[0002] A milling cutter is a tool used to smooth the surface of an object. It is generally used for metal milling, but can also be used for smoothing other surfaces, such as window frame smoothing. Aluminum alloy doors and windows are usually made of four aluminum alloy profiles welded end to end. The end face of the aluminum alloy is the key part of the splicing, and its processing accuracy is high, so milling is required.

[0003] According to a disclosed aluminum alloy door and window processing and milling device (Announcement No.: CN220216844U), in the above application, the rotating shaft is driven by the output shaft of the driving motor to rotate, and then the two milling cutters on the rotating shaft can simultaneously mill the two sides of the aluminum alloy, thereby improving the milling efficiency.

[0004] However, in actual use of the above-mentioned equipment, since the accessories of aluminum alloy doors and windows themselves have a certain length, and only one end of them is usually clamped during the milling device processing, when encountering metal door and window accessories of shorter length, the top of the accessory cannot directly contact the inner bottom of the fixture inside the fixture, which makes the end of the accessory away from the fixed end susceptible to the risk of deflection and distorting when being processed by the milling cutter, thereby reducing the processing quality of aluminum alloy door and window accessories.

[0016] Compared with the prior art, the present invention provides an aluminum alloy door and window processing and milling device, which has the following beneficial effects:

[0017] 1. The aluminum alloy door and window processing and milling device is provided with a clamping assembly, which cooperates with a latch and a transmission cylinder, so that the clamping plate can adapt to aluminum alloy door and window accessories of different lengths by adjusting the position of the abutment plate after clamping and positioning the aluminum alloy door and window accessories, thereby ensuring that the ends of the aluminum alloy door and window accessories will not be deflected or skewed during the milling process, thereby ensuring the processing accuracy of the aluminum alloy door and window accessories.

[0018] 2. The aluminum alloy door and window processing and milling device, when the clamping seat is flipped 180 degrees to realize the processing of the other side of the aluminum alloy door and window accessories, under the guidance of the convex ball and the arc groove, the transmission cylinder is prompted to move horizontally toward the inner side of the clamping seat on the inner wall of the fixed cylinder, thereby pushing the contact plate to tightly press against the end of the aluminum alloy door and window accessories, and as the clamping seat continues to rotate, through the transmission of the inner piston rod and the outer piston rod in the piston cylinder, the contact ball guides the spiral groove to drive the transmission sleeve to rotate, and then under the restriction and guidance of the telescopic rod, the threaded disk moves toward the side away from the piston cylinder to change the maximum stretching distance of the reset spring, and appropriately reduce the pressing force of the inner piston rod and the contact plate on the aluminum alloy door and window accessories, which can ensure that the aluminum alloy door and window accessories will not deflect and disengage during the flipping process, and will not be dislocated due to excessive pressing force, thereby affecting the milling processing accuracy.

[0019] 3. The aluminum alloy door and window processing and milling device is provided with an anti-deflection component, which cooperates with the round rod and the inclined groove. When the transmission cylinder moves toward one side of the clamping seat, the limit plate is prompted to move toward the center of the clamping seat, and the limit bar is extended out of the clamping plate and plugged into the triangular groove opened at the end of the extension plate extended by the elastic force of the connecting spring, thereby producing a limiting effect on the extension plate on the surface of the clamping plate, avoiding the skewing and deflection of the accessories between the clamping plates due to the contact between the milling structure and the aluminum alloy door and window accessories, so as to ensure the overall milling processing accuracy of the device.

[0020] 4. The aluminum alloy door and window processing and milling device is provided with a torsion component. In the process that the contact plate and the end of the aluminum alloy door and window accessory gradually approach and press against each other, the contact plate first contacts the end of the accessory, and in the subsequent process that the contact plate gradually approaches each other, the contact plate moves toward the fixed sleeve along with the guide rod and the shrink sleeve. At this time, due to the guidance and restriction of the spiral chute and the guide ball, the shrink sleeve drives the guide rod and the contact plate to rotate until a position with a sufficiently large friction coefficient is maintained between the surface of the contact plate and the end of the aluminum alloy door and window accessory, thereby providing sufficient torsional force at the end of the aluminum alloy door and window accessory to improve the relative stability of the aluminum alloy door and window accessory during the milling processing operation.

