[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a workpiece assembly pin screwing device, including a screwing mechanism 1 and a workpiece fixing mechanism 2. The screwing mechanism 1 is used in conjunction with the workpiece fixing mechanism 2. The workpiece fixing mechanism 2 limits and fixes the workpiece, and the screwing mechanism 1 screws the assembly pin into the workpiece.

[0020] like Figure 1 and Figure 2 As shown, the workpiece fixing mechanism 2 includes a fixed slide rail 21, which is fixedly mounted on the surface of the worktable 3. A movable table 22 is slidably connected to the top of the fixed slide rail 21. The movable table 22 is connected to the transmission equipment in the production line. The transmission equipment can drive the movable table 22 to move along the fixed slide rail 21. A snap-fit ​​bracket 23 for snapping and fixing the workpiece is fixedly mounted on the surface of the movable table 22. The workpieces to be screwed into the assembly pins are snapped into the slots at different positions of the snap-fit ​​bracket 23.

[0021] An auxiliary fixing component 4 is fixedly mounted on the surface of the workbench 3. The auxiliary fixing component 4 is used to cooperate with the snap-fit ​​bracket 23 during the screwing of the assembly pin to limit and fix the workpiece in the snap-fit ​​bracket 23, so as to avoid the workpiece and the snap-fit ​​bracket 23 from shifting position during the screwing of the assembly pin, which would result in inaccurate screwing position of the assembly pin.

[0022] The auxiliary fixing component 4 includes a support frame 41. A first actuating cylinder 42 is fixedly mounted on the side wall of the support frame 41. The output end of the first actuating cylinder 42 is fixedly connected to an auxiliary fixing plate 44 through a connecting frame 43. The first actuating cylinder 42 is connected to an external air pump, which is controlled by a controller installed in the production line. The external air pump can control the first actuating cylinder 42 to drive the connecting frame 43 and the auxiliary fixing plate 44 to move up and down along the Z-axis. The auxiliary fixing plate 44 is positioned corresponding to the snap-fit ​​frame 23. When the auxiliary fixing plate 44 moves downward, it can assist in positioning the workpiece snapped and fixed in the snap-fit ​​frame 23. The surface of the auxiliary fixing plate 44 is provided with a screw-in hole 45 for mounting pins. The screw-in hole 45 is through-hole and is used for placing mounting pins during the screwing process.

[0023] like Figure 1 and Figure 3 As shown, the screwing mechanism 1 includes an assembly frame 11, which is used to connect and fix with the support structure in the production line. A second actuating cylinder 12 is fixedly mounted on the side wall of the assembly frame 11. A first actuating arm 13 is fixedly connected to the output end of the second actuating cylinder 12. The second actuating cylinder 12 drives the first actuating arm 13 to move along the Y-axis. A third actuating cylinder 14 is fixedly mounted on the side wall of the first actuating arm 13. A second actuating arm 15 is fixedly mounted on the output end of the third actuating cylinder 14. The third actuating cylinder 14 is used to drive the second actuating arm 15 to move up and down along the Z-axis. A fourth actuating cylinder 16 is fixedly mounted on the side wall of the second actuating arm 15. An assembly plate 17 is fixedly mounted on the output end of the fourth actuating cylinder 16. The fourth actuating cylinder 16 can drive the assembly plate 17 to move along the Z-axis independently.

[0024] A rotary motor 18 is fixedly mounted on the side wall of the assembly plate 17. The output end of the rotary motor 18 is fixedly connected to the assembly pin screwing shaft 19 via a coupling. The second actuating cylinder 12, the third actuating cylinder 14, and the fourth actuating cylinder 16 are respectively connected to the corresponding air pumps in the production line. The air pumps in the production line control the movement of their output ends. The second actuating cylinder 12 drives the first actuating arm 13 to move in the Y-axis direction, which can control the position and stroke of the overall screwing mechanism 1, so as to move the assembly pin screwing shaft 19 to the corresponding workpiece assembly pin assembly hole. The third actuating cylinder 14 drives the second actuating arm 15 to move in the Z-axis direction, which can control the assembly pin to be inserted into the assembly pin screwing hole 45. The rotary motor 18 is electrically connected to an external power supply and an external controller. The external controller controls the output end of the rotary motor 18 to drive the assembly pin screwing shaft 19 to rotate. During the rotation of the assembly pin screwing shaft 19, the fourth actuating cylinder 16 drives the assembly plate 17 to move downward, so as to smoothly screw the assembly pin into the corresponding hole.

