Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a floating extrusion fixture, component processing equipment and system. Background Technology

[0002] In fields such as industrial automation assembly and precision machining, the press head, as a core actuator, is widely used in key processes such as parts pressing, workpiece docking, and material bonding. Its working accuracy and adaptability directly affect the product assembly qualification rate and equipment operation stability.

[0003] Most conventional pressure heads adopt a rigid structure design, with a fixed and non-adjustable force direction, and can only perform pressure or positioning actions along a preset single axis. In actual production scenarios, due to factors such as workpiece machining errors, tooling positioning deviations, and fluctuations in robot repeatability positioning accuracy, the actual surface of the workpiece to be pressed often has a slight deviation from the pre-set pressure direction of the pressure head, or the force point may shift.

[0004] Because conventional pressure heads lack the ability to compensate for adaptive force direction, they cannot dynamically adjust their posture to match the actual force requirements of the workpiece, which easily leads to localized stress concentration during the pressure application process. This can not only cause damage and deformation to the workpiece surface, but also lead to problems such as incomplete pressing, abnormal clearance between parts, and in severe cases, even equipment jamming, damage to the pressure head or workpiece, reducing production efficiency and product quality stability.

[0005] To address the aforementioned issues, some improvement solutions attempt to achieve limited buffering by adding elastic elements, but these still cannot achieve active adaptation and precise compensation for multi-directional force application, failing to meet the demands of high-precision and high-consistency industrial production. Therefore, developing a pressure head structure capable of adaptively adapting to the direction of force and dynamically eliminating deviations has become crucial for resolving the pain points of existing technologies. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the limitation of the application scenarios of the pressurization structure in the prior art, and to provide a floating extrusion fixture, component processing equipment and system.

[0007] To solve the above-mentioned technical problems, this utility model provides a floating extrusion fixture, which includes: an installation assembly; and an extrusion assembly. The extrusion assembly includes a transmission component, an extrusion component, and an elastic component. The transmission component and the elastic component are located inside the installation assembly, and the elastic component is located between the transmission component and the installation assembly. One end of the transmission component in the length direction is provided with a mating ball head. One end of the extrusion component abuts against the surface of the mating ball head, and the other end protrudes from the installation assembly to extrude an external structure.

[0008] In one embodiment of the present invention, the transmission component further includes a cylinder, with an opening at one end of the cylinder away from the extruder in the length direction. The elastic element passes through the opening and is inserted into the cylinder. In the length direction of the cylinder, the length of the elastic element is greater than the length of the cylinder, so as to abut against the mounting assembly.

[0009] In one embodiment of the present invention, the mounting assembly includes a transmission fixing plate and a pressing fixing block. The transmission fixing plate and the pressing fixing block are fixedly connected, and the centers of gravity of the transmission fixing plate and the pressing fixing block coincide in the length direction of the transmission member. The transmission member is passed through and connected to the transmission fixing plate, and the pressing member is passed through and connected to the pressing fixing block.

[0010] In one embodiment of the present invention, the transmission fixing plate is provided with a limiting protrusion on the side facing the extrusion fixing block. The limiting protrusion protrudes towards the extrusion fixing block. At least two limiting protrusions are respectively provided on opposite sides of the extrusion fixing block, or multiple limiting protrusions are provided around the edge of the extrusion fixing block.

[0011] In one embodiment of the present invention, the transmission fixing plate has a clearance opening extending through its thickness direction at its center, and the docking ball head protrudes through the clearance opening to contact the extrusion member.

[0012] In one embodiment of the present invention, the center of the extrusion fixing block is provided with an installation opening that extends through its thickness direction, and the cross-sectional diameter of the installation opening gradually narrows in the direction away from the transmission fixing plate, and the extrusion member is supported in the installation opening.

