[0046] The present application provides a turnover device for turning over a part during a welding process of the part to change the welding mode of a to-be-welded part on the part from vertical welding mode to flat welding mode.

[0047] In this application, the part is taken as a frame for example. Of course, in other embodiments, the part can be any other to-be-welded workpiece.

[0048] The following detailed description of specific embodiments of the flipping device of this application is provided in conjunction with the accompanying drawings.

[0049] Figure 1 This is a three-dimensional structural diagram of the flipping device in this embodiment. Figure 2 for Figure 1 Side view of the flipping device along the AA direction. Figure 3 for Figure 1 Side view of the flipping device along the BB direction. Figure 4 This is a top view of the flipping device in this embodiment.

[0050] refer to Figures 1 to 4 The flipping device includes a conveying assembly and a flipping assembly. The conveying assembly is used to convey components. At least two mounting positions are formed on the conveying assembly and / or on its outer side, with all mounting positions spaced apart. The flipping assembly includes a flipping frame 21 and at least two flipping mechanisms 22, with one flipping mechanism 22 corresponding to each mounting position. Each flipping mechanism 22 includes a base 222 and a flipping frame 221, which is rotatably connected to the base 222. The flipping frame 21 is connected to the flipping frames 221 of all flipping mechanisms 22, and the flipping frame 21 is located on the outer side of the conveying assembly. The flipping frame 21 and all flipping frames 221 are located on the same plane and together form a bearing position for bearing components. All flipping frames 221 can jointly drive the flipping frame 21 and the components to rotate upward or downward.

[0051] In this application, components are conveyed via a conveying assembly, ensuring that the components are fully supported and positioned at the bearing location formed by the flipping frame 21 and the flipping box 221. Then, all flipping boxes 221 are rotated synchronously and in the same direction relative to their corresponding bases 222, causing the flipping frame 21 and the components to rotate upwards or downwards. This rotates the components until the areas to be welded are in a horizontally extended state, changing the welding method from vertical welding to horizontal welding. This facilitates horizontal welding of the components, ensuring the weld is free of defects such as porosity and cracks, thus guaranteeing the stability of the welded components. Furthermore, this method of flipping components avoids quality problems such as bending deformation of the frame, simplifies the component flipping operation, improves the efficiency of component flipping, and enhances the safety of the flipping operation.

[0052] Furthermore, during component flipping, the flipping frame 221 and flipping bracket 21 jointly support the component, resulting in a large contact area between the flipping frame 221 and flipping bracket 21 and the component, thus improving the stability of the component support. In addition, the design of the flipping bracket 21 being located outside the conveying assembly avoids interference from the conveying assembly on the rotation of the flipping bracket 21, ensuring the smooth rotation of the flipping bracket 21.

[0053] In the embodiment, at least two mounting positions are formed on the conveying assembly and / or outside of the conveying assembly.

[0062] Reference Figure 5Exemplarily, the top of the rack 11 is provided with a plurality of supporting plates 13, and one end of each roller shaft 122 is arranged with one supporting plate 13. Each supporting plate 13 is provided with a clamping groove for clamping and fixing the roller shaft 122. Specifically, the cross section of each roller shaft 122 at both ends is in the shape of a flat square, a triangle or any other shape except a circle, and the shape of the clamping groove is matched with the shape of the roller shaft 122, so that the clamping groove can be clamped and fixed with the roller shaft 122, and the roller shaft 122 can be kept in a stationary state relative to the supporting plate 13, so as to achieve the purpose of rotating the roller 121 relative to the roller shaft 122.

[0063] In other embodiments, the plurality of conveying rollers 12 can include first conveying rollers 12 and second conveying rollers 12, wherein the first conveying rollers 12 are arranged in the above-mentioned manner, that is, the roller 121 of the first conveying roller 12 is rotatably connected with the roller shaft 122, and the roller shaft 122 is fixedly connected with the rack 11 through the supporting plate 13.

[0064] Alternatively, all the plurality of conveying rollers 12 are arranged in the above-mentioned manner of the second conveying roller 12, and part of the conveying rollers 12 are driven to rotate by the power member.

[0066] Reference Figure 1 , Figure 6In the embodiment, the conveying assembly further comprises a base 14, and the frame 11 is arranged on the base 14 in a liftable manner. For example, the frame 11 is provided with a first mounting hole 113, the base 14 is provided with a second mounting hole 141, and a fastener is arranged in the first mounting hole 113 and the second mounting hole 141 to achieve detachable connection between the frame 11 and the base 14. At least one of the first mounting hole 113 and the second mounting hole 141 is a waist-shaped hole, the length of the waist-shaped hole extends in the vertical direction, and the fastener can move in the waist-shaped hole. In actual application, the connection strength between the frame 11 and the base 14 can be appropriately loosened or the fastener can be detached from the frame 11 and the base 14 by operating the fastener, so that the frame 11 can move relative to the base 14, and the position of the fastener in the waist-shaped hole is changed until the conveying roller 12 reaches a suitable height. Then, the frame 11 and the base 14 are connected and fixed by operating the fastener, so that the height position of the conveying roller 12 is fixed. In this way, the height of each frame 11 can be adjusted, and the conveying rollers 12 on each frame 11 can be ensured to be located on the same plane, so as to ensure the smoothness of conveying the parts by the conveying assembly.

