Description

Technical Field

[0001] This application relates to the field of propeller assembly technology, and in particular to a propeller displacement sensing component angular verticality guarantee device. Background Technology

[0002] like Figure 1 As shown, the propeller displacement sensing assembly 100 includes a bearing 101, a bearing connector 102, a displacement rod 103, a spring seat 104, and a sensing disk 105. During assembly, firstly, the bearing 101 and the bearing connector 102 are connected as one unit. The axis of the bearing 101 is located in the vertical direction. A first connecting hole is formed on the right side of the bearing connector 102, and a second connecting hole is formed at the top, communicating with the first connecting hole. The axis of the first connecting hole is located in the horizontal direction, and the axis of the second connecting hole is located in the vertical direction. Secondly, the displacement rod 103 is connected as one unit with the spring seat 104. Then, the left end of the displacement rod 103 is inserted into the connecting hole of the bearing connector 102, and the two are press-fitted together. At this time, the left end of the displacement rod 103 enters the second connecting hole. Then, a pin hole is drilled out from the second connecting hole, and a pin is inserted into the second connecting hole and the pin hole to connect the displacement rod 103 to the bearing connector 102. Finally, the right end of the displacement rod 103 is connected to the sensing disk 105.

[0003] The top surface of the spring seat 104 is curved, and the bottom surface is flat. During assembly, it is necessary to ensure that the axis of the bearing 101 is perpendicular to the bottom surface of the spring seat 104. This is an important factor affecting the sensing signal of the induction disk 105. Since the displacement rod 103 and the bearing joint 102 are interference-fitted, and a pin hole needs to be drilled in the displacement rod 103, it is inevitable that the bearing joint 102 will be misaligned during the pressing or drilling process, causing the axis of the bearing 101 to no longer remain perpendicular to the bottom surface of the spring seat 104.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] The technical solutions of the present application will be described clearly and completely below in conjunction with embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Figures 3 to 7, describes a propeller displacement sensing assembly angular vertical guarantee device provided in the embodiments of the present application, comprising: a first positioning assembly 10, having a positioning groove 111 for part of a bearing 101 of a propeller displacement sensing assembly 100 to be placed in, a groove wall of the positioning groove 111 being in contact with the bearing 101 to position an axis of the bearing 101 to a vertical direction; a second positioning assembly 20, having a positioning surface for a bottom surface of a spring seat 104 of the propeller displacement sensing assembly 100 to be placed in, the positioning surface being horizontally arranged, the second positioning assembly 20 being arranged to be able to fix the bottom surface of the spring seat 104 to be attached to the positioning surface; a baffle 30, arranged to be able to abut a displacement rod 103 connected to the spring seat 104 to define an axial position of the displacement rod 103; and a driving assembly 40 connected to the first positioning assembly 10, the first positioning assembly 10 being able to be driven by the driving assembly 40 to move horizontally to drive a bearing joint 102 connected to the bearing 101 to interference fit with the displacement rod 103.

[0029] During assembly of the propeller displacement sensing assembly 100, first, the bearing 101 and the bearing joint 102 are assembled to form a bearing assembly, and the displacement rod 103 and the spring seat 104 are assembled to form a spring seat assembly; second, the bearing assembly is installed on the first positioning assembly 10, and the bearing 101 is abutted against the groove wall of the positioning groove 111 to position the axis of the bearing 101 to the vertical direction by the positioning groove 111, and the spring seat assembly is installed on the second positioning assembly 20, and the bottom surface of the spring seat 104 is attached to the positioning surface to position the bottom surface of the spring seat 104 to be horizontal by the positioning surface; third, the driving assembly 40 is operated to drive the first positioning assembly 10 to move by the driving assembly 40 to drive the bearing assembly to move towards the spring seat assembly to make the bearing joint 102 of the bearing assembly interference fit with the displacement rod 103 of the spring seat assembly, and the bearing joint 102 and the displacement rod 103 are fixed by using a pin; and finally, the assembled bearing assembly and spring seat assembly are taken down from the propeller displacement sensing assembly angular vertical guarantee device, and the sensing disc 105 is installed at an end of the displacement rod 103. During assembly and after assembly of the propeller displacement sensing assembly 100, the axis of the bearing 101 and the bottom surface of the spring seat 104 always remain vertical to avoid affecting the sensing signal of the sensing disc 105.

