Description

Technical Field

[0001] This application relates to the technical field of aluminum profile punching and grinding, and in particular to an integrated processing equipment for aluminum profile punching and grinding. Background Technology

[0002] To meet the diverse connection, assembly, and functional requirements of aluminum profiles, it is usually necessary to punch blind holes of different depths on the aluminum profiles to hide screws or locating pins of different depths. Different depths are directly related to structural strength, weight distribution, and appearance requirements, and are key to achieving lightweight design and improving assembly reliability. After punching, in order to ensure the quality of the holes, it is usually necessary to grind and chamfer the holes to ensure the quality of the holes on the aluminum profiles.

[0003] Existing technologies generally employ a segmented, equipment-based approach for punching and grinding aluminum profiles. First, the aluminum profile is positioned and clamped onto a dedicated punching machine. The required holes are then punched or drilled using a die. After punching, the machine must be stopped and the profile manually disassembled and moved to a grinding machine at another workstation. After repositioning and clamping, an angle grinder, chamfering drill, or a dedicated deburring tool is used to grind and chamfer the holes one by one.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Firstly, separating the punching and grinding of aluminum profiles severely restricts production efficiency. Since each process requires disassembling, transporting, and re-clamping the workpiece, and repeated calibration of hole positions and grinding reference surfaces is necessary during clamping, it not only consumes a lot of time and leads to low equipment utilization, but also easily causes workpiece collisions, deformation, or positioning errors during transport. Frequent shutdowns and restarts further lengthen the production cycle. The entire process relies on multiple manual handling, repeated clamping, and equipment switching, making it difficult for the production line to achieve continuous operation. Especially in small-batch, multi-variety production, the changeover and debugging time accounts for too high a proportion. Therefore, improvements are proposed. Summary of the Invention

[0005] To address the aforementioned problems, this application provides an integrated processing equipment for punching and grinding aluminum profiles.

[0006] The integrated processing equipment for punching and grinding aluminum profiles provided in this application adopts the following technical solution: An integrated processing equipment for punching and grinding aluminum profiles includes a support frame, a punching assembly, a grinding assembly, a cooling assembly, a marking assembly, a clamping component, and a translation component for punching, grinding, cooling, marking, clamping, and translation of aluminum profiles. The punching assembly includes a support block slidably mounted on a support frame, a drill bit rotatably mounted on the support block, a sliding component for lifting and lowering the support block, and a driving component for rotating the drill bit. The grinding assembly includes a limiting frame movably mounted on a support frame, a grinding ring movably mounted on a drill bit, two grinding blades connected to the grinding ring, a tensioning component for adjusting the tightness of the grinding ring, and an adjusting component for adjusting the height of the grinding ring. The grinding ring can be rotated by a driving component, and the limiting frame is movably fitted with the grinding ring. The cooling assembly includes a spray head fixed on a support block, three cooling pipes fixed on a support frame, a water storage device for drawing coolant into the spray head, a flow rate adjustment device for adjusting the flow rate of coolant in the spray head, and a switching device for switching the three cooling pipes on and off. The marking assembly includes a rotating disk rotatably mounted on a grinding ring, three markers connected to the rotating disk, and a rotating component and a positioning component for rotating and positioning the rotating disk. The switching component, rotating component, and positioning component are all automatically driven by an adjusting component. The three markers are red, black, and white markers. The red marker can mark shallow blind holes, the black marker can mark medium blind holes, and the white marker can mark deep blind holes.

