Embodiment Construction

[0023] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the scope of protection of the present invention is not limited to the following embodiments.

[0024] Such as figure 1 As shown, this embodiment includes: a mobile measuring cup 1 , a reference measuring cup 2 , a conduit 3 , a buoy 4 , a caliper 5 , and a connecting rod 6 . Both the mobile measuring cup 1 and the reference measuring cup 2 have transparent openings. The moving measuring cup 1 and the reference measuring cup 2 are connected through the conduit 3, the buoy 4 floats on the liquid surface of the moving measuring cup 1, the buoy 4 is connected with the caliper 5 through the connecting rod 6, and the scale on the caliper 5 is connected with the moving measuring cup 1. Vernier calipers are formed between the scales for measurement.

[0025] Such as Figure 2-3 As shown, the mobile measuring cup 1 is provided with grooves away from t...

Abstract

The invention relates to a device and a method for measuring the planeness of guide rails of a large-size revolving platform in the technical field of measurement. The device comprises movable measuring cups, reference measuring cups, conduits, buoys, calipers and connecting rods, wherein a liquid is filled in the measuring cups; the movable measuring cups and the reference measuring cups in various places are connected with each other through the conduits; the buoys are floated on the liquid level of the movable measuring cups; the calipers are connected with the buoys through the connecting rods; and scales on the calipers and scales of the measuring cups form vernier calipers. The movable measuring cups are placed in specified positions on the circumference of the revolving platform, and the planeness of the guide rails which are arranged on adjusting shims is guaranteed by comparison of the measured value of the 'vernier calipers' in the various places and adjustment of the height of the adjusting shims on the specified positions; and the measurement precision of the planeness reaches 0.02 millimeter and is improved by a magnitude order. The invention is suitable for measuring the planeness of the large platform and has the advantages of strong universality, low price, high measurement precision and easy realization.

Description

technical field [0001] The invention relates to a measuring device for measuring flatness in the technical field, in particular to a measuring device and a measuring method for the flatness of a guide rail of a large-size rotary platform. Background technique [0002] In the manufacturing process of large-scale equipment such as modern ships, many large-scale equipment need to be installed on a large-size rotary platform with high flatness requirements, so the rotary platform is the reference plane for the whole machine, component assembly, alignment or welding. The guide rail is installed on the rotary platform, and its flatness directly affects the loading of the rollers in contact with the guide rail. In order to ensure that the rollers are evenly loaded, it is necessary to ensure that the flatness of the guide rail of the large-size rotary platform is less than 0.5mm. In the prior art, the large-size rotary plane refers to its diameter > 10000mm. [0003] At present,...
