Description

Technical Field

[0001] This utility model relates to the field of equipment technology used in shipbuilding engineering, specifically a steel structure cutting device for shipbuilding engineering. Background Technology

[0002] In existing shipbuilding engineering, steel structure cutting equipment is a very common and frequently used tool, mainly used for some rigid structures, such as steel pipes and lamps, which all require cutting. There are many existing technologies for steel structure cutting equipment.

[0003] For example, the "Cutting Device for Steel Structures" disclosed in Publication No. CN118989661A includes a cutting platform, a conveying component, a position adjustment component, a clamping and positioning component, a dust extraction component, and a cutting component. The clamping and positioning component clamps the conveyed steel plate, and the dust extraction component removes dust during the cutting process. Compared to existing technologies, this application, through the clamping and positioning component, can automatically clamp the placed steel pipe during the rotating conveying process, reducing the time spent by workers manually operating the clamping equipment. The dust extraction component ensures that the smoke and dust generated during cutting are filtered by a filter plate. The filter scraper cleans the filter plate as the clamping and positioning component moves. Harmful gases generated during cutting are treated by a purification chamber, preventing them from escaping into the air and affecting the health of workers.

[0004] For example, the "Steel Structure Cutting Device" disclosed in Publication No. CN118976968A includes a base plate, a clamping and flipping unit, a feeding and lifting unit, and a positioning unit. The clamping and flipping unit comprises a longitudinal slide, a hydraulic cylinder, a motor mounting box, a U-shaped clamp, and an electromagnetic chuck. This invention features a reliable feeding and lifting unit that assists workers in loading materials, reducing their effort. It also has a reliable clamping and flipping unit that clamps the steel plate workpiece from both the front and rear sides, preventing displacement during cutting and ensuring cutting accuracy. In addition to effective clamping and fixing, it can also flip and rotate the steel plate workpiece, facilitating repositioning. Furthermore, it has a reliable positioning unit that effectively positions the steel plate workpiece to the left, allowing for position calibration before cutting and ensuring the accuracy of subsequent cutting processes.

[0005] The above technical solutions all solve the problem of steel structure cutting through the designed mechanical structure. In actual use, steel structure cutting, especially steel pipe cutting, is mostly achieved by using horizontally set fixed fixtures. Horizontally set fixtures occupy a large space, especially for longer steel pipes, which require a large horizontal area, and have certain drawbacks.

[0006] In addition, in the existing technology, when steel pipes are cut, the cut part and the remaining part cannot be guaranteed to be fixed when separated. For example, the cut part may fall off, or the remaining part may fall off, which may cause serious safety accidents. The structural design is not reasonable enough.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a steel structure cutting device for marine engineering with a reasonable structure and improved installation coefficient. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a steel structure cutting device for marine engineering; the technical solution is as follows:

[0009] A steel structure cutting device for marine engineering includes a worktable with a rotating mechanism at its center. A rotary table is mounted on the main shaft of the rotating mechanism and rotates accordingly under the drive of the rotating mechanism. A double-headed lead screw motor is also embedded in the center of the rotary table. Both ends of the double-headed lead screw motor are provided with main shaft lead screws, and lead screw seats are mounted on both sides of the main shaft lead screws. Pressure blocks are also mounted on the lead screw seats. The thread direction on the main shaft lead screws on both sides is set accordingly, so that when the double-headed lead screw motor is turned on, it drives the pressure blocks on both sides to move inward or outward simultaneously.

[0010] Pushing mechanisms are installed on both sides of the worktable. Movable seats are installed on the main shafts of both pushing mechanisms, and cutting motors are installed on the movable seats. The cutting motors are placed vertically and cutting blades are installed on them. The cutting blades on both sides are arranged horizontally. Under the action of the pushing mechanisms, the cutting blades on both sides cut the steel pipes placed on the rotating table and fixed by pressure blocks.

