DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1: Refer to the attached specification Figure 1-3 The utility model is a mechanical arm for 4D printing thermal recovery, including a mounting part 1, see Figure 1 A control panel 2 is fixedly mounted on one side of the mounting member 1, a mounting plate 3 is fixedly mounted on the top of the mounting member 1, and a mechanical arm body 4 is arranged on the top of the mounting plate 3. For details, see Figure 3 The outer wall of the robot arm body 4 is rotatably connected with a connecting tube 5, and a V-shaped groove 6 is opened on the outer wall of the connecting tube 5. A plug rod 7 is inserted inside the connecting tube 5, and one end of the plug rod 7 is fixedly connected with a connecting piece 8, which is inserted in the outer wall of the connecting tube 5. A card block 9 is slidably connected inside the connecting piece 8, and the card block 9 is inserted in the V-shaped groove 6. The outer wall of the card block 9 is provided with a threaded sleeve 10, and the threaded sleeve 10 is connected to the outer wall of the connecting piece 8 by threading. By setting an annular groove inside the threaded sleeve 10, when the annular groove of the threaded sleeve 10 is aligned with the card block 9, the card block 9 can be detached from the inside of the V-shaped groove 6 and enter the annular groove opened inside the threaded sleeve 10, so that the limit of the connecting piece 8 and the connecting tube 5 disappears.

[0021] It should be noted that, when the staff needs to replace the clamping component of the robot arm according to the shape of the 4D printed sample, the staff can rotate the threaded sleeve 10 to make the threaded sleeve 10 move along the thread of the outer wall of the connecting piece 8, so that the threaded sleeve 10 gradually stops limiting the block 9, and the annular groove inside the threaded sleeve 10 is aligned with the block 9. At this time, the block 9 loses its limit, and the staff can pull the connecting piece 8 to make the connecting piece 8 drive the plug 7 to stop contacting the connecting tube 5, so that the block 9 driven by the connecting piece 8 is relatively squeezed by the V-shaped groove 6, so that the block 9 slides along the inside of the connecting piece 8 and is squeezed out of the inside of the V-shaped groove 6, so as to achieve the effect of quickly disassembling the clamping component, which is convenient for the staff to replace the unfixed part according to the shape of the 4D printed sample. The same clamping parts, and it is convenient for the staff to disassemble the clamping parts for inspection and maintenance. It should be noted that when the staff needs to install the clamping parts, they can align the insertion rod 7 and the connecting part 8 with the connecting tube 5, and then insert the V-shaped groove 6 into the interior of the connecting tube 5 and sleeve the connecting part 8 on the outer wall of the connecting tube 5. At this time, the staff can rotate the threaded sleeve 10 to make the threaded sleeve 10 slide along the outer wall of the connecting part 8, and then make the threaded sleeve 10 squeeze the connecting part 8 to slide along the inside of the connecting part 8 and insert it into the inside of the V-shaped groove 6, so that the block 9 connects and fixes the connecting tube 5 and the connecting part 8, and the threaded sleeve 10 limits the block 9, so as to achieve the effect of quickly fixing the clamping part on the robotic arm, which is convenient for the staff to replace and install the clamping parts.

[0022] Embodiment 2: A motor 11 is fixedly installed inside the connecting member 8, and a driving gear 12 is fixedly connected to the output shaft of the motor 11. A reduction gear set 13 is meshed with the outer wall of the driving gear 12. The reduction gear set 13 is arranged inside the connecting member 8. A driven gear 14 is meshed with the outer wall of the reduction gear set 13. A bidirectional threaded rod 15 is fixedly installed inside the driven gear 14. A connecting plate 16 is rotatably connected to the outer wall of the bidirectional threaded rod 15. The connecting plate 16 is fixedly installed on the outer wall of the connecting member 8. A slide plate 17 is slidably connected to the inside of the connecting plate 16. The slide plate 17 is threadedly connected to the outer wall of the bidirectional threaded rod 15. A pressure sensor 18 is fixedly installed inside the slide plate 17. A clamping plate 19 is fixedly connected to one side of the pressure sensor 18. The clamping plate 19 is arranged inside the slide plate 17.

[0023] It should be noted that when the staff needs to control the robotic arm to clamp and transport the 4D printed samples, the staff can input the program or call out the program through the control panel 2, so that the program controls the robotic arm to work, and then after the driven clamping plate 19 is moved to the 4D printed sample, the control panel 2 will control the motor 11 to work, and finally the bidirectional threaded rod 15 rotates to drive the slide plate 17 to slide along the inside of the connecting plate 16, so that the slide plate 17 pushes the clamping plate 19 to clamp and fix the sample. When the pressure sensor 18 senses sufficient pressure through the clamping plate 19, the pressure sensor 18 will transmit the pressure signal to the inside of the control panel 2, so that the control panel 2 controls the motor 11 to stop working and control the robotic arm to execute subsequent program steps. At this time, the clamping plate 19 stops pressurizing the sample, and the robotic arm transports the sample to the destination to prevent the sample from being damaged due to excessive clamping force or falling due to insufficient clamping force.
