AI Technical Summary

Problems solved by technology

However, the above-mentioned rotary wire wheel brush derusting machine also has significant defects: its transmission mechanism adopts belt transmission, which is prone to slipping during start-up and grinding, which will affect the center distance of the steel brush, and the grinding amount is difficult to be consistent with expectations. It is easy to scrap the product; the center distance between the two sets of wire wheel brushes is realized by the centrifugal force generated by the rotating speed. The scope of the application is very limited and the scope of application is small

Abstract

The invention discloses a CNC (computerized numerical control) multi-axis rotary centerless cylindrical grinding machine comprising a case and a rotary working plate. The rotary working plate is driven by a hollow drive spindle and is connected with a high-speed rotating shaft displaceable within a bearing seat through a planetary gear train; a tool is arranged at exposed end of the high-speed rotating shaft; the hollow drive spindle is provided with a power drive mechanism; the high-speed rotating shaft is indirectly connected with a feeding mechanism by feed driving inner and outer gear rings, and the power drive mechanism and the feeding mechanism are connected with an electrical control system controlling difference. Workpiece rotational motion form and processing ideas of traditional cylindrical grinding machine are changed, and the CNC multi-axis rotary centerless cylindrical grinding machine has the advantages that the problem that too long or too big workpiece is hard to processed is solved, surface mechanical descaling of metal rod linear materials is achieved, CNC operation is also achieved, and control and processing precision are improved, cost is reduced, and energy conservation and emission reduction are realized, and consequently having profound meaning and effect in protecting environment for human survival and having better popularization and use values.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing metal product processing equipment, in particular to a numerically controlled multi-axis rotary centerless cylindrical grinding machine. Background technique [0002] In the prior art, ordinary conventional standard cylindrical grinders and centerless cylindrical grinders require the processed round bar material to rotate by itself to perform grinding processing. To process ultra-long and ultra-fine linear metal materials, the machine must rotate It is almost impossible to keep the movement stable, especially for the precise grinding of the outer circular surface of thin and long linear metal materials with small and medium diameters (?40mm-?8mm) but hundreds or thousands of meters in length, it is very difficult It can be realized by fixing the clamp, but the surface of the wire rod needs to be derusted before the metal wire drawing forming process. At present, the methods used f...
