Description

Technical Field

[0001] The utility model relates to the technical field of workpiece clamping devices, in particular to a tooling structure used for processing thin-walled parts. Background Art

[0002] Thin-walled components are widely used in aerospace, automotive, and other fields due to their lightweight structure, low weight, and high strength. However, due to their thin wall thickness, thin-walled components are prone to deformation, vibration, and lack of precision during processing, making them difficult to manufacture.

[0003] For example, Chinese patent CN220240772U discloses a clamping tooling structure for machining mechanical parts. Although it provides a tooling structure for clamping parts, it is not suitable for machining thin-walled parts and is very likely to cause damage to the parts and protect the surface quality.

[0004] Furthermore, conventional tooling structures typically employ rigid clamping, locking thin-walled parts in place through mechanical clamping or fixtures. However, thin-walled parts are relatively fragile, and rigid clamping can easily compress their surfaces, leading to surface degradation or workpiece deformation. Furthermore, due to the lack of adequate support for thin-walled parts, vibrations generated by the machining process can easily cause workpiece displacement, further compromising machining accuracy and even damaging the workpiece.

[0005] In addition, the traditional existing technology also has the following defects:

[0006] 1. Extrusion and surface damage: Mechanical clamping methods can easily cause thin-walled parts to be subjected to excessive clamping force, resulting in their surface being squeezed, thereby affecting the surface quality of the finished product.

[0007] 2. Workpiece deformation: Due to the thin wall thickness of thin-walled parts, there is a lack of sufficient support during the processing, and they are prone to deformation under clamping and processing pressure, making it difficult to ensure processing accuracy.

[0008] 3. Vibration-induced displacement and damage: The vibration generated by high-speed operation of processing equipment can easily cause displacement or displacement of thin-walled parts, resulting in inaccurate positioning and even damage to the workpiece. This is especially true in high-vibration environments, where the impact of vibration on the workpiece is more significant.

[0009] The present invention is designed to solve the common problems in this field such as surface quality damage caused by the clamping process, lack of support for processed parts, inconvenience in turning the workpiece, lack of shock-absorbing measures in the support process, etc. Utility Model Content

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] The following combination Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6The present invention is further described in the following embodiments. This embodiment provides a tooling structure for machining thin-walled parts 1, comprising a clamping member, a steering member, a protective member, and a position-limiting support member. The steering member and the protective member are disposed on the clamping member. The protective member flexibly contacts the part to be machined. The protective member is disposed on the steering member, and the steering member is used to adjust the machining angle of the part. The clamping member clamps the part from the circumferential side of the part.

[0042] Wherein, the position-limiting support member is arranged on the clamping member and provides position-limiting protection for the parts.

[0043] In this embodiment, if Figure 2 As shown, the part is configured as a thin-walled barrel structure.

[0044] Furthermore, the protective component includes a protective seat 13, a protective airbag 7, an electronic deflation valve 12, an air pump 15, an inflation pipe 16, and at least one α pressure sensor. One end of the inflation pipe 16 is connected to the protective airbag 7, and the other end of the inflation pipe 16 is connected to the air pump 15 to form a protective part. The protective part is arranged on one side end surface of the protective seat 13, the electronic deflation valve 12 is arranged on the protective airbag 7, and at least one α pressure sensor is arranged at equal intervals on the contact end surface of the protective airbag 7 and the part.

[0045] The protective seat 13 is provided with a hidden cavity, and the protective airbag 7 is hidden in the hidden cavity of the protective seat 13 when not triggered.

[0046] In this embodiment, the electronic deflation valve 12 discharges the gas in the protective airbag 7 based on the control signal, thereby releasing the contact state of the protective airbag 7 with the thin-walled part 1;

[0047] The air pump 15 is in the triggering stage. The air pump 15 blows external gas into the protective airbag 7 through the inflation pipe 16, causing the protective airbag 7 to inflate and swell, thereby contacting the surface of the thin-walled part 1. When at least one α pressure sensor detects that the contact pressure between the protective airbag 7 and the thin-walled part 1 falls within a set monitoring range, the air pump 15 stops inflating the protective airbag 7; otherwise, the protective airbag 7 continues to be inflated.

[0048] At the same time, through the flexible contact of the protective component on the thin-walled part 1, the surface quality of the thin-walled part 1 is effectively protected, ensuring that the entire device has the advantages of good surface quality protection effect, high clamping stability and high processing accuracy of the thin-walled part 1.

