Description

Technical Field

[0001] This utility model relates to the technical field of welding fixtures, and in particular to a door panel welding flipping device. Background Technology

[0002] In the field of metal door panel welding, traditional processes generally employ manual operation to flip and position the door panels. Specifically, when performing multi-sided welding operations, operators need to manually adjust the posture of the door panel to expose the area to be welded.

[0003] However, existing technologies have the following shortcomings: First, operators need to repeatedly move heavy metal door panels to adjust the welding angle. Due to the weight of the metal door panels and the fact that they need to be flipped at least four times during the entire welding process, the workload for workers is high. Second, although the surface of the metal door panels is smooth, there are obvious burrs at the joints between the panels, posing a risk of slippage and scratches during manual flipping. Third, operators find it difficult to precisely control the flipping angle, which can easily lead to defects such as undercut and incomplete fusion in the weld due to angle deviation. Finally, manual flipping cannot meet the needs of automated welding. Therefore, to address the above shortcomings, the door panel welding flipping device of this application is proposed. Utility Model Content

[0027] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0028] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0031] like Figures 1 to 3 As shown, a door panel welding flipping device 10 includes a base 110 and a flipping assembly 200. Four load-bearing wheels 120 are symmetrically arranged on the base 110, and every two load-bearing wheels 120 form a load-bearing wheel pair. The flipping assembly 200 includes a support frame 210 and two rings 220. The two ends of the support frame 210 are respectively connected to the two rings 220. A clamping groove 211 is opened in the support frame 210, which passes through the two rings 220. The clamping groove 211 is used to insert the door panel. The two rings 220 respectively form a rolling engagement with the two load-bearing wheel pairs.

[0032] It should be noted that the support frame 210 is welded and fixed to two rings 220, with the two rings 220 located at both ends of the support frame 210. A clamping groove 211 is formed within the support frame 210, and the clamping groove 211 passes through both rings 220. Each pair of load-bearing wheels 120 jointly supports one ring 220. Thus, when the door panel is inserted into the clamping groove 211, applying external force to either ring 220 causes the flipping assembly 200 to flip the metal door panel to any angle. This replaces manual flipping by workers, preventing the door panel from scratching them and reducing worker workload. Furthermore, by connecting the rings 220 to a drive source such as a motor, automatic welding of the door panel is easily achieved.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, a limiting groove 121 is provided circumferentially on the outer side wall of the load-bearing wheel 120, and the ring 220 is adapted to be accommodated in the limiting groove 121.

[0034] It should be noted that when the ring 220 is embedded in the limiting groove 121, the sidewall of the limiting groove 121 forms a radial limit on the ring 220, restricting its axial displacement. The sidewall of the limiting groove 121 constrains the radial displacement of the ring 220, preventing the ring 220 from detaching from the load-bearing wheelset during the rolling process. The limiting groove 121 can be designed with a V-shaped cross-section, and correspondingly, the outer sidewall of the ring 220 is also designed with a V-shaped cross-section, allowing the ring 220 to automatically correct its center position and rotate stably during rolling.

[0035] like Figures 1 to 3 As shown, in one embodiment, the door panel welding and flipping device 10 further includes a braking component 300. The braking component 300 includes an elastic component 310, a handle 320, and a friction block 330. One end of the handle 320 is rotatably mounted on the base 110, and the friction block 330 is mounted on the handle 320. Both ends of the elastic component 310 are connected to the handle 320 and the base 110, respectively. The elastic component 310 is used to drive the handle 320 to drive the friction block 330 to abut against one of the load-bearing wheels 120.

