Description

Technical Field

[0001] This invention belongs to the technical field of pump assembly equipment and relates to an assembly device for thrust washers. Background Technology

[0002] A canned motor pump is a leak-free pump that integrates a canned motor and a pump. Its stator and rotor are isolated by non-magnetic, corrosion-resistant thin-walled sleeves, and the rotor is supported by front and rear bearings and immersed in the conveying medium. Therefore, no dynamic seals of any kind are required to prevent the conveyed medium from leaking outward.

[0003] The structure of a canned motor pump, as disclosed in patent literature (application number: 201220289003.8), includes a housing, stator, rotor, shielding sleeve, shaft, impeller, and shaft seat. The shielding sleeve isolates the pump chamber and the motor chamber. The shaft seat is installed inside the motor chamber. One end of the shaft is movably mounted on the shaft seat, and the other end of the shaft is equipped with an impeller. The housing has an inlet and an outlet, both of which are connected to the pump chamber. Thrust washers are typically fitted onto the rotor shaft of the canned motor pump to position the rotor. Currently, the assembly of thrust washers on the rotor is done manually. This assembly method is not only wasteful of manpower and inefficient, but also difficult to guarantee in terms of assembly quality due to the varying skill levels of the workers. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an assembly device for thrust washers. The technical problem solved by this invention is: how to improve the assembly efficiency of thrust washers and rotors while simultaneously achieving good lubrication of the rotor shaft.

[0005] The objective of this invention can be achieved through the following technical solution: an assembly device for a thrust washer, comprising a support and a rotor positioning seat disposed on the support, characterized in that the support is provided with a robotic arm located above the rotor positioning seat for clamping the thrust washer, the robotic arm being able to move up and down relative to the rotor positioning seat, the rotor positioning seat comprising a main body, the main body having a horizontally arranged support plane for placing the rotor, the main body also having an arc-shaped limiting part protruding upward relative to the support plane, the support also having an oil spraying component one capable of spraying oil toward the rotor when the rotor is placed on the support plane, the support plane having a vertically arranged oil spraying hole, and the rotor positioning seat also having an oil spraying component two capable of spraying oil into the oil spraying hole.

[0006] This assembly device is mainly used to assemble the thrust washer and rotor of a canned motor pump. The rotor of the canned motor pump includes a rotor body and a shaft. The first oil spray component is usually an oil nozzle. In the specific assembly process, firstly, the rotor is placed on the support plane by a robotic arm. At this time, the lower end of the shaft extends into the oil spray hole, and the lower end face of the rotor body abuts against the support plane. Then, the first oil spray component sprays oil onto the shaft of the rotor for the first time. After that, the robotic arm holds the thrust washer and moves it downward to put the thrust washer onto the shaft of the rotor, completing the installation of the thrust washer. After installation, the robotic arm moves upward to reset. Then, the first oil spray component sprays oil for the second time, while the second oil spray component can spray oil into the oil spray hole to lubricate the shaft.

[0007] Of course, in the above steps, the number of times the first and second oil sprayers are sprayed, as well as when the second oil sprayer is sprayed, can be flexibly adjusted.

[0008] In the canned motor pump involved in this case, the thrust washer comprises a rubber ring made of rubber material and a thrust plate embedded within the rubber ring. The inner circle of the rubber ring encloses the rotor shaft, and the rubber ring also supports the thrust plate. The pump casing of the canned motor pump has bushings at both ends corresponding to the rotor shaft. These bushings support the ends of the shaft, thus enabling rotor installation. The thrust washer restricts radial movement of the shaft when it mates with the bushing. During assembly, the shaft needs to be sprayed with oil to lubricate the shaft and bushing, preventing wear on the bushing.

