Description

Technical Field

[0001] The present invention relates to the technical field of processing machine tools, and particularly to a screw crimping device with automatic position change and retention and an automatic position change and retention method. Background Art

[0002] Due to their excellent connection performance, special-shaped connectors have been widely used in fields such as automobiles, aerospace, etc.

[0003] During the processing of special-shaped connectors, multiple processes are usually required, including but not limited to chamfering, hole drilling, tapping, etc. To improve processing efficiency, rotary multi-station processing machine tools are mostly used in actual production. This type of machine tool can perform precise corresponding operations on parts by setting processing modules above different processing stations. During the processing, the disk carrying the parts will rotate relative to each processing module, and the parts will be sequentially transported directly below the processing module. This process poses extremely high requirements on the rotation angle and positioning accuracy of the disk. If the disk rotates and there is a misalignment between the processing module and the parts on the disk, it will directly affect the processing accuracy between the processing module and the parts, and may even lead to the accumulation of processing errors, affecting the quality of the final product.

[0004] However, in existing rotary multi-station processing machine tools, the rotation of the disk usually relies on a self-locking motor for driving. Although the self-locking motor can ensure the stability of rotation to a certain extent, there are still certain errors in its rotation accuracy. This error will cause a misalignment between the parts and the processing module after the disk switches stations, thus affecting the processing accuracy. Moreover, the force applied during the processing will also impact the self-locking motor, affecting the motor accuracy and service life. Especially in this high-precision processing scenario, this error may be further amplified, resulting in unstable processing quality and even increasing the scrap rate. Summary of the Invention

One end of the first spring is connected to the end of the transverse shaft, and one end is connected to the connecting plate; The abutting wheel cooperates with a driving member provided on the fixed ring and can press the workpiece when the rotating disk rotates.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0031] Please refer to Figures 1 to 11 , in the embodiment of the present invention, for the automatic position-changing and holding screw pressing device, there is a box body 1, and a rotating disk 2 is arranged in the box body 1. Specifically, the rotating disk 2 is rotatably installed on the supporting plate 101 in the box body 1; It further includes: a locking disk 21, an elastic structure, a driving component and a follow-up component.

[0032] The driving component is arranged in the box body 1, and the driving component can drive the rotating disk 2 to rotate. The driving component includes a driving shaft 10 fixedly connected coaxially with the rotating disk 2, and a ratchet wheel 11 is fixedly installed on the driving shaft 10; The driving component further includes an electric telescopic rod 9 arranged on the base box body 1. A ratchet plate 12 is fixed on the moving end of the electric telescopic rod 9. A plurality of pawls 1201 adapted to the ratchet wheel 11 are rotatably installed on the ratchet plate 12. Specifically, a torsion spring (not shown in the figure) is arranged at the rotation connection of the pawl 1201 and the ratchet plate 12. The torsion spring supports the pawl 1201, so that when the ratchet plate 12 moves forward, the pawl 1201 can engage with the ratchet wheel 11 and drive the ratchet wheel 11 to drive the drive shaft 10 and the rotating disk 2 to rotate. When the ratchet plate 12 moves backward, the pawl 1201 can yield to avoid the reverse rotation of the drive shaft 10. Further, in order to improve the stability of the rotating disk 2 when the ratchet plate 12 moves backward, a damping sleeve is arranged at the rotation connection of the drive shaft 10 and the supporting plate 101.

[0033] In this embodiment, in the initial state, the elastic structure cooperates with the locking disk 21 to axially lock the rotating disk 2. This design ensures the position stability of the rotating disk 2 and its associated components during the processing, thus significantly improving the processing accuracy and position accuracy of each component. In this way, the system can maintain high-precision positioning in the processing state and avoid processing errors caused by component displacement.

[0034] When it is necessary to switch the working position of the rotating disk 2, by controlling the movement of the electric telescopic rod 9, the ratchet plate 12 reciprocates horizontally. When the ratchet plate 12 moves to the position where the pawl 1201 engages with the ratchet wheel 11, the two cooperate to drive the drive shaft 10 to rotate, so as to realize the rotation of the rotating disk 2 and complete the switching of the working position. This design ensures the reliability and efficiency of the rotation action through the directness of mechanical transmission.

[0035] Further, after the rotating disk 2 rotates a certain angle, the elastic structure can abut against the locking disk 21 again. When the rotating disk 2 rotates to a predetermined angle, the elastic structure will automatically reset and lock with the locking disk 21 again, so as to ensure the position stability of each working position after the working position is switched.

