The specific embodiment
Embodiment
The connection device of the automatic connecting and disconnecting of a kind of welding circuit, structure comprise bearing 5, electrode connection device 1, automatic extending-contracting apparatus 2, stopping means 3 and connecting plate 6 as shown in Figure 1.
Automatic extending-contracting apparatus 2 is fixed on bearing 5 sides, is used for driving electrode connection device 1 as drive unit and slides up and down, and as shown in Figure 5, comprises cylinder 21 and the mobile device that is moved up and down along bearing 5 by cylinder 21 drivings.Cylinder 21 has cylinder rod 22, and after cylinder 21 was opened, cylinder rod 22 can be by the jack-up that makes progress under compressed-air actuated effect.Mobile device comprises slide rail 23, slide block 24 and holder 25.Slide rail 23 is provided with two, be arranged in parallel on the side of bearing 5, and slide block 24 is stuck in slide rail 23 and can slides thereon, and the end of holder 25 1 sides and cylinder rod 22 connects firmly, and a relative side is fixed on the side of connecting plate 6.
Be connected with welded piece 7 when electrode connection device 1 is used for welding, shown in Fig. 2-3, comprise electrode block 11, expansion link 12, sleeve 13, spring 14, base 16 and Connection Block 17.Connection Block 17 is positioned at holder 25 tops, be fixed on simultaneously on the side of connecting plate 6, base 16 is fixed on Connection Block 17 tops, has tapped blind hole on the base 16, and the bottom of sleeve 13 has external screw thread and matches with tapped blind hole and make the bottom of sleeve 13 and base 16 be spirally connected fixing.
It is that the endoporus 151 of D font has anti-rotating function that check ring 15 has the cross section, as shown in Figure 4.
One end of expansion link 12 passes in the endoporus 151 of spring 14 and check ring 15, and the other end penetrates in electrode block 11, and the two is fixed through bolt hole 111 places by bolt
The side of electrode block 11 is electrically connected with the cable of soldering appliance 4, and the top of electrode block 11 has the projection that is used for increasing electrode block 11 and workpiece 7 contact friction forces that is matrix distribution, and the vertical cross-section of projection is trapezoidal.During welding, the top of electrode block 11 contacts with metal matter workpiece 7, realizes being electrically connected.
Connecting plate 6 is used for connecting electrode connection device 1 and automatic extending-contracting apparatus 2, is positioned on the slide rail 23 and is fixed on slide block 24 tops.
The course of work of this enforcement is as follows:
(1) welding circuit is connected
When the workpiece 7 on the production line needs welding, cylinder 21 starts, cylinder rod 22 protrudes upward, driving holder 25 moves up, and then drive connecting plate 6 upwards slides on slide rail 23, because connecting plate 6 is fixed on slide block 24 tops, the friction of connecting plate 6 and slide rail 23 just changes the friction of 23 of slide block 24 and slide rails into, and frictional force reduces.
Connecting plate 6 moves up and drives electrode connection device 1 simultaneously and move up, and when the top of electrode block 11 withstood on the workpiece 7, electrode block 11, cable 4 and workpiece 7 were communicated with, and form current loop, thereby had reached the loop condition of welding.
If connecting plate 6 continues to move up, when the top of connecting plate 6 contacted with limited block 32, connecting plate 6 stopped mobile, and cylinder rod 22 no longer protrudes upward.This moment, expansion link 12 was subjected to the pressure of electrode block 11, and expansion link 12 moves down in spring 14 and check ring 15, to keep stress balance, because the cross section of endoporus 151 is D font anti-rotation structure, had guaranteed that expansion link 12 moves down Shi Buhui and rotates.
(2) disconnect welding circuit
When welding is finished, cylinder rod 22 is regained downwards, driving holder 25, connecting plate 6 and electrode connection device 1 moves down, electrode block 11 disconnects with workpiece 7, workpiece 7 just can be transported on next station, interferes electric current shunting when having avoided welding simultaneously when having avoided workpiece 7 to carry, improve welding quality, and reduced hand labor intensity.
Certainly, the specific embodiment of the present invention is not limited to the above embodiments, the equivalent transformation that multiple mode all can be arranged between its various features, various feature, such as just can substituting with the mode of minitype motor driving leading screw as the cylinder in the automatic extending-contracting apparatus 2 of drive unit, get final product so long as can drive the power set of mobile device generation upper and lower displacement; Automatic extending-contracting apparatus 2 also can substitute with the two guide rod cylinder of long stroke; Also have, sleeve endoporus 151 can also be that the cross section is the fit system of polygonal Kong Yuzhu with the fit structure of expansion link 12 outer walls, and the anti-rotation effect is equally also arranged; The mode of connecting firmly that the bottom of sleeve 13 and base are 16 can also be other known connecting mode; Etc..Every connection device that does not break away from the automatic connecting and disconnecting of welding circuit that feature that claims of the present invention limit realizes is all thought to fall within protection scope of the present invention.
