[0027] Please see Figure 1-5 A precision sheet metal cutting device includes a fixed platform 1 with a cutting opening 2. Two sliders 3 are slidably connected within the cutting opening 2. Slide plates 4 are fixedly connected to the top of each slider 3, and both slide plates 4 are located on the upper side of the fixed platform 1. Insertion rod assemblies 5 slide through each slide plate 4. Positioning strips 6 are fixedly connected to the adjacent ends of the two insertion rod assemblies 5, and the two positioning strips 6 are located between the two slide plates 4. Spring assemblies 7 are fitted onto the circumferential surfaces of each insertion rod assembly 5, and each spring assembly 7 is located between a slide plate 4 and a positioning strip 6. Slide tracks 8 are provided on each of the two positioning strips 6. Each slide rail 8 is slidably connected with a slide rod 9, and the lower part of each slide rod 9 passes through the cutout 2. The ends of the two slide rods 9 that are close to each other are fixedly connected with a pressure plate frame 10, and the two pressure plate frames 10 are slidably inserted into each other and located on the upper side of the cutout 2. The top of the fixed platform 1 is fixedly connected with a support frame 11, and the top wall of the support frame 11 is fixedly connected with a slide rail module 12. A laser cutting head 13 is provided on the slide rail module 12, and the laser cutting head 13 corresponds to the cutout 2. A positioning mechanism is provided on the fixed platform 1. The positioning mechanism is used to control the movement of the two slide plates 4 and the two slide rods 9 to achieve the positioning of the sheet metal parts.

[0028] In this embodiment, during the tight sheet metal cutting process, the sheet metal part is placed on the fixed table 1 between the lower sides of the two pressure plate frames 10 and the two positioning strips 6, so that the cutting position of the sheet metal part corresponds to the cutting opening 2. Then, the positioning mechanism controls the two sliders 3 to slide within the cutting opening 2. The two sliders 3 respectively drive the two slide plates 4 to move closer together. The two slide plates 4 respectively drive the two positioning strips 6 to move closer together through the two insertion rod groups 5 and the two spring groups 7. The two positioning strips 6 clamp and position the sheet metal part from both sides. As the two positioning strips 6 clamp, the two slide plates 4 continue to move, which will compress the two spring groups 7 on the two insertion rod groups 5 and shorten the distance between the two positioning strips 6 and the sheet metal part. As the two slide plates 4 approach the two positioning strips 6, the positioning mechanism pulls the two slide rods 9 to slide within the two slide rails 8. The two slide rods 9 pull the two pressure plate frames 10 down respectively. The two pressure plate frames 10 are pressed and fixed around the cutting position of the sheet metal part. After the sheet metal part is fixed, the slide rail module 12 controls the laser cutting head 13 to move. During the movement of the laser cutting head 13, the laser passes through the inner side of the two pressure plate frames 10 to cut the sheet metal part, so that the sheet metal part reaches the required size. Among them, when the two positioning strips 6 approach each other to clamp the sheet metal part, the two pressure plate frames 10 will insert into each other inward, which will not affect the movement of the two positioning strips 6.

[0029] Specifically, the positioning mechanism includes a base frame 141, a lifting cylinder 142, a connecting block 143, and two clamping linkage assemblies 144. The base frame 141 is fixedly connected to the bottom end of the fixed platform 1, the lifting cylinder 142 is fixedly connected to the bottom wall of the base frame 141, the connecting block 143 is fixedly connected to the output end of the lifting cylinder 142, and the two clamping linkage assemblies 144 are respectively hinged to the bottom ends of the two sliders 3 through hinge shafts, and one end of each of the two clamping linkage assemblies 144 is hinged to the connecting block 143 through hinge shafts.

[0030] In this embodiment, the base frame 141 is used to support the lifting cylinder 142. When cutting the sheet metal part, the lifting cylinder 142 controls the connecting block 143 to move down. The connecting block 143 causes the two sliders 3 to move in the cutting opening 2 towards each other through two clamping linkage groups 144, so that the positioning strip 6 clamps and positions the sheet metal part on both sides.

[0031] Specifically, the positioning mechanism also includes two clamping links 145. The two clamping links 145 are respectively hinged to the bottom ends of the two sliders 3 via hinge shafts. One end of the two clamping links 145 is respectively hinged to the bottom ends of the two slide rods 9 via hinge shafts. The two clamping links 145 are respectively located inside the two clamping link assemblies 144.

[0032] In this embodiment, after the two positioning strips 6 come into contact with the two sides of the sheet metal part, the connecting block 143 continues to move down, causing the two sliders 3 to continue to move. The two sliders 3 drive the two sliding plates 4 to gradually approach the two positioning strips 6. At the same time, the two sliders 3 pull the two sliding rods 9 through the two pressing connecting rods 145 to slide in the two sliding tracks 8 respectively. The two sliding rods 9 pull the two pressure plate frames 10 down to press and fix the sheet metal part.

[0033] Specifically, a fixed rod assembly 15 is fixedly connected to the bottom end of the fixed platform 1, and a connecting block 143 is slidably connected to the fixed rod assembly 15.

[0034] In this embodiment, the fixed rod group 15 is used to assist the movement of the connecting block 143, so that the lifting and lowering of the connecting block 143 remains stable.

[0035] Specifically, anti-slip strips 16 are fixedly connected to the bottom ends of both pressure plate frames 10.

[0036] In this embodiment, the anti-slip strip 16 is used to increase the friction at the bottom of the two pressure plate frames 10, which can better press and fix the sheet metal parts.

[0037] Specifically, a feeding port 17 is fixedly connected to one side of the fixed platform 1, and the feeding port 17 is located on one side of the cutting port 2.

[0038] In this embodiment, the discharge port 17 is used for the discharge of sheet metal parts after cutting, so that the sheet metal products can be accurately slid to the next processing step.

[0039] Working principle: During tight sheet metal cutting, the sheet metal part is placed on the fixed table 1 between the lower sides of the two pressure plate frames 10 and the two positioning strips 6, so that the cutting position of the sheet metal part corresponds to the cutting opening 2. Then, the connecting block 143 is lowered by the lifting cylinder 142. The connecting block 143 causes the two sliders 3 to slide in the cutting opening 2 through the two clamping linkage groups 144. The two sliders 3 drive the two sliding plates 4 to move closer together. The two sliding plates 4 drive the two positioning strips 6 to move closer together through the two insertion rod groups 5 and the two spring groups 7. The two positioning strips 6 clamp and position the sheet metal part from both sides. As the two positioning strips 6 clamp, the two... As the slide plate 4 continues to move, it compresses the two spring groups 7 on the two plug rod groups 5 and shortens the distance between them and the two positioning bars 6. As the two slide plates 4 approach the two positioning bars 6, the two sliders 3 pull the two sliding rods 9 through the two clamping connecting rods 145 to slide in the two slide rails 8 respectively. The two sliding rods 9 drive the two pressure plate frames 10 to press down. The two pressure plate frames 10 are pressed and fixed around the cutting position of the sheet metal part. After the sheet metal part is fixed, the slide rail module 12 controls the laser cutting head 13 to move. During the movement of the laser cutting head 13, the laser passes through the inside of the two pressure plate frames 10 to cut the sheet metal part, so that the sheet metal part reaches the required size.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
