A size adjustment mechanism 5 is installed on the guide frame 4, and the size adjustment mechanism 5 includes an adjustment component 51 and an assembly guide frame 52. The adjustment component 51 is installed on the guide frame 4, and the assembly guide frame 52 is slidably arranged on the adjustment component 51. A clamping mechanism 6 is installed on the assembly guide frame 52, and the clamping mechanism 6 is used to clamp and fix the alloy rod and extend the alloy rod along the second direction. A size precision component 53 is provided on the side of the guide frame 4 close to the scale 54, and the size precision component 53 is used to accurately determine the cutting length of the alloy rod.

[0024] Please refer to Figure 2 and Figure 3 The guide frame 4 is provided with two preset grooves 511 extending in the second direction. The adjustment assembly 51 includes a transmission screw 512 and a guide rod 518. The transmission screw 512 and the guide rod 518 are respectively installed in the two preset grooves 511. One end of the transmission screw 512 is fixed with a first bevel gear 513. One side of the first bevel gear 513 is meshed with a second bevel gear 514. The middle part of the second bevel gear 514 is fixed with a transmission rod 515. The end of the transmission rod 515 passes through the side wall of the guide frame 4 and is fixed with a hand-held Block 516, an assembly through hole is provided on the assembly guide frame 52 at a position corresponding to the guide rod 518, and the guide rod 518 passes through the assembly through hole, and an assembly threaded hole 517 is provided on the assembly guide frame 52 at a position corresponding to the transmission screw 512, and the transmission screw 512 and the assembly threaded hole 517 cooperate with each other, so that the transmission screw 512 can drive the assembly guide frame 52 to move along the second direction, thereby adjusting the cutting length of the alloy rod, and the adjustment operation is performed after the alloy rod is clamped and fixed, and no dimensional deviation will occur, thereby ensuring the shearing accuracy.

[0025] A preset slide groove 531 extending along the second direction is provided on the side of the guide frame 4 close to the scale 54. The size precision component 53 includes an L-shaped slide plate 532 and a laser 534. The L-shaped slide plate 532 includes a horizontal part and a vertical part. The horizontal part of the L-shaped slide plate 532 can be movably arranged in the preset slide groove 531 along the second direction. The upper surface of the vertical part of the L-shaped slide plate 532 is located above the upper surface of the assembly guide frame 52 to ensure that when the clamping mechanism 6 clamps the alloy rod, the alloy rod can be made to contact the vertical part of the L-shaped slide plate 532 by moving the assembly guide frame 52. A laser 534 is installed on the lower surface of the horizontal part of the L-shaped slide plate 532 at a position corresponding to the side of the vertical part of the L-shaped slide plate 532 close to the guide frame 4, so as to accurately determine the cutting length of the alloy rod, thereby ensuring the accuracy of alloy rod cutting.

[0026] Preferably, the minimum distance from the cutting machine 8 to the upper surface of the processing table 1 is greater than the distance from the upper surface of the horizontal part of the L-shaped slide 532 to the upper surface of the processing table 1, so as to prevent the horizontal part of the L-shaped slide 532 from interfering with the cutting of the cutting machine 8 and ensure the cutting effect of the alloy rod.

[0027] Preferably, the dimension precision component 53 also includes a universal support wheel frame 533. A universal support wheel frame 533 is provided on the lower surface of the horizontal part of the L-shaped slide 532 at one end away from the guide frame 4. The universal support wheel frame 533 is in contact with the upper surface of the processing table 1 so that the horizontal part of the L-shaped slide 532 always moves along the second direction, thereby ensuring that the laser emitted by the laser 534 is always perpendicular to the scale 54 to avoid dimensional deviation.

[0028] After the alloy bar is clamped, the operator can rotate the hand-held block 516 to make the transmission rod 515 rotate with the second bevel gear 514, and the first bevel gear 513 meshed with the gear can rotate with the transmission screw 512, and the transmission screw 512 can carry the assembly guide frame 52 and the clamped bar to cooperate with the guide rod 518 to perform horizontal displacement. During the displacement of the bar, one end of it will contact the vertical part of the L-shaped slide plate 532, and during the continuous displacement, it will carry the L-shaped slide plate 532 to guide and displace on one side of the guide frame 4. At this moment, it is at the lower end of the L-shaped slide plate 532. The laser 534 will move on the scale 54 set on the processing table 1. Since the vertical position of the emitting end of the laser 534 corresponds to the side of the vertical part of the L-shaped slide 532 close to the guide frame 4, the corresponding scale 54 pointed by the laser 534 is the distance of the exposed rod, which makes it easy for personnel to determine the point of the rod to be sheared. After the determination is completed, the guide frame 4 moves along the guide protrusion 3. During this process, the cutting machine 8 is turned on. When the rod contacts the shearing piece of the cutting machine 8, the cutting operation of its corresponding point can be achieved. It is portable and practical.

[0029] In order to facilitate the removal of the cut rods and prevent the cut rods from piling up on the surface of the processing table 1 and affecting the cutting effect of the cutting machine 8, while improving safety and preventing personal injury, both sides of the horizontal part of the L-shaped slide 532 are provided with accommodating protrusions (not shown in the figure), and both sides of the preset slide 531 are provided with accommodating slides that cooperate with the accommodating protrusions. The horizontal part of the L-shaped slide 532, the accommodating protrusions on both sides of the horizontal part of the L-shaped slide 532, the vertical part of the L-shaped slide 532 and the side of the guide frame 4 close to the scale 54 together form an accommodating space, so that the cut rods fall into the accommodating space and move away from the cutting machine 8 along the guide protrusion 3 with the guide frame 4, so that the cut rods can be safely removed.

