[0027] Need to explain, Figure 1 It is a perspective view of the propeller shell 90, which is axially provided with a center hole 91, and the side part is protrudingly extended with a propeller shaft 92, and the propeller shaft 92 is axially provided with a propeller shaft hole 921, and the end tooth 93 needs to be formed at the upper end circumferential edge of the center hole 91.

[0028] The propeller shell end tooth processing device of the application is designed for the structure of the propeller shell 90, the base 1 is installed on the rotary table of the machine tool 80, the propeller shell 90 is first limited to the radial position relative to the base 1 through the first positioning member 20, and then the axial position and the circumferential position relative to the base 1 are limited through the second positioning assembly 30, and finally fixed on the base 1 through the mounting assembly 10. The tool setting assembly 40 and the propeller shell 90 are fixed relative to the base 1, so the relative position of the tool setting groove 411 and the propeller shell 90 is fixed, the tool of the machine tool 80 is aligned through the tool setting groove 411, so as to ensure the accurate relative position of the tool and the propeller shell 90, and then the tool processes the end tooth 93 of the propeller shell 90, and in the processing process, the propeller shell 90 is always fixed relative to the base 1, the rotary table rotates to drive the propeller shell 90 to rotate circumferentially, so that the tool can process all the end teeth 93. The propeller shell end tooth processing device can be specifically used for assisting the propeller shell 90 to be fixed on the machine tool 80, so that the tool can cut the end tooth 93 of the propeller shell 90, and solve the problem that the end tooth 93 of the propeller shell 90 cannot be processed in the prior art.

[0029] Please refer to Figures 2 to 4 Among them, Figure 2 It is a longitudinal sectional view of the propeller shell end tooth processing device provided in the embodiments of the application cooperating with the propeller shell 90, Figure 3 It is a perspective view of the propeller shell end tooth processing device, Figure 4 It is a perspective view of the mounting assembly 10 and the first positioning member 20.

[0030] In some embodiments provided in the present application, the mounting assembly 10 comprises a plug rod 11 and a locking member 12 movably connected to the plug rod 11, the plug rod 11 is arranged to be inserted into the central hole 91 of the paddle shell 90, the locking member 12 is located above the first positioning member 20, and the longitudinal area between the locking member 12 and the first positioning member 20 is formed as an area for placing the paddle shell 90, the locking member 12 is arranged to be movable along the extension direction of the plug rod 11 to fix the paddle shell 90 in the area.

[0031] The plug rod 11 extends in the vertical direction to be coaxial with the central hole 91 of the paddle shell 90, after the plug rod 11 is inserted into the central hole 91 of the paddle shaft 92, the top end of the plug rod 11 protrudes from the paddle shell 90, and the locking member 12 locks the paddle shell 90 on the base 1 at the top end of the plug rod 11. The locking member 12 only exerts force on the top end of the paddle shell 90, and no component for fixing the paddle shell 90 is arranged on the outer side of the paddle shell 90, so as to avoid the component exerting pressure on the outer side of the paddle shell 90 and causing damage to the paddle shell 90.

[0032] Please continue to read Figures 2 to 4 In some embodiments provided in the present application, the plug rod 11 is formed with external threads, and the locking member 12 is formed with a threaded hole to be threadedly connected to the external threads.

[0033] Screwing the locking member 12 can move the locking member 12 along the extension direction of the plug rod 11, the threaded connection can stop the locking member 12 at any position of the plug rod 11, and the locking member 12 can be moved slightly in the extension direction of the plug rod 11 by accurately controlling the screwing angle of the locking member 12, so as to gradually increase the force exerted by the locking member 12 on the paddle shell 90, and avoid that the paddle shell 90 is suddenly subjected to a large extrusion force and is damaged.

[0034] The locking member 12 can be a nut and can be detached from the top end of the plug rod 11. The plug rod 11 can be a screw rod, i.e., the entire axial direction of the plug rod 11 is formed with external threads, as shown in Figure 4 The center of the first positioning member 20 is formed with a mounting hole, the bottom end of the plug rod 11 is inserted into the mounting hole, the mounting hole can be a threaded hole matched with the threaded hole of the plug rod 11, or can be a circular hole, when the mounting hole is a circular hole, the bottom end face of the plug rod 11 is formed with a protruding ring (not shown in the figure), and the mounting hole is formed with a protruding table (not shown in the figure), the plug rod 11 is inserted into the mounting hole from bottom to top until the protruding ring is clamped at the protruding table, the plug rod 11 cannot continue to move upward, and is locked by the mounting nut 23.

[0035] Please continue to read Figures 2 to 4 In some embodiments provided in the present application, the mounting assembly 10 further comprises a gasket 13 sleeved on the plug rod 11, the gasket 13 is located between the locking member 12 and the first positioning member 20, and the circumferential dimension of the gasket 13 is greater than the circumferential dimension of the locking member 12.

