[0025] Please refer specifically to the attached Figures 1-3 A cutting device for a linear guide rail, comprising a U-shaped frame 1. A hydraulic rod 9 is installed at the inner top of the U-shaped frame 1. Then, a horizontal plate 11 is installed at the movable end of the hydraulic rod 9. A cutting knife 2 is installed on the upper surface of the horizontal plate 11, and a pressing plate 10 is installed on the side of the horizontal plate 11 away from the cutting knife 2.

[0026] Rectangular grooves are opened on both opposite sides of the U-shaped frame 1, and the guide rails are passed through the rectangular grooves. Connecting rods 12 are installed on both sides of the inner top of the rectangular grooves. A support plate 5 is installed on the side of the connecting rod 12 away from the U-shaped frame 1. A groove is opened on the side of the support plate 5 away from the U-shaped frame 1, and an adjusting plate 8 is inserted into the groove. A through groove communicating with the groove is opened on the upper surface of the support plate 5, and a screw rod 16 is inserted into the through groove. The screw rod 16 is connected to the adjusting plate 8. A nut 15 is threadedly connected to the end of the screw rod 16 away from the adjusting plate 8. The nut 15 is arranged on the upper surface of the support plate 5. The position of the adjusting plate 8 in the groove is adjusted by the cooperation of the screw rod 16 and the nut 15. Two conveying rollers 6 are arranged on the upper surface of the adjusting plate 8. The two conveying rollers 6 are respectively in contact with both sides of the inner top of the guide rail. Rotating grooves are opened at one opposite end of the two conveying rollers 6, and a T-shaped rod 7 is rotatably connected in the rotating groove. The end of the T-shaped rod 7 away from the conveying roller 6 is connected to the adjusting plate 8.

[0027] By opening a groove at the end of the support plate 5 away from the U-shaped frame 1 and installing an adjusting structure composed of an adjusting plate 8, a screw rod 16 and a nut 15 in the groove, the position of the conveying roller 6 is adjusted by the adjusting structure, so as to meet the transportation use of guide rails of different lengths.

[0028] A rectangular cylinder 3 with one end closed is installed on the upper surface of one of the support plates 5. An inclined plate 14 is inserted into the open end of the rectangular cylinder 3. The inclined plate 14 is in contact with a pressing plate 10. Slots are opened on both sides of the upper surface of the rectangular cylinder 3, and a T-shaped plate 4 is inserted into the slots. One end of the T-shaped plate 4 in the rectangular cylinder 3 is in contact with the inclined plate 14. The end of the T-shaped plate 4 away from the rectangular cylinder 3 is in contact with the inner top of the guide rail. A shock pad 17 is installed on the surface of the T-shaped plate 4 in contact with the guide rail, so as to reduce the vibration during the cutting of the guide rail. A rectangular pipe 13 is installed at the slot. The T-shaped plate 4 is inserted into the rectangular pipe 13.

[0029] By installing a support structure composed of a rectangular cylinder 3, an inclined plate 14 and a T-shaped plate 4 on the upper surface of the support plate 5, when the cutting tool 2 moves downward for cutting the guide rail, the pressing plate 10 is used to press against the support structure, so that the support structure supports the guide rail, separating the guide rail from the conveying roller 6, thus avoiding damage to the conveying roller 6 during cutting. At the same time, due to the upward support of the support structure and the downward movement of the cutting tool 2, the vibration during the cutting of the guide rail is reduced by two opposite acting forces.

[0030] And because the pressing plate 10 and the inclined plate 14 are perpendicularly arranged, and the inclined plate 14 and the T-shaped plate 4 are perpendicularly arranged, as long as the pressing plate 10 is in contact with the inclined plate 14, the T-shaped plate 4 will always support the guide rail, avoiding the separation of the T-shaped plate 4 from the guide rail caused by vibration during cutting.

[0031] The specific operation process of this utility model is as follows: Pass the guide rail through the rectangular groove, insert the support plate 5 into the guide rail, use the conveyor roller 6 to support the guide rail, reduce the friction force when the guide rail is pulled, and adjust the position of the adjusting plate 8 in the groove through the cooperation of the screw 16 and the nut 15, and then adjust the distance between the conveyor roller 6 and the U-shaped frame 1, so as to facilitate the support of guide rails of different lengths.

[0032] When the guide rail moves to the required length, control the movable end of the hydraulic rod 9 to extend, and then drive the cutter 2 to move towards the guide rail and cut the guide rail. When the cutter 2 moves downward, the pressing plate 10 also moves downward and contacts the inclined plate 14, pushing the inclined plate 14 to move into the rectangular cylinder 3. The inclined plate 14 moving into the rectangular cylinder 3 pushes the T-shaped plate 4 to move upward, and then replaces the conveyor roller 6 to support the guide rail, avoiding damage to the conveyor roller 6.

[0033] When the cutter 2 cuts the guide rail, a downward acting force is generated, and the T-shaped plate 4 generates an upward acting force under the action of the inclined plate 14. The guide rail is clamped by the up and down acting forces, reducing the probability of shaking during the cutting of the guide rail.

[0034] The above exemplary description of the present utility model is made in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as this non-substantial improvement is made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
