Technical field
The present invention relates to a kind of numerical control machine slide rail accuracy detecting devices.
Background technique
Lathe refers to the machine of manufacture machine, also known as machine-tool or toolroom machine, traditionally abbreviation lathe.It is generally divided into gold
Belong to stock-removing machine, forging machine tool and wood craft machines etc..There are many method of processing equipment part in modern mechanical manufacturing: except cutting adds
Outside work, there are also casting, forging, welding, punching press, extruding etc., as long as belonging to, required precision is higher and surface roughness requirements are thinner
Part generally all need to finally be processed on lathe with the method for cutting.Lathe rises in the construction of national economic modernization
Significant role.Automatic lathe can be automatically performed the multistage manufacturing processes of middle-size and small-size workpiece, energy automatic loading/unloading, weight by certain procedures
It is added with the same workpiece of work a batch, is suitable for large quantities of, mass production.
All kinds of lathes are usually made of following essential part: bearing part, for installing and supporting other component and workpiece,
Bear its weight and cutting force, such as lathe bed and column；Gear, for changing the speed of main motion；Feed mechanism is used for
Change the amount of feeding；Spindle box is to install machine tool chief axis；Knife rest, tool magazine；Control and steerable system；Lubricating system；Cooling system.
Bearing and guided-moving component are known as guideway along the part that certain track moves, and are also often simply called guide rail.Fortune
The motion profile of dynamic component has straight line, circle or curve, and rolling thrust bearing can be classified by rolling round guide, and curvilinear guide is in machinery
Few application.Guide rail is a highly important component in the machine, particularly important in lathe.The machining accuracy and guide rail of lathe
Precision has direct connection, the precision machine tool of small lot production, and the labor content of guide rail accounts for entire machine tooling workload
40% or so.Moreover, guide rail repairs very difficult once damaging.By kinematic principle, so-called guide rail be exactly by moving link about
Device of the beam to only one freedom degree.Guide pass on the support members is set in guideway to hold guide face, referred to as quiet guide rail, it
It is long；Another guide pass is located on moving link, and referred to as dynamic guide rail, it is shorter.Moving link with dynamic guide rail is normal
Referred to as workbench, slide unit, common guide pass have plane and arc surface.Arc guide rail face constitutes cylindrical slideway；It is different flat to lead
Rail level combination, constituting the friction between rectangular guideway face is that sliding friction person is known as slide rail, and people is set between guide pass and rolls member
Part makes friction be changed into rolling friction person and is known as rolling guide.Guide rail is divided into enclosed and open type, and closed guideway can bear to incline
Torque is covered, and opened slide then cannot.
Summary of the invention
Goal of the invention: being directed to the above-mentioned prior art, propose a kind of numerical control machine slide rail accuracy detecting device, is used for detection machine
The depth of parallelism variable quantity of bed guide rail.
Technical solution: a kind of numerical control machine slide rail accuracy detecting device, steady for machine tool are slidably connected with machine tool guideway, institute
Numerically-controlled machine tool lathe bed two sides are stated equipped with vertical datum plate, the two sides of the steady for machine tool are respectively fixed with a laser displacement
Sensor, two laser displacement sensors are symmetrical arranged about the steady for machine tool, the laser displacement sensor
Vertical datum plate described in collimation laser exit end face, the output end of two laser displacement sensors are connected to host computer,
The host computer calculates lathe guide rail parallelism variable quantity according to the output signal of the laser displacement sensor.
Further, the host computer includes display module and alarm modules, and the display module is for showing lathe
Guide rail parallelism changes magnitude, and when the machine tool guideway depth of parallelism variable quantity is greater than preset value, the alarm modules are for sending out
Warning information out.
It further, further include the sampling interval control module for connecting the host computer, for controlling the laser displacement
The sampling period of sensor.
Further, the host computer is arranged on the housing case of numerically-controlled machine tool, the laser displacement sensor it is defeated
Signal is transferred to the host computer by wireless transport module out.
The utility model has the advantages that a kind of numerical control machine slide rail accuracy detecting device of the invention, creative in bed piece two sides
Face is equipped with vertical datum plate, and symmetrically fixes a laser displacement sensor, laser under original state in steady for machine tool two sides
The collimation laser of displacement sensor is vertically projected on vertical datum plate.When lathe guide rail because big load or prolonged friction are led
When depth of parallelism variable quantity being caused to change, according to the variation of two laser displacement sensor output valves, can accurately it calculate
The precision of machine tool guideway, and the specific position that machine tool guideway deforms or wears can accurately be determined according to the display of host computer
It sets.
Specific embodiment
Further explanation is done to the present invention below.
A kind of numerical control machine slide rail accuracy detecting device, steady for machine tool are slidably connected with machine tool guideway, numerically-controlled machine tool bed
Body two sides are equipped with vertical datum plate, and the two sides of steady for machine tool are respectively fixed with a laser displacement sensor, two laser
Displacement sensor is symmetrical arranged about steady for machine tool.The vertical benchmark of collimation laser exit end face of laser displacement sensor
Plate, the output end of two laser displacement sensors are connected to host computer, and host computer is according to the output of the laser displacement sensor
Signal calculates lathe guide rail parallelism variable quantity.
Further, host computer includes display module and alarm modules, and display module is for showing that machine tool guideway is parallel
Degree variation magnitude, when machine tool guideway depth of parallelism variable quantity is greater than preset value, the alarm modules are used to send a warning, and
And the specific location that steady for machine tool position, that is, machine tool guideway deforms or wears at this time.
