Problems solved by technology

[0005] The tool adjustment device mentioned above uses the adjustment screw rod 304 to rotate relative to the tool bar seat 303 to drive the tool bar 302 to move obliquely. It is difficult to adjust the tool height in a micron-level or even smaller range with the screw rod, and the thread fit will be damaged after a long time. Elastic fatigue and relaxation occur, which affects the exact position of the tool 301, so it is not easy to achieve precision or ultra-precision machining

Abstract

A bit tool controlling device includes the bit tool, tool seat and a fixing seat. The bit tool is installed in the tool seat and the fixing seat includes a base board and a cantilever. The tool seat is installed in the cantilever. The piezoelectric ceramic which can extend to push the cantilever to change the location of the bit tool is installed between the base plate and the cantilever. The length of the piezoelectric ceramic can be changed in a smaller range to accurately adjust the location of the bit tool.

Description

【Technical field】 [0001] The invention relates to machine tools, in particular to a tool adjusting device for the machine tool. 【Background technique】 [0002] Traditional machining methods include turning, milling, planing, and grinding, which are used to process the shape of molds and other workpieces. These processing methods must be carried out on their corresponding machine tools, such as lathes, milling machines, planers, and grinders. The corresponding tool is installed on the machine tool, and when the machine tool is started, the tool can process the surface or inside of the workpiece. [0003] With the continuous advancement of technology, higher requirements have been put forward for the precision of machining, and precision and even ultra-precision machining have been widely used. To achieve such a high precision, in addition to the static precision of the machine itself, the precision of the tool and the position adjustment of the tool will have a direct impact...