[0036] In addition, this design realizes the automatic switching of the rotating disk 2 through the precise control of the electric telescopic rod 9, reduces the need for manual intervention, improves the operation efficiency. At the same time, the modular design of the system makes maintenance and debugging more convenient, further enhancing the overall use experience and applicability.

[0037] It should be noted that when the ratchet plate 12 moves, it will first drive the elastic structure to move through the follower assembly, so that the elastic structure is separated from the locking disk 21, and then the pawl 1201 on the ratchet plate 12 will engage with the ratchet wheel 11 to drive the rotating disk 2 to rotate. When the elastic structure cooperates with the locking disk 21 again to achieve locking, the ratchet plate 12 moves backward.

[0038] Please refer toFigures 3 to 4 , Figure 9 , Figure 10 , the follower assembly is connected to the ratchet plate 12. Before the driving assembly drives the rotating disk 2 to rotate, the follower assembly can cooperate with the one-way deflecting member 22 provided on the elastic structure to separate the elastic structure from the limiting groove 2101.

[0039] The follower assembly includes a guiding frame 16 mounted on the box body 1. A guiding groove is provided on the guiding frame 16, and a follower shaft 14 is rotatably arranged in the guiding groove. The follower shaft 14 is connected to the ratchet plate 12 through a hinge rod 13. Wherein, the guiding groove includes an inclined groove 1601 provided on the guiding frame 16 and a horizontal groove 1602 connected to the head and tail ends of the inclined groove 1601.

[0040] A contact roller 15 coaxial with the follower shaft 14 and in contact and cooperation with the one-way deflecting member 22 is provided on the follower shaft 14.

[0041] In this embodiment, the reciprocating horizontal movement of the ratchet plate 12 realizes the unlocking, rotation, and re-locking of the rotating disk 2 through a mechanical linkage mechanism, ensuring the high-precision positioning and stability of the rotating disk 2 during the processing; specifically, when the ratchet plate 12 moves forward, the connection end thereof with the hinge rod 13 moves forward accordingly, and the other end of the hinge rod 13 is connected to the follower shaft 14. The follower shaft 14 is located in the horizontal groove 1602. During the forward movement of the ratchet plate 12, the follower shaft 14 slides horizontally along the horizontal groove 1602, and at the same time drives the contact roller 15 to contact the one-way deflecting member 22. At this time, the one-way deflecting member 22 is laterally displaced under the action of the contact roller 15, so that the elastic structure is separated from the locking disk 21, and the rotating disk 2 is unlocked, preventing the rotating disk 2 from rotating when the elastic structure is not separated from the locking disk 21, resulting in interference.

[0042] As the rotating disk 2 starts to rotate, the follower shaft 14 enters the inclined groove 1601 and moves along it, gradually separating from the one-way deflecting member 22. After the separation of the two, the elastic structure quickly resets under the action of its own elastic force and re-contacts the circumferential surface of the locking disk 21. When the rotating disk 2 rotates to a predetermined angle, the elastic structure is precisely matched with the locking disk 21, and the axial locking of the rotating disk 2 is realized again. This locking mechanism not only improves the stability of the rotating disk 2 after rotating a predetermined angle, but also ensures the precise alignment of each station, thus significantly improving the processing accuracy and system reliability.

[0043] When the ratchet plate 12 moves in the opposite direction, the follower shaft 14 moves in the opposite direction, and the abutment roller 15 abuts against the one-way deflection member 22 again, causing the one-way deflection member 22 to deflect. As the follower shaft 14 returns to the initial position, the one-way deflection member 22 automatically resets under the action of gravity and returns to the initial state. This design ensures that the next time the rotating disk 2 is driven to move, the entire system can repeat the above process to maintain the consistency and stability of the action. In addition, through the gravity reset mechanism of the one-way deflection member 22, the dependence on additional power sources is reduced, the system structure is simplified, and the response speed and operating efficiency of the system are improved.

[0044] In general, the design achieves efficient unlocking, rotation and locking of the rotating disk 2 through the clever coordination of the mechanical structure, which not only improves the stability and processing accuracy of the system, but also improves the durability and ease of use of the system by reducing component wear and simplifying the operating process. This design is particularly suitable for automated processing scenarios that require frequent switching of workstations, and can significantly improve production efficiency and product quality.

