[0002] In the process of mechanical manufacturing, when assembling or aligning the pin holes of various mechanical parts, there are often positioning deviations due to positioning accuracy issues. Positioning deviations can cause direct rigid collisions between the connecting ends during assembly, leading to assembly failure or even damage to the parts. Floating modules can buffer rigid collisions during the assembly process.

[0036] Furthermore, the sleeve 8 includes a connecting part 10 and a sleeve part 11, the sleeve part 11 is fixedly connected to the connecting part 10, and a limiting hole 12 is provided on the top plate of the sleeve part 11;

[0042] Furthermore, the fixed base 1 is arranged parallel to the floating plate 2.

[0043] The working principle of the above technical solution:

[0044] A self-resetting omnidirectional floating module includes a fixed base 1 and a floating plate 2. A through hole 3 is opened at the center of the bottom surface of the fixed base 1. A limiting post 4 is fixedly installed at the center of the bottom surface of the floating plate 2. The lower end of the limiting post 4 extends to the lower part of the through hole 3 and a sliding plate 5 is provided. The diameter of the through hole 3 is larger than the diameter of the limiting post 4 and smaller than the diameter of the sliding plate 5. At least three self-resetting units are arranged around the through hole 3 between the fixed base 1 and the floating plate 2.

[0045] The self-resetting unit includes a return block 6 disposed on the bottom surface of the floating plate 2. A conical groove 7 is formed on the bottom surface of the return block 6, and the top of the conical groove 7 is arc-shaped.

[0046] The return block 6 includes a positioning post 61 and a body part 62. The positioning post 61 is fixedly installed on the upper end face of the body part 62, and the conical groove 7 is opened on the lower end face of the body part 62. The positioning post 61 is connected to the positioning hole 21. The shape of the positioning post 61 and the positioning hole 21 are adapted to each other. The positioning post 61 is fixedly connected in the positioning hole 21. A countersunk screw hole can be opened on the top surface of the floating plate 2 at a position corresponding to the positioning hole 21. A threaded hole can be opened on the upper end face of the positioning post 61. The positioning post 61 is fixed in the positioning hole 21 by countersunk screws.

[0047] A sleeve 8 is fixedly installed on the top surface of the fixed base 1 at a position corresponding to the floating plate 2. A telescopic column 9 is slidably installed inside the sleeve 8. The shape of the top end of the telescopic column 9 is adapted to the shape of the top end of the conical groove 7, and the top end of the telescopic column 9 contacts the inner wall of the conical groove 7.

[0048] The top of the telescopic column 9 can be set as a hemisphere, and the radius of the hemisphere is less than or equal to the radius of the arc at the top of the conical groove 7.

[0049] The fixed base 1 can be directly installed on the end flange of the robotic arm or other mechanisms, while the actuator is installed on the floating end. The actuator is used for the assembly of mechanical parts.

[0050] A bushing 16 is provided on the through hole 3. The inner diameter of the bushing 16 is larger than the diameter of the limiting post 4. Under the action of the spring force of the spring 15, the telescopic post 9 pushes the return block 6 upward. The top of the telescopic post 9 is opposite to the top of the conical groove 7. At least three telescopic posts 9 arranged in an array push the floating plate 2 upward horizontally.

[0051] The diameter of the sliding plate 5 at the lower end of the limiting post 4 fixedly connected to the center of the floating plate 2 is larger than the inner diameter of the bushing 16, so that the sliding plate 5 cannot be dislodged upward from the bushing 16. Since the inner diameter of the bushing 16 is larger than the diameter of the limiting post 4, when the actuator installed on the floating plate 2 is assembling parts, if the parts are impacted due to positioning deviation, the impact force is transmitted to the floating plate 2, the telescopic post 9 compresses the spring 15, the telescopic post 9 moves downward, and the floating plate 2 can move in all directions. Since the inner diameter of the bushing 16 is larger than the diameter of the limiting post 4, the limiting shaft 4 can move in all directions within the bushing 16. However, due to the restriction of the sliding plate 5, the limiting post 4 cannot be dislodged from the fixed seat 1, thereby realizing the omnidirectional floating of the floating plate 2 without separating from the fixed seat 1.

[0052] A limiting hole 12 is provided on the top plate of the sleeve part 11. The limiting hole 12 can restrict the limiting part 14 to move only inside the sleeve part 11, so that the telescopic column 9 cannot be dislodged from the sleeve part 11.

[0053] The conical surface of the conical groove 7 presses against the top of the telescopic column 9, causing the axes of the conical groove 7 and the telescopic column 9 to shift. Depending on the direction of the force or torque applied to the floating plate 2, the floating plate 2 can move and rotate in various directions.

[0054] After assembly, the floating plate 2 is no longer subject to external forces. The upward elastic force of the spring 15 pushes the telescopic column 9 upward. The top of the telescopic column 9 presses against the conical surface of the conical groove 7, causing the return block 6 to move back to the position where the axis of the conical groove 7 coincides with the axis of the telescopic column 9. The floating plate 2 then automatically resets.

[0055] The floating plate 2, the limiting post 4, and the sliding plate 5 can be coaxially arranged. A threaded hole is opened on the lower end face of the limiting post 4, and an installation hole is opened in the center of the sliding plate 5. The sliding plate 5 is installed to the lower end of the limiting post 4 using screws 19.

[0056] The telescopic column 9 can be connected to the fixed base 1 via the connecting part 10, such as... Figure 5 As shown, the connecting part 10 can be set as a rectangle. Mounting holes are opened on both sides of the connecting part 10 located in the sleeve part 11. The connecting part 10 is fixed to the fixing seat 1 with screws. During installation, the telescopic column 9 can be inserted into the sleeve part 11 first, and then the spring 15 can be inserted. Then the connecting part 10 and the sleeve part 11 can be fixedly connected. Welding or threaded connection can be selected to connect the connecting part 10 and the sleeve part 11.

[0057] The upward force of the spring 15 causes the floating plate 2 to be subjected to an upward force. The floating plate 2 is limited by the bushing 16 through the sliding plate 5 at the lower end of the limiting post 4 and cannot be separated from the fixed seat 1. There is a certain pressure between the sliding plate 5 and the lower bushing 16. When the limiting post 4 moves in the bushing 16, there is friction between the upper end surface of the sliding plate 5 and the lower end surface of the bushing 16, which will affect the floating effect. A self-lubricating coating is fixedly provided on the upper surface of the sliding plate 5 to reduce the friction between the sliding plate 5 and the bushing 16 and make the floating effect better. The self-lubricating coating can be made of polytetrafluoroethylene or polyimide.

[0058] The beneficial effects of the above technical solution are as follows:

[0059] The self-resetting omnidirectional floating module of this utility model has a self-resetting unit set between the fixed base and the floating plate. After the floating plate is deflected by force, it will automatically reset to the initial position under the action of the self-resetting unit when there is no external force. It does not require additional power, has a simple structure, low cost, and high flexibility of use.
