The equipment used for robotic polishing mainly includes flexible mechanical polishing heads, flexible belt polishing heads, and flexible airbag polishing heads to achieve the flexible polishing effect of robots.

[0003] Since the polishing process of workpieces now often requires robotic polishing operations, and different workpieces require different polishing heads, and even the same workpiece requires switching between polishing heads of different precision, the process of changing polishing heads is quite cumbersome, which has brought certain adverse effects to actual use. Therefore, improvements are needed. Utility Model Content

This invention uses a driving robotic arm as the basic control for adjusting the position of the flexible polishing head, and performs reversing switching of multiple flexible polishing heads of different specifications on a reversing plate. It also ensures the stable positioning of the flexible polishing head after reversing and the effective blowing and chip removal operation, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

One end of the driving robotic arm is rotatably connected to a clamping frame via a driving end. A swinging clamping plate is rotatably connected to the inside of the clamping frame via a driving end. A connecting rod is magnetically attached to the surface of the swinging clamping plate, and a locking screw is connected between the surface of the connecting rod and the surface of the swinging clamping plate via an internal thread groove. A stable base is fixedly connected to one end of the connecting rod. A servo motor is fixedly mounted inside the stable base.

[0009] Furthermore, one end of the connecting pole is fixedly connected to a bolt ring plate, and a fall-prevention connecting rope is bolted to the surface of the clamping frame, with one end of the fall-prevention connecting rope being bolted to the surface of the bolt ring plate.

[0010] Furthermore, a sliding plate is fixedly connected to the surface of the commutator plate near its side, and an annular groove is formed on the surface of the stabilizer seat, with the inner wall of the annular groove and the surface of the sliding plate being slidably connected.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0025] An adjustable robotic flexible polishing device includes a stable base 1. A driving robotic arm 2 is fixedly mounted on the top of the stable base 1. One end of the driving robotic arm 2 is rotatably connected to a clamping frame 3 via a driving end. A swing clamping plate 4 is rotatably connected to the inside of the clamping frame 3 via a driving end. A connecting rod 5 is magnetically attached to the surface of the swing clamping plate 4, and a locking screw 6 is connected between the surface of the connecting rod 5 and the surface of the swing clamping plate 4 via an internal thread groove. A stable seat 7 is fixedly connected to one end of the connecting rod 5. A servo motor 8 is fixedly mounted inside the stable seat 7. A reversing plate 9 is fixedly mounted to the output end of the servo motor 8. A connecting plate 10 is rotatably connected to the inside of the reversing plate 9 via a high-speed motor. A flexible polishing head 11 is clamped to the surface of the connecting plate 10, and the surface of the flexible polishing head 11 is connected to the surface of the connecting plate 10 via a connecting screw.

[0026] Specifically, such as Figures 1-5 As shown, a sliding plate 17 is fixedly connected to the surface of the commutator plate 9 near its side. An annular groove 18 is formed on the surface of the stabilizer 7, and the inner wall of the annular groove 18 is slidably connected to the surface of the sliding plate 17. An electric push rod 19 is fixedly installed on the surface of the sliding plate 17, and an electromagnetic suction plate 20 is fixedly installed at the output end of the electric push rod 19. The surface of the electromagnetic suction plate 20 and the inner wall of the annular groove 18 are magnetically attracted to each other. Under the action of the annular groove 18 and the sliding plate 17, the commutator plate 9 is kept stable and anti-tilting on the stabilizer 7. After the commutator plate 9 has completed its positioning, the electric push rod 19 can be operated to start and drive the electromagnetic suction plate 20 to move, so that the electromagnetic suction plate 20 can be magnetically attracted to the annular groove 18 for fixation.

[0027] Specifically, such as Figures 1-5 As shown, a dustproof mesh frame 21 is fixedly installed on the surface of the reversing plate 9 near its side. An air blower 22 is fixedly installed inside the dustproof mesh frame 21. The addition of the air blower 22 can blow away the debris during the flexible polishing operation of the flexible polishing head 11.

[0028] Please refer to Example 2 Figures 1-5 The difference between this embodiment and Embodiment 1 is that: an electric push rod 12 is fixedly installed inside the clamping frame 3, and a holding clamp 13 is fixedly connected to the output end of the electric push rod 12. The surface of the holding clamp 13 and the surface of the connecting rod 5 are magnetically engaged. An anti-slip pad 14 is fixedly connected to the surface of the holding clamp 13. The surface of the anti-slip pad 14 is coated with a wear-resistant coating. The electric push rod 12 controls the movement of the holding clamp 13 to constrain the upper part of the connecting rod 5. Under the action of the anti-slip pad 14, the fitting and constraint effect of the holding clamp 13 on the connecting rod 5 is enhanced.

[0029] Furthermore, a bolt ring plate 15 is fixedly connected to one end of the connecting pole 5, and a fall-prevention connecting rope 16 is bolted to the surface of the clamping frame 3. One end of the fall-prevention connecting rope 16 is bolted to the surface of the bolt ring plate 15. The fall-prevention connecting rope 16 on the surface of the clamping frame 3 can be externally connected to the bolt ring plate 15, which can prevent accidental falling during the replacement and maintenance of the connecting pole 5.

[0030] The working principle of this utility model is as follows: During use, a driving robotic arm 2 is installed on the top of the stable base 1 to drive and control the flexible polishing head 11 to change its position in a large direction. If the angle of the flexible polishing head 11 needs to be adjusted, the servo motor 8 can be controlled to drive the reversing plate 9 to rotate, completing the position reversing operation of the flexible polishing head 11. Common types of flexible polishing heads 11 can be replaced and installed above the connecting plate 10. Under the action of the annular groove 18 and the sliding plate 17, the reversing plate 9 is kept stable and anti-tilting on the stable base 7. After the reversing plate 9 completes its position positioning, the electric push rod 19 can be activated to move the electromagnetic suction plate 20, allowing the electromagnetic suction plate 20 to abut against the annular groove 18 for magnetic fixation, increasing the blowing effect. The air blower 22 blows away debris during the flexible polishing operation of the flexible polishing head 11, preventing debris accumulation on the workpiece. Inside the clamping frame 3, the connecting rod 5 can be clamped and constrained. The main body of the connecting rod 5 is constrained by the swing clamp 4 controlled by the drive, and the connection locking effect is strengthened by the locking screw 6. The upper clamping plate 13 is controlled by the electric push rod 12 to move and constrain the upper part of the connecting rod 5, which can form a multi-position anti-loosening positioning of the connecting rod 5 and facilitate subsequent disassembly and assembly of the connecting rod 5. The surface of the clamping frame 3 is provided with a fall-proof connecting rope 16 that can be connected to the external bolt ring plate 15 to prevent accidental falling during the replacement and maintenance of the connecting rod 5, ensuring the ease of adjustment, reversal and disassembly during the flexible polishing process.