[0030] It should be noted that since the end surface of the sensing disc 105 has strong magnetism, the end surface of the sensing disc 105 must be ensured not to be damaged during assembly, and therefore, the sensing disc 105 is assembled last after the bearing assembly and the spring seat assembly are assembled.

[0031] Please refer to Figure 3 and Figure 5 , which are respectively a front view and a top view of the propeller displacement sensing assembly angular vertical guarantee device.

[0032] In some embodiments provided in this application, the propeller displacement sensing component angular verticality guarantee device further includes a base 50, and a drive component 40, a first positioning component 10, a second positioning component 20 and a baffle 30 are sequentially arranged on the base 50.

[0033] According to the installation positions of the bearing assembly and spring seat assembly in the propeller displacement sensing component 100, the relative positions of the first positioning component 10, the second positioning component 20 and the baffle 30 are set to ensure the correct installation of the propeller displacement sensing component 100.

[0034] Please refer to Figure 5 In some embodiments provided in this application, the first positioning component 10 includes a positioning block 11, a positioning groove 111 is formed on the positioning block 11 and is formed in a "V" shape, the "V" shaped groove wall of the positioning groove 111 is formed in two vertical planes, and is configured to abut against the side of the bearing 101 and form two line contacts with the bearing 101.

[0035] The sidewall of bearing 101 is arc-shaped, while the wall of positioning groove 111 is flat. When they contact each other, it is a line contact. The "V"-shaped groove wall of positioning groove 111 consists of two flat walls, each forming a line contact with bearing 101. For example... Figure 5 As shown, the center of the positioning groove 111 and the center of the bearing 101 are both located on the horizontal symmetry line of the propeller displacement sensing component 100. The included angle of the "V"-shaped groove wall of the positioning groove 111 is 90°. Through measurement, under the positioning of the positioning groove 111, the perpendicularity between the axis of the bearing 101 and the bottom surface of the spring seat 104 is 0.02.

[0036] Please refer to Figures 3 to 5 ,in, Figure 4 for Figure 3 Sectional view of AA.

[0037] In some embodiments provided in this application, the first positioning component 10 further includes a positioning pressure plate 12 and a first pad 13. The positioning pressure plate 12 is disposed opposite to the positioning block 11, and the positioning groove 111 of the positioning block 11 faces the positioning pressure plate 12. The positioning block 11 is movable relative to the base 50. The positioning pressure plate 12 has a mounting hole for the end of the displacement rod 103 to pass through the area. The first pad 13 is disposed below the positioning block 11 and the positioning pressure plate 12 and is fixed relative to the base 50. The positioning block 11, the positioning pressure plate 12 and the first pad 13 form an area for the bearing 101 and the bearing joint 102 to be accommodated.

[0038] The positioning plate 12 is used to cooperate with the positioning block 11 to fix the bearing assembly in the area between the positioning block 11 and the positioning plate 12, so as to prevent the bearing assembly from shifting under force, thereby preventing the axis of the bearing 101 in the bearing assembly from deviating from the vertical position. The first pad 13 is used to support the bottom of the bearing joint 102 so that the bearing assembly can be firmly fixed in the area between the positioning plate 12 and the positioning block 11.

[0039] The top of the first pad 13 has an arc-shaped groove to avoid the displacement rod 103 passing through the mounting hole of the positioning plate 12.

[0040] like Figure 4 As shown, it illustrates the connection between the first pad 13 and the base 50. The base 50 has a through screw hole at its bottom, and the first pad 13 also has a screw hole at its bottom. The first pad 13 is fixed to the base 50 by inserting screws into the two screw holes, so that the base 50 and the first pad 13 can be processed separately and then assembled, and the first pad 13 can be replaced.

[0041] Please refer to Figure 3 and Figure 5 In some embodiments provided in this application, a first locking screw hole is formed on the positioning block 11, and a second locking screw hole coaxial with the first locking screw hole is formed on the positioning pressure plate 12. The first positioning component 10 also includes a first locking screw 14 passing through the first locking screw hole and the second locking screw hole. The distance between the positioning block 11 and the positioning pressure plate 12 is changed by the first locking screw 14.

[0042] Before the bearing assembly is installed onto the first positioning component 10, the first locking screw 14 is tightened in the first direction to increase the distance between the positioning block 11 and the positioning pressure plate 12, facilitating the insertion and placement of the bearing assembly in the appropriate position. Then, the first locking screw 14 is tightened in the second direction to decrease the distance between the positioning block 11 and the positioning pressure plate 12, thereby fixing the bearing assembly within the area between the positioning block 11 and the positioning pressure plate 12. One of the first and second directions is clockwise, and the other is counterclockwise.

