Method and device for measuring eccentric distance of small pole

Abstract

The invention relates to a method and a device for measuring the eccentric distance of a small pole. In the method for measuring the eccentric distance of the small pole, a rolling unit, an image pickup unit and an image processing unit can be used for measuring the eccentric distance of the small pole to be measured. The method for measuring the eccentric distance of the small pole disclosed by the invention comprises the following steps of: putting the pole body of the small pole to be measured onto the rolling unit, and rotating the small pole to be measured around a pole axle center of the pole body; continuously picking up a plurality of image data by using the image pickup unit, and transmitting the image data to the image processing unit; calculating an approximate circle by using the image processing unit, wherein the circle center of the approximate circle is equivalent to the position of the pole axle center; and displaying the length of an approximate circle radius of the approximate circle on a display module of the image processing unit, wherein the length of the approximate circle radius is the eccentric distance of the small pole to be measured.

Description

technical field [0001] The invention relates to a measurement method and a measurement device, in particular to a method for measuring the eccentric distance of a rod and a device for measuring the eccentric distance of the rod. Background technique [0002] General rods, such as long nails, screws or shafts, etc., have a shaft and an end face, and in order to achieve good installation accuracy and smooth operation, a center point of the end face must be precisely located on the rod. on the axis of the body. Taking screws as an example, they all include an elongated shaft, a screw head connected to one end of the shaft, and a working groove recessed from the surface of the screw head. The working slot can provide tool clamping and is installed in a rotating manner. Therefore, the center point of the working slot and the shaft center of the shaft must be on the same straight line, so that the screw can be installed stably and accurately. In order to make the center point of...

Problems solved by technology

However, when the size of the working trough is small, the accuracy will be insufficient because the probe is not fine enough. In addition, when the shape of the working trough is more complex, the complexity of the calculation of the data is also increased, and a large amount of time must be spent to calculate , therefore, the traditional measurement method of eccentric distance has the disadvantages of insufficient accuracy and low efficiency

[0004] It can be seen that the above-mentioned existing rod eccentric distance measurement method and rod eccentric distance measurement device obviously still have inconveniences and defects in terms of method, product structure and use, and need to be further improved urgently.

In order to solve the above-mentioned existing problems, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable method and structure for general methods and products to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
