Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a marking fixture. Background Technology

[0002] In existing technologies, engines have complex structures, consisting of four to five thousand parts, resulting in long production cycles and requiring multiple whole-machine tests, assembly, disassembly, and turnover. During these processes, to ensure the identifiability of all parts, most parts need to be numbered and managed (each part's serial number is managed individually). Some of these serial numbers and component identification numbers need to be marked on the surface of the parts using a marking device, becoming permanent identification marks. Because the marking requirements for many parts are very high, conventional marking involves placing the part directly on the marking machine's work platform, visually aligning the part's center roughly with the center of the rotating platform, pre-pressing the part with bolts through T-blocks on the rotating platform using pressure plates, and then using a dial indicator to calibrate the part's positioning surface and the marking fixture's positioning surface to achieve the required accuracy before marking. Existing fixtures typically involve placing the workpiece between two clamping plates, clamping it by bringing the two plates close together. However, when the workpiece is irregularly shaped, the clamping plates cannot be aligned for clamping. Utility Model Content