[0007] By adopting the above technical solution, the existing technology usually uses the same coolant for punching blind holes of different depths. This is not convenient to adjust according to the different depths of the blind holes in the aluminum profiles being processed, which will cause a series of problems. For shallow blind holes, if a high-concentration, strong cooling coolant designed for deep holes is used, excessive cooling will cause a sudden drop in local temperature, causing thermal stress cracks in the aluminum material, affecting processing quality and increasing costs. At the same time, excessive lubrication may cause chips to adhere to the hole wall, increasing the difficulty of subsequent cleaning. When processing deep blind holes, ordinary coolant cannot penetrate into the cutting zone and cannot effectively remove a large amount of heat, causing the drill temperature to rise sharply, accelerating drill wear or even chipping, shortening its service life. Moreover, heat accumulation can soften the aluminum material, causing problems such as hole wall deformation and out-of-tolerance dimensional accuracy. In addition, the chip removal situation is different when processing blind holes of different depths. The chip removal performance of the same coolant cannot be adapted to all working conditions, which can easily cause chip blockage, affecting processing efficiency and surface quality. Therefore, not switching the coolant according to the depth of the blind hole will reduce processing quality and efficiency and increase production costs. In existing technologies, when drilling continuously into aluminum alloys, coolant is used for cooling. The amount of coolant is usually kept constant, which brings many problems. When the drill bit temperature is low, excessive coolant not only wastes resources but may also cause local shrinkage of the aluminum alloy due to overcooling, affecting the dimensional accuracy and surface quality of the hole. When the drill bit temperature rises sharply after prolonged operation, the fixed amount of coolant cannot remove a large amount of heat in time, leading to increased thermal stress on the drill bit, accelerated wear, and even chipping, shortening its service life. At the same time, heat accumulation can also soften the aluminum alloy material, causing hole wall deformation, reducing machining accuracy, increasing scrap rate, and increasing production costs. In existing technologies, after punching holes in aluminum profiles, subsequent processing such as grinding or tapping is usually required. Different tools are typically used depending on the depth of the blind holes in the aluminum profile. During processing, especially when dealing with blind holes that look similar but have different depths, it is difficult for workers to directly and quickly distinguish their depths with the naked eye. They need to consult complex drawings or use a depth gauge to measure each hole for confirmation, which affects the subsequent hole processing results. Moreover, if workers make incorrect judgments and use the wrong tools, it will lead to incorrect hole depth processing, resulting in the scrapping of the entire aluminum profile and causing cost losses.

[0008] The punching assembly allows for punching holes in aluminum profiles, while the grinding assembly grinds and chamfers the holes. The grinding blade height can be adjusted according to the hole depth, enabling the drill bit to process blind holes of varying depths while simultaneously grinding and chamfering the openings of these holes, thus expanding the processing range of the drill bit and grinding blade. The cooling assembly cools the drill bit, grinding blade, and aluminum profile during punching and grinding. The amount of coolant sprayed can be controlled based on the continuous processing temperature of the drill bit, ensuring effective cooling of the aluminum profile by the drill bit and grinding blade, saving on coolant usage costs. Furthermore, the type of coolant can be switched according to the punching depth of the aluminum profile to improve the punching effect of blind holes at different depths, ensuring the quality of punching blind holes of varying depths on the aluminum profile.

[0009] Optionally, the sliding member includes a threaded rod rotatably mounted on a support frame and a motor fixed on the support frame. The support block is threadedly connected to the threaded rod, and the threaded rod is fixedly connected to the output end of the motor.

[0010] By adopting the above technical solution, the sliding component can drive the drill bit and grinding blade to move up and down, so as to cooperate with the drive component to punch holes and grind the holes in the aluminum profile. The motor can drive the threaded rod to rotate, which can sequentially drive the support block, drill bit, grinding ring, two grinding blades and water spray head to move up and down, so as to punch holes and grind the holes in the aluminum profile.

[0011] Optionally, the driving component includes a drive motor fixed on the support block, the drill bit is connected to the output end of the drive motor, the grinding ring is provided with a chip removal hole, and the drill bit is slidably connected to the chip removal hole.

[0012] By adopting the above technical solution, the driving component can drive the drill bit and two grinding blades to work, so as to punch holes in the aluminum profile and grind the hole openings. The driving motor can drive the drill bit, grinding ring and two grinding blades to rotate in sequence, so that the drill bit and grinding blades are in working condition. With the cooperation of the sliding component, the aluminum profile can be punched and the hole openings can be ground.

[0013] Optionally, the adjusting component includes a movable frame movably mounted on the support frame, an electric telescopic rod fixed on the movable frame, a movable block fixed on the limiting frame, and an electric push rod fixed on the support frame. The movable frame is fixedly connected to the output end of the electric push rod, the movable block is fixedly connected to the output end of the electric telescopic rod, and the limiting frame is provided with a U-shaped groove. The grinding ring is movably engaged with the U-shaped groove.

[0014] By adopting the above technical solution, the height of the grinding ring on the drill bit and grinding blade can be adjusted by the adjusting component to facilitate grinding and chamfering of holes of different depths. The electric telescopic rod can sequentially drive the movable block, the limit frame, and the bolter to move, so that the limit frame can engage with the grinding ring and the bolter can engage with the loosening bolt. The electric push rod can sequentially drive the movable frame, the movable rack, the electric telescopic rod, the movable block, the limit frame, and the bolter to move up and down, so that the limit frame can drive the grinding ring and the grinding blade to move up and down, and the height of the grinding blade can be adjusted.

