Embodiment 1

[0037] Such as figure 1 , figure 2 , image 3 As shown, a machine tool integrated transmission box includes:

[0038] An integrated transmission box for a machine tool, comprising:

[0039] Transmission box 9, torque clutch 14 and forward and reverse non-constant speed output gear set;

[0040] The positive and negative non-constant speed output gear set is provided with a drive shaft 3 for torque input and a driven shaft 6 for output torque, as well as a reverse drive gear 2, a feed drive gear 4, a reverse drive gear 5 and a feed drive gear 7;

[0041] The drive shaft 3 is in transmission connection with the power system 1 of the machine tool.

[0042] A torque clutch 14 is also provided between the driven shaft 6 and the execution device 8 of the machine tool; the torque clutch 14 includes a power input shaft 22 and a power output shaft 27;

[0043] The reverse driven gear 5 and the forward driven gear 7 are coaxially connected to the driven shaft 6, the driven shaft ...

Embodiment 2

[0059] The rest are the same as in Embodiment 1, except that the machine tool anti-pinch device is also provided with a sensor for detecting torque, the angle of rotation of the torque output slider 6 or the position of the torque output slider 6, and the sensor is connected to the electric power system. connect. When an obstacle is encountered, the sensor detects a relevant variable, controls the power system 1 to reverse, and makes the actuator 8 retreat to facilitate troubleshooting.

Abstract

The invention discloses a machine tool integrated transmission box which adopts two sets of one-way transmission devices with opposite directions and can realize rapid back and slow feeding of a machine tool through a simple structure as well as has the advantages of simple structure, low cost, and low failure rate and maintenance cost and ensures that the whole transmission box can integrally complete the requirement of output at different rotating speeds of mechanical positive rotation and mechanical negative rotation. Meanwhile, a torsion clutch is arranged between a power system of the machine tool and an executing device of the machine tool, so that when the machine tool is blocked during feeding, the torque on a transmission shaft is increased, finally the torsion clutch is tripped, the machine tool maintains a harmless clamping force, and the motor can not be blocked and burnt, therefore, a control circuit is matched for controlling the motor to negatively rotate and retreat. The machine tool integrated transmission box is a mechanical blockage-preventing device, and has the advantages of simple structure, low cost, low failure rate, safety and reliability.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a machine tool integrated transmission box. Background technique [0002] Machine tools generally require fast retreat and slow feed to meet the requirements of high retreat efficiency and high feed safety factor. At present, machine tools generally use a set of reduction gear boxes with forward and reverse constant speed output. The motor connected to it In the case of the same speed, the output speed and torque are the same. In order to realize fast retreat and slow feed, the speed regulation generally adopts the motor speed control system or the clutch to switch gears with different speed ratios to realize retreat and feed. The above-mentioned system has the disadvantages of complex structure of the control system, high cost, high failure rate, and high maintenance cost. At the same time, the function of its mechanical transmission device is single, and it cannot be integrated to...
