Technical Field

[0001] The utility model relates to the technical field of middle groove marking tooling, in particular to a middle groove side processing marking tooling for a scraper conveyor. Background Art

[0002] The middle groove is the main mass-produced component of the scraper conveyor. During the production process, the assembly and welding of the middle groove occupies most of the time of the entire scraper conveyor production. The processing of the middle groove mainly includes the groove side, middle plate, bottom plate, etc. Among them, the groove side is a casting and is the basic component of the middle groove. When the middle groove is assembled and welded, it is necessary to position it with the two ends and the upper surface of the groove side to ensure the uniformity of the overall welding size. The requirements for the various positions and sizes of the parts are relatively strict. The marking of the groove side of the middle groove is to determine the processing allowance of the workpiece so that the processing has a clear size limit.

[0003] At present, in daily production processes, a method of manually marking and locating processing lines by using a ruler for leveling and alignment is adopted. However, in daily work, when encountering irregularly shaped workpieces, after encountering protrusions, it is necessary to re-level and align the groove side where the subsequent marking positions are required, which is rather cumbersome.
