[0064] Preferably, it also includes a placement slot (6), which is located above the other end of the mounting plate (13).

[0065] The working principle is as follows: When in use, the head section of a certain underwater vehicle is used as a part (7) for specific explanation. The head section of the vehicle is a frustum-shaped structure with a large diameter at one end and a small diameter at the other end.

[0066] In addition, the parts (7) that need to be tested in this utility model are mostly cylindrical power components on underwater vehicles.

[0067] When inspecting part (7), the operator first adjusts the hand crank (32) of the spacing adjustment component (3) according to the length of part (7). By turning the hand crank (32), the hand crank (32) drives the rotating screw (31) connected to it to rotate, thereby rotating the screw (31) to drive the connecting block (33) connected to it to move, thereby causing the slider (25) below the first moving seat (211) fixedly connected to the connecting block (33) to move along the guide plate (35). Finally, the distance between the first adjustment component (2) and the second adjustment component (4) is adjusted by the spacing adjustment component (3) so that the distance is slightly less than the length of part (7).

[0068] Then, the operator adjusts the distance between the two first moving support devices (21) by using the first adjustment handle (24) on the first adjustment assembly (2) so that the distance is adapted to support the part (7) at the small diameter end;

[0069] When adjusting the distance between the two first movable support devices (21), the operator rotates the first adjustment handle (24), which in turn drives the first adjustment rod (23) connected to it to rotate. This causes the first adjustment rod (23) to drive the two first movable support devices (21) connected to it to move, ultimately making the distance between the two first anti-slip sleeves (213) slightly smaller than the length of the part (7) at the small diameter end.

[0070] Next, the operator adjusts the distance between the two second moving support devices (41) by using the second adjustment handle (44) on the second adjustment assembly (4) so ​​that the distance is adapted to support the part (7) at the large diameter end;

[0071] When adjusting the distance between the two second movable support devices (41), the operator rotates the second adjustment handle (44), which in turn drives the second adjustment rod (43) connected to it to rotate. This causes the two second movable support devices (41) connected to it to move, ultimately making the distance between the two second anti-slip sleeves (413) slightly smaller than the length of the part (7) at the large diameter end.

[0072] Then, the staff used a hoisting device to hoist the part (7) above the first adjustment component (2) and the second adjustment component (4), so that the small diameter end of the part (7) was placed between the two first anti-slip sleeves (213) and the large diameter end of the part (7) was placed between the two second anti-slip sleeves (413).

[0073] Finally, the operator can rotate the part (7) by shaking the rotating handle (55) of at least one rotating adjustment component (5) to perform all-round inspection of the part (7), thereby improving inspection efficiency and ensuring part quality. After the part (7) to be inspected is completed, the hoisting device is used again to lift the inspected part (7) away. Then, the operator repeats the above operation steps to complete the inspection of other parts (7) until the inspection of all parts (7) to be inspected is completed.

[0074] In this invention, the parts (7) here are more often the hull, propeller shaft, pressure shell, detection equipment shell, sonar shell, float, such as submersible float, power battery tube, and propeller shell of an underwater vehicle.

[0075] After all parts (7) have been inspected, the operator only needs to move the utility model to the designated storage location for placement, so that it can be used for the next cycle.

[0076] The beneficial effects of this utility model compared with the prior art are:

[0077] 1. This utility model is ingeniously designed and simple to operate, ensuring that the parts remain in the correct position throughout the inspection process, thereby guaranteeing accurate measurement of their size and shape; at the same time, it enables efficient all-round inspection of the parts, thereby improving inspection efficiency and ensuring the quality of the parts.

[0078] 2. The first and second adjustment components of this utility model work together to adjust the diameter of the end face of the part so as to adapt and support the part, ensuring that the part is stably and uniformly supported, and improving the accuracy and efficiency of part processing and inspection.

[0079] 3. The first and second adjustment components of this utility model can adapt to the horizontal placement and inspection of parts of various shapes and sizes, and are not limited to a single specification. Especially in manufacturing and inspection environments with high precision requirements, this design can greatly improve the efficiency of the overall production line, reduce errors, reduce the frequency of tooling changes, and ultimately improve product quality and reduce costs.

