Two-wheeled numerical control roll grinder and numerical control method thereof

Abstract

The invention discloses a two-wheeled numerical control roll grinder and a numerical control method thereof. A small sliding frame of the double-wheeled numerical control roll grinder is provided with a U-axis micro-feeding mechanism, a main mechanical transmission case is lubricated by adopting an active lubricating loop, a cooling water purifying device is arranged on a grinder body, a large sliding frame guide rail is connected with a Z-axis guide rail hydraulic station through a lubricating oil tube, the Z-axis guide rail hydraulic station is subjected to dynamic pressure lubrication, a grinding wheel and an abrasive belt wheel are respectively connected with a shared mainshaft hydraulic station, a hybrid bearing and a capillary tube adjuster are respectively arranged at the front and the back of a main shaft of the grinding wheel and a main shaft of the abrasive belt wheel, and the mainshaft of the grinding wheel and the mainshaft of the abrasive belt wheel are subjected to dynamic and static pressure lubrication. According to the invention, due to adoption of a numerical-control setting manner, a roll curve is easy to change, ground workpieces are higher in quality and are easy to automatically control, the manual misoperation probability is lowered, a very excellent repeatable machining purpose is achieved and the quality of batch production can be ensured.

Description

technical field [0001] The invention relates to a roll grinder, in particular to a double-wheel numerically controlled roll grinder and a numerically controlled method thereof. Background technique [0002] The double-wheel roll grinder is a kind of roll processing equipment commonly used in the paper industry. It has two grinding wheels, one is a grinding wheel, which is used to grind the roll, and the other is a belt wheel, which drives the belt to move , Complete the fine grinding and surface polishing treatment of the roll, which can improve the smoothness of the roll and make the processed roll more accurate. However, the traditional two-wheel roll grinder generally adopts DC speed regulation and relay logic control, and uses the method of mechanical profiling to grind and process simple convex (or concave) roll-shaped curved rolls, which is difficult to process modern rolls. The different curves of the roll surface, and the traditional mechanical transmission structur...

Problems solved by technology

However, the traditional two-wheel roll grinder generally adopts DC speed regulation and relay logic control, and uses the method of mechanical profiling to grind and process simple convex (or concave) roll-shaped curved rolls, which is difficult to process modern rolls. The different curves of the roll surface, and the traditional mechanical transmission structure can not meet the requirements of CNC machine tools, so it is urgent to carry out mechatronics transformation on the existing old double-wheel roll grinder, so that it has the CNC processing ability and improve the application of the grinder scope
