Description

Technical Field

[0001] The present invention relates to the technical field of machining tools, and specifically to a drill-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 integrates the functions of a drill bit and a milling cutter. It combines the drilling ability of the drill bit and the milling ability of the milling cutter, and can be used for various operations such as grooving, drilling positioning holes, and chamfering. It can complete operations such as drilling and milling the plane of the workpiece in one process, improving the processing efficiency and reducing the processing errors caused by multiple clampings in traditional processing methods.

[0003] In the prior art, usually during the actual operation of a drill-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, reduce tool wear, and improve the tool life and the quality of the processing position. However, due to the existence of two functional areas in the drill-milling cutter, there are the following deficiencies in the actual processing process. First, in order for the cutting fluid to cover the entire working area, it is necessary to increase the spraying range and dosage. When using the single functions of the milling cutter and the drill bit, it will cause waste of the cutting fluid. 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 functional areas of the milling cutter and the drill bit. 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 limited processing position and reduced processing effect. In view of the deficiencies of the prior art, the present invention provides a drill-milling cutter integrating a milling cutter and a drill bit and a production process thereof to solve the above problems. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a drill-milling cutter integrating a milling cutter and a drill bit and a production process thereof, which can automatically adjust the lubricating fluid delivery path according to the state of the drill bit body. When the milling cutter or the drill bit works alone, the lubricating fluid only provides lubrication for the working part, reducing waste; when using both functions simultaneously, lubrication is synchronized only by increasing the pressure, reducing the consumption of the lubricating fluid. The position of the drill bit body is adjusted by the adjusting unit. When only using the milling cutter head, the drill bit body is retracted to avoid contact with the workpiece and prevent interference between functional areas, improving the processing effect.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A drill-milling cutter integrating a milling cutter and a drill bit includes a tool shank, a connecting seat, a milling cutter mounting seat, a milling cutter head, a drill bit body, a support seat, an adjusting unit, and a lubricating and guiding unit;

[0038] The present invention discloses a drill-milling cutter integrating a milling cutter and a drill bit and its production process, and the beneficial effects thereof are as follows:

[0039] 1. For the drill-milling cutter integrating the milling cutter and the drill bit, firstly, this drill-milling cutter can automatically adjust the delivery path of the lubricating fluid according to the state of the drill bit body. When the drill bit body is in the retracted state and the milling cutter head is used for work, the lubricating fluid only provides lubrication for the milling cutter head; when the drill bit body is in the extended state and works alone, the lubricating fluid only provides lubrication for the drill bit body; when the functions of both the milling cutter head and the drill bit body are used simultaneously, both are lubricated synchronously by increasing the pressure. This precise lubrication method greatly reduces the consumption of the lubricating fluid and improves the resource utilization rate. Secondly, the setting of the adjustment unit enables the extended and retracted states of the drill bit body to be flexibly adjusted, facilitating rapid switching between the milling and drilling functions and meeting different processing requirements. When only the milling cutter head is used for work, the drill bit body is in the retracted state, avoiding contact with the workpiece, preventing interference in the functional area, and improving the processing effect, flexibility, and efficiency of processing.

[0040] 2. For the drill-milling cutter integrating the milling cutter and the drill bit, the support seat is slidably connected inside the embedded groove and is used to support and limit the drill bit body. The threaded post on the support seat is threadedly connected to the spiral seat on the drill bit body. This connection method can not only ensure the stability of the installation of the drill bit body but also facilitate the disassembly and replacement of the drill bit body, making it convenient to replace drill bit bodies of different models. Through the design of the card slot, the installation of the milling cutter head is stable and is laterally supported by the milling cutter mounting seat; through the design of the fixing hole and the first locking bolt, the disassembly and assembly of the milling cutter head are convenient and easy to maintain.

[0041] 3. For the drill-milling cutter integrating the milling cutter and the drill bit, the milling cutter head is provided with a dispersion guide groove aligned with the position of the side guide groove, and the dispersion guide groove is set to be arc-shaped. When the lubricating fluid sprays out from the side guide groove, through the guiding and dispersion of the dispersion guide groove, the distribution range of the lubricating fluid can be made wider, and it can be evenly attached to the working range of the milling cutter head, thereby improving the lubrication effect and the tool life.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0057] By providing a drill-milling cutter integrating a milling cutter and a drill bit and a production process in the embodiments of the present application, the problems in the prior art are solved. When the drill-milling cutter in the prior art is used for the single functions of the milling cutter and the drill bit, the cutting fluid fills the entire working area, resulting in waste of the cutting fluid. When the milling cutter is operating, the drill bit functional area may contact the workpiece, leading to limited machining positions and reduced machining effects.

