Referring to fig. 2 to 5, the control arm assembling machine of the present invention includes:

an assembling machine body 10, wherein the assembling machine body 10 is provided with a fixed seat 11, and the fixed seat 11 is provided with a plane 12 for placing a control arm to be processed. Two positioning stoppers 13 are disposed on the plane 12, and a gap is left between the two positioning stoppers 13 for placing a control arm to be processed. The fixing base 11 is provided with a through hole 14, and a cushion cylinder 20 is arranged below the through hole 14. The cushion cylinder 20 includes a cylinder 21 and a rod 22, the rod 22 extends from the cylinder 21 and protrudes to the through hole 14.

Two lateral pressing devices 30 are provided on both sides of the assembling machine body 10. Each lateral pressure device 30 comprises a mobile arm 31 that can move towards or away from the fixed seat 11. Each lateral pressing device has a power source 32, which is a motor in this embodiment, but not limited thereto. A jig 33 is provided at the front end of each moving arm 31, and each jig 33 has a notch whose shape can be set in accordance with the shape of the bush to be assembled. In the present embodiment, the lateral pressurizing device 30 is a hydraulic cylinder, each hydraulic cylinder includes a cylinder and a piston rod, and the jig 33 is disposed at the front end of each piston rod.
