Description

Technical Field

[0001] The utility model relates to the technical field of motors, and specifically relates to a mounting and fixing structure for an arc-shaped heat dissipation plate of a steel plate motor base. Background Art

[0002] Most of the existing motor casings are obtained by pressure casting after melting aluminum alloy. Their comprehensive mechanical strength is poor, and their creep characteristics will lead to a reduction in the overall performance and transmission accuracy of the motor. Moreover, the casting industry is a high-energy-consuming and highly polluting industry. A large amount of pollutants such as waste gas, waste water, and solid waste will be generated during the casting process, and a large amount of energy will also be consumed.

[0003] Our company has previously developed and designed various motor casings made of steel plate stamping to solve the above problems. However, most of the heat dissipation fins in such motor casings made of steel plate stamping are made of steel plate stamping and then welded to the steel plate cylinder of the motor. This inevitably leaves gaps between the heat dissipation fins and the steel plate cylinder, 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 accompanying drawings of its specification, four heat dissipation fins are provided on the outer side of the steel plate cylinder. The span of a single heat dissipation fin is close to 90 degrees. Due to the different thermal expansion coefficients of the aluminum heat dissipation fin and the steel plate cylinder, it is extremely easy to cause problems such as thermal expansion deformation and翘起 suspension of the heat dissipation fin. Once there is a gap between the heat dissipation fin and the steel plate cylinder, it will inevitably affect the heat conduction effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mounting and fixing structure for an arc-shaped heat dissipation plate of a steel plate motor base to solve the above-mentioned defects in the prior art.

[0006] A mounting and fixing structure for an arc-shaped heat dissipation plate of a steel plate motor base includes a steel plate cylinder. A number of pairs of arc-shaped heat dissipation plates are evenly distributed circumferentially on the steel plate cylinder. A number of L-shaped hooks are punched out at the adjacent edges of each pair of arc-shaped heat dissipation plates. A "U"-shaped steel plate stamping strip is provided between each pair of arc-shaped heat dissipation plates, and the steel plate stamping strip is welded and fixed to the outer wall of the steel plate cylinder. A number of rectangular process gaps are punched out on both sides of the steel plate stamping strip. The hooks are inserted into the adjacent process gaps. Steel plate stamping plates are symmetrically provided on both sides of each pair of arc-shaped heat dissipation plates, and the steel plate stamping plates are welded and fixed to the outer wall of the steel plate cylinder. A number of "ㄣ"-shaped buckle blocks are fixedly connected to the steel plate stamping plates. The separated edges of the arc-shaped heat dissipation plates are clamped in the gaps between the adjacent steel plate stamping plates and the buckle blocks.

[0007] Preferably, the thickness of the heat dissipation ribs of the arc-shaped heat dissipation plate is less than the width of the gap between the steel plate stamping plate and the buckle block.

[0008] Preferably, a reinforcing rib is welded and fixed in the center of the outer wall of each steel plate stamping strip.

[0009] Preferably, heat-conducting filling glue is filled between the arc-shaped heat dissipation plate and the steel plate cylinder.

[0010] Preferably, a lifting nut is welded and fixed on the outer wall of each steel plate stamping strip, and the lifting nuts are all located in the middle of the steel plate cylinder.

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

[0012] The span of the single curved heat sink in this application is less than 45 degrees, making it less likely to cause the curved heat sink to deform due to thermal expansion and become warped and suspended. Furthermore, each pair of curved heat sinks is secured to the outside of the steel cylinder by means of a process notch on the steel stamping strip and a snap block on the steel stamping plate. Thermally conductive adhesive is then filled between the steel cylinder and the curved heat sink. This prevents the curved heat sink from being fixed and prevents any gaps between the steel cylinder and the curved heat sink, effectively improving thermal conductivity and heat dissipation capabilities. This eliminates the high-frequency vibration and friction generated by the gap between the steel cylinder and the curved heat sink. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] As shown Figures 1 to 5 in the figure, an installation and fixing structure of an arc-shaped heat dissipation plate for a steel plate motor base includes a steel plate cylinder body 10. A number of pairs of arc-shaped heat dissipation plates 11 are circumferentially and evenly distributed on the steel plate cylinder body 10. A number of L-shaped hooks 12 are punched out at the adjacent edges of each pair of arc-shaped heat dissipation plates 11. A U-shaped steel plate stamping strip 13 is provided between each pair of arc-shaped heat dissipation plates 11, and the steel plate stamping strip 13 is welded and fixed to the outer wall of the steel plate cylinder body 10. A number of rectangular process notches 13a are punched out on both sides of the steel plate stamping strip 13, and the hooks 12 are inserted into the adjacent process notches 13a. Steel plate stamping plates 14 are symmetrically provided on both sides of each pair of arc-shaped heat dissipation plates 11, and the steel plate stamping plates 14 are welded and fixed to the outer wall of the steel plate cylinder body 10. A number of L-shaped buckle blocks 15 are fixedly connected to the steel plate stamping plates 14, and the separated edges of the arc-shaped heat dissipation plates 11 are clamped in the gap between the adjacent steel plate stamping plates 14 and the buckle blocks 15. The adjacent edges of each pair of arc-shaped heat dissipation plates 11 are inserted and matched through the hooks 12 and the process notches 13a on the steel plate stamping strip 13, and the separated edges of each pair of arc-shaped heat dissipation plates 11 are clamped and matched with the buckle blocks 15 on the steel plate stamping plates 14, so as to fix the arc-shaped heat dissipation plates 11 to the outside of the steel plate cylinder body 10.

[0022] In this embodiment, the thickness of the heat dissipation ribs of the arc-shaped heat dissipation plate 11 is less than the gap width between the steel plate stamping plate 14 and the buckle block 15. This gap should leave a telescopic amount for the thermal expansion and contraction deformation of the aluminum arc-shaped heat dissipation plate 11.

[0023] In this embodiment, a reinforcing rib 130 is centrally welded and fixed on the outer wall of each steel plate stamping strip 13. Through the reinforcing rib 130, the rigid strength requirement of the steel plate stamping strip 1 is strengthened, and further the rigid strength requirement of the steel plate cylinder body 10 is strengthened.

[0024] In this embodiment, a heat-conducting filling adhesive 16 is filled between the arc-shaped heat dissipation plate 11 and the steel plate cylinder body 10. The heat-conducting filling adhesive 16 is used to fill the gap between the arc-shaped heat dissipation plate 11 and the steel plate cylinder body 10 to improve the heat-conducting ability.

[0025] In this embodiment, a lifting nut 17 is welded and fixed on the outer wall of each steel plate stamping strip 13, and the lifting nuts 17 are all located at the middle position of the steel plate cylinder body 10. The lifting nuts 17 can be used for lifting the base of the steel plate motor.

[0026] In this embodiment, the span of a single curved heat sink 11 is less than 45 degrees, which is less likely to cause the curved heat sink 11 to deform due to thermal expansion and become suspended in the air. In addition, each pair of curved heat sinks 11 is fixed to the outside of the steel cylinder 10 by means of a process notch 13a on the steel stamping strip 13 and a snap block 15 on the steel stamping plate 14. A thermally conductive filler 16 is filled between the steel cylinder 10 and the curved heat sink 11. This does not affect the fixing effect of the curved heat sink 11, but also avoids leaving a gap between the steel cylinder 10 and the curved heat sink 11, effectively improving the thermal conductivity and heat dissipation capacity, thereby eliminating the high-frequency vibration and friction generated by the gap between the steel cylinder 10 and the curved heat sink 11.

[0027] Therefore, the embodiments disclosed above are only illustrative in all respects 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.
