Description

Technical Field

[0001] This utility model application relates to the technical field of casting hangers, specifically to a casting hanger. Background Technology

[0002] In the casting production and subsequent processing, casting racks serve as key transfer equipment connecting various processes, undertaking the core functions of suspending, transferring, and temporarily storing castings. Their performance directly affects production efficiency, transfer safety, and equipment adaptability. With the diversification of manufacturing demands for castings, the size differences of castings are becoming increasingly significant. From precision parts a few centimeters in size to large structural components several meters in size, all require transfer via racks, which places stringent requirements on the racks' adaptability to various scenarios.

[0003] Patent CN222157564U discloses a turnover device for precision casting with shells. Its working principle is as follows: by moving a regular square prism horizontally to disengage it from the limiting insertion hole, rotating the regular square prism drives the suspension rod to switch postures. When the suspension rod is horizontally extended, the shelled casting can be suspended. When the suspension rod is vertically rotated and re-inserted into the limiting insertion hole, it can be hidden in the connecting frame to avoid interference. Based on this design, the device can realize three usage states: the suspension rod is fully hidden, the upper layer is extended and the lower layer is hidden, and both layers are fully extended, so as to adapt to the suspension needs of castings of different sizes.

[0004] Although the above solution meets the suspension requirements of castings of different sizes, the suspension rod on the square prism in this solution has a limited length. When suspending larger castings or castings with protruding structures, the distance between the edge of the casting and the first and second connecting plates is too close. Even slight shaking during transportation can easily cause the casting to collide with the connecting plates, resulting in damage to the outer shell of the casting and deformation of the internal casting. Especially for precision castings, the quality damage caused by the collision directly affects the product qualification rate. Utility Model Content

[0005] To address the aforementioned issues, a casting hanger is provided, which, by incorporating a position switching mechanism, can meet the hanging requirements for castings of various sizes, significantly improving the hanger's versatility and adaptability.

[0006] To address the problems of existing technologies, this utility model application provides a casting hanger, including a mobile frame. The frame includes two vertical beams, with two suspension structures arranged vertically between the two vertical beams. The upper end of the mobile frame is provided with a position switching mechanism for switching the two vertically arranged suspension structures to a horizontally arranged left-right configuration. The position switching mechanism includes a main shaft, two mounting arms, a rotating mechanism, and a support mechanism.

The two mounting arms are respectively located at the two ends of the main shaft and between the two vertical beams. The middle part of the mounting arms is connected to the main shaft, and the two ends of the suspension structures are respectively connected to the ends of the two mounting arms. The rotating mechanism is located at one end of the main shaft and includes a turntable and a first fixing structure. The middle part of the turntable is connected to the main shaft, and the first fixing structure is located on one side of the turntable and is used to fix the turntable.

[0008] Preferably, the first fixing component includes a first threaded sleeve and a first fixing rod; the first threaded sleeve is mounted on the bracket, and the axis of the first threaded sleeve is perpendicular to the surface of the turntable; the middle part of the first fixing rod is an external threaded part, which is threadedly connected to the first threaded sleeve.

[0009] Preferably, the support mechanism includes two support arms and a synchronous drive structure; the two support arms are symmetrically arranged about the vertical beam, and one end of each support arm is provided with a rotating shaft, which is connected to the vertical beam through a bearing seat; the synchronous drive structure is arranged between the two support arms and is connected to the two rotating shafts, and drives the two rotating shafts to rotate in opposite directions.

[0010] Preferably, the synchronous drive structure includes a moving block and two gear and rack transmission assemblies; the moving block is disposed on the vertical beam and can move up and down in the vertical direction along the vertical beam; the two gear and rack transmission assemblies are respectively disposed at both ends of the moving block, and the gear and rack transmission assemblies convert the vertical movement of the moving block into the rotational movement of the shaft.

[0011] Preferably, the synchronous drive structure further includes a guide structure, which is used to limit the movement direction and posture of the moving block.

