[0055] Aiming at the technical problems of high labor intensity, low processing efficiency and low processing precision in processing the outer surface of large workpieces by manual grinding, the present invention provides a large workpiece outer surface processing device. Figure 1 and Figure 2 The device includes a fixed frame 1, a rotating frame 2, a rotating drive mechanism 3 and a cutting mechanism 4, wherein:

[0056] The fixed frame 1 is used to be fixedly mounted on the workpiece 100 to be processed;

[0057] The rotating frame 2 is rotatably mounted on the inner side of the fixed frame 1;

[0058] The rotary drive mechanism 3 is mounted on the fixed frame 1 and is in transmission connection with the rotating frame 2 , and is configured to drive the rotating frame 2 to perform circular motion around the workpiece 100 ;

[0059] The cutting mechanism 4 is mounted on the rotating frame 2 and is used to cut the outer surface of the workpiece 100 .

[0060] Take the workpiece 100 to be processed as the stern of a ship as an example. Figure 2 As shown, when machining the stern, the fixed frame 1 is first placed over the stern and secured. The rotating frame 2 and the cutting mechanism 4 thereon are positioned between the fixed frame 1 and the stern. Next, the rotary drive mechanism 3 and the cutting mechanism 4 are activated. The rotary drive mechanism 3 drives the rotating frame 2 and the cutting mechanism 4 thereon to perform a circular motion around the workpiece 100. Simultaneously, the cutting mechanism 4 cuts the outer surface of the workpiece 100. This process enables automated machining of the outer surface of a large workpiece, such as the stern.

[0061] As described above, the processing device provided by the present application can replace manual machining of large workpieces 100, and can complete the processing of the outer surface of the large workpiece 100 without the workpiece 100 moving, thereby improving processing efficiency and processing accuracy. In addition, during the processing of the large workpiece 100, the workpiece 100 may warp due to temperature changes, and the processing device provided by the present application is bound to the processing area of ​​the workpiece 100 during the processing. Therefore, the device as a whole can be adaptively adjusted as the position and size of the workpiece 100 change, so that the device can adapt to the workpiece 100 longitudinally, ensuring that the relative position of the device and the processing area of ​​the workpiece 100 remains unchanged, thereby avoiding the occurrence of warping, deformation, displacement, etc. of the workpiece 100, which affects the processing accuracy of the workpiece 100.

[0062] Continue to refer to Figure 1 and Figure 2 The bottom of the fixed frame 1 is provided with a positioning ball head 11 for connecting with the moving device 200; and / or, the fixed frame 1 is provided with a lifting hole 12.

[0063] In the above arrangement, the mobile device 200 can be a hydraulic lift, and its upper surface is provided with a positioning structure for engaging with the positioning ball head 11 at the bottom of the fixed frame 1. When the fixed frame 1 needs to be moved, the fixed frame 1 can be hoisted onto the mobile device 200, and the mobile device 200 drives the fixed frame 1 and the rotating frame 2, rotating drive mechanism 3, and cutting mechanism 4 on the fixed frame 1 to move together, thereby facilitating the installation and removal of the fixed frame 1 and the workpiece 100.

[0064] Reference Figures 3 to 5In some embodiments, the rotary drive mechanism 3 includes a rotary drive source 31, a driving gear 32 and a driven ring gear 33, wherein the body of the rotary drive source 31 is fixedly mounted on the fixed frame 1, the power output end of the rotary drive source 31 is transmission-connected with the driving gear 32, the driving gear 32 is meshed with the driven ring gear 33, and the driven ring gear 33 is fixedly mounted on the rotating frame 2.

[0065] In this embodiment, the rotary drive source 31 is specifically a motor, the output shaft of which is connected to the drive gear 32 via a reduction gear. The rotating frame 2 has a hollow conical cylindrical structure, and the driven ring gear 33 is coaxially fixed to the end of the rotating frame 2. When machining a workpiece 100, the driven ring gear 33 and the rotating frame 2 are coaxially mounted on the workpiece 100. The rotary drive source 31 is activated and drives the drive gear 32 to rotate. The drive gear 32 drives the driven ring gear 33 and the rotating frame 2 to rotate synchronously, thereby causing the rotating frame 2 and the cutting mechanism 4 on the rotating frame 2 to perform a circular motion around the workpiece 100.

