Description

Technical Field

[0001] This invention relates to the field of aluminum profile cutting equipment technology, specifically a multi-angle inclined plane cutting equipment for the production of aluminum alloy pipe fittings. Background Technology

[0002] Aluminum alloy pipe fittings are widely used in aerospace, new energy vehicles and building structures due to their lightweight, corrosion resistance and high strength. In actual assembly scenarios, the two ends of the pipe fittings often need to be cut with high precision bevels to achieve sealing connection or fluid guidance, such as 45° bevel connection of refrigeration system pipes.

[0003] For example, Chinese Patent Publication No. CN119952139B relates to the field of aluminum profile cutting equipment technology, specifically a high-efficiency cutting equipment for producing thin-walled aluminum alloy parts. It includes a support base, a rotatable cutting seat rotatably mounted on the upper end of the support base, a cutting tool movably connected to the upper end of the rotatable cutting seat, and calibration backplates fixedly connected to the upper surfaces of both ends of the support base. This invention employs an optimized design of the calibration backplate to calibrate and abut one side of the aluminum profile. The rotatable cutting seat enables cutting of different bevels of the aluminum tube. Combined with an adaptive adjustment component, it can meet the abutment requirements of different cutting angles. It also integrates intelligent calibration to ensure the accuracy of the aluminum tube end abutment, preventing offset and wobbling vibration during cutting. Furthermore, the aluminum chip cleaning component and the adaptive adjustment component work together to achieve automated cleaning of aluminum chips, preventing cutting debris from affecting work efficiency.

[0004] Although the cutting equipment can cut aluminum alloy pipes at multiple angles, it still requires manual adjustment by the operator rotating the rotatable cutting seat. This not only significantly reduces processing efficiency and increases labor costs, but also makes it easy for human error to cause the parallelism of the two bevels to exceed the tolerance during repeated clamping. Especially in mass production, factors such as operator fatigue will further amplify the angle deviation, resulting in problems such as poor fit and sealing failure when assembling the cut pipes.

[0021] This invention achieves high-precision machining of the beveled surfaces of aluminum alloy pipe fittings through a mechanically adaptive structure. Its working principle is as follows: when the pipe fitting is installed in the clamping assembly, the adjusting disc automatically corrects the angle through mechanical transmission upon contacting the beveled surface, ensuring the beveled surface is perpendicular to the reference plane. A synchronous linkage mechanism transmits the angle of the adjusting disc to the cutting blade, ensuring the cutting plane is parallel to the beveled surface. A hydraulic system drives the cutting blade to complete precision cutting. The advantages of this design are: the fully mechanical adaptive adjustment eliminates the need for manual tool setting, significantly improving machining efficiency; the continuous contact pressure applied by the adjusting disc dynamically compensates for minute displacements caused by cutting forces, ensuring cutting stability; the unique parallelism maintenance mechanism ensures the consistency of workpiece angles during batch processing, making it particularly suitable for pipeline systems requiring precise docking, effectively improving pipe fitting assembly quality and sealing performance; the entire system requires no electronic sensors or complex control systems, achieving reliable machining solely through a purely mechanical structure, offering advantages such as strong anti-interference and simple maintenance.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 10 The present invention provides a technical solution: a multi-angle inclined cutting device for the production of aluminum alloy pipe fittings, comprising a support base 1, characterized in that: a support plate 2 is fixedly installed on the top of the support base 1, an mounting base 5 is rotatably installed on the top of the support base 1, a cutting blade 6 that can be vertically slidably adjusted is installed on the upper end of the mounting base 5, a fixing plate 7 that can be horizontally slidably adjusted is installed on the top of the support plate 2, a control rod 21 is fixedly installed on the outer wall of the fixing plate 7 near the aluminum alloy pipe fitting 3, and an adjusting disk 20 is rotatably installed on the other end of the control rod 21, and the rotation center of the adjusting disk 20 coincides with the axis of the aluminum alloy pipe fitting 3;

[0035] It also includes two sets of clamping assemblies installed on the top of the support plate 2. The clamping assemblies have a clamping state for holding the aluminum alloy tube 3 and a rotation state for releasing its axial degree of freedom.

