摘要
针对目前排线机构结构复杂,制造成本高,装配精度要求高、受冲击力大,易造成磨损等问题,设计了一种新型滑块式皮带排线机构。该机构通过减速电机驱动皮带运行,而皮带穿过排线导轮座的内孔,由于排线导轮座的内孔安装有内设有斜孔并能径向移动的止推块,通过气缸使斜形滑块在往复移动过程中,使止推块沿径向上下往复移动,从而使排线导轮座分别夹紧皮带的上边或下边,使皮带带动排线导轮座左右作往复运动。具有结构简单,制造精度高,制造成本低廉,换向时冲击力小等优点。
Specific to the problems available in the existing traversing mechanism,such as complex structures,high manufacturing costs,high precision requirement in assembly as well as huge impact force and easy to wear and so on,a new slider type belt traversing mechanism was designed,which belt is driven by a gear motor and traverse through the bore of cable guide pulley seat.Since a thrust block with inclined hole which is movable in radial direction is mounted at the bore of the pulley seat,the thrust block moves back and forth up and down in the reciprocating process of oblique slider driven by the cylinder,thus the pulley seat shall clamp respectively the upper side and lower side of the belt and move back and forth with the belt.The mechanism is characterized with its advantages of simple structure,high manufacturing precision as well as low manufacturing cost and less impact force in changing of direction.
