Description

Technical Field

[0001] This utility model relates to the field of anchor chain shackle technology, and more specifically, it relates to a pin hole punching device and the anchor chain shackle processed therefrom. Background Technology

[0002] Anchor chain shackles are an important type of marine rigging, mainly used to connect anchor chains and sledgehammers. They consist of a U-shaped buckle and a cross pin. The U-shaped buckle has pin holes at both ends, and the cross pin engages with the pin holes by insertion.

[0003] During use, the first step is to remove the cross pin from the anchor chain shackle, then insert the "U" shaped buckle into the anchor chain ring to be connected, and finally connect the cross pin into the upper anchor chain ring to complete the connection between the anchor chain and the sinker.

[0004] However, in the existing technology, the processing of pin holes for anchor chain shackles mostly relies on drilling machines or machining centers; although these devices can provide high processing accuracy, the method of fixing anchor chain shackles is relatively simple in actual operation.

[0005] When the punch drills into the pin hole, it generates a large torque force. This torque force can easily cause the entire anchor chain shackle to deflect, which in turn causes the two pin holes to deviate in position. Once the pin hole is misaligned, the cross pin cannot be installed smoothly. This not only reduces the assembly efficiency of the anchor chain shackle, but may also affect the reliability and safety of its connection.

[0006] To address this issue, a pin-hole punching device and its fabricated anchor chain shackle are proposed to improve existing problems. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pin hole punching device and the anchor chain shackle processed therefrom.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a pin hole drilling device, comprising a machine tool, wherein a drilling mechanism is symmetrically arranged radially on the top of the machine tool, a support column is arranged in the middle of the drilling mechanism, and a fixing block is arranged on the top of the support column; the drilling mechanism includes a displacement cylinder, a displacement plate arranged at the telescopic end of the displacement cylinder, a stand arranged on the top of the displacement plate, a drilling motor arranged at one end of the stand, a spindle arranged at the output end of the drilling motor, and a drill bit arranged at the end of the spindle away from the drilling motor; the spindle is located inside the stand, and both ends of the spindle can penetrate the corresponding sidewalls of the stand.

[0009] By adopting the above technical solution, when it is necessary to drill holes at both ends of the chain shackle body, the chain shackle body can be placed on the fixed block first. Then, the displacement cylinder is activated to push the displacement plate to move, so that the corresponding drill bits approach the two ends of the chain shackle body. During this process, the drilling motor is activated, and its output end drives the spindle to rotate, so that the drill bits rotate synchronously and perform drilling operations on both ends of the chain shackle body, thereby achieving the purpose of drilling holes at both ends of the chain shackle body.

[0010] The present invention is further configured such that: sliders are provided at both ends of the bottom of the displacement plate, and a slide rail is provided below the sliders; the slide rail is located at the top of the machine tool, and the sliders can slide on the corresponding slide rails.

[0011] The present invention is further configured such that: a threaded post is provided at the top of the support post, the threaded post can be inserted into the support post, and a nut is threadedly connected to the threaded post.

[0012] By adopting the above technical solution, the support height of the fixed block can be adjusted by the extension and retraction of the threaded column within the support column, thereby adjusting the suspension height of the chain shackle body. Finally, the threaded column can be locked and limited by the nut.

[0013] The present invention is further configured such that: the bottom of the fixing block is connected to the end of the threaded column away from the support column, and the top of the fixing block is also provided with a fixing groove, which is arc-shaped.

[0014] By adopting the above technical solution, a fixing groove is also provided on the top of the fixing block. The fixing groove is arc-shaped, which can support the chain shackle body. Moreover, the arc-shaped groove fits the outer wall of the chain shackle body better, avoiding damage to the surface of the chain shackle body when drilling.

[0015] The present invention is further configured such that: a rotary cylinder is evenly arranged around the top of the machine tool, the rotating end of the rotary cylinder is provided with an abutting cylinder, and the telescopic end of the abutting cylinder is provided with an abutting plate.

