[0002] Ship processing refers to the process of manually or mechanically manufacturing numbered materials into hull parts that meet the drawings and process requirements. It covers the entire process from making plates or profiles into hull parts. The quality of ship processing is related to the structural strength, safety performance and overall quality of the ship.

[0003] Although there are many burrs produced by processing steel plates with low hardness and poor wear resistance, such as ordinary carbon steel, low alloy steel, stainless steel, etc., the burrs are easy to clean due to the low hardness of the steel plate material. However, marine steel plates are a special type of steel, mainly used to manufacture ships and offshore structures. Due to the harsh working environment of ships, in order to ensure the life of the hull, marine steel plates generally have excellent corrosion resistance, wear resistance, high strength and high toughness. The burrs produced by processing such high-strength and high-toughness steel plates have a high degree of hardness. For example, the patent disclosed in CN113414663B involves a burr removal device for marine castings, including a processing table, a lateral moving device, A vertical moving device, a burr removal component, and a turntable; the turntable is located at the center of the upper end of the processing table, the lateral moving device is located on the processing tables on the left and right sides of the turntable, the vertical moving device is located on the lateral moving device, and the burr removal component is located on the vertical moving device; the burr removal device provided by the patent can quickly remove burrs on the uneven surface of marine castings, but the burr removal device has no corresponding burr detection structure, and the burrs can only be found by workers visually, and then the burr removal device is used for deburring.

DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 10 As shown, the purpose of this embodiment is to provide a ship steel plate surface deburring processing device, including a fixing component 1 and a polishing component 2 arranged on the fixing component 1; The fixing assembly 1 comprises a pair of clamping members 11 fixed to the ship steel plate, and a suspension rail 12 is connected between the two clamping members 11; The polishing assembly 2 includes a sliding member 21 which is slidably connected to the hanging rail 12. The sliding member 21 is slidably connected to a grinding member 22 for removing burrs. A detection body is provided in the sliding member 21 for controlling the grinding member 22 to slide downward. The detection body contacts the surface of the ship steel plate. The device is fixed on the ship steel plate by two clamping members 11, pushing the sliding member 21 to move along the hanging rail 12. During movement, the detection body contacts the surface of the ship steel plate. When there are burrs on the surface of the ship steel plate and the detection body contacts the burrs, under the continuous movement of the sliding member 21, the detection body is driven by the burrs to slide horizontally along the sliding member 21. When the burr and the detection body move to the bottom of the grinding member 22, the detection body controls the sliding member 21 and the hanging rail 12 to remain relatively fixed, and the detection body controls the grinding member 22 to move downward to grind the burr, thereby facilitating rapid detection and processing of the burr.

[0023] The above structure is disclosed as follows: First, the device needs to be fixed on the ship steel plate. The clamping part 11 includes a connecting rod 111 and a support arm 112 hingedly connected to both ends of the connecting rod 111. The bottom of the support arm 112 is in contact with the upper surface of the edge of the ship steel plate. The outer side of the support arm 112 is connected to a clamping plate 113 by a screw. The clamping plate 113 is in contact with the lower surface of the edge of the ship steel plate. The ship steel plate is clamped up and down by the support arm 112 and the clamping plate 113, so that the device can be fixed on the ship steel plate.

[0024] Then a connecting plate 114 is sleeved on the connecting rod 111, and the hanging rail 12 includes a pair of guide rails 121. Both ends of the guide rails 121 are connected to the connecting plate 114. The side walls of the guide rails 121 are provided with a first sliding groove 122 that passes through the surface thereof. The sliding member 21 includes a connecting bracket 211 that passes through the first sliding groove 122. The connecting bracket 211 is slidingly connected to the guide rail 121 through the first sliding groove 122. By pushing the sliding member 21 to move along the first sliding groove 122, the sliding member 21 can drive the detection body to move in a straight line on the surface of the ship steel plate, thereby "scanning" the surface of the ship steel plate.

