Abstract

连杆是连接活塞和曲轴，并将活塞所受作用力传给曲轴，将活塞的往复运动转变为曲轴的旋转运动。连杆组由连杆体、连杆大头盖、连杆小头衬套、连杆大头轴瓦和连杆螺栓（或螺钉）等组成。连杆组承受活塞销传来的气体作用力及其本身摆动和活塞组往复惯性力的作用，这些力的大小和方向都是周期性变化的。因此连杆受到压缩、拉伸等交变载荷作用。连杆必须有足够的疲劳强度和结构刚度。疲劳强度不足，往往会造成连杆体或连杆螺栓断裂，进而产生整机破坏的重大事故。若刚度不足，则会造成杆体弯曲变形及连杆大头的失圆变形，导致活塞、汽缸、轴承和曲柄销等的偏磨。本发明提供一种连杆铣端面，孔珩磨的加工。由1，底板；2，固定V型块；3，油缸；4，活动V型块；5，压紧螺钉；6，垫片；7，螺母；8，防滑垫组成。

Description

一种连杆专用工装
技术领域
连杆类零件是机械加工领域常见零件，尤其是发动机生产企业，一般都使用专用工装，本发明可以在一定范围适用不同长度的连杆加工。
背景技术
连杆是连接活塞和曲轴，并将活塞所受作用力传给曲轴，将活塞的往复运动转变为曲轴的旋转运动。连杆组由连杆体、连杆大头盖、连杆小头衬套、连杆大头轴瓦和连杆螺栓（或螺钉）等组成。连杆组承受活塞销传来的气体作用力及其本身摆动和活塞组往复惯性力的作用，这些力的大小和方向都是周期性变化的。因此连杆受到压缩、拉伸等交变载荷作用。连杆必须有足够的疲劳强度和结构刚度。疲劳强度不足，往往会造成连杆体或连杆螺栓断裂，进而产生整机破坏的重大事故。若刚度不足，则会造成杆体弯曲变形及连杆大头的失圆变形，导致活塞、汽缸、轴承和曲柄销等的偏磨。
发明内容
本发明解决以上不足，由1，底板；2，固定V型块；3，油缸；4，活动V型块；5，压紧螺钉；6，垫片；7，螺母；8，防滑垫组成，具有点位精度好，操作方便的特点，可以实现连杆端面铣削，孔的珩磨。
方案实施说明：
实施例1：根据连杆长度调整好活动V型块的距离，将工件安装到工装上，把压紧螺钉调整到合适的高度，启动液压站，按下压紧按钮，油缸做出相应动作，压紧工件，完成加工后，松开压板取下工件。
附图说明：
1，底板；2，固定V型块；3，油缸；4，活动V型块；5，压紧螺钉；6，垫片；7，螺母；8，防滑垫。
图1是一种连杆专用工装装配简图。
