Description

Technical Field

[0001] This utility model relates to the field of water pump rotor assembly, specifically a water pump rotor assembly fixture. Background Technology

[0002] As the core component of a water pump, the assembly quality of the pump rotor directly affects the pump's performance, efficiency, and lifespan. A typical rotor assembly includes a shaft, an impeller, and bearings located at both ends of the shaft. When assembling a water pump rotor, two sets of bearings need to be assembled at both ends of the rotor.

[0003] In the existing technology, the bearing assembly of water pump rotors is mostly carried out manually or with simple hydraulic equipment. Operators need to press the bearings at both ends of the rotor separately, which is labor-intensive, inefficient, and can easily lead to bearing tilting, resulting in abnormal noise, premature wear, or even damage to the rotor shaft. In addition, existing assembly fixtures lack effective safety protection measures, and there are certain safety hazards in the pressing process.

[0004] Therefore, a water pump rotor assembly fixture is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a water pump rotor assembly fixture to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A water pump rotor assembly fixture includes a base. A control box is fixedly connected to one side of the upper end of the base, and an assembly assembly is provided on the other side. The assembly assembly includes two sets of press-fitting components, which are symmetrical to each other. One set of press-fitting components is slidably installed on the upper end of the base, and the other set of press-fitting components is fixedly connected to the upper end of the base. A mounting seat for installing bearings is fixedly connected to the middle of each set of press-fitting components. A positioning component for installing the rotor is slidably installed on the upper end of the base, and the positioning component is located between the two sets of press-fitting components.

[0008] Preferably, the pressing assembly includes an assembly base, wherein the assembly base of one pressing assembly is slidably mounted on the upper end of the machine base, and the assembly base of the other pressing assembly is fixedly connected to the upper end of the machine base. The two sets of mounting bases are respectively fixedly connected to the two sets of assembly bases. A pressing cylinder is fixedly connected to one side of each of the two sets of assembly bases, and a pressure plate is fixedly connected to the output end of each pressing cylinder. The pressure plate is used to press the bearing in the mounting base.

[0009] Preferably, the upper end of the machine base is horizontally fixed with a guide rail and a guide rod. One set of mounting seats is slidably installed with the guide rod at the upper end and with the guide rail at the lower end. A connecting rod is fixedly connected to one side of the positioning component. One set of mounting seats slidably installed on the machine base is slidably installed with the connecting rod. A cap is fixedly connected to the end of the connecting rod to prevent the mounting seat from detaching from the connecting rod.

[0010] Preferably, both sets of mounting bases are fixedly connected to a bracket and a base at their upper ends. A rod is inserted vertically downward from the top of the bracket. The rod is coaxial with the base. A bearing is sleeved on the side wall of the rod. The bearing at the lowest end is located inside the base.

[0011] Preferably, the positioning component includes a positioning seat, which is slidably mounted on a guide rail. A positioning groove is provided at the upper end of the positioning seat. A positioning cylinder is fixedly connected to one side of the positioning seat. A positioning plate is fixedly connected to the output end of the positioning cylinder.

[0014] 1. This utility model, by setting two sets of symmetrical pressing components and cooperating with sliding positioning components, can complete the pressing operation of the bearings at both ends of the rotor in one go, avoiding the problems of low efficiency and inaccurate assembly caused by multiple flipping and step-by-step pressing in the traditional process, and ensuring the concentricity of the bearing installation.

[0015] 2.

Detailed Implementation

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] A water pump rotor assembly fixture, such as Figures 1-4 As shown, the device includes a base 1, with a control box 2 fixedly attached to one side of the upper end of the base 1. The control box 2 integrates a programmable logic controller (PLC), relays, switches, servo electric cylinders, and other electrical control components. The connection and control between these components are existing technologies. The servo electric cylinder (model HES60-200-10P) is horizontally mounted on the base 1, with its cylinder body fixed to the base 1. Its output push rod is connected to one set of slidable mounting seats 6. The servo electric cylinder receives commands from the PLC and can perform precise displacement and thrust control. The two sets of pressing assemblies are symmetrical; one set of pressing assemblies is slidably mounted on the upper end of the base 1, while the other set is fixedly attached to the upper end of the base 1. Therefore… The two press-fitting components are installed in different ways. Each set of press-fitting components has a mounting seat 7 for installing bearings 19 fixed in the middle. A positioning component for installing rotor 14 is slidably installed on the upper end of the base 1. The positioning component is located between the two sets of press-fitting components. The rotor 14 is horizontally installed in the positioning component. Bearings 19 are installed in both sets of mounting seats 7. The axes of the two sets of bearings 19 and rotor 14 are on the same straight line. Therefore, the press-fitting components concentrically assemble the bearings 19 at both ends of rotor 14. This assembly fixture can complete the pressing operation of bearings 19 at both ends of rotor 14 in one go, avoiding the inefficiency and inaccuracy caused by multiple flipping and step-by-step pressing in the traditional process, and ensuring the concentricity of bearing 19 installation.

