[0001] The utility model relates to the technical field of clamping or positioning devices for workpieces, and particularly relates to a precise positioning and adjusting device for punching fabrics. Background Technique

[0002] In the fabric cutting production process of garment manufacturing enterprises, fabrics need to go through processes such as marking, punching, cutting, sewing, buttoning, quality inspection, and boxing according to the garment patterns designed by designers before being made into finished garments and put on the market. When punching fabrics, a fabric punching machine is used. The fabric punching machine fixes the fabric through a fixed fixture and then sends it into the interior of the punching machine for punching work.

Detailed implementation manners

[0035] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 4 , the present invention provides a new technical solution: a precise positioning and adjusting device for punching fabrics, including a housing 1. A computer 2 and a punching device 3 are fixedly connected to the front side of the housing 1. The computer 2 and the punching device 3 are arranged left and right. The punching device 3 can perform punching work on the fabric. An inlet 4 is integrally formed on the front side of the housing 1. The inlet 4 is communicated with the inside of the housing 1. A fixing clamp is arranged inside the inlet 4. The fixing clamp can clamp the fabric and feed it into the inside of the housing 1 for punching. At the same time, the fixing clamp also has the ability to adjust. The fixing clamp includes an upper clamping surface 5, a lower clamping surface 6, a rotating shaft 7, two buckles 8, a first threaded rod 9, a first motor assembly 11, three first connecting rods 14, a second threaded rod 15, a second motor assembly 17 and three second connecting rods 20.

[0037] Furthermore, the shapes of the upper clamping surface 5 and the lower clamping surface 6 are both rectangular frames formed by splicing four L-shaped blocks. The upper clamping surface 5 and the lower clamping surface 6 are arranged up and down. The rotating shaft 7 is rotatably connected between the upper clamping surface 5 and the lower clamping surface 6. The rotating shaft 7 is composed of two left and right sections. The upper clamping surface 5 and the lower clamping surface 6 are rotatably connected through the rotating shaft 7. Two buckles 8 are both fixedly connected to the rear sides of the upper clamping surface 5 and the lower clamping surface 6. The two buckles 8 are arranged left and right. The upper clamping surface 5 and the lower clamping surface 6 are clamped together through the buckles 8. The first threaded rod 9 is threadedly connected inside the upper clamping surface 5. The first threaded rod 9 is composed of two threaded rods with opposite thread directions. The two sections of the first threaded rod 9 respectively thread through the inside of the left and right two L-shaped blocks. A first installation groove 10 is opened inside the upper clamping surface 5. The first installation groove 10 is arranged on the right side of the first threaded rod 9. The first motor assembly 11 is fixedly connected inside the first installation groove 10. The output end of the first motor assembly 11 is fixedly connected with a first transmission shaft 12. The left end of the first transmission shaft 12 is fixedly connected with the right end of the first threaded rod 9. First connection grooves 13 are opened inside both the upper clamping surface 5 and the lower clamping surface 6. The first connection grooves 13 are respectively opened inside the left and right two L-shaped blocks. The position of the first threaded rod 9 is not provided with the first connection groove 13. Therefore, three first connection grooves 13 are opened. Three first connecting rods 14 are respectively slidably connected inside the three first connection grooves 13.

[0038] Further, the second threaded rod 15 is threadedly connected inside the lower clamping surface 6. The second threaded rod 15 is also composed of two threaded rods with opposite thread directions. The two sections of the second threaded rod 15 respectively thread through the interiors of the front and rear L-shaped blocks. A second installation groove 16 is formed inside the lower clamping surface 6. The second installation groove 16 is arranged at the rear side of the second threaded rod 15. The second motor assembly 17 is fixedly connected inside the second installation groove 16. The output end of the second motor assembly 17 is fixedly connected with a second transmission shaft 18. The front end of the second transmission shaft 18 is fixedly connected with the rear end of the second threaded rod 15. Second connection grooves 19 are formed inside both the upper clamping surface 5 and the lower clamping surface 6. The second connection grooves 19 are respectively formed inside the front and rear L-shaped blocks. The position of the second threaded rod 15 is not provided with a second connection groove 19. Thus, there are also three second connection grooves 19. Three second connecting rods 20 are respectively slidably connected inside the three second connection grooves 19.

