Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding tooling technology, and in particular to a welding diagonal brace tooling for columns. Background Technology
[0002] The column welding diagonal brace fixture is mainly used to support and fix the column in order to maintain the stability of the structure during the welding process. With the development of welding technology and the increasing demand for automation, this fixture is designed to improve welding accuracy and efficiency and reduce workpiece deformation. Traditional support methods often result in unstable welding quality due to insecure fixing and inconvenient adjustment. Therefore, this special fixture was developed to achieve precise positioning and stable support during the welding process.
[0003] However, in actual use, the following shortcomings still exist. For example, the existing welding bracing fixture for columns cannot adapt to the bracing and positioning of columns of different diameters, and cannot ensure the stability of the columns during welding. The relative positional deviation between the bracing and the column can lead to uneven welds, inconsistent weld leg heights, and even defects such as incomplete fusion and porosity. When changing columns or bracing of different diameters, the positioning and clamping mechanism of the fixture must be manually adjusted, which increases non-value-added time. If the clamping is unstable during the welding process, the parts may slip or shift, posing a safety hazard. Using unsuitable fixtures to forcibly fix parts of different diameters may cause scratches and dents on the surface of the columns or bracing.
[0004] Therefore, this utility model proposes a column welding diagonal brace tooling to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tooling for welding diagonal braces to columns.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a column welding diagonal brace fixture, including a support frame, and further comprising:
[0007] The diagonal brace adjustment assembly includes a hydraulic push rod rotatably connected to the support frame near the top side. The output end of the hydraulic push rod is rotatably connected to a first rotating rod. One end of the first rotating rod is rotatably connected to the support frame, and the other end of the first rotating rod is rotatably connected to a diagonal brace plate. A second rotating rod is rotatably connected to the support frame near the bottom of the first rotating rod, and the other end of the second rotating rod is rotatably connected to the diagonal brace plate.
[0008] A clamping and positioning assembly includes a support base connected to a brace plate, a drive motor mounted on the support base, a bidirectional lead screw connected to the output end of the drive motor, a moving block threaded onto the bidirectional lead screw, a rotating block mounted on the moving block, and a clamping plate rotatably connected to the rotating block.
[0009] Furthermore, a reinforcing plate is connected to the support frame on the side near the bottom.
[0010] The beneficial effects of adopting the above-mentioned further solution are: the reinforcing plate near the bottom of the support frame suppresses the deformation of the bottom of the support frame. Utilizing the principle of triangular stability, the reinforcing plate and the support frame form a stable structure, enhancing the overall rigidity of the tooling and ensuring that the positioning accuracy of the column and diagonal brace can still be maintained under heavy load conditions.
[0011] Furthermore, a limiting groove is provided on the movable block, and the rotating block is rotatably connected to the support base.
[0012] The beneficial effects of adopting the above-mentioned further solution are: the limiting groove on the moving block cooperates with the rotating block and the limiting block, the limiting groove restricts the moving direction of the limiting block, and when the bidirectional lead screw rotates, the limiting groove constrains the rotating block through the limiting block, ensuring the accuracy of clamping and positioning.
[0013] Furthermore, a limiting block is connected to the side of the rotating block near the limiting groove, and the limiting block is slidably connected within the limiting groove.
[0014] The beneficial effect of adopting the above-mentioned further solution is that the rotating block is connected to the limiting groove of the moving block through the limiting block. When the moving block is driven to move by the bidirectional screw, the limiting block slides in the limiting groove, causing the rotating block to rotate in the support seat.
[0015] Furthermore, the clamp is slidably connected to the support base.
[0016] The beneficial effects of adopting the above-mentioned further solution are: the clamping plate is slidably connected to the support base, and under the drive of the moving block, it slides along the groove of the support base, moving closer to or away from the column, ensuring that the clamping plate moves smoothly, accurately applying clamping force to the column, ensuring the stability of the column, and improving the welding quality.
[0017] Furthermore, the support base has a groove.
[0018] The beneficial effects of adopting the above-mentioned further solution are: the groove provides a precise positioning space for the column. When the column is placed in the groove, the groove restricts its movement in the horizontal direction. At the same time, it works together with the clamping force of the clamping plate to firmly fix the column and ensure that the column will not shift during welding.
[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0020] In this invention, in the diagonal brace adjustment assembly, when the hydraulic push rod is working, its output end extends and retracts, driving the first rotating rod to rotate around the support frame. Because the second rotating rod is rotatably connected to the diagonal brace plate and the support frame, the rotation of the first rotating rod causes the diagonal brace plate to adjust within a certain angle range to adapt to different diagonal brace welding angle requirements. In the clamping and positioning assembly, after the drive motor starts, it drives the bidirectional lead screw to rotate. Because the bidirectional lead screw is threadedly connected to the moving block, the two moving blocks move towards or in opposite directions on the bidirectional lead screw. The moving blocks drive the clamping plate to move through the rotating block. When the column is placed between the clamping plates, the clamping plates can clamp and position it, realizing the diagonal brace and positioning clamping that adapts to columns of different diameters, ensuring that the column remains stable during welding.

[0030] 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.
[0031] like Figure 1 - Figure 5 As shown, this embodiment provides a technical solution: a column welding diagonal brace fixture, including a support frame 1, and further including:
[0032] The diagonal brace adjustment assembly 2 includes a hydraulic push rod 21 rotatably connected to the support frame 1 near the top side. The output end of the hydraulic push rod 21 is rotatably connected to a first rotating rod 22. One end of the first rotating rod 22 is rotatably connected to the support frame 1, and the other end of the first rotating rod 22 is rotatably connected to a diagonal brace plate 23. A second rotating rod 24 is rotatably connected to the support frame 1 near the bottom of the first rotating rod 22, and the other end of the second rotating rod 24 is rotatably connected to the diagonal brace plate 23.