[0009] While assembling the thrust washer and rotor manually is time-consuming and labor-intensive, the manual assembly process allows for easy rotation of the rotor for lubrication, thus ensuring effective lubrication. However, with the automated assembly in this device, ensuring proper lubrication of the shaft becomes more challenging. To address this, the assembly device incorporates vertical oil spray holes on the main body, along with a second oil sprayer capable of spraying oil into these holes. During the process of the robotic arm clamping the rotor onto the rotor positioning seat, when the lower end of the shaft moves to the upper opening of the oil spray hole but before the shaft fully penetrates it, a ring-shaped gap forms between the lower end of the shaft and the edge of the upper opening. At this point, the second oil sprayer can also spray oil into the hole. The oil atomizes as it passes through the gap, resulting in a smooth surface between the lower end of the rotor body and the support plate. Oil mist forms between the surfaces, but due to the presence of the limiting part, it effectively blocks the oil mist, preventing it from easily escaping outside the rotor positioning seat. Instead, it effectively lubricates the lower end face of the rotor, improving the lubrication effect. Furthermore, after this process, some oil adheres to the limiting part, flowing downwards to the supporting plane, maintaining a layer of oil on the supporting plane. This ensures good lubrication when the rotor body's end face contacts the supporting plane, further enhancing lubrication. Once the rotor is placed on the supporting plane, the limiting part further restricts its movement, and the lower end of the shaft extends into the oil injection hole, thus limiting the shaft as well. This design allows the rotor to be stably and accurately positioned on the supporting plane, ensuring the assembly accuracy and quality of the rotor and thrust washer.

[0010] Therefore, in this assembly device, the limiting part on the main body plays three roles: limiting, blocking oil mist, and allowing the oil to flow downward to the support plane. Through this design, the rotor and thrust washer can achieve automated assembly and improve assembly efficiency, while also ensuring assembly accuracy and greatly improving the lubrication effect on the rotor, so that the finally assembled canned pump has good working stability.

[0011] In the aforementioned thrust washer assembly device, an oil passage hole is also provided on the lower end face of the rotor positioning seat. The second oil injector is connected to the lower end of the oil passage hole, and the upper end of the oil passage hole communicates with the oil injection hole. The oil injection hole and the oil passage hole are concentrically arranged, and the diameter of the oil injection hole is larger than the diameter of the oil passage hole. The second oil injector is usually an oil injection connector. In order to enable the oil injection connector to spray oil, an oil pump is usually installed in the oil receiving groove. The oil injection connector is connected to the oil pump through a hose. The diameter of the oil injection hole is slightly larger than the diameter of the rotor shaft. This way, when the rotor is placed on the support plane, a small gap is formed between the inner wall of the oil injection hole and the outer wall of the shaft, allowing the oil to enter the gap and effectively lubricate the shaft. The smaller diameter of the oil passage hole serves two purposes: first, it can increase the oil injection pressure, improve the oil injection effect and the lubrication effect on the rotor; second, the smaller diameter of the oil passage hole facilitates connection with the oil injection connector.

[0012] In the aforementioned thrust washer assembly device, the upper sidewall of the oil injection hole is connected to the supporting plane via an annular chamfered bevel. As mentioned above, during the process of the robotic arm clamping the rotor and placing it onto the rotor positioning seat, when the lower end of the rotating shaft moves to the upper opening of the oil injection hole but before the rotating shaft extends into the oil injection hole, an annular gap is formed between the lower end of the rotating shaft and the edge of the upper opening of the oil injection hole. At this time, when the oil injection component sprays oil into the oil injection hole, the oil will produce an atomization effect when passing through the gap. The chamfered bevel design helps the oil mist to spread evenly when sprayed upwards, thereby making the lubrication of the rotor more uniform and improving the lubrication effect of the rotor.

[0013] In the aforementioned thrust washer assembly device, the top surface of the main body has a protrusion and a recessed relief platform relative to the protrusion. The top surface of the protrusion is the supporting plane. A placement notch is formed between the two ends of the limiting part, and positioning grooves are formed between the two ends of the limiting part and the protrusion, respectively. The bottom surface of the positioning groove is coplanar with the relief platform. The rotor is clamped onto the rotor positioning seat by a robotic arm, which has a protrusion supporting the lower end face of the rotor body. By setting the recessed relief platform relative to the protrusion, the protrusion on the robotic arm can be embedded in the relief platform, and the positioning groove can also be used for insertion and positioning by the robotic arm, so that the robotic arm can stably and accurately place the rotor on the supporting plane.

[0014] In the aforementioned thrust washer assembly device, the main body is cylindrical, with its outer side wall coplanar with the outer side wall of the limiting part, and the side wall of the protrusion facing the placement notch is arc-shaped. This design facilitates the manufacturing of the rotor positioning seat. Furthermore, since the side wall of the protrusion facing the placement notch is arc-shaped, and the robotic arm also has a surface that mates with this arc-shaped surface, the positioning accuracy of the robotic arm is improved, enabling it to stably and accurately place the rotor on the support plane.

