Description

Technical Field

[0001] This utility model relates to the field of stern tube boring technology, specifically a device for boring stern tubes of ships. Background Technology

[0002] A boring machine is a specialized machine for processing deep holes in hydraulic cylinders, air cylinders, and other hydraulic cylinders. It can also process spindle holes, blind holes, and stepped holes in machine tools. The machine tool can not only perform various drilling and boring operations, but also roll forming. During drilling, internal or external chip removal methods are used. Boring machines are used when boring the stern tubes of ships.

[0003] The announcement number is CN221848732U, which discloses "a device for boring a section stern tube of a ship, including a device base, a mounting frame that is slidably connected inside the device base, two fixing grooves that are symmetrically opened on the outer wall of the mounting frame, a rack that is fixed inside the fixing groove, a fixing plate that is fixed on one side of the device base, a drive motor that is fixed to the outer wall of the fixing plate by bolts, a gear that is fixed through the power output shaft of the drive motor and the lower surface of the gear that meshes with the upper surface of the rack".

[0004] There are still some drawbacks in its use. When boring, the tool is directly inserted into the stern tube of the ship for processing. The mounting bracket is relatively long, and the mounting bracket at the tool is prone to shaking when the tool is making circular motion, which causes the boring position of the stern tube to deviate. In addition, the metal chips generated by boring fall directly into the stern tube and onto the ground, which is not easy to clean. Utility Model Content

[0005] The purpose of this invention is to provide a device for boring a ship stern tube, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A boring device for a ship's stern tube includes a mounting base plate, a rotating shaft rotatably connected inside the mounting base plate, a cutting tool mounted at one end of the rotating shaft, a motor capable of driving the rotating shaft to rotate located on one side of the mounting base plate, and an auxiliary mechanism located at one end of the rotating shaft. The auxiliary mechanism includes:

[0008] A reinforcement component is provided at one end of the rotating shaft. The reinforcement component includes a fixed cover, a bearing is fixedly installed inside the fixed cover, a square groove collar is fixedly installed on the inner ring of the bearing, and a square rod that is movably inserted into the square groove collar is fixedly installed at one end of the rotating shaft.

[0009] Two clamping components are symmetrically arranged on the outside of the fixing cover;

[0010] The adjustment component is located on one side of the fixed cover;

[0011] A collection component is disposed outside the fixed cover, the collection component including a dust collection cover.

[0012] Furthermore, two adjustable telescopic rods are symmetrically fixedly installed on the outer surface of the fixed cover. One end of the adjustable telescopic rod is fixedly connected to the dust collection cover. An electromagnet is fixedly embedded in one side of the inner surface of the dust collection cover. An air-gathering pipe is fixedly installed at the lower end of the dust collection cover.

[0013] Furthermore, telescopic plates are symmetrically fixedly installed on the outer surface of the fixed cover, and a slide rail is fixedly installed at one end of the telescopic plate, with a slider slidably connected inside the slide rail.

[0014] Preferably, the clamping assembly includes:

[0015] A bidirectional screw is rotatably connected inside the slider;

[0016] Two No. 1 threaded sleeves are symmetrically screwed into the outside of the bidirectional screw.

[0017] Preferably, a clamping block is fixedly installed on one side surface of the No. 1 threaded sleeve, and a sliding rod is fixedly installed on one side surface of the slider, the sliding rod sliding through the two No. 1 threaded sleeves.

[0018] Preferably, the adjustment component includes:

[0019] The U-shaped frame is fixedly installed on one side of the fixed cover.

[0020] Two unidirectional screws are symmetrically rotated and connected inside the U-shaped frame;

[0021] Adjust the handle to rotate the connection to one side of the U-shaped frame;

[0022] The No. 2 threaded sleeve is screwed onto the outside of the one-way screw.

[0023] Preferably, a first bevel gear is fixedly installed at one end of the unidirectional screw, a second bevel gear is fixedly installed at one end of the adjusting handle, and the second bevel gear is meshed and connected to the two first bevel gears for transmission. The second threaded sleeve is fixedly connected to the movable end of the telescopic plate.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. By inserting a square rod into the square groove collar, one end of the rotating shaft is limited. The slider slides inside the slide rail, allowing the fixed cover to move with the rotating shaft. This facilitates insertion into the ship's stern tube to limit the rotating shaft. By installing a reinforcing component on one side of the ship's stern tube, and in conjunction with the mounting base plate, the two ends of the rotating shaft are limited, improving the stability of the tool rotation, preventing tool wobbling from causing borehole offset in the ship's stern tube, and improving the borehole accuracy.

[0026] 2. Rotate the adjusting handle to make the two one-way screws rotate, causing the telescopic plate to extend and retract, adjust the position of the clamping assembly, rotate the two-way screws to move the two No. 1 threaded sleeves inward, clamping them from the outside of the ship's stern tube, so that it can clamp ship stern tubes of different outer diameters.

