Description

Technical Field

[0001] This invention relates to the field of aluminum profile technology, specifically to a device for rapidly adjusting the angle of an aluminum profile cutting table saw. Background Technology

[0002] As a key piece of equipment in the aluminum processing field for achieving precise cutting of aluminum profiles, the aluminum profile cutting table saw is typically equipped with a rapid angle adjustment device and a cutting execution mechanism. Among them, the rapid angle adjustment device is a core auxiliary component, used to flexibly adjust the cutting angle according to processing requirements, guiding the cutting workpiece to precisely cut the aluminum profile, adapting to the processing needs of aluminum profiles of different specifications and angles, and ensuring the smooth progress of subsequent assembly, welding and other processes. The core of this rapid angle adjustment device includes a rotary table, a drive mechanism and a cutting component. The angle is adjusted by driving the rotary table to rotate, and it works with the cutting workpiece to complete the cutting operation of the aluminum profile. It is widely used in aluminum profile processing scenarios in the fields of construction, furniture, and electronics.

[0003] Currently, in the cutting process of aluminum profiles, the angle is typically adjusted by setting the 360-degree scale of the rotary table. Once the angle is adjusted, the cutting blade is then controlled to begin cutting. During this process, the cutting workpiece generates high-frequency irregular vibrations at high speed. These vibrations are transmitted to the rotary table through the transmission structure, causing a slight angular deflection and disrupting the initial angle reference. When the deflection angle reaches 0.5° or more, it can cause the cut end face of the aluminum profile to tilt and result in excessive dimensional deviations, severely impacting cutting accuracy and product yield. To address this rotary table angle deflection problem, most existing technologies employ a split-type suspended mounting structure, separately suspending the cutting workpiece and the rotary table, attempting to reduce rotary table angle deflection by weakening the vibration transmission path. However, this type of split-type suspended installation structure has the problem that during the cutting operation, the cutting parts may move circumferentially and disorderly, which will lead to a decrease in the alignment accuracy between the cutting blade and the aluminum profile, resulting in problems such as cutting offset and increased burrs on the cut. This will affect the subsequent cutting effect and processing quality of the aluminum profile and will not meet the requirements of high-precision aluminum profile cutting. Summary of the Invention

[0004] To address the shortcomings of existing technologies, such as the slight angular deflection of the rotary table after continuous operation, this invention proposes a rapid angle adjustment device for aluminum profile cutting table saws.

The second slot is annular in shape. The second slot has 720 conical slots equidistantly arranged along the top circumference to prevent the first ring plate from deflecting slightly. The auxiliary component is fixedly connected to the locking and lifting component and works in conjunction with the slow-cutting component.

[0006] As a further preferred embodiment of this technical solution, the tuning assembly includes a motor, the output end of which is fixedly connected to a rotating shaft, the outer wall of which is fixedly connected to a sleeve rod, the top of which is fixedly connected to a disc, and the outer wall of which is fixedly connected to the inner wall of the first ring plate.

[0007] As a further preferred embodiment of this technical solution, two first electric telescopic rods are fixedly connected to the inner wall of the square shell, and two square holes are opened on the outer wall of the square shell. A plate is fixedly connected to the bottom of each first electric telescopic rod.

[0008] As a further preferred embodiment of this technical solution, one end of the plate is slidably connected to the inner wall of the square hole, a first vertical rod is fixedly connected to the bottom of each plate, and a first slot is provided on the top of the disc.

[0009] As a further preferred embodiment of this technical solution, the slow-cutting component includes a first square plate, the inner wall of which is sleeved on the outer wall of the sleeve rod, a horizontal plate is fixedly connected to one end of the first square plate, a square tube is fixedly connected to the top of the horizontal plate, and four second vertical rods are slidably connected through the top of the horizontal plate.

[0010] As a further preferred embodiment of this technical solution, a second square plate is fixedly connected to the top of the four second vertical rods, and four first compression springs are fixedly connected to the bottom of the second square plate. The bottom end of each first compression spring is fixedly connected to the top of the horizontal plate. A cutting component is fixedly connected to the top of the second square plate, and a second electric telescopic rod is fixedly connected to the bottom of the horizontal plate. A circular ring plate is fixedly connected to the bottom of the second electric telescopic rod, and the bottom of the circular ring plate is rotatably connected to the inner wall of the workbench.

