Abstract
The invention relates to a pretightening force regulating device of a machine table. The pretightening force regulating device of the machine table consists of detection regulation components, a fixing component and a balance nut. Three detection regulation components are uniformly distributed in the fixing component; and each of the three detection regulation components comprises a piezoelectric ceramic, a pressure sensor and a regulating bolt. The piezoelectric ceramic and the pressure sensor are sequentially installed inside the fixing component and are adjustably connected with the fixing component through the regulating bolt. An initial pretightening force of the piezoelectric ceramic can be regulated through the regulating bolt; and the magnitude of the pretightening force can be acquired through the pressure sensor. The pretightening force regulating device of the machine table can be used for regulating the pretightening force between a lead screw nut and a lead screw of the machine table conveniently, accordingly allowing the machine table to have different pretightening forces under different machining conditions, thereby increasing the service life and the adaptability of the machine tool.
Description
Technical field
The present invention relates to a kind of platen pre-tightening force adjusting device, especially a kind of device being undertaken that by adjusting bolt, pressure sensor and piezoelectric ceramics pretightning force between feed screw nut and leading screw is regulated.
Background technology
The processing characteristics of pretightning force on lathe of the different size of platen has different impacts, high pretightning force will improve the rigidity of feed system, lathe will have better processing stability and precision, but too high pretightning force makes lathe wearing and tearing aggravation, thus the fault causing lathe too early and inefficacy.In addition, for the lathe that newly dispatches from the factory, pretightning force is comparatively large, and weares and teares with continuous with the use of lathe, and pretightning force meeting constantly reduction, therefore realizes a kind of effective and necessary mode that the adjustment of platen pretightning force is raising lathe life-span and flexibility (adaptability) of operation energy.
At present, domestic also do not have this type of pretightning force for platen to carry out the convenient device regulated, therefore more difficult when adjusting tool workbench pretightning force.If installation pretightening force adjusting device on ball-screw, can regulate the pretightning force of platen easily, to reach desirable pretightning force size, thus improve the processing characteristics of lathe.
Summary of the invention
The present invention will provide a kind of platen pre-tightening force adjusting device, for solving the technical problem that platen pretightning force is inconvenient to regulate.
For achieving the above object, technical scheme of the present invention is:
A kind of platen pre-tightening force adjusting device, be made up of detection adjusting part, fixation kit and balance nut, three described detection adjusting parts are evenly equipped with in described fixation kit, described detection adjusting part comprises piezoelectric ceramics, pressure sensor and adjusting bolt, described piezoelectric ceramics and pressure sensor are contained in fixation kit successively, and be connected with adjusting bolt and fixation kit are adjustable, regulate the initial pretightning force of piezoelectric ceramics by adjusting bolt, and obtain pretightning force size by pressure sensor.
Described fixation kit comprises base plate dish, tray deck and adjustment disk, tray deck two ends are by three circumferential uniform guide blots fixed base plate dishes and adjustment disk respectively, wherein base plate dish and feed screw nut are bolted, and adjustment disk and balance nut are bolted.
Described fixation kit is connected with machine tool ball screw with feed screw nut by balance nut, and wherein, described fixation kit is axially tight with balance nut clip by feed screw nut.
The initial pretightning force of described three piezoelectric ceramics is consistent.
The invention has the beneficial effects as follows: the present invention forms by detecting adjusting part, fixation kit and balance nut.Detect adjusting part and comprise piezoelectric ceramics, pressure sensor and adjusting bolt; Fixation kit is made up of base plate dish, tray deck and adjustment disk three discoid parts, for installation and the location of piezoelectric ceramics, pressure sensor and adjusting bolt, base plate dish and table lead screw nut are bolted, adjustment disk and balance nut are bolted, fixation kit circumference is fixed by three guide blots, and whole device is with movable workbench.The present invention can be used for pretightning force between adjusting tool table lead screw nut and leading screw easily, thus makes lathe have different pretightning forces at different processing conditions, improves lathe service life and adaptability.
The invention provides a kind of platen pre-tightening force adjusting device, to be arranged on machine tool ball screw and workbench connects, can pretightning force size easily between adjusting operating platform feed screw nut and leading screw, thus improve the performance of lathe.
