Problems solved by technology

The ruler usually used for leveling is only an ordinary straightedge with a blister level, without any leveling mechanism, and reads by aiming at the engraved line on the body of the ruler. The aiming accuracy is very low, which greatly reduces the accuracy of the final flatness detection data

[0030] like figure 1 and figure 2 As shown, it is the first embodiment of the optical scale of the present invention. The optical scale of the present invention includes a base 1 and a ruler body 2 vertically arranged on the base 1. A fixing screw 3 is provided on the bottom surface of the base 1, and the fixing screw 3 Located directly below the ruler body 2. The other end of the base 1 away from the ruler body 2 is provided with two adjustment screws 4, and the two adjustment screws 4 are symmetrically distributed on both sides adjacent to the base 1, and the connecting line of the two adjustment screws 4 is perpendicular to the ruler body 2. , The upper surface of the base 1 is also provided with a bubble level 5 to facilitate the leveling of the base 1 .

[0031] The upper part of the ruler body 2 is covered with a digital cursor 6, which can slide on the ruler body 2. The digital cursor 6 includes a vernier 7 and a digital display reading unit 8 connected thereto. The...

Abstract

The invention provides an optical vernier which comprises a base and a vernier body vertically arranged at one end of the base, wherein the bottom of the base just below the vernier body is provided with a fixed bolt, two adjusting screws penetrate through the base, the base is further provided with a bubble water level, the vernier body is provided with a digital vernier in a covering way, and the digital vernier is connected with an optical target. The method for detecting the planeness and the gradient comprises the following steps of: selecting a plurality of detecting points, and recording the coordinate value of each detecting point; stably erecting and leveling a balance level, putting the optical vernier on a place to be detected, detecting the height of any one of detecting points, and setting reference height; sequentially detecting the altitude difference values of the other detecting points; and finding out three special detecting points to be defined to be highest points, wherein the plane formed by the three special detecting points is a reference plane, computing the distance between each detecting point and the reference plane, and taking a maximum value as the planeness of the plane to be detected. The optical vernier provided by the invention is high in detection precision, convenient and quick to detect, convenient to operate at an engineering site, objective and exact in the evaluation data of the planeness, and less influenced by human factors.

Description

technical field [0001] The invention relates to the field of flatness and inclination detection, in particular to an optical scale and a method for detecting flatness and inclination using the same. Background technique [0002] In various test benches, the platform base is the basis for installing precision mechanical parts, and is often welded together with the steel skeleton of the civil structure. In order to ensure the installation accuracy and stability of mechanical parts, the mounting surface and the surface It should be able to be tightly joined, so there are certain requirements for the flatness and levelness of the surface of the platform base. Since the platform foundation is installed during civil construction, the flatness and inclination detection of the platform base surface must be carried out on site, and the necessary plane grinding can only be done manually on site. [0003] Usually, the flatness of the platform base is tested using the flat plate detect...
