Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to an aluminum alloy rod tight winding machine. Background Technology

[0002] After the aluminum rods are produced, they need to be wound into a coil using a take-up machine for easy storage and transportation. For example, in the automatic take-up device for aluminum rods disclosed in Chinese literature (patent number: CN201621193577.X), the take-up roller is placed vertically. After the aluminum rods are taken up, it is not convenient to disassemble the coiled aluminum rods. Moreover, there is no tensioning structure on the take-up roller. After the aluminum rods are wound up, they are tightly attached to the take-up roller, making it even more inconvenient to disassemble them.

[0003] Therefore, we propose an aluminum alloy rod tight winding machine. Utility Model Content

[0004] The purpose of this invention is to provide a tight take-up machine for aluminum alloy rods to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy rod tight take-up machine, comprising a take-up machine base, an AC servo motor, a cylinder, a lifting device, a wire guide, a wire gripping swing arm, and a ball screw. Synchronous pulleys are provided on the left side of the take-up machine base and on the AC servo motor. A fixed plate is provided on the take-up machine base, a fixed flange is provided on the right side of the fixed plate, and a movable plate is provided on the fixed flange. A telescopic spindle is provided in the middle of the take-up machine base, a wire-passing groove is provided at the lower part of the fixed plate, a movable shaft is provided on the left side of the telescopic spindle, a buffer spring is provided on the movable shaft, a tensioning plate is provided on the fixed plate, a movable key is connected to the tensioning plate, and the movable key is provided with a movable key shaft.

[0006] Furthermore, the base of the take-up machine is provided with a timing pulley and a main drive gear shaft, and the main drive gear shaft is provided with an electromagnetic friction plate.

[0007] Furthermore, a gear ring is provided on the upper right side of the fixed disk, an eccentric wheel is provided on the right side of the gear ring, and an eccentric wheel shaft is provided on the top of the eccentric wheel.

[0008] Furthermore, a cavity is provided in the middle of the left end of the telescopic mandrel, and the movable shaft extends into the cavity through the telescopic mandrel. The surface of the part of the movable shaft extending into the cavity is provided with threads, and a nut is provided on the end of the movable shaft extending into the cavity.

[0009] Furthermore, the left side of the take-up machine base and the synchronous pulley on the AC servo motor are connected by a belt.

[0010] Furthermore, the two ends of the movable key are connected to the tensioning plate and the telescopic spindle via movable key shafts.

[0011] Furthermore, the tensioning plates are provided in three sets, with an included angle of 120 degrees between adjacent tensioning plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the cylinder pushes the telescopic mandrel to move to the right through the movable shaft, and the buffer spring buffers the movement of the movable shaft, preventing the movable shaft from directly applying impact force to the telescopic mandrel, thus protecting the telescopic mandrel and extending its service life. After the winding is completed, the cylinder pulls the telescopic mandrel to the left through the movable shaft and connector. The movement of the telescopic mandrel drives the tension plate to reset through the movable key. There is a gap between the wound aluminum rod and the fixed plate, which facilitates the disassembly of the wound aluminum rod. Furthermore, by rotating the gap between the eccentric wheel and the gear ring through the eccentric wheel shaft, the winding machine can be flexibly adjusted according to the diameter of the wound aluminum rod, ensuring successful wire grabbing every time and preventing wire slippage.
