Description

Technical Field

[0001] The invention belongs to the technical field of equipment for cutting or clearing surfaces, and in particular relates to a thorn removal device for welding a mooring chain. Background Art

[0002] Marine mooring anchor chains are key components for ship berthing and offshore oil mooring projects, and their quality directly affects safety and stability. The manufacturing process includes bar heating, horizontal bending, flash welding, etc. A welding seam is left on one side of the anchor chain ring after horizontal bending. After flash welding, loose hot welding burrs will form around the weld. In order to improve the surface quality of the anchor chain ring, these burrs need to be removed to achieve a smooth effect and ensure the reliability and durability of the anchor chain ring.

[0003] Common anchor chain welding deburring machines mainly rely on rotating blades. Such equipment is usually equipped with a rotating rocker arm on which a deburring tool is installed. During operation, the upper and lower parts of the anchor chain ring weld after flash welding are clamped vertically with a clamp. Due to location limitations, the deburring tool needs to be cantilevered and installed on the rocker arm. During operation, the front edge of the tool first swings downward to remove the burrs on both sides, and then the inner edge rotates around the center of the rocker arm (i.e. the center line of the weld) to completely remove the burrs after segmentation. Finally, the tool is reset to complete a working cycle. This structure of the deburring machine has obvious defects: the cantilever-mounted deburring tool is not rigid enough, the blade life is short, and the efficiency is affected. At the same time, it is difficult for the tool rotation center to be coaxial with the center line of the straight section of the ring weld, resulting in not only the inability to completely remove the burrs when removing them, but also the possibility of damaging the ring body. In addition, the tool adjustment process is also extremely complicated and difficult.

[0004] The published patent CN201455559U discloses a machine for removing anchor chain welding burrs. In this scheme, the method of removing welding burrs is changed to a method in which the tool is stationary and the vertically clamped chain link moves up and down to remove the welding burrs. The process of the chain link moving up and down is all working stroke, and there is no idle stroke, which improves work efficiency. The feed amount of the left and right cutting edges of the tool can be controlled by adjusting the working pressure of the tool holder feed cylinder, thereby avoiding the defect that a small amount of the straight section of the ring weld is also removed.

[0005] However, this solution ignores the phenomenon that the anchor chain links cross when they move vertically, which makes the welding joints of two adjacent links completely different in position, and cannot ensure that the welding joints are always located at the tool. At the same time, this solution has almost no fixing effect on the anchor chain. Once the anchor chain links are offset or distorted, the burr removal effect and efficiency will be greatly affected at the least, and the anchor chain links will be damaged at the worst, affecting the normal processing procedure. Summary of the invention

[0019] Beneficial effects: The invention is reasonably designed and has the following beneficial effects: 1. In the scheme of the present invention, the semicircular arc-shaped barb removal knife is exquisitely designed and can fit closely to the surface of the mooring chain. Under the coordinated action of the lifting assembly and the supporting assembly, the barb removal knife divides and accurately removes the left and right sides of the mooring chain, ensuring that the metal blocks and metal thorns generated at the welding point are completely removed, significantly improving the accuracy and overall quality of the barb removal; 2. In the scheme of the present invention, the arc-shaped clamping plate, with its unique elastic design, tightly wraps the mooring chain without affecting the up and down sliding of the mooring chain, plays a key correction role in the processing process, effectively preventing the mooring chain link from being distorted and offset due to uneven force, thereby ensuring the uniformity and consistency of the burr removal effect, making the final product more in line with the quality standards; 3. In the scheme of the present invention, the swing motor drives the rotating drum to rotate precisely within a limited range through its swing rod-type output end. This design enables the angle of the mooring chain to be flexibly adjusted. After the mooring chain moves up and down, the welding ports of the corresponding mooring chain links can always be aligned with the burr removal tool, which greatly enhances the adaptability and flexibility of the equipment and ensures continuous and efficient burr removal operations. 4. In the solution of the present invention, when the lifting assembly performs the lifting action, the second support assembly can ensure that the mooring chain maintains stable support in the vertical direction, effectively preventing the mooring chain from shaking or deflecting during the lifting process, thereby improving the stability and safety of the entire thorn removal process; 5. In the scheme of the present invention, by accurately controlling the movements of the lifting assembly and the second supporting assembly, it can be ensured that the semicircular arc-shaped burr removal knife maintains the best alignment with the welding joint of the mooring chain when cutting off the metal block and the metal burr. The precise alignment not only improves the accuracy of burr removal, but also reduces the risk of incomplete burr removal or damage to the mooring chain due to position deviation.

Before the clamping piece 2402 clamps the mooring chain, the arc-shaped clamping plate 2411 is located outside the arc-shaped groove 2410 and the clamping piece 2402, and the outer surface of the mooring chain squeezes and pushes the surface of the arc-shaped clamping plate 2411 to make it move into the arc-shaped groove 2410. At this time, the sliding rod 2412 pushes the circular top plate 2413 to squeeze the spring 2415, forming a reverse thrust force so that the arc-shaped clamping plate 2411 forms a non-fixed clamping of the mooring chain. Its function is to ensure that the mooring chain will not deviate instead of directly clamping it, so as to avoid excessive clamping that affects the efficiency of the mooring chain when it slides up and down between the arc-shaped clamping plates 2411 for de-thorning.

