Then, first, by controlling the second motor to work, the position of the support seat is adjusted, so as to realize the adjustment of the lateral distance between the tool rest on the support plate and the automobile steering arm bracket. Then, the longitudinal distance between the tool rest and the automobile steering arm bracket is adjusted by the third motor. The tool is fixed on the tool rest. Then, the switch of the first motor is turned on, and the first motor drives the transmission shaft to rotate. Then, through the mounting seat and the special fixture, the automobile steering arm bracket workpiece is driven to rotate, and the rough turning operation is completed in cooperation with the tool on the tool rest. Then, the support seat is driven to move by the second motor, and the support plate is driven by the support seat to move away from the automobile steering arm bracket workpiece. At this time, the height of the connecting plate is adjusted by the multi-stage electric telescopic rod, so that the induction coil is lowered to the position of the automobile steering arm bracket workpiece. Then, the support seat is driven to move by the second motor, so that the automobile steering arm bracket workpiece passes through the induction coil to perform quenching work on the automobile steering arm bracket workpiece. After the quenching work is completed, the induction coil is reset by the multi-stage electric telescopic rod and the second motor. Finally, the distance between the fine grinding head and the automobile steering arm bracket workpiece is adjusted by the third motor for fine grinding processing, realizing that the device can perform integrated operations of rough turning, quenching and fine grinding on the workpiece.

Therefore, during the process of adjusting the position of the fine grinding head, the third motor operates to drive the second lead screw to rotate, causing the support seat to move. When the signal intensity of the pressure sensor is the maximum, the coaxiality between the fine grinding head and the workpiece of the automotive steering arm bracket is the highest. Furthermore, the position of the fine grinding head can be automatically adjusted by controlling the third motor through the controller. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Working principle: During use, fix the special fixture of the vehicle steering arm bracket on the mounting seat 13, then fix the vehicle steering arm bracket on the special fixture. Next, first control the second motor 5 to work. The second motor 5 drives the first lead screw 8 to rotate through the first transmission wheel 7 and the first transmission belt 6. During the rotation of the first lead screw 8, the first transmission seat 26 is driven to move in cooperation with the first bushing 27 on the first transmission seat 26. With the assistance of the first guide rail 10 and the first guide block 28, the support seat 12 is driven to move, and the position of the support seat 12 is adjusted, thereby realizing the adjustment of the lateral distance between the tool rest 30 on the support plate 21 and the vehicle steering arm bracket. Then, turn on the switch of the third motor 24. The third motor 24 drives the second lead screw 25 to rotate. Under the action of the second bushing 41 on the second transmission seat 42, the second transmission seat 42 is driven to move. With the cooperation of the second guide rail 19 and the second guide block 20, the support plate 21 is moved;

[0041] Adjust the longitudinal distance between the tool rest 30 and the vehicle steering arm bracket. Fix the tool on the tool rest 30. Then, turn on the switch of the first motor 4. The first motor 4 drives the transmission shaft to rotate, and then drives the vehicle steering arm bracket workpiece to rotate through the mounting seat 13 and the special fixture, and cooperates with the tool on the tool rest 30 to complete the rough turning operation;

[0042] Then, drive the support seat 12 away from the vehicle steering arm bracket through the second motor 5, and drive the support plate 21 away from the vehicle steering arm bracket workpiece through the support seat 12. At this time, adjust the height of the connecting plate 16 through the multi-stage electric telescopic rod 23, so that the induction coil 17 is lowered to the position of the vehicle steering arm bracket workpiece. Under the action of the guide rod 15, the connecting plate 16 has a high stability during the movement process;

[0043] Then, drive the support seat 12 to move through the second motor 5, so that the vehicle steering arm bracket workpiece passes through the induction coil 17 to perform quenching work on the vehicle steering arm bracket workpiece. After the quenching work is completed, drive the induction coil 17 to reset through the multi-stage electric telescopic rod 23 and the second motor 5;

[0044] Finally, adjust the position of the support plate 21 through the third motor 24, and then adjust the distance between the fine grinding head 32 and the vehicle steering arm bracket workpiece. Turn on the switch of the fourth motor 40. The fourth motor 40 drives the rotating shaft 37 to rotate through the two second transmission wheels 39 and the second transmission belt 38, and then drives the fine grinding head 32 to rotate for fine grinding processing, realizing that this device can perform rough turning, quenching and fine grinding on the workpiece. During rough turning, quenching and fine grinding, there is no need to perform a large amount of loading and unloading work on the vehicle steering arm bracket, improving the work efficiency;

[0045] During the process of adjusting the movement of the support plate 21 by the third motor 24, the support plate 21 drives the rotating shaft 37 to move through the grinding seat 31. During the movement of the rotating shaft 37, the sleeve rod 36 is driven to slide along the sleeve 33. When the axial direction of the rotating shaft 37 and the axial direction of the mounting seat 13 are not collinear, during the movement of the sleeve rod 36, the compressed second spring 35 gradually returns, causing the signal intensity of the pressure sensor 34 to decrease.

[0046] Therefore, during the process of adjusting the position of the fine grinding head 32, when the signal intensity of the pressure sensor 34 is the maximum, the coaxiality between the fine grinding head 32 and the workpiece of the automotive steering arm bracket is the highest. Furthermore, the position adjustment of the fine grinding head 32 can be automatically performed by controlling the third motor 24 through the controller.
