Detailed Description
Referring to fig. 1-4, the embodiment is a controllable paying-off resistance type paying-off rack for bonding wire drawing, which comprises a base 1, wherein a support 2 is arranged on the base 1, a rotating shaft is arranged at the top end of the support 2, the rotating shaft is rotationally connected with the support 2, a circular turntable is arranged at one end of the rotating shaft, a reel supporting component is arranged at one side of the turntable and is used for supporting a wire reel, a belt pulley A9 is fixedly arranged at the other end of the rotating shaft, a synchronous shaft 14 is arranged at the lower end of the support 2, a magnetic powder clutch 13 and a belt pulley B10 are arranged on the synchronous shaft 14, a synchronous belt 11 is wound between the belt pulley A9 and the belt pulley B10, the synchronous belt 11 is tightly contacted with the belt pulley A9 and the belt pulley B10, and the magnetic powder clutch 13 is used for adjusting the rotation resistance of the belt pulley B10.
Further, be equipped with four kidney-shaped holes 8 on the carousel, four kidney-shaped holes 8 are along circumference equipartition, and the centre line of all kidney-shaped holes 8 aims at the centre of a circle of carousel, reel supporting component is including installing the slide 7 in each kidney-shaped hole 8, fixedly on every slide 7 be equipped with a bracing piece 3, all bracing pieces 3 are parallel to each other and with the carousel perpendicular arrangement, a lead screw 5 is equipped with in the center department of carousel, lead screw 5 one end is connected with the carousel rotation, regulating hand wheel 12 is equipped with to the other end of lead screw 5, two swivel nuts 6 are equipped with at the both ends of lead screw 5, the screw thread of two swivel nuts 6 revolves to opposite, every swivel nut 6 outer wall is equipped with the connecting plate with bracing piece 3 one-to-one, be equipped with connecting rod 4 between connecting plate and the bracing piece 3 that corresponds, connecting rod 4 one end is connected with bracing piece 3 rotation, the other end is connected with the connecting plate rotation.
