Controlling means of follow -up spray gun frame

The utility model provides a controlling means of follow -up spray gun frame, includes: a mount, a linear mechanism, a stack and a servo mechanism. Have a pedestal on this mount, two each rigid coupling of side of this pedestal have a fixed block, and each rigid coupling has a slider on this two fixed block. This linearity mechanism rigid coupling is on this pedestal. This stack connects with this linearity mechanism group, and two guide rails of this stack are along with this linearity mechanism is driven and slides on two sliders. This servo mechanism disposes in this linearity mechanism one side to it constitutes linear displacement to drive this linear machine. When the displacement of platform truck bearing wheel circle, the outside servo motor slew velocity of controller in order to read the platform truck to according to the stack in this linearity mechanism of servo mechanism drive of slew velocity control of the servo motor of platform truck along with paint spraying is carried out in the synchronous
