Description
Technical field
The applicable lathe protection technology field of the present invention, more particularly, to a kind of lathe anti-collision protection device.
Background technology
At present, the lathe such as China's NC vertical lathe, digital control plane milling and boring machine, vertical machining centre, largely possesses
Double tool rest structure, in order to prevent the maloperation due to operator, cause double tool rest to crash, such lathe can all be set
There is double tool rest anti-collision protection device.Found according to market survey, anti-collision protection device most at present is using following structure:
Two crash-proof brackets are installed in one end similar in the knife rest of left and right, crash-proof bracket front end is equipped with protection rubber blanket and inductive switch, rubber
Rubber cushion and collision block intimate contact.Such a structure two knife rests close to when, collision block can first collide；Then compression protection rubber
Pad continues to compress, inductive switch is sent alarm signal as certain buffering；Machine tool numerical control system is fed back, pressure makes driving left
The motor brake of right knife rest；Because the unstable factor such as the sensitivity level of inductive switch and the translational speed of left and right knife rest,
It usually can be destroyed protection rubber blanket, therefore anti-collision protection device is scrapped, every precision of left and right knife rest also can be by
Different degrees of destruction, the use of lathe is had a strong impact on, certain economic loss is brought to company.
The content of the invention
To overcome above mentioned problem, the present invention adopts the following technical scheme that：
A kind of lathe anti-collision protection device, including left knife rest and right knife rest, the right-hand member of left knife rest are provided with left crash-proof bracket, right knife rest
Left end be provided with right crash-proof bracket, right crash-proof bracket is provided with rubber sleeve, and noncontacting switch is fixed on right anticollision branch by nut
On frame, and positioned at the middle part of rubber sleeve, rubber sleeve left end is shank of bolt, and rubber sleeve, support set, sensing set are connected on by shank of bolt
Together, and with nut position right-hand member, collision block and fixed plate are screwed the left end in shank of bolt；Rubber sleeve right-hand member be every
Pad, the right-hand member of dottle pin is spring, and the right-hand member of spring is jackscrew, and jackscrew is fixed on the right side of right crash-proof bracket by threaded connection mode
End.
The left crash-proof bracket and right crash-proof bracket are on the same line.
It is an advantage of the invention that：The present apparatus is novel in design, simple and stable structure, saves space, cost-effective, at work
Peace adjust and it is easy to maintenance, fast, and substantially increase machine safety and reliability, there is certain dissemination.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the internal structure schematic diagram of the present invention.
Embodiment
As shown in Figure 1, 2, a kind of lathe anti-collision protection device, including left knife rest 1 and right knife rest 2, the right-hand member of left knife rest 1 are set
There is left crash-proof bracket 3, the left end of right knife rest 2 is provided with right crash-proof bracket 15, and right crash-proof bracket 15 is provided with rubber sleeve 10, contactless
Switch 11 is fixed on right crash-proof bracket 15 by nut, and positioned at the middle part of rubber sleeve 10, the left end of rubber sleeve 10 is shank of bolt
7, rubber sleeve 6, support set 8, sensing set 9 are cascaded, and position right-hand member with nut by shank of bolt 7, collision block 4 and fixed plate
5 are screwed in the left end of shank of bolt 7；The right-hand member of rubber sleeve 10 is dottle pin 12, and the right-hand member of dottle pin 12 is spring 13, spring 13
Right-hand member is jackscrew 14, and jackscrew 14 is fixed on the right part of right crash-proof bracket 15 by threaded connection mode.
The left crash-proof bracket 3 and right crash-proof bracket 15 are on the same line.
Operation principle is as follows：
When left and right sides knife rest bumps against, left crash-proof bracket 3 is first contacted with collision block 4, and collision block 4 is fixed on together with fixed plate 5
The left end of shank of bolt 7.Because left crash-proof bracket 3 is rigid trestle, movement will not be produced, shank of bolt 7 is promoted sensing set 9
And crash-proof bracket 15 moves compression spring 13 to the right together for rubber sleeve 10, dottle pin 12.Before collision, noncontacting switch 11
It is fixed on right crash-proof bracket 15, and among rubber sleeve 10, will not now produces signal.After collision, rubber sleeve 10,
Sensing set 9 can all move crash-proof bracket 15 to the right.When rubber sleeve 10 is moved away from inductive switch, sensing set 9 is moved to contactless open
11 positions are closed, fixed plate 5 not yet contacts with rubber sleeve 6, noncontacting switch 11 is produced signal, and signal feeds back to number
Control system, make system alarm, system makes left and right knife rest motor stall, so as to which left and right knife rest stops movement.It is so effective
Ground avoids the substantial collision of left and right knife rest.Even left and right knife rest is drawing close contact with prestissimo, due to feeding back with holding
Row existence time is poor, and knife rest will not be made to stop moving at once, may proceed to compressing rubber set 6 and spring 13, rubber sleeve 6 and spring
It is elastic caused by 13, the impulsive force of cutter setting frame is efficiently reduced, cutter setting frame serves safeguard protection effect.
