Novel high-accuracy numerical-control gear-forming gear grinding machine and operating method thereof

Abstract

The invention discloses a novel high-accuracy numerical-control gear-forming gear grinding machine and an operating method thereof. The novel high-accuracy numerical-control gear-forming gear grinding machine comprises a machine body, a tool rest, an X feeding sliding rail, a longitudinal feeding sliding rail, a cube boron-nitride grinding wheel, a grinding wheel rotating shaft, a Y feeding sliding rail, a moving carrying table, a circular magnetic grid, a rotating table, a fixing part, a screw, a linear magnetic grid, a magnetic ruler and a conveying cable. The novel high-accuracy numerical-control gear-forming gear grinding machine has the beneficial effects that controllability is high; as the rotating table is provided with the circular magnetic grid, accurate angle monitoring and feeding can be achieved; the moving carrying table is provided with the linear magnetic grid and the magnetic ruler, so that displacement in the Y direction is detected; the grinding wheel rotating shaft is provided with a speed detection sensor, so that the rotating speed is fed back in real time, and accurate control over the rotating speed is guaranteed; as the rotating table is provided with the fixing part and the screw, and a to-be-machined object is placed on the rotating table to be fixed, the object can be machined, operation is convenient, and efficiency is high; and the sensor can carry out real-time feedback to achieve accurate closed-loop control over feeding, rotating and the speed.

Description

technical field [0001] The invention relates to a numerically controlled gear grinding machine, in particular to a high-precision numerically controlled gear forming gear grinding machine and an operating method thereof, belonging to the field of mechanical processing equipment. Background technique [0002] With the birth of CNC machine tools, the mechanical processing industry has undergone earth-shaking changes, and the gear processing industry has also produced higher and stricter requirements. The traditional gear processing has low efficiency, complicated operation, and poor controllability, requiring experienced operators. It can only be processed, the processing rate is very low, it is difficult to meet the increasingly stringent machining requirements, and the feed speed of the workpiece and the speed of the grinding wheel shaft are mostly controlled by open-loop control, without feedback components, it is easy to cause the speed to be too high or too high.

[0002] With the birth of CNC machine tools, the mechanical processing industry has undergone earth-shaking changes, and the gear processing industry has also produced higher and stricter requirements. The traditional gear processing has low efficiency, complicated operation, and poor controllability, requiring experienced operators. It can only be processed, the processing rate is very low, it is difficult to meet the increasingly stringent machining requirements, and the feed speed of the workpiece and the speed of the grinding wheel shaft are mostly controlled by open-loop control, without feedback components, it is easy to cause the speed to be too high or too high. The situation that the workpiece is scrapped is low, and most of the traditional gear processing devices are only set scales, and then manually adjusted, the precision is very low. Many gear processing equipment only use tools and grinding wheels that can move in a straight line, while clamping to be processed The device of the workpiece can only rotate, and the strain resistance is poor
