[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Examples of embodiments are shown in the accompanying drawings, in which the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be interpreted as limiting the utility model.
[0030] The utility model discloses a feeding structure, please refer to Figures 1 to 6 , including a spline 10, the outer wall of the spline 10 is provided with a first key tooth 11, the spline 10 is provided with a first mounting hole 12, the first key tooth 11 is connected to the feeding component 20, the first mounting hole 12 is connected to the rotating shaft 31 of the power component 30, the feeding component 20 is provided with a second mounting hole 21, the first key tooth 11 is assembled in the second mounting hole 21, and the power component 30 is driven and connected to the feeding component 20 through the spline 10.
[0031] By providing a spline 10 between the feeding component 20 and the power component 30, the rotating shaft 31 of the power component 30 is connected to the first mounting hole 12, and the first key tooth 11 is connected to the second mounting hole 21. The torque generated during the rotation process is distributed at the first mounting hole 12 and the first key tooth 11 of the spline 10. At the same time, due to the setting of the spline 10, the feeding component 20 is farther away from the rotating shaft 31 of the power component 30, resulting in a smaller force on the feeding component 20, so that the feeding component 20 is less prone to damage than the spline 10. The purpose of making the maintenance process simpler is achieved by replacing the spline 10 instead of replacing the feeding component 20. Compared with the prior art, a feeding structure disclosed in the present application can achieve the purpose of easy maintenance.
[0032] It should be noted that the spline 10 is provided with a first mounting hole 12, and the first mounting hole 12 is connected to the rotating shaft 31 of the power component 30. The torque applied to the first mounting hole 12 is the same as the torque applied to the second mounting hole 21. However, since the first mounting hole 12 is closer to the rotating shaft 31, when the feeding component 20 and the spline 10 are made of the same material, the force applied to the first mounting hole 12 is greater and is more prone to damage.
[0033] In addition, in addition to achieving the purpose of easy maintenance, the setting of the spline 10 can also make the connection between the spline 10 and the feeding component 20 more stable. During the rotation process, the spline 10 is not prone to self-rotation and slipping, making the feeding structure more stable during the feeding process.
[0034] It should be noted that the feeding structure can be a rotating feeding structure such as a bolt or a rotating push rod.
[0035] In some embodiments, the feed member 20 and the spline 10 are detachably connected.
[0036] It should be noted that the feeding component 20 and the spline 10 are detachably connected, so that the spline 10 can be easily removed from the feeding component 20, making it more convenient for operators to repair the feeding structure.
[0037] The feeding component 20 and the spline 10 can be disassembled along the axial direction. The feeding component 20 and the spline 10 can also be detachably connected by means of threads or buckles.
[0038] In other embodiments, the feeding component 20 and the spline 10 may also be fixedly connected, for example, by making the first key tooth 11 interference fit with the second mounting hole 21 to achieve a fixed connection, and the spline 10 is pushed out or clamped out of the second mounting hole 21 when maintenance is required.
[0039] In some specific embodiments, please refer to Figures 2 to 5 A second key tooth 22 is disposed in the second mounting hole 21 , and the second key tooth 22 and the first key tooth 11 are engaged with each other.
[0040] Specifically, a second key tooth 22 is provided in the second mounting hole 21, and the second key tooth 22 engages with the first key tooth 11, so that the connection between the spline 10 and the feeding component 20 is tighter and the contact range is larger, achieving a more stable and powerful effect when transmitting torque.
[0041] In some more specific embodiments, the second key teeth 22 and the first key teeth 11 are clearance-fitted.
[0042] Specifically, in order to facilitate the assembly of the feeding component 20 and the spline 10, the clearance between the second key teeth 22 and the first key teeth 11 is made to fit, so that the spline 10 is easily inserted into the second mounting hole 21. The detachable connection between the feeding component 20 and the spline 10 is achieved through the matching relationship between the first key teeth 11 and the second key teeth 22, so as to achieve the purpose of making the structure of the feeding structure simpler, facilitating maintenance and reducing costs.
