Description

Technical Field

[0001] This invention relates to the field of spline processing technology, and more specifically, to a spline component processing apparatus and method. Background Technology

[0002] The transmission of torque via gear meshing between external and internal splines is a fundamental mechanical structure. The precision of the splines affects the smoothness of power transmission and the fit between components. Typically, when an internal spline mates with an external spline, a blind hole exists within the internal spline. As the external spline gradually penetrates the blind hole to engage with the internal spline, it compresses the air within the blind hole, increasing resistance and affecting the assembly efficiency of the external and internal splines. Usually, a milling cutter is used to remove one of the spline teeth from the external spline, creating a channel connecting the blind hole to the outside air to balance the internal and external air pressure. Therefore, it is crucial to ensure stable clamping of the external spline to prevent its axis from tilting when not fully clamped, which could cause the milling cutter to interfere with or mill other spline teeth, thus affecting the strength of the external spline.

[0003] In existing machining equipment, a V-clamping device is typically used to fix both ends of the external spline. However, a significant amount of time is required to adjust the position of the V-clamping device during clamping, after which the tool mills the spline teeth above the external spline. This V-clamping device wastes considerable adjustment time and has poor clamping effectiveness. The axis of the external spline is prone to misalignment, causing the milling position to change and potentially milling onto other spline teeth. This affects the torque transmission effect after the spline teeth mate with the internal spline, further weakening torque transmission. Therefore, how to improve the clamping effect of the spline assembly while achieving rapid movement of part of the machining equipment during the fixing process has become a pressing technical problem in this field. Summary of the Invention

[0004] To address the issue of improving the clamping effect of spline components while enabling rapid movement of some processing devices during the fixing process, this invention provides a spline component processing device and method.

[0005] In a first aspect, the present invention provides a spline component processing apparatus, comprising:

[0006] The base assembly includes a reference plane;

[0007] The fixing component includes a first fixing unit and an engagement unit; the first fixing unit is fixedly disposed on the base component.

[0008] A sliding assembly includes a first sliding unit and a second sliding unit disposed opposite to the fixed assembly and slidably mounted on the base assembly; the second sliding unit is located between the first sliding unit and the first fixed unit; the engaging unit is disposed on the side of the first fixed unit facing the second sliding unit; wherein, the first sliding unit includes a first sliding portion slidably connected to the base assembly and a second sliding portion slidably connected to the first sliding portion; the second sliding portion and the second sliding unit have an inclined surface that can abut against each other along a first direction; the inclined surface has a first angle range with the reference surface; the reference surface is a plane on the base assembly that provides the sliding assembly for sliding;

[0009] In the processing state of the spline assembly processing device, the second sliding part is driven to provide a force that pushes the second sliding unit to slide closer to the first fixed unit. At the same time, based on the movement of the second sliding part along the second direction, the point of application of the force on the second sliding unit gradually moves away from the reference surface. The clamping force applied by the second sliding unit to the spline assembly gradually increases as the point of application moves away from the reference surface. The spline assembly engages with the meshing unit and is clamped by the second sliding unit.

[0010] Optionally, the second sliding unit includes an integrally formed first main body, a second main body, and a third main body; the first main body is slidably connected to the base assembly along a first direction on the reference surface; the second main body is connected to the first main body along a second direction; the third main body is connected to the second main body along a second direction; wherein, the side of the second main body and the third main body facing the fixing assembly is a beveled surface, the beveled surface of the second main body and the beveled surface of the third main body are connected to form a pressing area that can abut against the spline assembly; there is a preset angle between the beveled surface of the second main body and the beveled surface of the third main body; in the initial state of the spline assembly processing device, the angle between the beveled surface of the second main body and the reference surface is smaller than the angle between the beveled surface of the third main body and the reference surface.

[0011] Optionally, the second sliding unit further includes a second connecting portion; the second connecting portion includes a rotating rod and a sliding block; the sliding block is slidably connected to the base assembly; the rotating rod is disposed on the sliding block and rotatably connected to the first main body.