[0021] 5. The aluminum alloy door and window processing and milling device is provided with an adapting component. During the process that the abutting plate contacts and presses against the end of the aluminum alloy door and window accessory, the end of the contact plate away from the fixing rod first contacts the end of the aluminum alloy door and window accessory. At this time, due to the uneven surface of the end of the aluminum alloy door and window accessory or the uneven condition due to the design, the contact plate can slide in a small range with the fixing rod as the guide direction. At this time, the elastic force of the small spring enables the contact plate to be pressed against the end surface of the aluminum alloy door and window accessory at the side. At the same time, due to the elastic force of the scroll spring, the contact plates corresponding to the two groups of adapting components on the side of the abutting plate are arranged in an "eight" shape, so as to better suppress the deflection of the aluminum alloy door and window accessory when clamped between the two groups of clamping plates, thereby ensuring the milling processing accuracy of the device on the aluminum alloy door and window.

A spiral groove 6996 is provided on the arc-shaped inner surface of the transmission sleeve 6995. A contact ball 6997 is fixedly installed on the arc-shaped outer wall of the outer piston rod 698.

[0036] For further information, please refer to the attached manual. Figure 1-Figure 6, a vertical plate for installing the stepper motor 3 and the threaded rod 4 is provided on the upper surface of the workbench 1 to ensure the horizontal installation of the threaded rod 4. At the same time, a horizontally arranged flat plate is provided on the side of the vertical plate, and the flat plate is in contact with the outer wall of the translation seat 5. At the same time, a guide post is provided between the two groups of vertical plates, and a through hole adapted to the guide post is opened in the inner wall of the translation seat 5. Thus, when the stepper motor 3 is started, in cooperation with the rotation of the threaded rod 4, the translation seat 5 can only move horizontally along the outer wall of the guide post and will not rotate with the rotation of the threaded rod 4. At the same time, the translation seat 5 is set in an L shape, and the clamping seat 62 is set in a U shape, so as to leave enough space for the rotation of the clamping seat 62 on the translation seat 5. In addition, the number of the hydraulic devices 66, the transmission rods 67 and the clamping plates 68 is set to two groups, and the two groups of hydraulic devices 66, the transmission rods 67 and the clamping plates 68 are symmetrically arranged on the upper and lower sides of the clamping seat 62 with the horizontal central axis of the clamping seat 62 as the symmetry axis, and the clamping plates 68 are arranged in parallel. At the same time, one side outer wall of the clamping plate 68 is in contact with the inner surface of the clamping seat 62 to ensure that the two clamping plates 68 can clamp the aluminum alloy door and window accessories on the upper and lower surface thereof, so as to facilitate the subsequent milling operation. Specifically, the driven gear 65 meshes with the driving gear 64 to achieve transmission. After the processing on one side surface of the aluminum alloy door and window accessories is completed, by starting the servo motor 63, the driving gear 64 is driven to drive the driven gear 65 to rotate 180°, so as to realize the up and down flipping of the clamping seat 62, and then drive the up and down flipping of the aluminum alloy door and window accessories fixed in the clamping seat 62 to expose the other side for milling processing, avoiding the processing precision error caused by manual replacement.

