A plurality of auxiliary reset components 7 are arranged between the support member 5 and the grinding assembly 4. An embedded groove 33 is formed on the side of the transition portion 34 close to the tool shank portion. An auxiliary grinding ring 6 is fixedly sleeved in the embedded groove 33. It should be noted that the drilling assembly 2 further includes a driving assembly.

Therefore, they will not be elaborated in the present invention.

[0038] Among them, the grinding assembly 4 includes a fixed block 41. On both sides of one end of the fixed block 41, extension blocks 44 are symmetrically and fixedly installed.

[0039] Among them, a rotating cavity is formed in the transition portion 34 at the position of the extension block 44. And a first fixing shaft is inserted through the extension block 44 and the fixed block 41.

[0041] Moreover, a third sliding cavity 314 is formed in the transition part 34 at the position of the first clamping component 45. The width of the third sliding cavity 314 is greater than the diameter of the first spherical moving block. A second limiting component 93 and a third limiting component 94 are sequentially arranged in the third sliding cavity 314.

One side of the second fixed rod part is connected to the support member 5, and a second spherical moving block is fixedly installed on the other side of the second fixed rod part.

[0044] Furthermore, a second sliding cavity 313 is formed in the transition part 34 at the position of the second clamping component 51. The width of the second sliding cavity 313 is greater than the diameter of the second spherical moving block. A first sliding cavity 311 is formed in the transition part 34 at the position of the third clamping component 53. The width of the first sliding cavity 311 is greater than the diameter of the second spherical moving block.

[0045] Moreover, third elastic arc pieces 95 are symmetrically arranged at both ends of the second clamping component 51 on the side close to the extending clamping block 44 in the second sliding cavity 313, and fourth elastic arc pieces 96 are symmetrically arranged at both ends of the second clamping component 51 on the other side in the second sliding cavity 313.

[0046] Moreover, at both ends of the first sliding cavity 311 on the side close to the third elastic arc piece 95, first elastic arc pieces 91 are symmetrically arranged, and at one end of one side in the first sliding cavity 311, an auxiliary limiting component 8 is arranged. The auxiliary limiting component 8 includes a limiting plate, on one side of the limiting plate, a clamping convex block 82 is installed. The cross-section of the clamping convex block 82 is triangular. In the transition part 34, a cavity is opened at the position of the limiting plate. A clamping through hole is penetrated between the cavity and the first sliding cavity 311 in the transition part 34. The cross-sectional area of the clamping through hole is the same as the cross-sectional area of the clamping convex block 82. On the other side of the limiting plate, a plurality of second springs 81 are installed at equal distances, and the other side of the second springs 81 is connected to the inner wall of the cavity.

[0047] Meanwhile, it is worth mentioning that when the first spherical movable block is located in the third sliding cavity 314 and against the inner wall of the side close to the handle part, the second clamping component 51 is located on one side of the third elastic arc piece 95 and away from the extended clamping block 44, and the third clamping component 53 is located on one side of the first elastic arc piece 91 and away from the extended clamping block 44.

When the first spherical movable block is located in the third limiting component 94, the second clamping component 51 is located on one side of the third elastic arc piece 95 and away from the extended clamping block 44, and the third clamping component 53 is located on one side of the first elastic arc piece 91 and away from the extended clamping block 44.

[0048] Moreover, the auxiliary reset component 7 includes a fixed seat 71. On one side of the fixed seat 71, an arc-shaped ejector rod 72 is connected. On one side of the arc-shaped ejector rod 72, a limiting ring 75 is connected. On one side of the limiting ring 75, a flexible steel rope body 76 is connected. The other side of the flexible steel rope body 76 is connected to the fixed block 41 through a pull ring. The specific structure and working principle of the pull ring are both existing technologies already disclosed in the current market and do not belong to the main technical problems to be solved by this technical solution. Therefore, this technical solution will not be elaborated in detail.

[0049] On one side of the fixed seat 71 and outside the arc-shaped ejector rod 72, a first spring 73 is connected. The other side of the first spring 73 is connected to a movable ring 74, and a through hole is penetrated through the arc-shaped ejector rod 72 in the movable ring 74.

