Abstract
The utility model relates to a pay-off support, in particular to a clamping seat of a pay-off spool used at transformer coil winding time. The clamping seat comprises a clamping seat main body in a shape of a circular truncated cone and is characterized in that a screw hole matched with threads of a rolling shaft of the pay-off support is arranged in the axial direction of the clamping seat main body, and strip-shaped protrusions on the same plane with the axis are evenly distributed on the side surface of the clamping seat main body. The clamping seat of the pay-off spool is simple in structure, convenient to use, and capable of preventing the pay-off spool from jumping.
Description
Technical field
The utility model relates to a kind of wire-unfolding rack, particularly the deck of the draw drum that uses during a kind of transformer coil winding.
Background technology
The transformer capacity of using is more big now, and is also more big to the influence of electrical network, requires its fail safe also more and more higher.The workmanship performance of transformer not only requires electric property reliable, and mechanical stability, anti-short circuit capability also should be more reliable.Stability mainly shows and namely requires the high-voltage coil and low-voltage coil electromagnetic balance on the manufacture process control of coil, axially turn-to-turn closely, be evenly distributed.Therefore require the coil winding process axially will compress, radially will roll tightly, axially compress naturally.The coil winding process is to be installed on the roller bearing of pay off rack being wound with finished product enamelled wire draw drum, and iron core is installed on the tensioning apparatus, and tensioning apparatus rotates to twine enamelled wire, and the hand-held enamelled wire of workman is adjusted winding position to guarantee that coil axes is tight to turn-to-turn.
Though existing pay off rack can satisfy the requirement of coil winding to a certain extent, but it still exists following technical problem in the actual use, because different its axis holes of draw drum is not of uniform size, and the roller bearing diameter of pay off rack is unified, though draw drum axis hole two ends have been fastened on the roller bearing by nut, but when the axis hole of draw drum during greater than the roller bearing diameter, draw drum will be beated around roller bearing under the tearing of enamelled wire, cause the workman to be difficult to coiling enamelled wire accurately, therefore be badly in need of and carry out perfect to the fixture of draw drum.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple structure, easy to use and can prevent the deck that draw drum is beated.
In order to solve the problems of the technologies described above, the utility model provides a kind of truncated cone-shaped draw drum deck, include the deck main body of truncated cone-shaped, described deck body shaft is to being provided with a screw that matches with pay off rack roller bearing screw thread, and the side surface of described deck main body evenly is provided with and the isoplanar strip projected parts of axis.
Adopt the truncated cone-shaped draw drum deck of technique scheme to have following advantage: 1, owing to only include the deck main body of truncated cone-shaped, described deck body shaft is to being provided with a screw that matches with pay off rack roller bearing screw thread, the side surface of described deck main body evenly is provided with and the isoplanar strip projected parts of axis, so it is relatively simple for structure; 2, during use, only it need be replaced nut, a less end is aimed at the axis hole of draw drum, tightens to get final product, and is very easy to use; 3, because the deck main body of truncated cone-shaped has certain tapering, it can snap in draw drum axis hole and coaxial with axis hole, so draw drum can not beat in rotating process again, no longer influences workman's coiling.
As preferred version, in order to rotate more easily and fastening deck main body, the bottom of described deck main body is provided with a handle.
As preferred version, for the better draw drum that adapts to diameter commonly used, and save cost to greatest extent, the tapering of described deck main body is 1:3.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment truncated cone-shaped draw drum deck.
Fig. 2 is the structure side view of the utility model embodiment truncated cone-shaped draw drum deck.
Embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, 2, the utility model provides a kind of truncated cone-shaped draw drum deck, include the deck main body 1 of truncated cone-shaped, deck main body 1 axially be provided with a screw 2 that matches with screw thread on the pay off rack roller bearing, the side surface of deck main body 1 evenly is provided with and the isoplanar strip projected parts 3 of axis, the bottom of deck main body 1 is provided with a handle 4, and the tapering of deck main body 1 is 1:3.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