[0036] It also includes an adjustment component that ensures that the adjustment disc 20 is always parallel to the cutting plane of the cutting blade 6.

[0037] See Figure 1 as well as Figure 2When using this device to cut aluminum alloy pipe 3, the operator horizontally inserts the aluminum alloy pipe 3 to be cut into the two clamping assemblies, with the inclined surface of the aluminum alloy pipe 3 facing towards the adjusting plate 20. The clamping assemblies clamp the aluminum alloy pipe 3 and release its axial lock, allowing it to rotate freely along the axis. At this time, the external drive assembly drives the fixing plate 7 to move horizontally towards the aluminum alloy pipe 3, causing the control rod 21 and the adjusting plate 20 to move forward synchronously. As the adjusting plate 20 gradually approaches the aluminum alloy pipe 3, the working surface of the adjusting plate 20 contacts the aluminum alloy pipe 3. When the aluminum alloy tube 3 comes into contact with the metal fitting, the adjusting disk 20 rotates under the action of the contact force, and the adjusting disk 20 applies pressure to the inclined surface of the aluminum alloy tube 3. Through mechanical transmission, the aluminum alloy tube 3 rotates until the inclined surface of the aluminum alloy tube 3 is completely in contact with the working surface of the adjusting disk 20 after rotation. This automatic alignment process is completed entirely by the self-adaptive nature of the mechanical structure without manual intervention, so as to ensure that the inclined surface of the aluminum alloy tube 3 is completely perpendicular to the top of the support plate 2, so that the cutting surface of the cutting blade 6 can be completely parallel to the inclined surface of the aluminum alloy tube 3 when cutting the aluminum alloy tube 3 later.

[0038] When the adjusting plate 20 contacts the inclined surface of the aluminum alloy tube 3, causing the inclined surface of the aluminum alloy tube 3 to rotate to be perpendicular to the surface of the support plate 2, the angle of the cutting blade 6 is adjusted to match the rotation angle of the adjusting plate 20 via the adjusting assembly. That is, the cutting plane of the cutting blade 6 is parallel to the working plane of the adjusting plate 20. Therefore, at this time, the cutting plane of the cutting blade 6 is parallel to the inclined surface of the aluminum alloy tube 3. After the angle adjustment of the cutting blade 6 is completed, the aluminum alloy tube 3 is completely locked by the clamping assembly, putting it in a fixed processing state to prevent rotation during cutting. The hydraulic drive system above the mounting base 5 causes the cutting blade 6 to move downwards gradually. The motor fixed to the mounting housing of the cutting blade 6 drives the cutting blade 6 to rotate, thereby completing the bevel cutting of the aluminum alloy tube 3. As the cutting blade 6 continues to feed, the newly formed cutting surface maintains a strict parallel relationship with the original bevel of the aluminum alloy tube 3. When the cutting depth reaches the preset value, the displacement sensor triggers a stop signal, and the cutting blade 6 automatically returns to the initial position. At this time, the clamping assembly is released, and the operator can take out the processed workpiece to complete the next processing step.

[0039] The entire machining process achieves automatic angle alignment and precise control of the cutting trajectory through the self-adaptive nature of the mechanical structure, eliminating the need for manual angle adjustment. This not only improves machining efficiency but also ensures the consistency of workpiece angles in mass production. Especially for pipeline systems that require high-precision docking, this machining method that automatically ensures the parallelism of the inclined surfaces at both ends can significantly improve the assembly quality and sealing performance of the pipe fittings.

[0040] Of particular note is that during the cutting process, the adjusting plate 20 continuously applies stable contact pressure to the aluminum alloy tube 3, and automatically compensates for the slight displacement that the aluminum alloy tube 3 may cause due to the cutting force through the mechanical feedback mechanism. In conjunction with the clamping assembly, the aluminum alloy tube 3 is further fixed to ensure the stability of the cutting process.

