Description

[0002] In modern manufacturing, drilling is one of the indispensable processes in the processing of various materials such as metals, plastics, and composite materials.

[0003] Comparative document 1 discloses a drilling device with application number: 202310768379.X. When different types of apertures need to be processed on parts, the drill bit of the corresponding aperture model can be automatically installed on the drilling motor without manual installation. It is convenient and fast, saving manual labor intensity. When installing the drill bit, it can automatically align and firmly fix the drill bit so that it will not fall off during work. After the drill bit is installed, the gear disk can be stored so that it does not interfere with the drilling work of the drill bit.

[0004] In the above-mentioned actual use process, it is difficult to ensure that the drill bit axis is completely coaxial with the drive shaft by only aligning and fixing the drill bit at a single point, which can easily lead to deviation during the drilling process and affect the processing accuracy. Especially when processing composite materials with high hardness or strong heterogeneity, the drill bit is subjected to uneven force, which can easily cause concentrated wear, chipping and even breakage, reducing processing efficiency and increasing the frequency of tool replacement.

[0032] In the description of this application, the term "for example" is used to mean "used as an example, illustration or explanation". Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is given to enable any person skilled in the art to implement and use the present invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art will recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0033] Example 1

[0034] See also Figures 1 to 4, an embodiment of the present invention provides a drilling device for processing various types of materials, including a drilling part 10, a maintenance-free drill bit 20 and a connecting assembly 30; the maintenance-free drill bit 20 is connected to the drilling part 10 through the connecting assembly 30; the connecting assembly 30 includes a mounting block 31 mounted on the maintenance-free drill bit 20, the mounting block 31 is conical; a plurality of limiting strips 32 are mounted on the conical surface of the mounting block 31; a transmission block 33 is mounted on the rotating end of the drilling part 10; a mounting groove 34 is defined in the transmission block 33, and the mounting groove 34 allows the mounting block 31 to enter the transmission block 33; a plurality of limiting grooves 35 are defined in the transmission block 33, and a plurality of the limiting grooves 35 are located in the mounting groove 34, and the plurality of limiting grooves 35 cooperate with the corresponding limiting strips 32 to limit the mounting block 31 entering the mounting groove 34.

[0035] The transmission block 33 defines a plurality of guide slots 36 , which are in communication with the corresponding limiting slots 35 for guiding the corresponding limiting bars 32 into the limiting slots 35 .

[0036] It should be noted that the position of the limit bar 32 can be corrected by using the guide groove 36, so that when the free-grinding drill bit 20 is installed, the position of the free-grinding drill bit 20 does not need to be adjusted, thereby improving the installation speed of the free-grinding drill bit 20.

[0037] A positioning member 37 is installed on the transmission block 33 , and the positioning member 37 is used to position the installation block 31 entering the installation groove 34 .

[0038] It should be noted that the positioning member 37 adopts the existing technology, and can limit the mounting block 31 after the mounting block 31 enters the mounting groove 34, so that the mounting block 31 will not fall out of the mounting groove 34.

[0039] Specific implementation:

[0040] When the maintenance-free drill bit 20 needs to be installed, the maintenance-free drill bit 20 is moved upward through the components on the drilling member 10. The upward movement of the maintenance-free drill bit 20 will drive the mounting block 31 and the limit bar 32 to move upward. After the limit bar 32 moves up and enters the mounting groove 34, if the limit groove 35 and the limit bar 32 are not in the same straight line, the guide groove 36 will guide the limit bar 32 to make the limit bar 32 and the mounting block 31 rotate, and then the limit bar 32 can enter the limit groove 35 to complete the installation of the maintenance-free drill bit 20.

[0041] The limiting strip 32 and the limiting groove 35 can ensure that the axis of the maintenance-free drill bit 20 is coaxial with the transmission block 33, reducing drilling deviation and improving drilling accuracy. At the same time, multi-point engagement can disperse stress, reduce local wear, and extend the life of the drill bit. Finally, the conical structure of the mounting block 31 and the guide groove 36 are used to automatically correct the limiting strip 32, thereby improving the installation speed of the maintenance-free drill bit 20.

