Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] The invention provides a servo turret tool holder overload protection device, which is located between the tool holder servo motor and the gear transmission system. When the tool holder is working normally, the device can effectively transmit the motor torque to the gear transmission system; when the machine tool crashes and other unexpected situations occur, the two ends of the mechanism will disengage in the circumferential direction, and the torque can no longer be transmitted, so that the servo motor Neither the gear train nor the gear train will be damaged due to excessive load. At the same time, when troubleshooting the tool post, only a simple operation of the overload protection device is required to restore the tool post to normal and put it into use again.

[0021] The protection device includes a driving side bushing 1, a steel ball 3, a stopper 6, a...

Abstract

The invention provides a servo turret head overload protection device. The protection device comprises a drive side shaft sleeve (1), a steel ball (3), a blocking block (6), a bearing (2), a spring (4), a driven side shaft sleeve (11), a bolt (12), a clamping sleeve (10) and a moving shaft sleeve (9), wherein one side of the driven side shaft sleeve (11) is connected with the drive side shaft sleeve (1), and the other side of the driven side shaft sleeve (11) is connected with the clamping sleeve (10); the bearing (2) is located between the drive side shaft sleeve (1) and the driven side shaft sleeve (11); the moving shaft sleeve (9) is located outside the driven side shaft sleeve (11); the end face of the drive side shaft sleeve (1) is provided with grooves (1a), the driven side shaft sleeve (11) is provided with a first steel ball hole, and the steel ball (3) is arranged in the first steel ball hole. According to the servo turret head overload protection device, a mechanical overload protection mechanism is adopted, the fault clearing process is simplified while a knife rest is protected effectively, and the fault clearing and debugging cycle is shortened.

Description

technical field [0001] The invention relates to the field of CNC machine tool servo turret tool holders, in particular to an overload protection device for servo turret tool holders. Background technique [0002] The servo turret tool post, referred to as the servo tool post, is the core functional component of the CNC machine tool. When the machine tool is actually working, due to improper operation and other reasons, it will cause crashes, excessive loads, etc., resulting in damage to the tool holder motor or gear transmission system, or even accidents. Moreover, after an overload fault occurs on the tool holder, it is often necessary to disassemble and assemble the tool holder, which takes a lot of time and manpower. Therefore, it is necessary to design a servo tool holder overload protection device to ensure that the tool holder will not cause too much damage when it encounters an emergency, and it can facilitate troubleshooting, restore the device as soon as possible, ...
