Description

Technical Field

[0001] This application relates to the field of automated processing technology, and in particular to a cutting device for cutting arc-shaped openings at both ends of an aluminum alloy profile. Background Technology

[0002] There are three main methods for processing the curved ends of aluminum alloy profiles: CNC machining, laser cutting, and waterjet cutting. Specifically: CNC machining requires manual loading and is limited by the size of the CNC center, which restricts the size of the processed profiles; laser cutting has limited processing depth, and processing the bottom area affects the dimensional accuracy of the upper area. It also has the problems of large equipment footprint, requiring dedicated dust removal and cooling systems, thermal deformation, and energy loss due to the reflectivity of the profile to the laser; waterjet cutting has a much lower processing speed than CNC machining and laser cutting, and is only suitable for special scenarios with extremely high requirements for thermal deformation. Summary of the Invention

[0003] This application provides a cutting device for cutting arc-shaped openings at both ends of an aluminum alloy profile. The arc-shaped openings at both ends of the aluminum alloy profile are processed by adjusting the position and using a swinging method.

Detailed Implementation

[0043] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.

[0044] This application discloses a cutting device for cutting arc-shaped openings at both ends of an aluminum alloy profile. Please refer to [link / reference]. Figure 1 In some examples, the cutting device disclosed in this application for cutting arc-shaped openings at both ends of an aluminum alloy profile includes a base 1, a swing module 2, a turntable module 3, a milling module 4, a first fixing fixture 5, and a second fixing fixture 6. Specifically, the swing module 2, the turntable module 3, and the milling module 4 are all mounted on the base 1, and the swing module 2 and the turntable module 3 move linearly back and forth on the base 1. The milling module 4 is fixedly connected to the base 1.

[0045] Before the processing begins, the swing module 2 and the turntable module 3 adjust the position of the workpiece (aluminum alloy profile). Their function is to adjust the relative position of the workpiece and the milling module 4. During the processing, the swing module 2 drives the workpiece to swing. At the same time, the workpiece swings relative to the milling module 4, and the arc-shaped opening is processed during the swing.

[0046] As can be seen from the above description, the position of the milling module 4 remains stationary, meaning that the milling module 4 needs to be fixedly mounted on the base 1. It can also be seen that the turntable module 3 is located between the swing module 2 and the milling module 4.

[0047] The first fixing fixture 5 is fixedly installed on the swing module 2, and the second fixing fixture 6 is fixedly installed on the turntable module 3. The function of the first fixing fixture 5 and the second fixing fixture 6 is to fix the workpiece and prevent it from vibrating during the processing.

[0048] It should be noted that the aluminum alloy profiles in this application refer to functional aluminum alloy profiles with hollow and spatial structures. Here, it is necessary to further introduce the processing method of such aluminum alloy profiles with spatial structures in conjunction with the background technology.

[0049] Both laser cutting and waterjet cutting methods require processing this type of aluminum alloy profile from top to bottom. This results in the gap width in the upper area being larger than that in the lower area, making it difficult to control the dimensional accuracy of the entire processed surface.

[0050] The machining method used in this application is milling, in which the entire machined surface is directly removed during the machining process. The process parameters involved in the machining process are described below:

[0051] Cutting speed: 100–300 m / min (carbide tools);

[0052] Feed per tooth: 0.05–0.3 mm / z;

[0053] Axial cutting depth: 1–10 mm;

[0054] Spindle speed: n=1000vc / (πD) r / min, where v is the cutting speed.

[0055] Describe it using an actual processing method:

[0056] The workpiece (aluminum alloy profile) is placed on the swing module 2 and the turntable module 3 and fixed by the first fixing fixture 5 and the second fixing fixture 6. At this point, it is assumed that the position has been adjusted. Then, the milling module 4 is started to cut the workpiece. The swing module 2 moves synchronously to drive the workpiece to swing. During one complete swing, an arc-shaped opening appears at the end of the workpiece.

[0057] The specific number of oscillations needs to be determined based on the size of the arc-shaped opening, because the arc-shaped opening determines the machining amount, and the machining amount combined with the feed rate can be used to calculate the number of oscillations of the workpiece.

