[0002] In the oil field, high-pressure joints, as one of the key equipment, bear the heavy responsibility of connecting oil pipelines and transmitting high-pressure oil and gas. The stability and reliability of its performance are directly related to the safety and efficiency of the entire oil system. In recent years, with the continuous advancement of oil extraction technology, the design of high-pressure joints has become increasingly perfect. The new high-pressure joints not only have higher pressure resistance, but also have significant improvements in sealing and corrosion resistance. These improvements enable high-pressure joints to work stably in more severe environments, providing strong technical support for oil extraction.

[0003] In the processing of high-pressure joints, they need to be connected to the oil pipe before use. The connection between the high-pressure joint and the oil pipe must be able to withstand huge pressure to ensure that the oil can be transmitted safely and stably. The oil pipe needs to be armored with a fixture so that the oil pipe is positioned before connection processing to ensure that the connection between the high-pressure joint and the oil pipe is tight and reliable, and it is not easy to leak.

[0004] The patent "High-pressure plunger pump and hydraulic oil joint installation fixture" (publication number CN209304431U, hereinafter referred to as prior art 1) discloses a fixture that helps to install the high-pressure plunger pump and the hydraulic oil joint. In prior art 1, the shaft of the high-pressure plunger pump is fixed by the high-pressure plunger pump and hydraulic oil joint installation fixture, and the high-pressure hydraulic oil joint can be smoothly screwed into the shaft hole of the high-pressure plunger pump to successfully complete the hydraulic fitting.

[0026] Example 1

[0027] See also Figure 1The embodiment of the utility model provides a high-pressure joint processing fixture, including a working panel 11, a high-pressure joint 12 and an oil pipe 13; including a clamping mechanism and a fixture. The clamping mechanism is connected to the fixture through the top of the fixture; the clamping mechanism and the fixture are both arranged on a mounting plate 14. The mounting plate 14 is arranged on the working panel 11 through a plurality of foot pads 141. The clamping mechanism includes a clamping cylinder 21 and a clamping arm 22; the clamping arm 22 is connected to the cylinder through a first support seat 23 and a second support seat 24. The first support seat 23 and the second support seat 24 are respectively hinged to the two ends of the clamping arm 22; a clamping block 25 is provided at one end of the clamping arm 22. The clamping block 25 contacts the top of the fixture, and through the drive of the clamping cylinder 21, the clamping arm 22 generates a rotational motion based on the first support seat 23 and the second support seat 24, so that the clamping block 25 clamps the top of the fixture. The high-voltage connector processing fixture of the present application has the advantages of simple structure, convenient operation, high processing precision, etc., and is suitable for processing requirements of various specifications of high-voltage connectors 12. Through the positioning and clamping of the fixture, and the coordination of the displacement mechanism and the hole expansion module, efficient and precise processing of the high-voltage connector 12 can be achieved, thereby improving production efficiency and product quality.

[0028] See also Figure 2 The fixture includes an upper mold 31 and a lower mold 32; a positioning mold 33 is also provided at the bottom of the lower mold 32; the joint surfaces of the upper mold 31 and the lower mold 32 are respectively provided with a placement groove 15 adapted to the oil pipe 13; the upper mold 31, the lower mold 32, the clamping block 25 and the positioning mold 33 are respectively provided with positioning grooves. The setting of the positioning groove enables the fixture to accurately align and fix the oil pipe 13 and the high-pressure joint 12 during the processing, further improving the processing accuracy. At the same time, the positioning groove can also play a limiting role to prevent excessive displacement or deformation during the processing, thereby ensuring the processing quality.

[0029] A positioning block is provided in the positioning groove; the oil pipe 13 is clamped by the placement groove 15 provided by the upper mold 31 and the lower mold 32; the placement groove 15 is provided with an inlet end 151 and a processing end 152. The oil pipe 13 itself is a hose, which enters the installation groove through the inlet end 151 and extends out of the processing end 152. The oil pipe 13 has a certain extension length at the processing end 152. Furthermore, in order to ensure the smooth progress of the processing process, a guide device can be provided at the inlet end 151 of the fixture to guide the oil pipe 13 to accurately enter the placement groove 15, thereby avoiding errors during the installation process.