[0011] As a further preferred embodiment of this technical solution, the locking and lifting assembly includes a sleeve plate, the inner wall of which is fixedly connected to the outer wall of the square tube, and a second ring plate is slidably connected to the outer wall of the sleeve plate. Three third vertical rods are respectively slidably connected through the top of the second ring plate.

[0012] As a further preferred embodiment of this technical solution, the bottom of each of the third vertical rods is fixedly connected to the inside of the workbench, and several round rods are respectively slidably connected through the top of the second ring plate.

[0014] As a further preferred embodiment of this technical solution, an airbag is fixedly connected to the top of the horizontal plate, and two bent pipes are respectively connected to the bottom of the airbag. One end of each bent pipe is connected to the inside of the arc-shaped shell, and a one-way valve is connected to the outer wall of each bent pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] Through the coordinated operation of the rotary adjustment assembly, the slow-cutting assembly, the locking and lifting assembly, and the pneumatic auxiliary assembly, the rotary adjustment assembly, relying on 720 graduation marks to form a 0.5° high-precision angle adjustment benchmark, achieves precise graduation control of the first ring plate angle. The slow-cutting assembly, through elastic mechanical guidance, transforms the constraint of chaotic vibration sources from cutting into a single vertical reciprocating motion, blocking the direct rigid transmission of vibration. Combined with the circumferential multi-point conical surface hard-meshing and snapping structure of the locking and lifting assembly's conical block and conical slot hole, the cutting vibration energy is simultaneously utilized to form a pneumatic conversion and adaptive mechanism through the airbag, the bend, and the arc-shaped shell. The pressurized tightening technology overcomes the shortcomings of existing technologies that rely solely on split-body suspension for passive vibration isolation, lack dynamic locking, and are prone to circumferential deviation of the cut parts. It fundamentally avoids the phenomenon of angle deviation caused by cutting vibration disturbance of the first ring plate and disordered circumferential movement of the cut parts. It solves the defects of large dimensional deviation of aluminum profile cutting end face and many burrs on the cut surface, making the aluminum profile cutting angle positioning stable and accurate, the cut surface flat and smooth, and the cutting quality stable and controllable. It meets the application requirements of high-precision aluminum profile multi-angle cutting, and significantly improves the yield rate of aluminum profile cutting and the overall cutting production efficiency.

Detailed Implementation

[0030] 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.

[0031] Please see Figures 1-2 and Figure 6 As shown, the aluminum profile cutting table saw angle quick adjustment device includes: a worktable 100, a square shell 200, a rotary adjustment component 300, a slow cutting component 400, a locking lifting component 500, and an auxiliary component 600. The top of the worktable 100 is provided with a round hole, which is a composite hole of large and small diameters.

[0032] It should be noted that, as Figure 6 As shown, the circular hole is a composite hole of large and small diameters. The circular hole is divided into two half-areas along the circumference. One half of the circumferential area forms a small-diameter semi-circular hole segment, and the other half of the circumferential area forms a large-diameter semi-circular hole segment. The small-diameter semi-circular hole is connected to the bottom of the disc 304, and the large-diameter semi-circular hole is connected to the bottom of the first ring plate 305. When the square hole 307 opened at the bottom of the first ring plate 305 rotates to the large-diameter semi-circular hole, the debris stuck in the inner wall of the square hole 307 can fall off naturally.

[0033] like Figures 1-4 and Figure 6 As shown, the rotary adjustment assembly 300 is located inside the worktable 100 and includes a first ring plate 305. The first ring plate 305 is circular and is arranged at the top center of the worktable 100. The top of the first ring plate 305 is provided with 720 equidistant indexing marks along the circumference.

[0034] The tuning assembly 300 includes a motor 301, the output end of the motor 301 is fixedly connected to a rotating shaft 302, the outer wall of the rotating shaft 302 is fixedly connected to a sleeve rod 303, the top of the rotating shaft 302 is fixedly connected to a disc 304, and the outer wall of the disc 304 is fixedly connected to the inner wall of the first ring plate 305.

