Description
Technical field
The utility model relates to a kind of process units, especially a kind of device that is applied to welding robot, specifically a kind of welding robot collision prevention device.
Background technology
At present; welding robot is when welding process and teach programming; often there will be welding gun to encounter the situation of workpiece and other barrier; cause the damaged and welding position of welding gun to be offset; directly have influence on the safety of producing and operating; when serious, can cause welding robot excess load to damage, or other serious security incident.For this reason, need to collision prevention device be installed to welding robot.But existing welding robot collision prevention device is mostly tailored version, only applicable a kind of robot and spy's welding gun, do not possess versatility, and great majority do not possess the function of spending the rear automatic recovery of collision in comprehensive scope at X-axis, Y-axis, Z axis 360.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of highly versatile is provided, and the welding robot collision prevention device accurately that can reset.
The technical solution of the utility model is:
A kind of welding robot collision prevention device, comprises the base being connected with robot actuating station, and the connecting axle being connected with welding gun top, and the central authorities of described base are provided with a through hole; Between described base and connecting axle, be provided with the disc spring fixed tray of a central protuberance, its lower surface and connecting axle upper surface fit, its projection stretches in the through hole of described base, and projection and around card on multiple springs in pressured state are installed; One side of described spring fixed tray is provided with a fulcrum, and this fulcrum contacts with the sensor that is installed on homonymy and be connected with robot controller.
Described projection spring is around for being uniformly distributed on spring fixed tray.
The longitudinal section of described connecting axle is T shape, and its underpart is set with a top cover being fixed on base, and is provided with annular shaft brace between this top cover and the upper base of connecting axle.
On described axle brace, be embedded with multiple and described spring steel ball one to one.
On described connecting axle upper base and top cover, be equipped with and diameter corresponding with described steel ball and be less than the locating hole of diameter of the steel ball, and steel ball is pressed between locating hole.
Described axle brace is provided with a spherical alignment pin, and on connecting axle upper base, is provided with the pin-and-hole corresponding with this alignment pin.
The beneficial effects of the utility model:
The utility model is reasonable in design, simple in structure, easy for installation, in the time of can effectively preventing that welding robot from bumping, the damage that Butt welding gun and robot etc. causes, and can be after robot rollback, guarantee the accurate return of welding gun, avoid the trouble of recalibrating or programming, not only improved the safety and stability of equipment operation, also reduced operating cost.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figures 1 to 3, the utility model comprises the base 1 being connected with robot actuating station, and the connecting axle 3 being connected with welding gun top.In the central authorities of described base 1, be provided with a through hole.Between described base 1 and connecting axle 3, be provided with the disc spring fixed tray 2 of a central protuberance, the upper surface of its lower surface and connecting axle 3 fits, its projection stretches in the through hole of described base 1, and projection and around card on multiple springs 6 in pressured state are installed.Described projection spring is around for being uniformly distributed on spring fixed tray 2.One side of described spring fixed tray 2 is provided with a fulcrum, and this fulcrum contacts with the sensor 7 that is installed on homonymy and be connected with robot controller.The longitudinal section of described connecting axle 3 is T shape, and its underpart is set with a top cover 5 being fixed on base 1, and is provided with annular shaft brace 4 between this top cover and the upper base of connecting axle 3.On this axle brace, be embedded with multiple and described spring 6 steel ball 8 one to one.On the upper base of described connecting axle 3 and top cover 5, be equipped with and diameter corresponding with described steel ball 8 and be less than the locating hole of diameter of the steel ball, and steel ball 8 is pressed between locating hole.On described axle brace 4, be also provided with a spherical alignment pin 9, and be provided with the pin-and-hole corresponding with this alignment pin on connecting axle 3 upper bases.
Operation principle of the present utility model is: when welding gun and barrier bump; fulcrum occurrence positions on the spring fixed tray joining with sensor changes; and send signal to control system by sensor; make welding robot stop action; to reach buffering collision of closed, effectively protect the not impaired object of welding gun and welding robot.After robot is return, under the thrust effects of connecting axle group springs how, and under the acting in conjunction of the spherical alignment pin on axle brace and steel ball, make welding gun get back to rapidly the initial position being knocked, thereby guarantee that the welding position of welding gun is not offset.When within the scope of X-axis, Y-axis, Z axis 360 degree impinge upon in the scope that device sets time, organize more spring and one to one many group steel balls guarantee that connecting axle can accurately return to and be knocked front home position.And when clashing into or rotation exceedes the safety value that device sets, make spherical alignment pin deviate from pin-and-hole and cannot reset time, sensor can send signal, makes periods of robot operation stop.Then, must after manual reset, get back to the position before shock, thereby guarantee that welding gun can accurately return to the welding position before shock.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