[0015] In the aforementioned thrust washer assembly device, the support includes a support column and a support platform fixed to the upper end of the support column. The support platform is equipped with a mounting frame, and the mounting frame has a lifting cylinder with a downwardly extending piston rod. A connecting block is connected to the lower end of the piston rod of the lifting cylinder, and the robotic arm is connected to the connecting block. The mounting frame has a box-shaped structure, and the lifting cylinder is located inside the mounting frame, making the equipment more aesthetically pleasing and safer. The extension and retraction of the piston rod of the lifting cylinder can drive the connecting block and the robotic arm to move up and down.

[0016] In the aforementioned thrust washer assembly device, the support is further equipped with a feeding cylinder and a conveying track located on one side of the mounting frame for conveying the thrust washers. The piston rod of the feeding cylinder is horizontally positioned and connected to a feeding plate. The feeding plate is connected to the outlet end of the conveying track. The feeding cylinder can also move the feeding plate to directly below the robotic arm. The conveying track continuously conveys the thrust washers forward. When the feeding plate is empty, the conveying track can convey the thrust washers onto the feeding plate. Then, the piston rod of the feeding cylinder extends, moving the feeding plate directly below the robotic arm, which can then grab the thrust washers from the feeding plate. After the grabbing operation is completed, the feeding cylinder drives the feeding plate to retract and reset. At this time, the conveying track replenishes the thrust washers onto the feeding plate again. This cycle repeats, achieving automatic feeding of thrust washers, thereby improving the automation level and assembly efficiency of the equipment.

[0017] In the aforementioned thrust washer assembly device, an oil receiving groove is also connected to the support platform below the rotor positioning seat. Excess oil on the rotor positioning seat will flow out from the placement notch and fall into the oil receiving groove, avoiding oil waste. At the same time, the oil receiving groove stores oil, which can then be continuously supplied to the first and second oil injection components by the oil pump.

[0018] In the aforementioned thrust washer assembly device, both the robotic arm and the rotor positioning seat are located on the front side of the mounting frame. Two oil sprayers are provided, each positioned on the front side of the mounting frame. These two oil sprayers can spray oil onto the rotor from two directions, ensuring uniform lubrication and improving the lubrication effect. The robotic arm and rotor positioning seat being located on the front side of the mounting frame facilitate the robotic arm's placement of the rotor onto the rotor positioning seat.

[0019] In the aforementioned thrust washer assembly device, the robotic arm includes a drive unit and two symmetrical arc-shaped clamping plates connected to the drive unit. The concave surfaces of the two arc-shaped clamping plates face each other, and both are vertically oriented. The drive unit can move the two arc-shaped clamping plates closer together or further apart. When the drive unit moves the two arc-shaped clamping plates closer together, the robotic arm clamps the thrust washer. Then, by moving the robotic arm downwards, the thrust washer can be installed onto the rotor shaft. After installation, the drive unit moves the two arc-shaped clamping plates further apart, releasing the thrust washer. Using two arc-shaped clamping plates to hold the thrust washer improves clamping stability.

[0020] Compared with existing technologies, the assembly device for this thrust washer has the following advantages:

[0021] 1. In this assembly device, the limiting part on the main body plays three roles: limiting, blocking oil mist, and allowing the oil to flow downward to the support plane. Through this design, the rotor and thrust washer can achieve automated assembly and improve assembly efficiency, while also ensuring assembly accuracy and greatly improving the lubrication effect on the rotor, so that the finally assembled canned pump has good working stability.

[0022] 2. This assembly device can automatically feed thrust washers, thereby improving the automation level and assembly efficiency of the equipment. Attached Figure Description

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] like Figure 1 and Figure 2 As shown, the assembly device for this thrust washer includes a support 1 and a rotor positioning seat 2 mounted on the support 1. The support 1 includes a support column 1a and a support platform 1b fixed to the upper end of the support column 1a. The support platform 1b is provided with a mounting bracket 1c. The mounting bracket 1c is provided with a robotic arm 4 located above the rotor positioning seat 2 for clamping the thrust washer 3. The robotic arm 4 can move up and down relative to the rotor positioning seat 2. The rotor positioning seat 2 includes a main body 21. The main body 21 has a horizontally arranged support plane 211 for placing the rotor 15. The main body 21 is also provided with an arc-shaped limiting part 22 that protrudes upward relative to the support plane 211. The support 1 is also provided with an oil spraying component 5 that can spray oil toward the rotor 15 when the rotor 15 is placed on the support plane 211. The support plane 211 has a vertically arranged oil spraying hole 212. The rotor positioning seat 2 is connected to an oil spraying component 6 that can spray oil into the oil spraying hole 212. The oil spraying component 6 is an oil spraying connector.