[0035] When using, combine Figure 6 As shown, the above-mentioned sleeve rod 303 has a cross-shaped sleeve structure, which is used to pull the first square plate 401 to rotate around the rotating shaft 302.

[0036] like Figure 1 and Figures 4-5 As shown, two first electric telescopic rods 306 are fixedly connected to the inner wall of the square shell 200, and two square holes 307 are opened on the outer wall of the square shell 200. A plate 308 is fixedly connected to the bottom of each first electric telescopic rod 306.

[0037] When using, combine Figure 1 and Figure 5 The tops of the two first electric telescopic rods 306 are respectively fixedly connected to the top sides of the inner wall of the square shell 200. The square hole 307 is used to limit the lifting trajectory of the plate 308. The end of the plate 308 near the first electric telescopic rod 306 has a curved plate structure, and the top of the end away from the first electric telescopic rod 306 has a semi-circular plate structure.

[0038] like Figure 1 and Figures 5-6 As shown, one end of the plate 308 is slidably connected to the inner wall of the square hole 307, and the bottom of each plate 308 is fixedly connected to a first vertical rod 309. The top of the disc 304 is provided with a first slot 310.

[0039] When using, combine Figures 5-6 The top of the first vertical rod 309 is cylindrical, and the bottom is a conical suction cup structure, which is used to press down and position the aluminum profile. The first slot 310 is rectangular in shape, which is used to facilitate the passage of the cutting blade of the cutting part 407 and to cut the aluminum profile.

[0040] like Figures 2-3 and Figure 7 As shown, the slow-cut component 400 can be linked and cooperated with the rotary component 300;

[0041] The slow-cutting component 400 includes a first square plate 401, the inner wall of which is sleeved on the outer wall of the sleeve rod 303. A horizontal plate 402 is fixedly connected to one end of the first square plate 401, and a square tube 403 is fixedly connected to the top of the horizontal plate 402. Four second vertical rods 404 are slidably connected through the top of the horizontal plate 402.

[0042] When using, combine Figure 7 The inner wall of the first square plate 401 is slidably sleeved on the outer wall of the bottom end of the sleeve rod 303, and the first square plate 401 can be pulled to rotate around the rotating shaft 302 by the rotation of the sleeve rod 303.

[0043] like Figure 3 and Figures 7-9 As shown, a second square plate 406 is fixedly connected to the top of the four second vertical rods 404. Four first compression springs 405 are fixedly connected to the bottom of the second square plate 406. The bottom end of each first compression spring 405 is fixedly connected to the top of the horizontal plate 402. A cutting piece 407 is fixedly connected to the top of the second square plate 406. A second electric telescopic rod 408 is fixedly connected to the bottom of the horizontal plate 402. A circular ring plate 409 is fixedly connected to the bottom of the second electric telescopic rod 408. The bottom of the circular ring plate 409 is rotatably connected to the inner wall of the workbench 100.

[0044] When using, combine Figure 3 and Figures 7-9 The four first compression springs 405, through elastic compression, suspend the cutting piece 407 at the top of the second square plate 406 above the horizontal plate 402, reducing the vibration transmission generated when the cutting piece 407 is in operation. Since the ring plate 409 is rotatably connected to the bottom of the inner wall of the worktable 100, when the horizontal plate 402 rotates around the sleeve rod 303, the rotating horizontal plate 402 can pull the second electric telescopic rod 408 and the ring plate 409 to rotate along the bottom of the inner wall of the worktable 100, preventing jamming.

[0045] like Figure 2 and Figure 10 As shown, the locking and lifting assembly 500 is fixedly connected to the slow-cutting assembly 400 and includes a second slot 507. The second slot 507 is opened at the bottom of the first ring plate 305. The second slot 507 is generally in the shape of an annular groove. 720 conical slots are evenly arranged along the top circumference of the second slot 507, which can prevent the first ring plate 305 from deflecting slightly.

[0046] When using, combine Figure 10 The bottom of the second slot 507 is a circular groove structure, and 720 conical slots are evenly distributed around the top of the circular groove. Each conical slot corresponds to one of the aforementioned 720 graduation marks, forming an angle reference with a 0.5° graduation interval, so as to achieve precise alignment and graduation locking of the first ring plate 305 angle.

