Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to a precision CNC machine tool for multi-hole hardware parts. Background Technology

[0002] Multi-hole hardware is a basic component in the fields of mechanical manufacturing and precision equipment assembly. The machining accuracy and consistency of its multi-hole positions directly affect the assembly accuracy and stability of the whole machine. At present, the industry generally uses special CNC machine tools to complete the multi-hole drilling operation of hardware. Relying on automated drilling equipment to replace manual processing can effectively improve the processing efficiency of multi-hole hardware.

[0003] In existing technologies, precision CNC machine tools used for machining multi-hole hardware parts mainly rely on multi-axis moving mechanisms to drive the drill bit to complete point switching and feed drilling. A cutting fluid spray structure is used to lubricate and cool the machining points, and a simple waste collection structure is also provided to achieve automated drilling of hardware parts. However, existing precision CNC machine tools still have certain shortcomings in practical applications: Firstly, the existing equipment has a relatively simple drilling lubrication structure, and the cutting fluid is mostly sprayed directly, which cannot fully coat and wet the drill bit. The drill bit wears unevenly during processing, and long-term processing can easily lead to problems such as chipping and breakage. The drill bit has a short service life and lacks preheating and post-processing air cooling protection structures, which cannot well adapt to the processing protection needs of hardware parts of different materials. Secondly, the existing equipment has an imperfect structure for cleaning and filtering debris and waste liquid, which makes it easy for debris and waste liquid to remain in the processing area, affecting the cleanliness and accuracy of the processing. Third, the existing equipment has poor adaptability of hardware clamping fixtures, making it difficult to simultaneously clamp and fix hardware of different shapes and specifications, such as round and rectangular, and its versatility is insufficient. Fourth, existing equipment lacks a sound workpiece material verification and working condition adaptive adjustment mechanism, and cannot automatically identify the hardware material and match the corresponding processing power, resulting in poor energy efficiency and low fault tolerance.

[0015] Compared with the prior art, the present invention provides a precision CNC machine tool for porous hardware parts, which has the following advantages: 1. This precision CNC machine tool for multi-hole hardware parts, in conjunction with the controller on the machine body, activates the second linear module, causing the third linear module to move laterally. The third linear module, in turn, causes the drilling machine to move up and down. Activating the drilling machine causes the drill bit to rotate at high speed, enabling multi-hole processing of hardware parts. With the addition of a liquid inlet pipe and a bamboo-joint tube, the nozzle orientation can be easily adjusted, allowing cutting fluid to be sprayed during drilling. A cleaning component, along with a connecting rod fixing the cylindrical cover, has a conical structure that prevents cutting fluid and debris from splashing. Combined with the curved pipe on the side rod, opening the first solenoid valve on the main pipe allows the cutting fluid to be drawn out through the cylinder during drilling. The cutting fluid sprayed obliquely downwards towards the drill bit is partially drawn upwards by the cylinder, thus fully wetting the outside of the drill bit and improving drilling results.

[0016] 2. This precision CNC machine tool for porous hardware parts, by setting up a filter assembly and cooperating with the coil spring outside the fixed rod, allows the ring block to fit against the fixed ring without external force, so that the filter plate blocks the opening of the fixed ring. Thus, when the cleaning assembly is running, the negative pressure suction can make the ring block and the fixed ring fit more firmly, preventing the debris generated by drilling from being sucked into the curved tube. With the help of the baffle, the gas flow area of ​​the filter plate can be reduced, so that the ring block can be better suctioned.

[0017] 3. This precision CNC machine tool for multi-hole hardware parts, by setting up a protective component, allows for the preheating of the drill bit by blowing hot air through the cylinder before drilling, by activating the second solenoid valve on the hot air pipe, closing the second solenoid valve on the cold air pipe, and closing the first solenoid valve. This helps improve the temperature state of the drill bit before and after processing and reduces the risk of damage caused by temperature differences or local overheating. When the second solenoid valve on the hot air pipe is closed, the second solenoid valve on the cold air pipe is opened, and the first solenoid valve is closed, cold air is blown through the cylinder to cool the drill bit after it finishes working, which also improves the life of the drill bit. In both hot and cold air modes, the cylinder can blow the ring block and filter plate away from the fixed ring to avoid obstruction of the hot and cold air flow. The staggered baffles further facilitate the better blowing of the ring block.

[0018] 4. This precision CNC machine tool for multi-hole hardware parts, by setting auxiliary components, when the drill bit is machining the hole, works with the auxiliary tube and the annular tube to make the internal negative pressure environment of multiple sets of circumferentially arrayed suction nozzles synchronously generate, thereby removing cutting fluid and chips from all directions, keeping the working area clean and improving processing efficiency.

[0019] 5. This precision CNC machine tool for multi-hole hardware parts, by setting a fixed component, when the first linear module is started, the hopper can move longitudinally. With the inclined surface of the hopper, the falling waste liquid and waste residue are better discharged to the slag discharge hood. With the subsequent manual pushing and cleaning, the waste liquid and waste residue are discharged to the collection trough. When the first hydraulic cylinder is started, the support plate is located inside the hopper to provide initial support for the hardware parts. When the second hydraulic cylinder is started, the two clamping plates move towards each other.