[0080] 4. The spacing adjustment component (3) provided in this utility model can drive the first adjustment component (2) to move along the operating platform (1), thereby adjusting the spacing between the first adjustment component (2) and the second adjustment component (4) to meet the requirements of horizontal placement and testing of parts of different lengths;

[0081] 5. Because this utility model is equipped with two rotation adjustment components (5), the parts located above the two sets of first moving support devices (21) and second moving support devices (41) can be rotated by rotating the rotation adjustment components (5) to rotate the parts. The parts can be rotated to rotate the parts ...

[0082] 6. This utility model can balance detection accuracy, tooling cost and ease of operation to meet the needs of modern manufacturing for efficient and accurate detection, and can also be applied to various precision manufacturing and production processes;

[0083] 7. Both the first adjustment component (2) and the second adjustment component (4) of this utility model are provided with scales, which can be quickly adapted and adjusted according to the diameter of different end faces of the part (7) to achieve stable support;

[0084] 8. This utility model can also be applied to the assembly of certain irregularly shaped parts, and has a wide range of applications. Attached Figure Description

[0158] The outer wall of the first connector 51 is fixedly connected to the inner wall of the first connecting cylinder 212;

[0159] The second connector 52 has one end of its outer wall fixedly connected to the inner wall of the second connecting cylinder 412;

[0160] Guide latch rod 53, guide latch rod 53 is slidably latched into the first connector 51;

[0161] Universal coupling 54, one end of which is connected to guide snap rod 53, and the other end is connected to second connector 52;

[0162] Rotary handle 55 is connected to the non-universal coupling 54 end of guide rod 53.

[0163] In this utility model, a spline is provided on the outer surface of the guide latch rod 53. The spline works in conjunction with the first connector 51 to achieve reliable and efficient operation. The rotating handle 55 has a Z-shaped structure, and a protective sleeve is also provided on the rotating handle 55 with the Z-shaped structure.

[0164] Specifically, the protective sleeve is a rubber sleeve with several integrated rubber protective protrusions on its outer surface. These rubber protective protrusions are granular or annular. Therefore, since the protective sleeve is provided on the hand grip of the rotating handle 55, it can protect the operator's hands from wear and tear during long-term work, ensuring safety during use.

[0165] Specifically, as shown in Figure 10, the first connector 51 has an overall cylindrical structure with open ends and a hollow interior, and the interior of the first connector 51 has multiple snap-fit ​​grooves circumferentially opened.

[0166] The second connecting member 52 is a connecting post. One end of the connecting post is fixedly connected to the inner wall of the second connecting cylinder 412, and the other end is fixedly or detachably connected to the universal coupling 54.

[0167] The guide rod 53 is a columnar structure with several connecting strips circumferentially connected to its outer wall. One end of the guide rod 53 is fixedly connected to the universal coupling 54 or detachably connected.

[0168] The universal coupling 54 is connected to mounting sleeves at both ends, and the fixed end of the mounting sleeve has a locking connection hole.

[0169] In this utility model, the guide locking rod 53 is sleeved inside the first connecting member 51. Several connecting strips of the guide locking rod 53 are engaged with multiple locking grooves on the inner wall of the first connecting member 51. The guide locking rod 53 can move back and forth along the axial direction of the first connecting member 51, and can also drive the first connecting member 51 to rotate 360 ​​degrees in the circumferential direction.

[0170] In this utility model, the second connecting member 52 and the universal coupling 54 are connected by a through mounting hole; when the second connecting member 52 and the universal coupling 54 are fixedly connected, the second connecting member 52 is sleeved in the mounting sleeve of the universal coupling 54 and then welded together; when the second connecting member 52 and the universal coupling 54 are detachably connected, the second connecting member 52 is sleeved in the mounting sleeve of the universal coupling 54 and then connected together by a bolt assembly; the bolt assembly includes a bolt, a nut and a washer.

[0171] The guide rod 53 and the universal coupling 54 are connected by a locking mounting hole; when the guide rod 53 and the universal coupling 54 are fixedly connected, the guide rod 53 is sleeved in the mounting sleeve of the universal coupling 54 and then welded together; the guide rod 53 and the universal coupling 54 are detachable.

[0172] During connection, the guide snap rod 53 is sleeved inside the mounting sleeve of the universal coupling 54 and then connected together by bolt assembly.

[0173] Furthermore, as shown in Figure 4, the operating platform 1 described in the figure includes:

[0174] Support frame 12;

[0175] Mounting plate 13 is connected above support frame 12;

[0176] The sliding grooves 11 are respectively opened on one end of the mounting plate 13.

[0177] In this invention, the total number of sliding grooves 11 is three.

