[0040] Specifically, by cooperating the motor 501 with the driving gear 502, after the motor 501 is started, its output end drives the driving gear 502 to rotate continuously, since the driving gear 502 is an incomplete gear, it is accurately meshed with the driven gear 503 during rotation, thereby driving the driven gear 503 to rotate according to a certain law, and the rotating rod 505 fixedly connected to the inner side of the driven gear 503 rotates accordingly.

[0042] Specifically, through cooperation of the electrostatic column 701, the fixed cylinder 703 and the reinforcing assembly, when static electricity is generated in processing, the wire 708 on the electrostatic column 701 guides the static electricity out; in the reinforcing assembly, the fixed rod 702 is inserted into the fixed cylinder 703, the plug column 705 cooperates with the plug hole 707 on the outside of the fixed cylinder 703 under the action of the spring 706, and the electrostatic column 701 is stabilized, so that the static electricity in processing is effectively eliminated, the scattered debris due to static electricity is prevented, and the processing environment is kept clean and the processing precision is ensured.

[0043] The electrostatic column 701 is detached in the following manner: the plug column 705 is pressed into the installation groove 704 in the inside of the fixed rod 702, so as to overcome the elastic force of the spring 706 and be retracted into the installation groove 704, at this time, the plug column 705 is separated from the plug hole 707 on the outside of the fixed cylinder 703, and the electrostatic column 701 together with the fixed rod 702 can be pulled out from the inside of the fixed cylinder 703 to complete the detachment.

[0045] Working principle: first, the distance between the three fastening bolts 602 on the stabilizing mechanism 6 is adjusted according to the size of the workpiece, so that the fastening bolt 602 close to the outermost side is slightly loose to facilitate fixing the workpiece, then the workpiece is placed in the placement shell 601, and then the outermost fastening bolt 602 is rotated to abut against the workpiece, and the other two fastening bolts 602 form three fastenings, so that the workpiece is stably fixed in the placement shell 601.

[0046] Then the motor 501 is started, and the output end of the motor 501 drives the driving gear 502 to rotate. Since the driving gear 502 is an incomplete gear, and the driving gear 502 rotates one circle, the driven gear 503 rotates one fourth circle, and the rotating rod 505 rotates, and the rotating rod 505 drives the cross plate 4 to rotate when the rotating rod 505 rotates, the guide rod 506 at the end of the cross plate 4 slides in the guide groove 507 on the top of the machining table 1, and the cross plate 4 is guided to rotate, and the stability of the cross plate 4 is ensured.

[0047] With the rotation of the cross plate 4, the workpiece is first rotated in the first machining area, the drill 3 installed at the bottom of the fixed plate 2 starts to work, and the workpiece in the machining area is machined, when a deep hole machining is completed, the motor 501 is started again, and then the driving gear 502 is driven to rotate, and then the cross plate 4 is rotated again, and the workpiece is moved to the next deep hole machining, when the workpiece completes multiple deep hole machining, and returns to the position where the workpiece is placed, the workpiece can be taken out by rotating the outermost fastening bolt 602 in the reverse direction, and then the unprocessed workpiece is placed in the placing shell 601 again, and the above-mentioned action of fixing the workpiece is repeated, and the next round of machining is carried out.

[0048] In the machining process, since static electricity is generated during machining, the debris in the drill hole is scattered, and the static electricity elimination mechanism 7 starts to work, the wire 708 on the static electricity column 701 leads out static electricity, and the reinforcing assembly in the fixed rod 702 ensures the stability of the static electricity column 701, specifically, the fixed rod 702 is inserted into the fixed cylinder 703, and then the plug-in column 705 is inserted into the plug hole 707 outside the fixed cylinder 703 under the action of the spring 706, so that the static electricity column 701 is stably installed in the fixed cylinder 703, thereby effectively eliminating the static electricity generated during machining, and ensuring that the debris in the machining process will not be scattered.

[0049] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
