Movement mechanism used for drawing center line

Abstract

The invention provides a movement mechanism used for drawing a center line. The movement mechanism comprises a handle, an end cover, a rolling shaft lead screw, a sliding seat, a sliding rail, a firstrotating rod, large rolling wheel shafts, large rolling wheels, small locating blocks, a square workpiece, a pen, a second rotating rod, small rolling wheel supports, small rolling wheels, small rolling wheel shafts, telescopic steering rods and the like. The movement mechanism is characterized in that the handle is mounted at one end of the rolling shaft lead screw through a thread; the slidingseat is fixedly mounted on the rolling shaft lead screw; the large rolling wheels are mounted on the two sides of the sliding rail and the two sides of the sliding seat through threads correspondingly; the two rotating rods are in bolted connection; the small locating blocks are fixedly mounted in grooves of the rotating rods; the telescopic steering rods are mounted on the small locating blocks through threads; the small rolling wheel supports are fixedly mounted on the telescopic steering rods through threads; and the small rolling wheels are rotationally mounted in holes in the lower sidesof the small rolling wheel supports. The movement mechanism is simple in structure and good in manufacturing manufacturability, the work efficiency of the center line can be improved, movement on a workpiece can be achieved, and the work of the center line can be finished well.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, in particular to a moving mechanism for drawing a centerline. Background technique [0002] As we all know, drawing the processing boundary on the workpiece according to the requirements of the drawing is called scribing. Scribing work is an important link in machining. Commonly used scribing tools are scribing platforms, height gauges, scribing needles, etc., but the commonly used tools sometimes cannot meet the requirements of some scribing work, and need to use other equipment or special tooling to complete. [0003] For example, due to various factors such as manufacturing errors of large workpieces, the center line is sometimes drawn inaccurately, which affects the determination of the center of the entire assembly during final assembly. Therefore, it is necessary to send people to adjust many times, resulting in waste of manpower and material resources, and also seriously af...
