Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, specifically a buffer device for a transfer rack in automobile manufacturing. Background Technology

[0002] In the process of manufacturing automotive parts, parts need to be transferred across processes within the workshop. Usually, a mobile frame is used in conjunction with a carrying fixture to complete the transport. To ensure safe passage within the workshop, speed bumps are generally installed on factory roads and at workshop corners. In addition, there are gaps and slight unevenness in the ground, which can easily cause bumps and vibrations when transport vehicles pass through these areas. In existing technologies, most loading fixtures employ rigid frame structures of fixed dimensions. Consequently, when traversing speed bumps, these rigid structures lack the ability to buffer and absorb shocks. The impacts generated during transport are directly transmitted to the parts, easily causing scratches, deformation, and damage to precision components. This directly affects the quality of the parts and the accuracy of subsequent assembly, increasing production losses and rework costs. Therefore, those skilled in the art have provided a buffer device for transport racks in automobile manufacturing to address the problems mentioned in the background. Summary of the Invention

[0003] The purpose of this invention is to provide a buffer device for a transfer rack in automobile manufacturing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A buffer device for a transfer rack in automobile manufacturing includes four L-shaped corner plates and a carrying frame. The four L-shaped corner plates are located at the four corners to form a rectangle. A lateral adjustment component is provided between each pair of L-shaped corner plates on the two long sides of the rectangle, and a longitudinal adjustment component is provided between each pair of L-shaped corner plates on the two short sides of the rectangle. The four L-shaped corner plates, two pairs of lateral adjustment components, and two pairs of longitudinal adjustment components form a rectangular frame, and the carrying frame is snapped onto the rectangular frame.

[0005] Furthermore, the longitudinal adjustment assembly includes a longitudinal telescopic rod and a longitudinal telescopic sleeve. The longitudinal telescopic rods are fixedly connected to the opposite surfaces of the two L-shaped corner plates on the short side of the rectangular frame, and the longitudinal telescopic sleeves are sleeved on the two longitudinal telescopic rods.

[0006] Furthermore, the lateral adjustment assembly includes lateral telescopic rods and lateral telescopic sleeves. Horizontal telescopic rods are fixedly connected to the opposite surfaces of the two L-shaped corner plates on the long side of the rectangular frame, and lateral telescopic sleeves are sleeved on the two lateral telescopic rods.

[0007] Furthermore, the longitudinal telescopic rod and the longitudinal telescopic sleeve are provided with a first locking member, and the transverse telescopic rod and the transverse telescopic sleeve are provided with a second locking member, and the first locking member and the second locking member are provided in the same way.

[0008] Furthermore, the first locking component includes a locking threaded rod and a threaded sleeve. The lower part of the longitudinal telescopic rod is fixedly connected to the threaded sleeve, and the locking threaded rod is threadedly connected to the threaded sleeve. A sliding groove is provided on the lower surface of the longitudinal telescopic sleeve, and the rod part of the locking threaded rod passes through this sliding groove. The head of the locking threaded rod is tightened by the threaded sleeve and abuts against the longitudinal telescopic sleeve.

[0009] Furthermore, each L-shaped corner plate has a shock-absorbing component fixedly connected to its lower surface, and the rectangular frame is placed on an external movable frame through this shock-absorbing component.

[0010] Furthermore, the shock absorber includes a damping spring, a sliding pad, and a sliding sleeve. The sliding sleeve is fixedly connected to the lower surface of the L-shaped corner plate, the sliding pad is slidably connected inside the sliding sleeve, and the damping spring is fixedly connected to the top wall inside the sliding sleeve. The lower end face of the damping spring is fixedly connected to the bottom wall inside the sliding pad.

Addressing the industry pain point that parts transportation in automobile manufacturing workshops is prone to bumps and damage caused by speed bumps at corners, this device is equipped with independent shock absorbers at the bottom of each of the four L-shaped corner plates. Through the damping springs, sliding sleeves and sliding pads, an elastic buffer structure is formed, which can fully absorb the vibration and impact caused by speed bumps and uneven road surfaces during transportation, greatly reducing the risk of parts being damaged by bumps and effectively ensuring parts yield and production quality. 2. Through the telescopic sleeve structure of the horizontal adjustment component and the vertical adjustment component, the length and width of the rectangular frame can be flexibly adjusted to adapt to different specifications of cargo frames and automotive parts, meet the transportation needs of multiple vehicle models and multiple types of parts, and eliminate the need to customize special transportation tooling for different parts, effectively reducing production support costs. 3.