[0041] Furthermore, the adjustment assembly includes two sliding rods 22 that penetrate the outer wall of the fixed plate 7 and are symmetrically installed. Both sliding rods 22 are slidably connected to the fixed plate 7 at the penetration point. One end of each sliding rod 22 contacts and abuts against the adjustment disc 20. A first spring 23 is installed between each sliding rod 22 and the fixed plate 7. A rotating rod 26 is vertically installed through the outer wall of the control rod 21 and is rotatably connected to the control rod 21 at the penetration point. A balance plate 24 is fixedly installed on the top of the rotating rod 26. Two symmetrically distributed grooves are opened on the outer wall of the balance plate 24. Rollers 25 that can slide in the grooves of the balance plate 24 are fixedly installed on the outer walls of the two sliding rods 22.

[0042] It also includes an adjustment section that ensures the side plane of the balance plate 24 is always parallel to the cutting plane of the cutter 6.

[0043] See Figure 2 as well as Figure 5 After the workers initially fix the aluminum alloy pipe fitting 3 using the clamping assembly and release its axial lock, the aluminum alloy pipe fitting 3 is now in a freely rotatable state, such as... Figure 5 As shown, a cylinder is mounted on the top of the support base 1 via a vertical plate. The output shaft of the cylinder passes through the mounting plate and is fixedly connected to the fixing plate 7. When the cylinder is activated, the fixing plate 7 moves horizontally towards the aluminum alloy tube 3. As the adjusting disc 20 contacts the cut surface assembly of the aluminum alloy tube 3, the inclined surface of the aluminum alloy tube 3 causes the adjusting disc 20 to rotate. Under the action of the first spring 23, the two sliding rods 22 will fit tightly against the back of the adjusting disc 20. When the adjusting disc 20 rotates, it causes the two sliding rods 22 to slide relative to the fixing plate 7. The roller 25 at the top slides within the groove of the balance plate 24, causing the balance plate 24 to rotate and become parallel to the working surface of the fixed plate 7. The adjustment unit then drives the cutting blade 6 to rotate. After the angle of the cutting blade 6 is calibrated, the aluminum alloy tube 3 is completely fixed by the clamping assembly. At this point, the cutting plane of the cutting blade 6 is completely parallel to the inclined surface of the aluminum alloy tube 3, preparing for subsequent high-precision cutting. The entire adjustment process does not require manual intervention in angle measurement and adjustment, and the machining reference is automatically established through a purely mechanical structure.

[0044] Furthermore, the adjustment unit includes a tensioning wheel 18 slidably connected to the top of the support base 1 via a linear guide rail, and a second spring 35 connected between the tensioning wheel 18 and the top of the support base 1. A mounting shaft 16 is fixedly mounted at the bottom of the mounting base 5, and the mounting shaft 16 is rotatably connected to the top of the support base 1. A first conveyor wheel 17 is fixedly mounted on the outer wall of the mounting shaft 16. A rotating rod 26 penetrates the top of the support plate 2 and contacts the top of the support base 1. The rotating rod 26 can slide relative to the top of the support base 1 and rotate axially. A second conveyor wheel 19 is fixedly mounted on the part of the rotating rod 26 that penetrates the outer wall of the support plate 2. The first conveyor wheel 17, the tensioning wheel 18, and the second conveyor wheel 19 are connected by a conveyor belt 36.

[0045] See Figure 4 As described above, when the balance plate 24 rotates, it drives the rotating rod 26 to rotate, which in turn drives the second transmission wheel 19, which is fixedly connected to it, to rotate. Therefore, through the cooperation of the second transmission wheel 19 and the conveyor belt 36, the rotational power of the rotating rod 26 can be accurately transmitted to the first transmission wheel 17, thereby driving the mounting shaft 16 to rotate synchronously. This transmission process is achieved through a precisely designed 1:1 speed ratio gear belt, ensuring the accuracy and immediacy of angle transmission. It is worth noting that when the external cylinder drives the fixed plate 7 to move closer to the aluminum alloy tube 3, it also drives the balance plate 24 and the rotating rod 26 to move in the same direction. This movement will cause the center distance between the second transmission wheel 19 and the first transmission wheel 17 to decrease, and the conveyor belt 36 will therefore tend to slack off. At this time, under the preload of the second spring 35, the tension wheel 18 will automatically slide outward along a straight line, thereby compensating for the slack of the conveyor belt 36 in real time and maintaining a constant transmission tension. When the cylinder returns, the second spring 35 pushes the tension wheel 18 to reset, and the system automatically restores the initial tension state. This adaptive design effectively solves the problem of transmission slack caused by moving parts and ensures the reliability of the angle transmission system throughout the entire stroke range.