[0030] See also Figure 2, the positioning groove includes a first positioning groove 311 and a second positioning groove 312; the positioning grooves on the upper mold 31 and the clamping block 25 are combined to form the first positioning groove 311; the positioning grooves on the lower mold 32 and the positioning mold 33 are combined to form the second positioning groove 312; the positioning block includes a first positioning block 313 and a second positioning block 314; the first positioning block 313 and the second positioning block 314 are respectively arranged in the first positioning groove 311 and the second positioning groove 312. Specifically, the first positioning groove 311 and the second positioning groove 312 not only form a precise fit in the upper mold 31, the clamping block 25, the lower mold 32 and the positioning mold 33, but also make fine adjustments in size and shape. Such a design not only ensures the stability of the mold during the assembly process, but also greatly improves the positioning accuracy, thereby effectively avoiding the deviation or dislocation of the product during the production process. At the same time, in order to meet the production needs of different products, we also designed a first positioning block 313 and a second positioning block 314 with interchangeability. The two positioning blocks can be easily replaced between the first positioning groove 311 and the second positioning groove 312 according to actual production needs. This design not only improves the flexibility of production, but also reduces production costs, making the entire production process more efficient and convenient.

[0031] In addition, we have optimized the material selection of the positioning block. We have selected materials with high strength, high wear resistance and good thermal stability to make the positioning block, so as to ensure that the positioning block can maintain a stable shape and size during the long-term and high-intensity production process, thereby ensuring the quality and accuracy of the product.

[0032] See also Figure 2In a specific embodiment, the positioning mold 33 is first roughly aligned with the lower mold 32 or the upper mold 31 is roughly aligned with the mounting groove on the clamping block 25. After the mounting grooves are roughly aligned, the first positioning block 313 and the second positioning block 314 are respectively placed in the first positioning groove 311 and the second positioning groove 312. In the process of the first positioning block 313 and the second positioning block 314 being respectively placed in the first positioning groove 311 and the second positioning groove 312, the positions of the positioning mold 33 and the lower mold 32 and the upper mold 31 and the clamping block 25 are calibrated through the shape setting of the first positioning block 313 and the second positioning block 314, so that their positions are completely positioned. When the first positioning block 313 and the second positioning block 314 completely enter the first positioning groove 311 and the second positioning groove 312, the first positioning block 313 and the second positioning block 314 completely determine the relative positions of the positioning mold 33 and the lower mold 32 and the upper mold 31 and the clamping block 25, and through the shapes of the first positioning block 313 and the second positioning block 314, the relative positions of the positioning mold 33 and the lower mold 32 and the upper mold 31 and the clamping block 25 cannot be changed when the first positioning block 313 and the second positioning block 314 are not pulled out of the first positioning groove 311 and the second positioning groove 312.

[0033] See also Figure 2 or Figure 4 Preferably, the positioning groove is provided with a large end and a small end; the cross section of the small end is rectangular; the cross section of the large end is an isosceles trapezoid; the positioning grooves on the upper mold 31 and the lower mold 32 are set as the large end; the positioning grooves on the clamping block 25 and the positioning mold 33 are set as the small end; the positioning block is adaptively arranged to the shape of the positioning groove.

[0034] Through the above design, the cooperation between the large end and the small end of the positioning groove enables the positioning block to automatically adjust its position during the insertion process to achieve accurate calibration. At the same time, the isosceles trapezoidal design allows the positioning block to have a certain degree of guidance during insertion, making it easier to find the correct position. This design not only improves assembly efficiency, but also reduces assembly difficulty, making the use of the entire fixture more convenient.

[0035] In practical applications, the high-voltage connector processing fixture can achieve efficient and accurate processing of the high-voltage connector 12 by accurately positioning and pressing. At the same time, the fixture has a simple structure and is easy to operate, so that production personnel can easily get started and quickly master the use method. In addition, the interchangeability and versatility of the fixture also make it applicable to the processing requirements of high-voltage connectors 12 of different specifications, improving production efficiency and product quality.

