[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] Example:

[0023] refer to Figures 1 to 6 , an adjustable supporting fixture includes a base 1 and several floating supporting seats 3 movably connected to the base 1 along the vertical direction based on a lifting and adjusting component 2. On the floating supporting seat 3, there are several floating supporting rods 5 for abutting and supporting the bottom surface of the special-shaped workpiece evenly and movably connected based on the floating component 4. When the workpiece abuts the floating supporting rod 5, the position of the floating supporting rod 5 will be automatically adjusted according to the shape of the workpiece, thereby adaptively supporting workpieces of different shapes. The floating supporting seat 3 is also slidably connected with a crimping block 7 for crimping the top surface of the special-shaped workpiece based on the sliding rod 6. The bottom of the crimping block 7 is an arc-shaped structure. The top surface of the workpiece is crimped by the crimping block 7 and the bottom surface of the workpiece is abutted by the floating support rod 5, thereby realizing the support and positioning of the workpiece.

[0024] refer to Figure 2 and Figure 3 Specifically, the lifting and adjusting assembly 2 includes a lifting screw 21 rotatably connected to the base 1 and a lifting screw block 22 rotatably connected to the lifting screw 21. The floating support seat 3 is fixedly connected to the lifting screw block 22. A spiral groove cooperating with the lifting screw 21 is provided on the lifting screw block 22. The lifting screw 21 is rotated to drive the lifting screw block 22 and the floating support seat 3 to move up and down, thereby adjusting the height of the floating support seat 3, thereby adjusting the support state of the workpiece, so that the workpiece can meet the processing requirements.

[0025] refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6Specifically, the floating support seat 3 is divided into a lower oil storage block 31 fixedly connected to the lifting screw block 22 and an upper oil storage block 32 fixedly connected to the lower oil storage block 31 based on a locking screw 33. A sealing ring 34 is fixedly connected between the lower oil storage block 31 and the upper oil storage block 32 to meet the sealing requirements. The floating assembly 4 includes a plurality of floating grooves 41 evenly opened on the upper oil storage block 32 for the floating support rod 5 to move. A floating block 42 is fixedly connected to the bottom of the floating support rod 5. An oil storage groove 43 is opened at one end of the upper oil storage block 32 near the lower oil storage block 31. Several floating grooves 41 are connected to the oil storage grooves 43. The oil reservoir 43 is filled with hydraulic oil. The floating block 42 presses the hydraulic oil, thereby driving the floating support rod 5 to achieve floating contact. By injecting hydraulic oil into the oil reservoir 43, when the floating support rod 5 abuts the bottom of the workpiece, gravity causes the workpiece to press the floating support rod 5 downward, driving the floating block 42 to press the hydraulic oil, causing the hydraulic oil level to drop. Meanwhile, the hydraulic oil level in the other floating tanks 41 rises. The hydraulic oil then exerts buoyancy and support on the floating block 42, enabling the floating support rod 5 to abut against the bottom of the workpiece. The position of the floating support rod 5 automatically adjusts according to the shape of the workpiece. In this embodiment, the floating block 42 is made of silicone. The floating support rods 5 are arranged in a circular pattern on the upper oil reservoir 32. At least two circles of floating support rods 5 are provided on the upper oil reservoir 32 to ensure that the workpiece can contact more floating support rods 5, thereby improving support stability.

[0026] Brief description of the usage process: The floating support rod 5 is placed against the bottom of the workpiece. Due to the action of gravity, the workpiece presses the floating support rod 5 downward, thereby driving the floating block 42 to press the hydraulic oil so that the liquid level of the hydraulic oil drops, while the liquid level of the hydraulic oil in other floating grooves 41 rises. At this time, the buoyancy and supporting force of the hydraulic oil on the floating block 42 are used to achieve the abutment support of the floating support rod 5 on the bottom surface of the workpiece. The position of the floating support rod 5 will be automatically adjusted according to the shape of the workpiece. At the same time, the height of the floating support seat 3 is adjusted by the lifting and adjusting component 2, thereby adjusting the supporting state of the workpiece.

After reading this specification, those skilled in the art may make creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
