Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure welding fixtures, specifically a steel structure welding fixture. Background Technology

[0002] Steel structure is a building structure that uses steel, such as steel beams, steel columns, and steel trusses, as the main load-bearing components. It has the advantages of steel's excellent tensile and compressive strength, making it suitable for large-span and super high-rise buildings. At the same time, compared with concrete, steel has a higher strength and weight ratio, which can reduce the foundation load and lower the cost.

[0003] When these steel structures are processed and welded, the welding angles of the connectors at different locations are also different. When welding these steel structures with different angles, it often relies on the experience of the workers. At the same time, some existing welding fixtures lack the function of adjusting the angle. These problems may cause the angle to deviate during the welding of the steel structure, affecting the subsequent use effect.

[0004] Meanwhile, application number CN 220679860 U discloses a steel structure welding fixture, including a fixture body, the fixture body including a base, a support seat and a fixed seat respectively welded on the base, a movable seat movably installed on the top of the fixed seat and the support seat, a lifting mechanism fixedly installed on the movable seat, a fixed frame welded to the bottom of the movable seat, a fixed groove opened on both the support seat and the fixed seat, the fixed frame movably installed inside the fixed groove, and a slot opened on the support seat.

[0005] However, the following problems were found in the implementation of the relevant technology: the utility model cannot be adjusted for steel structures with different welding angle requirements. When encountering such a welding machine, it can only be done by the experience of the workers, but it is easy to cause angle deviation. Utility Model Content

[0025] 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.

[0026] like Figures 1 to 4 As shown, this utility model provides a steel structure welding fixture, including a welding table 1. An adjustment component 2 is slidably disposed on the top surface of the welding table 1. The adjustment component 2 includes a motor 201.

[0027] A main gear 202 is fixedly mounted at the end of the main shaft of the motor 201. A driven gear 203 meshes with the outer side of the main gear 202. A connecting sleeve 204 is fixedly mounted on the outer side of the driven gear 203. A lead screw 206 is fixedly mounted on the outer side of the connecting sleeve 204. A movable sleeve 205 is threadedly connected to the outer side of the lead screw 206. An inner side plate 207 is slidably fitted on the outer side of the movable sleeve 205, and the movable sleeve 205 is located inside the inner side plate 207. The motor 201 drives the main gear 202, which drives the driven gears 203 on both sides. The connecting sleeve 204 drives the lead screw 206 to rotate, and the lead screw 206 drives the movable sleeve 205 to slide. When the movable sleeve 205 slides, it pushes the inner side plate to open or retract to adjust the angle. This solves the problem that traditional welding fixtures cannot adapt to steel structures with different angle welding requirements, increases the flexibility and adaptability of the welding fixture, improves the use effect and utilization rate of the fixture, and ensures the welding quality of the steel structure.

[0028] Specifically, a first fixing plate 301 is fixedly installed on the outside of the motor 201, and a fixing frame 3 is fixedly installed on the outside of the first fixing plate 301. The fixing frame 3 is engaged with the connecting sleeve 204. The fixing frame 3 is used to fix some parts in the adjustment assembly 2 to maintain its stability during operation.

[0029] Furthermore, a slide rail 13 is fixedly installed on the top of the welding table 1, and a second slider 15 is slidably installed on the top of the slide rail 13. The second slider 15 is fixedly connected to the fixed frame 3. The second slider 15 can reduce the friction of the fixed frame 3 when sliding, thereby increasing its sliding efficiency.

[0030] Furthermore, the inner side plate 207 is rotatably provided with a fixing pin 4, and the bottom of the fixing pin 4 is fixedly provided with a first slider 14, and the first slider 14 is slidably connected to the slide rail 13. The fixing pin 4 is used to fix the inner side plates 207 on both sides, and at the same time promotes sliding through the first slider 14.

[0031] It is worth noting that fixing blocks 8 are fixedly installed on both sides of the top surface of the welding table 1. A shaft core 10 is fixedly installed on the inner side of the fixing block 8, and a spring 9 is sleeved on the outer side of the shaft core 10. One side of the spring 9 is fixedly connected to the fixing block 8, and a rear side plate 6 is attached to the other side of the spring 9. A second placement plate 7 is fixedly installed on the inner side of the spring 9. The spring 9 supports the rear side plate 6, thereby forming a certain resistance, which fixes the other side of the steel structure welding machine and forms a relatively stable clamping mechanism with the adjustment component 2. At the same time, the connection between the spring 9 and the rear side plate 6 is relatively flexible and facilitates the free movement of the rear side plate 6. The second placement plate 7 is used to place the steel structure.

[0032] It is worth noting that a first placement plate 5 is fixedly installed on the outside of the fixing frame 3, and the height of the first placement plate 5 is the same as that of the second placement plate 7. Both the first placement plate 5 and the second placement plate 7 are used to prevent the steel structure welding machine, and at the same time, they can better maintain the stability of the steel structure welded parts.

[0033] It is worth mentioning that a support plate 11 is fixedly installed on one side of the top surface of the welding table 1, and a hydraulic telescopic shaft 12 is fixedly installed on the outer side of the support plate 11. A second fixing plate 302 is fixedly installed at the end of the main shaft of the hydraulic telescopic shaft 12, and the second fixing plate 302 is fixedly connected to the fixing frame 3. The adjustment component 2 and the fixing frame 3 are moved by the hydraulic telescopic shaft 12, thereby fixing the welding machine.

[0034] Among them, the motor 201 and the hydraulic expansion joint 12 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0035] Working principle:

[0036] When using the steel structure welding fixture, firstly, adjust the angle of the fixture according to the welding requirements of the steel structure. Turn on the motor 201 in the adjustment assembly 2. The motor 201 is installed on the first fixed plate 301 inside the fixed frame 3. The motor 201 drives the main gear 202, which in turn drives the driven gears 203 on both sides. The driven gears 203 are connected to the fixed frame 3 via a connecting sleeve 204. The connecting sleeve 204 drives the lead screw 206 to rotate, and the lead screw 206 drives the movable sleeve 205 to slide. When the movable sleeve 205 slides, it pushes the inner plate 207 to open or retract, thereby adjusting the angle. The other end of the inner plate 207 is connected to the first slider 14 via a fixing pin 4. Then... The hydraulic telescopic shaft 12 on the outside of the support plate 11 is opened. The hydraulic telescopic shaft 12 pushes the second fixed plate 302, thereby pushing the adjustment component 2 forward. The steel structure is clamped, and the other side of the steel structure is fixed by the rear plate 6. The spring 9 on the outside of the shaft core 10 is used to support the rear side of the rear plate 6 to provide sufficient resistance. The fixing block 8 is used to fix and support the spring 9 and the shaft core 10. The first placement plate 5 and the second placement plate 7 are used to place the steel structure to prevent it from being obstructed by the lead screw 206. The slide rail 13 on the inner side of the top of the welding table 1 is used to promote the sliding of the fixing frame 3 and the inner plate 207 through the first slider 14 and the second slider 15, thereby reducing the friction during sliding.
