Embodiment 1

[0043] Such as Figure 1-7 As shown, a non-standard H-shaped steel assembly positioning fixture includes a platform 7, and the upper surface of the platform 7 is sequentially installed with a plurality of clamping assemblies along the set straight line direction, and each clamping assembly includes a first branch oppositely arranged. The seat 1 and the second support 4, the opposite sides of the first support 1 and the second support 4 are positioning surfaces, and the positioning surfaces are perpendicular to the upper surface of the platform 7 .

[0044] The positioning surface is provided with vertical chute 810, the upper end of the chute 810 runs through the upper end surface of the clamping assembly, and each chute 810 is provided with a positioning plate 5, and the extension of the positioning plate 5 and the clamping assembly The direction is vertical, there is a first setting gap between the two positioning plates 5 , and there is a second setting gap between the two ...

Embodiment 2

[0057] Such as Figure 8-12 As shown, this embodiment also provides a non-standard H-shaped steel assembly positioning method, which utilizes the non-standard H-shaped steel assembly positioning fixture, including the following steps,

[0058] Step 1, a row of second supports 4 is fixedly installed on the platform 7, and the positioning surfaces of multiple second supports 4 are on the same plane;

[0059] Step 2, placing the lower wing plate 11 of the H-shaped steel to be assembled on the upper surface of the platform 7, and the side of the lower wing plate 11 is attached to the positioning surface of the second support 4;

[0060] Step 3, fixedly install a row of first supports 1 on the platform 7, so that the positioning surface of the first supports 1 fits with the other side of the lower wing plate 11;

[0061] Step 4, install the positioning plate 5 in the chute 810, and insert one vertical side of the positioning plate into the chute, so that the positioning plate is p...

Abstract

The disclosure relates to a non-standard H-shaped steel assembly positioning fixture and positioning method, including a platform, the upper surface of the platform is sequentially installed with a plurality of clamping components along the set linear direction, and each clamping component includes two oppositely arranged Supports, the side facing the other supports in each support is a positioning surface; the positioning surface is provided with a vertical chute, the upper end of the chute runs through the upper end surface of the clamping assembly, and each chute is provided with There is a positioning plate, which is perpendicular to the extension direction of the clamping assembly; there is a first set gap between the two positioning plates to complete the clamping of the web; between the positioning surfaces of the two supports in the same clamping assembly There is a second set gap between them to complete the clamping of the wings; the distance between the first support and the second support can be adjusted to adapt to wings of different widths. The disclosure can solve the problem of inconvenient welding and positioning of existing large H-shaped steel.

Description

technical field [0001] The disclosure belongs to the technical field of positioning fixtures, and in particular relates to a non-standard H-shaped steel assembly positioning fixture and a positioning method. Background technique [0002] In some large-scale manufacturing equipment, H-shaped steel is often used as the main part of the equipment base. Because of the large volume and weight of the equipment, the structural size of the H-shaped steel used as support is also very large. [0003] For example, the inventor has learned of a steam turbine produced by GE Company in the United States. The main part of the base is all made of American standard large H-shaped steel, with a size of 719.1*267.8*25.4*15.6*21000mm, and splicing is not allowed in the direction of the length of the H-shaped steel. In some cases, it is formed by welding three equal-length steel plates, which belongs to large super-long H-shaped steel. [0004] The inventor believes that when the rolling method...