[0012] Optionally, the side of the second sliding portion facing the second sliding unit is the inclined surface; the side of the second sliding unit facing the second sliding portion is the inclined surface; the first angle range between the inclined surface and the reference surface is not greater than 90°; in the processing state, based on the fact that the clamping force gradually increases as the point of application moves away from the reference surface, the first clamping force applied by the third main body to the spline assembly is greater than the second clamping force applied by the third main body to the spline assembly in the initial state.

[0013] Optionally, the width of the second sliding part in the first direction gradually decreases along the second direction; the width of the first main body in the first direction gradually increases along the second direction; in the processing state, based on the movement of the second sliding part along the second direction, the second sliding part provides a force on the second sliding unit, and the angle between the chamfer of the second main body and the reference plane is equal to the angle between the chamfer of the third main body and the reference plane.

[0014] Optionally, the sliding assembly further includes a first connecting portion that extends through the first sliding portion along a second direction; the first connecting portion includes a limiting portion and a sliding rod; one end of the sliding rod is connected to the limiting portion, and the other end extends through the second sliding portion and is slidably connected to the second sliding portion; the limiting portion abuts against the end face of the fixing assembly away from the second sliding portion; in the processing state, the limiting portion is driven to rotate, and the sliding rod drives the second sliding portion to move in a direction close to or away from the base assembly.

[0015] Optionally, the first sliding portion is provided with a second sliding groove extending in a second direction; at least a portion of the second sliding portion is located in the second sliding groove and is slidably connected to the first sliding portion.

[0016] Optionally, the fixing component further includes a second fixing unit; the second fixing unit is disposed on the first fixing unit; at least a portion of the second fixing unit has its orthographic projection along the axial direction of the spline component coincides with the orthographic projection along the axial direction of the spline component; in the processing state, the side of the second fixing unit facing the spline component abuts against the end face of the spline component.

[0017] Optionally, the tool assembly includes a tool base, a mounting unit, and a tool unit; the mounting unit is disposed on the tool base; the tool unit is disposed on the mounting unit; in the machining state, the tool unit machines a spline tooth of the spline assembly along the axial direction of the spline assembly.

[0018] Secondly, the present invention provides a method for processing a spline component, comprising:

[0019] Since the spline assembly is located between the engagement unit and the second sliding unit, the driving second sliding part provides a force that pushes the second sliding unit to slide closer to the first fixed unit;

[0020] Since the spline assembly is located between the engagement unit and the second sliding unit, the driving second sliding part provides a force that pushes the second sliding unit to slide closer to the first fixed unit;

[0021] As the second sliding part moves along the second direction, the point of application of the force applied to the second sliding unit gradually moves away from the reference surface, and the clamping force applied by the second sliding unit to the spline assembly gradually increases as the point of application moves away from the reference surface.

[0022] The spline assembly engages with the engagement unit and is clamped by the second sliding unit.

[0023] To address the issue of simultaneously improving the clamping effect of the spline assembly while enabling rapid movement of some processing devices during the fixing process, this invention offers the following advantages:

[0024] By using a fixed component and a sliding component in conjunction, the spline assembly can be quickly fixed and clamped. The fixed component is located on one side of the spline assembly, and the sliding component is located opposite the fixed component on the other side of the spline assembly. It works with the sliding component to fix the spline assembly and prevent it from falling. At the same time, it provides a certain space to place the spline assembly and makes it suitable for spline assemblies of different sizes. In order to realize the rapid movement of some processing devices, the second sliding part and the second sliding unit are set as mutually abutting inclined surfaces. The second sliding part provides a force to push the second sliding unit to slide quickly towards the first fixed unit. As the point of application of the force provided by the second sliding part on the second sliding unit moves in the direction of movement of the second sliding part (i.e., moves away from the reference surface), the clamping force applied by the second sliding unit to the spline assembly gradually increases, and the spline assembly is gradually clamped. The engagement of the spline assembly with the meshing unit further limits the circumferential rotation of the spline assembly. Compared with the V-shaped clamping device that fixes the two ends of the external spline in related technologies, the clamping effect of the spline assembly is improved. Attached Figure Description