[0036] See also Figure 2 and Figure 4The upper mold 31 and the clamping block 25 are connected after being positioned through the first positioning groove 311 and the first positioning block 313; the lower mold 32 and the positioning mold 33 are connected after being positioned through the second positioning groove 312 and the second positioning block 314; the upper mold 31 and the lower mold 32 are opened or closed by the connection between the clamping arm 22 and the clamping cylinder 21. The clamping cylinder 21 and the fixture are respectively arranged at both ends of the mounting plate 14; the first support seat 23 is arranged at the top of the piston rod 211 of the clamping cylinder 21; the second support seat 24 is arranged between the clamping cylinder 21 and the fixture; the first support seat 23 moves according to the lifting and lowering of the piston rod 211.

[0037] The clamping arm 22 is hinged with the first support seat 23 and the second support seat 24. When the piston rod 211 of the clamping cylinder 21 moves upward, one end of the clamping arm 22 is driven to move based on the first support seat 23, and then clamped based on the second support seat 24. The clamping block 25 is clamped by contact with the upper mold 31. Since the positioning mold 33 and the lower mold 32 are fixed by the bottom, when the upper mold 31 is pressed downward, the positioning groove is closed.

[0038] Example 2

[0039] See also Figure 1 The embodiment of the utility model provides a high-voltage joint processing jig; the jig is arranged on a working panel 11 on one side of the processing device; the processing device approaches or moves away from the jig through a displacement mechanism; the displacement mechanism includes a first displacement mechanism and a second displacement mechanism; the second displacement mechanism is arranged on one side of a top plate 41 arranged on the top of the first displacement mechanism; a joint mounting block 51 and an auxiliary mounting portion 52 are arranged on one side of the second displacement mechanism; a high-voltage joint 12 is arranged in the joint mounting block 51 and fixed; the joint mounting block 51 and the auxiliary mounting portion 52 are arranged adjacent to each other; the joint mounting block 51 and the auxiliary mounting portion 52 are both arranged on the second displacement mechanism through a connecting plate 53; the joint mounting block 51 and the auxiliary mounting portion 52 are arranged opposite to the processing end 152. The auxiliary mounting portion 52 is a hole expansion module; the joint mounting block 51 and the auxiliary mounting portion 52 are adaptively arranged with the jig.

[0040] See also Figure 1, the fixture is set on the working panel 11, and the processing device can flexibly approach or move away from the fixture through the displacement mechanism, realizing an efficient and accurate processing process. The displacement mechanism includes a first displacement mechanism and a second displacement mechanism. This design allows the processing device to move freely in two directions, further enhancing the flexibility and adaptability of the processing. In particular, the second displacement mechanism is arranged on one side of the top plate 41 set on the top of the first displacement mechanism. This layout is not only compact in structure, but also enables the processing device to more accurately locate the high-voltage connector 12. In the design of the connector mounting block 51 and the auxiliary mounting part 52, we adopted an adjacent setting method, which can ensure that the high-voltage connector 12 is stably supported and fixed during the processing. It can also make it possible to expand the hole and process without replacing the working parts separately, only changing the position. At the same time, the connector mounting block 51 and the auxiliary mounting part 52 are connected to the second displacement mechanism through the connecting plate 53. This connection method is both firm and easy to adjust, making the entire processing process smoother. The joint mounting block 51 and the auxiliary mounting portion 52 are arranged opposite to the processing end 152. This layout can ensure that the processing end 152 can accurately contact the high-voltage joint 12, thereby achieving precise processing. At the same time, this design also reduces errors and deviations during the processing, and improves product quality and processing efficiency.

[0041] See also Figure 1 or Figure 3 The first displacement mechanism and the second displacement mechanism are respectively provided with a first cylinder 54 and a second cylinder 55; the first cylinder 54 is provided at the bottom of the working panel 11 and connected to the top plate 41 through the middle plate 42. A guide plate 43 is provided at the bottom of the first displacement mechanism; a first guide rail 431 and a second guide rail 432 are provided on both sides of the guide plate 43; the top plate 41 is respectively connected to the first guide rail 431 and the second guide rail 432 through sliders 433 provided on both sides. The second displacement mechanism is connected to the slider 433 on the connecting plate 53 of the second displacement mechanism through a third guide rail provided on the side of the top plate 41.

