Description

Technical Field

[0001] This utility model relates to the field of water pump manufacturing technology, specifically a novel spin-welded baffle structure. Background Technology

[0002] In the prior art, a Chinese patent with authorization announcement number CN217991276U discloses a rotary friction welding structure, which includes a welding seat and a welding cover. The inner side of the top of the welding seat is provided with a rotary welding rib, and the inner and outer sides of the upper end of the rotary welding rib are inclined to form a lower welding surface. The outer side of the top of the welding seat is provided with an outer baffle plate, and an outer overflow groove is formed between the outer baffle plate and the rotary welding rib. The bottom edge of the welding cover is provided with a rotary welding groove, and the inner and outer sides of the rotary welding groove are inclined to form an upper welding surface. The bottom of the welding cover is provided with an inner baffle plate located inside the rotary welding groove, and an inner overflow groove is formed between the inner baffle plate and the inner wall of the welding seat.

[0003] When the above solution is used, it only blocks the overflow by using inner and outer baffles. When the overflow flows out, the baffle alone is not effective enough. The molten overflow will overflow outward from the gaps along the baffle structure. The effect of blocking the overflow on both the inner and outer sides is limited, which may lead to the overflow leaking out or entering the product cavity, resulting in inconsistent product quality and increasing the labor intensity of subsequent quality inspection. Utility Model Content

[0004] The purpose of this invention is to provide a novel spin welding retaining structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel spin-welding material-blocking structure, comprising an upper shell, a lower shell, and a connecting seat, wherein the upper shell and the connecting seat are interlocked and fixed, and the connecting seat and the connecting seat are rotatably welded and fixed, wherein the lower shell is integrally formed with a connecting ring, an inner retaining ring, and an outer retaining ring on the side facing the connecting seat, wherein the outer retaining ring is disposed on the outside of the connecting ring, and the inner retaining ring is disposed on the inside of the connecting ring, and the connecting seat is provided with a connecting groove, an outer residual material groove, and an inner residual material groove on the side facing the lower shell.

[0006] Preferably, the connecting ring corresponds to the connecting groove, so that after the connecting ring and the connecting groove come into contact, they rotate relative to each other under the drive of the welding fixture, so that the outer retaining ring and the connecting groove rub against each other and fuse. An outer overflow groove is formed between the outer retaining ring and the connecting ring, so that the material overflowing outward during the spin welding of the connecting ring is collected by the outer retaining ring and stored inside the outer overflow groove. An inner overflow groove is formed between the inner retaining ring and the connecting ring, so that the material overflowing inward from the connecting ring is blocked by the inner retaining ring and falls into the inner overflow groove for storage.

[0007] Preferably, an outward protrusion is formed between the connecting groove and the external overflow groove, and the external overflow groove corresponds to the external overflow groove. The overflow material is collected through the cavity formed between the external overflow groove and the external overflow groove to prevent the overflow material from overflowing outward and affecting the appearance of the product.

[0008] Preferably, an inner overflow groove is formed between the connecting ring and the inner retaining ring. The inner overflow groove corresponds to the inner residual material groove. The overflow material generated inside the connecting ring is collected through the inner overflow groove and the inner residual material groove to prevent the overflow material from overflowing from the inner side of the lower housing and the connecting seat. The overflow material falls into the inner residual material groove and the inner overflow groove and cools down, sealing the gap and improving the airtightness.

[0009] Preferably, an outer baffle groove is provided on one side of the connecting seat. The outer baffle groove is located outside the outer overflow groove. The outer baffle groove is adapted to the outer retaining ring. The outer retaining ring and the outer baffle groove cooperate to close the overflow, blocking the overflow inside the overflow groove inside the outer retaining ring. This improves the overflow blocking effect, increases the contact area between the overflow and the lower shell and the connecting seat, and improves the fixing strength of the weld after the molten overflow cools down inside the overflow groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In this application, when the contact area between the connecting ring and the connecting groove melts, the excess material will be squeezed out of the connecting groove and overflow to both the inside and outside of the connecting groove. The overflow flowing to the inside of the connecting groove will fall between the inner overflow trough and the inner residual material trough. The overflow is stored through the cavity between the inner overflow trough and the inner residual material trough, and the overflow is blocked by the inner retaining ring to prevent the overflow from entering the inner cavity of the lower shell. The overflow cools inside the inner residual material trough and the inner overflow trough, sealing the gap and improving the airtightness. The melted overflow increases the contact area with the lower shell and the connecting seat in the cavity. After medical cooling and solidification, it increases the fixing strength of the lower shell and the connecting seat and increases the service life of the product.

