Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal welding, in particular to a welding device. Background Art

[0002] With the development and maturity of sheet metal processing technology, more and more machined parts are redesigned and replaced with sheet metal. Sheet metal parts are lighter in weight, easier to machine, more consistent, and cheaper than machined parts. Threaded mounting holes often appear on sheet metal parts. Since the sheet metal of sheet metal parts is generally thin, it is very difficult to directly process threaded holes on the sheet metal surface. Therefore, a common practice in actual processing is to open a round hole in the sheet metal and then weld the nut. For the nut welding work, the prior art usually requires an operator to place the nut above the round hole and then weld it to the sheet metal with a handheld spot welding gun. This operation method requires a lot of manpower costs and has relatively low work efficiency, which cannot meet the production needs of enterprises. In order to solve this problem, the present application discloses a welding device. Utility Model Content

[0024] Example

[0025] In order to solve a series of defects in the prior art of manually welding nuts on sheet metal, reference Figure 1 and Figure 2 As shown, the present application discloses a welding device, including a carrier 10, a forward and reverse driving mechanism 20, a nut grabbing and placing mechanism 30 and a welding mechanism 40;

[0026] The carrier is provided with a nut vibration plate 60 and a Y-axis moving platform 50 along the Y-axis direction, and a vacuum suction cup 80 is provided on the Y-axis moving platform;

[0027] A gantry truss 60 is provided along the X-axis direction on one side of the carrier in the Y-axis direction;

[0028] An X-axis moving platform 70 is provided on the crossbeam of the gantry truss on one side facing the nut vibration plate and the Y-axis moving platform;

[0029] The material grabbing and placing mechanism includes a first lifting column 31 and a pneumatic inner support clamp 32. The first lifting column is vertically slidably arranged on the front of the X-axis moving platform, and the pneumatic inner support clamp is fixed at the bottom of the first lifting column.

[0030] The welding mechanism includes a second lifting column 41 and a spot welding gun 42. The second lifting column is vertically slidably arranged on the front of the X-axis moving platform and is parallel to the first lifting column. The spot welding gun is fixed at the bottom of the second lifting column.

[0031] The forward and reverse drive mechanism includes a gear 22 and a forward and reverse drive assembly 21. The forward and reverse drive assembly is arranged on the back of the X-axis moving platform. The gear is arranged on the front outside of the X-axis moving platform and connects the driving part of the forward and reverse drive assembly to it. The first lifting column and the second lifting column are respectively provided with a first spur tooth portion 311 and a second spur tooth portion (not shown in the present invention) meshing with the gears on the opposite side surfaces.

[0032] During the specific working process, the operator places the sheet metal with multiple rows of round holes pre-opened on the vacuum suction cup and fixes it by the vacuum suction cup. The Y-axis moving platform drives the vacuum suction cup to move along the Y-axis so that the first row of round holes is located at the position to be welded, and then starts the nut grabbing and welding action. The X-axis moving platform moves to above the nut vibration plate and drives the gear to move in the opposite direction through the forward and reverse drive assembly. When cooperating with the first spur tooth portion on the first lifting column, the first lifting column is lowered, and when the first lifting column is lowered into place, a nut is grabbed from the nut vibration plate through the pneumatic inner support clamp (after the pneumatic inner support clamp grabs the nut, the forward and reverse drive assembly drives the gear to rotate forward to reset the first lifting column). After that, the X-axis moving platform moves toward the direction of the sheet metal, and after the pneumatic inner support clamp reaches the first round hole position, the forward and reverse drive assembly drives the gear to move in the opposite direction, and when cooperating with the first spur tooth portion on the first lifting column, the first lifting column is lowered, and When it is lowered into place, the nut is lowered into the round hole by resetting the pneumatic inner support clamp (after the pneumatic inner support clamp lowers the nut, the forward and reverse drive assembly drives the gear to rotate forward to reset the first lifting column). After the nut is placed, the X-axis moving platform moves above the sheet metal until the spot welding gun is directly above the nut. After that, the forward and reverse drive assembly drives the gear to rotate forward, and cooperates with the second spur tooth portion on the second lifting column to lower the second lifting column. After the spot welding gun is lowered into place, the nut is automatically welded to the sheet metal (after the spot welding gun finishes welding the nut to the sheet metal, the forward and reverse drive assembly drives the gear to reverse to reset the second lifting column). According to the above actions, the nuts are welded on a row of round holes of the sheet metal in turn. When welding is completed on a row of round holes of the sheet metal, the Y-axis moving platform drives the vacuum suction cup to move along the Y-axis so that the next row of round holes is located at the position to be welded, and the nuts are welded on the sheet metal again according to the above actions until the nuts are welded on all the round holes of the sheet metal.

[0033] In addition to the above structure, the present application also connects a feeder 91 to the output end of the nut vibration disk, and the end of the feeder is closed. During the nut feeding process, the nuts flowing out of the nut vibration disk will move in the feeder until they are blocked by the side wall at the end of the feeder, and then wait to be caught.

[0034] In this embodiment, a rectangular through groove 11 is opened on one side of the carrier in the X-axis direction, and the Y-axis movable platform includes a platform body 52 and two Y-axis servo screw modules 51. The two Y-axis servo screw modules are respectively arranged on the side walls on both sides of the rectangular through groove in the X-axis direction.

[0035] In this embodiment, the X-axis moving platform includes an X-axis servo screw module 71 and an inverted L-shaped platform 72. The X-axis moving platform is arranged above the crossbeam of the gantry truss. The horizontal part of the inverted L-shaped platform is connected to the X-axis servo screw module, and the vertical part is arranged toward the nut vibration plate and one side of the Y-axis moving platform. Driven by the X-axis servo screw module, the inverted L-shaped platform will move along the X-axis direction on the gantry truss.

[0036] In order to enable the first lifting column and the second lifting column to be lifted and slid, the present application arranges a first vertical guide rail 73 and a second vertical guide rail 74 on the vertical part of the inverted L-shaped platform, and the first lifting column and the second lifting column are slidably connected to the first vertical guide rail and the second vertical guide rail respectively. During the lifting process of the first lifting column and the second lifting column, the second lifting column and the second lifting column are lifted and slid on the first vertical guide rail and the second vertical guide rail respectively.

[0037] In one of the specific implementation schemes, the forward and reverse drive assembly includes a forward and reverse drive motor 211 and a reducer 212. The forward and reverse drive motor and the reducer are both arranged on the back of the inverted L-shaped platform.
