Problems solved by technology

[0008] Chinese patents (203721699U) and (203576109U) disclose a clamping device for discs, a rotating platform for discs and a magnetic levitation viewing platform, which can only achieve rotation but not translation, and cannot meet the requirements of curve welding
The platform realizes suspension and translation, but this device is suspended through the electromagnetic permanent magnet hybrid poles set on the four corners. If it is applied to a welding positioner to achieve long linear translation, the platform must be very large, and once the platform is moved out The electromagnetic permanent magnet hybrid poles at the four corners can no longer be suspended, and its translation is realized by guiding electromagnets and linear propulsion systems. The movement response time is long, and the accuracy and stability cannot meet the requirements of welding positioners.

Abstract

The invention discloses a magnetic suspension and magnetic drive multi-axis flexible transposition device. The device can achieve magnetic force suspension, magnetic force drive rotation and horizontal movement through the arrangement of a suspension device, a rotation device and a horizontal movement device. After the device stably works, no mechanical contact exists among the structures in the horizontal movement and rotation process, abrasion caused by mechanical friction is avoided, and the problem of platform shaking caused by crawling and uneven track connectors due to mechanical contact is solved. When the device is used for welding, the welding requirement for welding lines of any lengths can be met, welding curve welding is achieved through coordination of the rotation speed and the horizontal movement speed, and excellent dynamic response and motion precision are achieved. The magnetic suspension and magnetic drive multi-axis flexible transposition device is suitable for precise welding, movement and rotation of workpieces such as complex and small flanges and end sockets, and meanwhile the magnetic suspension and magnetic drive multi-axis flexible transposition device is suitable for cutting, checking and the like of medium-small-sized workpieces.

Description

technical field [0001] The invention belongs to the field of welding displacement, in particular to a magnetic levitation and magnetic drive multi-axis flexible displacement device. Background technique [0002] From the perspective of current processing and manufacturing, the welding process is still an important processing method in the processing and manufacturing industry for a long period of time. As an auxiliary equipment in welding equipment, welding positioner plays an indispensable role in improving welding quality and welding efficiency. However, the current welding positioners are mechanical and electrical integrated positioners, that is, the drive motor drives the gear pair to drive the worktable movement or the motor drive shaft movement drives the worktable movement. These methods are all in mechanical contact. The friction of the contact surface and the wear of the gears will cause problems such as reduced precision, energy loss, and a large amount of heat.
