The anchor chain shackle includes a "U"-shaped buckle and a cross pin. The two ends of the "U"-shaped buckle are respectively provided with pin holes, and the cross pin is inserted into the pin holes. When using, first take out the cross pin of the anchor chain shackle, put the "U"-shaped buckle into the anchor chain ring to be connected, and then connect the cross pin to the anchor chain ring above.

[0007] By adopting the above technical scheme, when the driving component drives the upper clamping plate to rotate toward the lower clamping plate to the extreme position, the upper clamping plate and the lower clamping plate clamp the "U"-shaped buckle to reduce the possibility of the "U"-shaped buckle moving during processing; the driving device drives the two sets of tool holders to move toward the lower clamping plate to process the pin holes of the clamped "U"-shaped buckle, and the tool holders on both sides move synchronously to process the pin holes at both ends of the "U"-shaped buckle at the same time, so as to improve the processing efficiency of the anchor chain shackle pin hole and reduce the possibility that the coaxiality of the two pin holes is difficult to ensure.

[0014] Preferably, a second avoidance groove is provided on the matching block, and the second avoidance groove is coaxial with the lower avoidance groove.
[0015] By adopting the above technical solution, the second avoidance groove is used to avoid the drill bit, thereby reducing the possibility of the drill bit hitting the lower abutment plate.

[0017] By adopting the above technical solution, the first motor drives the gear to rotate, and through the meshing connection between the gear and the arc-shaped rack, the arc-shaped rack moves around the rotation axis direction of the upper pressure plate, thereby rotating the upper pressure plate.
[0018] Preferably, the driving device includes a screw and a second motor, the screw is connected to the workbench and rotates along the sliding direction of the tool holder, the two ends of the screw are respectively passed through and threadedly connected to the two groups of tool holders, the threads at the two ends of the screw have opposite rotation directions, and the second motor is fixedly connected to the workbench, and the second motor is used to drive the rotation of the screw.
[0019] By adopting the above technical solution, the second motor drives the lead screw to rotate, and through the threaded connection between the lead screw and the two sets of tool holders, the two sets of tool holders move along the axial direction of the lead screw. Since the threads at both ends of the lead screw have opposite rotation directions, the two sets of tool holders move in opposite directions, so that the two sets of tool holders can perform pin hole forming operations on the clamped "U"-shaped block from both sides at the same time.

