Abstract
The invention relates to a high-precision translational working table of a hard-brittle material cutting machine, which is mainly used for cutting the quartz crystal material into sheet material. The high-precision translational working table comprises an upper supporting plate (8) and a lower supporting plate (12) which are matched via a slide rail pair of a sliding block, wherein, a driving motor is fixedly installed at one end of the lower supporting plate (12), the motor drives the upper supporting plate (8) to move horizontally by an accuracy leading screw (5), a grating measuring device (28) for measuring the amount of movement of the upper supporting plate is arranged at the side of the lower supporting plate (12), and a locking device for pressing the upper supporting plate towards the lower supporting plate is also arranged on the lower supporting plate. Since the grating measuring device is arranged at the side of the supporting plate, the stepping motor drives the accuracy leading screw to drive the upper supporting plate to finish horizontal movement, the microcomputer controller drives the piston rod of an air cylinder to press and lock the upper supporting plate, the upper supporting plate is not slightly shifted during the locking process, therefore, the cutting precision of the processed parts is ensured, the tuning fork conforming to the requirement of precision is cut out, and the yield rate is improved.
Description
Technical field
The invention belongs to mechanical field, relate to the translational worktable of hard and brittle cut-off machine, be specially adapted in the electronic component industry cutting quartz crystal materials.
Background technology
The hard brittle material slicer is followed by the finer wire straight reciprocating motion of many parallel pile warp rollers and is contained sand oil and constitute cutting blade, the hard fragility bar that is packed on the translational worktable needs to move to carry out the cutting of diverse location relative to finer wire, can be applicable to quartz crystal materials is cut into thin slice.Existing a kind of translational worktable adopts the motor leading screw to drive, and with laser interferometer as the measurement feedback element, but the locking mechanism complexity causes bigger Abel's error easily with laser interferometer.Because the used quartz crystal size of electronic component is less; cutting action such as 2 * 6mm tuning fork sheet (32.768KHZ specification) is: after cutting the blind groove of dark 3.13 ± 0.02mm, wide a 0.2 ± 0.01mm earlier; shut down; workpiece is returned to the original preceding position of not cutting; table translation 1.206 ± 0.001mm is apart from back locking; start is cutting workpiece again; make wide 0.4 ± 0.005mm (the steel wire diameter ф 0.167mm that respectively keeps of both sides arm of tuning fork; use GC1200# diamond dust, the sand seam is estimated 0.027-0.03mm).Cut out above-mentioned qualified products,, require worktable displacement must not exceed 0.001mm through table latch being produced drift with the vibrations that prevent machine to workbench after the translation.Present traditional translational worktable product, when table translation all is to use the amesdial manual measurement during to desired size, when reaching desired location again by stalloy with manual housing screw locking positioning.Because stalloy when use screw in compression, must allow the screw rotation compress steel disc, make workbench about planker fuse, allow be cut part and be securely fixed on the required accurate position.Because by screw in compression, the rotation that must on steel disc, rub of the seal face of screw, it is axially micro-mobile that steel disc is produced, and causes the precision that is cut part to be difficult to be guaranteed.What Chinese patent 200720074277.4 " table device of multi-line cutting machine " was introduced also is the screw lock structure, so the qualification rate of commercial translational worktable cutting products is lower, can't reach the required precision of cutting quartz tuning-fork, reduce relatively difficulty of tuning fork product cost.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical problem, provide a kind of simple in structure, can be conveniently carry out the high precision translational worktable of the hard and brittle cut-off machine that accurate displacement adjusts to workbench.
The high precision translational worktable of a kind of hard and brittle cut-off machine of the present invention, comprise by the last planker of the secondary fit structure of slide block slide rail, following planker, one side of following planker installs drive motors, motor drives by precision lead screw and goes up the planker translation, it is characterized in that the side of planker is equipped with the grating measuring device that the planker amount of movement is gone up in measurement down, following planker also is equipped with the locking device that the downward planker of last planker is pressed down.
Described drive motors is a stepper motor, and step motor shaft is connected with precision lead screw by shaft coupling.
Install nut with the precision lead screw threaded engagement at last planker lower surface, the measuring-signal of grating measuring device is linked to microcomputer controller, the rotation of microcomputer controller control step motor, planker translation in the driving.
The structure of described locking device is: the cylinder by microcomputer controller control is housed in following planker bottom surface, its piston rod upwards with will go up the pressing plate that planker presses down and be connected.
Have the fenestra that there is step both sides at last planker, pressing plate is positioned at this fenestra and forces on the step.
Described fenestra is made rectangle, and corresponding pressing plate is also made rectangle, and the width of pressing plate is less than the width of fenestra.
Described and the nut precision lead screw threaded engagement is fixed in the planker bottom surface by four screws.
Workbench is loaded on the inner top surface of cabinet, runs through the material platform that backing plate will be positioned at end face on the cabinet with screw and fixedlys connected with last planker, and backing plate has the elongated slot that moves for screw, its week along and the cabinet end face between seal.
The present invention is equipped with grating measuring device at the side of planker, and displacement data signal accurately is presented on the touch-screen by microcomputer controller, set the translation distance parameter by the microcomputer controller input, and go up planker by the drive of stepper motor driving precision lead screw and finish translation, worktable displacement must not exceed 0.001mm when requiring locking, microcomputer controller promptly drives cylinder piston rod and will go up planker and press down locking, so that carry out the material sectioning, because cylinder piston rod only produces vertical, horizontal little the moving of planker in locking process, can not producing, guaranteed the cutting accuracy of part to be processed, cut out the tuning fork that meets fully or surpass the product drawing required precision, yields improves.