[0046] In addition, it is worth mentioning that the conveyor belt 36 is made of highly elastic polyurethane material with an elongation of less than 3%, which will not produce plastic deformation during dynamic compensation, thus ensuring the stable operation of the device throughout the process.

[0047] Furthermore, the clamping assembly includes a fixed shaft seat 4 fixedly installed on the top of the support seat 1. A rotating ring 11 is rotatably installed on the inner wall of the fixed shaft seat 4. Several limiting slide rails 14 are fixedly installed on the outer wall of the rotating ring 11. A locking rod 15 is slidably installed on the inner wall of each limiting slide rail 14. The clamping end of each locking rod 15 is provided with an arc surface that matches the outer circle of the aluminum alloy tube 3. A rotatable rotating disk 12 is sleeved on the outer wall of the rotating ring 11. Several first arc grooves 13 are opened on the outer wall of the rotating disk 12 near the limiting slide rail 14. The guide pin of each locking rod 15 passes through the limiting slide rail 14 and forms a sliding fit with the first arc groove 13.

[0048] It also includes a locking part that can selectively restrict the relative axial rotation between the rotating ring 11 and the fixed shaft seat 4.

[0049] See Figure 3 as well as Figure 7 When it is necessary to clamp and fix the aluminum alloy pipe fitting 3, the operator inserts the aluminum alloy pipe fitting 3 horizontally between the two fixed bearing seats 4. At this time, the rotating disk 12 is in the initial unlocked position. Under the combined action of the limiting guide rail 14 and the first arc-shaped groove 13, the guide pin on the locking rod 15 keeps the locking rod 15 away from the aluminum alloy pipe fitting 3, providing sufficient clamping workpiece for the insertion of the aluminum alloy pipe fitting 3. After the aluminum alloy pipe fitting 3 is in place, the operator rotates the rotating disk 12, causing the rotating disk 12 and the rotating ring 11 to rotate relative to each other in the first arc-shaped groove 13 and the limiting guide rail 14. With the combined action of the guide pin on the locking rod 15 and the locking rod 15, multiple locking rods 15 gradually move towards the center. The front end of the locking rod 15 gradually contacts and grips the outer circle of the aluminum alloy tube 3. The external locking assembly locks the rotating disk 12 and the rotating ring 11, forming a uniform and closed axial clamping, thus completing the initial clamping of the aluminum alloy tube 3. Since the rotating ring 11 and the fixed shaft seat 4 are rotatably connected, the aluminum alloy tube 3 can rotate along its own axis to achieve the purpose of making the inclined surface of the aluminum alloy tube 3 completely fit with the working surface of the adjusting disk 20 as described above.

[0050] Furthermore, the locking part includes an inner ring 30 that is rotatably embedded in the outer wall of the fixed shaft seat 4. Several arc-shaped rods 31 are rotatably mounted on the outer wall of the fixed shaft seat 4. Each arc-shaped rod 31 has a second arc-shaped groove 32 on the outer wall of the side near the fixed shaft seat 4. Several second protrusions 33 are fixedly mounted on the outer wall of the inner ring 30, and each second protrusion 33 is slidably mounted in the corresponding second arc-shaped groove 32.

[0051] Furthermore, the top of the fixed shaft seat 4 has a through slot, and a telescopic lever 29 is slidably installed in the slot of the fixed shaft seat 4. The telescopic lever 29 is fixedly connected to the inner ring 30. A third protrusion is fixedly installed on the outer wall of the telescopic lever 29, and a positioning hole is provided on the top of the fixed shaft seat 4 to allow the third protrusion on the telescopic lever 29 to be inserted.

