[0054] In addition, it is worth mentioning that the first spring 73 is made of a spring steel spring after heat treatment.

[0055] In the present application, the aluminum workpiece to be machined is clamped by the composite machining machine tool body 1, then the drill bit assembly 3 is driven to rotate by the driving assembly of the drilling assembly 2, and at the same time, the drill bit body 31 is moved to the aluminum workpiece to be machined.

[0056] In the normal state, i.e., when the drill bit body 31 is not in use, the first spherical movable block is located close to the second limiting assembly 93, the fixed block 41 is located outside the transition part 34, and at this time, the second clamping assembly 51 is located on one side of the third elastic arc piece 95 and away from one side of the extended clamping block 44, the third clamping assembly 53 is located on one side of the first elastic arc piece 91 and away from one side of the extended clamping block 44, the magnetic attraction protrusion 54 of the support 5 is located in the magnetic groove 101, and the magnetic groove 101 and the magnetic attraction protrusion 54 are magnetically attracted and connected, at this time, the support 5 plays a certain auxiliary supporting role for the fixed block 41, and because the cross section of the support 5 is triangular, the triangle is stable, which can ensure the stability of the support for the fixed block 41, and the magnetic attraction between the magnetic attraction protrusion 54 and the magnetic groove 101 further ensures the stability of the support for the fixed block 41.

[0057] When the drill body 31 moves towards the aluminum workpiece, the aluminum workpiece is first punched by the drill tip and the drill body, and in the process of gradually lowering the drill body 31, the fixed block 41 and the polishing protrusion 42 gradually move into the movable cavity 32 under the influence of the hole, and until the fixed block 41 and the polishing protrusion 42 are located in the movable cavity 32 and on the side close to the shank, at the same time, the first spherical movable block is located in the third sliding cavity 314 and on the side close to the shank, the second clamping assembly 51 is located on the side of the fourth elastic arc piece 96 and close to the side of the extending clamping block 44, the third clamping assembly 53 is located on the side of the clamping protrusion 82 and away from the side of the extending clamping block 44, and the support 5 remains unchanged.

[0059] When the drill body 31 continues to move downward along the hole of the aluminum workpiece, and the transition part 34 passes through the hole of the aluminum workpiece, the fixed block 41 moves out of the movable cavity 32 under the action of the first clamping assembly 45 and its own gravity, then the drill assembly 3 is driven to rotate by the driving assembly of the drilling assembly 2, at the same time, the drill body 31 moves towards the aluminum workpiece to be processed, at this time the top of the polishing protrusion 42 gradually fits with the top of the transition part 34, so that the first clamping assembly 45 moves towards the second limiting assembly 93 and is located in the second limiting assembly 93, then the movement of the drill assembly 3 is stopped, and when the top of the polishing protrusion 42 fits with the top of the transition part 34, only the drill body 31 is rotated, so that the edge protrusion and burr formed on the bottom of the aluminum workpiece in the punching process are polished by the polishing protrusion 42.

[0060] When the polishing of the edge protrusion and burr formed on the bottom in the punching process is completed, the drill assembly 3 is driven to rotate by the driving assembly of the drilling assembly 2, at the same time, the drill body 31 moves towards the hole of the aluminum workpiece to be processed, when the transition part 34 gradually moves into the hole, the fixed block 41 moves downward under the action of the first fixed shaft and gradually moves into the movable cavity 32, until it is located in the movable cavity 32 and on the side close to the drill body, at the same time, the first spherical movable block is located in the third limiting assembly 94, and the second clamping assembly 51 is located on the side of the third elastic arc piece 95 and away from the side of the extending clamping block 44, and the third clamping assembly 53 is located on the side of the first elastic arc piece 91 and away from the side of the extending clamping block 44.

[0061] Meanwhile, the support piece 5 drives the arc-shaped top rod 72 to slide into the auxiliary sliding groove, drives the movable ring 74 and the first spring 73 to move into the limiting cavity 312, and makes the movable ring 74 located in the limiting cavity 312, and at this time, the first spring 73 is in a deformed state.

[0062] When the transition part 34 leaves the hole, the support piece 5 moves away from the limiting cavity 312 under the action of the first spring 73, and since the support piece 5 and the polishing assembly 4 are provided with a plurality of auxiliary reset assemblies 7, when the support piece 5 moves away from the limiting cavity 312, the fixed block 41 moves into the movable cavity 32 and towards the side of the handle part under the assistance of the arc-shaped top rod 72 and the flexible steel rope body 76, and the fixed block 41 is located outside the transition part 34.

[0063] When the support piece 5 moves away from the limiting cavity 312 under the action of the first spring 73, the first spherical movable block moves towards the side of the handle part along the inner wall of the third sliding cavity 314, the second clamping assembly 51 moves towards the side of the fourth elastic arc piece 96 and the side close to the extension clamping block 44, the third clamping assembly 53 moves towards the side of the clamping protrusion 82 and away from the side of the extension clamping block 44, and meanwhile, the magnetic attraction protrusion 54 of the support piece 5 is located in the magnetic groove 101, and the magnetic groove 101 and the magnetic attraction protrusion 54 are magnetically attracted and connected.

[0064] Then, the drill bit assembly 3 is continuously driven to rotate by the driving assembly of the drilling assembly 2, and at the same time, the drill bit body 31 moves into the hole of the aluminum workpiece to be processed, until the polishing strip 43 at the bottom of the fixed block 41 is basically attached to the top of the hole of the aluminum workpiece, the drill bit assembly 3 is driven to rotate by the driving assembly of the drilling assembly 2, and then the top of the hole of the aluminum workpiece is polished by the polishing strip 43, and after polishing, the drill bit assembly 3 is driven to rotate by the driving assembly of the drilling assembly 2, and at the same time, the drill bit body 31 moves into the hole of the aluminum workpiece to be processed, until the fixed block 41 moves into the movable cavity 32 and towards the side of the handle part, and the first spherical movable block is located in the second limiting assembly 93, or the first spherical movable block is located on the side of the second limiting assembly 93 and away from the side of the third limiting assembly 94.

[0065] Then, the driving assembly of the drilling assembly 2 is controlled to be turned off, and the drill bit body 31 moves away from the aluminum workpiece, and the whole operation process simplifies the processing flow of the aluminum workpiece, reduces the clamping frequency and processing time, and at the same time, the edge protrusions and burrs formed on the inner wall, top and bottom of the hole during the drilling process are polished, and the processing efficiency of the aluminum workpiece is improved.