[0043] The positioning block 11 has two first locking screw holes, and the positioning plate 12 has two second locking screw holes, one coaxial with the first locking screw holes. The positioning hole is located at the center of the positioning plate 12, and the two second locking screw holes are located on both sides of the mounting hole and are equidistant from the mounting hole. Two first locking screws 14 are also provided, each of which passes through one first locking screw hole and one second locking screw hole, so as to securely clamp the bearing assembly in the area between the positioning block 11 and the positioning plate 12.

[0044] In addition, such as Figure 5As shown, the first positioning assembly 10 also includes two guide posts 15, which are fixed to the positioning block 11. The positioning plate 12 also has two guide holes, each coaxial with one of the guide posts 15. The two guide holes are located on opposite sides of the mounting hole and are equidistant from it. Each guide post 15 passes through one guide hole. During the tightening of the first locking screw 14, the positioning plate 12 can always move axially along the guide posts 15, preventing the relative position of the positioning plate 12 and the positioning block 11 from shifting.

[0045] Please refer to Figure 3 , Figures 5 to 7 ,in, Figure 6 and Figure 7 These are the left and right views of the angular verticality guarantee device for the propeller displacement sensing component.

[0046] In some embodiments provided in this application, the second positioning component 20 includes a second pad 21 fixed relative to the base 50 and a movable pressure plate 22 movably disposed above the second pad. The top surface of the second pad 21 is formed as a positioning surface and faces the movable pressure plate 22. An area for the spring seat 104 to be accommodated is formed between the movable pressure plate 22 and the second pad 21.

[0047] The second positioning component 20 is used to fix the spring seat 104. Since the displacement rod 103 is connected to the spring seat 104 to form a spring seat assembly, the displacement rod 103 is also fixed at the same time. The positioning surface of the second pad 21 is horizontal. When the bottom surface of the spring seat 104 is in contact with the positioning surface, the bottom surface of the spring seat 104 is also horizontal. Then, the movable pressure plate 22 fixes the spring seat 104 in the area between the movable pressure plate 22 and the second pad 21. At this time, during the assembly process of the bearing joint 102 and the displacement rod 103, the bottom surface of the spring seat 104 can always remain horizontal.

[0048] Please continue reading. Figure 3 , Figures 5 to 7 In some embodiments provided in this application, the side of the movable pressure plate 22 facing the second pad 21 is formed as a concave arc surface so as to fit the arc-shaped top surface of the spring seat 104.

[0049] The top surface of the spring seat 104 is a convex arc surface. In order to securely fix the spring seat 104, the bottom surface of the movable pressure plate 22 is set as a concave arc surface to increase the contact area between the movable pressure plate 22 and the spring seat 104, thereby increasing the friction between the two.

[0050] Please continue reading. Figure 3 , Figures 5 to 7In some embodiments provided in this application, a third locking screw hole is formed on the movable pressure plate 22, and the second positioning component 20 further includes a second locking screw 23 passing through the third locking screw hole. The movable pressure plate 22 can change the distance between itself and the second pad 21 by means of the second locking screw 23.

[0051] Before the spring seat assembly is installed onto the second positioning component 20, the second locking screw 23 is tightened in the first direction to increase the distance between the movable pressure plate 22 and the second pad 21, facilitating the insertion and placement of the spring seat 104 in the appropriate position. Then, the second locking screw 23 is tightened in the second direction to decrease the distance between the movable pressure plate 22 and the second pad 21, thereby fixing the spring seat 104 within the area between the movable pressure plate 22 and the second pad 21. One of the first and second directions is clockwise, and the other is counterclockwise.

[0052] The movable pressure plate 22 is arched, with horizontally protruding flat plates on both sides. Two third locking screw holes are formed on these two flat plates, and the second locking screws 23 are positioned corresponding to the two third locking screw holes to increase the stability of the spring seat 104. A circular hole coaxial with the second locking screw 23 can be formed on the base 50, with the bottom of the second locking screw 23 located within this circular hole to position it and prevent it from shifting during tightening.

[0053] Please refer to Figure 5 In some embodiments provided in this application, the side of the baffle 30 facing the second positioning component 20 is formed with a slot 31, which is configured to allow the end of the displacement rod 103 to be engaged.

