[0036] like Figure 1 and Figure 2 As shown, according to an embodiment of the present application, a single-barrel vertical motor base is proposed, comprising: a barrel 10, a first end plate 11, a second end plate 12 and a tie rod 13; the first end plate 11 is coaxially arranged with the barrel 10, and the first end plate 11 is connected to the first end of the barrel 10; the second end plate 12 is annular, the second end plate 12 is coaxially arranged with the barrel 10, and the second end plate 12 is connected to the second end of the barrel 10; the tie rod 13 is evenly arranged on the outer wall of the barrel 10 along the circumference of the barrel 10, the tie rod 13 is connected to the end face of the first end plate 11, and the tie rod 13 is connected to the outer wall of the second end plate 12.
[0037] The single-cylinder vertical motor base provided in the embodiment of the present application includes a barrel 10, a first end plate 11, a second end plate 12 and a tie rod 13. The base adopts a single-cylinder structure with a small number of connection points, which ensures the overall structural rigidity and stability of the base, helps to reduce vibration and improve the operating efficiency of the motor; moreover, the overall structure of the base is simple and compact, and has high symmetry and integrity, which reduces the number of components and reduces the manufacturing cost and assembly difficulty of the base. By respectively welding the first end plate 11 and the second end plate 12 at the two ends of the barrel 10, the machine base is supported and fixed, which is convenient for the upright installation of the machine base, and the radial rigidity of the machine base is enhanced to ensure the strength and stability of the machine base after installation; a tie rod 13 is arranged on the outer wall of the barrel 10, and the tie rod 13 is connected to the end face of the first end plate 11, and the tie rod 13 is connected to the outer wall of the second end plate 12, so as to increase the connection area between the tie rod 13 and the second end plate 12, improve the connection strength and structural stability between the tie rod 13 and the second end plate 12, improve the ability of the tie rod 13 to resist deformation, and at the same time improve the axial strength of the machine base, so that the overall rigidity of the machine base structure is improved, thereby increasing the natural frequency of the machine base, reducing the electromagnetic noise of the motor, and thus reducing the vibration noise of the motor.
[0038] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the first end plate 11 is welded to the barrel 10; the second end plate 12 is welded to the barrel 10; the tie rod 13 is welded to the outer wall of the barrel 10, the tie rod 13 is welded to the first end plate 11, and the tie rod 13 is welded to the second end plate 12.
[0039] In this technical solution, the barrel 10 and the first end plate 11, as well as the barrel 10 and the second end plate 12 are connected by welding to ensure the stability of the first end plate 11 and the second end plate 12 in supporting and fixing the barrel 10; the tie rod 13 is welded to the barrel 10, the first end plate 11 and the second end plate 12 at the same time, so that the tie rod 13, the barrel 10, the first end plate 11 and the second end plate 12 form a stable integrated structure, and the tie rod 13 is used to improve the overall strength and rigidity of the machine base, thereby improving the natural frequency of the machine base, reducing the transmission of electromagnetic vibration noise, and preventing large vibration noise when the motor is working.
[0040] Furthermore, after the welding connection of the various parts of the machine base is completed, the machine base needs to be treated to eliminate internal stress to improve the structural stability of the machine base, thereby improving the overall strength and durability of the machine base.
[0041] like Figure 1 As shown, in a feasible embodiment, the outer diameter of the second end plate 12 is equal to the outer diameter of the barrel 10 .
[0042] In this technical solution, the second end plate 12 provides support for the barrel 10. The second end plate 12 has the same outer diameter as the barrel 10, so that the barrel 10 can be evenly supported during installation and operation, reducing stress concentration caused by the diameter difference between the second end plate 12 and the barrel 10. At the same time, it is easier to align the base during installation to prevent eccentricity after installation, so as to ensure the balance and operation stability of the motor, and facilitate overall assembly and disassembly, and simple operation.
[0043] like Figure 2 As shown, in a feasible embodiment, the first end plate 11 is circular, and the diameter of the first end plate 11 is greater than the outer diameter of the barrel 10 .
[0044] In this technical solution, the diameter of the first end plate 11 is larger than the outer diameter of the barrel 10. The first end plate 11 increases the fixing surface area of the lower end surface of the base to improve the stability of the base, thereby improving the fixing strength of the base. At the same time, the weight of the motor can be evenly distributed on the first end plate 11, thereby improving the bearing capacity of the first end plate 11, which is beneficial to improving the overall strength and rigidity of the base.
[0045] like Figure 2 As shown, in a feasible embodiment, at least four tie rods 13 are symmetrically arranged on the outer wall of the barrel 10 .
[0046] In this technical solution, the tie rods 13 are symmetrically arranged on the outer wall of the barrel 10 so that the forces resisting deformation of the barrel 10 in all horizontal directions are equal. The axial strength of the base in all horizontal directions is uniformly increased by symmetrically arranging the tie rods 13.
