Description

Technical Field

[0001] The utility model relates to the technical field of swimming pool water pumps, in particular to a split swimming pool water pump and a device for realizing friction welding of various parts of the split swimming pool water pump. Background Art

[0002] The swimming pool pump is an important device in the swimming pool field. Its main function is to promote the circulation and filtration of pool water. The variable frequency swimming pool pump can also work at the optimal speed and flow required for swimming pool applications, minimizing energy consumption. During the use of the swimming pool pump, the pool water flows in from the water inlet, passes through the filter basket in the container, flows through the volute and impeller in the pump body, and finally flows out from the outlet of the pump cover.

[0003] However, the pump body assembly of the traditional swimming pool water pump is a container and a pump body with an impeller and a volute installed, which is molded out of the mold as a whole, resulting in a more complex shape of the pump body assembly, which increases the difficulty of demolding. The demolding of the pump body assembly needs to take into account the filter container, the water inlet section, the decorative patterns on the surface of the pump body, etc., especially the water inlet section and the surface decorative patterns. Most of them are composed of curved surfaces, and there are many places with uneven thickness. If some details are not handled well, there will be obvious shrinkage deformation, which will affect the appearance of the pump body and even the hydraulic performance. In addition, the size of the pump body assembly manufactured by one-piece injection molding is large and not easy to demold; if the size span is too large, the shrinkage and deformation will also increase, especially in some transition places, the outer surface is prone to defects, and the key matching dimensions will also be affected, affecting the performance of the water pump. In addition, the injection molding machine power required for the pump body assembly manufactured by one-piece injection molding is large; the injection molding machine power is large, the pressure is easy to be too high, and the injection time is easy to be set too long, which is a problem that the machine adjuster is not easy to detect. Therefore, the mold is easy to break the needle, the residual internal stress increases, and the brittleness of the water inlet position of the injection molded part is aggravated. Existing water pumps have the above-mentioned problems during injection molding manufacturing, which also restricts the appearance design of the water pump and makes it difficult to freely beautify the appearance of the water pump.

[0004] Therefore, it is urgent to solve the many disadvantages of traditional water pumps caused by one-piece injection molding. Utility Model Content

[0012] When the two water transport circular pipes are friction welded to each other, the annular boss is sleeved in the annular groove, and each of the first annular step surfaces is in contact with each of the second annular step surfaces.

[0013] According to a split-type swimming pool water pump of the utility model, the outer wall of the annular boss is formed with a first annular inclined surface, and the inner wall of the annular groove is formed with a second annular inclined surface;

[0014] Wherein, when the two water transport circular pipes are friction welded to each other, the first annular inclined surface and the second annular inclined surface are in contact with each other.

[0015] The utility model discloses a device for realizing friction welding of various parts of a split swimming pool water pump, comprising a base, on which a translation mechanism and a lifting mechanism are arranged;

[0016] The translation mechanism and the lifting mechanism are respectively provided with a first clamp and a second clamp for fixing two split components of the split water pump;

The complexity of the water pump is reduced and the difficulty of demolding is reduced. Since it is divided into two parts, the two parts can be injection molded separately, so the parts and curved surfaces with uneven thickness are reduced, the complexity is naturally reduced, and it is easier to demold. At the same time, the size of the water pump injection molded part is also significantly reduced, which is convenient for demolding. The small size reduces the shrinkage deformation. The internal flow channel of the water inlet section is smoother and smoother, with less resistance, and the power of the injection molding machine required to manufacture the water pump can be smaller, avoiding the problems of high pressure, increased residual internal stress, and long injection time caused by the high power of the injection molding machine, thereby improving production efficiency, and further reducing the restrictions on the design of the water pump shape, which is convenient for the free beautification of the appearance of the water pump. Therefore, to a certain extent, it can solve the many disadvantages of traditional water pumps caused by integrated injection molding.

[0040] The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be understood as limitations on the utility model. In the description of the utility model, it is necessary to understand that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the accompanying drawings, only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the utility model.

