Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding fixtures for steel structure components, specifically to high-precision positioning welding fixtures for steel structure components. Background Technology
[0002] With a multi-component precision transmission and positioning mechanism as its core, this invention relates to the field of welding fixtures for steel structure components, and solves the problems of low component positioning accuracy and insufficient welding stability in traditional welding.
[0003] A search revealed existing technology (application number: CN206883105U), which describes "a positioning welding fixture for I-beams". This utility model's left side plate mounting device includes a left worktable, a left transverse slide, a left vertical plate, a left screw, a left adjusting plate, a left adjusting bolt, a left spot welding head, and a left longitudinal slide. The left transverse slide is mounted on the left worktable. A set of screw through holes is opened on the left vertical plate. The left adjusting plate is mounted on one end of the left screw, and the left screw is located within one of the screw through holes in the set of screw through holes on the left vertical plate.
[0004] However, while existing technologies achieve automated welding, eliminate complex positioning processes, and are convenient and fast, and can produce various types of I-beams, they still have some shortcomings: existing technologies have low positioning accuracy when welding different types of I-beams, and the stability after welding is insufficient. This invention achieves higher positioning accuracy by clamping on the same horizontal plane and fine-tuning the left and right steel pipes. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-precision positioning and welding fixture for steel structure components.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision positioning welding fixture for steel structure components, comprising: a base with support plates on both sides; a column arranged on the base; a lifting assembly including a support plate slidably connected to the column, and a threaded rod rotatably connected to the column, wherein the threaded rod is threadedly connected to the support plate; a clamping assembly including a clamping plate slidably connected to the support plate; a telescopic assembly including a sliding plate slidably connected to the clamping plate, wherein protrusions are provided on both sides of the sliding plate; and a fixing assembly including a placement groove arranged on the support plate on the base, and a fixing block fixedly connected to the placement groove.
[0007] As a further description of the above technical solution:
[0008] The lifting assembly includes: a worm gear rotatably connected to the column; and a worm wheel arranged on the threaded rod and meshing with the worm gear.

[0011] As a further description of the above technical solution:
[0012] The telescopic assembly includes: a threaded rod three, threadedly connected to the clamping plate; and a pressing block, slidably connected to the clamping plate and rotatably connected to the threaded rod three, for pressing the protrusion on the sliding plate.
[0013] As a further description of the above technical solution:
[0014] The fixing component includes: a threaded hole formed on a support plate on the base.
[0015] As a further description of the above technical solution:
[0016] The bottom of the second support plate is provided with guide posts for guidance.
[0017] As a further description of the above technical solution:
[0018] The fixing block has through holes for fine-tuning.
[0019] This utility model has the following beneficial effects:
[0020] The core technology of this tooling achieves high-precision positioning and welding through the collaboration of multiple components. The lifting component uses worm gear and threaded rod transmission to precisely adjust the height of the second support plate; the clamping component relies on the threaded rod of the symmetrical thread to make the clamping plates slide towards each other to clamp the components; the threaded rod of the telescopic component drives the pressure block to fix the sliding plate and ensure the components are fixed.
[0021] The ultimate goal is to achieve precise positioning of steel structure components during the welding process, reduce errors caused by manual adjustments, and enable tooling fixation and component fine-tuning through threaded holes, thereby improving welding accuracy and stability, and enhancing welding efficiency and quality.

[0028] 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.
[0029] Example 1
[0030] like Figures 1 to 4 As shown, the high-precision positioning and welding fixture for steel structure components provided in this embodiment includes: a base 1 with support plates on both sides; a column 2 arranged on the base 1; a lifting assembly including a support plate 3 slidably connected to the column 2, and a threaded rod 6 rotatably connected to the column 2, and the threaded rod 6 being threadedly connected to the support plate 3; a clamping assembly including a clamping plate 9 slidably connected to the support plate 3; a telescopic assembly including a sliding plate 10 slidably connected to the clamping plate 9, and protrusions on both sides of the sliding plate 10; and a fixing assembly including a placement groove 13 arranged on the support plate on the base 1, and a fixing block 14 fixedly connected to the placement groove 13.
[0031] In this embodiment, the horizontal and vertical fixing of the steel pipe is achieved through the connection and cooperation of various components, which facilitates welding.
[0032] Specifically, the lifting assembly includes: a worm gear 4, rotatably connected to the column 2; and a worm wheel 5, arranged on the threaded rod 6 and meshing with the worm gear 4.
[0033] Rotating the worm gear 4 drives the threaded rod 6 to rotate via the worm wheel and worm gear transmission, and drives the support plate 3 to rise and fall along the column 2 via the threaded transmission, increasing the transmission torque and making the rise and fall of the support plate 3 more stable and precise.
[0034] Specifically, the clamping assembly includes: a threaded rod 8, which is rotatably connected to the support plate 3, and the threads on its surface are symmetrically arranged and threadedly connected to the clamping plate 9.
[0035] As a preferred implementation method, rotating the threaded rod 8 allows the two clamping plates 9 to slide towards or away from each other along the column 2 using symmetrical threads, thereby clamping and positioning the steel structure components.
[0036] Example 2
[0037] Specifically, the telescopic assembly includes: a threaded rod 11, which is threadedly connected to the clamping plate 9; and a pressing block 12, which is slidably connected to the clamping plate 9 and rotatably connected to the threaded rod 11, for pressing the protrusion on the sliding plate 10.
[0038] It should be noted that rotating the threaded rod 11 causes the clamping block 12 to slide along the clamping plate 9, clamping the protrusion and fixing the position of the sliding plate 10 to prevent it from sliding.
[0039] Specifically, the fixing component includes: a threaded hole 15, which is formed on a support plate 1 on the base 1.
[0040] As a preferred implementation, the tooling is fixed to the worktable by passing bolts through the threaded hole 15, thereby achieving the fixed installation of the tooling.
[0041] Example 3
[0042] Specifically, the bottom of the support plate 2 3 is provided with a guide post 7 for guidance.
[0043] It should be noted that the direction of movement of the second support plate 3 is guided to improve the stability and guiding accuracy of the movement of the second support plate 3.
[0044] Specifically, the fixing block 14 has a through hole 16 for fine adjustment.
[0045] In use, the user first places the steel pipe on the support plate 2 3 and rotates the worm gear 4 to drive the worm wheel 5 to rotate, which in turn drives the threaded rod 1 6 to rotate. At this time, the support plate 2 3 slides on the column 2. After adjusting to a suitable height, the user places the vertical steel pipe on both sides of the horizontal steel pipe and determines the approximate position through the fixing block 14 and the threaded hole 15. Then, fine-tuning is done through the through hole 16. After preparation, the user first pulls the sliding plate 10 to the appropriate position on both sides, and then rotates the threaded rod 3 11 to drive the clamping block 12 to move downward, thereby restricting the movement of the sliding plate 10. At this time, rotating the threaded rod 2 8 drives the clamping plate 9 to move in opposite directions, clamping the horizontal steel pipe and the vertical steel pipe at the same time.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
