Technical Field
[0001] This invention relates to the field of milling equipment technology, specifically a CNC milling machine with adaptive positioning. Background Technology
[0002] CNC milling equipment is a high-precision automated machining equipment that operates based on computer numerical control technology. Relying on a high-speed rotating milling cutter, the equipment can accurately cut on the surface and inside of the workpiece to process various grooves, curved surfaces and complex irregular structures. It has a high degree of automation and stable machining accuracy, and can be adapted to workpieces of various materials such as metal and non-metal. It is widely used in the fields of machinery manufacturing, hardware accessories, mold processing and other fields, effectively improving processing efficiency and product qualification rate. It is a core piece of equipment commonly used in modern precision machining.
[0003] However, the existing technology has the following shortcomings: In CNC milling operations, although the milling cutter head has the ability to move adaptively in the X, Y and Z axes, the anti-displacement auxiliary fixing component blocks the feed range of the cutter head, which means that the workpiece must be manually reversed after milling on one side. The resulting repeated clamping and positioning errors cause the groove symmetry to exceed the tolerance and the processing efficiency to be low. Summary of the Invention

The plate is placed on the table, and after being limited, locked and clamped, it is milled by pressing down and pneumatic pusher. Then, the pneumatic components move laterally in coordination and drive the plate to rotate and reset with the assistance of the steering motor.

[0017] In a further improvement to the present invention, the milling spindle includes an electric spindle table, an annular water curtain is provided around the electric spindle table, a tool mounting slot is provided in the center of the electric spindle table, an adaptive cooling component is installed on the electric spindle table, a tool magazine is installed next to the electric spindle table, and a tool changing component is provided below the tool magazine; an even number of water supply connectors are provided around the electric spindle table, and each of the even number of water supply connectors is connected to a tension guide tube; an even number of electrically controlled push rods are installed next to the electric spindle table, and a reversing connecting block is installed at the top of each electrically controlled push rod.
[0018] By adopting the above technical solution, the water supply connector is mainly used for the transmission of milling coolant, thereby inputting the coolant into the matching cooling component with the assistance of the stretching conduit for subsequent cold liquid output.
[0019] In a further improvement to the present invention, the adaptable cooling component includes an even number of fixed seats, each of which is equipped with a hinged swing block. A short swing liquid supply platform is installed on one of the even number of the hinged swing blocks, and a long swing liquid supply platform is installed on another even number of the hinged swing blocks. A rear-mounted shaft block is installed on the rear surface of both the short swing liquid supply platform and the long swing liquid supply platform. A hinged connecting rod is connected to the rear-mounted shaft block, and a linkage transmission rod connects the short swing liquid supply platform and the long swing liquid supply platform.
[0020] By adopting the above technical solution, the short pendulum liquid supply platform is mainly used for the output of coolant from the upper end of the milling cutter, while the long pendulum liquid supply platform is mainly used for the output of coolant from the lower end of the milling cutter.

The annular water guide box is fixed to the periphery of the electric spindle table by the suspension rods. The annular water guide box is supplied with liquid through the guide pipe, and the liquid supply flow rate is controlled by the electrically controlled valve. The electrically controlled valve is electrically connected to the control panel.
[0022] By adopting the above technical solution, the electronically controlled valve mainly controls the water output of the annular water guide box, so that the coolant is output vertically downward from the first water outlet and the second water outlet, forming a circular water curtain to prevent milling chips from splashing out.
[0023] In a further improvement to the present invention, both the short pendulum liquid supply platform and the long pendulum liquid supply platform are driven by the rear-mounted shaft block and are hinged to the hinged pendulum block.

[0024] By adopting the above technical solution, the stretching conduit is adaptively adjusted during the swing of the long and short liquid supply platforms to continuously supply coolant and avoid the situation where it breaks and cannot supply coolant.
[0025] Compared with the prior art, the present invention has the following beneficial effects; 1. This invention places the workpiece plate on a platform, where it is limited by an upper convex top block, engaged by an extension reversing assembly, and clamped by upper and lower clamping blocks. Milling is then completed with the lower pressing assembly and anti-deviation pneumatic pusher for top fixation. Subsequently, the lower pressing assembly resets, the third pneumatic pusher drives the clamping blocks to move laterally, the pneumatic rod assembly rises, and the second pneumatic pusher moves laterally. During this movement, the clamping components provide secondary clamping of the suspended plate, and with the assistance of a steering motor, the rotating carrier plate is driven to rotate, completing the automatic reversing and reset. This device achieves fully automatic reversing, completely eliminating the repetitive positioning errors caused by multiple clamping operations, effectively ensuring the symmetry of the groove meets the standards, and significantly improving processing efficiency.
