Description

Technical Field

[0001] This utility model belongs to the field of adjustable saw blade technology, and in particular relates to a saw blade structure that can be adjusted at multiple angles. Background Technology

[0002] Traditional saw blade angle adjustment relies heavily on manual operation, resulting in low efficiency and poor precision, which affects processing quality. Existing technologies sometimes employ a vertical axis drive to achieve saw blade angle conversion, which can perform both transverse and longitudinal cuts, but suffers from structural complexity and large size. Furthermore, using multiple saw blades in combination can lead to poor heat dissipation and maintenance difficulties. Therefore, developing a compact, flexible, and stable heat dissipation-maintaining multi-angle saw blade structure has become an industry requirement.

[0003] Existing technology CN110153745A discloses a stable and multi-angle adjustable alloy saw blade processing fixture, comprising a base, a limit plate fixedly mounted on the top of the base, a support plate fixedly mounted on the top of the base, a movable seat movably mounted on the top of the support plate, a hydraulic cylinder movably mounted inside the base extending to the top of the base, a connecting rod fixedly mounted on the top of the hydraulic cylinder at the bottom of the movable seat, limit rods fixedly mounted on both sides of the movable seat penetrating the limit plate and extending to the side of the limit plate away from the movable seat, a motor fixedly mounted inside the movable seat, and a first fixed plate fixedly mounted on the top of the movable seat at the output shaft of the motor. This stable and multi-angle adjustable alloy saw blade processing fixture allows for adjustment of the angle of the alloy saw blade, making it easier for users to use in different situations.

[0004] While the above method allows for minute adjustments to the saw blade angle, it only adjusts the blade angle. Over long-term use, this can lead to the saw blade breaking apart, thus requiring improvement.

[0005] Based on this, the present invention designs a saw blade structure with multi-angle adjustment to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that although the saw blade can be adjusted to a small angle, it can only adjust the angle of the saw blade, which will cause the saw blade to break after long-term use. Therefore, a multi-angle adjustable saw blade structure is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A multi-angle adjustable saw blade structure includes a workbench, a rotating platform fixedly mounted on the top of the workbench, a moving groove inside the rotating platform, a first mounting plate slidably mounted on the top of the rotating platform, multiple adjusting studs on both sides of the first mounting plate corresponding to the positions of the moving grooves, an adjusting frame fixedly mounted on the top of the first mounting plate, first fixed slide rails fixedly mounted on both sides of the top of the adjusting frame, a double-ended nut fixedly mounted on one side of the adjusting frame, a double-ended threaded rod rotatably mounted inside the double-ended nut, a moving block slidably mounted on the surface of the double-ended threaded rod, a first support frame fixedly mounted on the top of the moving block, sliding grooves on both sides of the first support frame sliding on the surface of the first fixed slide rails, a connecting frame fixedly mounted on one side of the adjusting studs, and a connecting bearing rotatably connected to one end of the double-ended threaded rod.

[0008] As a further description of the above technical solution: A support plate is fixedly installed on the top of the first support frame, and a second support frame is fixedly installed at multiple points on the top of the support plate. A servo motor is fixedly installed in the middle of the second support frame, and a drive shaft is provided at one end of the servo motor.

[0009] As a further description of the above technical solution: An elastic crank block is fitted onto the surface of the drive shaft. A spring is provided at the bottom of the elastic crank block, and one end of the spring is connected to one end of the support plate.

[0010] As a further description of the above technical solution: A movable plate is fixedly installed on the top of the support plate, a connecting rod pin is rotatably installed inside the movable plate, and a second fixed slide rail is fixedly installed on the top of the movable plate.

[0011] As a further description of the above technical solution: One end of the connecting rod pin is connected to a connecting sleeve shaft, and a connecting rod is sleeved on the surface of the connecting rod pin. One end of the connecting rod is provided with a protruding pin, and the protruding pin passes through one end of the transmission shaft to connect the connecting rod to the transmission shaft.

