A self-adaptive detection clamping force chuck for lathe

Abstract

A lathe chuck with self-adaptive detection of clamping force, comprising a feedback device, a high jaw, a chuck body, and a control device, the feedback device is installed on the high jaw, and the feedback device includes a first installation area, a force-bearing area and the second installation area; the chuck control device includes a servo motor, a gear pump, an oil tank, a filter, and an oil cylinder. The present invention adopts the sensor and the high claw to be fixed as a whole, does not change the shape of the high claw, and adopts the wireless transmission method, which will not affect the normal use of the chuck, and can detect the clamping force of the chuck in the working state in real time, detect The data is sent by the wireless transmitting device, and after being received by the wireless receiving device, the data is transmitted to the controller. The controller adjusts the gear pump speed by controlling the servo motor, changes the system flow and pressure, and then achieves the function of adjusting the clamping force and ensuring the processing process. The middle workpiece will not be separated from the chuck due to too small clamping force, and the workpiece will not be deformed due to too large clamping force, ensuring normal production.

Description

[0001] The invention relates to the technical field of machine tool clamping, in particular to an adaptive detection clamping force chuck for a lathe. Background technique [0002] When the chuck clamps the workpiece for high-speed rotation, due to the action of centrifugal force on the jaws, part of the clamping force will offset the centrifugal force, reducing the clamping force. When the clamping force of the chuck is not enough to clamp the workpiece The workpiece will fly out and cause safety accidents. The loss of clamping force is the main reason that restricts the increase of chuck speed and poses a safety threat. Real-time detection of chuck clamping force and adjustment of chuck clamping force according to the detection results The size can ensure that the workpiece will not break away from the chuck due to too small clamping force during processing, and will not deform the workpiece due to excessive clamping force, so as to achieve the purpose of safe production.