[0037] In addition, the outer diameter of the transmission cylinder 691 is adapted to the inner diameter of the fixed cylinder 61, and the outer diameter of the piston cylinder 695 is adapted to the inner diameter of the transmission cylinder 691. At the same time, the axial lines of the fixed cylinder 61, the transmission cylinder 691 and the piston cylinder 695 are arranged on the same straight line to ensure the relative stability of the movement of the transmission cylinder 691 and the piston cylinder 695. Furthermore, the latch 692 includes a pin rod and a compression spring. The compression spring is sleeved on the outside of the latch 692, and the two ends of the compression spring are respectively fixedly connected to the top outer wall of the pin rod and the arc-shaped outer wall of the transmission cylinder 691 to ensure the positioning stability of the latch 692 on the transmission cylinder 691. At the same time, a spring is provided on the arc-shaped outer wall of the piston cylinder 695 to match the latch 692. The adapted socket allows the piston cylinder 695 and the transmission cylinder 691 to maintain a relatively fixed position through the latch 692. Furthermore, there are two groups of latches 692, and the two groups of latches 692 are symmetrically arranged on the upper and lower sides of the transmission cylinder 691 with the horizontal center axis of the transmission cylinder 691 as the symmetry axis. Specifically, the inner piston rod 696 and the outer piston rod 698 are both provided with piston plates at one end of the inner wall close to the piston cylinder 695, and the internal cavity of the piston cylinder 695 is filled with helium. Due to the strong stability of helium and its low compressibility, the inner piston rod 696 and the outer piston rod 698 on the left and right sides of the piston cylinder 695 can maintain a relatively balanced state during transmission.

[0038] At the same time, the disc 6991 is arranged on the outer wall of one end of the outer piston rod 698 away from the piston cylinder 695, and the number of telescopic rods 6992 is arranged in three groups, and the three groups of telescopic rods 6992 are evenly distributed on the side wall of the disc 6991 in a circular array, and the reset spring 6994 is sleeved on the arc-shaped outer wall of the transmission sleeve 6995, but is in the gap between the three groups of telescopic rods 6992, so as to ensure that the reset spring 6994 will not be excessively deflected when deformed. Further, the transmission sleeve A threaded groove threadably connected to the threaded disk 6993 is provided on the arc-shaped outer wall of 6995, and a guide hole matching the size of the telescopic rod 6992 is provided on the inner wall of the threaded disk 6993 to prevent the threaded disk 6993 from rotating with the rotation of the transmission sleeve 6995. Specifically, when clamping and fixing the aluminum alloy door and window accessories, first pull out the pin 692, and manually push the transmission cylinder 691 toward the side of the clamping plate 68 to make the contact plate 697 fit with the end of the aluminum alloy door and window accessories.

[0039] When the milling process on one side of the aluminum alloy door and window fitting is completed and it needs to be rotated 180 degrees, the relative rotation between the fixed cylinder 61 and the translation seat 5 causes the transmission cylinder 691 to move horizontally toward the inside of the clamping seat 62 on the inner wall of the fixed cylinder 61 under the guidance of the convex ball 694 and the arc groove 693, thereby pushing the contact plate 697 to tightly contact the end of the aluminum alloy door and window fitting. As the clamping seat 62 continues to rotate, the inner piston rod 696 and the outer piston rod 698 in the piston cylinder 695 are driven to cooperate with the contact ball 6997 to The spiral groove 6996 guides the transmission sleeve 6995 to rotate, and then under the restriction and guidance of the telescopic rod 6992, the threaded disk 6993 moves toward the side away from the piston cylinder 695 to change the maximum stretching distance of the reset spring 6994, and appropriately reduce the tightening force of the inner piston rod 696 and the contact plate 697 on the aluminum alloy door and window accessories, which can ensure that the aluminum alloy door and window accessories will not deflect and disengage during the flipping process, and will not be dislocated due to excessive tightening force, thereby affecting the milling processing accuracy.

[0040] Please refer to the instruction manual Figure 7-Figure 8 In the embodiment of the present invention, the interior of the translation seat 5 is provided with an anti-deflection component 7 to prevent the end of the aluminum alloy door and window accessories from being offset and misaligned when clamped. The anti-deflection component 7 includes a push rod 71, which is fixedly mounted on the arc-shaped outer wall of the transmission cylinder 691. A T-shaped rod 72 is slidably mounted on the inner wall of the push rod 71. A round rod 73 is fixedly mounted on the inner wall of the end of the T-shaped rod 72 away from the push rod 71. A limit plate 75 is slidably mounted on the inner wall of the clamping plate 68. The limit plate 75 is close to the clamping seat. A limit strip 76 is fixedly installed on the outer wall on one side of the center of 62, and a transmission cavity with a width matching the width of the T-shaped rod 72 is opened on the inner wall of the limit plate 75, and an inclined groove 74 is opened on the inner wall of the transmission cavity. The end of the round rod 73 is arranged inside the inclined groove 74, and an extension plate 77 is slidably installed on the inner wall of the contact plate 697. A connecting spring 78 is fixedly connected between the end of the extension plate 77 and the inner wall of the contact plate 697, and a triangular groove 79 is opened on the outer wall of the extension plate 77 at one end close to the clamping plate 68.

