Description

Wheel hub measurement mechanism
Technical field
The utility model relates to hub size measurement mechanism, specifically, is the device center-hole diameter of wheel hub and hub height being carried out to on-line measurement.
Background technology
In order to measure wheel hub center-hole diameter, conventional measurement structure uses elastic telescopic gauge head, and gauge head two ends slip in tested center pit, gauge head and center pit sliding friction during measurement, sliding friction can cause gauge head and measured workpiece contact point to wear and tear, and causes measuring accuracy to decline; Telescopic gauge head measurement range is little in addition, and measuring the larger wheel hub of diameter difference needs to change different flexible probes, and flexible probe also exists the factors such as job insecurity in addition, and needs manual calibration, uses inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of wheel hub can measuring different-diameter, and be that touch-type contacts between switch with workpiece during test, do not have sliding friction, the life-span is long, working stability, measures wheel hub measurement mechanism accurately.
Wheel hub measurement mechanism of the present utility model, frame is provided with the cross motor of transverse movement slide block and driving transverse movement slide block transverse shifting, longitudinal motor transverse movement slide block being provided with lengthwise movement slide block and driving lengthwise movement slide block to vertically move, lengthwise movement slide block is provided with the touch-type switch for stretching in hub centre hole, transverse movement slide block is provided with the horizontal raster chi for measuring transverse movement slide block transverse shifting distance, lengthwise movement slide block is provided with the longitudinal grating scale vertically moving distance for measuring lengthwise movement slide block.
The beneficial effects of the utility model: when measuring center-hole diameter, transverse slider moves, and touch-type switch moves.When touch-type switch contacts with center bore inner wall, cross motor stops action.With the position of now horizontal raster chi for benchmark, then cross motor oppositely movement, until touch-type switch contacts with center bore inner wall, records the positional value of now horizontal raster chi, completes the measurement of horizontal direction.In like manner complete the measurement of longitudinal direction.Like this, totally four point coordinate of horizontal direction and longitudinal direction can be recorded, so just can calculate the diameter of tested center pit.
Above-mentioned wheel hub measurement mechanism, cross motor drives transverse slider to move by nut screw mechanism; Longitudinal motor drives longitudinal sliding block to move by nut screw mechanism.
Above-mentioned wheel hub measurement mechanism, frame is also provided with vertical telescopic arm and drives the motor vertical driving vertical telescopic arm to move up and down, be provided with the touch-type switch that can contact with wheel hub upper surface in the lower end of vertical telescopic arm, it also comprises the vertical distance-measuring device for measuring vertical telescopic arm displacement.
Can measure hub height like this.During measurement, vertical telescopic arm moves up and down, and records vertical distance-measuring device position now, compare can learn hub height with reference value when the touch-type switch on vertical telescopic arm and wheel hub end contact.
Above-mentioned wheel hub measurement mechanism, vertical distance-measuring device is the vertical raster chi be arranged on vertical telescopic arm.
Above-mentioned wheel hub measurement mechanism, vertical distance-measuring device is the scrambler be connected with motor vertical.
In order to can automatically measure, above-mentioned wheel hub measurement mechanism, it comprises Programmable Logic Controller, and touch-type switch, cross motor, longitudinal motor, horizontal raster chi, longitudinal grating scale are all electrically connected with controller.
Accompanying drawing explanation

Fig. 2 is the schematic side view of wheel hub measurement mechanism.
Embodiment
See the aluminium alloy wheel hub measurement mechanism shown in Fig. 1,2, the support 2 of fixed support wheel hub 100 in frame 1.
Support arranges cross slide way, and transverse slider 3 slides along cross slide way, and horizontal leading screw 4 coordinates with transverse slider, and horizontal servomotor 5 is connected with horizontal leading screw.Horizontal servomotor action, drive horizontal screw turns, namely transverse slider moves along cross slide way.Horizontal raster chi 6 comprises scale grating and grating reading head two parts, and scale grating is fixed on transverse slider, and grating reading head is fixed in frame.
Transverse slider arranges longitudinal rail, longitudinal sliding block 13 slide along the longitudinal, longitudinal leadscrew 14 coordinates with longitudinal sliding block, and servo longitudinal motor 15 is connected with longitudinal leadscrew.Servo longitudinal motor action, drive longitudinal leadscrew rotate, longitudinal sliding block namely along the longitudinal guide rail move.Longitudinal grating scale 16 comprises scale grating and grating reading head two parts, and scale grating is fixed on longitudinal sliding block, and grating reading head is fixed on transverse slider.
Vertical columns on longitudinal sliding block 13, column is arranged the center pit measuring sonde 18 with touch-type switch stretched in hub centre hole.
Frame is also provided with vertical telescopic arm 7, and vertical telescopic arm 7 upper end is connected with tooth bar 8, and tooth bar 8 slides and arranges on upright guide rail, and gear coordinates with gear 9, and gear is fixed on the output shaft of vertical servo motor 10.Scrambler is connected with vertical servo motor output shaft.The lower end of vertical telescopic arm is provided with the upper level measuring sonde 19 with touch-type switch 11 that can contact with wheel hub upper surface.
Programmable Logic Controller is electrically connected with the grating reading head of scrambler, two touch-type switches, horizontal servomotor, servo longitudinal motor, vertical servo motor, horizontal raster chi, two grating scales respectively.
Above-mentioned touch-type switch can be machinery or electronic switch.
When measuring center hole is straight, first Programmable Logic Controller controls transverse direction or servo longitudinal motor removing center pit measuring sonde, whether the touch-type switch that Programmable Logic Controller detects in Mobility Center hole measurement probe is excited, after switch is excited, Programmable Logic Controller record excites the positional value of moment grating scale, and then control motor and move round about, equally, whether the switch in Programmable Logic Controller detection probe is excited, after switch is excited, Programmable Logic Controller record excites the positional value of moment grating scale; After completing this orientation measurement, Programmable Logic Controller and the motor action of axle vertical before, measure positional value by same procedure; Computer calculates tested centre hole side diameter according to the coordinate of measure 4 points.
When measuring upper surface height, Controlled by Programmable Controller vertical telescopic arm is close to wheel hub, whether the touch-type switch that Programmable Logic Controller detects in upper level measuring sonde is excited, after switch is excited, Programmable Logic Controller record excites the numerical value of moment scrambler, and Programmable Logic Controller calculates the height of wheel hub upper surface relative to pedestal upper end face according to measured value and reference value.
It is mobile that this patent uses motor automatically to control probe, uses grating scale, scrambler etc. as surveyors' staff, automatic calibration zero point, applied widely, without the need to changing parts when measuring the wheel hub of different-diameter; Pop one's head in be that touch-type contacts between workpiece, there is no sliding friction, therefore there is the features such as life-span length, working stability.