[0049] Furthermore, the steering component includes a steering seat 17, a steering drive mechanism 18, a fixed seat 22, an identification probe 20, and at least two angle marking members 21. The steering seat 17 is provided with a connecting rod 19 and one end of the connecting rod 19 is connected to the steering seat 17. The other end of the connecting rod 19 is hinged to one side end face of the fixed seat 22 to form a hinged portion. A steering gear is nested on the connecting rod 19. The steering drive mechanism 18 is arranged on the fixed seat 22 and is driven and connected to the steering gear. At least two angle marking members 21 are arranged on the end face of the fixed seat 22 facing the steering seat 17 and are distributed at equal intervals along the circumference of the hinged portion. The identification probe 20 is arranged on the steering seat 17 and is arranged towards the end faces of at least two angle marking members 21.

[0050] During the rotation process, the rotating member drives the protective member and the thin-walled part 1 to rotate to meet the processing needs of different positions of the thin-walled part 1;

[0051] Specifically, the protection seat is connected to the steering seat and rotates along with the rotation of the steering seat;

[0052] During the rotation process, the identification probe 20 collects the position of the angle marker 21 in real time, thereby accurately controlling the rotation angle of the steering seat 17;

[0053] At the same time, the steering drive mechanism 18 compares the rotation angle obtained based on the identification probe 20 with the required rotation angle. If it is inconsistent with the required rotation angle, the rotation drive mechanism continues to rotate the steering seat 17 until the required rotation angle is consistent with the required angle.

[0054] In this embodiment, the protective component and the steering component cooperate with each other to improve the adaptive adjustment capability of the angle of the thin-walled part 1, ensuring that the entire device has the advantages of controllable steering range, good contact force control capability and good part protection effect.

[0055] Furthermore, the clamping member includes a clamping rod 6, an ejection rod 10, an ejection drive mechanism, a sliding rail, and a clamping seat 3. The clamping seat 3 is provided with at least three clamping grooves 5, and the three clamping grooves 5 are evenly spaced along the symmetrical center axis of the clamping seat 3. The sliding rails are respectively arranged in the three clamping grooves 5 and extend along the length direction of the three clamping grooves 5. The clamping rod 6 is respectively arranged in at least three clamping grooves 5, and one end of the clamping rod 6 is slidably connected to the clamping groove 5 to form a sliding portion, and the other end of the clamping rod 6 extends vertically toward a side away from the clamping groove 5. One end of the ejection rod 10 is connected to the sliding portion, and the other end of the ejection rod 10 is driven and connected to the ejection drive mechanism to form a pushing portion, and the pushing portion is arranged on one end portion of the clamping groove 5.

[0056] In addition, if Figure 6 As shown, the fixing seat is connected to an end of the clamping rod away from the sliding portion.

[0057] Furthermore, the clamping seat 3 is set to be cylindrical, and at least three clamping grooves 5 provided on the clamping seat 3 are distributed at equal intervals along the axis of the symmetry center of the clamping seat 3, such as Figure 4 As shown (in the figure, three clamping grooves 5 are set and the distance between each clamping groove 5 is 60°).

[0058] The protective member and the steering member are arranged on the clamping seat 3 and move along with the movement of the clamping seat 3;

[0059] In this embodiment, the clamping seat 3 is pushed by the ejection drive mechanism to move along the groove direction of the clamping groove 5, thereby approaching the axis position of the symmetry center of the clamping seat 3, thereby achieving contact with the outer wall of the thin-walled part 1, thereby achieving clamping of the thin-walled part 1;

[0060] At the same time, if Figure 4 As shown, the clamping seat 3 provided with at least three clamping grooves 5 clamps the protective member and the steering member to the thin-walled part 1 from the axial side of the symmetry center of the clamping seat 3;

[0061] Furthermore, the lengths of the three clamping grooves 5 are adapted to the circumference of the part to be processed. Specifically, the clamping range of the thin-walled part 1 needs to be adapted to the movement range allowed by the clamping grooves 5, thereby meeting the clamping requirements for the thin-walled parts 1 of different circumferences.

[0062] In this embodiment, the thin-walled part 1 is clamped by the clamping member so that the thin-walled part 1 can be clamped from multiple directions, ensuring the stability of the clamping of the cold thin-walled part 1, while also taking into account the effective absorption of vibration, thereby improving the uniform force on the thin-walled part 1 and improving the overall accuracy and surface quality of the thin-walled part 1.

