Description

角度可调夹紧装置
技术领域
   本发明涉及机械加工技术,具体涉及一种角度可调夹紧装置。
背景技术
   对轴类工件的加工制造需要轴类专用的夹紧装置对其夹持定位,目前,轴类工件的钻孔等加工工序采用的夹紧装置往往存在以下问题:需要对轴类工件沿周向多个角度进行钻孔或其他加工操作时,由于夹紧装置不能调节夹持角度,或者调节角度的结构较复杂,给操作带来不便,降低加工效率。
发明内容
本发明提供一种角度可调夹紧装置,以解决现有夹紧装置不便于调节工件夹持角度的问题。
为了解决上述技术问题,本发明采用如下技术方案:
角度可调夹紧装置,包括机架和具有中空筒状夹持部的夹具本体,夹持部的表面设有一层涨紧层,沿夹具本体周向设有多个卡齿,夹具本体的相对侧向分别设有可与所述卡齿卡合的定位销,夹具本体上固定连接有一导杆,所述导杆端部设有滑块,所述滑块设置在曲率与夹持部曲率相同的滑槽内,所述滑槽设在机架上。
本夹紧装置工作原理:将轴类工件置入夹具本体的夹持部,加工时通过设置在夹持部表面的涨紧层紧固工件,防止工件翻转,然后通过气缸或其他施力机构带动夹具本体两侧的定位销相对运动直至与卡齿卡合,定位工件加工的位置,一次加工完毕,需要转变角度加工工件时,松开两个定位销,在滑槽内移动设置在导杆端部的滑块,使导杆转过一定角度,由于导杆与夹具本体是固定连接的,因此夹具本体也转过相应的角度,此时再次使两个定位销与卡齿卡合定位工件,即可对工件进行不同角度的加工。由上可知,本夹紧装置可实现工件不同角度的夹持定位,且结构简单,操作方便。
进一步,在所述两个定位销的侧向均设有防翻转定位块。放翻转定位块也防止定位销在定位夹持时转动,以影响夹持定位的稳定性。
附图说明
图1是本发明角度可调夹紧装置实施例的结构示意图。
具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细的说明:
如图1所示的角度可调夹紧装置,包括具有中空筒状夹持部的夹具本体1,夹持部的表面设有一层涨紧层2,沿夹具本体1周向设有十个卡齿3,夹具本体1的相对侧向分别设有可与卡齿卡合的两个定位销4,在两个定位销的侧向均设有防翻转定位块9,夹具本体1上固定连接有一导杆5,导杆5端部设有滑块6,滑块6设置在曲率与夹持部曲率相同的滑槽7内,滑槽7设置在固定的操作台8上。上述涨紧层材料为聚四氟材料,具有加热膨胀涨紧的作用。对于长度较长的轴类工件,本实施例所述夹具本体、定位销、导杆、滑块和操作台可设置两组,分别夹持在工件的两端部,以保证夹持力度的均衡和夹持的稳定,提高工件加工的精度。
