[0002] A marine intermediate shaft refers to the axis connecting the main engine and the propeller, usually located inside the hull.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Refer to the instruction manual Figure 1-9 , a marine intermediate shaft processing device according to an embodiment of the present invention, such as Figure 1 As shown, it includes a main body mechanism 1, and shaft limiting mechanisms 2 are fixedly installed at both ends of the main body mechanism 1;

[0033] A steering limit mechanism 3 is slidably installed inside the main body mechanism 1, and a plurality of grinding mechanisms 4 are fixedly installed inside the steering limit mechanism 3;

[0034] Reference Figure 3 As shown, the steering limit mechanism 3 includes a second limit sleeve 31, one side of the second limit sleeve 31 is rotatably connected to a third limit sleeve 32, and one side of the third limit sleeve 32 is fixedly connected to a driving component for driving it to rotate. Figure 6 and Figure 8 As shown, the grinding mechanism 4 includes a plurality of positioning blocks 41 fixedly mounted on the inner wall of the third limiting sleeve 32, and the inner walls of the plurality of positioning blocks 41 are rotatably mounted with a first pressing frame 42 and a second pressing frame 43 arranged in a mutually crossed state, and an anti-slip slider 44 is slidably mounted at the position where the first pressing frame 42 and the second pressing frame 43 cross each other, Fig. 9 As shown, the bottoms of the first pressing frame 42 and the second pressing frame 43 are both rotatably connected to a counterweight connection seat 45, and a pressure roller 46 is rotatably installed at the bottom of the counterweight connection seat 45. Figure 7As shown, a plurality of hydraulic telescopic rods 410 are fixedly mounted on the inner wall of the third limiting sleeve 32, and a second connecting frame 411 is fixedly mounted on one end of each of the plurality of hydraulic telescopic rods 410, an electric roller 412 is rotatably mounted on one side of the second connecting frame 411, and a polishing belt 413 is wound around the outer wall of the electric roller 412, wherein the polishing belt 413 is made of alumina fiber cloth. The polishing belt of this material has good cutting performance and wear resistance, and is suitable for polishing metal materials such as carbon steel, stainless steel and special alloys, and can be bent according to the curved surface shape of the marine intermediate shaft. It can also provide higher polishing efficiency and consistent surface quality, which is more convenient for practical use. At the same time, the pressure roller 46 is pressed on the outer wall of the polishing belt 413 near the third limiting sleeve 32 under normal conditions. When in use, the polishing belt 413 is pressed downward to make it contact and fit with the outer wall of the marine intermediate shaft, so that the polishing belt 413 moves on the outer wall of the marine intermediate shaft for polishing when the electric roller 412 rotates. Under normal conditions, every two electric rollers 412 and one polishing belt 413 are set as a set of polishing components, and each positioning block 41 is set at each The vertical centerline position of the polishing assembly is set, so that when the pressure roller 46 and the telescopic pressure holding assembly 48 arranged at the bottom of the first pressure frame 42 and the second pressure frame 43 press the polishing belt 413 to contact the outer wall of the marine intermediate shaft, the force position of the polishing belt 413 is at its centerline position, so that the overall force of the polishing belt 413 is uniform. When in use, the pressure roller 46 at the bottom of the first pressure frame 42 and the second pressure frame 43 preferentially presses the polishing belt 413 to contact the outer wall of the marine intermediate shaft, and presses the pressure roller 46 according to the shape of the outer wall of the marine intermediate shaft. The purpose is to enable the pressure rollers 46 arranged at the bottom of the first pressure frame 42 and the second pressure frame 43 to produce different ranges of pressure corresponding to the shape of the outer wall of the marine intermediate shaft when they come into contact with the outer wall of the marine intermediate shaft limited inside the outer protective frame 101, and then enable the first pressure frame 42 and the second pressure frame 43 to be deflected and adjusted respectively, so that the pressure rollers 46 arranged at the bottom of the two can correspond to different positions of the outer wall of the marine intermediate shaft respectively, thereby adapting to the fitting of different contour parts of the outer wall of the marine intermediate shaft and improving the uniformity of polishing.

[0035] At the same time, multiple positioning blocks 41, first pressure frames 42 and second pressure frames 43 are arranged in a one-to-one correspondence, and multiple positioning blocks 41 and the first pressure frames 42 and the second pressure frames 43 are arranged in a ring-shaped and equidistant state around the inner circumferential surface of the third limiting sleeve 32. The purpose of such arrangement is that the pressure rollers 46 corresponding to the bottom of the multiple first pressure frames 42 and the second pressure frames 43 can be in contact with the polishing belt 413 and the marine intermediate shaft. The different positions of the outer wall of the marine intermediate shaft can be uniformly polished simultaneously, thereby improving the processing efficiency of the device for the marine intermediate shaft, and being able to perform adaptive adjustment at multiple different positions of the outer wall of the marine intermediate shaft. Therefore, for the marine intermediate shaft with complex curved surfaces or large changes in internal and external contours, the device can completely cover and evenly polish it, avoiding the problem that the traditional method can only be applied to relatively simple surface shapes, cannot completely cover and evenly polish, and then leads to low local smoothness.

