[0003] The Chinese patent with publication number CN218351276U discloses a cutting device for coil production cutting, and its technical points are: it includes a fixed box, a fixing mechanism is arranged inside the fixed box, the fixing mechanism includes a bidirectional threaded rod rotatably connected to the inner wall of the fixed box, the outer surface of the bidirectional threaded rod is threadedly connected to two symmetrical moving plates, the inner wall of the fixed box is fixedly connected to a fixing rod, the fixing rod passes through the moving plate and is slidably connected to the moving plate, and is fixedly clamped by setting two symmetrical arc plates to contact with the coil.

[0004] In the above scheme, the coil is clamped and fixed by the curved plate during cutting through the setting of the fixing box and the fixing mechanism, thereby ensuring the stable cutting work. However, the scheme uses the curved plate to apply pressure to the middle coil from both sides to squeeze and fix the coil by friction. After long-term use, the surface of the curved plate in contact with the coil will become smooth due to long-term extrusion and wear, and when the coil is placed horizontally, the pressure from both sides may cause the annular coil to be deformed, affecting the use of the coil.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a convenient coil cutting device, which is convenient for fixing the coil position and expands the scope of applicable coils.

DETAILED DESCRIPTION

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment: Convenient coil cutting device, such as Figure 1-Figure 3 As shown, it includes a support frame 1, a cutting assembly 2 is arranged above the support frame 1, a rotating shaft 11 is welded to the bottom end of the support frame 1, an end of the rotating shaft 11 away from the connection with the support frame 1 is rotatably connected to an operating table 12, the operating table 12 which can rotate relative to the rotating shaft 11 is convenient for adjusting the coil cutting angle, a clamping member 3 for clamping the coil is slidably connected to the operating table 12, the design of the clamping member 3 ensures that the coil on the operating table 12 will not deviate during the cutting process, thereby increasing the cutting accuracy, a limiting member 6 is rotatably connected to the rotating shaft 11, the limiting member 6 is slidably connected to the clamping member 3 and is used to limit the clamping member 3 from sliding in a direction inclined to the operating table 12, and the limiting member A transmission member 5 is provided on the rotating shaft 11 at the lower end of 6, and a connecting rod 7 is provided between the transmission member 5 and the clamping member 3. The two ends of the connecting rod 7 are hinged to the transmission member 5 and the clamping member 3 respectively. This structure enables the clamping member 3 to be displaced relative to the limit member 6 through the connecting rod 7 when the transmission member 5 slides up and down relative to the rotating shaft 11. The structural design is simple and reasonable. The transmission member 5 is connected to a force-applying member 4 when it rotates away from the connecting rod 7. Continuous force applied to the force-applying member 4 can drive the clamping member 3 to move in a direction inclined to the operating table 12. The utility model applies pressure from top to bottom to the coil to be cut by the clamping member 3 to fix the coil, while preventing the side of the circular coil from being squeezed and deformed to affect its use.

[0020] like Figure 1-Figure 3 As shown, the rotating shaft 11 is provided with an annular groove, and the transmission member 5 is composed of a transmission cylinder sleeved outside the rotating shaft 11 and located in the annular groove. An elastic member 51 is provided between the transmission cylinder and the upper groove surface of the annular groove. The elastic member 51 is composed of a spring coil. After the pressure on the force-applying member 4 stops, under the action of the elastic force of the elastic member 51, the transmission member 5 is driven to move along the bottom direction of the support frame 1 under the rotating shaft 11, and the clamping member 3 is driven to shrink along the limit member 6 to complete the fixation of the coil, so that the coil is fixed at the center of the operating table 12. The structural design is simple and reasonable.

[0021] like Figure 1-Figure 3 As shown, the clamping member 3 is composed of a sliding rod 32 with a sliding groove and a pressing rod 31 welded to the sliding rod 32. The pressing rod 31 is arranged parallel to the rotating shaft 11, and the sliding rod 32 is arranged inclined to the pressing rod 31. The inclination angles of the pressing rod 31 and the sliding rod 32 are complementary to the inclination angles of the limit member 6 and the rotating shaft 11. The operating table 12 is provided with a displacement groove that can accommodate the displacement of the pressing rod 31. This structure ensures that the pressing rod 31 can approach or move away from the operating table 12 in a direction inclined to the operating table 12. When moving away, it is convenient to place the coil. When approaching, the coil can be fixed at the center of the operating table 12, which is convenient for cutting the coil.

[0022] like Figure 1-Figure 3 As shown, the force-applying member 4 is composed of a connecting ring 41, a telescopic rod 42 and a pedal 43. The connecting ring 41 is rotatably connected to the lower end surface of the transmission cylinder. The telescopic rod 42 is composed of a first slide bar and a second slide bar. The first slide bar is welded to the connecting ring 41, and the second slide bar is welded to the pedal 43. A rotating frame 13 is fixedly connected to the support frame 1, and the second slide bar is rotatably connected to the rotating frame 13. This structure allows the force-applying member 4 to rotate around the rotating frame 13 as the axis. The farthest distance between the pedal 43 and the rotating frame 13 is greater than the farthest distance between the connecting ring 41 and the rotating frame 13. This structure forms a labor-saving lever, so that the operator can use less force to move the clamping member 3 away from the operating table 12 when using the device, thereby facilitating the insertion of the coil.

[0023] Working principle: Continue to apply downward force to the pedal 43. At this time, the transmission cylinder is tilted up through the telescopic rod 42 and the connecting ring 41, and the transmission cylinder slides upward relative to the rotating shaft 11, driving the sliding rod 32 on the clamping member 3 to move along the limit member 6, and driving the lower pressure rod 31 to move in the displacement groove away from the center of the operating table 12. At this time, the clamping member 3 forms a space for placing the coil, and the coil is placed on the operating table 12 between the clamping members 3. Although the force is canceled, the elastic member 51 sleeved on the rotating shaft 11 drives the clamping member 3 to recover under the action of the elastic force, and the lower pressure rod 31 presses the coil, giving the coil a downward force from top to bottom, fixing the coil while avoiding deformation of the circular coil squeezed from the side, which affects its use. The utility model has the characteristics of simple structure and convenient use.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