[0020] 6. This precision CNC machine tool for multi-hole hardware parts, by setting an adjustment component, moves fasteners inside the through slot, fixes the bent plate at the target position, and adjusts the distance between the bent plates to accommodate more sizes of hardware parts. Thus, when the two sets of clamping plates drive the corresponding bent plates to move closer to each other, the inclined outer walls of multiple sets of bent plates can jointly clamp and fix the circular hardware parts, and the vertical outer walls of multiple sets of bent plates can jointly clamp and fix the rectangular hardware parts, improving adaptability. With the first hydraulic cylinder, the support plate is removed from the bucket, and with the help of multiple sets of pads, the hardware parts can be supported together, so that the drill bit can process them better.

[0021] 7. This precision CNC machine tool for multi-hole hardware parts, after the hardware parts are fixed by the fixing components, can perform auxiliary verification and detection of the hardware material in conjunction with the inductive sensor and eddy current sensor in the sensor group. It can also be used for wiring and heat dissipation with the wiring channel and for protection with the protective plate. When the material does not meet the preset material, the alarm will sound an audible and visual alarm and stop the subsequent processing. When the material is verified to be in compliance, the operating power of the protection components will be controlled according to different materials, thereby making it more energy-efficient.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0026] Please see Figures 1-12 The present invention provides a technical solution: Example 1 A precision CNC machine tool for multi-hole hardware parts includes a machine body 1. The machine body 1 is equipped with a moving mechanism that drives a drill bit 25 to move in multiple axes to drill holes in the hardware parts. The moving mechanism includes a first linear module 21, which is fixedly mounted on the upper surface of the bottom end of the machine body 1. A controller 11 is also fixedly mounted on the upper surface of the bottom end of the machine body 1. An alarm 12 and a second linear module 22 are fixedly mounted on the top end of the machine body 1. A third linear module 23 is fixedly mounted on the moving part of the second linear module 22. A drilling machine 24 is fixedly mounted on the moving part. The output end of the drilling machine 24 is fixedly connected to the drill bit 25. The drill bit 25 is provided with a lubrication mechanism for outputting cutting fluid. In addition, the lubrication mechanism includes an inlet pipe 31, which is fixedly mounted on the moving part of the third linear module 23. A bamboo tube 32 is fixedly mounted on the output end of the inlet pipe 31, and a nozzle 33 is fixedly mounted on the output end of the bamboo tube 32. The opening end of the nozzle 33 faces the drill bit 25. The input end of the inlet pipe 31 is connected to the output end of the cutting fluid supply equipment through a hose.

[0027] The machine body 1 is provided with a fixing component 8, which includes a bottom bucket 81. The bottom bucket 81 is fixedly installed on the top of the moving part of the first linear module 21. The bottom end of the bottom bucket 81 is set as an inclined surface, and a slag discharge hood 82 is integrally formed near the bottom end of the bottom bucket 81. A material collection trough 83 is snapped onto the upper surface of the bottom of the machine body 1. The material collection trough 83 is located directly below the moving trajectory of the slag discharge hood 82. A first hydraulic cylinder 84 is fixedly installed at the rear end of the bottom bucket 81. A support plate 85 for placing hardware parts is fixedly installed at the piston end of the first hydraulic cylinder 84. The support plate 85 is slidably installed inside the side wall of the bottom bucket 81. A second hydraulic cylinder 86 is fixedly installed on both sides of the bottom bucket 81. A clamping plate 87 is fixedly installed after the piston end of the second hydraulic cylinder 86 penetrates the side wall of the bottom bucket 81.

[0028] In this embodiment, after the equipment is powered on and initialized, the operator places the hardware parts to be processed on the support plate 85 in advance. The controller 11 drives the second hydraulic cylinder 86 to start, and the piston end is precisely extended and retracted by relying on the hydraulic transmission principle. The two second hydraulic cylinders 86 can receive the symmetrical control signals of the controller 11 at the same time, and drive the clamping plates 87 on both sides to move in opposite directions at a uniform speed, so as to complete the automatic centering, clamping and loosening of the hardware parts. The hydraulic drive method can ensure uniform clamping force and avoid deformation of hardware parts caused by rigid clamping. The controller 11 outputs control signals to drive the first linear module 21 to start running. Its built-in asynchronous motor receives the signal from the controller 11, controls the number of rotations and direction of the lead screw, and drives the slide rail slider and the top moving part to make precise longitudinal linear displacement. It is equipped with a closed-loop position sensor to transmit position data in real time, so as to achieve precise start, stop and positioning. It is mainly used to adjust the longitudinal position of the bucket 81.