[0014] Please see Figs. 1-4 The present invention provides an embodiment of a buffer device for a transfer rack in automobile manufacturing, comprising L-shaped corner plates 1 and a loading frame 2. There are four L-shaped corner plates 1, which are located at the four corners to form a rectangle. A lateral adjustment component is provided between each pair of L-shaped corner plates 1 on the two long sides of the rectangle, and a longitudinal adjustment component is provided between each pair of L-shaped corner plates 1 on the two short sides of the rectangle.

Four L-shaped corner plates are arranged at the four corners to form a rectangular outline. A horizontal adjustment component is set between each pair of L-shaped corner plates on the two long sides of the rectangle, and a vertical adjustment component is set between each pair of L-shaped corner plates on the two short sides of the rectangle. The four L-shaped corner plates, two pairs of horizontal adjustment components and two pairs of vertical adjustment components are assembled together to form a telescopic and adjustable rectangular frame. The loading frame 2 is assembled on the rectangular frame by snap-fit ​​and is used to carry automobile manufacturing parts.

[0015] In this embodiment, the longitudinal adjustment component includes a longitudinal telescopic rod 5 and a longitudinal telescopic sleeve 6.

Two L-shaped corner plates located on the short side of the rectangle are each fixedly connected to a longitudinal telescopic rod 5 on their opposite sides. The free ends of the two longitudinal telescopic rods 5 are fitted into the same longitudinal telescopic sleeve 6. The size adjustment of the short side of the rectangular frame is achieved by the relative sliding of the telescopic rods and the telescopic sleeve.

[0016] In this embodiment, the lateral adjustment component includes a lateral telescopic rod 3 and a lateral telescopic sleeve 4. The two L-shaped corner plates 1 on the long side of the rectangular frame are respectively fixedly connected to the opposite surfaces of the lateral telescopic rods 3, and the lateral telescopic sleeves 4 are sleeved on the two lateral telescopic rods 3. Two L-shaped corner plates located on the long side of the rectangle are each fixedly connected to a horizontal telescopic rod 3 on their opposite sides. The free ends of the two horizontal telescopic rods 3 are fitted into the same horizontal telescopic sleeve 4. The size adjustment of the long side of the rectangular frame is achieved by the relative sliding of the telescopic rods and the telescopic sleeve.

[0017] In this embodiment, a first locking element a is provided on the longitudinal telescopic rod 5 and the longitudinal telescopic sleeve 6, and a second locking element b is provided on the transverse telescopic rod 3 and the transverse telescopic sleeve 4. The first locking element a and the second locking element b are similarly provided. The first locking element a includes a locking threaded rod 7 and a threaded sleeve 8. The lower part of the longitudinal telescopic rod 5 is fixedly connected to the threaded sleeve 8, and the locking threaded rod 7 is threadedly connected to the threaded sleeve 8. A sliding groove 9 is provided on the lower surface of the longitudinal telescopic sleeve 6, and the rod part of the locking threaded rod 7 passes through this sliding groove 9. The head of the locking threaded rod 7 is tightened by the threaded sleeve 8 and abuts against the longitudinal telescopic sleeve 6. A first locking element a is provided between the longitudinal telescopic rod 5 and the longitudinal telescopic sleeve 6, and a second locking element b is provided between the transverse telescopic rod 3 and the transverse telescopic sleeve 4. The first locking element a and the second locking element b have the same structural principle. Taking the first locking component a as an example, it includes a locking threaded rod 7 and a threaded sleeve 8; the lower part of the longitudinal telescopic rod 5 is fixedly connected to the threaded sleeve 8, and the locking threaded rod 7 is threadedly engaged in the threaded sleeve 8; the lower surface of the longitudinal telescopic sleeve 6 is provided with a sliding groove 9 extending along the length direction, the rod part of the locking threaded rod 7 passes through the sliding groove 9 and can slide along the sliding groove 9. When the frame size is adjusted to the correct position, the locking threaded rod 7 is rotated, so that the head of the locking threaded rod 7 is pressed against the outer wall of the longitudinal telescopic sleeve 6 under the feeding action of the threaded sleeve 8, and the relative position of the telescopic rod and the telescopic sleeve is locked by friction, thus completing the size fixation; the second locking component b locks the transverse adjustment component in the same way.

