Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy drilling technology, and more specifically, to a drilling device for aluminum alloy processing. Background Technology

[0002] A drilling machine is a machine tool that primarily uses a drill bit to machine holes in a workpiece. Typically, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. Drilling machines have a simple structure, relatively low machining accuracy, and can drill through holes and blind holes. By changing special tools, they can also perform reaming, countersinking, boring, or tapping. During machining, the workpiece remains stationary while the tool moves, aligning its center with the hole center and rotating (the main motion). The key characteristic of a drilling machine is that the workpiece is stationary while the tool rotates. Aluminum alloys often require drilling during machining.

[0003] In the process of drilling some aluminum alloy tubes, it is necessary to drill holes in the same location and ensure that the included angle between the corresponding metal tube axes of two adjacent holes is 90°. Therefore, before drilling, the workers need to measure and mark the hole positions on the tube body, which affects the drilling efficiency. So we propose a drilling device for aluminum alloy processing to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a drilling device for aluminum alloy processing, which is easy to operate, has high positioning accuracy, and improves drilling efficiency.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A drilling device for aluminum alloy processing includes a cabinet, a base mounted on the cabinet, and a bench drill fixed on the base. A rotating shaft is rotatably connected to the inner side of the base. A boss is integrally formed on the outer wall of the rotating shaft. A first limiting rod is fixedly connected to the boss, and two first limiting rods are provided. One end of the rotating shaft has an internal threaded hole. The rotating shaft has a first through hole corresponding to the drill rod of the bench drill, and two sets of the first through holes are provided. Guide grooves are provided on the outer wall of the rotating shaft on both sides of the first through hole.

[0009] A second limiting rod is provided directly below the rotating shaft, with its end fixedly connected to the base, and the second limiting rod abuts against one of the first limiting rods;

[0010] A positioning sleeve is fitted on the outer side of the rotating shaft. A second through hole corresponding to the first through hole is opened on the positioning sleeve. A guide flange integrally formed on the inner wall of the positioning sleeve and forming an embedded structure with the guide groove.

[0011] An aluminum alloy tube is fitted onto the outer side of the positioning sleeve;

[0012] A clamping block that engages with the rotating shaft is detachably connected to one side of the aluminum alloy tube.

[0013] A hexagonal bolt with its end tightly fitted to the clamping block is screwed into the internal threaded hole.

[0014] Furthermore, a storage platform is installed on the top edge of the cabinet, and the storage platform has storage cavities with different apertures.

[0015] Furthermore, the angle between the centerlines of the two sets of first through holes and the centerline of the rotating shaft is 90°.

[0016] Furthermore, the other end of the rotating shaft is integrally formed with a shaft head, and the shaft head is connected to the base via a bearing.

[0019] Furthermore, the clamping block has an open slot, and the inner diameter of the slot is adapted to the outer diameter of the rotating shaft.

[0020] 3. Beneficial effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] (1) In this scheme, the positioning sleeve is fitted onto the rotating shaft by sliding the guide flange with the guide groove, so that the first through hole and the second through hole correspond to each other. Then, the aluminum alloy tube is fitted onto the positioning sleeve, and the aluminum alloy tube is positioned in the radial position. The clamping block is engaged on the rotating shaft. By installing and tightening the hexagonal bolt at the internal thread hole, the end of the hexagonal bolt abuts against the clamping block, thereby clamping the aluminum alloy tube in the axial direction. Before drilling, one of the first limit rods abuts against the second limit rod, so that the drill rod on the bench drill corresponds to the first through hole. By operating the bench drill, the drill rod cooperates with the second through hole to drill through the aluminum alloy tube. Then, the bench drill is reset and the rotating shaft is rotated counterclockwise, so that the other first limit rod abuts against the second limit rod. At this time, the aluminum alloy tube is rotated 90° synchronously. Then, the bench drill is operated to drill again to complete the drilling of the aluminum alloy tube. The operation is convenient, the positioning accuracy is high, and the drilling efficiency is improved.

[0023] (2) This solution improves applicability by placing positioning sleeves with different outer diameters but the same inner diameter inside the storage cavities with different apertures to position aluminum alloy tubes of different diameters. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figure 1-5 A drilling device for aluminum alloy processing includes a cabinet 1, a base 2 mounted on the cabinet 1, and a bench drill 3 fixed on the base 2. A rotating shaft 4 is rotatably connected to the inner side of the base 2. A boss 5 is integrally formed on the outer wall of the rotating shaft 4. A first limiting rod 7 is fixedly connected to the boss 5, and two first limiting rods 7 are provided. One end of the rotating shaft 4 is provided with an internal threaded hole 9. A first through hole 6 corresponding to the drill rod of the bench drill 3 is provided on the rotating shaft 4, and two sets of first through holes 6 are provided. Guide grooves 8 are provided on the outer wall of the rotating shaft 4 on both sides of the first through hole 6.

