Problems solved by technology

This method is inaccurate and wrong, because the main nodes of the hull generally have a certain angle. If the above method is used, no matter what angle is used, the distance requirement may be met, and there is no measurement basis for the node angles

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0022] see figure 1 , figure 1 It is a structural schematic diagram of the main node tolerance inspection template of the present invention. As shown in the figure, a tolerance inspection template for the main node of the hull includes the first angle side 1, the second angle side 2 and the hypotenuse 3, and the gap between the two angle sides There is a certain angle, and three scale lines are arranged above the first angle side, the middle scale line is the theoretical scale line, and the scale lines on both sides are the range scale lines allowed by the tolerance inspection standard. There is a hole 5 in the center of the template.

[0023] When manufacturing the hull main node tolerance inspection template of the present invention, the sideline name 6 should be clearl...

Abstract

The invention discloses a tolerance test template for a master node of a ship hull and a detection method thereof. The tolerance test template is formed by surrounding a first angle side, a second angle side and a hypotenuse; a certain angle is formed between the first angle side and the second angle side; three graduation marks are arranged above the first angle side; the middle graduation mark is a theoretical graduation mark; and the graduation marks at the two sides are range graduation marks allowable to the tolerance test standards. The tolerance test template for the master node of the ship hull and the detection method thereof have the advantages that: the measurement of the node of the ship hull is facilitated, a basis is provided for angle measurement, and the tolerance test template is simple in structure and convenient in carrying.

Description

technical field [0001] The invention relates to the technical field of assembly tolerance inspection of ship main nodes, mainly belongs to the assembly operation of the main hull nodes generated during the loading process of the general group, and meets the construction tolerance inspection of various nodes by changing the angle of the template. Background technique [0002] During the loading process of the general ship group, the assembly of the main nodes of the hull is relatively difficult. One of the reasons is that the main nodes of the hull generally have a specific angle, and there is no tooling or inspection equipment for auxiliary assembly operations. It is difficult for construction personnel to ensure that the nodes meet the construction tolerance requirements The second reason is that the welding requirements of the main nodes of the hull are generally high, and a part of the assembly gap is required and the requirements for the welding groove are relatively high...
