Technical Field
[0001] This utility model relates to the field of tooling and testing technology, and in particular to a rapid testing tooling for upper guard plate products. Background Technology
[0002] Upper guard plates, typically used as protective components for machinery, equipment, or vehicles, require tooling or equipment for assembling, securing, or protecting them. To ensure that the quality of the upper guard plates and their tooling meets design requirements and safety standards, a series of rigorous tests must be conducted.
[0003] In the current process of inspecting the upper guard plate, operators need to use manual tools such as calipers and micrometers to measure point by point. Therefore, the upper guard plate needs to be clamped on a special platform, and appearance defects are inspected visually. This method is acceptable for single-piece inspection, but it exposes many problems in batch inspection: low inspection efficiency, unstable measurement accuracy, and poor result repeatability, which limits production speed.

[0007] As a further improvement of this utility model, the support mechanism includes a first support column disposed above the base, and the upper end of the base is provided with a first insertion hole that matches the size of the first support column, and the first support column is inserted into the first insertion hole.
[0008] As a further improvement of this utility model, the second support mechanism includes a second support column disposed above the base, and the upper end of the base is provided with a third insertion hole that matches the size of the second support column, and the second support column is inserted into the third insertion hole.
[0009] As a further improvement of this utility model, a third support column is provided on both sides of the second support column, and two second insertion holes are opened at the upper end of the base that match the size and position of the third support column. The two third support columns are respectively inserted into the two second insertion holes.
[0010] As a further improvement of this utility model, the lower end of the base is provided with five threaded grooves, which correspond to the positions of two first insertion holes, two second insertion holes and a third insertion hole respectively. Each threaded groove is threaded with a bolt, and the base is fixedly connected to two first support columns, two third support columns and a second support column respectively by multiple bolts.
[0011] As a further improvement of this utility model, the upper ends of the two first support columns and the second support column are fixedly connected with protrusions, and the protrusions are used to limit the position of the guard plate workpiece.
[0012] The beneficial effects of this utility model are:
[0013] By setting up support mechanism one and support mechanism two, the guard plate workpiece can be quickly and securely fixed on the dedicated platform, reducing errors and time consumption caused by manual fixing operations. At the same time, the protrusion design ensures the stability and accuracy of the guard plate workpiece during the inspection process, thereby improving the consistency and reliability of the inspection results and making batch inspection more efficient and accurate.
[0014] This invention optimizes the fixed process and uses an external testing instrument, enabling the guard plate workpiece to be quickly and stably positioned and automatically complete multi-segment fixed-point scanning, reducing manual errors, ensuring stable and accurate testing, and significantly improving the efficiency and reliability of batch testing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Figures 1-7 A rapid testing fixture for upper protective plate products includes a base 1, with a protective plate workpiece 6 positioned above the base 1. A through-hole 5 for securing the workpiece 6 is provided in the center of the base 1. The base 1 can be stably installed at the testing location via this through-hole 5, ensuring that the protective plate workpiece 6 does not shift during testing. Support mechanisms are connected between the two ends of the protective plate workpiece 6 and the base 1. Two support mechanisms are used to fix the two ends of the protective plate workpiece 6. Each support mechanism includes a first support column 2 positioned above the base 1, supporting the two ends of the protective plate workpiece 6. A section of the base 1, approximately the same size as the first support column 2, is provided at the upper end. The first insertion hole 9 is connected to the first support column 2, which not only provides good support but also simplifies the assembly process of the device and improves work efficiency. The middle part of the guard plate workpiece 6 is connected to the base 1 by a second support mechanism. The second support mechanism is used to support the middle part of the guard plate workpiece 6. The second support mechanism includes a second support column 3 set above the base 1. The upper end of the base 1 is provided with a third insertion hole 11 that matches the size of the second support column 3. The second support column 3 is inserted into the third insertion hole 11, which ensures that the guard plate workpiece 6 can be evenly supported throughout its entire length, avoiding deformation or damage due to uneven local force.
[0025] Both sides of the second support column 3 are provided with third support columns 4. The upper end of the base 1 has two second insertion holes 10 that match the size and position of the third support columns 4. The two third support columns 4 are respectively inserted into the two second insertion holes 10. The function of the third support columns 4 is to further enhance the stability of the middle area of the guard plate workpiece 6 and prevent unnecessary shaking or displacement during the inspection process. The lower end of the base 1 has five threaded grooves 7. The five threaded grooves 7 correspond to the positions of the two first insertion holes 9, the two second insertion holes 10 and the third insertion hole 11 respectively. Each threaded groove 7 is threaded with a bolt 8. The base 1 is fixedly connected to the two first support columns 2, the two third support columns 4, and the second support column 3 by multiple bolts 8, ensuring a firm connection between all the first support columns 2, the second support columns 3, and the third support columns 4 and the base 1. This makes the entire device more stable and reliable, suitable for various working environments. The upper ends of the two first support columns 2 and the second support columns 3 are fixedly connected with protrusions 12. Multiple protrusions 12 are used to limit the position of the guard plate workpiece 6, which helps to quickly position and install the guard plate workpiece 6, and can also effectively prevent it from slipping or shifting during the testing process, ensuring the accuracy of the test results.
[0026] When using this utility model, the worker places both ends of the protective plate workpiece 6 on the upper ends of the two first support columns 2, and inserts it into the two protrusions 12 on the two first support columns 2 through the holes and slots on the protective plate workpiece 6. Then, it inserts it into the protrusion 12 on the upper end of the second support column 3 through another hole and slot, thereby limiting the protective plate workpiece 6 on the device. Subsequently, the protective plate workpiece 6 is scanned at multiple points by an external instrument to determine whether the protective plate workpiece 6 meets the product qualification requirements.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
