Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal part detection, in particular to a detection tool for sheet metal stretching holes. Background Art

[0002] As a very common type of hole in automotive interior parts, special-shaped holes (including non-circular holes such as rectangular holes and waist-shaped holes) have an internal structure that directly affects whether the part can be stably installed during installation. If the internal structure fails the test, the part will be loose after installation, resulting in abnormal noises during the daily use of the vehicle. In addition, the external structure of the special-shaped hole directly affects the aesthetic appearance of the part and whether it can be tightly combined with the decorative parts installed on the special-shaped hole. Therefore, it is necessary to detect the special-shaped holes before the parts leave the factory. The existing detectors are usually fixed structures that cannot be adjusted, resulting in operators being unable to adjust the detector to a form suitable for their own operating habits, leading to different work efficiencies for each operator. Summary of the Utility Model

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific situations.

[0022] In one embodiment of the present utility model, as Figures 1 to 4 shown, a sheet metal stretching hole detection tooling is provided, including a holding part 1 and a detection part 2. An installation part 3 extends upward from the top of the holding part 1, and the installation part 3 is rotationally matched with the detection part 2. The detection part 2 includes a detection head 21 and a limiting column 22 arranged around the side of the detection head 21.

[0023] Furthermore, a limiting platform 11 is further provided at the top of the holding part 1, and the installation part 3 extends upward from the top of the holding part 1 and passes through the limiting platform 11. An installation hole 23 is recessed inward at the bottom of the detection part 2 for realizing rotational matching with the installation part 3. Specifically, when installing the detection part 2, the installation part 3 is inserted into the installation hole 23 of the detection part 2 until the bottom of the detection part 2 abuts against the top surface of the limiting platform 11.

[0024] Further, the mounting hole 23 is provided with threads, and the mounting portion 3 is threadedly connected to the threads in the mounting hole 23. Specifically, in this embodiment, providing threads in the mounting hole 23 can adjust the working attitude of the detection portion 2 by rotation, and at the same time, the distance between the detection portion 2 and the limiting platform 11 can also be adjusted by rotating the detection portion 2, which can better adapt to the usage habits of operators, thereby improving production efficiency; by threadedly connecting the detection portion 2 to the mounting portion 3 through the threads in the mounting hole 23, the detection portion 2 can be rotated at most to the position where the bottom abuts against the top of the limiting platform 11. At this time, the operator can then rotate the detection portion 2 in the reverse direction to adjust the working attitude of the detection portion 2 and the distance between the detection portion 2 and the limiting platform 11.

[0025] Further, the mounting portion 3 includes a fixed rod 31 and a rotating portion 32. The rotating portion 32 is rotatably connected to the fixed rod 31, and the outer side of the rotating portion 32 is in interference fit with the inside of the mounting hole 23. Specifically, different from the above-mentioned embodiment, in this embodiment, when the mounting portion 3 is fixedly installed in the mounting hole 23, the rotating portion 32 is inserted into the mounting hole 23. The outer side of the rotating portion 32 can be made of a material with good elasticity, such as silicone. After the rotating portion 32 is inserted into the mounting hole 23, an interference fit effect with the inside of the mounting hole 23 can be achieved, improving the stability between the rotating portion 32 and the inside of the mounting hole 23. When the operator rotates the detection portion 2, the detection portion 2 drives the rotating portion 32 to rotate in cooperation with the fixed rod 31. The way of rotating cooperation between the fixed rod 31 and the rotating portion 32 can be thread fit. By setting the way of threaded connection between the fixed rod 31 and the rotating portion 32, the rotation effect can be achieved, or it can be other solutions in the prior art to realize the rotational connection between the fixed rod 31 and the rotating portion 32.

[0026] Further, a detection surface 211 is provided on the top surface of the detection head 21. Specifically, when the detection portion 2 completely passes through the stretching hole 4, and the bottom edge of the stretching hole 4 is in limit fit with the top of the limiting column 22, the top surface of the stretching hole 4 should be flush with the detection surface 211 at this time. By providing the detection surface 211, it can cooperate with the limiting column 22 to measure the height from the bottom to the top of the stretching hole 4, thereby achieving a better detection effect.

[0027] Working principle: The holding part 1 is grasped by hand. The holding part 1 can be a ring-shaped structure that fits over the operator's finger or a rod-shaped structure that is clamped between the operator's fingers. During use, the detection part 2 is inserted into the stretching hole 4 of the sheet metal part. When the detection part 2 can completely pass through the stretching hole 4 and the bottom edge of the stretching hole 4 is in limit fit with the top of the limit post 22, the sheet metal part is qualified; by setting the mounting part 3 to be rotationally matched with the detection part 2, after the operator grasps the holding part 1, by twisting the detection part 2 and rotating the detection part 2 to an appropriate angle, it is convenient to better suit the usage habits of each operator, thereby improving the detection efficiency.