[0029] The equipment officially enters the drilling process. Controller 11 coordinates the movement of multiple linear modules. The second linear module 22 operates on the same principle as the first linear module 21, using an asynchronous motor, lead screw, and slide rail transmission in conjunction with a position sensor for closed-loop control. It is specifically responsible for the precise displacement of the horizontal axis, receiving position pulse signals from controller 11 to drive the third linear module 23, drilling machine 24, and drill bit 25 to complete the horizontal hole position switching, enabling drilling of hardware parts in different horizontal positions. The third linear module 23 is a vertical lifting axis precision transmission module, controlled by controller 11, achieving high-precision vertical feed and tool lifting actions. It can control the drilling depth, feed speed, and retraction stroke of drill bit 25, ensuring drilling depth accuracy. With the multi-axis linkage of the second linear module 22 for lateral movement and the third linear module 23 for longitudinal feed, the drill bit 25 achieves three-dimensional precise movement, adapting to the needs of multi-hole processing of hardware parts. At the same time, the drilling machine 24 receives the processing signal from the controller 11 and switches to high-speed operation mode, driving the drill bit 25 to rotate at high speed. Relying on the high-speed rotation cutting force, it continuously drills and cuts the metal material of the hardware parts. During the processing, the cutting fluid supply equipment delivers cutting fluid through the inlet pipe 31. The operator can flexibly adjust the bending angle of the bamboo tube 32 in advance and change the spray direction of the nozzle 33 so that the cutting fluid is sprayed towards the processing contact position between the drill bit 25 and the hardware parts, so as to achieve continuous lubrication, cooling and chip removal at the processing point, and reduce drilling wear and processing burrs.

[0030] The controller 11 controls all actuators to reset sequentially: the first linear module 21, the second linear module 22, and the third linear module 23 return to their initial reference positions; the first hydraulic cylinder 84 resets to receive material; the second hydraulic cylinder 86 resets to release material; the waste liquid and slag that fall during processing fall into the bottom hopper 81 (which is conical in shape); relying on the guiding effect of the inclined surface inside the bottom hopper 81, the waste liquid and slag are automatically guided out of the slag cover 82 and finally flow into the collection tank 83 for centralized collection; the waste inside the collection tank 83 can be cleaned by hand at regular intervals to complete a single complete automated processing cycle; the equipment then stands by and waits for the next processing instruction.

[0031] Example 2 See Figures 5-7 Based on embodiment 1, the clamping plate 87 is provided with an adjustment component 9. The adjustment component 9 includes a through groove 91. The clamping plate 87 has a through groove 91. A bent plate 93 is fixedly installed on the clamping plate 87 by fasteners 92 (including screws, nuts and washers). The bent plate 93 is Z-shaped. The fasteners 92 pass through the through groove 91. A pad 94 is integrally formed at the bottom of the bent plate 93. Two sets of through grooves 91, fasteners 92, bent plates 93 and pads 94 are provided on a single clamping plate 87 to improve adaptability.

[0032] In this embodiment, the operator can move the fastener 92 in advance inside the through groove 91 of the clamping plate 87 according to the specifications of the hardware parts, adjust the installation position of the bending plate 93, change the distance between the two sets of bending plates 93, and use the inclined outer wall of the bending plate 93 to adapt to clamp the round hardware parts and the vertical outer wall to adapt to clamp the rectangular hardware parts, so as to complete the adaptive fixing of hardware parts of different specifications. At the same time, the pad plate 94 provides auxiliary support for the bottom of the hardware parts, improving the clamping stability. During the processing, the first hydraulic cylinder 84 can be controlled to drive the support plate 85 out of the bottom bucket 81, and the hardware parts are completely supported by the pad plate 94, eliminating the interference of the support plate 85 with the drilling stroke and ensuring the drilling accuracy.

[0033] Example 3 See Figure 2 , Figures 8-11Based on embodiments 1-2, a cleaning component 4 is provided on the body 1. The cleaning component 4 includes a connecting rod 41. A circular cover 42 is fixedly installed at one end of the connecting rod 41. The circular cover 42 is conical. An inlet pipe 31 passes through the circular cover 42. A drill bit 25 passes through the center of the small end of the top of the circular cover 42. A bent pipe 44 is fixedly installed on the inner wall of the circular cover 42. A main pipe 45 is fixedly installed at one end of the bent pipe 44. A first solenoid valve 46 is provided on the main pipe 45. A cylinder 47 is fixedly installed at the end of the bent pipe 44 near the drill bit 25. The open end of the cylinder 47 faces the drill bit 25 at an angle. The end of the main pipe 45 away from the bent pipe 44 is connected to the input end of the negative pressure suction device through a hose. The end of the connecting rod 41 away from the circular cover 42 is fixedly installed on the moving part of the third linear module 23. A side rod 43 is fixedly installed between the moving part of the third linear module 23 and the bent pipe 44. The cylinder 47 and the nozzle 33 are arranged opposite to each other on the radial sides of the drill bit 25, so that the drilling effect is better.

[0034] In this embodiment, the cleaning component 4 and auxiliary component 7 work together to clean the drilling process synchronously. The connecting rod 41 fixes and supports the dome 42. The conical structure of the dome 42 blocks the cutting fluid and debris from splashing outward, thus isolating and protecting the processing area. The controller 11 controls the first solenoid valve 46 to open, opening the pipeline passage between the main pipe 45 and the bend 44. The negative pressure suction device draws air through the pipeline, creating a stable negative pressure environment inside the cylinder 47. The cutting fluid sprayed obliquely downward onto the drill bit 25 is partially sucked back by the negative pressure obliquely upward by the cylinder 47, allowing the cutting fluid to fully coat and wet the outside of the drill bit 25, further optimizing the drilling lubrication and cooling effect and improving drilling accuracy.

