Abstract
The utility model relates to a milling cutter depth adjusting mechanism, which includes a main shaft motor, a main shaft and a milling cutter, wherein the main shaft motor is fixedly installed on the main shaft; the milling cutter is installed at a cutter clamp fixedly installed at the lower end of the main shaft; a presser foot support frame is fixedly installed at the lower part of the main shaft motor; a presser foot is installed at the lower end of the presser foot support frame in a sliding manner through a presser foot height adjustment motor; and the milling cutter extends out of a lower plane surface of the presser foot from a cutting feed through hole formed in the corresponding position of the middle of the presser foot. Through adopting the milling cutter depth adjusting mechanism, reversion zero of the milling cutter position can be automatically realized with low cost through the simple method (presser foot), the milling depth can be controlled through software, and the milling cutter depth adjusting mechanism can obtain an favorable processing effect particularly to uneven or warped processing material.
Description
Technical field
The utility model belongs to the milling cutter degree of depth adjusting device of circuit board engraving machine, especially a kind of milling cutter depth adjustment mechanism.
Background technology
Current; The milling cutter working depth of circuit board engraving machine is to lean on the Z axle to move fixing distance to realize; Work in-process milling cutter depth of cut adjustment is difficulty comparatively, especially for the finished surface out-of-flatness or there is the rapidoprint of warpage will cause the inconsistent problem of milling depth, influences machining accuracy.
Summary of the invention
The purpose of the utility model is to overcome the weak point of prior art, and a kind of milling cutter depth adjustment mechanism of scientific and reasonable, simple in structure, conveniently adjusted milling depth is provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of milling cutter depth adjustment mechanism; Comprise spindle motor, main shaft and milling cutter; Spindle motor is packed on the main shaft, and milling cutter is packed in the main shaft lower end through cutter chuck, it is characterized in that: said spindle motor outer lower portion is fixed with the presser feet bracing frame; This presser feet bracing frame lower end is through the presser feet height adjustment motor presser feet that is slidingly installed, and the feed through hole that milling cutter is made by presser feet middle part correspondence position stretches out the presser feet lower plane.
And ad-hoc location is equipped with datum level on the corresponding board of main shaft.
The advantage and the good effect of the utility model are:
1, this milling cutter depth adjustment mechanism, the spindle motor bottom is fixed with the presser feet bracing frame, and this presser feet bracing frame lower end is through the presser feet height adjustment motor presser feet that is slidingly installed; This presser feet middle part milling cutter correspondence position is shaped on the feed through hole, and the feed through hole that milling cutter is made by presser feet middle part correspondence position stretches out the presser feet lower plane, during use; The degree of depth by system's control milling; Regulate the presser feet height, thereby regulate the length that milling cutter stretches out presser feet, accurately control the degree of depth of milling.
2, ad-hoc location is equipped with datum level on the corresponding board of the main shaft of this milling cutter depth adjustment mechanism, can adjust cutter and presser feet and get back to the relative zero position, accurately controls milling depth.
3, the utility model is realized milling cutter position self-zeroing at low cost with simple method (presser feet), and the control of milling depth available software particularly is directed against out-of-flatness or the warpage rapidoprint is arranged, and can obtain good processing effect.
Description of drawings
Fig. 1 is the utility model structural front view.
The specific embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of milling cutter depth adjustment mechanism comprises spindle motor 1, cutter chuck 2 and milling cutter 5, and spindle motor is packed on the main shaft; And can be by the distance of former engraving machine Z axle control up-down setting; Milling cutter is packed in the main shaft lower end through cutter chuck, and its innovative point is: said spindle motor outer lower portion is fixed with presser feet bracing frame 3, and this presser feet bracing frame is through presser feet height adjustment motor 7 presser feet 4 that is slidingly installed; Presser feet can be moved up and down by presser feet height adjustment driven by motor; The length adjustment of milling cutter being exposed presser feet is processed rapidoprint 6 to required, and ad-hoc location is equipped with datum level on the corresponding board of main shaft; Can adjust cutter and presser feet and get back to the relative zero position, accurately control milling depth.
The concrete operation principle of the utility model is:
Behind the main shaft gripping milling cutter, the presser feet motor is got back to its zero-bit.Main axle moving is to an ad-hoc location of board; The Z axle is being with spindle motor to descend, the presser feet bottom surface during apart from the datum level certain distance (point of a knife can not knock datum level before guaranteeing release clamp) unclamp the main axle cutter chuck, make milling cutter comply with himself gravity and glide; Contact datum level until point of a knife; Continue to move the Z axle then and main shaft is moved down up to presser feet be pressed onto datum level, clamp-on tool chuck then, this moment, point of a knife just flushed with the presser feet bottom surface.As relative zero, according to the degree of depth of Milling Process, move up with respect to main shaft and cutter with the software control presser feet again, make cutter stretch out presser feet bottom surface certain distance, this distance is exactly the degree of depth of cutter milling.
Claims (2)
1. milling cutter depth adjustment mechanism; Comprise spindle motor, main shaft and milling cutter; Spindle motor is packed on the main shaft, and milling cutter is packed in the main shaft lower end through cutter chuck, it is characterized in that: said spindle motor outer lower portion is fixed with the presser feet bracing frame; This presser feet bracing frame lower end is through the presser feet height adjustment motor presser feet that is slidingly installed, and the feed through hole that milling cutter is made by presser feet middle part correspondence position stretches out the presser feet lower plane.
2. milling cutter depth adjustment mechanism according to claim 1 is characterized in that: on the corresponding board of main shaft, a datum level is installed.
