[0002] In laboratory environments, drilling machines are commonly used processing equipment, widely applied in drilling, reaming, and other preparation processes for various samples. The stability of workpiece clamping directly affects processing accuracy and operational safety. Workpieces are typically fixed using clamping devices. However, existing auxiliary clamping devices for drilling machines are prone to damaging samples during clamping, causing slippage and breakage due to unstable clamping. Furthermore, the clamping force adjustment of existing clamping devices relies on manual operation and lacks a real-time feedback mechanism. Excessive clamping force can cause workpiece deformation, while insufficient clamping force can lead to workpiece loosening during processing, potentially causing safety accidents. Therefore, there is an urgent need for an auxiliary clamping device for drilling machines to solve these problems. Utility Model Content

[0003] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide an auxiliary clamping device for a drilling machine.

[0012] Example 1, such as Figure 1 , Figure 2 and Figure 3 As shown, an auxiliary clamping device for a drilling machine includes a base 1 with a rotating seat 2 rotatably mounted on top. Adjusting handles 3 are threaded onto both sides of the rotating seat 2. A jaw fixing seat 4 is mounted on top of the rotating seat 2. A fixed jaw 5 is mounted on one side of the top of the jaw fixing seat 4. A movable seat 6 is slidably mounted inside the jaw fixing seat 4. A movable jaw 7 is mounted on one side of the top of the movable seat 6. A nut 8 is mounted on the outer side of the movable seat 6. A rotating rod 9 is mounted inside the nut 8. A handle 10 is mounted on the outer side of the rotating rod 9. A screw 11 is connected to the inner side of the rotating rod 9. The screw 11 is rotatably mounted inside the nut 8 and connected to a nut seat 12. The nut seat 12 is mounted on the rotating seat 2. The fixed jaw 5 and the movable jaw 7 are connected at the top... Each jaw is provided with a stepped groove 13, and the bottom of the stepped groove 13 is provided with several evenly arranged assembly grooves 14. A clamping component 15 is installed in the assembly groove 14. A fixing seat 16 is installed in the stepped groove 13. The fixing seat 16 is locked in the stepped groove 13 by bolts and pressed onto the clamping component 15. A cutting blade 17 is provided on one side of the fixing seat 16 and is located in the stepped groove 13. A straight surface 18 is provided on the other side of the fixing seat 16 and fits against the clamping component 15. A pressure sensor 19 is installed in the fixed jaw 5 and is located between the fixed jaw 5 and the clamping component 15. The pressure sensor 19 is connected to a pressure display 20 and is installed on the jaw fixing seat 4.

[0013] In this embodiment, during use, the angle of the rotating seat 2 can be adjusted according to the processing requirements of the workpiece. After adjusting to the required angle, tighten the adjusting handles 3 on both sides to fix the rotating seat 2. Then, place the workpiece between the fixed jaw 5 and the movable jaw 7, rotate the handle 10, and through the helical transmission of the rotating rod 9 and the screw 11, drive the movable seat 6 to move along the guide of the jaw fixed seat 4 towards the fixed jaw 5 until the clamping assembly 15 clamps the workpiece. During the clamping process, the pressure sensor 19 receives clamping pressure and sends the information to the pressure display 20. By observing the value of the pressure display 20, when the pressure value reaches the clamping pressure required for workpiece processing, stop rotating the handle 10 to complete the clamping of the workpiece, preventing excessive clamping force from causing workpiece deformation, or insufficient clamping force from causing the workpiece to loosen during processing.

[0014] When it is necessary to cut the workpiece, the fixed seat 16 can be removed from the stepped groove 13 first, then the clamping assembly 15 can be removed, and then the installation position of the fixed seat 16 can be changed so that the cutting blade 17 on the fixed seat 16 faces inward and the cutting blades 17 on both sides correspond. Finally, the fixed seat 16 is locked and installed in the stepped groove 13 by bolts, and the handle 10 is turned again so that the movable jaw 7 drives the cutting blade 17 to move towards the cutting blade 17 on the fixed jaw 5, thereby achieving the cutting effect.

[0016] In this embodiment, during use, by rotating the handle 10, the movable seat 6 is moved by the helical transmission of the rotating rod 9 and the screw 11. The movable seat 6 drives the movable jaw 7, which in turn drives the assembly block 23 through the assembly groove 14.

[0018] In this embodiment, during use, by rotating the handle 10, the movable seat 6 is moved by the helical transmission of the rotating rod 9 and the screw 11. The movable seat 6 drives the movable jaw 7, which in turn drives the assembly block 23 through the assembly groove 14. The assembly block 23 drives the clamping plate 24, which in turn drives the arc-shaped clamping groove 25 to move towards the clamping plate 24 on the fixed jaw 5 until the arc-shaped clamping grooves 25 on both sides clamp the cylindrical workpiece. The anti-slip pad 26 can prevent slippage, and at the same time, the pressure sensor 19 detects the pressure generated by clamping to prevent damage to the workpiece.

[0019] Example 4, as Figure 5 As shown, this embodiment adds the following structure based on embodiment 1: the clamping assembly 15 also includes an assembly plate 27, a V-shaped clamp 28 is mounted on the assembly plate 27, and an assembly block 23 is mounted on the back of the assembly plate 27.

[0020] In this embodiment, during use, by rotating the handle 10, the movable seat 6 is moved by the helical transmission of the rotating rod 9 and the screw 11. The movable seat 6 drives the movable jaw 7, which in turn drives the assembly block 23 through the assembly groove 14. The assembly block 23 drives the assembly plate 27, which in turn drives the V-shaped clamp 28 to move towards the V-shaped clamp 28 on the fixed jaw 5 until the V-shaped clamps 28 on both sides clamp the workpiece. The V-shaped clamp 28 can accommodate cylindrical, square, and other workpieces of different diameters. At the same time, the pressure sensor 19 detects the pressure generated by clamping to prevent damage to the workpiece.

[0021] Example 5, as Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: a transparent cover 29 is installed on the outside of the pressure display 20 for the jaw fixing base 4.
