[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 In this embodiment of the present invention, a high-precision fastener multi-station synchronous processing fixture includes a bracket 1. The bracket 1 has a cuboid structure and an anti-slip pad on its bottom to increase friction with the placement surface and improve the overall stability of the device. A platform 2 is fixedly connected to the top of the bracket 1 by welding. The platform 2 has a rectangular flat structure. The bracket 1 provides a stable support foundation for the entire device, while the platform 2 serves to support the components above it. An L-shaped connecting plate 4 is bolted to the center of the front end of the frame 2. The L-shaped connecting plate 4 consists of a horizontal plate and a vertical plate, which are welded together at a 90-degree angle. The bottom vertical plate of the L-shaped connecting plate 4 is welded to a base plate 5. The base plate 5 has a rectangular structure. The L-shaped connecting plate 4 is used to connect the frame 2 and the base plate 5, so that the two form a stable right-angle connection structure. The base plate 5 provides a flat platform for the installation of subsequent components. Please see Figures 1-3 The upper surface of the base plate 5 is fixedly connected to the base plate body 14 by bolts. The size of the base plate body 14 is smaller than that of the base plate 5. The top of the base plate body 14 is fixedly connected to the clamp 7 by welding. The clamp 7 has a U-shaped structure. The base plate body 14 stably installs the clamp 7 on the base plate 5. The clamp 7 is one of the key components for realizing object clamping. A groove 8 is formed on the inner wall of the clamp 7. The groove 8 is elongated and its length matches the length of the inner wall of the clamp 7. A slider 9 is slidably connected to the opening of the groove 8. The shape of the slider 9 matches the shape of the groove 8, allowing it to slide smoothly within the groove 8. A displacement block 10 is welded and fixedly connected to the side of the slider 9 away from the groove 8. The displacement block 10 has a cuboid structure. The groove 8 provides a track for the slider 9 to slide. The sliding of the slider 9 within the groove 8 can drive the displacement block 10 to adjust its horizontal position. Please see Figures 1-3The end of the displacement block 10 away from the slider 9 is fixedly connected to a recess 13 by welding. The recess 13 has a U-shaped structure, and its opening faces away from the displacement block 10. A threaded hole is opened on the outer wall of the recess 13, and a bolt 11 is installed in the threaded hole. One end of the bolt 11 penetrates the outer wall of the recess 13 and is mounted with a connecting part 12 through a bearing. The connecting part 12 can move along the opening direction of the recess 13 under the drive of the bolt 11. The movement of the displacement block 10 will drive the recess 13 to move synchronously. By rotating the bolt 11, the position of the connecting part 12 on the recess 13 can be adjusted. A connecting rod 15 is fixedly connected to the end of the mating part 12 away from the recess 13 by welding. The connecting rod 15 has a cylindrical structure. A mating post 17 is fixedly connected to the end of the connecting rod 15 away from the mating part 12 by welding. The mating post 17 also has a cylindrical structure, but its diameter is larger than that of the connecting rod 15. The position change of the mating part 12 is transmitted to the mating post 17 through the connecting rod 15, so that the mating post 17 changes its position accordingly.

[0019] Please see Figures 1-3 Both ends of the docking column 17 are fixedly connected to side plates 18 by welding. The side plates 18 are rectangular sheet structures. An L-shaped connecting plate 4 is provided at the front end of the side plate 18. The L-shaped connecting plate 4 has the same structure as the L-shaped connecting plate 4 connected to the front end of the frame 2. A rotating shaft 16 is installed at the connection part between the L-shaped connecting plate 4 and the side plate 18. The rotating shaft 16 passes through the L-shaped connecting plate 4 and the side plate 18, allowing the side plate 18 to rotate freely around the rotating shaft 16. The movement of the docking column 17 will drive the side plate 18 to move, and the rotating shaft 16 allows the side plate 18 to rotate around the L-shaped connecting plate 4, increasing the adjustment range of the device. The end of the side piece 18 away from the L-shaped connecting plate 4 is fixedly connected to the pressure member 3 by welding. The pressure member 3 is curved, and its curvature can be designed according to the shape of common objects. For example, it can be designed to adapt to the arc shape of cylindrical objects. The rotation or movement of the side piece 18 will drive the pressure member 3 to move. The curved pressure member 3 can better fit the surface of the object and improve the stability of clamping. Please see Figures 1-3 The groove 8 is provided with a fastener 6. The fastener 6 can be a wing bolt. The fastener 6 is adapted to the height of the groove 8. One end of the fastener 6 passes through the side wall of the clamp 7 and extends into the groove 8, and can abut against the slider 9. When the slider 9 is adjusted to a suitable position in the groove 8, the slider 9 can be fixed in the groove 8 by tightening the fastener 6 to prevent it from shifting during operation.

[0020] The working principle of this utility model is as follows: First, loosen the fastener 6 so that it no longer exerts pressure on the slider 9, and push the slider 9 to slide in the groove 8. The slider 9 drives a series of components such as the displacement block 10 and the concave block 13 to move, and initially adjust the position of the pressure piece 3 so that the pressure piece 3 is roughly above the cylindrical metal shaft. Next, rotate bolt 11 to adjust the extension length of mating part 12 on recess 13, and further precisely adjust the position of pressure part 3 so that the curved surface of pressure part 3 can roughly fit the surface of the part. During the adjustment process, the side piece 18 will rotate around the rotating shaft 16, so that the angle of the pressure piece 3 adapts to the shape of the cylindrical metal shaft, ensuring that the pressure piece 3 can make close contact with the surface of the shaft. After the clamping part 3 is adjusted to the appropriate clamping position and angle, tighten the fastener 6 to fix the slider 9 in the groove 8, and at the same time ensure that the bolt 11 is in a tightened state. At this time, the cylindrical metal shaft is stably clamped and subsequent processing operations can be carried out. The bending radius of its pressure component 3 has been adjusted according to the shape of common square parts. The material is high-strength engineering plastic, which has a certain degree of elasticity and is suitable for fixing small plastic parts, thus avoiding damage to the surface of the plastic parts. Loosen fastener 6 and push slider 9 to slide within groove 8, causing related components to move and move pressure piece 3 above the square plastic block. Rotate bolt 11 and adjust the position of mating piece 12, allowing pressure piece 3 to gradually approach the surface of the square plastic block. Because pressure piece 3 is made of high-strength engineering plastic, it has a certain degree of elasticity and can undergo slight deformation when in contact with the square plastic block, thus better conforming to the square surface.

[0021] Side plate 18 rotates around shaft 16 to match the angle of pressure piece 3 with the side of square plastic block. After adjustment, tighten fastener 6 and bolt 11 to achieve stable fixation of square plastic block, which can then be used for subsequent testing or assembly.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
