Description

A tooling for machining a booster pump Technical Field

[0001] This utility model relates to the field of booster pump technology, and in particular to a booster pump machining tooling. Background Technology

[0002] A booster pump typically consists of a motor, a volute casing, and an inlet flange. The impeller is housed within the volute casing and connected to the motor's output. The inlet flange connects to the liquid inlet of the volute casing, and a drain port is located at the liquid outlet of the volute casing. During assembly, the volute casing is connected to the motor with multiple bolts, and the volute casing is also connected to the inlet flange with multiple bolts. Aligning the bolts requires manual alignment of the connecting holes, which is time-consuming and labor-intensive, reducing assembly efficiency. Summary of the Invention

[0003] This utility model proposes a tooling for processing booster pumps, which facilitates direct alignment of the booster pump's connection holes without manual adjustment, thereby facilitating the direct installation of multiple bolts and improving assembly efficiency.

[0004] The technical solution of this utility model is implemented as follows: A booster pump processing fixture includes a worktable, a motor positioning assembly is provided at the upper end of the worktable, a transversely sliding volute positioning assembly is provided on the right side of the motor positioning assembly, the volute positioning assembly includes a sliding base plate, an arc-shaped support is fixed on the sliding base plate, a drain port support is fixed on the sliding base plate in front of the arc-shaped support, the drain port support includes a vertical rod, a support plate is fixed on the vertical rod, a longitudinally sliding positioning rod is provided on the vertical rod above the support plate, the support plate is used to support the lower side of the volute drain port, and the positioning rod is slidably placed inside the volute drain port.

[0005] Furthermore, a lateral sliding slide is provided on the right side of the volute positioning assembly, and a flange support is fixed on the slide. Both sides of the flange support are provided with detachable shafts, which are used to position the connection holes of the inlet flange.

[0006] Furthermore, the motor positioning assembly includes a positioning protrusion fixed to the worktable, with positioning pins fixed on both the front and rear sides of the worktable. Through the cooperation of the positioning protrusion and the positioning pins, the motor's position is directly positioned, fixing the position of its connection hole and facilitating subsequent docking of the volute.

[0007] Furthermore, a longitudinal guide cylinder is fixed on the vertical rod above the support plate. One end of the positioning rod slides through the guide cylinder and is fixed with a limit block. An insert block is provided at the other end of the positioning rod. A support spring is fitted on the positioning rod between the guide cylinder and the insert block.

[0008] Furthermore, positioning holes are provided on both sides of the flange support, and the shaft is inserted into the positioning holes. The shaft is connected to the flange support by a connecting rope. The connecting rope prevents the shaft from being lost.

[0009] The beneficial effects of this utility model are:

[0010] The processing fixture of this utility model, combined with the structural features of the booster pump, supports the main body of the volute through an arc-shaped support and positions the drain port through a drain port support. Since the position of the drain port is fixed, the volute is positioned so that the connecting holes can be directly aligned when it is assembled with the motor, without the need for manual adjustment. This facilitates the direct installation of multiple bolts and improves assembly efficiency.

[0011] This utility model supports the inlet flange with a flange support seat, and positions the connection hole at the bottom of the inlet flange with a shaft, so that when the inlet flange is connected to the volute, the connection hole is directly aligned, which facilitates the direct installation of multiple bolts.

Detailed Implementation

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] As shown in Figures 1 and 3-5, a booster pump processing fixture includes a worktable 1. A motor positioning assembly is provided at the upper end of the worktable 1. The motor positioning assembly includes a positioning protrusion 2, which is fixed on the worktable 1. Positioning posts 3 are fixed on both sides of the worktable 1, with two positioning posts 3 on each side, which correspond to the bolt holes 5 of the motor support 4. The positioning protrusion 2 corresponds to the central groove of the motor support 4. The position of the motor is positioned by the cooperation of the positioning protrusion 2 and the positioning posts 3.

[0022] A volute positioning assembly with a horizontal sliding mechanism is installed on the worktable 1 on the right side of the motor positioning assembly. The volute positioning assembly includes a sliding base plate 6, on which an arc-shaped support 7 is fixed. The arc-shaped support 7 supports the bottom of the volute 9. Two arc-shaped supports 7 are arranged horizontally at intervals, supporting the left and right sides of the bottom of the volute 9 respectively, improving the stability of the volute 9. To facilitate the subsequent connection of the first bolt 24 to the volute 9, the longitudinal width of the arc-shaped support 7 is smaller than the longitudinal distance between the two first bolts 24, supporting the bottommost part of the volute 9 without obstructing the position of the first bolt 24. A drain port support 8 is fixed on the sliding base plate 6 in front of the arc-shaped support 7, supporting the drain port of the positioning volute 9.

[0023] The method of using the booster pump machining fixture is as follows: place the motor support 4 on the positioning protrusion 2, and let the bolt hole 5 of the motor support 4 pass through the positioning post 3; then place the volute 9 on the arc-shaped support 7, place the drain port of the volute 9 on the drain port support 8, and then push the volute 9 toward the motor so that the output shaft of the motor is placed inside the volute 9 and connected to the impeller. The motor and the volute 9 are connected by the first bolt 24.

[0024] Example 2

[0025] This embodiment is basically the same as Embodiment 1, except that, as shown in Figures 1, 3, and 5, the drain outlet support 8 includes a vertical rod 10, a support plate 11 fixed on the vertical rod 10, and a longitudinally sliding positioning rod 12 provided on the vertical rod 10 above the support plate 11.

One end of the positioning rod 12 slides through the guide cylinder 13 and is fixed with a limit block 14. The other end of the positioning rod 12 is fixed with an insert block 15. A support spring 16 is fitted on the positioning rod 12 between the guide cylinder 13 and the insert block 15. By pulling the positioning rod 12 with the limit block 14, the support spring 16 is compressed. After the drain outlet 26 is placed on the support plate 11, the limit block 14 is released, the support spring 16 extends, and the insert block 15 is placed inside the drain outlet 26. The positioning of the drain outlet 26 achieves the positioning of the volute 9.

An arc groove 18 is provided at the upper end of the flange support seat 17. The longitudinal width of the arc groove 18 is smaller than the longitudinal distance between the two second bolts 25 of the inlet flange 20, so as not to obstruct the position of the connecting second bolts 25.

[0028] Positioning holes 22 are provided on the slides 19 on both sides of the flange support 17. The shaft 21 is inserted into the positioning holes 22 and the shaft 21 is connected to the flange support 17 by the connecting rope 23.
