Problems solved by technology

[0005] Although the first method can obtain a certain processing accuracy, the cost of introducing ultra-precision equipment (such as diamond car, ultra-precision grinding machine, polishing machine, RAPT machine, etc.) is high, and the independent research and development time is long and the cost is high.
The second method can also obtain a certain processing accuracy, but the quality of the workpiece mainly depends on the technical level of the workers, the trimming time is very long, and the efficiency is low

Embodiment Construction

[0040] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0041] like figure 1 As shown, it is the basic principle based on the arc trimming algorithm of a rotary part disclosed in the present invention. After the workpiece has been roughly ground, the original contour error is measured, trimmed according to the error, and then measured and trimmed until the workpiece The accuracy meets the requirements.

[0042] The arc trimming algorithm of rotary parts provided by the present invention can run on such figure 2 In the control system shown, the system includes a computer running the algorithm for arc trimming of rotary parts. The computer is connected to a frequency converter and a motion control card. The frequency converter is connected to a variable frequency motor. The workpiece is driven to rotate by the dial, and the rotary encoder records the number of rotations of the workpie...

Abstract

The invention provides a rotary part arc trimming algorithm. The rotary part arc trimming algorithm is characterized by comprising the steps that parameters are initialized; roundness measurement is carried out; a roundness error is evaluated; angular speeds of trimming joints are determined; the motor rotating speed control pulse number which should be input for controlling the motor rotation is obtained, an indexing angle alpha is converted into a control angle of the motor, and then the control angle of the motor is converted into a corresponding motor angle control pulse number; and the motor controls a trimming tool to complete trimming of a workpiece to be trimmed according to the motor rotating speed control pulse number and the motor angle control pulse number. According to the other technical scheme, the invention provides a rotary part arc trimming control system using the rotary part arc trimming algorithm. According to the invention, on the premise that rotary part arc trimming cost is reduced, the roundness error can be rapidly converged; and the rotary part arc trimming algorithm and the rotary part arc trimming control system have the beneficial effects of being low in cost, high in efficiency and intelligentized.

Description

technical field [0001] The invention relates to a low-cost, high-efficiency and intelligently controlled arc trimming algorithm for rotary parts and a control system thereof, belonging to the technical field of precision machining. Background technique [0002] Rotary parts are one of the most typical types of machine parts, and they are widely used, such as drive shafts and support shafts in machine tools, automobiles, aircraft, internal combustion engines, engines, agricultural machinery and military machinery, and inner and outer rings of bearings , cams and some cover parts, etc. With the continuous development of modern industry, the precision requirements for rotary parts are getting higher and higher, especially the shape precision of the supporting journal. People pay more and more attention to precision machining technology, precision machining equipment and precision measurement of rotary parts. At present, there are two main ways for ultra-precision machining of...
