一种夹紧气缸
本技术涉及气缸
,特别涉及一种夹紧气缸。
技术介绍
气缸一般是由缸体、端盖、活塞、活塞杆和密封件等部件组成。气缸是引导活塞在其中进行直线往复运动的圆筒形金属机件,将压缩空气的压力能转换为机械能,驱动机构作直线往复运动、摆动和旋转运动。目前气缸已广泛应用于印刷、半导体、自动化控制、机器人等多种领域。铣削加工时,切削力较大,又是断续切削,振动较大,因此铣床夹具的夹紧力要求较大,夹具刚度、强度要求都比较高。现有的铣床装夹工装,结构复杂,夹紧力较小,夹紧强度不足,造成铣削加工时振动大,加工精度不足。
技术实现思路
针对现有技术的不足和缺陷,提供一种夹紧气缸,结构简单,能够牢固夹紧待加工的工件。为实现上述目的,本技术提供以下技术方案。一种夹紧气缸,包括缸体和固定连接于缸体后端的后盖,缸体内设有容置腔,后盖上设有连通容置腔的进气孔,容置腔内设有活塞,活塞一侧与进气孔连通,活塞另一侧连接有推杆,推杆穿过缸体伸入容置腔内与活塞连接,活塞设有推杆的一侧还设有回复弹簧,回复弹簧一端与容置腔内壁相抵,回复弹簧的另一端与活塞相抵,缸体前端设有延伸块,延伸块向上凸出有挡块, ...