[0036] The gasket 13 is made of soft material or has elasticity, and is located between the locking member 12 and the paddle shell 90. The locking member 12 transmits the force to the paddle shell 90 through the gasket 13, so that the hard connection between the locking member 12 and the paddle shell 90 is avoided, and the wear of the paddle shell 90 is avoided. In addition, the gasket 13 can also buffer the vibration generated by the cutter during the processing of the end tooth 93 of the paddle shell 90, so as to protect the paddle shell 90.

[0037] The gasket 13 can be a "C" shape, and is clamped into the insertion rod 11 through the gap.

[0038] It should be noted that, before the insertion rod 11 is inserted into the center hole 91 of the paddle shell 90, in order to avoid that the locking member 12 and the gasket 13 block the paddle shell 90, the locking member 12 is detached from the insertion rod 11, and the paddle shell 90 is sleeved on the insertion rod 11 from top to bottom.

[0039] Please continue to see Figures 2 to 4 In some embodiments provided in the present application, the first positioning member 20 has an arc-shaped limiting surface 211, which is arranged to be able to fit the hole wall of the center hole 91 of the paddle shell 90, so as to limit the radial position of the paddle shell 90 relative to the base 1.

[0040] The curvature of the arc-shaped limiting surface 211 is the same as the curvature of the hole wall of the center hole 91 of the paddle shell 90, so that the two can be fitted. The arc-shaped limiting surface 211 is annular, and is fitted on the full circumferential hole wall of the center hole 91 of the paddle shell 90. Under the limiting action of the arc-shaped limiting surface 211, the paddle shell 90 cannot move along its own radial direction, that is, the radial position of the paddle shell 90 is limited, and the center positioning of the paddle shell 90 is realized.

[0041] As shown in Figure 4 The first positioning member 20 includes a coaxial outer circular ring 21 and an inner circular table 22. The outer circumferential surface of the outer circular ring 21 forms the arc-shaped limiting surface 211, and the center of the inner circular table 22 forms a mounting hole for connecting the insertion rod 11. The outer circular ring 21 is connected to the base 1 by screws and bayonets.

[0042] Please see Figure 2 , Figure 3 and Figure 5 , wherein Figure 5 is a perspective view of the second positioning assembly 30.

[0043] In some embodiments provided in the present application, the second positioning member 31 includes an insertion column 311 and a slide rod 312 coaxially connected to the insertion column 311. The insertion column 311 is arranged to be able to be inserted into the paddle shaft hole 921 of the paddle shell 90, and to be fitted to the hole wall of the paddle shaft hole 921, so as to limit the axial position and the circumferential position of the paddle shell 90 relative to the base 1. The slide rod 312 can be driven to move along its own axial direction, so as to drive the insertion column 311 to move to be inserted into or extracted from the paddle shaft hole 921 of the paddle shell 90.

[0044] The outer diameter of the insertion column 311 is the same as the hole diameter of the paddle shaft hole 921, so that the outer periphery of the insertion column 311 is unable to fit to the hole wall of the paddle shaft hole 921. Since the paddle shaft hole 921 is formed in the side of the paddle shell 90, after the insertion column 311 is inserted into the paddle shaft hole 921, the paddle shell 90 is unable to move along the axial direction of itself or rotate along the circumferential direction of itself, that is, the axial position and the circumferential position of the paddle shell 90 are simultaneously limited. The slide rod 312 is used to limit the moving direction of the insertion column 311. Before the paddle shaft 92 is sleeved on the outer ring 21 of the first positioning member 20, the insertion column 311 is also unable to be coaxial with the paddle shaft hole 921. At this time, in order to avoid that the insertion column 311 blocks the paddle shell 90 from moving from top to bottom to the outer ring 21, the slide rod 312 is driven to slide, and the insertion column 311 is driven to move in the direction away from the insertion rod 11, so as to avoid the paddle shell 90. After the paddle shell 90 is sleeved on the outer ring 21 of the first positioning member 20, at this time, the insertion column 311 is coaxial with the paddle shaft hole 921. The slide rod 312 is driven to slide, and the insertion column 311 is driven to move in the direction close to the insertion rod 11, until the insertion column 311 is inserted into the paddle shaft hole 921.

[0045] Please continue to see Figure 2 , Figure 3 and Figure 5 In some embodiments provided in the present application, the second positioning assembly 30 further comprises a limiting block 32, and the limiting block 32 has a sliding groove 321. The slide rod 312 is slidably arranged in the sliding groove 321, so as to move along the axial direction of itself relative to the sliding groove 321.

[0046] The sliding groove 321 is used to limit the sliding direction of the slide rod 312, so that the slide rod 312 always moves horizontally in the direction close to and away from the insertion rod 11, so as to ensure that the insertion column 311 is smoothly inserted into the paddle shaft hole 921 of the paddle shell 90.