[0012] As a further description of the above technical solution: The surface of the protruding pin is provided with a movable slider on one side corresponding to the movable plate. The movable slider has a transmission groove inside, and the position of the transmission groove corresponds to the position of the connecting rod pin. A third fixed slide rail is fixedly installed on one side of the movable slider, and the third fixed slide rail slides on the surface of the second fixed slide rail.

[0013] As a further description of the above technical solution: A mounting base is fixedly installed on one side of the movable plate, and a rotating coupling is rotatably installed on one side of the connecting sleeve shaft corresponding to the interior of the mounting base. An auxiliary ring is sleeved on one side of the rotating coupling shaft, and multiple sliding balls are provided inside the auxiliary ring corresponding to the surface of the rotating coupling shaft.

[0014] As a further description of the above technical solution: A third support frame is fixedly installed on one side of the auxiliary ring, a second mounting plate is fixedly installed on the top of the third support frame, a motor is fixedly installed on the top of the second mounting plate, a cutting machine is installed on one side of the motor via a belt, and one side of the cutting machine is fixedly installed on one side of the third support frame.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, a design architecture combining a rotating platform, a moving groove, and adjusting studs is adopted. The device is installed on the top of the rotating platform, and two adjusting studs pass through the first mounting plate and are embedded in the moving groove. Horizontal adjustment is achieved by tightening or loosening the nuts. A strong static friction force can be formed between the rotating platform and the first mounting plate. This friction force can effectively resist the huge torsional force and vibration generated during cutting, ensuring zero drift and no shaking of the set angle during the cutting process. This structure has significant advantages such as simple design, excellent reliability, and low maintenance cost.

[0016] 2. In this utility model, a combination design of servo motor, elastic crank block and connecting rod pin is adopted. The servo motor at the top of the support plate drives the connecting rod to move in a curved manner through the transmission shaft. With the help of the connecting rod pin, the moving slider slides on the top of the second fixed slide rail. The servo motor achieves high-precision angle control with the help of encoder, which can accurately rotate the cutting machine to the target angle, with a precision far exceeding that of manual operation. The transmission groove is connected to the connecting sleeve shaft through the connecting rod pin. When the moving slider slides, it drives the rotating shaft to rotate in the mounting base, thereby causing the second mounting plate and the connected cutting machine to rotate. This design can easily overcome the static friction and load of the rotating platform, save effort in angle adjustment, eliminate the need for a high-power motor, and effectively reduce costs and energy consumption.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see the appendix Figure 1 - Appendix Figure 8This utility model provides a technical solution: a saw blade structure with multi-angle adjustment, including a workbench 1, a rotating platform 2 fixedly installed on the top of the workbench 1, a moving groove 3 opened inside the rotating platform 2, a first mounting plate 4 slidably installed on the top of the rotating platform 2, multiple adjusting studs 5 on both sides of the first mounting plate 4, and the positions of the adjusting studs 5 corresponding to the positions of the moving grooves 3, an adjusting frame 6 fixedly installed on the top of the first mounting plate 4, a first fixed slide rail 7 fixedly installed on both sides of the top of the adjusting frame 6, a double-sided nut 8 fixedly installed on one side of the adjusting frame 6, a double-sided threaded rod 9 rotatably installed inside the double-sided nut 8, a moving block 10 slidably installed on the surface of the double-sided threaded rod 9, a first support frame 11 fixedly installed on the top of the moving block 10, a sliding groove 12 opened on both sides of the first support frame 11, and the sliding groove 12 slides on the surface of the first fixed slide rail 7, a connecting frame 13 fixedly installed on one side of the adjusting studs 5, and a connecting bearing 14 rotatably connected to one end of the double-sided threaded rod 9.

[0020] The specific implementation method is as follows: a support plate 15 is fixedly installed on the top of the first support frame 11, and a second support frame 16 is fixedly installed at multiple points on the top of the support plate 15. A servo motor 17 is fixedly installed in the middle of the second support frame 16, and a drive shaft 18 is provided at one end of the servo motor 17.

