A structure of automatic rotary tool rest of CNC lathe

Abstract

The invention discloses an automatic rotary tool rest structure of a numerically controlled lathe, comprising a base, a motor is installed at one end of the base, and the motor is located in the middle position on the base, a worm is arranged in the base, and the worm is located in the middle of the base Position, the bottom end of the worm is installed with a fixed plate, and the fixed plate is located at the bottom end of the base, the worm is provided with a rotating shaft, and the rotating shaft is located in the middle position on the worm, and the top of the base is installed with a rack In the present invention, a fixed plate is arranged in the base to connect the bottom end position of the rotating shaft, and at the same time, the bottom end position of the rotating shaft is limited, which ensures the fixed position of the rotating shaft when the worm is driven, and effectively solves the problem of protection when the worm rotates. Cylindrical pins are arranged between the shaft sleeve and the disc for fixedly connecting the position of the limit disc, which further solves the problem of the rotation accuracy of the rotating shaft and improves the rotation accuracy of the tool rest seat.

Description

technical field [0001] The invention relates to the technical field of rotary tool rests, in particular to an automatic rotary tool rest structure of a numerical control lathe. Background technique [0002] The rotary tool holder is used in CNC lathes and can be installed on the turret head to hold various tools for different purposes. The automatic tool changing action of the machine tool is realized through the rotation indexing of the turret head. 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] The rotary tool rest in the prior art has many shortcomings; for example, the fixing ability is not good, and there is no protection device for the position limit of the tool rest seat during use, and the rotation accuracy of the rotating shaft is relatively larg...