[0033] The clamping and positioning assembly 3 includes a support base 31 connected to the diagonal brace plate 23. A drive motor 32 is mounted on the support base 31. A bidirectional lead screw 33 is connected to the output end of the drive motor 32. A moving block 34 is threaded onto the bidirectional lead screw 33. A rotating block 36 is mounted on the moving block 34. A clamping plate 38 is rotatably connected to the rotating block 36. In the diagonal brace adjustment assembly 2, when the hydraulic push rod 21 is working, its output end extends and retracts, driving the first rotating rod 22 to rotate around the support frame 1. Because the second rotating rod 24 is rotatably connected to the diagonal brace plate 23 and the support frame 1, the first rotating rod... The rotation of the moving rod 22 causes the diagonal brace 23 to adjust within a certain angle range to adapt to different welding angle requirements of the diagonal brace. In the clamping and positioning assembly 3, after the drive motor 32 is started, it drives the bidirectional lead screw 33 to rotate. Since the bidirectional lead screw 33 is threadedly connected to the moving block 34, the two moving blocks 34 move towards or away from each other on the bidirectional lead screw 33. The moving block 34 drives the clamping plate 38 to move through the rotating block 36. When the column is placed between the clamping plates 38, the clamping plates 38 can clamp and position it, realizing the diagonal brace and positioning clamping that adapts to columns of different diameters, ensuring that the column remains stable during welding.
[0034] The above solutions also have the problem of not being able to guarantee the accuracy of clamping and positioning when clamping and positioning the column, such as... Figure 1 - Figure 3As shown: A reinforcing plate 25 is connected to the side of the support frame 1 near the bottom. The reinforcing plate 25 near the bottom of the support frame 1 suppresses the deformation of the bottom of the support frame 1. Utilizing the principle of triangular stability, the reinforcing plate 25 and the support frame 1 form a stable structure, which enhances the overall rigidity of the tooling and ensures that the positioning accuracy of the column and the diagonal brace can still be maintained under heavy load conditions.
[0035] like Figure 1 as well as Figure 4 - Figure 5 As shown, a limiting groove 35 is provided on the movable block 34, and the rotating block 36 is rotatably connected to the support base 31. The limiting groove 35 on the movable block 34 cooperates with the rotating block 36 and the limiting block 37. The limiting groove 35 restricts the movement direction of the limiting block 37. When the bidirectional lead screw 33 rotates, the limiting groove 35 constrains the rotating block 36 through the limiting block 37 to ensure the accuracy of clamping and positioning. The side of the rotating block 36 closest to the limiting groove 35 is connected to the limiting block 37, which is slidably connected in the limiting groove 35. The rotating block 36 is connected to the limiting groove 35 of the movable block 34 through the limiting block 37. When the movable block 34 is driven to move by the bidirectional lead screw 33, the limiting block 37... The limiting groove 35 slides within the column, causing the rotating block 36 to rotate within the support base 31. The clamping plate 38 is slidably connected to the support base 31. Driven by the moving block 34, the clamping plate 38 slides along the groove of the support base 31, moving closer to or away from the column, ensuring that the clamping plate 38 moves smoothly and applies a precise clamping force to the column, ensuring the stability of the column and improving the welding quality. The support base 31 has a groove 39, which provides a precise positioning space for the column. When the column is placed in the groove 39, the groove 39 restricts its movement in the horizontal direction. At the same time, it works together with the clamping force of the clamping plate 38 to firmly fix the column, ensuring that the column will not shift during welding.
[0036] like Figure 1 - Figure 5 As shown:
[0037] Firstly, regarding the adjustment of the diagonal brace, the hydraulic push rod 21 is activated, and its output end retracts. This retraction causes the first rotating rod 22 to rotate around the support frame 1. Since the second rotating rod 24 is rotatably connected to the diagonal brace plate 23 and the support frame 1 respectively, when the first rotating rod 22 rotates, the second rotating rod 24 provides support and linkage, enabling the diagonal brace plate 23 to be flexibly adjusted within a certain angle range to meet the requirements of different diagonal brace welding angles. During the column positioning and clamping process, after the drive motor 32 is started, it drives the bidirectional lead screw 33 to rotate. Based on the threaded connection characteristics between the bidirectional lead screw 33 and the moving block 34, the two moving blocks 34 can move towards or in opposite directions on the bidirectional lead screw 33. The limiting groove 3 on the moving block 34... 5 works in conjunction with the rotating block 36 and the limiting block 37. When the moving block 34 moves, the limiting block 37 slides in the limiting groove 35, causing the rotating block 36 to rotate in the support base 31. In turn, the rotating block 36 drives the clamping plate 38 to move. The clamping plate 38 is slidably connected to the support base 31, and can smoothly approach or move away from the column. At this time, the clamping plate 38 clamps the column in the groove 39, realizing precise positioning and clamping of columns of different diameters, ensuring the stability of the column during welding. In addition, the reinforcing plate 25 at the bottom of the support frame 1 forms a stable triangular structure with the support frame 1, effectively suppressing the deformation of the bottom of the support frame 1, enhancing the overall rigidity of the tooling, ensuring that the positioning accuracy of the column and the diagonal brace can still be maintained under heavy load conditions, and improving the welding quality.
[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