[0032] The embodiment of the present application discloses a device for processing a pin hole of an anchor chain shackle for a ship.
[0033] Reference Figure 1-Figure 6, a device for processing a pin hole of a ship anchor chain shackle of the present embodiment comprises a workbench 1, on which a clamping mechanism 2 for clamping a "U"-shaped buckle and a drilling mechanism 3 for forming a pin hole are installed, the clamping mechanism comprises an upper clamping plate 21, a lower clamping plate 22 and a driving assembly 23, the lower clamping plate 22 is fixedly connected to the workbench 1, the upper clamping plate 21 is rotatably connected to the lower clamping plate 22, the driving assembly 23 is used to drive the rotation of the upper clamping plate 21, the drilling mechanism 3 comprises two sets of tool holders 31 for installing a drill bit 311 and a driving device 32, the two sets of tool holders 31 are respectively slidably connected to the workbench 1, the two sets of tool holders 31 are respectively fixedly connected to the third motor 312, the third motor 312 is used to drive the rotation of the drill bit 311, the sliding directions of the two sets of tool holders 31 are opposite, and the driving device 32 drives the two sets of tool holders 31 to move synchronously.
[0034] Reference Figure 1-Figure 5 When the driving assembly 23 drives the upper clamping plate 21 to rotate toward the lower clamping plate 22 to the extreme position, the upper clamping plate 21 and the lower clamping plate 22 clamp the "U"-shaped buckle to reduce the possibility of the "U"-shaped buckle moving during processing; the driving device 32 drives the two sets of tool holders 31 to move toward the side of the lower clamping plate 22 respectively, and processes the pin holes of the clamped "U"-shaped buckle. The tool holders 31 on both sides move synchronously and process the pin holes at both ends of the "U"-shaped buckle at the same time, so as to improve the processing efficiency of the pin holes of the anchor chain shackle 4 and reduce the possibility that the coaxiality of the two pin holes is difficult to ensure.
[0035] Reference Figure 1-Figure 4 The upper clamping plate 21 is provided with an upper abutting groove 211, and the lower clamping plate 22 is provided with a lower abutting groove 221. When the driving assembly 23 drives the upper clamping plate 21 to rotate toward the side of the lower clamping plate 22 to abut against the lower clamping plate 22, the "U"-shaped buckle abuts against the upper abutting groove 211 and the lower abutting groove 221 at the same time. The "U"-shaped block is clamped by the upper abutting groove 211 and the lower abutting groove 221. The upper abutting groove 211 and the lower abutting groove 221 can clamp and limit the "U"-shaped buckle, reduce the possibility of the "U"-shaped buckle moving, and can detect the "U"-shaped buckle to reduce the possibility of the "U"-shaped buckle size not meeting the standard.
[0036] Reference Figure 1-Figure 4 Upper avoidance grooves 212 are respectively opened on both sides of the upper clamping plate 21, and lower avoidance grooves 222 are respectively opened on both sides of the lower clamping plate 22. The two lower avoidance grooves 222 are coaxially arranged with the drill bit 311 on the tool holder 31. When the driving mechanism drives the upper clamping plate 21 to rotate until it abuts against the lower clamping plate 22, the two upper avoidance grooves 212 are respectively coaxial with the two lower avoidance grooves 222. When the driving device 32 drives the two tool holders 31 to move, the drill bits 311 on the two tool holders 31 are respectively penetrated by the two lower avoidance grooves 222.
[0037] Reference Figure 1-Figure 4By setting the upper avoidance groove 212 and the lower avoidance groove 222, the drill bit 311 on the tool holder 31 passes through the upper avoidance groove 212 and the lower avoidance groove 222 to form the pin hole for the clamped "U"-shaped buckle; the pin hole forming operation is carried out in the upper clamping plate 21 and the lower clamping plate 22, so that the iron filings are discharged from the upper avoidance groove 212 and the lower avoidance groove 222, thereby reducing the possibility of safety hazards caused by iron filings splashing; at the same time, by observing the position between the drill bit 311 and the upper and lower avoidance grooves 222, it can be judged whether there is a large deviation in the installation of the drill bit 311, thereby reducing the possibility that the coaxiality of the two pin holes is difficult to ensure.
[0038] Reference Figure 1-Figure 4 A matching block 223 is fixedly connected to the lower clamping plate 22, and a matching groove 213 that can match the matching block 223 is provided on the upper clamping plate 21. When the driving assembly 23 drives the upper clamping plate 21 to rotate toward the side of the lower clamping plate 22 to abut against the lower clamping plate 22, the matching block 223 and the matching groove 213 cooperate with each other. The possibility of deviation between the positions of the upper clamping plate 21 and the lower clamping plate 22 when the upper clamping plate 21 rotates to abut against the lower clamping plate 22 is reduced. A second avoidance groove 2231 is provided on the matching block 223, and the second avoidance groove 2231 is coaxial with the lower avoidance groove 222. The second avoidance groove 2231 is used to avoid the drill bit 311, reducing the possibility of the drill bit 311 hitting the lower abutting plate.
[0039] Reference Figure 1-Figure 4 When drilling the anchor shackle 4, the "U"-shaped block is placed on the lower clamping plate, and the matching block 223 also plays a role of abutting the anchor shackle 4. The possibility of the "U"-shaped block bending due to the force of drilling during the drilling process is reduced.
[0040] Reference Figure 1-Figure 6 The driving assembly 23 includes an arc-shaped rack 231, a gear 232 and a first motor 233. The arc-shaped rack 231 is coaxial with the rotation axis of the upper clamping plate 21 and is slidably connected to the workbench 1 around the rotation axis of the upper clamping plate 21. The gear 232 is rotatably connected to the workbench 1 along the rotation direction of the upper clamping plate 21. The gear 232 is meshed with the arc-shaped rack 231. The first motor 233 is fixedly connected to the workbench 1. One end of the output shaft of the first motor 233 is coaxial and fixedly connected to the gear 232. The first motor 233 drives the gear 232 to rotate, and through the meshing connection between the gear 232 and the arc-shaped rack 231, the arc-shaped rack 231 moves around the rotation axis direction of the upper pressing plate, thereby rotating the upper pressing plate.
[0041] Reference Figure 1 and Figure 2The driving device 32 includes a lead screw 321 and a second motor 322. The lead screw is connected to the workbench 1 in a rotational manner along the sliding direction of the tool holder 31. The two ends of the lead screw 321 are respectively penetrated and threadedly connected to the two sets of tool holders 31. The threads at the two ends of the lead screw 321 have opposite rotation directions. The second motor 322 is fixedly connected to the workbench 1 and is used to drive the rotation of the lead screw 321. The second motor 322 drives the lead screw 321 to rotate. Through the threaded connection between the lead screw 321 and the two sets of tool holders 31, the two sets of tool holders 31 are moved along the axis direction of the lead screw 321. Since the threads at the two ends of the lead screw 321 have opposite rotation directions, the two sets of tool holders 31 move in opposite directions, so that the two sets of tool holders 31 can simultaneously perform pin hole forming operations on the clamped "U"-shaped block from both sides.
[0042] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
