Design of a New-style Escort Mechanism of Vertical Internal Broaching Machine

In an effort to improve the property of escort mechanism of vertical internal broaching machine, a new-style escort mechanism is designed. Work process and defect about structure of escort mechanism in existence is firstly analyzed in depth, design concept and implementation methods of the new escort mechanism are then studied. Three-dimensional structure and work process are presented, and performance comparison between the new-style structure and the old one is conducted. Application study is launched at last. The innovative escort mechanism and slide board are movably connected and lumped together. In consequence, the escort mechanism will stop and then be hung at the column, while the tool slide continues to move down until broaching stop. The new-style escort mechanism has superiority such as low cost, high robust and good safety, and so on, which make it adaptive and useful for structural optimization of broaching machine.