[0016] The present invention is further configured such that: a vertical plate is provided on the top of the upright frame, a telescopic cylinder is provided on one side of the vertical plate, an electric gripper is provided on the telescopic end of the telescopic cylinder, and gripper plates are symmetrically provided on the clamping end of the electric gripper.

[0017] By adopting the above technical solution, the clamping direction of the claw plate is perpendicular to the clamping direction of the abutment plate, thereby achieving clamping in all directions. This avoids the problem that torque force can easily cause the entire anchor chain shackle to deflect, which in turn causes the position of the two pin holes to deviate. This improves the drilling accuracy and thus improves the assembly efficiency of the anchor chain shackle.

[0018] Anchor chain shackles, using the pin hole punching device described above, include an anchor chain shackle body, the anchor chain shackle body being inverted U-shaped, and pin holes being symmetrically opened at both ends of the anchor chain shackle body.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) When it is necessary to drill holes at both ends of the chain shackle body, the chain shackle body can be placed on the fixed block first, and then the displacement cylinder is started to push the displacement plate to move, so that the corresponding drill bits are close to both ends of the chain shackle body. During this process, the drilling motor is started, and its output end drives the spindle to rotate, so that the drill bits rotate synchronously and drill holes at both ends of the chain shackle body, thereby achieving the purpose of drilling holes at both ends of the chain shackle body.

[0021] (2) The support height of the fixed block can be adjusted by the extension and retraction of the threaded column within the support column, which in turn can adjust the suspension height of the chain shackle body. Finally, the threaded column can be locked by the nut.

[0022] (3) A fixing groove is also provided on the top of the fixing block. The fixing groove is arc-shaped, which can support the chain shackle body. The arc-shaped groove fits the outer wall of the chain shackle body better, avoiding damage to the outer surface of the chain shackle body when drilling.

[0023] (4) The clamping direction of the claw plate is perpendicular to the clamping direction of the abutment plate, so that clamping can be achieved in all directions. This avoids the problem that the torque force can easily cause the entire anchor chain shackle to deflect, which in turn causes the position of the two pin holes to deviate. This improves the drilling accuracy and thus improves the assembly efficiency of the anchor chain shackle. Attached Figure Description

[0039] 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.

[0040] 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.

[0041] Please see Figures 1-6 The present invention provides the following technical solution:

[0042] Example 1, see Figures 1-6 A pin hole punching device includes a machine tool 1, a punching mechanism 2 symmetrically arranged in the radial direction on the top of the machine tool 1, a support column 3 arranged in the middle of the punching mechanism 2, and a fixing block 4 arranged on the top of the support column 3.

[0043] The drilling mechanism 2 includes a displacement cylinder 21, a displacement plate 22 disposed at the telescopic end of the displacement cylinder 21, a stand 23 disposed at the top of the displacement plate 22, a drilling motor 24 disposed at one end of the stand 23, a main shaft 25 disposed at the output end of the drilling motor 24, and a drill bit 26 disposed at the end of the main shaft 25 away from the drilling motor 24; the main shaft 25 is located inside the stand 23, and both ends of the main shaft 25 can penetrate the corresponding side walls of the stand 23.

[0044] See Figures 1-6Furthermore, the anchor chain shackle uses the aforementioned pin hole punching device, which includes an anchor chain shackle body 9. The anchor chain shackle body 9 is inverted U-shaped, and pin holes 91 are symmetrically opened at both ends of the anchor chain shackle body 9.

[0045] When it is necessary to drill holes at both ends of the anchor chain shackle body 9, the anchor chain shackle body 9 can be placed on the fixed block 4 first. Then, the displacement cylinder 21 is started, pushing the displacement plate 22 to move, so that the corresponding drill bits 26 approach the two ends of the anchor chain shackle body 9. During this process, the drilling motor 24 is started, and its output end drives the spindle 25 to rotate, so that the drill bits 26 rotate synchronously and drill holes at both ends of the anchor chain shackle body 9, thereby achieving the purpose of drilling holes at both ends of the anchor chain shackle body 9.