[0042] Example 2

[0043] Since some debris will splash onto the mounting block 31 when the free-grinding drill bit 20 is replaced during the drilling process and after drilling, affecting the fit between the mounting block 31 and the mounting groove 34, thereby affecting the drilling accuracy, improvements are made;

[0044] See also Figure 5 An embodiment of the present invention provides a drilling device for processing multiple types of materials. An extrusion airbag 40 is installed on the top of the mounting block 31. A plurality of air outlet holes 41 are opened on the extrusion airbag 40. The gas discharged from the plurality of air outlet holes 41 is used to clean foreign matter on the mounting block 31. A composite metal rubber layer is provided on the extrusion airbag 40, and a plurality of friction particles are provided on the surface of the composite metal rubber layer.

[0045] It should be noted that after the extrusion airbag 40 is squeezed, the extrusion airbag 40 contracts to form a damping effect, while enhancing the absorption of low-frequency vibrations through particle friction, thereby improving the overall attenuation rate.

[0046] A combination valve is installed on each of the plurality of air outlet holes 41 , and the combination valves are opened when the air pressure in the extrusion airbag 40 reaches a preset value.

[0047] It should be noted that the combination valve is composed of an exhaust valve and a one-way valve. The exhaust valve is responsible for opening the exhaust when the pressure reaches the standard, and the one-way valve independently controls the air intake channel and allows air to enter only when the airbag is restored.

[0048] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0049] The extrusion airbag 40 is squeezed by the grinding-free drill bit 20 in cooperation with the transmission block 33, so that the air pressure in the extrusion airbag 40 increases. After the air pressure reaches the preset value, the gas in the extrusion airbag 40 is discharged, and the jet air flow cleans the foreign matter between the mounting block 31 and the mounting groove 34, thereby improving the fit between the mounting block 31 and the mounting groove 34 and avoiding the presence of foreign matter between the two, which causes the deviation of the grinding-free drill bit 20 and affects the drilling accuracy.

[0050] Example 3

[0051] Since the instantaneous torque impact when the drill motor starts will cause the axial jitter of the free-grinding drill bit 20 before it contacts the workpiece, it may cause the initial hole position to shift. At the same time, during the drilling process, due to factors such as uneven material resistance and poor chip removal, radial vibration will occur, resulting in an increase in the hole diameter. Therefore, improvements are made;

[0052] See also Figure 5 and Figure 6 An embodiment of the present invention provides a drilling device for processing multiple types of materials. A first buffer airbag 50 is installed on the top of the mounting block 31. A second buffer airbag 51 is sleeved on the surface of the first buffer airbag 50. The second buffer airbag 51 is located on one side of the extrusion airbag 40.

[0053] It should be noted that the Newtonian fluid airbag in the first cushioning airbag 50 is subjected to millisecond impact (shear rate> 1000s -1 ) Rapid hardening, rigid absorption of more than 80% of impact energy, the second buffer airbag 51, also known as the liquid-coupled airbag, converts medium and high frequency vibration energy into heat energy dissipation through silicone oil viscous resistance and air pressure adjustment, with an attenuation rate of ≥60%.

[0054] The second cushioning airbag 51 is filled with silicone oil and compressed gas, and the first cushioning airbag 50 is filled with shear-thickening non-Newtonian fluid.

[0055] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0056] The non-Newtonian fluid in the first buffer airbag 50 is used to cope with transient impacts, so that at the moment the drill bit rotates, the non-Newtonian fluid is hardened to absorb the impact, and during the rotation of the drill bit, the vibration energy is dissipated by viscous damping, thereby achieving the coordination of material properties (non-Newtonian fluid) and fluid mechanics (gas-liquid coupling), realizing impact-vibration frequency division control, eliminating drill edge chipping, hole mouth burrs and hole wall roughness, and improving drilling quality and the service life of the drill bit.

