Description

Technical Field

[0001] This utility model belongs to the field of welding processing technology, specifically relating to a steel structure welding positioning fixture. Background Technology

[0002] Steel structures are widely used in the construction industry. Different structural frames can be made by welding steel structures together for different scenarios. The most commonly used are round steel pipes and square steel pipes.

[0003] Publication No. CN221185304U, Publication Date 20240621, discloses a positioning fixture for welding steel structures, including a positioning platform and supporting legs. The top of the positioning platform is provided with a positioning hole, the inside of the positioning hole is provided with a positioning bolt, and the outside of the positioning bolt is provided with a pressure plate.

[0004] In the prior art, including the aforementioned patent, the positioning bolt is turned by screwing in the threaded engagement with the positioning hole, which can press the pressure plate down and fix the steel structure component by protruding the pressure plate. This not only requires the staff to perform the positioning themselves, but also requires the staff to repeatedly turn the positioning bolt to fix and disassemble the steel structure. The operation is cumbersome and inefficient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a steel structure welding positioning fixture.

[0006] The technical solution adopted to solve the above technical problems is: a steel structure welding positioning fixture, including a base plate, on which arc-shaped baffles are symmetrically arranged, and on which positioning clamping mechanism and cleaning mechanism are symmetrically arranged. The positioning clamping mechanism includes two sets of support plates fixedly arranged on the upper surface of the base plate. A U-shaped support plate is fixedly connected to the upper end of one set of support plates. Both ends of the U-shaped support plate are hinged with hinge plates. An elastic plate is arranged between the two hinge plates. A spring is fixedly connected between the elastic plate and the U-shaped support plate. A first fixing column is fixedly connected to the bottom of the elastic plate. A rubber pad is fixedly connected to the upper surface of the elastic plate.

[0007] The above technical solution involves joining two steel pipes together and placing them simultaneously on the elastic plates of two sets of positioning and clamping mechanisms. Pressing down on the two steel pipes causes them to deform against the elastic plates, compressing the springs. The initial state of the elastic plates is an upward-bent state in the middle. When the steel pipes deform downwards to the predetermined curvature, the middle of the elastic plates bends downwards, causing both sides of the elastic plates to quickly move towards the steel pipes. Ultimately, the elastic plates form a C-shaped structure that clamps onto the surface of the steel pipes. Simultaneously, the hinge plates retract, thus quickly clamping and fixing the steel pipes. Because the elastic plates are C-shaped, their central axis is coaxial under the limiting action of the hinge plates. Therefore, the positioning and clamping mechanisms can be adjusted to quickly position the steel pipes, achieving rapid positioning and clamping. During disassembly, simply push the elastic plates upwards through the first fixed column to deform them. Under the action of the springs, the elastic plates deform back to their initial state, allowing the welded steel pipes to be removed. This method enables rapid positioning and clamping of the steel pipes and makes disassembly more convenient and faster, effectively improving work efficiency.

[0008] Furthermore, the cleaning mechanism includes fixed rods symmetrically arranged on the base plate, with a first fixed plate fixedly connected to the upper end of the fixed rods, and a gear rotatably arranged on the first fixed plate.

[0009] Furthermore, a second fixing post is fixedly installed on the gear, and a first connecting rod is fixedly connected to the second fixing post. A brush plate is fixedly connected to one end of the first connecting rod, and brush bristles are fixedly installed on one side edge surface of the brush plate.

[0010] The above technical solution uses gears to drive the second fixed column to rotate, which in turn drives the first connecting rod to rotate, which in turn drives the brush plate to rotate, which in turn drives the brush bristles to swing back and forth for cleaning.

[0011] Furthermore, there are two brush plates, which are symmetrically arranged on both sides of the positioning and clamping mechanism, and the brush bristles are in contact with the inner arc surface of the arc-shaped baffle.

[0012] The above technical solution uses brush bristles to clean the inner arc surface of the arc-shaped baffle, thereby automatically cleaning the welding slag and saving manpower.

[0013] Furthermore, a second fixing plate is fixedly connected to the lower end of the first fixing column, and a second connecting rod is symmetrically arranged at one end of the second fixing plate. A rack is fixedly connected to one end of the second connecting rod, and the rack is meshed with a gear.

[0014] With the above technical solution, the first fixed column moves up and down with the elastic plate, thereby driving the second connecting rod and rack to move up and down through the second fixed plate, which in turn drives the gear to rotate in both directions, thereby causing the bristles to oscillate. No additional drive source is needed to drive the gear to rotate, thus saving manufacturing costs.

[0015] Furthermore, slag collection grooves are symmetrically arranged on the upper surface of the base plate, and slag collection drawers are slidably arranged in the slag collection grooves. The slag collection drawers are located at the bottom of one side of the inner arc surface of the arc-shaped baffle.

[0016] The above technical solution enables the centralized collection and treatment of welding slag through a slag collection drawer.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) This utility model uses an elastic plate, a U-shaped support plate and a hinge plate. The steel pipe pushes against the elastic plate to form a C-shaped clamp on the surface of the steel pipe. At the same time, it drives the hinge plate to retract, thereby quickly clamping and fixing the steel pipe. It can achieve quick positioning and clamping of the steel pipe, and disassembly is also more convenient and quick, effectively improving work efficiency.