[0041] like Figures 1 to 3 As shown, a split swimming pool water pump of the present embodiment is split into two split components 1 which are integrally formed respectively, wherein one split component 1 is a pump body component of the water pump, and the other split component 1 is a container component of the water pump, the pump body component and the container component are respectively integrally formed with a water transporting circular pipe 2 extending outward, the water transporting circular pipe 2 of the pump body component and the water transporting circular pipe 2 of the container component correspond to each other, and the water transporting circular pipe 2 of the pump body component and the water transporting circular pipe 2 of the container component are coaxially docked with each other and friction welded to each other.

[0042] It can be understood that in this embodiment, the water pump is split into two split components 1, and the two split components 1 are independently injection-molded as one body and then spliced ​​together. At the same time, the two split components 1 are respectively provided with a water transport pipe 2 extending outward. When the two split components 1 are spliced ​​together, the two water transport pipes 2 opposite to each other in the two split components 1 are coaxially spliced ​​and friction-welded with each other, so that the entire split water pump can be effectively spliced ​​into a whole. It should also be noted that circular water transport pipes 2 are respectively provided on the two split components 1. Therefore, when the friction welding process is performed, the two circular water transport pipes 2 can be more easily welded through relative rotation friction, the docking is more accurate, and the sealing of the water pump after friction welding can be ensured. It can be seen that the split water pump structural solution of the utility model can help solve the problems that the water pump component is large in size and requires a large-tonnage injection molding machine, resulting in large deformation, large average thickness, and difficulty in improving deformation. The complexity of the water pump is reduced and the difficulty of demolding is reduced. Since it is divided into two parts, the two parts can be injection molded separately, so the parts and curved surfaces with uneven thickness are reduced, the complexity is naturally reduced, and it is easier to demold. At the same time, the size of the water pump injection molded part is also significantly reduced, which is convenient for demolding. The small size reduces the shrinkage deformation. The internal flow channel of the water inlet section is smoother and smoother, with less resistance, and the power of the injection molding machine required to manufacture the water pump can be smaller, avoiding the problems of high pressure, increased residual internal stress, and long injection time caused by the high power of the injection molding machine, thereby improving production efficiency, and further reducing the restrictions on the design of the water pump shape, which is convenient for the free beautification of the appearance of the water pump. Therefore, to a certain extent, it can solve the many disadvantages of traditional water pumps caused by integrated injection molding.

[0043] In one embodiment, the two water transport circular pipes 2 that are friction welded to each other are respectively integrally formed with an annular male stop 3 and an annular female stop 4. When the two water transport circular pipes 2 are friction welded to each other, the annular male stop 3 is fitted into the annular female stop 4, so that the mutual cooperation between the annular male stop 3 and the annular female stop 4 can be utilized to ensure the stability of the two water transport circular pipes 2 when friction welding to each other.

[0044] In one embodiment, a thickening ring 5 is integrally formed on the outer circumference of the annular female stop 4, and the thickening ring 5 surrounds the water transport circular pipe 2. Therefore, the thickness of the water transport circular pipe 2 at the position corresponding to the annular female stop 4 can be increased to improve the structural strength of the position of the annular female stop 4 and improve the stability of the water transport circular pipe 2 during friction welding.

[0045] In one embodiment, two first annular step surfaces 32 are formed on the annular male stop 3, and the two first annular step surfaces 32 are respectively formed at the outer position and the inner position of the annular boss 31. On the other hand, two second annular step surfaces 42 are formed on the annular female stop 4, and the two second annular step surfaces 42 are respectively formed at the outer position and the inner position of the annular groove 41. When the two water transport circular pipes 2 are friction welded to each other, the annular boss 31 is fitted into the annular groove 41, and each first annular step surface 32 is respectively in contact with each second annular step surface 42. This structure can significantly further improve the stability of the two water transport circular pipes 2 when friction welding to each other, and ensure the smooth progress of friction welding.