[0025] When there are burrs on the surface of the ship steel plate and the detection body contacts the burrs, the detection body includes an opposing body 212 and a control structure connected to the opposing body 212, the opposing body 212 includes a pair of card plates 2121, the inner ends of the card plates 2121 are plugged together by an inserted shaft 2123, the top of the outer end of the card plate 2121 is provided with a plate shaft 2122, and a third sliding groove 213 is provided on the plate extending inward from the bottom end of the connecting bracket 211, the plate shaft 2122 is located in the third sliding groove 213, the plate shaft 2122 is slidably connected to the third sliding groove 213, and the third A groove 2131 for clamping the plate shaft 2122 is provided at one end of the sliding groove 213. When the clamping plate 2121 contacts the burr, the sliding member 21 is continuously pushed, so that the clamping plate 2121 clamped by the burr slides along the third sliding groove 213. The distance between the two clamping plates 2121 increases during sliding until the plate shaft 2122 moves to one end of the third sliding groove 213 and is clamped in the groove 2131. The inserted shaft 2123 is just disengaged, so that the two clamping plates 2121 are no longer connected. At this time, the burr on the surface of the ship steel plate is located below the grinding member 22.

[0026] When the card plate 2121 moves until the plate shaft 2122 is stuck in the groove 2131, the control structure includes a first roller 2111 rotatable inside the left and right ends of the connecting bracket 211, the bottom end of the first roller 2111 is coaxially connected with a reel 2112, the reel 2112 is connected to the card plate 2121 through a rope, the first roller 2111 is connected to the inner wall of the connecting bracket 211 through a volute spring 2113 arranged on the surface, the first roller 2111 is provided with a first driving tooth on the surface of the first roller 2111, the first driving tooth is meshed with a first driving shaft 2114, the bottom of the first driving shaft 2114 is threadedly connected with a bite block 2115, the bite block 2115 is slidably connected to the inner wall of the connecting bracket 211 up and down, the bottom of the bite block 2115 passes through the surface of the connecting bracket 211, and the bite block 2115 It is engaged with the inner wall of the first sliding groove 122. When the sliding member 21 is continuously pushed and the card plate 2121 stuck by the burr slides along the third sliding groove 213, the card plate 2121 drives the reel 2112 to rotate through the connected rope, and then drives the first roller 2111 to rotate, so that the first roller 2111 drives the meshing first driving shaft 2114 to rotate, and then the bite block 2115 threadedly connected to the first driving shaft 2114 moves downward. When the card plate 2121 moves to the point where the plate shaft 2122 is stuck in the groove 2131, the bite block 2115 is just stuck in the inner wall of the first sliding groove 122. At this time, the sliding member 21 and the suspension rail 12 remain relatively fixed to prevent the sliding member 21 from continuing to move, so that the grinding member 22 can grind and polish the burrs.

[0027] After the sliding member 21 and the suspension rail 12 are relatively fixed, the grinding member 22 needs to move down to contact the burr and process the burr. The grinding member 22 includes a grinding bracket 221 and a polishing structure 222 arranged in the middle of the grinding bracket 221 for grinding. Blocks 2211 are arranged at the front and rear ends of the grinding bracket 221. A second sliding groove 2116 is correspondingly opened on the side wall of the connecting bracket 211. The block 2211 is located in the second sliding groove 2116. The block 2211 is connected to the second sliding groove 2116 by sliding up and down. The wall is elastically connected with a clamping shaft 2212, the inner wall of the connecting bracket 211 is provided with a clamping groove 2117 connected with the second sliding groove 2116, the clamping shaft 2212 is located in the clamping groove 2117, the clamping shaft 2212 and the clamping groove 2117 are clamped and matched, the surface of the first roller 2111 is provided with a second driving tooth, the second driving tooth is meshed with a second driving shaft 2118, the second driving shaft 2118 is rotatably connected with the inside of the connecting bracket 211, the surface of the second driving shaft 2118 is threadedly connected with a baffle 2119, and the baffle 2119 is located in the clamping groove 2117. The baffle plate 2119 is connected to the inner wall of the card slot 2117 by sliding forward and backward. Under normal circumstances, the grinding member 22 is located at a higher position, that is, the card shaft 2212 is stuck in the card slot 2117 to fix the grinding bracket 221 and the polishing structure 222 at the high point of the second sliding groove 2116, and the bottom of the polishing structure 222 does not contact the surface of the ship steel plate. This can reduce the resistance encountered by the sliding member 21 when it moves, and it is also convenient to move the polishing structure 222 to the top of the burr. When the burr is located below the polishing structure 222 and slides on the card plate 2121, While the sliding member 21 and the suspension rail 12 remain relatively fixed, the rotation of the first roller 2111 will drive the second driving shaft 2118 meshing with it to rotate, and then the second driving shaft 2118 drives the baffle 2119 threadedly connected to it to slide along the inner wall of the slot 2117, contacting and pushing the card shaft 2212 into the block 2211, so that the card shaft 2212 disengages from the slot 2117 and is no longer stuck. Under the action of its own weight, the grinding bracket 221 slides down along the second sliding groove 2116 until the bottom of the polishing structure 222 contacts the burr.