[0019] (2) This utility model, through the setting of an arc-shaped baffle, rack and cleaning mechanism, during the process of the elastic plate deforming into a C-shaped structure, drives the second fixed plate to move downward through the first fixed column, thereby driving the rack to move downward through the second connecting rod, thereby driving the gear to rotate, and thus driving the brush plate to rotate to the top of the arc-shaped baffle through the second fixed column and the first connecting rod. During the welding process, the welding slag splashes onto the inner wall of the arc-shaped baffle. After the welding is completed, during the process of removing the steel pipe, the first fixed column moves upward, thereby driving the gear to rotate in the opposite direction, thereby driving the brush bristles to move towards the welding slag collection drawer through the brush plate, thereby cleaning and collecting the welding slag on the inner wall of the arc-shaped baffle. This not only prevents welding slag splashing and improves safety performance, but also enables automatic cleaning and collection of welding slag, making it more convenient to use.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figure 1-7 As shown, a steel structure welding positioning fixture of this embodiment includes a base plate 1, on which arc-shaped baffles 2 are symmetrically arranged. A positioning clamping mechanism 5 and a cleaning mechanism 6 are symmetrically arranged on the base plate 1. The positioning clamping mechanism 5 includes two sets of support plates 51 fixedly arranged on the upper surface of the base plate 1. A U-shaped support plate 52 is fixedly connected to the upper end of one set of support plates 51. Hinged plates 53 are hinged to both ends of the U-shaped support plate 52. An elastic plate 55 is arranged between the two hinged plates 53. The elastic plate 55 and the U-shaped support plate 52 are connected... A spring 54 is fixedly connected between the two parts. A first fixed post 57 is fixedly connected to the bottom of the elastic plate 55. A rubber pad 56 is fixedly connected to the upper surface of the elastic plate 55, which can quickly clamp and fix the steel pipe. Since the elastic plate 55 has a C-shaped structure, under the limiting action of the hinge plate 53, the central axis of the elastic plate 55 is coaxial. Therefore, the steel pipe can be quickly positioned without adjusting the positioning clamping mechanism 5, thereby realizing the quick positioning and clamping of the steel pipe. Disassembly is also more convenient and quick, effectively improving work efficiency.

[0030] The cleaning mechanism 6 includes fixed rods 61 symmetrically arranged on the base plate 1. A first fixed plate 62 is fixedly connected to the upper end of the fixed rods 61. A gear 63 is rotatably arranged on the first fixed plate 62. A second fixed post 64 is fixedly arranged on the gear 63. A first connecting rod 65 is fixedly connected to the second fixed post 64. A brush plate 66 is fixedly connected to one end of the first connecting rod 65. Brush bristles 67 are fixedly arranged on one edge surface of the brush plate 66. There are two brush plates 66, which are symmetrically arranged on both sides of the positioning and clamping mechanism 5. The brush bristles 67 are connected to the arc-shaped baffle 2. The inner arc surface is contacted, and the lower end of the first fixed column 57 is fixedly connected to the second fixed plate 7. The second fixed plate 7 is symmetrically provided with a second connecting rod 8 at one end. The second connecting rod 8 is fixedly connected with a rack 9 at one end. The rack 9 is meshed with the gear 63. The upper surface of the base plate 1 is symmetrically provided with a slag collection groove 3. A slag collection drawer 4 is slidably provided in the slag collection groove 3. The slag collection drawer 4 is located at the bottom of one side of the inner arc surface of the arc-shaped baffle 2. It can not only prevent slag from splashing and improve safety performance, but also automatically clean and collect slag, making it more convenient to use.

[0031] The working principle of this embodiment is as follows: Two steel pipes are joined together and simultaneously placed on the elastic plates 55 of two sets of positioning and clamping mechanisms 5. The two steel pipes are pressed downwards, causing them to deform against the elastic plates 55 and compress the springs 54. The initial state of the elastic plates 55 is that the middle part is bent upwards. When the steel pipes deform downwards against the middle part of the elastic plates 55 to a predetermined curvature, the middle part of the elastic plates 55 bends downwards, causing both sides of the elastic plates 55 to quickly move towards the steel pipes. Ultimately, the elastic plates 55 form a C-shaped structure that clamps onto the surface of the steel pipes. Simultaneously, the hinge plates 53 retract, thereby quickly clamping and fixing the steel pipes. Because the elastic plates 55 form a C-shaped structure, under the limiting action of the hinge plates 53, the central axis of the elastic plates 55 is coaxial. Therefore, it is possible to quickly position the steel pipes without adjusting the positioning and clamping mechanisms 5, thus achieving rapid positioning and clamping. During disassembly, the elastic plate 55 is deformed by pushing upward with the first fixing post 57, and under the action of the spring 54, the elastic plate 55 deforms to its initial state, allowing the welded steel pipe to be removed. During the process of the elastic plate 55 deforming into a C-shaped structure, the second fixing plate 7 moves downward through the first fixing post 57, which in turn moves downward through the second connecting rod 8, causing the rack 9 to rotate, thereby rotating the gear 63. This, in turn, causes the brush plate 66 to rotate to the top of the arc-shaped baffle 2 through the second fixing post 64 and the first connecting rod 65. During the welding process, welding slag splashes onto the inner wall of the arc-shaped baffle 2. After welding is completed, during the removal of the steel pipe, the first fixing post 57 moves upward, causing the gear 63 to rotate in the opposite direction, which in turn causes the brush bristles 67 to move towards the welding slag collection drawer 4 through the brush plate 66, thereby cleaning and collecting the welding slag on the inner wall of the arc-shaped baffle 2.