[0058] The distance between the turntable module 3 and the milling module 4 is a fixed value if the swing module 2 swings once. If the swing module 2 swings multiple times, the distance between the turntable module 3 and the milling module 4 has multiple fixed values. The distance between the turntable module 3 and the milling module 4 decreases by a fixed value with each swing.

[0059] However, when the structural strength of the workpiece is low, the distance between the turntable module 3 and the milling module 4 needs to be appropriately reduced to improve the stability of the part of the workpiece extending from the turntable module 3.

[0060] In some examples, please refer to Figure 2 The swing module 2 includes a first movable chassis 21, a first electrically controlled turntable 22, and a linear module 23. The first movable chassis 21 is mounted on the base 1 and moves linearly back and forth on the base 1. The first electrically controlled turntable 22 is fixedly mounted on the first movable chassis 21, and the linear module 23 is fixedly mounted on the first electrically controlled turntable 22.

[0061] The first movable chassis 21 is responsible for moving on the base 1. During this movement, the distance between the first movable chassis 21 and the swing module 2 will change (increase or decrease) to accommodate workpieces of different lengths. The first electrically controlled turntable 22 is responsible for driving the linear module 23 to rotate on the horizontal plane.

[0062] In some examples, the first movable chassis 21 is connected to the track on the base 1 via a slider. A rack is installed on the base 1, and the servo motor on the first movable chassis 21 meshes with the rack via gears to realize the reciprocating movement of the first movable chassis 21 on the base 1.

[0063] The first fixed fixture 5 is fixedly mounted on the moving platform of the linear module 23. When the linear module 23 is working, the distance between the first fixed fixture 5 and the center position of the first moving chassis 21 changes, the purpose of which is to adjust the swing angle range of the workpiece. Figure 3 and Figure 4 As shown.

[0064] It should also be noted that when the moving stage of the linear module 23 slides, the distance between the first fixed fixture 5 and the second fixed fixture 6 will change. At this time, a slide rail needs to be added between the moving stage of the linear module 23 and the first fixed fixture 5. The axis of the slide rail should be aligned with the length direction of the workpiece on the first fixed fixture 5. Figure 10 As shown.

[0065] Please see Figure 5 The first fixed clamp 5 includes a first rotating base 51, a first clamping groove 52 and a first floating clamping plate 53. The first rotating base 51 is mounted on the moving platform of the linear module 23 and is rotatably connected to the moving platform of the linear module 23. The first clamping groove 52 is located on the first rotating base 51.

[0066] The first rotating base 51 is rotatably connected to the moving stage of the linear module 23, which means that when the first electrically controlled turntable 22 rotates, the first rotating base 51 will also rotate relative to the moving stage of the linear module 23. The combination of these two rotations enables the workpiece to swing.

[0067] The first clamping groove 52 has a bottom surface and two side surfaces, and a first floating clamping plate 53 is installed on each of the three surfaces. The floating body on the first floating clamping plate 53 can extend and retract, driving the clamping fixture installed on the floating body to fix the workpiece.

[0068] In some possible implementations, the first floating clamping plate 53 is operated by hydraulic drive. Specifically, the first floating clamping plate 53 has a hydraulic chamber inside, a portion of the floating block is located inside the hydraulic chamber, and a portion extends out of the hydraulic chamber, which is filled with hydraulic oil.

[0069] The first floating clamping plate 53 is powered by a motor and a piston. The piston is located in the adjustment chamber of the hydraulic chamber. When the motor drives the piston to move, the volume of the hydraulic chamber changes, thereby controlling the extension and retraction of the floating block.

[0070] In some possible implementations, the clamping fixture uses a contour-following design, meaning the shape of the clamping surface of the fixture is the same as the shape of the clamped surface on the workpiece. The purpose of using contour-following design is to maximize the contact area and avoid deformation at the clamping location on the workpiece. Figure 6As shown by the dotted line, there is a positioning hole on the right side of the clamping fixture, and there is also a fixing hole that matches the positioning hole.

[0071] When installing the clamping fixture, it is secured to the piston of the first floating clamping plate 53 using bolts. In this application, the installation method of the clamping fixture remains the same, the difference being the contact surface, which is determined according to the shape of the workpiece.

[0072] In some possible implementations, the clamping fixture is made of a flexible material such as polytetrafluoroethylene.

