Description

Technical Field

[0001] This utility model relates to a flanging mechanism, specifically a high-efficiency flanging mechanism for spinning machines. Background Technology

[0002] Traditional spinning machines have insufficient degrees of freedom in the spinning wheel assembly, making it difficult to achieve spatial curvature compensation for the workpiece flanging trajectory. They often use a two-dimensional X and Y plane motion mode to compensate for the workpiece spinning and flanging, which requires a large amount of movement, making the forward and backward movement process cumbersome, resulting in low flanging efficiency and easy to cause flanging angle deviation. Summary of the Invention

[0003] The present invention aims to address the shortcomings of the above-mentioned problems by providing a high-efficiency flanging mechanism for spinning machines that allows for flanging operations close to the workpiece, and quick flanging by compensating for the required tilt angle through rotation when the distance is small.

[0004] The technical solution to the problem that this utility model aims to solve is as follows:

[0005] A high-efficiency flanging mechanism for a spinning machine is characterized by: a rotary drive device in the Z-axis direction disposed on the X and Y-axis composite motion guide rail of the spinning wheel drive module; a rotary seat assembly is installed at the actuating end of the rotary drive device, the rotary seat assembly comprising: an L-shaped base directly or indirectly fixed to the output end of the drive device via a flange coupling, and a spinning wheel assembly disposed at the cantilever end of the L-shaped base.

[0006] Preferably, the drive device is installed at the end of the Y-axis linear slide of the spinning wheel drive module, and the Y-axis linear slide is mounted on the slide rail that makes up the X-axis via a slide block.

[0007] Preferably, the bottom of the L-shaped base is provided with a mounting hole with a positioning notch, and the drive device drives the base to rotate by matching the output shaft with the mounting hole; the rotation axis of the spinning wheel assembly forms an angle compensation with the rotation axis of the L-shaped base body, and the spinning wheel assembly generates a gradual flanging pressure gradient when it is radially fed, thereby achieving an arc-shaped flanging effect when the spinning wheel assembly spins on the workpiece within a small range.

[0008] Preferably, the spinning wheel is a parabolic cone with the large end cone surface close to the workpiece, thereby forming an asymmetrical tangential pressure component and forming an arc-shaped pressure towards the rear and outer side of the workpiece when the seat rotates.

[0009] The beneficial effects of this utility model are as follows:

[0010] Compared with the existing technology, this utility model adopts multi-axis compound motion, which not only improves the spinning accuracy but also increases efficiency. The added Z-axis uses a spinning wheel assembly to perform flanging spinning within a small range with the workpiece. The flanging process achieves tilt angle compensation, so that the spinning wheel generates radial pressure components and tangential pressure components to act on the workpiece, which improves the uniformity of the working material flow and ensures that the workpiece flanging speed does not affect the overall spinning operation.

[0015] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are provided solely for the purpose of clearly illustrating the technical solution of the present invention, offering numerous specific details to provide a more thorough understanding. However, those skilled in the art will recognize that the present invention can be implemented without one or more of these details. In these examples, to avoid confusion with the present invention, some technical features known in the art have not been described.

[0016] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. Therefore, these embodiments are merely examples and should not be used to limit the scope of protection of the present invention.

[0017] Additionally, it should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0018] See Figures 1 to 3The high-efficiency flanging mechanism equipped in the spinning machine is specifically configured as follows: A rotary drive device C, operating along the Z-axis, is mounted on the composite motion guide rails of the X-axis and Y-axis of the spinning wheel drive module. A rotary seat assembly B is installed at the actuating end of the rotary drive device C. The rotary seat assembly B includes: an L-shaped base 1, which can be directly fixed to the output end of the drive device C, or indirectly fixed to the output end of the drive device C via a flange coupling 3. Above the L-shaped base 1, at the cantilevered end, there is also an important spinning wheel assembly 2, which includes a spinning wheel bracket 21 and a laterally placed spinning wheel 22.

[0019] In implementation, the drive unit C uses a servo motor, and the rotary seat assembly B replaces the traditional single spinning wheel. This allows the cantilevered end above the L-shaped base 1 of the rotary seat assembly B to spin the workpiece A at close range via the spinning wheel assembly 2. This avoids the technical problem of traditional spinning wheels requiring the entire spinning wheel drive module to extend and retract along the Y-axis and the X-axis to coordinate extension and retraction to achieve a large stroke in order to complete the flanging operation. Therefore, even if the spinning range and flanging tendency are large, the rotary drive unit C can drive the rotary seat assembly B to turn independently, or the Y-axis can be adjusted for extension and retraction simultaneously. The entire flanging process will not be slowed down, resulting in a more efficient and faster flanging operation.

[0020] Furthermore, as an improvement to this utility model, the driving device C is installed at the end of the Y-axis linear slide 4 of the spinning wheel drive module, and the Y-axis linear slide 4 is mounted on the slide rail 5 that makes up the X-axis via the slide block 6.

[0021] A connecting sidewall 41 is symmetrically mounted on both sides below the Y-axis linear slide 4 above the slide block 6. Sidewall sliders 43 are installed on the inward side of the connecting sidewall 41. Y-axis linear slide rails 42 are mounted on both sides of the Y-axis linear slide 4, which has an "I"-shaped cross-section. The Y-axis linear slide rails 42 on both sides are inserted into the sidewall sliders 43 fixed on the connecting sidewall 41 on both sides. A Y-axis servo motor fixed on the slide block 6 is installed inside the Y-axis linear slide 4, which has an "I"-shaped cross-section. The output end of the Y-axis servo motor is fixed below the Y-axis linear slide 4. The movement of the Y-axis linear slide 4 of the spinning wheel drive module in the Y-axis direction is controlled by the extension and retraction of the Y-axis servo motor.

[0022] The X-axis servo motor 7 is fixedly mounted on the machine base. The output end of the X-axis servo motor 7 is fixed to the bottom of the slide 6. The slide 6 can be moved along the X-axis by controlling the X-axis servo motor 7.

[0023] Furthermore, as an improvement to this utility model, the bottom of the L-shaped base 1 is provided with a mounting hole 11 having a positioning notch, and the drive device C drives the base body to rotate by matching the mounting hole 11 with the output shaft; the rotation axis I of the spinning wheel assembly 2 forms an angle compensation with the rotation axis of the L-shaped base 1, and the spinning wheel assembly 2 generates a gradual flanging pressure gradient when radially feeding, thereby achieving an arc-shaped flanging effect when the spinning wheel assembly 2 spins on the workpiece A within a small range.

[0024] In this embodiment, the spinning wheel assembly 2 achieves tilt angle compensation during the spinning wheel rotation and flanging process, so that the spinning wheel generates radial pressure components and tangential pressure components to act on the workpiece, thereby improving the uniformity of the working material flow and ensuring that the workpiece flanging speed does not affect the overall spinning operation.

[0025] Furthermore, as an improvement to this utility model, the spinning wheel 22 is a parabolic cone, with the large end cone surface close to the workpiece A, thereby forming an asymmetrical tangential pressure component corresponding to workpiece A in other parts besides the large end cone surface, and forming an arc-shaped pressure towards the rear and outer side of the workpiece when the seat rotates.

[0026] In this embodiment, the parabolic cone of the spinning wheel 22 can achieve the above-mentioned effect. For workpiece A, a brief contact is sufficient to apply tangential pressure to the workpiece A in a small gap area by the spinning wheel 22 driven by the driving device C, resulting in the workpiece A being flanged. The effect is good and the speed is fast.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
