Description

Technical Field

[0001] This utility model relates to the field of fracturing pump valve box blank processing technology, and in particular to fracturing pump valve box blank cutting and fixing fixture. Background Technology

[0002] The shapes of fracturing pump valve box blanks are complex and diverse, and they play a crucial role in fracturing equipment in fields such as oil extraction, requiring high processing precision. During the cutting process, it is necessary to ensure that the blank is firmly fixed to guarantee the flatness and dimensional accuracy of the cut surface; otherwise, it will affect the subsequent assembly and performance of the valve box.

[0003] Most traditional fixed fixtures can only provide simple restriction on both sides of the fracturing pump valve box blank. This restriction method covers a limited area of ​​the blank, which makes the blank very prone to shaking during the cutting process due to factors such as cutting force. This leads to problems such as cutting size deviation and rough cutting surface, which seriously reduces the processing quality of the workpiece and increases the scrap rate. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a tooling for cutting and fixing fracturing pump valve box blanks. The specific technical solution is as follows:

[0005] A cutting and fixing fixture for fracturing pump valve box blanks includes a support base. The support base has multiple side plates distributed circumferentially. The side plates extend in a preset direction. Multiple limiting parts are provided on the inner side of the side plates along their extension direction. Each limiting part includes a movable frame provided on the side plate. The movable frame is equipped with an adjustable abutment and a rotating limiting plate with an arc-shaped side. The rotating limiting plate is rotatably connected to the movable frame.

[0006] When the blank is in the limited state, one side of the rotating limiting plate abuts against the blank. By adjusting the position of the abutting member on the movable frame, the abutting member abuts against and limits the other side of the rotating limiting plate, so as to limit multiple areas on the outer side of the blank.

[0007] As an improvement to the above technical solution: the abutting component includes a movable limiting plate and a threaded rod. The movable limiting plate is slidably connected to the inner side of the movable frame, and the threaded rod is threadedly connected to the movable frame. One end of the threaded rod is rotatably connected to the movable limiting plate, and the other end of the threaded rod extends to the outer side of the movable frame and is connected to a handle.

[0008] As an improvement to the above technical solution, it also includes a first moving part, which is used to drive the movable frame to move radially towards the support base. The side plate is provided with a guide hole, the movable frame is slidably connected in the guide hole, and a fixed frame is fixedly connected to the outer side of the side plate. The first moving part includes an electric telescopic rod installed on the fixed frame, and the output rod of the electric telescopic rod is fixedly connected to the movable frame.

[0009] As an improvement to the above technical solution, a second moving part is also included. The second moving part is used to push the side plate to move radially towards the support base. The second moving part includes a hydraulic cylinder installed on the support base, and the output rod of the hydraulic cylinder is fixedly connected to the side plate.

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

[0011] 1. This utility model, through the design of multiple side plates and multiple limiting parts on the side plates, greatly increases the limiting area on the outer surface of the blank. The rotating limiting plates abut against the blank from multiple directions, and precise adjustment and fixation are achieved through moving parts, effectively preventing the blank from shaking due to cutting forces and other factors during cutting. This ensures the positional stability of the blank during cutting, thereby significantly improving cutting accuracy, reducing cutting dimensional deviations and surface roughness, and improving product quality.

[0012] 2. The movable frame can adjust the position of the rotating limiting plate according to the specific size of the billet through the first moving part, so that it can better fit the outer side of the billet for limiting. At the same time, the side plate can move radially on the support base through the second moving part, further adjusting the overall containment and limiting range of the tooling for the billet. This allows the tooling to flexibly adapt to fracturing pump valve box billets of various sizes and shapes, greatly improving the versatility and practicality of the tooling, reducing the frequency of tooling changes due to billet size differences, and improving production efficiency.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Example

[0018] Please refer to Figures 1-2 A fracturing pump valve box blank cutting and fixing fixture includes a support base 1. The support base 1 has multiple side plates 2 distributed circumferentially. The side plates 2 extend in a preset (vertical) direction. The inner side of the side plates 2 is provided with multiple limiting parts along its extension direction. The limiting part includes a movable frame 6 provided on the side plate 2. The movable frame 6 is equipped with an adjustable abutment and a rotating limiting plate 9 with an arc-shaped side. The rotating limiting plate 9 is rotatably connected to the movable frame 6.

[0019] When the blank is in the limiting state, one side of the rotating limiting plate 9 abuts against the blank. By adjusting the position of the abutting member on the movable frame 6, the abutting member abuts against and limits the other side of the rotating limiting plate 9, so as to limit multiple areas on the outer side of the blank. Specifically, the vertical direction is the X direction in the figure, and the rotation direction of the rotating limiting plate 9 is the M direction in the figure.

[0020] Specifically, the fracturing pump valve box blank cutting and fixing fixture of this utility model mainly consists of a support base 1 as the basic support structure. On the support base 1, multiple side plates 2 extending vertically are evenly distributed in a circular array. These side plates 2 together form a circular space for accommodating and positioning the fracturing pump valve box blank.

