Description

Technical Field

[0001] The utility model belongs to the technical field of parts processing, and more specifically relates to an auxiliary hole-opening device for a steering tie rod. Background Art

[0002] The steering tie rod is an important part of the automobile steering system. The steering tie rod ensures the synchronous movement of the two wheels. The steering tie rod needs to be drilled during processing and manufacturing. An auxiliary drilling device is required when drilling the hole in the steering tie rod. A hole is made on the steering tie rod, and the steering tie rod hole is clamped on the protrusion of the auxiliary drilling device. Then the steering tie rod is fixed on the auxiliary drilling device, and the drilling device performs drilling processing on the steering tie rod.

[0003] According to CN202322689998.8, the utility model discloses a novel fixture suitable for machining a steering tie rod arm. The fixture comprises a base, a plurality of limit blocks and a plurality of insert barrels fixed to the base, a slot defined in the limit block, one end of the steering tie rod arm embedded in the slot, a first fixing member threadedly connected to the slot, a first pressure plate sleeved on the first fixing member for pressing and limiting the steering tie rod arm, a bolt threadedly connected to the insert barrel, the end of the bolt supporting the steering tie rod arm, and a third fixing member threadedly connected to the base. The utility model enhances the machining stability of the steering tie rod arm in a machining center, ensuring that the dimensions of Class A key components meet the design accuracy requirements. This achieves innovative design breakthroughs in tooling design and addresses key issues in solving the difficult machining problems of serialized steering tie rod arms.

[0004] Based on the above, the existing auxiliary hole opening device generally fixes the steering tie rod through a pressure block structure. When the steering tie rod is fixed on the device, the staff needs to clamp the steering tie rod hole inside the protrusion, and then use the pressure block to fix the steering tie rod. When the staff takes the steering tie rod from the device, the staff needs to slide the pressure block to loosen the steering tie rod, and then separate the steering tie rod hole and the protrusion, and then separate the steering tie rod and the device. The operation of the staff taking the steering tie rod is relatively cumbersome. Utility Model Content