[0047] like Figure 2 and Figures 8-11As shown, the locking and lifting assembly 500 includes a sleeve plate 501. The inner wall of the sleeve plate 501 is fixedly connected to the outer wall of the square tube 403. A second ring plate 502 is slidably connected to the outer wall of the sleeve plate 501. Three third vertical rods 503 are respectively slidably connected through the top of the second ring plate 502.

[0048] The bottom of each third vertical rod 503 is fixedly connected to the inside of the workbench 100. Several round rods 509 are slidably connected through the top of the second ring plate 502. A cone block 504 is fixedly connected to the top of each round rod 509. A second compression spring 505 is fixedly connected to the bottom of each cone block 504. The bottom of the second compression spring 505 is fixedly connected to the top of the second ring plate 502. An arc plate 506 is fixedly connected to the bottom of the several round rods 509.

[0049] When using, combine Figure 2 and Figures 8-11 The three third vertical rods 503 are used to limit and allow the second ring plate 502 to move vertically up and down along the outer wall of the third vertical rod 503, and to prevent the second ring plate 502 from rotating with the sleeve plate 501. The bottom of each third vertical rod 503 is fixedly connected to the bottom of the inner wall of the worktable 100. The cone block 504 can be precisely aligned with each conical slot and fit tightly. The cone block 504 is squeezed to the inner wall of the conical slot by the elastic compression of the second compression spring 505.

[0050] like Figure 2 and Figure 7 and Figures 10-11 As shown, the auxiliary component 600 is fixedly connected to the locking and lifting component 500 and works in conjunction with the slow-cutting component 400.

[0051] The auxiliary component 600 includes an arc-shaped shell 601, which is fixedly connected to the bottom of the second ring plate 502. The outer wall of the arc-shaped plate 506 is slidably connected to the inner wall of the arc-shaped shell 601. An airbag 602 is fixedly connected to the top of the horizontal plate 402. The bottom of the airbag 602 is connected to two bent pipes 603. One end of each bent pipe 603 is connected to the inside of the arc-shaped shell 601. A one-way valve 604 is connected to the outer wall of each bent pipe 603.

[0052] In use, the airbag 602 is a one-way exhaust self-resetting airbag of the prior art, model SA-200. It can withstand the compression of vibration and allows the airflow inside the airbag 602 to enter the interior of the bend 603, thereby injecting it into the interior of the arc-shaped shell 601. After the airflow inside the airbag 602 is discharged outward, it can slowly and automatically replenish air after exhaust, restoring the initial air pressure and rigidity, facilitating subsequent continuous operation, through the aforementioned one-way valve 6. 04 is used to limit the airflow direction inside the bend 603, so that the airflow can only enter the interior of the arc-shaped shell 601 in one direction. This can prevent the airbag 602 from generating negative pressure during the vibration and lifting of the second square plate 406, which would cause the airflow to flow back in reverse and maintain the stability of the pneumatic locking condition. A pressure relief valve is connected to one side of the bottom of the outer wall of the arc-shaped shell 601. When the air pressure in the area below the arc plate 506 inside the arc-shaped shell 601 is detected to be too high, the pressure relief valve can control the airflow in the area below the arc-shaped shell 601 to automatically relieve pressure.

[0053] Working principle:

[0054] Preparation phase: Combining Figures 1-6 The drive motor 301 drives the rotating shaft 302 and the disc 304 to rotate. The disc 304 drives the first ring plate 305 to rotate. The 720 graduation marks set on the top of the first ring plate 305 form an angle adjustment reference with a graduation accuracy of 0.5°, realizing precise graduation control of the rotation angle. After the angle is adjusted to the right position, the drive motor 301 stops power output and remains locked. The aluminum profile is placed on the top of the disc 304, and one side of the aluminum profile is attached to the side wall of the square shell 200. Then, the first electric telescopic rod 306 is controlled to drive the plate 308 and the first vertical rod 309 to descend. The two first vertical rods 309 press down on the top two sides of the aluminum profile to realize the vertical downward pressing clamping and positioning of the aluminum profile.

