Volute spiral spring type swing device with gap removing function

Abstract

The invention discloses a volute spiral spring type swing device with a gap removing function. The volute spiral spring type swing device aims to solve the problems that a worm gear reducer is adopted for a swing device on an existing full-automatic cladding robot, after the swing device works for a long time, gaps may be generated between engaged teeth in the transmission process of a worm gear and a worm, consequently, a swing head wobbles, swinging cannot reach the required angle, and the repairing effect of the full-automatic cladding robot on a water wall is influenced. A motor is fixedly arranged outside a shell; a worm is arranged in the shell and is connected with the output shaft of the motor through a coupler; a worm gear is engaged with the worm and is fixedly arranged on a driven shaft; a gap exists in the upper end of the driven shaft along the axis; a volute spiral spring is arranged outside the shell and is wound on the driven shaft; the inner end of the volute spiral spring is inserted in the gap; the outer end of the volute spiral spring is fixed to a screw; the screw is in threaded connection with a fixing plate; and the shell is fixedly arranged on the fixing plate. The volute spiral spring type swing device is used for the full-automatic cladding robot.

Description

technical field [0001] The invention relates to an oscillating device, in particular to a scroll spring type oscillating device with the function of eliminating backlash. Background technique [0002] The water wall is the main pressure-bearing part of the circulating fluidized bed boiler, mainly used to absorb the radiant heat of the boiler. During the operation of the circulating fluidized bed boiler, the flow direction of the solid material flowing down the inner wall of the furnace changes in the junction area, so The surface of the water-cooled wall is scoured. After a long period of scouring, the wall of the water-cooled wall is worn and thinned, and the strength is reduced. In addition, in the transitional area, because the solid material flowing down the wall is opposite to the solid material moving upward in the furnace, a vortex is locally generated. The swirling flow causes abrasion to the water cooling wall and shortens the service life of the water cooling wall....

AI Technical Summary

Problems solved by technology

[0003] The present invention is to solve the problem that the oscillator body of the oscillator on the existing fully automatic welding robot adopts a worm gear reducer. After the oscillator body works for a long time, there will be a gap between the meshing teeth of the worm wheel and the worm during the transmission process. As a result, the swing head shakes, so that the swing does not reach the required angle, which affects the effect of the automatic cladding robot on the repair of the water wall. A scroll spring swinger with anti-backlash function is provided.
