Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing tools, in particular to a drilling and milling cutter integrating a milling cutter and a drill bit and a production process thereof. Background Art

[0002] A drill-milling cutter is a tool that combines the functions of a drill and a milling cutter. It combines the drilling ability of a drill and the milling ability of a milling cutter. It can be used for various operations such as grooving, drilling positioning holes, chamfering, etc. It can complete operations such as drilling and milling planes on the workpiece in one process, improving processing efficiency and reducing processing errors caused by multiple clamping in traditional processing methods.

[0003] In the prior art, during the actual operation of a drilling and milling cutter, a large amount of lubricating fluid needs to be sprayed at multiple angles at the working position to cool the cutter head and provide lubrication for the processing position, thereby reducing tool wear and improving tool life and the quality of the processing position. However, since a drilling and milling cutter has two functional areas, the following deficiencies exist during the actual processing: first, in order for the cutting fluid to cover the entire working area, the spraying range and dosage need to be increased. When the milling cutter and the drill bit are used for a single function, the cutting fluid will be wasted. When the milling cutter is working, the cutting fluid at the drill bit position does not play a role; second, there may be interference between the milling cutter and the drill bit functional areas. When the milling cutter is operating, the drill bit functional area is located at the bottom of the milling cutter and may contact the workpiece, resulting in a restricted processing position and reduced processing effect. In response to the deficiencies in the prior art, the present invention provides a drilling and milling cutter and a production process that integrates a milling cutter and a drill bit to solve the above problems. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a drilling and milling cutter and a production process that integrates a milling cutter and a drill bit. The lubricating liquid delivery path can be automatically adjusted according to the state of the drill bit body. When the milling cutter or the drill bit works alone, the lubricating liquid only provides lubrication to the working part, reducing waste; when the functions of both are used at the same time, the pressure is increased to lubricate synchronously, reducing lubricating liquid consumption. The position of the drill bit body is adjusted by the adjustment unit.

[0019] When the drill body is in the extended state, the lower guide hole and the inner part of the milling cutter mounting seat are released from the fitting state, the position of the lower guide hole is lower than the position of the side guide groove, and the lubricating fluid is sprayed out from the lower guide hole and automatically lubricates the drill body.

[0020] Preferably, when the functions of the milling cutter head and the drill body are used at the same time, the pressure of the lubricating liquid is increased so that the lubricating liquid fills the lubricating liquid delivery cavity formed between the embedded groove, the adjustment column and the support seat, and the lubricating liquid is sprayed out from the side guide groove and the lower guide hole respectively, thereby synchronously realizing the lubrication operation of the milling cutter head and the drill body.

[0021] Preferably, the lubrication guide unit also includes a convex ring arranged inside the milling cutter mounting seat and an alignment hole opened inside the convex ring. An inner guide hole is opened inside the inner guide groove, and the inner guide hole is connected to the embedded groove.

[0029] A second aspect of the present invention provides a production process for a milling cutter that integrates a milling cutter and a drill bit. The production process comprises the following steps: Step S1, selecting high-strength alloy steel material for making a tool handle, a connecting seat, a milling cutter mounting seat, and a support seat, and selecting cemented carbide material for making a milling cutter head and a drill bit body;

[0030] Step S2, forming the raw materials into the blank shapes of the components through a casting process;

[0031] Step S3, machining the blank to accurately process the outer dimensions, hole positions, and slot positions of each component;

[0032] Step S4, performing a heat treatment process on the processed parts;

[0038] The present invention discloses a milling cutter and a drill bit integrated with a milling cutter and a production process, which have the following beneficial effects:

[0039] 1. This drill-milling cutter, which is a fusion of a milling cutter and a drill bit, can, first, automatically adjust the lubricant delivery path according to the state of the drill body. When the drill body is in the retracted state and the milling cutter head is used, the lubricant only lubricates the milling cutter head; when the drill body is in the extended state and works alone, the lubricant only lubricates the drill body; when the milling cutter head and the drill body are used at the same time, both are lubricated synchronously by increasing the pressure. This precise lubrication method greatly reduces the consumption of lubricant and improves resource utilization. Secondly, the setting of the adjustment unit allows the drill body to be flexibly adjusted between the extended and retracted states, facilitating quick switching between milling and drilling functions to meet different processing needs. When only the milling cutter head is used, the drill body is in the retracted state, avoiding contact with the workpiece, preventing interference with the functional area, improving the processing effect, and increasing the flexibility and efficiency of processing.