[0021] By setting up a servo motor 17 and a drive shaft 18, the device achieves ultimate flexibility and efficiency through program control, and enhances safety through human-machine separation. The servo motor 17 has a built-in high-resolution encoder, and its rotation angle is precisely controlled by the controller. The servo motor 17 drives the drive shaft 18 to transmit forward force.

[0022] The specific implementation method is as follows: an elastic crank block 19 is sleeved on the surface of the drive shaft 18, and a spring 20 is provided at the bottom of the elastic crank block 19, and one end of the spring 20 is connected to one end of the support plate 15.

[0023] By setting up an elastic crank block 19 and a spring 20, the torque generated during the operation of the servo motor 17 is connected to the spring 20 through the elastic crank block 19. The spring 20 always provides a preload to the elastic crank block 19, so that the transmission surface inside it is always in close contact with the mating surface, thereby absorbing shock and vibration and improving the life of the device.

[0024] The specific implementation method is as follows: a movable plate 21 is fixedly installed on the top of the support plate 15, a connecting pin 22 is rotatably installed inside the movable plate 21, and a second fixed slide rail 23 is fixedly installed on the top of the movable plate 21.

[0025] By setting a connecting pin 22 and a second fixed slide rail 23, when the servo motor 17 is running, it is connected to the connecting rod 25 through the transmission shaft 18. When the connecting rod 25 moves in a curve, it drives the connecting pin 22 to move, and drives the moving slider 27 to slide on the surface of the second fixed slide rail 23 to adjust the angle.

[0026] The specific implementation method is as follows: one end of the connecting pin 22 is connected to the connecting sleeve shaft 24, the surface of the connecting pin 22 is fitted with a connecting rod 25, one end of the connecting rod 25 is provided with a protruding pin 26, and the protruding pin 26 passes through one end of the transmission shaft 18 to connect the connecting rod 25 to the transmission shaft 18.

[0027] By setting the connecting pin 22 and the protruding pin 26, the device connects the connecting sleeve shaft 24 to the connecting pin 22, and the transmission shaft 18 is sleeved on one end of the connecting rod 25 through the protruding pin 26 at one end of the connecting rod 25. When the servo motor 17 is running, the force is transmitted through the connecting rod 25, which drives the connecting sleeve shaft 24 at one end of the connecting pin 22 to rotate. When the connecting sleeve shaft 24 rotates, it drives the rotating coupling shaft 31 inside the mounting base 30 to rotate, so as to adjust the angle of the cutting machine 37.

[0028] The specific implementation method is as follows: a movable slider 27 is provided on the surface of the protruding pin 26 corresponding to one side of the movable plate 21. A transmission groove 28 is provided inside the movable slider 27, and the position of the transmission groove 28 corresponds to the position of the connecting rod pin 22. A third fixed slide rail 29 is fixedly installed on one side of the movable slider 27, and the third fixed slide rail 29 slides on the surface of the second fixed slide rail 23.

[0029] By setting the second fixed slide rail 23 and the third fixed slide rail 29, when the servo motor 17 runs, it drives the connecting rod 25 to move in a curve. When the connecting rod 25 moves, it pushes the connecting pin 22 to slide, so as to drive the third fixed slide rail 29 at one end of the moving slider 27 to slide on the surface of the second fixed slide rail 23, so as to counteract the strong torque brought by the servo motor 17 and make the sliding smooth when adjusting the angle of the cutting machine 37.

[0030] The specific implementation method is as follows: a mounting base 30 is fixedly installed on one side of the movable plate 21, and a rotating coupling 31 is rotatably installed on one side of the connecting sleeve shaft 24 corresponding to the inside of the mounting base 30. An auxiliary ring 32 is sleeved on one side of the rotating coupling 31, and multiple sliding balls 33 are provided inside the auxiliary ring 32 corresponding to the surface of the rotating coupling 31.

