When processing the torque control arm, the drilling device accurately controls the moving trajectory and speed of the drill bit through the control system so that it can drill according to the predetermined position and depth. At the same time, the cooling system and lubrication system inside the device will work together to reduce the temperature and friction of the drill bit and improve the drilling efficiency and quality. The drilling device for processing torque control arms is widely used in the fields of automobile manufacturing, machinery manufacturing, aerospace, etc., and is used to process holes on torque control arms of various specifications and materials.

[0015] A drilling method of a drilling device for processing a torque control arm, comprising the following steps:

[0016] Step 1: Start the vacuum pump and open the valve of the suction pipe. As the vacuum pump sucks air, the air in the paraffin fixing mechanism is discharged. After the air is discharged, the valve of the suction pipe is closed. The paraffin heating mechanism is opened to heat the paraffin in the paraffin heating chamber. The added paraffin is liquefied. The liquefied paraffin is extracted by the liquid pump and injected into the paraffin fixing mechanism through the paraffin filling pipe. When the paraffin capacity in the paraffin fixing mechanism is half full, the valve of the paraffin filling pipe is closed.

[0017] Step 2: Clamp the torque control arm, adjust the front and rear position of the drilling drive frame through the first screw, adjust the left and right position of the mounting seat through the second screw, adjust the height of the vacuum suction cup clamping mechanism through the vacuum suction cup clamping mechanism screw, and use the motor in the sliding block of the vacuum suction cup clamping mechanism to drive the vacuum suction cup clamping mechanism rotating block to rotate and extend the vacuum suction cup clamping mechanism electric telescopic cylinder to let the vacuum suction cup clamping mechanism clamp the torque control arm and then place it on top of the paraffin fixing mechanism, so that the paraffin fixing mechanism and the lower surface of the torque control arm are completely fitted, and wait for the paraffin to cool and set. The cooled paraffin and the torque control arm The lower surface fits perfectly, so that the force on the lower side of the torque control arm is evenly distributed. With the flexible pressing of the vacuum suction cup clamping mechanism, the stability of the drilling process is ensured, and the shaking and jitter caused by uneven force are reduced. The contact force between the drill bit and the workpiece is balanced, which helps to reduce the deviation caused by uneven force. The even force can significantly reduce the error in the drilling process. The even force clamping method can reduce the friction and wear between the drill bit and the workpiece, thereby reducing the risk of damage to the drill bit and the workpiece. The even force clamping method can reduce unexpected situations caused by uneven force, such as drill bit breakage or workpiece flying out.

[0018] Step 3: After the paraffin is shaped, the height of the drilling turntable mechanism is adjusted by the lead screw of the drilling turntable mechanism, and then the corresponding drill bit is selected according to the thickness of the torque control arm and the required process, and the drill bit fixing disk driving motor is started. The output end of the drill bit fixing disk driving motor drives the drill bit fixing disk driving gear to rotate, and the drill bit fixing disk driving gear drives the drill bit fixing disk provided with an internal gear to rotate outside the drilling motor fixing plate through meshing until the required drill bit is located below the drilling motor, and the lead screw of the movable coupling block is adjusted to drive the movable coupling block provided with the sliding end of the movable coupling block to move toward the fixed coupling block, so that the coupling block limit block and the coupling block limit block groove are adapted, and then the first electromagnet block is connected, and the first magnet block and the first electromagnet block are magnetically attracted to each other, completing the transmission connection between the drilling motor and the drill bit, and starting the drilling motor drives the drill bit to rotate, thereby drilling the torque control arm;

[0019] Step 4: When the style of the torque control arm changes, the sliding drive motor is started to rotate forward, and the sliding drive motor drives the supporting skateboard drive gear to rotate. The supporting skateboard drive gear drives the supporting skateboard provided with the supporting skateboard tooth row to slide to the side away from the paraffin fixing mechanism through meshing.

