Description

Technical Field

[0001] This invention relates to the field of engine assembly, and in particular to a hydraulic thruster propulsion position monitoring mechanism, thruster, and method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Hydraulic thruster: A device that uses high-pressure hydraulic oil as a power source, expands the bushing with high-pressure hydraulic oil, and simultaneously uses a low-pressure hydraulic cylinder to axially propel the bushing, thus meeting the fitting requirements of the shaft and bushing.

[0004] When assembling large-bore engines, hydraulic propulsion is often used to assemble hubs or shock absorbers to transmit large axial loads. Due to the limitations of the propulsion structure, the propulsion status cannot be directly observed, which has a certain impact on the assembly consistency of this process.

[0005] Currently, in order to achieve observation, displacement sensors are installed inside the hydraulic thruster, and the position is monitored in real time through the electronic control system. However, the inventors found that due to the influence of product processing differences and electronic control system errors, the starting position of the displacement sensor is different each time it is assembled, making it impossible to accurately locate the specific assembly position. Moreover, the system is complex and costly. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a hydraulic thruster propulsion position monitoring mechanism that provides accurate feedback on the thruster's propulsion position, thereby improving product assembly consistency.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] A hydraulic thruster propulsion position monitoring mechanism includes a transmission element installed radially on the assembly. One end of the transmission element extends into the axial process hole of the assembly. One end of the transmission element at the axial process hole contacts a guide element. An elastic element is provided at the other end of the transmission element. The end of the elastic element away from the transmission element is limited. The transmission element is connected to a position feedback column. The position feedback column is installed at the axial opening of the assembly. When the assembly shaft moves relative to the assembly, it contacts the guide element and thereby drives the position feedback column to move radially.

[0009] As described above, in a hydraulic thruster propulsion position monitoring mechanism, a first inclined surface is provided at the end of the transmission member that contacts the guide member, and a second inclined surface is provided at the end of the guide member that contacts the transmission member, with the first inclined surface and the second inclined surface cooperating with each other.

[0010] As described above, a hydraulic thruster propulsion position monitoring mechanism includes a guide member comprising a first section and a second section, the first section being connected to the second section, the end of the first section near the assembly shaft being a hemispherical surface, and the second section having a second inclined surface on the side away from the first section, the first section having a set length, and the width or diameter of the first section being less than the maximum width or maximum diameter of the second section.

[0011] In the hydraulic thruster propulsion position monitoring mechanism described above, the outer diameter or width of the section of the conductive member closest to the guide member is smaller than the outer diameter or width of the middle section and the other section.

[0012] As described above, in a hydraulic thruster propulsion position monitoring mechanism, the guide member and the device are in sliding engagement.

[0013] The guide component has a protrusion on its bottom side and a sliding groove on its assembly. Under the action of the assembly shaft, the protrusion of the guide component is pushed to move along the sliding groove.

[0014] As described above, in a hydraulic thruster propulsion position monitoring mechanism, the position feedback column is T-shaped, and the width or diameter of the position feedback column is smaller than the width or diameter of the axial opening, so as to ensure that the position feedback column moves along the radial direction of the assembly at the axial opening.

[0015] As described above, in a hydraulic thruster propulsion position monitoring mechanism, the transmission component is installed at the radial opening of the assembly, and from the outside to the inside, the adjusting bolt, the elastic component, and the transmission component are sequentially arranged in the radial opening.

[0016] As described above, in a hydraulic thruster propulsion position monitoring mechanism, the elastic element is a spring, and one end of the spring is fitted onto the threaded section of an adjusting bolt.

[0017] The position feedback column is perpendicularly connected to the conductive element;

[0018] A process hole plug is provided at the axial process hole.

[0019] Secondly, the present invention also provides a hydraulic thruster, including a thruster connected to a pull rod, a clamping sleeve arranged circumferentially on the pull rod, the clamping sleeve being connected to an assembly, an assembly shaft being provided at an opening in the middle of the assembly, one end of the pull rod being connected to the assembly shaft, a hydraulic thruster thrust position monitoring mechanism being provided at the assembly, and the assembly being provided with an oil hole and a dynamic balance counterweight hole.

[0020] Thirdly, the present invention also provides a method for judging the assembly status of a large-bore engine, employing the aforementioned hydraulic thruster propulsion position monitoring mechanism, including the following:

[0021] The assembly is equipped with an axial process hole, and a guide is provided at the axial process hole, with one end of the guide located outside the axial process hole;

[0022] The assembly is equipped with a radial opening, and a conductive element is installed at the radial opening. One end of the conductive element extends into the axial process hole and contacts the guide element.

[0023] The equipment is equipped with an axial opening, and a position feedback column is installed at the axial opening. The position feedback column is connected to the transmission component.

[0024] Install the assembly shaft at the assembly assembly point, and hydraulic oil enters the oil hole of the assembly assembly. Operate the pusher to make the pull rod axially displaced, which pushes the assembly assembly to move, so that the assembly assembly and the assembly shaft have relative displacement.

