Description

Technical Field

[0001] This utility model relates to the field of vehicle transfer technology, and in particular to a transfer case transfer rack. Background Technology

[0002] With the rapid development of the automotive industry, especially heavy-duty truck manufacturing processes, the transfer case, as a key component connecting the transmission and drive system, directly affects the transmission performance and reliability of the entire vehicle due to its structural stability and assembly precision. This type of transfer case is typically a one-piece cast metal structure with a high self-weight. Its shape is roughly rectangular, with the front axle output shaft side of the housing generally featuring an arc shape or a multi-plane combination structure, while the input shaft side usually has a metal lifting ring or a lifting structure for easy hoisting, serving as a connection point for robotic arms or lifting devices during handling.

[0003] On today's highly automated vehicle assembly lines, transfer cases often need to be picked up from above by a robotic arm and placed into the production line. Therefore, before the transfer case enters the assembly line, it must be placed in a vertical position with the "lifting ring facing up".

[0004] However, in existing technologies, most transfer cases are stored and transported using the traditional horizontal placement method, requiring manual adjustments such as straightening, removing protective measures, and changing the direction of the lifting rings before assembly. This method not only increases the cost of manual intervention but also suffers from repetitive handling, unstable posture, and inability to quickly connect with robotic arms, thus reducing the overall production cycle and assembly efficiency.

[0005] Therefore, based on the structural characteristics of the transfer case, a support and handling device needs to be designed that can maintain the natural upward orientation of its lifting rings throughout the entire transfer process. Summary of the Invention

[0006] In view of the problems existing in the above-mentioned transfer box transfer frame, this utility model is proposed.

[0007] Therefore, one of the objectives of this utility model is to provide a transfer box transfer rack, which aims to solve the problem of placing the lifting ring upwards during the loading process of the transfer box.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: including,

[0009] The base has a supporting structure on it;

[0010] A support structure, the support structure comprising a first support block and a second support block;

[0011] The first support block and the second support block are respectively provided with a first support surface and a second support surface on their tops, and the first support surface and the second support surface are arranged opposite to each other, and the first support surface and the second support surface respectively abut against the housing below the front axle output shaft of the transfer case.

[0012] As a preferred embodiment of the transfer box transfer frame of this utility model, the first support surface and the second support surface are both arranged at an angle, and the first support surface and the second support surface are respectively inclined towards the opposite support surface, forming an inverted V-shaped structure that is wider at the top and narrower at the bottom.

[0013] As a preferred embodiment of the transfer box transport frame of this utility model, the support structure further includes a mounting plate, and the left and right ends of the mounting plate are movably connected to the first support block and the second support block.

[0015] In a preferred embodiment of the transfer case transport frame of this utility model, the limiting component includes a first support column and a second support column, which are respectively disposed on the front and rear sides of the first support block and the second support block.

[0016] In a preferred embodiment of the transfer case transfer frame of this utility model, the limiting component further includes a support frame, and a fixing rod is provided on the top of the support frame.

[0020] In a preferred embodiment of the transfer box transport frame of this utility model, the top of the first pillar and the second pillar are both fixedly connected to a support block, and the top of the support block is provided with a buffer pad.

[0021] The beneficial effects of this utility model are as follows: By setting a fixed rod, a first support column, a second support column, and an adjustable support structure, the transfer case is ensured to remain in an upward position, making it easy to lift when entering the assembly line. This effectively improves the stability and anti-tipping ability of the transfer case during transportation. Moreover, it has high model adaptability and adjustability, reduces the difficulty of manual loading and unloading, and improves the efficiency of installation and fixing.

[0028] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0030] Example 1, referring to Figure 1 , 23, being the first embodiment of this utility model, provides a transfer case transfer frame. This device includes a base 100 on which a support structure 200 is provided. The support structure 200 includes a first support block 201 and a second support block 202. The tops of the first support block 201 and the second support block 202 are respectively provided with a first support surface 201a and a second support surface 202a, and the first support surface 201a and the second support surface 202a are arranged opposite to each other. The first support surface 201a and the second support surface 202a respectively abut against the outer shell on the opposite side of the transfer case lifting ring. The first support surface 201a and the second support surface 202a are both arranged obliquely, and the first support surface 201a and the second support surface 202a are respectively inclined towards the opposite support surface, forming an inverted V-shaped structure that is wider at the top and narrower at the bottom.

