Description

Technical Field

[0001] This utility model relates to the field of flange technology, and in particular to a detachable multi-purpose flange end cap. Background Technology

[0002] There are generally two designs for the front cover of a motor, one of which is shown in the attached image. Figure 7 The standard end cap without flange shown is one type as attached. Figure 8 The image shows a flanged end cap with a flange. The two types of end caps have largely the same shape; the flanged end cap is essentially a standard end cap with a flange added around it. Currently, producing both types of end caps requires two completely separate molds, which are costly. Therefore, we are considering optimizing the end cap structure. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a detachable multi-purpose flange end cover, on which the flange can be removed to adapt to different shape requirements.

[0004] Technical Solution: To achieve the above objectives, this utility model provides a detachable multi-purpose flange end cover, comprising a detachably connected end cover and a flange; an annular sleeve is connected to the inner ring of the flange, the inner contour shape of the annular sleeve being consistent with the shape of the outer circumferential surface of the end cover; a retaining plate is also provided inside the annular sleeve, and when the annular sleeve slides on the outer circumferential surface of the end cover, the retaining plate can move to fit against the outer end face of the end cover; a locking mechanism is also provided between the retaining plate and the end cover, the locking mechanism being able to lock the retaining plate onto the outer end face of the end cover.

[0005] Furthermore, the locking mechanism includes several locking bolts, several through holes are provided on the clamping plate, and several threaded holes are provided on the outer end face of the end cover; the locking bolts pass through the through holes and engage with the threaded holes to lock the clamping plate on the outer end face of the end cover.

[0006] Furthermore, the threaded hole is a blind hole; several protrusions are provided on the side of the end cover away from the flange, and the opening position of the threaded hole on the end cover corresponds to the protrusions.

[0007] Furthermore, the protrusion has an external thread structure, and a nut is threadedly connected to the protrusion. When the nut is installed on the protrusion, it presses against the threaded hole.

[0008] Furthermore, the card plate is annular, and several through holes are distributed circumferentially on the card plate.

[0009] Furthermore, a plurality of first reinforcing ribs are circumferentially distributed between the clamping plate and the inner ring of the flange, and a plurality of second reinforcing ribs are circumferentially distributed between the annular ferrule and the flange.

[0010] Furthermore, the through hole is centrally located between two adjacent first reinforcing ribs, and the inner ring of the flange expands away from the end cover.

[0011] Furthermore, the outer end face of the end cap is divided into an inner heat dissipation area and an outer connection area. The inner heat dissipation area is provided with several heat dissipation fins, and the outer connection area is annular and surrounds the outer side of the inner heat dissipation area. Several threaded holes are distributed circumferentially on the outer connection area, and the clamping plate is correspondingly attached to the outer connection area.

[0012] Furthermore, the outer peripheral surface of the end cap is provided with an annular stepped groove, and the annular sleeve is correspondingly fitted onto the annular stepped groove.

[0013] Beneficial effects: The beneficial effects of this detachable multi-purpose flange end cap are as follows:

[0014] 1) The end cover and the flange are detachably connected by locking bolts. When the flange is not installed on the end cover, it can replace the traditional standard end cover. When the flange is installed on the end cover, it can replace the traditional flange end cover. Therefore, it is not necessary to make two separate molds, saving mold opening costs.

[0015] 2) The end cap and flange are detachably connected by bolts and threaded holes. The end cap has a protrusion opposite to the threaded hole, making the threaded hole a blind hole to ensure the waterproof and dustproof performance of the end cap. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] As attached Figures 1 to 8 The aforementioned detachable multi-purpose flange end cap includes a detachably connected end cap 1 and flange 2. A plurality of flange 2 holes are circumferentially distributed on the flange 2. An annular retaining sleeve 3 is connected to the inner ring of the flange 2, and the inner contour shape of the annular retaining sleeve 3 is consistent with the shape of the outer circumferential surface of the end cap 1. A retaining plate 4 is also provided inside the annular retaining sleeve 3. When the annular retaining sleeve 3 is fitted onto the outer circumferential surface of the end cap 1, the annular retaining sleeve 3 can slide relative to the end cap 1. When the annular retaining sleeve 3 slides onto the outer circumferential surface of the end cap 1, the retaining plate 4 can move to fit against the outer end face of the end cap 1. A locking mechanism is also provided between the retaining plate 4 and the end cap 1, which can lock the retaining plate 4 onto the outer end face of the end cap 1, thereby locking the end cap 1 and flange 2 together.

