Description

Technical Field

[0001] This utility model relates to the field of fracturing pump valve box processing technology, specifically a fracturing pump valve box discharge hole processing and positioning device. Background Technology

[0002] In the petroleum, chemical, metallurgical, and machinery industries, fracturing pump valve boxes are among the most critical pieces of equipment. As a vital component in oil extraction and production enhancement operations, fracturing pump valve boxes are widely used in oilfields, gas fields, and other resource and production enhancement projects, making their production process a subject of close scrutiny. The rough machining of fracturing valve boxes involves large traditional machining equipment such as CNC lathes, drilling machines, and milling machines, which perform cutting, drilling, and grinding / polishing functions, respectively. While CNC drilling machines can perform rough machining of discharge holes for fracturing pump valve boxes of different sizes, their limitation lies in the complex adjustments required when machining discharge holes of different sizes. These adjustments include moving positioning blocks, limiters, and baffles, adjusting the horizontal and vertical positions of the spindle, and selecting the appropriate drill bit type. This significantly reduces productivity and creates machining difficulties.

[0003] Chinese invention patent CN222493979U designs a bolt machining positioning seat. Its worktable features a U-shaped steel frame and a slider. In actual production, the bolt is placed inside the U-shaped steel frame, and then the slider moves the bolt until it fully contacts the C-shaped groove, thus achieving bolt positioning. The fixed bolt is then processed. Chinese invention patent CN222492472U discloses a gear machining positioning table. A connecting box is fixed to the lower surface of the worktable for positioning and fixing gears. This allows for positioning gears with different inner diameters, improving gear machining efficiency and practicality. While the positioning methods in the above patents are practical and novel, and can be adaptively adjusted according to the size of the workpiece, they still cannot achieve efficient and convenient adjustment when applied to the positioning machining of holes in fracturing pump valve boxes of different sizes, and machining remains difficult. Therefore, to solve these problems, we propose a fracturing pump valve box discharge hole machining positioning device. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Please see Figures 1-13 A fracturing pump valve box discharge hole machining and positioning device includes a base 1, a T-shaped baffle 15, an L-shaped baffle 16, and a pin 18. A support platform 2 is mounted on the top of the base 1. A positioning sleeve 11 is embedded in the center of the bottom of the support platform 2. A drive motor 14, which is a reactive stepper motor, is embedded in the center of the top of the base 1. The output end of the drive motor 14 extends into the interior of the positioning sleeve 11. Two mutually perpendicular tracks 3 are installed on the top of the support platform 2. The tracks 3 are used for horizontal displacement in the X and Y directions, respectively. Positioning grooves 7 are respectively opened at both ends of one side of the top of the track 3. The track 3 is equipped with a positioning clamp 4 and a top positioning component 5. A slide rail movement limit position limiter 6 is installed on one side of the top of the track 3, and two drill bit feed depth limiters 10, several positioning sliders 9 and limit plates 8 are installed on the other side of the top of the track 3. The slide rail movement limit position limiter 6 is also installed on the track 3 by means of pins 18. The drill bit feed depth limiter 10 further limits the drill bit feed depth when processing the discharge hole of the fracturing pump valve box. The slide rail movement limit position limiter 6 plays a role in restraining the horizontal movement of the track 3 and preventing it from exceeding the limit displacement distance and colliding with the protective shell of the device. T-shaped baffles 15 and L-shaped baffles 16 are used for positioning different types of fracturing pump valve boxes during discharge hole machining. During discharge hole machining, both T-shaped baffles 15 and L-shaped baffles 16 are installed on the track 3 by bolts 17 and pins 18. The positioning slider 9 can be divided into a front slider and a rear slider according to its placement position, which are used to assist T-shaped baffles 15 and L-shaped baffles 16 and further fix the fracturing pump valve box.

[0033] As a technical optimization of this utility model, positioning blocks are connected to both sides of the bottom of the base 1. The top of the positioning blocks has a through-hole, and the inner wall of the positioning sleeve 11 is fixedly fitted onto the outside of the output end of the drive motor 14. Through the cooperation of the positioning blocks and the positioning holes, the base 1 can be easily positioned and installed using external positioning bolts, thereby improving the stability of the device.

