Description

Technical Field

[0001] This utility model relates to the field of fuel pump assembly technology, specifically a fuel pump assembly tooling. Background Technology

[0002] The fuel pump mainly consists of a cylindrical housing and front and rear end caps. One end cap is responsible for drawing in fuel, and the other end cap is responsible for delivering fuel outwards. Figure 6 and Figure 7 As shown, the cylindrical housing (i.e., the pump housing in this application) is mostly made of aluminum alloy. Since the fuel pump works in the fuel tank for a long time, ensuring the firmness between the cylindrical housing and the end cap is of paramount importance. Therefore, in order to avoid the possibility of loosening, the end cap is directly screwed on to seal it. This can prevent the bolt connection from loosening and allow the fuel pump to operate stably for a long time.

[0003] For example Figure 6 and Figure 7 As shown, due to the relatively small size of the fuel pump, manual screw sealing is difficult, and the sealing process can only be performed one at a time on both ends of the cylindrical shell, making it impossible to form a complete unit and resulting in cumbersome steps. Therefore, we propose a fuel pump assembly fixture. Utility Model Content

[0004] This utility model provides a fuel pump assembly fixture, which has the advantage of being able to seal both ends of the pump body housing in one go, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A fuel pump assembly fixture is designed, including a support platform. The top of the support platform is provided with a clamping mechanism for clamping the pump body shell. Lifting mechanisms are provided on both sides of the clamping mechanism. A mounting seat is provided below the lifting mechanism. The two mounting seats are located at both ends of the pump body shell. A mounting shaft is rotatably installed in each mounting seat. A drive motor connected to the mounting shaft is installed on the side of the two mounting seats that are far apart from each other. An L-shaped support arm is installed on the opposite end of the two mounting shafts. A spinning wheel is installed on the end of the L-shaped support arm. The positions of the two spinning wheels correspond to the two ends of the pump body shell. In the initial state, the two spinning wheels are respectively positioned directly above the two ends of the pump body shell.

[0006] Preferably, the lifting mechanism includes a first L-shaped frame disposed on both sides of the clamping mechanism, a second telescopic mechanism is installed on the top of the first L-shaped frame, the telescopic shaft of the second telescopic mechanism is vertically downward, and the mounting seat is installed at the bottom of the second telescopic mechanism.

[0007] Preferably, at least one second guide shaft parallel to the second telescopic mechanism is installed on one side of the mounting base, the top of the second guide shaft is movably placed inside the guide seat, and the guide seat is set on the first L-shaped frame.

[0008] Preferably, the clamping mechanism includes a second L-shaped frame mounted on a support platform, a third telescopic mechanism mounted on the top of the second L-shaped frame, the telescopic shaft of the third telescopic mechanism being vertically downward, a clamping seat mounted at the bottom of the third telescopic mechanism, a placement seat below the clamping seat, the placement seat being fixed on the second L-shaped frame, and arc-shaped grooves matching the pump body housing being provided on the opposing surfaces of the placement seat and the clamping seat, the pump body housing being clamped in the arc-shaped grooves.

[0009] Preferably, at least one third guide shaft parallel to the third telescopic mechanism is installed on the top of the clamping seat, and the top of the third guide shaft is movably placed inside the guide seat, which is set on the second L-shaped frame.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1 to 5 This utility model provides a technical solution: a fuel pump assembly fixture, including a support platform 1, the top of which is provided with a clamping mechanism for clamping the pump body housing 20, such as... Figure 1 and Figure 2 As shown, the clamping mechanism includes a second L-shaped frame 16 mounted on a support platform 1. A third telescopic mechanism 15 is mounted on the top of the second L-shaped frame 16. The telescopic shaft of the third telescopic mechanism 15 is vertically downward. A clamping seat 6 is mounted on the bottom of the third telescopic mechanism 15. At least one third guide shaft 14 parallel to the third telescopic mechanism 15 is mounted on the top of the clamping seat 6. The top of the third guide shaft 14 is movably placed inside the guide seat. The guide seat is set on the second L-shaped frame 16. The third guide shaft 14 can enhance the stability of the clamping seat 6.

[0025] A placement seat 5 is located below the clamping seat 6, and the position of the placement seat 5 corresponds to the position of the clamping seat 6. The placement seat 5 is fixed on the second L-shaped frame 16. When the third telescopic mechanism 15 drives the clamping seat 6 to descend, the clamping seat 6 is positioned above the placement seat 5. Both the placement seat 5 and the clamping seat 6 have arc-shaped grooves that match the pump body housing 20 on their opposing surfaces. In specific operation, the pump body housing 20 is placed in the arc-shaped groove, and then the third telescopic mechanism 15 is controlled to drive the clamping seat 6 to descend, so that the pump body housing 20 is clamped in the arc-shaped groove. When the third telescopic mechanism 15 drives the clamping seat 6 to rise, the pump body housing 20 can be removed from the clamping seat 6.

[0026] Furthermore, lifting mechanisms are provided on both sides of the clamping mechanism, specifically on both sides of the second L-shaped frame 16, with mounting bases 9 located below the lifting mechanisms. Figure 1 and Figure 2 As shown, the lifting mechanism includes a first L-shaped frame 13 disposed on both sides of the clamping mechanism. A second telescopic mechanism 12 is installed on the top of the first L-shaped frame 13. The telescopic shaft of the second telescopic mechanism 12 is vertically downward. Specifically, the mounting seat 9 is installed at the bottom of the second telescopic mechanism 12. In order to make the up-and-down lifting of the mounting seat 9 more stable, at least one second guide shaft 11 parallel to the second telescopic mechanism 12 is installed on one side of the mounting seat 9. The top of the second guide shaft 11 is movably placed in the guide seat. The guide seat is disposed on the first L-shaped frame 13. The second guide shaft 11 can increase the stability of the mounting seat 9.