[0013] In one embodiment of the present invention, the extrusion member includes a pressure head and a limiting connecting block. The limiting connecting block is configured as a wedge-shaped block that matches the shape of the mounting port and is supported on the side wall of the mounting port. The pressure head is connected to the end of the limiting connecting block away from the transmission fixing plate and extends out of the mounting port.

[0014] In one embodiment of the present invention, the floating extrusion fixture further includes a housing, which is fastened to the edge of the mounting assembly, and the transmission member and the elastic member are both located inside the housing.

[0015] This utility model also provides a component processing equipment, which includes the above-mentioned floating extrusion fixture.

[0016] This utility model also provides a component processing system, which includes the above-mentioned floating extrusion fixture.

[0017] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: This application provides a relatively movable connection platform for the extrusion component and transmission component in the extrusion assembly through the installation component. The extrusion component directly contacts the external structure, and the transmission component can transmit its reverse force to the elastic component, thereby achieving a floating extrusion effect. During this process, the mating ball head can adaptively receive forces from different directions and transmit them to the extrusion component, avoiding local stress concentration caused by force direction deviation between the extrusion component and the external structure. At the same time, it eliminates the extrusion offset problem caused by installation deviation or unevenness of the external structure surface, ensuring the smoothness and fit of the extrusion action, and guaranteeing the accuracy and consistency of the extrusion process.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Example 1:

[0024] See Figures 1 to 4As shown, this embodiment provides a floating extrusion fixture, which includes: an installation assembly 100; and an extrusion assembly 200. The extrusion assembly 200 includes a transmission member 210, an extrusion member 220, and an elastic member 230. The transmission member 210 and the elastic member 230 are located inside the installation assembly 100, and the elastic member 230 is located between the transmission member 210 and the installation assembly 100. One end of the transmission member 210 in the length direction is provided with a docking ball head 212. One end of the extrusion member 220 abuts against the surface of the docking ball head 212, and the other end protrudes from the installation assembly 100 to extrude an external structure.

[0025] This application provides a relatively movable connection platform for the extrusion component 220 and the transmission component 210 in the extrusion component 200 through the installation component 100. The extrusion component 220 directly contacts the external structure, and the transmission component 210 can transmit its reverse force to the elastic component 230, thereby achieving a floating extrusion effect. In this process, the mating ball head 212 can adaptively receive forces from different directions and transmit them to the extrusion component 220, avoiding local stress concentration between the extrusion component 220 and the external structure due to deviation in the direction of force. At the same time, it eliminates the extrusion offset problem caused by installation deviation or unevenness of the external structure surface, ensuring the smoothness and fit of the extrusion action, and guaranteeing the accuracy and consistency of the extrusion process.

[0026] In this embodiment, the mounting component 100 serves as the basic load-bearing structure of the entire floating extrusion fixture. It not only provides a stable space for the transmission component 210 and the elastic component 230, limiting the installation position and range of motion of each component, but also provides a relatively movable connection reference for the extrusion component 200 through its own structural design. This ensures that each component can cooperate in an orderly manner during operation, while also protecting internal components and preventing external impurities from entering, thus ensuring the overall structural stability and service life of the fixture.

[0027] Furthermore, the mounting assembly 100 includes a transmission fixing plate 110 and a pressing fixing block 120. The transmission fixing plate 110 and the pressing fixing block 120 are fixedly connected, and the centers of gravity of the transmission fixing plate 110 and the pressing fixing block 120 coincide in the length direction of the transmission member 210. The transmission member 210 is connected through the transmission fixing plate 110, and the pressing member 220 is connected through the pressing fixing block 120. Among them, the transmission fixing plate 110 serves as the installation and guiding reference for the transmission component 210. It provides stable support for the transmission component 210 through a through-connection, while restricting the transmission component 210 to reciprocate only along its own length direction, preventing it from deviating or shaking during the force process, and ensuring that the force transmission path is accurate and controllable. The extrusion fixing block 120 is specifically adapted to the installation requirements of the extrusion component 220. Its through-connection structure not only ensures the flexibility of the movement of the extrusion component 220, but also effectively constrains the radial displacement of the extrusion component 220, preventing the extrusion component 220 from deviating when contacting the external structure, and ensuring the coaxiality and stability of the extrusion action. The fixed connection design between the transmission fixing plate 110 and the extrusion fixing block 120 forms an integral force-bearing structure. With the center of gravity coinciding in the length direction of the transmission component 210, it can effectively counteract the eccentric torque generated during tooling operation, reduce vibration, and further improve the structural stability and force balance of the entire mounting assembly 100. This provides a reliable structural foundation for the precise floating extrusion of the extrusion assembly 200. Specifically, the transmission fixing plate 110 and the extrusion fixing block 120 can be fixedly connected by means of bonding, bolting, or plugging. This utility model does not impose any specific limitations on this.