[0012] 2. In this application, the overflow material flowing to the outside of the connecting groove falls into the cavity between the outer overflow groove and the outer residual material groove. The outer retaining ring and the outer retaining groove simultaneously block the overflow material, preventing the overflow material from flowing out of the joint between the lower shell and the connecting seat. The overflow material generated is contained inside the outer overflow groove and the outer residual material groove, improving the product's appearance. The product has no foreign objects on its surface, making it more aesthetically pleasing and increasing its competitiveness. Furthermore, it eliminates the need for subsequent deburring work by workers, improving production efficiency. When workers hold the product, there will be no burrs scratching their hands, ensuring safety and efficiency. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-8As shown, this utility model provides a novel spin-welded retaining structure, including an upper shell 1, a lower shell 2, and a connecting seat 3. The upper shell 1 and the connecting seat 3 are interlocked and fixed together, and the connecting seat 3 is rotatably welded together. The lower shell 2 has an integrally formed connecting ring 201, an inner retaining ring 203, and an outer retaining ring 204 on the side facing the connecting seat 3. The outer retaining ring 204 is disposed outside the connecting ring 201, and the inner retaining ring 203 is disposed inside the connecting ring 201. The connecting seat 3 has an opening on the side facing the lower shell 2. The welding fixture includes a connecting groove 301, an outer residual material groove 303, and an inner residual material groove 304. A connecting ring 201 corresponds to the connecting groove 301, causing the connecting ring 201 to rotate relative to the connecting groove 301 after contact. This causes the outer retaining ring 204 to rub against and fuse with the connecting groove 301. An overflow groove 205 is formed between the outer retaining ring 204 and the connecting ring 201. The outer retaining ring 204 collects the material overflowing from the connecting ring 201 during spin welding and stores the overflow in the overflow groove. Inside 205, an inner overflow groove 202 is formed between the inner retaining ring 203 and the connecting ring 201. Material overflowing inward from the connecting ring 201 is blocked by the inner retaining ring 203 and stored inside the inner overflow groove 202. An outer protrusion 302 is formed between the connecting groove 301 and the outer waste material groove 303. The outer overflow groove 205 corresponds to the outer waste material groove 303. The overflow material is collected through the cavity formed between the outer overflow groove 205 and the outer waste material groove 303, preventing overflow and affecting the product appearance. An outer baffle groove 305 is provided on one side of the connecting seat 3. The outer baffle groove 305 is located outside the outer overflow groove 303. The outer baffle groove 305 is adapted to the outer baffle ring 204. Through the cooperation and closure of the outer baffle ring 204 and the outer baffle groove 305, the overflow material is blocked inside the outer overflow groove 205 inside the outer baffle ring 204, which improves the blocking effect of the overflow material, increases the contact area between the overflow material and the lower shell 2 and the connecting seat 3, and improves the fixing strength of the weld after the molten overflow material cools down inside the outer overflow groove 205.

[0024] An inner overflow groove 202 is formed between the connecting ring 201 and the inner retaining ring 203. The inner overflow groove 202 corresponds to the inner residual material groove 304. The overflow material generated inside the connecting ring 201 is collected through the inner overflow groove 202 and the inner residual material groove 304 to prevent the overflow material from overflowing from the inner side of the lower housing 2 and the connecting seat 3. The overflow material falls into the inner residual material groove 304 and the inner overflow groove 202 and cools down, sealing the gap and improving the airtightness.

[0025] In use, the lower housing 2 and the connecting seat 3 are clamped and fixed by a spin welding fixture. The fixture then drives the lower housing 2 and the connecting seat 3 closer together, aligning the connecting ring 201 with the connecting groove 301. The fixture applies force to rotate and push the connecting ring 201 into the connecting groove 301. The high temperature generated by friction melts the connecting ring 201. Since the connecting groove 301 is smaller than the connecting ring 201, after the contact area between the connecting ring 201 and the connecting groove 301 melts, excess material is squeezed out of the connecting groove 301 and overflows to both the inside and outside of the connecting groove 301, flowing towards the connecting groove. The overflow material inside 301 will fall between the inner overflow trough 202 and the inner residual material trough 304. The overflow material is stored in the cavity between the inner overflow trough 202 and the inner residual material trough 304, and the overflow material is blocked by the inner retaining ring 203 to prevent the overflow material from entering the inner cavity of the lower housing 2. The overflow material falls into the inner residual material trough 304 and the inner overflow trough 202 and cools down, sealing the gap and improving the airtightness. The melted overflow material in the cavity increases the contact area with the lower housing 2 and the connecting seat 3. After medical cooling and solidification, it increases the fixing strength of the lower housing 2 and the connecting seat 3 and increases the service life of the product.

[0026] The overflow material flowing to the outside of the connecting groove 301 falls into the cavity between the outer overflow groove 205 and the outer residual material groove 303. The outer retaining ring 204 and the outer retaining groove 305 simultaneously block the overflow material, preventing the overflow material from flowing out of the joint between the lower housing 2 and the connecting seat 3. The overflow material generated is contained inside the outer overflow groove 205 and the outer residual material groove 303, improving the product's appearance. The product has no foreign objects on its surface, making it more aesthetically pleasing and increasing its competitiveness. Furthermore, it eliminates the need for subsequent deburring work by workers, improving production efficiency. When workers hold the product, there will be no burrs scratching their hands, making it safe and efficient.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