[0058] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0059] Embodiment 1:

[0060] An embodiment of the present invention discloses a drill-milling cutter integrating a milling cutter and a drill bit. As shown in FIGS. Figure 1 to FIGS. Figure 12 it includes a tool shank 1, a connecting seat 2, a milling cutter mounting seat 3, a milling cutter head 4, a drill bit body 5, a support seat 6, an adjusting unit 7, and a lubricating and guiding unit 8.

[0061] The function of the tool shank 1 is to connect to the output end of the device. As the bridge for connecting the entire drill-milling cutter to the device, it transmits the power output by the device to the subsequent components, enabling the drill-milling cutter to operate normally.

[0062] The connecting seat 2 is arranged on the tool shank 1, serving to connect the tool shank 1 to the milling cutter mounting seat 3 and support the adjusting unit 7, providing an installation foundation and a support structure for other components.

[0063] The milling cutter mounting seat 3 is arranged on the connecting seat 2. An embedding groove 31 is formed inside it for accommodating the drill bit body 5. At the same time, a clamping groove 33 for limiting the milling cutter head 4 is also provided on the milling cutter mounting seat 3 to ensure the stability and accuracy of the installation of the milling cutter head 4. In addition, a cutting guide groove 32 for guiding the chips is also formed on the milling cutter mounting seat 3. During the milling process, the cutting guide groove 32 can effectively guide the generated chips out, avoiding chip accumulation from affecting the machining quality and tool life.

[0064] The milling cutter head 4 is installed on the milling cutter mounting seat 3, limited by the clamping groove 33 opened on the milling cutter mounting seat 3, and threadedly connected to the milling cutter mounting seat 3 using the first locking bolt 34 to ensure the firm installation of the milling cutter head 4. The milling cutter head 4 is provided with a dispersion guide groove 41 aligned with the position of the side guide groove 83. When the lubricating fluid flows out from the side guide groove 83, the dispersion guide groove 41 can disperse the lubricating fluid more evenly to each part of the milling cutter head 4, improving the lubrication effect. The milling cutter head 4 is used for milling processing, and its material is selected as cemented carbide material to ensure the hardness and wear resistance of the cutter head and be able to adapt to high-intensity milling work.

[0065] The drill bit body 5 is arranged in the embedding groove 31. The drill bit body 5 is provided with a spiral seat 51, and a drill bit guide hole 85 is opened on the spiral seat 51. The drill bit guide hole 85 is aligned with the lower guide hole 84 to ensure that the lubricating fluid can be smoothly delivered to the corresponding position of the drill bit body 5. The drill bit body 5 is used for drilling processing and is also made of cemented carbide material to meet the requirements for hardness and strength during drilling.

[0066] The support seat 6 is slidably connected inside the embedding groove 31 and is used to support and limit the drill bit body 5. The support seat 6 is provided with a threaded post 61, and the threaded post 61 is threadedly connected to the spiral seat 51 on the drill bit body 5. Through this connection method, both the stability of the installation of the drill bit body 5 can be ensured, and the disassembly and replacement of the drill bit body 5 are convenient, facilitating the replacement of the model of the drill bit body 5. At the same time, the support seat 6 is also provided with a lower guide hole 84, and the lubricating fluid can be sprayed through the lower guide hole 84 to lubricate the drill bit body 5.

[0067] The adjustment unit 7 is arranged between the connecting seat 2 and the support seat 6 and is used to adjust the position of the support seat 6, thereby realizing the adjustment of the extending and retracting states of the drill bit body 5. The adjustment unit 7 includes an adjustment post 71 fixedly connected to the support seat 6 and a locking structure for limiting the adjustment post 71. The adjustment post 71 is provided with a conduit 711, and the conduit 711 is slidably connected inside the main diversion groove 81, ensuring the smoothness of the lubricating fluid delivery.

[0068] The lubrication and diversion unit 8 is used to divert and lubricate the lubricating fluid for the entire drill and milling cutter, including the main diversion groove 81 opened inside the tool handle 1, the inner guide groove 82 arranged inside the adjustment post 71 and communicated with the main diversion groove 81, the side guide groove 83 arranged inside the milling cutter mounting seat 3 and communicated with the embedding groove 31, and the lower guide hole 84 arranged on the support seat 6.

[0069] In addition, the lubrication and diversion unit 8 further includes a convex ring 86 arranged inside the milling cutter mounting seat 3 and a positioning 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 communicated with the embedding groove 31.

[0070] When the drill bit body 5 is in the storage state, the milling cutter head 4 is used for work at this time. The lower guide hole 84 fits with the convex ring 86 to form a closure. 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 provides lubrication for the milling cutter head 4.

[0071] When the drill bit body 5 is in the extended state, the drill bit body 5 is used for work at this time. The lower guide hole 84 is disengaged from the inside 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. The lubricating fluid sprays out from the lower guide hole 84 and automatically lubricates the drill bit body 5. At this time, the lubricating fluid only provides lubrication for the drill bit body 5.