[0025] When the assembly shaft moves and contacts the guide component, the guide component pushes the transmission component to move radially, which in turn drives the position feedback column to move radially. The operator judges the assembly status of the assembly and the assembly shaft based on the displacement of the position feedback column.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1) Based on the characteristics of the hydraulic thruster propulsion structure and the relative installation position of the thruster and the propelled parts, this invention incorporates a monitoring mechanism for mechanical feedback of the propulsion status within the propelled parts. This allows for real-time observation of the propulsion status and precise positioning of the specific assembly position. The invention is simple in structure, easy to operate, and reliable in performance. It is convenient to operate, not only improving assembly efficiency but also avoiding irreversible losses caused by over- or under-assembly of the propelled parts.

[0028] 2) By providing an overall structure, the present invention allows the transmission component and the guide component to cooperate with each other. The movement of the assembly shaft is driven by the guide component to move the transmission component and the position feedback column. The position of the position feedback column can be seen directly through the axial opening, which can directly judge the assembly state of the assembly and the assembly shaft. This eliminates the assembly error caused by the machining process deviation of the assembly and the assembly shaft, which not only ensures the consistency of the assembly, but also improves the reliability of the product operation.

[0029] 3) The overall structure of this invention does not have a displacement sensor and is a purely mechanical mechanism, which avoids assembly errors caused by misoperation of electrical components. The mechanical structure determines the initial and final states of the assembly and eliminates assembly errors caused by deviations in the processing technology of the parts.

[0030] 4) By setting the first and second inclined planes, the present invention can change the direction of force transmission, making it easier for operators to observe. Attached Figure Description

[0048] As described in the background section, existing technologies suffer from the problem that displacement sensors cannot accurately locate the assembly position. To address this technical problem, this invention proposes a hydraulic thruster propulsion position monitoring mechanism.

[0049] Example 1

[0050] In a typical embodiment of the present invention, reference is made to Figure 1 and Figure 2 As shown, a hydraulic thruster propulsion position monitoring mechanism includes a transmission member 15 installed radially on the assembly. One end of the transmission member 15 extends into the axial process hole of the assembly. One end of the transmission member 15 at the axial process hole contacts a guide member 16. An elastic member is provided at the other end of the transmission member 15. The end of the elastic member away from the transmission member 15 is limited. The transmission member 15 is connected to a position feedback column 12. The position feedback column 12 is installed at the axial opening of the assembly. When the assembly shaft moves relative to the assembly, it contacts the guide member and thus drives the position feedback column to move radially.

[0051] A first inclined surface is provided at the end of the conductive member 15 that contacts the guide member 16, and a second inclined surface is provided at the end of the guide member that contacts the conductive member. The first and second inclined surfaces cooperate with each other. When the assembly shaft 25 does not push the guide member 16, the first and second inclined surfaces of the guide member 16 are in close contact with each other. The first and second inclined surfaces can be parallel to each other, or the sum of their inclination angles is 90°. (Reference) Figure 3 and Figure 4 As shown, when the assembly shaft 25 pushes the guide member 16, the guide member pushes the transmission rod 15 upward.

[0052] In this embodiment, the central axes of the conductive member and the guide member are perpendicular to each other. The conductive member 15 is a conductive rod with a set length. The cross-section of the conductive rod can be circular. The length of the conductive rod is less than the width of the assembly (ring) (the radial width of the assembly where the conductive rod is located). Considering the movement of the conductive member, the outer diameter or width of the section of the conductive member 15 near the guide member 16 is less than the outer diameter or width of the middle section and the other section. The diameter of the larger diameter section of the conductive member is adapted to the inner diameter of the radial opening of the assembly.

[0053] Among them, reference Figure 6 and Figure 7 As shown, the guide member 16 includes a first segment 162 and a second segment 163, which are connected. The end of the first segment 162 near the assembly shaft is a hemispherical surface, and the side of the second segment 163 away from the first segment has a second inclined surface. The first segment has a predetermined length, and the width or diameter of the first segment is smaller than the maximum width or maximum diameter of the second segment. (Refer to...) Figure 5 , Figure 6 and Figure 7 As shown, the guide member has a protrusion 161 on the bottom side of the first section.

[0054] In addition, to prevent the guide 16 from rotating when it moves in the assembly 24, the guide 16 and the assembly 24 are in a sliding fit.

[0055] Specifically, in this embodiment, a protrusion 161 is provided on the bottom side of the guide member. The protrusion 161 is a cuboid. The protrusion is provided along the side of the first segment and the second segment. The protrusion covers a part of each of the first segment and the second segment. The protrusion forms a guide key. The mounting set 24 is provided with a sliding groove. The protrusion is inserted into the sliding groove. Under the action of the mounting shaft 25, the protrusion of the guide member is pushed to move linearly along the sliding groove. The sliding groove of the mounting set 24 is provided on the side close to the mounting shaft.

[0056] The position feedback column 12 is T-shaped and is perpendicularly connected to the conductor 15. The central axis of the position feedback column 12 is parallel to the central axis of the assembly 24. The cross-section of the position feedback column 12 can be square or circular. Thus, the width or diameter of the position feedback column 12 is smaller than the width or diameter of the axial opening. The width or diameter of the axial opening can ensure the vertical movement of the position feedback column. Thus, the position feedback column moves along the radial direction of the assembly at the axial opening. In this embodiment, the cross-section of the position feedback column is circular.

