Compared with the prior art, the invention has the following beneficial effects: the conventional rotary table generally has only a rotating function, that is, the workpiece is placed on the processing platform, and 360 degrees of processing is performed on the workpiece through rotation of the rotary table, but the rotary table can only perform processing of the workpiece in a plane. For some more complex machined parts, machining of the workpiece in the vertical direction is required, which is not possible with current rotary tables. On the basis of the prior art, the invention designs the vertically moving lifting table, and realizes the movement of the workpiece in the vertical direction, so that the rotating table can be matched with a numerical control machine tool to finish the processing of more complex parts. In order to realize the vertical movement of the lifting platform, the invention designs a piston mechanism, and an electromagnetic coil and an electric signal induction device are also designed in the piston mechanism, wherein the electromagnetic coil provides a magnetic field at the bottom of a piston rod, and the electric signal induction device induces an electric signal generated when the piston rod moves, so that the movement speed and the displacement of the piston rod are obtained. According to the general design, only the structure in which the piston rod pushes the elevating table should be designed, but the inventors found that this structure is insufficient in motion smoothness for a precision machine tool. Specifically, if the piston rod directly pushes the lifting platform to move, the lifting platform has small self-mass, so that the acceleration speed is high in the movement process, and the stable movement of the lifting platform is difficult to realize.

The conventional turntable generally includes only a lateral braking structure, and the inventor found that such a structure is not effective in braking and that it is necessary to apply a sufficient pushing force in order to achieve a sufficient braking force due to unidirectional braking, which is very liable to cause deformation of parts of the structure. To overcome this disadvantage, the present invention adds a top brake mechanism to achieve braking of the structure from multiple directions.
