Description

Technical Field

[0001] This invention relates to the field of rudder shaft assembly processing, and more specifically, to a rudder shaft assembly processing fixture. Background Technology

[0002] Control shafts and shift forks are key components of an aircraft's mechanical control system, playing a crucial role in flight control by ensuring the precise transmission of pilot inputs to the control surfaces, thereby adjusting flight attitude. Therefore, the precision of the fit between the control shaft and shift fork is critical to the accuracy of pilot input transmission. The control shaft and shift fork are typically fitted together using pins, which are inserted into holes drilled in the control shaft and shift fork to secure them. Currently, the common method for drilling control shafts and shift forks is to drill them separately. However, due to slight differences in drill bits, holes drilled with different bits may have lower fit precision compared to holes drilled with the same drill bit. Furthermore, drilling the control shaft and shift fork separately can potentially increase the error in the hole position due to repeated attitude adjustments made by the equipment used to fix the control shaft or shift fork during loading and unloading.

[0028] The rudder shaft and shift fork are key components of an aircraft's mechanical control system, playing a crucial role in flight control and ensuring that pilot inputs are accurately transmitted to the control surfaces to adjust flight attitude. Therefore, the precision of the fit between the rudder shaft and shift fork is critical to the accuracy of pilot input transmission. The rudder shaft and shift fork are typically fitted together using pins, which are inserted into holes drilled in the rudder shaft and shift fork to secure them. Currently, the drilling method for the rudder shaft and shift fork usually involves drilling the rudder shaft and shift fork separately. However, due to slight differences in drill bits, holes drilled with different bits may have lower fit precision compared to holes drilled with the same drill bit. Furthermore, drilling the rudder shaft and shift fork separately can potentially increase the error in the hole position due to repeated attitude adjustments made by the equipment used to fix the rudder shaft or shift fork during loading and unloading. To address this issue, this embodiment provides a rudder shaft assembly 03 machining fixture, such as... Figure 1 , Figure 2 As shown, it may include:

[0029] Processing component 01;

[0030] The positioning component 02 includes a first clamping module 21 and a second clamping module 23; the first clamping module 21 abuts against the processing component 01 along a first reference direction; wherein the first reference direction is perpendicular to the abutment surface of the first clamping module 21 and the processing component 01; one end of the second clamping module 23 abuts against the processing component 01 along the first reference direction; the first clamping module 21 and the second clamping module 23 are spaced apart.

[0031] The rudder shaft assembly 03 includes a rudder shaft module 31 and a shift fork module 32; the outer surface of the rudder shaft module 31 abuts against the inner surface of the shift fork module 32; one end of the rudder shaft module 31 abuts against the end of the first clamping module 21 away from the processing assembly 01 along the first reference direction, and the other end abuts against the second clamping module 23 along the first reference direction; the shift fork module 32 is engaged with the first clamping module 21.

[0032] The machining fixture for the rudder shaft assembly 03 includes a first working state and a second working state. The first working state includes: the machining component 01 driving the first clamping module 21 and the second clamping module 23 to move closer to each other along the first reference direction and press the rudder shaft module 31 to a first position; wherein the first position is the position where the first clamping module 21 and the second clamping module 23 fix the rudder shaft module 31. The second working state includes: the machining component 01 driving the first clamping module 21 and the second clamping module 23 to move away from each other along the first reference direction to a second position; wherein the second position is the position where the rudder shaft module 31 is no longer in contact with the first clamping module 21 and / or the second clamping module 23.

[0033] In this embodiment, as Figure 1 , Figure 2 As shown, this embodiment provides a machining fixture for a steering shaft assembly 03, which may include:

[0034] Processing component 01; positioning component 02, the positioning component 02 includes a first clamping module 21 and a second clamping module 23; one end face of the first clamping module 21 along a first reference direction (X indicates the direction in the figure) abuts against the processing component 01; one end of the second clamping module 23 along the first reference direction abuts against the processing component 01; the first clamping module 21 and the second clamping module 23 are spaced apart; in this embodiment, the materials of the first clamping module 21 and the second clamping module 23 are metal materials known to those skilled in the art that can be applied to the scenario in which this embodiment is located, such as known high-strength steel;

