Description

A transformer end-coil equal division marking auxiliary device Technical Field

[0001] This invention belongs to the field of transformer manufacturing technology, and in particular relates to an auxiliary device for equally dividing and marking transformer end rings. Background Technology

[0002] The transformer end coil is the insulation between the coil end insulation and the yoke, and it is generally composed of a paper coil and a spacer. The difficulty in the end coil processing during manufacturing lies in the division and marking of the end coil. On the production site, equal division templates are usually used for marking, but the difficulty in the equal division template marking operation lies in determining the center of the end coil. On the production site, the center is often determined by finding the intersection point of the arc on the paper coil according to geometric principles. This operation is obviously quite complicated. There is a need in this field for an auxiliary device that can quickly determine the center of the paper coil and mark the equal division. Summary of the Invention

[0003] This invention provides an auxiliary device for equally dividing and marking transformer end coils to solve the problems mentioned in the background art.

[0004] The technical problem solved by this invention is achieved by the following technical solution:

[0005] A transformer end-coil dividing marking auxiliary device includes a platform, a sliding part, calipers, a drive part, and a support part. The sliding part has six sets of circumferential arrays mounted on the platform. The calipers are mounted on the platform. The drive part is mounted on the bottom of the platform and connected to the sliding part. The platform is mounted on the support part.

[0006] The platform section includes a frustum, cross grooves, lugs, an external hinge hole, and a hook. Six cross grooves are evenly distributed around the circumference of the frustum. Lugs are installed below the cross grooves, with hooks facing inwards at the bottom of the lugs. An external hinge hole is located on the outer surface of the lugs. The sliding section includes a dovetail groove, a cross slider, a threaded hole, a dovetail slider, a clamping screw hole, and a round head. A cross slider is located at the bottom of the dovetail groove, fitting snugly within the groove and sliding within it. The bottom of the cross slider has a threaded hole that connects to the drive unit for transmission. A dovetail slider slides on the dovetail groove, positioned above the frustum. The caliper includes a circular plate, extension rods, a flange, and graduations. Six extension rods extend around the circumference of the circular plate, with flanges at the ends. The entire caliper is fastened to the circular plate via these flanges. The drive unit includes a gear ring, a handle ring, a gear, a screw, and a central cap. The gear ring meshes with the gear, which is fixedly mounted on the screw. The gear drives the screw to rotate. The two ends of the screw are hinged to the central cap and the outer hinge hole, respectively. The rotation of the screw then drives the dovetail groove to move through the threaded hole. The gear ring is hooked onto a latch and can rotate on the latch. The support unit includes six columns and reinforcing rings. The columns are supported at the bottom of the frustum. The positions of the columns and the screw should be staggered. The reinforcing rings connect the six columns into a single unit from the middle. This connection can be achieved by welding or by inserting a joint.

[0007] Furthermore, the dovetail slider has a clamping screw hole, and a screw is used on the clamping screw hole to clamp the dovetail slider onto the dovetail groove.

[0008] Furthermore, the dovetail slider has a rounded head at its front end, which abuts against the edge of the end ring cardboard.

[0009] Furthermore, the circular plate has uniform graduations.

[0010] Furthermore, the inner side of the toothed ring extends past the hook and connects to the handle ring from the bottom. The handle ring is the operating component of the entire drive unit. By holding the handle ring and rotating the toothed ring, the entire device can be driven to move and achieve its function.

[0011] Furthermore, the column has a groove that aligns with the boss at the bottom of the truncated cone, improving the stability of the connection between the column and the platform.

[0012] The beneficial effects of this invention are:

[0013] This invention is used for the equal division marking operation of the paper ring at the transformer end. It has a set of six circumferentially distributed sliding parts that move synchronously to determine the center of the paper ring. Then, calipers covered on a circular platform are used to mark the division points of the paper ring, and the equal division marking operation of the paper ring can be completed conveniently.

[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0019] Referring to Figures 1-3, the transformer end coil equal division marking auxiliary device includes a platform part 10, a sliding part 20, a caliper 30, a drive part 40, and a support part 50. The sliding part 20 has six sets of circumferential arrays mounted on the platform part 10. The caliper 30 is mounted on the platform part 10. The drive part 40 is mounted on the bottom of the platform part 10 and connected to the sliding part 20. The platform part 10 is mounted on the support part 50.

