Description

Technical Field

[0001] The invention relates to the technical field of rudder stock processing, and in particular to a rudder stock high-precision milling device and a milling method. Background Art

[0002] In the processing of rudder stocks, the processing of the threaded part is crucial to ensure its mechanical strength and precision. In particular, after the thread processing is completed, the milling and grinding of the thread at the end of the rudder stock are important process steps that determine its fatigue resistance and long-term durability. In traditional processing methods, due to the stress concentration problem at the root of the end thread, the rudder stock often suffers from fatigue fracture or increased wear during actual use. Therefore, how to accurately and effectively perform milling and grinding of the thread root has become a key technical issue in the manufacturing of rudder stocks.

[0003] At present, many traditional milling equipments are not precise enough in controlling the root shape when processing the thread end, which easily causes stress concentration and weakens the connection strength between the thread and the rod body. In addition, uneven processing of the thread root may also cause the surface roughness to be substandard, thus affecting the overall assembly accuracy. To address this problem, the milling and grinding processing technology not only needs to consider the effective stress distribution of the thread root, but also needs to use high-precision milling and grinding processes to ensure that the processed thread part has excellent surface quality and fatigue resistance; such as the announcement: CN117259874A Disclosed are a portable thread root milling machine and a root milling method for a ship rudder stock. The device achieves the effect of using the root milling device to mill the threaded section of the rudder stock by supporting the root milling device with a workpiece limiting device. Although a simple root milling effect can be achieved, the following technical problems exist in actual use: 1. The structure of the workpiece limiting device is too simple, and the root milling machine cannot be effectively and quickly adjusted to the correct root milling posture during the root milling process. In addition, due to its low degree of automation and lack of linkage effect during the adjustment process, it is extremely cumbersome to dismantle it, posing a great safety hazard. 2. It can only perform short-range root milling operations, and manual adjustment is required for long-range root milling operations. Moreover, the rear milling area cannot be accurately connected with the front milling area, and the milling accuracy is low. 3. When facing multi-area root milling, especially equidistant multi-area root milling, root milling operations cannot be performed. The degree of automation is low, the accuracy is poor, and there are great limitations. Summary of the invention

[0004] In view of the above problems, a high-precision milling device and a milling method for a rudder stock are provided. By proposing a high-precision milling device that can not only automatically locate the milling root area but also flexibly adjust the milling root area, the technical problems of the existing root milling equipment when milling the rudder stock, such as limited milling root area, low milling accuracy and inability to perform multi-point fixed-distance milling, are solved.

[0005] In order to solve the problems of the prior art, the present invention provides a high-precision milling equipment for a rudder bar, comprising a supporting module and a synchronous clamping module arranged on the supporting module; the synchronous clamping module is provided with a first clamping portion and a second clamping portion which can approach each other and a locking element which can lock the adjusted first clamping portion and the second clamping portion; a rotation driving module is centrally fixed in the middle of the synchronous clamping module and is arranged on a side close to the rudder bar; the milling module is fixedly arranged at the driving end of the rotation driving module through a transverse driving module, the milling module is arranged in a vertical state and the milling end of the milling module is arranged radially toward the rudder bar; two groups of holding modules are arranged, the two groups of holding modules are adjustably arranged on both sides of the milling module, the holding modules are used to ensure that the milling module always maintains a stable posture in the milling state and can adjust the support height according to rudder bars of different diameters.

[0006] Preferably, the synchronous clamping module also includes a driving part capable of driving the first clamping part and the second clamping part to move toward each other and a mounting seat for fixing the driving part; the locking element is vertically arranged on one side of the mounting seat and passes through the mounting seat toward the driving part.

[0007] Preferably, the locking element is a locking bolt, and the locking bolt is threadedly connected to the surface of the mounting seat.

[0008] Preferably, the first clamping portion is composed of a driving rack and a first extension frame vertically arranged on the top of the driving rack; a limiting frame is also fixedly arranged below the other end of the first extension frame away from the driving rack.

[0009] Preferably, the synchronous clamping module is further provided with a traction element capable of radially traction on the first clamping portion and the second clamping portion respectively.

[0010] Preferably, the rotation drive module includes a servo motor, which is fixedly arranged on the middle part of one side of the synchronous clamping module close to the rudder bar through the second extension frame, and the output shaft of the servo motor passes through the second extension frame and is transmission-connected to the rotating frame rotatably arranged on the other side of the second extension frame; the lateral drive module is fixedly arranged in a horizontal state on the far end of the rotating frame.

