Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor base with a steel plate combined structure replacing aluminum alloy die-casting. Background Art

[0002] Most of the existing motor housings are made by pressure casting after melting aluminum alloy. They have poor comprehensive mechanical strength and their creep characteristics will lead to reduced overall motor performance and transmission accuracy. In addition, the casting industry is a high-energy consumption and high-pollution industry. The casting process will generate a large amount of pollutants such as waste gas, wastewater, and solid waste, and will also consume a lot of energy.

[0003] Our company has previously developed and designed a variety of steel stamping motor housings to solve the above problems. However, the heat sinks in these steel stamping motor housings are mostly stamped from steel plates and then welded to the motor barrel, which inevitably leaves a gap between the heat sink and the barrel, so the heat conduction effect is poor.

[0004] Application No. 202310080886.4 discloses a manufacturing process for a steel plate structure motor base. According to the attached drawings in its specification, four heat sinks are provided on the outside of the steel plate cylinder. The span of a single heat sink is less than 90 degrees. The aluminum heat sink and the steel cylinder have different thermal expansion coefficients, which can easily lead to the heat sink deforming due to thermal expansion and becoming suspended in the air. Once there is a gap between the heat sink and the cylinder, it will inevitably affect the heat conduction effect. Summary of the invention

[0005] The purpose of the utility model is to provide a motor base of a steel plate combined structure which can replace the aluminum alloy die-casting, so as to solve the above-mentioned defects caused by the prior art.

[0006] A motor base with a steel plate composite structure that replaces aluminum alloy die-casting, includes a cylinder, a plurality of heat sinks are provided on the outer side of the cylinder, each heat sink includes two heat sinks, and a fixing component is provided between the two heat sinks, the fixing component includes a fixing seat welded to the outer wall of the cylinder, a plurality of clips are welded on the left and right sides of the fixing seat and are clamped to the inner edges of adjacent heat sinks, a fixing plate is provided on the left and right sides of each heat sink and is welded to the outer wall of the cylinder, a plurality of clips are welded on the fixing plate and are clamped to the outer edges of adjacent heat sinks, and a thermal conductive filling glue is filled between the cylinder and each heat sink.

[0007] Preferably, a pair of nameplate brackets are welded symmetrically on the upper part of the cylinder.

[0008] Preferably, a junction box is welded in the center of the upper portion of the cylinder.

[0009] Preferably, a plurality of lifting blocks are welded to the outer side of the cylinder.

[0010] Preferably, both ends of the cylinder are provided with limiting rings.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] The single heat sink in the present application is composed of a fixed component and two heat sinks, so that the span of the single heat sink is less than 45 degrees, which is not easy to cause the heat sink to expand and deform due to heat and become suspended in the air. In addition, the heat sink is fixed to the outside of the cylinder through the snap 1 on the fixing seat and the snap 2 on the fixing plate, and the heat conductive filling glue is filled between the cylinder and the heat sink, which does not affect the fixing effect of the heat sink and can avoid leaving a gap between the cylinder and the heat sink, effectively improving the heat conduction effect and enhancing the heat dissipation capacity, thereby eliminating the high-frequency vibration and friction between the cylinder and the heat sink due to the gap.

[0022] In this embodiment, a pair of nameplate brackets 6 are symmetrically welded to the upper part of the cylinder 1. The nameplate brackets 6 are used to install the motor nameplate.

[0023] In this embodiment, a junction box 7 is welded in the center of the upper part of the cylinder 1. The junction box 7 is used to connect and protect the wires.

[0024] In this embodiment, a plurality of lifting blocks 8 are welded to the outer side of the cylinder 1. The lifting blocks 8 are used to lift the motor base.

[0025] In this embodiment, both ends of the cylinder 1 are provided with a limiting ring 9. The limiting ring 9 is used to position the heat sink 2 axially.

[0026] In this embodiment, a pair of feet are fixed symmetrically on the lower part of the cylinder 1. The feet are used to meet the needs of horizontal installation of the motor base.

[0027] In this embodiment, the heat sink 2 is formed by aluminum extrusion, and the inner wall of the heat sink 2 is provided with expansion grooves at each fin position to overcome the problem of thermal expansion and contraction, thereby solving the technical problem that the heat sink 2 made of aluminum and the cylinder 1 made of steel have different thermal expansion coefficients, causing the heat sink 2 to expand and deform and become suspended in the air.

[0028] The assembly process of this steel plate composite structure motor frame that replaces aluminum alloy die-casting:

[0029] First, a pair of limiting rings 9 are welded to the two ports of the cylinder 1, and then the fixing seat 31 is welded to the outer wall of the cylinder 1, and the inner edge of the heat sink 2 is clamped by the buckle 1 32 on the fixing seat 31, and then the fixing plate 4 is welded to the outer wall of the cylinder 1, and the outer edge of the heat sink 2 is clamped by the buckle 2 41 on the fixing plate 4. Before clamping the heat sink 2, a thermal conductive filling glue is pre-coated on the inner wall of the heat sink 2.

[0030] In summary, the single heat sink in the present application is composed of a fixing assembly 3 and two heat sinks 2, so that the span of the single heat sink 2 is less than 45 degrees, which is not easy to cause the heat sink 2 to be deformed due to thermal expansion and tilted and suspended in the air. In addition, the heat sink 2 is fixed to the outside of the cylinder 1 by the snap 1 32 on the fixing seat 31 and the snap 2 41 on the fixing plate 4, and the heat conductive filling glue 5 is filled between the cylinder 1 and the heat sink 2, which does not affect the fixing effect of the heat sink 2, and can avoid leaving a gap between the cylinder 1 and the heat sink 2, effectively improving the heat conduction effect, enhancing the heat dissipation capacity, and thus preventing the high-frequency vibration and friction between the cylinder 1 and the heat sink 2 due to the gap.

[0031] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
