Description
A high-precision milling processing equipment for hardware fasteners Technical Field
[0001] This invention relates to the technical field of milling, specifically to a high-precision milling processing device for hardware fasteners. Background Technology
[0002] This high-precision milling equipment for hardware fasteners is based on a high-speed milling machine and a five-axis linkage machining center, equipped with a high-speed electric spindle and a precision servo drive system. The equipment features a high-rigidity bed design, combined with thermal compensation and vibration suppression technology to ensure machining accuracy. Integrating multi-process machining and automatic tool changing functions, and paired with an intelligent CNC system, it can efficiently complete the machining of precision structures such as threads and small holes, adapting to the needs of fastener mass production while balancing machining stability and efficiency.
[0003] For example, patent application CN114211025A discloses a CNC multi-face milling machine for parts processing, including a support plate, a mounting plate and a right-angle fixing plate. The main body is mounted on the top of the support plate, the mounting plate is mounted on one side of the main body, the right-angle fixing plate is mounted on the front of the mounting plate, a high-speed fan is bolted to the front of the right-angle fixing plate, a collection frame is mounted on the back of the mounting plate, an inclined box is mounted on the bottom of the collection frame, and a movable seat is movably mounted on the top of the mounting plate.
[0004] However, the above technical solutions still have some problems. During the cutting process, the milling cutter processes the fastener, generating a lot of chips. In order to ensure that the milling cutter does not generate high temperatures during operation, coolant is introduced during milling. However, the introduction of coolant can cause chips to adhere to the milling cutter, or due to the type of coolant (such as emulsions or semi-synthetic liquids containing electrolytes), micro-batteries can be formed when the fixture comes into contact with the cast iron workpiece. This can lead to pitting or overall corrosion on the workpiece surface, especially at threads, edges, and other gaps, which can affect the connection strength and easily damage the fastener, resulting in the failure of the milling operation.

[0044] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0045] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0046] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0047] This invention discloses a high-precision milling processing equipment for hardware fasteners, as shown in Figures 1-9, comprising:
[0048] The system comprises a milling table 1, a translation mechanism 2, a milling mechanism 6, and a detection mechanism 7 fixedly mounted on the milling table 1, a placement table 3 connected to the translation mechanism 2, a fixture 4 located on the placement table 3 for clamping fasteners, and multiple debris removal units 5 disposed on the placement table 3 and evenly distributed on the fixture 4. Each debris removal unit 5 includes an adjustment component disposed on the placement table 3 and a spraying component 8 disposed on the adjustment component. The spraying component 8 includes a base 81 connected to the adjustment component, a drive module 82 built into the base 81, and a spraying head 83 and a conveying module 9 respectively disposed on the base 81. The drive module 82 pressurizes the coolant in the base 81, allowing the coolant to enter the spraying head 83 through the conveying module 9, thereby intermittently adjusting the spraying speed and angle of the coolant to flush away the debris adhering to the milling cutter and fasteners, reducing the adhesion of debris.
[0049] This device is equipped with multiple cleaning units 5. Some cleaning units 5 are used to spray coating liquid onto the surface or inner wall of the fixture 4, while the remaining cleaning units 5 are used to spray coolant onto the surface of the fastener. By spraying coating liquid onto the surface of the fastener, a protective layer is formed, which prevents the fastener from being damaged due to the formation of micro-batteries during subsequent clamping operations. Through the drive module 82 in the cleaning unit 5, a liquid with a certain impact force can be sprayed intermittently onto the surface of the fixture 4 or the fastener, thereby removing residual chips on the fixture 4, the fastener, or the milling cutter.
[0050] The adjustment assembly includes a rotating shaft 51 and a drive cylinder 53 disposed on the placement platform 3, a rotating block 52 connected to the output end of the drive cylinder 53 and sleeved on the rotating shaft 51, a mounting base 54 disposed on the top of the rotating shaft 51, a propulsion cylinder 55 and two limiting tubes 57 fixedly connected to the mounting base 54, a drive block 56 connected to the output end of the propulsion cylinder 55 and sleeved on the limiting tubes 57, and a support spring 58 for connecting the drive block 56 and the mounting base 54; the base 81 is disposed on the drive block 56.