[0178] In the above embodiment 1, the head section of an underwater vehicle is used as part 7 for specific description. The head section of the vehicle is a frustum-shaped structure with a large diameter at one end and a small diameter at the other end.

[0179] In addition, the parts 7 that need to be tested in this invention are mostly cylindrical power components on underwater vehicles.

[0180] When inspecting part 7, the operator first adjusts the crank 32 of the spacing adjustment component 3 according to the length of part 7. By turning the crank 32, the crank 32 drives the rotating screw 31 connected to it to rotate, thereby rotating the screw 31 and driving the connecting block 33 threaded to it to move. This causes the slider 25 below the first moving seat 211 fixedly connected to the connecting block 33 to move along the guide plate 35. Finally, the distance between the first adjustment component 2 and the second adjustment component 4 is adjusted by the spacing adjustment component 3 so that the distance is slightly less than the length of part 7.

[0181] Then, the operator adjusts the distance between the two first movable support devices 21 by using the first adjustment handle 24 on the first adjustment assembly 2, so that the distance is adapted to support the part 7 at the small diameter end; when adjusting the distance between the two first movable support devices 21, the operator rotates the first adjustment handle 24, which in turn drives the first adjustment rod 23 connected to it to rotate, thereby the first adjustment rod 23 drives the two first movable support devices 21 threaded to it to move, so that the distance between the two first anti-slip sleeves 213 is slightly smaller than the length of the part 7 at the small diameter end;

[0182] Next, the operator adjusts the distance between the two second movable support devices 41 using the second adjustment handle 44 on the second adjustment assembly 4, so that the distance is adapted to support the large-diameter end of the part 7. When adjusting the distance between the two second movable support devices 41, the operator rotates the second adjustment handle 44, which in turn drives the second adjustment rod 43 connected to it to rotate. This causes the two second movable support devices 41 threadedly connected to it to move, ultimately making the gap between the two second anti-slip sleeves 413 slightly smaller than the length of the large-diameter end of the part 7.

[0183] Then, the workers used a hoisting device to hoist part 7 above the first adjusting component 2 and the second adjusting component 4, so that the small diameter end of part 7 is placed between the two first anti-slip sleeves 213 and the large diameter end of part 7 is placed between the two second anti-slip sleeves 413.

[0184] Finally, the operator can rotate the part 7 by cranking the rotating handle 55 of at least one rotating adjustment component 5 to perform a full-range inspection of the part 7, thereby improving inspection efficiency and ensuring part quality. After the part 7 that needs to be inspected is inspected, the hoisting device is used to lift the inspected part 7 away. Then, the operator repeats the above operation steps to complete the inspection of other parts 7 until all parts 7 that need to be inspected are inspected.

[0185] In this invention, part 7 here refers more to the hull, propeller shaft, pressure shell, detection equipment shell, sonar shell, float, such as submersible float, power battery tube, and propeller shell of an underwater vehicle.

[0186] After all parts 7 have been inspected, the operator only needs to move the utility model to the designated storage location for future use. Example

[0187] This embodiment 2 is the same as embodiment 1, except that a first scale 26 is provided on the outside of the two side plates of the first adjusting seat 22 along its length direction; and a second scale 45 is provided on the outside of the two side plates of the second adjusting seat 42 along its length direction.

[0188] In this embodiment 2, the adjustment sequence of the first adjustment component 2, the second adjustment component 4, and the spacing adjustment component 3 can be adjusted according to the convenience of the operator. Since the first adjustment component 2 is provided with a first scale 26 and the second adjustment component 4 is provided with a second scale 45, the operator can quickly adjust the specific distance to match the placement end of the part 7 according to the diameter of the placement position of the part 7. Since the first adjustment component 2 and the spacing adjustment component 3 are connected by a slider 25 and a guide plate 35, the stability of adjusting the first adjustment component 2 is further ensured, and the stability of placing the part 7 is also increased.

[0189] Other uses are the same as in Example 1, and will not be repeated here. Example

[0190] This embodiment 3 is the same as that of embodiments 1 and 2, except that it also includes a placement groove 6, which is located above the other end of the mounting plate 13.

[0191] The placement slot 6 is a grid-like arrangement, used to place small operating tools or small parts that need to be repaired during the inspection process.

[0192] Other uses are the same as in Example 1, and will not be repeated here.

[0193] Finally, it should be noted that the specific embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made to it.
