Grinding attachment suitable for freely curved face

Abstract

The invention relates to a grinding device applicable to free-form surfaces. A workpiece table is supported on an X-axis guide rail of the upper surface of an X-axis bed. A Y-axis bed is arranged adjacent to the X-axis bed, and the upper surface of the Y-axis bed supports a Z-axis bed through a Y-axis guide rail. Two Z-axis guide rails are arranged on the surface of the Z-axis guide rail facing toward the X-axis bed. A slide plate is supported on the guide rail. The slide plate is connected with the gear on a B-axis rotary motor output axis through a B-axis rotary supporting body. A C-axis driving motor is arranged at the top of a rotary seat. A driving gear sleeved on the output axis of the C-axis driving motor is meshed with a driven gear. The driven gear is fixedly connected with the C-axis rotary axis which is provided with a grinding head seat. A grinding head motor is arranged on the upper end of the grinding head seat, and a contact wheel is arranged at the bottom of the grinding head seat. The contact wheel is connected with a driving wheel on the output axis of the grinding head motor through an abrasive belt. The device can realize the grinding treatment of complex curved surface workpieces by the combination of six degrees of freedom of space, thereby effectively improving the polishing precision and surface quality of the workpieces.

Description

technical field [0001] The invention relates to a grinding device suitable for free curved surfaces, which is suitable for grinding parts with complex curved surfaces. Background technique [0002] At present, most of the grinding and polishing processes for workpieces with complex geometric shapes (aviation blades, steam turbine blades, human joints, sanitary ware, etc.) Bad and other disadvantages, while high management costs. Although this polishing method can realize the grinding and polishing of complex curved surfaces, it cannot effectively control the dimensional accuracy, resulting in poor processing accuracy and difficult to guarantee the quality of the surface, and the quality of the curved surface is different from the proficiency of the operator. It has a lot to do with it, not only the labor intensity of the workers is high, but also the situation of uneven grinding thickness in surface polishing cannot be effectively solved.

[0002] At present, most of the grinding and polishing processes for workpieces with complex geometric shapes (aviation blades, steam turbine blades, human joints, sanitary ware, etc.) Poor and other disadvantages, while high management costs

Although this polishing method can realize the grinding and polishing of complex curved surfaces, it cannot effectively control the dimensional accuracy, resulting in poor processing accuracy and difficult to guarantee the quality of the surface, and the quality of the curved surface is different from the proficiency of the operator. It has a lot to do with it, not only the labor intensity of the workers is high, but also the situation of uneven grinding thickness in surface polishing cannot be effectively solved

On the basis of the traditional machine tool design, the German metabo company has developed a professional blade grinding machine tool, which greatly improves the grinding efficiency of the blade. However, the main plane of the Z-axis of the equipment is not parallel to the X-axis, and is in a vertical state, causing the grinding head to The rotating support arm around the Y axis is too long, the rigidity is not good, and it cannot meet the requirements of large feed grinding of the blade profile

Domestic Hebei Langfang Zhitong Robot Co., Ltd. cooperated with ABB to develop the robotic arm, which realized the automation of complex shape workpiece grinding and polishing, improved the yield rate, and shortened the processing time. However, because the equipment adopts a series manipulator structure, the rigidity of the equipment is very high. Poor, unable to adapt to the functional requirements of fast grinding of large blades