[0051] When the spraying position of the spraying assembly 8 needs to be adjusted, the drive cylinder 53 starts working. The moving drive cylinder 53 can drive the rotating block 52 to move, which in turn causes the rotating shaft 51 to rotate. The rotating shaft 51 then drives the mounting base 54 to move. At this time, the mounting base 54 can adjust the spraying position of the spraying assembly 8. Then, the push cylinder 55 starts working. The moving push cylinder 55 can drive the drive block 56 to move in the axial direction of the limiting tube 57, thereby adjusting the position of the spraying assembly 8 on the limiting tube 57 and changing the position between the spraying assembly 8 and the workpiece or fixture 4. This allows for focused spraying of the threaded and irregular areas on the fasteners, which not only protects the workpiece or fixture 4 but also avoids the residue of waste chips, ensuring the smooth progress of subsequent installation or milling work.
[0052] The drive module 82 includes a drive unit 821 mounted on the base 81, a drive rod 822 connected to the output end of the drive unit 821, a first drive gear 823 meshing with the teeth on the drive rod 822, a first rotating rod 824 mounted on the first drive gear 823, and a pusher and a rotating member respectively mounted at both ends of the first rotating rod 824. The base 81 also includes a one-way valve. The pusher includes a cam 825 connected to the first rotating rod 824, a movable rod 826 movably connected to the distal end of the cam 825, a connecting rod 827 movably connected to the movable rod 826, a pressing seat 829 mounted on the connecting rod 827, and a chamber 8210 formed in the base 81. A sealing gasket 828 is provided in the chamber 8210 and fitted inside the pressing seat 829. A pusher disc is also provided on the pressing seat 829. The one-way valve is used to deliver coolant into the chamber 8210.
[0053] During the normal application of coolant, the pump body operates to allow coolant or the solution to be delivered to enter the chamber 8210 through a one-way valve. As the amount of liquid in the chamber 8210 increases, the water pressure in the chamber 8210 causes the delivery module 9 to move, allowing the liquid to enter the nozzle 8310 along the delivery module 9 to complete the spraying or coating of the agent. During this process, the nozzle 8310 is connected to the input pipe 96 through a hose.
[0054] When pressurized spraying is required, the drive unit 821 (existing technology) starts working. The moving drive unit 821 can drive the drive rod 822 to rotate. Then, the tooth groove on the drive rod 822 can drive the first drive gear 823 to rotate. In turn, the moving first drive gear 823 can drive the first rotating rod 824 to rotate, thereby driving the propulsion member and the rotating member to work. When the propulsion member starts working, the one-way valve is in the closed state. Then, the moving propulsion member can pressurize the liquid in the chamber 8210, thereby accelerating its outflow and spraying. This can reduce the residue of waste chips while cooling the milling cutter or fastener.
[0055] In a further embodiment, the device includes a conventional coating mode: that is, the liquid is supplied naturally by the pressure of the pump body and the chamber 8210 to meet the low-pressure, uniform coating scenarios, such as the conventional cooling of milling cutters and the application of anti-rust coatings on the surface of fasteners.
[0056] Another mode is the pressurized spray mode: the liquid in the chamber 8210 is pressurized by the mechanical structure linked by the drive unit 821 to achieve high-pressure, high-speed spraying, which is suitable for scenarios such as enhanced cooling and waste washing when milling cutters are cutting at high speed. No additional pressurization device is required, and one device can cover multiple working conditions. At the same time, this device can switch between conventional coating and pressurized spraying simply by starting and stopping the drive unit 821. The operation logic is simple and there is no need for complicated pipeline switching or parameter adjustment.
[0057] The rotating component includes a first helical gear 8212 connected to the other end of the first rotating rod 824, a second helical gear 8213 meshing with the first helical gear 8212, a second rotating rod 8211 disposed on the second helical gear 8213 and movably connected to the base 81, and a first bevel gear 8214 sleeved on the second rotating rod 8211.