[0050] Moreover, in the transition part 34, a limiting cavity 312 is opened on one side of the movable cavity 32 and at the position of the movable ring 74. In the transition part 34, an auxiliary sliding groove is opened on one side of the limiting cavity 312 and at the position of the limiting ring 75. In the transition part 34, an auxiliary sliding cavity is opened on one side of the auxiliary sliding groove and at the position of the flexible steel rope body 76, and the diameter of the auxiliary sliding cavity is larger than the diameter of the flexible steel rope body 76.

[0051] Meanwhile, a magnetic attraction bump 54 is fixedly installed on one side of the top of the support member 5 located at the fixed block 41. A limiting bump 10 is fixedly installed on the inner wall of the movable cavity 32 above the second fixed shaft. A magnetic groove 101 is formed at the bottom of the limiting bump 10 at the position of the magnetic attraction bump 54. The length of the magnetic groove 101 is greater than the length of the limiting bump 10, and the inner wall of the magnetic groove 101 is made of a magnetic material that adsorbs to the magnetic attraction bump 54. The magnetic groove 101 is magnetically adsorbed and connected to the magnetic attraction bump 54.

[0052] Moreover, it is worth mentioning that when the second clamping assembly 51 is located on one side of the third elastic arc piece 95 and away from the extension block 44, and the third clamping assembly 53 is located on one side of the first elastic arc piece 91 and away from the extension block 44, the magnetic attraction bump 54 of the support member 5 is located in the magnetic groove 101, and the magnetic groove 101 is magnetically adsorbed and connected to the magnetic attraction bump 54.

[0053] Moreover, it should be noted that the outer wall of the auxiliary grinding ring 6 is flush with the outer wall of the drill body part of the drill bit body 31.

[0054] Among them, it should be noted that the first spring 73 is made of spring steel spring after heat treatment.

[0055] In the present invention, the composite machining tool body 1 clamps the aluminum workpiece to be processed, and then the driving assembly of the drilling assembly 2 drives the drill bit assembly 3 to rotate, and at the same time, the drill bit body 31 moves towards the aluminum workpiece to be processed.

[0056] In the normal state, that is, when the drill bit body 31 is not in use, when 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 the extension block 44, the third clamping assembly 53 is located on one side of the first elastic arc piece 91 and away from the extension block 44, the magnetic attraction bump 54 of the support member 5 is located in the magnetic groove 101, and the magnetic groove 101 is magnetically adsorbed and connected to the magnetic attraction bump 54. At this time, the support member 5 plays a certain auxiliary supporting role for the fixed block 41. And because the cross section of the support member 5 is triangular, and the triangle has good stability, it can ensure the stability of the support for the fixed block 41. Through the magnetic adsorption connection between the magnetic attraction bump 54 and the magnetic groove 101, the stability of the support for the fixed block 41 is further ensured.

[0057] When the drill bit body 31 moves towards the aluminum workpiece, first, the drill tip and the drill body are used to drill holes in the aluminum workpiece. During the gradual descent of the drill bit body 31, the fixing block 41 and the grinding convex block 42 gradually move into the movable cavity 32 under the influence of the hole. And until the fixing block 41 and the grinding convex block 42 are located inside the movable cavity 32 and on the side close to the tool handle part. At the same time, at this time, the first spherical movable block is located on the inner wall of the third sliding cavity 314 and on the side close to the tool handle part, the second clamping assembly 51 is located on one side of the fourth elastic arc piece 96 and close to the extended clamping block 44, the third clamping assembly 53 is located on one side of the clamping convex block 82 and far from the extended clamping block 44, and the support member 5 remains unchanged.

[0058] When the drill bit body 31 continues to move downward along the hole of the aluminum workpiece, and the auxiliary grinding ring 6 gradually moves into the hole and moves inside the hole, the inner wall of the hole is ground by the auxiliary grinding ring 6. And at this time, the fixing block 41 and the grinding convex block 42 are located inside the movable cavity 32 and on the side close to the tool handle part.

[0059] When the drill bit body 31 continues to move downward along the hole of the aluminum workpiece, and after the transition part 34 passes through the hole of the aluminum workpiece, the fixing block 41 moves outward of the movable cavity 32 under the action of the first clamping assembly 45 and its own gravity. Then, the driving assembly of the drilling assembly 2 drives the drill bit assembly 3 to rotate, and at the same time, the drill bit body 31 moves towards the aluminum workpiece to be processed. At this time, the top of the grinding convex block 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 inside the second limiting assembly 93. Then, the movement of the drill bit assembly 3 is stopped. When the top of the grinding convex block 42 fits with the top of the transition part 34, only the drill bit body 31 is rotated, so as to grind the edge protrusions and burrs formed during the hole drilling process at the bottom of the aluminum workpiece by the grinding convex block 42.