[0035] Combination Figure 4 and Figure 8As shown, the second support assembly 25 includes an inverted L-shaped bending connecting rod 2501, a force-bearing round rod 2502 is fixedly provided at the end of the vertical short leg of the L-shaped bending connecting rod 2501, a rotating part 2503 is provided at the end of the horizontal long leg of the L-shaped bending connecting rod 2501, and a second short-distance oil cylinder 2504 is provided above the rotating part 2503. One end of the cylinder body of the second short-distance oil cylinder 2504 is embedded in the bottom of the U-shaped support frame 21 and is connected by screws. The output end of the second short-distance oil cylinder 2504 is inserted into the inner side of the rotating part 2503 and is connected through a rotating shaft. A flip motor 2505 is provided at the bottom of the rotating part 2503, and a bracket connected to the bottom of the U-shaped support frame 21 is fixedly provided on the outside of the flip motor 2505. The output end of the flip motor 2505 is inserted into the rotating part 2503. The square key on the outer side of the output end of the motor 2505 is inserted into the keyway inside the rotating part 2503, and the output end of the flip motor 2505 slides a short distance inside the rotating part 2503. The flip motor 2505 drives the rotating part 2503 to rotate around the center of the circle of the output end of the second short-distance oil cylinder 2504; the flip motor 2505 drives the rotating part 2503 to rotate horizontally so that the stressed round rod 2502 originally in other directions is inserted into the mooring chain that needs to be processed at the bottom, and the second short-distance oil cylinder 2504 drives the rotating part 2503 and the L-shaped bent connecting rod 2501 to rise and fall vertically, so that the stressed round rod 2502 stretches the mooring chain downward to prevent the mooring chain from being distorted and affecting the deburring effect. After the deburring is completed, the second short-distance oil cylinder 2504 and the flip motor 2505 are reset in succession to repeat the working process.

[0036] Working principle: During the use of the present invention, the mooring chain is passed through the X-shaped channel in the middle of the rotating drum 1101, the end that has been welded and completed the thorn removal process is located at the top, and the end that has been welded but not thorn removed is located at the bottom. The uppermost mooring chain is connected to the external winding device to form a chain conveying effect. After the mooring chain reaches the predetermined position, the first oil cylinder 1401 is started and the output end is displaced and inserted into the ring sleeve 1403 on the side of the plug-in block 1402. The output end of the first oil cylinder 1401 supports the bottom of the crossbar of one of the mooring chain links. After that, the second support assembly 25 starts to work, and the flip motor 2505 drives the rotating member 2503 to rotate horizontally so that the force-bearing round rod 2502 originally in other directions is inserted into the mooring chain link that needs to be processed at the bottom. The high-torque motor 1204 and the sprocket 1205 drive the square slider 1203 to perform the lifting action through the chain. At the same time, the second short-distance cylinder 2504 drives the rotating member 2503 and the L-shaped bending connecting rod 2501 to lift vertically, so that the mooring chain is stretched and straightened at the upper and lower ends to prevent the mooring chain from being distorted and affecting the de-thorning effect. The screw motor 2407 drives the customized main screw 2405 to rotate, and the rotating shaft seat 2408 serves as the support at the other end to prevent the main screw 2405 from being offset and tilted. When the main screw 2405 formed by the connection of two left-handed and right-handed screws rotates, the two left-handed and right-handed inner threaded screw nuts 2409 are linked to move the two cylindrical bodies 2401 closer to or farther from the circular plate-shaped processing part 2406, thereby controlling the clamping part 2402 to clamp or release the mooring chain. The guide slider 2403 and the guide rail 2404 limit the travel direction of the cylindrical body 2401. Before 402 clamps the mooring chain, the arc-shaped clamping plate 2411 is located outside the arc-shaped groove 2410 and the clamping member 2402. The outer surface of the mooring chain squeezes and pushes the surface of the arc-shaped clamping plate 2411 to make it move into the arc-shaped groove 2410. At this time, the sliding rod 2412 pushes the circular top plate 2413 to squeeze the spring 2415, forming a reverse thrust force so that the arc-shaped clamping plate 2411 forms a non-fixed clamping of the mooring chain. Its function is to ensure that the mooring chain will not deviate instead of directly clamping it, so as to avoid clamping too tightly and affect the efficiency of the mooring chain when it slides up and down between the arc-shaped clamping plates 2411 to remove the thorns; After the preparation and clamping work is completed, one of the first short-distance oil cylinders 2202 pushes the sliding push block 2201 and the stab removal knife 23 close to the outer surface of the mooring chain, and the other set of sliding push blocks 2201 is away from the mooring chain at this time. When the inner wall of the semicircular limiting groove 2302 and the semicircular arc-shaped stab removal knife 2303 is close to the outer surface of the mooring chain, the mooring chain is driven up by the lifting component 12 and the second supporting component 25 so that the semicircular arc-shaped stab removal knife 2303 cuts off the metal blocks and metal stabs generated by welding, and the mooring chain is completed. After the half-side thorn removal work, one set of sliding push blocks 2201 is away from the mooring chain, and the other set of sliding push blocks 2201 and the thorn removal cutter 23 are close to the outer surface of the mooring chain. Then, the mooring chain is driven down by the lifting assembly 12 and the second supporting assembly 25 so that the semicircular arc-shaped thorn removal cutter 2303 cuts off the metal block and metal thorn produced by the welding of the other half side. In this process, the mooring chain slides between the two arc-shaped clamping plates 2411, and the arc-shaped clamping plates 2411 play a role in correcting the mooring chain to avoid deviation and distortion. After the burr removal work of the welding joint is completed, the first support assembly 14 and the second support assembly 25 are reset to the initial state, and the external winding device winds the mooring chain upward. At this time, the swing motor 1302 drives the connecting handle 1103 to swing back and forth through the swing rod style output end, so that the rotating cylinder 1101 rotates at a limited angle, thereby adjusting the angle of the mooring chain so that the welding joint is always located at the burr removal tool 23.
