Description

Technical Field

[0001] This utility model relates to the field of pump body processing, specifically to a positioning fixture for stainless steel inlet and outlet water sections. Background Technology

[0002] The stainless steel inlet and outlet sections are components within the pump body that introduce water into the impeller, provide the required flow pattern, collect the liquid flowing out of the impeller, and direct the liquid flow to the outlet. Currently, the reference surface for the positioning fixtures used by our company when assembling the stainless steel inlet and outlet sections is the side of the base. Since the side of the base is a non-machined surface and cannot be leveled during the positioning process, the alignment of the water section is time-consuming and relies heavily on the subjective judgment and assembly experience of the employees, posing a certain risk of misalignment. The existing technical solution has the following main drawbacks:

[0003] 1. The protective plastic plate between the assembly line operating table and the base is a movable part and cannot be used as a positioning reference surface;

[0004] 2. This fixture uses the side of the base as a positioning reference, which will create a certain gap with the working table surface, making it impossible to place stably and difficult to operate;

[0005] 3. The positioning fixture uses the side of the base as the reference surface. Since the side surface is a cast surface, the positioning accuracy is difficult to guarantee. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a positioning fixture for stainless steel inlet and outlet water sections. This fixture relies on a modular positioning slot to achieve alignment for different models and specifications of inlet and outlet water sections. Utilizing the machined surface of the operating table as a reference solves the problem of inaccurate positioning and allows for stable placement on the operating table for easy use. It offers accurate positioning, convenient operation, and high versatility; for different specifications of water sections, simply changing the positioning slot achieves water section alignment.

[0007] The purpose of this utility model is achieved through the following technical solution: This positioning fixture for stainless steel inlet and outlet water sections includes a fixture base plate, on which a pad is fixed. Two positioning plates are detachably installed on the pad. The positioning plates are L-shaped and symmetrically arranged, thus forming a U-shaped positioning groove between the two positioning plates for positioning and aligning the inlet and outlet water sections. The side of the fixture base plate away from the pad is bent to form a bent edge. The fixture base plate is placed on the processing surface of the operating table, and the bent edge fits against the outer edge of the operating table to achieve positioning.

[0008] As a further technical solution, a fixing hole is opened on each positioning plate, and a corresponding fixing hole with threads is also opened on the pad, so that the positioning plate and the pad are fixed by bolt connection.

[0009] As a further technical solution, a positioning hole is opened on each positioning plate, and a corresponding positioning hole is also opened on the pad to insert the positioning pin and position the positioning plate and the pad. A washer is set between the bolt head and the positioning plate to press the positioning pin.

[0010] As a further technical solution, a handle is fixed on the side of the tooling base plate away from the pad block.

[0011] As a further technical solution, at least one hollow hole is opened on the tooling base plate to achieve weight reduction.

[0012] As a further technical solution, the operating table is provided with several positioning columns for positioning the base of the pump body. A protective plastic plate is set between the base and the operating table. After the inlet and outlet water sections are positioned and corrected by positioning slots, they are placed on the base.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The positioning plate and pad are detachable and highly versatile, and the alignment of different specifications of inlet and outlet water sections can be completed by replacing the positioning plate;

[0015] 2. Using the machining surface of the operating table as the reference surface, place the fixture base plate directly on the machining surface of the operating table, and at the same time use the bent edge of the fixture base plate to fit and position it against the outer edge of the operating table to better ensure alignment accuracy.

[0016] 3. The tooling can be placed flat on the table, making operation more convenient;

[0017] 4. The positioning plate and the pad are first positioned by positioning pins to determine the distance on one side, then connected with bolts, and the positioning pins are pressed with washers for more accurate positioning. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings:

[0024] Example: As attached Figures 1-4 As shown, this stainless steel inlet / outlet water section positioning fixture includes a fixture base plate 1, a pad 2, a positioning plate 3, a positioning pin 4, a positioning hole 5, a fixing hole 6, a bolt 7, a washer 8, a positioning slot 9, a handle 10, a hollow hole 11, an inlet / outlet water section 12, a base 13, a protective plastic plate 14, a positioning column 15, an operating table 16, an outer edge 17, and a bent edge 18.

[0025] Reference Appendix Figure 1 , 2 A pad 2 is welded to the base plate 1 of the tooling, and two positioning plates 3 can be detachably installed on the pad 2. Figure 3 As shown, the positioning plates 3 are L-shaped and symmetrically arranged, forming a U-shaped positioning groove 9 between the two positioning plates 3, which can position and correct the inlet and outlet water sections 12. Furthermore, a fixing hole 6 is provided on each positioning plate 3, and a corresponding fixing hole 6 with threads is also provided on the pad 2, so that the positioning plate 3 and the pad 2 are connected and fixed by bolts 7. A positioning hole 5 is provided on each positioning plate 3, and a corresponding positioning hole 5 is provided on the pad 2. A positioning pin 4 is inserted into each positioning hole 5 to position the positioning plate 3 and the pad 2. A washer 8 is placed between the head of the bolt 7 and the positioning plate 3. After the bolt 7 locks the washer 8, the washer 8 presses the positioning pin 4.

[0026] like Figure 1 , 2 As shown in Figure 4, the side of the tooling base plate 1 away from the pad block 2 is bent at 90° to form a bent edge 18. The tooling base plate 1 is placed on the processing surface of the operating table 16. At the same time, the bent edge 18 fits against the outer edge 17 of the operating table 16 to achieve positioning. The operating table 16 is provided with several positioning posts 15, which can position the base 13 of the pump body. A protective plastic plate 14 is set between the base 13 and the operating table 16. After the inlet and outlet water sections 12 are positioned and corrected by the positioning slots 9, they are placed on the base 13.

[0027] Preferably, a handle 10 is welded and fixed to the tooling base plate 1 on the side away from the pad block 2. At least one hollow hole 11 is opened in the tooling base plate 1 to reduce the overall weight.

[0028] The working process of this utility model is as follows: Before calibration and positioning, the pump body base 13 is first positioned on the protective plastic plate 14 of the operating table 16 by the positioning pin 15. Then, according to the specifications of the inlet and outlet water sections 12, a suitable positioning plate 3 is selected. The positioning plate 3 is first positioned with the pad block 2 by the positioning pin 4, and then tightened and fixed by the bolt 7 and washer 8. After the positioning fixture is installed, the fixture base plate 1 is placed on the processing surface of the operating table 16 by the handle 10, and at the same time, the bent edge 18 is made to fit with the outer edge 17 of the operating table 16 to achieve positioning. After the inlet and outlet water sections 12 are positioned and calibrated by the positioning slot 9, they can be placed on the base 13 for subsequent processing.
