[0017] 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.
[0018] Specific implementation examples are given below.
[0019] like Figure 1-5As shown, a small milling machine includes a milling machine body 1. A cutting device 11 is slidably connected to the side wall of the milling machine body 1, and a control panel 12 is installed at the end of the cutting device 11. A support table 13 is fixedly connected to the top of the milling machine body 1. A rotating shaft 14 is rotatably connected to one side of the support table 13. A placement table 15 is fixedly connected to the outer wall of the rotating shaft 14. A support base 16 is fixedly connected to the side wall of the control panel 12. A first connecting frame 17 is fixedly connected to the end of the support base 16. A second connecting frame 18 is fixedly connected to the bottom of the first connecting frame 17. Two mounting parts 19 are fixedly connected to the top of the second connecting frame 18. Rotating wheels 110 are rotatably connected to the inner walls of the two mounting parts 19. The rotating wheels 110 are located at the bottom of the placement table 15. The rotating wheels 110 are located away from the rotating shaft 14. When the cutting device 11 is in the middle or lower gear position, the placement table 15 can be placed flat on the top of the support table 13 under the action of gravity, and the workpiece can be placed. During daily workpiece processing, the cutting device 11 is on the milling machine body. The middle and lower stops of the side wall slide to cut the workpiece on the placement table 15. When the workpiece is finished and there are residual processing residues in the inner groove of the placement table 15, the cutting device 11 is moved to the upper stop by the control panel 12. At this time, the support base 16 moves up synchronously with the cutting device 11, which drives the first connecting frame 17 and the second connecting frame 18 to move up, so that the rotating wheel 110 in the mounting part 19 contacts the bottom of the placement table 15 and pushes the placement table 15 to rotate around the rotating shaft 14, so that the placement table 15 is tilted. The residue on the top slides down and is transferred under the action of gravity. After cleaning, the cutting device 11 moves back to the middle and lower stops, and the placement table 15 is placed flat on the top of the support table 13 under the action of gravity, restoring the workpiece placement state. This step solves the problem of residues accumulating in the inner groove of the placement table 15 after processing by a small milling machine. No additional cleaning tools are required. The automatic tilting and cleaning of the placement table 15 can be achieved simply by switching the stops of the cutting device 11, which simplifies the cleaning process, improves the efficiency of post-processing cleaning, and does not affect the continuity of normal processing.
[0020] like Figure 1-5As shown, the milling machine body 1 has a placement groove 2 on its side wall. A mounting plate 21 is fixed to the inner wall of the placement groove 2. An electric actuator 22 is mounted on the inner wall of the mounting plate 21. A top plate 23 is fixed to the output shaft of the electric actuator 22. The top plate 23 is located at the bottom of the placement table 15 and is positioned near the rotating shaft 14. A support member 24 is fixed to the side wall of the milling machine body 1. A sliding column 25 is slidably connected to the end of the support member 24. A limit piece 26 is fixed to the top of the sliding column 25. A pressure sensor 27 is mounted at the bottom of the sliding column 25. The pressure sensor 27 is located on the top of the support base 16. Both the pressure sensor 27 and the electric actuator 22 are electrically connected to the control panel 12. When the cutting device 11 moves to the upper gear, the top of the support base 16 contacts the pressure sensor 27. After sensing the pressure, the pressure sensor 27 sends an electrical signal to the control panel 12. The control panel 12 controls the electric actuator 22 on the mounting plate 21 in the placement groove 2 to output... The axial retraction causes the top plate 23 to detach from the bottom of the placement table 15. The cutting device 11 continues to move upward, and the rotating wheel 110 lifts the end of the placement table 15 away from the rotating shaft 14, causing the placement table 15 to tilt. When the cutting device 11 moves back to the middle or lower position, the support seat 16 disengages from the pressure sensor 27. The pressure sensor 27 sends a signal to cause the electric push rod 22 to extend axially upward. The top plate 23 then lifts the bottom of the placement table 15 again, maintaining the stability of the placement table 15 when it is flat. At the same time, the sliding column 25 and the limiting piece 26 on the support 24 can limit the sliding range of the pressure sensor 27, improving the structural stability. This step solves the stability problem of the placement table 15 during tilting cleaning and resetting to flat position. Through the linkage between the pressure sensor 27 and the electric push rod 22, the lifting and lowering of the top plate 23 is automatically controlled, ensuring that the placement table 15 can tilt smoothly during cleaning and stably support the placement table 15 during processing, avoiding the shaking of the placement table 15 from affecting the processing accuracy and improving the reliability of the equipment operation.
[0021] like Figure 1-5 As shown, the inner wall of the placement platform 15 has two movable grooves 3, and the ends of the movable grooves 3 have arc grooves 31. The movable grooves 3 are inclined inside the placement platform 15, and impact balls 32 are slidably arranged on the inner wall of the movable grooves 3. When the placement platform 15 is flat, the movable grooves 3 inside it are in an inclined state. Under the action of gravity, the impact balls 32 roll to the end of the arc groove 31 away from the rotating shaft 14. When the placement platform 15 is tilted around the rotating shaft 14, the tilt direction of the movable grooves 3 changes, and the impact balls 32 roll rapidly downward along the movable grooves 3 under the action of gravity, impacting the inner wall of the movable grooves 3 and generating vibration. This step solves the problem of low efficiency of residue sliding off by gravity when the placement platform 15 is tilted. The impact vibration of the impact balls 32 can make the residue attached to the surface of the placement platform 15 easier to fall off, speed up the residue discharge speed, improve the cleaning effect, and reduce residue.
