A winding machine platform is usually provided on the outer periphery of the bottom of a vertical winding machine, and operators stand on the winding machine platform for operations (such as loading and unloading, maintenance, etc.).

[0003] The winding machine is installed in a receiving hole at the center of the platform, and the transformer coil is installed on the winding machine; since the diameter range of the transformer coil workpiece varies greatly, for example, the minimum diameter of the coil of a 20-ton vertical winding machine is 1 m, and the maximum diameter reaches 3 m. When the diameter of the workpiece is small, the operator stands too far away on the platform to reach the workpiece for operation. Therefore, the traditional winding machine platform is provided with 4 movable covers, arranged in a cross shape. This group of covers can move back and forth to form a nearly quadrilateral hole in the center. According to the size of the workpiece diameter, the size of the quadrilateral hole is adjusted, and the operator can stand on it to reach the coil for work.

[0004] The inner diameter of the traditional winding machine platform cannot be adapted to fit the workpiece, and it is easy to form a large gap at the sharp corners of the quadrilateral hole. This gap will bring potential safety hazards (such as the operator is prone to stepping into the void, and the operating tools are prone to falling in, etc.). Summary of the Invention

The inner ends of the plurality of blades 1 are sequentially press-connected to form an annular or quasi-annular shape to constitute the inner diameter of the blade group. The annular shape is, for example, a circular ring shape, a polygon shape and other closed-loop structures, and the quasi-annular shape is, for example, a C-shaped structure. The blade 1 can rotate around the rotation center 10, so as to change the position of the inner end of the blade 1, so as to realize the opening and closing of the blade group, that is, to adjust 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 workpieces to be processed with different sizes.

[0022] Referring to Figure 1 , Figures 9 - 13 , it further includes a support frame 2 and a driving ring 3; a receiving hole for receiving the workpiece to be processed is provided in the middle of the support frame 2; the driving ring 3 is arranged in the middle of the support frame 2 and can rotate; a driving protrusion 17 is provided on the bottom surface of each blade 1; the driving ring 3 is provided with a plurality of arc-shaped chutes 31, and the driving protrusion 17 is placed in the arc-shaped chutes 31 and can slide along the length direction of the arc-shaped chutes 31. The driving protrusion 17 is a first bearing, which is installed on the bottom surface of the blade 1 through an insertion shaft. The insertion shaft is vertically and fixedly connected to the blade 1 (for example, through threaded connection). The first bearing is placed in the arc-shaped chute 31 to reduce the sliding friction, so as to improve the smoothness of the driving ring 3 driving the blade 1 to rotate.

[0023] Referring to Figure 11 and Figure 13 , the arc-shaped chute 31 is inclined, one end of the arc-shaped chute 31 is located inside the driving ring 3, and the other end is located outside the driving ring 3. When the driving ring 3 rotates, the arc-shaped chute 31 can push the driving protrusion 17 to move along the radial direction of the blade group, so as to realize the rotation of the blade 1.

[0024] Referring to Figure 1 , Figure 11 and Figure 13, when the driving ring 3 rotates, it can drive the blade 1 to rotate to change the inner diameter of the blade group, so as to adapt to enclose, cover or fit the outer wall of workpieces with different outer diameters (during the winding process, the diameter of the workpiece gradually increases), that is, the inner diameter size of the blade group is adjustable and can adapt to and fit the outer wall of the workpiece.

[0025] Refer to Figure 9 And Figure 10 , the driving ring 3 is located at the outer edge position of the receiving hole, and the driving ring 3 is concentrically arranged with the receiving hole. When the workpiece is placed in the receiving hole, the driving ring 3 is sleeved on the outer periphery of the workpiece, so as to facilitate driving the driving ring 3 to rotate.

The maximum inner diameter 100 can adapt to the maximum outer diameter of the workpiece to be accommodated. The first edge 11 is in an arc shape, 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, and several circumferentially arrayed first edges 11 can form the inner diameter of the blade group. The third edge 13 is in a straight shape.

[0028] Refer to Figures 2 - 4 , the first edge 11 includes a first arc 111 and a second arc 112 whose ends are connected and tangent to each other. The angle of the first arc 111 is 360 / N degrees, and the angle of the second arc 112 is 10-25 degrees; that is, R1 is 360 / N degrees and R2 is 10-25 degrees.

[0029] Refer to Figure 4 , when the blade 1 rotates to make the third edge 13 coincide with the side of the regular polygon, the ends of the first arc 111 and the second arc 112 both coincide with the perpendicular bisector 101 of the reference center, and the first arc 111 and the second arc 112 are respectively arranged on the left and right sides of the reference center. The perpendicular bisector 101 or its extension line can pass through the center of the inner diameter of the blade group, that is, the center of the circumscribed circle.

[0030] Refer to Figure 3 、 Figure 4 And Figure 5, a second edge 12 is further provided at the inner end of the blade 1. 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. The second edge 12 is arranged along the radial direction of the circumcircle of the regular polygon. The included angle between adjacent second edges 12 is 360 / N degrees, that is, R3 is 360 / N degrees.

[0031] Refer to Figure 3 and Figure 6 , the fourth edge 14 includes a first straight edge 131 and a second straight edge 132 which are end-connected and collinear. The end of the first straight edge 131 away from the second straight edge 132 is connected to the fourth edge 14. The included angle between the fourth edge 14 and the first straight edge 131 is 360 - (360 / N) degrees, that is, R4 is 360 - (360 / N).