[0035] Example 4 See Figure 1 , Figure 8 Based on embodiments 1-3, a protective component 6 is provided on the outside of the drill bit 25. The protective component 6 includes a hot air pipe 61 and a cold air pipe 62. The hot air pipe 61 and the cold air pipe 62 are fixedly installed and connected to both sides of the main pipe 45. A second solenoid valve 63 is provided on both the hot air pipe 61 and the cold air pipe 62. The two second solenoid valves 63 are located between the bend pipe 44 and the first solenoid valve 46. The input ends of the hot air pipe 61 and the cold air pipe 62 are respectively connected to the output ends of the equipment that supplies hot air and cold air.

[0036] In this embodiment, before the formal drilling process, the equipment enters a pre-processing stage. The controller 11 outputs a level signal to control various solenoid valves to complete the state switching. Among them, the first solenoid valve 46 is an electromagnetic on / off control valve. During the preheating stage, the controller 11 controls the first solenoid valve 46 to de-energize and close, cutting off the negative pressure suction passage. It also controls the second solenoid valve 63 matched with the hot air pipe 61 to be energized and opened, and the second solenoid valve 63 matched with the cold air pipe 62 to be de-energized and closed, thus separately opening the hot air passage. The hot air equipment delivers constant temperature hot air through the hot air pipe 61. The hot air is ejected through the main pipe 45 and the cylinder 47. The controller 11 synchronously controls the drilling machine 24 to start and stop at low speed. The drilling machine 24 operates on the principle of relying on the built-in servo motor to drive the spindle to rotate at high speed. The speed and torque can be precisely adjusted. During the preheating stage, the drill bit 25 is controlled to operate at a low speed, which drives the drill bit 25 to rotate at a uniform and slow speed. This allows the hot air to wrap around the drill bit 25 in all directions without dead angles, achieving uniform hot air preheating. The hot air flow acts on the filter component 5, and the air flow thrust pushes the ring block 52 to overcome the elastic force of the external coil spring of the fixed rod 51, causing the ring block 52 to separate from the fixed ring 53. At the same time, the baffle 55 optimizes the airflow force through the staggered layout structure, ensuring that the ring block 52 and the filter plate 54 can smoothly move away from the fixed ring 53, avoiding the hot air flow being blocked and ensuring smooth hot air circulation. The preheating operation can improve the metal plasticity of the drill bit 25, which is beneficial to improve the temperature state of the drill bit 25 before and after processing and reduce the risk of damage caused by temperature difference or local overheating. After a batch of hardware parts is drilled, the controller 11 switches the equipment operating conditions, closes the first solenoid valve 46 to cut off the negative pressure pipeline, and simultaneously switches the working state of the second solenoid valve 63, closing the second solenoid valve 63 corresponding to the hot air pipe 61 and opening the second solenoid valve 63 corresponding to the cold air pipe 62, thus separately opening the cold air passage. The cold air equipment delivers low-temperature cold air through the cold air pipe 62, which is continuously sprayed onto the drill bit 25, which is in a low-speed rotating state, through the main pipe 45 and the cylinder 47. This rapidly and evenly cools the drill bit 25, which is in a high-temperature state after high-speed processing, quickly releases the processing stress of the drill bit 25, avoids high-temperature annealing and fatigue damage of the drill bit 25, and significantly extends the service life of the drill bit 25.

[0037] Example 5 See Figure 1 , Figure 8 and Figure 10 Based on embodiments 1-3, an auxiliary component 7 is also provided on the outside of the drill bit 25. The auxiliary component 7 includes an auxiliary tube 71, which is fixedly installed inside the side rod 43. A circular tube 72 is fixedly installed at one end of the auxiliary tube 71 and at the bottom of the circular cover 42. The other end of the auxiliary tube 71 is connected to the input end of the negative pressure suction device through a hose. A suction nozzle 73 is fixedly installed at the bottom end of the circular tube 72. There are eight sets of suction nozzles 73, and the eight sets of suction nozzles 73 are evenly distributed along the circumference with the central axis of the circular tube 72 or the axis of the drill bit 25 as the array center, so as to achieve better cleaning effect.

[0038] In this embodiment, the auxiliary pipe 71 fixedly supported by the side rod 43 is connected to the negative pressure suction device, so that multiple sets of suction nozzles 73 distributed in a circular array at the bottom of the annular pipe 72 generate negative pressure simultaneously, which removes the cutting fluid splashed and the falling debris from the processing area in all directions, cleans the processing impurities without dead corners, keeps the working area clean, avoids the accumulation of debris from affecting the processing accuracy, and effectively improves the overall processing efficiency.

[0039] Example 6 See Figure 1 , Figure 11 and Figure 12 Based on embodiments 1-4, a filter assembly 5 is provided on the cylinder 47. The filter assembly 5 includes a fixing rod 51, which is fixedly installed inside the cylinder 47. A ring block 52 is rotatably installed on the outside of the fixing rod 51 via a coil spring. A fixing ring 53 is integrally formed inside the cylinder 47. The outer diameter of the ring block 52 and the inner diameter of the fixing ring 53 are matched. A filter plate 54 is snapped into the inside of the ring block 52 to intercept debris. In addition, a baffle 55 is snapped into the outside of the filter plate 54. Two sets of filter plates 54 and baffles 55 are provided. The two baffles 55 are staggered in the central axial direction of the ring block 52, so that the ring block 52 can be pushed better.