[0031] By setting a rotating coupling 31 and an auxiliary ring 32, when the connecting sleeve shaft 24 drives the rotating coupling 31 at one end to rotate, the rotating coupling 31 drives multiple sliding balls 33 to slide inside the auxiliary ring 32, so as to assist the rotating coupling 31 to rotate smoothly.

[0032] The specific implementation method is as follows: a third support frame 34 is fixedly installed on one side of the auxiliary ring 32, a second mounting plate 35 is fixedly installed on the top of the third support frame 34, a motor 36 is fixedly installed on the top of the second mounting plate 35, a cutting machine 37 is installed on one side of the motor 36 via a belt, and one side of the cutting machine 37 is fixedly installed on one side of the third support frame 34.

[0033] By setting a third support frame 34 and a second mounting plate 35, and fixing the third support frame 34 to the top of the mounting base 30, when the rotating shaft 31 rotates, it drives the second mounting plate 35 at the top to rotate, and at the same time drives the third support frame 34 to rotate, so that the cutting machine 37 rotates synchronously, and the angle of the cutting machine 37 is adjusted.

[0034] Working principle and usage: First, smoothly push the workbench 1 to the designated position to prepare for subsequent operations. Next, accurately place the raw material to be cut on the cutting rack to ensure that the raw material is placed stably. Then, adjust the horizontal angle of the device. Specifically, loosen multiple adjusting studs 5 to release the fixing restriction on the first mounting plate 4, and then push the first mounting plate 4 to move it flexibly in the moving groove 3 until the device reaches the required horizontal angle. After the horizontal angle adjustment is completed, adjust the front and rear distance. Start the motor connected to one end of the connecting bearing 14. The motor drives the bidirectional threaded rod 9 to rotate inside the bidirectional nut 8. Since there is a specific transmission relationship between the bidirectional threaded rod 9 and the moving block 10, the rotation of the bidirectional threaded rod 9 will drive the moving block 10 to move forward or backward, thereby adjusting the device to the appropriate front and rear distance. After the front and rear distances are properly adjusted, precise angle adjustment is performed. At this time, the servo motor 17 is started. The servo motor 17 has a precise programming program pre-set inside. After the servo motor 17 is started, it drives the transmission shaft 18 to rotate synchronously. The transmission shaft 18 is like a reliable torque transmission bridge, accurately transmitting the torque generated by the servo motor 17 to the inside of the connecting rod 25. Under the action of torque, the connecting rod 25 begins to move in a curve, which in turn drives the connecting pin 22 to move accordingly. During the movement, the connecting pin 22 will cause the third fixed slide rail 29 at one end of the moving slider 27 to slide smoothly along the surface of the second fixed slide rail 23. Through this ingenious transmission and sliding mechanism, the device can achieve smooth and precise angle adjustment. The connecting pin 22 and the connecting sleeve shaft 24 are firmly connected, forming a reliable mechanical transmission node. When the connecting sleeve shaft 24 starts to rotate, the rotational power it generates is precisely transmitted to the rotating shaft 31, driving the rotating shaft 31 to rotate synchronously. During the rotation, one end of the rotating shaft 31 is cleverly placed inside the auxiliary ring 32 and slides along the inner wall of the auxiliary ring 32. The auxiliary ring 32 plays a key guiding and stabilizing role, effectively ensuring the smoothness of the rotating shaft 31 during the rotation process and avoiding shaking or jamming caused by uneven rotation. As the rotating shaft 31 continues to rotate, its power is further transmitted to the third support frame 34, causing the third support frame 34 to rotate around a predetermined axis. Since the cutting machine 37 is firmly fixed on the third support frame 34, the rotation of the third support frame 34 will synchronously drive the cutting machine 37 to rotate, thereby achieving precise adjustment of the angle of the cutting machine 37 and meeting the angle requirements under different cutting scenarios.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