[0026] The structure of a traditional standard end cap is shown in the attached figure. Figure 7 As shown, the mold cost for a traditional standard end cap is approximately 10,000 yuan. The structure of a traditional flange end cap is shown in the attached figure. Figure 8 As shown, the mold opening cost for a traditional flange end cap is approximately 15,000 yuan, a significant price difference. Opening two molds would cost 25,000 yuan, which is also quite expensive. Therefore, this utility model of a multi-purpose flange end cap was designed. When the end cap 1 is not fitted with flange 2, it can replace a traditional standard end cap; when the end cap 1 is fitted with flange 2, it can replace a traditional flange end cap. Thus, it eliminates the need for two separate sets of molds.

[0027] This utility model's multi-purpose flange end cap has a simple structure and reasonable design. The split flange 2 reduces reliance on integral forging or casting processes, lowering material waste and production costs. Because it is detachable, it occupies less space during transportation and storage, reducing logistics costs. Adding or removing flange 2 is also convenient if needed temporarily. Overall, it reduces mold opening costs, lowers material transportation and storage costs, and also facilitates modifications to meet different customer needs.

[0028] Specifically, the locking mechanism includes several locking bolts 5, several through holes 8 on the clamping plate 4, and several threaded holes 6 on the outer end face of the end cover 1. The locking bolts 5 pass through the through holes 8 and engage with the threaded holes 6 to lock the clamping plate 4 onto the outer end face of the end cover 1. A washer is provided between the locking bolts 5 and the clamping plate 4 to improve the locking effect of the locking bolts 5 on the clamping plate 4. Furthermore, as shown in the attached... Figure 2 and 4 As shown, several protrusions 7 are provided on the side of the end cover 1 away from the flange 2. The threaded holes 6 on the end cover 1 are positioned corresponding to the protrusions 7, thus making the threaded holes 6 blind holes. The protrusions 7 ensure the waterproof and dustproof performance of the end cover 1, ensure that no through holes appear after the end cover 1 and flange 2 are assembled, and thus ensure that the overall protection level of the equipment is not reduced.

[0029] The protruding post 7 has an external thread structure, and a nut 15 is threadedly connected to the protruding post 7. The nut 15 can be installed as needed. If the flange 2 will not be removed after being installed on the end cover 1, then after the bolt is screwed into the threaded hole 6, the nut 15 is installed on the protruding post 7. When the nut 15 is installed on the protruding post 7, it exerts a certain squeezing effect on the threaded hole 6, making it difficult for the bolt to loosen within the threaded hole 6, thus maintaining a tight connection between the end cover 1 and the flange 2. If it is determined that the flange 2 may be removed from the end cover 1 later, then the nut 15 does not need to be installed, to avoid the presence of the nut 15 making it difficult for the bolt to be screwed into the threaded hole 6. Furthermore, if the threaded hole 6 mistakenly penetrates the protruding post 7 during machining, resulting in a through hole, then installing the nut 15 on the protruding post 7 can serve as a remedial measure to seal the threaded hole 6 that penetrates the protruding post 7.

[0030] The card plate 4 is annular, and several through holes 8 are distributed circumferentially on the card plate 4. Correspondingly, several threaded holes 6 are also distributed circumferentially on the outer end face of the end cap 1.

[0031] As attached Figure 5 As shown in the figure, several first reinforcing ribs 9 are circumferentially distributed between the inner ring of the clamping plate 4 and the flange 2; as shown in the attached figure. Figure 6 As shown, several second reinforcing ribs 10 are circumferentially distributed between the annular ferrule 3 and the flange 2 to enhance the structural strength of the flange 2. The positions of the several first reinforcing ribs 9 and the several second reinforcing ribs 10 on both sides of the flange 2 correspond one-to-one. The through hole 8 is centrally located between two adjacent first reinforcing ribs 9, and the inner ring of the flange 2 expands away from the end cover 1 to facilitate tightening the bolts.

[0032] The outer end face of the end cover 1 is divided into an inner heat dissipation area 11 and an outer connection area 12. The inner heat dissipation area 11 contains several heat sinks 13, and the inner heat insulation area has a central hole through which the motor shaft passes when the end cover 1 is installed on the motor. The outer connection area 12 is annular and surrounds the outer side of the inner heat dissipation area 11. Several threaded holes 6 are circumferentially distributed on the outer connection area 12, and a retaining plate 4 is correspondingly attached to the outer connection area 12.

[0033] As attached Figure 2 As shown, an annular stepped groove 14 is provided on the outer peripheral surface of the end cap 1, and the annular sleeve 3 is fitted onto the annular stepped groove 14.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