[0040] In this embodiment, during the negative pressure suction operation of the cleaning component 4, the filter component 5 continuously operates to intercept and protect against debris. Under normal negative pressure suction, the external coil spring of the fixing rod 51 drives the circular block 52 to adhere to the fixing ring 53, and the filter plate 54 seals the opening of the fixing ring 53, filtering the airflow inside the suction bend 44, intercepting fine metal debris generated during drilling, and preventing debris from entering the negative pressure pipeline and causing pipeline blockage and internal wear of the equipment, thus ensuring the long-term stable operation of the cleaning equipment. The baffle 55 can reduce the gas flow area of ​​the filter plate 54, effectively increasing the adsorption force of the negative pressure on the circular block 52, making the circular block 52 and the fixing ring 53 fit more tightly, preventing impurities from leaking out, and enhancing the filtration and interception effect. Under the condition of hot air preheating in the early stage and cold air cooling in the later stage, The positive airflow thrust can stably push the annular block 52 and filter plate 54 apart, automatically release the blockage, eliminate airflow resistance, ensure smooth temperature control, and achieve adaptive switching between filtration and ventilation conditions. The same applies to the cold air operation process. The positive airflow pushes the annular block 52 and filter plate 54 of the filter assembly 5 away from the fixed ring 53, ensuring smooth cold air flow without any cooling dead zones. After the cooling and maintenance operation is completed (specifically: the negative pressure direction is from the opening end of the cylinder 47 to the bend 44, the coil spring makes the annular block 52 cover the flow port of the fixed ring 53, and the filter plate 54 allows airflow to pass through and intercepts debris; the positive pressure direction is from the bend 44 to the opening end of the cylinder 47, the airflow acts on the windward side of the baffle 55, causing the annular block 52 to rotate around the fixed rod 51 and open the flow port).

[0041] Example 7 See Figures 6-7 Based on embodiments 1-4, a sensor group 95 is fixedly installed inside the piston end of the second hydraulic cylinder 86, and a wiring groove 96 is opened inside the piston end of the second hydraulic cylinder 86. A protective plate 97 is fixedly installed on the outer wall of the center of the clamping plate 87, and the protective plate 97 is located above the sensor group 95. The sensor group 95 includes an inductive sensor and an eddy current sensor to verify the material type of the hardware parts input by the operator. The machine body 1 is also provided with an information input module electrically connected to the controller 11, which is used to receive the preset material information of the hardware parts input by the operator; a preset information storage module is used to store the preset material information and the associated material standard signal characteristics; the controller 11 is configured to: acquire the detection signal of the sensor group 95, and compare the detection signal with the material standard signal characteristics in the preset information storage module to verify whether the current hardware part material matches the preset material information input by the operator; if they do not match, the alarm 12 is controlled to sound an alarm and the processing is stopped.

[0042] In this embodiment, after the hardware is clamped and fixed, the controller 11 triggers the sensor group 95 to power on. The inductive sensor integrated in the sensor group 95 works based on the principle of electromagnetic induction. After being powered on, it generates an alternating magnetic field. When the magnetic field covers the ferromagnetic hardware, the workpiece will generate a magnetic coupling feedback signal. The sensor can determine that the workpiece is a ferromagnetic material such as steel or cast iron by receiving a valid signal. If no feedback signal is detected, the workpiece is determined to be a non-ferromagnetic material, and the eddy current sensor is automatically switched to work. The eddy current sensor is based on the principle of eddy current effect. The probe generates an alternating magnetic field by passing an alternating current. When it approaches a non-ferromagnetic metal workpiece, an eddy current is induced on the surface of the workpiece. Eddy currents, in their reverse action, alter the probe impedance. Different metals exhibit varying conductivity and permeability, resulting in different impedance changes and ultimately, different feedback signal strengths: weak signals correspond to stainless steel, medium signals to aluminum, and high signals to copper. This allows for precise differentiation of various non-ferromagnetic metals. Wiring groove 96 provides wiring space for the sensor assembly 95 and facilitates heat dissipation. Protective plate 97 provides external protection for the sensor assembly 95, effectively preventing damage from machining debris and cutting fluid. After material detection and verification, controller 11 executes logical judgment. If the detected material does not match the system's preset machining material... When the alarm 12 is triggered, it receives an abnormal level signal from the controller 11 and simultaneously activates the audible and visual warning module. A high-frequency flashing warning light, combined with a high-decibel buzzer alarm, visually alerts the operator to the abnormality of the workpiece material. Simultaneously, the controller 11 locks the operating permissions of all actuators, forcibly stopping all subsequent processing operations. If the material inspection is qualified, the controller 11 adaptively matches the operating power of the protection component 6 according to the material type of the hardware. Following the decreasing processing difficulty of ferromagnetic materials, stainless steel, aluminum, and copper, it sequentially reduces the airflow corresponding to the hot air pipe 61 and cold air pipe 62, precisely matching the processing temperature control for different materials. To meet the requirements and achieve energy-efficient operation, the protection component 6 also includes a proportional valve, a pressure regulating valve, a flow regulating valve, and a variable frequency fan (all shown in the figure are for illustrative purposes) installed on the hot air pipe 61 and the cold air pipe 62. The equipment supplying hot air and cold air is a heating device and a cooling device with adjustable output power. The controller 11 integrates a power regulation module, which, according to the verified hardware material, controls the proportional valve, pressure regulating valve, flow regulating valve, and variable frequency fan to adjust the output power of the equipment supplying hot air and cold air, thereby regulating the gas flow rate entering the hot air pipe 61 or the cold air pipe 62 to adapt to the preheating or cooling requirements of different materials.