[0020] The platform part 10 includes a frustum 11, a cross groove 12, an ear piece 13, an external hinge hole 14, and a hook 15. Six cross grooves 12 are evenly distributed around the frustum 11. A sliding part 20 is fitted onto the cross groove 12. An ear piece 13 is installed below the cross groove 12. The bottom of the ear piece 13 has a hook 15 facing inward. A driving part 40 is installed on the hook 15. An external hinge hole 14 is provided on the outer side of the ear piece 13. The driving part 40 is hinged to the external hinge hole 14.

[0021] The sliding part 20 includes a dovetail groove 21, a cross slider 22, a threaded hole 23, a dovetail slider 24, a clamping screw hole 25, and a round head 26. The bottom of the dovetail groove 21 has a cross slider 22, which is fitted and installed in the cross groove 12 and slides in the cross groove 12. The bottom of the cross slider 22 has a threaded hole 23, which is connected to the drive part 40 for transmission. The dovetail slider 24 is slidably installed on the dovetail groove 21. The dovetail slider 24 is located above the frustum 11. The dovetail slider 24 has a clamping screw hole 25, and a screw is used on the clamping screw hole 25 to clamp the dovetail slider 24 onto the dovetail groove 21. The front end of the dovetail slider 24 has a round head 26, which abuts against the edge of the end ring cardboard.

[0022] The caliper 30 includes a circular plate 31, extension rods 32, folded edges 33, and graduations 34. Six extension rods 32 extend around the circumference of the circular plate 31. The ends of the extension rods 32 have folded edges 33. The entire caliper 30 is fastened to the frustum 11 by the folded edges 33. Of course, the positions of the extension rods 32 are offset from the positions of the cross grooves 12, that is, the positions of the extension rods 32 and the sliding part 20 are offset. The circular plate 31 has uniform graduations 34. Using the caliper 30 and the graduations on the caliper 30, equally divided graduation lines are drawn on the cardboard along the inner side of the circular plate 31. Finally, the lines are extended along the equally divided graduation lines to achieve the equally divided lines on the end ring of the cardboard.

[0023] The drive unit 40 includes a gear ring 41, a handle ring 42, a gear 43, a screw 44, and a central cover 45. The gear ring 41 meshes with the gear 43, which is fixedly mounted on the screw 44. The gear 43 drives the screw 44 to rotate. The two ends of the screw 44 are respectively hinged to the central cover 45 and the outer hinge hole 14. The rotation of the screw 44 drives the dovetail groove 21 to move through the threaded hole 23. The gear ring 41 is hooked on the hook 15 and can rotate on the hook 15. The inner side of the gear ring 41 passes over the hook 15 and is connected to the handle ring 42 from the bottom. The handle ring 42 is the operating component of the entire drive unit 40. By holding the handle ring 42 and rotating the gear ring 41, the entire device can be driven to move and achieve its function.

[0024] The support part 50 includes six columns 51, grooves 52, and reinforcing rings 53. The columns 51 are supported on the bottom of the frustum 11. Of course, the position of the columns 51 should be staggered from the position of the screw 44. The columns 51 have grooves 52, which are connected to the boss (not visible in the figure) on the bottom of the frustum 11 to improve the stability of the connection between the columns 51 and the platform part 10. The reinforcing rings 53 connect the six columns 51 into a whole from the middle of the columns 51. The connection process can be welding or plug-in structure.

[0025] The working principle of this invention is as follows: Holding the handle ring 42, rotate the gear ring 41. The gear ring 41 drives the gear 43 to rotate and drives the screw 44 to rotate. The screw 44 drives the cross slider 22 and the dovetail groove 21 to move in the cross groove 12 through the threaded hole 23. The dovetail slider 24 is fixed in the dovetail groove 21 in advance and moves together with the dovetail groove 21. The round head 26 at the front end of the dovetail slider 24 gradually approaches and abuts against the outer edge of the end ring paper ring until all the round heads 26 abut against the outer edge of the paper ring, thus completing the centering operation of the paper ring. At this time, the caliper 30 is clamped on the round plate 11 and the paper ring is pressed. Using the scale 34 on the round plate 31, the paper ring is marked with equal division points as needed. Then the paper ring is removed, and the paper ring is divided into equal division lines according to the marked points.
