Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As with the fourth axis of the market described in the background, the tooling and commissioning time is long and expensive.

Therefore, the utility model provides a fourth shaft rotating platform aiming at the problems in the prior art, which comprises a supporting seat 1 and a workbench 7, wherein the supporting seat 1 comprises a first supporting seat 101 and a second supporting seat 102 which are symmetrical, a positioning pin 2 and a first locking screw 5 are arranged on the first supporting seat 101, a second locking screw 501 is arranged on the second supporting seat 102, a first rotating disk 301 is rotatably arranged on the inner side of the first supporting seat 101, a second rotating disk 3 is rotatably arranged on the inner side of the second supporting seat 102, the first rotating disk 301 and the second rotating disk 3 are coaxial, two ends of the workbench 7 are respectively connected with the first rotating disk 301 and the second rotating disk 3, a positioning hole is arranged on the first rotating disk 301, and the workbench 7 is driven by the first rotating disk 301 and the second rotating disk 3 to rotate around the central axis.

In some more specific embodiments, the first locking screw 5 is provided with 2 symmetrical pieces, and the second locking screw 501 is provided with 2 symmetrical pieces.

The table 7 is provided with flat tongs or indexing tools for holding a workpiece and a three-jaw chuck (not shown).
