A spinning wheel assembly is installed at the end of the spinning wheel drive module Y. The spinning wheel drive module Y is horizontally positioned above or below the spinning wheel drive module X. The spinning wheel drive module X provides linear running power to the spinning wheel drive module Y in the X-axis direction, and the spinning wheel drive module Y provides linear running power to the spinning wheel assembly in the Y-axis direction. The spinning wheel assembly includes a spinning wheel, which is driven by a motor to provide circumferential rotational running power in a direction perpendicular to the spinning wheel drive module X and / or the spinning wheel drive module Y. The innovative spinning wheel assembly adds a small range of movement in the Z-axis circumferential dimension, compensating for the inefficiency and large deviation of the flanging angle caused by the need for compensation of the spatial curvature of the flanging trajectory through a two-dimensional X and Y plane flanging mode, thus achieving high-speed and high-efficiency operation of the spinning machine.

Description

Technical Field

[0001] This utility model relates to a spinning machine, specifically a high-speed automatic spinning machine. 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 X and Y two-dimensional planar motion modes to compensate for workpiece spinning and flanging, which requires larger movements, making the forward and backward movement process more cumbersome, resulting in low flanging efficiency and easy deviation of the flanging angle, and low overall speed. Summary of the Invention

[0003] The purpose of this invention is to solve the shortcomings of the above-mentioned problems and to provide a high-speed automatic spinning machine that achieves high-speed flipping by using a spinning wheel located at the Y end of the spinning wheel moving module to perform spatial curvature compensation through circumferential rotation with the workpiece within a small distance and range when performing flanging operations close to the workpiece.

[0018] 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.

[0019] 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.

[0020] See Figures 1 to 3 A high-speed automatic spinning machine includes a machine base 1, on which a spinning wheel drive module X and a spinning wheel drive module Y are mounted. A spinning wheel assembly 2 is installed at the end of the spinning wheel drive module Y. The spinning wheel drive module Y is horizontally mounted above or below the spinning wheel drive module X. The spinning wheel drive module X provides linear running power to the spinning wheel drive module Y in the X-axis direction, and the spinning wheel drive module Y provides linear running power to the spinning wheel assembly in the Y-axis direction. The spinning wheel assembly 2 includes a spinning wheel 21, which is provided with circumferential rotational running power in a direction perpendicular to the spinning wheel drive module X and / or the spinning wheel drive module Y by a drive motor 22. The spinning wheel drive modules X and Y are usually perpendicularly intersecting. In this implementation, the spinning wheel drive modules X and Y are not parallel, and X and Y do not necessarily represent perpendicularity.

[0021] The current operating principle of a spinning machine is generally as follows: the combined motion of the spinning wheel moving module X and the spinning wheel moving module Y brings the spinning wheel mounted on the spinning wheel moving module Y closer to the workpiece A on the housing 3. The stroke of the spinning wheel is controlled by the pressure wheel moving module Y, or, depending on the need for flanging workpiece A, by the coordination of the pressure wheel moving module X and the spinning wheel moving module Y. Typically, the spinning wheel moving module X drives the pressure wheel moving module Y to bring the spinning wheel closer to workpiece A. Then, the spinning wheel moving module X and the pressure wheel moving module Y work synchronously and coordinately to move the spinning wheel outwards from workpiece A and towards the housing 3 for spinning. Once the spinning roller moves out of the workpiece A's range, the spinning roller moving module X drives the spinning roller moving module Y to retract. This process is repeated, with the workpiece A as the target, and the stroke is gradually reduced. Therefore, it can be seen that the spinning roller relies entirely on the stroke coordination of the spinning roller moving module X and the spinning roller moving module Y. This results in insufficient freedom of the spinning machine's spinning operation, making it difficult to achieve spatial curvature compensation for the workpiece's flanging trajectory. The spinning roller moving module X and the spinning roller moving module Y have multiple large movements relative to the workpiece A, resulting in low flanging efficiency and a large travel distance, which amplifies the flanging angle and easily leads to flanging angle deviation.

[0022] Therefore, in the implementation of this technical solution, the spinning wheel and components including the drive motor 22 are assembled into a spinning wheel assembly 2 installed at the end of the spinning wheel moving module Y. The spinning wheel 21 is provided with circumferential rotational power by the drive motor 22 in a direction perpendicular to the spinning wheel moving module X and / or the spinning wheel moving module Y. In this way, under the action of the drive motor 22, the spinning wheel 21 can complete the spinning and flanging of the workpiece A within a small space with the help of the spinning wheel moving module Y or the spinning wheel moving module Y and the spinning wheel moving module X. This greatly reduces the return adjustment of the spinning wheel moving module X and the spinning wheel moving module Y, thereby liberating the degree of freedom of the spinning machine's spinning operation. Furthermore, the spatial curvature compensation brought about by the trajectory within a small range improves the flanging efficiency, and the flanging angle can be controlled to make the flanging angle more precise.