[0058] When the pusher starts working, the first rotating rod 824 drives the cam 825 to move. The moving cam 825 then drives the movable rod 826 to move. The movable rod 826, through the connecting rod 827 hinged to it, drives the extrusion seat 829 to move. The moving extrusion seat 829 can change the capacity of the chamber 8210, thus pressurizing the liquid in the chamber 8210 and causing it to be discharged instantaneously. This completes the instantaneous cooling and cleaning of the workpiece or milling cutter. Simultaneously, through the structure of the cam 825, it can perform intermittent pressurization and cleaning, operating autonomously without manual intervention. This system effectively removes waste chips, preventing them from remaining on the milling cutter and causing milling failure. Simultaneously, the cam 825 structure drives the extrusion seat 829 to achieve intermittent pressurized spraying. The high-pressure liquid stream pulses against the workpiece or milling cutter surface, providing a stronger impact force compared to continuous pressurization. This more efficiently removes stubborn waste chips (such as iron or aluminum chips from milling), preventing chip accumulation and ensuring higher machining accuracy. It also avoids damage to the threads or body of the milling cutter or workpiece (fastener) caused by prolonged high-speed scouring. Furthermore, the pulse intervals allow the chips to fall off naturally and be quickly carried away by the high-pressure liquid stream, ensuring efficient chip removal without affecting milling accuracy.
[0059] The rotating component further includes a second bevel gear 8215 meshing with the first bevel gear 8214, a rotating rod 8216 disposed on the second bevel gear 8215, a first drive disk 8217 connected to the rotating rod 8216, and a second drive disk 8218 meshing with the first drive disk 8217; the second drive disk 8218 is provided with a plurality of connecting holes, the connecting holes being connected to the conveying module 9 through pipes; the spray head 83 is disposed on the second drive disk 8218;
[0060] When the first rotating rod 824 rotates, it can also drive the first helical gear 8212 to rotate. Then, the first helical gear 8212 drives the second rotating rod 8211 to rotate through the second helical gear 8213. Then, through the cooperation of the first bevel gear 8214 and the second bevel gear 8215, the rotating rod 8216 can be driven to rotate, which in turn drives the first drive disk 8217 and the second drive disk 8218 to move. At this time, the second drive disk 8218 can drive the conveying module 9 and the spray head 83 to rotate. Through the first drive disk 8217 and the second drive disk 8218, the position of the spray head 83 can be adjusted when spraying coolant or rust inhibitor, thereby expanding the spray position of the solution and completing the corresponding waste removal and protection of the clamp 4.
[0061] By working the rotating parts, the spray head 83 can be adjusted in multiple angles and positions. This not only expands the spray range, but also allows for precise control of the rotation angle of the spray head 83 through the meshing transmission of the drive disc, enabling fixed-point spraying, fan-shaped spraying, or switching between the two. This adapts to workpieces of different sizes and shapes, such as irregularly shaped milled parts or fixtures 4, and avoids spray blind spots.
[0062] Meanwhile, the linkage design between the rotation of the drive disc and the spray head 83 enables multi-dimensional spraying, further improving the uniformity of solution coverage. It is especially suitable for removing debris and protecting against rust in difficult-to-clean areas such as gaps in the fixture 4 and deep cavities of the workpiece.
[0063] When the spray head 83 rotates with the second drive disc 8218, it can be combined with the intermittent pressurization of the propulsion component to form a rotating pulse spray mode, which not only expands the coverage area but also enhances the local impact effect. At the same time, it allows the rust inhibitor to be evenly adhered to the surface of the fixture 4, avoiding the risk of corrosion caused by local missed coating.