[0057] Example 4

[0058] See also Figures 4 to 6 The embodiment of the present invention provides a grinding-free drill bit for drilling equipment for processing various types of materials. The installation positions of the first buffer airbag 50, the second buffer airbag 51 and the extrusion airbag 40 (the airbags are replaceable) can be divided into two types. One is to be installed on the mounting block 31. During subsequent use, it is convenient to replace the first buffer airbag 50, the second buffer airbag 51 and the extrusion airbag 40. At the same time, multiple mounting blocks 31 correspond to multiple airbags, which can avoid the continuous use of a single airbag and affect the service life. The other is to be installed in the mounting groove 34. Only one set of airbags is required, which can reduce the cost of use, but the service life will be affected to a certain extent.

[0059] Example 5

[0060] See also Figure 7-Figure 9 An embodiment of the present invention provides a grinding-free drill bit for drilling equipment for processing various types of materials. A regulating mechanism 6 is installed on the transmission block 33, and the regulating mechanism 6 includes a liquid storage barrel 61 relatively installed on the transmission block 33; a separation tube 62 is installed and connected to the liquid storage barrel 61; a separation plate 63 is installed inside the separation tube 62, and the separation plate 63 divides the separation tube 62 into two separate areas; a pressure pump 64 and an extraction pump 65 are respectively installed on the separation tube 62 and on both sides of the separation plate 63, and a sealing ring 66 is installed on the mounting block 31.

[0061] It should be noted that the liquid storage barrel 61 is filled with positioning liquid, which is a combination of debris (metal chips, which need to be screened and the screened particles are small, with a particle size of (50-150μm)) and liquid (such as grease, water-based liquid), which can be transported into the installation groove 34, and then pressurized to compact the filler, and the limit strip 32 is locked by friction and static pressure.

[0062] It should be noted that, in this embodiment, the gap of the limiting groove 35 is greater than the width of the limiting strip 32 , so that the limiting strip 32 can slide in the limiting groove 35 , thereby allowing the drill body 202 to rotate at a certain angle.

[0063] It should be noted that valve bodies are installed in the areas on both sides of the partition plate 63 corresponding to the partition tube 62. The two valve bodies can only allow liquid to enter and exit according to the needs of use on both sides of the partition plate 63, and the bottom end of the partition tube 62 is connected to the bottom of the transmission block 33 and is located in the installation groove 34 to facilitate the extraction of liquid.

[0064] It should be noted that a sealing gasket is installed in the sealing ring 66. After the mounting block 31 enters the mounting groove 34, the sealing ring 66 is sleeved on the bottom of the transmission block 33 to achieve sealing between the two, and the positioning of the sealing ring 66 is replaced with magnetic attraction or other positioning methods.

[0065] In the initial state, the amount of positioning liquid in the installation groove 34 is insufficient or is in a low-pressure state. At this time, the drill body 202 can rotate at a certain angle under the action of the limit bar 32 and the limit groove 35. When the drill body 202 needs to be stabilized, the positioning liquid in the liquid storage barrel 61 is extracted by the pressure pump 64 in conjunction with the separation tube 62 and transported to the installation groove 34, so that the pressure of the positioning liquid in the installation groove 34 is increased, and the limit bar 32 is positioned by the high-pressure positioning liquid, so that the drill body 202 will not rotate in the transmission block 33.

[0066] If hard spots or foreign objects are encountered inside the material during drilling, the positioning liquid in the installation groove 34 can be extracted to slightly change the angle of the drill shell, and the angle floating can be used to cushion the impact force to avoid tool breakage or workpiece cracking; after penetration, the drill bit is stabilized by pressurizing the positioning liquid to ensure that the subsequent hole wall is smooth and vertical. This "rigid-flexible transient" capability is particularly suitable for composite laminates, special-shaped surfaces or manual intervention scenarios. It can not only cope with unpredictable resistance mutations, but also ensure the processing accuracy of key links, while reducing the frequency of shutdowns and replacements, increasing efficiency by more than 30%, and greatly reducing tool loss and scrap rate caused by the limitations of a single mode.