[0034] A second limiting rod 11 with its end fixedly connected to the base 2 is provided directly below the rotating shaft 4, and the second limiting rod 11 abuts against one of the first limiting rods 7;

[0035] A positioning sleeve 12 is fitted on the outer side of the rotating shaft 4. A second through hole 13 corresponding to the first through hole 6 is opened on the positioning sleeve 12. A guide flange 14 integrally formed on the inner wall of the positioning sleeve 12 and forming an embedded structure with the guide groove 8.

[0036] An aluminum alloy tube 15 is fitted on the outer side of the positioning sleeve 12;

[0037] A clamping block 16 that engages with the rotating shaft 4 is detachably connected to one side of the aluminum alloy tube 15.

[0038] Hexagonal bolts 17, whose ends fit tightly against clamping blocks 16, are screwed into the internal threaded holes 9.

[0039] It should be noted that, in use, the drilling device for aluminum alloy processing firstly slides the guide flange 14 in conjunction with the guide groove 8 to place the positioning sleeve 12 onto the rotating shaft 4, simultaneously aligning the first through hole 6 and the second through hole 13. Then, the aluminum alloy tube 15 is placed on the positioning sleeve 12, positioning it radially. The clamping block 16 is then engaged with the rotating shaft 4. A hexagonal bolt 17 is installed at the internal threaded hole 9 and tightened, with the end of the hexagonal bolt 17 abutting against the clamping block 16, thereby axially clamping the aluminum alloy tube 15. Before drilling, this ensures that… One of the first limiting rods 7 and the second limiting rod 11 abut against each other, so that the drill rod on the bench drill 3 corresponds to the first through hole 6. By operating the bench drill 3 to drill down, the drill rod cooperates with the second through hole 13 to drill through the aluminum alloy tube 15. Then, the bench drill 3 is reset and the rotating shaft 4 is rotated counterclockwise, so that the other first limiting rod 7 abuts against the second limiting rod 11. At this time, the aluminum alloy tube 15 is rotated 90° synchronously. Then, the bench drill 3 is operated to drill down again to complete the drilling of the aluminum alloy tube 15. The operation is convenient, the positioning accuracy is high, and the drilling efficiency is improved.

[0040] like Figure 1 A storage platform 19 is installed on the top edge of the cabinet 1, and the storage platform 19 has storage cavities 20 with different apertures.

[0041] It should be noted that by placing positioning sleeves 12 with different outer diameters but the same inner diameter inside the storage cavities 20 with different apertures, aluminum alloy tubes 15 with different diameters can be positioned, thereby improving applicability.

[0042] like Figure 4 As shown, the angle between the centerlines of the two sets of first through holes 6 and the centerline of the rotating shaft 4 is 90°.

[0043] It should be noted that it can assist in the drilling of aluminum alloy tube 15 while ensuring the accuracy of the drilling angle.

[0044] like Figure 3 , Figure 4 As shown, the other end of the rotating shaft 4 is integrally formed with a shaft head 10, and the shaft head 10 is connected to the base 2 through a bearing;

[0045] It should be noted that the resistance of the rotating shaft 4 during rotation was reduced, and the rotational accuracy of the rotating shaft 4 was ensured.

[0046] like Figure 2 , Figure 3 , Figure 4 As shown, the inner diameter of the positioning sleeve 12 is adapted to the outer diameter of the rotating shaft 4, and the outer diameter of the positioning sleeve 12 is adapted to the inner diameter of the aluminum alloy tube 15.

[0047] It should be noted that positioning the aluminum alloy tube 15 in a radial position ensures the stability of the aluminum alloy tube 15 during the drilling process.

[0048] like Figure 2 , Figure 3 As shown, a protective rubber sleeve 18 corresponding to the drill rod of the bench drill 3 is installed on the top of the base 2.

[0049] It should be noted that it serves to protect the drill pipe.

[0050] like Figure 3 As shown, the clamping block 16 has an open slot, and the inner diameter of the slot is adapted to the outer diameter of the rotating shaft 4.

[0051] It should be noted that the clamping stability of the clamping block 16 is ensured during axial movement.

[0052] In use: First, the positioning sleeve 12 is fitted onto the rotating shaft 4 by sliding the guide flange 14 in conjunction with the guide groove 8, ensuring that the first through hole 6 and the second through hole 13 correspond to each other. Then, the aluminum alloy tube 15 is fitted onto the positioning sleeve 12 to position it radially. The clamping block 16 is then engaged with the rotating shaft 4. A hexagonal bolt 17 is installed at the internal threaded hole 9 and tightened, with the end of the hexagonal bolt 17 abutting against the clamping block 16, thereby clamping the aluminum alloy tube 15 axially. Before drilling, ensure… One of the first limiting rods 7 and the second limiting rod 11 abut against each other, so that the drill rod on the bench drill 3 corresponds to the first through hole 6. By operating the bench drill 3 to drill down, the drill rod cooperates with the second through hole 13 to drill through the aluminum alloy tube 15. Then, the bench drill 3 is reset and the rotating shaft 4 is rotated counterclockwise, so that the other first limiting rod 7 abuts against the second limiting rod 11. At this time, the aluminum alloy tube 15 is rotated 90° synchronously. Then, the bench drill 3 is operated to drill down again to complete the drilling of the aluminum alloy tube 15.

[0053] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
