Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, and in particular to a ceramic slurry pump impeller bonding and clamping fixture. Background Technology

[0002] In the field of high-end slurry pumps, an innovative "ceramic-metal composite" impeller structure has emerged to balance the extreme wear resistance of the impeller's flow components with the necessary mechanical strength of the overall structure. This structure typically uses high-performance ceramics (such as alumina and silicon carbide) as the erosion-resistant "skeleton" or liner, precisely bonded to a high-strength metal matrix skeleton, aiming to combine the superior wear resistance of ceramics with the excellent toughness of metal. However, this "strong combination" design faces far more severe challenges in manufacturing, especially in the bonding process, than with impellers made of single materials. The core challenge lies in the precision and reliability of the bonding process, creating an urgent need for specialized bonding tooling. Currently, many production sites still rely on the experience of skilled workers for bonding operations, resulting in poor quality consistency, low production efficiency, and high overall costs. Therefore, developing a specialized bonding tooling that integrates positioning and process protection is no longer a simple auxiliary tool requirement, but a core technological prerequisite for achieving large-scale, high-quality, and controllable production of ceramic-metal composite impellers. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings and defects of the existing technology by providing a ceramic slurry pump impeller bonding and clamping fixture, which solves the problems of inconsistent quality caused by relying on worker experience during the bonding process of ceramic and metal frames of ceramic slurry pumps, and its unsuitability for mass production.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: A ceramic slurry pump impeller bonding and clamping fixture includes a ground platform, a mounting bracket set on the ground platform, and a lifting device set on the mounting bracket. The bottom end of the lifting device is provided with a pressure plate, and the ground platform is provided with a plurality of positioning and assembly holes.

[0005] In a preferred embodiment of the present invention, the mounting bracket includes a pair of vertical sides spaced apart on the ground platform and a horizontal side disposed between the top ends of the pair of vertical sides, and the lifting device is disposed in the middle of the horizontal side.

[0006] In a preferred embodiment of this utility model, the bottom of the vertical side is detachably connected to the positioning assembly hole.

[0007] In a preferred embodiment of the present invention, the lifting device includes a threaded bushing that passes through the middle of the horizontal side and a screw threadedly connected to the threaded bushing. A handwheel is provided at the top of the screw, and a pressure plate is provided at the bottom of the screw.

[0008] In a preferred embodiment of the present invention, the lifting device includes a cylinder disposed at the bottom center of the horizontal side, and the telescopic end of the cylinder is connected to the pressure plate.

[0009] In a preferred embodiment of the present invention, the cylinder is provided with a first flange at its telescopic end, and the pressure plate is provided with a second flange corresponding to the first flange, and the first flange and the second flange are detachably connected.

[0010] In a preferred embodiment of this utility model, the horizontal and vertical sides are square steel.

[0011] By employing the above technical solution, this invention allows for a tighter bond between the ceramic and metal frames of the slurry pump impeller during the bonding process. This solves the problems of inconsistent quality and unsuitability for mass production caused by reliance on worker experience during the bonding of ceramic and metal frames in ceramic slurry pumps. Furthermore, this invention is simple to operate, minimizing reliance on specialized operators; anyone can operate it after simple training. Attached Figure Description

Detailed Implementation

[0018] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0019] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0020] It should be understood that although the terms "first," "second," "third," etc., may be used in this invention to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Example 1

[0021] See Figures 1 to 2 The ceramic slurry pump impeller bonding and clamping fixture shown includes a ground platform 100, a mounting bracket 200 mounted on the ground platform 100, and a lifting device 300 mounted on the mounting bracket 200. A pressure plate 400 is provided at the bottom end of the lifting device 300, and the ground platform 100 has several positioning and assembly holes 110. The positioning and assembly holes 110 can be used to position and fix the ceramic slurry pump impeller through positioning components.

[0022] The mounting bracket 200 includes a pair of vertical edges 210 spaced apart on the ground platform 100 and a horizontal edge 220 positioned between the top ends of the pair of vertical edges 210. A lifting device 300 is located in the middle of the horizontal edge 220. Preferably, the horizontal edge 220 and the vertical edges 210 are made of square steel. The bottom of the vertical edge 210 is detachably connected to the positioning mounting hole 110, allowing the position of the vertical edge 210 to be changed according to working conditions. In this embodiment, the lifting device 300 includes a threaded bushing 310 penetrating the middle of the horizontal edge 220 and a screw 320 threadedly connected to the threaded bushing 310. A handwheel 321 is located at the top of the screw 320, and a pressure plate 400 is located at the bottom of the screw 320.

[0023] The working principle of this utility model is as follows: When the ceramic slurry pump impeller 1 is being cast, it is placed on the ground platform 100, through the positioning assembly hole 110, and then placed on the vibrating table. By rotating the handwheel 321, the screw 320 drives the pressure plate 400 to press the impeller metal frame onto the impeller ceramic frame, ensuring a tight fit between the two. This solves the problems of inconsistent quality caused by reliance on worker experience during the bonding process of the ceramic and metal frames in ceramic slurry pumps, which makes it unsuitable for mass production. Furthermore, this utility model is simple to operate, minimizing reliance on professional operators; anyone can operate it after simple training. Additionally, because the pressure plate 400 presses the impeller metal frame onto the impeller ceramic frame, ensuring a tight fit, the impeller metal frame and impeller ceramic frame will not move arbitrarily on the vibrating table. Example 2

[0024] See Figure 3 and Figure 4 As shown, this embodiment is largely the same as Embodiment 1, except that the lifting device in this embodiment includes a cylinder 300' located in the middle of the horizontal side. The cylinder housing is fixed to the cylinder guide sleeve 310' in the middle of the horizontal side, and the telescopic end 301' of the cylinder is connected to the pressure plate 400'. Preferably, the telescopic end 301' of the cylinder 300' is provided with a first flange 302', and the pressure plate 400' is provided with a second flange 303' corresponding to the first flange 302'. The first flange 302' and the second flange 303' are detachably connected. In this embodiment, by selecting pressure plates of different sizes for impellers of different heights, the cylinder drives the pressure plates of different sizes to rise and fall. This also achieves the purpose of the pressure plate pressing the impeller metal frame onto the impeller ceramic frame, ensuring a tight fit and physical limitation to prevent damage to the ceramic impeller.

[0025] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0026] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0027] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
