[0037] As shown in Figures 1-6 A machine pump spare parts assembly tool, comprising a base 10, a placement table 20, a lifting piece 30, a pressing block 40, an adjusting rod 50 and a mounting seat 51; the base 10 is horizontally placed on the working surface, and the base 10 is horizontally provided with the placement table 20 above, and the placement table 20 is used for placing the pump cover A; the pressing block 40 is placed on the placement table 20, and the bottom of the pressing block 40 is rotatably connected with the table top of the placement table 20; the mounting seat 51 is vertically fixedly arranged on the placement table 20, and the bottom thereof is fixedly connected with the table top of the placement table 20; the adjusting rod 50 is arranged on the mounting seat 51, the peripheral portion of the adjusting rod 50 is screwed with the mounting seat 51, and the rod length direction of the adjusting rod 50 is consistent with the radial direction of the placement table 20; the fixed end of the lifting piece 30 is fixedly connected with the base 10, and the movable end of the lifting piece 30 is fixedly connected with the bottom of the placement table 20, and the movable end of the lifting piece 30 can drive the placement table 20 to approach or move away from the base 10.

[0038] The machine pump spare part assembly tool in the embodiment of the application is mainly applied to vertical machine pump assembly operation scene, and comprises a base 10, a placing table 20, a lifting piece 30, a pressing block 40, an adjusting rod 50 and a mounting seat 51. It should be noted that the machine pump spare parts in the application include a pump cover A, an impeller C and a rotating shaft B. The base 10 is horizontally placed on a working surface to ensure that the end surface of the impeller C is maintained in a horizontal state. The placing table 20 is kept at a certain horizontal interval from the base 10. Such a design not only provides sufficient space for maintenance personnel to check the wear of each spare part of the machine pump and perform assembly work, but also ensures the horizontal alignment of the end surface of the pump cover A and the impeller C, thereby simplifying the assembly and maintenance process. The lifting piece 30 drives the linear displacement of the placing table 20 in the vertical direction of the base 10, and the maintenance personnel lift the machine pump spare parts by the lifting piece 30. The setting of the pressing block 40 avoids the accidental separation of the pump cover A from the placing table 20 when the pump cover A is assembled with other machine pump spare parts (such as the rotating shaft B and the impeller C). The adjusting rod 50 is horizontally inserted into and vertically installed in the mounting seat 51 on the table top of the placing table 20, and the two are tightly connected through threaded connection. The maintenance personnel only need to simply twist the adjusting rod 50 to make it displace towards the center of the placing table 20 until it abuts against the side surface of the pump cover A. This operation not only helps to fine-tune the position of the pump cover A on the placing table 20 to ensure that the pump cover A can be accurately connected with the rotating shaft B, but also reduces the risk of collision between the pump cover A and other spare parts of the machine pump.

[0039] As shown in Figure 1 , it can be implemented that the number of the pressing block 40, the adjusting rod 50 and the mounting seat 51 in the application can be set to multiple, preferably, the number of the pressing block 40 and the adjusting rod 50 and the mounting seat 51 in the application is three, and the spacing is arranged on the table top of the placing table 20. The purpose is to form three-point constraint on the side surface and the top end surface of the pump cover A, so that the pump cover A is well constrained on the placing table 20.

[0040] The pressing block 40 comprises a vertical section 41, a rotating rod 43 and a horizontal section 42; the vertical section 41 is placed on the placing table 20 and is rotationally connected with the table top of the placing table 20; the rotating rod 43 vertically penetrates the middle part of the vertical section 41 and is fixedly connected with the placing table 20; one end of the horizontal section 42 is fixedly connected with the upper part of the vertical section 41, and the other end of the horizontal section 42 extends horizontally, and the lower end surface of the horizontal section 42 abuts against the upper end surface of the pump cover A.

[0041] As shown in Figure 1As shown, the pressing block 40 in the present application comprises a vertical section 41, a rotating rod 43 and a horizontal section 42, wherein the horizontal section 42 is fixedly connected to the upper part of the vertical section 41, and the rotating rod 43 vertically penetrates the vertical section 41 to constrain the vertical section 41 on the placing table 20. The vertical section 41 stably supports the horizontal section 42. The staff can rotate the horizontal section 42 around the rotating rod 43, so that the bottom end surface of the horizontal section 42 abuts against the top end surface of the pump cover A, to ensure the stable contact between the pump cover A and the placing table 20. Preferably, the pressing block 40 in the present application is in "L" shape structure. The horizontal section 42 and the rotating rod 43 can also be fixedly connected directly in the present application.