[0043] Working principle: After the equipment is powered on and initialized, the operator places the hardware to be processed on the support plate 85. The controller 11 drives the second hydraulic cylinder 86 to start, relying on the hydraulic transmission principle to achieve precise extension and retraction of the piston end. The two second hydraulic cylinders 86 can synchronously receive symmetrical control signals from the controller 11, driving the two clamping plates 87 to move in opposite directions at a uniform speed, completing the automatic centering, clamping and loosening of the hardware. The hydraulic drive method can ensure uniform clamping force and avoid deformation of the hardware caused by rigid clamping. The operator can move the fastener 92 in advance in the through groove 91 of the clamping plate 87 according to the specifications of the hardware, adjust the installation position of the bending plate 93, change the distance between the two sets of bending plates 93, and use the inclined outer wall of the bending plate 93 to adapt and clamp the round hardware. The vertical outer wall is adapted to clamp rectangular hardware parts, enabling adaptive fixing of hardware parts of different specifications. At the same time, the pad plate 94 provides auxiliary support for the bottom of the hardware parts, improving clamping stability. During processing, the first hydraulic cylinder 84 can be controlled to drive the support plate 85 out of the bucket 81, relying entirely on the pad plate 94 to support the hardware parts, eliminating the interference of the support plate 85 with the drilling stroke, and ensuring drilling accuracy. The controller 11 outputs control signals to drive the first linear module 21 to start running. Its built-in asynchronous motor receives signals from the controller 11, controls the number of rotations and direction of the lead screw, and drives the slide rail slider and top moving parts to make precise longitudinal linear displacement. Equipped with a closed-loop position sensor, it transmits position data in real time, realizing precise start, stop and positioning, mainly used to adjust the longitudinal position of the bucket 81.

[0044] After the hardware parts are clamped and fixed, the controller 11 triggers the sensor group 95 to power on. The inductive sensor integrated in the sensor group 95 works based on the principle of electromagnetic induction. After being powered on, it generates an alternating magnetic field. When the magnetic field covers the ferromagnetic hardware parts, the workpiece will generate a magnetic coupling feedback signal. The sensor can determine that the workpiece is a ferromagnetic material such as steel or cast iron by receiving a valid signal. If no feedback signal is detected, the workpiece is determined to be a non-ferromagnetic material, and the eddy current sensor is automatically switched to work. The eddy current sensor is based on the principle of eddy current effect. The probe generates an alternating magnetic field by passing an alternating current. When it is close to a non-ferromagnetic metal workpiece, eddy currents are induced on the surface of the workpiece. The reverse action of the eddy currents changes the impedance of the probe. The conductivity of different metal materials varies. Differences in magnetic permeability result in varying impedance changes and ultimately different feedback signal strengths: weak signals correspond to stainless steel, medium signals to aluminum, and high signals to copper, thus accurately distinguishing various non-ferromagnetic metal materials. Specifically, eddy current sensors operate based on the eddy current effect. Before actual testing, standard samples (such as standard stainless steel, standard aluminum, and standard copper blocks) with the same specifications, shape, and surface condition as the workpiece to be tested can be used to calibrate the sensor at the same detection distance and frequency, establishing a reference signal strength range for each material. During testing, the sensor group 95 compares the measured signal strength with the pre-stored reference range; for example, under the same testing conditions... Copper has the highest conductivity, so its feedback signal strength is usually in a high reference range; aluminum is next; while stainless steel has low conductivity, so its signal strength is usually in a low reference range. Based on this relative comparison logic, controller 11 assists in determining the material type of non-ferromagnetic hardware. Simultaneously, controller 11 combines the results from the inductor sensor (whether it is a ferromagnetic material) for a comprehensive logic judgment. Wiring groove 96 provides wiring space for sensor group 95 and achieves heat dissipation. Protective plate 97 provides external protection for sensor group 95, effectively preventing damage from machining debris and cutting fluid. After material detection and verification, controller 11 executes a logic judgment. If the detected material matches the system... If the preset processing material is mismatched, alarm 12 is triggered: Alarm 12 receives the abnormal level signal from controller 11 and simultaneously activates the audible and visual warning module. The high-frequency flashing warning light, combined with the high-decibel buzzer alarm, intuitively alerts the staff that the workpiece material is abnormal. At the same time, controller 11 locks the operating permissions of all actuators and forcibly stops all subsequent processing operations. If the material is qualified, controller 11 adaptively matches the operating power of protection component 6 according to the material type of the hardware. Following the decreasing processing difficulty of ferromagnetic, stainless steel, aluminum, and copper materials, it sequentially reduces the corresponding airflow of hot air pipe 61 and cold air pipe 62 to accurately match the processing temperature control requirements of different materials and achieve energy-saving and efficient operation.