[0040] 2. This integrated milling cutter and drill bit drill milling cutter features a support seat that slides within the embedded slot, supporting and limiting the drill bit body. The threaded stud on the support seat is threadedly connected to the spiral seat on the drill bit body. This connection ensures the stability of the drill bit body installation and facilitates removal and replacement of the drill bit body, making it easy to replace drill bits of different models. The slot design ensures stable installation of the milling cutter head, which is laterally supported by the milling cutter mounting seat. The fixing hole and first locking bolt design facilitate assembly and disassembly of the milling cutter head, making it easy to maintain.

[0041] 3. This integrated milling cutter and drill bit features an arc-shaped dispersion groove on the cutter head, aligned with the side guide groove. When the lubricant is ejected from the side guide groove, it is guided and dispersed by the dispersion groove, allowing it to be distributed more widely and evenly adhered to the working range of the milling cutter head, thereby improving lubrication efficiency and tool life.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0057] The embodiments of the present application provide a drilling and milling cutter and a production process that integrates a milling cutter and a drill bit, thereby solving the problem in the prior art that when the milling cutter and the drill bit are used for a single function, the cutting fluid spreads throughout the entire working area, causing waste of cutting fluid, and the drill bit functional area may contact the workpiece during milling operation, resulting in a limited processing position and reduced processing effect.

[0058] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0059] Example 1:

[0060] The embodiment of the present invention discloses a milling cutter and a drill bit fusion drill cutter. Figure 1 To the attached Figure 12 As shown, it includes a tool handle 1, a connecting seat 2, a milling cutter mounting seat 3, a milling cutter head 4, a drill body 5, a support seat 6, an adjustment unit 7 and a lubrication guide unit 8;

[0061] The function of the tool holder 1 is to connect the output end of the equipment, serving as a bridge connecting the entire drilling and milling cutter and the equipment, transmitting the power output by the equipment to subsequent components, so that the drilling and milling cutter can operate normally.

[0062] The connecting seat 2 is arranged on the tool handle 1, and serves to connect the tool handle 1 with the milling cutter mounting seat 3 and the support adjustment unit 7, providing an installation basis and support structure for other components.

[0063] The milling cutter mounting base 3 is mounted on the connecting base 2 and includes an internal recess 31 for accommodating the drill bit 5. The milling cutter mounting base 3 also includes a retaining groove 33 for retaining the milling cutter head 4, ensuring stable and accurate installation. Furthermore, the milling cutter mounting base 3 includes a cutting guide 32 for chip removal. During the milling process, these guides effectively direct and discharge generated chips, preventing their accumulation from impacting machining quality and tool life.

[0064] The milling cutter head 4 is mounted on the milling cutter mounting base 3 and secured in place by a retaining slot 33 provided therein. A first locking bolt 34 is threadedly connected to the milling cutter mounting base 3, ensuring a secure installation of the milling cutter head 4. The milling cutter head 4 is provided with a dispersion channel 41 aligned with the side guide groove 83. As the lubricant flows out of the side guide groove 83, the dispersion channel 41 distributes the lubricant more evenly to all parts of the milling cutter head 4, improving lubrication. The milling cutter head 4 is designed for milling operations and is constructed from cemented carbide, ensuring its hardness and wear resistance, making it suitable for high-intensity milling operations.

[0065] The drill body 5 is positioned within the insert slot 31 and is provided with a screw seat 51. A drill guide hole 85 is defined within the screw seat 51. The drill guide hole 85 aligns with the lower guide hole 84 to ensure smooth delivery of lubricant to the corresponding position within the drill body 5. The drill body 5 is used for drilling and is also made of cemented carbide to meet the required hardness and strength.

[0066] The support base 6 is slidably connected within the recess 31 and serves to support and position the drill body 5. A threaded post 61 is provided on the support base 6, which is threadedly connected to the screw seat 51 on the drill body 5. This connection ensures the stability of the drill body 5 while facilitating its removal and replacement, making it easier to change models of drill bodies 5. Furthermore, the support base 6 is provided with a lower guide hole 84, through which lubricating fluid can be sprayed to lubricate the drill body 5.

[0067] An adjustment unit 7 is disposed between the connecting base 2 and the support base 6 and is used to adjust the position of the support base 6, thereby adjusting the extended and retracted positions of the drill body 5. The adjustment unit 7 comprises an adjustment post 71 fixedly connected to the support base 6 and a locking structure for retaining the adjustment post 71. A guide tube 711 is provided on the adjustment post 71, which is slidably connected to the interior of the main flow channel 81, ensuring smooth lubrication delivery.

[0068] The lubrication guide unit 8 is used to guide the lubricating liquid to the drilling and milling cutter as a whole, including a main guide groove 81 opened inside the tool handle 1, an inner guide groove 82 arranged inside the adjusting column 71 and connected to the main guide groove 81, a side guide groove 83 arranged inside the milling cutter mounting seat 3 and connected to the embedded groove 31, and a lower guide hole 84 arranged on the support seat 6.

