DETAILED DESCRIPTION

[0017] according to Figures 1 to 5The specific structure of the utility model is described in detail. The stir friction welding flash cleaning device includes a frame 1, a horizontally arranged platform 2 is provided on the upper part of the frame 1, and a cathode beam positioning pad 3 for placing the welding cathode beam 9 is provided on the upper side of the platform 2. A positioning groove 17 arranged transversely along the extension direction of the cathode beam is provided on the upper side of the cathode beam positioning pad 3, and the longitudinal width of the positioning groove 17 is greater than the longitudinal width of the welding cathode beam 9, so as to facilitate the positioning of the side of the welding cathode beam 9 and the cathode beam conductive head 11 respectively after the welding cathode beam 9 is turned over; at the same time, two groups of conductive head cleaning card grooves 18 are provided in the positioning groove 17 for embedding the protruding cathode beam conductive head 11. Then, the middle part of the welding cathode beam 9 is positioned and placed in the positioning groove 17 of the cathode beam positioning pad 3, so as to use the reciprocating planer mechanism 8 to clean the welding flash at the welded cathode beam hanging ear 10. Moreover, when it is necessary to clean the flash of the cathode beam conductive head 11 welded at the end of the cathode beam, the cathode beam conductive head 11 welded at the end of the cathode beam 9 is positioned and placed in the conductive head cleaning slot 18 of the positioning slot 17. It can be understood that the purpose of setting two sets of conductive head cleaning slots 18 is to facilitate the positioning of the side of the welded cathode beam 9 and the cathode beam conductive head 11 after the cathode beam is turned over.

[0018] A material pressing block 4 is arranged above one end of the cathode beam positioning pad 3 on the platform 2, and a material pressing driving cylinder 5 is arranged below the material pressing block 4. A material pressing block lifting slide column 24 is arranged on both sides of the material pressing block 4, and the material pressing block lifting slide column 24 extends downward to the bottom of the platform 2 through two corresponding material pressing block lifting guide holes 19 arranged on the platform 2. In addition, the lower ends of the two material pressing block lifting slide columns 24 are also fixedly connected to the lifting connecting plate 25; the lower side of the lifting connecting plate 25 is fixedly provided with a material pressing driving cylinder 5 arranged vertically, and the telescopic end of the upper part of the material pressing driving cylinder 5 is provided with a material pressing cylinder telescopic screw 26, and the upper end of the material pressing cylinder telescopic screw 26 is rotatably connected to the lower side of the platform 2. Thus, the extension and retraction of the telescopic screw 26 of the press drive cylinder 5 is utilized to drive the press block 4 above it to rise or fall along the press block lifting slide 24, so as to press and fix the welded cathode beam 9 placed in the cathode beam positioning pad 3, so as to facilitate the subsequent cleaning operation of the planer mechanism 8.

[0019] A planer mechanism 8 for cleaning the welding burrs of stir friction welding is also provided above the other end of the cathode beam positioning pad 3. The end of the planer mechanism 8 is connected to the planing sliding mechanism 6 provided on the platform 2, and the driving end of the planing sliding mechanism 6 is connected to the planing driving hydraulic cylinder 7.

[0020] The planer mechanism 8 includes a planer connecting frame 20 connected to the planing sliding mechanism 6, and a vertically arranged planer lifting cylinder 21 is provided at the front end of the planer connecting frame 20. The telescopic end of the lower part of the planer lifting cylinder 21 is connected to the planer adapter 22, and a flash cleaning planer 23 is detachably provided on the lower side of the planer adapter 22; the flash cleaning planer 23 provided on the planer connecting frame 20 is used to plan and clean the two cathode beam hanging ears 10 on the welding cathode beam 9 and the front and back sides of the cathode beam conductive head 11. In addition, the flash cleaning planer 23 is driven to rise and fall by the telescopic movement of the planer lifting cylinder 21, so as to facilitate the upper and lower parts of the welding cathode beam 9. At the same time, a knife sleeve is fixedly provided on the outer side of the planer adapter 22 and below the end of the planer connecting frame 20; the knife sleeve is used to protect the flash cleaning planer 23 in the retracted state, so as to avoid accidental collision and damage to the knife body during the upper and lower parts.

[0021] Moreover, the planing sliding mechanism 6 includes a planing cylinder connection seat 12 arranged on the platform 2, and a planing driving hydraulic cylinder 7 arranged along the extension direction of the cathode beam is arranged on the planing cylinder connection seat 12, and the telescopic end of the planing driving hydraulic cylinder 7 is connected to the sliding connection plate 16, and the planing blade connection frame 20 of the planing blade mechanism 8 is fixedly connected to the sliding connection plate 16 of the planing sliding mechanism 6; the lower side of the sliding connection plate 16 is slidably connected to the sliding guide rail 14 through the sliding block 15. Then, the sliding connection plate 16 is driven to reciprocate along the sliding guide rail 14 by the telescopic movement of the planing driving hydraulic cylinder 7, so that the planing blade mechanism 8 can clean the welding flash of each welding part.

[0022] When the friction stir welding flash cleaning device is used, first, the middle part of the welding cathode beam 9 is placed in the positioning groove 17 of the cathode beam positioning pad 3, and the side of the welding cathode beam 9 where the cathode beam hanging ear 10 is not provided is close to the inner side wall of the positioning groove 17, and the welding part of the cathode beam hanging ear 10 is located below the planer mechanism 8. Then, the material pressing driving cylinder 5 is started to drive the material pressing block 4 to press downward along the pressing block lifting slide column 24, thereby pressing and fixing the welding cathode beam 9 placed in the cathode beam positioning pad 3. Afterwards, the planer lifting cylinder 21 is used to extend and retract to drive the planer adapter 22 and the flash cleaning planer 23 thereon to extend out from the protective tool sleeve (the height position of the planer has been adjusted); then, the planing drive hydraulic cylinder 7 is started, and the sliding connecting plate 16 and the planer mechanism 8 arranged thereon are driven to reciprocate along the sliding guide rail 14 through the extension and retraction of the planer drive hydraulic cylinder 7, thereby realizing the cleaning of the welding flash of the cathode beam lifting ear 10 by the flash cleaning planer 23.

[0023] Since the thickness of the cathode beam conductive head 11 is not consistent with the thickness of the cathode beam body, when cleaning the welding flash at the cathode beam conductive head 11, it is necessary to move the welding cathode beam 9 so that the cathode beam conductive head 11 at the end of the cathode beam is embedded in the conductive head cleaning slot 18 of the cathode beam positioning pad 3 to facilitate processing. After the cathode beam conductive head 11 is positioned, the planing drive hydraulic cylinder 7 is started again, and the planer mechanism 8 is used to clean the welding flash at the welding position of the cathode beam conductive head 11. After the welding flash on the front side (one side) of the welding cathode beam 9 is cleaned, the planer adapter 22 and the flash cleaning planer 23 of the planer mechanism 8 are retracted, the welding cathode beam 9 is taken out and turned over, and the above steps of close positioning, pressing, extending the planer, and cleaning the flash are repeated to clean the welding flash at various places on the back side (the other side) of the cathode beam.