[0028] Furthermore, the transmission fixing plate 110 is provided with a limiting protrusion 111 on the side facing the pressing fixing block 120. The limiting protrusion 111 protrudes towards the pressing fixing block 120, and at least two limiting protrusions 111 are respectively provided on opposite sides of the pressing fixing block 120, or multiple limiting protrusions 111 are provided around the edge of the pressing fixing block 120. The limiting protrusion 111 serves as a positioning and limiting structure between the transmission fixing plate 110 and the pressing fixing block 120. Its protruding design towards the pressing fixing block 120 allows it to precisely fit the corresponding side or edge of the pressing fixing block 120. Through at least two opposing protrusions, a bidirectional constraint is formed on the pressing fixing block 120 from the lateral direction, effectively limiting the displacement of the pressing fixing block 120 in the direction perpendicular to the length of the transmission component 210. This prevents relative offset or misalignment between the two during tooling operation due to vibration, force, or other factors, further enhancing the overall structural stability after the transmission fixing plate 110 and the pressing fixing block 120 are connected. Meanwhile, this limiting method ensures that the center of gravity of both components always coincides along the length of the transmission component 210, maintaining the force balance of the mounting assembly 100. This provides a solid guarantee for the precise guidance and smooth movement of the transmission component 210 and the extrusion component 220, preventing the positional deviation of the mounting assembly 100 from affecting the accuracy and reliability of the floating extrusion. In different embodiments, multiple limiting protrusions 111 can be set to form circumferential limiting through a surrounding layout; this utility model does not impose specific limitations in this regard.

[0029] The transmission fixing plate 110 has a clearance opening at its center, extending along its thickness. The docking ball head 212 protrudes through this clearance opening to contact the extrusion member 220. The clearance opening, located at the center of the transmission fixing plate 110 and extending along its thickness, serves to provide a through-channel for the docking ball head 212 at the end of the transmission member 210. This ensures the docking ball head 212 can smoothly pass through the transmission fixing plate 110 and achieve precise contact with the extrusion member 220, creating the necessary conditions for force transmission and angle adaptation between the two. Furthermore, the clearance opening is slightly larger than the structure of the docking ball head 212. This allows the docking ball head 212 to rotate flexibly to adapt to different force directions on the extrusion member 220, while also providing a certain radial limit to the docking ball head 212. This prevents excessive deflection of the transmission member 210 during reciprocating motion, further ensuring the stability of the contact between the transmission member 210 and the extrusion member 220 and the uniformity of force transmission, providing structural support for the precise realization of the floating extrusion effect.