[0069] In addition, the lubrication guide unit 8 also includes a convex ring 86 arranged inside the milling cutter mounting seat 3 and an alignment hole 861 opened inside the convex ring 86. An inner guide hole 821 is opened inside the inner guide groove 82, and the inner guide hole 821 is connected to the embedded groove 31.

[0070] When the drill body 5 is in the stored state, the milling cutter head 4 is used for operation. The lower guide hole 84 is sealed with the convex ring 86, and the alignment hole 861 is aligned with the inner guide hole 821. The lubricating fluid enters the side guide groove 83 from the alignment hole 861 and the inner guide hole 821. At this time, the lubricating fluid only lubricates the milling cutter head 4.

[0071] When the drill body 5 is in the extended state, the drill body 5 is used for work, the lower guide hole 84 is released from the inner state of the milling cutter mounting seat 3, the position of the lower guide hole 84 is lower than the position of the side guide groove 83, and the lubricating liquid is sprayed out from the lower guide hole 84 and automatically lubricates the drill body 5. At this time, the lubricating liquid only provides lubrication for the drill body 5.

[0072] When the drill body 5 is in the extended state and the functions of the milling cutter head 4 and the drill body 5 need to be used at the same time, the pressure of the lubricating liquid is increased so that the lubricating liquid fills the lubricating liquid delivery cavity formed between the embedded groove 31, the adjustment column 71 and the support seat 6, and the lubricating liquid is sprayed out from the side guide groove 83 and the lower guide hole 84 respectively, so that the lubrication operation of the milling cutter head 4 and the drill body 5 can be realized synchronously.

[0073] Therefore, the drill-milling cutter that integrates the milling cutter and the drill bit can automatically adjust the lubricating fluid delivery path according to the state of the drill bit body 5, accurately lubricate the milling cutter head 4 and the drill bit body 5 respectively, reduce the consumption of lubricating fluid, and improve the performance and life of the tool.

[0074] Example 2:

[0075] The embodiment of the present invention discloses a milling cutter and a drill bit fusion drill cutter. Figure 1 To the attached Figure 12 As shown, it includes a tool handle 1, a connecting seat 2, a milling cutter mounting seat 3, a milling cutter head 4, a drill body 5, a support seat 6, an adjustment unit 7 and a lubrication guide unit 8;

[0076] The tool handle 1 is connected to the output terminal of the device;

[0077] The connecting seat 2 is arranged on the handle 1;

[0078] The milling cutter mounting base 3 is arranged on the connecting base 2 and has an embedding groove 31 formed therein;

[0079] The milling cutter head 4 is mounted on the milling cutter mounting seat 3;

[0080] The drill body 5 is disposed in the embedding groove 31;

[0081] The support seat 6 is slidably connected to the inside of the embedding groove 31 and is used to support and limit the drill body 5;

[0082] The adjustment unit 7 is provided between the connecting base 2 and the supporting base 6 and is used to adjust the position of the supporting base 6. The adjustment unit 7 includes an adjustment column 71 fixedly connected to the supporting base 6 and a locking structure for limiting the adjustment column 71;

[0083] The lubricating guide unit 8 is used to guide the lubricating liquid to the drill and milling cutter as a whole. The lubricating guide unit 8 includes a main guide groove 81, an inner guide groove 82, a side guide groove 83 and a lower guide hole 84;

[0084] The main flow channel 81 is provided inside the handle 1;

[0085] The inner guide groove 82 is provided inside the regulating column 71 and communicates with the main flow groove 81;

[0086] The side guide groove 83 is provided inside the milling cutter mounting seat 3 and communicates with the embedding groove 31;

[0087] The lower guide hole 84 is disposed on the support base 6 .

[0088] The locking structure includes:

[0089] The adjusting block 72 is arranged on the adjusting column 71, and the connecting seat 2 is provided with a sliding groove 21 corresponding to the adjusting block 72;

[0090] The limiting rail 73 is provided on the connecting seat 2 , and a second locking bolt 731 is threadedly connected between the limiting rail 73 and the adjusting block 72 .

[0091] In the locking structure, by adjusting the position of the adjusting block 72 in the slide groove 21, the position of the adjusting column 71 can be changed, and then the position of the support seat 6 can be changed to adjust the state of the drill body 5. After adjustment, the adjusting block 72 is locked by tightening the second locking bolt 731 to fix the position of the adjusting block 72, the adjusting column 71 and the support seat 6, thereby locking the position of the drill body 5.

