[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not intended to limit the present invention.

[0022] Reference Figure 1-3 The present invention provides a dual-tool gantry with replaceable tool heads, which is mounted above the lathe clamping base. The gantry comprises a U-shaped bracket 1, a drive unit 2, a lifting unit 3, a first working seat 4, a second working seat 5, a left drive assembly 6, a right drive assembly 7, and a rotary replacement member 8.

[0023] Two drive units 2 are located on the left and right sides of the U-shaped bracket 1, respectively. Drive units 2 are preferably screw-driven mechanisms, and both drive units 2 are connected to the same drive motor. The lifting unit 3 is preferably a long strip with a protrusion in its center facing the U-shaped bracket 1 to increase the lifting unit's bearing capacity, enhance its stability, and strengthen its rigidity. Its two sides are slidably connected to the U-shaped bracket 1. The drive units 2 are connected to the lifting unit 3 and drive the lifting unit 3 up and down on the U-shaped bracket 1. The first and second workstations 4 and 5 are both slidably connected to the lifting unit 3. A left drive assembly 6 and a right drive assembly 7 are located on the left and right sides of the lifting unit, respectively, and drive the first and second workstations 4 and 5, respectively. Both the left and right drive assemblies 6 and 7 are screw-driven mechanisms. The left drive assembly 6 is positioned at a higher level than the right drive assembly 7, and the drive path of the left drive assembly 6 partially or completely overlaps with the drive path of the right drive assembly 7. A rotating replacement element 8 is provided at the bottom end of the second workstation 5. The rotating replacement element 8 is rotationally connected to the second workpiece and connected to the central control for rotational control. The rotating replacement element 8 is surrounded by a plurality of tool holders 81. Tool holders 81 come in at least two types, including but not limited to radial tool holders 81 and axial tool holders 81. These holders are used to securely hold tools, and tools can be switched by rotating the rotating replacement element 8. Multiple weight-reducing holes 11 are provided on the rear side of the lifting unit 3 and the sidewalls of the U-shaped bracket 1.

[0024] Working principle: Input the lathe control instructions into the central control. At this time, the lifting unit 3 and the working unit move to the target position and start working. When it is necessary to switch the processing mode, the second working seat 5 is moved up, and then the rotating replacement part 8 is rotated to replace the tool.
