Description

Technical Field

[0001] This application relates to the technical field of submerged arc welding wire welding equipment, specifically to a gantry welding frame for submerged arc welding wire with multi-demand angle adjustment. Background Technology

[0002] In submerged arc welding (SAW) wire welding, the welding frame is a key piece of equipment, and its adjustable support angle directly affects the welding quality and efficiency. Traditional SAW wire welding frames have several shortcomings in angle adjustment. Firstly, the adjustment methods are often limited, allowing only simple overall angle adjustments and failing to provide individual, detailed angle adjustments for each support component. This makes precise positioning difficult when dealing with complex shapes and workpieces with varying support angle requirements, impacting welding quality. Secondly, achieving simultaneous adjustment of multiple support angles is typically complex, requiring significant time and effort for calibration and operation, greatly reducing welding efficiency. Furthermore, traditional welding frames lack flexibility in switching adjustment modes, failing to quickly adapt to the diverse angle adjustment needs of different welding processes.

[0003] Therefore, in order to improve the overall quality and efficiency of submerged arc welding wire, there is an urgent need for a gantry welding frame for submerged arc welding wire that can flexibly adjust to multiple angles, is easy to operate, and can quickly switch adjustment modes. Summary of the Invention

[0004] To address the aforementioned technical problems, this application solves the issue that in submerged arc welding, the welding frame support angle adjustment method is singular and the operation is complex, failing to flexibly meet the needs of individual and synchronous adjustment, thus affecting welding efficiency and quality.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a gantry welding frame for submerged arc welding wire with multi-demand angle adjustment, comprising a support assembly, an adjustment assembly, and a transmission assembly. The support assembly includes a base, a collection groove, a support rod, a mounting rod, and a support plate. The collection groove is fastened to the base. One support rod, one mounting rod, and one support plate constitute a set of support members. Two sets of support members constitute a pair and are symmetrically arranged on the base with the collection groove as the center line. Multiple pairs of support members are provided on the base. Each set of support members is individually adjusted by the adjustment assembly, and each pair of support members is adjusted in conjunction by the transmission assembly. The number of adjustment assemblies and transmission assemblies is the same as the number of support members.

[0006] The adjustment assembly includes an outer slider, a push-pull rod, a threaded rod, and an upper gear. The threaded rod is rotatably mounted on the base. The push-pull rod is threadedly engaged with the outer slider. The upper gear is fixedly mounted on the threaded rod. The two ends of the push-pull rod are rotatably connected to the outer slider and the support plate, respectively. The push-pull rod is driven to adjust the support plate by moving the outer slider on the threaded rod, thereby changing the support angle of a set of support components on the welded object.

[0007] The transmission assembly includes an external drive shaft and lower gears. The external drive shaft is slidably mounted on the base, and a lower gear is fixedly mounted at each of the two ends of the external drive shaft. The lower gears at both ends mesh with the upper gears on a set of support members. The power of the support members on both sides is transmitted by the external drive shaft and the lower gears at both ends, so as to realize the synchronous adjustment of the support angle of the welded object by a pair of support members.

[0008] Preferably, the adjusting assembly includes an inner bevel gear, an outer bevel gear, and a drive rod. The outer bevel gear is rotatably mounted on the base and has a handle for manually driving the outer bevel gear to rotate. The inner bevel gear and the outer bevel gear are respectively fixedly mounted on the end of the threaded rod near the outer bevel gear and on the outer bevel gear. The inner bevel gear and the outer bevel gear mesh with each other, and the power of the outer bevel gear is transmitted to the threaded rod.

[0009] Preferably, the transmission assembly includes a telescopic rod, a first spring, and an inner connecting shaft. Two telescopic rods are rotatably mounted on the outer transmission shaft, and each telescopic rod has a slider that engages with a groove on the base. Each lower gear is fitted with a first spring, and the two ends of the first spring are fixedly connected to the two ends of the lower gear. The ends of the two telescopic rods away from the outer transmission shaft are connected through the inner connecting shaft. The telescopic rods are extended or retracted by pulling them through the inner connecting shaft. The elastic force of the first spring drives the lower gear on the outer transmission shaft away from the upper gear, thereby achieving control of power engagement.

[0010] Preferably, the transmission assembly includes a swing rod, a rotating shaft, and a torsion spring. The rotating shaft is fixedly mounted on the base, the torsion spring is sleeved on the rotating shaft, the swing rod is rotatably mounted on the rotating shaft, and the two ends of the torsion spring are fixedly connected to the rotating shaft and the swing rod, respectively. An arc-shaped push block is provided at one end of the swing rod near the inner connecting shaft to adapt to the shape of the inner connecting shaft and ensure contact capability.