[0064] The conveying module 9 includes a connecting base 91 fixedly connected to the second drive disk 8218, an input pipe 96 disposed on the connecting base 91, an adjusting knob 92 screwed to the connecting base 91, an adjusting member connected to the adjusting knob 92, and a sealing ball 95 connected to the adjusting member; the sealing ball 95 abuts against the output end of the input pipe 96; the communicating hole is connected to the input pipe 96; the adjusting knob 92 has a T-shaped structure; the adjusting member includes an adjusting tube 94 sleeved on the adjusting knob 92, the adjusting tube 94 having a groove adapted to the adjusting knob 92, the adjusting knob 92 being inserted into the groove, and an adjusting spring 93 for connecting the adjusting knob 92 and the adjusting tube 94; the connecting base 91 also has an outlet end, and the adjusting tube 94 has a placement groove for placing the sealing ball 95;
[0065] When coolant or rust inhibitor is to be sprayed, the hydraulic pressure in the chamber 8210 increases, causing the solution to push the sealing ball 95 to move. The moving sealing ball 95 moves away from the input pipe 96, causing the adjusting spring 93 to deform. As a result, the solution can be discharged from the outlet end of the delivery module 9 and transported to the spray head 83 along the hose, where it works with the spray head 83 to complete the spraying of the solution.
[0066] The spray head 83 includes a mounting bracket 831 fixedly mounted on the base 81, an input shaft 832 connected to the mounting bracket 831, a rotating frame 833 connected to the input shaft 832 and movably connected to the mounting bracket 831, a transmission component disposed at the connection between the rotating frame 833 and the mounting bracket 831, and a spray head 8310 connected to the transmission component and located on the rotating frame 833; the input shaft 832 is connected to a second drive disk 8218; the transmission component includes a fixed gear 835 disposed on the mounting bracket 831, and a spray head 8310 connected to the fixed gear 831. The rotating frame 833 includes a moving gear 834 meshing with wheel 835, a transmission shaft 839 connected to the moving gear 834 and rotatably mounted on the rotating frame 833, a third bevel gear 836 connected to the other end of the transmission shaft 839, a fourth bevel gear 837 meshing with the third bevel gear 836 and mounted on the rotating frame 833, and a support shaft 838 positioned between the rotating shaft 51 and the nozzle 8310; one of the support shafts 838 is connected to the fourth bevel gear 837, and a certain gap is reserved between the nozzle 8310 and the inner wall of the rotating frame 833.
[0067] When the second drive disc 8218 starts working, the moving second drive disc 8218 can drive the input shaft 832 mounted on it to rotate, and the moving input shaft 832 can drive the rotating frame 833 to rotate. At this time, the rotating frame 833 can rotate, so that the moving gear 834 and the fixed gear 835 are relatively displaced. At this time, the moving gear 834 can drive the transmission shaft 839 to move, and then the moving transmission shaft 839 can drive the third bevel gear 836 to rotate. Then, the moving third bevel gear 836, through the cooperation of the fourth bevel gear 837, drives the support shaft 838 to rotate, so that the nozzle 8310 can swing. Therefore, the position of the nozzle 8310 can be adjusted by the movement of the rotating frame 833 and the support shaft 838, and the spraying area of the nozzle 8310 can be changed to complete the cleaning and cooling of fasteners or milling cutters.
[0068] The nozzle 8310 in this device can perform a composite motion trajectory of revolution and rotation, so that the sprayed liquid flow is spiral or all-round coverage, completely eliminating blind spots that are difficult to reach by traditional spraying, such as deep cavities of workpieces, fastener thread gaps, and the root of milling cutter cutting edges; during operation, the distance and angle between the nozzle 8310 and the workpiece or milling cutter surface are dynamically optimized at all times, avoiding excessively high spray intensity in local areas to prevent solution waste or too low intensity, and ensuring that every part can obtain uniform liquid flow impact and medium coverage;
[0069] The transmission components achieve power transmission through gear meshing, and the oscillation speed and revolution speed are synchronized, resulting in a stable motion rhythm. This avoids inconsistent spray intensity caused by uncoordinated movement, making it particularly suitable for scenarios where consistent anti-corrosion coating thickness is required.
