Description

Technical Field

[0001] This utility model relates to the field of impeller fixing fixture technology, and in particular to an impeller cold assembly fixing fixture. Background Technology

[0002] An impeller refers both to the wheel disk equipped with moving blades, which is a component of the rotor of an impulse steam turbine, and to the entire wheel disk and the rotating blades mounted on it.

[0003] However, in the existing technology, the structure of the impeller fixing fixture is relatively simple. It usually only has two movable clamping components to fix the impeller. The number of contact points between the clamping components and the impeller is small, which may result in the impeller clamping not being very stable. In addition, the height of the impeller exposed outside the clamping components cannot be adjusted, which is not convenient for the impeller assembly. Therefore, we propose an impeller cold assembly fixing fixture. Utility Model Content

[0004] This utility model provides a cold assembly and fixing fixture for impellers, which solves the above-mentioned technical problems.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A cold assembly and fixing fixture for an impeller includes a fixing plate. An mounting bracket is fixedly installed on the upper surface of the fixing plate via a bracket. A screw is threaded vertically through the middle of the mounting bracket. A lifting block is fixedly installed on the upper end of the screw. Multiple clamping components are installed on the upper surface of the mounting bracket via a sliding mechanism. A through groove is provided in the middle of the fixing plate. A movable adjusting ring is threadedly installed on the inner wall of the through groove. The upper end of the movable adjusting ring slides in cooperation with the lower surface of the clamping components.

[0006] Preferably, the sliding mechanism includes multiple sliding grooves equally spaced at an angle on the upper end face of the mounting frame, the sliding grooves are arranged through the mounting frame, and sliders are fixedly installed on the outer walls of both sides of the clamping member, the sliders being slidably connected to the inner walls of the sliding grooves.

[0007] Preferably, the plurality of clamping members surround the lifting block, and the lower surface of the clamping members is inclined.

[0008] Preferably, the lower end of the screw extends below the movable adjusting ring, and a knob is fixedly installed at the end of the screw.

[0009] Preferably, an adjustment handle is fixedly installed on the outer wall of the movable adjustment ring.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting and installing multiple movable clamping parts, rotating the lower movable adjustment ring can squeeze and push multiple clamping parts to move synchronously. The impeller in the middle is squeezed and fixed by multiple clamping parts, realizing multi-point contact fixation, which makes the fixation of the impeller more stable and simplifies the adjustment and control of the clamping parts.

[0012] 2. By setting a threaded screw, rotating the screw drives the upper support block to adjust the height, indirectly adjusting the part of the impeller exposed above the clamping part, making the assembly of the impeller more convenient.

[0020] The following is in conjunction with the appendix Figure 1-3 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0021] like Figure 1-3 As shown, this utility model discloses a cold assembly and fixing fixture for impellers, including a fixing plate 1. A mounting bracket 3 is fixedly installed on the upper end face of the fixing plate 1 via a bracket 2. A screw 4 is vertically threaded through the middle of the mounting bracket 3, and a lifting block 5 is fixedly installed on the upper end of the screw 4. Multiple clamping parts 6 are installed on the upper end face of the mounting bracket 3 via a sliding mechanism. The multiple movable clamping parts 6 can fix impellers of different models and specifications, and simultaneously provide multi-point contact fixing of the impellers, making the clamping and fixing of the impellers more stable. A through groove 7 is opened in the middle of the fixing plate 1, and a movable adjusting ring 8 is threaded on the inner wall of the through groove 7. The upper end of the movable adjusting ring 8 slides with the lower surface of the clamping parts 6. This device achieves multi-point fixing of the impeller by setting multiple clamping parts 6, making the clamping and fixing more stable. The clamping parts are controlled by the movable adjusting ring, simplifying the operation. At the same time, the lifting block 5 with adjustable height can be adjusted according to the impeller specifications to adjust the height of the exposed part of the impeller, making the impeller assembly more convenient.

[0022] Specifically, the sliding mechanism includes multiple sliding grooves 9 that are equally spaced at angles on the upper surface of the mounting frame 3. The sliding grooves 9 are set through the mounting frame 3. Slider blocks 10 are fixedly installed on the outer walls of both sides of the clamping member 6. The sliders 10 are slidably connected to the inner walls of the sliding grooves 9. The sliders 10 and the sliding grooves 9 are set to realize the installation connection between the clamping member 6 and the mounting frame 3, ensuring that the clamping member 6 can move laterally stably.

[0023] More specifically, multiple clamping parts 6 surround the lifting block 5. The lower surface of the clamping parts 6 is inclined to ensure the function of the moving adjustment ring 8. Rotating the moving adjustment ring 8 causes it to move upward. The clamping parts 6 can be pushed towards the center of the mounting frame 3 by the moving adjustment ring 8 to achieve the clamping and fixing of the impeller.

[0024] Furthermore, the lower end of the screw 4 extends below the movable adjustment ring 8, and a knob 11 is fixedly installed at the end of the screw 4. The knob 11 makes the rotation adjustment of the screw 4 more convenient. An adjustment handle 12 is fixedly installed on the outer wall of the movable adjustment ring 8. The adjustment handle 12 makes it convenient to control the rotation of the movable adjustment ring 8 for adjustment.

[0025] Working principle:

[0026] The impeller that needs to be fixed is placed on the support block 5. The screw 4 is rotated by the knob 11. The screw 4 rotates upward and drives the support block 5 to move upward, adjusting the height of the impeller so that the part of the impeller exposed above the clamping member 6 is easy to assemble. Then, the adjusting ring 8 is rotated by the adjusting handle 12, causing the adjusting ring 8 to move upward. The adjusting ring 8 pushes multiple clamping members 6 to move towards the middle of the mounting frame 3. The multiple clamping members 6 squeeze and fix the impeller, achieving stable squeezing and fixing of the impeller.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
