Detailed description of the invention
nullThis utility model numerical control borer facing head depth-feed mechanism of the present utility model be embodied as such as Fig. 1、Fig. 2、Fig. 3、Shown in Fig. 4，It includes the electric machine main shaft 2 being arranged in main spindle box 1、It is arranged on the rotary body 3 of electric machine main shaft 2 front end、The tool rest 12 being slidably mounted on rotary body 3 along electric machine main shaft 2 radially-directed、It is divided into first planet reduction box 4 and second planetary reduction box 5 of electric machine main shaft 2 rear and front end、The central shaft 6 being coaxially arranged in electric machine main shaft and the gear-box 7 being located at main spindle box 1 rear portion and servomotor 8，Wherein，First planet reduction box 4 and the casing of the second planetary reduction box 5 and output shaft all rotate coaxially assembling with electric machine main shaft 2，First planet reduction box 4 is installed in the front end spindle nose of electric machine main shaft 2，The casing of this first planet reduction box 4 is coaxially connected with rotary body 3，Its output shaft is stretched into forward in rotary body 3 and is in transmission connection with tool rest 12 by pinion and rack；The front end of central shaft 6 is coaxially connected with the casing of first planet reduction box 4, the rear end of central shaft 6 is connected by the output shaft coaxial transmission of shaft coupling and the second planetary reduction box 5, meanwhile, the casing of the second planetary reduction box 5 is connected with the rear-end transmission of electric machine main shaft 2 by the travelling gear in gear-box 7；Servomotor 8 is arranged on the protection shell of the second planetary reduction box 5, and the output shaft of this servomotor 8 passes the hole offered on protection shell and is connected with the casing coaxial transmission of the second planetary reduction box 5.In the present embodiment, gear-box 7 includes the casing being fixed on main spindle box 1 rear portion, be provided with in casing be coaxially installed on electric machine main shaft 2 rear end the first gear 71, coaxially be fixed on the second gear 72 on the second planetary reduction box 5 casing and simultaneously with the first gear 71 and change-speed gearing 73 of the second gear 72 engaged transmission, the rotating ratio between the first gear 71 and the second gear 72 is 1:1.5.
During work, on the one hand the power of electric machine main shaft 2 be rotated body 3 and rotate, and the power of electric machine main shaft 2 is transferred to the output shaft of the second planetary reduction box 5 by rotary body 3 successively through the casing of first planet reduction box 4, central shaft 6, on the other hand, the power of electric machine main shaft 2 passes to the gear-box 7 at rear portion, and the first gear 71 in gear-box 7 drives the casing of the second planetary reduction box 5 to rotate through change-speed gearing 73 and the second gear 72 successively and makes the casing rotating speed of the second planetary reduction box 5 increase by 1.5 times.Comprehensive above drive mechanism, the casing rotating speed of the second planetary reducer 8 is equal to 1.5 times of its output shaft rotating speed, and rotation direction is consistent.In the present embodiment, the speed reducing ratio of the second planetary reducer 8 is 1:3, i.e. drives sun round three to enclose when speed reducer output shaft, and planet carrier output shaft turns around, and is equivalent to each planetary gear and turns around on external toothing.Opposite direction, if external toothing rotates 1.5 circles while of making output shaft turn around, power shaft is without any rotation.So when casing rotating speed is its output shaft rotating speed 1.5 times of the second planetary reducer 8, the actual speed of the second planetary reducer 8 casing is zero.I.e. when servomotor 9 does not works, and only electric machine main shaft 2 works, only realize the spinning movement of rotary body.When electric machine main shaft 2 does not works, and servomotor 9 works, power is delivered to the output shaft of first planet reduction box 4, drives tool rest 12 to move by pinion and rack.
In the present embodiment, the left and right guide slide offering two parallel interval settings symmetrical in rotary body 2, in left and right two guide slides, it is individually directed slideway left slide carriage 9 and right slide carriage 10 are installed, wherein, left slide carriage 9 is fixing with tool rest 12 to be connected, for driving tool rest 12 moving radially along electric machine main shaft 2；Right slide carriage 10 is guided by the slide block 13 that guide rail 14 fixed thereon and tool rest 12 bottom surface are fixing and is slidably matched, and supports for providing tool rest 12, it is ensured that the stability that tool rest 12 moves.Left slide carriage 9 and right slide carriage 10 are in transmission connection by the output shaft synchronous of pinion and rack with first planet reduction box 4 respectively, run so that left slide carriage 9 and right slide carriage 10 synchronize to do reverse linear when mobile, such that it is able to the dynamic balancing improved in rotary body 3 work process, prevent cutter point of a knife stress at work excessive and produce vibration, improve the job stability of rotary body 3 further.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
