[0026] 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.

[0027] Example 1

[0028] Please see Figures 1-5 This is the first embodiment of the present invention, which provides an easy-to-operate floating grinding device, including...

[0029] The elastic frame 1 has a fixed frame 3 that can move back and forth on the inside. The elastic frame 1 provides a stable support foundation for the whole equipment. The fixed frame 3 on its inside can move back and forth on the left and right. This design allows the friction parts 4 and polishing parts 5 installed on the fixed frame 3 to follow the movement of the fixed frame 3 to perform grinding operations on the workpiece, increasing the grinding coverage and improving the flexibility of the equipment.

[0030] Friction component 4 is mounted on fixed frame 3. The friction component 4 is mounted on movable fixed frame 3 so that the friction component 4 can perform grinding action on the workpiece by reciprocating left and right with fixed frame 3. The fixed installation method ensures the stability of friction component 4 during grinding and avoids the grinding accuracy being affected by the shaking of friction component 4.

[0031] The polishing part 5 is detachably installed at the bottom of the friction component 4. The polishing part 5 is installed at the bottom of the friction component 4 in a detachable manner. When the polishing part 5 is worn out, it can be replaced easily and quickly without the need for large-scale disassembly of the entire equipment, which greatly shortens the replacement time and improves the maintenance efficiency of the equipment.

[0032] The stabilizing device includes a fastening seat 7 mounted on the bottom of the friction component 4, a fastening groove 71 formed at the bottom of the fastening seat 7, and an insert plate 51 disposed on the side surface of the polishing part 5, one end of which can be inserted into the fastening groove 71. When the insert plate 51 is inserted into the fastening groove 71, it can initially limit the relative position of the polishing part 5 and the friction component 4, preventing the polishing part 5 from shifting laterally during polishing, laying the foundation for subsequent stable connection, and enhancing the stability of the connection between the polishing part 5 and the friction component 4. A positioning post 72 is disposed at the bottom of the fastening seat 7, and a positioning hole 510 is formed inside the polishing part 5 for the positioning post 72 to pass through. The cooperation between the positioning post 72 and the positioning hole 510 plays a role in precise positioning during the installation of the polishing part 5. When the polishing part 5 is installed, the positioning pin 72 passes through the positioning hole 510, which can ensure that the polishing part 5 is accurately installed in the preset position at the bottom of the friction component 4, avoiding the impact of the polishing effect due to the installation position deviation, and improving the accuracy and efficiency of the installation. The threaded rod 8, which is opened in the corresponding through holes inside the insert plate 51 and the fastening seat 7, passes through the through holes and extends to the outside of the fastening seat 7. The threaded cylinder 9 is threadedly connected to one end of the threaded rod 8. After the threaded rod 8 passes through the corresponding through holes on the insert plate 51 and the fastening seat 7, it is threadedly connected to the threaded cylinder 9, which can firmly fix the insert plate 51 in the fastening groove 71, further strengthening the connection strength between the polishing part 5 and the friction component 4, preventing the two from separating due to vibration and other factors during the polishing process, and ensuring the stability of the polishing operation.

[0033] In this embodiment, preferably, it also includes ribs 710 symmetrically arranged at the opening of the fastening groove 71, and the ribs 710 can abut against the insert plate 51. The ribs 710 symmetrically arranged at the opening of the fastening groove 71 can abut against the insert plate 51, limit the insert plate 51 from the opening of the fastening groove 71, prevent the insert plate 51 from shaking in the fastening groove 71, enhance the stability of the connection between the insert plate 51 and the fastening seat 7, and further ensure the installation stability of the polishing part 5.

[0034] In this embodiment, preferably, it also includes guide rods 31 symmetrically arranged at the ends of the fixed frame 3, and guide holes 12 opened inside the elastic frame 1 for the guide rods 31 to pass through. The cooperation of the guide rods 31 and the guide holes 12 provides guidance for the left and right reciprocating movement of the fixed frame 3, ensuring that the fixed frame 3 will not deviate from the preset trajectory during the movement, thus ensuring the accuracy and stability of the grinding.

[0035] In this embodiment, preferably, a servo motor 11 is also installed on the top of the elastic frame 1, and the output shaft of the servo motor 11 passes through the elastic frame 1 and is connected to the rotating drum 6. The servo motor 11 provides power for the operation of the equipment, and its output shaft drives the rotating drum 6 to rotate. A protrusion 32 is provided on the fixed frame 3. The protrusion 32 provides a point of action for the rotating drum 6 to drive the fixed frame 3 to move. Through the cooperation between the rotating drum 6 and the protrusion 32, the rotational motion of the servo motor 11 is converted into the left and right reciprocating motion of the fixed frame 3, realizing the power transmission of the grinding action and ensuring the normal operation of the equipment.

[0036] In this embodiment, preferably, the outer wall of the rotating cylinder 6 is provided with a plurality of rotating rods 61, and the rotating rods 61 can abut against the protrusions 32 of the fixed frame 3. During the rotation of the rotating cylinder 6, the plurality of rotating rods 61 on the outer wall of the rotating cylinder 6 can abut against the protrusions 32 of the fixed frame 3 in sequence, thereby pushing the fixed frame 3 to move back and forth. The arrangement of the plurality of rotating rods 61 makes the movement of the fixed frame 3 more continuous and stable, ensuring the uniformity of the grinding operation.