[0037] In related spline machining devices, V-shaped devices are usually used to fix the two ends of the external spline for machining. However, this device requires constant adjustment of the position of the V-shaped device during the clamping process, and the clamping effect on the external spline assembly is not good. It is easy for the axis of the external spline assembly to shift during the machining process, resulting in a change in the milling position, which affects the torque transmission effect after the external spline and internal spline are mated. Therefore, there is a need for a spline machining device that can improve the clamping effect on the spline assembly while enabling rapid movement of some machining devices during the fixing process.

[0038] Example 1:

[0039] This embodiment discloses a spline component processing device. Please refer to [reference needed]. Figure 2 The spline assembly processing device includes:

[0040] The base assembly 10 includes a reference surface; specifically, the base assembly 10 includes a base body 11 and a first sliding groove 12. The base body 11 provides a reference surface for placing the first fixed unit 21, the first sliding unit 31 and the second sliding unit 32 to prevent the bottom surface from being unstable and affecting the machining accuracy. The first sliding groove 12 is used to regulate the movement trajectory of the first sliding unit 31 and the second sliding unit 32.

[0041] The fixing component 20 includes a first fixing unit 21 and a meshing unit 22. The first fixing unit 21 is fixedly disposed on the base component 10. Specifically, the first fixing unit 21 includes a first fixing part 211 and a second fixing part 212. The first fixing part 211 is disposed on the base component 10, and the second fixing part 212 is perpendicularly connected to the first fixing part 211 along the second direction Y. The meshing unit 22 is disposed on the second fixing part 212. The meshing unit 22 consists of multiple rows of gears arranged in parallel along the axial direction. The tooth profile of each row of gears meshes with the spline teeth 512 of the corresponding spline component 50, so that the meshing unit 22 and the spline component 50 mesh with each other.

[0042] Further, please refer to Figure 1 In related technologies, a V-shaped device is used to clamp the two ends of the spline assembly 50 for fixing. This device requires a lot of time to adjust the position (to align the spline teeth 512 to be milled with the tool) during the clamping process. In the device of the present invention, for fixing the spline assembly 50, after placing the spline assembly 50 on the first fixing unit 21 and the sliding assembly 30, only the second sliding unit 32 needs to be moved to fix the spline assembly 50 on the device, thereby improving the overall processing efficiency.

[0043] The sliding assembly 30 includes a first sliding unit 31 and a second sliding unit 32, which are disposed opposite to the fixed assembly 20 and slidably disposed on the base assembly 10. The second sliding unit 32 is located between the first sliding unit 31 and the first fixed unit 21. The engaging unit 22 is disposed on the side of the first fixed unit 21 facing the second sliding unit 32. The first sliding unit 31 includes a first sliding portion 311 slidably connected to the base assembly 10 and a second sliding portion 312 slidably connected to the first sliding portion 311. The second sliding portion 312 and the second sliding unit 32 have an inclined surface that can abut against each other along a first direction X. The inclined surface has a first angle range with a reference surface. The reference surface is a plane that provides sliding space for the sliding assembly 30 on the base assembly 10.

[0044] For details, please refer to Figure 5 and Figure 6The first sliding portion 311 includes a first block 3111, a second block 3112, and a mounting hole 3114. The first block 3111 contacts the base assembly 10, and the second block 3112 is connected to the first block 3111 along a second direction. At least a portion of the second block 3112 extends along a first direction above the second sliding portion 312. The mounting hole 3114 is located on the second block 3112 above the second sliding portion 312 and is used to place the first connecting portion 313 mentioned below. Further, the second sliding portion 312 is a trapezoidal structure that is narrower at the top and wider at the bottom. This structure can effectively output the force that pushes the second sliding unit 32 during movement. The second sliding unit 32 is a V-shaped block with a first angle range preferably of 45°-60°, but also 30°-45° or 60°-70°. The first direction refers to the horizontal plane facing the fixing assembly 20.