[0012] Preferably, the synchronous drive structure also includes a linkage rod, with connecting shafts at both ends of the linkage rod, and the two connecting shafts are respectively connected to the moving block and the turntable.

[0013] Preferably, the support mechanism further includes two second fixing structures, which are respectively disposed on the two support arms. The second fixing structures are used to fix the support arms and the mounting arms.

[0014] The advantages of this utility model application compared to the prior art are:

[0015] This utility model application provides a position switching mechanism. The first fixed structure in the position switching mechanism releases the fixation of the turntable. Subsequently, the turntable drives the main shaft, mounting arm and suspension structure to rotate 90 degrees synchronously, realizing the switching of the suspension structure from vertical arrangement to horizontal left and right arrangement. Then, the first fixed structure re-fixes the turntable, restricting its rotational freedom to ensure the stability of the suspension structure position. At the same time, the support mechanism provides upward support force to both ends of the mounting arm to counteract the downward force of the mounting arm and casting, ensuring the horizontal balance of the mounting arm. This meets the suspension requirements of various castings of different sizes and significantly improves the versatility and adaptability of the hanger. Attached Figure Description

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 8 As shown: A casting hanger includes a mobile frame 1, which includes two vertical beams 11. Two suspension structures 2 are arranged vertically between the two vertical beams 11. The upper end of the mobile frame 1 is provided with a position switching mechanism for switching the two vertically arranged suspension structures 2 to a horizontally arranged position. The position switching mechanism includes a main shaft 3, two mounting arms 4, a rotating mechanism 5, and a support mechanism 6. The two ends of the main shaft 3 are respectively connected to the two vertical beams 11 via bearings. The two mounting arms 4 are respectively located at both ends of the main shaft 3 and between the two vertical beams 11. The middle part of the mounting arms 4 is connected to the main shaft 3, and the two ends of the suspension structures 2 are respectively connected to the ends of the two mounting arms 4. The rotating mechanism 5 is located at one end of the main shaft 3 and includes a turntable 51 and a first fixing structure 52. The middle part of the turntable 51 is connected to the main shaft 3, and the first fixing structure 52 is located on one side of the turntable 51 and is used to fix the turntable 51. The support mechanism 6 is located on the vertical beams 11 and is used to support the two horizontally arranged suspension structures 2.

[0027] When suspending smaller castings, the two suspension structures 2 are arranged vertically between the two vertical beams 11. Because the smaller castings have a smaller volume and occupy less space, in this arrangement, multiple smaller castings can be suspended on both sides of the two suspension structures 2 without collision or interference between adjacent castings. This achieves the goal of suspending a large number of smaller castings at once, meeting the needs of batch suspension, transport, or processing of small castings. However, when suspending larger or longer castings, due to their large volume and space occupation, using the vertically arranged suspension structures 2 would cause collisions between castings or between castings and the suspension structures 2. Therefore, the arrangement of the two suspension structures 2 needs to be changed. First, the first fixing structure 52 releases its fixing effect on the turntable 51, and the turntable 51 rotates 90 degrees around the axis of the main shaft 3. The two mounting arms 4, fixedly connected to the main shaft 3, also rotate 90 degrees synchronously around the axis of the main shaft 3. The two suspension structures 2 rotate together, ultimately causing the two suspension structures 2, originally arranged vertically, to rotate to a horizontal position between the two vertical beams 11. In the horizontally aligned left-right configuration, the horizontal distance between the two suspension structures 2 reaches its maximum, providing ample suspension space for larger and longer castings. Then, the first fixing structure 52 re-fixes the turntable 51, while the support mechanism 6 provides upward support to both ends of the mounting arm 4. This effectively counteracts the weight of the mounting arm 4 and the suspension structure 2 itself, as well as the downward force generated by the subsequent suspension of the casting, ensuring that the mounting arm 4 remains horizontally balanced. At this point, larger or longer castings can be suspended on the two horizontally aligned left-right suspension structures 2. Each casting has independent and sufficient space, preventing collisions between castings or between castings and the suspension structure 2 even if the castings sway during transport. This ensures the safety and stability of the suspension process for larger castings. Through the design of the position switching mechanism, the two suspension structures 2 can be switched between vertical and horizontal alignments depending on the size of the casting, thus meeting the suspension requirements for various casting sizes and significantly improving the versatility and adaptability of the hanger.

