[0027] The present invention will be further described in detail below with reference to the accompanying drawings. The description is intended to explain the present invention and not to limit it.

[0028] Example 1 See Figures 1-3A thickness measuring fixture for plate-type parts includes a fixed base 1, a measuring worktable 2, a support column 3, a U-shaped support assembly 4, a dial indicator universal length measuring tool 5, a first fastening assembly 6, and a second fastening assembly 7; the dial indicator universal length measuring tool 5 includes a dial indicator body 51, a sleeve 52, and a probe 53 connected sequentially from top to bottom; Among them, the U-shaped support component 4 is set above the fixed base 1 and the open end of the U-shaped support component 4 is perpendicular to the ground. The measuring workbench 2 is connected to the support column 3. The bottom of the support column 3 passes through the lower part of the U-shaped support component 4 and connects to the fixed base 1. One end of the sleeve 52 passes through the upper part of the U-shaped support component 4. During measurement, the first fastening component 6 is horizontally inserted into the lower side of the U-shaped support component 4 to fasten the measuring workbench 2, and the second fastening component 7 is horizontally inserted into the upper side of the U-shaped support component 4 to fasten the dial indicator universal length measuring tool 5.

[0029] The measuring fixture provided by this invention can reduce the misjudgment rate and improve the accuracy of the testing process. The entire measuring system forms a robust rigid frame through support columns and U-shaped support components, which has strong resistance to vibration interference and eliminates errors caused by unstable human force and posture during manual measurement. The first and second fastening components ensure that the measuring workbench and gauge are absolutely stable during the measurement process, providing a stable measurement benchmark and ensuring that different batches and different operators can obtain consistent measurement conditions, thus ensuring the accuracy and repeatability of each measurement data and the reliability of the measurement results.

[0030] Specifically, the measuring workbench 2 is connected to the support column 3 by welding or threading.

[0031] Specifically, the fixed base 1 includes a magnetic measuring platform and a magnetic suction base connected sequentially from top to bottom. The magnetic suction base can quickly and firmly attach the entire fixture to the metal worktable, ensuring the stability of the measurement process; while the magnetic measuring platform can quickly attach and fix the metal plate parts to be measured, saving tedious clamping time. The operator only needs to place the part on the platform and tighten it to read the value, realizing "immediate measurement upon placement", thereby improving the detection efficiency.

[0032] Specifically, the magnetic measurement platform is connected to the bottom of the support column 3 via a threaded connection.

[0033] Specifically, the magnetic measurement platform is connected to the bottom of the support column 3 by welding.

[0034] Specifically, the dial-type general length measuring tool 5 also includes a handle 54, which is disposed on the dial body 51.

[0035] Specifically, the U-shaped support component 4 is a curved beam.

[0036] Specifically, the general-purpose length measuring tool 5 is a dial indicator.

[0037] Specifically, the general-purpose length measuring tool 5 is a dial indicator. The accuracy of a dial indicator can reach 0.001 mm, which is far higher than that of conventional calipers, providing a hardware foundation for high-precision measurement.

[0038] Specifically, both the first fastening component 6 and the second fastening component 7 are fastening bolts.

[0039] In a specific embodiment of this utility model, a thickness measuring fixture for plate-like parts includes a magnetic measuring platform, a magnetic base, a knob, a support rod, a measuring worktable 2, a bending beam, a dial indicator, a dial indicator probe 53, a handle 54, and fastening bolts. During measurement, the dial indicator probe 53 is first placed firmly against the measuring worktable 2, and the dial indicator pointer is adjusted to zero. Then, the lower end of the part to be measured is placed horizontally against the measuring worktable 2, with the dial indicator probe 53 firmly against the upper end of the part. The thickness of the part is directly read from the dial indicator. The magnetic base is magnetically fixed to the magnetic measuring platform using the knob. The lower end of the support is connected to the magnetic base by a thread or by welding. The upper end of the support is connected to the measuring workbench 2 by thread or welding; the support passes through the lower end of the curved beam and is fixed with fastening bolts; the dial indicator passes through the upper end of the curved beam and is fixed with fastening bolts; the handle 54 is lifted upwards, causing the internal rack pointer of the dial indicator to deflect, and the dial indicator probe 53 moves up and down with the handle 54.

[0040] During measurement, adjust the position of the sleeve 52 passing through the upper part of the bending beam according to the thickness of the plate-like part to be measured. After adjustment, fix the sleeve 52 of the dial indicator to the bending beam with the fastening bolts. Press the dial indicator down so that the probe 53 of the dial indicator is in close contact with the upper surface of the measuring worktable 2. At this time, zero the dial indicator.

[0041] After zeroing the dial indicator, place the plate-like part to be measured on the upper surface of the measuring worktable 2, press the dial indicator down so that the probe 53 of the dial indicator is in close contact with the upper surface of the plate-like part, and read the value of the dial indicator, which is the thickness of the plate-like part.

[0042] Finally, it should be noted that the embodiments listed above are merely one or more specific manifestations of the technical solution of this utility model. Their purpose is to clearly illustrate the concept, principle, and application of this utility model through specific examples, and is by no means intended to limit the scope of protection of this utility model to these specific embodiments. In fact, the true value of this utility model lies in its proposed technical ideas and innovations, rather than its manifestations or implementation methods.

[0043] For those skilled in the art, after thoroughly reading and understanding the technical solution of this utility model, they are fully capable of making various changes, modifications, or equivalent substitutions to the specific embodiments of the utility model based on their own professional knowledge and skills. These changes may include, but are not limited to: adjusting the range of technical parameters, optimizing the algorithm flow to improve efficiency, and replacing some technical components to achieve better compatibility or reduce costs. As long as these modified technical solutions substantially retain the technical features claimed by the original utility model, that is, they can still achieve the core functions and effects of this utility model, then these changes should be considered to fall within the scope of protection of the pending claims of this utility model.

[0044] Furthermore, with the continuous progress and development of technology, new technical means and methods are constantly emerging, which provides ample space for the further improvement and perfection of this utility model. Therefore, the scope of protection of this utility model should also include reasonable and foresightful improvements and extensions based on existing technology.