[0011] Preferably, the transverse driving module is provided with a sliding frame capable of axially sliding along the axis of the rudder stock and a driving unit for driving the sliding frame to slide axially.

[0012] Preferably, the transverse driving module further includes a longitudinal driving unit capable of longitudinally driving the milling module; the longitudinal driving unit is vertically fixedly disposed at the front end of the sliding frame; the milling module is vertically fixedly disposed at the driving end of the longitudinal driving unit.

[0014] A rudder stock high-precision milling method, applied to a rudder stock high-precision milling device, comprises the following steps:

[0015] S1: First, by operating the synchronous clamping module, the first clamping part and the second clamping part are controlled to expand toward each other; when the two clamping parts expand to a suitable space, the rudder stock is fixedly clamped outside thereof, thereby ensuring the stability of the rudder stock during the milling process;

[0042] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] See also Figures 1 to 10 As shown: a high-precision milling equipment for a rudder bar, comprising a supporting module 1, and a synchronous clamping module 2 arranged on the supporting module 1; the synchronous clamping module 2 is provided with a first clamping portion 21 and a second clamping portion 22 which can approach each other and a locking element 3 which can lock the adjusted first clamping portion 21 and second clamping portion 22; a rotation driving module 4 is centrally fixed in the middle of the synchronous clamping module 2 and is arranged on a side close to the rudder bar 8; a milling module 6 is fixedly arranged at the driving end of the rotation driving module 4 through a lateral driving module 5, the milling module 6 is arranged in a vertical state and the milling end of the milling module 6 is arranged radially toward the rudder bar 8; two groups of holding modules 7 are provided, and the two groups of holding modules 7 are adjustably arranged on both sides of the milling module 6, and the holding modules 7 are used to ensure that the milling module 6 always maintains a stable posture in the milling state and can adjust the support height according to the rudder bars 8 with different diameters.

[0044] When the rudder bar 8 needs to be milled, the operator first accurately positions the milling equipment to the end to be processed of the rudder bar 8; next, by operating the synchronous clamping module 2, the first clamping part 21 and the second clamping part 22 are driven to expand toward each other until the two form enough space around the rudder bar 8 for clamping; when the first clamping part 21 and the second clamping part 22 are successfully clamped to the outside of the rudder bar 8, due to their design of moving toward each other, the center of the clamping part can be automatically aligned with the axis of the rudder bar 8 to ensure coaxiality; then, by starting the locking element 3, the connection between the clamping part and the rudder bar 8 is stabilized to prevent the clamping from loosening during the milling process; then, the rotation drive module 4 is started, which drives the milling module 6 to rotate synchronously along the circumferential direction of the axis of the rudder bar 8 through the lateral drive module 5, thereby realizing the adjustment of the milling point, and then the milling module 6 is manipulated to move, thereby realizing accurate root milling of the threaded end of the rudder bar 8; The design not only realizes the precise automatic centering and clamping of the rudder bar 8, but also ensures the stability during the processing; and the structure also has a locking function, which ensures the safety and reliability during the milling process and greatly improves the processing efficiency; the support module 1 is composed of a fixed frame 11 fixedly connected to the synchronous clamping module 2 and a telescopic frame 12 with a sleeve arranged outside the fixed frame 11; a locking bolt 13 is also screwed on the outside of the telescopic frame 12; when the rudder bar 8 is clamped by the synchronous clamping module 2, the locking bolt 13 outside the sleeve is in an unlocked state, and the sleeve will drop under its own weight and contact the ground. After the synchronous clamping module 2 completes the clamping of the rudder bar 8, the locking bolt 13 is re-tightened to lock the sleeve; the support module 1 is used to further support the synchronous clamping module 2 after clamping, so as to prevent the synchronous clamping module 2 from being separated from the rudder bar 8 due to external factors.

[0045] See also Fig. 9 As shown: the synchronous clamping module 2 also includes a driving part 23 capable of driving the first clamping part 21 and the second clamping part 22 to move toward each other and a mounting seat 25 for fixing the driving part 23; the locking element 3 is vertically arranged on one side of the mounting seat 25 and passes through the mounting seat 25 toward the driving part 23.

