Description

Technical Field

[0001] The present invention relates to the technical field of winding machine tooling, and in particular to a vertical winding machine platform and a design and manufacturing method thereof. Background Art

[0002] A winding machine is a device used to wind transformer coils. Vertical winding machines typically have a platform on the bottom periphery, where users stand to perform operations (such as loading and unloading materials, and performing maintenance).

[0003] The winding machine is installed in the receiving hole at the center of the platform, and the transformer coil is mounted on the winding machine. Due to the wide range of diameters of transformer coil workpieces, for example, the minimum diameter of a 20-ton vertical winding machine coil is 1m, and the maximum diameter is 3m. When the workpiece diameter is small, the user standing on the platform is too far away to reach the workpiece for operation. Therefore, the traditional winding machine platform is equipped with four movable covers arranged in a cross shape. This set of covers can move back and forth, forming a nearly quadrilateral hole in the center. The size of the quadrilateral hole can be adjusted according to the diameter of the workpiece, allowing the user to stand on top and reach the coil for operation.

[0004] The inner diameter of the traditional winding machine platform cannot adapt to fit the workpiece, and it is easy to form a large gap at the sharp corners of the quadrilateral hole.

[0065] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0066] Reference Figures 1 and 2 , this embodiment provides a vertical winding machine platform, including a blade group; the blade group includes a plurality of blades 1 arranged in a circular array, the outer end of each of the blades 1 is respectively provided with a rotation center 10, and the inner ends of the plurality of blades 1 are sequentially crimped into a ring or a quasi-ring to form the inner diameter of the blade group. The ring is, for example, a closed-loop structure such as a circular ring or a polygon, and the quasi-ring is, for example, a C-shaped structure. The blade 1 can rotate around the rotation center 10, thereby changing the position of the inner end of the blade 1 to realize the opening and closing of the blade group, that is, adjusting the size of the inner diameter of the blade group, so that the inner diameter of the blade group can fit the outer diameter of the workpiece of different sizes.

[0067] Reference Figure 1 、 Figures 9 to 13 , further comprising a support frame 2 and a drive ring 3; a receiving hole for accommodating a workpiece is provided in the middle of the support frame 2; the drive ring 3 is rotatably disposed in the middle of the support frame 2; a drive protrusion 17 is provided on the bottom surface of each blade 1; and the drive ring 3 is provided with a plurality of arcuate slots 31, within which the drive protrusions 17 are positioned and capable of sliding along the length of the arcuate slots 31. The drive protrusions 17 serve as first bearings, mounted on the bottom surface of the blade 1 via an insert shaft, which is vertically fixedly connected to the blade 1 (e.g., by a threaded connection). The first bearings are positioned within the arcuate slots 31 to reduce sliding friction and improve the smoothness of the blade 1's rotation driven by the drive ring 3. A winding machine is mounted at the bottom of the receiving hole and fixedly connected to the support frame 2 (e.g., by bolts). The workpiece is mounted on the winding machine, with the lower and middle portions of the workpiece positioned at the top of the receiving hole, allowing the blade assembly to fit snugly around the outer wall of the workpiece.

[0068] Reference Figure 11 and Figure 13 The arc-shaped slide groove 31 is set at an angle, with one end of the arc-shaped slide groove 31 located on the inner side of the drive ring 3 and the other end located on the outer side of the drive ring 3. When the drive ring 3 rotates, the arc-shaped slide groove 31 can push the drive protrusion 17 to move along the radial direction of the blade group, thereby realizing the rotation of the blade 1.

[0069] Reference Figure 1 、 Figure 11 and Figure 13 When the driving ring 3 rotates, it can drive the blades 1 to rotate to change the size of the inner diameter of the blade group so as to adapt to enclosing, covering or fitting the outer wall of the workpiece with different outer diameters (during the winding process, the diameter of the workpiece gradually increases), that is, the inner diameter of the blade group is adjustable and can adapt to fit the outer wall of the workpiece.

[0070] Reference Figure 9 and Figure 10 The drive ring 3 is located at the outer edge of the receiving hole and is concentric with the receiving hole. When the workpiece is placed in the receiving hole, the drive ring 3 is sleeved on the outer circumference of the workpiece, thereby facilitating the drive ring 3 to rotate.

[0071] Reference Figure 2 , several of the rotation centers 10 are arranged in an outwardly convex regular polygonal shape, thereby realizing an equidistant and equi-angled circular array of blades 1, and the number of sides of the regular polygon is N, which is a positive integer ≥6.

