Description

Technical Field

[0001] This utility model relates to the field of pressure head machine technology, and in particular to a multi-station positioning pressure head machine for processing high-strength fastener pressure heads. Background Technology

[0002] In the machining of fastener indenters, traditional equipment typically uses fixed or manually adjustable fixtures to position and clamp the workpiece. These types of equipment generally suffer from poor adaptability, making it difficult to quickly adapt to fastener indenters of different sizes and specifications. Changing fixtures or adjusting positioning consumes a significant amount of auxiliary time, severely restricting production efficiency.

[0003] Furthermore, traditional single-station or simple multi-station designs often fall short in terms of clamping accuracy and stability, which can easily lead to workpiece displacement or vibration during processing. This not only affects the consistency of processing quality but may also increase the scrap rate, making it difficult to meet the stringent requirements of high-strength fasteners for processing accuracy and batch production stability. Therefore, a multi-station positioning press head machine for processing high-strength fastener press heads is proposed to solve the above problems. Utility Model Content

As a further description of the above technical solution: The rotating bar constrains the rotation of the processing seat to prevent it from detaching from the entire device; As a further description of the above technical solution: Pressing the locking block stretches the multiple springs. At this time, the extrusion head is slid into the extrusion block, which facilitates quick replacement according to different workpiece sizes. As a further description of the above technical solution: When the pressing of the locking block stops, the multiple springs are stretched, pulling the locking block to engage with the inside of the extrusion head, thus achieving the purpose of quick replacement.

[0006] This utility model has the following beneficial effects: 1.

[0017] Reference Figures 1 to 3 This utility model provides an embodiment of a multi-station positioning press head machine for processing high-strength fastener press heads, including a worktable 1, which is designed as the basic platform and support structure of the entire equipment. A steering shaft 2 is rotatably connected to the outside of the worktable 1, which is designed as the core transmission hub. A cylinder 3 is fixedly connected inside the steering shaft 2, which is designed to provide stable and controllable linear thrust and pull for the entire clamping action. A push block 4 is fixedly connected to the drive end of the cylinder 3, which is designed to receive and transmit linear thrust. Its internal rotational connection is the key node for motion form conversion. A rotation angle 5 is rotatably connected inside the push block 4, which is designed to accurately convert linear push and pull motion. A processing seat 6 is fixedly connected to the outside of the rotation angle 5, which is designed as the core component that directly supports and positions the workpiece.

[0018] Multiple limiting blocks 7 are fixedly connected to the outside of the worktable 1. This design serves as a mechanical limit and guide to prevent deviation of its movement trajectory. A rotating bar 8 is fixedly connected to the outside of the machining seat 6. This design ensures that the machining seat 6 rotates stably on a fixed axis without detachment or jamming. The cylinder 3 pushes the push block 4, thereby controlling the rotation angle 5 and causing the machining seat 6 to rotate within the worktable 1 under the constraint of the external rotating bar 8, thus controlling the machining seat 6 to rotate back and forth within the worktable 1. Multiple sliding grooves 14 are opened inside the machining seat 6. This design serves as the geometric basis for converting rotational motion into radial linear motion. The rotating bar 8 constrains the rotation of the machining seat 6, preventing... Separated from the entire device, multiple sliding grooves 14 are slidably connected to sliding columns 9, which are designed as intermediate components for power transmission. One end of the sliding column 9 is fixedly connected to an extrusion block 10, which is designed as a direct output element of clamping force. Under the drive, it moves towards the center and together forms a clamping cavity to center and clamp the workpiece. Multiple limit blocks 7 are fixedly connected to the outside of the worktable 1 to restrict the sliding path of the extrusion block 10 and prevent deviation. When the processing seat 6 rotates, the multiple sliding grooves 14 inside drive the sliding columns 9 to slide, thereby controlling the multiple extrusion blocks 10 to clamp the fastener pressure head axially. The extrusion block 10 has a replacement component inside that facilitates the replacement of fastener pressure heads of different sizes.

[0019] Reference Figure 4 , Figure 5 The replacement components include extrusion heads 11, which are designed as vulnerable or standard parts that directly contact the workpiece. The interiors of multiple extrusion heads 11 are slidably connected to the interiors of extrusion blocks 10. The interiors of multiple extrusion blocks 10 are slidably connected to locking blocks 12, which are designed to automatically lock into the grooves of the extrusion heads 11 under the action of springs 13, thereby achieving quick locking and fixing of the extrusion heads 11.

[0020] Multiple springs 13 are externally fixed to the locking block 12. This design is intended to provide continuous elastic force to ensure that the locking block 12 can reliably lock the extrusion head 11 in the non-operating state, preventing it from loosening. Pressing the locking block 12 stretches the multiple springs 13. At this time, the extrusion head 11 is slid into the extrusion block 10, which facilitates quick replacement according to different workpiece sizes. When the locking block 12 is stopped, the multiple springs 13 stretch, pulling the locking block 12 to engage with the inside of the extrusion head 11, achieving the purpose of quick replacement.