[0042] Furthermore, the stroke and speed of the first cylinder 54 and the second cylinder 55 can be adjusted, and the joint mounting block 51 and the auxiliary mounting portion 52 can be adaptively replaced to adapt to high-pressure joints 12 and oil pipes 13 of different specifications and processing requirements. By adjusting the stroke of the cylinder, the moving distance of the processing device in the horizontal and vertical directions can be controlled to ensure processing accuracy and efficiency. In addition, the guide plate 43 provides stable support, while the first guide rail 431 and the second guide rail 432 ensure the smooth movement of the top plate 41 in the horizontal direction. The close fit between the slider 433 and the guide rail reduces friction and resistance, making the entire processing process smoother. The design of the third guide rail enables the second displacement mechanism to move flexibly in a direction perpendicular to the top plate 41, thereby realizing the processing of different parts of the high-pressure joint 12. The cooperation between the slider 433 on the connecting plate 53 and the third guide rail ensures the precise positioning and movement of the processing device in the vertical direction. By optimizing the design of the displacement mechanism and the cylinder, and strengthening the coordination between the guide rail and the slider 433, the high-pressure connector 12 processing fixture realizes a more efficient, accurate and flexible processing process. This design not only improves production efficiency, but also reduces production costs, providing a reliable solution for the processing of the high-pressure connector 12.

[0043] Example 3

[0044] See also Figure 1 The embodiment of the utility model provides a high-pressure joint processing jig and a processing device thereof; the working principle of the jig and the processing device thereof is to position and install the oil pipe 13 through the jig, and after the installation is completed, the clamping mechanism clamps the top of the upper mold 31 to stabilize the cooperation of the upper and lower molds 32, which is convenient for processing. The upper and lower molds 32 are also tightened so that they are not easy to separate after being joined. The processing device is provided with two moving mechanisms with different displacement directions, which are driven by a cylinder to make the two displacement mechanisms displaced, and the two different displacement mechanisms are controlled to move in different displacement directions so that they are away from or close to the position where the jig is set, and then the hole is expanded through the expansion module of the auxiliary installation part 52, and then the high-pressure joint 12 and the oil pipe 13 are installed, and then the high-pressure joint 12 is connected to the oil pipe 13. Generally, the oil pipe should be preheated before use to make it easier to expand the hole. According to the corresponding oil pipe joint installed on the product, put the end of the oil pipe where the joint needs to be installed into the preheating box for preheating, put the preheated oil pipe into the fixture, and complete the assembly of the oil pipe and the high-pressure joint 12 by manual operation.

[0045] This fixture is simple in design and easy to operate, allowing production personnel to quickly get started and easily master how to use it. This greatly reduces training costs and improves the flexibility of the production line. Secondly, the fixture is highly interchangeable and versatile, and can adapt to the processing requirements of high-pressure connectors 12 of different specifications, thereby reducing the time and cost of replacing the fixture and further improving production efficiency. The design of this high-pressure connector processing fixture not only improves processing efficiency, but also ensures processing accuracy and product quality. Its unique clamping mechanism and fixture structure make the clamping of the oil pipe 13 more stable, avoiding the offset and vibration generated during the processing process, thereby improving the accuracy and stability of the processing. In practical applications, this high-pressure connector processing fixture can effectively improve production efficiency and reduce production costs, while also reducing the labor intensity of workers and improving the comfort of the working environment.

[0046] See also Figure 1 The fixture is combined with the displacement mechanism of the processing device to achieve flexible movement and precise positioning of the processing device. The first displacement mechanism and the second displacement mechanism are driven by cylinders to accurately control the moving distance of the processing device in the horizontal and vertical directions, thereby ensuring processing accuracy and efficiency. At the same time, the cooperation between the guide rail and the slider 433 reduces friction and resistance, making the entire processing process more stable and reliable.

[0047] During the processing, the fixture can stably support and fix the high-pressure joint 12, ensuring that the processing end 152 can accurately contact the joint part. This not only improves the processing quality, but also reduces the risk of damage caused by improper operation. In addition, the setting of the auxiliary mounting part 52 allows the expansion and processing process to be carried out continuously without replacing the working parts, further improving the processing efficiency.
