Cutter platform for grinding combined machining machine tool

Abstract

The invention discloses a cutter platform for a grinding combined machining machine tool. The cutter platform comprises a precise cross-shaped sliding platform which is used for doing longitudinal motion and horizontal motion on a precise numerical control lathe, wherein the length of a horizontal supporting plate of the precise cross-shaped sliding platform along the horizontal direction of a large supporting plate is greater than the horizontal length of the large supporting plate; a turning cutter platform, an end surface normal grinding device and an inner hole grinding device are arranged in parallel on the horizontal supporting plate; at least the end surface normal grinding device is arranged on a first sliding plate which is driven to do the longitudinal motion by a third driving system; the axial lead of the indexing rotation center of the turning cutter platform and the axial lead of a main shaft of the inner hole grinding device are parallel to the axial lead of the main shaft of the lathe; and the axial lead of the main shaft of the end surface normal grinding device is spatially and vertically intersected with the axial lead of the main shaft of the lathe. By the cutter platform, workpieces can be subjected to grinding combined machining on the same numerical control lathe, so that the workpieces can be mounted and clamped at a time, machining errors caused by mounting and clamping errors can be eliminated, the machining accuracy of a product can be ensured, the manufacturing difficulty of the machine tool is reduced, and the manufacturing cost is correspondingly reduced.

Description

technical field [0001] The invention relates to the field of precision numerical control machine tools, in particular to a tool table of a turning-grinding compound processing machine tool. Background technique [0002] In the field of mechanical processing, lathes are used for turning and grinding machines are used for grinding. Turning and grinding of workpieces are usually carried out on lathes and grinding machines step by step, and the same workpiece is separately processed on different machine tools. The machining requires re-clamping of the workpiece, and the clamping error formed by the re-clamping will lead to processing errors. The errors caused by this clamping and processing will not affect the ordinary workpieces that do not require high precision. The pass rate of ordinary workpieces, but for precision-machined workpieces with high precision requirements, the errors generated by turning and grinding in the above-mentioned way will have a greater impact on the a...

Problems solved by technology

This "inverted turning and grinding center" has made an important contribution to the field of efficient machining of hardened materials that are usually difficult to cut. However, the main structure of this "inverted turning and grinding center" is: the main shaft is inverted, and the main shaft supporting member simultaneously shoulders the X-axis, The motion mechanism of the Z axis, in order to achieve high rigidity, especially high rigidity in the motion state, this structure requires a very high manufacturing level in manufacturing, and has a high dependence on high-power, high-rigidity electric spindle

Due to the extremely high requirements on the manufacturing level of this "inverted turning and grinding center", the manufacturing of this machine tool is difficult, the manufacturing cost is high, and the sales price is extremely expensive, which is unaffordable for ordinary enterprises.

As a result, areas where modern industry started late have great difficulties in the production and use of "inverted turning and grinding centers". Therefore, there are great obstacles in the application of turning and grinding combined processing by comprehensively applying the advantages of turning and grinding.

How to reduce the manufacturing cost of machine tools capable of turning-grinding composite processing, so that the turning-grinding composite processing technology can be widely promoted, so that ordinary enterprises can also apply the turning-grinding composite processing technology to process hardened materials is a long-term research in the field of machinery manufacturing , development problems that have not yet been effectively resolved
