There are roll-type variable-bit machine, rotary head and tail, head and tail lift rotary, head and tail can tilt and dual rotary and other forms of variable-bit machine, through the work of lifting welding positioner, rotating, flipping the workpiece welded or assembled in the best position to form an automatic welding machine and other ancillary welding operation, the robot can also be used as peripheral equipment and robotic force supporting the welding automated welding positioner auxiliary, according to user requirements for different types of artifacts and Design custom special positioner. According to the technical requirements of points: 1, rotary drive (1) of the rotary drive should realize stepless, and reversed. Speed ??fluctuations (2) in the rotation speed range, under maximum load does not exceed 5%. 2, the tilt drive (1) tilt drive should be smooth, no jitter at maximum load, the machine can not overturn. Q exceed 25kg maximum load displacement machine, should have the power drive function. (2) limiting device shall be provided to control the tilt angle mini positioner, and the angle indicator. (3) To tilt mechanism with self-locking feature, do not slide under maximum load, safe and reliable. Micro-positioner, Wuhan three Rainbow Heavy Industries (certified), variable-bit machine provided by Rainbow Heavy Industries Co., Ltd., Wuhan three. Wuhan three Rainbow Heavy Industries Ltd. (www.whshzg.com) is Wuhan, a leader in welding equipment and equipment over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
