Through the foregoing solution, the welding processing efficiency of the steering gear bracket 104 can be improved. It can be understood that the foregoing solution can improve the welding processing efficiency of the steering gear bracket 104.

[0020] In this embodiment, the fixed bottom plate 101 is provided with positioning posts 102, and the positioning posts 102 are used to cooperate with the positioning holes on the bracket bottom plate 103.

[0021] Among them, the bracket bottom plate 103 is detachably connected to the fixed bottom plate 101 and is located on the fixed bottom plate 101. The steering gear bracket 104 is arranged on the bracket bottom plate 103. The front mounting plate 105 is fixedly connected to the fixed bottom plate 101 and is located on the fixed bottom plate 101. The front air cylinder 106 is fixedly connected to the front mounting plate 105 and is located on the front mounting plate 105. The front clamping plate 107 is fixedly connected to the output end of the front air cylinder 106 and is located on the output end of the front air cylinder 106. The side limit components are arranged on both sides of the fixed bottom plate 101, and the pressing components are arranged on one side of the fixed bottom plate 101 close to the steering gear bracket 104. The bracket bottom plate 103 can be directly placed on the fixed bottom plate 101. The front mounting plate 105 is fixed on the fixed bottom plate 101 by positioning pins and bolts. The front air cylinder 106 is fixed on the front mounting plate 105 by bolts. When the front air cylinder 106 pushes out the front clamping plate 107, at this time, one side of the steering gear bracket 104 can abut against the front clamping plate 107, and this position is its welding position. The front clamping plate 107 is a circular plate and is fixed on the output end of the front air cylinder 106 by bolts, and the bolts are countersunk. The side limit components are used for limiting both sides of the steering gear bracket 104, and the clamping components are used for pressing the steering gear bracket 104.

[0022] Secondly, the side mounting plates 108 are fixedly connected to the fixed bottom plate 101 and are located on both sides of the fixed bottom plate 101; the power components are arranged on the fixed bottom plate 101.

Further, place the steering gear bracket 104 at the welding position on the fixed bottom plate 101 and abut it against the front clamping plate 107. Then, control the side cylinder 109 to act, push out the side clamping plate 110 to abut against both sides of the steering gear bracket 104, and perform side limit on the steering gear bracket 104. During side limit, it is necessary for the operator to keep the steering gear bracket 104 in contact with the front clamping plate 107.

Then, welding processing can be carried out. During welding, spot welding can be first performed at the corresponding positions on both sides of the bracket bottom plate 103 and the steering gear bracket 104 for initial connection and fixation. Then, after the front cylinder 106 and the side cylinder 109 are reset, the whole is taken off and then completely welded. The positioning structure provided in this application is conducive to achieving rapid positioning and reducing manual marking, thereby improving the welding processing efficiency of the steering gear bracket 104.