[0067] Specifically, the base 14 is provided with a plurality of slide grooves opening upward, and the second mounting hole 141 is communicated with the slide groove. Each stand 112 is inserted into the slide groove of the corresponding base 14 in a sliding manner.

[0070] In the embodiment, the turnover assembly comprises a turnover frame 21 and at least two turnover mechanisms 22. Each mounting position is provided with a turnover mechanism 22.

[0071] Figure 7 For Figure 1 The enlarged structure schematic view at E.

[0072] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7Each of the turnover mechanisms 22 comprises a base 222 and a turnover frame 221 rotatably connected with the base 222. The turnover frame 21 is connected with the turnover frames 221 of all the turnover mechanisms 22 and is located outside the conveying assembly. The turnover frame 21 and the turnover frames 221 are located in the same plane and jointly form a carrying position for carrying the component.

[0073] The turnover frames 221 can synchronously and uniformly rotate to drive the turnover frame 21 and the component to rotate upward or downward relative to the base 222, so as to switch the carrying position between the first state and the second state. When the carrying position is in the first state, the upper surfaces of the turnover frames 221 and the turnover frame 21 are horizontally extended. The turnover frames 221 are turned upward to change the carrying position to the second state. It should be noted that when the conveying assembly is used to convey the component, the carrying position is in the first state, and the conveying roller 12 can be lifted upward so that the top portion is above the carrying position, to avoid the interference of the turnover frames 221 and the turnover frame 21 with the movement of the component, thereby ensuring the smooth movement of the component.

[0074] In the embodiment, the turnover frame 21 comprises a longitudinal beam 211 and two lateral beams 212. The longitudinal beam 211 extends in the longitudinal direction and is fixed to the first ends of all the turnover frames 221 and is located outside the conveying assembly in the transverse direction. The two lateral beams 212 are arranged at the longitudinal ends of the longitudinal beam 211 and are located outside the conveying assembly in the longitudinal direction.

[0075] With reference to Figure 2 , Figure 3 and Figure 7 , for example, in each of the turnover mechanisms 22, the turnover frame 221 and the base 222 are vertically spaced. The turnover mechanism 22 further comprises a turnover piece 223 arranged between the first end bottom of the turnover frame 221 and the first end top of the base 222, and the turnover piece 223 is used to rotatably connect the turnover frame 221 and the base 222. Specifically, the turnover piece 223 comprises an upper turnover seat 2231, a lower turnover seat 2232 and a turnover shaft 2233. The upper turnover seat 2231 is connected to the first end bottom of the turnover frame 221, and the lower turnover seat 2232 is connected to the first end top of the base 222. The upper turnover seat 2231 is provided with a receiving groove opening downward, and the receiving groove is used to accommodate at least part of the lower turnover seat 2232. The turnover shaft 2233 penetrates the upper turnover seat 2231 and the lower turnover seat 2232, and the upper turnover seat 2231 and the lower turnover seat 2232 are rotatably connected through the turnover shaft 2233. The first end of the turnover frame 221 refers to one end of the turnover frame 221 in the transverse direction, the first end of the base 222 refers to one end of the base 222 in the transverse direction, and the first end of the turnover frame 221 and the first end of the base 222 are located on the same side.

[0076] With reference toFigure 1 and Figure 7 Optionally, the overturning mechanism 22 further comprises a driving member 224, which is rotatably connected to the base 222 and the overturning frame 221, and is used to drive the overturning frame 221 to rotate relative to the base 222, so as to improve the automation degree of the overturning device, facilitate the operation, reduce the labor intensity, and further improve the operation safety.

[0077] Specifically, the driving member 224 comprises a driving body 2241 and an output shaft 2242. The driving body 2241 is drivingly connected to the output shaft 2242, and is used to drive the output shaft 2242 to extend or retract. The driving body 2241 is rotatably connected to the second end of the base 222, so that the driving body 2241 can rotate relative to the base 222. The output shaft 2242 is rotatably connected to the first end of the overturning frame 221, so that the output shaft 2242 can rotate relative to the overturning frame 221. Since the connection between the output shaft 2242 and the overturning frame 221 and the connection between the driving body 2241 and the base 222 remain unchanged, with the extension or retraction of the output shaft 2242, the output shaft 2242 rotates relative to the overturning frame 221, and the driving body 2241 rotates relative to the base 222, so that the driving member 224 can adapt to the change in length, and at the same time, the overturning frame 221 can rotate relative to the base 222 to adapt to the change in length of the driving member 224.