[0035] The rudder shaft assembly 03 includes a rudder shaft module 31 and a shift fork module 32. The outer surface of the rudder shaft module 31 abuts against the inner surface of the shift fork module 32. One end of the rudder shaft module 31 abuts against the end of the first clamping module 21 away from the processing component 01 along the length direction of the first clamping module 21, and the other end abuts against the second clamping module 23. The shift fork module 32 is engaged with the first clamping module 21. In this embodiment, the rudder shaft module 31 and the shift fork module 32 are key components of the aircraft's mechanical control system. When drilling holes in the rudder shaft module 31 and the shift fork module 32, the outer peripheral surface of the rudder shaft module 31 at a predetermined position can abut against the inner peripheral surface of the shift fork module 32 at a predetermined position. This abutment effect can be understood as the rudder shaft module 31 and the shift fork module 32 becoming coupled after abutment and engagement, making it less likely for the positions of the rudder shaft module 31 and the shift fork module 32 to misalign under small external forces. However, when the external force is large, especially the force along the axial direction of the rudder shaft module 31, it will cause the rudder shaft module 31 or the shift fork module to misalign. When block 32 produces a push-pull effect, misalignment may occur between the rudder shaft module 31 and the shift fork module 32. In this embodiment, since the drilling direction of the machining component 01 for the rudder shaft module 31 and the shift fork module 32 is along the radial direction of the predetermined area of ​​the shift fork module 32 and the rudder shaft module 31, the rudder shaft module 31 and / or the shift fork module 32 are subjected to relatively small pushing or pulling forces in the axial direction. In this embodiment, the rudder shaft assembly 03 is formed by abutting the outer surface of the rudder shaft module 31 with the inner surface of the shift fork module 32. One end of the rudder shaft module 31 along its length direction abuts the end of the first clamping module 21 away from the machining component 01, and the other end abuts the end of the second clamping module 23 away from the machining component 01. The shift fork module 32 is also engaged with the first clamping module 21, thereby achieving overall positioning of the rudder shaft assembly 03. By drilling the rudder shaft module 31 and the shift fork module 32 together by the machining component 01, the problem of large errors caused by drilling the rudder shaft and shift fork separately can be solved.

[0036] In some embodiments, such as Figure 1 , Figure 2As shown, the positioning component 02 further includes a partition module 22; the partition module 22 is annular; one end face of the partition module 22 along its axial direction abuts against the rudder shaft module 31, and the other end face abuts against one end face of the shift fork module 32; the inner circumferential surface of the partition module 22 abuts against the outer circumferential surface of the rudder shaft module 31; the end of the second pressing module 23 near the rudder shaft module 31 abuts against the end of the shift fork module 32 away from the partition module 22.

[0037] In this embodiment, as Figure 1 , Figure 2 As shown, the positioning component 02 also includes a baffle module 22; the baffle module 22 is annular; in this embodiment, the baffle module 22 can be made of plastic or metal with a certain hardness. In this embodiment, the baffle module 22 can prevent the end face of the shift fork module 32 from contacting the rudder shaft module 31. It can be imagined that during the drilling process of the rudder shaft module 31 and the shift fork module 32, the rudder shaft module 31 and the shift fork module 32 will generate mechanical vibration. By setting the baffle module 22, it is possible to avoid the end face of the shift fork module 32 from contacting the rudder shaft module 31 and the shift fork module 32 when mechanical vibration occurs. The surface of the partition module 22 comes into contact with the rudder shaft module 31, which may cause significant friction. One end face of the partition module 22 along its axial direction abuts against the rudder shaft module 31, and the other end face abuts against one end face of the shift fork module 32. The inner circumferential surface of the partition module 22 abuts against the outer circumferential surface of the rudder shaft module 31. The end of the second clamping module 23 near the rudder shaft module 31 abuts against the end of the shift fork module 32 away from the partition module 22. Under the action of the partition module 22, the first clamping module 21, and the second clamping module 23, the positioning of the shift fork module 32 and the rudder shaft module 31 can be achieved.

[0038] In some embodiments, such as Figure 5 As shown, the steering shaft module 31 includes a cylindrical first connecting portion 312, a first processing portion 313, and a second connecting portion 314; wherein the diameter of the first connecting portion 312 is larger than the diameter of the first processing portion 313; the diameter of the first processing portion 313 is larger than the diameter of the second connecting portion 314; one end of the first connecting portion 312 along its axial direction is fixedly connected to one end of the first processing portion 313 along its axial direction, and the other end abuts against the first pressing module 21; the other end of the first processing portion 313 along its axial direction is fixedly connected to one end of the second connecting portion 314 along its axial direction; the other end of the second connecting portion 314 along its axial direction abuts against the second pressing module 23; the end of the first connecting portion 312 away from the first pressing module 21 abuts against one end of the partition module 22 along its axial direction; the outer peripheral surface of the first processing portion 313 abuts against the inner peripheral surface of the partition module 22; the outer peripheral surface of the first processing portion 313 abuts against the inner peripheral surface of the shift fork module 32.

