CCD full automatic high-precision needle grinding machine and needle grinding control method

Abstract

The invention relates to a full automatic needle grinding technology, in particular to a CCD full automatic high-precision needle grinding machine and a needle grinding control method. The method comprises the following steps: step 1) obtaining the coordinates of a workpiece; step 2) shifting a grinding wheel to the tool setting position; step 3) initially positioning the grinding wheel; step 4) finely positioning the grinding wheel; step 5) initially processing the workpiece; step 6) finishing the workpiece; and step 7) polishing the workpiece. The needle grinding machine comprises a base, and a position adjusting device disposed on the base, wherein the position adjusting device includes a Y-axis moving mechanism, and an X-axis moving mechanism disposed on the Y-axis moving mechanism; apunch pin holding mechanism is disposed at the rear end of the Y-axis moving mechanism; the punch pin holding mechanism is provided with a CCD camera capable of scanning a thick needle; the CCD camerais connected with an industrial computer; and the X-axis moving mechanism is provided with a primary grinding mechanism and a fine grinding mechanism in mutual perpendicular arrangement along a horizontal square shaft. The invention improves the precision of the grinding of the product and realizes the purposes of automatic precise positioning and grinding.

Description

technical field [0001] The invention relates to a full-automatic needle grinding technology, in particular to a CCD full-automatic high-precision needle grinding machine and a needle grinding control method. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the manufacturing industry has also flourished. The diameter of the working part of the spinneret spinneret finishing punching needle is (0.1-0.04mm) and the shape is arc and straight. Composed of oblique lines, the material of the punching needle is hard alloy and high-speed steel, and it is easy to break when the diameter is 0.015mm when it is ultra-small. As a very important processing and production device, the needle grinding device needs more technical support and method quality improvement. However, in the traditional processing and preparation, some rough grinding devices on the market can only grind straight lines. And slash fox is impo...

Problems solved by technology

As a very important processing and production device, the needle grinding device needs more technical support and method quality improvement. However, in the traditional processing and preparation, some rough grinding devices on the market can only grind straight lines. and slash fox is impossible to complete

The arc can only be polished by hand under a microscope

This method does not use the production line to work, and it poses hidden dangers to the safety of employees. Secondly, for high-precision processing originals such as punching needles, the traditional technology uses a microscope to manually observe and position, and the manual observation position is not accurate. Not only is the accuracy poor but also The operation is labor-intensive, and this processing method can only meet some parts that do not require high precision.

[0003] However, in the traditional processing and preparation, there are many defects that need to be improved in the grinding of the grinding device. There are some grinding devices on the market now. For high-precision processing parts such as punching needles, the traditional technology uses human observation and positioning. The manual observation position is not accurate, not only poor precision but also labor-intensive operation. This processing method can only meet some parts that do not require high precision.
