Stable four-axis robot for vehicle-mounted camera automatic screw locking machine

The utility model relates to the technical field of vehicle-mounted camera machining, in particular to a stable four-axis robot for an automatic screw locking machine of a vehicle-mounted camera. According to the technical scheme, the device comprises a base, a Z-axis linear motor and an X-axis linear motor, two sets of supports are installed on the two sides of the outer portion of the base through bolts, the X-axis linear motor is fixedly installed on the tops of the supports, a Y-axis linear motor is movably installed at the output end of the X-axis linear motor, and a clamping piece is movably installed at the output end of the Y-axis linear motor; and a cushioning sleeve is mounted in the clamping piece. When the electric screw machine is used, due to the fact that the cushioning sleeve is arranged between the clamping piece and the electric screw machine when the clamping piece fixedly clamps the electric screw machine, the stability of the clamping piece clamping the electric screw machine can be impro