[0025] The press assembly includes an assembly base 6. One set of the press assembly assembly's assembly base 6 is slidably mounted on the upper end of the machine base 1, and the other set of the press assembly assembly's assembly base 6 is fixedly connected to the upper end of the machine base 1. Two sets of mounting seats 7 are respectively fixedly connected to the two sets of assembly base 6. A pressing cylinder 8 (model MGGL32-100Z) is fixedly connected to one side of each set of assembly base 6. A pressure plate 9 is fixedly connected to the output end of each pressing cylinder 8. The pressure plate 9 is used to press the bearing 19 inside the mounting seat 7. The bearing 19 is mounted on the mounting seat 7. The pressing cylinder 8 drives the pressure plate 9 to descend, squeezing the bearing 19 to prevent the bearing 19 from falling off the mounting seat 7 and to prevent problems with the assembly angle or accuracy of the bearing 19.

[0026] A guide rail 21 and a guide rod 5 are horizontally fixed to the upper end of the base 1. One set of mounting seats 6 is slidably installed with the upper end of the guide rod 5 and the lower end of the guide rail 21. A connecting rod 15 is fixed to one side of the positioning component. One set of mounting seats 6 slidably installed on the base 1 is slidably installed with the connecting rod 15. A cap is fixed to the end of the connecting rod 15 to prevent the mounting seat 6 from detaching from the connecting rod 15.

[0027] The guide rail 21 and the guide rod 5 enable the assembly seat 6 to slide smoothly and linearly. One end of the connecting rod 15 is fixed to the positioning component, and the other end is fixed to the end cap. One set of assembly seats 6 is located between the positioning component and the end cap. The distance between the assembly seat 6 and the positioning component is limited. After a certain period of time, the assembly seat 6 will push the end cap, and the connecting rod 15 will pull the positioning component, causing the positioning component to disengage from the other set of assembly seats 6.

[0028] Both sets of mounting bases 6 are fixedly connected to the upper end of the bracket 16 and the base 18. The top of the bracket 16 is vertically inserted with the insertion rod 17. The insertion rod 17 is coaxial with the base 18. The side wall of the insertion rod 17 is fitted with a bearing 19. The lowest bearing 19 is located inside the base 18.

[0029] The bearings 19 are inserted into the insert rod 17 in a linear arrangement. The distance between the bottom of the insert rod 17 and the base 18 is greater than the thickness of one bearing 19 but less than the thickness of two bearings 19. This allows the bottom bearing 19 to be pulled out from one side of the base 18 without being restricted by the insert rod 17, making it easy to store and remove the bearing 19.

[0030] The positioning assembly includes a positioning seat 10, which is slidably mounted on a guide rail 21. A positioning groove 11 is provided on the upper end of the positioning seat 10. A positioning cylinder 12 (model CJ2B16-30S) is fixedly connected to one side of the positioning seat 10. A positioning plate 13 is fixedly connected to the output end of the positioning cylinder 12. The positioning plate 13 is located above the positioning groove 11. A V-shaped positioning groove 11 matching the shape of the water pump rotor 14 is provided on the upper surface of the positioning seat 10. When the positioning cylinder 12 is activated, the positioning plate 13 can descend and press and fix the rotor 14 placed in the V-shaped groove.

[0031] A storage box 22 is fixedly attached to one side of the control box 2 for storing the rotor 14, making it easy to retrieve the rotor 14. A fence 3 is provided on the upper end of the base 1. Safety light curtains 4 are fixedly attached to both the fence 3 and one side of the control box 2. The two sets of safety light curtains 4 work together so that when the operator's hand or other body parts accidentally enter the dangerous working area, the safety light curtains 4 can immediately send a signal to stop the equipment operation (the safety light curtains 4 are connected and cooperate with the components in the controller, which is existing technology), effectively avoiding personal injury that may be caused by pressing action.

[0032] The working principle of the water pump rotor 14 assembly fixture provided by this utility model is as follows:

[0033] The operator places the water pump rotor 14 into the V-shaped positioning groove 11 of the positioning seat 10, and then starts the positioning cylinder 12 to drive the positioning plate 13 to move down and press and fix the rotor 14. The two bearings 19 are respectively placed into the mounting seats 7 of the two sets of pressing components. The operator starts the automatic assembly program through the control box 2. The programmable logic controller in the control box 2 sends a command to the servo electric cylinder. The output push rod of the servo electric cylinder begins to extend, pushing the set of sliding mounting seats 6 connected to it to move along the guide rail 21 towards the fixed mounting seat 6. The sliding mounting seat 6 moves first, so that the bearings 19 on its mounting seat 7 contact and abut against the corresponding end shaft of the rotor 14. As the servo electric cylinder continues to push, the entire rotor 14 together with the positioning components is pushed towards the fixed mounting seat 6 until the other end shaft of the rotor 14 also contacts the bearings 19 on the fixed mounting seat 6. The mounting seats 6 are continuously pushed so that the two sets of mounting seats 6 assemble the bearings 19 at both ends of the rotor 14.

[0034] After assembly, the servo electric cylinder receives a reverse command and begins to retract, pulling the connected mounting base 6 back. Since the mounting base 6 is slidably connected to the positioning component through a connecting rod 15, and the end of the connecting rod 15 is provided with a cap, when the mounting base 6 retracts to a certain distance, the cap at the end of the connecting rod 15 will abut against the mounting base 6. Continuing to retract will pull the entire positioning component backward together through the connecting rod 15, so that the positioning component and the rotor 14 assembly already assembled on it are separated from the fixed mounting base 6 on the other side, thereby leaving enough operating space for unloading the finished product.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