[0039] In this embodiment, as Figure 5 As shown, the rudder shaft module 31 includes a cylindrical first connecting part 312, a first machining part 313, and a second connecting part 314. In this embodiment, the outer peripheral surface of the first machining part 313 abuts against the inner peripheral surface of the shift fork module 32. The first machining part 313 is a drilling part. The shift fork module 32 and the first machining part 313 are drilled by a drill bit along the radial direction of the first machining part 313, so that the error of the hole position and hole diameter of the first machining part 313 and the shift fork module 32 is small under the action of the same drill bit.

[0040] In some embodiments, such as Figure 1 , Figure 2 , Figure 6 As shown, the shift fork module 32 includes a second processing section 321, a first shift fork section 322, a second shift fork section 323, a connecting hole 324, and a third slot 325; the first shift fork section 322 and the second shift fork section 323 are respectively fixedly connected to the second processing section 321; the first shift fork section 322 and the second shift fork section 323 are spaced apart; the connecting hole 324 penetrates through both end faces of the second processing section 321 along the axial direction of the second processing section 321; the third slot 325 extends from the first processing section 321 along the thickness direction of the first shift fork section 322. The fork portion 322 extends from one end face away from the second fork portion 323 and penetrates the end face of the second fork portion 323 away from the first fork portion 322; the inner surface of the second processing portion 321 abuts against the outer surface of the first processing portion 313; one end face of the second processing portion 321 along its axial direction abuts against the partition module 22, and the other end face abuts against the second pressing module 23; the first fork portion 322 or the first fork portion 322 and the second fork portion 323 are engaged with the first pressing module 21 through the third slot 325.

[0041] In this embodiment, as Figure 1 , Figure 2 , Figure 6As shown, the inner surface of the second processing part 321 abuts against the outer surface of the first processing part 313; when the drill bit drills into the second processing part 321 and the first processing part 313, under the action of the same drill bit, the drilling diameters of the first processing part 313 and the second processing part 321 can be made to be basically equal, with a small error; and by abutting one end face of the second processing part 321 along its axial direction with the partition module 22 and the other end face with the second clamping module 23, the position of the second processing part 321 can be fixed, avoiding misalignment between the second processing part 321 and the first processing part 313, thereby affecting the drilling accuracy; in this embodiment, the first shift fork part 322 or the first shift fork part 322 and the second shift fork part 323 are engaged with the first clamping module 21 through the third slot 325, as shown. Figure 1 , Figure 2 As shown, since the first shift fork portion 322 and the second shift fork portion 323 are fixedly connected to part of the outer peripheral surface of the second processing portion 321, when the inner surface of the second processing portion 321 abuts against the outer surface of the first processing portion 313, it can be imagined that under the action of gravity, the first shift fork portion 322 and the second shift fork portion 323 will apply a torque along its circumferential direction to the second processing portion 321, causing the second processing portion 321 to rotate slightly relative to the first processing portion 313. In this case, in order to counteract the torque applied to the second processing portion 321 by the first shift fork portion 322 and the second shift fork portion 323, the torque can be counteracted by engaging with the first clamping module 21 through the third slot 325, thereby making the drilling accuracy on the first processing portion 313 and the second processing portion 321 higher.

[0042] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the first clamping module 21 includes a first clamping part 211 and a positioning part 213; one end face of the first clamping part 211 along the first reference direction abuts against the processing component 01, and the other end face is fixedly connected to one end face of the positioning part 213; the end face of the first clamping part 211 fixedly connected to the positioning part 213 abuts against one end face of the first connecting part 312 along its axial direction; the first shift fork part 322 or the first shift fork part 322 and the second shift fork part 323 are engaged with the positioning part 213 through the third slot 325.

[0043] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the first clamping module 21 includes a first clamping part 211 and a positioning part 213; in this embodiment, the shape of the first clamping part 211 can be a cube or a rectangle; the first clamping part 211 is along the first reference direction ( Figure 1 , Figure 2One end face of the first clamping part 211 (in the direction indicated by X) abuts against the processing component 01, and the other end face is fixedly connected to one end face of the positioning part 213. In this embodiment, the processing component 01 can apply a pushing or pulling force to the first clamping part 211, thereby causing the first clamping part 211 to apply a force to the first connecting part 312. In this embodiment, the end face of the first clamping part 211 away from the processing component 01 along the first reference direction abuts against the end face of the first connecting part 312 along its axial direction, and the first shift fork part 322 or the first shift fork part 322 and the second shift fork part 323 are connected to the positioning part 213 via the third slot 325. 3. Snap-fit; In this embodiment, the protruding part of the outer surface of the positioning part 213 can be rounded to facilitate the positioning part 213 to pass into the third slot 325. When the first shift fork part 322 and the second shift fork part 323 apply a torque along the circumferential direction of the second processing part 321 under the action of gravity, the presence of the positioning part 213 can prevent the first shift fork part 322 and the second shift fork part 323 from rotating, so that the first processing part 313 and the second processing part 321 will not rotate relative to each other along the circumferential direction of the first processing part 313, thus ensuring the processing accuracy of the drilling.