[0042] As shown in the figure, Figure 5 As shown, the middle part of the placing table 20 is provided with a placing hole 21, and the hole edge of the placing hole 21 and the table surface of the placing table 20 are in stepped structure, and the stepped surface abuts against the peripheral surface of the pump cover A. The purpose of such arrangement is to ensure the stable contact between the pump cover A and the placing table 20, and to avoid the damage of the peripheral surface of the pump cover A caused by the bouncing of the pump cover A during the lifting process.

[0043] As shown in the figure, Figure 4 In order to provide the placing space for the impeller C, the upper surface of the base 10 vertically extends with a mounting groove 11, and the groove cavity of the mounting groove 11 can accommodate the impeller C and constrain the relative position of the impeller C on the base 10, so as to facilitate the inspection and maintenance of the maintenance personnel and the installation of other machine pump spare parts.

[0044] As shown in the figure, Figure 4 As shown, the groove cavity of the mounting groove 11 vertically extends with a limiting groove 12 from the groove bottom; the groove cavity of the limiting groove 12 can accommodate the rotating shaft B. The purpose of such arrangement is to limit the fixed position of the rotating shaft B, to avoid the deviation of the rotating shaft B and the impeller C, and to ensure the stable assembly operation of the machine pump spare parts.

[0045] In order to ensure the accurate connection between the pump cover A and the impeller C during the descending process, the groove core of the mounting groove 11, the table core of the placing table 20 and the groove core of the limiting groove 12 are coaxially arranged, which also avoids the mutual knocking of the spare parts during the assembly process.

[0046] The lifting member 30 is in rod-like structure, and a plurality of lifting members 30 are arranged, and the lifting rates of the respective lifting members 30 are consistent. The purpose of arranging a plurality of lifting members 30 in the embodiment of the present application is to ensure that the table surface of the placing table 20 always remains horizontal while being stably connected with the lifting members 30 during the lifting process. Preferably, the number of the lifting members 30 in the present application is three, which are arranged in three-point mode at the bottom of the base 10. Such arrangement forms a three-point supporting structure between the placing table 20 and the base 10, and the lifting rates of the three lifting members 30 are at the same frequency, which avoids the overturning and damage of the placing table 20 during the lifting process of the lifting members 30, and further ensures the integrity of the machine pump spare parts structure and saves the production cost.

[0047] In practice, the lifting component 30 in this application is a telescopic cylinder. The purpose of using a telescopic cylinder is twofold: firstly, maintenance personnel can directly connect to the telescopic cylinder using an external air source, raising or lowering the placement platform 20 by inflating or deflating the cylinder, simplifying the drive program for the pump assembly tooling in this embodiment and reducing the workload of maintenance personnel; secondly, it eliminates concerns about liquid spillage contaminating the lifting component 30 during pump disassembly, or dust or debris contaminating the lifting component 30 and causing damage. Preferably, the operator can use a telescopic cylinder of the same specification and a matching generator to set the telescopic cylinder's extension / retraction rate.

[0048] To constrain the vertical displacement of the placement platform 20 and prevent the pump cover A from colliding with other pump components during the descent of the placement platform 20, a limiting block 31 is fixedly connected to the side of the lifting component 30 closest to the placement platform 20. The upper surface of the limiting block 31 is in the same horizontal plane as the plumb bob projection. This arrangement also ensures that the platform surface remains in the same plane when the placement platform 20 descends to the target workstation.

[0049] like Figure 2 and Figure 6 As shown, a guide tube 32 is provided around the outer periphery of the lifting component 30, and the guide path of the guide tube 32 is consistent with the lifting path of the lifting component 30. In the above scheme, the guide tube 32 is provided to prevent the lifting component 30 from deforming due to the weight of the pump cover A acting on the lifting component 30 rod, thereby ensuring the stability of the lifting component 30 structure. On the other hand, it is to further limit the lifting path of the lifting component 30 so as to ensure that the pump cover A on the placement platform 20 can be accurately moved to the target position, thereby completing the assembly operation of the pump spare parts and improving the assembly efficiency of the pump spare parts.

[0050] To ensure the structural strength of the clamping block 40, the vertical section 41 and the horizontal section 42 are an integral structure.

[0051] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0052] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
