Referring to FIGS. 1 and 2 and FIGS. 6-7, the fixing base 41 is fixed to the platform device 32 of the third-dimensional measuring bed 3, and the standard rod 42 is mounted in the fixing base 41 (head or tailstock). When assembling the machine tool, it is used as a fixture for testing purposes. Because the standard rod 42 is a cylinder, the arc vertex is not easy to identify, and the surface is a polished smooth surface 421. The laser is difficult to interpret, so the two flats are milled on the cylinder. Improve the accuracy of the measurement.

With the combination of the above components, the first embodiment of the present invention, and referring to FIGS. 1 to 3, first, the light source unit 1 is mounted on a feeding device 31 having at least an X-axis and a Y-axis and can be automatically controlled by a program. The fixing base 41 is placed on the platform device 32, and then it is confirmed whether the fixing seat 41 to be measured is within the focal length of the projection beam of the light source unit 1 (ie, within the measurable range of the projection beam of the laser displacement meter) After determining the detection range of the light source unit 1, further setting the area of the pre-measurement fixing base 41 and the standard rod 42 and the path code for processing the measurement area at the control end of the feeding device 31, in the code writing and After the setting is terminated, the path program is executed, and the feeding device 31 will automatically move according to the executed path.

The second embodiment of the present invention is characterized in that the platform device 32 of the three-dimensional measuring bed 3 can set the working path according to the program to drive the mounting surface 411 of the fixing base 41 and the surface of the standard rod 42 to be projected by the light beam; and the feeding device 31 is assembled on the platform device 32 and used to fix and drive the light source unit 1. Thereby, the platform device 32 can reciprocate the fixing base 41 and the standard rod 42 along the light source unit 1 to achieve the installation of the fixing base 41. The purpose of surface 411 and standard rod 42 surface profile scanning.

Please refer to FIG. 8 , which is the flow of the steps of the creation: the process 91, the standard rod 42 is mounted in the fixing base 41 and placed on the platform device 32 of the three-dimensional measuring bed 3; In the process 92, the adjustment of the light source level device 2 is used to correct the assembly error; in the flow 93, the light source unit 1 projects a light beam to scan the surface of the fixed base 41 and the standard rod 42; and the process 94 captures the surface of the fixed base 41 and the standard rod 42. The original parameter value of the precision; the process 95, calculating the inclination trend line and the angle of the original parameter value, and compensating the parameter of the original parameter value; the process 96, establishing the high and low distribution type of the surface precision according to the corrected parameter; The angle parameter of the standard rod 42 and the mounting surface 411 of the fixing base 41; the flow 98, by detecting whether the angle parameter meets the accuracy and the design requirement condition, is executed in the flow 99, otherwise returns to the flow 93; the flow 99, and the scanning operation is ended.

This creation uses a bow path for step displacement scanning in the scan path design, and can also perform any path editing on the path program according to requirements, such as the mounting surface 411 of the intermittent or continuous displacement measuring mount 41 and the standard rod 42. The surface is activated by the computer application language to cooperate with the data capture device 61 to set the capture frequency before the movement of the feed device 31 is performed, and is also captured by the data capture device 61 while the feed device 31 is moving. The parameter is recorded and recorded, and the linked data capturing device 61 performs the grasping action to access the scanned by the light source unit 1. Parameter value.

Referring to FIG. 9, after the path scan is completed, the data capture device 61 stores the displacement values of one piece into a parameter value, and then uses the self-developed program (Visual C++ MFC) to perform the drawing operation processing, and the written MFC program. The displacement value of each line is automatically fitted to the surface, and then the computer 6 performs the arithmetic processing to obtain the inclination angle of the mounting surface 411 of the fixing seat 41 and the standard rod 42, and it is clear It is known how much the flatness of the mounting surface 411 of the scanning mount 41 and the surface of the standard rod 42 is flat.

Referring to FIG. 10, the operation processing unit and the drawing interface of the parameter value are adjusted by using the parameter adjustment device 62 containing the programming language. The parameter adjustment device 62 first reads out the parameter values in the data extraction device 61 due to the scanned workpiece. There is an angle of inclination (as shown in Annex 1). Therefore, we must first calculate the sloped trend line for each original parameter value, and then correct each original parameter (as shown in Attachment 2), and place all the parameter values after each correction in one parameter file. After the value is corrected, the height and distribution pattern of the surface accuracy of the mounting surface 411 of the fixing base 41 will be drawn; after the parameter adjustment device 62 selects the high and low distribution pattern, the measurement range of the X axis and the Y axis is input. The measurement range can be set according to the requirements, and the Z axis needs to click the link parameter after the correction. After the selected computer 6 draws the graph according to the parameter file, the high and low distribution pattern can be drawn.

In the aspect of high and low profile pattern drawing, add Z-axis depth color change It can be seen that the height fluctuation of the plane can be seen in the high and low distribution pattern. As shown in the attachments 1 to 2, it is the height distribution map and angle calculation result of the surface of the mounting surface 411 of the fixing base 41. The height and low fluctuation of the mounting surface 411 of the fixing base 41 can be clearly seen from the above description. When the detecting seat 41 and the standard rod 42 are detected, the scanning pattern and the calculated tilt angle of the high and low profile patterns can be used. It is convenient for the shovel manufacturer to know how much the surface of the mounting surface 411 of the fixing base 41 is undulating, and where the shovel action needs to be performed, and the inclination angle of the standard rod 42 is used to determine how much height the mounting surface 411 of the fixing base 41 needs to be removed. Instead of using a traditional smudge developer and contact inspection.

It is worth noting that the parameter value of the Z-axis of this creation does not have a correction operation for each pen. The correction parameter is the actual parameter value measured by the light source unit 1. When the fixed seat 41 is tilted, the correction action is performed, if the fixed seat 41 is not tilted, the parameter value of the Z axis will not need to be corrected.