[0015] Optionally, the tightening component includes a bolter fixed to the movable block and a bolt hole and a tightening bolt provided on the grinding ring. The tightening bolt is threadedly connected to the bolt hole, and the tightening bolt is movably engaged with the output end of the bolter.

[0016] By adopting the above technical solution, the grinding ring can be tightened or loosened by the tightening and loosening component, so as to facilitate the disassembly and assembly of the grinding ring and the drill bit. Driven by the electric telescopic rod, the bolter can be engaged with the tightening and loosening bolt. The bolter can drive the tightening and loosening bolt to rotate, thereby controlling the tightness or looseness of the grinding ring. The electric push rod can smoothly drive the grinding ring and grinding blade to rise and fall, and at the same time, the drill bit and the grinding ring can be stably connected together.

[0017] Optionally, the water storage device includes a water pump fixed on a support frame, a connecting hose connected to a spray nozzle, and water tanks respectively connected to three cooling pipes. The three water tanks are a low-viscosity liquid tank, a semi-synthetic liquid tank, and an extreme pressure emulsion tank. All three cooling pipes are connected to a water pumping pipe. The water pumping pipe is connected to the water inlet of the water pump, and the connecting hose is connected to the water outlet of the water pump. The adjusting component includes a solenoid valve fixed to the connecting hose and a temperature sensor fixed to the support block, wherein the temperature sensor is electrically connected to the solenoid valve.

[0018] By adopting the above technical solution, the water storage device can spray coolant on the aluminum profile during punching and grinding to cool the drill bit and aluminum profile. The water pump can sequentially pass the coolant in the water tank through the cooling pipe, the water pumping pipe, the connecting hose and the water spray head to spray the coolant on the drill bit, the grinding tool and the aluminum profile for cooling treatment. The amount of coolant sprayed can be controlled according to the operating temperature of the drill bit by adjusting the flow meter. The temperature sensor can detect the current heat of the drill bit, and then the solenoid valve can adjust the size of its flow port to control the amount of coolant sprayed. The higher the temperature of the drill bit, the more coolant is sprayed, and vice versa.

[0019] Optionally, the rotating component includes a fixed gear fixed on the rotating disk, a fixed rack disposed on the limiting frame, a support bar fixed on the support frame, a first T-slot disposed on the support block, a second T-slot disposed on the support bar, and a sliding groove disposed on the limiting frame. The first T-slot, the second T-slot, and the sliding groove are all slidably connected to the fixed rack, the fixed rack is movably meshed with the fixed gear, and the first T-slot and the second T-slot are movably connected.

[0020] By adopting the above technical solution, the outer side of the punched hole in the aluminum profile can be easily marked with a marker of a specified color according to the depth of the hole, using the rotating component. When the adjusting component drives the limiting frame to move the grinding ring, rotating disk, fixed gear, and three markers up and down, the fixed gear meshes with the fixed rack, so the fixed gear can rotate during movement, thereby adjusting the position of the three markers. When the hole processed on the aluminum profile is a shallow blind hole, the red marker can be adjusted to mark the shallow blind hole; when the hole processed on the aluminum profile is a medium blind hole, the black marker can be adjusted to mark the medium blind hole; and when the hole processed on the aluminum profile is a deep blind hole, the white marker can be adjusted to mark the medium blind hole, so that subsequent workers can quickly confirm the depth of the blind hole and perform corresponding processing.

[0021] Optionally, the switching component includes control valves fixed to three cooling pipes, movable gears and torsion springs fixed to the three control valves, and a movable rack fixed to a movable frame. The three movable gears are all movably meshed with the movable rack, and the three movable gears are respectively fixedly connected to the three torsion springs.

[0022] By adopting the above technical solution, the type of coolant spray can be switched according to the depth of the punching of the aluminum profile by means of the switching component and the adjusting component. When the electric push rod drives the movable rack to move up and down, it can mesh with three movable gears in sequence and drive them to rotate. When the movable gears rotate, the torsion spring is in a compressed state. When the movable rack meshes with the designated movable gear, the corresponding control valve can be opened, so that the coolant in the designated water tank can be drawn into the spray head through the corresponding cooling pipe when the water pump is driven. At the same time, when the movable rack separates from the movable gear, the movable gear loses its limit position, and the restoring elasticity of the torsion spring can automatically drive the movable gear to rotate, which can automatically drive the control valve to close, thereby allowing the water storage device to draw the designated type of coolant to cool the aluminum profile.

