While these methods can meet basic processing requirements, they are mostly designed for regular workpieces such as shafts and plates, and cannot effectively fit the irregular curved surfaces of shackles. They also cannot meet the requirements of high precision and strong clamping force, thus reducing the processing accuracy of anchor chain shackles and consequently hindering their assembly efficiency.

[0005] To address this issue, a positioning mechanism for anchor chain connection shackle processing is proposed to improve existing problems. Utility Model Content

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] Please see Figures 1-7 The present invention provides the following technical solution:

[0031] Example 1, see Figures 1-7A positioning mechanism for processing anchor chain connection shackles includes a processing machine tool 1. A drilling mechanism 2 is symmetrically arranged on the top of the processing machine tool 1 in the axial direction. A support frame 3 is arranged between the drilling mechanisms 2. An adaptive positioning mechanism 4 is also symmetrically arranged on both sides of the support frame 3 in the axial direction.

[0032] The drilling mechanism 2 includes a drive cylinder 21, a drive plate 22 disposed at the extension end of the drive cylinder 21, a support base 23 disposed at the top of the drive plate 22, a support column 24 disposed above the support base 23, a drive motor 25 disposed at one end of the support column 24, a spindle 26 disposed at the output end of the drive motor 25, and a drill bit 27 disposed at the end of the spindle 26 away from the drive motor 25.

[0033] Before drilling holes in the anchor chain shackle, the anchor chain shackle can be placed on the support frame 3, so that both ends of the anchor chain shackle are located in the corresponding adaptive positioning mechanism 4. Then, the adaptive positioning mechanism 4 is activated to tightly clamp the irregular curved surfaces of the outer walls of both ends of the anchor chain shackle. This avoids the problem in the traditional anchor chain shackle processing process, which generally relies on manual positioning or simple mechanical fixtures for fixing. Although it can meet basic processing requirements, its design is mostly for regular workpieces such as shafts and plates, and cannot effectively fit the irregular curved surfaces of the shackle. This improves the clamping force on the irregular curved surfaces of the anchor chain shackle, thereby improving the processing accuracy.

[0034] When drilling holes in the anchor chain shackle, the drive cylinder 21 is activated, and its telescopic end pushes the drive plate 22 to move, causing the support base 23, support column 24, drive motor 25, spindle 26 and drill bit 27 to move synchronously, so that the drill bit 27 moves closer to the end of the anchor chain shackle. Then, the drive motor 25 is activated, and the spindle 26 drives the drill bit 27 to rotate, so that the drill bit 27 can drill holes in the end of the anchor chain shackle.

[0035] See Figures 1-7 Furthermore, the top of the support base 23 is provided with a support hole 231, and the bottom of the support column 24 can be inserted into the support hole 231; the output end of the drive motor 25 passes through the side wall of the support column 24 and is connected to the end of the spindle 26 away from the drill bit 27, and the spindle 26 is located inside the support column 24.

[0036] The design of the support hole 231 allows the support column 24 to be inserted into the support hole 231, thereby providing support. The support height of the support column 24 can also be adjusted. After the height is adjusted, it can be fixed and locked with bolts.

[0037] See Figures 1-7Furthermore, the bottom of the support base 23 is symmetrically provided with sliders 28 in the radial direction, and a slide rail 29 is provided below the sliders 28. The sliders 28 can slide on the corresponding slide rail 29, and the slide rail 29 is located on the top of the processing machine tool 1.

[0038] When the drive cylinder 21 is activated, its telescopic end pushes the drive plate 22 to move, thereby enabling the drive plate 22 to drive the corresponding slider 28 to slide on the corresponding slide rail 29, thus achieving the purpose of guidance.

[0039] One end of the support frame 3 is located on the top of the machine tool 1, and the other end is arc-shaped. The arc-shaped end of the support frame 3 is used to support the anchor chain shackle.

[0040] See Figures 1-7 Furthermore, the adaptive positioning mechanism 4 includes a support 41, a positioning cylinder 42 disposed at one end of the support 41, a positioning plate 43 disposed at the telescopic end of the positioning cylinder 42, and an adaptive component 44 symmetrically disposed in the radial direction at the end of the positioning plate 43 away from the positioning cylinder 42.

[0041] When it is necessary to clamp the irregular curved surface of the anchor chain shackle, the positioning cylinder 42 is activated. Its telescopic end pushes the positioning plate 43 to move, thereby allowing the adaptive component 44 connected to the positioning plate 43 to approach the irregular curved surface of the anchor chain shackle. This pushes the irregular curved surface of the anchor chain shackle to fit tightly against the fixed adaptive component 44, thus clamping the irregular curved surface of the anchor chain shackle with the two adaptive components 44. This achieves the purpose of tightly clamping the irregular curved surface of the anchor chain shackle with the two adaptive components 44, avoiding the problem in traditional anchor chain shackle processing technology that generally relies on manual positioning or simple mechanical fixtures for fixing. Although these can meet basic processing requirements, their design is mostly for regular workpieces such as shafts and plates, and cannot effectively fit the irregular curved surface of the shackle. This improves the clamping force on the irregular curved surface of the anchor chain shackle, thereby improving the processing accuracy.

[0042] See Figures 1-7 Furthermore, the side of the support seat 41 is concave, and a guide groove 411 is provided at the top of the concave surface of the support seat 41. A guide block 431 is provided at the bottom of the positioning plate 43. The guide block 431 can slide in the guide groove 411. The telescopic end of the positioning cylinder 42 passes through the side wall of the support seat 41 and is connected to the positioning plate 43. One adaptive component 44 is located in the support seat 41, and the other adaptive component 44 is connected to the side of the positioning plate 43 away from the positioning cylinder 42.

[0043] During the displacement of the positioning plate 43, the guide block 431 will also slide within the guide groove 411, thereby achieving the purpose of guidance.

[0044] See Figures 1-7Furthermore, the adaptive component 44 includes a positioning seat 441 and positioning rods 442 evenly arranged on one side of the positioning seat 441. One end of the positioning rod 442 is provided with a spring 443. Positioning holes 444 are also evenly opened on the side wall of the positioning seat 441. The positioning rods 442 and springs 443 are both located in the corresponding positioning holes 444. The end of the spring 443 away from the positioning rod 442 is connected to the inner wall of the positioning hole 444, and the end of the positioning rod 442 away from the spring 443 extends out of the positioning hole 444.

[0045] In the process of clamping the irregular curved surface of the anchor chain shackle by the two adaptive components 44, the positioning rod 442 will retract into the corresponding positioning rod 442 after being subjected to compressive force, causing the corresponding spring 443 to deform from a free state to a compressed state; thereby achieving the purpose of tightly fitting and clamping the irregular curved surface of the anchor chain shackle; avoiding the problem in the traditional anchor chain shackle processing process that generally relies on manual positioning or simple mechanical fixtures for fixing, although it can meet basic processing requirements, its design is mostly for regular workpieces such as shafts and plates, and cannot effectively fit the irregular curved surface of the shackle, thereby improving the clamping force on the irregular curved surface of the anchor chain shackle, and thus improving the processing accuracy.

[0046] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
