一种机床一体传动箱

Integrated transmission case of machine tool

Abstract

The utility model discloses an integrated transmission case of a machine tool. Two sets of opposite one-way transmission devices are adopted, quick retreating and slow feeding of the machine tool are realized through a simple structure, and a simple structure, low manufacturing cost, low failure rate and low maintenance cost are achieved. By adopting the entire transmission case, the requirement on output of different rotating speeds through positive and negative mechanical rotation can be completed integrally. Meanwhile, a torsion clutch is arranged between the power system of the machine tool and the executing device of the machine tool, so that torque on a transmission shaft is increased when feeding of the machine tool is blocked, the torsion clutch is released, the machine tool maintains a harmless clamping force, a motor is prevented from being locked or burnt down, and reverse rotation and retreating of the motor are controlled in match with a control circuit. The device is a mechanical anti-locking device, and has the advantages of simple structure, low manufacturing cost, low failure rate, safety and reliability.
本实用新型公开了一种机床一体传动箱,采用两套方向相反的单向传动装置,可以通过简单的结构实现机床的快速后退和慢速进给,结构简单,造价低,故障率和维修成本低。并使得整个传动箱可以一体化完成机械式正反转不同转速输出的要求。同时,在所述机床的动力系统与所述机床的执行装置之间设有扭力离合器,使得机床在进给受阻时,传动轴上的扭矩增大,最终使扭力离合器脱扣,机床维持无害的夹持力,并且电机不会堵转烧毁,此时配合控制电路控制电机反转后退,该装置是机械式防堵转装置,结构简单,造价低,故障率低和安全可靠。
