Description
Technical field
The utility model relates to the numerical control machine tool technique field, is specifically related to the device of Digit Control Machine Tool on-line measurement machined surface flatness.
Background technology
Existing Digit Control Machine Tool can be finished the processing parts overall process automatically, but the function that lacks on-line measurement, particularly when processing bigger plane, because workpiece can produce distortion in process, the requirement so the precision of processing back plane not necessarily meets the demands, if workpiece is removed the precision that just can know its plane after the measurement, that not only bothers but also lose time.If can be after processing its plane precision of on-line measurement, just can save time, increase work efficiency.
Utility model
The problem that the utility model solves provides a kind of device of Digit Control Machine Tool on-line measurement machined surface flatness simple in structure.
For solving the problems of the technologies described above, the technical scheme that the utility model is realized is:
A kind of device of Digit Control Machine Tool on-line measurement machined surface flatness, comprise on the holder that is installed on the lathe Z axle slide plate, the holder driving mechanism is installed that one is connected on the driving mechanism with contact that computer telecommunication number is connected and is moved up and down by drive mechanism.
As improvement of the technical scheme, described driving mechanism is a cylinder, and contact is connected on the piston rod of cylinder by guide pillar.Described guide pillar is the round steel barred body, and the guide pillar two ends have internal thread, and guide pillar one end is connected with cylinder piston rod by screw thread, and the guide pillar other end is connected with contact by screw thread.The outside of described guide pillar also is with the direction of motion oiliness bearing of a restriction guide pillar.
The utility model has following remarkable result compared to existing technology:
But the device of the machined surface flatness of on-line measurement Digit Control Machine Tool processing work provided by the utility model, it is installed on the Z axle of Digit Control Machine Tool and along with Z moves up and down, touch the workpiece machined surface and add man-hour when the Z axle moves down, the contact of measuring the device of machined surface flatness also touches machined surface, contact sends the position signalling of machined surface to computer, and is calculated the flatness of this measurement plane automatically by computer.This measurement mechanism is installed on the Z axle of Digit Control Machine Tool, can measure the plane precision of workpiece in Digit Control Machine Tool processing, not only can save time, and improve operating efficiency.
Description of drawings
Accompanying drawing 1 is that the utility model is assemblied in the structural representation on the lathe Z axle.
Accompanying drawing 2 is cross section structure schematic diagrames of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.Referring to accompanying drawing 1,
A kind of device of Digit Control Machine Tool on-line measurement machined surface flatness, comprise on the holder 1 that is installed on lathe Z axle 5 slide plates, the holder driving mechanism is installed that one is connected on the driving mechanism with contact that computer telecommunication number is connected and is moved up and down by drive mechanism.Driving mechanism adopt motor and with the transmission mechanism of electric drilling match, can also adopt prior art means such as cylinder class transmission mechanism.Driving mechanism is a cylinder 2 in the present embodiment, connects guide pillar 3 on the piston rod of cylinder.See Fig. 2, guide pillar is the round steel bar of a diameter 12mm length 100mm, and there is internal thread at its two ends, above the screw thread of an end be connected with cylinder piston rod 21, below the screw thread of an end be connected with contact 4, cylinder piston rod, guide pillar, three parts of contact fuse like this.Acting between cylinder rod and the contact of guide pillar works the effect of connection, play the guiding role when contact need move up and down simultaneously.Also be with an oiliness bearing 31 in the outside of guide pillar, can limit the direction of motion of guide pillar.When contact need be done surveying work, cylinder piston rod 21 moved downward, and guide pillar 3, contact 4 and then move downward; when contact did not need to do surveying work, the cylinder rod piston moved upward, and drive guide pillar, contact move upward; contact just can not run into workpiece like this, plays a protective role.Contact can be a contact-making switch in the present embodiment, perhaps existing other contact contacts etc.Contact is electrically connected with computer, contacts machined surface as contact and can be transferred to computer to signal.Should be noted that during concrete the installation when the contact position that the piston rod movement of cylinder is installed to the lower dead center piston rod bar and need be positioned on the same horizontal plane with Z axle lower end position 6, contact machined surface and go into operation when doing when lathe Z is coupling guaranteeing, contact can touch machined surface.When not needing contact to do surveying work, contact can be protected contact like this along with guide pillar rises to top dead center position under the action of cylinder, and the effect of guide pillar is to play the guiding role.
The use of the utility model measurement mechanism is specified in down: when measurement mechanism was not worked, the piston rod on the cylinder was positioned at top dead centre, and guide pillar that the cylinder upper piston rod connects and contact are away from machine tooling face; When measurement mechanism began to measure, the piston rod on the cylinder was pushed the contact on guide pillar and the guide pillar lower dead center of cylinder to,
Whole then Z axle begins to move down, and Z is coupling and contacts machined surface and begin to add man-hour, and contact 4 is also run into the machined surface that will measure and sent a signal to computer, and computer receives the signal of contact transmission and writes down the coordinate information of contact; Then Z axially goes up and rises, X, Y-axis move to next Working position, contact also transmits signal to the next position that touches to computer, repeats pre-set measurement point has all been surveyed so always, and last computer will calculate the flatness of this measurement plane automatically.
Originally be that utility model is installed in measurement mechanism on the Z axle of Digit Control Machine Tool, can in Digit Control Machine Tool processing, measure the plane precision of workpiece, not only can save time, and improve operating efficiency.
The foregoing description only is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the present utility model design, any conspicuous replacement all should fall within the protection domain of the present utility model.