[0011] Preferably, the transmission assembly includes a bidirectional connecting block and a push rod. The bidirectional connecting block includes an intermediate block, a vertical connecting shaft, and a horizontal connecting shaft. The vertical connecting shaft and the horizontal connecting shaft are respectively fixed on one surface of the intermediate block. The vertical connecting shaft is rotatably connected to a hole in the swing rod, and the horizontal connecting shaft is rotatably connected to a hole at the end of the push rod near the swing rod. The push rod and the bidirectional connecting block push the swing rod to rotate on the rotating shaft, causing the lower gear to move away from the upper gear.

[0012] Preferably, the transmission assembly includes a pedal, a slide rod, and a second spring. One end of the push rod is rotatably connected to the shaft of the rotating shaft. The pedal includes a foot pedal, an intermediate shaft, and a sliding block. The two ends of the intermediate shaft are fixedly connected to the foot pedal and the sliding block, respectively. The intermediate plate is rotatably connected to a hole at the end of the push rod away from the swing rod. The sliding block has a vertical through hole, and the slide rod is slidably disposed on the through hole. The second spring is sleeved on the slide rod, and the two ends of the second spring are fixedly connected to the slide rod and the sliding block, respectively. The spring force of the second spring is used to reset and buffer the pedal.

[0013] The technical solution provided in this application has the following advantages compared with the prior art:

[0014] 1. This application, by setting an adjustment assembly consisting of an outer slider, a push-pull rod, and a threaded rod, achieves the goal of driving the outer slider to move on the threaded rod by rotating the threaded rod, thereby pushing or pulling the push-pull rod, and ultimately changing the angle of rotation of the support plate around the axis of the mounting rod. This design effectively solves the problem of the difficulty in flexibly adjusting the support angle of a single support component, improves the accuracy and convenience of adjustment, and can better meet the personalized needs of different weldments for the support angle.

[0015] 2. This application achieves efficient power transmission between the two side supports through a structural design where the external drive shaft and lower gear in the transmission assembly mesh with the upper gear in the adjustment assembly. When one side of the adjustment assembly operates, the other side support can simultaneously adjust its angle, thus solving the technical problem of not being able to simultaneously adjust the angles of paired support components. This design not only improves the consistency of angle adjustment of the two supports during welding but also further enhances welding efficiency and quality, ensuring the stability of the weldment during the welding process.

[0016] 3. This application ingeniously incorporates key components such as a telescopic rod, a first spring, and an inner connecting shaft into the transmission assembly. By precisely controlling the movement of the inner connecting shaft, the elastic force of the first spring separates the outer transmission shaft and the lower gear from the upper gear, achieving flexible control of power engagement. This innovative design effectively solves the practical problem of difficulty in switching between different adjustment modes, significantly improving the adaptability of the welding frame to various complex welding needs, and enabling operators to quickly and conveniently switch adjustment modes according to the actual welding situation.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] like Figures 1 to 6As shown, a gantry welding frame for submerged arc welding wire with multi-demand angle adjustment includes a support assembly 100, an adjustment assembly 200, and a transmission assembly 300. The support assembly 100 includes a base 101, a collection groove 102, a support rod 103, a mounting rod 104, and a support plate 105. The collection groove 102 is fastened to the base 101. The support rod 103 is fixedly installed on the base 101. A tube is provided on the support rod 103. The mounting rod 104 passes through the tube and also passes through a through hole on the inner side of the support plate 105. By bolts engaging with the threads on the mounting rod 104, the mounting rod 104 and the support plate 105 are relatively fixed on the tube of the support rod 103, allowing the support plate 105 to rotate around the axis of the tube of the support rod 103. A support rod 103, a mounting rod 104, and a support plate 105 constitute a set of support components. Two sets of support components form a pair and are symmetrically arranged on the base 101 with the collection groove 102 as the center line. Multiple pairs of support components are provided on the base 101. Each set of support components is individually adjusted by the adjustment component 200, and each pair of support components is adjusted in conjunction by the transmission component 300. The number of adjustment components 200 and transmission components 300 is the same as the number of support components.

[0027] Specifically, the angle adjustment of each pair of support members on the base 101 is connected through the transmission component 300. Thus, when it is necessary to adjust the support members on both sides, the angle of one set of support members on one side can be adjusted by the adjustment component 200 on one side first. And through the connection of the transmission component 300, the adjustment component 200 on the other side is driven to rotate, so that the other set of support members under the pair of support members is also adjusted in angle simultaneously.

[0028] When a set of support members needs to be adjusted individually, the control transmission component 300 disengages from the two side adjustment components 200, thereby releasing the power transmission between the two side adjustment components 200. At this time, the control adjustment component 200 can only adjust the support angle of the support member on that side.

