[0037] The present invention will be further described below with reference to the accompanying drawings:

[0038] Example 1:

[0039] As attached Figure 1 To be continued Figure 6 and appendix Figure 9 To be continued Figure 14 As shown, in one embodiment of the present invention, an adjustable floating clamp trimming device includes a trimming frame 1. The trimming frame 1 contains three modules for trimming clamp positions: a long frame trimming module 3, an angle trimming module 5, and a wide frame trimming module 8. The long frame trimming module 3 includes a first drive motor 31, the output of which is connected to a first lead screw 32. A moving platform 4 is nested on the first lead screw 32. The angle trimming module 5 is located on the upper part of the moving platform 4. A wide frame trimming module 8 is installed on one side of the angle trimming module 5. The wide frame trimming module 8 includes a third drive motor 81. A long frame slide rail 11 is located in the middle of the interior of the trimming frame 1, and a controller 2 is installed on one side of the long frame slide rail 11. The moving platform 4 includes a long frame slide base 41. Angle adjustment rails 42 and fixed frames 43 are respectively installed on both sides; a synchronous rotating frame slide 6 is slidably connected in the angle adjustment rails 42, and an angle trimming module 5 is installed on one side of the angle adjustment rails 42. The angle trimming module 5 includes a second drive motor 51, and the output end of the second drive motor 51 is connected to a second lead screw 52. The second lead screw 52 is located in the angle adjustment rails 42 and passes through the synchronous rotating frame slide 6; a synchronous rotating shaft slide 7 is fixedly installed on one side of the fixed frame 43, and a third drive motor 81 is rotatably connected in the synchronous rotating shaft slide 7; the output end of the third drive motor 81 is connected to a third lead screw 82, and a telescopic frame 83 is nested in the third lead screw 82; a floating slide 9 is sleeved on the third lead screw 82, and floating column clamps 10 are densely distributed on the floating slide 9;

[0040] In this embodiment, during trimming, the long frame trimming module 3 moves the floating column clamp 10 along its length using a sliding moving platform 4. In use, the first drive motor 31 is activated, driving the first lead screw 32 to rotate. The lead screw 32 then drives the moving platform 4 to slide back and forth. Simultaneously, the long frame slide block 41 at the bottom of the moving platform 4 slides synchronously along the long frame slide rail 11, activating its supporting function. The wide frame trimming module 8 moves the floating column clamp 10 along its length using a sliding floating slide block 9. In use, the third drive motor 81 is activated. The three drive motors 81 drive the third lead screw 82 to rotate, and the third lead screw 82 drives the floating slide 9 to slide back and forth; the angle adjustment module 5 drives the wide frame adjustment module 8 to rotate a certain angle through the synchronous rotating frame slide 6, with an angle range of 0 to 30°. In use, the second drive motor 51 is started, and the second drive motor 51 drives the second lead screw 52 to rotate. The second lead screw 52 drives the synchronous rotating frame slide 6 to move back and forth, and the synchronous rotating frame slide 6 drives the wide frame adjustment module 8 connected to it to rotate a certain angle. Through the above adjustments, the four sets of fixtures are made to conform to the specifications of product 0.

[0041] Example 2:

[0042] As attached Figure 5 To be continued Figure 14 As shown in one embodiment of the present invention, an adjustable floating clamp trimming device includes a floating column clamp 10 comprising a floating column 101, a supporting connecting column 102, and a supporting locking column 103. The supporting connecting column 102 is nested inside the bottom of the floating column 101. The lower part of the supporting connecting column 102 is threadedly connected to the supporting locking column 103. The supporting locking column 103 is fixedly mounted on a floating slide 9. The floating column clamp 10 holds a product 0. The inner wall of the floating column 101 is densely covered with nail texture. 1011, the supporting connecting column 102 includes bolts 1021 and retaining rings 1022. A micro hydraulic pump 1023 is nested around the retaining ring 1022. A telescopic bracket 1024 is installed at the front end of the micro hydraulic pump 1023. A retaining plate 1025 is provided at the front end of the telescopic bracket 1024. A threaded groove 1031 is provided on the upper part of the supporting column 103. A return spring 104 is provided at the bottom of the floating column 101. The retaining ring 1022 and the floating column 101 are connected by the return spring 104.

[0043] In this embodiment, when using the fixture, after the product 0 is placed on the four sets of floating column fixtures 10, the floating column 101 is displaced downward under the action of the product 0's gravity. Then, the above fixture position adjustment steps are repeated to fine-tune the position of the floating column fixture 10. Finally, the micro hydraulic pump 1023 is started, and the micro hydraulic pump 1023 drives the telescopic bracket 1024 to unfold. The telescopic bracket 1024 pushes the plate 1025 to move out of the retaining ring 1022 and contact the dense nail texture 1011 on the inner wall of the floating column 101 to hold the floating column 101 in place.

[0044] Working principle

[0045] When using this invention, the positions of the three sets of trimming fixtures—long frame trimming module 3, angle trimming module 5, and wide frame trimming module 8—are determined according to the specifications of product 0.

[0046] During the trimming process, the long frame trimming module 3 moves the floating column clamp 10 in the length direction by sliding the front and rear moving platform 4. When in use, the first drive motor 31 is started, which drives the first lead screw 32 to rotate. The first lead screw 32 drives the moving platform 4 to slide back and forth. At the same time, the long frame slide block 41 at the bottom of the moving platform 4 slides synchronously along the long frame slide rail 11 to start the support function.

[0047] The wide frame trimming module 8 achieves the upward movement of the floating column clamp 10 through the forward and backward sliding floating slide 9. When in use, the third drive motor 81 is started, which drives the third lead screw 82 to rotate, and the third lead screw 82 drives the floating slide 9 to slide forward and backward.

[0048] The angle adjustment module 5 drives the wide frame adjustment module 8 to rotate a certain angle through the synchronous rotating frame slide 6. The angle range is 0 to 30°. When in use, the second drive motor 51 is started. The second drive motor 51 drives the second lead screw 52 to rotate. The second lead screw 52 drives the synchronous rotating frame slide 6 to move back and forth. The synchronous rotating frame slide 6 drives the wide frame adjustment module 8 connected to it to rotate a certain angle.

[0049] Through the above adjustments, the four sets of fixtures are made to conform to the specifications of product 0.

[0050] When using the fixture, after placing the product 0 on the four sets of floating column fixtures 10, the floating column 101 will move downward under the action of the product 0's gravity. Then, repeat the above fixture position adjustment steps to fine-tune the position of the floating column fixture 10. Finally, the micro hydraulic pump 1023 is started, and the micro hydraulic pump 1023 drives the telescopic bracket 1024 to unfold. The telescopic bracket 1024 pushes the plate 1025 to move out of the retaining ring 1022 and contact the dense nail texture 1011 on the inner wall of the floating column 101 to hold the floating column 101 in place.

[0051] During later maintenance, users can directly rotate and remove the damaged floating column clamp 10 from the support column 103 for replacement and maintenance.