[0072] Reference Figure 3 and Figure 4The inner edge position of the blade 1 is provided with a first edge 11, and the outer edge position is provided with a third edge 13; when the blade 1 rotates until the third edge 13 coincides with the side of the regular polygon, several first edges 11 constitute the maximum inner diameter 100 of the blade group. The maximum inner diameter 100 can accommodate the maximum outer diameter of the workpiece. The first edge 11 is an arc-shaped structure, and the opening direction of the first edge 11 points to the center of the inner diameter of the blade group. The first edge 11 is used to directly fit the outer wall of the winding machine. Several first edges 11 in a circular array can constitute the inner diameter of the blade group. The third edge 13 is a straight-sided structure.

[0073] Reference Figures 2 to 4 The first edge 11 includes a first arc edge 111 and a second arc edge 112 that are connected to each other at the ends and arranged tangently. The angle of the first arc edge 111 is 360 / N degrees, and the angle of the second arc edge 112 is 10 to 25 degrees; that is, R1 is 360 / N degrees and R2 is 10 to 25 degrees.

[0074] Reference Figure 4 When blade 1 rotates until third edge 13 coincides with the side of the regular polygon, the ends of first arc edge 111 and second arc edge 112 both coincide with perpendicular bisector 101 of the reference center, and first arc edge 111 and second arc edge 112 are located to the left and right of the reference center. Perpendicular bisector 101 or its extension can pass through the center of the inner diameter of the blade assembly, i.e., the circumscribed circle.

[0075] Reference Figure 3 、 Figure 4 and Figure 5 The inner end of the blade 1 is also provided with a second edge 12, the end of the second edge 12 is connected to the end of the first arc edge 111 away from the second arc edge 112, and the second edge 12 is arranged along the radial direction of the circumscribed circle of the regular polygon; the angle between adjacent second edges 12 is 360 / N degrees, that is, R3 is 360 / N degrees.

[0076] Reference Figure 3 and Figure 6 The fourth edge 14 includes a first straight edge 131 and a second straight edge 132 that are connected at their ends and arranged collinearly. The end of the first straight edge 131 away from the second straight edge 132 is connected to the fourth edge 14. The angle between the fourth edge 14 and the first straight edge 131 is 360-(360 / N) degrees, that is, R4 is 360-(360 / N).

[0077] Reference Figure 6 When the blade 1 rotates until the third edge 13 coincides with the side of the regular polygon, the end of the first straight side 131 and the end of the second straight side 132 both coincide with the perpendicular bisector 101 of the reference center, and the first straight side 131 and the second straight side 132 are respectively arranged on the left and right sides of the reference center.

[0078] Reference Figure 3 、 Figure 4 and Figure 6 The two ends of the second edge 12 are connected to the first arc edge 111 and the first straight edge 131 respectively.

[0079] Reference Figure 3 、 Figure 4 and Figure 6 A fifth edge 15 is also provided at the inner edge position of the blade 1, one end of the fifth edge 15 is connected to the end of the second arc edge 112, and the other end is tangent to the rotation center 10; a sixth edge 16 is also provided at the outer edge position of the blade 1, one end of the sixth edge 16 is connected to the end of the second straight edge 132, and the other end is tangent to the rotation center 10.

[0080] Reference Figure 6 The first straight side 131 is provided with a first endpoint 1311 at the end away from the second straight side 132, and the second straight side 132 is provided with a second endpoint 1321 at the end away from the first straight side 131; when the blade 1 rotates until the third edge 13 coincides with the side of the regular polygon, the first endpoint 1311 and the second endpoint 1321 are both located between two adjacent rotation centers 10, that is, the third edge 13 and the rotation center 10 give way.

[0081] Reference Figure 6 Since the rotation center 10 uses a second bearing, and the second bearing has a certain diameter, the length of the third edge 13 needs to be smaller than the distance between two adjacent rotation centers 10, and the length difference can accommodate the diameter of the second bearing. Figure 7 The angle between the first endpoint 1311 and the straight line where the inner diameter center of the blade group is located and the perpendicular bisector 101 is R5, and the angle between the second endpoint 1321 and the straight line where the inner diameter center of the blade group is located and the perpendicular bisector 101 is R6, where R5 is 0.28*(360 / N)~0.34*(360 / N), and R6 is 0.34*(360 / N)~0.4*(360 / N).