[0044] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the first clamping module 21 further includes a limiting groove 212; the limiting groove 212 is recessed inward from the end face where the first clamping part 211 is connected to the positioning part 213 along the first reference direction; the limiting groove 212 extends from one end face of the first clamping part 211 to the other end face along the second reference direction; wherein the second reference direction is the height direction of the first clamping part 211, and the rudder shaft module 31 further includes a locking part 311; the locking part 311 is fixedly connected to the end face of the first connecting part 312 away from the first processing part 313; the locking part 311 is engaged with the limiting groove 212.

[0045] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the first pressing module 21 also includes a limiting groove 212; the limiting groove 212 is recessed inward from the end face where the first pressing part 211 connects to the positioning part 213 along the first reference direction; the limiting groove 212 is recessed along the height direction of the first pressing part 211 ( Figure 2The Y-direction (which is perpendicular to the X-direction) extends from one end face of the first pressing part 211 to the other end face; in this embodiment, the limiting groove 212 is rectangular in shape, with one end penetrating one end face of the first pressing part 211 along its height direction, and the other end spaced apart from the other end face of the first pressing part 211 along its height direction; the rudder shaft module 31 also includes a locking part 311; the locking part 311 and the end face of the first connecting part 312 away from the first processing part 313. Fixed connection; the engaging part 311 engages with the limiting groove 212; in some cases, when the engaging part 311 engages with the limiting groove 212, the engaging part 311 can abut against the closed end face of the limiting groove 212 along the height direction of the first pressing part 211, and at this time the third slot 325 on the first shift fork part 322 or the first shift fork part 322 and the second shift fork part 323 engages with the positioning part 213, thereby enabling better positioning of the first pressing module 21 and the second pressing module 23. It is conceivable that when drilling holes in the first processing part 313 and the second processing part 321, the processing component 01 will apply pressure to the first processing part 313 and the second processing part 321. In this embodiment, after the processing component 01 applies pressure to the first processing part 313 and the second processing part 321, the closed end of the limiting groove 212 along the height direction of the first pressing part 211 can apply a force in the opposite direction to the locking part 311. The first shift fork part 322 or the first shift fork part 322 and the second shift fork part 323 can also apply a force in the opposite direction to the positioning part 213, thereby keeping the positions of the rudder shaft module 31 and the shift fork module 32 relatively fixed, further improving the drilling accuracy during the processing.

[0046] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 As shown, the second clamping module 23 includes a second clamping part 231, a first slot 232, and a second slot 233; the first slot 232 is recessed inward from one end face of the second clamping part 231 along the axial direction of the second clamping part 231; the second slot 233 is recessed from one end face of the second clamping part 231 along the axial direction of the second clamping part 231 and communicates with the first slot 232; the diameter of the first slot 232 is larger than the diameter of the second slot 233; the end of the second clamping part 231 away from the first connecting part 312 abuts against the processing component 01 along the first reference direction.

[0047] In this embodiment, as Figure 1 , Figure 2 , Figure 4As shown, the second clamping module 23 includes a second clamping part 231, a first slot 232, and a second slot 233; the first slot 232 is recessed inward from one end face of the second clamping part 231 along the axial direction of the second clamping part 231; the second slot 233 is recessed inward from one end face of the second clamping part 231 along the axial direction of the second clamping part 231 and communicates with the first slot 232, and the diameter of the first slot 232 is larger than the diameter of the second slot 233, thereby forming a stepped surface inside the second clamping part 231; when the second connecting part 31 When the second clamping part 231 is inserted into the first slot 232, it can abut against the second processing part 321, thereby positioning the second processing part 321. In this embodiment, the end face of the second connecting part 314 inserted into the first slot 232 along its axial direction abuts against the aforementioned stepped surface. At this time, the second processing part 321 can abut against the partition module 22, thereby fixing the second processing part 321 and preventing misalignment between the second processing part 321 and the first processing part 313 during processing, which would result in substandard processing quality.

[0048] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 As shown, the second clamping module 23 also includes an observation port 234; the observation port 234 extends from the outer peripheral surface of the second clamping part 231 along the radial direction of the second clamping part 231 into the second slot 233.