[0078] Specifically, the driving member 224 comprises a driving body 2241 and an output shaft 2242. The driving body 2241 is drivingly connected to the output shaft 2242, and is used to drive the output shaft 2242 to extend or retract. The driving body 2241 is rotatably connected to the second end of the base 222, so that the driving body 2241 can rotate relative to the base 222. The output shaft 2242 is rotatably connected to the first end of the overturning frame 221, so that the output shaft 2242 can rotate relative to the overturning frame 221. Since the connection between the output shaft 2242 and the overturning frame 221 and the connection between the driving body 2241 and the base 222 remain unchanged, with the extension or retraction of the output shaft 2242, the output shaft 2242 rotates relative to the overturning frame 221, and the driving body 2241 rotates relative to the base 222, so that the driving member 224 can adapt to the change in length, and at the same time, the overturning frame 221 can rotate relative to the base 222 to adapt to the change in length of the driving member 224.

[0079] Optionally, the overturning frame 221 is provided with a first slot body with an opening downward, and the end of the output shaft 2242 extends into the first slot body and passes through the output shaft 2242 and the overturning frame 221 in the longitudinal direction through a first connecting shaft 241, so as to realize the rotatable connection between the output shaft 2242 and the overturning frame 221. The base 222 is provided with a second slot body with an opening upward, and the end of the driving body 2241 extends into the second slot body and passes through the driving body 2241 and the base 222 in the longitudinal direction through a second connecting shaft 242, so as to realize the rotatable connection between the driving body 2241 and the base 222. In the above manner, the connection between the driving member 224 and the overturning frame 221 and the base 222 can reduce the height of the bearing position to some extent, so as to facilitate the welding operation of the components placed on the bearing position, and at the same time, the structure of the overturning mechanism 22 is more compact.

[0080] The overturning frame 221 is further provided with a mounting slot with an opening upward. Specifically, in the embodiment, the overturning frame 221 has an upper and lower through rectangular frame structure.

[0081] In the embodiment, the structure of the base 222 can be the same as that of the overturning frame 221.

[0082] Optionally, the second end bottom of the turnover frame 221 or the second end top of the base 222 is provided with a support column 25, which is used for supporting the turnover frame 221 when the carrying position is in the first state, so as to ensure the stability of the turnover frame 221 and the turnover frame 21. Wherein, the second end of the turnover frame 221 refers to the end opposite to the first end of the turnover frame 221 along the transverse direction, and the same applies hereinafter.

[0083] The turnover assembly further comprises a plurality of connecting seats 26, at least one connecting seat 26 is connected to the bottom of the base 222 of each turnover mechanism 22, the connecting seat 26 outwardly exceeds the opposite sides of the base 222, the connecting seat 26 is provided with a connecting hole 261 for the connecting member to pass through, and the connecting seat 26 can be fixed to the support surface through the connecting member, so as to fix the turnover mechanism 22 to the support surface. Wherein, the connecting member can be a bolt, a screw or the like.

[0102] The second limiting member 32 is moved away from the first limiting member 31 to expand the interval between the first limiting member 31 and the second limiting member 32. Then, the preliminarily fixed parts are conveyed by the conveying rollers 12 of the conveying assembly until the parts are completely located on the conveying assembly and correspondingly located at the bearing position and the limiting position.

[0103] The second limiting member 32 is moved to abut against the end of the part and push the part until the part abuts against the first limiting member 31, so as to fix the part.

[0104] The driving members 224 of the turnover mechanisms 22 are synchronously started to make the output shafts 2242 of the driving members 224 extend under the action of the driving bodies 2241, and since the positions of the connecting places of the output shafts 2242 with the turnover frames 221 and the connecting places of the driving bodies 2241 with the bases 222 are fixed, the output shafts 2242 can push the turnover frames 221 to rotate around the turnover shafts 2233 in the process of the extension of the output shafts 2242, and drive the turnover frames 21 and the parts to rotate until the welding positions on the parts are in the horizontal extension state, and then the welding positions are horizontally welded.

[0105] From the above technical solution, the utility model has at least the following advantages and positive effects:

[0106] In the application, the parts are conveyed by the conveying assembly so that the parts are completely supported by the conveying assembly and are located at the bearing positions formed by the turnover frames and the turnover frames, and then all the turnover frames are synchronously and uniformly rotated relative to the corresponding bases to drive the turnover frames and the parts to rotate upward or downward to rotate the parts to make the welding positions on the parts in the horizontal extension state, so that the welding mode of the welding positions on the parts is changed from the vertical welding mode to the horizontal welding mode, which facilitates the horizontal welding of the welding positions on the parts to ensure that the welding seams are free of defects such as pores and cracks to ensure the stability of the welded parts. In addition, the turnover of the parts in the above-mentioned mode can avoid the bending deformation and other quality problems of the frame, simplify the operation of the turnover of the parts, improve the turnover efficiency of the parts, and improve the safety of the turnover operation.
