Description

Technical Field

[0001] This application belongs to the field of automotive body manufacturing tooling technology, specifically relating to a vehicle body longitudinal beam hook device. Background Technology

[0002] The longitudinal beams of the vehicle body frame, often simply referred to as longitudinal beams, are the main load-bearing structural components arranged along the length of the vehicle (from front to rear) on the vehicle body frame or chassis. They are the "backbone" of the vehicle body structure and the most critical component for bearing and transmitting loads. Positioning and fixing the longitudinal beams is a key process in vehicle body manufacturing and assembly. Generally, the longitudinal beams are hooked and lifted up before vehicle body manufacturing and assembly.

[0003] In existing technologies, rigid clamps or simple hooks are often used to hook and lift the longitudinal beams of the vehicle body before transferring them. However, during the hooking process, because the specifications of the hooks are fixed, they cannot adapt to longitudinal beams of different thicknesses. As a result, it is necessary to replace the hooks with other specifications, which makes the existing hooks unsuitable, complicated to operate, inconvenient to adjust, and affects assembly efficiency.

[0004] To address the above issues, this application designs a vehicle body longitudinal beam hook device to solve the technical problems of difficulty in adapting to vehicle body longitudinal beams of different thicknesses, complex operation, inconvenient adjustment, and impact on assembly efficiency. Utility Model Content

[0010] In some possible embodiments, the synchronous pushing component includes: a synchronous plate, fixed to the upper right side of the lifting plate; a pressure block, fixed to the upper left part of the synchronous plate, with the lower end of the pressure block being inclined, and the inclined surface of the pressure block matching the inclined surface of the push block; and several rollers, all rotatably connected to the lower end of the pressure block, with the rollers contacting the inclined surface of the push block.

[0011] In some possible embodiments, the upper left part of the hook body has a hook connection hole that runs through the left and right sides.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0021] The following reference Figures 1 to 3 This application describes a vehicle body longitudinal beam hook device according to some embodiments.

[0022] Please see Figures 1 to 3 This application provides a vehicle body longitudinal beam hook device in some embodiments. In some embodiments, the device includes a hook body 1; a support plate 2, located in the lower part of the hook body 1 and used to support the vehicle body longitudinal beam; and an elastic support assembly located below the support plate 2, used to apply elastic support force to the vehicle body longitudinal beam on the support plate 2 and provide buffer protection. The elastic support assembly includes: a base plate 201, fixed to the upper left side of the lifting plate 4; four support rods 202, all fixed between the support plate 2 and the base plate 201, and the support rods 202 slide longitudinally through the hook body 1; and two spring tension rods 203, both fixed to the upper end of the base plate 201, with the free end of the spring tension rods 203 fixed to the lower part of the hook body 1.

[0023] In this embodiment, when the vehicle body longitudinal beam is hooked by the hook device, the support plate 2 is used to support the vehicle body longitudinal beam. At this time, the weight of the vehicle body longitudinal beam itself will press down on the support plate 2. Since the support plate 2 is supported by the elastic support component, the gravity will push the support rod 202 and the bottom plate 201 downward, thereby driving the spring tension rod 203 to stretch. Therefore, it is beneficial to apply elastic support force to the vehicle body longitudinal beam on the support plate 2 and provide buffer protection through the elastic support component.

[0024] In some embodiments, a side clamping plate 3 is located on the right side inside the hook body 1; an elastic clamping assembly is located to the right of the side clamping plate 3 for driving the side clamping plate 3 to clamp the vehicle longitudinal beams of various thicknesses; a lifting plate 4 is located below the hook body 1; and a synchronous pushing assembly is located above the base plate 4 to drive the elastic clamping assembly to push the side clamping plate 3 to clamp the vehicle longitudinal beams of various thicknesses. The elastic clamping assembly includes: a push block 301, which is located on the right side of the hook body 1, and the upper end of the push block 301 is inclined; a push rod 302, which is fixed between the side clamping plate 3 and the push block 301, and the push rod 302 slides laterally through the hook body 1; and two return springs 303, which are connected to each other between the hook body 1 and the push block 301. The synchronous pushing assembly includes: a synchronous plate 401, which is fixed on the upper right side of the lifting plate 4; a pressure block 402, which is fixed on the upper left part of the synchronous plate 401, and the lower end of the pressure block 402 is inclined, and the inclined surface of the pressure block 402 matches the inclined surface of the push block 301; and several rollers 403, which are rotatably connected to the lower end of the pressure block 402, and the rollers 403 are in contact with the inclined surface of the push block 301.

[0025] In this embodiment, when the longitudinal beam of the vehicle body is supported by the support plate 2, the base plate 201 is pushed down by gravity, so the base plate 201 will push the lifting plate 4, the synchronous plate 401 and the pressure block 402 downward. Since the pressure block 402 matches the inclined surface of the push block 301, the roller 403 will roll down along the inclined surface of the push block 301. At this time, the pressure block 402 will apply a leftward pushing force to the push block 301. At the same time, the push block 301 will push the push rod 302 and the side clamping plate 3 closer to the longitudinal beam of the vehicle body until the side clamping plate 3 clamps the longitudinal beam of the vehicle body into the hook body 1. Moreover, the heavier the longitudinal beam of the vehicle body, the greater the pressure of the pressure block 402 on the push block 301. The greater the thrust of the side clamping plate 3, the greater the clamping force of the side clamping plate 3 on the longitudinal beam of the vehicle body, effectively solving the problem of insufficient clamping force of the longitudinal beam of the vehicle body. In summary, this is conducive to clamping longitudinal beams of various thicknesses, so that the hook device can adapt to longitudinal beams of different thicknesses, ensuring stable clamping force. Furthermore, the synchronous pushing component facilitates the linkage between lifting and clamping, making operation and adjustment simple and improving assembly efficiency. Therefore, the hook device has high reliability, helps prevent the longitudinal beam of the vehicle body from falling during lifting, ensures a smooth lifting process, improves the safety of lifting the longitudinal beam, and is suitable for various hooking scenarios of longitudinal beams of the vehicle body.

[0026] In some embodiments, the hook body 1 has a hook connection hole 5 that runs through the left and right sides at the upper left part.

[0027] In this embodiment, by setting the hook connection hole 5, it is convenient to install the hook body 1 onto the hoist chain. When actually hooking and lifting the longitudinal beam of the vehicle body, with the premise of preparing four hook devices, the four hook bodies 1 are respectively installed at the lifting point positions of the four hooks of the hoist. Then, the longitudinal beam of the vehicle body is lifted by the cooperation of the four hook devices to avoid serious shaking during the lifting process and reduce the safety hazards caused by manual handling.

[0028] In some embodiments, a left buffer pad 6 is connected to the left inner wall of the hook body 1, a lower buffer pad 7 is connected to the upper surface of the support plate 2, and a right buffer pad 8 is connected to the left side of the side clamping plate 3.

[0029] In this embodiment, by setting the left buffer pad 6, the lower buffer pad 7 and the right buffer pad 8, when the support plate 2 supports the longitudinal beam of the vehicle body, the lower buffer pad 7 helps to buffer and protect the underside of the longitudinal beam of the vehicle body. When the side clamping plate 3 clamps the longitudinal beam of the vehicle body into the hook body 1, the cooperation of the left buffer pad 6 and the right buffer pad 8 helps to buffer and protect the left and right sides of the longitudinal beam of the vehicle body, effectively preventing damage to the surface of the longitudinal beam.