[0030] Correspondingly, the center of the extrusion fixing block 120 is provided with an installation port 121 extending through its thickness direction. The cross-sectional diameter of the installation port 121 gradually tapers away from the transmission fixing plate 110, and the extrusion member 220 is supported in the installation port 121. The installation port 121 serves as the installation and guiding channel for the extrusion member 220, extending through the thickness direction of the extrusion fixing block 120 and providing dedicated space for the reciprocating motion of the extrusion member 220. The design of its cross-sectional diameter gradually tapers away from the transmission fixing plate 110 forms a conical guide structure adapted to the movement of the extrusion member 220. This structure can provide precise support for the extrusion member 220 and, through the limiting effect of the conical inner wall, guide the extrusion member 220 to always move coaxially along the length direction of the transmission member 210, effectively limiting the radial offset of the extrusion member 220 and preventing it from deflecting or jamming when contacting external structures or receiving force feedback. Meanwhile, this shrinkable structural design complements the shape of the extruder 220, which can increase the contact support area between the mounting port 121 and the extruder 220, improve the stability of the movement of the extruder 220, and ensure that the force transmission is more uniform and smooth when the extruder 220 transmits extrusion force or receives reverse force, further ensuring the accuracy and reliability of floating extrusion, and providing a stable guiding foundation for the coordinated work of the extrusion assembly 200 and the mounting assembly 100.

[0031] In this embodiment, the extrusion component 220 is the core execution component that directly contacts the external structure and realizes the extrusion function. One end of it protrudes from the mounting assembly 100 and can accurately act on the external structure to be processed or fixed, transmitting the driving force of the tooling to the target position. The other end abuts against the mating ball head 212, allowing it to be finely adjusted according to the fitting angle of the mating ball head 212 when under force. This ensures the direct effectiveness of the extrusion action and allows it to flexibly adapt to the surface morphology or installation deviation of the external structure, avoiding damage caused by rigid contact.

[0032] Among them, the transmission component 210 plays a key role in force transmission and angle adaptation. Its main structure located inside the mounting assembly 100 can stably transmit the reverse force received by the extrusion component 220 to the elastic component 230, so that the elastic component 230 produces corresponding elastic deformation to form a floating buffer effect. The mating ball head 212 provided at its end is adapted to the extrusion component 220 through spherical contact, which can adaptively receive forces from different directions, eliminate the influence of force direction deviation, ensure uniform and smooth force transmission, and provide reliable support for the fine adjustment of the angle of the extrusion component 220.

[0033] The elastic element 230 is disposed between the transmission element 210 and the mounting assembly 100. As the core functional component for the floating extrusion effect, it has good elastic restoring ability. When the transmission element 210 transmits the reverse force of the extrusion element 220, the elastic element 230 will generate corresponding compression or deformation according to the magnitude of the force. Through the accumulation and release of elastic potential energy, it achieves buffering and shock absorption, avoiding damage to the tooling or external structure caused by rigid impact. At the same time, after the extrusion action is completed, it can push the transmission element 210 and the extrusion element 220 to quickly return to their original positions, preparing for the next extrusion operation and ensuring the continuous and stable operation of the tooling. In this embodiment, the elastic element 230 is preferably an elastic support column. In different embodiments, the elastic element 230 can also be configured as other elastic structures. This utility model does not impose specific limitations on this.

[0034] In this embodiment, the transmission component 210 further includes a cylindrical body 211. An opening is provided at the end of the cylindrical body 211 furthest from the extruder 220 along its length. The elastic member 230 passes through this opening and is housed inside the cylindrical body 211. The length of the elastic member 230 is greater than the length of the cylindrical body 211 along its length, so as to abut against the mounting assembly 100. The cylindrical body 211, as the main load-bearing structure of the transmission component 210, provides a dedicated space for the elastic member 230 to accommodate and limit its movement. The opening at the end furthest from the extruder 220 facilitates quick installation of the elastic member 230 and effectively constrains its radial displacement, preventing displacement or twisting during deformation or reset under stress, ensuring that the elastic member 230 always extends and retracts along the length of the cylindrical body 211. The design of the elastic element 230 being longer than the cylinder 211 is key to achieving elastic contact: when the cylinder 211 moves towards the mounting assembly 100 under the force of the transmission component 210, the portion of the elastic element 230 exceeding the length of the cylinder 211 can form a stable contact with the mounting assembly 100, thereby generating uniform elastic deformation to absorb the reverse force and creating a floating buffer effect; when the external force disappears, the elastic element 230 uses its own elastic potential energy to push the cylinder 211 and the entire transmission component 210 back to their original position, ensuring the cyclic operation of the tooling. Furthermore, this built-in assembly structure not only makes the connection between the elastic element 230 and the transmission component 210 more compact, reducing the overall space occupied by the tooling, but also protects the elastic element 230 from external impurities or damage due to excessive deformation through the enclosure and protection of the cylinder 211, extending its service life and ensuring the stable and reliable transmission of force and elastic buffering function.