[0045] See also Figure 4 , Figure 6 , Figure 9 , the locking plate 21 is fixedly connected to the rotating plate 2, and a plurality of limiting grooves 2101 are provided on the locking plate 21; The elastic structure cooperates with the limiting groove 2101 to axially lock the rotating disk 2. The elastic structure includes a hysteresis sleeve 17 fixedly mounted on the box body 1, a telescopic rod 19 is slidably mounted in the hysteresis sleeve 17, an engaging wheel 20 is rotatably mounted on one end of the telescopic rod 19, and the other end is connected to the inner wall of the hysteresis sleeve 17 through a second spring 18, and the engaging wheel 20 is adapted to the limiting groove 2101; The one-way deflection member 22 is rotatably connected to the telescopic rod 19 , wherein the telescopic rod 19 is provided with an abutment surface 1901 , and one end of the one-way deflection member 22 close to its rotation axis is respectively provided with an arc surface and a right-angle abutment portion 2201 .

[0046] In the initial state, the second spring 18 is in a compressed state, which makes the telescopic rod 19 tend to move toward the locking disk 21. The extension line of the telescopic rod 19 along its length direction passes through the center of the locking disk 21, ensuring that the engaging wheel 20 is accurately embedded in the limiting groove 2101 and no component force is generated. This design enables the locking disk 21, the drive shaft 10 and the rotating disk 2 to be reliably locked in the initial state, thereby significantly improving the stability of the rotating disk 2. During the processing, this locking mechanism can ensure high-precision positioning between each processing module and the parts to be processed, avoiding processing errors caused by slight displacements of the rotating disk 2, thereby improving the overall processing quality.

[0047] When the ratchet plate 12 moves forward, the follower shaft 14 drives the abutting roller 15 to abut against the one-way deflecting member 22. At this time, the right-angle abutting portion 2201 on the one-way deflecting member 22 precisely cooperates with the abutting surface 1901 on the telescopic rod 19, preventing the one-way deflecting member 22 from deflecting relative to the telescopic rod 19. This design ensures that the acting force of the abutting roller 15 can be directly transmitted to the telescopic rod 19, causing it to move towards the second spring 18, further compressing the second spring 18, and at the same time separating the engaging wheel 20 from the limiting groove 2101, realizing the unlocking of the rotating disk 2. This unlocking mechanism is simpler and more efficient, improving the reliability of the system.

[0048] As the rotating disk 2 starts to rotate, the follower shaft 14 moves along the inclined groove 1601, and the abutting roller 15 undergoes relative displacement relative to the one-way deflecting member 22. After they are separated, the second spring 18 releases its elastic potential energy, driving the engaging wheel 20 towards the locking disk 21. Since the limiting groove 2101 and the engaging wheel 20 are in a misaligned state at this time, the engaging wheel 20 will not be embedded in the limiting groove 2101 again, but rolls and abuts against the circumferential side wall of the locking disk 21. When the rotating disk 2 rotates to a predetermined angle, another limiting groove 2101 coincides with the engaging wheel 20, and the engaging wheel 20 is immediately embedded in the limiting groove 2101, realizing the re-locking of the rotating disk 2. This design ensures that the rotating disk 2 can be quickly locked after rotating to a predetermined angle by shortening the lateral distance between the engaging wheel 20 and the limiting groove 2101, avoiding excessive rotation or locking failure caused by inertia, thereby ensuring the accuracy of the station switching and the integrity of the processing flow.

[0049] In addition, after the rotating disk 2 completes the predetermined locking, the ratchet plate 12 moves in the reverse direction, driving the abutting roller 15 to return to its initial position through the hinge rod 13. When the abutting roller 15 is reset to the horizontal groove 1602, it abuts against the one-way deflecting member 22 again, causing the one-way deflecting member 22 to deflect. When the abutting roller 15 is completely reset to its initial state, the one-way deflecting member 22 automatically resets under the action of gravity and returns to its initial position. This design ensures that the system can maintain a consistent operating effect every time the ratchet plate 12 performs an action, providing a stable structural support for the rotation and locking of the rotating disk 2.

[0050] Overall, through the cooperation of the mechanical structure, this design realizes the efficient unlocking, rotation, and locking of the rotating disk 2, not only improving the stability and processing accuracy of the system, but also enhancing the durability and usability of the system by reducing component wear and simplifying the operation process.

[0051] Please refer to Figure 3 、 Figures 6 to 8A fixing ring 4 coaxial with the rotating disk 2 is detachably installed in the box body 1, and a plurality of groups of groove wheels 3 are equidistantly installed on the rotating disk 2 at a circumferential angle. The groove wheels 3 roll with the circumferential side walls of the fixing ring 4. With the cooperation of the plurality of groups of groove wheels 3 and the fixing ring 4, the longitudinal bounce generated during the circular motion of the rotating disk 2 can be limited, and the position change of the parts to be processed on the rotating disk 2 due to the longitudinal bounce when the rotating disk 2 makes a circular motion can be prevented, thereby improving the stability of the parts to be processed when following the movement of the rotating disk 2 to a certain extent.

