Description

Technical Field

[0001] This utility model relates to the field of ship forging positioning technology, specifically to a ship forging flaw detection and defect positioning device. Background Technology

[0002] The defect location device for ship forgings is used to fix forgings when detecting internal defects. During the flaw detection process, workers need to use such a device to fix the forgings. Existing defect location devices for ship forgings typically use clamping or pressing devices to fix the forgings. When fixing the forgings, the fixing device needs to be in direct contact with the surface of the forging, making it impossible to inspect the areas where the fixing device is in contact with the forging during flaw detection. The current solution is usually to remove the forging, change the fixing angle, and then perform flaw detection, which is very cumbersome. Therefore, we propose a defect location device for ship forgings. Utility Model Content

[0003] The purpose of this invention is to provide a device for locating defects in ship forgings to solve the problems mentioned in the background art.

[0004] Existing flaw detection and defect location devices for ship forgings cannot perform flaw detection inspections on the areas where the fixing device contacts the ship forging after the ship forging is fixed in place.

[0005] To achieve the above objectives, this utility model provides a defect location device for flaw detection in ship forgings, comprising a bracket, four positioning components arranged symmetrically in pairs on the upper side of the bracket, each positioning component including a lifting component and a support plate, a slot matching the support plate being formed in the middle of the bracket, a fixing component including a support block being fixedly mounted on the upper side of the support plate, a clamping component for fixing the ship forging being provided on one side of the support block, and a rotating component for adjusting the angle of the ship forging being provided on another side of the support block.

[0006] After the ship forging is placed in the middle of multiple fixed components, it is clamped and fixed by two symmetrical clamping components. During the inspection of the ship forging, the angle of the ship forging is adjusted by rotating the components to drive the clamping components. When inspecting the uninspected parts of the ship forging, the inspected parts of the ship forging are fixed by the other two clamping components.

[0007] As a further improvement to this technical solution, the clamping assembly includes a clamping block, a first telescopic rod is fixedly provided on the side of the clamping block near the support block, and a push rod is fixedly provided on the side of the support block away from the first telescopic rod, with one end of the first telescopic rod being fixedly connected to one end of the push rod piston rod.

[0008] The clamping blocks are used to clamp and fix the ship forgings, and the push rods are used to move the clamping blocks. Two mutually symmetrical push rods push two mutually symmetrical clamping blocks and move the two mutually symmetrical clamping blocks to the side closer to each other until the ship forgings are clamped and fixed.

[0009] As a further improvement to this technical solution, a side plate is fixedly provided at the end of the first telescopic rod away from the clamping block, and a second telescopic rod is fixedly provided symmetrically between the side plate and the clamping block. The side plate is located between the support block and the clamping block.

[0010] Two telescopic rods are used to support the clamping block. When the push rod pushes the clamping block, the two telescopic rods gradually extend and retract as the clamping block moves.

[0011] As a further improvement to this technical solution, the rotating assembly includes a gearbox, which is fixedly mounted on the side of the support block near the clamping block. A first gear is rotatably mounted inside the gearbox, and the piston rod of the push rod slides through the middle of the first gear's rotating shaft.

[0012] When the No. 1 gear rotates, it drives the piston rod of the push rod and the No. 1 telescopic rod to rotate, which in turn drives the clamping block to rotate. The clamping block then drives the ship forging to adjust its angle.

[0013] As a further improvement to this technical solution, a second gear is rotatably arranged inside the gearbox, and a chain is meshing between the first gear and the second gear. A second motor for driving the second gear to rotate is fixedly installed on the side of the support block away from the gearbox.

[0014] When the No. 2 motor starts, it drives the No. 2 gear to rotate. When the No. 2 gear rotates, it drives the chain to rotate, and at the same time, the chain drives the No. 1 gear to rotate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this defect location device for ship forgings, two symmetrical push rods push two clamping blocks toward each other, clamping the ship forging between them. The user then performs defect inspection on the forging. When it is necessary to inspect the surfaces where the clamping blocks contact the forging, the user operates two additional push rods to move the other two clamping blocks to clamp the inspected portion of the forging. The user then operates two more push rods to move the two clamping blocks that were initially in contact with the forging away from it, allowing for another defect inspection. This device allows for adjustment of the clamping position of the forging during positioning, eliminating the need to remove and reposition it. The operation is simple and quick, preventing the forging inspection device from failing to inspect the areas where the clamping blocks contact the forging, thus improving the inspection efficiency of ship forgings.

[0028] Example 1

[0029] Please see Figures 1-2 As shown, this embodiment provides a defect location device for ship forgings, including a bracket 1. Four positioning components 2 are arranged on the upper side of the bracket 1, and the four positioning components 2 are symmetrically arranged in pairs on the upper side of the bracket 1. The positioning components 2 include lifting components 21, and lifting components 21 include support plates 211. A slot matching the support plate 211 is opened in the middle of the bracket 1. A fixing component 22 is arranged on the upper side of the support plate 211. The fixing component 22 includes a support block 221, which is fixedly arranged on the upper side of the support plate 211. A clamping component 222 for fixing the ship forging is arranged on one side of the support block 221.

