Description

Technical Field

[0001] The utility model relates to anchor chain processing, in particular to a workpiece position calibration mechanism for anchor chain processing. Background Art

[0002] Anchor chain refers to a special chain that connects the anchor and the hull and transmits the anchor's holding force. The anchor chain is composed of multiple chain links.

[0003] For example, the application number is CN202323550391.8. The utility model discloses a workpiece position calibration mechanism for anchor chain processing, which relates to the technical field of calibration mechanisms. The utility model places a metal bar between the fastening mechanism and the top of the supporting mechanism, and makes one end of the metal bar abut against the limit block, adjusts the position of the limit block on the top of the base plate, and then cuts out metal plates of different lengths. After the cutting is completed, the second push rod motor contracts to pull the movable block away from the fixed block, and the first push rod motor pulls the pressure block upward away from the base, so that the cut metal bar falls downward from the strip-shaped opening at the top of the base plate under the action of gravity.

[0004] Based on the search of the above patents and in combination with the mechanisms in the prior art, it was found that the above mechanism abuts one end of the metal bar against the limit block, and the abutment only means that the metal bar is in contact with the limit block, but is not fixed. If the metal bar is cut, the cut metal bar will accidentally pop out, which will affect the safety of the operator.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] In view of the problems in the related art, the present invention proposes a workpiece position calibration mechanism for anchor chain processing to overcome the above technical problems existing in the existing related art.

[0007] To this end, the specific technical solutions adopted in this utility model are as follows:

[0008] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0009] Furthermore, in order to enable the fastening arc plate to move between the vertical poles, the fastening assembly includes a bidirectional screw rod rotatably connected to the inside of the vertical pole, and a first slider is symmetrically provided on the bidirectional screw rod. The first slider is threadedly connected to the bidirectional screw rod, and one end of the first slider extends outside the vertical pole and is fixedly connected to the fastening arc plate.

[0010] Furthermore, in order to facilitate the stable movement of the fastening arc plate between the vertical poles, a guide rod is fixedly connected to the inside of the other vertical pole, and a second slider is symmetrically provided on the guide rod. The second slider is slidably connected to the guide rod, and one end of the second slider extends to the outside of the other vertical pole and is fixedly connected to the fastening arc plate.

[0011] Furthermore, in order to facilitate the rotation of the threaded rod, a side box is fixedly connected to one end of the outer surface of the frame, a side cavity is opened inside the side box, a driving shaft is rotatably connected in the side cavity, and the two ends of the driving shaft are respectively fixedly connected to a second bevel gear, and one end of the driving shaft extends to the outside of the side box and is connected to the output end of the driving motor.

[0012] Furthermore, in order to make the threaded rod rotate synchronously with the driving shaft, one end of the threaded rod extends into the side cavity and is fixedly connected to the first bevel gear, and the first bevel gear is meshed with the second bevel gear.

[0013] Furthermore, in order to facilitate the rotation of the forward and reverse screw rods, one end of the forward and reverse screw rods extends outside the fixed box and is connected to the output end of the fixed motor.

[0014] Furthermore, in order to increase the friction between the fixed arc plate and the metal bar, an anti-slip pad is fixedly connected to the inner surface of the fixed arc plate.

[0015] Furthermore, in order to facilitate the rotation of the bidirectional screw rod, one end of the bidirectional screw rod extends outside the vertical pole and is connected to the output end of the fastening motor.

[0016] The beneficial effects of the utility model are:

[0017] 1. By placing the metal bar between the fixed arc plates and starting the fixed motor, the fixed motor drives the forward and reverse screws to rotate in the fixed cavity, and makes the two sliding blocks slide towards each other on the forward and reverse screws. The sliding of the sliding blocks makes the fixed arc plates clamp the metal bar, which can fix the end of the metal bar to be cut, thereby preventing the metal bar from accidentally popping out after cutting, effectively improving the safety of anchor chain processing, and at the same time, calibrating and adjusting the front and rear positions of the metal bar to ensure the accuracy of metal bar processing.

[0018] 2. The drive motor works, and the drive motor drives the drive shaft to rotate in the side cavity, and the second bevel gear rotates accordingly. The second bevel gear engages with the first bevel gear, so that the threaded rod rotates in the moving cavity, and the moving block moves on the threaded rod. The movement of the moving block causes the metal bar on the fixed box to move accordingly, which is convenient for personnel to adjust the cutting length of the metal bar. At the same time, the left and right position of the metal bar is calibrated and adjusted, thereby ensuring the accuracy of metal bar processing.

[0019] 3. When the end of the metal bar to be cut is fixed on the fixed box, the tightening motor starts to work, driving the bidirectional screw rod to rotate in the vertical rod, and making the two first sliders slide toward each other on the bidirectional screw rod. The sliding of the first slider makes the tightening arc plate clamp the metal bar, which can help improve the accuracy of anchor chain processing. At the same time, the metal bar is calibrated and adjusted in the upper and lower positions, thereby ensuring the accuracy of metal bar processing. BRIEF DESCRIPTION OF THE DRAWINGS
