Abstract

The invention relates to the winding of a lengthy material and can be used in the manufacture of capacitors. The purpose of the invention is to expand the technological capabilities of the coil holder of the winding device by fixing the coils of various lengths. The holder comprises a spindle 2 with a supporting flange and a holder 4 freely mounted on it. The position of the holder is fixed on the spindle by spring-loaded balls 8, wedged in the conical cavities of the holder. The fastening of the coil is dried by a handle 5 with a support flange 6 connected to the holder by a threaded connection. 2 h. item f-ly, 2 ill.

pressing it toward the flange 3 of the spindle 2. To remove the coil 1, the handle 5 rotates in the opposite direction and shuffles to the left of the coil 1. In this case, its annular stop 7 pushes the spring-loaded balls 8 to the left. The casing 4 is opened and opened freely from the spindle 2 while the balls 8 with the springs 10 are pressed against the conical surfaces of the cavities 9 and reliably hold the holder allows the installation of coils of various lengths.

Invention Formula 1. A coil holder comprising a spindle with a support flange, a yoke freely mounted on the spindle, a cylindrical handle with a flange, connection The invention relates to winding long materials and can be used in winding devices in the production of capacitors. The purpose of the invention is the expansion of technological capabilities by providing the possibility of fixing coils of various lengths. FIG. 1 shows the holder, cut; in fig. 2 shows section A-A in FIG. one. The coil holder 1 of the winding is installed in the grooves 12 of the sleeve 11. The device contains a spindle 2 with a support. Thus, the design of the flange 3. A spindle 4 is freely mounted on the spindle. On the casing 4 a cylindrical handle 5 with a flange 6 is fastened on the holder 4. an annular abutment 7 is made to interact with the balls 8. The balls 8 are placed in a conical cavity 9, made in the holder 4, are spring-loaded Adol spindle springs 10. In the horse ....  cavity 9, the balls are held 20 with a clip and having an annular in 1 hole 11, pressed into the clip 4. support for interaction with the spring-loaded. In the sleeve 11, through grooves 12 are made, the balls placed in the radial width of which is smaller than the diameter of the ball. The holes in the sleeve, installed in the coac-conical cavity, are designed so that they are vertically spline, characterized in that the cone tire is extended to the supporting flange to expand the spindle's technological threads. On the spindle 2, the sleeve is rigidly fixed inside the flats 13 to interact with the shari of the holder, the holder has conical lesions. The support flanges of the handle and the spindle, painted with the apex of the cone, support the cone 14 to the spindle flange, and the radial detachments with the coil. The sleeves of the sleeve are made in the form of through the holder works as follows, with its longitudinal grooves, while a ring- To the end of the stop mounted on the spindle 2, an interaction with the coil-1 ball is supplied with a holder in which we place on the handle flange, a ball-shaped stop 7 of the handle 5 and the springs are placed in the conical cavities of the wallpaper balls 8with the extreme left and we are biased along the spindle, and a position which ensures free handle connected to the cage by moving along the spindle holder. 35 threaded connection. with the mouth of the handle 5 it is jammed 2. The holder according to claim. 1, the fact that the flanges of the handle and the spindle have a centering cone facing one another. 3. The holder according to claim 1, characterized in that in that, on the outer surface of the spindle, flats are made to interact with the balls. clamp 4 on the spindle 2 due to the interaction during rotation of the spring-loaded balls 8 with the surface of the conical cavities 9 and the rods 13. With the subsequent rotation of the handle 5, the latter is moved to the right, the cone 4 centers the coil 1 and the flange 6 reliably presses it to the flange 3 spindle 2. To remove the coil 1, the handle 5 rotates in the opposite direction and shuffles to the left of the coil 1. In this case, its annular support 7 pushes the spring-loaded balls 8 to the left. The casing 4 is wedged and its free removal from the spindle 2; 8 ki springs 10 are pressed against the conical surfaces of the cavities 9 and reliably hold  live in the slots 12 of the sleeve 11. Thus, the proposed holder design allows the installation of coils of various lengths. Invention Formula 1. A coil holder, including a spindle with a support flange, a holder, freely mounted on the spindle, a cylindrical handle with a flange, are connected in the slots 12 of the sleeve 11. Thus, the proposed design ..... with a clip and having an annular stop to interact with spring-loaded balls placed in the radial A-A ftsg.g
