Description

Technical Field

[0001] This utility model relates to the field of hole-opening mechanism technology, and in particular to a hole-opening mechanism for processing steel plates in shipyards. Background Technology

[0002] In shipyards, it is often necessary to use corresponding drilling mechanisms to drill holes in the plates used for shipbuilding in order to facilitate the connection between the plates. The existing drilling devices achieve drilling by rotating the drill bit. During the drilling process, metal chips are generated and they fly around with the rotation of the drill bit, affecting the normal operation of the equipment by the workers.

[0003] For example, in the prior art, the patent with authorization announcement number CN220161337U discloses a hole-making mechanism for processing plate in a shipyard; the device starts the fan, and when the mounting cover moves down a certain distance, it can drive the extension cover to contact the plate. When the drill bit continues to move down, the spring compresses inside the fixed column, which shortens the overall length of the extension cover and the mounting cover and forms a relatively sealed space around the drill bit. Therefore, the fan can be used to suck the generated waste chips into the collection box through the connecting hose.

[0004] However, when using a fan to adsorb metal debris, the high density of the metal debris makes it difficult for the fan's airflow to lift it up, affecting the collection of debris. Furthermore, the extension cover and the mounting cover form a relatively enclosed space around the drill bit, preventing external air from reaching the drill bit. When the fan is turned on, it is difficult to generate airflow, affecting the normal collection of debris. Therefore, a hole-opening mechanism for processing steel plates in shipyards is designed to solve the above problems. Utility Model Content

[0019] 2. This utility model features a rubber scraper ring. After drilling, when metal debris needs to be collected from the magnetic suction cylinder, the fixed plate is pressed down. The fixed plate moves the rubber scraper ring downwards via the through rod. The sleeve spring is compressed, and the rubber scraper ring scrapes off the metal debris adsorbed in the magnetic suction cylinder, achieving the effect of collecting metal debris. After releasing the fixed plate, the elasticity of the sleeve spring allows the through rod and fixed plate to move upwards, and the rubber scraper ring returns to its original position, facilitating subsequent use.

[0020] 3. This utility model, by setting up a worktable, allows for drilling of the sheet metal. The sheet metal is placed on a suction cup on a second sliding plate, where it is held in place. During drilling, the first motor rotates, driving the first lead screw to rotate, which in turn moves the first sliding plate left and right, thus moving the sheet metal left and right. Meanwhile, the second motor rotates, driving the second lead screw to rotate, which in turn moves the second sliding plate in the inward and outward directions, thus moving the sheet metal in the inward and outward directions. This ensures that the drill bit is aligned with the drilling position on the sheet metal, eliminating the need to move the sheet metal to adjust the drilling position. The operation is simple and convenient. Attached Figure Description

[0029] Example:

[0030] like Figures 1-5 As shown, an embodiment of this utility model provides a hole-opening mechanism for processing steel plates in a shipyard, including a workbench 1, an inverted L-shaped bracket 2, a hydraulic rod 3, a hole-opening motor 4, and a drill bit 5. The inverted L-shaped bracket 2 is fixedly installed at the center of the right side of the workbench 1. The hydraulic rod 3 is installed on the outer side of the upper surface of the inverted L-shaped bracket 2. The hole-opening motor 4 is installed at the output end of the hydraulic rod 3. The drill bit 5 is installed at the output end of the hole-opening motor 4. A magnetic metal chip collection assembly is sleeved on the outer side of the hole-opening motor 4.

[0031] In this embodiment, the metal debris collection assembly includes a magnetic suction cylinder 6, a guide sleeve 601, a guide rod 602, a lifting collar 603, and an anti-detachment disc 604. The magnetic suction cylinder 6 is sleeved and disposed on the lower outer side of the perforated motor 4. Guide sleeves 601 are fixedly disposed on both the left and right sides of the outer surface of the magnetic suction cylinder 6. A guide rod 602 is disposed through the guide sleeve 601. A lifting collar 603 is fixedly disposed at the bottom of the guide rod 602, and an anti-detachment disc 604 is fixedly disposed at the top of the guide rod 602.

[0032] In this embodiment, the inner surface of the magnetic chuck 6 is magnetic, and the bottom horizontal height of the magnetic chuck 6 is higher than the bottom horizontal height of the drill bit 5, which facilitates the magnetic chuck 6 to adsorb and collect metal debris, and the magnetic chuck 6 will not affect the normal drilling of the drill bit 5.

[0033] In this embodiment, the diameter of the anti-detachment disc 604 is larger than the diameter of the central through hole of the guide sleeve 601, and when the anti-detachment disc 604 is attached to the upper surface of the guide sleeve 601, the bottom horizontal height of the guide sleeve 601 is lower than the bottom horizontal height of the drill bit 5, so the guide sleeve 601 can completely block the drill bit 5.