[0060] After the edge protrusions and burrs formed during the hole drilling process at the bottom are ground, the driving assembly of the drilling assembly 2 continues to drive the drill bit assembly 3 to rotate, and at the same time, the drill bit body 31 moves into the hole of the aluminum workpiece to be processed. When the transition part 34 gradually moves into the hole, the fixing block 41 moves downward under the action of the first fixed shaft and gradually moves into the movable cavity 32 until it is located inside the movable cavity 32 and on the side close to the drill body part. At the same time, at this time, the first spherical movable block is located inside the third limiting assembly 94, and the second clamping assembly 51 is located on one side of the third elastic arc piece 95 and far from the extended clamping block 44, and the third clamping assembly 53 is located on one side of the first elastic arc piece 91 and far from the extended clamping block 44.

[0061] Meanwhile, the support member 5 drives the arc-shaped ejector rod 72 to slide into the auxiliary chute, and drives the movable ring 74 and the first spring 73 to move into the limiting cavity 312, and the movable ring 74 is 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 through hole, the support member 5 moves away from the limiting cavity 312 under the action of the first spring 73. Since there are a plurality of auxiliary reset components 7 provided between the support member 5 and the grinding assembly 4, when the support member 5 moves away from the limiting cavity 312, the fixed block 41 is assisted by the arc-shaped ejector rod 72 and the flexible steel rope body 76, so that the fixed block 41 moves into the movable cavity 32 and towards the side of the tool handle part, and the fixed block 41 is located outside the transition part 34.

[0063] And when the support member 5 moves away from the limiting cavity 312 under the action of the first spring 73, the first spherical movable block moves along the inner wall of the third sliding cavity 314 towards the side of the tool handle part, the second clamping component 51 moves towards the side of the fourth elastic arc piece 96 and close to the extended clamping block 44, the third clamping component 53 moves towards the side of the clamping convex block 82 and away from the extended clamping block 44. At the same time, the magnetic attraction convex block 54 of the support member 5 is located in the magnetic groove 101, and the magnetic groove 101 is magnetically adsorbed and connected with the magnetic attraction convex block 54.

[0064] Then, continue to drive the drill bit assembly 3 to rotate through the drive assembly of the drilling assembly 2. At the same time, the drill bit body 31 moves into the through hole of the aluminum workpiece to be processed until the grinding strip 43 at the bottom of the fixed block 41 is basically in contact with the top of the through hole of the aluminum workpiece. Then, drive the drill bit assembly 3 to rotate through the drive assembly of the drilling assembly 2, and then grind the top of the through hole of the aluminum workpiece through the grinding strip 43. At the same time, after grinding, then drive the drill bit assembly 3 to rotate through the drive assembly of the drilling assembly 2. At the same time, the drill bit body 31 moves into the through 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 tool handle part, and the first spherical movable block is located in the second limiting component 93, or the first spherical movable block is located on one side of the second limiting component 93 and away from the third limiting component 94.

[0065] Then, control to turn off the drive assembly of the drilling assembly 2 to make the drill bit body 31 away from the aluminum workpiece. The whole operation process simplifies the processing flow of the aluminum workpiece, reduces the clamping times and processing time. At the same time, during the through-hole drilling process of the aluminum workpiece, the inner wall, top and bottom of the through hole, as well as the edge protrusions and burrs formed during the drilling process, are ground, improving the processing efficiency of the aluminum workpiece.

[0066] In the present invention, through the cooperative setting of the grinding assembly 4, the support member 5, and the auxiliary reset assembly 7 within the transition portion 34 and the second limiting assembly 93, the third limiting assembly 94, the first elastic arc piece 91, the third elastic arc piece 95, the fourth elastic arc piece 96, and the auxiliary limiting assembly 8, when a user performs a through-hole drilling process on an aluminum workpiece, the inner wall, the top, and the bottom of the hole can be ground for the edge protrusions and burrs formed during the drilling process, simplifying the processing flow of the aluminum workpiece, reducing the number of clamping operations and the processing time, and improving the processing efficiency of the aluminum workpiece.

[0067] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
