Abstract
The invention relates to the field of machine tools, in particular to a device and a method for variable-frequency control of the thickness of an oil film on a guide rail. The device comprises a workbench, an oil feed pump and a control system. A static pressure oil chamber is arranged in the workbench, and the oil feed pump is connected with the static pressure oil chamber in the workbench; and the device is characterized by comprising a controller, a frequency converter and a variable-frequency motor, wherein one end of the frequency converter is connected with the variable-frequency motor, and the other end of the frequency converter is connected with the controller; the controller is connected with a control system; and the variable-frequency motor drives the oil feed pump. In the method, the thickness of the oil film is changed via the whole set of system, and the guide rail is always positioned in an optimal status, so that the influence of a load change on a working status of the guide rail is reduced to a large extent; and the method has the advantages of reducing the load, improving the processing precision, and adjusting the thickness of the oil film automatically.
Description
Technical field
The present invention relates to machine tool field, specifically a kind of device and method of variable frequency control slide rail oil film thickness of the lathe that is applied to the worktable technology.
Background technology
Worktable is to have the lubricating oil of certain pressure, is input to the oil pocket on the guide pass, forms the carrying oil film, makes to be in the neat liquid Frotteurism between the guide pass.And embody advantages such as friction factor is low, working stability, long working life, so the worktable technology has obtained using widely in the occasions such as worktable of various heavy duty machine tools.
The rigidity of oil film depends primarily on the thickness of oil film, in the constant rate oil supply system, the oil film thickness of guide rail also changes thereupon when worktable load changes, and this will reduce the rigidity of oil film and the stability of operation, simultaneously machine finish also be had some effects.Therefore, make oil film thickness be in the worktable oil film thickness controlling system of optimal value all the time, will effectively improve the influence of load change the worktable operation.And traditional way all realizes by mechanical mechanism and the artificial pressure method of adjusting, but implements comparatively difficulty, and it is time-consuming to require great effort.
Summary of the invention
The objective of the invention is to solve above-mentioned the deficiencies in the prior art, a kind of device and method that reduces load, raising machining precision, can adjust oil film thickness automatically is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of device and method of variable frequency control slide rail oil film thickness, comprise worktable, oil feed pump and control system, be provided with the static pressure oil pocket in the worktable, oil feed pump is connected with static pressure oil pocket in the worktable, it is characterized in that being provided with controller, frequency converter and variable-frequency motor, and frequency converter one end is connected with variable-frequency motor, the other end is connected with controller, controller is connected with control system, and variable-frequency motor drives oil feed pump, and its processing step is:
(1). send controller to by the default basic parameter value of control system, this parameter can directly be that the load weight value can directly be provided with by touch-screen or binary coding and realizes,
(2). the optimum command value of processing generation by controller sends frequency converter to, and the command value of generation can be the analog quantity voltage signal,
(3). generate command value and pass to frequency converter, frequency converter is according to command request control of conversion electrical motor gearshift,
(4). the oil feed pump rotating speed that variable-frequency motor drives also changes according to command request, and then has realized the delivery rate of control oil feed pump,
(5). from the oil feed pump to the worktable, also just realized adjustment to the oil film thickness in the worktable static pressure oil pocket by the adjustment of delivery rate.
Controller among the present invention preferably adopts the PLC controller, reaches automated programming, the effect of control automatically.
The invention has the beneficial effects as follows: change oil film thickness by whole system, make guide rail be in the state of an optimum all the time, this will reduce the influence of load change to the guide rail duty largely, have the load of reducing, improves machining precision, can adjust advantage such as oil film thickness automatically.
