Description

Technical Field

[0001] The present invention relates to the field of rudder shaft assembly processing, in particular to a rudder shaft assembly processing tool. Background Art

[0002] The rudder shaft and shift fork are key components in an aircraft's mechanical control system. They play a vital role in flight control, ensuring that the pilot's inputs are accurately transmitted to the control surfaces, thereby adjusting the flight attitude. Therefore, the precision of the fit between the rudder shaft and shift fork is crucial to the accuracy of pilot input transmission. The rudder shaft and shift fork are typically secured together using pins, which are inserted through holes drilled in the rudder shaft and shift fork to secure them. Currently, drilling holes for the rudder shaft and shift fork is typically done separately. However, due to subtle differences between drill bits, holes drilled with different drill bits may have lower fit precision than holes drilled with the same drill bit. Furthermore, drilling the rudder shaft and shift fork separately is very likely to cause the equipment securing the rudder shaft or shift fork to repeatedly adjust its position during placement and removal, which can further increase the error in the hole position of the rudder shaft or shift fork.

[0028] The rudder shaft and the shift fork are key components in the aircraft's mechanical control system. They play an important role in flight control, ensuring that the pilot's operations can be accurately transmitted to the rudder surface, thereby adjusting the flight attitude. Therefore, the matching accuracy of the rudder shaft and the shift fork is the key to affecting the accuracy of the pilot's operation transmission. The matching of the rudder shaft and the shift fork is usually achieved through a pin shaft, which is fixed by drilling holes on the rudder shaft and the shift fork and inserting the pin shaft into the hole. At present, the method of drilling holes for the rudder shaft and the shift fork is usually to separate the rudder shaft and the shift fork for drilling. However, since each drill bit may have slight differences, the matching accuracy of the holes drilled by different drill bits is lower than that of the holes drilled by the same drill bit. In addition, drilling holes for the rudder shaft and the shift fork separately is very likely to cause the equipment fixing the rudder shaft or the shift fork to repeatedly adjust its attitude during the process of taking and placing the rudder shaft or the shift fork, which is very likely to further increase the error of the rudder shaft or the shift fork hole position. In order to address this problem, the present embodiment provides a rudder shaft assembly 03 processing tooling, such as Figure 1 、 Figure 2 As shown, this may include:

[0029] Processing component 01;

[0030] Positioning assembly 02, the positioning assembly 02 includes a first pressing module 21 and a second pressing module 23; the first pressing module 21 abuts against the processing assembly 01 along a first reference direction; wherein the first reference direction is perpendicular to the abutment surface between the first pressing module 21 and the processing assembly 01; one end of the second pressing module 23 abuts against the processing assembly 01 along the first reference direction; the first pressing module 21 and the second pressing module 23 are spaced apart;

[0031] The rudder shaft assembly 03 includes a rudder shaft module 31 and a fork module 32; the outer surface of the rudder shaft module 31 abuts the inner surface of the 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 fork module 32 is clamped with the first clamping module 21;

[0032] The rudder shaft assembly 03 processing tooling includes a first working state and a second working state, and the first working state includes: the processing assembly 01 drives the first clamping module 21 and the second clamping module 23 to squeeze the rudder shaft module 31 to a first position along the first reference direction; 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 processing assembly 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 out of contact with the first clamping module 21 and / or the second clamping module 23.

[0033] In this embodiment, if Figure 1 、 Figure 2 As shown, this embodiment provides a rudder shaft assembly 03 processing tool, which may include:

[0034] Processing assembly 01; positioning assembly 02, positioning assembly 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 (the direction indicated by X in the figure) abuts against the processing assembly 01; one end of the second clamping module 23 abuts against the processing assembly 01 along the first reference direction; the first clamping module 21 and the second clamping module 23 are spaced apart; in this embodiment, the material of the first clamping module 21 and the second clamping module 23 is a metal material known to those skilled in the art and applicable to the scenario in which this embodiment is located, such as a known high-strength steel;

[0035] The rudder shaft assembly 03 includes a rudder shaft module 31 and a fork module 32; the outer surface of the rudder shaft module 31 abuts against the inner surface of the 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 length direction of the first clamping module 21, and the other end abuts against the second clamping module 23; the fork module 32 is clamped with the first clamping module 21; in this embodiment, the rudder shaft module 31 and the fork module 32 are key components of the aircraft mechanical control system. When drilling the rudder shaft module 31 and the fork module 32, the outer peripheral surface of the predetermined position of the rudder shaft module 31 can be abutted against the inner peripheral surface of the predetermined position of the fork module 32. The abutting effect can be understood as the rudder shaft module 31 and the fork module 32 being in a coupled state after abutting and matching, so that the positions of the rudder shaft module 31 and the fork module 32 are not easily misaligned when subjected to a small external force. However, when the external force is large, especially the force along the axis direction of the rudder shaft module 31, the rudder shaft module 31 or the fork module 32 will be misaligned. When the block 32 produces a push-pull effect, the rudder shaft module 31 and the fork module 32 may be misaligned. In this embodiment, since the direction in which the processing component 01 drills the rudder shaft module 31 and the fork module 32 is along the radial direction of the predetermined area of the fork module 32 and the rudder shaft module 31, the rudder shaft module 31 and / or the fork module 32 are subjected to a small thrust or pull 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 fork module 32. One end of the rudder shaft module 31 along its length direction is abutted with the end of the first clamping module 21 away from the processing component 01, and the other end is abutted with the end of the second clamping module 23 away from the processing component 01, and the fork module 32 is clamped with the first clamping module 21, thereby realizing the overall positioning of the rudder shaft assembly 03. By drilling the rudder shaft module 31 and the fork module 32 together by the processing component 01, the problem of large errors caused by drilling the rudder shaft and the fork separately can be solved.

