[0015] This specific embodiment is a tooling fixture for a round hardware workpiece, and its structural schematic diagram is as follows. Figures 1-6As shown, it includes: a bracket 7, a rotating shaft 17 rotatably mounted through the outer surface of the bracket 7, a rotating clamp 14 mounted on the outer surface of the rotating shaft 17, a pipe groove 18 provided on the outer surface of the rotating clamp 14, and a hardware pipe 9 provided inside the pipe groove 18, a motor 16 mounted on the outer surface of the bracket 7, and the output end of the motor 16 fixedly connected to the rotating shaft 17, a mounting frame 4 mounted on the outer surface of the bracket 7, and a cylinder 6 mounted on the outer surface of the mounting frame 4, a positioning clamp 19 mounted on the telescopic end of the cylinder 6, a pipe expander 8 provided outside the bracket 7, a pipe inlet mechanism provided outside the rotating clamp 14, and an anti-slip mechanism mounted on the outer surface of the bracket 7.

[0016] Specifically, through the configuration of motor 16, the controller sends a pulse signal to the stepper driver, which then controls motor 16 to rotate 60 degrees. The rotation of motor 16 drives the rotating shaft 17 and the rotating clamp 14 to rotate. The rotation of the rotating clamp 14 drives the tube groove 18 and the hardware tube 9 to rotate intermittently at 60-degree intervals. When the rotating clamp 14 stops, cylinder 6 is activated to push the positioning clamp 19 to press against its corresponding hardware tube 9, fixing the hardware tube 9 within the tube groove 18. The tube expander 8 then starts to expand the hole in the hardware tube 9. After the expansion is complete, the tube expander 8 separates from the hardware tube 9, and cylinder 6 pulls the positioning clamp 19 away from its corresponding hardware tube 9. Motor 16, controlled by the controller, rotates 60 degrees, driving the rotating shaft 17 and the rotating clamp 14 to rotate. The hardware tube 9 in the tube groove 18, located directly above the rotating clamp 14, rotates to the position corresponding to the positioning clamp 19. Cylinder 6... The positioning fixture 19 is activated to press the corresponding metal tube 9 for repeated processing. The rotating fixture 14 rotates, and the metal tube 9 in the tube groove 18 located below it automatically slides down and falls under the action of gravity, realizing the automatic unloading of the metal tube 9. By setting the rotating fixture 14 and the positioning fixture 19, the metal tube 9 is rotated and fixed, so that the stroke of the metal tube 9 is shorter when changing and fixing the metal tube 9, and the fixing speed of the metal tube 9 is increased. With the automatic feeding and unloading of the metal tube 9, the feeding or unloading speed is shortened and the steel pipe processing speed is increased. During the rotation of the rotating fixture 14, the metal tube 9 is continuously put into the empty tube groove 18 on the surface of the rotating fixture 14 under the action of the tube feeding mechanism, realizing the automatic feeding of the metal tube 9. Under the action of the anti-slip mechanism, the end of the metal tube 9 away from the tube expander 8 can be positioned to prevent the metal tube 9 from moving during rotation and to ensure the stability of the metal tube 9 during rotation.

[0017] Furthermore, the tube feeding mechanism includes a tube 1, the tube 1 is provided on the outside of the rotating clamp 14, and the bottom end of the tube 1 is in contact with the outer surface of the rotating clamp 14. A support frame 15 is installed on the bottom surface of the tube 1.

[0018] Specifically, by arranging the hardware tubes 9 in the tube cylinder 1, when the rotating clamp 14 rotates, the hardware tubes 9 in the tube cylinder 1 automatically roll into the empty tube groove 18 on the surface of the rotating clamp 14 under the action of gravity, thereby realizing the automatic feeding of the hardware tubes 9.

[0019] Furthermore, an arc-shaped frame 5 is installed on the outer surface of the tube 1, and the arc-shaped frame 5 is attached to the outside of the rotating clamp 14.

[0020] Specifically, the arc-shaped frame 5 presses against the outside of the rotating clamp 14 to prevent the internal hardware tube 9 of the tube groove 18 from jumping when the rotating clamp 14 rotates.

[0021] Furthermore, a baffle plate 10 is fixedly connected to the outer surface of the tube 1, and the end of the hardware tube 9 near the tube expander 8 is in contact with the baffle plate 10.