[0041] Specifically, the inner wall of the clamping seat 62 is provided with a rectangular groove whose width is matched with the width of the push rod 71, so that the push rod 71 can slide in the horizontal direction inside the rectangular groove. At the same time, the number of push rods 71 ​​is provided in two groups, and the two groups of push rods 71 ​​are symmetrically arranged at the upper and lower ends of the transmission cylinder 691 with the horizontal central axis of the transmission cylinder 691 as the symmetry axis. A T-shaped sliding groove matched with the T-shaped rod 72 is provided inside the push rod 71, so that relative displacement between the push rod 71 and the T-shaped rod 72 can only occur in the vertical direction, and the two can maintain the same direction and speed movement in the horizontal direction. Further, A straight groove matching the size of the limit strip 76 is provided on the outer wall of the clamping plate 68 near the center of the clamping seat 62, and there are multiple groups of limit strips 76, which are evenly distributed in a linear array on the outer wall of the limit plate 75 near the center of the clamping seat 62. Specifically, the surface of the side of the limit strip 76 away from the limit plate 75 is set to be a triangle that matches the triangular groove 79, so that when the limit plate 75 moves toward the center of the clamping seat 62, the triangular structure of the limit strip 76 can be inserted into the inside of the triangular groove 79 to suppress the rotation tendency of the extension plate 77.

[0042] At the same time, there are two groups of extension plates 77, and the two groups of extension plates 77 are staggered on the inner walls of the upper and lower sides of the contact plate 697. Specifically, the end of the inclined groove 74 close to the push rod 71 is arranged close to the center of the clamping seat 62, and the end away from the push rod 71 is arranged away from the center of the clamping seat 62, so that the transmission cylinder 691 is affected by the convex ball 694 and the arc groove 693 and moves toward the center of the workbench 1. In the process, the push rod 71 pushes the T-shaped rod 72 to the right. Specifically, a square hole is provided at the bottom of the end of the clamping plate 68 close to the push rod 71, which is compatible with the end of the T-shaped rod 72, so that the T-shaped rod 72 can maintain a height of 1 to the clamping plate 68 in the vertical direction. The consistency of degree is ensured, and at the same time, a straight groove adapted to the width of the T-bar 72 is opened on the inner wall of the clamping seat 62, so as to avoid interference with the movement of the T-bar 72, thereby cooperating with the round rod 73 and the inclined groove 74 to prompt the limit plate 75 to move toward the center side of the clamping seat 62, and make the limit bar 76 extend out of the clamping plate 68, and plug into the triangular groove 79 opened at the end of the extension plate 77 extended by the elastic force of the connecting spring 78, so as to produce a limiting effect on the extension plate 77 on the surface of the clamping plate 68, and avoid the skewing and deflection of the accessories between the clamping plates 68 due to the contact between the milling structure 2 and the aluminum alloy door and window accessories, so as to ensure the overall milling processing accuracy of the device.

[0043] Please refer to the instruction manual Figure 8-Figure 9In an embodiment of the present invention, a torsion assembly 8 is provided inside the end of the contact plate 697 away from the inner piston rod 696 to provide a stable adhesion force when in contact with the aluminum alloy door and window accessories. The torsion assembly 8 includes a fixed sleeve 81. A storage groove is provided on the inner wall of the end of the contact plate 697 away from the inner piston rod 696. The fixed sleeve 81 is fixedly installed on the inner wall of the bottom end of the storage groove. A spiral chute 82 is provided on the inner wall of the fixed sleeve 81. A shrinkage sleeve 83 is movably installed inside the fixed sleeve 81. A guide ball 84 is provided on the arc-shaped outer wall of the shrinkage sleeve 83. The guide ball 84 is arranged inside the spiral chute 82. A guide rod 85 is slidably installed on the inner wall of the shrinkage sleeve 83. A compression spring 87 is fixedly connected between the end of the guide rod 85 and the inner wall of the shrinkage sleeve 83. A contact plate 86 is fixedly installed on the end of the guide rod 85 away from the compression spring 87.

