Description

Technical Field

[0001] This utility model relates to the technical field of welding auxiliary tooling, and in particular to a base frame tilting device. Background Technology

[0002] Metal frames, as key load-bearing components in industrial equipment, large machinery, and building structures, typically require continuous welding on both sides to meet structural strength requirements.

[0003] Currently, when welding the base frame, lifting equipment is used for auxiliary hoisting to weld the front and back sides of the base frame. Tilting the base frame requires reserved space for operation, occupying too much production floor space. Secondly, using lifting equipment requires manual operation by workers, which is inherently dangerous, and the equipment is slow and inefficient. Therefore, traditional metal base frame welding and tilting methods can no longer meet the safety, efficiency, and precision requirements of modern manufacturing. To solve these problems, the base frame tilting device proposed in this application is presented. Utility Model Content

Both flipping drives are mounted on the slide block, and their output shafts are rotatably connected to the two flipping arms respectively. The flipping drives drive the flipping arms to rotate to a vertical or horizontal position.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] like Figures 1 to 3 As shown, a base frame tilting device 10 includes a base plate 100 and two tilting assemblies 200. A plurality of rollers 300 are rotatably arranged on the base plate 100 at intervals along a straight line. The two tilting assemblies 200 are spaced apart on the base plate 100. Each tilting assembly 200 includes a slide block 210, a sliding drive member 220, two tilting arms 230, and two tilting drive members 240. The slide block 210 is slidably disposed on the base plate 100 along the axial direction of the rollers 300, and the sliding drive members 220 are disposed on the base plate 100. The output shaft of the sliding drive 220 is connected to the slide block 210. The sliding drive 220 is used to drive the slide block 210 to slide back and forth between the two ends of the roller 300. One end of each of the two flipping arms 230 is rotatably mounted on the slide block 210. Both flipping drives 240 are mounted on the slide block 210. The output shafts of the two flipping drives 240 are rotatably connected to the two flipping arms 230 respectively. The flipping drives 240 are used to drive the flipping arms 230 to rotate to a vertical or horizontal state.

[0033] It should be noted that the base plate 100 can be set as a specific ground surface or a single independent iron plate, depending on the installation site, as long as it ensures that each roller 300 can be stably rotated and installed. The rollers 300 are rotated and installed via support frames to ensure a certain height between the rollers 300 and the base plate 100. The rollers 300 are arranged at intervals along a straight line, and the axes of each roller 300 are on the same plane and parallel to each other. Thus, the rollers 300 can collectively support and move the metal base frame. Furthermore, the sliding drive 220 drives the slide block 210 to reciprocate along both ends of the rollers 300. For example, the sliding drive 220 is a screw module driven by a motor, wherein the screw module is screwed to the slide block 210, thus allowing the slide block 210 to slide stably on the base plate 100. Furthermore, each flip arm 230 is driven by a flip drive 240, so that one end of the flip arm 230 can be flipped relative to the slide block 210 to change from a horizontal state to a vertical state. For ease of description, the two tilting arms 230 are defined as the first arm and the second arm, respectively. The two ends of the roller 300 on the same side as the first and second arms are defined as the first end and the second end, respectively. When the slide 210 is located at the first end of the roller 300, the first arm is in a vertical state and the second arm is in a horizontal state. When the second arm rotates to become vertical, it can drive the metal base frame supported by each roller 300 to change from a horizontal state to a vertical state and abut against the first arm. During the tilting process of the metal base frame, the slide 210 slides on the base plate 100 to move from the first end of the roller 300 to the second end. Then the first arm rotates to change from a vertical state to a horizontal state, so that the metal base frame follows the first arm to change from a vertical state to a horizontal state and is finally supported by each roller 300. In this way, the automatic tilting operation of the metal base frame is realized. Compared with the existing method of using lifting equipment for hoisting and tilting, this application integrates automatic feeding and tilting operation of the metal base frame, which does not require operation on an open ground and has high safety and high operation efficiency.

[0034] like Figure 4 As shown, in one embodiment, when the tilting arm 230 is in a horizontal state, the tilting arm 230 is lower than the highest point of the outer side wall of the roller 300. Thus, when the tilting arm 230 is in a horizontal state, the tilting arm 230 is located below the roller 300, avoiding obstruction of the metal base frame, and allowing the metal base frame to be smoothly moved by each roller 300.

[0035] like Figures 1 to 4 As shown, in one embodiment, a material support block 250 is provided on the tilting arm 230. When both tilting arms 230 are in a vertical state, the two material support blocks 250 jointly support the metal base frame.

[0036] It should be noted that, in order to ensure that the metal base is always higher than each roller 300 when the tilting arm 230 changes from a horizontal state to a vertical state, so as to ensure that the slide block 210 can drive the metal base to slide along the axial direction of the roller 300, a material support block 250 is provided on the opposite side of the two tilting arms 230.

[0037] like Figure 4 As shown, in one embodiment, when the tilting arm 230 is in a vertical state, the material support block 250 is higher than the highest point of the outer side wall of the roller 300.

[0038] It should be noted that when the tilting arm 230 changes from a horizontal state to a vertical state, the metal base frame will slide along the tilting arm 230 and be supported by the material support block 250. In this way, the metal base frame is ensured to be higher than each roller 300, so that it can be smoothly driven by the slide block 210 to slide.

[0039] In one embodiment, the material support block 250 has an L-shaped structure. Thus, the material support block 250 can engage with the side of the metal base frame, thereby ensuring proper engagement and positioning of the metal base frame and improving its stability.

[0040] like Figure 4 As shown, in one embodiment, a sensor 260 is provided on the slide 210, and a baffle 270 is provided on the flip arm 230. When the flip arm 230 is in a horizontal state, the baffle 270 is brought close to the sensor 260.

[0041] It should be noted that in order to ensure that the tilting arm 230 is tilted to a horizontal position, a sensor 260 is provided to detect the baffle 270. For example, the sensor 260 is a metal sensor, and the baffle 270 is a metal sheet structure welded and fixed to the tilting arm 230.

[0042] In one embodiment, the tilting drive 240 is a hydraulic cylinder or a pneumatic cylinder. This ensures that the tilting arm 230 can rotate stably relative to the slide 210.

[0043] like Figure 1 As shown, in one embodiment, the flipping assembly 200 further includes a slide rail 280, which is disposed on the base plate 100, and the slide block 210 is slidably connected to the slide rail 280.

[0044] It should be noted that the slide rail 280 extends from one end of the roller 300 to the other end, so that the slide block 210 can slide stably on the slide rail 280.

[0045] like Figure 5 As shown, in one embodiment, the slide rail 280 is made of I-beams, and the slide block 210 is provided with a plurality of rollers 290, each of which is tactilely connected to the slide rail 280.

[0046] It should be noted that two grooves are provided on the I-beam, and the roller 290 is located in the groove. This ensures that the slide block 210 slides stably along the length of the slide rail 280 and avoids overturning.

[0047] In one embodiment, each roller 300 is divided into two groups, with a gap between the two groups of rollers 300. Thus, the two groups of rollers 300 are distributed in parallel to each other, and the two groups of rollers 300 jointly support the metal base frame. For example, the distance between the two groups of rollers 300 is adjustable, so it can be applied to the transfer and flipping operation of metal base frames of any width.

[0048] 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.
