Description

Technical Field

[0001] This utility model relates to the field of cutting positioning equipment, specifically a cutting angle positioning device. Background Technology

[0002] Current aluminum processing requires cutting equipment, but existing cutting equipment cannot adjust the cutting angle in a timely and rapid manner during the cutting process. Most of them only have a fixed cutting mechanism to process aluminum. If the cutting angle needs to be adjusted, the staff needs to manually move the aluminum, which increases the risk of injury to the staff and increases their workload.

[0003] According to the patent document CN219562270U, ​​a cutting angle positioning structure for aluminum profile processing is disclosed. It includes a cutting table with symmetrically arranged limit plates on both sides of its upper end. A connecting seat is installed in the middle of the outer side of each limit plate, and the connecting seat is sleeved on the outer side of a rotating rod. Support plates are installed in the middle of the upper end of each limit plate, and a horizontal plate is arranged between the support plates. An electric hydraulic cylinder is installed in the middle of the lower end of the horizontal plate, and a pressure block is threaded onto the output end of the electric hydraulic cylinder. In use, the limit plates facilitate clamping and fixing of the aluminum plate on both sides. Then, the electric hydraulic cylinder installed in the lower end of the horizontal plate in the middle of the support plate drives the pressure block to descend, facilitating the limiting of the upper end of the aluminum material, thereby improving the positioning accuracy of the aluminum material and preventing deviation during cutting, thus improving cutting accuracy. However, while this solution achieves fixation during cutting, it cannot collect the generated debris, which is inconvenient in use. Utility Model Content

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1 to 6 This utility model provides a technical solution: a cutting angle positioning device, including a fixed base 1, a limiting groove 2 on the fixed base 1, a fixing groove 3 between the limiting grooves 2, and a support assembly 4 movably installed between the fixing groove 3 and the limiting groove 2. The support assembly 4 includes a movable plate 12, a limiting block 13 and a threaded seat 14 are respectively fixed to the bottom of the movable plate 12, the threaded seat 14 is movably installed inside the fixing groove 3, the limiting block 13 is movably installed inside the limiting groove 2, and a fixing lug 17 is welded to the movable plate 12. A connecting rod 18 is rotatably mounted between the fixed lugs 17. A support plate 8 is welded onto the fixed seat 1. A support seat 9 is fixed between the support plates 8. A drive motor 5 is fixedly mounted on the side of the fixed seat 1. A threaded post 15 is mounted on the drive motor 5. The threaded post 15 is rotatably mounted on the threaded seat 14. A support lug 19 is rotatably mounted on one end of the connecting rod 18. The drive motor 5 drives the threaded post 15 to rotate. The rotation of the threaded post 15 on the threaded seat 14 drives the threaded seat 14 to move back and forth. The back and forth movement of the threaded seat 14 drives the movement of the movable plate 12.

[0019] In this embodiment, a motor base 20 is fixed to one end of the support lug 19. A servo motor 24 is fixed to the bottom inner wall of the motor base 20, and a saw blade 22 is fixed to the servo motor 24. A slot is opened on the motor base 20, and the saw blade 22 is rotatably installed inside the slot. The motor base 20 is installed inside the support base 9 through a rotating shaft 21. A cavity is opened inside the support base 9. A connecting box 10 is fixedly installed on the support base 9, and an exhaust fan is fixed to the top of the connecting box 10. An extrusion assembly 11 is movably installed on the support base 9. The extrusion assembly 11 includes a fixed column 32. A fixing hole is opened on the support base 9, and the fixed column 32 is movably installed inside the fixing hole. A buffer mechanism 33 is movably installed on the fixed column 32. The buffer mechanism 33 is a buffer spring. When the fixed column 32 moves downward, the limiting plate 34 squeezes and contracts the buffer mechanism 33. After the extrusion plate loses its extrusion force, the rebound force of the buffer mechanism 33 pushes the fixed column 32 to move upward and return to its original position.

[0020] In this embodiment, a limit plate 34 is fixed to one end of the buffer mechanism 33 and the fixed column 32, and the other end of the buffer mechanism 33 is fixed to the top of the support base 9. A positioning plate 28 is fixed to one end of the fixed column 32, and a pressing plate 29 is slidably installed on the bottom of the positioning plate 28. A protrusion 30 is fixed to the top of the pressing plate 29, and the protrusion 30 is installed on the bottom of the positioning plate 28 through a reset mechanism 31. A positioning tube 25 is fixed on the motor base 20, and a positioning column 26 is movably installed inside the positioning tube 25. One end of the positioning column 26 contacts the positioning plate 28 through a ball bearing. A support mechanism 27 is fixed between the column 26 and the positioning tube 25. An opening is opened on the fixed seat 1, and a fixed box 6 is fixed at the bottom of the opening. A movable box 7 is movably installed inside the fixed box 6. A filter plate 35 is fixed on the movable box 7. A stop block 36 and an exhaust fan 37 are fixed inside the fixed box 6. The stop block 36 is movably installed at the bottom of the filter plate 35. Both the reset mechanism 31 and the support mechanism 27 are springs. When the extrusion plate 29 moves left and right, the protrusion 30 moves inside the groove and presses against the reset mechanism 31. After the extrusion plate 29 is released, the extrusion plate 29 horizontally drives the material to move back to its original position.

[0021] Working principle: When in use, the material is placed on the top of the fixed base 1 and the bottom of the extrusion assembly 11. The drive motor 5 is started to drive the threaded column 15 to rotate. After the threaded column 15 rotates on the threaded seat 14, it drives the movable plate 12 to move. The movable plate 12 moves the lower limit block 13 inside the limit groove 2. The limit groove 2 and the limit block 13 cooperate to ensure the horizontal and vertical movement of the movable plate 12. After the movable plate 12 moves, the connecting rod 18 rotates on the fixed hanging ear 17. The other end of the connecting rod 18 rotates on the support hanging ear 19. The rotation causes the support hanging ear 19 to drive the motor base 20 to tilt on the inner wall of the support base 9 through the rotating shaft 21. The tilt of the motor base 20 adjusts the tilt angle of the saw blade 22. After the saw blade 22 tilts, it is distributed on the side of the material. When one end of the motor base 20 is tilted, one end of the positioning column 26 contacts the positioning plate 28. The positioning plate 28 moves downward through the fixed column 32 under support. After the positioning plate 28 moves downward, the extrusion plate 29 contacts the top of the material. The base 20 continues to tilt and descend. The positioning column 26 compresses and retracts into the positioning tube 25 by squeezing the support mechanism 27. As the positioning column 26 retracts, the squeezing pressure becomes heavier and heavier. The barrel positioning column 26 completes the squeezing and fixing of the material at the bottom of the squeezing plate 29. After the material is squeezed and fixed, the saw blade 22 moves into place. The user holds the material and pushes it at the bottom of the squeezing plate 29. The material and the squeezing plate 29 move together. The material moves to the saw blade 22 for cutting. During cutting, the exhaust fan on the connecting box 10 blows air downwards, and the exhaust fan 37 draws air downwards. The airflow carries the debris into the top of the filter plate 35. After cutting, the movable box 7, which has been collecting debris for a long time, is pulled out for cleaning. The drive motor 5 is started to reverse. The threaded column 15 pushes the threaded seat 14 to move in the opposite direction. After the threaded seat 14 moves in the opposite direction, the movable plate 12 pushes the connecting rod 18 to rotate and tilt back into place. When in place, the motor base 20 retracts into the support base 9. The squeezing assembly 11 loses the squeezing pressure, making it easy to disassemble and move the material.
