CN202996583U - Clamp seat of pay-off reel - Google Patents

Abstract

The utility model relates to a pay-off support, in particular to a clamp seat of a pay-off reel for winding a transformer coil. The clamp seat comprises a circular-table-shaped clamp seat main body, wherein the clamp seat main body is axially provided with a screw hole matched with threads of a payoff rack roller, and an annular block piece is arranged at one larger end of the clamp seat main body. With the adoption of the technical scheme, the clamp seat of the pay-off reel is simple in construction and convenient to use, and can prevent the pay-off reel from jump.

Description

A kind of draw drum deck

Technical field

The utility model relates to a kind of wire-unfolding rack, the deck of the draw drum that particularly uses during a kind of transformer coil winding.

Background technology

The transformer capacity of using now is larger, and is also larger on the impact 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 is mainly manifested on the manufacture process control of coil, namely requires the high-voltage coil and low-voltage coil electromagnetic balance, axially turn-to-turn closely, be evenly distributed.Therefore require the coil winding process axially will compress, radially will roll tightly, axially naturally compress.The coil winding process is to be installed on the roller bearing of pay off rack being wound with the finished product enameled wire payoff reel, and iron core is arranged on tensioning apparatus, and tensioning apparatus rotates to be wound around 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.

Although existing pay off rack can satisfy the requirement of coil winding to a certain extent, but in actual use procedure, it still exists following technical problem, because the shaft hole diameter of different draw drums is not of uniform size, and the roller bearing diameter of pay off rack is unified, although draw drum axis hole two ends by fastening nuts to the roller bearing, 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 is to provide 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 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 end that described deck main body is larger is provided with annular catch.

Adopt the draw drum deck of technique scheme to have following advantage: 1, due to the deck main body that only includes 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 end that described deck main body is larger is provided with annular catch, so it is relatively simple for structure; 2, during use, only it need to 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 the process of rotating again, no longer affects workman's coiling.

As preferred version, in order to rotate more easily and fastening deck main body, be provided with a handles on described annular catch.

As preferred version, for the better draw drum that adapts to diameter commonly used, and save to greatest extent cost, the tapering of described deck main body is 1:3.

Fig. 2 is the side-looking structural representation of the utility model embodiment draw drum deck.

Embodiment

Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:

As depicted in figs. 1 and 2, the utility model provides a kind of 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 end that deck main body 1 is larger is provided with annular catch 4, be provided with a handles 5 on annular catch 4, the tapering of deck main body 1 is 1:3.

Above-described is only 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 affect effect and practical applicability that the utility model is implemented.