[0022] Specifically, when the metal tube 9 falls from the tube cylinder 1 into the tube groove 18, the baffle 10 blocks the end of the metal tube 9 away from the tube expander 8 to prevent the metal tube 9 from moving when it falls from the tube cylinder 1 into the tube groove 18.

[0023] Furthermore, two viewing windows 2 are provided on the outer surface of the tube 1.

[0024] Specifically, the viewing window 2 allows staff to easily observe the status of the metal tube 9 inside the tube 1, and also allows staff to easily tidy up the metal tube 9 inside the tube 1 through the viewing window 2.

[0025] Furthermore, the bottom end of the support frame 15 is fixedly installed to the bracket 7 with screws.

[0026] Specifically, bracket 7 and support frame 15 are fixedly installed to increase their stability.

[0027] Furthermore, a discharge hopper 3 is fixedly connected to the outer surface of the support 7, and the discharge hopper 3 is arc-shaped.

[0028] Specifically, the discharge hopper 3 can catch the falling metal tube 9 and make the metal tube 9 slide down, making it convenient for the metal tube 9 to fall.

[0029] Furthermore, the anti-slip mechanism includes a groove 11. The outer surface of the rotating clamp 14 is provided with a groove 11. An electromagnet ring 12 is provided inside the groove 11. A fixing plate 13 is installed on the outer surface of the electromagnet ring 12, and the fixing plate 13 is fixedly connected to the bracket 7.

[0030] Specifically, the electromagnet ring 12 is energized to generate a suction force to attract and position the end of the metal tube 9 away from the tube expander 8, preventing the metal tube 9 from moving around when rotating and increasing the stability of the metal tube 9 when rotating. When the metal tube 9 rotates to the side below the rotating clamp 14, the electromagnet ring 12 separates from the metal tube 9, causing the metal tube 9 to fall automatically.

[0031] This utility model discloses a tooling fixture for a circular hardware workpiece. Through the setting of a motor 16, the motor 16 uses a controller to send a pulse signal to a stepper driver, which then controls the motor 16 to rotate 60 degrees. The rotation of the motor 16 drives the rotating shaft 17 and the rotating fixture 14 to rotate. The rotation of the rotating fixture 14 causes the tube groove 18 and the hardware tube 9 to rotate intermittently at 60-degree intervals. When the rotating fixture 14 stops, the cylinder 6 is activated to push the positioning fixture 19 to press against the corresponding hardware tube 9, fixing the hardware tube 9 within the tube groove 18. The tube expander 8 is then activated to expand the hole in the hardware tube 9. After the expansion is complete, the tube expander 8 separates from the hardware tube 9, and the cylinder 6 pulls the positioning fixture 19 away from its corresponding hardware tube 9. The motor 16, controlled by the controller, rotates 60 degrees, driving the rotating shaft 17 and the rotating fixture 14 to rotate. The hardware tube 9, located in the tube groove 18 directly above the rotating fixture 14, rotates until it is aligned with the positioning fixture 19. At the corresponding position, the cylinder 6 starts to push the positioning clamp 19 to squeeze the corresponding hardware tube 9 for repeated processing. The rotating clamp 14 rotates and the hardware tube 9 in the tube groove 18 located on its lower side automatically slides down and falls under the action of gravity, realizing the automatic unloading of the hardware tube 9. Through the setting of the rotating clamp 14 and the positioning clamp 19, the hardware tube 9 is rotated and fixed, so that the stroke of the hardware tube 9 during material change and fixing processing is shorter, and the fixing speed of the hardware tube 9 is improved. With the automatic feeding and unloading of the hardware tube 9, the feeding or unloading speed is shortened, and the steel pipe processing speed is increased. During the rotation of the rotating clamp 14, under the action of the tube feeding mechanism, the hardware tube 9 is continuously put into the empty tube groove 18 on the surface of the rotating clamp 14, realizing the automatic feeding of the hardware tube 9. Under the action of the anti-slip mechanism, the end of the hardware tube 9 away from the tube expander 8 can be positioned to prevent the hardware tube 9 from moving during rotation and to ensure the stability of the hardware tube 9 during rotation.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
