Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, a kind of Digit Control Machine Tool workpiece measuring device of the utility model, be installed on the stepping of Digit Control Machine Tool or the screw mandrel 2 of servomotor 1 control, comprise the travel switch 4 that the slide unit 3 of installation on screw mandrel 2, slide unit are installed, and the location-plate 5 that distance travel switch fixed range is installed; Travel switch 4 is electrically connected the control unit (not shown) of Digit Control Machine Tool, and control unit is closed down motor 1 when travel switch 4 is triggered by workpiece 6 and drawn workpiece size according to preset program.Travel switch 4 can select contact travel switch or Contactless stroke switch, and be preferably contact travel switch, travel switch 4 can directly be installed on slide unit 3, and preferably, travel switch 4 is installed on slide unit by a switch bracket 7.
The motor shaft of servo of the present utility model or stepper motor is connected with screw mandrel, and screw mandrel coordinates with slide unit.Electric machine rotation, then screw mandrel rotates; Screw mandrel rotates, then drive slide unit to advance or retreat.Slide unit fixedly mounts a switch bracket, and switch bracket end fixed installation travel switch, the contact of travel switch is towards workpiece direction.Before measurement, slide unit, by screw mandrel, is retracted into zero point, as shown in A point in Fig. 1 by motor.It should be pointed out that slide unit is returned to zero point by motor is the most conventional and requisite action in Digit Control Machine Tool, can ensure that each all parking position accuracies of slide unit are to zero point, its reliability ordinary authentication.Location-plate of the present utility model is fixedly mounted on the position vertical with screw mandrel axis direction, and in preferred embodiment, location-plate 5 is with screw mandrel 2 for noncontact is installed, and namely installation site departs from slide unit and screw mandrel, does not change by slide unit motion.Therefore, the anchor point (in Fig. 1 B point) of location-plate and the distance L1 of above-mentioned A point are fixed values.This value can be obtained by conventional measuring methods such as gages.Because travel switch is also be fixedly mounted on slide unit itself, both are rigidly connected, and therefore, slide unit zero point (in Fig. 1 A point) is also changeless with the distance L2 of travel switch trigger point (in Fig. 1 C point), also obtains by general measuring method.Continue to participate in Fig. 1, L1-L2=L3.L3 is slide unit when being in dead-center position, and the distance of travel switch trigger point and location-plate anchor point, because L1, L2 are fixed value, therefore L3 is also a fixed value.
Measuring process of the present utility model is as follows:
A) workpiece for measurement is positioned between location-plate and travel switch, is wherein close to the gulde edge of location-plate.
B) servo or stepper motor start, and drive slide unit to advance to location-plate direction from zero point (A point) by screw mandrel.Now, the travel switch on slide unit is also in advanced in unison.
C) travel switch is constantly near workpiece, and finally make the contact of travel switch be pressed, its contact is triggered in a flash at this.Trigger position is see Fig. 2.
D) travel switch is in a flash breaker-triggered, and travel switch sends a signal connected to control unit, and control unit, by programme-control, makes motor decommission immediately and records the number of pulses now sent altogether.By preset program, the umber of pulse that control unit closes stopping time generation according to motor calculates slide unit stroke, and the workpiece size that converts.Concrete principle is by the electric machine main shaft revolution corresponding to number of pulses, then by the conversion of screw lead, can calculate slide unit displacement, in Fig. 1 shown in X.And calculate workpiece and be of a size of: Y=L3-X.That is, Y value is measurement result.
E) measure end, control unit controls slide unit and revert to zero point, to carry out measurement next time.
It is important to note that travel switch is fragile electrical equipment, for better protecting travel switch, the utility model provides a kind of preferred embodiment, is arranged with protective cover 8 outside travel switch, and protective cover is installed on switch bracket 7.More preferably, the contact place of travel switch is provided with the rigid rod 9 extended to workpiece direction.See Fig. 3, the contactor end of travel switch connects a rigid rod, and rigid rod is movably arranged on switch bracket, presses travel switch contact, realize above-mentioned measurement function equally by rigid rod one end and absorption surface, the other end.Be convenient under travel switch is hidden in protective cover like this, avoid travel switch to be exposed to outer and directly and absorption surface, more attractive in appearance and durable.In order to protect travel switch better, in another kind of preferred embodiment of the present utility model, switch bracket shrinks in slide unit upper surface when non-measured state.Switch bracket and stretch shrink and stretch out, the modes such as gas transmission, hydraulic drive or electric transmission can be selected to be movably installed in slide unit, not to be particularly limited herein.Certainly, gas transmission, hydraulic pressure or electric transmission make switch bracket stretch out on screw mandrel axis direction easily or return; When stretching out, by adjustment support installing position or increase electromechanical stop, the contact of having stretched out rear travel switch is made to be positioned at travel switch trigger point C point all the time; When returning, support all shrinks in slide unit upper surface together with travel switch, and when avoiding non-measured, support stretches out and to bring inconvenience impact on machine tooling, and also imitative only other operation damages travel switch.It is important to note that these two kinds of embodiments are not as to independent restriction of the present utility model, as being provided with retractor device and protective cover etc. simultaneously, can not think beyond protection domain of the present utility model.
More preferably in embodiment, location-plate 5 position is adjustable, to make having multiple fixed range between travel switch and location-plate.Location-plate can be set to form that can be movable along left and right on screw mandrel axis direction.The position of adjustment location-plate also, after making it fixing, can obtain above-mentioned L1 size by the measuring method of routine equally, measuring principle and process consistent with above-mentioned.The benefit of adjustment location-plate fixed position is, for the workpiece to vary in size batch, the distance of slide unit movement can be made to adjust comparatively to proper, to significantly improve measurement efficiency.If the very large workpiece of size, then location-plate can be moved right, make it can be measured, if the workpiece that size is smaller, then location-plate can be moved to left, to reduce the distance of slide unit movement, improve and measure efficiency.
The utility model is used for Digit Control Machine Tool, or other has the equipment to servo or stepper motor, additionally need only increase a travel switch and location-plate, can realize the measurement to workpiece.The reliability of servo or stepper motor and travel switch, ensure that the accurate and permanent service life of measurement result.In addition, relative to other measuring instrument of use, the art of this patent is more easily installed, is more saved space, and avoids loaded down with trivial details circuit to arrange.There is the measurement function to workpiece, for the following process of equipment provides dimensional parameters, maybe can carry out dimension control to converted products, enrich function and the practicality of equipment.
