Automatic rotary tool rest structure for numerically controlled lathe

Abstract

The invention discloses an automatic rotary tool rest structure for a numerically controlled lathe. The automatic rotary tool rest structure comprises a base, wherein a motor is installed at one end of the base, the motor is located in the middle of the base, a worm is installed in the base, the worm is located in the middle of the interior of the base, a fixing plate is installed at the bottom end of the worm, the fixing plate is located at the bottom end of the interior of the base, a rotating shaft is installed on the worm, the rotating shaft is located at the middle of the worm, and a rackis installed at the top end of the base. According to the automatic rotary tool rest structure for the numerically controlled lathe, the fixing plate is installed in the base to be connected with thebottom end position of the rotating shaft and limit the bottom end position of the rotating shaft at the same time, it is guaranteed that the position of the rotating shaft is fixed during worm transmission, and the protective problem when the worm rotates is effectively solved; and cylindrical pins are installed between a shaft sleeve and a disc to be fixedly connected with the position of a limiting disc, the rotating precision of the rotating shaft is further achieved, and the rotating precision of the tool rest base is improved.

Description

technical field [0001] The invention relates to the technical field of rotary tool holders, in particular to an automatic rotary tool holder structure for a numerically controlled lathe. Background technique [0002] The rotary tool post is used for CNC lathes. It can be installed on the turret head to hold various tools for different purposes. The automatic tool change action of the machine tool can be realized through the rotary indexing of the turret head. Its form generally has a vertical shaft type. And the horizontal axis type, the vertical axis type is generally a square or hexagonal tool holder, which can install four or six tools respectively; the horizontal axis type is usually a disc type rotary tool holder, which can install a large number of tools. [0003] There are many deficiencies in the rotary tool holder in the prior art; for example, the fixing ability is not good, and there is no protection device for the position limit of the tool holder seat during use...
