The utility model relates to a mistake-proof
assembly device for steering gear parts, and belongs to the technical field of steering gear detection equipment. The device is composed of a working table, a supporting frame, rack protective cover locking mechanisms, a left outer
ball joint storage table, a right outer
ball joint storage table, a placing frame and a workpiece clamping mechanism, the supporting frame is arranged on the working table in a cross-line mode, and the rack protective cover locking mechanisms are symmetrically arranged at the positions, corresponding to the working table, of the supporting frame. A workpiece clamping mechanism is arranged on the corresponding
workbench between the rack protective cover locking mechanisms, a left outer
ball joint storage table is arranged on the
workbench on one side of the workpiece clamping mechanism, and a right outer ball joint storage table is arranged on the
workbench on the other side of the workpiece clamping mechanism; placing frames are respectively arranged on the working table on the outer sides of the left outer ball joint storage table and the right outer ball joint storage table, and torque wrenches are placed on the placing frames. According to the steering gear part mistake-proofing
assembly device, the production efficiency of steering gears is effectively improved, and meanwhile the yield of steering gear products is improved.
