[0002] Cutting machines are widely used in cutting metal, stone, cement products, etc. Saw blades are the main components of cutting machines. As people's requirements for cutting machines increase, saw blades are not only required to have high strength and hardness and good plasticity, but also require saw blades to have a small flatness to ensure the flatness of the cutting surface.

[0003] When a traditional leveling device is leveling a saw blade, a cylindrical part is usually pre-fixed on the placement plate. When placing the saw blade, the center inner ring of the saw blade is placed on the outside of the cylindrical part to complete the fixation. However, the center inner rings of saw blades of different sizes often have different sizes. When the traditional fixing method is used to fix saw blades of different sizes, the cylindrical part needs to be replaced again, which is inconvenient to operate and reduces the applicability of the device.

[0004] Therefore, in order to solve the above problems, a saw blade base leveling device is proposed. Utility Model Content

[0027] Example:

[0028] See also Figure 1 - Figure 4A saw blade base leveling device includes a workbench 1 and a frame 2. The frame 2 is fixedly connected to the top of the workbench 1. A placement disk 3 is fixedly connected to the top surface of the workbench 1. An expansion clamping mechanism 4 is arranged inside the placement disk 3. The expansion clamping mechanism 4 includes a fixed ring 41 fixedly connected to the top surface of the workbench 1 and a rotating gear ring 42 rotatably connected to the top surface of the workbench 1. The rotating gear ring 42 is arranged inside the fixed ring 41. The inner ring surface of the rotating gear ring 42 is a tooth surface. Four evenly distributed gears 43 are meshed on the inner ring surface of the rotating gear ring 42. The bottoms of the four gears 43 are rotatably connected to the top surface of the workbench 1. One side of the four gears 43 is meshed with a rack 44. The top surfaces of the four racks 44 are fixedly provided with abutment components 45. A cross groove 31 is opened on the top surface of the placement disk 3. The four abutment components 45 are slidably arranged inside the cross groove 31.

[0029] Specifically, the abutment assembly 45 includes a fixed rod 451 fixedly connected to the top surface of the rack 44, the outside of the fixed rod 451 is slidably connected to a movable sleeve 452, the top of the fixed rod 451 is fixedly connected to a spring 453, and the top of the spring 453 is fixedly connected to the top surface of the inner wall of the movable sleeve 452.

[0030] Specifically, one end of the four racks 44 away from the center of the rotating gear ring 42 is fixedly connected to the limiting slider 46 , and four sliding grooves 411 are formed through the outer edge of the fixed ring 41 . The four limiting sliders 46 are slidably connected inside the four sliding grooves 411 .

[0031] Specifically, a hydraulic cylinder 5 is fixedly disposed inside the placement plate 3 , and one end of a limiting slider 46 away from the center of the rotating gear ring 42 is fixedly connected to the telescopic end of the hydraulic cylinder 5 .

[0032] In this solution, the hydraulic cylinder 5 controls the limit slider 46 to make the rack 44 slide, thereby driving the gear 43 to rotate. When the gear 43 rotates, the rotating gear ring 42 will also rotate, and the rotating gear ring 42 drives the other three gears 43 to rotate, so that the other three racks 44 and the rack 44 connected to the hydraulic cylinder 5 make the same movement, and the four racks 44 will move closer to or away from the center of the rotating gear ring 42, thereby adjusting the positions of the four abutment assemblies 45, and the four abutment assemblies 45 will slide in the cross groove 31 to adapt to the inner rings of saw blades of different sizes. The four movable sleeves 452 are higher than a part of the cross groove 31 and abut against the inner ring of the saw blade, and at the same time cooperate with the pressure of the hydraulic cylinder 5 to achieve the fixing effect of the saw blade. What's more, the sizes of the four movable sleeves 452 are compatible with the size of the fixed rod 451, and the movable sleeves 452 can only slide on the fixed rod 451 without bending.

[0033] See also Figure 1 A hydraulic device 6 is fixedly connected to the top of the frame 2, and the telescopic end of the hydraulic device 6 passes through the top surface of the frame 2 and is fixedly connected to a leveling plate 7.

[0034] Specifically, two guide columns 8 are fixedly connected to the top surface of the workbench 1 , and two guide sliders 71 are symmetrically fixedly connected to the outer edge of the leveling plate 7 . The two guide sliders 71 penetrate through and are slidably connected to the outside of the two guide columns 8 .

[0035] In the present scheme, when the saw blade is quenched and leveled, the staff places the saw blade on the placement disk 3 and fixes it with the expansion clamping mechanism 4, and then turns on the hydraulic equipment 6 to lower the leveling disk 7. After the leveling disk 7 is lowered, it cooperates with the placement disk 3 to squeeze and level the saw blade. During the descent of the leveling disk 7, the leveling disk 7 will first contact the movable sleeve 452, and the movable sleeve 452 will squeeze the spring 453 after being compressed, so that the overall length of the abutment assembly 45 becomes smaller, until the top surface of the movable sleeve 452 and the top surface of the saw blade are at the same height, and then the leveling disk 7 continues to press down to start the leveling work. After the leveling is completed, the spring 453 releases the elastic force to bounce the movable sleeve 452 back to its original position, and the guide column 8 and the guide slider 71 play a guiding and limiting role for the leveling disk 7, which can effectively prevent the leveling disk 7 from tilting during the descent.

[0036] Working principle: During leveling, the staff first turns on the hydraulic cylinder 5 to bring the four abutment components 45 close to the minimum distance, then aligns the quenched inner ring of the saw blade with the four abutment components 45 as a whole and passes through, and then the saw blade is placed on the placement plate 3. The staff then turns on the hydraulic cylinder 5 to drive the four racks 44 to expand outward, so that the four movable sleeves 452 press the inner ring of the saw blade tightly, thereby completing the fixation of the saw blade, and then the staff turns on the hydraulic equipment 6 to lower the leveling plate 7, and level the saw blade by squeezing between the leveling plate 7 and the placement plate 3.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