[0045] Specifically, the first direction refers to the direction on the horizontal plane toward the fixed component 20, and the second direction refers to the vertical direction perpendicular to the reference plane; the first direction and the second direction are set perpendicular to each other.

[0046] In the processing state of the spline assembly processing device, the driving second sliding part 312 provides a force to push the second sliding unit 32 to slide closer to the first fixed unit 21. Simultaneously, based on the movement of the second sliding part 312 along the second direction, the point of application of the force on the second sliding unit 32 gradually moves away from the reference surface. The clamping force applied by the second sliding unit 32 to the spline assembly 50 gradually increases as the point of application moves away from the reference surface. The spline assembly 50 engages with the engagement unit 22 and is clamped by the second sliding unit 32. Specifically, the second sliding part 312 includes a third block 3121 and a sliding hole 3122. The third block 3121 refers to the aforementioned inclined structure. The sliding hole 3122 penetrates the interior of the third block 3121 along the second direction. The sliding hole 3122 cooperates with the first connecting part 313, facilitating the subsequent application of a force by the first connecting part 313 to move the second sliding part 312 along the second direction.

[0047] This is understandable, please refer to it. Figure 1In the relevant technology, the push block 01 in the V-shaped device is set as a trapezoidal structure that is wider at the top and narrower at the bottom. The point of application of the force applied by the push block 01 on the V-block 02 gradually moves closer to the bottom of the moving block 03 as the push block 01 moves. As the point of application moves, the V-block 02 abuts against the push block 01 and moves away from the external spline, resulting in an unsatisfactory clamping effect on the external spline. The fixed block 04 is set opposite to the V-block 02 with the external spline in between. The fixed block 04 and the V-block 02 need to cooperate to fix the external spline. The moving block 03 is connected next to the push block 01. When the external spline is fixed on the machining component, the cutter 05 directly above the external spline will mill the external spline teeth. When the push block 01 provides force to push the V-block 02 to clamp the external spline, part of the force is used to overcome the friction caused by the vertical pressure, which greatly reduces the effective output pushing force and makes it impossible to achieve rapid movement of some machining devices.

[0048] Specifically, the second sliding part 312 and the second sliding unit 32 form a wedge-shaped mating pair through mutually abutting inclined surfaces. During the downward movement of the second sliding part 312 along the second direction, the normal thrust it exerts on the second sliding unit 32 can be decomposed into two components: a horizontal component and a vertical component. Since the inclined surface forms an acute angle with the reference plane, the vertical component is transformed into an effective thrust that propels the second sliding unit 32 to slide horizontally along the first direction through the guiding effect of the inclined surface.

[0049] Furthermore, as the second sliding part 312 continues to move downward along the second direction, the contact point (i.e., the point of application of the force) between its inclined surface and the inclined surface of the second sliding unit 32 gradually moves from the lower region to the upper region of the inclined surface, that is, gradually moves away from the reference surface. This upward movement of the point of application means that the second sliding part 312 gradually deepens its wedging into the second sliding unit 32, and the proportion of the horizontal component of the normal thrust increases, causing the horizontal clamping force applied by the second sliding unit 32 to the spline assembly 50 to show a non-linear growth trend. This progressive force-increasing characteristic ensures that the second sliding unit 32 can quickly approach the spline assembly 50 in the initial stage to achieve rapid movement, and also provides a sufficiently large clamping force in the final stage to achieve effective clamping, thus balancing processing efficiency and clamping stability.

