Embodiment Construction
[0039] The present invention is described in detail below in conjunction with the embodiment that accompanying drawing provides:
[0040] The working principle of the present invention is to use the numerical control three-dimensional drill to drill the positioning hole 1 on the surface of the steel structure beam body 2, and combine the simple fixture to ensure the position and size of each part by passing the positioning pin 4. The steel structure beam body 2 in this embodiment H-shaped steel is used.
[0041] See 4- Figure 11 , a method for ensuring the riveting and welding dimensions of a steel structure beam body by using a numerically controlled three-dimensional drill, comprising the following steps:
[0042] 1) Identify the position and size of the parts shown in the drawing, and determine the position and size of the positioning hole 1;
[0043] 2) According to the position and size of each positioning hole 1, draw the 2D graphics distributed on the surface of the ...

The invention belongs to the technical field of steel structure beam welding, and specifically relates to a method for ensuing the rivet welding size of a steel structure beam with a computer numerical control (CNC) three-dimensional drill. The method for ensuing the rivet welding size of the steel structure beam with the CNC three-dimensional drill mainly comprises the step 1) of identifying a drawing; the step 2) of drawing a 2D diagram; the step 3) of entering three-dimensional drill validation procedures; the step 4) of drilling locating holes with the three-dimensional drill; the step 5)of fixedly welding part points with a carrier; and the step 6) of performing overall welding. According to the method provided by the invention, the problems that the welding and locating accuracy ofthe steel structure beam is low and the machining is time and labor-consuming in the prior art are solved.
Description
technical field [0001] The invention belongs to the technical field of steel structure beam body welding, and in particular relates to a method for ensuring the riveting welding size of a steel structure beam body by using a numerically controlled three-dimensional drill. Background technique [0002] The steel structure is composed of multiple columns, beams, diagonal braces, connecting plates and other parts, which are connected by high-strength bolts, gaskets, and fastening nuts. The inner cavity of the beam is welded with ribs and sealing plates, so that the beam forms a box Type structure, to achieve the design purpose of wind resistance, earthquake resistance and load bearing. [0003] Take the beam in the steel structure frame as an example, such as figure 1 and figure 2 As shown, with H-shaped steel as the carrier, the connecting plate of the reinforced beam, the connecting plate of the diagonal brace and the connecting beam are welded to the H-shaped steel accord...