When the paraffin capacity in the paraffin fixing mechanism is half filled, the valve of the paraffin filling pipe is closed, and the vacuum suction cup clamping mechanism clamps the torque control arm and then places it above the paraffin fixing mechanism, so that the paraffin fixing mechanism is completely fitted with the lower surface of the torque control arm, and the paraffin is cooled and fixed. The cooled paraffin is completely fitted with the lower surface of the torque control arm, so that the torque The force on the lower part of the control arm is evenly distributed, and the flexible pressing of the vacuum suction cup clamping mechanism ensures the stability of the drilling process and reduces the shaking and jitter caused by uneven force. The contact force between the drill bit and the workpiece is balanced, which helps to reduce the deviation caused by uneven force. The even force can significantly reduce the error in the drilling process. The even force clamping method can reduce the friction and wear between the drill bit and the workpiece, thereby reducing the risk of damage to the drill bit and the workpiece. The even force clamping method can reduce unexpected situations caused by uneven force, such as drill bit breakage or workpiece flying out, etc., and solves the problem that the flexible clamp has relatively poor rigidity and cannot effectively ensure the dimensional stability of the clamp like a rigid clamp. This will cause the clamp to deform due to force or temperature changes during processing, thereby affecting the processing accuracy of the workpiece.

The paraffin in the paraffin fixing mechanism falls to the top of the pressing row due to gravity. The sliding drive motor is reversed to reset the supporting slide plate, and the supporting slide plate drives the pressing plate to reset at the same time. At this time, the pressing row electric telescopic cylinder is extended, and the pressing row electric telescopic cylinder pushes the pressing row upward to make the pressing row fit with the pressing plate, and the paraffin is cut through the pressing row. Cut, after cutting, part of the paraffin falls to the top of the paraffin heating mechanism, the pressing row electric telescopic cylinder is contracted to reset the pressing row, the sliding drive motor is started to rotate forward, the supporting slide plate drives the pressing plate to move into the pressing plate groove, the second electromagnet block is turned on, the second electromagnet block is energized and connected with the second magnet block and the magnetic attraction, so that the pressing row stripping template is adsorbed under the pressing plate, and the sliding drive motor is reversed to transfer the pressing row stripping template to the top of the pressing row, and the pressing row electric telescopic cylinder is extended to make the pressing row and the pressing row stripping template fit, so that the paraffin remaining in the pressing row hole groove is pushed out and falls above the paraffin heating mechanism.

[0039] A drilling method of a drilling device for processing a torque control arm, comprising the following steps:

[0040] Step 1: Start the vacuum pump 22 and open the valve of the suction pipe 23. As the vacuum pump 22 sucks air, the air in the paraffin fixing mechanism 2 is discharged. After the air is emptied, the valve of the suction pipe 23 is closed. The paraffin heating mechanism 28 is opened to heat the paraffin in the paraffin heating chamber 27. The added paraffin is liquefied. The liquefied paraffin is pumped by the liquid pump and injected into the paraffin fixing mechanism 2 through the paraffin filling pipe 29. When the paraffin capacity in the paraffin fixing mechanism 2 is half full, the valve of the paraffin filling pipe 29 is closed.

[0041] Step 2: Clamp the torque control arm, adjust the front and rear position of the drilling drive frame 5 through the first screw 4, adjust the left and right position of the mounting seat 7 through the second screw 6, adjust the height of the vacuum suction cup clamping mechanism 12 through the vacuum suction cup clamping mechanism screw 9, and drive the vacuum suction cup clamping mechanism rotating block 14 to rotate and extend the vacuum suction cup clamping mechanism electric telescopic cylinder 15 through the motor in the vacuum suction cup clamping mechanism sliding block 13 to allow the vacuum suction cup clamping mechanism 12 to clamp the torque control arm and then place it on the paraffin fixing mechanism 2, so that the paraffin fixing mechanism 2 is completely fitted with the lower surface of the torque control arm, and wait for the paraffin to cool and set. The wax is completely fitted to the lower surface of the torque control arm, so that the lower part of the torque control arm is evenly stressed, and the flexible pressing of the vacuum suction cup clamping mechanism 12 is combined to ensure the stability of the drilling process and reduce the shaking and shaking caused by uneven force. The contact force between the drill bit and the workpiece is balanced, which helps to reduce the deviation caused by uneven force. The uniform force can significantly reduce the error in the drilling process. The uniform force clamping method can reduce the friction and wear between the drill bit and the workpiece, thereby reducing the risk of damage to the drill bit and the workpiece. The uniform force clamping method can reduce unexpected situations caused by uneven force, such as drill bit breakage or workpiece flying out.

