Ball screw elliptic reverser nut turning and milling clamp

Abstract

The invention provides a ball screw elliptic reverser nut turning and milling clamp, which comprises a tensioning sleeve, a hollow tensioning core shaft and a locking shaft, wherein the tensioning sleeve comprises an end part with an inner threaded hole and a sleeve body communicated with the inner threaded hole, and the sleeve body is provided with axial grooves uniformly distributed along the circumference; the front end of the tensioning core shaft extends into the tensioning sleeve, and the contact surface of the tensioning sleeve and the tensioning core shaft is a conical surface; and the front end of the locking shaft penetrates through the tensioning core shaft and is in threaded connection with the end part of the tensioning sleeve, and the rear end of the locking shaft is exposed from the tensioning core shaft and axially and fixedly connected with the tensioning core shaft. The clamp has the advantages of realizing machining of a ball screw nut reverser hole based on an internal thread and improving the machining efficiency and the machining precision.

Description

technical field [0001] The invention relates to a clamp, in particular to a turning and milling clamp for an elliptical reverser nut of a ball screw pair. Background technique [0002] The internal thread of the ball screw sub-nut and the processing of the reverser hole are relatively cumbersome, and the processing tool for the reverser hole cannot be used to locate the position of the reverser hole based on the internal thread, so when processing the ball nut, it is necessary to accurately locate it first After the position of the reverser hole is finished, the internal thread is processed based on the reverser hole. It is difficult to control the position deviation between the internal thread and the reverser hole when turning the internal thread of the nut, and the strong intermittent cutting seriously damages the tool. And the completeness of the reverser hole, the whole machining process needs multiple tool setting, the machining efficiency is low, the accuracy of the w...