[0035] like Figure 1 As shown, the support 1 is also equipped with a feeding cylinder 9 and a conveying track 10 located on one side of the mounting frame 1c for conveying the thrust washer 3. The piston rod of the feeding cylinder 9 is horizontally arranged and a feeding plate 11 is connected to the piston rod. The feeding plate 11 is connected to the outlet end of the conveying track 10. The feeding cylinder 9 can also drive the feeding plate 11 to move directly below the robot arm 4.

[0036] like Figures 2 to 4As shown, an oil passage hole 213 is also provided on the lower end face of the rotor positioning seat 2. The oil injection component 6 is connected to the lower end of the oil passage hole 213. The upper end of the oil passage hole 213 is connected to the oil injection hole 212. The oil injection hole 212 and the oil passage hole 213 are concentrically arranged, and the diameter of the oil injection hole 212 is larger than the diameter of the oil passage hole 213. The side wall of the upper end of the oil injection hole 212 is connected to the support plane 211 through an annular chamfered slope 214.

[0037] like Figure 1 As shown, the support platform 1b is also connected to an oil receiving groove 12 located below the rotor positioning seat 2. Both the robotic arm 4 and the rotor positioning seat 2 are located on the front side of the mounting frame 1c. The first oil spray element 5 is typically an oil nozzle, and there are two first oil spray elements 5, both of which are located on the front side of the mounting frame 1c. Excess oil on the rotor positioning seat 2 flows out from the placement notch 23 and falls into the oil receiving groove 12, avoiding oil waste. Simultaneously, the oil receiving groove 12 stores oil, which can then be continuously supplied to the first oil spray element 5 and the second oil spray element 6 via an oil pump.

[0038] like Figure 2 As shown, the main body 21 is cylindrical, and the outer wall of the main body 21 is coplanar with the outer wall of the limiting part 22. The top surface of the main body 21 has a protrusion 215 and a recessed relief platform 216 opposite to the protrusion 215. The top surface of the protrusion 215 is a supporting plane 211. A placement notch 23 is formed between the two ends of the limiting part 22. Positioning grooves 24 are formed between the two ends of the limiting part 22 and the protrusion 215, respectively. The bottom surface of the positioning grooves 24 is coplanar with the relief platform 216. The side wall of the protrusion 215 facing the placement notch 23 is an arc surface. Figure 9 As shown, the rotor 15 is clamped onto the rotor positioning seat 2 by the robotic arm 13. The robotic arm 13 has a protrusion 131 that supports the lower end face of the rotor body 151. When the robotic arm 13 places the rotor 15 on the rotor positioning seat 2, the protrusion 131 can be embedded in the clearance platform 216. The two ends of the protrusion 131 are inserted and positioned in two positioning grooves 24. At the same time, the robotic arm 13 also has an arc-shaped surface that fits and abuts against the arc surface. Therefore, the robotic arm 13 can stably and accurately place the rotor 15 on the support plane 211, improving the assembly accuracy.

[0039] like Figure 6As shown, the robotic arm 4 includes a drive unit 41 and two symmetrical arc-shaped clamping plates 42 connected to the drive unit 41. The concave surfaces of the two arc-shaped clamping plates 42 face each other, and both arc-shaped clamping plates 42 are vertically arranged. The drive unit 41 can drive the two arc-shaped clamping plates 42 to move closer together or further apart. When the drive unit 41 drives the two arc-shaped clamping plates 42 to move closer together, the robotic arm 4 can clamp the thrust washer 3. At this time, by moving the robotic arm 4 downward, the thrust washer 3 can be installed onto the rotating shaft 152 of the rotor 15. After installation, the drive unit 41 then drives the two arc-shaped clamping plates 42 to move further apart, thus releasing the thrust washer 3. Using two arc-shaped clamping plates 42 to clamp the thrust washer 3 can improve the stability of the clamping.