[0046] The mounting seat 25 is a hollow rectangular shell with two ends opened; the driving part 23 is rotatably disposed in the mounting seat 25;

[0047] A driving disc 24 is coaxially fixedly disposed at one end of the driving portion 23, and the driving disc 24 is used to drive the driving portion 23 to rotate by an external force, thereby achieving the purpose of driving the driving portion 23 to rotate, thereby synchronously driving the first clamping portion 21 and the second clamping portion 22 to move toward each other through the driving portion 23; the driving portion 23 is specifically a gear;

[0048] When it is necessary to drive the first clamping part 21 and the second clamping part 22 to move toward each other so as to clamp the rudder bar 8, the staff only needs to operate the driving part 23, and the driving part 23 rotates to synchronously drive the first clamping part 21 and the second clamping part 22 to move, thereby achieving the effect of synchronously driving the first clamping part 21 and the second clamping part 22 to move closer or farther away from each other; thereby achieving the effect of synchronously clamping the rudder bar 8 and automatically aligning the center of the locking element 3 with the axis of the rudder bar 8 after clamping; the driving part 23 can control its movement direction so that the two clamping parts can be adjusted according to the size or needs of the workpiece to ensure the stability and accuracy of clamping; at the same time, the synchronous clamping module 2 also includes a locking element 3, which can lock the driving part 23. After clamping is completed, the fixed state of the clamping part is ensured by locking the driving part 23, thereby avoiding displacement of the clamping part due to vibration or other external interference, thereby ensuring the stability of clamping.

[0049] See also Fig. 9 As shown: the locking element 3 is a locking bolt 31 , and the locking bolt 31 is threadedly connected to the surface of the mounting seat 25 .

[0050] When the first clamping part 21 and the second clamping part 22 are adjusted by the driving part 23 and reach the desired position, it is necessary to ensure their stability in the working state. At this time, the driving part 23 needs to be locked to synchronously lock the positions of the first clamping part 21 and the second clamping part 22; to this end, the staff only needs to tighten the locking bolt 13 to firmly fix the driving part 23, thereby ensuring that the two clamping parts do not loosen or move during operation; the locking element 3 is not limited to the locking bolt 31, and other locking elements can also be used to achieve the purpose of stepless locking of the driving part 23.

[0051] See also Figure 7 and Figure 8 As shown, the first clamping portion 21 is composed of a driving rack 211 and a first extension frame 212 vertically arranged on the top of the driving rack 211; a limiting frame 213 is fixedly arranged below the other end of the first extension frame 212 away from the driving rack 211.

[0052] The driving rack 211 is matched with the cavity gap opened in the mounting seat 25, so as to achieve a radial guiding effect when the driving rack 211 is driven by the driving part 23, and ensure that the driving rack 211 only slides radially under the guidance of the mounting seat 25;

[0053] The limiting frame 213 is arranged in a V-shape, and a film 214 is also attached to the contact surface between the limiting frame 213 and the rudder stock 8; the film 214 attached to the contact surface of the limiting frame 213 can not only realize that when the rudder stock 8 is clamped, the clamping surface is in flexible contact, but also the friction force of the clamping surface can be greatly increased by the arranged film 214, thereby greatly improving the clamping force;

[0054] When it is necessary to drive the first clamping part 21 to slide radially, the staff only needs to rotate the driving disk 24, and the driving disk 24 will synchronously drive the driving part 23 to rotate in the rotating state, so that the driving rack 211 meshed with itself is driven by the driving part 23 to slide radially in the mounting seat 25, and the limiting frame 213 can be used to clamp the rudder bar 8. At the same time, by arranging the limiting frame 213 in a V-shape, an adaptive clamping effect can be achieved when clamping rudder bars 8 of different diameters.

[0055] See also Figure 7 and Figure 8 As shown, the synchronous clamping module 2 is further provided with a traction element 26 which can radially pull the first clamping portion 21 and the second clamping portion 22 respectively.

[0056] The pulling element 26 is specifically a tension spring; one end of the spring is movably connected to the distal end of the first clamping portion 21, and the other end is movably connected to the locking element 3;

[0057] In the working state, when the staff drives the driving part 23 to rotate, so that the first clamping part 21 and the second clamping part 22 move toward each other and thus clamp the rudder bar 8, the tension springs used to pull the first clamping part 21 and the second clamping part 22 respectively will continue to apply tension to the first clamping part 21 and the second clamping part 22. When the staff drives the driving part 23 coaxially, the first clamping part 21 and the second clamping part 22 will synchronously approach each other under the tension of the tension spring, thereby achieving the effect of automatically clamping the rudder bar 8.

