[0003] Chinese Patent with the authorization announcement number CN220330044U discloses a drilling device for machining an abacus wheel, which includes a base. An electric lifting rod is fixedly installed at the rear side of the upper surface of the base. The top of the electric lifting rod is fixedly installed with a fixed disk. The side surface of the fixed disk is evenly distributed along the circumferential direction and installed with a reciprocating assembly. A clamping block is installed at the inner side end of the reciprocating assembly in front of the fixed disk. A telescopic assembly is installed at the front side of the upper surface of the base. The rear end of the telescopic assembly is installed with a drilling assembly corresponding to the fixed disk. For this abacus wheel machining drilling device, through the reciprocating movement of three reciprocating assemblies driving three clamping blocks, it is convenient to quickly and conveniently automatically clamp and position abacus wheels of different sizes.

In summary, the machining efficiency and quality of the abacus wheel are greatly improved, which provides convenience for the drilling machining of the abacus wheel.

[0004] The above patent only fixes the shaft-like part through the clamping block. Although it can play a role in stabilizing the workpiece, it is inconvenient to install. When the length of the workpiece is long, there is no support under the workpiece, and it is easy to produce an eccentric problem during the machining process. The fixing method for the workpiece is poor. Content of the Utility Model

At the same time, providing pressure above and providing blockage on the side improves the stability effect of the workpiece. The rotation of the screw rod is used to drive the blocking plate to displace, support and resist on one side of the workpiece, and stabilize the machining of the workpiece. The displacement of the blocking plate is beneficial to the machining operation of workpieces of different lengths.

[0006] To achieve the above object, the present utility model provides the following technical solution: A drilling device for processing outer star wheels, including a bottom plate, on the surface of which a clamping table is fixed, and a workpiece is placed on the clamping table.

On one side of the workpiece, stabilizing rods are symmetrically provided, and the stabilizing rods pass through the blocking plate. The position of the blocking plate is used to limit the displacement of the workpiece and prevent the force generated during processing from causing the workpiece to shift backward. Below the blocking plate, there are T-shaped sliders corresponding to the T-shaped sliding grooves, which facilitates the installation of the blocking plate and the sliding adjustment of the position of the blocking plate relative to the clamping table;

[0007] The blocking plate is detachably connected with an L-shaped plate, and a first cylinder is fixed on the L-shaped plate. The output end of the first cylinder is connected with a second cylinder. The second cylinder is used to squeeze the workpiece, and the first cylinder is used to adjust the position of the second cylinder and change the squeezing position of the second cylinder.

[0008] Furthermore, an air rod is provided in the second cylinder, and a fitting plate is fixed below the air rod. The fitting plate moves downward and presses on the upper part of the workpiece, providing pressure above the workpiece to stabilize the workpiece.

[0009] Furthermore, side columns are fixed on both sides of the second cylinder, and positioning rods are provided on both sides of the second cylinder and fixed on the surface of the L-shaped plate.

The displacement advancement of the baffle plate can adjust the horizontal position of the workpiece and is applicable when the length of the drill bit is insufficient to reach into the workpiece for machining. Under the displacement of the baffle plate, the workpiece is pushed to move, thus compensating for the problem of insufficient drill bit length. The fitting plate moves downward and presses above the workpiece, providing pressure above the workpiece to stabilize the workpiece. At the same time, providing pressure above and providing obstruction on the side improve the stability effect of the workpiece.

[0015] The positioning rod is used to stabilize the displacement of the second cylinder, preventing deviation when driven by the first cylinder. The rotation of the screw rod is used to drive the baffle plate to displace, support and resist on one side of the workpiece to stabilize the machining of the workpiece.

When the blocking plate 12 needs to be moved, it is only necessary to start the motor 31, and the screw 32 rotates to drive the blocking plate 12 to move, supporting and resisting against one side of the workpiece 2 to stabilize the processing of the workpiece 2. The semicircular arc structure above the clamping platform 11 can be used to adapt to the workpiece 2 well, and for the placement of the workpiece 2, the workpiece 2 can be directly placed on the top of the clamping platform 11 for easy installation. The horizontal position of the workpiece 2 can be adjusted by the displacement of the blocking plate 12. It is suitable for when the length of the drill bit is not enough to extend into the workpiece 2 for processing, and the workpiece 2 is pushed to move under the displacement of the blocking plate 12, so as to make up for the problem of insufficient drill bit length.

[0023] A stabilizing rod 3 is symmetrically provided on one side of the workpiece 2 , wherein the stabilizing rod 3 passes through the blocking plate 12 ; under the action of the stabilizing rod 3 , the blocking plate 12 can be facilitated to slide on the stabilizing rod 3 , further improving the sliding of the blocking plate 12 .