[0021] Multiple limiting parts are arranged vertically on the inner side of each side plate 2. The limiting part is the key part for achieving precise positioning of the blank. It includes a movable frame 6, which is slidably connected to the side plate 2 through the guide hole 200 on the side plate 2, so that it can move radially on the side plate 2.

[0022] A movable component and a rotating limiting plate 9 are provided on the movable frame 6. The end of the rotating limiting plate 9 is arc-shaped and is vertically rotatably connected to the movable frame 6. When the blank is placed in position for the limiting operation, one end of the rotating limiting plate 9 first abuts against the outer surface of the blank. Then, by operating the movable component to move on the movable frame 6, the other side of the rotating limiting plate 9 abuts and limits the blank, thereby achieving limiting of the outer surface of the blank from two directions. Moreover, multiple limiting parts can limit multiple areas of the outer surface of the blank, effectively preventing the blank from shaking.

[0023] The moving part consists of a movable limiting plate 8 and a threaded rod 7. The movable limiting plate 8 is slidably connected to the inner side of the movable frame 6, allowing for smooth linear movement within the movable frame 6. The threaded rod 7 is threadedly connected to the movable frame 6, with one end rotatably connected to the movable limiting plate 8 and the other end extending to the outer side of the movable frame 6 and connected to a handle. By rotating the handle, the threaded rod 7 can be easily rotated. Due to the threaded fit between the threaded rod 7 and the movable frame 6, and its rotatable connection with the movable limiting plate 8, when the threaded rod 7 rotates, the movable limiting plate 8 will move axially along the threaded rod 7 within the movable frame 6, thereby achieving the abutment and limiting adjustment of the other end of the rotating limiting plate 9.

[0024] The main function of the first moving part is to drive the movable frame 6 to move radially on the side plate 2 to accommodate blanks of different sizes. The first moving part includes an electric telescopic rod 5 mounted on the outer fixing frame 4 of the side plate 2, and the output rod of the electric telescopic rod 5 is fixedly connected to the movable frame 6. When it is necessary to adjust the position of the movable frame 6, the electric telescopic rod 5 is activated, and the extension and retraction of its output rod can precisely drive the movable frame 6 to move radially along the side plate 2 within the guide hole 200, so that the rotating limiting plate 9 moves closer to or away from the blank, facilitating the limiting operation of the blank.

[0025] The second moving part is used to propel the side plate 2 radially on the support base 1, further enhancing the tooling's adaptability to blanks of different sizes and shapes. The second moving part consists of a hydraulic cylinder 3 mounted on the support base 1. The output rod of the hydraulic cylinder 3 is fixedly connected to the bottom end of the side plate 2, while the bottom end of the side plate 2 is slidably connected to the support base 1, ensuring that the side plate 2 can slide smoothly radially on the support base 1. By controlling the extension and retraction of the output rod of the hydraulic cylinder 3, the side plate 2 can be driven to move radially on the support base 1, allowing the size of the space enclosed by the multiple side plates 2 to be adjusted according to the size of the blank, in order to better accommodate and limit the blank.

[0026] During tooling assembly and debugging:

[0027] First, place the support base 1 stably on the workbench, ensuring its levelness meets requirements. Then, install multiple side plates 2 in a circular array on the support base 1, ensuring a good fit between the bottom end of the side plates 2 and the sliding connection part of the support base 1, allowing the side plates 2 to slide smoothly radially on the support base 1. Next, fix a mounting bracket 4 to the outside of each side plate 2, and install the electric telescopic rod 5 on the mounting bracket 4. Adjust the position of the electric telescopic rod 5 so that its output rod can accurately connect with the movable frame 6. Then, install the movable frame 6 onto the side plate 2 through the guide hole 200, ensuring the movable frame 6 can slide freely within the guide hole 200. Install a movable limiting plate 8 and a threaded rod 7 inside the movable frame 6, correctly connecting the threaded rod 7 to the movable limiting plate 8, and simultaneously install a handle on the outer end of the threaded rod 7. Finally, install a rotation limiting plate 9 on the movable frame 6, allowing it to rotate freely vertically.

[0028] When cutting the fracturing pump valve box blank, the blank is placed on the support base 1, within the space enclosed by multiple side plates 2. Based on the approximate size of the blank, the hydraulic cylinder 3 is activated, controlling the extension and retraction of the output rod to push the side plates 2 radially on the support base 1. This brings the rotating limiting plate 9 on the side plate 2 closer to the blank, initially adjusting the tooling's coverage area. Then, for each limiting part on the side plate 2, the handle is rotated to rotate the threaded rod 7, causing the movable limiting plate 8 to move within the movable frame 6. The angle of the rotating limiting plate 9 is adjusted so that one end of the rotating limiting plate 9 gently touches the outer surface of the blank. Next, the handle is rotated further, causing the movable limiting plate 8 to further contact and limit the other end of the rotating limiting plate 9, ensuring that the rotating limiting plate 9 can stably limit the blank. By performing the same operation on multiple limiting parts on multiple side plates 2, precise limiting of multiple areas on the outer side of the blank can be achieved, so that the blank can maintain a stable position in the tooling for subsequent cutting and processing operations.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