[0028] Reference Figure 2 and Figure 3 As shown: The first fixing structure 52 includes a bracket 521 and a first fixing component 522; the bracket 521 is mounted on the vertical beam 11 and one end covers the turntable 51. Two fixing holes 511 are opened on the turntable 51, and the line connecting the two fixing holes 511 and the center of the turntable 51 is perpendicular; the first fixing component 522 is disposed at one end of the bracket 521 and is used to mate with the fixing holes 511 on the turntable 51.

[0029] When the two suspension bracket structures 2 of the casting hanger are arranged vertically, the first fixing component 522 installed on the bracket 521 mates with one of the fixing holes 511 on the turntable 51, and the turntable 51 cannot rotate around the axis of the main shaft 3. When it is necessary to switch the suspension bracket structure 2 from vertical arrangement to horizontal left-right arrangement, the first fixing component 522 is pulled out from the currently mated fixing hole 511, releasing the mechanical limit on the turntable 51. At this time, the turntable 51 can rotate freely around the axis of the main shaft 3. The operator pushes the turntable 51 to rotate 90 degrees counterclockwise around the axis of the main shaft 3, and the turntable 522, which was not originally mated with the first fixing component 522, rotates freely around the axis of the main shaft 3. The second fixing hole 511 of the 2-connection will rotate to the position corresponding to the first fixing component 522. The first fixing component 522 is inserted into the second fixing hole 511, and a mechanical limit is formed again. The rotational freedom of the turntable 51 is restricted again, and it cannot continue to rotate around the axis of the main shaft 3. This ensures that the main shaft 3, the mounting arm 4 and the suspension structure 2 are stably kept in a horizontally aligned position. Through the cooperative design of the bracket 521, the first fixing component 522 and the two vertically distributed fixing holes 511 on the turntable 51, the fixing and release of the turntable 51 can be completed quickly, thereby realizing the rapid switching of the position of the suspension structure 2.

[0030] Reference Figure 3 and Figure 4 As shown: The first fixing component 522 includes a first threaded sleeve 5221 and a first fixing rod 5222; the first threaded sleeve 5221 is mounted on the bracket 521, and the axis of the first threaded sleeve 5221 is perpendicular to the surface of the turntable 51; the middle part of the first fixing rod 5222 is an external threaded part, which is threadedly connected to the first threaded sleeve 5221.

[0031] When the two suspension structures 2 of the casting bracket are arranged vertically, one end of the first fixing rod 5222 is inserted into the fixing hole 511 of the turntable 51. When it is necessary to switch the suspension structure 2 from vertical arrangement to horizontal left-right arrangement, the first fixing rod 5222 is rotated. During the rotation, the threaded transmission converts the rotational motion into linear motion, driving the first fixing rod 5222 to gradually move away from the turntable 51 along its own axis until the first fixing rod 5222 separates from the first fixing hole 511. After the turntable 51 rotates 90 degrees, one end of the first fixing rod 5222 corresponds to the second fixing hole 511. The first fixing rod 5222 is rotated in the opposite direction. During the rotation, the first fixing rod 5222 moves closer to the turntable 51 along its own axis and finally inserts into the fixing hole 511. Through the threaded connection structure between the first threaded sleeve 5221 and the first fixing rod 5222, the first fixing rod 5222 is effectively prevented from moving along the axis by itself, thus avoiding accidental separation from the fixing hole 511 of the turntable 51.