[0058] See also Figure 5 and Figure 8 As shown: the rotation drive module 4 includes a servo motor 41, which is fixedly arranged at the middle part of one side of the synchronous clamping module 2 close to the rudder bar 8 through a second extension frame 42, and the output shaft of the servo motor 41 passes through the second extension frame 42 and is transmission-connected to a rotating frame 43 rotatably arranged at the other side of the second extension frame 42; the lateral drive module 5 is fixedly arranged at the far end of the rotating frame 43 in a horizontal state.

[0059] When it is necessary to drive the transverse driving module 5 and the milling module 6 to move, so as to realize the milling root operation at the threaded end of the rudder stock 8, firstly, an external power supply is connected to drive the servo motor 41 to move, and the output shaft of the servo motor 41 rotates, thereby driving the rotating frame 43 connected to itself to rotate. When the rotating frame 43 is in a rotating state, it synchronously drives the transverse driving module 5 and the milling module 6 to rotate, so as to realize the milling point adjustment by the rotating frame 43, and after the adjustment, cooperate with the milling module 6 to realize the effect of milling the threaded end of the rudder stock 8;

[0060] Through the transmission connection design between the servo motor 41 and the rotating frame 43, the rotation drive module 4 can accurately control the rotating frame 43, thereby providing stable and precise rotational power support for the entire milling process; the high efficiency and precision of the servo motor 41 enable the device to ensure consistent processing quality when milling the rudder bar 8.

[0061] See also Fig.10 As shown, the lateral driving module 5 is provided with a sliding frame 51 capable of axial sliding along the axis of the rudder bar 8 and a driving unit 52 for driving the sliding frame 51 to slide axially.

[0062] The sliding frame 51 is horizontally arranged at the far end of the rotating frame 43, and the frame body is passed through a sliding groove on the rotating frame 43; the driving unit 52 is specifically an electric push rod, which is vertically arranged on the side of the rotating frame 43 away from the rudder bar 8, and the output shaft of the electric push rod passes through the rotating frame 43 and is fixedly connected to the sliding frame 51; when it is necessary to drive the sliding frame 51 to slide circumferentially along the axis of the rudder bar 8, it is only necessary to connect an external power supply to drive the electric push rod to move, and the output shaft of the electric push rod extends to drive the sliding frame 51 to move, thereby achieving the effect of driving the milling module 6 fixed on the sliding frame 51 to move horizontally along the axis of the rudder bar 8 and milling the rudder bar 8.

[0063] See also Fig.10 As shown: the lateral driving module 5 also includes a longitudinal driving unit 53 capable of longitudinally driving the milling module 6; the longitudinal driving unit 53 is vertically fixedly arranged at the front end of the sliding frame 51; the milling module 6 is vertically fixedly arranged at the driving end of the longitudinal driving unit 53.

[0064] The longitudinal drive unit 53 is preferably a screw slide, or an electric push rod, so as to achieve the purpose of driving the milling module 6 to move back and forth in a straight line;

[0065] The longitudinal driving unit 53 is used to drive the milling module 6 to be set longitudinally close to the rudder bar 8, so that when the milling module 6 is moved to the desired milling position under the cooperation of the driving unit 52 and the sliding frame 51, it is necessary to drive it radially so that the milling module 6 is set close to the threaded segment of the rudder bar 8 and the threaded segment is milled; an external power supply can be connected to drive the longitudinal driving unit 53 to work, and at this time the output shaft of the longitudinal driving unit 53 extends, thereby pushing the milling module 6 longitudinally toward the rudder bar 8.

[0066] See also Fig.10 As shown: there are two groups of holding modules 7, and the two groups of holding modules 7 are adjustably arranged on both sides of the sliding frame 51; the holding module 7 is composed of an adjustment frame 71 and a roller 72 rotatably arranged at the far end of the adjustment frame 71; the proximal end of the adjustment frame 71 is connected to the extension plate arranged on the side wall of the sliding frame 51 through an adjustment bolt 73.