[0082] Reference Figure 8 、 Figure 9 The support frame 2 includes an outer frame 21 and an inner support assembly 22 installed in the outer frame 21. The inner support assembly 22 includes an inner frame 221 and support rods 222. The inner frame 221 is arranged at the center of the outer frame 21. A plurality of support rods 222 are provided and arranged in a divergent shape between the inner frame 221 and the outer frame 21. One end of the support rod 222 is fixedly connected to the inner frame 221 (for example, by welding or bolting), and the other end is fixedly connected to the outer frame 21 (for example, by welding or bolting).

[0083] Reference Figure 8 and Figure 9 The outer frame 21 has a plurality of support plate groups on its inner wall. Each support plate group includes two adjacent support plates 211 in a pair. The support plates 211 are positioned at the same height. The support plates 211 are pressed against the inner support assembly 22. Accordingly, N is an even number.

[0084] Reference Figure 8 and Figure 9 The bottom surface of the support plate 211 is pressed against the upper surface of the support rod 222 and fixedly connected (for example, fixedly connected by bolts or fixedly connected by welding), and the inner edge of the support plate 211 is attached to the inner wall of the outer frame 21 and fixedly connected (for example, fixedly connected by bolts or fixedly connected by welding).

[0085] The rotation center 10 is a second bearing installed on the bottom surface of the blade 1 through a rotating shaft. The second bearing is vertically and fixedly installed on the upper surface of the support plate 211 (for example, fixedly installed by bolts and a bearing sleeve, that is, the outer ring of the second bearing is fixedly connected to the bearing sleeve by bolts, and the shaft sleeve is fixedly connected to the support plate 211 by bolts). The rotating shaft is longitudinally inserted into the inner ring of the second bearing, and the top end of the rotating shaft is vertically connected to the blade 1 (for example, fixedly connected by bolts or inserted through a hole shaft), so that the support plate 211 supports the rotation center 10 and the blade 1 and ensures the smoothness of the rotation of the blade 1.

[0086] Reference Figure 15 A gap is provided between adjacent support plate groups to accommodate support platforms 2222. The support platforms 2222 are fixedly connected to the inner support assembly 22. The bottom end of the support platforms 2222 is fixedly connected to the top surface of the support rod 222 (e.g., by welding or bolts). The support platforms 2222 are steel structures with an I-shaped longitudinal cross-section, providing excellent load-bearing capacity.

[0087] Reference Figure 16 , further comprising a cover plate 4, which is press-fitted to and connected to the upper surface of the support platform 2222 (e.g., by a removable connection using a barrel bolt), thereby facilitating removal of the cover plate 4 and cleaning of the inner cavity of the present invention during maintenance. The blades 1 are positioned between the cover plate 4 and the drive ring 3, i.e., the cover plate 4 is positioned above the blade assembly, the blade assembly is positioned above the drive ring 3, and the drive ring 3 is positioned above the inner support assembly 22. The support platform 2222 is capable of supporting the cover plate 4, preventing the cover plate 4 from being pressed against the upper surface of the blade assembly, thereby improving the smoothness of the blade 1's rotation and reducing noise generated by friction.

[0088] Reference Figure 9 、 Figure 10 and Figure 11The top surface of the inner frame 221 is mounted with several curved guide rails 2211. These guide rails 2211 are arranged intermittently in a circular pattern and support the inner edge of the drive ring 3. Rollers 2212 are installed in the gaps between adjacent guide rails 2211. These rollers 2212 are mounted on the top surface of the inner frame 221 via bearings. An annular groove is defined on the circumference of the rollers 2212, and the inner edge of the drive ring 3 engages within the groove. Several rollers 2212 are arranged in a circular pattern. The rollers 2212 are freely rotatable, providing positional support for the inner edge of the drive ring 3 and reducing rotational friction. The blade 1 is press-fitted to the top surface of the guide rails 2211.

[0089] Reference Figure 12 A support wheel 2221 is provided on the side wall of the support rod 222, and the drive ring 3 is pressed on the support wheel 2221. The drive ring 3 can rotate freely, thereby achieving support and limiting the bottom surface of the drive ring 3 and reducing the rotation friction of the drive ring 3.

[0090] Reference Figure 14 , the outer edge of the drive ring 3 is provided with a transmission tooth structure 32; Figure 9 and Figure 10 A drive motor is mounted within the inner support assembly 22. A drive gear is mounted on the output shaft of the drive motor. The drive gear meshes with the transmission tooth structure 32. The drive motor drives the drive ring 3 to rotate via the drive gear, further controlling the opening and closing of the blade assembly. The drive motor is directly or indirectly fixedly connected to the support rod 222. A direct connection is achieved by bolting the housing of the drive motor to the support rod 222. An indirect connection is achieved by bolting the housing of the drive motor to the connecting plate (e.g., via bolts), which in turn is fixedly connected to the support rod 222 (e.g., via bolts).