[0023] Furthermore, as an improvement to this utility model, the drive motor of the spinning wheel assembly 2 is installed below the spinning wheel moving module Y, and a rotating seat 23 is installed on the output end of the drive motor 22, and the spinning wheel 21 is installed on the rotating seat 23; when the spinning wheel 21 cooperates with the spinning wheel assembly 2 to approach the workpiece A on the spinning machine housing 3 in the Y-axis direction, the drive motor 22 drives the rotating seat 23 to rotate to assist the spinning wheel moving module X or / and the spinning wheel moving module Y in achieving high-speed flanging of the workpiece A.

[0024] In this embodiment, the rotating seat 23 rotates within 180 degrees around the axis of the drive motor 22, thus providing a relatively ample flanging area when workpiece A is flanged.

[0025] Furthermore, as an improvement to this utility model, a rotating seat 23 is also included between the spinning wheel 21 and the drive motor 22. The rotating seat 23 is L-shaped, and the bottom of the L-shape is directly or indirectly fixed to the output end of the drive motor 22 through a flange coupling. The upper end of the L-shape is provided with a limiting installation notch 24. The spinning wheel 21 is mounted on a bracket 25, and the bracket 25 is mounted and fixed on the limiting installation notch 24.

[0026] In this embodiment, the rotating seat 23 shown is L-shaped, and the spinning roller 21 is indirectly placed at the end, so that the workpiece A can directly enter the area above the output shaft of the drive motor 22. When the drive motor 22 controls the rotating seat 23 to rotate, the surface of the spinning roller 21 spins the surface of the workpiece A more closely, thereby easily and simply completing the tilt angle compensation. In this process, due to the close distance, the roller generates radial pressure components and tangential pressure components that act on the workpiece, which can improve the uniformity of the flow of the working material.

[0027] Furthermore, as an improvement to this utility model, the spinning wheel drive module X includes an X-axis servo motor 4 and at least one X-axis guide rail 5; the spinning wheel drive module X includes a linear slide 6 that moves linearly in the X-axis direction, with a screw sleeve 61 and a slider 62 mounted below the linear slide 6, the X-axis servo motor 4 being connected to a drive screw 63 passing through the screw sleeve 61 via an X-axis coupling 41, and the slider 62 being fitted onto the X-axis guide rail.

[0028] In this embodiment, there are two X-axis guide rails 5, mounted on a guide rail base (not shown in the figure). The number of sliders 62 depends on the size of the linear slide block 6. Typically, two sliders are arranged on one X-axis guide rail 5, one in front of the other, at both ends of the width direction of the linear slide block 6. The screw sleeve 61 is fixed below the linear slide block 6. The inner side of the screw sleeve 61 has a screw hole for the drive screw 63 to pass through. When the X-axis servo motor 4 is started, the drive screw 63 rotates. Since the screw sleeve 61 is fixed, the rotation of the drive screw 63 corresponding to the screw hole of the screw sleeve 61 forces the linear slide block 6 to move. Under the limit of the X-axis guide rail 5, the linear slide block 6 realizes the forward and backward movement on the X-axis guide rail 5.

[0029] Furthermore, as an improvement to this utility model, the spinning wheel 21 is a parabolic cone, with the large end cone surface close to the workpiece A, thereby forming an asymmetrical tangential pressure component, and when the motor 22 drives the rotation, it forms an arc-shaped pressure toward the rear and outer side of the workpiece A.

[0030] In this embodiment, the parabolic cone of the spinning wheel 21 can achieve the above-mentioned effect. For workpiece A, a brief contact is sufficient to apply tangential pressure to workpiece A in a small gap area by the spinning wheel 21 driven by the drive motor 22, resulting in the workpiece A being flanged. The effect is good and the speed is fast.

[0031] Furthermore, as an improvement to this utility model, the spinning wheel module Y also includes a linear slide 7 that moves linearly in the Y-axis direction. A Y-axis servo motor 8 is installed on the linear slide 7. Rail walls 71 are erected on both sides above the linear slide 7. Fixed sliders 72 are installed on the corresponding surfaces of the two rail walls 71. Y-axis guide rails 73 are installed on both sides of the linear slide 7 and slide into the fixed sliders 72 corresponding to the rail walls 71 on both sides via the Y-axis guide rails 73.

[0032] In this embodiment, a Y-axis servo motor 8 is connected to a Y-axis drive screw 74 via a coupling, and a flange is also fixed to the coupling. The other side of the flange is fixed to the linear slide 7, and a threaded hole is provided in the center of the flange. At the end of the Y-axis drive screw 74 is a screw bracket 75, and a bearing is installed inside the screw bracket 75. The Y-axis drive screw 74 rotates under the drive of the Y-axis servo motor 8, and the drive screw 74 exerts a force on the flange along the threaded hole. Since the flange is fixed on the linear slide 7, the linear slide 7 is indirectly able to move forward and backward.

[0033] 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.
