Dismounting device for fractured connecting rod

Abstract

The invention provides a dismounting device for a fractured connecting rod, belongs to the technical field of automobiles and solves the problems of non-uniform stress and poor using stability of the conventional dismounting device for the fractured connecting rod. The dismounting device for the fractured connecting rod comprises a base, wherein a positioning part 1 used for positioning a small head hole of the fractured connecting rod and a positioning part 2 used for positioning a big head hole of the fractured connecting rod are arranged on the base; a slide block capable of sliding on the base is also arranged on the base; the positioning part 2 consists of a fixed half shaft fixedly connected to the base and a movable half shaft fixedly connected to the slide block; and a driving mechanism capable of driving the slide block to slide in a direction away from the positioning part 1 along a connecting line of the positioning part 1 and the positioning part 2 is arranged between the slide block and the base. The dismounting device for the fractured connecting rod has the advantages of uniform and stable stress, high dismounting quality and suitability for various specifications of connecting rods.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a dismantling device for a broken connecting rod of an automobile engine. Background technique [0002] The connecting rod is an important moving part used to transmit power in the engine. It converts the reciprocating motion of the piston into the rotary motion of the crankshaft. Its small head reciprocates with the piston, the big head rotates with the crankshaft, and the shaft moves at the big and small ends. The composition of the next swing. In addition to the periodically changing gas impact, the connecting rod also bears a large inertial force. This requires the connecting rod to be fatigue-resistant, impact-resistant, and have sufficient strength, rigidity and good toughness. The quality of the connecting rod directly affects the performance and safety performance of the engine. [0003] The big end of the connecting rod is generally made into a split type, that is, ...

AI Technical Summary

Problems solved by technology

However, in the above-mentioned patents, the upper half shaft is pressed by the principle of leverage, so that it is difficult to ensure that the breaking force of the large sleeve is in the direction of breaking, resulting in the failure of the connecting rod to break; Accurate control will also easily lead to the failure of the large end of the connecting rod; and the above disassembly device is only applicable to the disassembly of the same specification of the connecting rod, and the connecting rods of different specifications need to be disassembled by devices of different specifications, which is not very applicable
