A machine tool for rough and fine countersinking of inner and outer spherical surfaces and end faces of a differential case

Abstract

The invention relates to a machine tool for coarse and fine reaming of the inner spherical surface, the outer spherical surface and the end face of a differential shell. The machine tool solves the problem that an existing machine tool for manufacturing differential shells is low in machining efficiency, poor in universality, and not suitable for machining of differential shells of different types in a small-scaled mode. The machine tool comprises a machine tool body. A left sliding table mechanism, a middle sliding table mechanism, a right sliding table mechanism and a mechanical arm mechanism are arranged on the machine tool body. The left sliding table mechanism, the middle sliding table mechanism and the right sliding table mechanism are arranged on a slide rail of the machine tool. The mechanical arm mechanism is arranged on the rear portion of the middle sliding table mechanism. A differential shell clamp is arranged on the middle sliding table mechanism. The left sliding table mechanism comprises a left sliding table which slides leftwards and rightwards on the slide rail and is fixed to the slide rail. A left connection rod is rotatably fixed to the right portion of the left sliding table and connected with a motor located on the left sliding table through a transmission case. A first hydraulic cylinder is connected between the left side of the left sliding table and the machine tool body. The machine tool is suitable for small-scale production after being regulated in a one-off mode, is high in automatic production degree, low in cost, environmentally friendly, low in labor intensity, high in efficiency and suitable for small-scale production, and saves energy.

Description

technical field [0001] The invention relates to the field of differential case processing, in particular to a machine tool for rough and fine spot-sinking of the inner and outer spherical surfaces and end faces of the differential case. Background technique [0002] With the development of social economy, people's living standards are getting higher and higher. Cars have entered most families. Now there are many kinds of cars in society, and the production quantity is also increasing year by year. However, the differential case is a must for cars. One of the indispensable parts, so the demand for differential housings has also increased sharply. At present, the differential housings are developing in the direction of small batches and multiple varieties, but at present, the processing of differentials in my country is generally used. The lathe is manually processed by clamping the workpiece with a triangular chuck. This processing method has low efficiency and poor versatility...
