Description

Technical Field

[0001] This utility model relates to the field of flaw detection auxiliary equipment technology, and in particular to an automated X-ray flaw detection fixing device for castings of rear longitudinal beams and shock absorber towers of vehicle bodies. Background Technology

[0002] Integrated die casting of new energy vehicle body structural components is a major trend. Currently, automakers are adopting integrated die casting designs for vehicle development and design, and there are strict requirements for the internal quality of the products during the development process. Dedicated X-ray flaw detection equipment is needed in both the early stages of product development and the later stages of mass production to identify and determine internal quality defects.

[0003] For example, announcement number CN117619752B was published on August 20, 2024. This announcement discloses a non-destructive testing device for vehicle parts, relating to the field of parts inspection technology. It includes a base plate, a rotating rod with a rotating disk fixedly connected to the end away from the first motor, a positioning post fixedly connected to the side of a fixed plate near the rotating disk, a rotating groove on the outer wall of the positioning post, a rotating plate rotatably connected to the positioning post through the rotating groove, a sliding post fixedly connected to the side of the rotating disk away from the fixed plate, a sliding groove on the outer wall of the rotating plate, a first mounting plate fixedly connected to the side of the rotating plate away from the rotating disk, and a detection probe and a high-intensity lamp fixedly connected to the bottom of the first mounting plate. The aforementioned disclosed equipment cannot perform flaw detection work on the rear longitudinal beam and shock absorber tower castings of the vehicle body after providing stable support, resulting in poor practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a more practical automated X-ray flaw detection and fixing device for the rear longitudinal beam and shock absorber tower castings of a vehicle body. This invention achieves stable fixing of the longitudinal beam and shock absorber tower through a first slot on the shock absorber tower holder and a second slot on the longitudinal beam holder, thereby facilitating the fixing of the longitudinal beam and shock absorber tower within the flaw detection equipment for flaw detection work, thus improving its practicality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: an automated X-ray flaw detection and fixing device for a vehicle rear longitudinal beam and shock absorber tower casting, comprising a shock absorber tower holder and a longitudinal beam holder that are interlocked with each other, wherein the longitudinal beam holder is provided with a first slot and the shock absorber tower holder is provided with a second slot that interlocks with the longitudinal beam holder.

[0006] The longitudinal beam bracket is provided with a positioning column, and the shock absorber tower bracket is provided with a positioning groove that engages with the positioning column.

[0007] The first slots on the longitudinal beam holder are symmetrically arranged.

[0008] The positioning slot is located in the second slot.

[0009] The shock absorber tower bracket is provided with a base, the base is provided with connecting bolts, and the base is provided with through holes for the connecting bolts to pass through.

[0010] Both the first card slot and the second card slot are rectangular slots.

[0011] An elastic pad is provided at the connection between the positioning column and the longitudinal beam seat.

[0012] The beneficial effects of this utility model are:

[0013] The first slot on the damper tower holder and the second slot on the longitudinal beam holder ensure stable fixation of the longitudinal beam and damper tower, facilitating their placement within the flaw detection equipment for flaw detection. The damper tower holder and longitudinal beam holder can be switched quickly, reducing production costs. Furthermore, the longitudinal beam holder has a positioning post, and the damper tower holder has a positioning groove that engages with the positioning post. The precise connection between the longitudinal beam holder and the damper tower holder is achieved through the cooperation of the positioning post and the positioning groove, enhancing practicality.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] like Figure 1-3As shown, the X-ray automated flaw detection and fixing device for the rear longitudinal beam and shock absorber tower casting of the vehicle body includes a shock absorber tower holder 1 and a longitudinal beam holder 2 that are interlocked. The longitudinal beam holder 2 is provided with a first slot 3, which is used to clamp the longitudinal beam. The shock absorber tower holder 1 is provided with a second slot 4 that is interlocked with the longitudinal beam holder 2. The second slot 4 not only realizes the connection between the shock absorber tower holder 1 and the longitudinal beam holder 2, but also clamps the shock absorber tower through the second slot 4.

[0021] In use, the interlocking damper tower holder 1 and longitudinal beam holder 2 are placed inside the flaw detection equipment. The longitudinal beam is installed in the first slot 3 on the longitudinal beam holder 2 for flaw detection. Then, after the longitudinal beam holder 2 is removed from the second slot 4 of the damper tower holder 1, the damper tower is placed in the second slot 4 for flaw detection. The mutual cooperation between the damper tower holder 1 and the longitudinal beam holder 2 achieves stable clamping of the damper tower and longitudinal beam on the flaw detection equipment, thus facilitating flaw detection of the damper tower and longitudinal beam and improving its practicality.

[0022] The longitudinal beam bracket 2 is provided with a positioning post 8, and the shock absorber tower bracket 1 is provided with a positioning groove 9 that engages with the positioning post 8. The stable connection between the longitudinal beam bracket 2 and the shock absorber tower bracket 1 is achieved through the cooperation of the positioning post 8 and the positioning groove 9. Specifically, the end of the positioning post 8 is chamfered to facilitate insertion into the positioning groove 9. The positioning post 8 is located at the lower middle position of the longitudinal beam bracket 2.

[0023] The first slots 3 on the longitudinal beam holder 2 are symmetrically arranged so that when the longitudinal beam is installed in the first slot 3, the longitudinal beam is placed stably in the longitudinal beam holder 2, which facilitates the flaw detection equipment to perform flaw detection work. In this embodiment, there are two first slots 3.

[0024] The positioning groove 9 is set in the second slot 4, thereby realizing the stable engagement of the longitudinal beam bracket 2 in the first slot 4 of the shock absorber bracket 1. The positioning groove 9 is located in the middle of the second slot 4.

[0025] The shock absorber tower mounting base 1 is provided with a base 5, and the base 5 is provided with connecting bolts 6. The base 5 is provided with through holes 7 for the connecting bolts 6 to pass through. The base 5 and the entire fixing device are installed on the flaw detection equipment through the connecting bolts 6. Specifically, there are four connecting bolts 6.

[0026] Both the first slot 3 and the second slot 4 are rectangular slots, which facilitates the rapid installation of the shock absorber tower and longitudinal beam.

[0027] An elastic pad 10 is provided at the connection between the positioning column 8 and the longitudinal beam bracket 2. The elastic pad 10 provides elastic protection for the longitudinal beam bracket 2 and the positioning column 8 during installation in the second slot 4.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