[0032] Reference Figure 1 and Figure 5As shown: The support mechanism 6 includes two support arms 61 and a synchronous drive structure 62; the two support arms 61 are symmetrically arranged about the vertical beam 11, and one end of each support arm 61 is provided with a rotating shaft 611, which is connected to the vertical beam 11 through a bearing seat; the synchronous drive structure 62 is arranged between the two support arms 61 and is connected to the two rotating shafts 611, and drives the two rotating shafts 611 to rotate in opposite directions.

[0033] When the two suspension structures 2 are arranged horizontally, the castings suspended on the suspension structures 2 are far from the main shaft 3 in the middle of the mounting arm 4. This causes the lever arm between the stress point and the support point (main shaft 3) of the mounting arm 4 to be significantly extended. The mounting arm 4 is prone to bending deformation under the weight of the castings. Therefore, two support arms 61 and a synchronous drive structure 62 are provided. When the two suspension structures 2 are arranged vertically, the two support arms 61 are close to the vertical beam 11, meaning the angle between the support arms 61 and the vertical beam 11 is small. When it is necessary to switch the positions of the two suspension structures 2, the synchronous drive structure... The structure 62 drives two rotating shafts 611 to rotate in opposite directions. The two rotating shafts 611 respectively drive two support arms 61 to rotate. The included angle between the two support arms 61 gradually increases until the support arm 61 contacts the part of the mounting arm 4 near the suspension frame structure 2. Through the contact point between the support arm 61 and the mounting arm 4, part of the weight of the casting on the mounting arm 4 is transferred to the vertical beam 11. This is equivalent to adding an auxiliary support point near the force-bearing end of the mounting arm 4, shortening the actual force arm of the mounting arm 4, thereby effectively counteracting the bending moment generated by the weight of the casting on the mounting arm 4 and preventing the mounting arm 4 from bending and deforming.

[0034] Reference Figure 5 and Figure 6 As shown: The synchronous drive structure 62 includes a moving block 621 and two gear and rack transmission groups 622; the moving block 621 is disposed on the vertical beam 11 and can move up and down in the vertical direction along the vertical beam 11; the two gear and rack transmission groups 622 are respectively disposed at both ends of the moving block 621, and the gear and rack transmission groups 622 convert the vertical movement of the moving block 621 into the rotational movement of the rotating shaft 611.

[0035] Specifically, the gear and rack transmission assembly 622 includes a transmission rack 6221 and a transmission gear 6222. The transmission rack 6221 is disposed on one side of the moving block 621, and the transmission gear 6222 is coaxially connected to the rotating shaft 611, and the transmission gear 6222 meshes with the transmission rack 6221.

[0036] When the two support arms 61 are close to the vertical beam 11, the moving block 621 and the transmission racks 6221 on both sides are at the lower end of the line connecting the two transmission gears 6222. When it is necessary to unfold the support arms 61 to provide upward support force to the mounting arm 4, the moving block 621 drives the two transmission racks 6221 on both sides to move vertically upward. The moving direction, moving speed and moving distance of the two transmission racks 6221 are completely consistent. During the upward movement, the two transmission racks 6221 drive the two transmission gears 6222 to rotate in opposite directions, thereby driving the two rotating shafts 611 and the two support arms 61 to rotate in opposite directions. Through the design of the double gear rack drive driven by the moving block 621, the synchronous unfolding and retraction of the two support arms 61 are realized, ensuring that the two support arms 61 are always symmetrically distributed with the vertical beam 11 as the center, and applying a balanced support force to the mounting arm 4 from both sides.

[0037] Reference Figure 6 and Figure 7 As shown: The synchronous drive structure 62 also includes a guide structure 623, which is used to limit the moving direction and moving posture of the moving block 621.

[0038] Specifically, the guide structure 623 includes at least two guide rods 6231, both of which are parallel to the vertical beam 11 and are fixedly connected to the vertical beam 11 at both ends. The moving block 621 is slidably connected to the two guide rods 6231.

