Problems solved by technology

The holes on the equipment have high precision during manufacturing and processing, but due to the special shape of the holes during installation and alignment, it is necessary to use a steel ruler to divide the holes and pull them to the reference line for measurement, and the height of the horizontal holes cannot be accurately measured. Factors and human factors have caused the measurement accuracy of the hole center position to be low
Therefore, the equipment that uses the equipment hole center as the alignment reference needs to be further adjusted through other reference planes to achieve accuracy and meet the process requirements. Such a process requires more work time

Embodiment Construction

[0018] The present invention is further illustrated below by specific examples.

[0019] Such as figure 1 , figure 2 As shown, a method of using a total station to accurately detect the hole position of the equipment, including

[0020] Step 1. After the equipment is in place, make initial adjustments according to the drawing size.

[0021] Step 2. Set up the total station to the position where the hole position of the equipment can be seen through, and use the free station method to set up the station based on the pre-arranged three-dimensional control network.

[0022] Step 3. Use the spherical prism 1 and the matching magnetic base 2 to measure the three-dimensional coordinates of the pin holes 3 and 4. The measurement method is to attach the spherical prism 1 to the magnetic base 2, and use the The straight rod is close to the inside of the edge of the pin holes 3 and 4, and then the total station is used to measure the spherical prism to collect and record the three-d...

Abstract

The invention relates to a method for accurately detecting a hole site of equipment by using a total station. The main to-be-solved problem is how to use advanced measuring instruments and methods toimprove the measurement accuracy of the hole site of a connection part of the equipment, avoid the precision loss caused by manual drawing of a steel tap, and accurately adjust the steel tap in placebefore the equipment is connected, thereby improving the installation efficiency and shortening the adjustment cycle of the equipment.

Description

technical field [0001] The invention relates to the field of equipment installation, in particular to a method for accurately detecting equipment hole positions using a total station. Background technique [0002] In the installation of large-scale electromechanical equipment, the movable parts and fixed parts of the equipment are often connected by pin shafts, and the equipment and the base are also connected by fixed pins. Whether the position of the pin hole is correct is related to the positional accuracy of the equipment after connection. The holes on the equipment have high precision during manufacturing and processing, but due to the special shape of the holes during installation and alignment, it is necessary to use a steel ruler to divide the holes and pull them to the reference line for measurement, and the height of the horizontal holes cannot be accurately measured. Factors and human factors cause the measurement accuracy of the hole center position to be low all...
