Description

Technical Field

[0001] This utility model relates to the field of flange processing equipment technology, and in particular to a quick clamping fixture for flange inspection. Background Technology

[0002] Flanges are key components in pipeline connections, and the flatness of their sealing surface and the accuracy of bolt hole distribution directly affect the reliability of the seal.

[0003] Traditional inspection methods, which use bolts to fix the flange, have the following drawbacks:

[0004] Low clamping efficiency: Each bolt needs to be tightened individually, which takes a long time (clamping a single piece takes ≥5 minutes);

[0005] Poor repeatability: Inconsistent manual pre-tightening force leads to slight deformation of the flange, affecting the accuracy of the inspection;

[0006] Insufficient versatility: Different flange specifications require customized tooling, resulting in high costs. Utility Model Content

[0007] To improve the problems of poor repeatability and lack of versatility in flange fixing methods and to increase the clamping efficiency of flanges, this application provides a quick clamping fixture for flange inspection.

[0008] The quick-clamping tooling for flange inspection provided in this application adopts the following technical solution:

[0009] A quick-clamping fixture for flange inspection includes a worktable with an inspection table at its center. Movable seats are slidably mounted on the worktable, with one movable seat on each opposite side. A drive assembly is provided on the worktable to move the two movable seats closer together or further apart. Clamping blocks are mounted on the movable seats and located on the opposite sidewalls of the two movable seats. An elastic buffer assembly is provided between the movable seats and the clamping blocks. V-grooves are formed on the clamping blocks and located on the opposite sidewalls of the two clamping blocks.

[0010] Preferably, the workbench is connected to a guide rail, which is arranged along the length of the workbench. There is one guide rail on each of the opposite sides of the testing table. A slider is slidably arranged on the guide rail. There is one slider at each end of each guide rail. A connecting plate is connected between the corresponding sliders on two guide rails. The movable seat is connected to the connecting plate.

[0011] Preferably, the guide rail has an "I" shaped cross-section, and the slider is adapted to the guide rail.

[0012] Preferably, the drive assembly includes a fixed bearing, a bidirectional threaded rod, a nut seat, and a drive motor. The worktable has a mounting groove along its length. The fixed bearing is connected to the mounting groove, with one fixed bearing at each end of the groove. The bidirectional threaded rod is connected between the two fixed bearings. The testing platform has a through hole for the bidirectional threaded rod to pass through. The drive motor is mounted on the worktable, and its output shaft is coaxially connected to the bidirectional threaded rod via a coupling. The nut seat is connected to the bidirectional threaded rod, with one nut seat symmetrically located at each end of the rod. The nut seat is connected to a movable seat.

[0013] Preferably, the elastic buffer assembly includes a guide rod, a buffer spring, and a limiting block. The guide rod is connected to the clamping block and is located on the side wall of the clamping block facing away from the V-groove. The guide rod is arranged in a direction perpendicular to the clamping block. The guide rod has one end at each end of its side wall. The movable seat has a connecting hole for the guide rod to pass through. The limiting block is connected to the end of the guide rod that passes through the movable seat. The buffer spring is sleeved on the outside of the guide rod, with one end of the buffer spring abutting against the clamping block and the other end abutting against the movable seat.

[0014] Preferably, a linear bearing is connected to the movable seat, the linear bearing is located in the connecting hole, and the guide rod passes through the linear bearing.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] This utility model provides a quick clamping fixture for flange inspection. Through a drive assembly, the movable seats on both sides and the clamping blocks can move equidistantly towards or away from each other. Combined with a V-groove design, the two clamping blocks can clamp and fix the flange, automatically and accurately aligning the flange to the center of the inspection table. This eliminates the problem of slight deformation and eccentricity of the flange caused by inconsistent manual pre-tightening force, providing a highly repeatable positioning reference for inspections (such as flatness and hole position), improving the reliability of inspection results. Furthermore, the two inclined surfaces of the V-groove can adaptively contact the outer circle of flanges with different diameters, allowing a single fixture to be compatible with clamping flanges of various specifications within a certain size range. This eliminates the need for frequent changes to customized fixtures, reducing equipment costs, increasing fixture utilization, and adapting to the needs of small-batch, multi-variety inspections. The elastic buffer assembly provides flexible clamping force, avoiding rigid impact damage to the flange sidewalls. Therefore, it improves the problems of poor repeatability and insufficient versatility in flange fixing methods, thereby increasing the efficiency of flange clamping. Attached Figure Description

[0022] This application discloses a quick-clamping fixture for flange inspection. (Refer to...) Figure 1 and Figure 2The quick clamping fixture for flange inspection includes a worktable 1, on which an inspection table 11 is provided. The inspection table 11 is located at the center of the worktable 1. Movable seats 2 are slidably arranged on the worktable 1. There is one movable seat 2 on each of the opposite sides of the worktable 1. The worktable 1 is provided with a drive assembly 3 for driving the two movable seats 2 to move closer or further apart. Clamping blocks 4 are provided on the movable seats 2. The clamping blocks 4 are located on the opposite side walls of the two movable seats 2. An elastic buffer assembly 5 is provided between the movable seats 2 and the clamping blocks 4. V-grooves 41 are opened on the clamping blocks 4. The V-grooves 41 are located on the opposite side walls of the two clamping blocks 4.