[0023] Optionally, the translation component includes a worktable movably mounted on a support frame, a spiral rod rotatably mounted on the support frame, and a servo motor fixed to the support frame. The worktable is threadedly connected to the spiral rod, and the spiral rod is fixedly connected to the output end of the servo motor.

[0024] By adopting the above technical solution, the aluminum profile can be moved by the translation component, so that the drill bit and grinding tool can punch and grind multiple parts of the aluminum profile. The servo motor can drive the spiral rod to rotate, which can sequentially move the worktable and aluminum profile, and the position of the aluminum profile can be adjusted. This allows the drill bit and grinding tool to punch and grind multiple parts of the aluminum profile, thus expanding the processing range of the aluminum profile.

[0025] Optionally, the positioning component includes a rolling block fixed on the rotating disk, two sets of connecting springs fixed on the grinding ring, limit blocks respectively fixed on the two sets of connecting springs, and multiple limit grooves provided on the rolling block. The multiple limit grooves are movably engaged with the two sets of limit blocks, and the rolling block is rotatably connected to the grinding ring.

[0026] By adopting the above technical solution, the three markers can be positioned by the positioning component to prevent the markers from rotating during marking. When the rotating component drives the rotating disk to rotate, it can drive the rolling block to rotate and compress the connecting spring. When the rolling block rotates to the designated position, the elastic force of the two sets of connecting springs can drive the two sets of limit blocks to push, so that the two sets of limit blocks can be pushed into multiple limit holes, thereby locking and positioning the rolling block, rotating disk, fixed gear and three markers.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. Place the aluminum profile on the workbench and clamp it in place to ensure the quality of punching and grinding. The drive unit and sliding unit can punch holes in the aluminum profile. When the drill bit reaches the specified depth inside the aluminum profile, the two grinding blades will fit against the outer surface of the hole. As the two grinding blades rotate, they can grind and chamfer the outer surface of the hole. This process can grind and chamfer the holes in the aluminum profile during the punching process, achieving the goal of punching and grinding the aluminum profile in one step. The hole opening can be ground immediately after punching the aluminum profile, improving the efficiency of aluminum profile processing and enabling continuous operation that is difficult to achieve on a production line. 2. During the punching process of aluminum profiles, the water reservoir can spray coolant onto the drill bit, grinding blade, and aluminum profile. This cools the drill bit, grinding blade, and aluminum profile during punching and grinding, preventing them from overheating and affecting the punching and grinding effect and quality. The translation component can adjust the position of the aluminum profile, allowing the drill bit and grinding blade to punch and grind multiple points on the aluminum profile, thus expanding the processing range. When the drill bit is continuously punching multiple points on the aluminum profile, the adjusting component can detect the heat of the drill bit and control the amount of coolant sprayed based on the drill bit temperature. The higher the drill bit temperature, the greater the amount of coolant sprayed, ensuring the cooling speed of the drill bit and aluminum profile. Conversely, the lower the drill bit temperature, the less coolant sprayed, avoiding coolant waste and ensuring the processing quality of the aluminum profile. The amount of coolant sprayed can also be controlled based on the temperature generated by continuous drilling, ensuring the effectiveness of continuous drilling on the aluminum profile. 3. When the position of the grinding ring on the drill bit needs adjustment, the tensioning device, in conjunction with the adjusting device, can adjust the height of the grinding ring and grinding cutter on the drill bit. This also ensures a stable connection between the grinding ring and the drill bit, preventing wobbling when the grinding cutter is used to chamfer holes in the aluminum profile. This guarantees the effectiveness of the grinding cutter in chamfering the aluminum profile holes. The adjusting device allows for adjusting the height of the grinding ring and grinding cutter according to the required hole depth on the aluminum profile, facilitating chamfering of holes at different depths. Furthermore, a specified type of coolant can be switched according to the hole depth on the aluminum profile to maintain the coolant level between the drill bit and the aluminum profile. Cooling ensures effective punching of holes of varying depths on the aluminum profile. When punching shallower holes, the grinding ring can be moved to a lower position on the drill bit, and a low-viscosity emulsion can be used to cool the drill bit and the aluminum profile. When punching holes of moderate depth, the grinding ring can be moved to a middle position on the drill bit, and a semi-synthetic cutting fluid can be used to cool the drill bit and the aluminum profile. When punching deeper holes, the grinding ring can be moved to a higher position on the drill bit, and an extreme pressure emulsion can be used to cool the drill bit and the aluminum profile, ensuring effective cooling of different blind holes on the aluminum profile.

