DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes the present utility model with reference to embodiments.

[0024] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the drawings of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the concept of the present utility model belongs to the scope of protection required by the present utility model.

[0026] When welding the propeller blades to the propeller, it is necessary to use a clamping structure to clamp and fix the mounting shaft cylinder 32 in the middle of the propeller. Then, the positioning structure fixes one end of the blade to fit against the outside of the mounting shaft cylinder 32, and manual welding is carried out by holding a welding gun. However, since multiple blades need to be welded, after loosening the clamping structure, the mounting shaft cylinder 32 is removed, manually flipped and repositioned, and then clamped and fixed by the clamping structure for welding. This method greatly reduces the welding efficiency.

[0027] Therefore, please refer to Figures 1-3 , the present utility model provides a ship processing welding device for welding ship propellers, including a support table 1, and two support plates 2, a support pile 3, a blade lifting and aligning structure 4, a flipping assembly, and a linkage positioning structure 6 provided on the support table 1.

[0028] Specifically, two symmetrically arranged support plates 2 are fixedly connected to the top of the support table 1. An arc-shaped support block 31 fixedly connected to the center of the top of the support table 1 by a support pile 3 is arranged between the two support plates 2. The top arc-shaped notch of the arc-shaped support block 31 is used to place the middle mounting shaft cylinder 32 of the ship propeller. A blade lifting and aligning structure 4 for facilitating the lifting and alignment of the blades is installed on the support table 1.

[0029] A flipping assembly is installed on one of the two support plates 2. The flipping assembly includes a motor 5 fixedly connected to the outer wall of one of the support plates 2. The output shaft of the motor 5 penetrates the support plate 2 and is fixedly connected with a first positioning cone 51. The motor 5 can rotate and fix the clamping-mounted shaft cylinder 32 at a fixed angle, thus facilitating the subsequent alignment of multiple blade pieces for assisting welding. The motor 5 is preferably a stepping motor.

[0030] A linkage positioning structure 6 is installed on the other support plate 2, and the linkage positioning structure is also connected to the blade lifting and aligning structure 4.

[0031] The blade lifting and alignment structure 4 includes a guide plate 41 located at the rear side of the support pile 3 and fixedly connected to the top of the support platform 1. A lifting plate 42 is provided on the outer sliding sleeve of the guide plate 41. An electric telescopic rod 45 is fixedly connected to the rear side wall of the support platform 1. The telescopic end of the electric telescopic rod 45 is connected to the bottom end of the lifting plate 42. A blade groove 43 opened on the lifting plate 42 is provided above the arc-shaped support block 31. A blade is movably inserted in the blade groove 43. A hand screw 44 is threadedly penetrated and connected on the inclined wall provided at the front end of the lifting plate 42. After the hand screw 44 is tightened, it can be pressed against the outer side of the blade.

[0032] During use, the mounting shaft cylinder 32 is placed on the arc-shaped support block 31, and the paddle blade is inserted into the paddle blade groove 43, and the paddle blade is fixed by tightening the hand screw 44. Secondly, the electric telescopic rod 45 is started and the lifting plate 42 is pulled to drive the paddle blade to descend, so that one end of the paddle blade is attached to the outer side of the mounting shaft cylinder 32 to ensure stability during welding.

[0033] Further as Figures 1-3 As shown, it is worth specifically explaining that the linkage positioning structure 6 includes a spline sleeve 61 rotatably connected to the other support plate 2, and a matching spline shaft 62 is movably installed in the mounting shaft hole of the spline sleeve 61. The spline shaft 62 is fixedly connected to a second positioning cone 63 at one end facing the first positioning cone 51, and a pressed block 64 is fixedly connected to the other end. The pressed block 64 is provided with a first inclined surface at one end away from the spline shaft 62, and a symmetrically arranged The two guide rods 65, the other ends of the two guide rods 65 are movably inserted on the other support plate 2, and the outer sides of the two guide rods 65 are sleeved with springs 66, one end of the spring 66 is fixedly connected to the outer side of the other support plate 2, and the other end is fixedly connected to the outer side of the pressed block 64, a pressing rod 67 is fixedly connected to the right side wall of the lifting plate 42, the pressing rod 67 is movably overlapped on the outer side of the pressed block 64, and the bottom end of the pressing rod 67 is provided with a second inclined surface 68 for facilitating the extrusion of the first inclined surface.

[0034] During the downward movement of the lifting plate 42, the second inclined surface 68 at the bottom end of the pressure rod 67 will squeeze the first inclined surface below in advance before one end of the blade is in contact with the outer side of the mounting shaft cylinder 32, so that the second positioning cone 63 connected to the spline shaft 62 driven by the pressure block 64 moves toward the direction of the first positioning cone 51, and the mounting shaft cylinder 32 is positioned first, and the two springs 66 are in a compressed state.

[0035] It should be noted that the telescopic length of the electric telescopic rod 45 can be manually controlled through the PLC control program, which can be achieved by existing technologies. In particular, when the lifting plate 42 disengages from a welded blade, the hand-tightening screw 44 can be loosened, and by starting the electric telescopic rod 45, the lifting plate 42 can be pushed upward. However, the height of the upward movement of the lifting plate 42 only needs to make the blade groove 43 disengage from the top of the blade. However, Figure 1 the pressing rod 67 can be moved upward by a small distance, and the pressed block 64 is still in a pressed state, so that the second positioning cone 63 and the first positioning cone 51 are still in a state of positioning the mounting shaft cylinder 32. However, at this time, the blade groove 43 on the lifting plate 42 is already above the top of the blade, which is not enough to hinder the rotation of the blade along with the mounting shaft cylinder 32. After the welded blade rotates and is fixed at a certain angle along with the mounting shaft cylinder 32, the corresponding blade can be repeatedly inserted into the blade groove 43 and fixed by tightening the hand-tightening screw 44.

[0036] When using this ship processing and welding device, first, place the mounting shaft cylinder 32 on the arc-shaped supporting block 31, insert the blade into the blade groove 43, and fix the blade by tightening the hand-tightening screw 44. Secondly, by starting the electric telescopic rod 45 and pulling the lifting plate 42 to drive the blade to descend. At the same time, the second inclined surface 68 at the bottom end of the pressing rod 67 will squeeze the lower first inclined surface, so that the second positioning cone 63 connected to the spline shaft 62 driven by the pressed block 64 moves towards the first positioning cone 51, and the mounting shaft cylinder 32 is positioned, and the two springs 66 are in a compressed state. At the same time, the lifting plate 42 continues to descend, and the bottom end of the blade is attached to the outside of the mounting shaft cylinder 32, so as to facilitate manual welding with a welding torch held by hand. After welding is completed, when it is necessary to turn over and weld another blade, the hand-tightening screw 44 can be loosened. At this time, by starting the electric telescopic rod 45, the lifting plate 42 is pushed upward. However, the height of the upward movement of the lifting plate 42 only needs to make the blade groove 43 disengage from the top of the blade. However, the second positioning cone 63 is still in a state of positioning the mounting shaft cylinder 32 between the first positioning cones 51. Then, by starting the stepping motor 5, the mounting shaft cylinder 32 is rotated and fixed at a certain angle. Finally, by repeating the above operation steps, the welding and installation of multiple blades can be realized, and the alignment angle is stable, and it is not easy to appear the phenomenon of skew angle deviation. In addition, when turning over, there is no need to disassemble and fix the mounting shaft cylinder 32, which greatly improves the welding efficiency.
