Description

Technical Field

[0001] This invention relates to the field of irregular-shaped parts processing, and in particular to a processing apparatus for irregular-shaped ship parts. Background Technology

[0002] In the construction of ships, especially large commercial vessels, warships, and marine engineering equipment, pipeline systems are like the blood vessels of the human body, spreading throughout the ship and undertaking the task of transporting various media such as fuel, lubricating oil, seawater, fresh water, air, and hydraulic oil. In order to avoid the hull structure, other equipment, and systems, these pipelines must be designed with various complex spatial orientations, resulting in irregularly shaped pipe fittings.

[0003] Currently, in the processing of irregularly shaped pipe fittings, it is difficult for general-purpose fixtures to achieve stable and reliable clamping of irregularly curved pipes, which can easily lead to accidents in subsequent processing and damage to the workpiece. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0019] The following will refer to the appendix. Figures 1 to 6 The present invention will be described in detail with reference to the embodiments.

[0020] Overall, this invention discloses a processing device for irregularly shaped ship parts, which includes a housing 1, a receiving cover 2 disposed on the top of the housing 1, vertical plates 4 symmetrically slidably disposed on the top of the receiving cover 2, and positioning components disposed on opposite sides of the two vertical plates 4; wherein the positioning components include a mounting plate 5 connected to the vertical plate 4, a fixing plate 6 symmetrically fixedly disposed on the side wall of the mounting plate 5, and a positioning shell 9 disposed between the two fixing plates 6. The positioning shell 9 is slidably connected to a plurality of extrusion columns 902, and the fixing plate 6 is provided with a sliding groove 602, in which a slider 7 is slidably connected, and the slider 7 is connected to the positioning shell 9.

[0021] Figure 1 The workpiece indicated by part A in the middle refers to the irregularly shaped workpiece in this invention, but it is not limited to the processing of workpieces of this size.

[0022] In this embodiment, the workpiece is clamped by multiple extrusion columns 902 that are uniformly slidably connected by the positioning shells 9 on both sides. This allows for extrusion positioning from multiple directions, which can better adapt to the irregular shape of the workpiece, ensure that the workpiece is fixed in position during processing, reduce processing errors caused by inaccurate positioning, improve processing accuracy, and meet the high precision requirements of shipbuilding for parts.

[0023] In the positioning assembly, the positioning shell 9 is slidably connected to the slide groove 602 on the fixed plate 6 via the slider 7, so that the positioning shell 9 can be further adjusted in position when clamping the workpiece, ensuring that the workpiece is subjected to uniform force during processing.

[0024] In practice, based on the shape and size of the irregularly shaped ship parts to be processed, the operator symmetrically slides the vertical plates 4 on top of the receiving cover 2 to adjust the distance between the two vertical plates 4. The irregularly shaped ship parts to be processed are placed in a suitable position between the two positioning components, ensuring that the irregularly shaped parts are roughly in the center area between the two vertical plates 4. The position of the vertical plates 4 is further fine-tuned so that the mounting plates 5 on both sides are close to the irregularly shaped parts. Then, the positioning shell 9 is manually pushed, and the slider 7 slides within the groove 602 of the fixing plate 6, allowing the extrusion columns 902 to gradually extrude the irregularly shaped parts from different directions until the irregularly shaped parts are stably fixed between the multiple extrusion columns 902, achieving precise positioning. After the irregularly shaped parts are positioned, the relevant processing equipment (such as cutting equipment, drilling equipment, etc.) of the ship irregularly shaped parts processing device is started, and the irregularly shaped parts are processed according to the preset processing parameters.

[0025] As a preferred embodiment, a placement cavity 601 is formed inside the positioning shell 9. A first spring 702 is provided inside the placement cavity 601. One end of the first spring 702 is fixedly connected to the inner side wall of the placement cavity 601, and the other end is slidably fixedly connected.

[0026] The placement cavity 601 and the first spring 702 within the positioning shell 9 add an adaptive adjustment function to the entire positioning process. When the extrusion column 902 is subjected to the reaction force of the irregularly shaped part, the slider 7 slides within the placement cavity 601 and compresses the first spring 702. The first spring 702 undergoes different degrees of elastic deformation according to the magnitude of the force. This elastic deformation can provide real-time feedback and adjust the extrusion force of the extrusion column 902 on the irregularly shaped part, allowing the extrusion column 902 to more accurately target the irregular surface of the irregularly shaped part, further improving the positioning accuracy.

[0027] Based on the above configuration, the slider 7 and the positioning shell 9 are rotatably connected by a rotating shaft 701. One end of the rotating shaft 701 extends to the outside of the slider 7 and is connected to the power assembly. The power assembly includes a first motor 8, a worm 801, and a worm wheel 802. The worm wheel 802 is fixedly mounted on the end of the rotating shaft 701. The first motor 8 is fixedly mounted on the fixing plate 6. The worm 801 is fixedly mounted on the output shaft of the first motor 8. The worm wheel 802 and the worm 801 cooperate with each other.