[0039] Further, when starting to work, first rotate the upper clamping surface 5 to open the fixing fixture, then place the fabric on the upper side of the lower clamping surface 6, and then close the upper clamping surface 5. At this time, the upper clamping surface 5 and the lower clamping surface 6 will clamp the fabric. Then, the upper clamping surface 5 and the lower clamping surface 6 are clamped together through the buckle 8. Then, the fixing fixture is sent into the interior of the housing 1 from the inlet 4, and the fabric is punched by the punching device 3. When the fabric material is relatively soft, after completing the clamping and fixing, start the first motor assembly 11. The first motor assembly 11 starts to transmit power from the output end, drives the first transmission shaft 12 to rotate. The first transmission shaft 12 drives the first threaded rod 9 to rotate. The first threaded rod 9 drives the left and right L-shaped blocks of the upper clamping surface 5 to move. Because the two sections of the first threaded rod 9 have opposite thread directions, the left and right L-shaped blocks start to move towards the mutually separated sides. The front two L-shaped blocks drive the rear two L-shaped blocks to move through the second connecting rod 20. At the same time, the upper clamping surface 5 will drive the lower clamping surface 6 to move synchronously through the rotating shaft 7 and the buckle 8. Thus, the left and right directions of the fabric will be stretched.

[0040] Further, at the same time, start the second motor assembly 17. The second motor assembly 17 starts to transmit power from the output end, drives the second transmission shaft 18 to rotate. The second transmission shaft 18 drives the second threaded rod 15 to rotate. The second threaded rod 15 drives the front and rear L-shaped blocks of the lower clamping surface 6 to move. Because the two ends of the second threaded rod 15 also have opposite thread directions, the front and rear L-shaped blocks start to move towards the mutually separated sides. The left two L-shaped blocks drive the right two L-shaped blocks to move through the first connecting rod 14. At the same time, the lower clamping surface 6 will also drive the upper clamping surface 5 to move synchronously through the rotating shaft 7 and the buckle 8. Thus, the front and rear directions of the fabric will also be stretched. In this way, adjustment can still be carried out after the fixing fixture is clamped. Thus, the soft fabric will not be deformed and wrinkled when being punched, thus improving the positioning effect and further improving the punching accuracy.

[0041] Working principle: When starting to work, first rotate the upper clamping surface 5 to open the fixing fixture. Then place the fabric on the upper side of the lower clamping surface 6, and then close the upper clamping surface 5. At this time, the upper clamping surface 5 and the lower clamping surface 6 will clamp the fabric. Then, connect the upper clamping surface 5 and the lower clamping surface 6 through the buckle 8. After that, send the fixing fixture into the interior of the housing 1 from the inlet 4, and punch the fabric through the punching device 3. When the fabric material is relatively soft, after completing the clamping and fixing, start the first motor assembly 11. The first motor assembly 11 transmits power from the output end, drives the first transmission shaft 12 to rotate, the first transmission shaft 12 drives the first threaded rod 9 to rotate, and the first threaded rod 9 drives the left and right L-shaped blocks of the upper clamping surface 5 to move. Because the thread directions of the two sections of the first threaded rod 9 are opposite, the left and right L-shaped blocks start to move away from each other. The front two L-shaped blocks drive the rear two L-shaped blocks to move through the second connecting rod 20. At the same time, the upper clamping surface 5 will drive the lower clamping surface 6 to move synchronously through the rotating shaft 7 and the buckle 8, so that the left and right directions of the fabric will be stretched.

[0042] Furthermore, at the same time, start the second motor assembly 17. The second motor assembly 17 transmits power from the output end, drives the second transmission shaft 18 to rotate, the second transmission shaft 18 drives the second threaded rod 15 to rotate, and the second threaded rod 15 drives the front and rear L-shaped blocks of the lower clamping surface 6 to move. Because the thread directions of the two ends of the second threaded rod 15 are also opposite, the front and rear L-shaped blocks start to move away from each other. The left two L-shaped blocks drive the right two L-shaped blocks to move through the first connecting rod 14. At the same time, the lower clamping surface 6 will also drive the upper clamping surface 5 to move synchronously through the rotating shaft 7 and the buckle 8, so that the front and rear directions of the fabric will also be stretched.
