Five-axis numerically-controlled grinding device

Abstract

The invention discloses a five-axis numerically-controlled grinding device, and belongs to the technical field of numerically-controlled lathes. The five-axis numerically-controlled grinding device comprises a cross beam sliding seat driven by a first power device and mounted on a cross beam along the X-axis in a sliding manner; a rotating sliding seat driven by a second power device and rotating along the B-axis is arranged on the cross beam sliding seat; a ram driven by a third power device and sliding along the Z-axis is arranged on the rotating sliding seat; a first tapered sleeve driven by a fourth power device and rotating along the C-axis is arranged on the ram; a second tapered sleeve driven by a fifth power device and rotating along the A-axis is arranged on the first tapered sleeve; a grinding power head is mounted on the second tapered sleeve; the B-axis is perpendicular to the plane where the X-axis and the Z-axis are positioned; the C-axis is perpendicular to the B-axis; the A-axis is perpendicular to the C-axis; and when the B-axis returns to zero, the X-axis is perpendicular to the Z-axis. The processing to a crossed guide rail, various planes and a taper face is achieved through once clamping, interpolation is not required, the processing efficiency is high, the processing precision is high, and meanwhile, the structure is compact, the action is quick and reliable, the application range is wide, and high cost performance is achieved.

[0002] With the rapid development of the global machinery manufacturing industry and the increasing requirements for machining accuracy, machine tool equipment has become numerically controlled, intelligent, and efficient, and it is a special type, especially the high-precision grinding machine for end products, which is particularly specific and expensive. Expensive. At present, the grinding forms used in the field of machine tools at home and abroad are mostly special surface grinders, special internal and external cylindrical grinders and grinding function assemblies. In the process of manufacturing, they all have a single function, that is, a single plane or conical surface. Processing, to complete the processing of the workpiece requires multiple clamping, and then multiple clamping leads to a decrease in machining accuracy and affects processing efficiency

For example, when processing cross guide rails, it needs to be clamped multiple times; for example, when processing large cone surfaces and large V-shaped surfaces, interpolation is required, and the processed surface is rough and the precision is low.

At the same time, there is a defect of high price. Except for those that require extreme investment, most manufacturers avoid investment in grinding machine tools due to high prices, which affects the improvement of precision in the machinery manufacturing industry.

[0003] At the same time, most grinding wheel dressers of grinding machines are installed on the grinding head at this stage. Not only is the structure complex, limited by the installation position, but also the dresser rigidity is poor. Increase
