[0002] The drill bit is a tool that is widely used in industrial manufacturing. In the construction process of ship products, the drill bits commonly used are twist drill bits and core drill bits.

[0003] The drilling of ship turbine pump base requires drilling of deep flat-bottom holes. Due to the characteristics of twist drill bits and core drill bits, deep flat-bottom holes cannot be drilled. Deep flat-bottom holes are usually processed by machine tools, but in the drilling work of ship turbine pump base, the space is limited and machine tools cannot be used for drilling. Therefore, magnetic drills are generally used for drilling in limited working space. However, magnetic drills are currently not equipped with drill bits that can drill flat-bottom holes. Therefore, how to solve the above problems has become a technical problem to be solved. Summary of the invention

In addition, these processes may include more or fewer operations, and these operations or steps may be executed in sequence or in parallel, and these operations or steps may be combined.

[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0034] In a first aspect, an embodiment of the present application provides a drill bit for a magnetic drill based on a U drill.

[0035] In one embodiment, referring to Figure 1 , Figure 1 This is a schematic structural diagram of the first embodiment of a magnetic drill bit for a U-drill according to the present application. Figure 1 As shown, the drill bit for a magnetic drill based on a U drill includes a drill body 1 , a U drill bit 2 and a drill shank 3 .

[0036] Among them, the U drill bit 2 is arranged on one side of the drill bit body 1; the drill shank 3 is arranged on the other side of the drill bit body 1, and the length of the drill shank 3 is shortened to a size suitable for the magnetic drill chuck 4 based on the drill shank length of the U drill, and the drill shank 3 is also provided with a circumferential thickening layer, so that the diameter of the drill shank 3 is increased to a size suitable for the magnetic drill chuck 4 based on the drill shank diameter of the U drill.

[0037] It is worth mentioning that the U drill is also called shallow hole drill, violent drill, water injection drill, etc. It has a water outlet at the bottom. Compared with ordinary drill bits, it is more efficient and can process deep holes 5 times the diameter under high tool stability. It is usually used for machine tools to process deep flat-bottom holes, so its model size is not compatible with magnetic drill chucks.

[0038] For example, the single-edge U drill of model TCAP-08R-2.25D has a shank diameter of 10mm and a length of 38mm, while the diameter of the magnetic drill chuck is 19-20mm, and the suitable depth for assembly is 22-25mm. The preferred size is 19.1mm in diameter and 23mm in depth. It can be seen that the sizes of the U drill and the magnetic drill chuck are not compatible, and the two cannot be installed.

[0039] For this reason, the drill bit for the magnetic drill in this application is based on the U drill, which is modified to adapt the U drill and the magnetic drill chuck. Since the relevant dimensions of the magnetic drill chuck are known in advance, the U drill with the closest model can be selected first, so that the processing time will be minimized. Generally speaking, it is more convenient to choose a U drill with a small diameter for welding and thickening than to choose a U drill with a large diameter for cutting and thinning, so a U drill with a smaller diameter than the magnetic drill chuck will be selected for modification. Since the shank of the U drill is too long, a part of it needs to be cut off first, and for the remaining part, welding is used, and welding is performed along the circumference of the shank to increase the shank diameter until it is adapted to the magnetic drill chuck.

[0040] In one embodiment, the drill shank 3 is further provided with a positioning plane 31 for mounting and positioning with the magnetic drill chuck. The magnetic drill chuck 4 includes a receiving portion, and the receiving portion is provided with a through hole 41, and the receiving portion is used to receive the drill shank 3, so that the positioning plane 31 can be tightened by passing a bolt through the through hole 41, thereby completing the fixation of the two.

[0041] In addition, a detachable blade 21 is provided on the U-drill bit 2, so that when the drill bit is worn, only part of the blade needs to be replaced, which is highly efficient.

[0042] When the two are assembled, on the one hand, they have the processing capabilities of a U drill, and on the other hand, after being installed in the magnetic drill chuck, they can be processed in the limited space on board, thus solving the problem that flat-bottom holes cannot be processed in the limited space on board.

[0043] In summary, the drill head of the magnetic drill based on the U drill in the present application adopts a U drill bit, so it can be used to drill deep flat-bottomed holes. In order to solve the adaptation problem, the length of the drill shank is shortened to a size that is compatible with the magnetic drill chuck based on the length of the drill shank of the U drill, and the drill shank is also provided with a circumferential thickening layer, so that the diameter of the drill shank is increased to a size that is compatible with the magnetic drill chuck based on the diameter of the drill shank of the U drill. In this way, the drill shank can be installed on the magnetic drill chuck for drilling, without the need to use a machine tool for processing, which solves the problem that flat-bottomed holes cannot be processed in the limited space on the ship.

[0044] In a second aspect, an embodiment of the present application provides a magnetic drill based on a U drill.

[0045] In one embodiment, referring to Figure 1 and Figure 2 , Figure 1 and Figure 2 This is a structural diagram of the first embodiment of the magnetic drill based on the U drill of this application. Figure 1 and Figure 2 As shown, the U-drill-based magnetic drill includes a magnetic drill bit and a magnetic drill chuck 4 , and the magnetic drill bit includes a drill body 1 , a U-drill bit 2 and a drill shank 3 .

[0046] Among them, the U drill bit 2 is arranged on one side of the drill bit body 1; the drill shank 3 is arranged on the other side of the drill bit body 1, and the length of the drill shank 3 is shortened to a size suitable for the magnetic drill chuck 4 based on the drill shank length of the U drill, and the drill shank 3 is also provided with a circumferential thickening layer, so that the diameter of the drill shank 3 is increased to a size suitable for the magnetic drill chuck 4 based on the drill shank diameter of the U drill.

[0047] Furthermore, in one embodiment, the drill handle 3 is also provided with a positioning plane 31 for mounting and positioning with a magnetic drill chuck;

[0048] The magnetic drill chuck 4 includes a receiving portion, and a through hole 41 is provided on the receiving portion. The receiving portion is used to receive the drill shank 3 and tighten the positioning plane 31 by a bolt passing through the through hole 41 .

[0049] Furthermore, in one embodiment, the thickened layer is a welding layer formed around the drill shank of the U drill.

[0050] Furthermore, in one embodiment, the U-drill bit 2 is provided with a detachable blade 21 .

[0051] Furthermore, in one embodiment, the length of the drill shank 3 is 22-25 mm.

[0052] Furthermore, in one embodiment, the diameter of the drill shank 3 is 19-20 mm.

[0053] In summary, the magnetic drill based on the U drill in the present application uses a U drill bit in its drill head, so it can be used to drill deep flat-bottomed holes. In order to solve the adaptation problem, the length of the drill shank is shortened to a size that is compatible with the magnetic drill chuck based on the length of the drill shank of the U drill, and the drill shank is also provided with a circumferential thickening layer, so that the diameter of the drill shank is increased to a size that is compatible with the magnetic drill chuck based on the diameter of the drill shank of the U drill. In this way, the drill shank can be installed on the magnetic drill chuck for drilling, without the need to use a machine tool for processing, which solves the problem that flat-bottomed holes cannot be processed in the limited space on the ship.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