[0042] Step 3: After the paraffin is shaped, the height of the drilling turntable mechanism 10 is adjusted by the drilling turntable mechanism lead screw 8, and then the corresponding drill bit 11 is selected according to the thickness of the torque control arm and the required process, and the drill bit fixing disk drive motor 41 is started. The output end of the drill bit fixing disk drive motor 41 drives the drill bit fixing disk drive gear 40 to rotate, and the drill bit fixing disk drive gear 40 drives the drill bit fixing disk 33 provided with an internal gear 42 to rotate outside the drilling motor fixing plate 34 through meshing until the required drill bit is located below the drilling motor 35, and the movable coupling block lead screw 43 is adjusted to drive the movable coupling block 38 provided with the movable coupling block sliding end 44 to move toward the fixed coupling block 36, so that the coupling block limit block 45 is adapted to the coupling block limit block groove 46, and then the first electromagnet block is connected, and the first magnet block and the first electromagnet block are magnetically attracted to each other, completing the transmission connection between the drilling motor 35 and the drill bit 11, and starting the drilling motor 35 to drive the drill bit 11 to rotate, thereby drilling the torque control arm;

[0043] Step 4: When the style of the torque control arm changes, the sliding drive motor 18 is started to rotate forward, and the sliding drive motor 18 drives the supporting slide plate driving gear 19 to rotate. The supporting slide plate driving gear 19 drives the supporting slide plate 16 provided with the supporting slide plate gear row 26 to slide to the side away from the paraffin fixing mechanism 2 through meshing. The paraffin in the paraffin fixing mechanism 2 falls to the top of the pressing row 30 due to gravity. The sliding drive motor 18 is reversed to reset the supporting slide plate 16, and the supporting slide plate 16 drives the pressing plate 20 to reset at the same time. At this time, the pressing row electric telescopic cylinder 32 is extended, and the pressing row electric telescopic cylinder 32 pushes the pressing row 30 upward to fit the pressing row 30 with the pressing plate 20, and the paraffin is pressed by the pressing row 30. The cutting is performed, and part of the paraffin falls onto the paraffin heating mechanism 28 after cutting.

10. A drilling method based on the drilling device for torque control arm processing according to claim 9, characterized in that: The following steps are involved: Step 1: Start the vacuum pump (22) and open the valve of the suction pipe (23). As the vacuum pump (22) sucks air, the air in the paraffin fixing mechanism (2) is discharged. After the air is discharged, the valve of the suction pipe (23) is closed. The paraffin heating mechanism (28) is opened to heat the paraffin in the paraffin heating chamber (27). The added paraffin is liquefied. The liquefied paraffin is extracted by the liquid pump and injected into the paraffin fixing mechanism (2) through the paraffin filling pipe (29).

The contact force between the drill bit and the workpiece is balanced, which helps to reduce the deviation caused by uneven force. The uniform force can significantly reduce the error in the drilling process. The uniform force clamping method can reduce the friction and wear between the drill bit and the workpiece, thereby reducing the risk of damage to the drill bit and the workpiece. The uniform force clamping method can reduce unexpected situations caused by uneven force, such as drill bit breakage or workpiece flying out. Step 3: After the wax is shaped, the height of the drilling turntable mechanism (10) is adjusted by the lead screw (8) of the drilling turntable mechanism, and then the corresponding drill bit (11) is selected according to the thickness of the torque control arm and the required process, and the drill bit fixing plate driving motor (41) is started.

At this time, the pressing row electric telescopic cylinder (32) is extended, and the pressing row electric telescopic cylinder (32) pushes the pressing row (30) upward, so that the pressing row (30) fits with the pressing plate (20).
