Embodiment Construction

[0055] The present invention will be further described in conjunction with the accompanying drawings.

[0056] see Figure 1~15 , the present invention designs a precision control process for high-precision boring of hinges on site, including the following steps:

[0057] S1. Control the accuracy of the opening size of the hinge eye plate;

[0058] S2. Control the accuracy of the axis reference line of the hinge eye plate;

[0059] S3, carry out boring processing, and control the precision of boring processing;

[0060] S4. Carry out a boring accuracy test.

[0061] In actual implementation, before performing the above steps, process preparation must first be carried out, that is, to determine the construction drawings and related process technical documents, indicators, parameters, etc., and then prepare relevant machining equipment, such as BB5000 boring machine, FF 250-700 scraper Plane machine, MD150 magnetic drill, etc., and then check the measuring equipment, such as...

Abstract

The invention relates to the technical field of pontoon bridge construction, in particular to a precision control process of hinge on-site high-precision boring. The process comprises the following steps of S1, controlling the precision of the opening size of a hinge eye plate, S2, controlling the precision of the axis reference line of the hinge eye plate, S3, carrying out boring machining and controlling the boring machining precision, and S4, carrying out boring precision inspection. The problems that the installation precision of the hinge eye plate is difficult to control and the boring precision requirement is difficult to meet in the construction of the French pontoon bridge are solved, and meanwhile marking deviation, machining deviation and deformation caused by temperature difference in the machining process, which are likely to occur in the axis line marking process, the boring machining process and the hinge eye plate shaft hole finishing inspection process are eliminated,so that the French pontoon bridge on-site boring process achieves the purposes of high precision, high quality, high efficiency and cost reduction.

Description

technical field [0001] The invention relates to the technical field of pontoon bridge construction, in particular to an on-site precision boring precision control process for hinges. Background technique [0002] In the French pontoon bridge construction project, the hinge is the key and important support point structure of the pontoon bridge connection, and the installation accuracy is difficult to control. The structure of the French pontoon bridge is complex, the plate is thick, the welding workload is heavy, and the welding deformation cannot be controlled to meet the technical process requirements. Therefore, when the hinge eye plate is installed, additional boring allowances need to be drilled on site. Among them, the sections that require on-site boring: such as connecting towers, upper ramps, upper platforms and rockers, their boring accuracy technical requirements require that the inner distance of the hole is +0~+0.06mm, the roughness meets the Ra3.2 standard, and ...
