Description

Technical Field

[0001] This utility model relates to the field of column welding technology, specifically to a welding fixture for support columns. Background Technology

[0002] In the welding of square tubes, H-beams and other profiles to the base, the square tubes or H-beams are usually horizontally supported by a support frame before being precisely welded to the base. In this process, the base, as a key load-bearing component, directly determines the overall structural stability of the support column by the accuracy of its relative position to the profile. Therefore, the support stability and positioning accuracy of the base are required to be high.

[0003] However, in existing welding operations, the support frames used for horizontally supporting square tubes and H-beams are mostly fixed structures, making it difficult to adjust their positions according to different dimensions such as the side length of the square tube and the flange width of the H-beam. This makes it difficult to quickly calibrate the mating position between the profile and the base. At the same time, the base lacks a dedicated support structure adapted to the support frame and relies only on simple pads or ground support. Under the action of welding stress and the workpiece's own weight, it is prone to displacement or tilting. This not only increases the difficulty of manual alignment but also causes fluctuations in welding quality due to inaccurate positioning, seriously affecting the installation accuracy and performance of the subsequent support columns. Utility Model Content

[0004] The purpose of this utility model is to provide a welding fixture for support columns to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A welding fixture for a support column includes a support frame, a column, and a base plate. Two support frames are symmetrically distributed front to back. The column is placed on top of the two columns, and the base plate is placed on the front side of the column. An adjustable support assembly is provided on the outer side of the front support frame. The adjustable support assembly includes a movable plate and limiting blocks. The movable plate is slidably connected to the front side of the front support frame, and its top is in contact with the bottom of the base plate. Two limiting blocks are slidably installed on the outer side of the movable plate, and their inner sides are in contact with the outer side of the base plate.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, both of the limiting blocks are L-shaped, and rubber pads are fixed to the rear side of the vertical section of each of the two limiting blocks. The rear side of the two rubber pads is in contact with the front side of the base plate, and the opposite sides of the horizontal sections of the two limiting blocks are in contact with the left and right sides of the base plate, respectively.

[0009] Furthermore, each of the two limiting blocks has an installation groove inside its horizontal section, and a magnetic block is fixedly installed inside each of the two installation grooves.

[0010] Furthermore, the adjusting support assembly also includes two connecting plates, both of which are fixedly installed on the outside of the front support frame. A guide rod is movably installed inside the left connecting plate, and the bottom of the guide rod is fixed to the top of the movable plate. A lead screw is rotatably installed inside the right connecting plate via a bearing. The bottom of the lead screw penetrates the interior of the movable plate, and a transmission block is threaded to the outside of the lead screw. The top of the transmission block is fixed to the bottom of the movable plate, and a handwheel is fixedly installed on the top of the lead screw.

[0011] Furthermore, there are three adjustable support components, which are evenly distributed on the outer side of the front support frame.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] With the cooperation of guide rods, lead screws, and transmission blocks, the position of the moving plate can be adjusted to better adapt to base plates of different sizes. Furthermore, the position of the base plate is simply restricted by the limiting blocks, making it easy to align the column with the base plate with manual assistance, thus facilitating subsequent welding and ensuring the performance of the support column.

[0020] 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.

[0021] Reference Figures 1-4 As shown, this utility model provides a welding fixture for a support column, including a support frame 1, a column 2, and a base plate 3. There are two support frames 1, which are symmetrically distributed front and back. The column 2 is placed on top of the two columns 2. The base plate 3 is placed on the front side of the column 2. An adjustable support assembly 4 is provided on the outer side of the front support frame 1. The adjustable support assembly 4 includes a movable plate 401 and a limiting block 402. The movable plate 401 is slidably connected to the front side of the front support frame 1. The top of the movable plate 401 is in contact with the bottom of the base plate 3. There are two limiting blocks 402, which are slidably installed on the outer side of the movable plate 401 respectively. The inner side of the two limiting blocks 402 is in contact with the outer side of the base plate 3.

[0022] The rear side of the base plate 3 is attached to the front side of the front support frame 1, and the position of the base plate 3 is adjusted by the action of the moving plate 401 so that it is aligned with the center of the column 2. The base plate 3 is initially restricted by the two limiting blocks 402 to facilitate subsequent welding.

[0023] Both limiting blocks 402 are L-shaped, and rubber pads 403 are fixed to the rear side of the vertical section of both limiting blocks 402. The rear side of the two rubber pads 403 is attached to the front side of the base plate 3, and the opposite sides of the horizontal sections of the two limiting blocks 402 are attached to the left and right sides of the base plate 3 respectively.

[0024] This configuration increases the friction between the base plate 3 and the limiting block 402 by using the rubber pad 403, thereby improving the limiting effect of the limiting block 402 on the base plate 3 and improving the accuracy of subsequent welding processes.

[0025] The horizontal sections of the two limiting blocks 402 are each provided with a mounting groove 404, and a magnetic block 405 is fixedly installed inside each of the two mounting grooves 404.

[0026] With this configuration, the base plate 3 is made of a material that can be magnetically attracted, thereby further enhancing the connection between the limiting block 402 and the base plate 3 under the action of the magnetic block 405, strengthening the limiting effect on the base plate 3, and improving the stability during the welding process.

[0027] The adjusting support assembly 4 also includes two connecting plates 406, both of which are fixedly installed on the outside of the front support frame 1. A guide rod 407 is movably installed inside the left connecting plate 406, and the bottom of the guide rod 407 is fixed to the top of the moving plate 401. A lead screw 408 is rotatably installed inside the right connecting plate 406 via a bearing. The bottom of the lead screw 408 penetrates the inside of the moving plate 401, and a transmission block 409 is threadedly connected to the outside of the lead screw 408. The top of the transmission block 409 is fixed to the bottom of the moving plate 401, and a handwheel 410 is fixedly installed on the top of the lead screw 408.

[0028] With this configuration, the screw 408 is rotated by the handwheel 410, and the rotational degree of freedom is eliminated under the action of the guide rod 407 and the connecting plate 406 on the left side. This allows the transmission block 409 to drive the moving plate 401 to move linearly, achieving stable lifting and lowering, and completing the adjustment of the position of the moving plate 401. It also makes it easy to ensure the position of the moving plate 401 after adjustment.

[0029] Among them, there are three adjustment support components 4, which are evenly distributed on the outside of the front support frame 1.

[0030] This setup allows for multiple columns 2 to be installed on the support frame 1, enabling multiple workers to perform welding operations, or multiple columns 2 to be installed on two support frames 1, facilitating individual welding by operators.
