Description

Technical Field

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

[0002] Ship anchors in a broad sense refer to devices or equipment used to fix or connect ships 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 anchors, trapezoidal anchors and folding anchors. Each type of anchor has its own unique design features and applicable scenarios. The present invention is designed using a ring anchor as an example.

[0003] The processing of anchors requires that the raw materials be fixed and positioned so that precise cutting and drilling operations can be performed. The existing processing and positioning devices perform each processing step independently, and the cut materials are taken to the drilling machine for re-fixation and positioning, which is very cumbersome and requires multiple positioning, which is prone to inaccurate positioning.

[0036] In an optional implementation manner of the embodiment of the present invention, as Fig.10 As shown, the motor 30 is a servo motor, which has higher precision and more accurate positioning.

[0037] 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.

[0038] 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; 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. 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. When the cutting of the raw material 7 is completed, the raw material 7 needs to be moved forward a certain distance for the next cutting. The hydraulic cylinder III 21 is started to drive the extrusion block 20 to move 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 is squeezed toward the raw material 7. When the extrusion is tight, the raw material 7 and the slider 18 will move forward. The compression spring II 17 is compressed. After moving to the specified position, the vertical pressing plate 5 fixes the raw material 7. Then the hydraulic cylinder III 21 contracts, driving the extrusion block 20 to be pulled out 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 loading step is completed. Repeating the cutting, positioning, punching and other steps can achieve continuous processing.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