[0028] After contacting the burr, the burr needs to be processed. A lifting groove 2213 is opened in the middle of the grinding bracket 221. The polishing structure 222 includes a support plate 2221 with two ends located in the lifting groove 2213. The two ends of the support plate 2221 are connected to the lifting groove 2213 for sliding up and down. A motor 2222 is provided on the support plate 2221. A grinding disk 2223 for grinding is connected to the bottom of the motor 2222. The grinding disk 2223 is driven by the motor 2222 to rotate continuously. When the grinding bracket 221 slides down along the second sliding groove 2116 to the grinding disk 2223 and contacts the burr, the grinding disk 2223 can grind and polish the burr. In addition, a surrounding edge 2224 that can move up and down is inserted at the bottom of the support plate 2221. By providing the surrounding edge 2224, when the grinding disk 2223 contacts and grinds the burr, the surrounding edge 2224 can be shielded to prevent waste generated by grinding from flying out, thereby ensuring the safety of the staff.

[0029] It is worth noting that when the two card plates 2121 are disconnected, if the card plates 2121 are not moved away from the grinding disk 2223 in time, the card plates 2121 located below the grinding disk 2223 will hinder the grinding and polishing process. A support foot 214 is provided at the bottom end of the connecting bracket 211, and the support foot 214 is connected to the surface of the card plate 2121 through an elastic band 215. The tops of the front and rear ends of the grinding bracket 221 are connected to the lower surface of the top of the connecting bracket 211 through the connecting springs 2214. When the two card plates 2121 are disconnected, the elastic band 215 pulls the card plates 2121 away from the area below the grinding disk 2223, and the connecting springs 2214 can reduce the sliding speed of the grinding bracket 221, giving the card plates 2121 enough time to disconnect.

[0030] After the burr grinding process is completed, the grinding bracket 221 is lifted up, and the plate shaft 2122 is separated from the groove 2131. After the two clamping plates 2121 are plugged and connected through the plug shaft 2123, under the action of the spiral spring 2113, the clamping plate 2121 is driven by the reel 2112 through the rope to reset along the third sliding groove 213, and the first roller 2111 is reversed to release the relative fixation of the sliding member 21 and the suspension rail 12, and the baffle 2119 is reset, and the clamping shaft 2212 can be clamped into the clamping groove 21 17, continue to push the sliding member 21 to move, and "scan" the surface of the ship steel plate along the track. After the "scan" is completed in this area, in order to be able to "scan" the adjacent area, a screw sleeve 115 is provided in the connecting plate 114, and the connecting rod 111 passes through the screw sleeve 115. The screw sleeve 115 is threadedly connected to the connecting rod 111. By rotating the screw sleeve 115 threadedly connected to the connecting rod 111, the connecting plate 114 can be driven to move, and then the guide rail 121 can be driven to move, thereby facilitating the "scanning" of the adjacent area.