[0032] Refer to Figure 6 , when the blade 1 rotates to make the third edge 13 coincide with the side of the regular polygon, the ends of the first straight edge 131 and the second straight edge 132 both coincide with the perpendicular bisector 101 of the reference center, and the first straight edge 131 and the second straight edge 132 are respectively arranged on the left and right sides of the reference center.

A sixth edge 16 is further 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.

[0035] Refer to Figure 6 , a first end point 1311 is provided at the end of the first straight edge 131 away from the second straight edge 132, and a second end point 1321 is provided at the end of the second straight edge 132 away from the first straight edge 131. When the blade 1 rotates to make the third edge 13 coincide with the side of the regular polygon, both the first end point 1311 and the second end point 1321 are located between two adjacent rotation centers 10, that is, the third edge 13 is displaced from the rotation center 10.

[0036] Refer to 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 less than the distance between two adjacent rotation centers 10, and the length difference can accommodate the diameter of the second bearing. Refer to Figure 7 , the angle between the straight line where the first end point 1311 and the center of the inner diameter of the blade group and the perpendicular bisector 101 is R5, and the angle between the straight line where the second end point 1321 and the center of the inner diameter of the blade group and the perpendicular bisector 101 is R6, where R5 is 0.28*(360 / N) to 0.34*(360 / N), and R6 is 0.34*(360 / N) to 0.4*(360 / N).

The support platform 2222 is a steel structure with an I-shaped longitudinal section, thus having excellent load-bearing capacity.

[0042] Refer to Figure 16 , it further includes a cover plate 4, the cover plate 4 is crimped on the upper surface of the support platform 2222 and connected (for example, detachably connected by barrel bolts), so that it is convenient for the user to remove the cover plate 4 and clean the inner cavity of the present invention during maintenance. The blade 1 is placed between the cover plate 4 and the driving ring 3, that is, the cover plate 4 is located above the blade group, the blade group is located above the driving ring 3, and the driving ring 3 is located above the inner support assembly 22, then the support platform 2222 can support the cover plate 4 to prevent the cover plate 4 from being crimped on the upper surface of the blade group, thereby improving the rotation smoothness of the blade 1 and reducing the noise generated by friction.

[0060] S15. A line segment is drawn between the target center and the third edge 13 as the sixth edge 16, and one end of the sixth edge 16 is connected to the end of the third edge 13 far from the fourth edge 14, and the other end is tangentially set to the outer contour of the target center.

[0061] S16. 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 are connected to obtain the blade profile; during the process, fillets are made at the connection positions of different edges.

[0062] S17. The blade 1 is manufactured by cutting according to the blade profile.

[0063] S18. Assemblies of the blade 1, the support frame 2, and the drive ring 3 are carried out.

[0064] Steps S1 - S16 are the design methods of the blade profile. This design method enables the sequential association of the operation requirements of the workpiece to be processed (i.e., the maximum diameter of the workpiece to be processed) with the rotation center 10 of the blade 1 and the dimensions of each edge, so that standardized design (such as realized manually or by using software) can be achieved, thereby improving the design efficiency and the overall production capacity.

[0065] Refer to Figure 17, the outer edge of the rotation center 10 is the upward view projection of the outer edge of the second bearing. The outer edge of the rotation center 10 includes an inscribed edge 10a and a circumscribed edge 10b that are spliced together to form a complete circle. The inscribed edge 10a, the circumscribed edge 10b, and the fifth edge 15 intersect at the same position, and the inscribed edge 10a, the circumscribed edge 10b, and the sixth edge 16 intersect at the same position. In step S16, the circumscribed edge 10b is used as part of the blade profile.

[0066] When N = 8, that is, eight rotation centers 10 are arranged in a regular octagon shape, 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 is, R6 is 12.6 - 15.3 degrees (usually 13 degrees), R7 is 15.3 - 18 degrees (usually 18 degrees). Thus, the standardized design and manufacture of the blade profile can be realized, the production efficiency can be improved, the mistakes in structure and dimension design can be reduced, the product quality can be improved, and the rapid batch manufacturing of winding machine platforms with similar structures and different specifications can be achieved; eight support plates 211 are paired in twos and arranged in an aggregated shape; the outer frame 21 has a square structure, and the support plate group is arranged in the middle of the side of the outer frame 21, so that accommodation 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 accommodation gaps to stably support the cover plate 4.

[0067] 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 - 5.4 meters (usually 4.8 meters); the rotation center 10 uses the second bearing as a standard part, and the outer edge dimension data of the rotation center 10 is selectable. Therefore, after selecting the rotation center 10, 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 can be deduced using the data R0 and the aforementioned angle data.

[0068] Refer to Figure 18 , after the vertical winding machine platform is assembled, when the user rotates the blade 1 inward until the fourth edge 14 is located inside the driving ring 3 and the third edge 13 overlaps the inner edge position of the driving ring 3, the size data R1min of the minimum inner diameter 1000 can be obtained (using fillets with different radii will result in different R1min data because by selectively setting the radius of the fillet, the required R1min can be obtained). The maximum inner diameter 100 and the minimum inner diameter 1000 are concentrically arranged.

[0069] In the present invention, the blade group can contract and expand to fit workpieces of different sizes (transformer coils), thereby avoiding too large a gap between the workpiece and the present invention and improving the safety of production operations. The blade group includes several blades 1 arranged in a circumferential array, and the blades 1 are synchronously rotated by means of a driving ring 3, avoiding problems such as increased structural complexity caused by driving each one individually. The present invention has a simple structure, reliable functions, and strong load-bearing capacity, and has broad market prospects.
