[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-4The utility model provides a technical solution: a fixing fixture for drilling holes on the surface of metal products, comprising a placing table 1, on which are slidingly provided annular connecting blocks 2, on which are rotatably installed a cylindrical block 3, and the lower end of the placing table 1 is provided with a driving component for driving multiple connecting blocks 2 to simultaneously move inward or spread outward, and a driving motor 12 is installed on the symmetrically arranged connecting blocks 2, and the output end of the driving motor 12 is connected to the central axis 7 of the cylindrical block 3.

[0018] The driving motor 12 is a servo motor or a stepping motor, which has a self-locking function.

[0019] Specifically, the placing table 1 is disc-shaped, and is provided with a circular strip opening 4 extending outward from the center of the placing table 1. The connecting block 2 is located in the strip opening 4. A limiting block 5 is provided on the outer wall of the connecting block 2, and the limiting block 5 is slidably provided in the limiting groove 6 opened in the strip opening 4.

[0020] Specifically, the driving assembly includes a connecting plate 8 and a gear shaft 9 respectively fixedly connected to the bottom of the connecting block 2. The outer wall of the connecting plate 8 is provided with a accommodating cavity 10. The gear shaft 9 is located in the accommodating cavity 10. One side wall of the accommodating cavity 10 is engaged with the gear shaft 9. The gear shaft 9 is equipped with a motor 11 for driving it to rotate.

[0021] Specifically, the plurality of connecting plates 8 are arranged longitudinally, and the connecting blocks 2 extend downward to be connected to the connecting plates 8 .

[0022] Specifically, the drive motor 12 is installed in the installation opening 13 opened on the connecting block 2. A connecting port 14 is opened between the installation opening 13 and the top surface of the connecting block 2. The output end of the drive motor 12 passes through the connecting port 14 and is connected to the central axis 7 of the cylindrical block 3.

[0023] Working principle: When the present invention is used, first place the cylindrical metal product on the placing table 1 according to the size of the cylindrical metal product, and according to the processing requirements, the cylindrical block 3 is located on the inner or outer side of the annular workpiece, and then start the motor 11, the motor 11 drives the gear shaft 9 to rotate, and the accommodating cavities 10 on the multiple connecting plates 8 engage with the gear shaft 9, so that the connecting plates 8 push the connecting blocks 2 to move in the strip opening 4, and the limit blocks 5 slide in the limit grooves 6 until the cylindrical blocks 3 are tightly fitted with the cylindrical metal product. The self-locking of the driving motor 12 makes the symmetrical cylindrical blocks 3 unable to rotate, thereby clamping and fixing the cylindrical metal product. When the punching position needs to be adjusted, start the driving motor 12, and the driving motor 12 drives the cylindrical block 3 to rotate. Under the action of the friction between the cylindrical block 3 and the surface of the cylindrical metal product, the cylindrical metal product is driven to rotate, and the position where the hole needs to be punched is adjusted to the corresponding punching equipment, thereby increasing work efficiency.
