It is slidably connected on rail 9 there are two the first sliding panel 10, is welded and fixed spindle box 11 on two the first sliding panels 10 jointly, two the
One sliding panel, 10 lower end is welded with bottom plate 12 jointly, and 12 lower end of bottom plate is welded with support block 13, and 13 lower end of support block is provided with buffering dress
It sets, servo motor 5 is installed using bolt on lathe frame body 1, the output shaft of servo motor 5 is connected with using flat key interference fit
Driving gear 6, driving gear 6 are engaged with driven gear 7, and driven gear 7 is connected with ball-screw 4 using flat key interference fit,
Ball-screw 4 is rotatablely connected through the second support plate 3 and using rolling bearing and the second support plate 3, and the left end of ball-screw 4 is logical
It crosses rolling bearing and the first support plate 2 is rotatablely connected.Sliding rail 9 is cylindrical structure, is coaxially opened up on two the first sliding panels 10
Have and is coated with lubricating oil with the comparable through-hole of 9 diameter of sliding rail, the junction of sliding rail 9 and the first sliding panel 10；
Buffer unit includes pushing box 14, the second sliding panel 15, third sliding panel 16, sliding bar 17, rotation seat 18, T-type
Plate 19, spring 20, pushing box 14 is the box like structure on no box top, and 14 top of box is pushed to be welded with the second sliding panel 15, is pushed
Third sliding panel 16 is welded in box 14, the second sliding panel 15 and third sliding panel 16 slidably connect sliding bar 17 jointly, sliding
17 lower end of lever is welded with spring 20, pushes 14 inside lower wall of box to be welded with rotation seat 18, is rotated on rotation seat 18 using pin shaft
It is connected with T-type plate 19, spring 20 is welded on T-type plate 19 far from one end of sliding bar 17, and rolling is threaded on ball-screw 4
Pearl nut 8 pushes box 14 to be welded and fixed with ball nut 8.Rotation seat 18 is located at the middle part for pushing box 14, original state lower slider
Bar 17 is located at the right end of the second sliding panel 15, and spring 20 is tilted to the right at this time, and under the action of spring 20, sliding bar 17 is more
The stable right end for resting on the second sliding panel 15, when 17 stress of sliding bar is slided to the left and crosses the top of rotation seat 18,
The elongation of spring 20 pushes sliding bar 17 to slide to the left.
Sliding bar 17 includes upper body of rod 171, the first rotary table 172, the second rotary table 173, lower body of rod 174, and sliding bar 17 is one
Body casting and forming is made, and the first rotary table 172 and the second rotary table 173 on sliding bar 17 guarantee that sliding bar 17 can be slided with third
Plate 16 is stable to be slidably connected, and the first through hole of strip is offered on the second sliding panel 15, is offered on third sliding panel 16
Second through-hole of strip, upper body of rod 171 run through the second sliding panel 15 from first through hole, and the diameter of the first rotary table 172 is greater than
The width of first through hole, lower body of rod 174 run through third sliding panel 16 from the second through hole, and the diameter of the second rotary table 173 is greater than the
The width of two through-holes, third sliding panel 16 are Z-shaped structure, and the left end of third sliding panel 16 is lower than right end, when sliding bar 17 is sliding
When moving to the left end of third sliding panel 16, the height of 17 upper end of sliding bar is reduced, and makes sliding bar 17 can not be with support block 13 after continued access
Touching, avoids that sliding bar 17 continues to start building part with too fast speed band and tool contact causes tool damage；Driving gear 6 with it is driven
Transmitting avoids the revolving speed of servo motor too fast, guarantees that the velocity of rotation of ball-screw 4 is relatively reasonable than being 2:1 between gear 7.
In the utility model, starting servo motor 5 drives driving gear 6 to rotate, and driving gear 6 is driven by engagement
Driven gear 7 rotates, and then ball-screw 4 is driven to rotate, since ball nut 8 is threadedly coupled with ball-screw 4, so ball
When lead screw 4 rotates, ball nut 8 can be slided to the right, push 14 part-structure of box to slide to the right together, and then make sliding bar 17
It pushes support block 13 that spindle box 11 thereon is driven to slide to the right, so that workpiece and tool contact is started to work, the feeding of workpiece at this time
Speed is appropriate, and sliding bar 17 and the dynamics that support block 13 offsets are moderate, since reaction force of the support block 13 to sliding bar 17 is moderate, bullet
The decrement of spring 20 is limited；
When the program of numerically controlled lathe go wrong cause workpiece feeding it is too fast when, sliding bar 17 with biggish dynamics with support
Block 13 offsets, or occur sliding bar 17 hit support block 13 when, sliding bar 17 is larger by the reaction force of support block 13, at this time
20 forced compression amount of spring is larger, and 17 stress of sliding bar is slided to the left, when the sliding of sliding bar 17 makes spring 20 cross vertical state
When becoming to be tilted to the left, spring 20 has the tendency that freely extending, and the continuation of sliding bar 17 is pushed to the left, at this time pushing away in spring 20
Under power effect, sliding bar 17 is disengaged with support block 13 to the left, when sliding bar 17 moves to the left end of third sliding panel 16, by
It is lower than right end in the left end of third sliding panel 16, it contact the upper end of sliding bar 17 can not with support block 13, even if so rolling at this time
The continuation of pearl nut 8 is slided to the right, and sliding bar 17 can not also contact with support block 13 and 13 part-structure of support block is driven to move right,
And then it avoids workpiece and continues with too fast feed speed and tool contact, and then avoid the damage of cutter；
When can not work normally lathe when sliding bar 17 slides into the left side of third sliding bar 16, user should be immediately
Lathe and self-test numerical control program are closed, then restores ball nut 8, spindle box 11 to initial position.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to~equivalent substitution or change, should all cover the protection in the utility model
Within the scope of.