[0066] In some embodiments, the rotary drive mechanism 3 includes a bearing 34 connected between the fixed frame 1 and the rotating frame 2. In this embodiment, the bearing 34 is specifically a crossed roller bearing. The outer ring of the bearing 34 is fixedly mounted on the fixed frame 1, and the inner ring of the bearing 34 is fixedly mounted on the rotating frame 2 and fixed to the driven ring gear 33. When machining the workpiece 100, the rotary drive source 31 drives the driven ring gear 33 to rotate via the drive gear 32. The driven ring gear 33 is fixedly connected to the inner ring of the bearing 34, thereby driving the rotating frame 2 to rotate.

[0067] In some embodiments, the number of the rotation drive mechanism 3 can be two, and the two rotation drive mechanisms 3 are respectively arranged at both ends of the fixed frame 1. Figure 3 As shown, a driven gear ring 33 and a bearing 34 are respectively mounted on both axial ends of the rotating frame 2 , so that both ends of the rotating frame 2 are subjected to force, thereby improving the stability of the rotating frame 2 during the rotation process.

[0068] Optionally, each rotary drive mechanism 3 includes one or more rotary drive sources 31, and a power output end of each rotary drive source 31 is connected to a drive gear 32. The number of rotary drive sources 31 in each rotary drive mechanism 3 can be adjusted according to the overall weight of the rotary frame 2 and the cutting mechanism 4, and is not limited here.

[0069] Reference Figure 6In some embodiments, the workpiece 100 has an outer conical surface 110 that needs to be machined. Accordingly, the cutting mechanism 4 includes a conical cutting assembly 41, which includes a first axial drive source 411, a first radial drive source 412, and a conical cutting tool 413. The first axial drive source 411 and the first radial drive source 412 are configured to cooperate with each other to drive the conical cutting tool 413 to move, so as to cut the outer conical surface 110 of the workpiece 100.

[0070] In a specific embodiment, the conical cutting assembly 41 also includes a first axial slide 414, a first slide 415 and a first tool holder; the first axial slide 414 is fixedly mounted on the rotating frame 2, and the first axial drive source 411 is fixedly mounted on the first axial slide 414 (or the rotating frame 2); the first slide 415 is transmission-connected to the power output end of the first axial drive source 411, and the first slide 415 is slidingly mounted on the first axial slide 414 along the first direction, and the first radial drive source 412 is fixedly mounted on the first slide 415; the first tool holder is transmission-connected to the power output end of the first radial drive source 412, and the first tool holder is slidingly mounted on the first slide 415 along the second direction, and a conical cutting tool 413 is provided at the end of the first tool holder along the second direction and close to the workpiece 100; wherein the first direction is parallel to the inclination direction of the outer conical surface 110, and the second direction is perpendicular to the first direction.

[0071] Optionally, the first axial drive source 411 and the first radial drive source 412 are both motors. The first axial drive source 411 is connected to the first slide 415 via a screw-nut structure, while the first radial drive source 412 is connected to the first tool holder via a screw-nut structure. To improve the stability of the tool during movement, guide rail and slider structures are provided between the first axial slide 414 and the first slide 415, and between the first slide 415 and the first tool holder.

[0072] In some embodiments, the conical cutting assembly 41 further includes a first measuring probe 416 connected to the conical cutting tool 413. The first measuring probe 416 can move synchronously with the conical cutting tool 413 to measure the size of the outer conical surface 110 online to ensure the machining accuracy of the workpiece 100.

[0073] Reference Figure 7 and Figure 8 In some embodiments, the workpiece 100 has an outer cylindrical surface 120 that needs to be machined. Accordingly, the cutting mechanism 4 further includes a cylindrical surface cutting assembly 42, which includes a second axial drive source 421, a second radial drive source 422, and a cylindrical surface cutting tool 423. The second axial drive source 421 and the second radial drive source 422 are configured to cooperate with each other to drive the cylindrical surface cutting tool 423 to move, thereby cutting the outer cylindrical surface 120 of the workpiece 100.

