Description

Technical Field

[0001] The invention relates to the field of aluminum profile processing, and in particular to an anti-deformation aluminum profile cutting device and a cutting method. Background Art

[0002] Aluminum profiles are widely used. They can be used as brackets for production line equipment, as frames for doors and windows, and on some high-precision equipment. The cutting and processing of aluminum profiles includes cutting, shaving, milling and other processes. Especially for aluminum profiles used on high-precision equipment, high cutting accuracy is required. Traditional cutting methods cannot meet such cutting operations. Milling cutters are required for cutting. When milling cutters are used to cut aluminum profiles, according to different application scenarios of aluminum profiles, it is necessary to select a milling cutter with a suitable diameter for cutting to achieve the best processing efficiency.

[0003] The current milling cutter disc processing diameter adjustment range is achieved by replacing the milling cutter or the milling cutter disc. For example, the Chinese patent with the announcement number CN207267279U discloses a machine-clamped PCD woodworking disc milling cutter, which includes a cutter disc, a pin, an adjustment block, a wedge block, a stud, a chip breaker block, and a cutter block; the blade is welded to the cutter head, and the blade and the cutter head together constitute the cutter block, and slots are provided at both ends of the cutter block, and the chip breaker block is connected to the adjustment block through a pin, and wedge blocks are provided on both sides of the adjustment block, and the wedge blocks are connected to the cutter disc through studs;

[0004] This type of machine-clamped PCD woodworking disc milling cutter has a blade welded on the cutter head, and the cutter block is fixedly connected to the cutter disc. Since the size of the blade is fixed, the diameter of the milling cutter chips cannot be adjusted. When processing parts of different sizes, disc milling cutters of different diameters need to be prepared according to the size of the processed parts, which not only increases the processing cost, but also greatly affects the processing efficiency.

[0005] In this regard, the Chinese patent with the announcement number CN209206561U discloses a disc milling cutter with adjustable section size, including a tool holder and a blade fixed on the tool holder, the tool holder including a disc and a connecting plate evenly distributed on the disc in the circumferential direction, the disc is provided with a fixed shaft in a direction perpendicular to the disc, the connecting plate is provided with a slide groove, a square tool rod is fixed on the blade, the tool rod is slidably connected in the slide groove, the tool rod is threadedly connected with locking caps at the upper and lower ends of the connecting plate, and a telescopic component for adjusting the position of the tool rod is provided between the tool rod and the fixed shaft;

[0006] It achieves diameter adjustment by installing the tool rod on the telescopic component, but its adjustment range is limited to the size of the tool holder. The telescopic component needs to ensure the area of ​​the intersection with the connection point with the tool holder. If the area is too small, it will affect the connection stability. If the area is too large, it will occupy too much area of ​​the tool holder, resulting in a small adjustment size range and little change in diameter. In addition, it uses a linear adjustment structure. Even with a locking structure, the tool holder is always subjected to force in a single direction during operation, which affects the life and reliability of the connection point between the telescopic component and the tool holder.

DETAILED DESCRIPTION

[0043] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0044] Embodiment 1

[0045] See also Figure 1 , Fig.10 and Fig.11 As shown, an anti-deformation aluminum profile cutting device includes a disk rod 1, a cutter disk mechanism and a milling cutter 16, a first acquisition module, a second acquisition module and a speed identification module, wherein the first acquisition module, the second acquisition module and the speed identification module are connected via a wired and / or wireless network, a flat groove (not shown) is provided on the surface of the disk rod 1 to facilitate connection and positioning with an external structure, and is fixed to the end of the disk rod 1, and the milling cutter 16 is fixed on the cutter disk mechanism;

[0046] The first acquisition module is used to collect the real-time rotation speed value of the disc rod 1. In this embodiment, the first acquisition module adopts a rotation speed sensor or a sensor with a rotation speed detection function, which is not specifically limited here. The first acquisition module is installed at the connection between the disc rod 1 and the output part of the machining center 100;