[0031] In traditional applications, after placing the transfer case on a conventional transfer rack, the transfer case lies flat with the lifting ring positioned low, hindering subsequent assembly and gripping. To achieve precise gripping and efficient docking of the transfer case on the assembly line, this embodiment places the transfer case vertically on the transfer rack, with its top lifting ring naturally facing upwards. The transfer case is positioned on the side of the transfer rack relative to the lifting ring, which in this design is near the front axle output shaft. Since the transfer case has one input end and two output ends (front axle output shaft and rear axle output shaft), the input end and rear axle output shaft are generally coaxial, while the front axle output shaft is positioned along the housing on the opposite side of the input end. Therefore, to lift the transfer case, the lifting ring is positioned along the central axis of the housing near the input end and the rear axle output shaft. The other end along the central axis forms the bottom support surface used to support the transfer case in this embodiment.

[0032] Specifically, such as Figure 1 , 2 As shown in Figure 3, the support structure 200 set on the base 100 includes a first support block 201 and a second support block 202, which are arranged opposite to each other and are used to clamp the bottom of the transfer case. The top of the first support block 201 and the second support block 202 are respectively provided with a first support surface 201a and a second support surface 202a. The two support surfaces are arranged opposite to each other and structurally form corresponding contact areas with the two sides of the bottom of the transfer case.

[0033] To ensure support stability and installation fit, the support surfaces 201a and 202a adopt a large flat contact design. That is, after the transfer case is placed, the first support surface 201a and the second support surface 202a can simultaneously form contact with its bottom sides, thereby providing sufficient support.

[0034] It is important to note that, in order to provide stability, the surface can be set according to the shape of the bottom support surface of different transfer cases. In addition to flat surfaces, convex or concave surfaces can also be used as contact surfaces to make the contact area larger and the support effect better. This allows the transfer case to maintain its initial posture stability even in a vertical state with a high center of gravity, providing a foundation for subsequent fixation.

[0035] Example 2, refer to Figure 4 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a limiting component 300 is provided on the base 100. The limiting component 300 includes multiple limiting members disposed around the support structure 200. The limiting members are either fixed or adjustable, enclosing an installation area for accommodating the transfer case. The limiting component 300 includes a first pillar 301 and a second pillar 302, which are respectively disposed on the front and rear sides of the first support block 201 and the second support block 202. The limiting component 300 also includes a support frame 303. A fixing rod 304 is provided on the top of the support frame 303. A connecting mechanism 305 is provided at the center of the top of the support frame 303. The connecting mechanism 305 is connected to the fixing rod 304. The height of the fixing rod 304 is higher than the height of the support structure 200, the first pillar 301, and the second pillar 302, and the top of the first pillar 301 is higher than the top of the second pillar 302.

[0036] Compared to Embodiment 1, this embodiment further provides support frames 303 on both sides of the base 100 and a fixing rod 304 on the top of the support frame 303. The constraint force at the top compensates for the instability caused by the high center of gravity of the transfer case, significantly improving the anti-disturbance capability in the vertical transportation state.

[0037] The fixed rod 304 is significantly higher than the supporting structure 200 below and the first and second pillars 301 and 302 located on its front and rear sides, ensuring that the transfer case can be traction-type limited from above the lifting ring after it is placed. During transportation, the fixed rod 304 provides tension through the connection formed with the transfer case lifting ring, effectively suppressing the transfer case swaying caused by vehicle vibration or uneven ground.

[0038] Furthermore, the first support column 301 and the second support column 302 are respectively disposed on the front and rear sides of the first support block 201 and the second support block 202, and their main function is to provide local support and limit the forward and backward protruding drive shaft structure of the transfer case. Considering that the output shafts on both sides of the transfer case axis are not uniformly symmetrically arranged, generally speaking, the rear axle output shaft is higher than the front axle output shaft when suspended. Therefore, the top of the first support column 301 is preferably set slightly higher than the second support column 302 to achieve height matching of the drive shaft centerline, thereby enhancing the fit of the front and rear supports.