[0025] A rivet clamping assembly 5 is fixedly mounted on the side wall of the second actuator arm 15. The rivet clamping assembly 5 is used to clamp and position the rivet during the screwing process with the workpiece and to remove the rivet before it is screwed into the workpiece.

[0026] The assembly nail clamping assembly 5 includes a fifth actuating cylinder 51, which is fixedly mounted on the side wall of the second actuating arm 15. The output end of the fifth actuating cylinder 51 is fixedly connected to an actuating frame 52. The fifth actuating cylinder 51 drives the actuating frame 52 to move along the Y-axis. The side wall of the actuating frame 52 is fixedly mounted with a pneumatic gripper 53. The pneumatic gripper 53 and the fifth actuating cylinder 51 are also connected to an air pump that controls them in the production line. The corresponding air pump in the production line can control the actuation of the output ends of the fifth actuating cylinder 51 and the pneumatic gripper 53 respectively. The two clamping rods fixedly connected to the output end of the pneumatic gripper 53 can clamp the assembly nails that need to be screwed into the workpiece. A feeding pipe is fixedly mounted at the bottom of the second actuating arm 15. The feeding pipe is connected to the feeding equipment in the production line. The feeding equipment blows the assembly nails into the feeding pipe. Then, the actuating frame 52 driven by the fifth actuating cylinder 51 can cooperate with the pneumatic gripper 53 to perform the nail removal operation.

[0027] like Figure 3 and Figure 5 As shown, a limiting frame 54 is fixedly mounted on the top of the pneumatic gripper 53. The limiting frame 54 is provided with a limiting hole. The limiting frame 54 is used to blow in the assembly nail during the nail removal process. The two clamping rods of the pneumatic gripper 53 are inserted into the limiting hole of the limiting frame 54 to clamp and fix the assembly nail. At the same time, the limiting frame 54 limits and guides the screwing position of the assembly nail into the screwing shaft 19, improves the perpendicularity of the assembly nail into the workpiece, and thus improves the assembly quality of the connection between the assembly nail and the workpiece.

[0028] like Figure 5 As shown, the bottom of the screw-in shaft 19 is provided with a cross groove, which allows the screw to be screwed in. The bottom of the screw-in shaft 19 is fixedly connected to a guide block 6. The bottom of the guide block 6 has an upward-facing V-shaped groove 61. When the screw-in shaft 19 drives the guide block 6 downward, it can guide the top of the screw, so that the screw can be smoothly connected to the cross groove at the bottom of the screw-in shaft 19.

[0029] Working principle: such as Figure 1 and Figure 6As shown, this utility model is installed in an automated production line and is mainly used for screwing in assembly pins for non-standard workpieces. The production line is equipped with corresponding sensors that can detect the position of the workpiece, thereby enabling the control unit within the production line to control the actions of each action unit. To screw the assembly pin into the workpiece's assembly position, firstly, the moving table 22 holding the workpiece moves to the designated assembly position. The first action cylinder 42 drives the auxiliary fixing plate 44 downwards, assisting in fixing the workpiece's position within the clamping frame 23. The second action cylinder 12 drives the first action arm 13 to move backwards, moving the second action arm 15 to the designated pin-removing position. The assembly pin is fed into the limiting frame 54 through the feeding equipment within the production line. The output end of the pneumatic gripper 53 actuates, clamping the assembly pin within the limiting frame 54 via the clamping rod. Then, the fifth action... Cylinder 51 drives the action frame 52 to move, aligning the position of the limit frame 54 with the position of the assembly pin screwing shaft 19. It controls the first action arm 13 to move, aligning the position of the limit frame 54 with the position of the assembly pin screwing hole 45. The limit frame 54 presses against the surface of the auxiliary fixing plate 44. The fourth action cylinder 16 controls the downward movement of the assembly plate 17. At the same time, during the downward movement, the rotary motor 18 drives the assembly pin screwing shaft 19 to rotate. At this time, the pneumatic gripper 53 moves to both sides and no longer clamps and fixes the assembly pin. After being guided by the guide block 6, the assembly pin completes the connection with the assembly pin screwing shaft 19. Then, the assembly pin is smoothly screwed into the workpiece by the assembly pin screwing shaft 19, completing the connection and fixation between the assembly pin and the workpiece. After the sensor in the production line detects that the assembly pin has been screwed into the designated position, each action unit resets, and the moving table 22 transfers the workpiece to the next process.