[0030] Please see Figures 1-4 As shown, the clamping assembly 222 includes a clamping block 2221, which is used to clamp and fix the ship forging. A first telescopic rod 2222 is fixedly installed on the side of the clamping block 2221 near the support block 221, and a push rod 2223 is fixedly installed on the side of the support block 221 away from the first telescopic rod 2222. One end of the first telescopic rod 2222 is fixedly connected to one end of the piston rod of the push rod 2223. The push rod 2223 is used to drive the clamping block 2221 to move. When using the device, the user first places the ship forging in the middle of multiple clamping blocks 2221. Then, the user pushes the two symmetrically positioned clamping blocks 2221 by operating the two symmetrically positioned push rods 2223, and drives the two symmetrically positioned clamping blocks 2221 to move towards each other until the ship forging is clamped and fixed.

[0031] Please see Figures 2-4 As shown, after the ship forging is fixed, the user performs flaw detection on the ship end piece by operating the flaw detection device. In order to prevent the clamping block 2221 from shaking, a side plate 2224 is fixedly installed at the end of the first telescopic rod 2222 away from the clamping block 2221. A second telescopic rod 2225 is symmetrically fixed between the side plate 2224 and the clamping block 2221. The side plate 2224 is located between the support block 221 and the clamping block 2221. The two second telescopic rods 2225 are used to support the clamping block 2221. When the push rod 2223 pushes the clamping block 2221, the two second telescopic rods 2225 gradually extend and retract with the movement of the clamping block 2221.

[0032] Please see Figures 2-4 As shown, a rotating assembly 223 is provided on one side of the support block 221. The rotating assembly 223 is used to adjust the angle of the ship forging. The rotating assembly 223 includes a gearbox 2231, which is fixedly installed on the side of the support block 221 near the clamping block 2221. A first gear 2232 is rotatably installed inside the gearbox 2231. The piston rod of the push rod 2223 slides through the middle of the rotating shaft of the first gear 2232. A protrusion is fixedly installed at one end of the first telescopic rod 2222 near the rotating shaft of the first gear 2232. The protrusion is located inside the rotating shaft of the first gear 2232, so that when the first gear 2232 rotates, it drives the first telescopic rod 2222 to rotate. When the first gear 2232 rotates, it drives the piston rod of the push rod 2223 and the first telescopic rod 2222 to rotate, and drives the clamping block 2221 to rotate. The clamping block 2221 drives the ship forging to adjust its angle.

[0033] Please see Figures 2-4 As shown, a second gear 2233 is rotatably mounted inside the gearbox 2231. A chain 2234 meshes between the first gear 2232 and the second gear 2233. A second motor 2235 is fixedly mounted on the side of the support block 221 away from the gearbox 2231 to drive the second gear 2233 to rotate. When the second gear 2233 rotates, it drives the chain 2234 to rotate. At the same time, the chain 2234 drives the first gear 2232 to rotate. After one side of the ship forging is inspected, the user starts the corresponding second motor 2235 to drive the second gear 2233 to rotate. The second gear 2233 drives the chain 2234 and the first gear 2232 to rotate. At the same time, the first gear 2232 drives the clamping block 2221 to rotate and adjust the angle of the ship forging.

[0034] Please see Figures 1-5As shown, when it is necessary to perform flaw detection on the position where the clamping block 2221 contacts the ship forging, the user operates the other two push rods 2223 to drive the other two clamping blocks 2221 to clamp the part of the ship forging that has been inspected. Then, the user operates the two push rods 2223 again to pull the two clamping blocks 2221 that were in contact with the ship forging away from the ship forging. A pad 212 is provided on the lower side of the support plate 211. Two vertical rods 213 are fixedly installed between the pad 212 and the bracket 1. The two vertical rods 213 are respectively fixedly installed at two corners of the pad 212 that are far apart from each other. The two vertical rods 213 are used to support the pad 212. Small holes matching the two vertical rods 213 are opened at both ends of the support plate 211. When the support plate 211 slides, it slides up and down along the direction of the two vertical rods 213.

[0035] Please see Figures 1-5 As shown, lead screws 214 are rotatably mounted on the upper side of the other two corners of the pad 212. The two lead screws 214 are respectively rotatably inserted into the two ends of the support plate 211. When the two lead screws 214 rotate, they drive the support plate 211 to slide up and down. A motor 215 for driving one lead screw 214 to rotate is fixedly mounted on the lower side of the pad 212. A synchronous belt 216 is meshed between the rotating shafts of the two lead screws 214. The synchronous belt 216 is located on the lower side of the pad 212. The user starts the motor 215 to drive one lead screw 214 and the synchronous belt 216 to rotate. At the same time, the synchronous belt 216 drives the other lead screw 214 to rotate and drive the support plate 211 to slide down until the fixing component 22 that is not used to fix the ship forging is completely slid to the lower side of the bracket 1. Then the user operates the flaw detection device again to inspect the uninspected parts of the ship forging.

[0036] In practical use, the ship forging flaw detection defect positioning device of this embodiment involves the user first placing the ship forging between multiple clamping blocks 2221. Then, the user operates two symmetrical push rods 2223 to push the two clamping blocks 2221 closer together, clamping the ship forging between the two clamping blocks 2221. The user then performs flaw detection on the ship forging. When it is necessary to inspect the surfaces of the two clamping blocks 2221 that are in contact with the ship forging, the user operates two other push rods 2223 to move the other two clamping blocks 2221 to clamp the inspected portion of the ship forging. Then, the user starts the corresponding No. 1 motor 215 to move the fixing component 22, which is not fixed to the ship forging, to the lower side of the bracket 1. The user then operates the two push rods 2223 again to move the two clamping blocks 2221 that were in contact with the ship forging away from the ship forging. The user then performs flaw detection on the ship forging again, improving the inspection efficiency of the ship forging.