[0074] In a specific embodiment, the cylindrical cutting assembly 42 also includes a second axial slide 424, a second slide 425 and a second tool holder; the second axial slide 424 is fixedly mounted on the rotating frame 2, and the second axial drive source 421 is fixedly mounted on the second axial slide 424 (or the rotating frame 2); the second slide 425 is transmission-connected to the power output end of the second axial drive source 421, and the second slide 425 is slidingly mounted on the second axial slide 424 along the third direction, and the second radial drive source 422 is fixedly mounted on the second slide 425; the second tool holder is transmission-connected to the power output end of the second radial drive source 422, and the second tool holder is slidingly mounted on the second slide 425 along the fourth direction, and the second tool holder is provided with an outer cylindrical cutting tool 423 along the fourth direction and close to the end of the workpiece 100; wherein, the third direction is parallel to the axis of the outer cylindrical surface 120, and the fourth direction is perpendicular to the third direction.

[0075] Optionally, the second axial drive source 421 and the second radial drive source 422 are both motors. The second axial drive source 421 is connected to the second slide 425 via a screw-nut structure, and the second radial drive source 422 is connected to the second tool holder via a screw-nut structure. To improve the stability of the tool during movement, guide rail and slider structures are provided between the second axial slide 424 and the second slide 425, and between the second slide 425 and the second tool holder.

[0076] In some embodiments, the cylindrical surface cutting assembly 42 further includes a second measuring probe 426 connected to the cylindrical surface cutting tool 423. The second measuring probe 426 can move synchronously with the cylindrical surface cutting tool 423 to measure the dimensions of the outer cylindrical surface 120 online to ensure the machining accuracy of the workpiece 100.

[0077] Continue to refer to Figure 7 and Figure 8 In some embodiments, the workpiece 100 has an outer end surface 130 that needs to be machined. Accordingly, the cutting mechanism 4 further includes an end cutting assembly 43 , which includes a third radial drive source 431 and an end cutting tool 432 . The third radial drive source 431 is configured to drive the end cutting tool 432 to perform cutting on the outer end surface 130 of the workpiece 100 .

[0078] Furthermore, to enable multi-directional feed rates for the face cutting tool 432, a third radial drive source 431 is mounted on the second slide 425. In this arrangement, the second axial drive source 421 can drive the face cutting tool 432 axially relative to the outer cylindrical surface 120, while the third radial drive source 431 can drive the face cutting tool 432 radially relative to the outer cylindrical surface 120. This arrangement not only enables multi-directional feed rates for the face cutting tool 432 but also eliminates an axial drive source, thereby reducing the manufacturing cost of the device and making the overall structure of the cutting mechanism 4 more compact.

[0079] Furthermore, in order to avoid interference between the cutting tools, the conical cutting assembly 41 and the cylindrical cutting assembly 42 are staggered along the axial direction of the rotating frame 2. Figure 3 As shown, the conical surface cutting assembly 41 and the cylindrical surface cutting assembly 42 are respectively installed on opposite sides of the rotating frame 2 in the radial direction, and the cylindrical surface cutting assembly 42 and the end surface cutting tool 432 are assembled into one body.

[0080] Reference Figure 8 The working principle of the processing device provided in the present application is as follows: the fixed frame 1 is fixedly mounted on the workpiece 100, the fixed frame 1 and the workpiece 100 are fixed, and the rotary drive mechanism 3 drives the rotating frame 2 and the cutting mechanism 4 on the rotating frame 2 to make a circular motion around the workpiece 100. At this time, the conical cutting tool 413, the cylindrical cutting tool 423 and the end face cutting tool 432 all make a circular motion around the workpiece 100; during the rotation of the tool, the conical cutting tool 413 and the cylindrical cutting tool 423 can work simultaneously, wherein the conical cutting tool 413 is driven by the first axial drive source. The outer conical surface 110 is cut by the cooperative drive of the first axial drive source 411 and the first radial drive source 412, while the cylindrical surface cutting tool 423 is cut by the cooperative drive of the second axial drive source 421 and the second radial drive source 422. After the outer conical surface 110 and the outer cylindrical surface 120 are processed, the conical surface cutting tool 413 and the cylindrical surface cutting tool 423 move radially away from the surface of the workpiece 100, and the end surface cutting tool 432 is cut by the cooperative drive of the second axial drive source 421 and the third radial drive source 431. During the processing, the first measuring probe 416 and the second measuring probe 426 detect the dimensions of the outer surface of the workpiece 100 in real time to ensure that the processing accuracy of the workpiece 100 meets the processing requirements.

