Horizontal lathe for machining cylindrical eccentric part and method adopted by same

Abstract

The invention provides a horizontal lathe for machining a cylindrical eccentric part and a method adopted by the horizontal lathe, which relate to a machining mechanism for machining the cylindrical eccentric part, in particular to a horizontal lathe for machining the cylindrical eccentric part and a machining method of the cylindrical eccentric part. Through the horizontal lathe and the machining method, the machining efficiency and the machining accuracy of the cylindrical eccentric part are improved; the production cost is reduced; the machining of the cylindrical eccentric part by the horizontal lathe is realized; and the needs for machining the cylindrical eccentric parts with different specifications and lengths are satisfied. The horizontal lathe comprises a horizontal lathe, and one side of a lathe body of the horizontal lathe is provided with a lathe headstock and the other side thereof is provided with a lathe tailstock; the lathe headstock is provided with a clamping disk with clamping jaws; correspondingly, the lathe tailstock is provided with a tip; and a tool feed rest is arranged on a guide rail of the lathe body between the lathe headstock and the lathe tailstock. The horizontal lathe has structural key points as follows: a roller support transmission combined with the guide rail of the lathe body is arranged; and the tool feed rest is used for fixing an excircle turning tool or an inner-hole turning tool.

Description

technical field [0001] The invention relates to a processing mechanism for cylindrical eccentric parts, more specifically, to a horizontal lathe for processing cylindrical eccentric parts and a processing method for the cylindrical eccentric parts. Background technique [0002] Cone crusher is an ore crusher developed in the last century. It has the characteristics of simple structure, convenient control, large crushing particle size, easy disassembly and maintenance, and is widely used in mining and metallurgy and other fields. Cylindrical eccentric parts-eccentric sleeve assembly is the main part of the cone crusher to complete the crushing. Generally, the eccentric sleeve assembly is mainly composed of eccentric shaft, eccentric sleeve, key, cage, gear, and gear mounting frame. [0003] Due to the length of the cylindrical tapered sleeve is too long, the diameter of the eccentric taper hole is too small, the machining axis of the inner hole is not the same axis as the mac...

AI Technical Summary

Problems solved by technology

[0003]Because the length of the cylindrical taper sleeve is too long, the diameter of the eccentric taper hole is too small, the machining axis of the inner hole is different from the machining axis of the outer circle, and the inner hole One side is tapered at 1:24, which makes the processing of the inner taper hole and outer circle of the eccentric sleeve more complicated

[0004] Whether the traditional method is to process the inner hole or the outer circle first, it is difficult to determine the design of the tool and control the machining of the eccentric hole

Under normal circumstances, deep hole processing is mostly completed by drilling, reaming and boring on a drilling machine or a boring machine, but this processing method can only process straight holes, and it cannot be realized for eccentric tapered holes; It can be processed by designing and lengthening the tool bar, but because the tool bar is too long, the tool will give way during the cutting process, so there is no special tooling fixture for guarantee, the processing is very difficult, and the processing accuracy and processing efficiency are very low.

Therefore, only numerical control equipment can be used for processing. Conventional processing fixtures are time-consuming, and it is difficult to guarantee the complex processing process of the product and the processing quality of the parts.
