Abstract
The invention provides a heavy machine tool tailstock jacking force detection method. The specific detection method is applicable to ordinary or numerical control horizontal machine tools of different specifications and is most beneficial to heavy and extra-heavy machine tools. The device improves the reliability and safety of the machine tools, so that the maintenance difficulty of workers is relieved, and the use cost and maintenance cost of the machine tools are lowered.
Description
Technical field
The present invention relates to machine tool accuracy characterization processes technical field, be specifically related to a kind of heavy machine tool tailstock pressure detection method.
Background technology
At present, known Tailstock of Heavy Horizontal Lathe pressure is that depended on pressure entry is surveyed, the pressure size measured is drawn according to the Weight computation of workpiece by machine operation person, and the size variation of pressure that the workpiece of Different Weight needs in process is different, operator is needed to observe the change of manometric pressure indicating value at any time, such operation not only bothers, and once pressure is observed occur that deviation of reading can cause serious security incident not in time, to enterprise or employee, these are all do not wish to occur, particularly heavy, the accurate observation of superduty sleeping carriage tailstock pressure runs most important to machine safety.
Summary of the invention
The object of the present invention is to provide a kind of heavy machine tool tailstock pressure detection method, which overcome the tailstock pressure caused due to the inaccurate and operate miss of theory calculate inadequate, thus the economic loss caused and employee's unexpected injury, this mechanism has that structure is simple, easy to adjust, reliability is high, the features such as stationarity is good, thus effectively improve the reliability of lathe, alleviate the maintenance intensity of workman, reduce cost of use and the maintenance cost of lathe.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of heavy machine tool tailstock pressure detection method, include heavy machine tool tailstock pressure checkout gear, it is top that heavy machine tool tailstock pressure checkout gear includes spindle flange, front connecting axle, pillar dynamometer, rear connecting axle, tailstock flange is top, top and the front connecting axle of described spindle flange is connected, the other end of front connecting axle is connected with one end of pillar dynamometer, the other end of pillar dynamometer is connected to one end of rear connecting axle, it is top that the other end of described rear connecting axle is connected with tailstock flange, pillar dynamometer is electrically connected with pillar dynamometer display, its concrete detection method step is:
(1) structure member of detection method is assembled into assembly;
(2) detection method top is stuck between machine tool chief axis and tailstock;
(3) according to the demarcation numerical value on lathe pressure label, by the setting of tailstock guidance panel, tailstock is maximum holds out against force value, then moves tailstock pressing tailstock pressure detection method by tailstock guidance panel;
(4) first high pressure pumping station to be started by tailstock guidance panel when mobile tailstock, by the control of high pressure pumping station, the piston rod of tailstock compression hydraulic cylinder is moved downward, thus tailstock compression hydraulic cylinder and bed ways are existed in gap, mobile tailstock pressing tailstock pressure detection method;
(5) when the pressure of tailstock exceedes the numerical value of pressure label 7 regulation, the power-off of tailstock mobile motor, tailstock stops holding out against, and now high pressure pumping station quits work, and tailstock compression hydraulic cylinder resets under the effect of disc spring, thus makes tailstock be clamped on lathe bed;
(6) amesdial 1 is adjusted be placed on tailstock rear end, record initial value, keep 4 hours in this case, then according to the numerical value of pillar dynamometer display display, the numerical value detected in conjunction with amesdial judges whether the clamping force that need adjust tailstock compression hydraulic cylinder, if the display numerical value of pillar dynamometer display in ± 0.5% scope, amesdial display numerical value belongs to normally within 0.04mm, otherwise needs the clamping force readjusting tailstock compression hydraulic cylinder.
The invention has the beneficial effects as follows: structure of the present invention is simple, which overcome the tailstock pressure caused due to the inaccurate and operate miss of theory calculate inadequate, thus the economic loss caused and employee's unexpected injury, effectively improve the reliability of lathe, alleviate the maintenance intensity of workman, reduce cost of use and the maintenance cost of lathe.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete exemplifying embodiment, setting forth the present invention further.
