Multi-station circular-disc type novel numerical control automobile hub polishing machine

Abstract

The invention discloses a multi-station circular-disc type novel numerical control automobile hub polishing machine. The multi-station circular-disc type novel numerical control automobile hub polishing machine comprises a revolution circular disc assembly in the middle. Autoroatation hub clamp assemblies of multiple stations are evenly arranged on the revolution circular disc assembly in the circumferential direction at equal angles. Asynchronous polishing wheel assemblies of the stations and a loading and unloading station of one station are arranged around the autoroatation circular disc assemblies and correspond to the autoroatation hub clamp assemblies of all the stations. The polishing wheel assembly of each station comprises a three-direction displacement component and a polishing wheel machine head component deflecting at the preset angle along the horizontal axis and arranged on the three-direction displacement component. The polishing machine can achieve four-axis linkage and automatic compensation for the polishing wheel wear radius, and therefore production efficiency is improved greatly; meanwhile, the application range of complex-spoke hub polishing is enlarged, and the stable and consistent hub polishing quality is guaranteed; and the requirement on the experience of operators is lowered, and thus production efficiency and economic benefits are improved.

Description

technical field [0001] The invention relates to a numerically controlled polishing machine for automobile wheel hubs, which belongs to the technical field of polishing machine equipment, in particular to a new multi-station disc type numerically controlled polishing machine for automobile wheel hubs. Background technique [0002] At present, most of the existing car wheel polishing relies on workers holding different polishing tools to polish different parts of the rotating car wheel. There are also a few simple equipment with an electric cloth wheel, which is operated by workers to polish certain parts of the rotating wheel. The production efficiency of this manual polishing method is low, the labor intensity of workers is high, the aluminum alloy dust pollution is serious and it is easy to cause explosion accidents.

Problems solved by technology

The production efficiency of this manual polishing method is low, the labor intensity of the workers is high, the aluminum alloy dust pollution is serious and it is easy to cause explosion accidents

[0003] Although the invention patent "multi-station vertical automatic turntable polishing device" with the authorized notification number CN 102699805B discloses an automatic polishing device, it has fundamental defects: one is that the polishing wheel only moves in one vertical direction, It cannot polish workpieces with complex shapes; the second is that the polishing wheel is manually adjusted without automatic radius compensation function, and the size and surface quality of the polished workpiece cannot be guaranteed to be consistent; Polishing industry use

However, when it polishes wheels with different outer diameters, different widths and different shapes of spokes, there are major defects: one is that the polishing machine head can be adjusted in three-dimensional space X, Y, and Z, but the X, Y directions are manual, and the Z direction It is electric, and multi-axis linkage cannot be realized; the second is that the polishing head can only manually adjust the pitch angle in the Z direction plane, and cannot automatically adjust the pitch angle, and cannot adapt to the polishing of different hub spokes; the third is that the polishing head is horizontal in the Z direction. The rotation angle cannot be adjusted in the plane, and it is difficult to adapt to the polishing of different spokes of the hub; the fourth is that the polishing head cannot be parallel to the axis of the hub in the Z direction plane, and the plane polishing of the bottom of the hub cannot be performed; the fifth is that the polishing wheel can only be pressed in the Z direction. The preset wear size is used for quantitative radius compensation, which cannot realize real-time automatic compensation, and it is difficult to ensure the consistent size of the polished hub

Therefore, this kind of robot workstation not only needs the cooperation of experienced operators, but it is difficult to adjust and the polishing accuracy is low, which limits the scope of application of wheel hub polishing with multiple varieties and shapes of spokes, and cannot complete the polishing of all areas of the wheel hub within one working cycle. , thereby reducing production efficiency and increasing production costs, so the above-mentioned defects of manual or automotive wheel hub polishing robot workstations will lead to the inability to improve the economic benefits of the enterprise and limit the further development of the enterprise
