All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Reference Figure 1-4 Automotive dashboard metal frame calibration tooling, including

[0029] The base plate 1 is used to provide basic support for the entire tooling. In order to ensure the overall stability and load-bearing capacity of the tooling, the base plate 1 is made of high-strength steel.

[0030] The positioning and clamping structure 3 is set according to the positioning requirements of the metal frame assembly drawing of the automotive dashboard. It includes a positioning fixture, which works with a cylinder controlled by a hand lever valve 6 to position and clamp the metal frame. The positioning fixture in the positioning and clamping structure 3 fits into the metal frame through specific positioning holes and surfaces. In order to stably control the intake and exhaust of the cylinder, the hand lever valve 6 is a two-position five-way hand lever valve. To improve the response speed of the cylinder, a double-acting cylinder is adopted, which can provide greater clamping force and has the characteristics of fast response and stable operation. In addition, the positioning fixture in the positioning and clamping structure 3 can adopt a specially designed groove and protrusion structure to fit tightly with the corresponding parts on the metal frame, further improving the positioning accuracy.

[0031] The detection structure 2 includes a detection pin and a no-go gauge. The detection structure 2 is adjustable and is used to detect the required position of the metal frame. Since the detection structure 2 is adjustable, it can be adjusted according to different models of metal frames.

[0032] The flip-plate structure 4 can be flexibly flipped, facilitating operation and inspection of different parts of the metal frame. In order to maintain a fixed position after flipping, the flip-plate structure 4 is connected to the tooling body through a damping pivot. That is, the flip-plate structure 4 is connected to the tooling body through a high-strength hinge. The hinge is equipped with a damping device, which allows the flip-plate structure 4 to stop smoothly at any angle during the flipping process, making it convenient to operate. This design method makes it convenient for operators to operate and inspect different parts of the metal frame, improving the convenience and flexibility of tooling use.

[0033] The alignment tool 5 is used to correct the corresponding position when the detection structure 2 detects that the metal skeleton does not meet the requirements. In order to extend the service life of the alignment tool 5, the surface of the alignment tool 5 is treated with wear resistance.

[0034] In this embodiment, in order to facilitate the movement and position adjustment of the entire tooling, the bottom of the base plate 1 is provided with a hand-pushed trolley 7 structure, and the bottom of the hand-pushed trolley 7 uses universal wheels with self-locking function.

[0035] In actual use, the metal frame is first placed on the positioning and clamping structure 3 of the tooling, so that the positioning part of the metal frame is tightly matched with the groove and protrusion structure of the positioning fixture. Then, the cylinder in the positioning and clamping structure 3 is activated. The cylinder works to drive the positioning fixture to firmly clamp the metal frame.

[0036] Next, the operator uses the inspection pin and go / no-go gauge in inspection structure 2 to inspect the holes and surfaces of the metal frame that need to be inspected. If the inspection finds that a certain position does not meet the requirements, the operator can flip the flip plate structure 4 to expose the part that needs to be corrected in an easy-to-operate position, and then use the alignment tool 5 to correct the position. After the correction is completed, the inspection structure 2 is used again to inspect until all the inspection parts of the metal frame meet the requirements.

[0037] After completing the calibration work, shut off the cylinder, release the positioning fixture, and remove the calibrated metal frame from the tooling.

[0038] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0039] Working principle: When using this fixture, the positioning and clamping structure 3 first accurately positions and firmly clamps the metal frame to ensure its stable position during the calibration process. The detection structure 2 uses detection pins and go / no-go gauges to detect the metal frame and determine whether its dimensions meet the standards. When a non-compliant part is detected, the calibration tool 5 applies appropriate external force to the metal frame during the calibration process to restore it to the standard dimensions. The flipping function of the flipping structure 4 facilitates the operator to operate on different parts of the metal frame.
