DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-2 The utility model provides the following technical solution: a clamping mechanism for a double-head welding gun, comprising:

[0026] Mounting frame 1;

[0027] A rotating frame 2, the rotating frame 2 is rotatably connected to the mounting frame 1;

[0028] The two clamping frames 3 are respectively fixedly connected to the two ends of the rotating frame 2, and the clamping frames 3 include a U-shaped seat 5 and a U-shaped cover 6. The U-shaped cover 6 is rotatably connected to one side of the opening of the U-shaped seat 5;

[0029] The adjusting frame 4 is fixedly connected to the middle of the rotating frame 2, and the lifting direction of the adjusting frame 4 is consistent with the opening direction of the clamping frame 3;

[0030] The rotation direction of the U-shaped cover 6 when it is opened is consistent with the rotation direction of the rotating frame 2 when it is flat.

[0031] As an optional implementation scheme of the utility model, a chamber that can accommodate the workpiece to be welded is formed between the U-shaped cover 6 and the U-shaped seat 5, and the adjustment frame 4 acts on the bottom surface of the workpiece, so that the clamping mechanism can be used for a variety of workpieces to be welded with a long length and any shape, and such a structural design allows the workpiece to have more space after being clamped so that the robot manual installation and transfer robot can clamp it, and also makes it convenient for the double-head welding gun to perform welding operations when the robot manual installation clamps the workpiece during welding.

[0032] Through the above structure, the technical solution forms a transfer platform that is convenient for welding clamping tooling and transfer manipulators to pick up and place, which is suitable for use with workpieces to be welded that are longer in length, and the clamping is stable and not easy to fall off.

[0033] like Figure 3 As shown, the rotating frame 2 includes a connecting plate 7 and a rotating shaft 8 , the connecting plate 7 is fixedly connected to the rotating shaft 8 at both ends, and the rotating shaft 8 is rotatably connected to the mounting frame 1 .

[0034] As an optional implementation scheme of the utility model, the rotating shaft 8 is rotatably connected to the mounting frame 1 through a bearing, so that the rotating frame 2 can rotate back and forth in the vertical and horizontal directions to facilitate manual installation and placement of the transfer machine and the welding clamping machine.

[0035] like Figure 1 As shown, a first electric push rod 9 is also rotatably mounted on the mounting frame 1 , and an ejection end of the first electric push rod 9 is rotatably connected to the connecting plate 7 .

[0036] As an optional implementation scheme of the utility model, the first electric push rod 9 drives the connecting plate 7 to rotate when in operation, so that the workpiece in the rotating frame 2 is switched between the horizontal direction and the vertical direction, so as to facilitate manual loading and unloading of the transfer machine and the welding clamping machine.

[0037] like Figure 3 As shown, the adjustment frame 4 includes a base 10, a third electric push rod 11 and a top plate 12. The base 10 is fixedly connected to the middle of the connecting plate 7, the third electric push rod 11 is fixedly connected to the base 10, and the top plate 12 is fixedly connected to the ejection end of the third electric push rod 11.

[0038] As an optional implementation scheme of the utility model, the third electric push rod 11 drives the top plate 12 to rise and fall, thereby abutting against the bottom of the workpiece to adapt to different workpiece specifications and ensure that workpieces of different specifications can be clamped by the clamping mechanism.

[0039] like Figure 1-2 As shown, a stop plate 13 is fixedly connected to the rotating frame 2 , and limit blocks 14 are provided on the mounting frame 1 and at both the front and rear sides of the stop plate 13 .

[0040] As an optional implementation scheme of the present invention, the limit block 14 prevents the rotating frame 2 from over-rotating, which causes the manual installation of the transfer machine or the manual installation of the welding clamping machine to fail to normally pick up and place the workpiece.

[0041] like Figure 1-2 As shown, sensing contacts 15 are provided on the mounting frame 1 and on both the front and rear sides of the abutment plate 13 .

[0042] As an optional implementation scheme of the utility model, any one of the sensing contacts 15 outputs an electrical signal after contacting the abutment plate 13, indicating that the workpiece is in a horizontal or vertical state, thereby controlling the corresponding tooling to perform a pick-and-place action. This is a prior art, so it will not be elaborated on.

[0043] like Figure 2-3 As shown, a second electric push rod 16 is rotatably mounted on the outer side of the mouth of the U-shaped seat 5, and the U-shaped cover 6 is rotatably connected to the U-shaped seat 5 through a clamping plate. One end of the U-shaped cover 6 close to the second electric push rod 16 extends outward, and the ejecting end of the second electric push rod 16 is rotatably connected to the extended end of the U-shaped cover 6.

[0044] As an optional implementation scheme of the present utility model, the second electric push rod 16 drives the U-shaped cover 6 to open or close the U-shaped seat 5 when in operation.

[0045] like Figure 1-3As shown, clamping blocks 17 are relatively fixedly provided at both ends of the U-shaped cover 6 and the U-shaped seat 5 .

[0046] As an optional implementation scheme of the present invention, the clamping block 17 is used to clamp the bent edge of the workpiece, so that the clamping mechanism can clamp the workpiece more firmly.

[0047] The working principle and use process of the utility model are as follows: after the double-head welding gun has welded the workpiece, the mechanical manual device for clamping the workpiece puts the workpiece into the clamping mechanism, then the U-shaped cover 6 is closed, and the adjusting frame 4 supports the bottom of the workpiece, the rotating frame 2 is rotated to vertical, the U-shaped cover 6 is rotated to open, the transfer mechanical manual device takes out the workpiece on the clamping frame 3, and puts in the workpiece to be welded by the double-head welding gun, then the U-shaped cover 6 is closed, and the adjusting frame 4 supports the bottom of the workpiece, the rotating frame 2 is rotated to horizontal, the U-shaped cover 6 is opened, and the mechanical manual device for clamping the workpiece takes the workpiece away.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
