Problems solved by technology

[0004] The purpose of the present invention is to solve the problems such as the difficulty in using the commonly used prism triangular support when performing bolt positioning measurement, large fluctuations in measurement and positioning control accuracy, and low measurement and positioning efficiency. It provides a fast and accurate positioning method for prisms. The prism is supported, on the other hand, the prism can be positioned accurately, and the efficiency and accuracy of positioning measurement can be improved.

Embodiment Construction

[0023] Such as figure 1 , 2 , 3, a fast and precise bolt positioning method, comprising the following steps:

[0024] 1) Making a prism bracket: the prism bracket includes a parallel upper steel plate 3 and a lower steel plate 6, and a connecting rod 5 fixedly connected between the two steel plates and perpendicular to the two steel plates, the upper steel plate 3 and the lower steel plate 6 Respectively have a center hole (the size of the center hole of the upper steel plate is the same as the fixed bolt hole of the prism base, and the size of the center hole of the lower steel plate is slightly larger than the diameter of the bolt), the center connection line between the center hole of the upper steel plate 3 and the center hole of the lower steel plate 6 and the two steel plate vertical;

[0025] 2) Fix the prism bracket on the bolt 8 to be tested through the upper and lower nuts 7: first screw a nut on the bolt 8 to be tested, and then put the center hole of the steel pl...

Abstract

The invention discloses a method for quickly and accurately positioning a bolt. The method comprises the following steps of manufacturing a prism support; fixing the prism support on the bolt to be measured through an upper nut and a lower nut; fixing a prism on a prism substrate; fixing the prism substrate on the support through a prism substrate fixing bolt; adjusting the prism substrate to enable the center of the prism to be aligned to the center of the bolt; and using a total station to measure the position of the bolt. According to the method, the bolt can be positioned and measured quickly and efficiently, accuracy control for bolt measuring can be guaranteed, and besides, the measuring control efficiency is greatly improved.

Description

technical field [0001] The invention relates to a method for high-precision installation and positioning of pre-embedded bolts on a circular arc-shaped foundation of a certain large-scale deep space detection radar antenna equipment, in particular to a method for fast and accurate positioning of bolts. Background technique [0002] With the development of national defense modernization, the installation accuracy of high-end, precision and cutting-edge equipment is getting higher and higher, especially for the installation of large-diameter radar antennas and other equipment built in recent years. The installation accuracy is required to be high, the overall levelness is not more than 3mm, and the concentricity is 2mm. Therefore, as the main link of precision control, it should be done more finely to meet the requirements. [0003] There are a total of 472 pre-embedded bolts in the wheel-rail foundation of a deep-space exploration radar station, which are distributed alterna...