[0028] 4. The rotating, adjusting, and positioning components allow for the adjustment of the positions of the three markers. This allows for marking the outer edges of the holes in the aluminum profile after grinding. The markers can be switched to the specified colors based on the hole depth. For shallow blind holes, the red marker can be used to draw a circle on the outer edge. For medium-sized blind holes, the black marker can be used. For deep blind holes, the white marker can be used. This facilitates quick confirmation of the hole depth for subsequent processing. Attached Figure Description

The motor 9, drive motor 10, electric push rod 11, electric telescopic rod 13, bolter 15, water pump 20, solenoid valve 31, temperature sensor 32, position sensor, sensing component, servo motor 27, and two electric lifting rods 29 are all electrically connected to the intelligent controller. The intelligent controller can control the timed drive of the motor 9, drive motor 10, electric push rod 11, electric telescopic rod 13, bolter 15, water pump 20, solenoid valve 31, temperature sensor 32, position sensor, sensing component, servo motor 27, and two electric lifting rods 29.

[0045] When drilling blind holes of different depths, different coolants are required for drill bit 4. This is mainly because heat dissipation requirements, lubrication effects, and chip removal difficulty vary significantly with hole depth. For shallow blind holes in aluminum alloys, a low-viscosity emulsion should be used because thin aluminum has high thermal conductivity but low strength. High-speed punching can easily lead to localized overheating, causing material softening, deformation, or even tearing. The emulsion, a mixture of emulsified oil and water, combines cooling and lubrication properties, quickly removing heat and reducing friction between the die and material, preventing die sticking. For medium-thickness blind holes in aluminum alloys, a semi-synthetic cutting fluid should be used because punching medium-thickness aluminum requires a balance between cooling and lubrication. The semi-synthetic fluid contains a small amount of mineral oil and additives, which can pass through water-based systems... The components rapidly dissipate heat, preventing the material from overheating and softening. The oily components also provide lubrication, reducing mold wear and burr formation, and ensuring a smooth hole wall. Extreme pressure emulsions should be used for punching thick blind holes in aluminum alloys because the cutting force and heat generation during punching of thick aluminum can easily lead to a rapid rise in mold temperature. Extreme pressure emulsions, with added sulfur and chlorine, can form a chemical lubricating film under high temperature and pressure, significantly reducing the coefficient of friction and preventing aluminum sticking and chipping of the mold. Therefore, when machining shallow blind holes, drill bit 4 requires cooling with a low-viscosity emulsion; when machining medium blind holes, it requires cooling with a semi-synthetic cutting fluid; and when machining thick blind holes, it requires cooling with an extreme pressure emulsion.

