The device adjusts the caliber of the drill slag splashing protection ring according to the shape of the workpiece, reduces the horizontal moving distance of the upwardly splashing drill slag, thereby reducing the required intercepting height, and further improves the residue splashing protection effect of the device on the workpiece.

[0026] The working principle of the protective radial drilling machine provided by this utility model is as follows: When drilling a workpiece using the radial drilling machine, the workpiece slag splash protection ring formed by the U-shaped baffle 41, L-shaped baffle 42, and transverse baffle 43 intercepts and protects against the slag splash during the drilling process. The workpiece is placed on the placement seat 3, and then, according to the size of the workpiece, the operator rotates knob 45 to drive the bidirectional lead screw 44 to rotate. The bidirectional lead screw 44 is threaded, causing the two U-shaped baffles 41 to move away from or towards the center of the device along the slide groove, thereby protecting the workpiece from slag splash. The longitudinal diameter of the workpiece slag spatter protection ring formed between plate 42 and transverse baffle 43 is adjusted. During this process, transverse baffle 43 slides adaptively along adjacent slide groove 47 via corresponding slide block 48. Then, knob 464 is rotated to drive gear 463 to rotate via shaft 461. Gear 463 is engaged with rack plate 462, causing two adjacent L-shaped baffles 42 to move closer or further apart along U-shaped baffle 41, thereby adjusting the transverse diameter of the workpiece slag spatter protection ring formed between U-shaped baffle 41, L-shaped baffle 42, and transverse baffle 43. Rotating the locking stud 49 causes its rear end to move backward through the threaded connection with the U-shaped baffle 41, thereby pressing and fixing the adjacent L-shaped baffle 42. This limits the diameter variation of the adjusted workpiece slag splash protection ring. The diameter of the workpiece slag splash protection ring is adjusted according to the shape of the workpiece, bringing it closer to the workpiece's perimeter. This prevents the slag from splashing upwards during subsequent drilling due to an excessively large diameter, which would otherwise result in a greater horizontal interception distance and a higher upward height after the slag has moved laterally a certain distance. The height of the protective device itself will cause the drill cuttings splash protection ring to overflow. The device adjusts the diameter of the drill cuttings splash protection ring according to the shape of the workpiece. By reducing the horizontal movement distance of the upward-splashing drill cuttings, the required interception height is reduced, thereby improving the device's protection effect against workpiece residue splash. Subsequently, the microcontroller 2 starts the motor 9, causing its output shaft to drive the drill bit 8 to rotate. The microcontroller 2 starts the motor 11, causing its output shaft to drive the stud 10 to rotate. The stud 10 is connected by threads, causing the vertical moving frame 6 to slide vertically along the damping rotating shaft 5, thereby adjusting the drilling height of the radial drilling machine.

[0027] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM32, and both motor 9 and motor 11 can be YEJ6324. The microcontroller 2 controls the operation of motor 9 and motor 11 using methods commonly used in the prior art.
