The utility model is simple in structure, and is easily manufactured, functional; The installation electromagnetic wire is convenient and swift, and effective tensile force can be provided, and tensile force can be regulated within the specific limits; Use this tightening device can effectively control product size and product design; Alleviate labor strength, enhance productivity, increase product yield.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

As shown in Figure 1; The bracing frame 1 of this tightening device can be whole device secure support is provided, and can fix on the ground, and bearing seat 3 is fixed on the end face of bracing frame 1; Main shaft 2 levels are passed the antifriction-bearing box that is positioned at bearing seat 3, and fixedly addendum cone 7 is through being bolted to the midway location of main shaft 2.Driving lever 4 one ends and fixing addendum cone 7 weld togethers; Thereby realize that driving lever 4 and main shaft 2 rotate synchronously; Have the oblong notch on the driving lever 4, the rear end level of backing pin 8 is passed notch and is connected on the driving lever 4 through nut, the adjusting position thereby backing pin 8 can slide in notch; Backing pin 8 can be through in the drum knock hole, thereby realize that polytype drum rotates through lever body and main shaft 2 synchronously.Front end at main shaft is provided with movable addendum cone 6, can with firm being fixed on the main shaft 2 of drum in multiple installation aperture, avoid producing the play phenomenon through the position of adjusting activity addendum cone 6 on main shaft 2.When the less drum of width is installed, can regulate at the front end socket axle head sleeve pipe 13 of main shaft 2, to save time; Nut 12 main shaft 2 that is threaded; Can be used for locking drum, prevent that drum from producing longitudinal travel along main shaft 2, wherein axle head sleeve pipe 13 is between movable addendum cone 6 and nut 12.

The center of friction disc 5 can be rotated with main shaft 2 through being bolted to the rear end of main shaft 2 synchronously, and the web of friction disc 5 is between front plate 9 and rear plate 14.Fixed bearing 15 on the rear wall of bracing frame 1; The lower end of front plate 9 and rear plate 14 is separately fixed on the bearing 15; Their installed inside is by friction lining heat-resisting, that the abrasion resistant elastomeric material is made; The front end of screw rod 16 is fixed on the front plate 9, and the rear end level of screw rod 16 is passed rear plate 14 and the pre-load nut 11 that is threaded, and the compression spring 10 that is enclosed within on the screw rod 16 is connected between rear plate 14 and the pre-load nut 11.Through turning pre-load nut 11, the amount of compression that can regulate compression spring 10, thereby the clamped condition of adjusting front plate 9 and rear plate 14; The friction force that friction disc is contacted with friction lining and produce when relative motion is arranged is adjusted, and in the coiling process, pre-load nut 11 is in the pretension state; Make compression spring 10 that certain amount of compression arranged, when main shaft 2 rotated, friction disc mechanism can make main shaft 2 be in braking mode; The tensile force when thereby coiling is provided; And when suspending coiling, brake function can be provided, and prevent that drum from freely rotating, cause back work to increase; And can be according to electromagnetic wire type and coiling needs manual regulation tensile force, achieve effective control product design.

When the coiling transformer coil, place the spooling equipment rear side to this device, and mediate, bracing frame 1 fixes on the ground.Before drum is installed, at first take off nut 12, axle head sleeve pipe 13 and movable addendum cone 6, then drum is penetrated main shaft 2 at main shaft 2 front ends; Regulate the position of backing pin 8 on driving lever 4, backing pin 8 is through in the knock hole of drum end face, and locking backing pin 8; Installation activity addendum cone 6, axle head sleeve pipe 13 and nut 12 in order then; And fastening nut 12 makes firm being fixed on the main shaft 2 of drum, regulates pre-load nut 11 according to the actual needs of electromagnetic wire type and coiling, thereby regulates tensile force; Make electromagnetic wire be in effective tensioning state, thereby improve the quality of products.
