Embodiment Construction

[0063] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0064] In order to understand this solution more clearly, here is a brief description of the structure of the previous struts.

[0065] figure 1 is a front view of a front strut, such as figure 1 As shown, the front strut 100 includes a middle strut 110, an I-beam 120 and a flange 130, and the middle strut 110 and the flange 130 are respectively located at two ends of the I-beam 120, figure 2 is a top view of the front strut 100, as figure 2 As shown, the I-beam 120 and the flange 130 are all along the central plane ZX of the front strut 100 0 Symmetrical setting. Such as figure 1 and figure 2 As shown, the bottom surface of the central strut 110, the central plane ZX 0 Two by two are perpendicular to the sides connected with...

Abstract

The invention discloses a method for detecting the machining allowance of a flange surface, and relates to the technical field of processing measurement. Both ends of the I-beam, the I-beam and the flange are arranged symmetrically along the central plane of the front strut, and the flange surface is the surface of the flange parallel to the length direction of the I-beam. In the flange surface machining allowance detection method in the embodiment of the present invention, by first determining any point on the flange surface as a reference point, any point on the flange surface except the reference point as a reference point, and then according to the reference point and the center Machining allowance in the direction of distance from the plane and the reference point and the center plane ZX 0 The machining allowance in the distance direction determines the machining allowance of the flange surface, thus getting rid of the dependence on the marking platform, and then directly passing through the center plane ZX on the front strut without passing through the marking platform 0 To determine the machining allowance of the flange surface, improve the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of machining measurement, in particular to a method for detecting a machining allowance of a flange surface. Background technique [0002] Slewing bearing cranes are the most commonly used offshore lifting equipment among platform cranes. Wire rope luffing truss jib crane is a main type of slewing bearing crane, which consists of four major structures: base column, turntable, A-frame and jib. The A-frame is a supporting structure composed of front struts, rear tie rods, hinged beams, and pin shaft parts. [0003] figure 1 is a front view of a front strut, such as figure 1 As shown, the front strut 100 includes a middle strut 110 , an I-beam 120 and a flange 130 , and the middle strut 110 and the flange 130 are respectively located at two ends of the I-beam 120 . figure 2 is a top view of the front strut 100, as figure 2 As shown, the I-beam 120 and the flange 130 are all along the central plane ZX of ...