[0050] Furthermore, as the second sliding part 312 pushes the second sliding unit 32, the second sliding unit 32 gradually approaches the spline assembly 50, and the clamping force applied by the second sliding unit 32 to the spline assembly 50 gradually increases with the movement of the second sliding part 312 until the spline assembly 50 is clamped.

[0051] Further, the second sliding unit 32 includes an integrally formed first main body portion 321, a second main body portion 322, and a third main body portion 323; the first main body portion 321 is slidably connected to the base assembly 10 along a first direction on a reference plane; the second main body portion 322 is connected to the first main body portion 321 along a second direction; the third main body portion 323 is connected to the second main body portion 322 along a second direction; wherein, the side of the second main body portion 322 and the third main body portion 323 facing the fixing assembly 20 is a beveled surface. The beveled surfaces of the second main body 322 and the third main body 323 are connected to form a pressing area that can abut against the spline assembly 50. The pressing area has a V-shaped structure and is used to accommodate and press the outer periphery of the spline assembly 50. There is a preset angle between the beveled surfaces of the second main body 322 and the third main body 323. In the initial state of the spline assembly processing device, the angle between the beveled surface of the second main body 322 and the reference surface is smaller than the angle between the beveled surface of the third main body 323 and the reference surface.

[0052] For details, please refer to Figure 2 , Figure 3 and Figure 4 For ease of understanding, in this invention, the angle between the oblique surface of the second main body 322 and the reference plane is set to α1, and the angle between the oblique surface of the third main body 323 and the reference plane is set to α2. The oblique surface of the second main body 322 facing the fixing component 20 is inclined upward, while the oblique surface of the third main body 323 facing the fixing component 20 is inclined downward. The preset angle formed between the two is preferably 60°, but can be 80° or 90°. In the initial state, the second sliding part 312 abuts against the second sliding unit 32, providing a pushing force. The second sliding unit 32 moves closer to the spline assembly 50. Since the point of application of the force of the second sliding unit 32 is far from the spline assembly 50 at this time, the force cannot be applied or transmitted to the third main body 323 to clamp the spline assembly 50. The third main body 323 and the spline assembly 50 have a small gap. Therefore, the third main body 323 does not completely abut against the spline assembly 50. Compared with the second main body 322, the third main body 323 is farther from the reference plane. Therefore, the angle α2 between the oblique surface of the third main body 323 and the reference plane is larger.

[0053] Furthermore, the second sliding unit 32 also includes a second connecting part 324; the second connecting part 324 includes a rotating rod 3241 and a sliding block 3242; the sliding block 3242 is slidably connected to the base assembly 10; the rotating rod 3241 is disposed on the sliding block 3242 and is rotatably connected to the first main body 321.

[0054] This is understandable, please refer to it. Figure 2 and Figure 7The sliding block 3242 is slidably connected to the base assembly 10 and can reciprocate along the first direction; the rotating rod 3241 is disposed on the sliding block 3242 and rotatably connected to the first main body 321. Specifically, the rotation axis of the rotating rod 3241 extends along the axial direction of the spline assembly 50. In the processing state, the rotating rod 3241 is locked and maintains the position of the first main body 321; when the spline assembly 50 needs to be removed after processing, it is only necessary to release the abutment force of the second sliding part 312, and the second sliding unit 32 as a whole can swing around the axis of the rotating rod 3241 to the side away from the fixed assembly 20 by a preset angle (e.g., 5° to 15°), so that the second main body 322 and the third main body 323 quickly disengage from the spline assembly 50. Compared to related technologies that require the entire V-block to be completely moved back to the starting position before workpieces can be picked up or placed, this invention achieves rapid retraction of the second sliding unit 32 at a small angle by swinging the rotating rod 3241, shortening the travel of the second sliding unit 32 and thus further improving processing efficiency.