[0047] The second acquisition module is used to collect the real-time temperature value of the cutting part. In this embodiment, the second acquisition module adopts a thermal probe or a sensor with a non-contact temperature measurement function, which is not specifically limited here. The second acquisition module is fixed on the machining center 100, and the detection part of the second acquisition module faces the cutting part;

[0048] The speed recognition module is used to input the real-time speed value and the real-time temperature value into the trained speed recognition model, and output the target speed value, which is used as the adjustment parameter of the speed of the disc 1; the hardware of the speed recognition module in this embodiment is a device with a communication unit and capable of performing logical operations, such as a PLC or a single-chip microcomputer, etc., which is not specifically limited here;

[0049] The purpose is that the speed identification model outputs the target speed value as the speed of the machining center 100 to control the disk rod 1, which can control the speed of the disk rod 1 during machining, and thus control the temperature of the cutting part during machining, to avoid excessive speed and the aluminum profile cutting part heating up too quickly and causing thermal deformation.

[0050] For example, when cutting aluminum profiles, the disk rod 1 is connected and fixed to the output part of the machining center 100, and the aluminum profile is fixed on the machining table 200 by a clamp. The machining center 100 drives the disk rod 1 to rotate, and the cutter disc mechanism drives the milling cutter 16 to rotate quickly to cut the aluminum profile.

[0051] For details, see Figure 2 and Figure 3As shown, the cutter disc mechanism includes a cutter disc 2, a first cover 3, an extension arm 6 and a diameter adjustment assembly. The cutter disc 2 is fixed to the end of the disc rod 1, the first cover 3 is fixedly connected to the cutter disc 2, and a second cover 4 is provided on the side of the cutter disc 2 away from the first cover 3. Countersunk holes are evenly opened in the middle of the second cover 4, and fixing bolts 5 are inserted into the countersunk holes. The fixing bolts 5 are inserted on the cutter disc 2 and the disc rod 1, and the fixing bolts 5 are threadedly connected to the disc rod 1, as shown in FIG. Figure 6 As shown, the cutter disc 2 is sandwiched between the first cover 3 and the second cover 4, and the three are fixedly connected together by fixing bolts 5, which is convenient for assembly and later maintenance.

[0052] Specifically, Figure 2 and Figure 6 As shown, the extension arm 6 is rotatably connected to the cutter disc 2, a milling cutter 16 is fixed at the end of the extension arm 6, the cutter disc 2 and the edge of the first cover 3 are wedge-shaped, which reduces the shielding area of ​​the milling cutter 16 when the cutter disc mechanism is tilted, and the diameter adjustment assembly is composed of a transmission arm 7, a driving arm 8, a worm 9, a driven bevel gear 10, an active bevel gear ring 11 and a fixed pile 13, and the active bevel gear ring 11 is rotatably connected to the disc rod 1, a positioning groove is provided in the middle of the cutter disc 2, and a positioning block is integrally connected to the end of the disc rod 1, and the positioning block is engaged with the positioning groove, which is conducive to the disc rod 1 driving the cutter disc 2 to move synchronously;

[0053] For more details, see Figure 4 , Figure 5 and Figure 6 As shown, the fixed pile 13 is fixed on the cutter disc 2, the worm 9 is rotatably connected to the fixed pile 13, the driven bevel gear 10 is fixed to the end of the worm 9, and the driven bevel gear 10 is meshed with the active bevel gear ring 11, the transmission arm 7 is slidably connected to the cutter disc 2, and the driving arm 8 is fixed on the transmission arm 7; Figure 3 As shown, worm gear teeth are evenly arranged on the edge of the driving arm 8, and the worm gear teeth are matched with the worm 9, so that the driving arm 8 and the worm 9 are meshed; illustratively, when the worm 9 rotates, it can drive the driving arm 8 to rotate with the connection point of the extension arm 6 and the cutter disc 2 as the center of the circle, and the end of the transmission arm 7 away from the driving arm 8 is fixedly connected to the extension arm 6. When the driving arm 8 rotates with the connection point of the extension arm 6 and the cutter disc 2 as the center of the circle, it can drive the transmission arm 7 to synchronously drive the extension arm 6 to rotate.

