The utility model relates to a locking device, including a handle, a press rod, a support, a lock tongue, a spring and a lock block. The lock tongue is two, and all of the two latches are set relative to the support seat, the opposite sides of the two latches are all inclined, that is, the two lock tongue forms the V slide Road, and the spring is used for two latch tongues. For the spring force, the two lock tongue is closed to each other; the lock block is arranged in the V slide Road, and can slide up and down in the V slide. When the lock slid to the lower part of the V slide, the spring force is overcome by the spring force to open the lock tongue and the two lock tongue is opened and kept on both sides. The screw hole is opened on the support and is matched with the screw thread. In addition, the lower end of the pressure bar is located above the lock block. When the pressure rod rotates and moves down, the lock block is pushed to the lower part of the V slide. When the bar moves up, the lock will move up the V slide and leave the lock position of the lower part of the V slide under the effect of the spring force. The device has the advantages of simple structure, convenient operation, strong usability and good locking effect.
【技术实现步骤摘要】
一种锁紧装置
本技术属于机加领域,涉及一种锁紧装置。
技术介绍
由于叉口件大部分是铸件,在对叉口工件进行精加工的过程中。由于悬臂较长,在对悬臂进行精加工的过程中,会出现加工时叉口振颤现象。为了防止加工过程中叉耳处发生振颤,在叉口处设计了一种用于防止振颤的夹紧装置。
技术实现思路
针对现有技术存在的不足,本技术提出一种从零件下部夹紧的装置。技术方案:提供一种锁紧装置,包括手柄1、压杆2、支座4、锁舌5、弹簧6和锁块7;所述锁舌5为两个,且均转动的连接到支座上,两个锁舌相对设置,两个锁舌相对的面均为斜面,即两个锁舌之间构成V型滑道;弹簧用于为两个锁舌提供弹簧力,使得两个锁舌相互靠拢;所述的锁块设置在V型滑道中,且能够在V型滑道中上下滑动,当锁块滑动到V型滑道下部时会克服弹簧力顶开两个锁舌,使得两个锁舌向两侧打开并保持;支座4上开有螺纹孔,并与压杆2螺纹配合,压杆2下端位于锁块上方,当压杆2旋转下移时会将锁块向V型滑道下部推动,当压杆2旋转上移时锁块会在弹簧力的作用下沿着V型滑道上移,离开V型滑道下部的锁定位置。进一步的,所述的锁块为球型、倒锥形或倒梯形。进一步的,所述的锁舌内 ...
