Description

Technical Field

[0001] The utility model relates to the technical field of riveting machines, in particular to a blanking mechanism for a riveting machine. Background Art

[0002] In the electrical appliance related industries, many devices need to use metal casings. These casings are mostly composed of multiple components to form a casing that is convenient for installing electrical components. Therefore, when assembling related casings, a riveting machine is required for press riveting to assemble the casings.

[0003] In the prior art, for the casings that need to be assembled and press riveted, the related casings are calibrated manually and placed into the fixture of the riveting machine. The placed casings are clamped by the clamps arranged in the fixture, and then the casings are sent under the stamping riveting head through the movement of the fixture. The casings are press riveted and assembled through the longitudinal movement of the fixture in cooperation with the lateral movement of the stamping riveting head. After the assembly is completed, the assembled casings are taken out of the fixture manually, and then centrally transported to the next process. Manual blanking not only increases the labor intensity of the staff, but also reduces the work efficiency due to centralized transportation. Therefore, we propose a blanking mechanism for a riveting machine, which directly takes out the casings after press riveting and assembly from the riveting machine and sends them into the conveyor belt for direct blanking and transportation, reducing the labor intensity and improving the work efficiency. Content of the Utility Model

[0004] The utility model provides a blanking mechanism for a riveting machine to solve the problems raised in the background art.

[0005] To solve the above problems, the present utility model provides a blanking mechanism for a riveting machine, including a double-station riveting machine and a blanking mechanism. The double-station riveting machine is provided with a blanking window. One end of the blanking mechanism passes through the blanking window and is located in the double-station riveting machine. The blanking mechanism is composed of a conveyor belt, a guiding box, a guiding frame, and a suction cup. The conveyor belt is arranged in the middle outside the blanking window of the double-station riveting machine. The guiding box is installed above the conveyor belt through two support columns. A guiding groove is opened on one side of the guiding box facing the blanking window. A first threaded lead screw is rotatably arranged in the guiding groove, and one end of the first threaded lead screw rotatably passes through the outside of one side of the guiding box and is connected with a first servo motor. One end of the guiding frame is slidably arranged in the guiding groove and is in threaded connection with the first threaded lead screw. The end of the guiding frame away from the guiding box passes through the blanking window and is movably arranged in the double-station riveting machine. A driving groove is opened in the guiding frame, and two sliding grooves are symmetrically opened on both sides of the driving groove. A second threaded lead screw is rotatably arranged in the driving groove, and the end of the second threaded lead screw close to the guiding box is connected with a second servo motor. A driving frame is slidably connected in the guiding frame through the cooperation of the driving groove and the two sliding grooves, and the driving frame is in threaded connection with the second threaded lead screw. An electric push rod is installed at the bottom of the driving frame. The top of the suction cup is fixedly connected with the telescopic end of the electric push rod.

[0006] Preferably: One first guiding rod is respectively arranged on both sides of the first threaded lead screw in the guiding groove of the guiding box, and the guiding rod is slidably connected with the end of the guiding frame located in the guiding groove.

[0007] Preferably: Two second guiding rods are arranged in the double-station riveting machine, and the end of the guiding frame in the double-station riveting machine is slidably connected with the two second guiding rods.

[0008] Preferably: An air pump is installed at the top of the driving frame, and the air pump is connected with the suction cup through an air pipe.

[0009] The beneficial effects of adopting the above technical solutions are as follows:

[0010] The first servo motor drives the first threaded lead screw to rotate in the guiding groove, thereby driving the guiding frame to move horizontally in the guiding groove. Synchronously, the second servo motor drives the second threaded lead screw to rotate in the driving groove, thereby driving the driving frame to move longitudinally in the guiding frame. Through the horizontal movement of the guiding frame and the longitudinal movement of the driving frame, the position of the suction cup can be adjusted. As the suction cup moves horizontally and longitudinally, the riveted shells in the double-station riveting machine are sequentially adsorbed and taken out, and then sent into the conveyor belt for transfer to complete automatic blanking, which not only reduces the labor intensity of the staff but also matches the working position rhythm of the double station and improves the working efficiency.

[0018] Such as Figures 1-3, in this embodiment, a blanking mechanism for a riveting machine includes a double-station riveting machine 1 and a blanking mechanism 2. The double-station riveting machine 1 is provided with a blanking window 11. One end of the blanking mechanism 2 passes through the blanking window 11 and is located in the double-station riveting machine 1. The blanking mechanism 2 is composed of a conveyor belt 21, a guiding box 22, a guiding frame 23, and a suction cup 24. The conveyor belt 21 is arranged in the middle outside the blanking window 11 of the double-station riveting machine 1. The guiding box 22 is installed above the conveyor belt 21 through two support columns 25. A guiding groove 221 is opened on one side of the guiding box 22 facing the blanking window 11. A first threaded lead screw 31 is rotatably arranged in the guiding groove 221, and one end of the first threaded lead screw 31 rotatably passes through the outside of one side of the guiding box 22 and is connected to a first servo motor 3. One end of the guiding frame 23 is slidably arranged in the guiding groove 22 and is threadedly connected to the first threaded lead screw 31. The end of the guiding frame 23 away from the guiding box 22 passes through the blanking window 11 and is movably arranged in the double-station riveting machine 1. A driving groove 231 is opened in the guiding frame 23, and two sliding grooves 232 are symmetrically opened on both sides of the driving groove 231. A second threaded lead screw 41 is rotatably arranged in the driving groove 231, and the end of the second threaded lead screw 41 near the guiding box 22 is connected to a second servo motor 4. A driving frame 233 is slidably connected to the guiding frame 23 through the cooperation of the driving groove 231 and the two sliding grooves 232, and the driving frame 233 is threadedly connected to the second threaded lead screw 41. An electric push rod 241 is installed at the bottom of the driving frame 233. The top of the suction cup 24 is fixedly connected to the telescopic end of the electric push rod 241.

[0019] Through the above technical solution, after the riveting of one shell in the double-station riveting machine 1 is completed, the shell will be moved to a position close to the blanking window 11 through the jig. At this time, the first servo motor 3 drives the first lead screw 31 to rotate in the guide groove 221 of the guide box 22, and then drives the guide frame 23 to move horizontally in the guide groove 221, moving the guide frame 23 above the station where the shell riveting is completed. Synchronously, when the guide frame 23 moves, the second servo motor 4 drives the second lead screw 41 to rotate, and then drives the driving frame 233 to move longitudinally in the guide frame 23. Through the arrangement of the driving groove 231 and the two sliding grooves 232 in the guide frame 23, the stability of the driving frame 233 moving in the guide frame 23 can be ensured. At this time, the suction cup 24 is located above the riveted shell, and then the electric push rod 241 pushes the suction cup 24 to move downward to adsorb the shell, and then the electric push rod 241 drives the suction cup 24 to move upward to take out the riveted shell from the jig. Through the synchronous operation of the first servo motor 3 and the second servo motor 4, the suction cup 24 is moved above the conveyor belt, and then the electric push rod 241 pushes the suction cup 24 to move downward so that the shell is located in the conveyor belt. The riveted shell is transported through the conveyor belt, eliminating the need for manual blanking and reducing the workload of the staff. Since the conveyor belt 21 is located in the middle position on the outside of the double-station riveting machine 1, and the working mode of the double-station riveting machine 1 is alternate riveting work, the moving mode of the suction cup 24 in the blanking mechanism 2 can match the rhythm of the alternate riveting work of the double-station riveting machine 1, ensuring the blanking efficiency and stability.
