Description

Technical Field

[0001] The utility model relates to the technical field of deburring devices, in particular to a synchronous pulley deburring device. Background Art

[0002] Synchronous pulleys are generally made of steel, aluminum alloy, cast iron, brass and other materials. Their inner holes can be round, D-shaped, tapered, etc. The surface treatments include natural oxidation, blackening, galvanizing, color zinc plating, high-frequency quenching, etc. At the same time, the pulley transmission consists of a closed ring belt with equally spaced teeth on the inner surface and a corresponding pulley.

[0003] In the past, a bench vise and a chuck were generally used to fix the synchronous pulleys when deburring. Since the burrs were located on the upper and lower surfaces of the pulley, and the bench vise clamped the pulley by clamping the upper and lower surfaces, the bench vise would block some of the burrs, and each deburring required secondary clamping, which was very troublesome. The chuck clamped the pulley by clamping the side surface. Since the side surfaces of the pulley were all teeth, the clamping force of the chuck could not be too large, otherwise the teeth would be crushed. However, this would increase the risk of the pulley loosening during deburring, affecting the deburring efficiency. Utility Model Content

[0028] As a further implementation scheme of the above technical solution: the other ends of the fixed tube 11 and the connecting tube 804 are connected to the external air pump tube, and the fixed tube 11 and the connecting tube 804 are arranged in an L shape, so that the external air pump assembly can be connected to the fixed tube 11 through the L-shaped connecting tube 804.

[0032] Working principle:

[0033] When using the present invention, the power supply of the device is connected to the external power supply, and then the components to be deburred can be placed from top to bottom in the clamping device 8 manually or with the help of a robotic arm. At this time, the components are clamped in the position where the cross bar 801 and the side bar 802 are installed with each other to form a square space, and the air pump on the outside is started. The air pump injects gas into the connecting pipe 804 and the fixed pipe 11. After the fixed pipe 11 injects gas into the telescopic rod 10, the telescopic rod 10 moves toward the clamping device 8, and the rod-shaped object is rotatably connected to the rotating plate 14. When pushed forward, the rotating plate 14 rotates with the fixed shaft 13 as the center, so that the rotating plate 14 is close to the fixed shaft 13. The side near the clamping device 8 presses the component downward, and when the rotating plate 14 rotates, the spring 15 at the lower end is squeezed, so that the spring 15 is tightened. When the air pump is not working, the spring 15 is not under force and pushes the rotating plate 14 upward, thereby facilitating the resetting of the telescopic rod 10. After the component is clamped in the clamping device 8 by the rotating plate 14, the mobile frame 5 is started. The mobile frame 5 moves left and right in the fixed frame 4 through the internal driving device, and will drive the grinding assembly 6 to move to the left end and then start. The surface of the component is polished and deburred by the grinding assembly 6. During the grinding process, the connecting pipe 804 blows gas into the clamping device 8 to blow out the debris at the grinding area.