[0054] The slot 31 is used to define the position of the displacement rod 103. After the end of the displacement rod 103 is placed in the slot 31, its radial position is determined accordingly, and its axial position is determined by the spring seat 104 installed in the second positioning assembly 20. That is, the displacement rod 103 is connected to the spring seat 104. When the spring seat 104 is fixed, the axial position of the displacement rod 103 is naturally fixed. When the drive assembly 40 drives the first positioning assembly 10 to move, it drives the bearing joint 102 to provide a thrust to the displacement rod 103. The baffle 30 can support the displacement rod 103 and prevent the displacement rod 103 from moving relative to the spring seat 104 due to force.

[0055] Among them, such as Figure 1 As shown, both ends of the displacement rod 103 in the spring seat 104 assembly are exposed, as... Figure 3 As shown, the left end of the displacement rod 103 is inserted into the mounting hole of the positioning pressure plate 12, and the right end is inserted into the slot 31 of the baffle 30.

[0056] like Figure 7As shown, screw holes can be formed on the side of the base 50 and / or the side of the second pad 21, and screw holes can also be formed on the side of the baffle 30. The baffle 30 can be connected and fixed to the base 50 and / or the second pad 21 by screws. This detachable connection method facilitates the separate manufacturing of each component in the propeller displacement sensing assembly, and also facilitates the disassembly and replacement of the baffle 30.

[0057] Please refer to Figure 3 and Figure 5 In some embodiments provided in this application, the drive assembly 40 includes a push plate 41 fixed relative to the base 50 and a push rod 42 connected to the push plate 41. The push plate 41 has a push screw hole, the push rod 42 has an external thread, and the push rod 42 passes through the push screw hole. The end of the push rod 42 abuts against the first positioning assembly 10. The push rod 42 can be driven to rotate and move relative to the push plate 41 to push the first positioning assembly 10 to move in the direction toward the second positioning assembly 20.

[0058] The push plate 41 is fixed relative to the base 50. The push rod 42 rotates and can move horizontally relative to the push plate 41 to push the positioning block 11 to move horizontally. This, in turn, pushes the bearing assembly horizontally through the second positioning component 20 until the bearing joint 102 and the displacement rod 103 are interference-fitted. The push rod 42 pushes the second positioning component 20 by threaded advancement, converting the circumferential force into a horizontal force, which is labor-saving and ensures the smooth movement of the second positioning component 20. The threaded engagement between the push rod 42 and the push plate 41 also guides the movement direction of the push rod 42, ensuring that the push rod 42 always moves along the axial direction of the advance screw hole.

[0059] Among them, the positioning block 11 is formed in a "T" shape, so as to Figure 5 As shown in the diagram, the right end of the push rod 42 abuts against the left end of the horizontal section of the positioning block 11, so that the positioning block 11 can be pushed to the right by the push rod 42.

[0060] Additionally, the drive assembly 40 includes a handle 43 and a guide block 44. The handle 43 is fixed to the end of the push rod 42, and the extension direction of the handle 43 is perpendicular to the extension direction of the push rod 42, allowing the push rod 42 to be rotated with minimal effort via the handle 43. The handle 43, push plate 41, and guide block 44 are arranged sequentially, and the guide block 44 has a horizontally formed through hole to allow for... Figure 5 As shown in the description, the right end of the push rod 42 is located in the through hole of the guide block 44 and does not need to contact the guide block 44. The left end of the horizontal section of the positioning block 11 is inserted into the through hole of the guide block 44 and slides with the guide block 44 to ensure that the positioning block 11 can move along the axial direction of the through hole, so as to avoid the bearing 101 on the first positioning component 10 from shifting position during the movement of the first positioning component 10.

[0061] like Figure 3As shown, a through screw hole is formed at the bottom of the base 50, and a through screw hole is also formed at the top of the guide block 44. The guide block 44 is fixed to the base 50 by inserting screws into the two screw holes, so that the base 50 and the guide block 44 can be processed separately and then assembled, and the guide block 44 can be replaced.

[0062] like Figure 6 As shown, the guide block 44 can have screw holes on its side, and the push plate 41 can also have screw holes on its side. The push plate 41 can be connected and fixed to the guide block 44 by screws. This detachable connection method facilitates the separate manufacturing of each component in the propeller displacement sensing assembly, and also facilitates the disassembly and replacement of the push plate 41.
