摘要：

本文是设计了一种车床用碟形弹簧做动力时弹簧夹头夹紧及松开机构。该

机构主要由弹簧夹头、拉杆、碟形弹簧、气动三联件等几部分组成。工作原理

主要是通过螺母套对碟形弹簧施加一定的轴向力，碟形弹簧安装在拉杆上，间

接对拉杆产生推动力推动推承套向右移动，推成套装配在弹簧夹头上，湖北鼎诚精密机械有限公司天博A股：2024年机床工具上市公司龙头名单牢记这些！（3月7日）弹簧夹

头与法兰相接触，利用推承套上的锥度形状将轴向力转换成径向力，使弹簧夹

头产生夹紧力对工件实现夹紧。再通过气动三联件对气缸活塞杆产生推

而活塞杆与拉杆通过拨块相连接，所产生的推动力大于螺母套施加的力，拉杆

得以向左移动，推承套失去推动力与弹簧夹头分离，弹簧夹头实现对工件的松

开。

而本次设计的夹具与以往的卡爪式夹紧松开机构相比较，拥有更好的平衡

性能、夹紧牢靠、结构紧凑、便于操作、加工及更换方便等主要优点。在主轴

高速旋转的情况下，也能达到需要的平衡要求。是高效率和良好精度特点的现

代车床夹具，可以有效地减少时间基本和配套工件加工的时间，大大提高了劳

Title Design Control collet chuck clamping and release

mechanism is in a lathe powered by a conical spring

Abstract

This article is designed to do when one kind of lathe with power disc spring collet

chuck clamping and release mechanism. The agency consists of several parts collets,

rod, disc springs, pneumatic FRL and other components. Works mainly on the disc

springs exert a certain axial force through the nut sleeve, disc springs mounted on

the rod, the rod indirectly generate driving force pushing the push bearing sleeve

moves to the right, push the spring clip assembly head sets, sp

with the flange using push bearing sleeve taper shape of the axial force is converted

into a radial force, so that collet chuck generate clamping force on the workpiece

clamping realization. And then the driving force generated by the cylinder piston rod

pneumatic FRL, and the piston rod and the rod is connected by dialing block, the

driving force is greater than the force exerted by the nut sleeve, lever to move to the

left, push the bearing sleeve lose impetus with the spring chuck separation collets

achieve workpiece release.

The design of the fixture and conventional jaw clamp release mechanism compared

with a better balance of performance, clam