[0046] In one embodiment, a first annular bevel 33 is formed on the outer wall of the annular boss 31, and a second annular bevel 43 is formed on the inner wall of the annular groove 41. When the two water transport circular pipes 2 are friction welded with each other, the first annular bevel 33 and the second annular bevel 43 contact each other, thereby increasing the contact area of ​​the annular boss 31 when entering the annular groove 41. By increasing the contact area between the annular boss 31 and the annular groove 41, the stability of the two water transport circular pipes 2 when friction welding with each other is improved.

[0047] In addition, in order to facilitate the splicing of the various parts of the split water pump, the two split components 1 of the split water pump are smoothly spliced ​​into one, such as Figures 4 to 8 Combined with Figures 1 to 3 As shown, this embodiment also provides a device for realizing friction welding of various parts of a split swimming pool water pump, and its structure includes a base 100, a first clamp 200 and a second clamp 300. The first clamp 200 and the second clamp 300 are respectively used to fix the two split components 1 of the split water pump. Specifically, the first clamp 200 is used to fix the container component of the split water pump, and the second clamp 300 is used to fix the pump body component of the split water pump. In addition, a translation mechanism and a lifting mechanism are installed on the base 100. The first clamp 200 is mounted on the translation mechanism, and the second clamp 300 is mounted on the lifting mechanism. At the same time, the lifting mechanism is also equipped with a motor (not marked in the figure) for driving the second clamp 300 to rotate. When working, the translation mechanism is used to drive the first clamp 200 to translate to the bottom of the second clamp 300, and the lifting mechanism is used to drive the second clamp 300 to move up and down above the first clamp 200. In addition, the welding device is also provided with a control system, which can control the movement of the translation mechanism, the lifting mechanism and the motor respectively. The control system part includes a plurality of buttons 400. Operating each button 400 can send different control signals to the control system respectively. Since the control system for controlling the movement of the translation mechanism, the lifting mechanism and the motor belongs to the prior art, it will not be described in detail here.

[0048] Through the above structure, in actual work, the container component of the split water pump is first clamped on the first clamp 200, and the pump body component of the split water pump is also clamped on the second clamp 300. After the various parts of the split water pump are fixed, the corresponding button 400 is operated to control the movement of the translation mechanism to drive the first clamp 200 to move horizontally to the bottom of the second clamp 300, so that the water transport pipe 2 of the pump body component and the water transport pipe 2 of the container component correspond to each other up and down. At this time, the corresponding button 400 is operated to control the movement of the lifting mechanism to drive the second clamp 300 to descend, so that the pump body component of the split water pump moves straight downward to the preset welding start position, and the water transport pipe 2 of the pump body component and the water transport pipe 2 of the container component are also in a state of docking with each other, and then the motor is started to rotate to make the second clamp 300 rotate at high speed, which is equivalent to using the motor to drive one of the transport pipes The water pipe 2 rotates, and the lifting mechanism continues to drive the second clamp 300 to descend and move downward to the preset welding completion position. The two water pipes 2 generate relative rotation friction. During this rotation friction process, the two water pipes 2 melt into one due to the high temperature generated by the high-speed rotation friction, so that the pump body component of the split water pump and the container component of the split water pump can be spliced ​​together. Then, the lifting mechanism can be controlled to drive the second clamp 300 to rise to the initial position. At this time, since the pump body component and the container component of the split water pump have been connected as one, the overall weight increases, so the second clamp 300 cannot continue to stably clamp the pump body component. The second clamp 300 can smoothly separate from the pump body component when it rises. Finally, the translation mechanism is controlled to drive the first clamp 200 back to the initial position, and the spliced ​​water pump component can be taken out from the first clamp 200. It can be seen from this that the friction welding device of the utility model can help to realize the splicing of various parts of the split water pump, so that the split water pump can be smoothly spliced ​​into one.

[0049] In one embodiment, specifically, the translation mechanism includes a transverse guide rail 201, and at least one slider 202 is slidably arranged on the transverse guide rail 201. In this embodiment, the number of transverse guide rails 201 and sliders 202 is two, and both ends of each slider 202 are slidably installed on different transverse guide rails 201, and the first clamp 200 is fixedly arranged on each slider 202, so that the translation of the first clamp 200 can be realized, and the translation process is also relatively stable.