[0070] Working principle description: When it is necessary to adjust the spray position of the spray assembly 8, the drive cylinder 53 starts to work. The moving drive cylinder 53 can drive the rotating block 52 to move, so the moving rotating block 52 can make the rotating shaft 51 rotate. Then the moving rotating shaft 51 can drive the mounting base 54 to move. At this time, the mounting base 54 can adjust the spray position of the spray assembly 8. Then the push cylinder 55 starts to work. The moving push cylinder 55 can drive the drive block 56 to move in the axial direction of the limiting tube 57, thereby adjusting the position of the spray assembly 8 on the limiting tube 57.
[0071] During the normal application of coolant, the pump body operates to allow coolant or the solution to be delivered to enter the chamber 8210 through a one-way valve. As the amount of liquid in the chamber 8210 increases, the water pressure in the chamber 8210 causes the delivery module 9 to move, allowing the liquid to enter the nozzle 8310 along the delivery module 9 to complete the spraying or coating of the agent. During this process, the nozzle 8310 is connected to the input pipe 96 through a hose.
[0072] When pressurized spraying is required, the drive unit 821 (existing technology) starts working. The moving drive unit 821 can drive the drive rod 822 to rotate. Then, the tooth groove on the drive rod 822 can drive the first drive gear 823 to rotate. In turn, the moving first drive gear 823 can drive the first rotating rod 824 to rotate, thereby driving the propulsion member and the rotating member to work. When the propulsion member starts working, the one-way valve is in the closed state. Then, the moving propulsion member can pressurize the liquid in the chamber 8210, thereby accelerating its outflow and spraying. This can reduce the residue of waste chips while cooling the milling cutter or fastener.
[0073] When the pusher starts working, the first rotating rod 824 can drive the cam 825 to move, and then the moving cam 825 can drive the movable rod 826 to move. At this time, the moving movable rod 826 drives the extrusion seat 829 to move through the connecting rod 827 hinged to it. At this time, the moving extrusion seat 829 can change the capacity of the chamber 8210. At this time, the extrusion seat 829 can pressurize the liquid in the chamber 8210, so that it can be discharged from the chamber 8210 instantly, completing the instantaneous cooling and cleaning of the workpiece or milling cutter.
[0074] When the first rotating rod 824 rotates, it can also drive the first helical gear 8212 to rotate. Then, the first helical gear 8212 drives the second rotating rod 8211 to rotate through the second helical gear 8213. Then, through the cooperation of the first bevel gear 8214 and the second bevel gear 8215, the rotating rod 8216 can be driven to rotate, which in turn drives the first drive disk 8217 and the second drive disk 8218 to move. At this time, the second drive disk 8218 can drive the conveying module 9 and the spray head 83 to rotate. Through the first drive disk 8217 and the second drive disk 8218, the position of the spray head 83 can be adjusted when spraying coolant or rust inhibitor, thereby expanding the spray position of the solution and completing the corresponding waste removal and protection of the clamp 4.
[0075] When it is necessary to spray coolant or rust inhibitor, as the hydraulic pressure in the chamber 8210 increases, the solution can push the sealing ball 95 to move. The moving sealing ball 95 can then move away from the input pipe 96. At this time, the adjusting spring 93 deforms, and the solution can be discharged from the outlet end of the delivery module 9.
[0076] When the second drive disc 8218 starts working, the moving second drive disc 8218 can drive the input shaft 832 mounted on it to rotate. In turn, the moving input shaft 832 can drive the rotating frame 833 to rotate. At this time, the rotating frame 833 can rotate, thereby causing relative displacement between the moving gear 834 and the fixed gear 835. The moving gear 834 can drive the transmission shaft 839 to move. Then, the moving transmission shaft 839 can drive the third bevel gear 836 to rotate. In turn, the moving third bevel gear 836, through the cooperation of the fourth bevel gear 837, drives the support shaft 838 to rotate, thereby causing the nozzle 8310 to swing. Therefore, the position of the nozzle 8310 can be adjusted by the movement of the rotating frame 833 and the support shaft 838, changing the spraying area of the nozzle 8310, and completing the cleaning and cooling of fasteners or milling cutters.
