The specific embodiment

As Fig. 1, 5, shown in 6, a kind of lathe spindle rotating governor motion, comprise with the hexagonal polished rod 30 of lathe and form the hexagonal axle sleeve 31 being slidably matched, handle 40 is fixedly connected with hexagonal axle sleeve 31, hexagonal axle sleeve 31 is arranged on the slip crate 20 of lathe and is rotationally connected with slip crate 20, described hexagonal polished rod 30 is rotationally connected with the bed body 10 of lathe, described hexagonal polished rod 30 is provided with the cam 32 being coaxially fixedly connected with it, on the bed body 10 of lathe, be provided with two microswitches 11 with cam 32 corresponding positions, two microswitches 11 respectively with lathe just, circuit for reversing is connected.When pulling handle 40, handle 40 drives hexagonal polished rod 30 to rotate and then is with moving cam 32 to rotate, the protuberance of cam 32 presses microswitch 11 just can control the rotating of main shaft, handle 40 is hinged by hexagonal axle sleeve 31 and slip crate 20 in addition, therefore handle 40 can slide together along with slip crate 20, like this since more convenient operating personnel control.

As Fig. 2, shown in 5, the outline of hexagonal axle sleeve 31 is cylindrical, described cylindrical body is provided with the endoporus that connects whole body, the cross sectional shape of described endoporus is the axis of regular hexagon and endoporus and the axis conllinear of cylindrical body, hexagonal axle sleeve 31 is provided with handle set 41 and bearing 21, described handle set 41 and bearing 21 comprise the connecting portion of the radial direction extension of He Yan socket part, canular socket part, the socket part of described handle set 41 is set on the periphery of hexagonal axle sleeve 31 and by the fastening nail 416 arranging on this socket part sidewall handle set 41 and hexagonal axle sleeve 31 is fixed together, the socket part of described bearing 21 is set on the periphery of hexagonal axle sleeve 31 and with it and forms and be rotatably assorted, described handle 40 is arranged on the connecting portion of handle set 41, the connecting portion of described bearing 21 is fixedly connected with slip crate 20.The effect of handle set 41 is to connect hexagonal axle sleeve 31 handles 40, and the effect of support 21 is to make handle 40 and slip crate 20 hinged, serves as jointed shaft with hexagonal axle sleeve 31 simultaneously.

As Fig. 3, shown in 4, a side relative with bearing on handle set 41 is provided with bar-shaped trough 414, described bar-shaped trough 414 extends to the end of handle set 41 connecting portions and the increase gradually in the direction of the degree of depth of bar-shaped trough 414 from the inwall of handle set 41 socket parts, a side end face relative with handle set 41, the socket part of described bearing 21 is provided with T-slot 211 and the wider place of T-shaped groove 211 is positioned at notch, described bar-shaped trough 414 and T-slot 211 are all along the radial direction setting of hexagonal axle sleeve 31, described handle 40 is between bar-shaped trough 414 and T-slot 211, the cell body axis interior and this jointed shaft that described handle 40 is hinged on one end that bar-shaped trough 414 degree of depth are larger is vertical with the axis of hexagonal axle sleeve 31, between one end that described handle 40 overhangs to hexagonal axle sleeve 31 and the bottom land of bar-shaped trough 414, be provided with Compress Spring 42.Normality lower compression spring 42 meeting handles 40 are pressed against the bottom of T-slot 211, now the cell wall at T-slot 211 narrower places, bottom can limit the swing of handle 40 on hexagonal axle sleeve 31 circumferencial directions, that is to say that handle set 41 and bearing 21 are blocked and can not relatively rotate by handle 40, when handle 40 is positioned at this station, cam 32 does not contact with microswitch 11, main shaft is in stop state, when handle 40 is during along axially the pulling of hexagonal axle sleeve 31, due to lever principle, Compress Spring 42 can be compressed, handle 40 also can exit the narrower cell body of T-slot 211 and enter in wider region, now again handle 40 is pulled along the circumferencial direction of hexagonal axle sleeve 31, handle 40 just can drive hexagonal axle sleeve 31 to rotate and then drive hexagonal polished rod 30 to rotate, then put down handle 40, Compress Spring 42 will be pressed against handle on the stair-stepping step of T-slot 211, when handle 40 is positioned at this station, cam 32 is just pressed on forward or reverse microswitch, main shaft forward or reverse.

As shown in Figure 5, a relative side end face, the socket part of the socket part of bearing 21 and handle set 41 is bonded to each other, the socket part end face of handle set 41 is provided with through hole 415, in described through hole 415, be provided with spring 411, in through hole 415, a side relative with bearing 21 is provided with steel ball 412, the opposing side of through hole 415 and bearing 21 is provided with screw 413, a side end face relative with handle set 41, the socket part of described bearing 21 is provided with the pit 212 of three tapers, described three pits 212 equate and equate to the distance in hexagonal axle sleeve 31 axle center with through hole 415 to the distance in the axle center of hexagonal axle sleeve 31.The position of three pyramidal pits 212 as shown in Figure 4, when handle 40 is positioned at initial station, in pit 212 in the middle of steel ball 412 on handle set 41 is crushed on, pull the rear steel ball 412 of handle 40 and can skip in the pit 212 on side, the effect of this structure is exactly mainly to prevent that in order to allow handle 40 can be subject to certain restraining force when each station handle 40 from beating between each station.

As shown in Figure 6, hexagonal polished rod 30 is provided with the circumferential interval of the protuberance of 32, two cams 32 of two cams and arranges, two cams 32 position is in the axial direction corresponding with the position of two microswitches 11 of controlling forward and backward circuit respectively.