[0063] Furthermore, the position-limiting support member includes a movable seat 8, an extension rod 14, an extension drive mechanism, a position-limiting airbag 9, an electric pump, an adjustment air valve 11, an air supply pipe, and at least one β pressure sensor. One end of the air supply pipe is connected to the electric pump to form an air supply portion, and the other end of the air supply pipe is connected to the position-limiting airbag 9. The adjustment air valve 11 is arranged on the position-limiting airbag 9. At least one β pressure sensor is arranged on the contact end surface with the part. One end of the extension rod 14 is connected to the movable seat 8, and the other end of the extension rod 14 is driven and connected to the extension drive mechanism to form an extension portion. The extension portion is arranged at the axis of the symmetry center of the clamping seat 3.

[0064] The air supply portion and the limiting airbag 9 are hidden and arranged on the movable seat 8 .

[0065] In this embodiment, the position-limiting support member is arranged at the axis of the symmetry center of the clamping seat 3, and the axis of the extension rod 14 is coaxial with the axis of the clamping seat 3;

[0066] Specifically, in the process of the clamping member, the steering member and the protective member contacting the outer wall of the thin-walled part 1, the limiting support member extends into the inner cavity of the thin-walled part 1 and cooperates with the protective member to clamp and limit from both sides of the inner and outer walls of the thin-walled part 1 to achieve reliable clamping of the thin-walled part 1.

[0067] In this embodiment, the protective component and the limiting support component cooperate with each other to synchronously clamp the inner cavity and outer wall of the thin-walled part 1, thereby improving the surface quality of the thin-walled part 1 and ensuring the stability and reliability of the processing of the entire thin-walled part 1.

[0068] At the same time, the limiting support member limits the thin-walled part 1, alleviates the vibration and deviation of the thin-walled part 1, improves the processing accuracy of the thin-walled part 1, prevents deformation or damage caused by excessive local force, and improves the adaptability of the tooling and the processing quality of the workpiece.

[0069] Furthermore, the limiting airbag 9 and the protective airbag 7 are made of an inflatable, deformable, and wear-resistant material. The material of the limiting airbag 9 needs to have both deformability and wear resistance, thereby ensuring greater stability in the limiting support of the thin-walled component 1 and preventing burrs on the thin-walled component 1 from puncturing the limiting airbag 9.

[0070] Furthermore, the extending position of the extending rod 14 is arranged relative to the clamping position of the protective component on the part.

[0071] Specifically, the extending rod 14 adjusts the position of the limiting airbag 9 under the drive of the extending drive mechanism, thereby limiting and supporting the thin-walled part 1 in the inner cavity of the thin-walled part 1. At the same time, the protective airbag 7 clamps the thin-walled part 1 from the outer wall of the thin-walled part 1, and sets the contact position of the limiting airbag 9 and the protective airbag 7 to a relative position at the same height, which can improve the stability of the thin-walled part 1, prevent deformation or damage caused by excessive local force, and improve the adaptability of the tooling and the processing quality of the workpiece.

[0072] In addition, the tooling structure also includes a central processing unit, which controls the connection of the clamping member, steering member and limiting support member, and centrally controls the clamping member, steering member and limiting support member based on the central processing unit, so as to clamp the thin-walled part 1 to be processed, so as to improve the protection of the entire device on the surface quality of the thin-walled part 1.

[0073] Furthermore, the position-limiting support member further includes an extension detection member, which monitors the extension length of the extension rod 14 .

[0074] Among them, a closed-loop control system is formed between the extension detection part, the extension drive mechanism, the extension rod 14 and the central processing unit. When the extension detection part detects that the extension length of the extension rod 14 is inconsistent with the set length, the central processing unit controls the extension drive mechanism to drive the extension rod 14, so that the extension rod 14 performs an extension operation, thereby changing the position of the limiting airbag 9, and further realizing precise control of the support position of the thin-walled part 1.

[0075] In this embodiment, the extension rod 14 and the ejection rod 10 are both retractable structures, and can achieve retractable motions under the drive of the extension drive mechanism and the ejection drive mechanism.

[0076] By integrating a protective airbag (7) and a position-limiting support structure into the clamping structure, the problem of workpiece deflection and surface damage caused by vibration during thin-walled workpiece machining is effectively resolved. In particular, the position-limiting support structure's vibration damping and support functions in vibrating environments ensure workpiece machining stability and high surface quality, making it suitable for high-precision thin-walled workpiece machining scenarios.

[0077] At the same time, the clamping components and limit supports work together. The clamping components provide uniform flexible protection and clamping through airbags, while the limit supports provide rigid support and limit the key positions of the workpiece, ensuring the overall stability of the workpiece during processing. Under high vibration conditions, the limit supports can effectively absorb and prevent vibration energy from being transmitted to the workpiece, reducing the risk of displacement.

[0078] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
