Description

Technical Field

[0001] This invention relates to the field of machining tooling technology, and more specifically, to a machining method and system. Background Technology

[0002] Bushings are commonly used in universal joints. They are fixed to the universal joint and can rotate relative to the cross shaft. Therefore, it is necessary to machine grooves for mounting fasteners on the bushings or to machine lubrication grooves, mounting grooves, and other structures within their cavities. During the machining process, the bushing is typically fixed in place, and various tool sequences are switched using the machining center turret to machine different positions of the bushing. For example, the grooves may be machined first, followed by the lubrication grooves or mounting grooves.

[0003] Machining different positions on a bushing requires different tools. Related technologies typically employ tool changing or turret angle adjustment to align the tool with the desired machining location. However, this method leads to recurring problems during different steps, such as tool feed, retraction, tool alignment, or toolpath optimization causing tool interference, thus impacting overall machining efficiency. Therefore, improving the machining efficiency of bushings within the same machining process has become a pressing technical problem to be solved in this field. Summary of the Invention

[0034] To address the problem of improving the processing efficiency of workpiece components, this invention has the following advantages:

[0035] As the machining assembly moves towards the workpiece assembly to the first machining position, this includes the first tool abutting against the inner end face of the workpiece assembly, and the second tool having a first radial spacing on the outer peripheral wall. That is, both the first and second tools are on the machining assembly, and their relative positions are fixed. This avoids the need to disassemble the first tool and adjust the machining assembly orientation to install the second tool during machining, reducing the need for tool retraction and tool changing, thus improving overall machining efficiency. After the first tool finishes machining the inner end face of the workpiece assembly, the machining assembly, carrying the second tool, abuts against the outer peripheral wall of the workpiece assembly. The position of the first tool is spaced apart from the workpiece assembly. The relative positions of the first and second tools are not only fixed but also optimize the tool alignment path during the second tool's machining of the outer peripheral wall of the workpiece assembly, avoiding interference between the two tools and shortening the overall machining time.

[0046] Example 1

[0047] In this embodiment, a processing method is provided; please refer to [the relevant documentation]. Figure 1 This includes the following steps S10-S40:

[0048] Step S10: Based on the movement of the processing component 30 towards the workpiece component 40 to the first processing position, drive the workpiece component 40 to rotate along the axis; wherein, the first processing position includes the first tool 331 abutting against the inner end face of the workpiece component 40 and the second tool 332 being radially spaced from the outer peripheral wall of the workpiece component 40 and having a first gap; the processing component 30 includes a processing unit 31 and a first tool 331 and a second tool 332 disposed on the processing unit 31; the first tool 331 and the second tool 332 are spaced apart.

[0049] In step S20, based on the rotation of the workpiece assembly 40, the first tool 331 processes the inner end face of the workpiece assembly 40 according to the first preset rule; the first preset rule processing means that the workpiece assembly 40 is driven by the drive unit 212 to rotate around the axis, and the first tool 331 on the processing assembly 30 abuts against the second processing position on the workpiece assembly 40.

[0050] Step S30: Based on the second preset rule, drive the processing component 30 to move to the third processing position; wherein, the third processing position includes the second tool 332 abutting against the outer peripheral wall of the workpiece component 40 and the first tool 331 being spaced apart from the inner end face of the workpiece component 40; it can be understood that while the second tool 332 is processing, the position of the first tool 331 is spaced apart from the inner end face of the workpiece component 40 and does not interfere with the processing of the second tool 332.

[0051] In step S40, based on the third machining position, the second tool 332 machines the outer peripheral wall of the workpiece assembly 40.

[0052] Specifically, the first spacing in step S10 refers to the distance between the second tool 332 and the outer peripheral wall of the workpiece assembly 40 along the radial distance without interfering with the machining work of the first tool 331. No numerical limit is imposed; the actual distance is the determining factor. It is understood that both tools are mounted on the machining unit 31. When the first tool 331 approaches the first machining position, the second tool 332 simultaneously approaches the workpiece assembly 40 and is radially spaced from the outer peripheral wall of the workpiece assembly 40. During machining, the simultaneous movement of both tools reduces the time required for pre-setting the machining position and avoids wasted time due to repeated tool feeds or retractions caused by tool changes, thereby improving overall machining efficiency. Further, the step S10, based on the machining assembly 30 moving towards the workpiece assembly 40 to the first machining position and driving the workpiece assembly 40 to rotate along the axis, includes steps S11-S12:

[0053] Step S11: Based on the machining start command, drive the first tool 331 to align with the second machining position along the axial direction; wherein, the second machining position includes the center of the inner end face of the workpiece assembly 40 or an alignment area having a second distance from the center along the radial direction.