[0039] During the connection between the fixed rod 304 and the top lifting ring of the transfer case, using a common fixed hook connection would not only limit the flexibility of installation but also cause installation difficulties or structural tension eccentricity due to positioning errors. Specifically, the hook at the end of the fixed rod 304 needs to hook into the lifting ring and provide a certain rigidity, so it is generally welded to the fixed rod 304. If the position of the transfer case hook is too far out or too far in, it may be difficult to reach the specified position by relying on the range of rotation, thus leading to the inability to install. To solve this problem, this embodiment provides a parallel connecting plate at one end of the fixed rod 304. The connecting plates are arranged opposite each other, thus leaving a large insertion space. The connecting plate has a rectangular connecting groove for efficient and reliable assembly with the top lifting ring of the transfer case. The rectangular connecting groove has a long opening in its structure and can be locked to the lifting ring by bolts. The preferred distance between the connecting plates is the thickness of the lifting ring. After the lifting ring is inserted, pressure is applied to provide a stable fixing force to the transfer case. This allows for greater flexibility in position adjustment and installation tolerances, while enabling the operator to quickly align and complete the fixing operation.

[0040] Compared to the traditional round hole positioning method, the rectangular groove structure provides a wider range of adjustment, avoiding installation failures caused by inaccurate hole positioning or oblique bolt insertion, and ensuring that the top fixing rod 304 can continuously provide effective constraint on the transfer case when in a pulled state.

[0041] The remaining structure is the same as that in Example 1.

[0042] Example 3, referring to Figure 5 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the support structure 200 further includes a mounting plate 203. The left and right ends of the mounting plate 203 are movably connected to the first support block 201 and the second support block 202. The first pillar 301 and the second pillar 302 are both movably connected to the base 100. The top of the first pillar 301 and the second pillar 302 are both fixedly connected to the support block 306. The top of the support block 306 is provided with a buffer pad 307.

[0043] Compared to Embodiment 2, to further improve the adaptability of the transfer case transport frame to different equipment models, the support structure 200 has been modularly adjusted. The mounting plate 203 connects the first support block 201 and the second support block 202 via a sliding connection and is secured with bolts, making the distance between the first support block 201 and the second support block 202 adjustable. Alternatively, it can be adjusted via a threaded rod or fixed using multiple insertion holes, thus adapting to transfer cases of various widths. To further enhance the adaptability of the top support structure, a connecting mechanism 305 is provided at the top of the support frame 303. This can employ a multi-hole connection method, where different mounting holes are selected from a linearly arranged array to adjust the insertion position of the fixing rod 304, resulting in a simple structure and clear positioning. Alternatively, a sliding block connection can be used, with a sliding seat assembly at the lower end of the fixing rod 304, allowing horizontal sliding on the top of the connecting support frame 303 and positioning via a locking structure, providing strong adjustment continuity and ease of operation. Alternatively, a sliding connection driven by a threaded rod can be used. By further introducing a screw mechanism, the fixed rod 304 can be smoothly moved in the guide rail through rotational operation, achieving a precision adjustment function. This allows for position adjustment of the fixed rod 304 and high-precision docking with different transfer case lifting rings.

[0044] In vertical transport mode, to prevent the transfer case from shaking and protect the shaft end, this embodiment provides support blocks 306 on the top of both the first support column 301 and the second support column 302, and covers them with buffer pads 307. The buffer pads 307 can be made of rubber or other materials with good plasticity to improve the fit with the transfer case and avoid poor local contact caused by adjusting the clearance, which could lead to shaking during movement. At the same time, the surfaces of the first support surface 201a and the second support surface 202a can also be provided with additional pads to cushion the impact on the support parts and improve the contact life of the first support surface 201a and the second support surface 202a.

[0045] To balance handling efficiency and structural symmetry, the support structure 200 and its related structures are all configured in two sets, symmetrically arranged on both sides of the base 100, allowing for the simultaneous placement of two transfer cases and thus balancing the forces during handling. Reinforcing frames are installed around the base 100, with insertion holes formed within them for easy forklift arm operation. Multiple casters are also installed at the bottom of the transfer frame, positioned to avoid obstructing the insertion holes, enabling flexible short-distance movement within the factory. The overall structure possesses excellent adaptability, stability, and handling efficiency.

[0046] The remaining structure is the same as that in Example 2.
