For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0060] Embodiment 1

[0061] See also Figures 1 to 9 As shown, the synchronous welding device provided by the present application can be applied to the following scenarios: for example, when the processing equipment of the next process is a winding machine, the welded workpieces such as pipes are wound on the winding parts of the winding machine, and as the winding machine runs, the welded workpieces are pulled toward the winding machine.

[0062] It should be noted that the processing equipment of the next step may also be other equipment that can provide the workpiece with a force in a direction away from the welding structure, and the present application is not limited to a winding machine.

[0063] The synchronous welding device provided in the present application includes a welding mechanism 101 and a first guide rail assembly 102; wherein the welding mechanism 101 can weld the joint between the first workpiece 103 and the second workpiece 104 in the workpieces to be welded, and the welding mechanism 101 can carry the second workpiece 104. At the same time, the first clamping mechanism 123 clamps the first workpiece 103 located on the discharge port side of the welding mechanism 101; when the winding machine pulls the first workpiece 103 that is closer in position, it can drive the first clamping mechanism 123 to move synchronously.

[0064] Specifically, the first guide rail assembly 102 includes a first slide rail 105 and a first slide table 106 slidably disposed on the first slide rail 105. The welding mechanism 101 and the first clamping mechanism 123 are connected to the first slide table 106, that is, the positions of the welding mechanism 101 and the first clamping mechanism 123 are relatively fixed, and when the winding machine pulls the first workpiece 103, it can drive the first clamping mechanism 123 and the welding mechanism 101 to move synchronously. In other words, while the first workpiece 103 and the second workpiece 104 are welded, the first workpiece 103 and the second workpiece 104 can move toward the winding machine at the same time.

[0065] When the winding machine pulls the first workpiece 103, the welding mechanism 101 and the first clamping mechanism 123 can reciprocate along the guide direction of the first slide rail 105 to prevent the movement direction from shifting; and the first guide rail assembly 102 can reduce the friction of the welding mechanism 101 to achieve the synchronization of the welding process and the transportation process, thereby improving the processing efficiency.

[0066] In an optional scheme of this embodiment, the welding mechanism 101 includes a roller 107 and a welding assembly 108 installed on the roller 107. On the one hand, the setting of the roller 107 can provide an installation position for the welding assembly 108; on the other hand, the roller 107 is formed with a accommodating cavity so that the first workpiece 103 and the second workpiece 104 can pass through the accommodating cavity along the axial direction of the roller 107; and the roller 107 is rotatably arranged on the first slide 106. When the first driving device 109 drives the roller 107 to rotate around the axis of the roller 107 relative to the first slide 106 through the gear assembly, the positions of the first workpiece 103 and the second workpiece 104 are fixed at this time, and the roller 107 drives the welding assembly 108 to move around the first workpiece 103 and the second workpiece 104 to perform ring welding on the butt joint of the first workpiece 103 and the second workpiece 104.

[0067] Specifically, the welding assembly 108 is specifically a welding gun, and a wire feeder 110 for feeding welding wire to the welding gun may also be installed on the drum 107 .

[0068] In an optional scheme of this embodiment, in order to realize multi-dimensional movement of the welding assembly 108 to achieve precise welding, a second guide rail assembly 112, a second drive device 113, a third guide rail assembly 114 and a third drive device 115 are further provided; specifically, the second guide rail assembly 112 includes a second slide rail and a second slider, and the second drive device 113 drives the second slider to move relative to the second slide rail; the third guide rail assembly 114 includes a third slide rail and a third slider slidably arranged on the third slide rail, and the third drive device 115 drives the third slider to move relative to the third slide rail; the welding assembly 108 is connected to the third slider.

[0069] The second slide rail is installed on the roller 107, and the guiding direction of the second slide rail is the axial direction of the roller 107, that is, the welding assembly 108 can be reciprocated along the axial direction of the roller 107, that is, the welding assembly 108 can be aligned with the welding position in the axial direction of the first workpiece 103, that is, the second workpiece 104; the third slide rail is connected to the second slider through the fixed plate 111, and the guiding direction of the third slide rail is the radial direction of the roller 107, that is, the welding assembly 108 can be close to or away from the welding position in the radial direction of the roller 107 to adapt to workpieces of different sizes.