[0054] In step S12, based on the alignment of the first tool 331 with the second machining position, the machining assembly 30 is driven to move towards the first machining position in a direction close to the workpiece assembly 40, and the workpiece assembly 40 is driven to rotate along the axis.

[0055] Please refer to Figure 2 and Figure 5 Specifically, before the first tool 331 moves to the first machining position, it will be aligned, i.e., moved to the second machining position, to ensure the accuracy of the machining position when it moves to the first machining position to machine the workpiece assembly 40. The second spacing is the distance between the first tool 331 and the inner end face of the workpiece assembly 40 at the second machining position, and the positional spacing between the second tool 332, which is spaced apart from the first tool 331, and the outer peripheral wall of the workpiece assembly 40.

[0056] Further, in step S20, based on the rotation of the workpiece assembly 40, the first tool 331 processes the inner end face of the workpiece assembly 40 according to a first preset rule, including:

[0057] Based on the rotation of the workpiece assembly 40 along the axis, the first tool 331 is driven to move a first radial stroke from the second processing position in the first direction and process the inner end face of the workpiece assembly 40; wherein, the first direction includes the first tool 331 moving radially outward along the inner end face.

[0058] Please refer to Figure 3 and Figure 5 Understandably, based on the workpiece assembly 40 rotating along its own axis, during the machining process, the machining component 30 abuts against the inner end face of the workpiece assembly 40 to complete the machining. In order to reduce the risk of the first tool 331 colliding with the workpiece assembly 40 and causing damage to the workpiece assembly 40 during the process of aligning with the second machining position and then entering the first machining position, the first tool 331 is made to move radially outward along the inner end face during the machining process, while providing space for subsequent waste chip removal.

[0059] Further, in step S30, based on the second preset rule, the processing component 30 is driven to move to the third processing position, steps S31-S33:

[0060] Step S31: Drive the machining component 30 to move a first axial stroke away from the workpiece component 40 along the axial direction, and the machining component 30 is located at a preset spray position; the preset spray position includes the first tool 331 and the inner end face of the workpiece component 40 being spaced apart along the axial direction, and the second tool 332 and the outer peripheral wall of the workpiece component 40 being spaced apart along the radial direction; optionally, the spray position is set between the first tool 331 and the second tool 332 so that its air outlet can face the machining chamber 42 of the workpiece component 40, so that most of the airflow enters the machining chamber 42 to clean up the waste, and avoids a large amount of airflow being lost outside the machining chamber 42.

[0061] In step S32, based on the waste generated when the first tool 331 processes the inner end face of the workpiece assembly 40, the driving jet unit 32 provides a clean airflow that is sprayed upward into the chamber with a first driving force. It is understood that when the processing assembly 30 is working, most of the waste will fall from the inner end wall of the workpiece assembly 40 into the lower chamber. If enough waste accumulates in the lower chamber, there is a risk of interference with the first tool 331. If interference occurs, it may affect the downward path of the tool; or a very small portion of waste may remain on the first tool 331 as unbroken strips, affecting the processing and even the machining accuracy of the inner wall as the workpiece rotates. Therefore, a clean airflow is needed to blow out when the first tool 331 generates waste during processing, so that the generated waste does not accumulate on the first tool 331, or even leaves the processing chamber 42, improving processing efficiency and workpiece quality.

[0062] In step S33, at least a portion of the clean airflow passes sequentially through the upper chamber, the gap between the first tool 331 and the inner end face of the workpiece assembly 40 which are axially spaced, and the lower chamber of the workpiece assembly 40, blowing at least a portion of the waste chips out of the lower chamber of the workpiece assembly 40; wherein, the workpiece assembly 40 includes a bushing unit 41 and a machining chamber 42 located in the bushing unit 41 and having an opening, and the machining chamber 42 is divided into an upper chamber and a lower chamber based on the first tool 331 being aligned with the second machining position.

[0063] Furthermore, the positional space of the upper and lower chambers changes with the movement of the first tool 331. During the machining process of the first tool 331, the space of the upper chamber gradually decreases as the first tool 331 moves radially outward from the second machining position. The clean airflow passes through the upper chamber and blows a small amount of waste chips from the space on both sides of the first tool 331 to the lower chamber until it is blown out of the machining chamber 42. As the inner end faces of the first tool 331 and the workpiece assembly 40 are spaced apart along the axial direction, the passage space for waste chips increases. The waste chips pass through the upper chamber, the gap between the inner end faces of the first tool 331 and the workpiece assembly 40 spaced apart along the axial direction, and the lower chamber of the workpiece assembly 40 in sequence and are thus carried out, thereby ensuring the cleanliness of the machining chamber 42.