[0026] 2. This invention diverts the water supply through the water supply pipe inside the milling spindle. Part of the coolant is guided into the annular water box through the tension conduit after being controlled by an electronically controlled valve. With the cooperation of the first and second water outlets, an annular water curtain is formed to isolate the splashing of debris. At the same time, the electronically controlled push rod drives the hinged connecting rod to swing the long and short pendulum liquid supply platform, which is adapted to the precise cooling of the upper and lower parts of the milling cutter. Compared with the traditional open impact cooling, it effectively avoids the rebound of debris into the cutting area, and significantly improves the machining quality. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings: Example
[0034] As attached Figure 1 To be continued Figure 6 Appendix Figure 10 As shown: This embodiment provides a CNC milling machine with adaptive positioning, including a milling machine body 1, a control panel 2 installed in front of the milling machine body 1, a pair of opening and closing doors 3 installed on the milling machine body 1, a machining cavity 4 formed inside the milling machine body 1, side windows 5 opened on both the left and right sides of the milling machine body 1, a cold liquid circulating water tank 6 installed beside the milling machine body 1, a milling spindle 41 installed in the machining cavity 4, a cross slide 43 installed in the machining cavity 4, a connecting support block 44 fixed on the cross slide 43, a machining table 45 installed on the connecting support block 44, and a cold liquid recovery guide groove 42 opened around the cross slide 43.
[0035] Furthermore, the coolant recovery guide 42 is mainly used to recover the coolant generated during the use of the milling machine body 1, which is then filtered in the coolant circulation water tank 6 and reused for the milling machine body 1.
[0036] The processing table 45 includes a fixed base 451, on which a table body 452 is mounted. An electric trigger 453 is mounted on the upper surface of the table body 452. An even number of pressing components 456 are mounted in front of the electric trigger 453. Anti-deviation pneumatic pushers 454 are installed at intervals between the pressing components 456. A side top block 455 is connected to the front of each anti-deviation pneumatic pusher 454.
[0037] Furthermore, both the electronically controlled trigger 453 and the anti-deviation air pusher 454 are supplied with air by the air pump generated by the compressor of the milling machine body 1, and the anti-deviation air pusher 454 and the pressing component 456 are staggered and arranged in a straight line.
[0038] Furthermore, the side top block 455 is mainly driven to move horizontally after being triggered by the anti-deviation pneumatic component 454, and cooperates with the upper convex top block 4525 to complete the clamping workpiece plate on both sides to prevent the plate from shifting.
[0039] The platform 452 has an alignment groove 4521, and the side walls of the alignment groove 4521 are equipped with side clips 4522. The side walls of the platform 452 are equipped with embedded rod sleeves 4523, and the embedded rod sleeves 4523 are equipped with extension reversing components 4524. The surface of the platform 452 is fixed with an upper protruding block 4525.
[0040] Furthermore, the side walls of the alignment groove 4521 are each equipped with side retaining strips 4522 for embedding into the slotted plate 45243 in front of the table, so that the workpiece plate can be kept flat after it is placed and can be accurately aligned during resetting.
[0041] Furthermore, the embedded rod sleeve 4523 installed inside the platform 452 is mainly used to assist the subsequent extension reversing assembly 4524 in extending, thereby driving the workpiece plate clamped at the end side of the extension reversing assembly 4524 to move outward synchronously.
[0042] The extended reversing assembly 4524 includes an even number of nested extension rods 45241. The ends of the even number of nested extension rods 45241 are fixed to a mounting platform 45242. A slotted front plate 45243 is fixed to the front of the mounting platform 45242. A pneumatic push rod 45244 is installed below the mounting platform 45242. A lifting frame 45245 is fixed to the body of the pneumatic push rod 45244. A second pneumatic push rod 45246 is fixed between the lifting frames 45245. A cable collection tray 45247 is installed on the top of the lifting frame 45245. A clamping reversing component 45248 is installed on the top of the second pneumatic push rod 45246.
[0043] Furthermore, the nested extension rod 45241 is used to nest into the inner rod sleeve 4523, thereby assisting in the support and stability of the mounting platform 45242 during the extension process.