[0036] Further, see Fig. 9As shown, a supporting rod 47 is fixedly installed on one side of the counterweight connection seat 45, and a telescopic pressing component 48 perpendicular to the supporting rod 47 is fixedly installed on the outer wall of the supporting rod 47, and a controller 49 electrically connected to the telescopic pressing component 48 is fixedly installed on the bottom of the supporting rod 47. When in use, the telescopic pressing component 48 is synchronously plugged into the inside of the polishing belt 413 to limit the inner wall of the polishing belt 413 close to the center direction of the third limiting sleeve 32. The telescopic pressing component 48 is composed of multiple sections of telescopic rods connected together. Under normal conditions, The multiple telescopic rods are mutually contracted to the shortest state and extend into the interior of the polishing belt 413, and the outer walls of the multiple telescopic rods are fixedly installed with pressure sensing elements electrically connected to the controller 49. When the telescopic pressing assembly 48 horizontally extends into the interior of the polishing belt 413 and presses on the outer wall of the marine intermediate shaft, the telescopic pressing assembly 48 is first started to extend, so that the multiple pressure sensing elements arranged on the telescopic pressing assembly 48 are in contact with the outer wall of the marine intermediate shaft, and the force value generated by the contact is fed back to the controller. If the pressure detected by a certain sensor is larger or smaller, it means that the corresponding telescopic rod is subjected to a larger or smaller force, and the outer wall contour of the marine intermediate shaft in this section of the surface changes and is no longer a traditional columnar shape. At this time, the controller 49 controls the telescopic pressing assembly 48 to shrink and adjust, so that the multiple pressure sensing elements on the telescopic pressing assembly 48 are subjected to uniform force, so as to keep the polishing belt 413 limited by the telescopic pressing assembly 48 completely fitted on the outer wall of the marine intermediate shaft. When the contour of the marine intermediate shaft changes from thin to thick, the telescopic pressing assembly 48 arranged at the bottom of the first pressing frame 42 and the second pressing frame 43 respectively completely fits the polishing belt 413 on the outer wall of the marine intermediate shaft. According to the change of the contour of the area segment, the polishing belt 413 automatically follows the shape of the outer wall of the marine intermediate shaft to deform and fit at the connection position between the contour part and the normal shaft body, so that the polishing belt 413 can synchronously fit and grind the side position of the contour during the grinding and polishing process, thereby improving the polishing fineness of the device.

[0037] Among them, refer to Figure 8As shown, a second telescopic spring 420 fixedly connected to the positioning block 41 is fixedly installed on the top of the anti-slip slide block 44, and a fixing plate 417 rotatably connected to the first pressure frame 42 is fixedly installed on both sides of the positioning block 41, and a first gear plate 418 fixedly connected to the first pressure frame 42 is rotatably installed on one side of the fixing plate 417, and the outer wall of the first gear plate 418 is meshed with a second gear plate 419 rotatably connected to the fixing plate 417. The purpose of this arrangement is to increase the deflection resistance of the first pressure frame 42, so that the pressure rollers 46 and the telescopic holding assembly 48 at the bottom of the first pressure frame 42 and the second pressure frame 43 are preferentially pressed and contacted with the outer wall of the ship intermediate shaft. When deflection adjustment occurs, the first pressure frame 42 can remain fixed after deflection, and then synchronously drive the second pressure frame 43 to remain fixed, so that the corresponding pressure rollers 46 and the telescopic holding assembly 48 can stably fit and limit on the outer wall of the ship intermediate shaft. At the same time, referring to Figure 7 As shown, a plurality of limit frames 414 are fixedly installed on both sides of the third limit sleeve 32, and a guide block 415 rotatably connected to the electric roller 412 is slidably installed inside the plurality of limit frames 414, and a first telescopic spring 416 is fixedly installed between the guide block 415 and the limit frame 414. The purpose of such a setting is to make the first pressing frame 42 and the second pressing frame 43 deflect and adjust to press the center line position of the polishing belt 413, according to the different deflection angles of the first pressing frame 42 and the second pressing frame 43, The straight-line distance between the center line position of the polishing belt 413 and the inner wall of the third limiting sleeve 32 changes synchronously, and then the guide block 415 drives the electric roller 412 to follow the hydraulic telescopic rod 410 to adjust and shrink inside the limiting frame 414. The force on both sides of the electric roller 412 can be more uniform and symmetrical, thereby keeping the polishing belt 413 always in a taut state and arranged inside the third limiting sleeve 32. Then, when the electric roller 412 is started to drive the polishing belt 413 to rotate and polish, it can better contact the outer wall of the marine intermediate shaft.