[0070] In an optional scheme of this embodiment, a swing mechanism 116 is further arranged between the welding assembly 108 and the third slider; the welding assembly 108 is rotatably mounted on the third slider; the swing mechanism 116 includes a fourth driving device 117 and a swing transmission assembly 118, the fourth driving device 117 is connected to the roller 107, the fourth driving device 117 can drive the welding assembly 108 to swing back and forth along the axial direction of the roller 107 by a preset angle through the swing transmission assembly 118, when the roller 107 rotates, the swinging welding assembly 108 can perform crescent-shaped cloud strip welding on the joint between the first workpiece 103 and the second workpiece 104; when welding using this cloud strip method, the end of the welding rod swings left and right in a crescent shape along the welding direction, which has the advantages of good metal melting, long insulation time, easy gas precipitation, and welding slag is also easy to float to the weld surface, resulting in high weld quality.

[0071] Specifically, the swing transmission assembly 118 includes a swing first gear and a swing second gear that are meshed and connected. The swing first gear is connected to the driving end of the fourth driving device 117, and the swing second gear is connected to the welding assembly 108.

[0072] As shown in the figure, the drum 107 shown in this embodiment has a window, the welding assembly 108, the swing transmission assembly 118, the third guide assembly 114 and the third driving device 115 are arranged at the window, and the second guide assembly 112 and the second driving device 113 are installed on the outer wall of the drum 107. With such an arrangement, the volume of the drum 107 is small, the space occupied by the device is smaller, and the window is convenient for observing the welding situation. The volume of the drum 107 can also be increased so that the above-mentioned components can also be installed in the accommodating cavity formed inside the drum 107.

[0073] In the optional scheme of this embodiment, in order to ensure that the docking position of the first workpiece 103 and the second workpiece 104 is accurate and the welding between the two is reliable, it is defined that the welding mechanism 101 also includes a relatively arranged rotating clamping assembly 119; the rotating clamping assembly 119 includes a fifth driving device 120 and a clamping portion 121 connected to each other, the fifth driving device 120 is installed on the roller 107, and the fifth driving device 120 can drive the clamping portion 121 along the radial direction of the roller 107 to approach or move away from the docking point of the first workpiece 103 and the second workpiece 104. When the relatively arranged clamping portions 121 are close to the docking point at the same time, the clamping function is realized, and vice versa. The releasing function is realized.

[0074] The clamping portion 121 includes a plurality of first clamping wheels 122, which are respectively in contact with the surfaces of the first workpiece 103 and the second workpiece 104. When the roller 107 rotates, the plurality of first clamping wheels 122 can roll circumferentially on the first workpiece 103 and the second workpiece 104. There is rolling friction between the first clamping wheels 122 and the first workpiece 103 and the second workpiece 104, and the friction force is smaller. While realizing the clamping function, it does not affect the circumferential movement of the roller 107 and the circumferential welding effect on the welding point.

[0075] Embodiment 2

[0076] The synchronous welding device in the second embodiment is an improvement on the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0077] In the optional solution of this embodiment, a first clamping mechanism 123 is provided on the discharge port side of the welding mechanism 101. While the first clamping mechanism 123 realizes the function of clamping the first workpiece 103, the first clamping mechanism 123 can also provide two-point support for the first workpiece 103 with the rotating clamping assembly 119, and the support effect is better. The first clamping mechanism 123 includes a first clamping assembly arranged relatively, and the first clamping assembly is installed on the first slide 106; the first clamping assembly includes a sixth driving device 125 and a first clamping member 126, and the sixth driving device 125 can drive the first clamping member 126 to approach or move away from the first workpiece 103 to realize the clamping function and the release function; the first clamping member 126 is formed with a first clamping notch to fit with the outer surface of the first workpiece 103 to realize the clamping of the first workpiece 103.

[0078] Furthermore, a second clamping mechanism 124 is provided on the feeding port side of the welding mechanism 101. Similarly, the second clamping mechanism 124 can realize the function of clamping the second workpiece 104, and the second clamping mechanism 124 can also provide two-point support for the second workpiece 104 with the rotating clamping assembly 119, so as to achieve a better support effect. The second clamping mechanism 124 includes a lap wheel 129 and a second clamping assembly arranged opposite to each other, and the second clamping assembly is installed on the first slide 106; the second clamping assembly includes a seventh driving device 127 and a second clamping member 128, and the seventh driving device 127 can drive the second clamping member 128 to approach or move away from the second workpiece 104 to realize the clamping function and the release function; the second clamping member 128 is formed with a second clamping notch to fit with the outer surface of the second workpiece 104 to realize the clamping of the second workpiece 104.