[0049] In this embodiment, as Figure 1 , Figure 2 , Figure 4 As shown, the second clamping module 23 also includes an observation port 234; by extending the observation port 234 from the outer peripheral surface of the second clamping part 231 along the radial direction of the second clamping part 231 into the second slot 233, a notch is opened on the outer peripheral surface of the second clamping part 231 for observing the relative positional changes of the first processing part 313 and the second processing part 321 during the drilling process, thereby further determining the positional changes of the first processing part 313 and the second processing part 321. For example, it can be determined whether the first processing part 313 and the second processing part 321 are misaligned due to vibration during the drilling process.

[0050] In some embodiments, such as Figure 1 , Figure 2As shown, the processing component 01 includes a first clamping module 11, a second clamping module 12, a support module, and a drive module; the first clamping module 11 and the second clamping module 12 are slidably connected to the support module; the drive module is detachably connected to the support module; one end of the first clamping module 11 is drivenly connected to the drive module, and the other end abuts against the end of the first clamping part 211 away from the rudder shaft assembly 03; one end of the second clamping module 12 is drivenly connected to the drive module, and the other end abuts against the end of the second clamping part 231 away from the rudder shaft assembly 03.

[0051] In this embodiment, as Figure 1 , Figure 2 As shown, the processing component 01 includes a first clamping module 11, a second clamping module 12, a support module (not shown in the figure), a drive module (not shown in the figure), and a processing module (not shown in the figure). The support module can be understood as a support frame for the processing component 01. The first clamping module 11 and the second clamping module 12 are mounted on the support module, and the first clamping module 11 and the second clamping module 12 are slidably connected to the support module, respectively. The fixed ends of the drive module and the processing module are detachably connected to the support module, respectively. One end of the first clamping module 11 is connected to the output end of the drive module, and the other end abuts against the end of the first clamping part 211 away from the rudder shaft assembly 03. One end of the second clamping module 12 is connected to the other output end of the drive module, and the other end abuts against the end of the second clamping part 231 away from the rudder shaft assembly 03. This enables the drive module to drive the first clamping module 11 and / or the second clamping module 12 to apply pressure to the first clamping module 21 and / or the second clamping module 23. In this embodiment, the processing module is used to drill holes in the first processing part 313 and the second processing part 321. It can be imagined that the processing module includes a drill bit for drilling, a motor, and other components that drive the drill bit to move up and down. The processing assembly 01 also includes a control module (not shown in the figure), which is used to control the operation of the drive module and the processing module.

[0052] In some embodiments, such as Figure 1 , Figure 2 As shown, the processing component 01 further includes a displacement detection module 13; the fixing part of the displacement detection module 13 is connected to the support module; the detection part of the displacement detection module 13 abuts against the first shift fork part 322 or the second shift fork part 323.

[0053] In this embodiment, as Figure 1 , Figure 2As shown, the processing component 01 also includes a displacement detection module 13; the fixed part of the displacement detection module 13 is connected to the support module, and the detection part of the displacement detection module 13 abuts against the first shift fork part 322 or the second shift fork part 323. In this embodiment, the displacement detection module 13 can be a dial indicator. The fixed part of the dial indicator is connected to the support module, and the detection part (probe) of the dial indicator abuts against the first shift fork part 322 or the second shift fork part 323. During the drilling process of the second processing part 321 and the first processing part 313, mechanical vibration is unavoidable. By detecting the mechanical vibration of the first processing part 313 and the second processing part 321 during the processing process with a dial indicator, it is possible to observe more intuitively whether the processing vibration is too large and there is a large error.

[0054] The working principle of this invention is as follows:

[0055] When drilling is required on the rudder shaft module 31 and the shift fork module 32, the processing component 01 drives the first clamping module 21 and the second clamping module 23 to move closer to each other along the first reference direction and press the rudder shaft module 31 to a first position; wherein the first position is the position where the first clamping module 21 and the second clamping module 23 fix the rudder shaft module 31; then the processing component 01 drills holes in the shift fork module 32 and the rudder shaft module 31 from the outer peripheral surface of the shift fork module 32 along the radial direction of the shift fork module 32 until a predetermined hole is obtained; after the drilling on the shift fork module 32 and the rudder shaft module 31 is completed, the processing component 01 drives the first clamping module 21 and the second clamping module 23 to move away from each other along the first reference direction to a second position; wherein the second position is the position where the rudder shaft module 31 is separated from the first clamping module 21 and the second clamping module 23, and the rudder shaft assembly 03 is removed.