[0036] In some embodiments, as Figure 1 、 Figure 2As shown, the positioning assembly 02 also includes a blocking module 22; the blocking module 22 is annular; one end face of the blocking 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 fork module 32; the inner circumferential surface of the blocking module 22 abuts against the outer circumferential surface of the rudder shaft module 31; the end of the second clamping module 23 close to the rudder shaft module 31 abuts against the end of the fork module 32 away from the blocking module 22.

In this embodiment, the baffle module 22 can prevent the end face of the fork module 32 from contacting the rudder shaft module 31. It can be imagined that in the process of drilling the rudder shaft module 31 and the fork module 32, the rudder shaft module 31 and the fork module 32 will generate mechanical vibration. By setting the baffle module 22, it can be avoided that when the rudder shaft module 31 and the fork module 32 generate mechanical vibration, the end face of the fork module 32 The surface contacts the rudder shaft module 31, which may generate greater friction, and one end face of the blocking 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 fork module 32; the inner circumference of the blocking module 22 abuts against the outer circumference of the rudder shaft module 31; the end of the second clamping module 23 close to the rudder shaft module 31 abuts against the end of the fork module 32 away from the blocking module 22; under the action of the blocking module 22, the first clamping module 21 and the second clamping module 23, the positioning of the fork module 32 and the rudder shaft module 31 can be achieved.

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

The first connecting portion 312 and the first processed portion 313 are in a cylindrical shape. In this embodiment, the outer peripheral surface of the first processed portion 313 abuts against the inner peripheral surface of the fork module 32. The first processed portion 313 is a drilling site. The fork module 32 and the first processed portion 313 are drilled along the radial direction of the first processed portion 313 by a drill bit, so that the first processed portion 313 and the fork module 32 are drilled with the same drill bit, and the errors in hole position and hole diameter are small.

[0041] In this embodiment, if Figure 1 、 Figure 2 、 Figure 6When the second machining portion 321 and the first machining portion 313 are drilled, the drill bit can make the diameters of the holes drilled in the first machining portion 313 and the second machining portion 321 substantially equal, with a small error. Moreover, by abutting one end face of the second machining portion 321 along its axial direction against the baffle module 22 and the other end face against the second pressing module 23, the position of the second machining portion 321 can be fixed, thereby avoiding misalignment of the second machining portion 321 and the first machining portion 313, thereby affecting the drilling accuracy. In this embodiment, 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, as shown in FIG. Figure 1 、 Figure 2 As shown, since the first fork portion 322 and the second fork portion 323 are fixedly connected to part of the outer circumferential surface of the second processing portion 321, when the inner surface of the second processing portion 321 abuts the outer surface of the first processing portion 313, it can be imagined that under the action of gravity, the first fork portion 322 and the second fork portion 323 will apply a torsional force along its circumferential direction to the second processing portion 321, causing the second processing portion 321 to produce a slight rotation relative to the first processing portion 313. In this case, in order to offset the torsional force applied by the first fork portion 322 and the second fork portion 323 to the second processing portion 321, the third clamping slot 325 is clamped with the first clamping module 21 to offset the torsional force, thereby making the drilling accuracy on the first processing portion 313 and the second processing portion 321 higher.

When the first fork portion 322 and the second fork portion 323 apply a torsional force along the circumferential direction of the second processing portion 321 to the second processing portion 321 under the action of gravity, the presence of the positioning portion 213 can prevent the first fork portion 322 and the second fork portion 323 from rotating, so that the first processing portion 313 and the second processing portion 321 will not rotate relative to each other along the circumferential direction of the first processing portion 313, thereby ensuring the processing accuracy of the drilling.

[0054] The working principle of the present invention is:

[0055] When it is necessary to drill holes in the rudder shaft module 31 and the fork module 32, the processing component 01 drives the first clamping module 21 and the second clamping module 23 to squeeze the rudder shaft module 31 close to each other along the first reference direction 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 fork module 32 and the rudder shaft module 31 from the outer peripheral surface of the fork module 32 along the radial direction of the fork module 32 until the predetermined holes are obtained; when the holes on the fork module 32 and the rudder shaft module 31 are processed, 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 component 03 is taken out.
