Double tool rest vertical lathe knife rest anticollision device, collision-prevention device
Technical field
The present invention relates to a kind of protector of vertical lathe, specifically refer to a kind of double tool rest vertical lathe knife rest anticollision device, collision-prevention device.
Background technology
In double tool rest vertical lathe, left and right knife rest is horizontal feed motion on same beam guideway.When processing minor diameter part, left and right knife rest is simultaneously to the feed motion of workpiece centre direction, and when diameter of part is less than the minimum approach distance between two knife rests, left and right knife rest can bump, and causes device damage.
Summary of the invention
For preventing that double tool rest vertical lathe is when processing minor diameter part, the technical problem that left and right knife rest likely bumps, the invention provides a kind of double tool rest vertical lathe knife rest anticollision device, collision-prevention device.
The technical solution used in the present invention is: double tool rest vertical lathe knife rest anticollision device, collision-prevention device, it is included in the left socle that is fixed on left knife rest inner side and the right support that is fixed on right knife rest inner side, left and right support is positioned on same level line, it is characterized in that: the front end at left knife rest is provided with impact head, at the front end of right support, fix a flange and support dish, one screw rod parallel with right support supports dish through flange, screw front end is fixed with shock ring flange, at shock ring flange and flange, on the screw rod body between dish, be set with resilient sleeve, the described flange that is positioned at supports suit induction cover on the screw rod body of back-end disk, the end of screw rod body is provided with rubber sleeve, on the right support position corresponding with rubber sleeve, be provided with inductive switch, inductive switch is connected with lathe servo-drive system.
Described induction cover is metallic sheath, and described inductive switch is approach switch.
This double tool rest vertical lathe knife rest protector is taked after said structure, when the distance between the knife rest of left and right approaches its minimum approach distance, the support being arranged on the knife rest of left and right bumps, after screw rod on right support, move, induction cover triggers inductive switch and sends signal, and signal feedback is to servo-drive system, and the knife rest of servo system control moves horizontally motor and quits work, left and right knife rest feed-disabling motion, thus prevented the danger that left and right knife rest bumps.This protective device structure advantages of simple, low cost of manufacture, easy for installation, effectively improved the stability of lathe, effect is obvious.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in Figure 1, double tool rest vertical lathe knife rest anticollision device, collision-prevention device, it is included in the left socle 3 that is fixed on left knife rest 1 inner side and the right support 4 that is fixed on right knife rest 2 inner sides, and left and right support is positioned on same level line, at the front end of left knife rest, is provided with impact head 5.
As shown in Figure 2, at the front end of right support 4, fix a flange and support dish 6, one screw rod 8 parallel with right support 4 supports dish 6 through flange, screw rod 8 front ends are fixing with shock ring flange 7, at shock ring flange 7 and flange, on the screw rod body between dish 6, be set with resilient sleeve 9, be positioned at flange and support suit induction cover 10 on the screw rod body that coils 6 rear ends, the end of screw rod body is provided with rubber sleeve 11, on the right support position corresponding with rubber sleeve, is provided with inductive switch 12.
By reference to the accompanying drawings 1, accompanying drawing 2 and foregoing description known, when left and right support clashes into, screw rod is under the effect of resilient sleeve, the rubber sleeve 11 of its tail end is over against inductive switch 12, now inductive switch 12 no signals outputs.After left and right support clashes into, after screw rod 8, move, after induction cover 10 is corresponding, move, after induction cover 10 is relative with inductive switch 12, inductive switch 12 outputs signal to servo-drive system, and the knife rest of servo system control moves horizontally motor and quits work, the motion of left and right knife rest feed-disabling.
In this embodiment, inductive switch is selected approach switch, and correspondingly induction cover is selected metallic sheath.Certainly inductive switch can also be selected flexibly with induction cover, such as inductive switch, can select magnetic switch, travel switch etc., the corresponding selection thereupon of induction cover.
During installation, the length of left socle and screw front end are to the distance and the minimum approach distance that should be more than or equal to left and right knife rest of right support end.