[0028] The slider 7 and the positioning shell 9 are rotatably connected via a rotating shaft 701 and driven to rotate by a power component. This design allows the positioning shell 9 to rotate around the rotating shaft 701 at multiple angles. When processing ship-shaped parts with extremely complex shapes and multiple irregular surfaces, the operator can precisely adjust the angle of the positioning shell 9 according to the position and angle requirements of different processing surfaces of the part, thereby adjusting the extrusion direction of the extrusion column 902.

[0029] In practice, the output shaft of the first motor 8 drives the worm 801 to rotate. The worm 801 cooperates with the worm wheel 802 to transmit the rotational motion to the worm wheel 802. The worm wheel 802 drives the rotating shaft 701 to rotate, thereby causing the positioning shell 9 to rotate around the rotating shaft 701.

[0030] It should be noted that the bottom end of the extrusion column 902 extends through to the outside of the cover plate 901, and a second spring 905 is fitted inside the positioning shell 9. One end of the second spring 905 is fixedly connected to the positioning shell 9, and the other end is fixedly connected to the extrusion column 902.

[0031] In this embodiment, when dealing with irregularly shaped ship parts, the compression columns 902 at different locations will be subjected to varying degrees of compression due to the undulations of the part's surface. The second spring 905 can automatically extend and retract according to the pressure exerted on each compression column 902, allowing each compression column 902 to independently adjust the compression force on the part, thus improving the device's adaptability to various regular-shaped irregular parts.

[0032] Furthermore, the top of the extrusion column 902 is fixedly provided with an arc-shaped contact end 903, and the tail end is fixedly provided with a limiting plate 904.

[0033] The top of the extrusion column 902 is provided with an arc-shaped contact end 903, which greatly increases the contact area with the surface of the ship's irregularly shaped parts. Compared with flat contact, the arc-shaped contact surface can better adapt to the curves and undulations of the irregularly shaped parts' surface, and can fit more tightly with the irregularly shaped parts during positioning, reducing the possibility of excessive local pressure or unstable positioning caused by a small contact area.

[0034] The limiting plate 904 can prevent the extrusion column 902 from falling out of the positioning shell 9 due to excessive movement, thus avoiding equipment failure and safety accidents caused by the detachment of parts.

[0035] The receiving cover 2 is provided with an adjustment component that drives the two vertical plates 4 to move closer or further away. The adjustment component includes a screw and a second motor 303. The screw is provided with a first thread 301 and a second thread 302 with opposite spiral directions. The first thread 301 and the second thread 302 are respectively screwed to the two vertical plates 4. The second motor 303 is fixedly mounted on the receiving cover 2, and its output shaft is fixedly connected to the screw.

[0036] The adjustment assembly employs a design with a first thread 301 and a second thread 302 on the screw, each with opposite spiral directions, which are screwed onto the two vertical plates 4 respectively. This design enables the two vertical plates 4 to move synchronously and precisely closer or further apart. When the second motor 303 drives the screw to rotate, due to the opposite thread directions, the two vertical plates 4 move in opposite directions at the same speed. This allows for quick and precise adjustment of the distance between the two vertical plates 4 to accommodate irregularly shaped ship components of varying widths.

[0037] As a preferred structure, the mounting plate 5 is rotatably connected to the vertical plate 4 via a connecting shaft 401. The connecting shaft 401 extends to the outside of the vertical plate 4 and is fixedly provided with a first gear 10. The vertical plate 4 is fixedly provided with a third motor 1002. The output shaft of the third motor 1002 is fixedly connected to the second gear 1001. The first gear 10 and the second gear 1001 mesh with each other.

[0038] Mounting plate 5 is rotatably connected to vertical plate 4 via connecting shaft 401, and is driven by third motor 1002 to rotate flexibly through the meshing transmission of first gear 10 and second gear 1001. This allows the positioning assembly to finely adjust the angle of mounting plate 5 in a direction perpendicular to the plane of vertical plate 4, improving positioning accuracy and adaptability, and enhancing processing quality.

[0039] In addition, in order to meet the needs of the positioning device to adapt to the processing requirements of ship irregular parts at different height positions, in this embodiment, a lifting assembly is also provided between the housing 1 and the receiving cover 2. The lifting assembly includes a hydraulic cylinder 102 and a guide column 101. The hydraulic cylinder 102 is fixedly installed on the top of the housing 1, and its end is fixedly connected to the bottom surface of the receiving cover 2. The guide column 101 is symmetrically arranged on both sides of the hydraulic cylinder 102. Its top end is fixedly connected to the receiving cover 2, and its bottom end is slidably connected to the housing 1.

[0040] The lifting assembly raises or lowers the receiving cover 2 and the positioning assembly, making it convenient for operators to install, disassemble, and process irregularly shaped parts.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