[0046] The implementation principle of the integrated processing equipment for punching and grinding aluminum profiles in this application is as follows: (1) Place the aluminum profile 2 to be punched on the workbench 3. Drive the two movable clamps 30 to move relative to each other and fit with the aluminum profile 2 through the two electric lifting rods 29. This can clamp and fix the aluminum profile 2, preventing the aluminum profile 2 from shaking or shifting during punching and grinding, and ensuring the punching and grinding effect of the aluminum profile 2. (2) The drive motor 10 can sequentially drive the drill bit 4, grinding ring 5, two grinding blades 6, rotating disk 34 and three markers 36 to rotate, so that the drill bit 4 and grinding blades 6 are in working condition. The motor 9 can drive the threaded rod 8 to rotate, which can sequentially drive the support block 7, drill bit 4, grinding ring 5, two grinding blades 6, rotating disk 34, three markers 36 and water spray head 18 to move up and down. Then, when the drill bit 4 rotates, it can punch holes in the aluminum profile 2. When the drill bit 4 reaches the specified depth inside the aluminum profile 2, the two grinding blades The two grinding blades 6 will fit against the outer surface of the hole, and when they rotate, they can grind and chamfer the outer surface of the hole. This can be done during the punching process of the aluminum profile 2, achieving the purpose of punching and grinding the aluminum profile 2 in one step. At the same time, when the two grinding blades 6 move downward and finish grinding the hole of the aluminum profile 2, the marker pen 36 will fit against the edge of the hole of the aluminum profile 2. As the marker pen 36 rotates, it can draw a circle on the edge of the hole of the aluminum profile 2 for marking, so that the workers can quickly distinguish the holes on the aluminum profile 2 when processing them later. (3) During the punching process of aluminum profile 2, the coolant in the water tank can be sequentially passed through the cooling pipe 22, the water pump 21, the connecting hose 19 and the spray head 18 by the water pump 20, and then the coolant can be sprayed onto the drill bit 4, the grinding knife 6 and the aluminum profile 2. During the punching and grinding process of aluminum profile 2, the drill bit 4, the grinding knife 6 and the aluminum profile 2 can be cooled to avoid the drill bit 4, the grinding knife 6 and the aluminum profile 2 being affected by the high temperature, thus affecting the punching and grinding effect and quality. (4) The servo motor 27 can drive the screw rod 28 to rotate, which can sequentially drive the worktable 3 and the aluminum profile 2 to move horizontally, and can adjust the position of the aluminum profile 2. The drill bit 4 and the grinding tool 6 can punch and grind multiple parts of the aluminum profile 2, which can enhance the processing range of the aluminum profile 2. (5) When the drill bit 4 continuously punches holes in multiple places of the aluminum profile 2, the temperature of the drill bit 4 will gradually rise. In order to ensure the processing quality of the aluminum profile 2, it is necessary to adjust the amount of coolant sprayed. When the drill bit 4 drives to dissipate heat, the temperature sensor 32 can detect the current heat of the drill bit 4. The temperature sensor 32 will transmit the signal to the solenoid valve 31 to adjust the size of its flow port, thereby controlling the flow rate of the coolant sprayed by the spray head 18. The higher the temperature of the drill bit 4, the greater the amount of coolant sprayed, which can ensure the cooling speed of the drill bit 4 and the aluminum profile 2. Conversely, the lower the temperature of the drill bit 4, the less coolant sprayed, which can avoid the waste of coolant. The amount of coolant sprayed can be controlled according to the temperature of the drill bit 4. (6) When it is necessary to adjust the position of the grinding ring 5 on the drill bit 4, the drill bit 4 can be moved to the starting height by the drive of the motor 9, so that the first T-slot corresponds to the second T-slot. Then, the electric telescopic rod 13 can sequentially drive the movable block 14, the limit frame 16, the bolter 15 and the fixed rack 33 to move horizontally, and move the fixed rack 33 to the first T-slot for limiting. This allows the limit frame 16 to engage with the grinding ring 5, the bolter 15 to engage with the loosening bolt 17, and the fixed rack 33 to mesh with the fixed gear 35. The bolter 15 can drive the loosening bolt 17 to rotate, which can loosen the grinding ring 5. Then, the electric push rod 11 can sequentially drive the movable frame 12, the movable rack 26, the electric telescopic rod 13, the movable block 14, the limit frame 16 and the bolter 15 to move up and down, which can limit the movement of the grinding ring 5. The frame 16 drives the grinding ring 5 and the grinding blade 6 to move up and down, which can adjust the height of the grinding blade 6 on the drill bit 4. After the grinding blade 6 moves to the required height, the bolt 15 drives the tightening bolt 17 to rotate again, which can re-connect the grinding ring 5 and the drill bit 4 stably, avoiding the phenomenon of the grinding blade 6 shaking when grinding and chamfering the holes of the aluminum profile plate 2, and ensuring the effect of grinding and chamfering the holes of the aluminum profile plate 2. Then, the electric telescopic rod 13 drives the limit frame 16 and the bolt 15 to move, so that the limit frame 16 separates from the chamfering ring and the bolt 15 separates from the tightening bolt 17, and moves the fixed rack 33 into the second T-slot, so that