DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific embodiments.

[0033] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on the present application; in order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0034] Embodiment 1: This embodiment provides a channel steel butt welding device, such as Figure 1-Figure 4As shown, it includes a welding table 1, on which a group of welding components 2 for welding channel steel and two groups of adjustment components 3 for adjusting the position of channel steel are installed; the adjustment component 3 includes a limit adjustment unit for self-centering clamping of channel steel and a conveying unit for transmitting channel steel; the welding table 1 includes a first mounting arm 103 and a second mounting arm 104, and the two adjustment components 3 are respectively installed on the first mounting arm 103 and the second mounting arm 104, and the first mounting arm 103 and the second mounting arm 104 can rotate relative to each other; the limit adjustment unit includes a limit seat 301, and the limit seat 301 is rotatably connected to a limit gear ring 302 and a limit plate 308, and the limit plate A rotational resistance is preset between 308 and the limit seat 301; the limit plate 308 is rotatably connected to multiple driven gears 304 and slidably connected to multiple limit plates 305, the limit plates 305 are meshed with the driven gears 304, the driven gears 304 are meshed with the limit gear ring 302, and a fifth motor 306 is installed on the limit seat 301, and a limit gear 307 is installed at the output end of the fifth motor 306, and the limit gear 307 is meshed with the limit gear ring 302; the size of the rotational resistance satisfies that when the limit gear ring 302 rotates, the driven gear 304 is first driven to make the limit plate 305 clamp the channel steel, and then the limit gear ring 302 drives the driven gear 304 to overcome the rotational resistance and make the limit plate 308 rotate.

[0035] When the conveying unit transports the channel steel to the limit adjustment unit, the fifth motor 306 drives the limit gear 307 to make the limit gear ring 302 start to rotate, and the limit gear ring 302 drives the driven gear 304 to rotate, and the driven gear 304 drives the limit plate 305 to slide, and the area surrounded by the multiple limit plates 305 begins to shrink, and the limit plate 305 begins to approach the channel steel. Since the multiple limit plates 305 move at the same time, they have a self-centering effect on the channel steel. When the limit plate 305 presses the channel steel, the limit plate 305 cannot continue to slide. At this time, the driven gear 304 cannot rotate. Since the limit gear ring 302 is still rotating, the driving force overcomes the preset rotation resistance and causes the limit plate 308 to start to rotate through the multiple driven gears 304. The rotation of the limit plate 308 causes the channel steel to rotate synchronously, and then the angle of the channel steel is rotated and adjusted to ensure that there is no relative rotation angle of the channel steels on the two limit adjustment units, thereby improving the docking accuracy and thus improving the welding quality.

[0036] Embodiment 2: This embodiment is further expanded on the basis of embodiment 1, specifically as follows Figure 6 As shown, the limit plate 305 is slidably connected to the telescopic seat 311 , and a compensating spring 312 is provided between the limit plate 305 and the telescopic seat 311 .

[0037] Before the telescopic seat 311 is set, the shape ratio of the limit plate 305 needs to be adjusted accordingly according to the length-width ratio of the cross section of the channel steel, so that each limit plate 305 can be pressed on the outside of the channel steel at the same time when it is contracted; after the telescopic seat 311 and the compensating spring 312 are set, each limit plate 305 can be of the same shape, and the length-width difference of the channel steel is compensated by the compensating spring 312. When multiple limit plates 305 are contracted, each compensating spring 312 is in a compressed state. Due to the compensation of the length-width difference, the compression amount of the compensating spring 312 is inconsistent. In this way, the specifications of the limit plates 305 are unified to reduce the difficulty of manufacturing; at the same time, when operating on channel steels of different specifications, there is no need to replace the limit plates 305, which improves the operating efficiency.

[0038] like Figure 6 As shown, the telescopic seat 311 is rotatably connected to the limiting roller 310, and the limiting roller 310 is made of a material with a hardness greater than that of steel, such as a titanium alloy. By setting the limiting roller 310, when the limiting adjustment unit clamps the channel steel, the conveying resistance of the conveying unit can be reduced; the hardness of the limiting roller 310 is set to prevent the channel steel from scratching the limiting roller 310, which will cause the subsequent limiting roller 310 to be inconvenient to roll or even get stuck in the channel steel.

[0039] like Figure 5 As shown, a friction plate 309 is provided between the limit plate 308 and the limit seat 301, and the friction plate 309 provides rotation resistance. By increasing the friction between the limit plate 308 and the limit seat 301, the rotation resistance between the limit seat 301 and the limit plate 308 is preset.

[0040] like Figure 7 As shown, the conveying unit includes a conveying arm 303 mounted on a limit seat 301, two sixth motors 313 are mounted on the conveying arm 303, and a conveying roller 314 is mounted on the output end of the sixth motor 313. The sixth motor 313 is started to rotate the conveying roller 314, and the two conveying rollers 314 slightly clamp the channel steel to move it.

