Problems solved by technology

At present, the positioning on the combination machine tool is mainly a position switch or a proximity switch. This type of switch will cause poor positioning accuracy due to the inertia of the sliding table movement, chip resistance and the characteristics of the switch loop action; the change of the switching characteristics will easily cause the sliding table to overshoot and stop. Or stop prematurely, the positioning accuracy is poor, the ideal accuracy cannot be achieved, and the production demand cannot be met

Abstract

The invention discloses a high-precision locating device for a machine tool, and relates to the technical field of combined machine tool locating devices. The high-precision locating device comprisesa rack. A spindle box is arranged on the rack and provided with a tool. A fixed locating check block mechanism is arranged on one side of the spindle box. A guide rail is arranged at the position, below the tool, of the rack and is provided with a sliding table. A workpiece is mounted on the upper portion of the sliding table. An adjustable locating check block mechanism is arranged on one side ofthe sliding table. A power mechanism is arranged at the position, at one end of the sliding table, of the rack and drives the sliding table to slide. The high-precision locating device solves the problem of the poor locating precision of a common locating switch and is high in locating precision, and production requirements are met; and the high-precision locating device is simple in structure and control circuit and low in production cost.

Description

technical field [0001] The invention relates to the technical field of positioning devices for combined machine tools, in particular to a high-precision positioning device for machine tools. Background technique [0002] Combined machine tool refers to a special machine tool composed of serialized and standardized general-purpose components and a small number of special components. Combined machine tools are suitable for processing one or several processes of one or several similar parts in mass production. The combination machine tool needs to control the running position accuracy of the slide table on the machine tool. At present, the positioning on the combination machine tool is mainly a position switch or a proximity switch. This type of switch will cause poor positioning accuracy due to the inertia of the sliding table movement, chip resistance and the characteristics of the switch loop action; the change of the switching characteristics will easily cause the sliding ...