[0035] Furthermore, the extrusion member 220 includes a pressure head 221 and a limiting connecting block 222. The limiting connecting block 222 is configured as a wedge-shaped block that matches the shape of the mounting opening 121 and is supported on the side wall of the mounting opening 121. The pressure head 221 is connected to the end of the limiting connecting block 222 away from the transmission fixing plate 110 and extends out of the mounting opening 121. The limiting connecting block 222 adopts a wedge-shaped design that matches the shape of the mounting opening 121, forming a tightly fitting adaptation structure with the concave conical side wall of the mounting opening 121. Stable support is achieved through surface contact, ensuring the secure assembly of the extrusion member 220 in the mounting opening 121. Furthermore, the wedge-shaped surface guides the movement of the extrusion member 220, ensuring it always reciprocates coaxially along the length of the transmission member 210, effectively preventing the extrusion member 220 from skewing, jamming, or radially displacing under force. The pressure head 221, as the actuator that directly contacts the external structure, is connected to the end of the limiting connecting block 222 away from the transmission fixing plate 110 and extends through the mounting port 121. It can accurately transmit extrusion force to the target structure. Its independently designed structure allows for flexible replacement of the appropriate model according to the shape and size of the external structure. Furthermore, the stable cooperation between the limiting connecting block 222 and the mounting port 121 ensures the stability and accuracy of the pressure head 221's extrusion action. Based on this, the positioning function of the wedge structure and the execution function of the pressure head 221 work together to meet the flexibility requirements of the extrusion action. Reliable support and guidance ensure uniform force transmission and smooth operation during floating extrusion, providing core execution guarantees for the precise extrusion effect of the tooling.

[0036] Furthermore, the floating extrusion fixture in this embodiment also includes a housing 300, which is fastened to the edge of the mounting assembly 100. The transmission component 210 and the elastic component 230 are both located inside the housing 300. The housing 300 is fixed to the edge of the mounting assembly 100 by fastening, forming a closed protective space that completely encloses the core functional components such as the transmission component 210 and the elastic component 230. Its primary function is to provide protection and isolation, effectively preventing dust, debris, oil, and other impurities from the external environment from entering the interior. This avoids impurities adhering to the moving surface of the transmission component 210 or the elastic component 230, preventing wear, jamming, or elastic failure of the components, thereby extending the service life of each core component. At the same time, the overall enclosure structure of the housing 300 also provides physical protection for the internal components, preventing damage from external impacts such as collisions and scratches during handling, installation, or operation, thus ensuring the integrity of the fixture structure.

[0037] In summary, this embodiment provides a relatively movable connection platform for the extrusion component 220 and the transmission component 210 in the extrusion component 200 through the installation component 100. The extrusion component 220 directly contacts the external structure, and the transmission component 210 can transmit its reverse force to the elastic component 230, thereby achieving a floating extrusion effect. During this process, the mating ball head 212 can adaptively receive forces from different directions and transmit them to the extrusion component 220, avoiding local stress concentration between the extrusion component 220 and the external structure due to deviations in the force direction. At the same time, it eliminates extrusion offset problems caused by installation deviations or unevenness of the external structure surface, ensuring the smoothness and fit of the extrusion action, and guaranteeing the accuracy and consistency of the extrusion process.
