Description

Technical Field

[0001] This application relates to the field of press fitting technology, specifically to a press fitting device for a water pump impeller. Background Technology

[0002] Impeller press-fitting is a crucial step in pump assembly. During press-fitting, the impeller is placed on the shaft end, and a press head presses it onto the pump shaft. Controlling the distance between the impeller and the pump casing mounting surface is essential. Currently, the industry solution is to install locating posts on both sides of the equipment to rigidly control the impeller press-fitting height. However, since the locating posts are fixed on both sides, they need to be replaced depending on the impeller's assembly position. This makes adjustment inconvenient, time-consuming, and inefficient during product testing. Furthermore, the impeller is prone to tilting during press-fitting, often causing damage to the shaft hole mating surface. Finally, the final assembly position of the impeller affects the overall pump performance.

However, this application can be implemented in many other ways different from those described below. Therefore, based on the embodiments provided in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0045] To facilitate understanding of the various embodiments of this application, the application background of the embodiments will be explained.

[0048] This application provides a pump impeller pressing device, including: a support base plate, a floating component, a guide component, a positioning component, and a laser ranging component. The guide component is vertically mounted on the support base plate. The floating component is connected to the guide component and can reciprocate vertically via the guide component. The floating component supports the pump body and moves towards the support base plate under external force. The positioning component is vertically positioned in the middle of the support base plate and is used to position the impeller.

[0050] Next, the pump impeller pressing device provided in this application will be described in detail with reference to the accompanying drawings. Figure 1 This is a perspective view of a water pump impeller press-fitting device provided in an embodiment of this application. Figure 2 This is a cross-sectional view from one angle of the water pump impeller pressing device provided in the embodiments of this application. Figure 3 This is a cross-sectional view from another angle of the water pump impeller press-fitting device provided in the embodiments of this application.

[0051] like Figures 1-3 As shown, this application provides a water pump impeller pressing device, including: a support base plate 1, a floating component 2, a guide component 3, a positioning component 5, and a laser ranging component 6. The guide component 3 is vertically mounted on the support base plate 1. The floating component 2 is connected to the guide component 3 and can reciprocate vertically via the guide component 3. The floating component 2 can support the pump body of the water pump 7 and move towards the support base plate 1 under external force. The positioning component 5 is vertically mounted in the middle of the support base plate 1 and is used to position the impeller 8. The laser ranging component 6 is mounted relative to the positioning component 5 on the side of the support base plate 1 and is used to measure the downward movement distance of the floating component 2 in real time. After the floating component 2 moves downward to a set value, the laser ranging component 6 feeds back a signal to prevent the floating component 2 from receiving further external force. The pump impeller pressing device is configured as follows: the impeller 8 is placed on the positioning component 5, and the pump body is placed on the floating component 2. An external force is applied to press the pump body downwards, causing the floating component 2 to move downwards along the guide component 3, pressing the pump shaft of the pump 7 into the impeller 8. After the laser ranging component 6 detects that the floating component 2 has moved to a set value, it sends a feedback signal to prevent the floating component 2 from receiving external force. Simultaneously, the floating component 2 moves upwards along the guide component 3 and resets.

[0052] Specifically, in this embodiment, the supporting base plate 1 has an overall cuboid structure. Guide components 3 are vertically arranged on the supporting base plate 1. In one example, four sets of guide components 3 are provided, with each set located at a corner of the supporting base plate 1. Each set of guide components 3 includes: a guide support 31, a guide shaft 32, and a first spring 33. The guide support 31 is located at a corner of the supporting base plate 1. In one example, the guide support 31 has a pedestal structure. The guide support 31 can be fixed to the supporting base plate 1 with bolts. The guide shaft 32 is vertically mounted on the guide support 31. The first spring 33 is fitted onto the guide shaft 32.

[0053] The floating component 2 is connected to the guide component 3 and can reciprocate vertically via the guide component 3. The floating component 2 can support the pump body of the water pump 7 and move towards the supporting base plate 1 under the action of external force. Specifically, in this embodiment, the floating component 2 includes a floating plate 21 and a linear bearing 22. The linear bearing 22 is fitted onto the guide shaft 32, and the abutting end of the linear bearing 22 abuts against one end of the first spring 33. Specifically, corresponding to the number of guide components 3, the number of linear bearings 22 is also set to 4. The linear bearing 22 can reciprocate vertically via the guide shaft 32. The floating plate 21 is connected to the linear bearing 22 to move synchronously with the linear bearing 22. In one example, the floating plate 21 is plate-shaped, and its coverage area is similar to that of the supporting base plate 1. The floating plate 21 has a through hole in the middle, which is used to install the impeller 8 on the positioning component 5 and to assemble the impeller 8 with the water pump 7. The floating plate 21 can support the pump body of the water pump 7 and move towards the supporting base plate 1 under the action of external force. During the movement of the floating plate 21 towards the supporting base plate 1, the abutting end of the linear bearing 22 abuts against one end of the first spring 33, causing the first spring 33 to be compressed and thus have a restoring elastic force. When the external force on the floating plate 21 disappears, the restoring elastic force of the first spring 33 drives the linear bearing 22 to move the floating plate 21 upward synchronously along the guide shaft 32 to reset.