[0092] The milling cutter mounting base 3 is provided with a slot 33 for limiting the position of the milling cutter head 4. A first locking bolt 34 is threadedly connected between the milling cutter head 4 and the milling cutter mounting base 3. The milling cutter head 4 is provided with a fixing hole 42 corresponding to the first locking bolt 34. The design of the slot 33 ensures stable installation of the milling cutter head 4, and the milling cutter head 4 is laterally supported by the milling cutter mounting base 3. The design of the fixing hole 42 and the first locking bolt 34 makes it easy to disassemble and assemble the milling cutter head 4 and easy to maintain.

[0093] The milling cutter head 4 is provided with a dispersion guide groove 41 aligned with the side guide groove 83. The dispersion guide groove 41 is set to an arc shape. When the lubricating liquid is sprayed out from the side guide groove 83, it is guided and dispersed by the dispersion guide groove 41, so that the lubricating liquid is distributed over a wide range and evenly adheres to the working range of the milling cutter head 4, thereby improving the lubrication effect and tool life.

[0094] A conduit 711 is provided on the adjusting column 71, and the conduit 711 is slidably connected to the inside of the main flow groove 81. When the adjusting column 71 adjusts its position, the conduit 711 is located inside the main flow groove 81, always maintaining the connection between the inner guide groove 82 and the main flow groove 81, ensuring stable lubricating liquid delivery.

[0095] A second aspect of the present invention provides a production process for a milling cutter that integrates a milling cutter and a drill bit. The production process comprises the following steps: Step S1: selecting high-strength alloy steel material to manufacture a tool handle 1, a connecting seat 2, a milling cutter mounting seat 3, and a support seat 6; the tool handle 1, the connecting seat 2, and the milling cutter mounting seat 3 are manufactured by an integrated molding process; the support seat 6 and the adjustment column 71 are manufactured by an integrated molding process; and cemented carbide material is selected to manufacture the milling cutter head 4 and the drill bit body 5. The cemented carbide tool can maintain cutting performance for a long time, effectively improving processing efficiency and quality;

[0096] Step S2, using a casting process to make the raw materials into the blank shape of each component. The casting process is based on the design requirements. The metal material is melted and poured into a pre-made mold. After cooling and solidification, the blank of the required shape is obtained;

[0097] Step S3, machining the blank to accurately process the outer dimensions, hole positions, and slot positions of each component;

[0098] Step S4: heat treating the processed parts to improve their hardness, strength, toughness, and wear resistance. For high-strength alloy steel parts, a quenching and tempering process is used. For cemented carbide parts, the heat treatment mainly involves sintering the powdered cemented carbide material at high temperature into a dense solid to further improve its hardness and wear resistance.

[0099] Step S5, performing surface treatment and sandblasting passivation treatment on each component. The surface treatment of each component includes chrome plating and nitriding operations. The chrome plating operation forms a chromium layer with high hardness and good wear resistance on the surface of the component, thereby improving the corrosion resistance and aesthetics of the component and effectively preventing the components from rusting and corrosion. The nitriding treatment is to place the component in a nitrogen-containing atmosphere and heat it, so that nitrogen atoms penetrate into the surface of the component to form a nitride layer with high hardness, good wear resistance and fatigue resistance, thereby further improving the surface performance of the component. The sandblasting treatment can remove impurities such as oxide scale and oil stains on the surface of the component, making the surface rougher and increasing the adhesion of subsequent coatings or plating.

[0100] In step S6, the components that have undergone heat treatment and surface treatment are precisely assembled. Before assembly, the components need to be thoroughly cleaned to remove dust, oil and other impurities on the surface to ensure the matching accuracy and sealing between the components.

[0101] Step S7: During assembly, precisely arrange the various components of the lubricating guide unit 8. Ensure that the connections between the guide grooves and guide holes are smooth and free of blockage and leakage. Test the lubricating guide unit 8 by injecting a small amount of lubricating fluid into the unit. Check the flow of the lubricating fluid and make adjustments if any abnormalities are detected.

[0102] Step S8: The assembled drill and milling cutters are subjected to various performance tests, including dimensional accuracy, hardness, wear resistance, and lubrication performance tests. Products that fail these tests are analyzed in detail to identify the problem, and appropriate measures are taken to rework or scrap them.

[0103] Step S9: After performance testing and commissioning are complete and all indicators are qualified, the drill and milling cutters are packaged and shipped. The packaging material must be moisture-proof, rust-proof, and shock-resistant to protect the drill and milling cutters from damage during transportation and storage. The packaging is labeled with the product name, specifications, model, production date, and other information for easy identification and use. Only drill and milling cutters that have passed rigorous inspection are released for sale, providing users with high-quality processing tools.
