Abstract
Disclosed is a rotary scanning welding torch with a dust cover, wherein, a conduct pole is connected on a hollow shaft of the welding torch, and the upper part and the lower part of the conduct pole are connected with a self-aligning ball bearing and a bearing, respectively. The utility model is characterized in that the dust cover is connected at the front end of the self-aligning ball bearing on the conduct pole. The utility model has advantages that: (1) small ferrite beads and dust following the upward current of air can be prevented from entering a rotatable arc sensor; (2) the service life of the bearing in the rotatable arc sensor can be greatly extended; and (3) the service life and the precision of the rotatable arc sensor can be increased.
Description
Technical field
The utility model relates to a kind of welding torch, particularly a kind of rotation sweep welding torch with the dust-break lid.
Background technology
Arc sensor is a sensor of realizing the weld seam automatic real-time track.The point detection signal of arc sensor is exactly the welding arc point, does not have sensing station leading error, is complete real-time sensor, and is not afraid of that the splashing of electric arc, flue dust, arc light are disturbed, cost is low.At arc sensor, rotary scanning sensing is because of the scan frequency height, and scanning becomes optimal selection in the arc sensor continuously.The farming that jumps of Tsing-Hua University expense proposes circular cone pendulum scheme to rotary scaning welding torch in nineteen ninety, and progressively enters application after having developed RAT-1 type rotary arc sensor.Rotary arc sensor is in welding process, because welding position temperature height, and the rotary arc sensor upper temp is lower, therefore form by the air-flow of welding position to rotary arc sensor top, and the high temperature in when welding and the iron steam that forms and dust etc. along with this air-flow upwards, arrival rotary arc sensor inside, the cooling back forms tiny iron shot, because rotary arc sensor inside has many to bearing, the tiny iron shot that enters rotary arc sensor inside with thermal current greatly reduces the life-span of its internal bearings, even makes bearing to rotate.
Summary of the invention
The purpose of this utility model provides a kind of rotation sweep welding torch with the dust-break lid.Dust-break lid can stop with ascending air and enters the tiny iron shot of rotary arc sensor inside and dust etc., avoids the inner rolling bearing of rotary arc sensor to reduce the situation in service life because of the obstruction of tiny iron shot.
The utility model is achieved like this, it comprises welding torch, conducting rod, dust-break lid, hollow shaft, bearing, self-aligning ball bearing, on the hollow shaft of welding torch, connect conducting rod, conducting rod connect self-aligning ball bearing and bearing up and down respectively, it is characterized in that front end, connect the dust-break lid on the conducting rod at self-aligning ball bearing.The dust-break lid is for circular, and the centre is a trepanning, and the interior diameter of trepanning and conducting rod diameter match.
The utility model has the advantages that: (1) can stop little iron shot and the dust that enters rotary arc sensor inside with ascending air; (2) improve service life of rotary arc sensor internal bearings greatly; (3) service life and the precision of raising rotary arc sensor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a dust-break lid structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises welding torch, conducting rod 8, dust-break lid 6, hollow shaft 3, bearing, self-aligning ball bearing, on the hollow shaft 3 of welding torch 7, connect conducting rod 8, self-aligning ball bearing 1, following self-aligning ball bearing 5, upper bearing (metal) 2 and lower bearing 4 are gone up in connecting respectively up and down of conducting rod, it is characterized in that front end, connect dust-break lid 6 on the conducting rod 8 at following self-aligning ball bearing 5.The dust-break lid is for circular, and the centre is a trepanning 12, and the interior diameter of trepanning and conducting rod overall diameter match.In welding process, form welding arc 10 on the welded part 11, form high temperature because welding is local, and the rotary arc sensor upper temp is lower, has just formed ascending air from the bottom to top like this in rotary arc sensor inside; Simultaneously, because welding process wire melting or even vaporization form iron steam 9, add reason such as De Fei Splash in the welding process, rotary arc sensor carries out having a large amount of tiny iron shots in the welding tracking process and dust enters into rotary arc sensor inside with ascending air using, and exist many to self-aligning ball bearing and bearing in rotary arc sensor inside, after iron shot that these are tiny and dust enter, have a strong impact on its life-span.The utility model is narrow in iron shot and dust rising route, also be to enter before the rotary arc sensor inside simultaneously, one dust-break lid is set, what can effectively stop tiny iron shot and dust like this enters rotary arc sensor inside, the tiny iron shot that condenses in the rotary arc sensor front end be can remove easily again, thereby the service life and the precision of rotary arc sensor improved.
Claims (2)
1. rotation sweep welding torch with dust-break lid, it comprises welding torch, conducting rod, dust-break lid, hollow shaft, bearing, self-aligning ball bearing, on the hollow shaft of welding torch, connect conducting rod, conducting rod connect self-aligning ball bearing and bearing up and down respectively, it is characterized in that front end, connect the dust-break lid on the conducting rod at following self-aligning ball bearing.
2. the rotation sweep welding torch of band dust-break lid according to claim 1 is characterized in that: the dust-break lid is for circular, and the centre is a trepanning, and the interior diameter of trepanning and conducting rod overall diameter match.