[0044] In an embodiment of the present invention, the outer diameter of the shrink sleeve 83 is matched with the inner diameter of the fixed sleeve 81, so that the shrink sleeve 83 can move in the horizontal direction inside the fixed sleeve 81. Specifically, when the shrink sleeve 83 has a tendency of linear motion in the horizontal direction inside the fixed sleeve 81, due to the guidance and restriction of the guide ball 84 and the spiral chute 82, the shrink sleeve 83 can synchronously rotate and move in the horizontal direction inside the fixed sleeve 81. Furthermore, a strip limit block is provided on the arc-shaped outer wall of the guide rod 85, and a limit slot matched with the above-mentioned strip limit block is opened on the inner wall of the shrink sleeve 83, so that only a contraction between the shrink sleeve 83 and the guide rod 85 can occur. The contact plate 86 can generate linear motion in the horizontal direction without relative rotation. At the same time, a rubber belt is provided on the outer wall of the end of the contact plate 86 away from the guide rod 85. The rubber belt is provided in an S shape, and there are multiple groups of rubber belts, and the multiple groups of rubber belts are evenly distributed on the outer surface of the contact plate 86 in a circular array to improve the end friction coefficient of the contact plate 86 and the aluminum alloy door and window accessories, so as to provide a more stable contact effect during the tightening process. Specifically, an annular storage cavity matched with the end of the shrink sleeve 83 is provided on the inner wall of the end of the contact plate 86 close to the guide rod 85, so that the contact plate 86 will not be interfered with by movement when it moves toward the side of the shrink sleeve 83 along with the guide rod 85.

[0045] In the process of the contact plate 697 gradually approaching and pressing against the end of the aluminum alloy door and window accessory, the contact plate 86 first contacts the end of the accessory, and in the subsequent process of the contact plate 697 gradually approaching, the contact plate 86 moves toward the fixed sleeve 81 along with the guide rod 85 and the shrinking sleeve 83. At this time, due to the guidance and restriction of the spiral chute 82 and the guide ball 84, the shrinking sleeve 83 drives the guide rod 85 and the contact plate 86 to rotate until a position with a sufficiently large friction coefficient is maintained between the surface of the contact plate 86 and the end of the aluminum alloy door and window accessory. At this time, the shrinking sleeve 83 no longer slides relative to the fixed sleeve 81 due to the influence of the contact plate 86, and then the guide rod 85 shrinks along the inner wall of the shrinking sleeve 83, cooperating with the multiple sets of rubber belts arranged on the outer surface of the contact plate 86, thereby providing sufficient torsional force at the end of the aluminum alloy door and window accessory to improve the relative stability of the aluminum alloy door and window accessory during milling processing.

[0046] Please refer to the instruction manual Figure 7-Figure 8 as well as Fig.10 In an embodiment of the present invention, an adaption component 9 that adapts to different shapes and recesses of aluminum alloy door and window accessories is provided at one end of the contact plate 697 away from the inner piston rod 696. The adaption component 9 includes a fixing rod 91. A deflection cavity is provided on the inner wall of the end of the contact plate 697 away from the inner piston rod 696. The inner wall of the deflection cavity is fixedly connected to the fixing rod 91. A fixing ring 92 is passed through and fixedly installed on the arc-shaped outer wall of the fixing rod 91. A contact plate 94 is passed through and movably installed on the arc-shaped outer wall of the fixing rod 91. A small spring 93 is fixedly connected between the side wall of the contact plate 94 and the side wall of the fixing ring 92. A deflection groove 95 is provided on the inner wall of the end of the contact plate 94 close to the fixing rod 91, and a spiral spring 96 is provided inside the deflection groove 95.

