[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This application provides a positioning worktable that can provide dedicated positioning assembly for assembling sealing rings.

[0025] See Figures 1 to 2As shown in the figure, this application embodiment provides a positioning worktable, including a base plate 1, fixing blocks 2, and an adjustment assembly. The base plate 1 is rectangular and has threaded holes, which facilitate the installation of the base plate 1 at any workstation using threaded connectors. Therefore, the positioning worktable provided in this application also includes a mounting table 8, on which the base plate 1 is fixed for easy operation by the operator. Further, two fixing blocks 2 are symmetrically arranged along the base plate 1, and abutment grooves 3 are provided on opposite sides of the two fixing blocks 2. Since a cavity for placing a sealing ring 4 is formed between the two fixing blocks 2, the inner wall of the abutment groove 3 can be tangent to the sealing ring 4. The adjustment assembly is connected to the fixing blocks 2 and is used to drive the fixing blocks 2 to move, thereby effectively positioning and clamping the sealing ring 4 between the two fixing blocks 2. This makes it easy to determine the center of the sealing ring 4, allowing for quick alignment of the axis when assembling the sealing ring 4 with other components, improving assembly efficiency and accuracy, and facilitating operation. This application primarily focuses on the bonding and positioning of the sealing ring 4 to the PTFE membrane. The bonding of the sealing ring 4 to the PTFE membrane and subsequent secondary vulcanization significantly improves the sealing performance, durability, and adaptability to complex working conditions of the sealing ring 4. Simultaneously, secondary vulcanization also improves the mechanical properties of the sealing ring 4, enhances its thermal stability, reduces gas generation, and shortens the production cycle. These benefits enable the widespread application of this composite structure sealing ring 4 in various fields.

[0026] In this application, the adjustment component includes a baffle 5 and an adjustment bolt 6. The baffle 5 is fixed on the base plate 1 and located on one side of the fixing block 2. The baffle 5 is rectangular and fits the width direction of the base plate 1. The adjustment bolt 6 passes through the baffle 5 and is threadedly engaged with the baffle 5. In addition, a limiting groove 60 is provided on the fixing block 2, and the end of the adjustment bolt 6 abuts against the limiting groove 60.

[0027] Therefore, during use, by rotating the adjusting bolt 6, the end of the adjusting bolt 6 abuts against the limiting groove 60. Then, as the adjusting bolt 6 rotates and shifts, it effectively pushes the fixing block 2 to move along the length of the base plate 1 until the inner wall of the abutment groove 3 is tangentially aligned with the sealing ring 4. Immediately stop driving the adjusting bolt 6. In this application, the knob of the adjusting bolt 6 can be implemented by installing a handle on the adjusting bolt 6, resulting in a simple structure and convenient operation. Furthermore, the tangential alignment of the sealing ring 4 with the abutment groove 3 ensures effective positioning of the sealing ring 4 and reduces the possibility of compression deformation of the sealing ring 4.

[0028] In this application, the adjustment assembly further includes a push block 61, which is connected to the end of the adjustment bolt 6 and is also connected within the limiting groove 60. Thus, when the adjustment bolt 6 rotates, the push block 61 pushes against the fixed block 2 to move, thereby reducing wear on the adjustment bolt 6 and increasing its service life.

[0029] In addition, the width of the connection between the push block 61 and the adjusting bolt 6 is greater than the diameter of the adjusting bolt 6. The fixing block 2 is provided with an adjusting groove 62 that communicates with the limiting groove 60, and the adjusting bolt 6 extends into the connecting groove. This effectively restricts the push block 61 within the limiting groove 60, and the adjusting bolt 6 within the adjusting groove 62, preventing the push block 61 from falling out of the limiting groove 60 during use, thus ensuring a reliable structure.

[0030] In this application, a limiting component is also provided on the base plate 1 between the two fixed blocks 2. The limiting component is used to limit the contact between the two fixed blocks 2, effectively preventing the fixed blocks 2 from moving excessively and causing the sealing ring 4 to be squeezed and deformed. The limiting component includes a slider 70 and a locking member. The slider 70 is located between the two fixed blocks 2 and is movable on the base plate 1. The locking member is connected to the base plate 1 and is used to lock the slider 70.

[0031] In use, first adjust the position of slider 70 according to the size of sealing ring 4 so that slider 70 is aligned with the axis of sealing ring 4. Then, the locking device can fix slider 70. When the fixing block 2 moves close to slider 70, it is restricted by slider 70 and cannot move further, thus effectively limiting the fixing block 2 and ensuring that the fixing block 2 will not squeeze the sealing ring 4 during use.

[0032] In this application, the locking component includes a fixing bolt 71, which is connected to the side wall of the base plate 1. A pressure ring 72 is provided at one end of the slider 70. The head of the fixing bolt 71 is located in the middle of the pressure ring 72, thereby limiting the movement of the slider 70. The fixing bolt 71 also plays a certain limiting role, restricting the range of movement of the slider 70, making it convenient to use. The head of the fixing bolt 71 is used to abut against the end face of the pressure ring 72, thereby preventing the slider 70 from falling off the base plate 1, ensuring the slider 70 is easy to use and avoiding loss or missing parts. When the fixing bolt 71 is tightened, it effectively locks the slider 70. The fixing bolt 71 is directly pressed against the top of the pressure ring 72 and at least at the opposite sides, making the structure reliable.

[0033] In this application, the abutment groove 3 has at least one inner wall tangent to the sealing ring 4, and the two abutment grooves 3 are arranged parallel to each other on their inner walls tangent to the sealing ring 4. Therefore, in use, the two relatively parallel inner walls of the two abutment grooves 3 are sufficient to meet the usage requirements, resulting in a simple structure. In this application, the abutment groove 3 is V-shaped, which is simple in structure, and both side walls of the abutment groove 3 can tangentially contact the sealing ring 4. The opposing inner walls of the abutment grooves 3 on the two fixing blocks 2 also effectively maintain a parallel state. In other embodiments, the abutment groove 3 can also be a trapezoidal shape (with a bottom wall narrower than the opening) or an arc shape, including but not limited to.

[0034] In addition, to improve ease of operation, one of the two fixed blocks 2 is fixedly connected to the base plate 1, and the adjusting component is connected to the other fixed block 2 for adjusting its movement. During use, the sealing ring 4 is first brought into tangential contact with the abutment groove 3 on the fixed block 2 to achieve pre-positioning of the sealing ring 4. Then, the slider 70 is aligned with the axis of the sealing ring 4. Finally, the adjusting bolt 6 is rotated, causing the push block 61 to push against the inner wall of the limiting groove 60, effectively pushing the fixed block 2 until the inner wall of the abutment groove 3 contacts and is tangential to the sealing ring 4. During the movement of the fixed block 2, it is restricted by the slider 70, effectively preventing the fixed block 2 from squeezing and deforming the sealing ring 4. The overall operation is convenient, the structure is reliable, and the positioning is accurate.
