Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a welding fixture for an annular frame. Background Technology

[0002] Welded components are assemblies formed by connecting multiple metal parts through welding processes. They are widely used in fields such as machinery manufacturing and construction engineering. There are many types of welded components, such as welded frame structures, which can be used in different application areas and have different shapes and structures, such as ring-shaped frame structures. During the welding process, appropriate fixtures are required to fix the main body to complete the welding in an accurate position. For ring-shaped frames, there are currently no corresponding fixtures to complete the clamping, which affects the accuracy and stability of the welding. Utility Model Content

[0003] The purpose of this utility model is to provide a welding fixture for annular frames to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a welding fixture for a ring-shaped frame, used to fix the ring-shaped frame, comprising:

[0005] Base plate;

[0008] Multiple clamping units are set on the base plate. The clamping units are arranged around the outside of the first positioning plate and the second positioning plate. Each clamping unit includes a clamp and a clamping body. The clamp can drive the clamping body to rotate and restrict the annular frame to the first positioning plate and the second positioning plate.

[0009] Furthermore, there is a gap between the second positioning plate and the first positioning plate, the gap allowing a portion of the annular frame to be inserted, the annular frame being fitted outside the first positioning area and partially located above the first positioning area.

[0010] Furthermore, when the clamping body contacts the annular frame, it is located inside the second positioning plate and above the first positioning plate.

[0011] Furthermore, the clamping body includes a mounting plate and a limiting plate. The mounting plate is connected to the clamp, and the limiting plate is in contact with the annular frame. Slots are provided on both sides of the mounting plate, and an insertion block is provided at one end of the limiting plate. The insertion block is inserted into the slot.

[0012] Furthermore, the limiting plate includes an upper plate and a side plate, with a notch formed between the upper plate and the side plate for the annular frame to pass through. The upper plate contacts the upper end of the annular frame, and the side plate contacts the inner side of the annular frame. The insert block is disposed at the upper end of the upper plate.

[0013] Furthermore, the two limiting plates are arranged in parallel and symmetrically.

[0014] Furthermore, the two limiting plates are symmetrically arranged and form a 90° included angle.

[0015] This utility model has the following beneficial effects:

[0016] This invention enables rapid positioning, clamping, and fixing of ring-shaped, especially rectangular, frames, preventing the frames from shifting during welding and ensuring the stability and accuracy of the welding process. Attached Figure Description

[0022] 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.

[0023] Example 1

[0024] like Figures 1-4As shown, the welding fixture for the annular frame provided in this embodiment is used to fix the annular frame 1. The annular frame 1 has a closed rectangular structure and has an outer frame 101 and an inner edge 102 that needs to be welded and fixed inside the outer frame 101.

[0025] Specifically, the welding fixture mainly consists of a base plate 10, multiple first positioning plates 20 arranged side by side on the base plate 10, multiple second positioning plates 30 arranged on both sides of the first positioning plates 20, and multiple clamping units 40 arranged on the base plate 10.

[0026] In this configuration, multiple first positioning plates 20 form a first positioning area, and at least two adjacent first positioning plates 20 are spaced apart, which can reduce the number of first positioning plates 20 used.

[0027] Furthermore, the second positioning plate 30 is higher than the first positioning plate 20, and there is a gap between the second positioning plate 30 and the first positioning plate 20. The gap allows a portion of the annular frame 1 to be inserted. The annular frame 1 is fitted outside the first positioning area and partially located above the first positioning area. That is, the outer frame 101 is fitted outside the first positioning area and inserted into the gap between the second positioning plate 30 and the first positioning plate 20, thus completing the quick positioning and installation of the outer frame 101. The inner edge 102 is placed above the second positioning plate 30 and close to the outer frame 101.

[0028] The clamping unit 40 is arranged around the outside of the first positioning plate 20 and the second positioning plate 30. The clamping unit 40 includes a clamp 41 and a clamping body 42. The clamp 41 can drive the clamping body 42 to rotate and restrict the annular frame 1 on the first positioning plate 20 and the second positioning plate 30.

[0029] Here, when the clamping body 42 contacts the annular frame 1, it is located inside the second positioning plate 30 and above the first positioning plate 20.

[0030] The clamping body 42 includes a mounting plate 421 and a limiting plate 422. The mounting plate 421 is connected to the clamp 41, and the limiting plate 422 is in contact with the annular frame 1. The mounting plate 421 has slots 423 on both sides, and the limiting plate 422 has an insertion block 424 at one end. The insertion block 424 is inserted into the slots 423. The limiting plate 422 includes an upper plate 4221 and a side plate 4222. A notch 4223 is formed between the upper plate 4221 and the side plate 4222 for the annular frame 1 to pass through. That is, the limiting plate 422 is generally L-shaped. The upper plate 4221 is in contact with the upper end of the annular frame 1, and the side plate 4222 is in contact with the inner side of the annular frame 1. The insertion block 424 is located at the upper end of the upper plate 4221, thereby pressing the inner edge 102 against the outer frame 101 to complete the clamping and facilitate subsequent welding and fixing.

[0031] Here, the clamping body 42 located on the long or short side of the outer frame 101 has two limiting plates 422 arranged in parallel and symmetrically, and perpendicular to the corresponding position of the outer frame 101. Here, the mounting plate 421 assembled with the limiting plate 422 has a straight plate structure and is generally in the shape of a straight line.

[0032] Additionally, the clamping body 42 located at the arc-shaped corner position of the outer frame 101 has two limiting plates 422 symmetrically arranged and forming a 90° angle, and the corresponding mounting plate 421 has an arc-shaped structure, which facilitates clamping and fixing at the arc-shaped corner position.

[0033] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