[0105] S14. Draw a line segment between the target center and the first edge 11 as the fifth edge 15, with one end of the fifth edge 15 connected to the end of the second arc edge 112 away from the first arc edge 111, and the other end is tangent to the outer contour of the target center.

[0106] S15. Draw a line segment between the target center and the third edge 13 as a sixth edge 16, with one end of the sixth edge 16 connected to the end of the third edge 13 away from the fourth edge 14, and the other end being tangent to the outer contour of the target center.

[0107] S16, connecting the first edge 11, the second edge 12, the fourth edge 14, the third edge 13, the sixth edge 16, the circumscribed edge 10b of the target center and the fifth edge 15 to obtain a blade profile; in the process, the connection positions of different edges are rounded.

[0108] S17, cutting and manufacturing the blade 1 according to the blade outline.

[0109] S18, assembling the blade 1, the support frame 2 and the drive ring 3.

[0110] Steps S1 to S16 are a method for designing the blade profile. This method sequentially associates the operational requirements of the workpiece (i.e., the maximum diameter of the workpiece) with the dimensions of the rotation center 10 and each edge of the blade 1, thereby enabling standardized design (e.g., achieved manually or using software), thereby improving design efficiency and overall production capacity.

[0111] Reference Figure 17 The outer edge of rotation center 10 is the bottom projection of the outer edge of the second bearing. The outer edge of rotation center 10 includes an inner edge 10a and an outer edge 10b, which are joined together to form a full circle. Inner edge 10a, outer edge 10b, and fifth edge 15 intersect at the same location. Inner edge 10a, outer edge 10b, and sixth edge 16 intersect at the same location. In step S16, outer edge 10b is considered part of the blade profile.

[0112] When N=8, that is, the eight rotation centers 10 are arranged in a regular octagonal shape, the eight blades 1 are arranged in a circular array, and R1 is 45 degrees, R2 is 10-25 degrees (usually 20 degrees), R3 is 45 degrees, R4 is 135 degrees, R5, R6 is 12.6-15.3 degrees (usually 13 degrees), and R7 is 15.3-18 degrees (usually 18 degrees), thereby realizing standardized design and manufacturing of blade profiles, improving production efficiency, reducing errors in structural and dimensional design, improving product quality, and enabling rapid batch manufacturing of winding machine platforms with similar structures and different specifications; the eight support plates 211 are paired and arranged in a clustered shape; the outer frame 21 is a positive direction structure, and the support plate group is arranged in the middle of the edge of the outer frame 21, so that accommodating gaps for accommodating the support platforms 2222 are respectively formed at the four sharp corners of the outer frame 21, and the four support platforms 2222 are respectively arranged in the accommodating gaps and stably support the cover plate 4.

[0113] When the maximum diameter R of the workpiece is 3 meters, the maximum inner diameter 100R1max of the blade group is 3 meters, then the diameter R0 of the circumscribed circle of the regular polygon is 4.2 to 5.4 meters (usually 4.8 meters); the rotation center 10 uses the second bearing as a standard part, then the outer edge size data of the rotation center 10 is optional, so after selecting the rotation center 10, the data R0 and the aforementioned angle data can be used to deduce the length data of the first edge 11, the second edge 12, the fourth edge 14, the third edge 13, and the sixth edge 16.

[0114] Reference Figure 18 After the vertical winding machine platform is assembled, the operator rotates blade 1 inward until fourth edge 14 is located inside drive ring 3 and third edge 13 overlaps the inner edge of drive ring 3. This results in the minimum inner diameter 1000 dimensional data R1min. (Using different fillet radii will result in different R1min data, but the desired R1min can be achieved by selectively setting the fillet radius.) The maximum inner diameter 100 and the minimum inner diameter 1000 are set concentrically.

[0115] The blade assembly of the present invention can contract and expand to fit workpieces (transformer coils) of varying sizes, thereby avoiding excessive gaps between the workpiece and the present invention and improving production safety. The blade assembly comprises a plurality of blades 1 arranged in a circular array. The blades 1 rotate synchronously with a drive ring 3, avoiding the increased structural complexity associated with individual drive. This invention boasts a simple structure, reliable functionality, and strong load-bearing capacity, and has broad market prospects.