[0027] Furthermore, such as Figure 3 and Figure 4 As shown, the two mounting seats 9 are located at both ends of the pump body housing 20, and a mounting shaft 8 is rotatably mounted in each mounting seat 9. A drive motor 10 connected to the mounting shaft 8 is mounted on the side of the two mounting seats 9 that is far apart from each other. The drive motor 10 is used to drive the mounting shaft 8 to rotate. It should be noted that the central axis of the mounting shaft 8 and the central axis of the pump body housing 20 are in the same plane.

[0028] L-shaped support arms 17 are mounted on opposite ends of the two mounting shafts 8. The L-shaped support arms 17 are also located in the plane of the central axis of the pump body housing 20, and spinning wheels 19 are mounted on the ends of the L-shaped support arms 17. It should be emphasized that the positions of the two spinning wheels 19 correspond to the two ends of the pump body housing 20, and in the initial state, the two spinning wheels 19 are respectively positioned directly above the two ends of the pump body housing 20. When the second telescopic mechanism 12 drives the mounting base 9 to descend, the spinning wheels 19 are just placed on the two ends of the pump body housing 20. At this time, the mounting shafts 8 and the pump body housing 20 are coaxial. Then, the drive motor 10 is controlled to drive the spinning wheels 19 to rotate around the edge of the pump body housing 20, so that the spinning wheels 19 travel around the edge of the pump body housing 20 once, so that the two ends of the pump body housing 20 form an inward-curving shape.

[0029] Based on the above embodiments, before clamping the pump body housing 20, it is necessary to position the pump body housing 20, such as... Figure 3 and Figure 4 As shown, after installing the end caps inside both ends of the pump body housing 20, the two ends of the pump body housing 20 are then placed inside the U-shaped baffle 2 with the opening facing upward, so that the end caps at both ends of the pump body housing 20 are limited and blocked by the U-shaped baffle 2.

[0030] The bottom of the U-shaped baffle 2 is vertically provided with a first telescopic mechanism 4, which is installed in the support platform 1. The bottom of the U-shaped baffle 2 is vertically provided with at least one first guide shaft 3 parallel to the first telescopic mechanism 4. The first guide shaft 3 is movably arranged in the support platform 1. The first guide shaft 3, like the second guide shaft 11 and the third guide shaft 14, plays a stabilizing role, that is, to make the up-and-down movement of the U-shaped baffle 2 more stable. When the first telescopic mechanism 4 is shortened, the first telescopic mechanism 4 drives the U-shaped baffle 2 to descend below the placement seat 5 to avoid contact with the rotating L-shaped support arm 17.

[0031] This application also includes a clamping telescopic mechanism 7 coaxially mounted on one end of the two mounting shafts 8. Each telescopic end of the clamping telescopic mechanism 7 is rotatably mounted with a stop 18. When the clamping telescopic mechanism 7 is shortened, there is a certain gap between the stop 18 and the pump body housing 20.

[0032] Based on the above embodiments, the specific operation process is as follows: 1. First, install end caps inside both ends of the pump body housing 20. In the initial state, the U-shaped baffle 2 is in the raised state, and the pump body housing 20 is placed in the placement seat 5. At this time, both ends of the pump body housing 20 can be limited by the U-shaped baffle 2 to prevent the end caps from falling off.

[0033] 2. Control the third telescopic mechanism 15 to drive the clamping seat 6 to descend and clamp the pump body shell 20 to fix it;

[0034] 3. Control the second telescopic mechanism 12 to drive the mounting base 9 to descend, so that the spinning roller 19 presses on both ends of the pump body shell 20. Then control the clamping telescopic mechanism 7 to extend and drive the stop seat 18 to move closer to both ends of the pump body shell 20. At the same time, the first telescopic mechanism 4 drives the U-shaped baffle 2 to descend, so that both ends of the pump body shell 20 are exposed. Therefore, both ends of the pump body shell 20 are immediately pressed by the stop seat 18.

[0035] 4. Based on point 3, the spinning roller 19 is now pressed against the two end edges of the pump body housing 20. Then, the drive motor 10 can be controlled to rotate the mounting shaft 8 and the L-shaped support arm 17, allowing the spinning roller 19 to travel one revolution around both ends of the pump body housing 20, thus forming a shape at both ends of the pump body housing 20. Figure 6 and Figure 7As shown, the two ends of the pump body housing 20 are formed into an inward buckle shape, thereby sealing and fixing the end caps at both ends of the pump body housing 20, so that the end caps can be stably fixed inside the pump body housing 20 without loosening.

[0036] Based on the above embodiments, it should be further explained that the clamping telescopic mechanism 7, the first telescopic mechanism 4, the second telescopic mechanism 12, and the third telescopic mechanism 15 are cylinders, electric cylinders, or hydraulic cylinders, the support platform 1 is a cabinet, the components controlling the telescopic mechanism are installed inside the support platform 1, and a PLC logic control system is also set inside the support platform 1, so that the PLC logic control system is connected to the clamping telescopic mechanism 7, the first telescopic mechanism 4, the second telescopic mechanism 12, and the third telescopic mechanism 15 respectively, so that each component can operate according to the set route.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