[0045] Before the formal drilling process, the equipment enters the pre-treatment stage. The controller 11 outputs a level signal to control various solenoid valves to complete the state switching. Among them, the first solenoid valve 46 is an electromagnetic on-off control valve. During the preheating stage, the controller 11 controls the first solenoid valve 46 to de-energize and close, cutting off the negative pressure suction passage. It controls the second solenoid valve 63 matched with the hot air pipe 61 to be energized and opened, and the second solenoid valve 63 matched with the cold air pipe 62 to be de-energized and closed, so that the hot air passage is opened separately. The hot air equipment delivers constant temperature hot air through the hot air pipe 61. The hot air is sprayed out through the main pipe 45 and the cylinder 47. The controller 11 synchronously controls the drilling machine 24 to start and stop at low speed. The drilling machine 24 works by relying on the built-in servo motor to drive the spindle. High-speed rotation allows for precise adjustment of speed and torque. During the preheating stage, low-speed operation is controlled to drive the drill bit 25 to rotate at a uniform and slow speed, ensuring that hot air completely and without dead angles surrounds the drill bit 25, achieving uniform hot air preheating. The hot air flow acts on the filter component 5, and the airflow thrust pushes the ring block 52 to overcome the elasticity of the external coil spring of the fixed rod 51, causing the ring block 52 to separate from the fixed ring 53. At the same time, the baffle 55 optimizes the airflow force through its staggered layout structure, ensuring that the ring block 52 and the filter plate 54 can smoothly move away from the fixed ring 53, avoiding obstruction of the hot air flow and ensuring smooth hot air circulation. This helps to improve the temperature state of the drill bit 25 before and after processing and reduces the risk of damage caused by temperature difference or local overheating.

[0046] After the drill bit 25 is preheated, the equipment officially enters the drilling process. The controller 11 coordinates the movement of the multi-axis linear modules. The second linear module 22 operates on the same principle as the first linear module 21, using an asynchronous motor, lead screw and slide rail transmission, and position sensor closed-loop control. It is specifically responsible for the precise displacement of the horizontal axis, receiving position pulse signals from the controller 11 to drive the third linear module 23, the drilling machine 24, and the drill bit 25 to complete the horizontal hole position switching, realizing drilling of hardware parts in different horizontal positions. The third linear module 23 is a vertical lifting axis precision transmission module, controlled by the controller 11, to achieve high-precision vertical feed and tool lifting actions. It can control the drilling depth, feed speed, and retraction stroke of the drill bit 25 to ensure drilling accuracy. With the depth and accuracy met, the drill bit 25 achieves three-dimensional precise positioning through the multi-axis linkage of the second linear module 22 for lateral movement and the third linear module 23 for longitudinal feed, adapting to the needs of multi-hole processing of hardware parts. At the same time, the drilling machine 24 receives the processing signal from the controller 11 and switches to high-speed operation mode, driving the drill bit 25 to rotate at high speed. Relying on the high-speed rotation cutting force, it continuously drills and cuts the metal material of the hardware parts. During the processing, the cutting fluid supply equipment delivers cutting fluid through the inlet pipe 31. The operator can flexibly adjust the bending angle of the bamboo tube 32 in advance and change the spray direction of the nozzle 33 so that the cutting fluid is sprayed onto the processing contact position between the drill bit 25 and the hardware parts, so as to achieve continuous lubrication, cooling and chip removal at the processing point, and reduce drilling wear and processing burrs.

[0047] Throughout the drilling process, the cleaning component 4 and auxiliary component 7 work together to clean the drilling operation. Connecting rod 41 provides fixed support for the dome 42. The dome 42's conical structure prevents cutting fluid and debris from splashing outwards, achieving isolation and protection of the processing area. Controller 11 energizes and opens the first solenoid valve 46, connecting the main pipe 45 and the bend 44. The negative pressure suction device draws air through the pipes, creating a stable negative pressure environment inside the cylinder 47. Some of the cutting fluid sprayed obliquely downwards onto the drill bit 25 is drawn back by the upward negative pressure of the cylinder 47, allowing the cutting fluid to fully coat and wet the outside of the drill bit 25, further optimizing drilling lubrication and cooling, and improving drilling accuracy. (Specifically: the open end of the cylinder 47 and the nozzle 33 are located on opposite radial sides of the drill bit 25. The nozzle 33 sprays cutting fluid onto the contact area between the drill bit 25 and the workpiece.) The cylinder 47 forms a low-intensity negative pressure reflux zone on the other side of the drill bit 25, causing some of the atomized or splashed cutting fluid to reflux along the outer periphery of the drill bit 25, thereby prolonging the residence time of the cutting fluid on the outer periphery of the drill bit 25. This allows the cutting fluid to overcome gravity and remain on the surface of the drill bit 25, fully enveloping and wetting the outside of the rotating drill bit 25. Under the action of negative pressure suction, the sucked-up cutting fluid is sequentially drawn into the cylinder 47-bend 44-main pipe 45 and then into the negative pressure suction device. At the same time, the auxiliary pipe 71, which is fixedly supported by the side rod 43, is connected to the negative pressure suction device, so that multiple sets of suction nozzles 73 distributed in a circular array at the bottom of the annular pipe 72 generate negative pressure simultaneously. This comprehensively removes the splashed cutting fluid and fallen debris from the machining area, cleaning machining impurities without dead corners, keeping the working area clean, avoiding the accumulation of debris that affects machining accuracy, and effectively improving the overall machining efficiency.