[0044] Furthermore, the pneumatic push rod 45244 is mainly used to change the height of the lifting frame 45245, thereby indirectly enabling the clamping and reversing component 45248 to adapt to the workpiece plate after the height change and form clamping on both sides to complete the reversing work.
[0045] Furthermore, the second pneumatic push rod 45246 is mainly used to drive the clamping reversing component 45248 to extend forward, thereby driving the clamping reversing component 45248 to move to the middle position of the plate, and completing the 180° rotation reversal of the plate.
[0046] Among them, a pneumatic rod assembly 452421 is installed below the mounting platform 45242. An even number of grooves 452423 are opened on the surface of the mounting platform 45242. An upper clamping block 452422 and a lower clamping block 452424 are respectively installed on the pneumatic rod assembly 452421. A third pneumatic push rod 452425 of the pneumatic rod assembly 452421 is installed inside the mounting platform 45242.
[0047] Furthermore, the pneumatic rod assembly 452421 includes two sets of pneumatic rods, which are used for the installation of the upper clamping block 452422 and the lower clamping block 452424, respectively. The lower clamping block 452424 is embedded in the groove 452423 on the platform, making it parallel to the surface of the mounting bracket 45242.
[0048] Furthermore, the third pneumatic push rod 452425 mainly drives the mounting platform 45242 to move laterally after the push rod extends, which in turn moves horizontally in conjunction with the nested extension rod 45241 installed in front.
[0049] The clamping reversing component 45248 includes a support platform 452481, an annular sleeve 452482 fixed between the support platforms 452481, a steering motor 452483 mounted on the support platform 452481, a drive gear 452485 mounted on the steering motor 452483, a rotating carrier plate 452484 nested outside the drive gear 452485, and clamping members 452486 mounted on the lower ends of both ends of the rotating carrier plate 452484, with spring rod top blocks 452487 mounted on each clamping member 452486.
[0050] Furthermore, the steering motor 452483 mainly drives the drive gear 452485 to rotate, which indirectly causes the rotating carrier plate 452484 meshing with it to rotate 180° in the annular sleeve 452482 and then stop.
[0051] Furthermore, clamps 452486 are installed at both ends of the rotating carrier plate 452484, and the thickness of the plate pushes up the spring rod top block 452487 as the plate is inserted. Under the clamping cooperation of the spring rod top block 452487 and the clamps 452486, the rotation of the plate is stable.
[0052] The specific working principle is as follows: This invention opens the hinged door 3 on the main body 1 of the milling machine, revealing the post-processing chamber 4. The milled sheet metal is then mounted on the surface of the table 452 in the processing table 45 on the connecting support block 44. One side is pushed closed by the upper convex top block 4525, and the control panel 2 triggers the anti-deviation pneumatic pusher 454, which drives the side top block 455 to push forward, completing the positioning of the processed sheet metal. Then, the pressing component 456 is triggered, causing the fourth pneumatic push rod 4531 on the hinged fixing seat 4532 to extend forward, driving the connecting sleeve block 4533 to press down the fixed horizontal connecting rod 4564 with the cooperation of the fixing sleeve 4563. This causes the adjusting pressing rod 4561, along with the fixed horizontal pressing block 4562, to press down onto the center surface of the workpiece sheet metal. Meanwhile, the end side is pneumatically... The lever assembly 452421 includes a push rod that drives the lower clamping block 452424 to press down, cooperating with the upper clamping block 452422 to achieve clamping. Finally, the opening / closing door 3 is closed, and the control panel 2 triggers the milling spindle 41. According to the program settings, it cooperates with the cross slide 43 to complete the single-sided milling of the workpiece plate surface. After the single-sided milling is completed, the control panel 2 issues a control command to reset the pneumatic pusher 454 and the pressing assembly 456. Under the extension and retraction of the third pneumatic push rod 452425, the side wall of the top closing table 452 moves outward, and the front slotted clamping plate 45243 of the mounting bracket 45242 separates from the alignment groove 4521 and the side clamping strip 4522. The nested extension rod 45241 extends outward from the embedded rod sleeve 4523 to complete the installation. The mounting platform 45242 is supported by a pneumatic push rod 45244, which, together with the lifting frame 45245 and the clamping reversing component 45248, rises to a certain height and then stops. After stopping, the pneumatic rod assembly 452421 drives the upper clamping block 452422 and the lower clamping block 452424 to complete the clamping and lifting of the plate, allowing the plate to be suspended on one side after milling. During the suspension process, the second pneumatic push rod 45246 extends, controlling the bearing