Description

Technical Field

[0001] The invention relates to a laser target two-dimensional reading measurement platform. Background Art

[0002] As a high-precision optical measurement tool, laser beam instruments are widely used in industrial manufacturing, construction engineering, and mechanical processing. Their core function is to calibrate and detect spatial straightness, flatness, or angle parameters by emitting a high-stability laser beam. Under the traditional technical framework, the calibration process of such instruments is highly dependent on manual operation and empirical judgment, resulting in low efficiency and poor repeatability. The typical calibration process requires the instrument to be fixed by a mechanical fixture and calibrated with the help of an external reference reference (such as the line scale method, see Chinese patent CN201910827911.4, the parallel light tube method, and the photosensitive screen digital method). During this process, the laser line and the target reference must be observed by the naked eye to see how well they match, and the deviation data is read out and then calibrated. When reading, since it is necessary to read the scale on the scale with the laser, it is very easy to cause reading deviations due to visual errors or ambient light interference. In addition, the traditional calibration method can only calibrate the X direction or the Y direction alone, and cannot be calibrated at the same time, so there is naturally a certain system error.

[0006] How to use this platform: Take four platforms and install them on the reference wall. The four platforms are arranged in a cross direction on the wall. The one at the top is marked as platform 1, the one at the bottom is marked as platform 2, the one at the far left is marked as platform 3, and the one at the far right is marked as platform 4. Calibrate them with the reference markings (after being irradiated by the standard cross laser line, the X axis of the cross laser line just passes through the center of the cross target of platform 3 and platform 4, and the reading of the second differential cylinder of platform 3 and platform 4 is zero. Similarly, the Y axis of the cross laser line just passes through the center of platform 1 and platform 2). The center of the cross target on the platform, the reading of the first differential cylinder corresponding to the No. 1 platform and the No. 2 platform is zero), the device to be tested irradiates the reference wall at the specified position to lay out the line, and the X-axis and Y-axis of the cross laser line will fall on the target plates of the four platforms. If the laser line is not aligned with the center of the cross target on the corresponding target plate, it means that the device has been offset. At this time, the X-axis and Y-axis of the cross laser line are realigned with the center of the cross target on the corresponding target plate by adjusting the corresponding first differential cylinder and the second differential cylinder, and then the differential cylinders are read respectively to obtain the offset of the horizontal laser line and the vertical laser line.

[0007] Advantages of this platform: This platform has accurate measurement and simple operation. The offset is accurately measured with a differential cylinder for easy reading. It can also measure the X-axis and Y-axis at the same time with high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