[0072] When the drill bit body 5 is in the extended state and the functions of both the milling cutter head 4 and the drill bit body 5 need to be used simultaneously, the pressure of the lubricating fluid is increased at this time, so that the lubricating fluid fills the lubricating fluid delivery cavity formed between the embedding groove 31, the adjusting column 71 and the support seat 6. The lubricating fluid sprays out from the side guide groove 83 and the lower guide hole 84 respectively, and the lubrication operation for both the milling cutter head 4 and the drill bit body 5 can be realized synchronously.

[0073] Therefore, the drill mill with the integrated milling cutter and drill bit can automatically adjust the delivery path of the lubricating fluid 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 the lubricating fluid, and improve the service performance and life of the tool.

[0090] A limiting rail 73 is arranged on the connecting seat 2, and a second locking bolt 731 is in threaded connection 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 sliding groove 21, the position of the adjusting column 71 can be changed, and further the position of the supporting seat 6 can be changed, so as to realize the adjustment of the state of the drill bit body 5. After the adjustment is in place, the adjusting block 72 is locked by tightening the second locking bolt 731, so as to fix the positions of the adjusting block 72, the adjusting column 71 and the supporting seat 6, and further realize the position locking of the drill bit body 5.

[0095] In the second aspect of the present invention, a production process for a drill-milling cutter integrating a milling cutter and a drill bit is provided. The production process includes the following steps. Step S1, high-strength alloy steel materials are selected for manufacturing the tool shank 1, the connecting seat 2, the milling cutter mounting seat 3, and the support seat 6. The tool shank 1, the connecting seat 2, and the milling cutter mounting seat 3 are processed by integral molding. The support seat 6 and the adjusting column 71 are processed by integral molding. Cemented carbide materials are selected for manufacturing the milling cutter head 4 and the drill bit body 5. Cemented carbide tools can maintain cutting performance for a long time, effectively improving the processing efficiency and quality.

[0096] Step S2, through the casting process, the raw materials are made into the blank shapes of each component. According to the design requirements, the casting process melts the metal material and pours it into a pre-made mold, and the required shape of the blank is obtained after cooling and solidification.

[0097] Step S3, the blanks are subjected to mechanical processing to accurately machine the outer dimensions, hole positions, and slot positions of each component.

[0098] Step S4, the processed components are subjected to a heat treatment process to improve the hardness, strength, toughness, wear resistance and other properties of the components. For high-strength alloy steel components, quenching and tempering processes are adopted. For cemented carbide components, the heat treatment is mainly sintering treatment, and the powdered cemented carbide material is sintered into a dense solid at high temperature to further improve its hardness and wear resistance.

[0099] Step S5, surface treatment and sandblasting passivation treatment are carried out on each component. When carrying out surface treatment on each component, it includes chromium plating and nitriding operations. Chromium plating operation forms a chromium layer with high hardness and good wear resistance on the component surface, improving the corrosion resistance and aesthetics of the component, effectively preventing each component from rusting and corrosion. Nitriding treatment is to place the component in an atmosphere containing nitrogen and heat it to make nitrogen atoms penetrate into the component surface to form a nitriding layer with high hardness, good wear resistance and anti-fatigue, further improving the surface performance of the component. Sandblasting treatment can remove impurities such as scale and oil on the component surface, make the surface rougher, and increase the adhesion of subsequent coatings or platings.

[0100] Step S6, the components that have undergone heat treatment and surface treatment are accurately assembled; before assembly, each component needs to be thoroughly cleaned to remove impurities such as dust and oil on the surface to ensure the fitting accuracy and sealing performance between the components.

[0101] Step S7, during the assembly process, precisely set the structures of each part of the lubrication and diversion unit 8; ensure that the connection between each diversion groove and diversion hole is unobstructed, without blockage and leakage. Debug by introducing a small amount of lubricating fluid into the lubrication and diversion unit 8, check the flow of the lubricating fluid, and make adjustments in a timely manner if there are any abnormalities.

[0102] Step S8, conduct various performance tests on the assembled drill and milling cutter; including dimensional accuracy test, hardness test, wear resistance test, lubrication performance test, etc. For products that fail the tests, conduct a detailed analysis, identify the problems, and take corresponding measures for rework or scrapping.

[0103] Step S9, after completing the performance tests and debugging and all indicators are qualified, conduct packaging and ex-factory of the drill and milling cutter. The packaging materials should have good moisture-proof, rust-proof, and shock-proof properties to protect the drill and milling cutter from damage during transportation and storage. Mark information such as the name, specification, model, production date, etc. of the product on the packaging for users to identify and use. The drill and milling cutter products that have passed strict inspections can be sold ex-factory to provide users with high-quality processing tools.