[0011] Furthermore, the pressure blocks on both sides of the rotating platform are designed with an arc-shaped structure. When the steel pipe is placed on the worktable, the pressure blocks on both sides are fitted inside. After the pressure blocks on both sides move outward, the ends of the steel pipe are fixed.

[0012] Furthermore, a clearance groove is provided at the outer end face of the pressure block. The upper part of the clearance groove is set as an upper pressure block, and the lower part is set as a lower pressure block, so that the pressure block as a whole has a vertical "concave" structure.

[0013] The position of the clearance groove corresponds to the position of the outer cutting blade. When the cutting blade cuts the steel pipe, the cutting blade enters the clearance groove. The lower part of the cut steel pipe is pressed and fixed by the lower pressure block, and the upper part is pressed and fixed by the upper pressure block, so that the upper cut steel pipe will not fall off.

[0014] Furthermore, the rotary table is provided with track grooves on both sides, and the lead screw seats on both sides are correspondingly embedded in the track grooves. When the double-headed lead screw motor is turned on, the lead screw seats move in the track grooves on both sides.

[0015] Furthermore, bearing assemblies are provided on both sides of the rotary table, and the main spindle screws on both sides of the double-headed screw motor are correspondingly mounted on the bearing assemblies.

[0016] Furthermore, the worktable is provided with limit grooves on both sides, and the lower end of the movable seat is provided with a limit block, which is embedded in the limit groove.

[0017] Furthermore, a protective frame is provided on the movable seat, and the cutting blade is correspondingly placed inside the protective frame; the pushing mechanisms on both sides of the worktable move synchronously.

[0018] Beneficial effects: This utility model has the following beneficial effects:

[0019] 1) In this device, the steel pipe is placed vertically. During the actual cutting, it is fixed by the inner pressure block. Cutting the steel pipe vertically can save a lot of space. Cutting can be completed in a narrow vertical space. Compared with the traditional horizontally placed cutting device, it can save a lot of space and has a reasonable structure.

[0020] 2) In this device, the steel pipe is fixed by the inner pressure block. This device uses a double-headed screw motor to realize the synchronous movement of the pressure blocks on both sides, which can realize synchronous inward movement or synchronous outward movement, with precise control, to achieve the fixed and tightened steel pipe.

[0021] 3) In this device, the steel pipe is cut by the outer pushing mechanism driving the cutting blade, and with the cooperation of the rotary table, it can achieve rotary cutting, making the whole cutting process smoother and more reasonable.

[0022] 4) This device is specifically designed with a pressure block structure and a clearance groove on the outer end face. An upper pressure block is set on the upper side and a lower pressure block is set on the lower side. After the cutting blade cuts the steel pipe, the cutting blade enters the clearance groove accordingly. The upper part of the cut steel pipe is pressed and fixed by the upper pressure block, and the lower part is pressed and fixed by the lower pressure block. The cut steel pipe will not fall off. The overall structure is very reasonable and increases the safety of the overall structure. Attached Figure Description

[0028] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a steel structure cutting device for marine engineering includes a worktable 1. A rotating mechanism 2 is set at the middle position of the worktable 1. A rotary table 3 is mounted on the main shaft of the rotating mechanism 2. The rotary table 3 rotates accordingly under the drive of the rotating mechanism 2. A double-headed lead screw motor 4 is also embedded at the middle position of the rotary table 3. Both ends of the double-headed lead screw motor 4 are provided with main shaft lead screws 5. Lead screw seats 14 are also installed on both sides of the main shaft lead screws 5. Pressure blocks 6 are also installed on the lead screw seats 14. The thread direction on the main shaft lead screws 5 on both sides is set accordingly, so that when the double-headed lead screw motor 4 is turned on, it drives the pressure blocks 6 on both sides to move inward or outward at the same time.

