Driving device based on center distance adjusting mechanism and welding positioner

Abstract

The invention relates to a driving device based on a center distance adjusting mechanism, which comprises a flange plate, a motor mounting plate, a speed reducer mounting plate and an eccentric plate, and the motor mounting plate and the speed reducer mounting plate are respectively arranged on two sides of the eccentric plate; a gap between the center line of the motor mounting disc and the center line of the eccentric disc is an eccentric distance; the mounting plate is used for fixing the flange plate; the driving module comprises a servo motor and a speed reducer, the servo motor is mounted on the motor mounting disc, and the speed reducer is mounted on the speed reducer mounting disc; when the driving module is installed, the flange plate rotates around the center line of the eccentric disc to drive the speed reducer to rotate around the center line of the eccentric disc, and when the numerical value of the eccentric distance reaches a set value, the flange plate is fixed to the installation plate. According to the invention, a horizontal movement mode is replaced by rotary movement, so that the adjustment difficulty and the dependence on assembly workers are reduced, the adjustment efficiency is greatly improved, and the adjustment quality is easier to guarantee.

[0003] As one of the important equipment for automatic welding, the welding positioner plays a pivotal role. It can realize the spatial position transformation of the workpiece to be welded and increase the flexibility of welding. However, the positioning accuracy and repeat positioning accuracy of the welding positioner in the working process It must be guaranteed that the center distance of the meshing gears must be within a certain range of error during the manufacturing process. Relying on machining to ensure this accuracy is expensive and the manufacturing cycle is prolonged

[0004] However, the center distance adjustment of the current welding positioner mostly adopts the horizontal movement method, which requires two adjustment rods to be carried out synchronously. It is difficult to ensure that the two adjustment rods move at the same distance, and the adjustment level of the workers is high, and the accuracy is difficult to guarantee.