[0038] Further, combined with Figure 2-3As shown, the main mechanism 1 includes an outer protective frame 101 arranged on the outer wall of the second limiting sleeve 31, an electric slide 102 is fixedly installed on the top of the outer protective frame 101, and an electric slider 103 fixedly connected to the second limiting sleeve 31 is slidably installed on the bottom of the electric slide 102, and a plurality of auxiliary slide bars 104 slidably connected to the second limiting sleeve 31 are fixedly installed in the inner cavity of the outer protective frame 101. The purpose of such a setting is to stably limit the second limiting sleeve 31 by means of a plurality of auxiliary slide bars 104, and at the same time, combined with the setting of the electric slide 102 and the electric slider 103, the second limiting sleeve 31 drives the third limiting sleeve 32 and the grinding mechanism 4 as a whole to perform translational movement in the inner cavity of the outer protective frame 101, so that the grinding mechanism 4 can perform grinding processing in sequence in the horizontal range of the marine intermediate shaft limited in the inner cavity of the outer protective frame 101. At the same time, referring to Figure 5 and Figure 2-3 As shown, the driving assembly includes an outer gear ring 33 fixedly connected to one side of the third limiting sleeve 32, and balance frames 34 slidably connected to the auxiliary sliding bar 104 are fixedly installed on both sides of the second limiting sleeve 31, and an electric gear 35 meshing with the outer gear ring 33 is rotatably installed on the top of the balance frame 34, wherein the two balance frames 34 are synchronously slidably installed on the outer wall of the auxiliary sliding bar 104, so that the two sides of the second limiting sleeve 31 can be evenly stressed and move more stably, and in actual use, by stably supporting the electric gear 35, when the electric gear 35 is started to rotate, it can stably drive the outer gear ring 33 meshing with it and synchronously drive the third limiting sleeve 32 to rotate as a whole on one side of the second limiting sleeve 31, so that the grinding mechanism 4 set inside the third limiting sleeve 32 can synchronously rotate on the outer circumferential surface of the marine intermediate shaft to perform uniform grinding.

[0039] Further, combined with Figure 4As shown, the shaft limiting mechanism 2 includes a first limiting sleeve 21 fixedly installed at both ends of the outer protective frame 101, and two support rods 22 arranged in a horizontal state are slidably installed inside the first limiting sleeve 21, and one end of the two support rods 22 extending into the first limiting sleeve 21 is fixedly installed with a clamping block 23, and the ends of the two support rods 22 away from the clamping block 23 are fixedly connected with a first connecting frame 25 arranged vertically therewith, and two threaded screws 24 are rotatably installed at the bottom of the outer protective frame 101, and the two threaded screws 24 are arranged in a fixed connection state, and the thread directions of the outer walls of the two threaded screws 24 are arranged in opposite states, and the two first connecting frames 25 are respectively threadedly connected to the outer walls of the threaded screws 24, and the purpose of such a setting is that when the two threaded screws 24 rotate synchronously, the two first connecting frames 25 can synchronously move in opposite directions on the threaded screws 24, and then the two support rods 22 can synchronously slide inside the first limiting sleeve 21 , so that the distance between the two clamping blocks 23 can be adjusted, and then in actual use, by sequentially passing the marine intermediate shaft through the first limiting sleeve 21 and the third limiting sleeve 32, and by making the distance between the two clamping blocks 23 close, until the two clamping blocks 23 are fitted and limited on the outer wall of the marine intermediate shaft, the marine intermediate shaft can be limited and clamped, wherein the side of the clamping block 23 close to the center point of the first limiting sleeve 21 is set in a "<" shape, and the purpose of such setting is that when the two relative clamping blocks 23 are synchronously limited on the outer wall of the marine intermediate shaft, the marine intermediate shaft can be automatically centered and limited, so that the center of the marine intermediate shaft and the center of the third limiting sleeve 32 are kept at the same center, and then when the third limiting sleeve 32 is horizontally displaced on the outer wall of the marine intermediate shaft, the multiple grinding mechanisms 4 maintain a uniform and symmetrical state when contacting the normal columnar range of the outer wall of the marine intermediate shaft, and then when contacting the contour change part, the adaptive adjustment is smoother.

[0040] Further, see Figure 5-6 As shown, multiple dust collecting heads 421 are fixedly installed on both sides of the third limiting sleeve 32, multiple vacuum cleaner bodies 422 are fixedly installed on the outer wall of the third limiting sleeve 32, and dust suction pipes 423 connected with the dust collecting heads 421 are fixedly installed on the outer walls of the vacuum cleaner bodies 422, wherein every two dust collecting heads 421 and a vacuum cleaner body 422 are arranged as a group, and the two dust collecting heads 421 arranged in each group are arranged in a symmetrical state with respect to the vertical center line of the third limiting sleeve 32. The purpose of such arrangement is that during the grinding process, by starting the vacuum cleaner body 422, the dust collecting heads 421 on both sides of the third limiting sleeve 32 can suck away the debris generated during the grinding of the polishing belt 413.