[0039] When the two suspension structures 2 switch to a horizontal left-right arrangement and the support arm 61 needs to be extended, the synchronous drive structure 62 is activated. The moving block 621 slides upward along the two parallel guide rods 6231. Because the guide rods 6231 are parallel to and fixedly connected to the vertical beam 11, they strictly limit the moving block 621 to move only in the vertical direction and prevent it from shifting in the horizontal direction. At the same time, they prevent the moving block 621 from tilting or rotating during the movement, ensuring that the moving block 621 always maintains a stable vertical posture. Therefore, the transmission racks 6221 on both sides of it also always remain in a vertical state. This allows the transmission racks 6221 to maintain a precise meshing state with the transmission gears 6222 during the upward movement. The meshing gap is always consistent, avoiding meshing jamming or tooth disengagement. This ensures that the power can be smoothly and efficiently transmitted to the transmission gears 6222, thereby driving the two transmission gears 6222 to rotate synchronously in opposite directions, thus avoiding transmission failures caused by the posture deviation of the moving block 621.

[0040] Reference Figure 5 and Figure 7 As shown: The synchronous drive structure 62 also includes a linkage rod 624, and both ends of the linkage rod 624 are provided with connecting shafts 6241. The two connecting shafts 6241 are respectively connected to the moving block 621 and the turntable 51.

[0041] When the suspension structure 2 needs to be switched from a vertical arrangement to a horizontal arrangement, as the turntable 51 rotates counterclockwise, the turntable 51 drives one end of the linkage rod 624 to move upward through the connecting shaft 6241. The linkage rod 624 then applies an upward pulling force to the moving block 621. Under the upward pulling force of the linkage rod 624, the moving block 621 moves vertically upward along the guide rod 6231. When the suspension structure 2 needs to be switched from a horizontal arrangement back to a vertical arrangement, as the turntable 51 rotates clockwise, the turntable 51 drives one end of the linkage rod 624 to move downward through the connecting shaft 6241. The linkage rod 624 applies a downward pushing force to the moving block 621. Under the pushing force of the linkage rod 624, the moving block 621 moves vertically downward along the guide rod 6231, thereby realizing the mechanical linkage between the turntable 51 and the moving block 621 and achieving synchronous coordination of their actions.

[0042] Reference Figure 5 and Figure 8 As shown: The support mechanism 6 also includes two second fixing structures 63, which are respectively disposed on the two support arms 61. The second fixing structures 63 are used to fix the support arms 61 and the mounting arms 4.

[0043] Specifically, the second fixing structure 63 includes a second threaded sleeve 631 and a second fixing rod 632. The second threaded sleeve 631 is disposed on the support arm 61, and the middle part of the second fixing rod 632 is an external threaded part, which is threadedly connected to the second threaded sleeve 631.

[0044] After the two support arms 61 are extended, the second fixing rod 632 is rotated. During the rotation, the second fixing rod 632 moves along the axis of the second threaded sleeve 631 until one end of the second fixing rod 632 is inserted into the mounting arm 4. At this time, the support arm 61 and the mounting arm 4 are rigidly fixedly connected through the second fixing structure 63. At this time, the downward force borne by the mounting arm 4 due to the suspension of the casting will be stably transmitted to the support arm 61 through the second fixing rod 632, and then transmitted from the support arm 61 to the moving frame 1 through the pivot 611 and the vertical beam 11, forming a complete force transmission path. This avoids the mounting arm 4 from being deflected due to contact support alone. Moreover, there is a self-locking effect between the second fixing rod 632 and the second threaded sleeve 631. During the movement of the hanger, the connection point between the support arm 61 and the mounting arm 4 will not be broken, thus ensuring that the support arm 61 can always provide effective support for the mounting arm 4 when the hanger is transporting large-sized castings.

[0045] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