[0064] Please refer to Figure 2 , Figure 5 and Figure 7 Specifically, during the process of the second tool 332 reaching the third machining position, the machining assembly 30 needs to move outward along the axial direction of the workpiece assembly 40, i.e., the first retraction process of the machining assembly 30. During the first retraction process of the first tool 331, the cross-sectional area of ​​the upper chamber decreases, which increases the impact force of the cleaning airflow while maintaining the same cleaning airflow rate. This blows a large amount of waste material into the lower chamber until it is blown out of the machining chamber 42, achieving the cleaning purpose. Furthermore, compared to related technologies that require the machining assembly 30 to be removed before cleaning waste material, this invention achieves cleaning during the movement to the third machining position, improving machining efficiency, and also reduces the impact of waste material residue on the workpiece assembly 40 and the tool during machining.

[0065] Furthermore, step S30, which involves moving the processing component 30 to the third processing position based on the second preset rule, also includes step S34:

[0066] Step S34: Based on the fact that at least some of the waste chips are blown out from the lower chamber of the workpiece assembly 40, the processing assembly 30 is driven to move a second axial stroke away from the workpiece assembly 40 and a second radial stroke in a second direction to a third processing position; the second direction is opposite to the first direction in the radial direction of the inner end face; the second radial stroke is greater than the first radial stroke.

[0067] In other embodiments, two positions of the workpiece assembly 40 to be machined are determined: one is in the inner cavity of the machining assembly 30 for lubrication, and the other is on the outer peripheral wall of the machining assembly 30 for mounting. Furthermore, the positions of the first tool 331 and the second tool 332 in the machining assembly 30 are relatively fixed. In addition to the methods described above, driving the machining assembly 30 to move to the third machining position also includes:

[0068] Based on the fact that a small amount of waste debris is blown out from the lower chamber of the workpiece assembly 40, the machining assembly 30 is driven to move away from the workpiece assembly 40 to the spray position, and then driven to move along a third direction to the third machining position. This third direction includes tilting downwards along the outer peripheral wall of the workpiece assembly 40. It can be understood that throughout the process, the machining assembly 30 first retracts its tool, and then tilts downwards to bring the second tool 332 closer to the third machining position. The initial retraction is to break up the filamentous waste debris remaining on the tool during the first tool 331's machining process, facilitating the cleaning airflow to remove it, and primarily to prevent residual waste debris from affecting the movement of the machining assembly 30, thereby improving machining efficiency.

[0069] Furthermore, step S30, which involves moving the machining component 30 towards the workpiece component 40 to the first machining position, further includes:

[0070] Based on the machining command, the machining component 30 is driven to move along the axial direction toward the workpiece component 40 by a third axial stroke.

[0071] Based on the third axial stroke, the machining component 30 moves to the first machining position; wherein the third axial stroke is greater than the sum of the first axial stroke and the second axial stroke.

[0072] Furthermore, the first axial stroke is the first retraction, during which a gap is left in the upper chamber of the machining chamber 42 to facilitate the entry of cleaning airflow and remove the waste residue remaining in the lower chamber due to gravity. The second axial stroke is the second retraction, which prepares for the subsequent machining component 30 to reach the third machining position. The third axial stroke is the infeed, which is based on the machining command. This action occurs before machining, when the machining component 30 enters the cavity of the workpiece component 40, and the first tool 331 abuts against the inner peripheral wall of the workpiece component 40. At this time, the distance between the machining component 30 and the workpiece component 40 is relatively far. In comparison, the distance moved by the two retractions is within the bushing, and the movement amplitude is not large. This improves the overall machining efficiency of the present invention and avoids the problems of redundant processes caused by the need for complete retraction, a long path before tool changing, and repeated alignment in related technologies.

[0073] Further, in step S34, the driving machining assembly 30 is moved axially away from the workpiece assembly 40 by a second axial stroke, and moved radially in the second direction to the third machining position, which also includes:

[0074] The drive injection unit 32 provides a clean airflow that is injected into the upward chamber with a second driving force; wherein the second driving force is less than the first driving force.

[0075] Understandably, when the first tool 331 retracts for the first time, it leaves the first machining position, creating a gap at the upper end of the machining chamber 42. This means the first tool 331 divides the machining chamber 42 into an upper chamber and a lower chamber. During or after machining, a significant amount of debris accumulates in the machining chamber 42. At this point, a first driving force is needed to provide a cleaning airflow that sprays upwards to the upper chamber, causing the accumulated debris to move from the upper chamber to the lower chamber and eventually fall out of the chamber. Since a larger amount of debris needs to be removed, the first driving force is relatively larger. The second driving force, applied during the second retraction of the first tool 331, involves a cleaning airflow. At this time, the amount of debris in the chamber is not as large as when the first driving force is used to spray the cleaning airflow. It only needs to clean the debris remaining in the lower chamber due to gravity or the debris remaining on the first tool 331. Therefore, this driving force does not need to be as large as the first driving force.

