[0018] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this utility model described herein. Furthermore, terms such as "comprising" and "having" mean that in addition to those already listed in "comprising" and "having," other unlisted contents may also be included; for example, a process, method, system, product, or device may include a series of steps or units, not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0021] Due to the angle of the drawing, some parts may not be drawn, but their positions and connections can be understood from the text descriptions.

[0022] like Figure 1 As shown, this utility model is a volute clamping fixture with an auxiliary support mechanism, including a base plate 1, on which a positioning component, an auxiliary support mechanism, and a clamping mechanism are installed.

[0023] like Figure 3 As shown, the auxiliary support mechanism includes a base 5 and a support rod 2. A spring seat 10 is connected to the base 5. The lower part of the support rod 2 slides vertically in the spring seat 10, and the upper part of the support rod 2 extends out of the spring seat 10. A spring 4 is provided below the support rod 2. The upper end of the spring 4 abuts against the support rod 2, and the spring 4 gives the support rod 2 an upward preload.

[0024] The base 5 is connected to the base plate 1 via an auxiliary support mounting block 9. The base 5 is L-shaped, with one side of the base 5 connected to the auxiliary support mounting block 9 by bolts, and the other side connected to the spring seat 10.

[0025] The top of the support rod 2 has a turbine lug positioning groove 2-1, which mates with the lug on the turbine 11. The lower part of the support rod 2 is adapted to the shape of the inner hole of the spring seat 10 to ensure the stability of the support rod 2 during sliding. In this embodiment, the lower part of the support rod 2 and the inner hole of the spring seat 10 are cylindrical.

[0026] The base 5 is provided with a spring positioning groove, and the lower part of the spring 4 is located in the spring positioning groove to prevent the spring 4 from swaying during compression.

[0027] To limit the height to which the support rod 2 rises and prevent it from dislodging the turbine 11 from its positioning point, a limiting pin 3 is installed in the spring seat 10. A limiting groove 2-2 is provided on the side of the support rod 2, and the positioning end of the limiting pin 3 is located within the limiting groove 2-2. When the spring 4 pushes the support rod 2 to a certain height, the positioning end of the limiting pin 3 contacts the bottom of the limiting groove 2-2, preventing the support rod 2 from rising further.

[0028] To prevent the support rod 2 from moving down too much and damaging the spring 4, a limiting boss 2-3 is provided on the upper part of the support rod 2. The limiting boss 2-3 is located above the spring seat 10. When the lug on the bearing turbine 11 of the support rod 2 moves down too much, the limiting boss 2-3 contacts the top of the spring seat 10 to prevent the support rod 2 from applying excessive pressure to the spring 4.

[0029] To facilitate adjustment of the stroke of the support rod 2, an adjustment plate 12 is installed between the base 5 and the spring seat 10. The adjustment plate 12 has a through hole for the spring 2 to pass through. The thicker the adjustment plate 12, the shorter the downward stroke of the support rod 2.

[0030] The positioning assembly includes a bottom coarse positioning block 13 and a side positioning block 14. Several bottom coarse positioning blocks 13 are installed in the middle of the base plate 1, and the side positioning blocks 14 are located on the side of the bottom coarse positioning blocks 13.

[0031] The clamping mechanism includes a vertical clamping assembly and a horizontal clamping assembly. The vertical clamping assembly consists of several vertical clamping cylinders 8, and the horizontal clamping assembly includes a horizontal clamping cylinder 6.

[0032] To prevent the installation of several floating support cylinders 7 on the base plate 1 during the machining of the turbine 11.

[0033] The working process of this utility model is as follows: like Figure 2 As shown, the turbine 11 is placed on the bottom coarse positioning block 13 for coarse positioning, and the turbine 11 lug rests in the turbine lug positioning groove 2-1 at the top of the support rod 2. The horizontal clamping cylinder 6 pushes the turbine 11 to press against the side positioning block 14, and the vertical clamping cylinder 8 clamps the turbine 11 to adjust its position. After adjustment, the floating support cylinder 7 fixes the turbine 11. Finally, the turbine 11 is machined.

[0034] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