[0057] Specifically, the position feedback post 12 can be a screw, and the side of the transmission element 15 has a threaded hole. The screw is fastened to the threaded hole of the transmission element 15. The position feedback post is a countersunk screw. Therefore, the axial opening of the assembly 24 is also T-shaped to avoid interference with the movement of the position feedback post.

[0058] The conductive element 15 is installed at the radial opening of the assembly 24. From the outside to the inside, the adjusting bolt 13, the elastic element and the conductive element are arranged in sequence in the radial opening. The adjusting bolt limits the conductive element and the elastic element. The adjusting bolt can be tightened at the radial opening of the assembly 24 (the radial opening is provided with internal thread at the location of the adjusting bolt). The radial opening of the assembly is countersunk to facilitate the installation of the adjusting bolt. Moreover, the adjusting bolt 13 can easily adjust the position of the conductive element 15 at the radial opening.

[0059] Understandably, the elastic element is spring 14, one end of spring 14 is fitted onto the screw of adjusting bolt 13, the outer diameter of spring 14 is smaller than the diameter of the conductive element, and the inner diameter of spring is matched with the screw diameter of adjusting bolt.

[0060] In addition, a process hole plug 11 is provided at the axial process hole, and a guide is provided at the axial process hole. There is a set distance between the guide and the end face of the axial process hole. In order to prevent the guide from detaching from the axial process hole, a process hole plug 11 is provided on the side of the axial process hole away from the guide. The process hole plug 11 is a plug.

[0061] The position feedback column 12 of the mechanism is used to provide feedback on the relative displacement between the assembly 24 and the assembly shaft 25. The adjusting bolt 13 is used to adjust the moving load of the transmission component 15. The spring 14 is used to ensure that the transmission component 15 and the guide component 16 are always in close contact. The guide component 16 is in contact with the assembly shaft 25 and moves synchronously with the axial displacement of the assembly shaft 25.

[0062] During the assembly of assembly piece 24 and assembly shaft 25, a pusher tool consisting of pusher 21, pull rod 22, and clamping sleeve 23 is used due to assembly process requirements. High-pressure hydraulic oil is injected through oil hole 241, and operating pusher 21 causes axial displacement of pull rod 22, thereby pushing assembly piece 24 to the right, and consequently causing relative displacement between assembly piece 24 and assembly shaft 25. (Reference) Figure 3 and Figure 4 As shown, when the assembly shaft moves to the left and contacts the guide 16, the inclined surface of the guide 16 pushes the transmission 15 to move radially, which in turn drives the position feedback column 12 to move radially. The operator judges the actual assembly state of the assembly 24 and the assembly shaft 25 based on the displacement of the position feedback column 12.

[0063] Example 2

[0064] This embodiment provides a hydraulic thruster, including a thruster 21 connected to a pull rod 22. The pull rod 22 is circumferentially provided with a clamping sleeve 23, which is connected to a mounting assembly 24. An assembly shaft 25 is provided at the opening in the middle of the mounting assembly 24. One end of the pull rod 22 is connected to the assembly shaft 25. A hydraulic thruster propulsion position monitoring mechanism as described in Embodiment 1 is provided at the mounting assembly. The mounting assembly is provided with an oil hole 241. To ensure the dynamic balance of the mounting assembly 24 during rotation, the mounting assembly is also provided with a dynamic balance counterweight hole 242. The oil hole 241 and the dynamic balance counterweight hole 242 are located on the same side of the mounting assembly. The dynamic balance counterweight hole 242 and the radial opening are located on the same plane, and their central axes are on the same straight line. The length of the dynamic balance counterweight hole is shorter than the length of the radial opening. A counterweight is installed at the dynamic balance counterweight hole 242.

[0065] Understandably, the pusher 21, the pull rod 22, the clamping sleeve 23, and the assembly shaft 25 are all existing technologies.

[0066] Example 3

[0067] This embodiment provides a method for judging the assembly status of a large-bore engine, using a hydraulic thruster propulsion position monitoring mechanism as described in Embodiment 1, including the following:

[0068] The assembly is equipped with an axial process hole, and a guide is provided at the axial process hole. One end of the guide is located outside the axial process hole, and the guide can be slidably installed at the assembly via a protrusion.

[0069] The assembly is equipped with a radial opening, and a conductive element is installed at the radial opening. One end of the conductive element extends into the axial process hole and contacts the guide element.

[0070] The equipment is equipped with an axial opening, and a position feedback column is installed at the axial opening. The position feedback column is connected to the transmission component.

[0071] Install the assembly shaft at the assembly assembly point, and hydraulic oil enters the oil hole of the assembly assembly. Operate the pusher to make the pull rod axially displaced, which pushes the assembly assembly to move, so that the assembly assembly and the assembly shaft have relative displacement.

[0072] When the assembly shaft moves and contacts the guide component, the guide component pushes the transmission component to move radially, which in turn drives the position feedback column to move radially. The operator judges the assembly status of the assembly and the assembly shaft based on the displacement of the position feedback column.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