[0054] Further, such as Figure 3 and Figure 4 As shown, the extension arm 6 is arc-shaped, and the edge of the extension arm 6 is flush with the edge of the cutter disc 2. When the extension arm 6 overlaps with the cutter disc 2, the milling cutter 16 will not be affected.

[0055] Furthermore, a third guide groove 21 is provided on the outer surface of the cutter disc 2. The third guide groove 21 is arc-shaped, and the center of the third guide groove 21 is concentric with the connection point between the extension arm 6 and the cutter disc 2. The transmission arm 7 is slidably connected to the third guide groove 21, which improves the movement stability of the transmission arm 7 and limits the movement trajectory of the transmission arm 7. The end of the transmission arm 7 is flush with the cutter disc 2 and will not affect the milling cutter 16.

[0056] Preferably, Figure 3 and Figure 4 As shown, a second guide groove is opened on the side of the cutter disc 2, the second guide groove is arc-shaped, and the center of the second guide groove is concentric with the connection point between the extension arm 6 and the cutter disc 2. The connection point between the transmission arm 7 and the extension arm 6 can be embedded in the second guide groove, so that after the extension arm 6 is retracted, the transmission arm 7 will not protrude from the cutter disc 2.

[0057] like Figure 2 , Figure 5 and Figure 7 As shown, in order to ensure the stability of the active conical gear ring 11, a locking assembly is installed on the disk rod 1, and the locking assembly consists of a limit gear ring 12, a connecting block 14 and a spring 15. The limit gear ring 12 is sleeved on the disk rod 1, and the limit gear ring 12 is slidably connected to the disk rod 1. The connecting block 14 is fixed on the inner wall of the limit gear ring 12. A limit groove 101 is provided on the outer surface of the disk rod 1, and the connecting block 14 is slidably connected to the limit groove 101. The limit gear ring 12 can only slide vertically up and down through the cooperation between the connecting block 14 and the limit groove 101. A first positioning hole is provided on the inner wall of the limit groove 101, and a second positioning hole is provided on the outer surface of the connecting block 14. The two ends of the spring 15 are respectively embedded in the first positioning hole and the second positioning hole, which is convenient for the assembly of the spring 15. The spring 15 is used to provide elastic force to the connecting block 14, so that the limit block and the limit gear ring 12 are always against the active conical gear ring 11;

[0058] Specifically, Figure 1 and Figure 7 As shown, first tooth grooves are evenly formed on the opposite surfaces of the limiting gear ring 12 and the active conical gear ring 11, and second tooth grooves are evenly formed on the opposite surfaces of the active conical gear ring 11 and the limiting gear ring 12. The first tooth grooves are engaged with the second tooth grooves to keep the active conical gear ring 11 fixed.

[0059] Working principle: When in use, the disc rod 1 is connected to the driving mechanism of the external milling machine, and the milling cutter 16 is installed on the extension arm 6. The disc rod 1 is driven to rotate by the external milling machine driving mechanism, which can drive the extension arm 6 and the milling cutter 16 to rotate and perform milling on the workpiece;

[0060] When the processing diameter needs to be adjusted, stop the external driving mechanism, then manually push the limiting gear ring 12 away from the active conical gear ring 11, and then rotate the active conical gear ring 11, so that the active conical gear ring 11 drives the driven conical gear 10 to rotate, and the driven conical gear 10 drives the driving arm 8 through the worm 9 to rotate with the connecting axis between the extension arm 6 and the cutter disc 2 as the center, so that the driving arm 8 drives the extension arm 6 to expand outward through the transmission arm 7, changing the distance from the extension arm 6 to the center of the cutter disc 2, and then changing the processing diameter.
