AI Technical Summary

Technical Problem

In some use cases, the shaft shaking causes both sides to be unable to be fixed, affecting the stability of the clamping.

Method used

A shaft clamping device is designed, including an intermediate sleeve and end sleeves on both sides. The end sleeves on both sides are connected by a symmetrically arranged threaded cylinder, and the opening and closing of the end sleeve is controlled through a butterfly screw plug and a long rod to achieve stable clamping of the shaft parts.

Benefits of technology

Through the design of threaded barrels and butterfly screw plugs arranged symmetrically on both sides, the proximity or distance of the end sleeves on both sides can be controlled simultaneously, improving the stability of tightening, simple operation, and improving machining efficiency.

Abstract

The utility model discloses a shaft holding device. The shaft holding device comprises a middle sleeve and end sleeves located on the two sides of the middle sleeve. Threaded barrels are symmetrically arranged on the two sides of the middle sleeve, and the threaded barrels are sleeved with the end sleeves. Three groups of butterfly-shaped screw plugs and three groups of long rods are arranged on the side wall of the middle sleeve; wherein an open conical sleeve connected with the threaded sleeve is arranged in the end sleeve, and the conical sleeve is opened and closed through back-and-forth displacement of the end sleeve. The end sleeves on the two sides are connected through the threaded cylinders symmetrically arranged on the two sides, and due to the fact that the threads of the threaded cylinders on the two sides are opposite, when the middle sleeve is rotated, the end sleeves on the two sides can be controlled to be close to or away from each other at the same time, and therefore the conical holes in the end sleeves control opening and closing of the open conical sleeve; therefore, the shaft part can be held or loosened on the two sides at the same time, the holding stability is effectively improved, operation is easy, and the machining efficiency is improved.
