Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a fixture for inspecting automotive thermoformed parts. Background Technology

[0002] Automotive hot-formed parts refer to automotive components manufactured using hot stamping technology. Hot stamping is a forming method in which sheet metal is heated to a suitable temperature above its recrystallization temperature, and then stamped based on the characteristics of the material that its resistance to deformation decreases and its plasticity increases at high temperatures.

[0003] Dimensional deviations may occur in thermoformed parts during production, affecting their assembly accuracy with other components. Inspection ensures that the dimensions of thermoformed parts meet the OEM's requirements for edge precision and assembly accuracy, preventing assembly difficulties or impacts on overall vehicle performance due to dimensional issues. To stably secure the thermoformed parts and prevent displacement or movement during inspection, ensuring accurate results, fixtures are used to clamp and fix the automotive thermoformed parts for testing.

[0004] Common fixtures only clamp and fix the two ends of automotive thermoformed parts, and then use inspection tools for inspection. However, it is inconvenient to place the uneven automotive thermoformed parts stably on the top of the workbench for clamping. Therefore, an automotive thermoformed part inspection fixture is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution: a testing fixture for automotive thermoformed parts. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 ,include:

[0029] The base frame 1 has a worktable 2 at its upper end and an electromagnetic ring 15 evenly distributed in a rectangular array at its lower end.

[0030] A stainless steel inner rod 13 is located inside the upper end of the electromagnetic ring 15, and the stainless steel inner rod 13 extends through and to the upper end of the workbench 2. A bottom tube 12 is provided inside the base frame 1 at the lower end of the electromagnetic ring 15. The stainless steel inner rod 13 is slidably connected to the bottom tube 12. A return spring 14 is installed at the lower end of the stainless steel inner rod 13 inside the bottom tube 12.

[0031] Side plates 3 are located on the outer sides of the workbench 2. Servo motors 5 are installed on both sides of the front end of the workbench 2 inside the side plates 3. Drive screws 6 are installed at the output end of the servo motors 5.

[0032] The slide 7 is slidably mounted on both sides of the upper end of the worktable 2, and the slide 7 is connected to the drive screw 6 by a threaded connection;

[0033] The slide bar 4 is located at the inner rear end of the side plate 3, and the slide frame 7 is slidably connected to the slide bar 4;

[0034] Clamping plate 8 is located at the upper end of carriage 7.

[0035] Please see Figure 1 and Figure 2 The front end of the worktable 2 is provided with a scale 9, and the scale 9 is integrally formed with the worktable 2. The scale 9 is used to intuitively detect the size of automotive thermoformed parts.

[0036] Please see Figure 1 The upper end of the clamping plate 8 is provided with a slot 17, and the slot 17 is integrally formed with the clamping plate 8.

[0037] Please see Figure 2 An extension plate 10 is provided at the upper end of the clamping plate 8, and the lower end of the extension plate 10 is adapted to the slot 17. The slot 17 is used for the insertion and installation of the clamping plate 8.

[0038] Please see Figure 2 A fixing bolt 11 is provided on one side of the lower outer end of the extension plate 10, and the fixing bolt 11 passes through the extension plate 10 and extends into the interior of the clamping plate 8. The fixing bolt 11 is used to fix the extension plate 10.

[0039] Please see Figure 2 An extension rod 16 is provided at the upper end of the stainless steel inner rod 13, and the extension rod 16 is connected to the stainless steel inner rod 13 by a threaded connection. The extension rod 16 is used to increase the height of the stainless steel inner rod 13 so as to adapt to automotive thermoformed parts with different bottom shapes.

[0040] This solution involves: closing the electromagnetic ring 15, thus eliminating the magnetic fixation of the stainless steel inner rod 13; then placing the automotive thermoformed part to be clamped on the upper end of the worktable 2 and applying downward pressure; the automotive thermoformed part contacts and is pressed down on the stainless steel inner rod 13, causing the stainless steel inner rod 13 to be forced downward and compress the return spring 14; the return spring 14 is compressed and deformed, and the stainless steel inner rod 13 retracts into the bottom tube 12; multiple stainless steel inner rods 13 extend and retract differently according to the shape of the bottom of the automotive thermoformed part; the stainless steel inner rods located within the outer range of the automotive thermoformed part... After the automotive part is placed, rod 13 is removed to prevent it from obstructing the movement of carriage 7. Then, electromagnetic ring 15 is activated to fix the stainless steel inner rod 13 by magnetic force. Servo motor 5 is started to control the rotation of drive screw 6. Under the threaded engagement of carriage 7 and drive screw 6 and the sliding connection between carriage 7 and slide rod 4, the rotational motion of drive screw 6 is converted into linear motion of carriage 7, thereby causing clamping plate 8 to clamp automotive part. The scale 9 is used to directly observe the positional changes of carriage 7 and scale 9, which facilitates the detection of the dimensions of automotive part.