[0027] 3. An external filter and fan are connected to the air collection pipe, which generates suction at the dust collection hood. At the same time, the electromagnet attracts the metal chips, collecting the fallen metal chips on the surface of the electromagnet. After processing, the electromagnet is de-energized, allowing the metal chips to be discharged from the air collection pipe. Thus, by attracting and collecting the metal chips, the metal chips generated by boring are easy to clean. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-5 In this embodiment of the present invention, a boring device for a ship's stern tube includes a mounting base 1. A rotating shaft 101 is rotatably connected inside the mounting base 1. A cutting tool 103 is provided at one end of the rotating shaft 101. The rotating shaft 101 is inserted into the ship's stern tube, so that the cutting tool 103 bores the ship's stern tube. A motor 102 capable of driving the rotating shaft 101 to rotate is provided on one side of the mounting base 1. An auxiliary mechanism is provided at one end of the rotating shaft 101. The auxiliary mechanism includes a reinforcing component 2 disposed on the rotating shaft. At one end of 101, the reinforcing component 2 includes a fixed cover 201, a bearing 202 is fixedly installed inside the fixed cover 201, a square groove collar 203 is fixedly installed on the inner ring of the bearing 202, a square rod 104 is fixedly installed at one end of the rotating shaft 101 and is movably inserted into the square groove collar 203, two clamping components 3 are symmetrically arranged on the outside of the fixed cover 201, an adjusting component 4 is arranged on one side of the fixed cover 201, and a collecting component 5 is arranged on the outside of the fixed cover 201. The collecting component 5 includes a dust collection cover 502.

[0036] Specifically, the reinforcement component 2 is installed from the other side of the ship's stern tube. The square rod 104 is inserted into the square groove collar 203 to limit one end of the rotating shaft 101. The reinforcement component 2 is fixed to the other side of the ship's stern tube by the clamping component 3. The position of the two clamping components 3 is adjusted by the adjusting component 4 so that they can clamp ship stern tubes with different outer diameters. Then, the metal chips generated by boring are collected by the collecting component 5.

[0037] Example 1

[0038] like Figure 3 As shown, in this embodiment, a telescopic plate 204 is symmetrically fixedly installed on the outer surface of the fixed cover 201, and a slide rail 205 is fixedly installed on one end of the telescopic plate 204. A slider 206 is slidably connected inside the slide rail 205.

[0039] In this embodiment, the telescopic plate 204 extends and retracts as the clamping assembly 3 moves, increasing the stability of the clamping assembly 3. At the same time, the slider 206 slides inside the slide rail 205, allowing the fixing cover 201 to move with the rotating shaft 101. This facilitates reaching inside the ship's stern tube to limit the rotation of the rotating shaft 101. Thus, by installing the reinforcing assembly 2 on one side of the ship's stern tube and cooperating with the mounting base plate 1 to limit both ends of the rotating shaft 101, the stability of the tool 103 during rotation is improved, avoiding the deviation of the ship's stern tube boring caused by the shaking of the tool 103, and improving the boring accuracy.

[0040] like Figure 3 and Figure 4 As shown, in this embodiment, the clamping assembly 3 includes: a bidirectional screw 301 rotatably connected to the inside of the slider 206, and two No. 1 threaded sleeves 302 symmetrically screwed onto the outside of the bidirectional screw 301; a clamping block 303 is fixedly installed on one side surface of the No. 1 threaded sleeve 302, and a sliding rod 304 is fixedly installed on one side surface of the slider 206, the sliding rod 304 slidingly penetrating through the two No. 1 threaded sleeves 302.

[0041] In practice, rotating the bidirectional screw 301, through its screw-in connection with the two No. 1 threaded sleeves 302, and under the sliding limit of the slide rod 304 and the No. 1 threaded sleeves 302, causes the two No. 1 threaded sleeves 302 to move inward and clamp them from the outside of the ship's stern tube.

[0042] like Figure 3 and Figure 5 As shown, in this embodiment, the adjustment component 4 includes: a U-shaped frame 401 fixedly installed on one side surface of the fixed cover 201; two one-way screws 402 symmetrically rotatably connected to the inside of the U-shaped frame 401; an adjustment handle 405 rotatably connected to one side surface of the U-shaped frame 401; and a second threaded sleeve 403 screwed onto the outside of the one-way screws 402. A first bevel gear 404 is fixedly installed at one end of the one-way screw 402, and a second bevel gear 406 is fixedly installed at one end of the adjustment handle 405. The second bevel gear 406 meshes and drives with the two first bevel gears 404. The second threaded sleeve 403 is fixedly connected to the movable end of the telescopic plate 204.

[0043] In practice, rotating the adjusting handle 405 causes the two one-way screws 402 to rotate through the transmission of the first bevel gear 404 and the second bevel gear 406. The two one-way screws 402 are connected by the screw thread sleeve 403. Under the sliding limit of the telescopic plate 204 itself, the second thread sleeve 403 drives the movable end of the telescopic plate 204 to move, so that the telescopic plate 204 can extend and retract, adjusting the position of the clamping assembly 3 so that it can clamp the stern tubes of different outer diameters.

[0044] Example 2

[0045] Based on Example 1, in order to overcome the problem that metal shavings generated by boring are not easy to collect.

[0046] like Figure 1 and Figure 4 As shown, in this embodiment, two adjustable telescopic rods 501 are symmetrically fixedly installed on the outer surface of the fixed cover 201. The adjustable telescopic rods 501 can be fixed at any length after extension and retraction to adjust the position of the dust collection cover 502. One end of the adjustable telescopic rod 501 is fixedly connected to the dust collection cover 502. An electromagnet 503 is fixedly embedded in one side of the inner surface of the dust collection cover 502. An air collection tube 504 is fixedly installed at the lower end of the dust collection cover 502.

[0047] In practice, the air collection pipe 504 is connected to an external filter and a fan, which generates suction at the dust collection hood 502. At the same time, the electromagnet 503 attracts the metal shavings, collecting the fallen metal shavings onto the surface of the electromagnet 503. After processing, the electromagnet 503 is de-energized, allowing the metal shavings to be discharged from the air collection pipe 504. Thus, by setting up a dust collection hood 502 on one side of the ship's stern tube and cooperating with the electromagnet 503 to attract and collect the metal shavings, the metal shavings generated by boring are easy to clean.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
