Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure processing equipment, specifically a large H-frame welding fixture. Background Technology

[0002] In the field of large steel structure manufacturing, welding of H-beams is a common production process. Traditionally, in large H-beam welding operations, due to the large size and heavy weight of the components, operators typically need to frequently rotate the components using hoisting equipment to adjust their welding positions. This method has significant technical drawbacks: First, repeatedly adjusting the component angles manually is not only labor-intensive and inefficient, but also poses safety hazards; second, manual positioning makes it difficult to ensure precise alignment between components, easily leading to uneven welds and welding deformation; third, existing welding fixtures mostly use fixed support structures, lacking multi-angle adjustment capabilities, making it difficult to meet the welding needs of complex spatial positions.

[0003] To address the aforementioned issues, there is an urgent need for a welding fixture that can freely adjust the orientation of welded components from multiple angles and achieve precise positioning with small-distance adjustments between components. Utility Model Content

[0004] The purpose of this invention is to provide a large H-frame welding fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large H-frame welding fixture, comprising a circular plate, a first rotating shaft at the lower part of the circular plate, the first rotating shaft being installed in a support, and multiple legs on the support; two support rods at the upper part of the circular plate, a base plate at the top of the support rods, a first support plate and a second support plate on the base plate, the first support plate and the second support plate being connected to the base plate via a second rotating shaft, two push rods on the base plate, and a slot on the upper surface of the base plate; a third rotating shaft at the upper part of the first support plate and the second support plate, a fixing plate fixed on the third rotating shaft, and a circular tube installed between the first support plate and the second support plate, with fixing buckles at both ends of the circular tube, capable of connecting to the large H-frame to be processed.

[0006] In a preferred embodiment of this utility model, the first rotating shaft is connected to a motor and can be controlled by a controller to rotate or stop in the support.

[0007] In a preferred embodiment of this utility model, the two support rods are symmetrically arranged on the circular plate.

[0008] In a preferred embodiment of this utility model, the direction of the slot is perpendicular to the first support plate and the second support plate.

[0009] In a preferred embodiment of this invention, the push rod is connected to a motor and can be controlled by a controller to move along the slot.

[0010] In a preferred embodiment of this utility model, the inner surface of the fixing plate is stepped.

[0011] In a preferred embodiment of this invention, the third rotating shaft is connected to a motor and can be rotated by a controller.

[0012] The large H-frame welding fixture proposed in this utility model has the following beneficial effects:

[0013] The rotational design of the first rotating shaft and the circular tube assists welding workers in flipping H-frame components during the welding process, reducing the workload of manually flipping H-frame components. Through motor drive and controller coordination, the workload of welding H-frame components is further reduced, while also facilitating fine-tuning of components in mid-air, increasing the precision of the welding.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 One specific embodiment of this utility model is as follows:

[0020] A large H-frame welding fixture includes a circular plate 01, with a first rotating shaft 02 located at the lower part of the circular plate 01. The first rotating shaft 02 is mounted in a support 03, and the support 03 has multiple support legs 04. The first rotating shaft 02 is connected to a motor and can be controlled to rotate or stop within the support 03 by a controller.

[0021] Two support rods 05 are symmetrically positioned on the upper part of the circular plate 01. A base plate 06 is located on the top of the support rods 05. A first support plate 07 and a second support plate 08 are mounted on the base plate 06. The first support plate 07 and the second support plate 08 are connected to the base plate 06 via a second rotating shaft 09. Two push rods 12 are located on the base plate 06, respectively, on the outer side of the first support plate 07 and the second support plate 08. A slot 13 is provided on the upper surface of the base plate 06 perpendicular to the first support plate 07 and the second support plate 08. The push rods 12 are connected to a motor and can be controlled by a controller to move along the slot 13. By controlling the position of the push rods 12 in the slot 13, the angle between the first support plate 07 and the second support plate 08 can be adjusted. A third rotating shaft 11 is located above the first support plate 07 and the second support plate 08. A fixing plate 10 is fixed on the third rotating shaft 11. The inner surface of the fixing plate 10 is stepped and used to fix the circular tube 14. The third rotating shaft 11 is connected to a motor and can be rotated by a controller, thereby adjusting the angle between the fixed plate 10 and the first support plate 07 and the second support plate 08. A round tube 14 is installed between the first support plate 07 and the second support plate 08. The round tube 14 has fixing buckles 15 at both ends, which can be connected to the large H-frame to be processed.

[0022] In this embodiment, the circular tube 14 is installed between the first support plate 07 and the second support plate 08. The third rotating shaft 11 is rotated to make the fixing plate 10 fit tightly against the circular tube 14 to prevent it from rotating. The H-frame components to be welded are then installed on the fixing clips 15 at both ends of the circular tube 14. After installation, the third rotating shaft 11 is rotated to make the fixing plate 10 leave the circular tube 14. The circular tube 14 is manually rotated and adjusted to make the H-frame components at an angle that is easy to weld. The circular tube 14 is then fixed again by the fixing plate 10. Adjusting the first rotating shaft 02 causes the circular plate 01 to rotate the entire upper structure, which can assist in the positioning and docking of the H-frame components. This tooling significantly reduces the manual work of flipping and adjusting components during the welding of large H-frames, and replaces some of the work of adjusting the position of large components with mechanical control, making it easier to adjust the weld size between components, reducing workload and improving welding precision.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