[0030] Furthermore, the minimum distance from the cutting machine 8 to the upper surface of the processing table 1 is greater than the distance from the upper surface of the accommodating protrusion to the upper surface of the processing table 1 to prevent the accommodating protrusion from interfering with the cutting of the cutting machine 8 and ensure the cutting effect of the alloy rod.

[0031] Please refer to Figure 2 and Figure 4 The clamping mechanism 6 includes a fixed limiting plate 61, a fixed frame 62 and a movable limiting plate 66. The fixed limiting plate 61 is fixedly arranged on one side of the upper surface of the assembly guide frame 52. The other side of the upper surface of the assembly guide frame 52 is fixedly provided with a fixed frame 62. A screw groove 63 is provided in the middle of the fixed frame 62. A push screw 64 is screwed in the middle of the screw groove 63. A movable shaft 65 is connected to the end of the push screw 64. The other end of the movable shaft 65 is connected to a movable limiting plate 66. The movable limiting plate 66 is connected to the push screw 64 by the movable shaft 65. A movable groove 68 extending along the first direction is provided on the upper surface of the assembly guide frame 52. The movable limiting plate 66 is movably arranged in the movable groove 68. The fixed limiting plate 61, the fixed frame 62 and the movable limiting plate 66 all extend in the second reverse direction, so that the clamped alloy bar extends along the second direction to facilitate cutting operations.

[0032] The staff can place the alloy rod on the inner side of the fixed limit plate 61 and the movable limit plate 66 above the assembly guide frame 52 in advance, and then manually advance the screw 64. Under the guidance of the threaded groove 63 in the middle of the fixed frame 62 and the movable cooperation of the movable shaft 65 at the end of the screw, the movable limit plate 66 can cooperate with the fixed limit plate 61 under the guidance of the movable groove 68 to clamp and limit the rod.

[0033] Preferably, protective pads 67 are fixedly provided on the inner side surfaces of the fixed limiting plate 61 and the movable limiting plate 66 that are close to each other, so as to further improve the anti-slip property and ensure the clamping effect on the alloy rod.

[0034] In a preferred embodiment, see Figure 1 and Figure 2On the lower surface of the guide frame 4, driving protrusions are respectively provided at positions on both sides of the guide protrusion 3. The driving protrusion can be movably arranged in the mounting groove 2 on the same side of the guide protrusion 3 along the first direction. Power parts (the power parts can be cylinders, etc.) are provided in the mounting grooves 2 on both sides of the guide protrusion 3. The driving protrusion is drivingly connected to the power parts in the mounting grooves 2 where it is located, so that the guide frame 4 is driven by the power parts to move along the guide protrusion 3, so that the rod contacts the cutting machine 8, which not only reduces manual labor, but also improves cutting safety and avoids personal injury.

[0035] In order to ensure the stability of the power component driving the guide frame 4 to move along the guide protrusion 3, the lower surface of the guide frame 4 is tightly fitted with the upper surface of the guide protrusion 3, or the lower surface of the driving protrusion is tightly fitted with the bottom surface of the installation groove 2 where it is located.

[0036] Working principle: the staff can place the alloy rod in advance on the inner side of the fixed limit plate 61 and the movable limit plate 66 above the assembly guide frame 52, and then manually push the screw 64. Under the threaded guidance of the screw groove 63 in the middle of the fixed frame 62 and the movable cooperation of the movable shaft 65 at the end of the screw, the movable limit plate 66 can cooperate with the fixed limit plate 61 under the guidance of the movable groove 68 to clamp and limit the rod. The protective pads 67 on the inner sides of the two plates can further improve the anti-slip property. After the alloy rod is clamped, the staff can rotate the hand-held block 516 to make the transmission rod 515 rotate with the second bevel gear 514, and the first bevel gear 513 meshed with the gear can rotate with the transmission screw 512, and the transmission screw 512 can carry the assembly guide frame 52 and the clamped rod to cooperate with the guide rod 518 for horizontal positioning. During the displacement of the bar, one end of the bar will contact the vertical part of the L-shaped slide 532, and the L-shaped slide 532 will be guided and displaced on one side of the guide frame 4 during the continuous displacement. At this moment, the laser 534 provided at the lower end of the L-shaped slide 532 will be displaced on the scale 54 provided on the processing table 1. Since the vertical position of the emission end of the laser 534 corresponds to the side of the vertical part of the L-shaped slide 532 close to the guide frame 4, the corresponding scale 54 pointed by the laser 534 is the distance of the exposed bar, which is convenient for personnel to determine the point of the bar to be sheared. After the determination is completed, the guide frame 4 moves along the guide protrusion 3 to approach the cutting machine 8. During this process, the cutting machine 8 is turned on. When the bar contacts the shearing piece of the cutting machine 8, the cutting operation of its corresponding point can be achieved. It is portable and practical. After cutting, the bar falls into the accommodation space on the L-shaped slide 532, and moves away from the cutting machine 8 along the guide protrusion 3 with the guide frame 4, so that the cut bar can be safely taken out.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