[0034] In this embodiment, the height of the lifting collar 603 is less than the distance between the bottom surface of the guide sleeve 601 and the bottom of the magnetic cylinder 6, so the lifting collar 603 will not affect the normal drilling of the drill bit 5.

[0035] By incorporating a metal debris collection component, during the drilling process, the ship is placed on the workbench 1, the drill bit 5 is aligned with the drilling position, the drilling motor 4 is turned on to drive the drill bit 5 to rotate, the hydraulic rod 3 extends to drive the drilling motor 4 to move downward, the lifting collar 603 first contacts the plate and moves upward, the guide rod 602 moves upward along the guide sleeve 601, the lifting collar 603, together with the magnetic suction cylinder 6, forms a relatively sealed space at the drilling position until the drill bit 5 contacts the drilling position, the drill bit 5 drills the plate, the metal debris generated during drilling can be blocked by the lifting collar 603 and the magnetic suction cylinder 6 to prevent splashing, and the metal debris can be attracted by the inner surface of the magnetic suction cylinder 6 to achieve the effect of collecting metal debris.

[0036] In this embodiment, a through rod 605 is provided through one side of the upper surface of the magnetic cylinder 6, a fixing plate 606 is fixedly provided at the top of the through rod 605, a rubber scraper ring 607 is fixedly provided at the bottom of the through rod 605, and a sleeve spring 608 is fixedly provided between the bottom surface of the fixing plate 606 and the upper surface of the magnetic cylinder 6.

[0037] In this embodiment, the outer diameter of the rubber scraper ring 607 is equal to the inner diameter of the magnetic suction cylinder 6, and the rubber scraper ring 607 is embedded in the magnetic suction cylinder 6, which facilitates the rubber scraper ring 607 to clean the inner surface of the magnetic suction cylinder 6.

[0038] In this embodiment, when the sleeve spring 608 is in its naturally extended state, the rubber scraper ring 607 is located above the inner side of the magnetic suction cylinder 6, and when the sleeve spring 608 is in its maximum compressed state, the bottom horizontal height of the rubber scraper ring 607 is equal to the bottom horizontal height of the magnetic suction cylinder 6.

[0039] With the rubber scraper ring 607 installed, when metal debris needs to be collected from the magnetic suction cylinder 6 after drilling, the fixed plate 606 is pressed down. The fixed plate 606 moves the rubber scraper ring 607 downward through the through rod 605. The sleeve spring 608 is in a compressed state, and the rubber scraper ring 607 scrapes off the metal debris adsorbed in the magnetic suction cylinder 6, achieving the effect of collecting metal debris. After the fixed plate 606 is released, the elasticity of the sleeve spring 608 can make the through rod 605 and the fixed plate 606 move upward, and the rubber scraper ring 607 returns to its original position for convenient subsequent use.

[0040] In this embodiment, the workbench 1 includes a first motor 101, a first lead screw 102, a first slide plate 103, a transverse rail 104, a second motor 105, a second lead screw 106, a second slide plate 107, and a longitudinal rail 108. The first motor 101 is mounted on the left side of the upper surface of the workbench 1 via a mounting plate. The output end of the first motor 101 is equipped with the first lead screw 102, and the first slide plate 103 is threaded onto the first lead screw 102. The transverse rail 104 is fixedly provided on both the inner and outer sides of the upper surface of the workbench 1. The second motor 105 is mounted on the outer side of the upper surface of the first slide plate 103 via a mounting plate. The output end of the second motor 105 is equipped with the second lead screw 106, and the second slide plate 107 is threaded onto the second lead screw 106. The longitudinal rail 108 is fixedly provided on both the left and right sides of the upper surface of the first slide plate 103. Suction cups 109 are fixedly provided at the four corners of the upper surface of the second slide plate 107.

[0041] In this embodiment, the first slide plate 103 slides on the transverse track 104, and the second slide plate 107 slides on the longitudinal track 108, ensuring the stability of the left and right movement of the first slide plate 103 and the stability of the inward and outward movement of the second slide plate.

[0042] With the worktable 1 in place, when drilling holes in the board, the board is placed on the suction cup 109 on the second sliding plate 107. The suction cup 109 adheres to and positions the board. During the drilling process, the first motor 101 rotates, driving the first lead screw 102 to rotate, which in turn moves the first sliding plate 103 left and right, thus moving the board left and right. Meanwhile, the second motor 105 rotates, driving the second lead screw 106 to rotate, which in turn moves the second sliding plate 107 in the inward and outward directions, thus moving the board in the inward and outward directions. This ensures that the drill bit 5 is aligned with the drilling position on the board, eliminating the need to move the board to adjust the drilling position. The operation is simple and convenient.

[0043] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