[0021] Working Principle: This multi-station positioning press head machine for high-strength fastener press head processing is designed with a core system of precision mechanical linkage to achieve automatic, rapid, and accurate positioning and clamping of press heads of different specifications. The entire machine's workflow begins with the steering shaft 2 on the worktable 1, which serves as the power hub. This steering shaft 2 is directly connected to the output end of the cylinder 3, forming the primary drive unit of the equipment. When the processing task starts, the piston rod of the cylinder 3 extends or retracts after receiving a control signal, thereby driving the push block 4 connected to it to move linearly. The linear motion of the push block 4 is converted into the rotational motion of the processing seat 6 through a cleverly designed rotation angle 5. Specifically, when the push block 4 moves forward or backward, it acts on the rotation angle 5, forcing the processing seat 6 to rotate around its axis within the worktable 1 at a specific angle. During this process, the rotating bar 8 set on the outside of the processing seat 6 plays a crucial role in constraint and guidance. It acts like a track limiter, ensuring that the rotational motion of the processing seat 6 is smooth and controllable, strictly following the predetermined trajectory, effectively preventing it from disengaging or jamming during rotation, and ensuring the reliability of the entire transmission chain. The most ingenious part lies in how the rotation of the machining base 6 is converted into a clamping force on the workpiece. The interior of the machining base 6 is not a solid structure, but rather has multiple radially arranged sliding grooves 14. Each sliding groove 14 contains a freely sliding column 9, which is connected to multiple pressing blocks 10. When the machining base 6 rotates, since its base is fixed, the rotational motion forces a change in the positional relationship of the multiple sliding grooves 14, thereby driving each sliding column 9 to slide synchronously inward (towards the axis) or outward along the trajectory of the sliding groove 14. The sliding of the sliding column 9 directly drives the pressing block 10 fixed to it to move radially, thereby enabling multiple pressing blocks 10 to move synchronously towards the axis, forming a uniform enclosure and clamping of the fastener pressure head placed in the center. To ensure the absolute stability and reliability of the clamping process and to prevent the pressing block 10 from radially shifting or twisting during movement, multiple limiting blocks 7 are fixedly connected to the outside of the worktable 1. These limiting blocks 7 are precisely distributed along the movement path of the extrusion blocks 10, acting like baffles beside a track. They rigidly restrict and guide the sliding path of the extrusion blocks 10, ensuring the synchronicity and linearity of the movement of all extrusion blocks 10, thereby controlling the clamping accuracy to an extremely high level. This linkage design enables the machine to automatically adapt to fastener pressure heads of different sizes with excellent performance. Because multiple extrusion blocks 10, under the precise linkage of the slide groove 14 and the slide column 9, always synchronously contract towards the center or expand outward, their clamping range can be steplessly adjusted according to the actual diameter of the object, achieving true automated centering and completing fast and accurate positioning without any manual adjustment.The benefits of this design are comprehensive: the multi-station positioning capability significantly improves processing efficiency, allowing multiple workpieces to be processed simultaneously; the precise and flexible clamping mechanism ensures a high degree of consistency in the size and shape of the pressure head, greatly reducing the scrap rate; the fully automated operation not only reduces labor costs but also alleviates the labor intensity of workers, making it particularly suitable for the high-volume, continuous production needs of high-strength fasteners; in addition, the entire structure is compact, rigid, and durable, and the maintenance and replacement of components are simple, effectively extending the service life of the equipment and resulting in significant overall economic benefits.

[0022] The extrusion head 11 replacement component of this multi-station positioning extrusion head machine for high-strength fastener extrusion head processing is designed around the principle of quickly and reliably adapting to workpieces of different specifications, reflecting a highly modular and user-friendly operation concept. When the processing task requires switching to a fastener extrusion head of different size or contour, the replacement process begins with the operator pressing the locking block 12. After being pressed, the locking block 12 slides linearly along the preset slide inside the extrusion block 10. This action directly applies pressure to the multiple springs 13 installed in the slide, causing the springs 13 to undergo elastic deformation and be compressed, thus storing the necessary elastic potential energy for the subsequent reset of the locking block 12. While the locking block 12 is pressed and the springs 13 are compressed, the interlocking relationship between it and the original extrusion head 11 is released. The locking state originally achieved by the locking block 12 engaging the corresponding groove of the extrusion head 11 disappears, allowing the original extrusion head 11 to smoothly slide out of the internal cavity of the extrusion block 10 under the action of gravity or slight external force, completing the disassembly. When installing a new extrusion head 11, the operator aligns the selected extrusion head 11, which has a specific working size or profile, with the internal cavity entrance of the extrusion block 10 and slides it in. During the sliding process, the guide structure on the outer surface of the extrusion head 11 ensures that it can smoothly reach the predetermined installation position. When the extrusion head 11 moves to the position where its internal groove aligns with the corresponding position of the locking block 12, the operator releases the pressure on the locking block 12. At this time, the multiple compressed springs 13 lose their external pressure, and their stored elastic potential energy is released instantaneously, which is converted into kinetic energy to drive the locking block 12 to move in the opposite direction, pushing the locking block 12 to reset precisely and quickly. Driven by its springs 13, the reset locking block 12 reliably locks into the corresponding groove inside the new extrusion head 11. This "locking block 12-groove" interlocking mechanism forms a firm mechanical connection between the extrusion head 11 and the extrusion block 10, realizing the rapid locking of the extrusion head 11. In summary, this replacement assembly, through the ingenious cooperation of the locking block 12, the spring 13, and the groove on the pressing head 11, achieves rapid switching between the connection states of the pressing head 11 and the pressing block 10. This design not only allows the equipment to flexibly adapt to the processing needs of fastener pressing heads of different sizes and shapes, significantly improving the equipment's versatility and production line efficiency, and reducing downtime required for tooling changes, but also features a simple structure, reliable operation, and convenient maintenance, reducing the labor intensity and skill requirements of operators.