[0079] The overlap wheel 129 is rotatably mounted on the first slide 106 , and the workpiece to be welded can overlap the overlap wheel 129 . When the workpiece to be welded is transported to the welding mechanism 101 , the overlap wheel 129 provides a supporting force and can reduce the friction of transportation.

[0080] In an optional scheme of this embodiment, the synchronous welding device also includes a position sensor; the position sensor is arranged at the joint of the first workpiece 103 and the second workpiece 104, and is used to measure the positions of the first workpiece 103 and the second workpiece 104; when the first workpiece 103 and the second workpiece 104 move to a preset position, welding of the two can be started at this time. During the welding process, the first clamping mechanism 123 clamps the first workpiece 103, and the second clamping mechanism 124 clamps the second workpiece 104. When the winding machine pulls the first workpiece 103, the welding mechanism 101 can move synchronously.

[0081] Furthermore, when the welding process of the first workpiece 103 and the second workpiece 104 begins, the welding mechanism 101 continues to move toward the winding machine. Due to the limited length of the first slide rail 105, at the end of the welding process, the welding mechanism 101 needs to return to the initial position to weld the second workpiece 104 and the next third workpiece, and so on.

[0082] Therefore, in an optional solution of this embodiment, the synchronous welding device also includes a main transmission mechanism 130, which provides power for the movement of the first slide 106 along the first slide rail 105. Specifically, the power direction can be in the direction close to the winder. At this time, it is necessary to keep the power of the main transmission mechanism 130 synchronized with the power of the winder; when the power direction is in the opposite direction, the welding mechanism 101 can be returned to the initial position.

[0083] The main transmission mechanism 130 includes an eighth driving device 131 and a main transmission assembly 132. The eighth driving device 131 can drive the first slide 106 to move along the first slide rail 105 through the main transmission assembly 132; specifically, the main transmission assembly 132 includes a main gear 133 and a main rack 134 that are meshingly connected. The relative position of the main rack 134 and the first slide rail 105 is fixed and spaced apart. The main gear 133 is connected to the driving end of the eighth driving device 131, and the eighth driving device 131 is installed on the first slide 106. When the eighth driving device 131 drives the main gear 133 to rotate, the main gear 133 moves along the main rack 134, and the first slide 106 can move along the first slide rail 105.

[0084] In the optional scheme of this embodiment, when the first slide 106 moves toward the winding machine, in order to prevent the power provided by the main transmission mechanism 130 from being out of sync with the winding machine, the main transmission mechanism 130 is required to not provide power. The main transmission mechanism 130 also includes a fourth guide rail assembly 135 and a ninth drive device 136; the fourth guide rail assembly 135 includes a fourth slide rail and a fourth slider, the fourth slide rail is installed on the first slide 106, and the guide direction of the fourth slide rail is the height direction of the first slide 106; the eighth drive device 131 is connected to the fourth slider, and the ninth drive device 136 drives the fourth slider to move relative to the fourth slide rail, so that the main gear 133 connected to the eighth drive device 131 is close to or away from the main rack 134. When the main gear 133 is disengaged from the main rack 134, the power chain is disconnected; when the main gear 133 is close to the main rack 134 and meshes with it, the power can be transmitted again to realize the function of retreating to the initial position. The above method can prevent excessive wear between the main gear 133 and the main rack 134.

[0085] In an optional scheme of this embodiment, the synchronous welding device also includes a base platform 137; the number of first slide rails 105 is at least two, and multiple first slide rails 105 are arranged at intervals and installed on the top surface of the base platform 137 to achieve more stable support for the first slide 106; specifically, the first slide 106 may include a platform body and multiple first sliders slidably arranged on the first slide rails 105.

[0086] A plurality of spaced-apart anchor adjustment wheels 138 are provided at the bottom of the base platform 137 to adjust the height and flatness of the base platform 137 .