[0081] Reference Figure 9The processing device provided in the present application also includes a clamping mechanism 5 installed on the fixed frame 1, and the clamping mechanism 5 includes a plurality of circumferentially arranged radial positioning structures 51 and / or a plurality of circumferentially arranged radial telescopic components 52, wherein the plurality of radial positioning structures 51 are configured to cooperate together to align and position the workpiece 100, and the plurality of radial telescopic components 52 are configured to cooperate together to radially clamp or release the workpiece 100.

[0082] Optionally, the radial positioning structures 51 and the radial telescopic components 52 can be arranged alternately along the circumferential direction, or two or more groups of radial telescopic components 52 can be provided between each two adjacent radial positioning structures 51. The specific arrangement can be adjusted according to actual positioning requirements.

[0083] Continue to refer to Figure 9 Each radial positioning structure 51 is provided with a support slope 511 on its inner side. The support slopes 511 on the multiple radial positioning structures 51 form a tapered positioning ring that matches the shape of the outer tapered surface 110 of the workpiece 100. When the fixed frame 1 is placed over the workpiece 100 and advanced axially, once the outer surface of the workpiece 100 is in contact with each of the support slopes 511, the fixed frame 1 is positioned in place. The multiple radial telescopic assemblies 52 then cooperate to clamp the workpiece 100, securing the fixed frame 1 and the workpiece 100 in a secure connection.

[0084] Reference Figure 10 and Figure 11 Each radial expansion assembly 52 includes a mounting housing 521, a positioning screw 522, and a clamping block 523. The mounting housing 521 is fixedly mounted on the fixed frame 1, the positioning screw 522 is rotatably mounted on the mounting housing 521 about its own axis, and the clamping block 523 is slidably mounted on the mounting housing 521 along the axis of the positioning screw 522 and is threadedly connected to the positioning screw 522. After the fixed frame 1 is pushed into position, the positioning screw 522 is rotated to drive the clamping block 523 to move, and the multiple clamping blocks 523 cooperate to clamp the workpiece 100.

[0085] Optionally, the adjusting screw 522 can be driven automatically or manually.

[0086] In embodiments where the positioning screws 522 are automatically driven, each radial expansion assembly 52 also includes a clamping drive source. The clamping drive source is fixed to the mounting housing 521, and its power output is in driving connection with the positioning screws 522, thereby controlling the rotation of the positioning screws 522. Each radial expansion assembly 52 also includes a proximity switch mounted on the clamping block 523, which detects whether each clamping block 523 is securely clamped.

[0087] Reference Figure 1 、 Figure 12 as well as Figure 13 The number of the clamping mechanisms 5 is two and they are respectively installed at the two ends of the fixed frame 1. The two clamping mechanisms 5 can clamp and fix the two ends of the fixed frame 1 and the workpiece 100, making the connection between the two more reliable.

[0088] It should be noted that the two clamping mechanisms 5 may not be completely the same. Figure 12 and Figure 13 As shown, the shapes of the corresponding parts in the two clamping mechanisms 5 are different, but the working principles of the corresponding parts are the same (ie, substantially the same).

[0089] In summary, during the operation of the large-scale workpiece outer surface processing device provided by the present application, the entire device is bound to the processing area of ​​the workpiece 100 by the clamping mechanism 5, and then the fixed frame 1 and the workpiece 100 are kept fixed, and the rotating frame 2 and the cutting mechanism 4 on the rotating frame 2 perform circular motion around the processing area of ​​the workpiece 100.