[0030] Pushing mechanisms 7 are installed on both sides of the worktable 1. Movable seats 8 are installed on the main shaft of the pushing mechanisms 7 on both sides. Cutting motors 9 are installed on the movable seats 8. The cutting motors 9 are placed vertically and cutting blades 10 are installed on the cutting motors 9. The cutting blades 10 on both sides are arranged horizontally. The cutting blades 10 on both sides cut the steel pipes 11 placed on the rotary table 3 and fixed by the pressure block 6 under the action of the pushing mechanism 7.

[0031] The pressure blocks 6 on both sides of the rotary table 3 are both designed with an arc-shaped structure. When the steel pipe 11 is placed on the worktable 1, the pressure blocks 6 on both sides are fitted inside. After the pressure blocks 6 on both sides move outward, the ends of the steel pipe 11 are fixed.

[0032] A clearance groove 12 is also provided at the outer end face of the pressure block 6. The upper part of the clearance groove 12 is set as the upper pressure block 61, and the lower part is set as the lower pressure block 62, so that the pressure block 6 has a vertical "concave" structure.

[0033] The position of the clearance groove 12 corresponds to the position of the outer cutting blade 10. When the cutting blade 10 cuts the steel pipe 11, the cutting blade 10 enters the clearance groove 12. The lower part of the cut steel pipe 11 is pressed and fixed by the lower pressure block 62, and the upper part is pressed and fixed by the upper pressure block 61, so that the upper cut steel pipe 11 will not fall off.

[0034] The rotary table 3 is also provided with track grooves 13 on both sides, and the lead screw seats 14 on both sides are correspondingly embedded in the track grooves 13. When the double-headed lead screw motor 4 is turned on, the lead screw seats 14 move in the track grooves 13 on both sides.

[0035] Bearing assemblies 15 are also provided on both sides of the rotary table 3, and the main spindle screws 5 on both sides of the double-headed screw motor 4 are correspondingly installed on the bearing assemblies 15.

[0036] Limiting grooves 16 are provided on both sides of the worktable 1, and limiting blocks 17 are provided at the lower end of the movable seat 8. The limiting blocks 17 are embedded in the limiting grooves 16. A protective frame 18 is provided on the movable seat 8, and the cutting blade 10 is correspondingly placed in the protective frame 18. The pushing mechanisms 7 on both sides of the worktable 1 move synchronously.

[0037] The specific working process of this device is as follows: First, the pressure blocks on both sides are adjusted to retract inward simultaneously by the double-headed screw motor. Then, the steel pipe to be cut is placed on the rotating table, and the pressure blocks on both sides are fitted into the inside of the steel pipe. After that, the double-headed screw motor is controlled to make the pressure blocks move outward simultaneously. By expanding outward, the pressure blocks are pressed tightly into the inside of the steel pipe, thereby fixing the steel pipe. This structure can be adapted to most steel pipes with different inner diameters and is easy to use.

[0038] Then, the rotating mechanism is activated, causing the entire rotating table to rotate, which in turn causes the steel pipe that has been fixed on the rotating table to rotate. After that, the pushing mechanisms on both sides of the worktable are controlled to move the cutting blades towards the center. The cutting motor is then turned on, causing the cutting blades to rotate and cut the steel pipe. The cutting is achieved while the steel pipe is rotating.

[0039] After the cutting blade cuts the steel pipe, it moves inward into the clearance groove of the pressure block, and the steel pipe is cut accordingly. The pressure block is specifically designed with a vertical "concave" structure. An upper pressure block is set on the upper side of the clearance groove, and a lower pressure block is set on the lower side. Even after the steel pipe is cut, the lower part of the cut steel pipe is pressed and fixed by the lower pressure block, and the upper part of the cut steel pipe is pressed and fixed by the upper pressure block. The upper part of the cut steel pipe will not fall off because of the cutting. Instead, it is stabilized by the upper pressure block. The structure is very reasonable. After that, the pressure block is retracted, and the cut steel pipe can be removed.

[0040] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