[0073] In some examples, please refer to Figure 2 The turntable module 3 includes a second movable chassis 31 and a passive turntable 32. The second movable chassis 31 is mounted on the base 1, and the passive turntable 32 is mounted on the second movable chassis 31. The second movable chassis 31 moves linearly back and forth on the base 1, specifically moving towards and away from the milling module 4.

[0074] Movement has two functions:

[0075] Adjust the distance between the milling module 4 and the milling module 4;

[0076] During the multiple feed processes, the distance between the workpiece and the milling module 4 decreases.

[0077] Please see Figure 7 The second fixed clamp 6 includes a second rotating base 61 mounted on the passive turntable 32 and a second clamping groove 62 formed on the second rotating base 61. The second clamping groove 62 has a bottom surface and two side surfaces, and a second floating clamping plate 63 is mounted on each of the three surfaces. The structure of the second floating clamping plate 63 is the same as that of the first floating clamping plate 53, and will not be described in detail here.

[0078] In some examples, please refer to Figure 1 Furthermore, a reversing module 7 was added to the base 1. The function of the reversing module 7 is to place the workpiece on the swing module 2 and the turntable module 3 and to adjust the orientation of the workpiece. Specifically, when the reversing module 7 is not added, the workpiece needs to be placed manually on the swing module 2 and the turntable module 3. After one end of the workpiece is processed, the orientation of the workpiece is adjusted to complete the processing of the other end of the workpiece.

[0079] With the addition of the reversing module 7, the reversing module 7 can undertake this reversing work, and at the same time, it can also undertake the loading and unloading work. This will be described in conjunction with the specific structure of the reversing module 7.

[0080] In one possible implementation of this application, please refer to Figure 2 and Figure 8The reversing module 7 includes a third movable chassis 71, a lifting platform 72 (worm gear structure), a second electrically controlled turntable 73, and a clamp 74. The third movable chassis 71 is mounted on the base 1 and moves linearly back and forth on the base 1. The structure of the third movable chassis 71 is the same as that of the first movable chassis 21 and the second movable chassis 31, and will not be described in detail here.

[0081] The lifting platform 72 is mounted on the third mobile chassis 71 and is responsible for adjusting the height in the longitudinal direction. The lifting platform 72 is equipped with a second electrically controlled turntable 73, which drives the two clamps 74 mounted on the second electrically controlled turntable 73 to rotate.

[0082] Both clamps 74 are located at the edge of the second electrically controlled turntable 73 and the axes of the two clamps 74 are on the same straight line. Specifically, the function of the two clamps 74 is to temporarily fix the workpiece. Taking the horizontal placement of the base 1 as an example, when the line connecting the two clamps 74 is a horizontal line, the clamps 74 are located at the processing position. When the line connecting the two clamps 74 is a vertical line, the clamps 74 are located at the loading and unloading position.

[0083] The workpiece moves from one side of the base 1 to above the two clamps 74, and then the two clamps 74 rise to fix the workpiece. Then the third moving base 71 rotates 90 degrees and descends, and the first fixing clamp 5 and the second fixing clamp 6 fix the workpiece. After the fixation is completed, the two clamps 74 disengage from the workpiece.

[0084] When the workpiece is reversed, the two grippers 74 rise and fix the workpiece. At this time, the first fixing fixture 5 and the second fixing fixture 6 disengage from the workpiece, and the third moving chassis 71 rotates 180 degrees. The rotation process of the workpiece is as follows: Figure 9 As shown.

[0085] The first fixing fixture 5 and the second fixing fixture 6 fix the workpiece. After fixing, the two clamps 74 disengage from the workpiece.

[0086] After both ends of the workpiece are processed, the placement process of the workpiece is reversed, so that it can be transferred to a subsequent location or transported to a storage area (such as a warehouse) for storage.

[0087] It should be understood that the power source provided in this application is an electric motor. The electric motor is divided into two types: servo motor and three-phase motor. Both servo motor and three-phase motor are controlled by a programmable logic controller. The programmable logic controller and its supporting circuit are generally deployed below the milling module 4 and then connected to the motor through cables (power supply cables and control cables).

[0088] The embodiments described in this specific implementation are 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.
