Technical Field
[0001] This utility model relates to the field of welding spacing positioning technology, and in particular to a welding spacing positioning and locking structure for steel truss. Background Technology
[0002] In the welding process, planar steel trusses are generally composed of two sets of chord bars and bent web bars. During the welding process, the two sets of chord bars and bent web bars are first joined together, and then welded by a welding mechanism. However, since the width of the bent web bars in planar steel trusses of different sizes is different, the spacing dimensions that the welding mechanism needs to adjust during welding are different. Therefore, it is necessary to adjust the welding position of the welding mechanism.
[0003] Currently, in existing technologies, when adjusting the welding spacing of a welding mechanism, the position of the welding mechanism is generally adjusted by the combined use of sensors and a moving mechanism to adapt to the welding of planar steel trusses of different sizes. However, during the welding process, the sensors are easily affected by welding spatter and dust, which can lead to a decrease in detection accuracy and cause deviations between the welding point and the steel bar joint, resulting in problems such as missed welds, incomplete welds, or weld misalignment. At the same time, the coordination between the sensors and the moving mechanism relies on a complex electrical control system, which is difficult to debug. Therefore, a steel truss welding spacing positioning and locking structure is proposed to solve the above problems. Utility Model Content

Detailed Implementation
[0031] 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.
[0032] Reference Figures 1-3This utility model provides an embodiment of a steel truss welding spacing positioning and locking structure, including a fixed frame 1, a cylinder 2 fixedly installed on the top of the fixed frame 1, a movable seat 4 fixedly connected to the output end of the cylinder 2, a round rod 3 fixedly connected to the inner surface of the fixed frame 1, the movable seat 4 being penetrated by the round rod 3 and slidably connected to the round rod 3, a spacing adjustment component 5 provided on the side of the movable seat 4, a welding component 6 provided on the outer wall of the movable seat 4, and a reinforcing rib 7 fixedly connected to the side of the fixed frame 1 away from the movable seat 4. By activating the cylinder 2, under the guidance of the round rod 3, the movable seat 4 can be stably raised and lowered, driving the spacing adjustment component 5 and the welding component 6 to move, thereby realizing the welding of the steel truss.
[0033] The spacing adjustment component 5 includes a fixed block 51 and a screw 54. An electric telescopic rod 52 is fixedly connected to the outer wall of the fixed block 51. The fixed block 51 is fixedly connected to the outer wall of the movable seat 4. A connector 53 is fixedly connected to the output end of the electric telescopic rod 52. A positioning nut 55 is threadedly connected to the thread of the screw 54. The connector 53 is fixedly connected to the screw 54. The screw 54 passes through the guide block 56 and is slidably connected to the guide block 56. A connecting block 57 is fixedly connected to the end of the screw 54 away from the connector 53. By rotating the positioning nut 55, the position of the positioning nut 55 on the screw 54 is adjusted, and then the electric telescopic rod 52 is activated, so that the contact distance between the positioning nut 55 and the guide block 56 is adjustable. This allows for stable adjustment of the distance of the welding component 6, which can quickly complete the adjustment and fixing of the welding spacing. It is suitable for truss products with different web member widths, and the spacing adjustment is precise, preventing problems such as missed welding, incomplete welding, and welding deviation, and reducing operation and maintenance costs.
[0034] Reference Figures 1-3 The welding assembly 6 includes a mounting frame 61, a welding torch 62, an elastic telescopic rod 63, and a positioning block 64. The mounting frame 61 is fixed to the connecting block 57. Two sets of spacing adjustment assemblies 5 are provided, and the two sets of spacing adjustment assemblies 5 are symmetrically arranged with the center line of the mounting frame 61 as the axis of symmetry. The welding torch 62 is fixedly mounted on the mounting frame 61, the elastic telescopic rod 63 is fixedly connected to the bottom of the mounting frame 61, and the positioning block 64 is fixedly connected to the bottom of the elastic telescopic rod 63. The moving seat 4 is driven to descend by the cylinder 2, which can drive the mounting frame 61 to descend, thereby driving the positioning block 64 to position the steel truss and improve the stability of the welding torch 62 during welding.
[0035] Furthermore, a guide rod is fixedly connected to the side of the mounting frame 61 near the movable seat 4, and a guide hole is opened on the side of the movable seat 4 near the mounting frame 61, and the guide rod matches the guide hole. In this way, the stability of the movable seat 4 when moving horizontally can be improved.
[0036] Reference Figure 2 and Figure 4The lower side of the positioning block 64 has an arc-shaped notch, and a rubber pad 641 is embedded in the arc-shaped notch. The use of the rubber pad 641 can increase the friction when fixing the steel truss. At the same time, the rubber pad 641 can deform, which improves the positioning effect of steel bars for steel trusses of different thicknesses.
[0037] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art.
[0038] Working principle: When in use, first adjust the welding spacing according to the width of the web reinforcement of the planar steel truss to be welded: rotate the positioning nuts 55 of the two sets of spacing adjustment components 5 to set their position on the screw 54, then start the electric telescopic rod 52, push the connector 53 to drive the screw 54 to slide along the guide block 56 until the positioning nut 55 abuts against the guide block 56. At this time, the two sets of spacing adjustment components 5 drive the installation frame 61 of the welding component 6 to move to the appropriate spacing, complete the initial calibration of the welding position, adapt to the needs of different sized trusses, and at the same time, the guide rod on one side of the installation frame 61 slides along the guide hole of the moving seat 4 to ensure the horizontal movement of the installation frame 61 is stable.
[0039] The steel truss, assembled by connecting the chord and web reinforcements, is then placed at the welding station. Cylinder 2 is activated, and guided by the round rod 3, the moving seat 4 drives the spacing adjustment assembly 5 and welding assembly 6 to descend smoothly. During descent, the positioning block 64 first engages with the chord of the steel truss, and the rubber pad 641 within the arc-shaped recess tightly adheres to the surface of the reinforcement bar, achieving positioning.
[0040] After positioning, the welding torch 62 is activated to weld the joint between the chord and web reinforcement bars. During the welding process, the positioning block 64 continuously presses and positions the bars to prevent displacement of the reinforcement bars, which could lead to misalignment or missed welds. If welding trusses of different sizes is required, the welding torch 62 is turned off after welding, the cylinder 2 drives each component to reset, and the finished truss is removed for future use.
[0041] 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.