[0040] like Figure 6 and Figure 7 As shown, the mounting frame 1c has a box-shaped structure. Inside the mounting frame 1c is a lifting cylinder 7 with a piston rod extending downwards. The lower end of the piston rod of the lifting cylinder 7 is connected to a connecting block 8, and the robotic arm 4 is connected to the connecting block 8. The lifting cylinder 7 is located inside the mounting frame 1c, making the equipment more aesthetically pleasing and safer. By extending and retracting the piston rod of the lifting cylinder 7, the connecting block 8 and the robotic arm 4 can be moved up and down.

[0041] This assembly device is mainly used to assemble the thrust washer 3 and rotor 15 of the canned motor pump, such as... Figure 8 As shown, the rotor 15 of the canned motor pump includes a rotor body 151 and a shaft 152. The thrust washer 3 includes a rubber ring 31 made of rubber material and a thrust plate 32 embedded in the rubber ring. The inner circle of the rubber ring 31 surrounds the rotor shaft 152, and the rubber ring 31 can support the thrust plate 32. The working principle of this device is briefly described below:

[0042] like Figure 1 As shown, firstly, the conveying track 10 continuously conveys the thrust washer 3 forward, so that when the feeding plate 11 is in an empty state, the conveying track 10 can convey the thrust washer 3 onto the feeding plate 11. Then, the piston rod of the feeding cylinder 9 extends, causing the feeding plate 11 to move directly below the robot arm 4. The robot arm 4 moves downward and grabs the thrust washer 3 on the feeding plate 11. After the grabbing work is completed, the feeding cylinder 9 drives the feeding plate 11 to retract and reset. At this time, the conveying track 10 replenishes the thrust washer 3 into the feeding plate 11 again. This cycle is repeated to realize the automatic feeding of the thrust washer 3.

[0043] After that, as Figure 6As shown, the robotic arm 13 places the rotor 15 into the rotor positioning seat 2, and the first oil sprayer 5 sprays oil towards the rotating shaft 152 of the rotor 15 for the first time; then, the robotic arm 4 clamps the thrust washer 3 and moves it downward to put the thrust washer 3 onto the rotating shaft 152 of the rotor 15, and drives the thrust washer 3 to rotate several times to complete the installation of the thrust washer 3. During this process, the robotic arm 13 always clamps the rotor 15. After the thrust washer 3 is installed, the robotic arm 4 moves upward to reset; then, the first oil sprayer 5 sprays oil for the second time, and at the same time, the second oil sprayer 6 can spray oil into the oil spray hole 212 to lubricate the rotating shaft 152.

[0044] Of course, in the above steps, the number of times oil is sprayed by oil spray component 5 and oil spray component 6, as well as when oil spray component 6 sprays oil, can be flexibly adjusted.

[0045] In this assembly device, by providing a vertical oil injection hole 212 on the main body 21, and simultaneously providing an oil spraying component 6 capable of spraying oil into the oil injection hole 212, during the process of the robotic arm 13 clamping the rotor 15 and placing it onto the rotor positioning seat 2, when the lower end of the rotating shaft 152 moves to the upper opening of the oil injection hole 212 but before the rotating shaft 152 extends into the oil injection hole 212, an annular gap 14 will be formed between the lower end of the rotating shaft 152 and the edge of the upper opening of the oil injection hole 212. Figure 5 As shown, at this time, the second oil sprayer 6 can also spray oil into the oil spray hole 212. When the oil passes through the gap 14, it will produce an atomization effect and form an oil mist between the lower end of the rotor body 151 and the support plane 211. The design of the chamfered slope 214 at the upper end of the oil spray hole 212 helps the oil mist to spread evenly when it is sprayed upward, thereby making the lubrication of the rotor 15 more uniform and improving the lubrication effect of the rotor 15. Meanwhile, due to the presence of the limiting part 22, the limiting part 22 can form a blocking effect on oil mist, making it difficult for oil mist to escape from the outside of the rotor positioning seat 2, but instead providing good lubrication to the lower end face of the rotor 15, improving the lubrication effect of the rotor 15; and after this process, some oil will adhere to the limiting part 22, and this oil will flow down the limiting part 22 to the support plane 211, so that the support plane 211 is always covered with a layer of oil, so that the end face of the rotor body 151 can be well lubricated when it comes into contact with the support plane 211, thereby improving the lubrication effect of the rotor 15.