[0037] In this embodiment, preferably, it also includes a movable plate 2 located above the elastic frame 1 and fixed with screws to the robotic arm. The movable plate 2 can be fixed with screws to the robotic arm, realizing convenient connection between the equipment and the robotic arm. This allows the equipment to expand the grinding range with the help of the movement of the robotic arm and adapt to different working scenarios. Symmetrically opened through holes are provided inside the movable plate 2, and symmetrically arranged sliding columns 13 are provided on the top of the elastic frame 1. The sliding columns 13 penetrate through the through holes of the movable plate 2, providing guidance for the up and down movement of the elastic frame 1 relative to the movable plate 2 and ensuring the accuracy of the movement. Springs 130, which are sleeved on the outer wall of the sliding columns 13 and connected to the elastic frame 1 and the movable plate 2 respectively, can play a buffering role when the equipment encounters unevenness on the surface of the workpiece or is subjected to impact during the grinding process. This reduces the damage of the impact force to the equipment and the workpiece, and at the same time allows the polishing part 5 to better fit the surface of the workpiece, ensuring the consistency of the grinding effect.

[0038] Example 2

[0039] Please see Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0040] An arc-shaped strip 120 is installed on the inner wall of the guide hole 12 near both ends, and a universal ball 1201 is provided on the arc-shaped strip 120 that can abut against the guide rod 31. The universal ball 1201 on the arc-shaped strip 120 on the inner wall of the guide hole 12 abuts against the guide rod 31, converting the sliding friction between the guide rod 31 and the guide hole 12 into rolling friction between the universal ball 1201 and the guide rod 31, reducing the friction between the two, making the left and right reciprocating movement of the fixed frame 3 smoother, reducing the wear of the equipment, and extending the service life of the equipment.

[0041] It should be noted that the specific structure and working principle of the robotic arm, servo motor 11, movable plate 2, sliding column 13, and spring 130 in this application have been disclosed in a floating grinding device with patent publication number CN217530371U.

[0042] The working principle and usage process of this utility model: The movable plate 2 is fixedly connected to the robot arm with screws to ensure a firm connection, so that the equipment can achieve multi-position and multi-angle grinding operations by means of the movement of the robot arm.

[0043] Align the positioning hole 510 on the polishing part 5 with the positioning post 72 on the bottom fastening seat 7 of the friction component 4, so that the positioning post 72 passes through the positioning hole 510, and achieve the initial positioning of the polishing part 5.

[0044] Push the polishing part 5 so that one end of the insert plate 51 on the side surface of the polishing part 5 is inserted into the fastening groove 71 at the bottom of the fastening seat 7. At this time, the ribs 710 symmetrically arranged at the opening of the fastening groove 71 press against the insert plate 51 to initially limit the position of the insert plate 51.

[0045] The threaded insert rod 8 is passed through the corresponding through holes inside the insert plate 51 and the fastening seat 7, and extends to the outside of the fastening seat 7. Then the threaded cylinder 9 is threaded to one end of the threaded insert rod 8, and the insert plate 51 is firmly fixed in the fastening groove 71, thus completing the stable connection between the polishing part 5 and the friction part 4.

[0046] Start the servo motor 11. The output shaft of the servo motor 11 drives the rotating drum 6 to rotate. Multiple rotating rods 61 on the outer wall of the rotating drum 6 abut against the protrusions 32 on the fixed frame 3 in sequence, pushing the fixed frame 3 to move back and forth left and right with the guide rod 31 and the guide hole 12 inside the elastic frame 1 as guides. Observe whether the movement of the fixed frame 3 is smooth and whether there is any jamming. At the same time, check whether the universal ball 1201 on the arc strip 120 on the inner wall of the guide hole 12 is properly abutting against the guide rod 31 to ensure good rolling friction effect.

[0047] The equipment is moved by the robotic arm, so that the polishing part 5 makes slight contact with the surface of the test workpiece. The spring 130 sleeved on the outer wall of the sliding column 13 can play a normal buffering role, ensuring that when the workpiece surface is uneven, the elastic frame 1 can move up and down normally relative to the movable plate 2, and the polishing part 5 can fit well against the workpiece surface.

[0048] Based on the material, shape, and grinding requirements of the workpiece to be ground, appropriate grinding speed, grinding force, and other parameters are set through the control system of the robotic arm.

[0049] The robotic arm moves the equipment, bringing the polishing part 5 into contact with the surface of the workpiece to be polished. The servo motor 11 is then restarted, and the fixed frame 3 drives the friction part 4 and the polishing part 5 to move back and forth to polish the workpiece. During the polishing process, the spring 130 adjusts the position of the elastic frame 1 in real time according to the surface condition of the workpiece to ensure good contact between the polishing part 5 and the surface of the workpiece. The rotating rod 61 continuously pushes the fixed frame 3 to move, ensuring the continuity and uniformity of the polishing operation.

[0050] When the polishing part 5 is worn and affects the polishing effect, first unscrew the threaded cylinder 9 from the threaded insert rod 8, pull out the threaded insert rod 8, then pull the polishing part 5 so that the insert plate 51 is pulled out from the fastening groove 71, the positioning pin 72 is disengaged from the positioning hole 510, and the old polishing part 5 is removed for replacement.

[0051] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
