Accompanying drawing explanation
Fig. 1 is the structural representation of optimal way of the present invention.
Detailed description of the invention
The present invention is discussed in detail below in conjunction with Fig. 1:
The spot welding system of automobile production welding robot, including robot forearm 1 and mechanical hand 2, mechanical hand is hinged by wrist 4 and forearm 1, and mechanical hand is connected to welding gun 6, and the gas entered from wrist one end enters welding gun through mechanical hand, supplies for welding gun; The cooling water entered from the wrist other end enters welding gun electrode part through mechanical hand, then is partly refluxed to the other end described in wrist from electrode, carries out water circulation for welding gun electrode, takes away the heat of work; Meanwhile, flow through mechanical hand described in the gas of mechanical hand or cooling water-driven and elongate or shorten, thus the position of the welding gun regulated, it is ensured that welding gun is positioned at optimum welding position.
As preferably, described wrist 4 includes rotating hollow gyroaxis 42, the radial direction side of this gyroaxis is fixing connects described mechanical hand, the radial direction opposite side of gyroaxis is hinged with described forearm; forearm drives torch swinging; gyroaxis can drive welding gun to rotate, so that welding gun is in optimum welding position; Described mechanical hand is hollow manipulator, is arranged at the dividing plate 33 in the middle of mechanical hand inner chamber and mechanical hand is divided into airtight air cavity 36 and water cavity 37, it is ensured that air cavity and water cavity are each independent, is absent from the phenomenon revealed each other; Described gyroaxis inner chamber 43 two ends are separated by intermediate plate 44, make the inner chamber at two ends not be interconnected; The gas flowed into from described gyroaxis inner chamber one end flows into described welding gun through air cavity; The cooling water flowed into from the described gyroaxis inner chamber other end enters described welding gun electrode part through water cavity, then is partly refluxed to the other end described in gyroaxis inner chamber from electrode. Aforesaid way, it is achieved that mechanical hand supplies simultaneously and supplies water.
Described mechanical hand 2 includes hollow shell 21 and is arranged on the hollow inner shell 22 that this shell inner cavity and front end are closed by cover plate 3, inner shell is connected with described welding gun, described shell inner cavity and inner shell inner chamber constitute described mechanical hand inner chamber, described dividing plate 33 is made up of the front dividing plate 331 being arranged in the middle of inner shell inner chamber and the rear bulkhead 332 being arranged on shell inner cavity middle, before and after dividing plate can relative sliding, before and after this, described mechanical hand inner chamber is divided into described air cavity and water cavity by dividing plate;Inner shell described in the gas flowing through air cavity or the cooling water-driven flowing through water cavity stretches out or retraction shell inner cavity, thus driving welding gun to move.
As preferably, described gyroaxis 4 sidewall offers two through holes 41, one end and air cavity described in one of them through hole connection rotating shaft inner chamber, the other end and water cavity described in another through hole connection rotating shaft inner chamber; Described welding gun is arranged on described cover plate 3, and easy for installation, demolition and maintenance are simple; Cover plate 3 is provided with the water hole 31 connected with water cavity, and this water hole is connected with the water inlet of welding gun by water pipe 34; Described cover plate is provided with the pore 32 connected with air cavity, and this pore is connected with the air inlet of welding gun by trachea 35. In implementation process, it is necessary to during supply, make gases at high pressure enter air cavity from gyroaxis inner chamber one end by through hole, then pass through the pore of cover plate and the air inlet of trachea entrance welding gun from air cavity, thus supplying for welding gun; When needs supply water, cooling water is made to enter water cavity from the gyroaxis inner chamber other end by another through hole, entered the water inlet of welding gun again by water hole cover plate and water pipe from water cavity, thus the electrode part of Butt welding gun cools down, taking away heat, the water after electrode is cooled down directly is back to the gyroaxis inner chamber other end, again participates in circulation, owing to the water after electrode is cooled down is longer from the circuit of the rotating shaft inner chamber other end, it can natural cooling in cyclic process. The water of backflow also can be carried out heat exchange by implementation process so that it is after cooling, again participate in circulation again.