[0055] Cutting stage: Combination Figure 3 and Figures 7-9When the aforementioned drive motor 301 rotates, the sleeve rod 303 drives the first square plate 401 to rotate coaxially. The first square plate 401 drives the horizontal plate 402, square tube 403, second vertical rod 404, first compression spring 405, second square plate 406, and cutting piece 407 to rotate around the sleeve rod 303, so that the cutting blade on the cutting piece 407 is always kept in the corresponding position below the first slot 310 opened at the top of the disc 304, forming a cutting alignment reference that changes synchronously with the angle. When the horizontal plate 402 rotates, the horizontal plate 406... 2. Drive the second electric telescopic rod 408 and the annular plate 409 to rotate at the bottom of the inner wall of the worktable 100. When the drive motor 301 is stopped, drive the second electric telescopic rod 408. The second electric telescopic rod 408 indirectly drives the second square plate 406 and the cutting piece 407 to move vertically up and down. At this time, start the cutting piece 407 so that its cutting blade forms a rotating cutting condition. The cutting blade in the rotating working state passes through the first slot 310 upward and performs a penetrating cutting operation on the aluminum profile supported above the disc 304.

[0056] Gradual cutting phase: combined Figures 8-9 When the cutting part 407 is in high-speed operation, it will generate irregular high-frequency vibrations. Due to the sleeve limit of the square tube 403 on the second square plate 406, the square tube 403 can limit the disorderly circumferential displacement of the cutting part 407 above the second square plate 406. At the same time, it is elastically compressed by the four first compression springs 405, which mechanically guides the composite vibration generated by the cutting part 407, so that the chaotic vibration source is constrained and transformed into a single vertical reciprocating motion. The second square plate 406 drives the second vertical rod 404 to slide up and down on the inner wall of the horizontal plate 402, thereby blocking the cutting vibration from being transmitted to the first ring plate 305, avoiding the first ring plate 305 from being disturbed by vibration and causing a small circumferential sway and angular displacement, and ensuring the stability of the positioning accuracy after angle adjustment.

[0057] Lock-up phase: Combined Figure 2 and Figures 8-11When the square tube 403 rises, it drives the sleeve plate 501 and the second ring plate 502 to rise vertically along the outer wall of the third vertical rod 503. The second ring plate 502 drives the round rod 509 and the cone block 504 to rise vertically. During the rise, the cone block 504 gradually enters the second slot 507 opened at the bottom of the first ring plate 305. The tops of each cone block 504 gradually attach and lock onto the inner wall of the conical slot circumferentially arranged at the upper end of the second slot 507. This can distribute and offset the vibration impact and circumferential torsional torque generated during the aluminum profile cutting process, and block the vibration. The transmission of disturbance to the first ring plate 305 effectively avoids the slight circumferential sway and angular deflection of the first ring plate 305 caused by the vibration of aluminum profile cutting. Since the outer wall of the sleeve plate 501 slides on the inner wall of the second ring plate 502, when the sleeve rod 303 drives the square tube 403 and the sleeve plate 501 to rotate, the second ring plate 502 will not rotate. This ensures that the multiple sets of cone blocks 504 are always aligned and stay in the preset position below the large diameter section of the round hole, providing a preset alignment basis for the subsequent accurate alignment and smooth insertion of the cone blocks 504 into the second slot hole 507, and ensuring that the locking and positioning action is reliable and smooth.

[0058] Supplementary phase: Combination Figure 7 and Figure 11 When the cutting blade of the cutting component 407 cuts the aluminum profile, the slight up-and-down vibration generated can drive the second square plate 406 to move vertically up and down along the inner wall of the square tube 403. During the up-and-down process, the second square plate 406 intermittently presses down on the upper end of the airbag 602, squeezing the airbag 602 so that the airflow inside it enters the interior of the arc-shaped shell 601 through the bend 603. The airflow pushes the arc-shaped plate 506 sliding inside the arc-shaped shell 601, causing the arc-shaped plate 506 to drive the round rod 509 and the cone block 504 to move slightly vertically along the inner wall of the arc-shaped shell 601. In this way, the vertical vibration energy generated by cutting is pneumatically converted and mechanically utilized, driving the cone block 504 to always keep it in a close and tight state, so that the cone block 504 is more firmly engaged and locked in the inner wall of the second slot 507, realizing vibration-adaptive tightening and locking, suppressing vibration gap play, and improving the overall stability of the rotary table angle positioning.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
