The clamping key 53 is clamped in the clamping groove to guide the connecting handle 52, and after the positioning plate 41 is clamped in the positioning groove, the positioning plate 41 is fixed in the positioning groove through the positioning bolt 42 to complete the connection and fixation of the cutter head 5 and the clamp 4. When the cutter head 5 is used, the positioning plate 41 and the clamping key 53 both play a positioning role and bear the torque force generated by the rotation of the cutter head 5.
After the tool 51 and the cutter head 5 are installed, the telescopic rod 1 and the driving machine 3 are controlled to work, and the driving machine 3 drives the cutter head 5 to rotate through the clamp 4, so that the tool 51 installed on the cutter head 5 cuts and processes a workpiece. Before the cutter 51 contacts with the workpiece, the connecting plate 69 contacts with the surface of the workpiece, and as the cutter head 5 continues to move downwards, the connecting plate 69 pushes the moving plate 64 to move upwards through the guide rod 63, and the extrusion plate 61 extrudes the pressure detection module 65. The pressure received by the pressure detection module 65 detects the distance between the tool 51 and the workpiece, thereby facilitating control of the movement of the cutter head 5 in the Z-axis.
When the cutter head 5 is cut from the side surface of the workpiece, the end of the long plate 7 is firstly contacted with the surface of the workpiece and moves along with the cutter head 5 on the X axis or the Y axis. The long plate 7 slides to the upper part of the workpiece through the inclined surface at the end part, and the long plate 7 drives the connecting plate 69 to displace after being stressed, so that the pressure detection module 65 can detect the distance between the cutter 51 and the workpiece when the cutter head 5 is cut into the workpiece from the side surface conveniently.
A PLC controller is externally provided, and a receiving module communicating with the communication module 67 is connected to the PLC controller, and the pressure applied to the pressure detection module 65 is transmitted into the receiving module through the communication module 67. The received information is processed by the PLC controller, and if the pressure received by the pressure detection module 65 satisfies the offset of the tool 51 in the Z axis during operation, the telescopic rod 1 stops operating. Correspondingly, if the pressure that pressure detection module 65 received is less or not receive pressure, PLC controller control telescopic link 1 continues to extend and promotes blade disc 5 and move up and down on the Z axle, if the pressure that pressure detection module 65 received is too big, PLC controller control telescopic link 1 shortens and drives blade disc 5 and move up on the Z axle, until the pressure that pressure detection module 65 received satisfies working range. By means of automatic detection, effective cutting of the tool 51 on the workpiece is guaranteed, radial runout caused by over-deep cutting of the tool 51 is avoided, and the machining precision of the workpiece is guaranteed;
when the cutter head 5 rotates, the long plate 7 is driven to rotate by taking the guide rod 63 as an axis, the cutter 51 on the cutter head 5 cuts the surface of a workpiece, and the grinding plate 72 on the lower side of the long plate 7 grinds the surface cut by the cutter 51, so that the flatness and smoothness of the cut surface are ensured;
during the high-speed rotation process of the cutter head 5, the airflow is restricted by the gas collecting box 81 to enter the flow guide holes 8, the airflow in the flow guide holes 8 enters the cylinder 6 through the air inlet holes, and the airflow moves from the upper part of the inner cavity of the cylinder 6 to the lower part of the inner cavity of the cylinder 6 and is sprayed out of the cylinder 6 through the air outlet holes. The spun air current is spout in from blade disc 5 through the constant head tank notch, and the air current cools down the subassembly in the barrel 6, and the sweeps that the cutting produced when the air current is spout in from the constant head tank are cleared up, avoid the sweeps adhesion to gather in blade disc 5 below or the mounting groove of installation cutter 51.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