[0067] When the sliding frame 51 slides along the axis of the rudder bar 8, the two sets of retaining modules 7 contact the surface of the rudder bar 8 through the rollers 72, ensuring that the sliding frame 51 always maintains smooth operation during the sliding process and preventing deviation problems caused by vibration or friction; at the same time, the design of the adjusting bolt 73 allows fine adjustment of the position of the roller 72 to adapt to rudder bars 8 of different diameters or shapes, so that the device has a wider range of applicability and operational flexibility; the design of the retaining module 7 achieves stable support for the sliding frame 51 during operation through an adjustable structure, effectively preventing deviation and instability caused by the sliding process; at the same time, the setting of the roller 72 reduces the friction between the rudder bar 8, improves the sliding efficiency, and protects the surface of the rudder bar 8 from wear; the coordinated design of the adjusting bolt 73 and the adjusting frame 71 enhances the applicability and flexibility of the equipment, can adapt to rudder bars 8 of different sizes, and improves the versatility and practicality of the device.

[0068] A rudder stock high-precision milling method, applied to a rudder stock high-precision milling device, comprises the following steps:

[0069] S1: First, by operating the synchronous clamping module 2, the first clamping portion 21 and the second clamping portion 22 are controlled to expand toward each other; when the two clamping portions expand to a suitable space, the rudder stock 8 is fixedly clamped outside thereof, thereby ensuring the stability of the rudder stock 8 during the milling process;

[0070] S2: Due to the relative movement of the first clamping part 21 and the second clamping part 22, the centers of the two are automatically coaxially aligned with the axis of the rudder bar 8 during clamping; this design ensures that the center of the rudder bar 8 is consistent with the center line of the movement of the milling module 6, thereby ensuring the accuracy of milling;

[0071] S3: Then, the first clamping part 21 and the second clamping part 22 are locked by operating the locking element 3 to prevent the clamping parts from loosening during the milling process, thereby ensuring the stability of the rudder stock 8;

[0072] S4: Finally, an external power source is connected to drive the servo motor 41 to drive the rotating frame 43 to rotate, thereby driving the rotating frame 43 to synchronously rotate circumferentially along the axis of the rudder bar 8. The rotating frame 43 in the rotating state synchronously drives the milling module 6 to move, adjust the milling point and cooperate with the milling module 6 to perform milling action; when the milling module 6 is moved to the milling point under the drive of the transverse driving module 5, the longitudinal driving unit 53 is immediately driven to move, and the milling module 6 is driven by the longitudinal driving unit 53 to be radially close to the rudder bar 8 until the milling action is completed by the milling module 6.

[0073] The present invention can not only perform self-calibration according to rudder stocks of different diameters, but also the root milling area and point positions can be self-adjusted according to requirements, and the root milling efficiency is fast, the precision is high, and the effect is good.

[0074] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.

The rudder stock high-precision milling equipment according to claim 6, characterized in that: Two groups of holding modules (7) are provided, and the two groups of holding modules (7) are adjustably arranged on both sides of the sliding frame (51) in a relatively opposite manner; the holding module (7) comprises an adjustment frame (71) and a roller (72) rotatably arranged at the far end of the adjustment frame (71); the near end of the adjustment frame (71) is connected to an extension plate arranged on the side wall of the sliding frame (51) via an adjustment bolt (73).

9. A method for high-precision milling of a rudder stock, applied to a high-precision milling device for a rudder stock as claimed in any one of claims 1 to 8, comprising the following steps: S1: First, by operating the synchronous clamping module (2), the first clamping portion (21) and the second clamping portion (22) are controlled to expand toward each other; when the two clamping portions expand to a suitable space, a rudder stock (8) is fixedly clamped outside the two clamping portions, thereby ensuring the stability of the rudder stock (8) during the milling process; S2: Due to the relative movement of the first clamping portion (21) and the second clamping portion (22), the centers of the two are automatically coaxially aligned with the axis of a rudder bar (8) during clamping; this design ensures that the center of the rudder bar (8) is consistent with the center line of the movement of the milling module (6), thereby ensuring the accuracy of milling; S3: Then, the first clamping part (21) and the second clamping part (22) are locked by operating the locking element (3) to prevent the clamping parts from loosening during the milling process, thereby ensuring the stability of the rudder stock (8); S4: Finally, an external power source is connected to drive the servo motor (41) to drive the rotating frame (43) to rotate, thereby driving the rotating frame (43) to synchronously rotate along the axis of a rudder bar (8) in the circumferential direction. The rotating frame (43) in the rotating state synchronously drives the milling module (6) to move, and cooperates with the milling module (6) to perform milling action; when the milling module (6) is moved to the milling point under the drive of the transverse driving module (5), the longitudinal driving unit (53) is immediately driven to move, and the milling module (6) is driven by the longitudinal driving unit (53) to be radially close to a rudder bar (8) until the milling action is completed by the milling module (6).