[0054] In one example, the external force can be provided by the pressure head or by other driving mechanisms.

[0055] In this embodiment, to prevent the floating component 2 from detaching from the guide shaft 32 when it moves upward along the guide shaft 32, a limiting component 4 is also provided. The limiting component 4 is connected to the guide component 3 and located at the limiting end of the linear bearing 22. The limiting component 4 is used to limit the floating component 2. The limiting component 4 is provided for each linear bearing 22. Specifically, in one example, the limiting component 4 includes an end plate 41 and a bolt post 42. The bolt post 42 is connected to the guide shaft 32 in the vertical direction and protrudes from the limiting end of the linear bearing 22, specifically protruding from the limiting end of the linear bearing 22 along the shaft hole of the linear bearing 22. The end plate 41 is fitted onto the bolt post 42 and can abut against the limiting end of the linear bearing 22 to limit the linear bearing 22 when the limiting end of the linear bearing 22 abuts against the end plate 41. In one example, the end plate 41 can be configured as a disk shape, and the diameter of the end plate 41 is larger than the diameter of the shaft hole of the linear bearing 22. Of course, in other examples, end plate 41 can also be a square plate.

[0056] The positioning component 5 is vertically positioned in the middle of the support base plate 1 and is used to position the impeller 8. Specifically, in this embodiment, the positioning component 5 includes: a positioning seat 51, a receiving hole 52, a receiving groove 53, a positioning shaft 54, a second spring 55, and a guide sleeve 56. The positioning seat 51 is vertically positioned in the middle of the support base plate 1. In one example, the positioning seat 51 is configured as a column structure. The receiving groove 53 is recessed at the top of the positioning seat 51, and the receiving hole 52 is vertically recessed at the bottom of the receiving groove 53 and located in the middle of the positioning seat 51. The second spring 55 is installed in the receiving hole 52. The guide sleeve 56 is installed in the receiving groove 53. The positioning shaft 54 ​​is fitted onto the guide sleeve 56 and reciprocates vertically, abutting against the second spring 55. The positioning shaft 54 ​​is used to position the impeller 8.

[0057] When the positioning shaft 54 ​​carries the impeller 8 and moves downward in the vertical direction, the positioning shaft 54 ​​compresses the second spring 55, so that the second spring 55 has a restoring force. After the pump shaft of the water pump 7 is pressed into the impeller 8, the impeller 8 can be moved upward in the vertical direction and reset by the restoring force of the second spring 55.

[0058] The laser ranging component 6 is positioned relative to the positioning component 5 on the side of the supporting base plate 1. It is used to measure the downward movement distance of the floating component 2 in real time. After the floating component 2 moves downward to a set value, the laser ranging component 6 sends a feedback signal to prevent the floating component 2 from receiving external force. Specifically, in this embodiment, the laser ranging component 6 includes a switch base 61 and a laser rangefinder 62. The switch base 61 is positioned relative to the positioning component 5 on the side of the supporting base plate 1, and the laser rangefinder 62 is mounted relative to the positioning component 5 on the switch base 61. The laser rangefinder 62 is used to measure the downward movement distance of the floating component 2 in real time. After the floating component 2 moves downward to a set value, the laser ranging component 6 sends a feedback signal to prevent the floating component 2 from receiving external force. In one example, the laser rangefinder 62 preferentially uses the floating plate 21 as the measurement target.

[0059] This application provides a water pump impeller pressing device, including: a supporting base plate 1, a floating component 2, a guiding component 3, a positioning component 5, and a laser ranging component 6. The guiding component 3 is vertically mounted on the supporting base plate 1. The floating component 2 is connected to the guiding component 3 and can reciprocate vertically via the guiding component 3. The floating component 2 supports the pump body of the water pump 7 and moves towards the supporting base plate 1 under external force. The positioning component 5 is vertically mounted in the middle of the supporting base plate 1 and is used to position the impeller 8. The laser ranging component 6 is positioned relative to the positioning component 5 on the side of the supporting base plate 1 and is used to measure the downward movement distance of the floating component 2 in real time. After the floating component 2 moves downward to a set value, the laser ranging component 6 provides a feedback signal to prevent the floating component 2 from receiving further external force. The pump impeller pressing device is configured as follows: the impeller 8 is placed on the positioning component 5, and the pump body is placed on the floating component 2. An external force is applied to press the pump body downwards, causing the floating component 2 to move downwards along the guide component 3, pressing the pump shaft of the pump 7 into the impeller 8. After the laser ranging component 6 detects that the floating component 2 has moved to a set value, it sends a feedback signal to prevent the floating component 2 from receiving external force. Simultaneously, the floating component 2 moves upwards along the guide component 3 and resets.

[0060] In essence, the pump impeller press-fitting device provided in this application uses the laser ranging component 6 to measure the press-fitting height of each impeller 8 to the pump body in real time, thereby improving the assembly accuracy of the impeller 8, ensuring product quality, and reducing the product defect rate. Furthermore, the impeller 8 is placed on the positioning component 5 to ensure the concentricity of the impeller 8 hole and the pump shaft during the press-fitting process, preventing damage to the inner hole of the impeller 8 during press-fitting. In addition, the automated operation mode further improves the production and debugging efficiency of the pump 7 and impeller 8 press-fitting.