[0034] As a technical optimization of this utility model, a number of guide rods 12 are connected to the outer side of the bottom of the support platform 2, and a rotating groove 13 is opened on the outer side of the top of the base 1. The bottom of the guide rods 12 extends into the interior of the rotating groove 13 and slides in contact with the interior of the rotating groove 13. Through the cooperation of the guide rods 12 and the rotating groove 13, the rotation of the support platform 2 can be limited to avoid large swings.

[0035] As a technical optimization of this utility model, the top of the drill bit feed depth limiter 10 is equipped with a bolt 17, and the bottom of the drill bit feed depth limiter 10 is installed on the top of the track 3 by a pin 18.

[0036] As a technical optimization of this utility model, the positioning component 5 includes a positioning block 51 and a positioning stud 52. The positioning block 51 is placed inside the positioning groove 7, and the bottom of the positioning stud 52 is connected to the top of the track 3. A lifting sleeve 55 is threaded onto the top of the positioning stud 52. Through the cooperation of the positioning block 51 and the positioning groove 7, the ruler plate 53 can be positioned, and the lifting plate 54 can be limited to prevent random rotation.

[0037] As a technical optimization of this utility model, a support cylinder 58 is connected to the bottom of the lifting screw sleeve 55. The support cylinder 58 is sleeved on the outside of the positioning stud 52. A lifting plate 54 is movably sleeved on the outside of the support cylinder 58 through a bearing. A ruler plate 53 is connected to the top of the positioning block 51, and the top of the ruler plate 53 passes through the lifting plate 54. Through the support cylinder 58, the lifting plate 54 can be rotated without rotating when the lifting screw sleeve 55 rotates. The lifting plate 54 is provided with a lifting socket for use with the ruler plate 53.

[0038] As a technical optimization of this utility model, an adjusting screw 56 is threaded through the center of one side of the top of the lifting plate 54. A connecting sleeve 59 is movably sleeved on the bottom of the adjusting screw 56 through a bearing. A pressure plate 57 is connected to the bottom of the connecting sleeve 59. Limiting slide rods 510 are connected to both ends of the top of the pressure plate 57. The top of the limiting slide rods 510 penetrates the lifting plate 54. The connecting sleeve 59 facilitates the rotation and lifting of the adjusting screw 56. The threads on the outside of the adjusting screw 56 are formed on the top of the connecting sleeve 59.

[0039] In use, the track 3 above the support platform 2 is adjusted to return to its initial position. The fracturing pump valve box to be processed is hoisted to the center of the top of the track 3. Then, the lifting plate 54 is rotated to move it directly above the fracturing pump valve box. The ruler plate 53 is moved down so that the positioning block 51 at its bottom engages with the positioning groove 7. Subsequently, the lifting screw sleeve 55 is rotated forward to move it down, thereby using the support cylinder 58 to drive the lifting plate 54 down until the bottom of the lifting plate 54 is placed on top of the fracturing pump valve box. At this point, the surface of the ruler plate 53 and the lifting plate 54 can be observed to indicate their position relative to the lifting plate 54. The corresponding value at the bottom of plate 54 indicates the height of the fracturing pump valve box. Subsequently, rotating the adjusting screw 56 downwards causes the pressure plate 57 to move downwards, repositioning the top of the fracturing pump valve box. This positioning method evenly distributes the cutting force during machining, reducing the risk of valve box vibration, especially ensuring machining stability during heavy cutting processes. Then, bolts 17 are used to install the T-shaped baffle 15 and L-shaped baffle 16 at the top corners of the fracturing pump valve box for fixation. Bolts 17 and pins 18 are used to secure the positioning fixture 4 (the type of positioning fixture 4 includes...). Figures 10-13 All types (specific shapes selected according to actual requirements) are installed in the remaining positions of the fracturing pump valve box to further secure it. Bolts 17 and pins 18 are used to install the drill bit feed depth limiter 10 and the slide rail movement limit position limiter 6 onto the rail 3, followed by discharge hole machining. During machining, if the angle of the support platform 2 needs to be changed, the external control terminal of the machining positioning device is used to control the drive motor 14 to rotate and fix the angle.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