[0047] It is worth noting that there are two groups of adaptation components 9, and the two groups of adaptation components 9 are symmetrically arranged with the vertical center axis of the contact plate 697 as the axis of symmetry, so that when the contact plate 697 is kept in tight contact with the end of the metal door and window accessory, the movement tendency of the end of the metal door and window accessory to deflect can be better suppressed. Furthermore, a rubber pad is provided on the side wall of the end of the contact plate 94 away from the fixing rod 91 to enhance the contact efficiency between the contact plate 94 and the end of the aluminum alloy door and window accessory. At the same time, there are two groups of fixing rings 92 and small springs 93, and the two groups of fixing rings 92 and small springs 93 are symmetrically arranged on the upper and lower sides of the contact plate 94 with the horizontal center axis of the contact plate 94 as the axis of symmetry. Specifically, the inner wall of the contact plate 94 is provided with a circular hole with a diameter matching the outer diameter of the fixing rod 91, so that the contact plate 94 can deflect with the fixing rod 91 as the rotation center while also pressing the outer wall of the fixing rod 91 to offset in the vertical direction.

[0048] At the same time, the two ends of the spiral spring 96 are respectively fixedly connected to the arc-shaped outer wall of the fixing rod 91 and the inner wall of the bottom end of the deflection groove 95, so that the contact plate 94 always has a movement tendency of reverse rotation to achieve reset when rotating with the fixing rod 91 as the rotation center. Further, in the process of the contact plate 697 contacting and pressing against the end of the aluminum alloy door and window accessory, the end of the contact plate 94 away from the fixing rod 91 first contacts the end of the aluminum alloy door and window accessory. At this time, due to the uneven surface of the end of the aluminum alloy door and window accessory or due to the design, In the case of uneven conditions, the contact plate 94 can slide in a small range guided by the fixed rod 91. At this time, the elastic force of the small spring 93 enables the contact plate 94 to be tightly attached to the end surface of the aluminum alloy door and window accessories at the side. At the same time, due to the elastic force of the spiral spring 96, the contact plates 94 corresponding to the two groups of adaptation components 9 on the side of the contact plate 697 are arranged in an "eight" shape, so as to better suppress the deflection of the aluminum alloy door and window accessories when clamped between the two groups of clamping plates 68, thereby ensuring the milling processing accuracy of the device on the aluminum alloy doors and windows.

[0049] In the present invention, when in use, firstly, one end of the aluminum alloy door and window accessory is placed between the two sets of clamping plates 68, and the specific position of the accessory on the clamping plate 68 is adjusted according to the pre-measured processing position of the aluminum alloy door and window accessory, and then the two sets of hydraulic devices 66 are controlled to push the clamping plate 68, and then the aluminum alloy door and window accessory is clamped in the vertical direction. At this time, the latch 692 is pushed outward to release the limit of the transmission cylinder 691, and then the transmission cylinder 691 is manually pushed toward one side of the clamping plate 68, so that the contact plate 697 and the end of the aluminum alloy door and window accessory are attached and pressed tightly, and then Release the latch 692 to achieve auxiliary positioning of the end of the aluminum alloy door and window accessories at a suitable position, and finally start the stepper motor 3, cooperate with the threaded rod 4 and the guide column, so that the translation seat 5 drives the clamping seat 62 to approach the milling structure 2 in the horizontal direction. At this time, start the milling structure 2 to perform milling processing on the surface of the aluminum alloy door and window accessories positioned by the clamping plate 68. After the milling processing of the surface is completed, the stepper motor 3 is controlled to flip so that the translation seat 5 drives the clamping seat 62 to move toward the side away from the milling structure 2 until the translation seat 5 moves to the side close to the stepper motor 3.

[0050] Then, the servo motor 63 is started to drive the active gear 64 to drive the driven gear 65 to rotate 180°, thereby realizing the upside-down flipping of the clamping seat 62, and then driving the aluminum alloy door and window accessories fixed in the clamping seat 62 to flip upside-down to expose the other side for milling processing. Then, the above steps are repeated to start the stepper motor 3 again to control the translation seat 5 to drive the aluminum alloy door and window accessories to perform milling processing on the other side, thereby avoiding processing accuracy errors caused by manual transposition.

[0051] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