[0047] In some embodiments provided in the present application, the sliding groove 321 is formed in a “U” shape with the opening facing upward. The second positioning assembly 30 further comprises a first mounting table 33 fixed on the base 1. The limiting block 32 is connected to the first mounting table 33 by screws and latches. The first mounting table 33 is used to raise the height of the limiting block 32, so as to ensure that the height of the insertion column 311 is adapted to the setting position of the paddle shaft hole 921 of the paddle shell 90, and further ensure that the insertion column 311 is smoothly inserted into the paddle shaft hole 921.

[0048] Please see Figure 2 , Figure 3 and Figure 6 In some embodiments provided in the present application, the second positioning assembly 30 further comprises a first mounting table 33 fixed on the base 1. The limiting block 32 is connected to the first mounting table 33 by screws and latches. The first mounting table 33 is used to raise the height of the limiting block 32, so as to ensure that the height of the insertion column 311 is adapted to the setting position of the paddle shaft hole 921 of the paddle shell 90, and further ensure that the insertion column 311 is smoothly inserted into the paddle shaft hole 921. Figure 6

[0049] In some embodiments provided in the present application, the tool setting assembly 40 comprises a tool setting block 41. A tool setting groove 411 is formed on the tool setting block 41. The height of the groove bottom of the tool setting groove 411 protruding from the base 1 is greater than the height of the second positioning assembly 30 protruding from the base 1. ​

[0050] Before machining the end teeth 93, the tool of the machine tool 80 needs to be aligned to ensure the accuracy of the position of the end teeth 93. The alignment block 41 is arranged on the base 1, and the relative positions of the alignment block 41, the first positioning member 20, the mounting assembly 10 and the second positioning member 31 are fixed. The design of the positions is based on the fact that, after the paddle shell 90 is mounted to the base 1, the extension direction of the alignment groove 411 can be parallel to the axial direction of the paddle shaft hole 921. After the base 1 is mounted to the rotary table of the machine tool 80, the cutting edge of the tool is inserted into the alignment groove 411 and moved along the alignment groove 411 to perform the alignment. In order to avoid the tool from touching the second positioning assembly 30 during the movement along the alignment groove 411, the bottom of the alignment groove 411 is arranged to be higher than the second positioning assembly 30, so as to avoid the second positioning assembly 30 from hindering the movement of the tool.

[0051] In the embodiment, the tool is disc-shaped, and the cutting edge is formed on the outer periphery of the tool. The alignment groove 411 is formed in a “V” shape, and the opening of the alignment groove 411 faces upward to facilitate the entry of the cutting edge of the tool. The alignment assembly 40 further comprises a second mounting table 42, and the alignment block 41 is connected to the second mounting table 42 by screws and a latch. The second mounting table 42 is used to raise the height of the alignment block 41, so as to ensure that the bottom of the alignment groove 411 is higher than the second positioning assembly 30.

[0052] Please continue to refer to Figure 2 , Figure 3 and Figure 6 In some embodiments provided in the present application, the alignment block 41 is arranged in multiple numbers, and at least two alignment blocks 41 are arranged on opposite sides of the base 1. The extension lines of the alignment grooves 411 of the two alignment blocks 41 arranged oppositely are located on the same straight line.

[0053] In the two alignment blocks 41 arranged oppositely, after the tool moves along the alignment groove 411 of one of the alignment blocks 41, the tool continues to move along the same path until the tool enters the alignment groove 411 of the other alignment block 41 and moves along the alignment groove 411, so as to ensure the accuracy of the alignment and avoid cutting deviation during the cutting process. It should be noted that, if the tool moves along the alignment groove 411 of one of the alignment blocks 41 and cannot continue to move due to the obstruction of the top end of the insertion rod 11 of the mounting assembly 10, the base 1 can be moved downward by operating the machine tool 80, so as to move the insertion rod 11 downward to avoid the tool, so that the tool can continue to move along the extension direction of the alignment groove. After the tool passes the insertion rod 11, the base 1 can be moved upward by operating the machine tool 80, so that the tool can enter the alignment groove 411 of the other alignment block 41.

[0054] In the embodiment, the alignment assembly 40 is arranged in two numbers oppositely.

[0055] Please refer to Figure 1In some embodiments provided in the application, the propeller blade shell end tooth processing device further comprises a force applying protrusion 50 arranged on the side of the base 1 to provide a force applying point for moving the base 1.

[0056] Before the blade shell 90 is mounted on the base 1, the entire propeller blade shell end tooth processing device needs to be moved to the rotary table of the machine tool 80 for installation, and after the end tooth 93 of the blade shell 90 is processed, the blade shell 90 and the entire propeller blade shell end tooth processing device need to be moved out of the machine tool 80, therefore, the force applying protrusion 50 is arranged to facilitate the connection of a carrying tool or a hoisting tool through the force applying protrusion 50.

[0057] The force applying protrusions 50 are oppositely arranged in two.