[0052] See Figure 8 as well as Figure 9 When the external cylinder is activated and the working surface of the adjusting disc 20 is fully in contact with the cut surface of the aluminum alloy tube 3, the operator moves the telescopic lever 29 on the top of the fixed shaft seat 4, thereby causing the inner ring 30 to rotate. When the inner ring 30 rotates, the second protrusion 33 slides within the second arc-shaped groove 32. With the cooperation of both, the arc-shaped rod 31 gradually moves closer to the aluminum alloy tube 3. Figure 8As shown, a cylindrical locking block is fixedly installed on the outer wall of the arc-shaped rod 31 and begins to move towards the axis of the aluminum alloy tube 3, forming a progressive locking effect, thereby locking the fixed shaft seat 4 and the rotating ring 11, stopping the rotation of the rotating ring 11. After the operator rotates the telescopic lever 29 to lock the rotating ring 11, the telescopic lever 29 is pressed down, causing the third protrusion on the outer wall of the telescopic lever 29 to insert into the positioning hole at the top of the fixed shaft seat 4 to achieve mechanical self-locking. This design ensures processing stability through a dual locking mechanism (friction locking + mechanical self-locking). The precise cooperation between the cylindrical locking block and the rotating ring 11 completes the complete locking of the rotating ring 11. The "click" tactile feedback and operating force of the third protrusion significantly improve the human-machine interaction experience. The modular locking block design also allows maintenance and replacement to be completed in a short time.

[0053] Furthermore, the rotating disk 12 and the rotating ring 11 can slide relative to each other. The outer wall of the rotating disk 12 is provided with a number of round holes 28, and the outer wall of each limiting slide rail 14 is fixedly installed with a first protrusion 27 that cooperates with the round hole 28.

[0054] See Figure 7 As can be seen from the above, by rotating the rotating disk 12, multiple locking rods 15 can be moved simultaneously toward the axis of the aluminum alloy tube 3 to complete the clamping of the aluminum alloy tube 3. After the aluminum alloy tube 3 is clamped, by moving the rotating disk 12 toward the direction of the limiting guide rail 14, the first protrusion 27 is inserted into the round hole 28 so that the rotating ring 11 and the rotating disk 12 are rotated and locked, preventing the locking rods 15 from disengaging from the aluminum alloy tube 3 in subsequent operations.

[0055] Furthermore, the top of the mounting base 5 is provided with several aluminum chip collection grooves 10, and each aluminum chip collection groove 10 has a chip discharge through hole at the bottom.

[0056] See Figure 2 The circular array of aluminum chip collection tanks 10 significantly improves the cleanliness of the processing environment through innovative structural design. The chip removal through hole at the bottom of each collection tank 10 is connected to the central chip collection system, forming a negative pressure adsorption effect, which allows the aluminum chips generated during the cutting process to quickly slide into the through hole along the inclined side wall of the tank, thereby improving the automatic chip removal efficiency.

[0057] Furthermore, a scale plate 8 is fixedly installed on the top of the support base 1, and a pointing arrow 9 is provided on the outer wall of the mounting base 5. In the initial stage, the pointing arrow 9 points to the zero mark of the scale plate 8.

[0058] The design of the scale plate 8 and the pointing arrow 9 together creates an intuitive angle reference system. The scale plate 8 uses laser-engraved precision scale lines, and together with the tritium-illuminated self-illuminating arrow marks on the outer wall of the mounting base 5, it can still be clearly identified in low-light environments. The initial zero-position calibration function enables the equipment to quickly restore the reference position after restarting, reducing the time for repeated calibration. The operator can judge the angle deviation in real time by observing the offset between the arrow and the scale. Compared with electronic display systems, it has significant advantages such as resistance to electromagnetic interference and no need for power supply, and is particularly suitable for long-term stable use in high-dust industrial environments.

[0059] Furthermore, the top of the mounting base 5 is equipped with a removable protective baffle, which is made of transparent flame-retardant polycarbonate.

[0060] A protective baffle made of transparent flame-retardant polycarbonate is installed on the top of the mounting base 5. While maintaining high light transmittance, it can effectively block instantaneous cutting sparks at high temperatures. Its surface micro-textured treatment can eliminate reflection interference without affecting the observation line of sight. The quick-release buckle structure allows for quick disassembly and assembly, which is convenient for tool replacement and maintenance. The silicone sealing strip on the edge of the baffle can prevent debris from flying and reduce the noise of the equipment operation.

[0061] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
