Description

Technical Field

[0001] The present invention relates to the technical field of anchor processing, and particularly relates to a positioning device for ship anchor processing. Background Art

[0002] Ship anchors generally refer to devices or equipment used to fix or connect a ship to the seabed or other fixed objects; according to different usage environments and functional requirements, ship anchors can be divided into various types, such as single-arm anchors, ring anchors, hook-shaped anchors, trapezoidal anchors, and folding anchors, etc. Each type of anchor has its unique design features and applicable scenarios. The present invention designs with a ring anchor as an example.

[0003] The processing of anchors requires fixing the raw materials and performing accurate positioning to carry out precise cutting, drilling, and other operations. Existing processing positioning devices perform each processing step independently. The cut materials are taken to the drilling machine for re-fixing and positioning, which is very cumbersome and requires multiple positionings, making it easy to have inaccurate positioning. Summary of the Invention

[0004] In view of the above technical problems, the present invention discloses a positioning device for ship anchor processing, which can effectively solve the problems in the background art. When the present invention is in use, through the transfer positioning mechanism, it can connect and position between multiple processes of anchor processing, seamlessly docking the processes of fixing and positioning required for steps such as cutting and punching of the anchor, enabling the cut anchor after cutting the raw material to be accurately transferred to the turntable, and accurately placing the cut anchor between the positioning plate I and the positioning plate II, thereby making the positioning faster and more accurate. There is no need to re-position and calibrate in each process, greatly saving time and improving efficiency. When the present invention is in use, when the turntable rotates and turns to the area where the cut anchor is placed, the positioning plate II will be squeezed by the protrusion on the limit ring, so that the distance between the positioning plate II and the positioning plate I is widened, facilitating the placement of the cut anchor. After the cut anchor is placed, the turntable continues to rotate, and the positioning plate II will disengage from the protrusion of the limit ring and reset under the action of the compression spring III, thereby clamping and limiting the cut anchor.

[0037] In an alternative embodiment of the embodiment of the present invention, as Figure 8 , Figure 10 shown, the limit ring 29 is provided with an inner ring and an outer ring, and both the inner ring and the outer ring are provided with an inward protrusion.

[0038] In an alternative embodiment of the embodiment of the present invention, as Figure 10 shown, the motor 30 is a servo motor, with higher precision and more accurate positioning.

[0039] Working principle: When the present invention is in use, the transfer and positioning mechanism can be used to connect and position multiple processes of anchor processing, and the processes of anchor cutting, punching and other steps that need to be fixed and positioned can be seamlessly connected, so that the cutting anchor 26 of the raw material 7 after cutting can be accurately transferred to the turntable 22, and the cutting anchor 26 is accurately placed between the positioning plate I 24 and the positioning plate II 25, so that the positioning is faster and more accurate, and there is no need to reposition and calibrate in each process, which greatly saves time and improves efficiency; when the present invention is in use, when the turntable 22 rotates, it rotates to the area where the cutting anchor 26 is placed, and the positioning plate II 25 will be squeezed by the protrusion on the limit ring 29, so that the distance between the positioning plate II 25 and the positioning plate I 24 is widened, which facilitates the placement of the cutting anchor 26. After the cutting anchor 26 is placed, the turntable 22 continues to rotate, and the positioning plate II 25 will disengage from the protrusion of the limit ring 29, and reset under the action of the compression spring III 28, thereby clamping the cutting anchor 26 to limit the position.

[0040] When the present invention is used, the raw material 7 is first placed on the bottom frame 8, and then the hydraulic cylinder I3 is started to drive the connecting plate 4 to move downward, and the vertical pressing plate 5 on the connecting plate 4 moves downward accordingly. When the vertical pressing plate 5 contacts the raw material 7, the vertical pressing plate 5 stops moving, and the connecting plate 4 continues to move downward. At the same time, the compression spring I6 is compressed, and the elastic force generated causes the vertical pressing plate 5 to fix the raw material 7; at the same time, the hydraulic cylinder II 14 is started to drive the horizontal pressing plate 13 to clamp the front end of the raw material 7, and then wait for the raw material 7 to be cut;

[0041] After the raw material 7 is cut, the motor 30 is started to drive the turntable 22 to rotate, and the short shaft at the lower end of the positioning plate II 25 on the turntable 22 is squeezed by the protrusion of the limit ring 29, so that the positioning plate II 25 slides and the distance from the positioning plate I 24 is pulled away, so that the cutting anchor 26 after cutting is placed. Then the cylinder II 12 is started to drive the sleeve 9 to rotate ninety degrees, so that the cutting anchor 26 is placed between the positioning plate I 24 and the positioning plate II 25. Then the hydraulic cylinder II 14 releases the cutting anchor 26 and the sleeve 9 is reset; the turntable 22 is provided with inner and outer circles for placing the cutting anchor 26. The punching patterns of the inner and outer circles are different. If the pattern of the inner circle needs to be punched, the cylinder I 11 is started during the process of the sleeve 9 rotating ninety degrees, driving the telescopic bracket 10 to extend, so that the cutting anchor 26 falls on the punching position of the inner circle.

[0042] After being placed, the turntable 22 continues to rotate one grid. During the rotation, the short shaft at the lower end of the positioning plate II 25 is separated from the protrusion of the limit ring 29. Under the action of the compression spring III 28, the positioning plate II 25 is reset and the cutting anchor 26 is clamped. Then, the cutting anchor 26 can be punched. After the cutting anchor 26 is punched, it becomes the style of the punching anchor 27.

[0043] After the raw material 7 is cut, it is necessary to move the raw material 7 forward by a certain distance for the next cutting. The hydraulic cylinder III 21 is activated to drive the extrusion block 20 forward. When moving, the arc surface of the extrusion block 20 contacts the raw material 7, and the inclined surface on the other side of the extrusion block 20 contacts the inclined surface of the slider 18, so that the extrusion block 20 squeezes towards the raw material 7. When it is tightly squeezed, both the raw material 7 and the slider 18 will move forward, and the compression spring II 17 is compressed. After moving to the designated position, the vertical pressing plate 5 fixes the raw material 7. Subsequently, the hydraulic cylinder III 21 contracts, driving the extrusion block 20 to withdraw from between the slider 18 and the raw material 7. At the same time, the slider 18 is reset under the action of the compression spring II 17. In this way, one cutting and feeding step is completed. Repeating steps such as cutting, positioning, and punching can achieve continuous processing.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