[0067] Example 6

[0068] In the CNC machining industry, traditional roughing drills use different types of drills to process different materials, and the drills wear quickly, resulting in a short tool life, which invisibly increases tool change and grinding time and increases labor costs. Further improvements are needed;

[0069] See also Figure 10 An embodiment of the present invention provides a maintenance-free drill bit for drilling equipment used for processing multiple types of materials. The maintenance-free drill bit 20 includes a shank 201, a drill body 202, a main cutting edge 203, a secondary cutting edge 204, a formed cutting groove 205, and a chip groove 206. The shank 201 and the drill body 202 are fixedly connected; the main cutting edge 203 and the secondary cutting edge 204 are both arranged on the drill body 202, and the secondary cutting edge 204 is axially arranged on both sides of the main cutting edge 203; the formed cutting groove 205 is opened on the end of the drill body 202 away from the shank 201; and the chip groove 206 is arranged on both sides of the secondary cutting edge 204.

[0070] It should be noted that the drill body 202 adopts a whole carbide sintering process and is combined with surface nano-coating technology, so that the integrity of the cutting edge can be maintained under high temperature and high pressure working conditions.

[0071] The core design of this maintenance-free drill bit is based on optimized geometric structure and dynamic cutting balance principle. The main cutting edge serves as the main cutting unit. The 140-degree symmetrically distributed tip design achieves balanced distribution of axial force, significantly reducing the risk of overload. The secondary cutting edges 204 are axially distributed on both sides of the main edge. Its parabolic clearance angle is modeled through mathematical surfaces to form a progressive cutting trajectory, effectively decomposing radial cutting resistance. The formed cutting groove 205 adopts a bionic streamline design to generate negative pressure vortex during the rotation of the drill bit, accelerating the spiral upward movement of the chips; the chip groove 206 realizes the continuous fracture and directional discharge of metal chips.

[0072] It should be noted that the chip groove 206 can increase the speed of chip removal. The rapid discharge of chips can also bring out the processing heat by the chips, thereby reducing the cutting heat of the tool and achieving the effect of protecting the tool. Through the composite cutting mechanism of the main and secondary edges, it can simultaneously meet the processing requirements of 9 types of materials such as aluminum alloy, titanium alloy, and hardened steel.

[0073] The cutting edge of the drill body 202 is arranged at a 140-degree angle and is symmetrically distributed.

[0074] It should be noted that the 140-degree setting of the tool tip in conjunction with the formed cutting slot 205 at the center of the tool tip has the advantages of smaller cutting resistance, faster chip removal, and better wear resistance than traditional tooth slots.

[0075] The parabolic relief angle on the secondary cutting edge 204 is ten degrees.

[0076] It should be noted that the parabolic clearance angle can reduce the processing friction coefficient, achieve wear resistance, and increase processing life.

[0077] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0078] The drill bit adopts a symmetrical cutting edge design and a parabolic relief angle structure, which significantly improves dynamic stability by suppressing resonance modes and reconstructing the cutting stress field. The symmetrical configuration achieves balanced heat flow distribution and effectively reduces the cutting temperature gradient. The parabolic blade shape converts cutting vibration into a stable processing state, while optimizing the stress release path. The fluid mechanics-optimized spiral groove and the variable diameter chip removal channel work together to greatly improve chip removal efficiency and control chip morphology, so as to maintain stable cutting performance when continuously processing different materials, taking into account both surface quality and ultra-long service life, and realizing the ability to operate continuously without repair and grinding.

[0079] It should be noted that, in the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