[0076] Furthermore, a processing method further includes step S50:

[0077] In step S50, based on the processing stop command, the processing assembly 30 is driven to move away from the workpiece assembly 40 to the fourth processing position; wherein, the fourth processing position includes the first tool 331 and the second processing position of the workpiece assembly 40 being spaced apart along the axial direction, and the second tool 332 and the outer peripheral wall of the workpiece assembly 40 being spaced apart along the radial direction.

[0078] Furthermore, if processing is stopped midway, the processing component 30 will automatically stop processing and move away from the workpiece component 40 to a safe distance, making it convenient to replace the processing component 30 or other parts that encounter problems at any time.

[0079] Example 2

[0080] In this embodiment, a processing system is provided, specifically including:

[0081] The processing assembly 30 includes a processing unit 31 and a tool unit 33; the processing unit 31 is disposed on the base assembly 10; the tool unit 33 includes a first tool 331 and a second tool 332 disposed on the processing unit 31.

[0082] Please refer to Figure 3 and Figure 6 The mounting assembly 20 includes a rotating unit 21 and a clamping unit 22 disposed opposite to the processing assembly 30; the rotating unit 21 is movably connected to the base assembly 10; the clamping unit 22 is connected to the rotating unit 21.

[0083] The workpiece assembly 40 includes a first cutting tool 331 and a second cutting tool 332 spaced apart along the axial and radial directions of the workpiece assembly 40. The machining system includes a machining state. In the machining state, the clamping unit 22 fixes the workpiece assembly 40, and the machining assembly 30 moves toward the workpiece assembly 40 to a first machining position, driving the workpiece assembly 40 to rotate along the axis. The first cutting tool 331 machines the inner end face of the workpiece assembly 40 according to a first preset rule. Based on a second preset rule, the machining assembly 30 is driven to move to a third machining position. Based on the third machining position, the second cutting tool 332 machines the outer peripheral wall of the workpiece assembly 40.

[0084] The rotating unit 21 includes a rotating part 211 and a driving part 212; the connection method and positional relationship of the components; their respective functions or synergistic effects.

[0085] Please refer to Figure 2 , Figure 4 and Figure 5Specifically, the workpiece assembly 40 includes a bushing unit 41 and a machining chamber 42, with the machining chamber 42 inside the bushing unit 41. The workpiece assembly 40 is also connected to the clamping unit 22 of the mounting assembly 20. In addition to being clamped by the clamping unit 22, the workpiece assembly 40 also requires a fixing unit 23 to support it and prevent it from falling out of the clamping unit 22 during machining rotation. The fixing unit 23 is installed inside the rotating unit 21 and abuts against the workpiece assembly 40 along its axial direction. The rotating unit 21 includes a rotating part 211 and a driving part 212. The driving part 212 is connected to the base assembly 10 inside the rotating unit 21 and provides a force to rotate the rotating part 211 carrying the workpiece assembly 40. The machining unit 31 includes a first body 311, a second body 312, a third body 313, and a limiting body 314. The first body 311 is connected to the base assembly 10 at axial intervals along the workpiece assembly 40 to fix the height of the first cutter 331. The third body 313 is disposed in the cavity of the first body 311, with one side connected to the cutter and the other side connected to the first body 311. During the pre-positioning stage, the third body 313 drives the first cutter 331 to move closer to or further away from the workpiece assembly 40 within the cavity of the first body 311. The second body 312 is connected to the first body 311 above the first body 311 to fix the second cutter 332. The limiting body 314 clamps the second cutter 332 and fixes it with screws. Tightening the screws on the second body 314 adjusts the vertical position of the second cutter 332. The limiting body 314 is connected to the second body 312. The relative position of the first cutter 331 and the second cutter 332 is determined according to the relative position of the limiting body 314 and the third body 313.

[0086] It can be determined that when the machining assembly 30 moves, the first tool 331 and the second tool 332 move closer to or further away from the workpiece assembly 40 together, while changing the position of the limiting body 314 can only adjust the vertical position of the second tool 332. It also includes:

[0087] An injection unit 32 is disposed on the machining unit 31. In the machining state, the injection unit 32 is driven to provide a clean airflow that is injected into the upper chamber with a first driving force or a second driving force. The workpiece assembly 40 includes a bushing unit 41 and a machining chamber 42 located inside the bushing unit 41 and having an opening. Based on the alignment of the first tool 331 with the second machining position, the machining chamber 42 is divided into an upper chamber and a lower chamber.

[0088] Furthermore, the airflow enters from the upper chamber, causing machining debris to fall from the upper chamber into the lower chamber. The accumulation of debris can affect the machining operation of the tool, and the clean airflow keeps the machining chamber 42 clean.

[0089] 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.
