Description

Technical Field

[0001] The utility model relates to the field of deburring devices, in particular to a deburring device for the casting end cover of a hydraulic generator set. Background Technique

[0002] The casting end cover of a hydraulic generator set is a crucial component in the generator set. It not only serves as part of the generator housing but also undertakes the key function of the bearing seat. These end covers are made through a precise casting process. After the end cover casting is completed, to ensure the accuracy of the end cover, a deburring device is required to remove the burrs remaining on the inner and outer surfaces of the end cover.

[0003] Chinese Patent (Publication No. CN118181044A) discloses a deburring device, which includes a workbench, and also includes a grinding component, a chip collection component, and a transportation component; the grinding component includes a grinding piece; a chip collection groove is formed on the workbench, and a placement table is arranged above the chip collection groove; the chip collection component includes a blower, a chip collection pipe, and a chip collection box; the blowing direction of the blower faces the chip collection groove; the chip collection pipe is communicated with the chip collection groove; the chip collection box is detachably connected to the workbench, and the interior of the chip collection box has a chip collection space, and the bottom of the chip collection pipe is communicated with the chip collection space; the transportation component includes a frame, a plurality of rotating rollers, a plurality of driving components, and a transportation belt; and the plurality of driving components can drive the plurality of rotating rollers to rotate, which can not only effectively improve the efficiency of deburring treatment of metal workpieces but also reduce the impact of metal chips generated by deburring treatment on the environment and workers. However, there are still the following deficiencies.

[0004] The inner and outer surfaces of the existing casting end covers of hydraulic generator sets are usually irregular planes. The existing deburring devices usually fix the end cover on the surface of the workbench, and then drive a high-speed rotating abrasive to move downward through a telescopic device to make the abrasive close to the surface of the workpiece to remove the burrs remaining on the surface of the workpiece. However, the existing burr devices can only move vertically or horizontally. When deburring workpieces with irregular surfaces, there will still be some burrs remaining and they cannot be completely removed. As a result, the deburring device cannot meet the work of removing burrs remaining on irregular surfaces. Therefore, the inventor proposes a deburring device for the casting end cover of a hydraulic generator set to solve the above problems. Summary of the Invention

[0005] To solve the above problems, a deburring device for the casting end cover of a hydraulic generator set is provided. By placing the workpiece on the upper end surface of the annular feeding table, the clamping rod is driven by the second telescopic component to move horizontally along the limiting groove, thereby fixing the workpiece. Then, several telescopic first telescopic components are movably arranged inside the rotating device, and the output end of the first telescopic component is installed on the lower end surface of the annular feeding table, so that the rotating device drives the annular feeding table to rotate through the first telescopic component. At the same time, the first telescopic component drives the edge of the annular feeding table to be able to float up and down to form a wavy movement track, thereby adjusting the machining angle of the workpiece. The deburring device can remove the burrs remaining on the inner and outer irregular surfaces of the casting end cover of the generator set, thereby improving the machining efficiency and solving the problem that the deburring device cannot remove the burrs remaining on the irregular surfaces.

A first gear capable of meshing with the third toothed belt is installed outside the output end of the first rotation driving part, so that when the first rotation driving part drives the first gear to rotate, the annular frame is driven to rotate through the third toothed belt.

[0009] As a technical solution of the present utility model, a storage tank is provided at the center of the lower end surface inside the workbench. A sand feeding device is arranged on one side of the storage tank so that the sand feeding device can output the sand inside the storage tank.

[0010] As a technical solution of the present utility model, a funnel is installed on the upper end surface inside the workbench, and the output end of the funnel is butted against the input end of the storage tank so that the sand grains generated during deburring processing can be conveyed into the storage tank through the funnel.