[0036] It should be noted that the handle 320 is hinged to the base 110 via a pin, and its plane of rotation is perpendicular to the axis of the load-bearing wheel 120. The elastic element 310 connects the handle 320 and the base 110 at both ends, and under normal conditions, the elastic tension keeps the friction block 330 in contact with the load-bearing wheel 120. The friction block 330 is made of copper-based powder metallurgy material and is detachably installed in the middle of the handle 320 via bolts. Its inner arc surface curvature matches the outer circle of the load-bearing wheel 120. When the handle 320 is pressed outward, the elastic element 310 is stretched, and the friction block 330 moves away from the load-bearing wheel 120, allowing the ring 220 to roll freely on the load-bearing wheel 120. Thus, the friction block 330 locks the load-bearing wheel 120, allowing the metal door panel to be welded in a stable and stationary environment. When it needs to be flipped, simply pull the handle 320 to move the load-bearing wheel 120 away. In one embodiment, the surface of the friction block 330 is coated with a 0.2 mm thick silicon carbide coating to ensure that the friction block 330 maintains a stable coefficient of friction in the environment of welding spatter.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment, the support frame 210 includes two inner frames 212, both ends of which are connected to two rings 220 respectively, and a clamping groove 211 is formed between the two inner frames 212.

[0038] It should be noted that the support frame 210 consists of two parallel inner frames 212. The inner frames 212 are made of square tubing, and their ends are fixed to the two rings 220 by welding or bolting. The distance between the clamping grooves 211 between the two inner frames 212 is between 50mm and 300mm.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the support frame 210 further includes two outer frames 213, each of which is connected to two rings 220, and the two outer frames 213 are located on the side of the two inner frames 212 away from the clamping groove 211.

[0040] It should be noted that the support frame 210 consists of two inner frames 212 and two outer frames 213. The inner frames 212 and outer frames 213 are arranged in parallel and are connected to the two rings 220 by welding. The two outer frames 213 are located on the outer side of the inner frames 212 away from the clamping groove 211. The double outer frame structure effectively improves the overall bending stiffness of the support frame 210, thus making it suitable for welding thin decorative door panels and heavy-duty security door panels. Moreover, the double-layer structure of the outer frames 213 and inner frames 212 can achieve a double insurance result. Even if a single layer of the frame (outer frame 213 or inner frame 212) is damaged, it can still maintain 50% of the rated load capacity without directly collapsing, thus providing better safety and avoiding direct damage to the door panel located in the clamping groove 211. In one embodiment, the outer frames 213, inner frames 212, and rings 220 are welded together, thereby ensuring that the outer frames 213, inner frames 212, and rings 220 maintain sufficient structural strength.

[0041] like Figures 1 to 3 As shown, in one embodiment, a plurality of clamping members 230 are screwed onto the outer frame 213. The clamping members 230 are used to pass through the inner frame 212 and extend into the clamping groove 211 when subjected to force and rotation. The clamping members 230 include a screw 231 and a clamping block 232. The screw 231 is screwed onto the outer frame 213. The clamping block 232 is rotatably disposed at one end of the screw 231 near the inner frame 212. When the screw 231 is subjected to force and rotation, the clamping block 232 passes through the inner frame 212 and extends into the clamping groove 211.

[0042] It should be noted that the screw 231 uses a trapezoidal thread, which mates with the threaded hole on the outer frame 213. The pressure block 232 is mounted on the end of the screw 231 via a needle roller bearing and can rotate freely 360° around its axis. The inner frame 212 has clearance structures at corresponding positions of each clamping component 230. After penetrating the inner frame 212, the pressure block 232 directly contacts the side wall of the door panel, and the rotation structure of the pressure block 232 can automatically compensate for the placement angle of the door panel. By controlling the rotation angle of the screw 231, precise adjustment of the pressure on the door panel can be achieved. Furthermore, in one embodiment, a pressure sensor is installed between the screw 231 and the pressure block 232, thereby accurately detecting the clamping force on the door panel, ensuring that the door panel is reliably clamped, while preventing it from being crushed.

[0043] like Figure 4 As shown, in one embodiment, a silicone layer 233 is provided on the side of the pressure block 232 away from the screw 231.

[0044] It should be noted that the silicone layer 233 has a thickness of 5±0.2mm and is made of high-temperature vulcanized silicone rubber. It is integrally formed with the pressure block 232 through an in-mold molding process. In one embodiment, the surface of the silicone layer 233 is processed with a 1mm deep cross-shaped pattern. This ensures stable pressure on the door panel while preventing damage to the door panel.

[0045] like Figure 4 As shown, in one embodiment, a crossbar 234 is provided on the end of the screw 231 away from the pressure block 232. In this way, the crossbar 234 facilitates the application of torque to the screw 231.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