[0055] Furthermore, the side of the second sliding part 312 facing the second sliding unit 32 is an inclined surface; the side of the second sliding unit 32 facing the second sliding part 312 is an inclined surface; the first angle range between the inclined surface and the reference surface is no greater than 90°; in the processing state, based on the fact that the clamping force gradually increases as the point of application moves away from the reference surface, the first clamping force applied by the third main body part 323 to the spline assembly 50 is greater than the second clamping force applied by the third main body part 323 to the spline assembly 50 in the initial state.

[0056] Specifically, the first angle range is again limited to not exceeding 90° within the range described above. The first angle range is preferably 45°-60°. The point of application of the force provided by the second sliding part 312 on the second sliding unit 32 moves with the direction of movement of the second sliding part 312 (i.e., moves away from the reference plane). The force applied by the third main body part 323 in the second sliding unit 32 to the spline assembly 50 gradually approaches the spline assembly 50, so the clamping force applied by the third main body part 323 to the spline assembly 50 also increases. When the extension line of the force passes through the central axis of the spline assembly 50 and is parallel to the reference plane, this is the optimal clamping position, that is, the included angles of α1 and α2 are equal. Combined with the engagement unit 22 on the first fixing unit 21, the spline assembly 50 is restricted from circumferential rotation during processing, thereby improving the clamping effect on the spline assembly 50.

[0057] Furthermore, the width of the second sliding portion 312 in the first direction gradually decreases along the second direction; the width of the first main body portion 321 in the first direction gradually increases along the second direction; in the processing state, based on the movement of the second sliding portion 312 along the second direction, the second sliding portion 312 provides a force on the second sliding unit 32, and the angle between the oblique surface of the second main body portion 322 and the reference surface is equal to the angle between the oblique surface of the third main body portion 323 and the reference surface.

[0058] For details, please refer to Figure 2 and Figure 4 As can be seen from the above, in the initial state, the angle α2 between the third main body 323 and the reference plane is greater than the angle α1 between the second main body 322 and the reference plane. That is, the clamping force applied by the third main body 323 to the spline assembly 50 is less than that of the second main body 322. As the width of the second sliding part 312 gradually decreases in the second direction and the width of the first main body 321 of the second sliding unit 32 gradually increases in the second direction, the force applied by the second sliding part 312 to the second sliding unit 32 makes the third main body 323 closer to the spline assembly 50. Finally, the angle α2 between the third main body 323 and the reference plane is equal to the angle α1 between the second main body 322 and the reference plane. When the two angles are equal, it means that the clamping forces applied by the second main body 322 and the third main body 323 to the spline assembly 50 are almost equal, thereby ensuring the clamping effect on the spline assembly 50.

[0059] Furthermore, the sliding assembly 30 also includes a first connecting portion 313 that extends through the first sliding portion 311 along a second direction; the first connecting portion 313 includes a limiting portion 3131 and a sliding rod 3132; one end of the sliding rod 3132 is connected to the limiting portion 3131, and the other end extends through the second sliding portion 312 and is slidably connected to the second sliding portion 312; the limiting portion 3131 abuts against the end face of the fixing assembly 20 away from the second sliding portion 312; in the processing state, the limiting portion 3131 is driven to rotate, and the sliding rod 3132 drives the second sliding portion 312 to move in a direction close to or away from the base assembly 10. Specifically, since the second sliding part 312 and the second sliding unit 32 are connected by an inclined surface, and the second sliding part 312 needs to provide force to the second sliding unit 32 by moving up and down, the first connecting part 313 that passes through the first sliding part 311 and the second sliding part 312 is needed to drive the second sliding part 312 to move up and down. When driving the second sliding part 312 to move up and down, the limiting part 3131 is fixed on the first sliding part 311, and the second sliding part 312 is moved by the rotation of the sliding rod 3132.