[0029] like Figures 3 to 6 As shown, the adjustment assembly 200 includes an outer slider 201, a push-pull rod 202, a threaded rod 203, and an upper gear 207. The threaded rod 203 is rotatably mounted on the base 101 and has a threaded groove. The outer slider 201 is threaded and slidably mounted on the threaded rod 203. The push-pull rod 202 is threadedly engaged with the outer slider 201. The upper gear 207 is fixedly mounted on the threaded rod 203. The two ends of the push-pull rod 202 are rotatably connected to the outer slider 201 and the support plate 105, respectively. The movement of the outer slider 201 on the threaded rod 203 drives the push-pull rod 202 to adjust the support plate 105, thereby changing the support angle of a set of support members on the welded object.

[0030] When the threaded rod 203 rotates, the outer slider 201 moves along the axis of the threaded rod 203 via the thread. The outer slider 201 then pushes or pulls the push-pull rod 202 via the threaded rod 203. This push-pull rod 202, in turn, pushes or pulls the support plate 105 to rotate around the axis of the mounting rod 104, thereby changing the support angle of the support plate 105. The upper gear 207 is used for power transmission, driving the upper gear 207 and the threaded rod 203 on the other side to rotate via the transmission assembly 300.

[0031] like Figures 3 to 6 As shown, the transmission assembly 300 includes an outer transmission shaft 301 and a lower gear 302. The outer transmission shaft 301 is slidably mounted on the base 101. A lower gear 302 is fixedly mounted at each of the two ends of the outer transmission shaft 301. The lower gears 302 at both ends mesh with the upper gears 207 on a set of support members respectively. The power of the two support members is transmitted by the outer transmission shaft 301 and the lower gears 302 at both ends, so as to realize the synchronous adjustment of the support angle of the welding object by a pair of support members.

[0032] Specifically, power is transmitted through the meshing relationship between the lower gear 302 and the upper gear 207. The upper gear 207 drives the lower gear 302 to rotate, and the lower gear 302 drives the lower gear 302 on the other side to rotate through the outer transmission shaft 301. In turn, the lower gear 302 drives the upper gear 207 and the threaded rod 203 on that side to rotate, thereby driving the outer slider 201 on that side and adjusting the support plate 105 on that side.

[0033] like Figure 1 , Figures 4 to 6 As shown, the adjustment assembly 200 includes an inner bevel gear 204, an outer bevel gear 205, and a drive rod 206. The outer bevel gear 205 is rotatably mounted on the base 101, and a handle for manually driving the outer bevel gear 205 to rotate is provided on the outer bevel gear 205. The inner bevel gear 204 and the outer bevel gear 205 are respectively fixedly mounted on the end of the threaded rod 203 near the outer bevel gear 205 and on the outer bevel gear 205. The inner bevel gear 204 and the outer bevel gear 205 mesh with each other, and the power of the outer bevel gear 205 is transmitted to the threaded rod 203.

[0034] Specifically, when it is necessary to adjust the support angle of the support component, the operator manually controls the handle on the outer bevel gear 205, causing the handle to drive the outer bevel gear 205 to rotate around its axis. As a result, the drive rod 206 on the outer bevel gear 205 also rotates, and through meshing with the inner bevel gear 204, drives the inner bevel gear 204 and the threaded rod 203 to rotate on the base 101. The threaded rod 203 then drives the outer slider 201 to move through the thread. The push-pull rod 202 controls the support plate 105 to rotate around the axis of the mounting rod 104, thereby achieving the adjustment of the support angle.

[0035] like Figure 5 and Figure 6 As shown, the transmission assembly 300 includes a telescopic rod 303, a first spring 304, and an inner connecting shaft 305. Two telescopic rods 303 are rotatably mounted on the outer transmission shaft 301. Each telescopic rod 303 has a slider that engages with a groove on the base 101. The slider supports the movement of the outer transmission shaft 301 and the lower gear 302. Each lower gear 302 is fitted with a first spring 304, and both ends of the first spring 304 are fixedly connected to both ends of the lower gear 302. The ends of the two telescopic rods 303 away from the outer transmission shaft 301 are connected through the inner connecting shaft 305. The inner connecting shaft 305 pulls the telescopic rods 303 to extend or retract. The elastic force of the first spring 304 drives the lower gear 302 on the outer transmission shaft 301 away from the upper gear 207, thereby achieving control of power engagement.

[0036] Specifically, when adjusting one side of the support, the lower gear 302 on the outer drive shaft 301 must first be moved away from the upper gear 207 to disengage it. This prevents the upper gear 207 on the other side from being driven to rotate via the lower gear 302 and the outer drive shaft 301 when the threaded rod 203 is rotated. In use, the inner connecting shaft 305 is moved away from the upper gear 207. Each end of the inner connecting shaft 305 pulls one end of a telescopic rod 303. The telescopic structure of the telescopic rod 303 extends and stretches the first spring 304. When the elastic force of the first spring 304 reaches a certain level, it pulls the outer drive shaft 301, overcoming the friction between the slider on the telescopic rod 303 and the base 101. This causes the outer drive shaft 301 and the lower gears 302 at both ends to move away from the upper gear 207, thus cutting off the power transmission. When the telescopic rod 303 moves, the locking structure between the upper slider of the telescopic rod 303 and the sliding groove of the base 101 ensures the moving surface of the telescopic rod 303 and prevents the end of the telescopic rod 303 near the upper gear 207 from tilting up and detaching from the base 101.