[0050] In one embodiment, specifically, a first profiling groove 203 is formed on the first fixture 200, and the first profiling groove 203 is used to match the outer surface of the split component 1 of the water pump, and a plurality of profiling circular holes 204 are formed in the first profiling groove 203, and the profiling circular holes 204 are used to match the water transporting circular pipe 2 and other tubular structures of the split component of the water pump. That is, when the container component of the split water pump is placed in the first fixture 200, the first profiling groove 203 can match the outer surface of the container component, and the profiling circular holes 204 can also match and fix the container component, so that the container component of the split water pump can be more stably installed in the first fixture 200.

[0051] In one embodiment, specifically, a vertically extending vertical pole (not shown in the figure) is fixed on the base 100, a mounting seat 302 is fixed on the top of the vertical pole, a lifting mechanism is assembled in the mounting seat 302, a motor for driving the second fixture 300 to rotate is also assembled in the mounting seat 302, a vertically arranged transmission rod 301 is fixedly sleeved at the rotation center of the second fixture 200, and the transmission rod 301 is coaxially connected to the rotation shaft of the motor, so the motor can drive the second fixture 200 to rotate while driving the transmission rod 301 to rotate; and the lifting mechanism in the mounting seat 302 is transmitted to the transmission rod 301 to drive the transmission rod 301 to rise and fall, so the lifting mechanism can drive the second fixture 200 to rise and fall while driving the transmission rod 301 to rise and fall. Optionally, in the mounting seat 302, the lifting mechanism can be connected to the housing of the motor, and when the lifting mechanism drives the motor to rise and fall, the transmission rod 301 and the second fixture 200 can be synchronously driven to rise and fall.

[0052] In one embodiment, specifically, a second profiling groove 303 is formed on the second fixture 300, and the second profiling groove 303 is used to match the outer surface of the split component 1 of the water pump. A plurality of clamping grooves 304 are formed on the second profiling groove 303, and the clamping grooves 304 surround the outer periphery of the second profiling groove 303, and the clamping grooves 304 are used to clamp the outer surface structure of the split component 1 of the water pump. In addition, an arc groove 305 is also formed on the second fixture 300, and the arc groove 305 is used to match the water transport pipe 2 of the split component 1. That is, when the pump body component of the split water pump is placed in the second fixture 300, the second profiling groove 303 can match the outer surface of the pump body component, the arc groove 305 can match the water transport pipe 2 of the pump body component, and each clamping groove 304 also clamps the external structure of the pump body component, and the above structure can make the pump body component of the split water pump more stably installed in the second fixture 300. The snap-in groove 304 is a semicircular groove, which can increase the contact area between the snap-in groove 304 and the outer surface structure of the split component 1 of the water pump, thereby improving the friction between the two. When the outer surface structure of the split component 1 of the water pump is snap-fitted to the snap-in groove 304, the installation stability of the two can be further increased.

[0053] In one embodiment, the transverse guide rail 201 is optionally an I-shaped guide rail, and arc-shaped guide rail grooves 205 are formed in the middle of the left and right sides of the I-shaped guide rail, respectively. The slider 202 is also formed with protrusions that slide and fit in the arc-shaped guide rail grooves 205, respectively. This structure can not only ensure the normal sliding of the slider 202, but also prevent the slider 202 from easily falling off the transverse guide rail 201, and the structure is more stable and reliable. The arc-shaped guide rail groove 205 is a semicircular groove, which can increase the contact area between the protrusion on the slider 202 and the arc-shaped guide rail groove 205, ensure smoother sliding, better wrap the protrusion on the slider 202, and further prevent the slider 202 from falling off the transverse guide rail 201; the front and rear ends of the transverse guide rail 201 are provided with a limiting structure to prevent the slider 202 from sliding excessively, so as to ensure the precise positioning of the two split components 1 during friction welding.