[0022] like Figure 1-5As shown, a connecting block 4 is fixedly connected to the end of the placement platform 15. A universal ball 41 is rotatably connected to the inner wall of the connecting block 4. An elastic rope 42 is fixedly connected to the end of the universal ball 41. The elastic rope 42 is fixedly connected to the milling machine body 1. When the placement platform 15 tilts and rises around the rotating shaft 14, the connecting block 4 at the end of the placement platform 15 rotates with the placement platform 15. The universal ball 41 in the connecting block 4 drives the elastic rope 42 to stretch. The elastic rope 42 generates elastic tension. When the cutting device 11 moves down and the rotating wheel 110 disengages from the bottom of the placement platform 15, the elastic tension of the elastic rope 42 assists the placement platform 15 to rotate and reset around the rotating shaft 14. Combined with gravity, the placement platform 15 is quickly leveled. This step solves the problem that the placement platform 15 is slow to reset and may jam when relying solely on gravity. The tension of the elastic rope 42 assists in the reset, making the reset of the placement platform 15 smoother and improving the overall work efficiency by reducing the time spent switching between cleaning and processing states.
[0023] like Figure 1-5 As shown, the support base 16 has a slot 5 at its end. The first connecting frame 17 and the slot 5 are engaged. The first connecting frame 17 is fixed to the inner wall of the slot 5 by two bolts 51. When maintenance or replacement of components such as the first connecting frame 17, the second connecting frame 18, and the rotating wheel 110 is required, the two bolts 51 in the slot 5 of the support base 16 are unscrewed to remove the first connecting frame 17 from the slot 5, thus completing the disassembly. After maintenance, the first connecting frame 17 is inserted into the slot 5 and the bolts 51 are tightened to fix it, thus restoring the installation. This step solves the problem of inconvenient disassembly and maintenance of the connecting frame assembly. The engaging design of the slot 5 improves the stability of the first connecting frame 17 during operation, and the detachable design of the bolts 51 facilitates later maintenance, reducing the difficulty and time cost of equipment maintenance.
[0024] like Figure 1-5 As shown, a gasket 6 is fixed to the top of the support base 16. When the support base 16 moves upward and contacts the pressure sensor 27, the gasket 6 on the top of the support base 16 is located between the support base 16 and the pressure sensor 27, buffering the direct contact between the two. This step solves the problem that the support base 16 and the pressure sensor 27 are prone to wear and tear due to long-term contact, which affects the sensing accuracy. The protective function of the gasket 6 extends the service life of the pressure sensor 27 and the support base 16, ensures the accuracy of pressure sensing, and improves the durability and reliability of the equipment.
[0025] Working principle: During routine workpiece processing, the cutting device 11 slides in the middle and lower gears on the side wall of the milling machine body 1 to cut the workpiece on the placement table 15. When processing residue remains in the groove of the placement table 15 after processing, the cutting device 11 is moved to the upper gear via the control panel 12. At this time, the support base 16 moves upward synchronously with the cutting device 11, driving the first connecting frame 17 and the second connecting frame 18 to move upward, so that the rotating wheel 110 in the mounting part 19 contacts the bottom of the placement table 15, pushing the placement table 15 to rotate around the rotating shaft 14, causing the placement table 15 to tilt. The residue on the top slides down and is transferred under the action of gravity. After cleaning, the cutting device 11 moves back to the middle and lower gears, and the placement table 15 is placed flat under the action of gravity. The top of the support platform 13 returns to the workpiece placement state. When the cutting device 11 moves to the upper gear, the top of the support base 16 contacts the pressure sensor 27. After sensing the pressure, the pressure sensor 27 sends an electrical signal to the control panel 12. The control panel 12 controls the electric push rod 22 on the mounting plate 21 in the placement slot 2 to retract axially downwards, causing the top plate 23 to disengage from the bottom of the placement platform 15. The cutting device 11 continues to move upwards, and the rotating wheel 110 lifts the end of the placement platform 15 away from the rotating shaft 14, causing the placement platform 15 to tilt. When the cutting device 11 moves back to the middle or lower gear, the support base 16 disengages from the pressure sensor 27. The pressure sensor 27 sends a signal to extend the electric push rod 22 axially upwards, and the top plate 23 lifts the bottom of the placement platform 15 again, maintaining the placement platform 15. The stability when the platform is flat is improved. Meanwhile, the sliding column 25 and limiting piece 26 on the support 24 limit the sliding range of the pressure sensor 27, enhancing structural stability. When the platform 15 is flat, its internal movable groove 3 is tilted. The impact ball 32 rolls under gravity to the end of the arc groove 31 away from the rotating shaft 14. When the platform 15 tilts around the rotating shaft 14, the tilt direction of the movable groove 3 changes, and the impact ball 32 rolls rapidly downwards along the movable groove 3 under gravity, vibrating upon impacting the inner wall of the movable groove 3. When the platform 15 tilts and tilts around the rotating shaft 14, the connecting block 4 at the end of the platform 15 rotates with the platform 15. The universal ball 41 inside the connecting block 4 drives the elastic rope 42 to stretch, generating elastic tension. When the cutting device 11 moves down and the rotating wheel 110 disengages from the bottom of the placement platform 15, the elastic tension of the elastic rope 42 assists the placement platform 15 to rotate around the rotating shaft 14 and reset. Combined with gravity, the placement platform 15 is quickly placed flat. When it is necessary to maintain or replace components such as the first connecting frame 17, the second connecting frame 18, and the rotating wheel 110, the two bolts 51 in the slot 5 of the support base 16 are unscrewed to remove the first connecting frame 17 from the slot 5, thus completing the disassembly. After maintenance, the first connecting frame 17 is inserted into the slot 5 and the bolts 51 are tightened to fix it, thus restoring the installation. When the support base 16 moves up and contacts the pressure sensor 27, the pad 6 on the top of the support base 16 is located between the support base 16 and the pressure sensor 27 to buffer the direct contact between the two.