[0023] The drive assembly 3 can synchronously drive the movable seats 2 on both sides and the clamping blocks 4 to move equidistantly towards or away from each other. Combined with the V-groove 41 design, the two clamping blocks 4 can clamp and fix the flange, so that the flange is automatically and accurately aligned with the center of the inspection table 11. This eliminates the problem of slight deformation and eccentricity of the flange caused by inconsistent manual pre-tightening force, and provides a highly repeatable positioning reference for inspection (such as flatness and hole position), improving the reliability of inspection results. In addition, the two inclined surfaces of the V-groove 41 can adaptively contact the outer circle of flanges with different diameters, so that a single tooling can be compatible with clamping flanges of various specifications within a certain size range. This eliminates the need for frequent replacement of customized tooling, reduces equipment costs, improves tooling utilization, and adapts to the needs of small batch and multi-variety inspection. The elastic buffer assembly 5 provides flexible clamping force to avoid rigid impact damage to the flange sidewall.

[0024] A guide rail 12 is connected to the workbench 1. The guide rail 12 is set along the length of the workbench 1. There is one guide rail 12 on each side of the detection table 11. A slider 121 is slidably set on the guide rail 12. There is one slider 121 at each end of each guide rail 12. A connecting plate 1211 is connected between the corresponding sliders 121 on the two guide rails 12. The movable seat 2 is connected to the connecting plate 1211. The cross section of the guide rail 12 is set in the shape of "I". The slider 121 is adapted to the guide rail 12.

[0025] The combination of the "I"-shaped guide rail 12 and the matching slider 121, as well as the rigid connection between the movable seat 2 and the sliders 121 on both sides through the connecting plate 1211, constitutes a high-rigidity guide support system. This ensures that the movable seat 2 and the clamping block 4 slide smoothly, steadily, and with low friction along the set trajectory, without shaking or jamming. This provides a solid mechanical foundation for precise automatic centering and stable clamping, reducing motion errors.

[0026] The drive assembly 3 includes a fixed bearing 31, a bidirectional threaded rod 32, a nut seat 33, and a drive motor 34. A mounting slot is provided on the worktable 1 along its length. The fixed bearing 31 is connected to the mounting slot, with one fixed bearing 31 at each end of the slot. The bidirectional threaded rod 32 is connected between the two fixed bearings 31. A through hole is provided on the testing table 11 for the bidirectional threaded rod 32 to pass through. The drive motor 34 is mounted on the worktable 1. The output shaft of the drive motor 34 is coaxially connected to the bidirectional threaded rod 32 via a coupling. The nut seat 33 is connected to the bidirectional threaded rod 32, with one nut seat 33 symmetrically located at each end of the bidirectional threaded rod 32. The nut seat 33 is connected to the movable seat 2.

[0027] The elastic buffer assembly 5 includes a guide rod 51, a buffer spring 52, and a limiting block 53. The guide rod 51 is connected to the clamping block 4 and is located on the side wall of the clamping block 4 facing away from the V-groove 41. The guide rod 51 is arranged in a direction perpendicular to the clamping block 4. The guide rod 51 has one at each end of its side wall. The movable seat 2 has a connecting hole for the guide rod 51 to pass through. The limiting block 53 is connected to the end of the guide rod 51 that passes through the movable seat 2. The buffer spring 52 is sleeved on the outside of the guide rod 51. One end of the buffer spring 52 abuts against the clamping block 4, and the other end abuts against the movable seat 2.

[0028] When the clamping block 4 contacts the flange, the buffer spring 52 is compressed, and the resulting elastic force buffers the impact force, avoiding rigid impact damage to the flange surface (especially the precision-machined sealing surface).

[0029] A linear bearing 21 is connected to the movable seat 2. The linear bearing 21 is located in the connecting hole. The guide rod 51 passes through the linear bearing 21. The linear bearing 21 further reduces the frictional resistance of the guide rod 51, improves the response sensitivity of the buffer assembly, and extends the life of the guide rod 51.

[0030] The implementation principle of a quick clamping fixture for flange inspection according to an embodiment of this application is as follows: When clamping the flange, the flange is placed on the inspection table 11 and roughly positioned at the center of the inspection table 11 by visual inspection. Then, the drive motor 34 drives the bidirectional threaded rod 32 to rotate. The two nut seats 33 can move closer to each other under the combined action of the guide rail 12, the slider 121 and the connecting plate 1211, which drives the corresponding movable seat 2 and the clamping block 4 to move closer, so that the V-groove 41 of the clamping block 4 clamps the flange sidewall. With the cooperation of the flange's circular sidewall, the flange can be quickly centered at the center of the inspection table 11.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