[0018] In the embodiment, each L-shaped corner plate 1 is fixedly connected to a shock absorber c on its lower surface, and the rectangular frame is placed on an external movable frame through the shock absorber c. The shock absorber c includes a damping spring 10, a sliding pad 11 and a sliding sleeve 12. The sliding sleeve 12 is fixedly connected to the lower surface of the L-shaped corner plate 1, the sliding pad 11 is slidably connected inside the sliding sleeve 12, and the damping spring 10 is fixedly connected to the top wall of the inner wall of the sliding sleeve 12. The lower end face of the damping spring 10 is fixedly connected to the bottom wall of the inner wall of the sliding pad 11. Each L-shaped corner plate has a shock absorber c fixedly connected to its lower surface. The entire rectangular frame is placed on the external moving frame by four sets of shock absorbers c. A sliding sleeve 12 with its opening facing downward is fixedly connected to the lower surface of the L-shaped corner plate. A sliding pad 11 is slidably connected inside the sliding sleeve 12. The lower end of the sliding pad 11 is used to contact the external moving frame. A damping spring 10 is fixedly connected to the inner top wall of the sliding sleeve 12. The lower end of the damping spring 10 is fixedly connected to the inner bottom wall of the sliding pad 11. When the external moving frame passes through speed bumps or uneven road surfaces and causes bumps, the sliding pad 11 slides up and down along the inside of the sliding sleeve 12. The elastic deformation of the damping spring 10 absorbs the vibration energy and weakens the impact transmitted to the loading frame 2 and the parts.

[0019] Working principle: In use, first, according to the specifications of the parts to be transported and the carrying frame 2, loosen the locking thread rods 7 of each locking component, push and pull the L-shaped corner plate along the sliding groove 9, and adjust the length and width of the rectangular frame through the horizontal adjustment component and the vertical adjustment component; after the size is adapted to the carrying frame 2, tighten each locking thread rod 7 to complete the frame locking, then snap the carrying frame 2 onto the rectangular frame, place the parts in the carrying frame 2, and during the transport process, the shock absorbers c at the four corners synchronously buffer the bumps and vibrations generated by the external moving frame to avoid damage to the parts due to impact and collision; at the same time, the locking structure can prevent the frame size from shifting during vibration and ensure the stability of the load-bearing state.

[0020] Addressing the industry pain point of parts transportation in automotive manufacturing workshops being prone to bumps and damage from speed bumps at corners, this device features independent shock absorbers (c) at the bottom of each of the four L-shaped corner plates. These shock absorbers, through damping springs (10), sliding sleeves (12), and sliding pads (11), form an elastic buffer structure that effectively absorbs vibrations and impacts caused by speed bumps and uneven road surfaces during transport, significantly reducing the risk of parts damage and ensuring part yield and production quality. The telescopic connection structure of the lateral and longitudinal adjustment components allows for flexible adjustment of the rectangular frame's length and width, accommodating different specifications of cargo frames (2) and automotive parts, meeting the transport needs of multiple vehicle models and parts categories. This eliminates the need for customized transport fixtures for different parts, effectively reducing production costs. The lateral and longitudinal adjustment components are equipped with corresponding locking mechanisms. By using a locking threaded rod (7) that slides along the sliding groove (9) and tightens, a stable lock can be achieved at any adjusted size, preventing dimensional shifting of the frame and displacement of the cargo frame (2) during transport. Combined with the bottom shock absorber structure, this further enhances overall load-bearing stability and reduces the risk of parts collisions.

Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
