#208 Design Image Training - 24: Design Drawing Method for Movable Body

Category : Hints on designing
July17, 2015

When designing machinery equipment containing a movable body, the designer needs to check in the early stages of the designing process that unforeseen problems do not occur throughout the moving range of the movable body. This section introduces the design technique for a movable body.

  • Two-dot chain lines (also called imaginary lines) are used for illustrating the operating state. Dashed lines (also called hidden lines) are used for illustrating invisible (hidden) structures.

  • Draw a two-dot chain line (imaginary line) to illustrate the maximum stroke position in the movable range when designing a movable body in the assembly diagram.
  • The designer must check that the condition of the movable body does not cause any structural problems at this maximum stroke position.
  • In the example of the Bingo Machine shown in [Fig.1], two-dot chain lines indicate the cable bearing state at the maximum stroke position of the X-axis table.
  • Based on the state of the two-dot chain lines in [Fig.1], you can verify the following:
    (1) It is designed with sufficient room that the cable bearing does not touch the cover even when the X-axis table moves to the leftmost position.
    (2) In the plan view seen from above (not [Fig.1]), the cable bearing does not get in the way of the manifold regulator of the air cylinder installed on the back.

  • [Fig.2] is an example of the submerged endurance test machine. The movable body is illustrated at two positions: left end (solid line) and right end (two-dot chain line).