[0046] See Figures 1-6 Furthermore, sliders 221 are provided at both ends of the bottom of the displacement plate 22, and slide rails 222 are provided below the sliders 221. The slide rails 222 are located at the top of the machine tool 1, and the sliders 221 can slide on the corresponding slide rails 222.

[0047] When the displacement cylinder 21 is activated, it pushes the displacement plate 22 to move, so that the corresponding drill bits 26 move closer to the two ends of the anchor chain shackle body 9. At the same time, the displacement plate 22 will also drive the corresponding slider 221 to slide on the corresponding slide rail 222, thereby achieving the purpose of guidance and improving the drilling accuracy of the drill bit 26.

[0048] See Figures 1-6 Furthermore, a threaded post 31 is provided at the top of the support post 3. The threaded post 31 can be inserted into the support post 3, and a nut 32 is threadedly connected to the threaded post 31.

[0049] The threaded post 31 extends and retracts within the support post 3, thereby adjusting the support height of the fixing block 4, which in turn adjusts the suspension height of the anchor chain shackle body 9. Finally, the threaded post 31 is locked in place by the nut 32.

[0050] See Figures 1-6 Furthermore, the bottom of the fixing block 4 is connected to the end of the threaded post 31 away from the support post 3, and the top of the fixing block 4 is also provided with a fixing groove 41, which is arc-shaped.

[0051] Among them, a fixing groove 41 is also provided on the top of the fixing block 4. The fixing groove 41 is arc-shaped, which can support the anchor chain shackle body 9. The arc-shaped groove fits the outer wall of the anchor chain shackle body 9 better, avoiding damage to the surface of the anchor chain shackle body 9 when drilling.

[0052] See Figures 1-6Furthermore, rotary cylinders 5 are evenly arranged around the top of the machine tool 1. The rotating end of the rotary cylinder 5 is provided with an abutting cylinder 6, and the telescopic end of the abutting cylinder 6 is provided with an abutting plate 61.

[0053] Two rotary cylinders 5 are located on both sides of one end of the anchor chain shackle body 9, and two other rotary cylinders 5 are located on both sides of the other end of the anchor chain shackle body 9. When drilling holes at both ends of the anchor chain shackle body 9, the rotary cylinders 5 are activated first, causing the abutment plates 61 to rotate 90 degrees and be positioned on both sides of the anchor chain shackle body 9 to be clamped. Then, the abutment cylinders 6 are activated, pushing the corresponding abutment plates 61 close to the side wall of the anchor chain shackle body 9, so that the four abutment plates 61 can clamp and fix the outer walls of both ends of the anchor chain shackle body 9.

[0054] See Figures 1-6 Furthermore, the top of the upright frame 23 is also provided with an upright plate 7, and a telescopic cylinder 8 is provided on one side of the upright plate 7. An electric gripper 81 is provided at the telescopic end of the telescopic cylinder 8, and a gripper plate 82 is symmetrically provided at the clamping end of the electric gripper 81.

[0055] When the telescopic cylinder 8 is activated, it pushes the claw plate 82 close to the outer wall of the anchor chain shackle body 9. Then, the electric pneumatic gripper 81 is activated, which drives the two claw plates 82 to move closer to each other and clamp the outer wall of the anchor chain shackle body 9, thereby achieving the purpose of clamping and fixing.

[0056] It should be noted that the clamping direction of the claw plate 82 is perpendicular to the clamping direction of the abutment plate 61, thereby enabling clamping in all directions. This avoids the problem that torque force can easily cause the entire anchor chain shackle to deflect, which in turn causes the position of the two pin holes to deviate. This improves the drilling accuracy and thus improves the assembly efficiency of the anchor chain shackle.

[0057] 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.
