Description

Technical Field

[0001] This utility model relates to the field of machine tool manufacturing technology, and more specifically, it relates to a turret machine for CNC machine tools. Background Technology

[0002] A turret machine mounted on a CNC machine tool can be used for machining with various cutting tools. As the number of tools mounted on the cutter head increases, the cutter head diameter needs to be increased; otherwise, sufficient space cannot be provided for loading and unloading. However, with the continuous increase in cutter head diameter, the size of the turret machine also increases accordingly, making it difficult to load onto CNC machine tools, resulting in cumbersome operation, inflexible movement, and poor overall performance. Therefore, this utility model proposes a turret machine for CNC machine tools. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a turret machine for CNC machine tools, which has the characteristics of compact structure, small size and flexible turnover.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The CNC machine tool turret machine involved in this utility model includes a machine base, a turret platform slidably connected to the machine base, a linear reciprocating motion mechanism for controlling movement on the turret platform, the linear reciprocating motion mechanism being disposed on the machine base, a solid inner shaft and a hollow outer shaft being rotatably connected to the turret platform, the outer shaft being coaxial with the inner shaft, and the outer shaft being sleeved on the inner shaft;

[0005] One end of the inner shaft is provided with a first cutter head, and the other end is provided with a first driven gear. A first driving gear meshes with the first driven gear, and a first motor that controls the rotation is connected to the first driving gear. The first motor is located on the tower platform.

[0006] One end of the outer shaft is provided with a second cutter head, and the other end is provided with a second driven gear. A second driving gear meshes with the second driven gear, and a second motor that controls the rotation is connected to the second driving gear. The second motor is located on the tower platform.

[0007] The present invention is further configured such that: a bearing is provided between the outer shaft and the inner shaft, with the inner ring sleeved outside the inner shaft and the outer ring embedded inside the outer shaft.

[0008] The present invention is further configured such that the first cutter head and the second cutter head are located at the same end of the inner shaft and the outer shaft.

[0009] The present invention is further configured such that the first cutter head and the second cutter head are located at different ends of the inner shaft and the outer shaft.

[0010] The present invention is further configured such that both the first motor and the second motor are servo motors.

[0011] In summary, the present invention has the following beneficial effects: The CNC machine tool turret machine involved in the present invention replaces one tool head with a large tool head by using two tool heads with a small tool load. This greatly reduces the diameter of the two tool heads with a small tool load, thereby reducing the overall size of the turret machine. This makes it easy to install on CNC machine tools and allows for flexible turnover. The overall function is complete and the practicality is strong. Attached Figure Description
