Embodiment Construction

[0029] The present invention researches the method of measuring the curvature of the plate, and invents a new type of contact measuring device for the curvature of the plate for the roll bender, that is, the three contacts of the measuring device are in contact with the plate, and the measurement of both sides can be measured through the angle encoder The angle of the point relative to the middle point, where the distance between the measurement points on both sides and the middle point is a fixed value, calculated by trigonometric functions, the radius of curvature of the plate forming can be obtained.

[0030] The innovative specific implementation of the present invention will be further described below in conjunction with the implementation examples and the accompanying drawings.

[0031] The novel plate curvature contact measuring device (hereinafter referred to as the measuring device) provided by the present invention has a structure such as figure 1 and figure 2 As s...

Abstract

The invention discloses a novel plate curvature contact measuring device.Vertical motion of the device is interactively controlled by two servo motors, three cams of the measuring device make contact with a plate to be measured, the angles of measuring points on the two sides of the plate to be measured relative to a middle point of the plate are measured by an angle encoder, the distances between the two-side measuring points and the middle point are constant values, and the plate forming curvature radius is obtained through trigonometric function calculation.Compared with other plate curvature measuring devices, the novel plate curvature contact measuring device has the advantages of beings simple in structure, high in measuring speed and precision, capable of achieving plate processing automation and being not influenced by the plate surface condition and the processing environment and the like.

Description

technical field [0001] The invention relates to a novel plate curvature contact measuring device, in particular to a three-point contact plate curvature contact measuring device, which belongs to the field of plate bending automation. Background technique [0002] Sheet metal bending is a relatively common sheet metal forming processing method, which is widely used in various industries such as aviation, shipbuilding, boilers, and chemicals. However, due to some problems in the automatic control process of the roll bender, the operation of the roll bender is still limited to the manual guidance of processing, and the processing mode of automatic control has not been formed. Compared with other processing methods that have already realized automatic control, manual sample checking is not only inefficient and poor in precision, but also consumes a lot of materials and man-hours for the production of samples. At the same time, the manual inspection method also restricts the aut...
