The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0021] Please see Figures 1 to 3 A fixing device for processing metal products with an arc-shaped surface is disclosed. The metal product is egg-shaped with the outer diameters at both ends smaller than the outer diameter at the middle section. The device includes a base 1 and a support platform 2 mounted on the base to support the metal product. A rotating clamping assembly 3 is also mounted on the base 1 above the support platform. The rotating clamping assembly includes a pair of adjustable clamps 32, the inner diameters of which are adapted to the outer diameters of the metal product near both ends. The rotating clamping assembly 3 also includes a pair of rotating telescopic mechanisms 31 located on both sides of the clamps. The rotating telescopic mechanism includes a telescopic rod 311 and a connecting rod 312. The connecting rods are a pair, with one end of each connecting rod connected and fixed to the two clamps, and the other end connected and fixed to the telescopic rod, which drives the two clamps to move under the telescopic movement of the telescopic rod.

[0022] The rotary telescopic mechanism 31 also includes a rotatable mounting base 314. The telescopic rod is mounted on the mounting base and rotates with the mounting base. A drive motor 4 is provided on the outside of the mounting base. The drive shaft of the drive motor is connected and fixed to the center of the mounting base so that the mounting base can rotate under the drive of the drive motor.

[0023] A pair of columns 11 are fixedly installed on the base 1. The two columns are located on both sides of the support platform. A rotating seat 12 is fixedly installed on the upper end of the column. A rotating shaft 121 is rotatably installed in the center of the rotating seat. The rotating shaft is fixedly connected to the center of the mounting seat. One end of the rotating shaft in the rotating seat near the drive motor is connected to the mounting seat, and the other end is fixedly connected to the rotating shaft of the drive motor.

[0024] The telescopic rods 311 are multiple and arranged in pairs. Each mounting base 314 has at least two pairs of telescopic rods that cooperate with two clamps respectively. Each telescopic rod is symmetrically arranged on both sides of the axis where the center of the mounting base is located to avoid the rotation axis 121. Each pair of telescopic rods is connected and fixed to each other by a synchronization rod 313 perpendicular to each telescopic rod. The end of the connecting rod 312 away from the clamp is fixedly connected to the center of the synchronization rod.

[0025] The support platform 2 includes a lifting seat 21 and a support plate fixedly installed at the top of the lifting seat. An elastic pad 22 for supporting metal products during processing is fixedly installed on the support plate. The elastic pad is made of soft plastic material, and the inner diameter of the clamp is larger than the outer diameter of the elastic pad.

[0026] A pressure sensor 23 is also installed below the elastic pad 22. Both the pressure sensor and the lifting seat 21 are electrically connected to the telescopic rod.

[0027] In this embodiment, a fixing device for processing metal products with an arc-shaped surface is used. During operation, the telescopic rod 311 extends to open the clamp 32, and the metal product 5 is placed between the two clamps. At the same time, the lifting seat 21 in the support platform 2 moves the support plate up until the elastic pad contacts the bottom of the metal product. The pressure sensor 23 senses the pressure of the metal product and feeds it back to the telescopic rod, causing the upper telescopic rod 311 to retract and move the clamp to press the top of the metal product. The lower telescopic rod extends and moves the clamp down to below the top surface of the elastic pad to reduce interference. The external cutting device performs cutting processing on the metal product. Since the clamps and connecting rods are prone to interfering with the cutting tool during the process, the tool temporarily skips the interference area to complete the processing of other parts. Afterward, the lifting seat descends, the lower telescopic rod retracts to make the two clamps cooperate to clamp the metal product, and under the control of the drive motor, the two clamps rotate to change the orientation of the metal product. The lifting seat rises again to provide support, and the tool executes the second procedure to cut the interference area in the previous step.

[0028] The beneficial effects of this utility model are: the clamp controlled by the rotating telescopic mechanism, combined with the liftable support platform, allows the metal products to rotate and change direction under precise positioning during processing, reducing processing interference, increasing processing flexibility, and making it less likely to damage the metal products due to excessive pressure, thus effectively improving production efficiency and reducing production costs.

Those skilled in the art can make changes, modifications and variations to the above embodiments within the scope of the present invention.