the fixed rack 33 separates from the fixed gear 35, and avoids the drill bit 4 and the grinding blade 6 being interfered with by the limit frame 16 and the bolt 15 when punching and grinding the aluminum profile plate 2. (7) When the movable rack 26 moves up and down, it can mesh with three movable gears 24 in sequence and rotate. When the movable gears 24 rotate, the torsion spring 25 is compressed. When the movable rack 26 meshes with the designated movable gear 24, the corresponding control valve 23 can be opened, so that when the water pump 20 is driven, the coolant in the designated water tank will be drawn into the spray head through the corresponding cooling pipe 22. At the same time, when the movable rack 26 separates from the movable gear 24, because the movable gear 24 loses its limit, the restoring elasticity of the torsion spring 25 can automatically The rotating gear 24 automatically drives the control valve 23 to close, allowing the rotating rack 26 to open only one designated cooling pipe 22 at a time when it rises and falls. Based on the above principle, the height of the grinding ring 5 and the grinding blade 6 can be adjusted according to the required hole depth on the aluminum profile 2, so that the grinding blade 6 can grind and chamfer holes of different depths on the aluminum profile 2. At the same time, the specified type of coolant can be switched to cool the drill bit 4 and the aluminum profile 2 according to the hole depth, which can ensure the effect of punching holes of different depths on the aluminum profile 2. (8) When it is necessary to drill a shallow hole on the aluminum profile 2, the grinding ring 5 can be moved to a lower position on the drill bit 4, and the movable rack 26 will mesh with the movable gear 24 located below, opening the lower cooling pipe 22, thereby drilling a shallow hole on the aluminum profile 2. The low viscosity emulsion in the low viscosity liquid tank can be used for cooling. When it is necessary to drill a hole of moderate depth on the aluminum profile 2, the grinding ring 5 can be moved to the middle position on the drill bit 4, and the movable rack 26 will mesh with the movable gear 24 located in the middle. When the moving gear 24 meshes, the intermediate cooling pipe 22 is opened, and a hole of appropriate depth is punched in the aluminum profile 2. The semi-synthetic cutting fluid in the semi-synthetic liquid tank can be used for cooling. When a hole of greater depth needs to be punched in the aluminum profile 2, the grinding ring 5 can be moved to a higher position on the drill bit 4. At the same time, the movable rack 26 will mesh with the movable gear 24 located above, and the upper cooling pipe 22 will be opened, and a hole of greater depth will be punched in the aluminum profile 2. The extreme pressure emulsion in the extreme pressure emulsion tank can be used for cooling. (9) When the limit frame 16 drives the grinding ring 5, the rotating disk 34, the fixed gear 35 and the three markers 36 to move up and down, the fixed gear 35 meshes with the fixed rack 33, so the fixed gear 35 can rotate when it moves, and the position of the three markers 36 can be adjusted so that the markers of the specified color are flush with the drill bit 4 and vertically downward. The specified markers 36 can be adjusted to mark the depth of the blind hole to be punched on the aluminum profile 2. When the hole processed on the aluminum profile 2 is a shallow blind hole, the red marker can be adjusted to draw a circle mark on the outer edge of the shallow blind hole. When the hole processed on the aluminum profile 2 is a medium blind hole, the black marker can be adjusted to draw a circle mark on the outer edge of the medium blind hole. When the hole processed on the aluminum profile 2 is a deep blind hole, the white marker can be adjusted to draw a circle mark on the outer edge of the medium blind hole, so that the subsequent workers can quickly confirm the depth of the blind hole and carry out the corresponding processing. (10) When the rotating disk 34 rotates, it can drive the rolling block 37 to rotate. The rotation of the rolling block 37 can squeeze the limiting block 39, causing the connecting spring 38 to be compressed. When the rolling block 37 rotates to the designated position, the elastic force of the two sets of connecting springs 38 can drive the two sets of limiting blocks 39 to push. The two sets of limiting blocks 39 can be pushed into multiple limiting holes, thereby locking and positioning the rolling block 37, the rotating disk 34, the fixed gear 35 and the three markers 36, preventing the three markers 36 from rotating due to the thrust of the rotating markers 36, so as to ensure the marking effect of the markers 36 on the aluminum profile plate 2.

[0047] Compared with existing technologies, aluminum profile punching and grinding can be performed simultaneously. After punching, the hole opening can be ground immediately, improving the efficiency of aluminum profile processing and enabling continuous operation that is difficult to achieve on a production line. At the same time, coolant can be sprayed to cool the metal during the punching and grinding of the aluminum profile. The specified coolant can be switched according to the punching depth of drill bit 4 to cool both drill bit 4 and aluminum alloy, ensuring the cooling and marking effect of different blind holes in aluminum alloy. Furthermore, the amount of coolant sprayed can be controlled according to the temperature generated by continuous processing of drill bit 4, which can ensure the use cost of coolant while ensuring the effect of continuous processing of aluminum profile by drill bit 4.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
