carrier assembly, which is engaged with the multiple first slot blocks 6 and multiple second slot blocks 7 by multiple locking protrusions 22, to descend and land on the first linear guide wheel group 3 and the second linear guide wheel group 4, so that the top plate 20 is disengaged from the top abutment plate 1, and the positioning pin 12 is disengaged from the positioning hole in the top plate 20. Then, the entire upper carrier assembly is pulled outward from the first linear guide wheel group 3 and the second linear guide wheel group 4, while the multiple locking protrusions 22 move outward from the multiple first slot blocks. The first upper carrier assembly is removed from the first and second slot blocks 7. Then, the other upper carrier assembly is placed on the first linear guide wheel group 3 and the second linear guide wheel group 4 and pushed inward. The multiple protrusions 22 on the top plate 20 of the other upper carrier assembly are pushed into the multiple first slot blocks 6 and multiple second slot blocks 7 until they are blocked by the stop plates 8 in the multiple second slot blocks 7. The piston rod of the cylinder 9 extends downward and drives the adapter plate 2 to rise through the connecting rod 10. This drives the other upper carrier assembly, which is fixed in the multiple first slot blocks 6 and multiple second slot blocks 7 by the protrusions 22, to rise. This causes the top plate 20 of the other upper carrier assembly to abut against the top plate 20. At the same time, the positioning pin 12 is inserted into the positioning hole in the top plate 20. This pulls the other upper carrier assembly up and fixes it on the quick-change mounting assembly, completing the quick replacement of the other upper carrier assembly and enabling a single machine to adapt to the pressing needs of multiple products.
