[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 This utility model provides a technical solution for a multi-station rotary feeding mechanism for a pneumatic drilling machine: It includes a worktable 1, with four fixing mechanisms 2 mounted above the worktable 1. Each fixing mechanism 2 includes a housing 201, inside which a dual-axis motor 202 is installed. Threaded rods 203 are fixedly mounted on both output ends of the dual-axis motor 202. The end of each threaded rod 203 away from the dual-axis motor 202 is rotatably connected to the inside of the housing 201. A threaded sleeve 204 is threadedly connected to the outer surface of each threaded rod 203. A limit block 205 is mounted on the outer surface of each threaded sleeve 204. Two limit grooves 206 are formed on the upper surface of the housing 201. A fixing block 207 is mounted on the side of each limit block 205 away from the threaded sleeve 204 after passing through the limit groove 206. A connecting block 208 is mounted on the upper surface of each fixing block 207. A damping rod 209 is mounted on the outer surface of each connecting block 208. The outer surface of each damping rod 209 is... A spring 210 is fitted onto each damping rod 209. A rubber block 211 is installed at the telescopic end of each damping rod 209. A sliding rod 212 is installed on the outer surface of each rubber block 211. A stop block 213 is installed at the end of each sliding rod 212 that passes through the connecting block 208, away from the rubber pad. When the fixing block 207 approaches and contacts the workpiece, the rubber block 211 will first contact the workpiece surface. As the fixing block 207 continues to move, the damping rod 209 will contract, compressing the spring 210. The elastic force of 0 ensures that the rubber block 211 always maintains an appropriate clamping force on the workpiece, which not only ensures the stability of the fixation, but also avoids damage to the workpiece due to excessive clamping force. The damping rod 209 can slow down the extension and retraction speed of the spring 210 to prevent the rubber block 211 from impacting the workpiece. At the same time, the sliding rod 212 slides in the connecting block 208 to guide the movement of the rubber block 211. The stop block 213 can prevent the sliding rod 212 from falling out of the connecting block 208 and ensure the integrity of the structure.
[0023] A rotary motor 3 is installed inside the workbench 1. A first gear 4 is installed at the output end of the rotary motor 3. A rotating shaft 5 is rotatably connected inside the workbench 1. The top end of the rotating shaft 5 passes through the workbench 1 and is connected to the turntable body 7. A second gear 6 is installed on the outer surface of the rotating shaft 5. The first gear 4 and the second gear 6 mesh. A set of sliding grooves 8 are opened on the upper surface of the workbench 1 and the bottom surface of the turntable body 7. Multiple balls 9 are slidably connected inside each set of sliding grooves 8. The upper surface of the turntable body 7 is connected to the bottom surface of the four outer shells 201.
[0024] A fixed frame 10 is installed on the upper surface of the workbench 1. A hydraulic rod 11 is installed on the upper surface of the fixed frame 10. The output end of the hydraulic rod 11 passes through the fixed frame 10 and is connected to a mounting plate 12. Two limiting rods 13 are connected to the upper surface of the mounting plate 12. The top end of each limiting rod 13 passes through the fixed frame 10 and extends to the outside of the fixed frame 10. A drilling device 14 is installed on the bottom surface of the mounting plate 12. The hydraulic rod 11 serves as a power component and can move the mounting plate 12 up and down by telescoping, thereby controlling the lifting and lowering of the drilling device 14 to realize the drilling operation on the workpiece. When the mounting plate 12 moves, the two limiting rods 13 will slide synchronously along the through hole of the fixed frame 10, effectively limiting the movement direction of the mounting plate 12 and preventing it from deviating or shaking during the up and down movement. This ensures that the drilling device 14 can accurately position the workpiece to be drilled, improving the drilling accuracy.
[0025] A connecting plate 15 is connected to the outer surface of the fixed frame 10. An electric slide rail 16 is installed on the bottom surface of the connecting plate 15. A sliding seat 17 is slidably connected to the outer surface of the electric slide rail 16. An electric push rod 18 is installed on the bottom surface of the sliding seat 17. A clamping device 19 is installed at the output end of the electric push rod 18. A conveying mechanism 20 is provided below the connecting plate 15. A control panel 21 is installed on the upper surface of the fixed frame 10. The control panel 21 facilitates the operation of the device.
[0026] The working principle of this utility model is as follows: First, the fixing mechanism 2 is adjusted according to the size of the workpiece to be processed. The dual-axis motor 202 is started through the control panel 21, driving the threaded rods 203 on both sides to rotate. Under the guidance of the limiting block 205 and the limiting groove 206, the threaded sleeve 204 drives the two fixing blocks 207 to move synchronously, preparing for the workpiece fixing. Then, the workpiece to be processed is transferred to the fixing mechanism 2 on the turntable body 7 until the rubber block 211 is in contact with both sides of the workpiece. At this time, the damping rod 209 and the spring 210 prevent the workpiece from being damaged through elastic buffering. At the same time, the sliding rod 212 and the stop block 213 ensure the clamping stability and complete the workpiece fixing. Then, the rotary motor 3 is started, and the rotating shaft 5 is driven to rotate through the meshing transmission of the first gear 4 and the second gear 6, so that the turntable body 7 moves with the rotation. The rotating shaft 5 rotates synchronously, and the cooperation between the slide groove 8 and the ball bearing 9 ensures that the turntable rotates smoothly. When the fixing mechanism 2, which holds the workpiece, rotates to directly below the drilling device 14, the turntable stops. Subsequently, the hydraulic rod 11 extends to push the mounting plate 12 down, and the limiting rod 13 guides and limits the mounting plate 12, ensuring that the drilling device 14 accurately contacts the workpiece and completes the drilling operation. After drilling is completed, the hydraulic rod 11 retracts to reset the drilling device 14. The turntable body 7 continues to rotate, sending the drilled workpiece to the unloading area. At this time, as a subsequent step, the electric slide rail 16 drives the sliding seat 17 to move, and the electric push rod 18 drives the clamping device 19 to remove the processed workpiece from the fixing mechanism 2. Then, the conveying mechanism 20 transports it to the next stage, thereby realizing the automatic unloading and circulation of the workpiece.

Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
