Problems solved by technology

[0005] However, in the testing process, there are the following problems. One is that the recovered crankshafts are inconsistent in size and specification. The existing crankshaft testing equipment is mainly used in the manufacturing process. Generally, it is only for crankshafts of specific specifications and models, and cannot be used universally for different specifications. Moreover, the detection accuracy of this type of crankshaft detection equipment is very high and the price is expensive. In fact, the equipment in the initial detection link of the recycled crankshaft does not require high precision, but requires the cost to be as low as possible; the second problem is that the existing detection device It is divided into the connecting rod journal detection device of the crankshaft and the main journal detection device of the crankshaft. It needs to be separated into two devices for detection, the detection operation is complicated, and the detection efficiency is low.

Abstract

The invention discloses a special testing device for recycling crankshafts of scrapped automobile engines, which belongs to the technical field of energy saving and environmental protection. The type fixed assembly includes a support piece, an adjustment piece, a guide piece and a fixed piece. The adjustment piece adjusts the central axis of the connecting rod journal or main journal of the engine crankshaft to coincide with the central axis of the driving end of the rotating drive assembly; the top of the rotating drive assembly is connected with a Height adjustment assembly; the drive end of the height adjustment assembly is provided with a multi-point detection assembly for cylindricity detection; through the above method, the present invention realizes the continuous detection of the main journal and connecting shaft diameter of the engine crankshaft recovered from scrapped vehicles, the detection process is simple, and the detection efficient.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a special testing device for recycling crankshafts of scrapped automobile engines in the field of energy saving and environmental protection. Background technique [0002] The "Administrative Measures for the Recycling of Scrap Motor Vehicles" has come into effect on June 1, 2019. The "Measures" clearly stipulate that the "five assemblies" can be recycled through remanufacturing, including the engine, steering gear, transmission, front and rear axles, and frame. If the "five major assemblies" meet the remanufacturing conditions, they can be sold to enterprises with remanufacturing capabilities for recycling in accordance with relevant state regulations. Parts other than the "five assemblies" of dismantled scrapped motor vehicles, which meet mandatory national standards for the protection of personal and property safety and can be used continuous...
