[0002] The pull rod is a commonly used component in agricultural machinery, which can connect the agricultural machinery traction equipment with the working equipment. The pull rod is usually assembled and welded by the middle connecting rod, the connecting mechanism, the fixing seat and the shock absorbing mechanism. The assembly of the pull rod is usually performed manually. However, the traditional manual welding assembly method is inefficient and only suitable for small batch production. When mass-producing the pull rod, welding robots are usually used for construction.

[0003] Since the lower tie rod has a complicated shape, it is fixed by a special clamp, but the existing clamp can only fix one lower tie rod at a time, resulting in low efficiency of lower tie rod production. In addition, the existing lower tie rod welding clamp is inconvenient to disassemble and assemble the lower tie rod. Summary of the invention

[0004] The present application provides a bracket for assembling a lower tie rod of an agricultural machinery, which can fix multiple groups of lower tie rod components in one clamping, thereby facilitating the welding assembly of the lower tie rods and making the disassembly and assembly of the lower tie rods more convenient, thereby effectively solving the problems in the background technology.

The number of sliders 1 and 2 is not less than one, and the number of sliders 1 and 2 is the same. The outer side of the rectangular frame is provided with vertical quick clamps 1 and vertical quick clamps 2. The vertical quick clamps 1 and vertical quick clamps 2 are symmetrically arranged at both ends of the upper surface of the rectangular frame. A support arm 2 is provided in the middle of the outer side of the rectangular frame, and a positioning rod is provided on the support arm 2. The positioning rod is correspondingly arranged to be plugged into the mounting hole arranged on the lower pull rod.

[0007] Preferably, a positioning motor is installed on the outer side of the U-shaped support frame, and a main shaft is rotatably connected to the upper end of the inner side of the U-shaped support frame. One end of the main shaft is connected to the support frame, and the other end is connected to the output shaft of the positioning motor through a coupling.

[0008] Preferably, the upper surfaces of the slider 1 and the slider 2 are respectively provided with positioning grooves corresponding to the two ends of the outer side surface of the lower pull rod.

[0009] Preferably, the slider 1 and the slider 2 are both fixed to the frame of the rectangular frame by bolts.

[0010] Preferably, a first supporting arm is provided between the second supporting arm and the rectangular frame.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] 1. This bracket for assembling the lower tie rod of agricultural machinery can fix multiple groups of lower tie rod components at one time, which is convenient for welding and assembly of the lower tie rod.
