Description

Technical Field

[0001] The utility model relates to the technical field of marking devices, in particular to a portable device suitable for adjusting the marking height of parts. Background Art

[0002] The marking process is a very important preparatory step in the machining and manufacturing process. Its main purpose is to analyze and adjust the product's appearance, mark the critical dimensional lines such as boundaries and positions required for subsequent processing on the workpiece surface, and realize the processing of the workpiece. For some medium and large castings with uneven surfaces and deformation of the workpiece itself, it is necessary to refer to the center line of the workpiece itself when marking, and take into account other relevant dimensions of the workpiece. When marking such products, our common method is to place the workpiece flat on a high block such as a marking platform. Subsequently, according to the center of the workpiece, the horizontal state of the workpiece is adjusted by adjusting the jacks at the four corners of the workpiece to achieve the purpose of correctly marking the horizontal center line of the workpiece.

[0003] The current operating process of using a jack to adjust the horizontal position of the workpiece has the following disadvantages: the jack adjusts the height in pitch mode, that is, each time it is pressed down, the jack lifts the workpiece by Lmm. For the case where the lifting height is ≤ Lmm, it cannot meet the requirements, resulting in poor marking accuracy; at the same time, the jack mainly uses the lever principle, that is, the long arm pries the short arm with a small force. For some operating scenarios with limited operating space, the pry bar cannot be used, which limits the use of the jack. So far, we have proposed a portable device suitable for adjusting the marking height of parts. Utility Model Content
