A kind of burning torch collision detection and automatic runback device
Technical field:
The present invention relates to a kind of burning torch collision detection and automatic runback device.
Background technology:
Burning torch is the instrument of the band valve of gas cutting, and shape has nozzle like rifle, front end, is commonly used in CUT
On, but situation burning torch collision easily occurring in cutting process and damaging, the gun body determining angle groove head of present stage is all
It is to be directly anchored on clamping device, is then fixed on together with clamping device on fork, the most in use, when burning torch rifle head
During the barrier collided, gun body is often damaged, and even can damage head, thus increase cutting error, increase equipment simultaneously
Maintenance cost, affects production efficiency.In the prior art, in order to prevent burning torch damaged in collision, it is all manually to find collision, manually
Shutting down, artificial response speed is slow, and it some times happens that neglect, it is impossible to make a response timely.
Summary of the invention:
The purpose of the present invention is aiming at the disadvantages mentioned above that prior art exists, devise a kind of burning torch collision detection and from
Resetting means, present configuration is reasonable, burning torch when encountering barrier can autostop, and after clearing, energy
Enough automatically restore, stopped the possibility that burning torch gun body is damaged, and improve work efficiency, solve and ask present in prior art
Topic.
The present invention solves that above-mentioned technical problem be the technical scheme is that
A kind of burning torch collision detection and automatic runback device, including base, be provided with a through hole on base, be provided with in through hole
One angular contact articulated bearing, described angular contact articulated bearing includes inner ring and outer ring, bottom outer ring be located on through-hole wall
One annular boss abuts, and inner ring top abuts a burning torch clamper, and described burning torch clamper includes lower supporting plate and burning torch clamping
Portion, the bottom of lower supporting plate abuts with inner ring, and the top of lower supporting plate abuts one and is sleeved on the annular pressing plate on burning torch clamper,
In base, it is provided with some pressing plate returning devices being movably connected with annular pressing plate, base is installed with some positions and annular
The microswitch component that press plate position is correspondingly arranged, microswitch component is connected with controller by wire.
Preferably, described pressing plate returning device includes that one connects through annular pressing plate and the bolt of base, bolt screw top
Connect a nut abutted with annular pressing plate, bolt is provided with the spring abutted with base and boss the most respectively.
Preferably, described microswitch component includes microswitch support, and microswitch support is connected with base, in fine motion
Switch bracket is provided with the microswitch for detecting annular pressing plate motion, and microswitch is connected with controller by wire.
Preferably, described base is provided with the some connecting holes for being connected with rocking bar.
Preferably, described microswitch component at least 3.
Preferably, described pressing plate returning device at least 3.
Compared with prior art, the invention have the advantage that rational in infrastructure, when burning torch rifle head runs into barrier, pressing plate exists
Under the effect of angular contact articulated bearing, position changes, after jogging switches measurement changes to press plate position, and control system
Make rifle head be automatically stopped motion, the most whether use and whether manually or automatically operate, burning torch rifle head is moved to home, when
After dangerous releasing, under the active force of pressing plate returning device, this device and rifle head can set back, under proceeding automatically
One step work.

Detailed description of the invention:
For the technical characterstic of this programme can be clearly described, below by detailed description of the invention, and combine its accompanying drawing, to this
Bright it is described in detail.
As shown in Figure 1-2, a kind of burning torch collision detection and automatic runback device, including base 1, base 1 is provided with one and leads to
Hole, is provided with an angular contact articulated bearing in through hole, and described angular contact articulated bearing includes inner ring 2 and outer ring 3, bottom outer ring 3
Abutting with the annular boss 4 being located on through-hole wall, inner ring 2 top abuts a burning torch clamper, described burning torch clamper bag
Including lower supporting plate 5 and burning torch clamping part 6, the bottom of lower supporting plate 5 abuts with inner ring 2, and the top of lower supporting plate 5 abuts a suit
Annular pressing plate 7 on burning torch clamper, is provided with some pressing plate returning devices being movably connected with annular pressing plate 7 in base 1,
Being installed with the microswitch component that some positions are correspondingly arranged with annular pressing plate 7 position on base 1, microswitch component passes through
Wire is connected with controller.
Described pressing plate returning device includes that one connects one through annular pressing plate 7 and the bolt 8 of base 1, bolt 8 screw top
The nut 9 abutted with annular pressing plate, is provided with the spring 10 abutted with base 1 and boss 4 the most respectively on bolt 8.
Described microswitch component includes that microswitch support 11, microswitch support 11 are connected with base 1, open in fine motion
Closing support 11 and be provided with the microswitch 12 for detecting annular pressing plate 7 motion, microswitch 12 is by wire and controller phase
Even.
Described base 1 is provided with the some connecting holes 13 for being connected with rocking bar.Conveniently it is connected with rocking bar.
Described microswitch component at least 3.
Described pressing plate returning device at least 3.Owing to angular contact articulated bearing motion is various, it is impossible to open with a fine motion
Close assembly or pressing plate returning device carries out complete detection to presser motion mode.
During use, first this device is connected by connecting hole 13 with rocking bar, is then firmly cut by burning torch gripper
Rifle, the most just can process need to process workpiece under the control of the controller.When encountering barrier, burning torch drives burning torch
Clamper moves, and burning torch clamper can drive inner ring 2 to move, and in view of the feature of angular contact articulated bearing, which type of burning torch has
Motion, all can have embodiment on the inner ring 2 of angular contact articulated bearing.Owing to when inner ring 2 moves along outer ring 3, meeting is according to burning torch
Clamper passes to the direction of inner ring 2 active force and deflects, after inner ring 2 deflects, can drive abutting lower supporting plate 5,
There is axially-movable in annular pressing plate 7, the microswitch 12 being now located at bore periphery can detect the displacement of its motion, the most micro-
Dynamic switch 12 sends signal to controller, and controller controls complete machine stop motion.Then controller sends to complete machine and transports to before this
The signal in dynamic direction in opposite direction, so makes burning torch depart from collision status, continues next step work the most under control of the controller
Make.
Above-mentioned detailed description of the invention cannot function as limiting the scope of the invention, for the technology people of the art
For Yuan, any alternate modification being made embodiment of the present invention or conversion all fall within protection scope of the present invention.
The present invention does not describes part in detail, is the known technology of those skilled in the art of the present technique.