platform 452481 to move horizontally with the plate. At the same time, the cable collection tray 45247 releases the cable of the steering motor 452483, extending to the middle section of the plate. With the cooperation of the spring rod top block 452487, the clamping component 452486 completes the fixation of both sides of the plate. At this time, the upper clamping block 452422 and the lower clamping component 452424 are in contact with the plate. Blocks 452424 move up and down respectively, triggering the steering motor 452483. During the rotation of the drive gear 452485 and the rotating carrier plate 452484, the clamped plate rotates 180° and then stops. After stopping, the upper clamping block 452422 and the lower clamping block 452424 clamp the plate back to its initial height. Meanwhile, the third pneumatic push rod 452425 retracts, pulling the mounting platform 45242 back to reset, causing the slotted clamping plate 45243 in front of the platform to re-engage in the alignment slot 4521, completing the reset. The anti-deviation pneumatic pusher 454 is triggered again, driving the side top block 455 to secure the workpiece plate. The pressing component 456 presses down, completing the automatic reversing reset. This completely eliminates the repeated positioning error caused by multiple clamping operations and effectively ensures that the symmetry of the groove meets the standard.This significantly improved processing efficiency.

[0054] The milling spindle 41 includes an electric spindle table 411, an annular water curtain 412 is provided around the electric spindle table 411, a tool mounting slot 413 is provided in the center of the electric spindle table 411, an adaptive cooling component 414 is installed on the electric spindle table 411, a tool magazine 416 is installed next to the electric spindle table 411, and a tool changing component 415 is provided below the tool magazine 416.
[0055] Furthermore, the cooling adapter 414 is mainly set around the electric spindle table 411. During the operation of the milling cutter driven by the electric spindle table 411, it adapts to the length of different milling cutters for adaptive adjustment, so that it can always complete the cooling of the milling cutter.
[0056] Among them, an even number of water supply connectors 4111 are provided around the electric spindle table 411, and each of the even number of water supply connectors 4111 is connected to a tension conduit 4112. An even number of electrically controlled push rods 4113 are installed next to the electric spindle table 411, and each of the electrically controlled push rods 4113 has a reversing connecting block 4114 installed at the top of its body.
[0057] Furthermore, the connection between the water supply connector 4111 and the stretching conduit 4112 can be rotated, thereby assisting the stretching conduit 4112 in rotating as it extends, thus preventing the stretching conduit 4112 from twisting and breaking.
[0058] Furthermore, at least two electrically controlled push rods 4113 are provided, respectively installed on the side of the electric spindle table 411 away from the tool changer 415, so as not to delay the normal tool changing operation of the tool changer 415 in the tool magazine 416.
[0059] The annular water curtain 412 includes an electrically controlled valve 4121, a guide pipe 4122 connected to the electrically controlled valve 4121, an annular water guide box 4124 connected to the end of the guide pipe 4122, an even number of suspension rods 4123 fixed on the annular water guide box 4124, and a groove 4125 on the annular water guide box 4124. A first water outlet groove 4126 and a second water outlet groove 4127 are respectively opened in the groove 4125.
[0060] Furthermore, the electronically controlled valve 4121 is mainly used to control the supply of coolant, so that the coolant is input into the annular water guide box 4124 with the assistance of the guide pipe 4122, and is output vertically downward from the slots in the groove 4125 on the box to form an annular water curtain, which is used to prevent flying debris from splashing out.
[0061] Furthermore, the first and second water outlet grooves 4127 in the groove 4125 on the box are arranged alternately, with the first water outlet groove 4126 located on the inner circle and the second water outlet groove 4127 on the outer circle. The two ends of the second water outlet groove 4127 overlap with the first water outlet groove 4126 to avoid the formation of gaps.
[0062] The adapter cooling component 414 includes an even number of fixed seats 4141, each of which is equipped with a hinged swing block 4142. A short swing liquid supply platform 4143 is installed on one of the even number of hinged swing blocks 4142, and a long swing liquid supply platform 4145 is installed on another even number of hinged swing blocks 4142. A rear-mounted shaft block 4144 is installed on the rear surface of both the short swing liquid supply platform 4143 and the long swing liquid supply platform 4145. A hinged connecting rod 4146 is connected to the rear-mounted shaft block 4144, and a linkage transmission rod 4147 is connected between the short swing liquid supply platform 4143 and the long swing liquid supply platform 4145.
