Abstract
The invention relates to a screw lubrication detecting device for a numerical control machine tool, belonging to the field of machine tools and comprising a lead screw, wherein the lead screw is sheathed with a screw frame nut seat and a lead screw nut; a temperature sensor is embedded on the lead screw nut; and the temperature sensor is electrically connected with a programmable logic controller through an A-D converter. The invention has the advantages that the structure is simple; the operation components of the machine tool can be prevented from influencing the production precision of workpieces because of frictional heating caused by poor lubrication condition; and the lead screw can be prevented from operating in a no lubricant state in a long time so as to influence the service life of the integral screw.
Description
Technical field
The present invention relates to machine tool field, at length say it is that a kind of Digit Control Machine Tool lubricates checkout gear with leading screw.
Background technology
As everyone knows, the machine tool technology development advances by leaps and bounds now, improving constantly of equipment manufacture integral level, performance requirement to Digit Control Machine Tool core component ball screw is also more and more higher, machine tool motion component is because the not good frictional heating of lubrication state, all can produce additive error to the machine tool motion shaft position, this will directly influence the positioning accuracy of lathe, thereby influence the machining accuracy of workpiece.If leading screw moves under unlubricated oil condition for a long time, also influential to leading screw itself, the whole leading screw service life of long-play will be subjected to very big influence.In present lathe; most of machine tool lubrication all is to come interrupted oil supply by a lubricating pump; lubricating pump is connected by lubricant passage way with leading screw; if but fracture appears in leading screw oil circuit place, leading screw is lubricated just to be unable to supply, and without any device detect; the leading screw outside also has protective cover protection leading screw; also can't observe lubrication circumstances by naked eyes, for the lathe of automation, use and the machining accuracy of this problem to have a strong impact on lathe.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of Digit Control Machine Tool and lubricate checkout gear with leading screw, avoid machine tool motion component because the not good frictional heating of lubrication state, thereby influence the machining accuracy of workpiece, prevent that simultaneously leading screw from moving for a long time under unlubricated oil condition, thereby influence the service life of whole leading screw.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Digit Control Machine Tool lubricates checkout gear with leading screw, be provided with leading screw, be set with reel nut seat and feed screw nut on the leading screw, it is characterized in that being embedded with on the feed screw nut temperature sensor, temperature sensor is electrically connected with programmable logic controller (PLC) through the A-D converter.
The invention has the beneficial effects as follows, simple in structure, avoid machine tool motion component owing to the not good frictional heating of lubrication state, thereby influence the machining accuracy of workpiece, simultaneously can prevent that leading screw from moving for a long time under unlubricated oil condition, thereby influence the service life of whole leading screw.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention, also is the structural representation of a kind of embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
1. leading screws among the figure, 2. feed screw nut, 3. feed screw nut seat, 4. temperature sensor.
The specific embodiment
In Fig. 1, Fig. 2, the present invention is provided with leading screw 1, is set with reel nut seat 3 and feed screw nut 2 on the leading screw 1, is embedded with temperature sensor 4 on the feed screw nut 2, and temperature sensor 4 is electrically connected with programmable logic controller (PLC) through the A-D converter.Temperature sensor 4 is a resistance becomes certain functional relation with temperature a PT100 temperature sensor, by an A-D converter, convert the analog signals of temperature sensor sampling to digital quantity signal and reach programmable logic controller (PLC), digital control system PLC calculates temperature value according to the program of having finished, whether C.T is higher than the temperature of the normal operation of machine tool lead screw, whether the lubrication oil supply situation of judging machine tool lead screw normal, and according to actual conditions in display alarm of system display place and prompting.