[0037] like Figure 5 and Figure 6 As shown, the transmission assembly 300 includes a swing rod 306, a rotating shaft 307, and a torsion spring 308. The rotating shaft 307 is fixedly mounted on the base 101, and the torsion spring 308 is sleeved on the rotating shaft 307. The swing rod 306 is rotatably mounted on the rotating shaft 307. The two ends of the torsion spring 308 are fixedly connected to the rotating shaft 307 and the swing rod 306, respectively. An arc-shaped push block is provided at one end of the swing rod 306 near the inner connecting shaft 305 to adapt to the shape of the inner connecting shaft 305 and ensure contact capability.

[0038] Specifically, the operator controls one end of the swing lever 306 from the outside, causing it to rotate on the rotating shaft 307 and twist the torsion spring 308. Subsequently, the torsion spring 308 resets, and then the arc-shaped slider on the other side of the swing lever 306 contacts the inner connecting shaft 305, thereby pushing the telescopic rod 303 on the inner connecting shaft 305 to slide on the groove of the base 101, ultimately driving the lower gear 302 away from the upper gear 207.

[0039] like Figure 5 and Figure 6 As shown, the transmission assembly 300 includes a bidirectional connecting block 309 and a push rod 310. The bidirectional connecting block 309 includes an intermediate block, a vertical connecting shaft, and a horizontal connecting shaft. The vertical connecting shaft and the horizontal connecting shaft are respectively fixed on one surface of the intermediate block. The vertical connecting shaft is rotatably connected to the hole of the swing rod 306, and the horizontal connecting shaft is rotatably connected to the hole of the push rod 310 near the end of the swing rod 306. The push rod 310 and the bidirectional connecting block 309 push the swing rod 306 to rotate on the rotating shaft 307, thereby driving the lower gear 302 away from the upper gear 207.

[0040] Specifically, the end of the swing rod 306 away from the inner connecting shaft 305 is provided with a telescopic structure. When the bidirectional connecting block 309 pushes this end of the swing rod 306, the end of the swing rod 306 extends to adapt to the push of the bidirectional connecting block 309. When the bidirectional connecting block 309 returns to its original position, it pulls the telescopic structure of the swing rod 306 to retract. The push rod 310 is initially tilted. Thus, by pushing the upper end of the push rod 310, the lower end of the push rod 310 pushes the horizontal connecting shaft of the bidirectional connecting block 309. This, in turn, drives the vertical connecting shaft to follow the movement of the lower end of the push rod 310 through the intermediate block. Consequently, the vertical connecting shaft of the bidirectional connecting block 309 drives the end of the swing rod 306 away from the inner connecting shaft 305 to move, thereby causing the swing rod 306 to rotate around the axis of the rotating shaft 307. The end of the swing rod 306 away from the inner connecting shaft 305 slides, changing the length of the swing rod 306 to adapt to the rotation of the swing rod 306 and the push of the bidirectional connecting block 309.

[0041] like Figure 5 and Figure 6As shown, the transmission assembly 300 includes a pedal 311, a slide rod 312, and a second spring 313. One end of the push rod 310 is rotatably connected to the shaft of the rotating shaft 307 via the swing rod 306. The pedal 311 includes a foot pedal, an intermediate shaft, and a sliding block. The two ends of the intermediate shaft are fixedly connected to the foot pedal and the sliding block, respectively. The intermediate plate is rotatably connected to the hole at the end of the push rod 310 away from the swing rod 306. The sliding block is provided with a vertical through hole, and the slide rod 312 is slidably disposed on the through hole. The second spring 313 is sleeved on the slide rod 312, and the two ends of the second spring 313 are fixedly connected to the slide rod 312 and the sliding block, respectively. The spring force of the second spring 313 resets and buffers the pedal 311.

[0042] The operator presses the pedal 311 with their foot, which in turn moves the upper end of the push rod 310 vertically downward via the intermediate shaft. The sliding block of the pedal 311 slides vertically downward on the slide rod 312, compressing the second spring 313 on the slide rod 312. This buffers the pedal 311 and allows it to reset after operation. The sliding of the sliding block on the slide rod 312 and the elastic force of the second spring 313 support the upper end of the push rod 310, the foot pedal of the pedal 311, and the intermediate shaft. When the upper end of the push rod 310 moves vertically downward, its lower end horizontally pushes the bidirectional connecting block 309, which in turn drives the swing rod 306.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