[0060] Furthermore, the first sliding portion 311 is provided with a second sliding groove 3113 extending along the second direction; at least a portion of the second sliding portion 312 is located within the second sliding groove 3113 and is slidably connected to the first sliding portion 311. Specifically, the second sliding groove 3113 is provided to limit the trajectory of the second sliding portion 312 moving along the second direction, preventing the second sliding portion 312 from swaying due to the torque of the first connecting portion 313, thereby preventing it from erratically moving and affecting the force output to the second sliding unit 32. The first connecting portion 313 is provided to provide power for the second sliding portion 312 to move along the second sliding groove 3113.

[0061] Furthermore, the fixing assembly 20 also includes a second fixing unit 23; the second fixing unit 23 is disposed on the first fixing unit 21; at least a portion of the orthographic projection of the second fixing unit 23 along the axial direction of the spline assembly 50 coincides with the orthographic projection of the spline assembly 50 along the axial direction; in the machining state, the side of the second fixing unit 23 facing the spline assembly 50 abuts against the end face of the spline assembly 50. Specifically, the second fixing unit 23 includes a third fixing part 231 and a fourth fixing part 232. The third fixing part 231 is connected to the second fixing unit 23, and the fourth fixing part 232 abuts against the end face of the spline assembly 50 while being connected to the third fixing part 231. The abutment of the fourth fixing part 232 against the end face of the spline assembly 50 further fixes the spline assembly 50, preventing the spline assembly 50 from axially moving under the force during machining by the tool unit 42, thereby affecting the machining accuracy.

[0062] Furthermore, the spline assembly processing apparatus also includes:

[0063] The tool assembly 40 includes a tool base (not shown), a mounting unit 41, and a tool unit 42. The mounting unit 41 is disposed on the tool base; the tool unit 42 is disposed on the mounting unit 41. In the machining state, the tool unit 42 machines a spline tooth 512 of the spline assembly 50 along the axial direction of the spline assembly 50. Specifically, the tool unit 42 is disposed above the spline assembly 50, and the spline tooth 512 to be machined on the spline assembly 50 is aligned with the tool unit 42 by clamping the spline assembly 50 by the machining device.

[0064] Furthermore, the spline assembly 50 includes a spline shaft 51 and a shaft body 52. ​​The spline shaft 51 is placed on the fixing component 20 and the second sliding unit 32. The shaft body 52 is connected to the spline shaft 51 and suspended in the air. The spline shaft 51 includes a shaft 511 and spline teeth 512. The spline teeth 512 are wrapped around the shaft 511. The part that needs to be machined in the spline assembly 50 is the spline teeth 512. Therefore, the second sliding unit 32 and the fixing component 20 need to clamp the spline shaft 51 in the spline assembly 50.

[0065] Example 2:

[0066] This embodiment discloses a method for processing a spline component, the method comprising steps S10-S30:

[0067] In step S10, based on the fact that the spline assembly 50 is located between the engagement unit 22 and the second sliding unit 32, the second sliding part 312 is driven to provide a force that pushes the second sliding unit 32 to slide closer to the first fixed unit 21; specifically, the movement of the second sliding unit 32 depends on the force provided by the movement of the second sliding part 312 along the second direction.

[0068] In step S20, based on the movement of the second sliding part 312 along the second direction, the point of application of the force on the second sliding unit 32 gradually moves away from the reference surface, and the clamping force of the second sliding unit 32 on the spline assembly 50 gradually increases as the point of application moves away from the reference surface; furthermore, as the point of application of the force of the second sliding part 312 on the spline assembly 50 moves away from the reference surface, the point of application of the force of the second sliding unit 32 gets closer and closer to the spline assembly 50, and the force is applied to or transmitted to the third main body 323 so that the spline assembly 50 is clamped.

[0069] In step S30, the spline assembly 50 engages with the engagement unit 22 and is clamped by the second sliding unit 32. Specifically, the second sliding unit 32 applies a certain clamping force to one side of the spline assembly 50, while the other side of the spline assembly 50 engages with the engagement unit, limiting its circumferential rotation and further improving the fixing effect of the spline assembly 50.

[0070] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made in form and detail without departing from the scope of the present invention.