[0043] For more specific embodiments, please refer to Figures 2 to 5 The number of the second key teeth 22 is less than the number of the first key teeth 11 , and the second key teeth 22 are evenly distributed in the second mounting hole 21 .
[0044] Specifically, the number of the second key teeth 22 is less than the number of the first key teeth 11. The number of the second key teeth 22 can be set according to the maximum torque that the motor can reach. The greater the torque of the motor, the more second key teeth 22 can be set. By reducing the number of second key teeth 22, the manufacturing difficulty of the feeding component 20 can be reduced, making it easier to produce. In addition, the second key teeth 22 are evenly distributed in the second mounting hole 21, so that the force on the multiple second key teeth 22 is more uniform, thereby obtaining a better transmission torque.
[0045] For more specific embodiments, please refer to Figures 2 to 5 The second key tooth 22 is provided with a chamfer, and the chamfer is located at the starting position for assembly of the first key tooth 11 and the second key tooth 22.
[0046] It should be noted that in order to make it easier for the spline 10 to be assembled in the second mounting hole 21, a chamfer is provided on the second key tooth 22 on the second mounting hole 21, so that when the spline 10 is assembled, the spline 10 can be inserted therein at any angle.
[0047] In other embodiments, please refer to Figures 2 to 5 The first key tooth 11 is provided with a chamfer, and the chamfer is located at the starting position of the assembly of the first key tooth 11 and the second key tooth 22. Thus, the spline 10 is easier to be installed in the second mounting hole 21.
[0048] In other embodiments, please refer to Figure 3 The first mounting hole 12 is not provided through the spline 10. Thus, the structural strength of the spline 10 is higher.
[0049] In some embodiments, please refer to Figure 2 and Figure 3 The spline 10 is cylindrical in shape, and the first mounting hole 12 is located at the center axis of the spline 10 .
[0050] It should be noted that, in order to obtain good rotation stability and reduce the vibration and shaking caused by the feeding structure, the shape of the spline 10 is set to be cylindrical, and the first mounting hole 12 is set at the center axis of the spline 10. Obviously, the shape of the spline 10 can also be a polyhedron or a cone.
[0051] In some embodiments, please refer to Figure 2 and Figure 6 The cross-section of the first mounting hole 12 is D-shaped, and the rotating shaft 31 of the power component 30 is assembled in the first mounting hole and cooperates with each other.
[0052] Specifically, in order to prevent the first mounting hole 12 and the power component 30 from rotating relative to each other, the interface shape of the first mounting hole 12 is set to a D shape, and the rotating shaft 31 and the first mounting hole 12 cooperate with each other. On the one hand, the D-shaped first mounting hole 12 has higher strength, and on the other hand, it is more stable during rotation.
[0053] It should be noted that the power component 30 can be a motor, or can be driven manually. For example, the rotating shaft 31 is connected to a crank, and the operator can rotate the crank to rotate the rotating shaft 31, thereby driving the feeding component 20 to rotate.
[0054] In some embodiments, the first mounting hole 12 is interference-fitted with the rotating shaft 31 of the power component 30 .
[0055] Specifically, the first mounting hole 12 and the rotating shaft 31 are interference fit, and the rotating shaft 31 can be firmly fixed on the spline 10 during the interference fit, and the two are not likely to fall off, which is also more conducive to the transmission of torque during rotation.
[0056] In some embodiments, a plastic piece is disposed at the head of the rotating shaft 31 of the power component 30 , and the plastic piece is assembled with the first mounting hole 12 .
[0057] It should be noted that the head of the rotating shaft 31 is provided with a plastic part, and the plastic part is assembled with the first mounting hole. The plastic part has a lower strength than the metal part. Therefore, when the torque of the rotating shaft 31 is too large, the plastic part will be deformed first. Therefore, the feeding structure can be repaired by replacing the plastic part. It should be noted that the strength of the plastic part should be selected according to the power required for the feeding component 20 to run, so as to meet its basic use requirements.
[0058] Preferably, the plastic part is sleeved on the rotating shaft 31 and connected with the spline 10, so that it is more convenient when it is repaired and replaced. In addition, in other embodiments, the entire rotating shaft 31 can also be a plastic part.