[0063] Furthermore, at least four articulated swing blocks 4142 are evenly distributed in a ring and are all fixed on the same number of fixed seats 4141. The articulated swing blocks 4142 assist the long swing liquid supply platform 4145 or the short swing liquid supply platform 4143 to achieve articulated swing and complete different height adjustments.
[0064] Furthermore, the short pendulum liquid supply platform 4143 and the long pendulum liquid supply platform 4145 have the same appearance but different lengths. Both form a channel output through the built-in groove under the coolant supply of the stretching conduit 4112. Then, with the assistance of the long and short pendulum liquid supply platforms, the upper and lower ends of the milling cutter are cooled.
[0065] Furthermore, the short pendulum liquid supply platform 4143 and the long pendulum liquid supply platform 4145 form a group, and there are two types in total. In each group, a rear-mounted shaft block 4144 is fixed behind a liquid supply platform. The rear-mounted shaft block 4144, together with the hinged connecting rod 4146 and the electrically controlled push rod 4113, realizes the angle and position adjustment.
[0066] The specific working principle is as follows: This invention utilizes the milling machine body 1, under the program control of the control panel 2, to control the cross slide 43 and the electric spindle table 411 to achieve milling of the workpiece plate. During the milling process, the coolant circulating water tank 6 supplies water to the annular water curtain 412 and the matching cooling component 414 on the electric spindle table 411. The electronically controlled valve 4121 controls the coolant volume, which, with the assistance of the guide pipe 4122, is input into the annular water guide box 4124 fixed by the suspension rod 4123. The coolant is then output from the first water outlet 4126 and the second water outlet 4127 on the groove 4125 of the box, forming an annular water curtain that surrounds the milling cutter on the electric spindle table 411. The electronically controlled push rod 4113, controlled by the control panel 2, extends or retracts, driving the reversing connecting block 4114 to adjust the orientation of the hinged connecting rod 4146, indirectly driving... The short swing liquid supply platform 4143 and the long swing liquid supply platform 4145, fixed in front of the rear-mounted shaft block 4144, swing and adjust to point to the upper-middle and lower-middle positions of the end mill, respectively. With the continuous output of coolant from the channel in the platform, the end mill is cooled. The coolant output from the annular water guide box 4124 and the short swing liquid supply platform 4143 and the long swing liquid supply platform 4145 is returned to the coolant circulating water tank 6 through the coolant recovery guide channel 42, filtered, and recycled. Finally, through the cooperation of the annular water guide box 4124 and the short swing liquid supply platform 4143 and the long swing liquid supply platform 4145, compared with the traditional open impact cooling, it effectively avoids the rebound of debris to the cutting area. In addition, the electric control push rod 4113 drives the hinged connecting rod 4146 to swing the long and short swing liquid supply platforms, which accurately cools the upper and lower parts of the end mill, significantly improving the machining quality.

It is clamped at the end side by the upper clamping block 452422 and the lower clamping block 452424. At the same time, the lower pressing component 456 and the anti-deviation air pusher 454 respectively press the middle part and the other side of the plate to complete the pre-milling fixation. S2, Milling Reset: After single-sided milling is completed, the lower pressure assembly 456 resets and releases the pressure in the middle. The third pneumatic push rod 452425 extends, driving the upper and lower clamping blocks and the plate to move horizontally synchronously. Then, the pneumatic rod assembly 452421 drives the upper and lower clamping blocks to rise, suspending the plate in the air. S3. Transfer and connection: The second pneumatic push rod 45246 assists in the horizontal movement of the clamping and reversing component 45248, and during the movement, the clamping component 452486 forms a secondary clamping on both sides of the suspended plate to ensure stable transfer.
[0068] S4. Rotation and reversal: With the assistance of the steering motor 452483, the rotating carrier plate 452484 is driven to rotate, realizing the plate turning 180° and completing the automatic reversal action; S5. Reset CNC: The plate after reversal is reset to the surface of the table 452, and then repositioned and locked by the anti-deviation pneumatic pusher 454 and the pressing assembly 456 for milling on the other side. S6. Results achieved: The fully automated reversing process eliminates repeated positioning errors, effectively ensures the symmetry of the tank meets the standards, and significantly improves processing efficiency.
