AI Technical Summary

Technical Problem

The existing automated assembly of the guide post assembly of the rack tensioner has problems such as tooling vibration interfering with assembly accuracy, interference caused by assembly timing coupling, insufficient height difference adaptation capability, and damage to parts caused by pressure impact.

Method used

It adopts a suspended assembly design and a division-of-labor gripper structure. The tooling is lifted by wedge blocks to isolate the impact of vibration. The division of labor design of cylinder gripper one and cylinder gripper two enables the precise placement of parts and independent operation of pins. At the same time, a dynamic height adjustment component is used to adapt to the assembly height requirements of different parts.

Benefits of technology

It improves assembly accuracy and stability, reduces defect rate and part damage rate, increases production efficiency and equipment flexibility, and adapts to the needs of multi-variety production.

Abstract

本发明公开了一种齿杆张紧器加工用压装一体组件,涉及张紧器组装加工技术领域,包括下机架,下机架的上方转动连接有分度转盘,分度转盘的外部装配有转盘工装固定板,导柱结构件位于转盘工装固定板的上方,下机架的上方装配有装导柱模块,装导柱模块包括气缸夹爪一和气缸夹爪二,装导柱模块的下方设置有工序顶升组件,工序顶升组件包括楔形块,通过新增工装支撑座顶起工装的独立动作,在装配前先将工装从分度转盘略微顶起,使工装完全脱离转盘运转间隙与振动影响,在悬浮状态下完成弹簧、导向柱、导柱、齿杆的装配,完善了传统固定工装因转盘振动导致的零件偏移问题,有效提升了导柱与壳体的同轴度,降低了偏载压装、零件卡滞等不良率。