[0048] During the negative pressure suction operation of the cleaning component 4, the filter component 5 continuously operates to intercept and protect against debris. Under normal negative pressure suction, the external coil spring of the fixing rod 51 drives the ring block 52 to adhere to the fixing ring 53, and the filter plate 54 seals the opening of the fixing ring 53, filtering the airflow inside the suction bend 44, intercepting fine metal debris generated during drilling, and preventing debris from entering the negative pressure pipeline and causing pipeline blockage and internal wear of the equipment, thus ensuring the long-term stable operation of the cleaning equipment. The baffle 55 can reduce the gas flow area of ​​the filter plate 54, effectively increasing the adsorption force of the negative pressure on the ring block 52, making the ring block 52 and the fixing ring 53 fit more tightly, preventing impurities from leaking out, and strengthening the filtration and interception effect. Under the condition of hot air preheating in the early stage and cold air cooling in the later stage, the forward airflow thrust can stably push the ring block 52 and the filter plate 54 apart, automatically releasing the sealing state, eliminating airflow resistance, ensuring smooth temperature adjustment operation, and realizing adaptive switching between filtration and ventilation conditions.

[0049] After a batch of metal parts is drilled, the controller 11 switches the equipment operating conditions, closes the first solenoid valve 46 to cut off the negative pressure pipeline, and simultaneously switches the working state of the second solenoid valve 63, closing the second solenoid valve 63 corresponding to the hot air pipe 61 and opening the second solenoid valve 63 corresponding to the cold air pipe 62, thus opening the cold air passage separately. The cold air equipment delivers low-temperature cold air through the cold air pipe 62, which is continuously sprayed onto the drill bit 25, which is in a low-speed rotating state, through the main pipe 45 and the cylinder 47. This rapidly and evenly cools the drill bit 25, which is in a high-temperature state after high-speed processing, quickly releasing the processing stress of the drill bit 25, avoiding high-temperature annealing and fatigue damage of the drill bit 25, and significantly extending the service life of the drill bit 25. The cold air operation process is similar. The positive airflow pushes the annular block 52 and filter plate 54 of the filter assembly 5 away from the fixed ring 53, ensuring smooth flow of cold air without any cooling dead zones. (To achieve the sharing of the same bend pipe 44 passage between the positive pressure hot air / cold air and the negative pressure suction mode, the pipeline switching structure is as follows:) A first solenoid valve 46 is installed on the side of the main pipe 45 near the negative pressure suction device to control the opening and closing of the negative pressure passage. A second solenoid valve 63 is installed on the hot air pipe 61 and the cold air pipe 62 respectively to control the opening and closing of the positive pressure passage; When positive pressure output is required, the first solenoid valve 46 closes and the corresponding second solenoid valve 63 opens. Hot or cold air flows through the main pipe 45 to the bend pipe 44 and will not backflow into the negative pressure suction device. When negative pressure suction is required, the two second solenoid valves 63 are closed and the first solenoid valve 46 is opened. The negative pressure suction device forms suction at the cylinder 47 through the main pipe 45 and the bend 44, and will not draw in air from the hot air pipe 61 or the cold air pipe 62. The above modes are mutually exclusive, and only one mode is active at any time. The controller 11 ensures that the first solenoid valve 46 and any of the second solenoid valves 63 do not open at the same time through interlocking logic to avoid positive and negative pressure conflicts.

[0050] After the cooling and curing operation is completed, the controller 11 controls all actuators to reset in sequence: the first linear module 21, the second linear module 22, and the third linear module 23 return to the initial reference position, the first hydraulic cylinder 84 resets to receive material, and the second hydraulic cylinder 86 resets to release material. Waste liquid and waste residue that fall during processing fall into the bottom hopper 81 (conical in shape). Relying on the guiding effect of the inclined surface inside the bottom hopper 81, the waste liquid and waste residue are automatically guided out of the slag cover 82 and finally flow into the collection tank 83 for centralized collection. The waste inside the collection tank 83 can be cleaned by hand at regular intervals to complete a single complete automated processing cycle. The equipment then stands by and waits for the next processing instruction.

[0051] The first linear module 21, the second linear module 22, and the third linear module 23 all include an asynchronous motor, a lead screw, a slide rail slider, a position sensor, and corresponding moving parts. All electrical components appearing in this application are electrically connected to the controller 11 (which integrates a processor) and 220V AC mains power. The controller 11 is a conventional and known device that can control the alarm 12, the first linear module 21, the second linear module 22, the third linear module 23, the drilling machine 24, the first solenoid valve 46, the second solenoid valve 63, the first hydraulic cylinder 84, the second hydraulic cylinder 86, and the sensor group 95. The signal interaction of each component adopts the PLC control protocol commonly used in industrial equipment, which is common knowledge to those skilled in the art and can be implemented without additional detailed description.
