The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5 and Fig. 6, in the present embodiment, should be for the profiling head of lathe, comprise tool fitting 3 and pattern contact mount pad 4, cutter 31 is located on tool fitting 3, pattern contact 41 is located on pattern contact mount pad 4, this profiling head also comprises a firm banking 1, mobile base 2 and cutter returning device, mobile base consists of aluminium alloy, tool fitting 3 and pattern contact mount pad 4 are fixed on this mobile base along mobile base 2 length directions, mobile base 2 one ends are located on firm banking 1 by rotating shaft 5, the axis of rotating shaft 5 is vertical state, rotating shaft 5 is located on firm banking 1 by taper sliding bearing 8, due to this taper sliding bearing 8 each taper mandrel 81 up and down, can be adjusted to by the bolt of tapered core shaft end the revolution gap that makes rotating shaft is zero, assurance is without overlay error, improve machining accuracy.Be provided with spring 6 between firm banking 1 and mobile base 2, spring 6 one ends are fixed on firm banking, the other end is the state of overhanging, by this spring 6, cutter and pattern contact are resisted against on workpiece He on pattern and carry out copying, the cutter returning device comprises cylinder (not shown in FIG.) and the second spring 72, cylinder and the second spring 72 are located on firm banking, and cylinder is installed on a flange 71 on firm banking, and while needing work, the piston rod of cylinder stretches out from the hole of flange 71 central authorities.
Be provided with a cantilever design 11 in firm banking 1 bottom, this hanging wall construction and firm banking are perpendicular, be provided with a bull stick 12 by bearing pin 13 on this cantilever design, spring 6 between firm banking and mobile base, rely on the elastic force of spring 6 that cutter and pattern contact are resisted against on workpiece and pattern, the piston rod of cylinder and bull stick 12 align near an end of mobile base rotating shaft 5, bull stick 12 other ends are provided with a vertical little axle 14, mobile base bottom 2 grooves 21 that are provided with along its length, little axle 14 stretches in this groove 21, the diameter of little axle 14 is less than the width of this groove 21.These the second spring 72 1 ends are fixed on cantilever 11, and the other end is the state of overhanging, and this second spring 72 is positioned at the end of bull stick near the mobile base rotating shaft, that is, the second spring 72 lays respectively at the both sides of bull stick 12 near rotating shaft 5 one ends with cylinder.Be provided with chute along its length at the mobile base upper side, tool fitting 3 and pattern contact mount pad 4 are located on this chute by bolt, the distance of pattern contact mount pad and rotating shaft is greater than the distance of tool fitting and rotating shaft, when needs regulate the two and rotating shaft apart from the time, can unclamp bolt, be regulated along chute.Because the distance of pattern contact and rotating shaft is greater than the distance of cutter and rotating shaft, so the movement travel of the movement travel of pattern contact and cutter is proportional, and the movement travel of pattern contact is greater than the movement travel of cutter.When cylinder piston rod stretches out from the medium pore of flange 71, because piston rod aligns with bull stick one end, piston rod promotes bull stick 12 and rotates, and mobile base 2 is rotated, and cutter is separated with pattern with workpiece with the pattern contact; When cylinder piston rod is retracted, under the second spring 72 effects, mobile base 2 is repositioned to and the firm banking parastate, under the effect of spring 6, cutter is pushed against and contacts with pattern with workpiece with the pattern contact, be convenient to next part processing.
As shown in Figure 6, during use, the present invention is fixed in the slide carriage of lathe for the profiling head of lathe by firm banking, pattern 102 and workpiece 103 are connected on main tapping by gripping mechanism, and with main shaft 101 coaxial lines, workpiece is held out against by tailstock 104, under spring 6 effects, pattern contact 41 is abutted together with pattern 102, when driving in pattern and workpiece rotary course, main shaft just by lathe tool 31, cut the outline of workpiece like this, because tool fitting and pattern contact mount pad are arranged in same chute, distance between pattern contact mount pad and bearing is greater than the distance of tool fitting and bearing, therefore the workpiece outline cut is similar to the outline of pattern, and the ratio of having done is dwindled, this proportionality coefficient equals the ratio of distance L 1 between distance L 2 between pattern contact mount pad and bearing and tool fitting and bearing.As can be seen here, adjust by chute relative position that tool fitting and pattern touch mount pad and just can obtain the workpiece with pattern appearance similar, proportional zoom, regulate very convenient; Embedded ball rolling element bearing guide rail and mobile base in arc guide rail, the high-frequency reciprocating motion that the ball rolling element is quick on the draw and can adapts to knife rest, without motion delay.
Except such scheme, the tool fitting in the present invention and pattern contact mount pad also can be installed in two chutes on mobile base; The adjusting device of lathe tool extension elongation also can not adopt screw-rod structure, such as adopting gear & rack structure or worm gear structure, can realize that equally the fine adjustments lathe tool stretches out long function; Arc guide rail between mobile base and firm banking, it is transversal can be rectangle, can be also I-shaped; The return part of cutter returning device also can adopt a cylinder, same, and the actuator of cutter return device also can drive the nut-screw structure by a slowspeed machine and form.