[0041] like Figure 8-Figure 9As shown, the welding table 1 also includes a base 101, and a plurality of rollers 102 are arranged on the base 101. The first mounting arm 103 is fixedly mounted on the roller 102. A speed change unit is arranged on the base 101, and the speed change unit includes a fixed gear ring 105 and a connecting seat 106 fixedly mounted on the base 101. The connecting seat 106 is rotatably connected to the second mounting arm 104. A first motor 109 is arranged on the base 101, and a third speed gear 110 is arranged at the output end of the first motor 109. The second mounting arm 104 is rotatably connected to the first speed gear 107, and the first speed gear 107 is meshed with the third speed gear 110. The first speed gear 107 is fixedly connected to the second speed gear 108, and the second speed gear 108 is meshed with the fixed gear ring 105.

[0042] When the channel steel needs to be welded at a certain angle, the first motor 109 is started, which drives the third speed gear 110 to rotate the first speed gear 107, and the first speed gear 107 drives the second speed gear 108 to rotate. Since the second speed gear 108 is meshed with the fixed ring gear 105, the second speed gear 108 starts to drive the second mounting arm 104 to revolve. Through the above arrangement, the power of the first motor 109 can be decelerated and torque-increased and then transmitted to the second mounting arm 104, so that the second mounting arm 104 drives a group of adjustment components 3 to rotate.

[0043] like Fig.10 As shown, the welding assembly 2 includes an omnidirectional adjustment unit and an omnidirectional welding unit. The omnidirectional welding unit is installed on the omnidirectional adjustment unit. The omnidirectional adjustment unit is used to adjust the spatial position of the omnidirectional welding unit to weld different positions of the channel steel. The omnidirectional welding unit is used to change the welding angle to achieve welding of different angles for a single welding point.

[0044] like Fig.10 As shown, the omnidirectional adjustment unit includes a welding slag collecting box 203 fixedly mounted on the connecting seat 106, a third motor 207 is mounted on the welding slag collecting box 203, a gear ring seat 205 is mounted on the output end of the third motor 207, the gear ring seat 205 is rotatably connected to the welding gear ring 201, a second motor 204 is mounted on the gear ring seat 205, a welding gear 206 is mounted on the output end of the second motor 204, the welding gear 206 is meshed with the welding gear ring 201, and the omnidirectional welding unit is mounted on the welding gear ring 201.

[0045] When the second mounting arm 104 rotates, the third motor 207 will also rotate, always keeping the plane where the radial section of the welding gear ring 201 is located parallel to the plane where the joints of the two channel steels are located, ensuring that the welding head of the omnidirectional welding unit is on the plane where the joints are located; when the second motor 204 is started, the welding gear 206 drives the welding gear ring 201 to rotate, so that the omnidirectional welding unit can go around the channel steel and perform welding operations on different parts of the channel steel.

[0046] like Fig.11 As shown, the omnidirectional welding unit includes a cylinder 202 installed on the welding gear ring 201, a connecting rod seat 208 is installed on the cylinder 202, an arc-shaped slide groove seat 215 is fixedly connected to the connecting rod seat 208, two first connecting rods 209 are rotatably connected to the connecting rod seat 208, a fourth motor 210 is arranged on the connecting rod seat 208, a fourth connecting rod 211 is installed at the output end of the fourth motor 210, two second connecting rods 212 are rotatably connected to the fourth connecting rod 211, a welding rod 214 is slidably connected to the arc-shaped slide groove seat 215, two third connecting rods 213 are rotatably connected to the welding rod 214, the second connecting rod 212, the first connecting rod 209 and the third connecting rod 213 on the same side are rotatably connected, and a welding head is installed on the welding rod 214.

[0047] The distance between the welding rod 214 and the channel steel is adjusted by telescoping the cylinder 202 to ensure that the welding head contacts the weld. When the fourth motor 210 is started, the fourth connecting rod 211 drives the two second connecting rods 212 to swing. Due to the restrictions of the first connecting rod 209 and the third connecting rod 213, when the second connecting rod 212 drives the welding rod 214 to slide on the arc-shaped slide seat 215, the position of the welding point remains unchanged, thereby achieving welding of the weld at different angles using the welding head as needed, thereby improving the welding effect.

[0048] Working principle: According to the welding requirements of the two channel steels, start the first motor 109 to adjust the angle between the first mounting arm 103 and the second mounting arm 104, start the third motor 207 to adjust the deflection angle of the welding gear ring 201; then put the channel steel on the conveying unit, and use the conveying unit to transport the channel steel to the limit adjustment unit. At this time, the fifth motor 306 is started, and multiple limit rollers 310 begin to clamp the channel steel, and then fine-tune the deflection position of the channel steel. Then the conveying unit continues to transport the channel steel until the two channel steels are spliced ​​at the welding gear ring 201; then the conveying unit stops transporting, and the second motor 204 is started to make the omnidirectional welding unit start to revolve around the channel steel for welding; after welding is completed, the fifth motor 306 reverses, and the limit roller 310 moves away from the channel steel, and then the welded channel steel can be manually removed.

[0049] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