[0052] The rotating disk 2 is provided with a plurality of sets of fixing members 201 and pressing members 5 at equal intervals in a circle, and the pressing member 5 is connected with a connecting plate 6 penetrating the rotating disk 2, and an end of the connecting plate 6 away from the pressing member 5 is rotatably mounted with an abutting wheel 7, and the connecting plate 6 is slidably connected with a transverse shaft 23 provided on the rotating disk 2, and a first spring 8 is sleeved on the transverse shaft 23, and one end of the first spring 8 is connected with the end of the transverse shaft 23, and the other end is connected with the connecting plate 6; The abutment wheel 7 cooperates with the driving member arranged on the fixed ring 4, and can press the workpiece when the rotating disk 2 rotates. The driving member includes a plurality of groups of top extension members arranged equidistantly on the circumference of the fixed ring 4, and the top extension members include two groups of symmetrically arranged inclined plates 401. A protrusion 402 is formed at the connection between the two groups of inclined plates 401. When the abutment wheel 7 abuts against the protrusion 402, the fixing member 201 and the pressing member 5 are in a separated state.

[0053] Under the cooperation of the groove wheel 3 and the fixed ring 4, the longitudinal bounce of the rotating disk 2 during the rotation process can be reduced, but it cannot be completely eliminated. Therefore, in this embodiment: In the initial state, the abutment wheel 7 is in abutment with the protrusion 402, the first spring 8 is compressed, and the connecting plate 6 drives the pressing part 5 away from the fixing part 201. This design allows each processing module to directly act on the parts without obstacles and perform predetermined processing actions, ensuring the flexibility and efficiency of the processing process.

[0054] When the rotating disk 2 starts to rotate, the abutment wheel 7 can be switched from the protrusion 402 to the inclined plate 401 until the abutment wheel 7 is separated from the top extension. At this time, the first spring 8 releases its elastic potential energy and drives the pressing piece 5 to move toward the fixing piece 201 to press the parts placed between the two. This pressing mechanism provides stable support for the parts during rotation, prevents the position of the parts from being shifted due to the longitudinal bounce of the rotating disk 2, ensures that the processing module can accurately grasp and process the parts, significantly improves the processing accuracy and reliability, and uses the elastic force provided by the first spring 8 to clamp the workpiece, so that the pressing piece 5 can clamp parts of different specifications in the process of cooperating with the fixing piece 201.

[0055] When the rotating disk 2 rotates to a predetermined angle, the abutting wheel 7 can be guided by the inclined plate 401 to abut against the protrusion 402 again. The pressing member 5 moves away from the fixing member 201, compressing the first spring 8 and at the same time restoring the pressing member 5 to its initial state. This design ensures that when the rotating disk 2 is stationary, the components can be easily moved, facilitating the next operation of the processing module. Through this mechanical linkage, the system realizes seamless switching between static and dynamic states, ensuring both flexibility during the processing and stability during rotation.

[0056] The advantage of this design lies in its simple and efficient mechanical structure. Through the elastic force of the first spring 8 and the cooperation between the abutting wheel 7 and the jacking member, automatic pressing and releasing of the components are achieved. This automated mechanism not only reduces the need for manual intervention but also improves the system's response speed and operation efficiency. In addition, by reducing the displacement of the components during processing, this design effectively avoids processing errors caused by position deviation, thereby improving the overall processing quality and system reliability.

[0057] In practical applications, this design can significantly improve production efficiency while ensuring processing accuracy, providing stable support for the processing of complex components. In this way, the system not only ensures processing accuracy but also improves production efficiency and product quality, providing a reliable solution for modern automated processing.

[0058] As an embodiment of the present invention, an automatic position-changing and holding method is also proposed. Using the automatic position-changing and holding screw pressing device described above, it includes: Place the workpiece to be processed on the rotating disk 2 and within the fixing member 201 and the pressing member 5; The driving component operates to separate the elastic structure from the locking disk 21, and then drives the rotating disk 2 to rotate. During the rotation, the elastic structure can abut against the circumferential side wall of the locking disk 21 and lock the rotating disk 2 again when the rotating disk 2 rotates a predetermined angle; When the rotating disk 2 rotates, the driving member cooperates with the abutting wheel 7 to enable the pressing member 5 to move towards the fixing member 201 and, when the rotating disk 2 rotates a predetermined angle, to move the pressing member 5 away from the fixing member 201.