[0047] Furthermore, the tie rods 13 are symmetrically arranged on the outer wall of the barrel 10 with the center of the barrel 10 as the center.
[0048] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the tie rod 13 is arranged parallel to the axis of the barrel 10, and the first end face of the tie rod 13 is flush with the end face of the second end plate 12 away from the first end plate 11; wherein the first end face is the end face of the tie rod 13 away from the first end plate 11.
[0049] In this technical solution, the upper end surface of the tie rod 13 is flush with the upper end surface of the second end surface. On the one hand, it helps to form a uniform stress distribution on the machine base, reduce deformation due to stress concentration or structural damage caused by excessive local stress, and improve the overall rigidity of the machine base. On the other hand, the upper end surface of the tie rod 13 is flush with the upper end surface of the second end surface, which can simplify the processing process and facilitate installation and subsequent maintenance work.
[0050] like Figure 2As shown, in a feasible embodiment, the tensioning rib 13 includes: a rib plate 131 and a reinforcement plate 132; the two rib plates 131 are symmetrically arranged on the outer wall of the barrel 10; the reinforcement plate 132 is arranged perpendicular to the rib plate 131, and the reinforcement plate 132 is connected to the two rib plates 131 at the same time, and the reinforcement plate 132 is located at one end of the rib plate 131 away from the first end plate 11, and the end face of the reinforcement plate 132 away from the first end plate 11 is flush with the first end face.
[0051] In this technical solution, each tie bar 13 includes two rib plates 131. The two rib plates 131 are symmetrically arranged on the barrel 10, so that after the rib plates 131 are welded to the barrel 10, the connection strength between the two rib plates 131 and the barrel 10 is more equal, and thus the ability of the two rib plates 131 to resist deformation is also more equal; and a reinforcement plate 132 is arranged between the two rib plates 131 to support the two rib plates 131, thereby improving the ability of the rib plates 131 to resist deformation, and then improving the stiffness of the tie bar 13 itself, thereby improving the reliability of the tie bar 13 supporting the machine base.
[0052] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the single-cylinder vertical motor base also includes: heat dissipation ribs 14; a plurality of heat dissipation ribs 14 are arranged at equal intervals along the circumference of the barrel 10 between two adjacent tension ribs 13, the heat dissipation ribs 14 are welded to the outer wall of the second end plate 12, and the heat dissipation ribs 14 are welded to the outer wall of the barrel 10.
[0053] In this technical solution, the heat dissipation ribs 14 are welded to the outer walls of the barrel 10 and the second end plate 12 at the same time, that is, the heat dissipation ribs 14 have a sufficient length, which can not only increase the heat dissipation area of the base and enhance the heat dissipation effect of the base, but also serve as a reinforcement structure to improve the rigidity of the connection between the second end plate 12 and the barrel 10; the heat dissipation ribs 14 are arranged at equal intervals between two adjacent tension ribs 13 to ensure the uniformity of the heat dissipation of the base and prevent the base from deformation due to uneven heat dissipation.
[0054] like Figure 1 and Figure 2 As shown, in a feasible implementation manner, the heat dissipation ribs 14 are arranged along the axis of the barrel 10 , and the end surface of the heat dissipation ribs 14 away from the first end plate 11 is flush with the end surface of the second end plate 12 away from the first end plate 11 .
[0055] In this technical solution, the heat dissipation rib 14 is arranged parallel to the axis of the barrel 10 and extends along the length direction of the machine base. On the one hand, it can increase the heat dissipation area of the machine base, improve the heat dissipation efficiency, and prevent the motor from overheating. On the other hand, it can prevent deformation of the machine base due to uneven temperature of the machine base due to different heat dissipation effects, which helps to maintain the structural stability of the machine base. At the same time, the end face of the heat dissipation rib 14 away from the first end plate 11 is flush with the end face of the second end plate 12 away from the first end plate 11, which helps the heat dissipation rib 14 and the upper end face of the second end plate 12 to form a good heat conduction path, so that air can flow smoothly, further promote the heat dissipation of the machine base, thereby improving the heat dissipation efficiency and effect of the whole machine.
[0056] like Figure 1 As shown, in a feasible embodiment, the single-cylinder vertical motor base also includes: a wiring hole 15 and a wiring box seat 16; the wiring hole 15 passes through the barrel 10; the wiring box seat 16 is arranged on the outer wall of the barrel 10, and the tensioning ribs 13 and the heat dissipation ribs 14 are arranged away from the wiring box seat 16.
[0057] In this technical solution, a wiring hole 15 is provided on the base to lead out the wires inside the base; the junction box seat 16 is used to protect the wire connector to ensure the stability and reliability of the line connection.
[0058] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.
[0059] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
