Their main purpose is to ensure the stability and safety of workpieces during the processing process, as well as to maintain the accurate position and posture of workpieces.

[0003] Flexible stretching usually refers to the characteristics that a certain material or device can show softness, elasticity and adaptability during the stretching process. The flexible stretching clamping assembly usually has a certain elasticity or deformability, can adapt to objects of different shapes and sizes, and can provide appropriate clamping force during the stretching process.

[0004] For some materials that are easy to deform and have a soft texture, such as cloth, traditional clamping devices cannot effectively fix and stretch them, and the clamping devices are prone to damage the cloth during the clamping process, resulting in waste of materials. Therefore, a flexible stretching clamping assembly is proposed to solve the above problems. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 2, An embodiment provided by the present utility model: a flexible stretching clamping assembly, including a workbench 1. Square grooves 6 are provided on the side walls of the workbench 1. Two slide rails 12 are fixedly connected to the inner wall of the top of the workbench 1. Clamping bases 4 are slidably connected to both ends of the bottom of the slide rails 12. A first rotating rod 11 is rotatably connected to the bottom of the clamping base 4. One end of the first rotating rod 11 away from the clamping base 4 is rotatably connected to a sliding piece 9. Four upright columns 10 are fixedly connected to the top of the sliding piece 9. A baffle 8 is fixedly connected between two adjacent upright columns 10. A handle 2 is fixedly connected to the outside of the baffle 8. A first spring 7 is sleeved on the outside of the handle 2. A clamping plate 3 is arranged on the top of the clamping base 4. A torsion spring 13 is fixedly connected between the inside of the clamping plate 3 and the inside of the clamping base 4. A rubber head 5 is inserted into one end of the clamping plate 3 away from the torsion spring 13. A fixing component is arranged on the top of the rubber head 5, and the fixing component is used for fixing between the rubber head 5 and the clamping plate 3. The clamping base 4 is arranged inside the square groove 6. The top of the sliding piece 9 is slidably connected to the inner wall of the top of the workbench 1. The outside of the handle 2 is slidably connected to the inside of the workbench 1. One end of the first spring 7 is fixedly connected to the outside of the baffle 8, and the other end of the first spring 7 is fixedly connected to the inner wall of the workbench 1. The rubber head 5 abuts against the top end of the workbench 1, and the bottom of the rubber head 5 is serrated.

[0032] Specifically, when using the device, first press the clamping plate 3 on the top of the workbench 1, then lay the flexible material flat on the top end of the workbench 1, release the clamping plate 3 under the action of the torsion spring 13, and the rubber head 5 fixed on the outside of the clamping plate 3 firmly clamps the flexible material. At this time, pull the handle 2 outwards. Since the upright columns 10 are fixedly connected to both sides of the baffle 8, the baffle 8 slides towards the outside of the workbench 1 along with the handle 2. At this time, the first spring 7 is compressed and the sliding piece 9 is also driven to slide. Then the first rotating rod 11 rotates and pushes the clamping base 4 outwards. The top of the clamping base 4 slides at the bottom of the slide rail 12. The clamping base 4 is located inside the square groove 6. At this time, the flexible material on the top of the workbench 1 is also stretched and smoothed.

[0033] Referring to Figure 3 - Figure 4 , The fixing component includes a clamping box 14. The bottom of the clamping box 14 is fixedly connected to the top of the rubber head 5. A button 15 is slidably connected to the inside of the clamping box 14. A limiting rod 17 is slidably connected to the inside of the button 15. A second spring 16 is sleeved on the outside of the limiting rod 17. A second rotating rod 18 is rotatably connected to the left end of the button 15. One end of the second rotating rod 18 away from the button 15 is rotatably connected to a bolt 19. A limiting block 20 is fixedly connected to the front side of the bolt 19. Another limiting rod 17 is slidably connected to the inside of the limiting block 20. The top of the second spring 16 is fixedly connected to the bottom of the button 15, and the bottom of the second spring 16 is fixedly connected to the inner wall of the clamping box 14. The outside of the bolt 19 is slidably connected to the inside of the clamping box 14, and the second rotating rod 18 can be telescopic.

[0034] Specifically, after long-term use of the device, it is necessary to replace the rubber head 5 on the outer side of the clamping plate 3. At this time, press the button 15. The button 15 slides on the outer side of the limiting rod 17 and compresses the second spring 16. The second rotating rod 18 on the outer side of the button 15 rotates. Since the center of the second rotating rod 18 is fixed with a shaft and the second rotating rod 18 itself can be telescoped, at this time, the other side of the second rotating rod 18 rotates and pulls the bolt 19 into the inside of the card box 14. A limiting block 20 is fixed on the outer side of the bolt 19, and the limiting block 20 also slides on the outer side of another limiting rod 17. At this time, the bolt 19 is pulled out. Then, replace the new rubber head 5 and fix the card box 14 on the top of the rubber head 5. After releasing the button 15, the bolt 19 penetrates through the outer wall of the rubber head 5 and inserts into the inside of the clamping plate 3 to complete the fixation of the rubber head 5.

[0035] Working principle: The flexible material can be initially fixed by the clamping plate 3 and the clamping base 4. Specifically, first press the clamping plate 3, and then place the flexible material under the clamping plate 3. A torsion spring 13 is fixed inside the clamping plate 3 and the clamping base 4. Under the action of the torsion spring 13, release the clamping plate 3, and the clamping plate 3 will tightly clamp the flexible material. At this time, pull the handle 2, and the baffle 8 drives the sliding piece 9 to slide out of the workbench 1. The first rotating rod 11 rotatably connected to the bottom of the sliding piece 9 also rotates accordingly, and pushes the clamping base 4 sliding at the bottom of the slide rail 12 outward. Multiple clamping bases 4 slide outward and stretch the clamped object; after multiple uses, it is necessary to replace the rubber head 5. Just press the button 15, and the second rotating rod 18 will rotate as the button 15 slides down and pull out the bolt 19 from the inside of the clamping plate 3. At this time, a new rubber head 5 can be replaced. Continue to fix the card box 14 on the top of the rubber head 5 and release the button 15. Under the action of the second spring 16, finally, the bolt 19 will penetrate through the rubber head 5 along the preset hole and finally insert into the inside of the clamping plate 3 to complete the replacement and fixation of the rubber head 5.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
