Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a turning mechanism for welding vertical warehouse shelves. Background Art

[0002] When welding pallets on vertical warehouse racks, a tilting mechanism, known as a welding positioner, is required. However, existing welding positioners have a fixed internal frame structure, which lacks sufficient support and fixing points for larger pallets. This results in loose workpiece fixation and a tendency for the workpiece to tip over during the tilting operation. Furthermore, the lack of fixing points causes excessive stress on the fixture, accelerating wear.

[0003] Therefore, in order to solve the defect that the frame structure inside the welding turnover mechanism is fixed and cannot adapt to pallets of different sizes, it is necessary to propose a turnover mechanism for welding of vertical warehouse shelves. Utility Model Content

[0004] The purpose of the utility model is to provide a flip mechanism for welding vertical warehouse shelves. Through the sliding connection between frame one and frame two and the setting of supporting feet, the size of the frame can be flexibly adjusted according to the size of the pallet, thereby providing sufficient supporting area, effectively avoiding the situation where the workpiece is not firmly fixed due to insufficient support and fixing points, and also avoiding the problem of the fixture being subjected to excessive stress due to excessive local force.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0021] To address the technical issues of how to adjust the frame size, see Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0022] The flip mechanism for welding vertical warehouse shelves includes a base 1, a fixed frame 2 is bolted to one side of the upper end of the base 1, and a sliding frame 3 is provided on the other side for translation. A slide groove 101 is provided on the surface of the base 1, and a screw 102 is movably installed in the slide groove 101. One end of the screw 102 is fixedly connected to a motor 103. A slider 301 slidably connected to the slide groove 101 is welded to the bottom of the sliding frame 3, and the slider 301 is threadedly connected to the screw 102.

[0023] The fixed frame 2 is welded to the frame 5 through the turntable 4, and the sliding frame 3 is welded to the frame 7 through the turntable 6. The frame 5 and the frame 7 form a sliding connection. The lower surface of the frame 7 is equidistantly provided with adjustment holes 701. The frame 5 is detachably connected to a positioning pin 10 adapted to the adjustment hole 701.

[0024] Specifically, when the size of the frame needs to be adjusted, start the motor 103 to drive the screw 102 to rotate. Since the slider 301 is threadedly connected to the screw 102, and the slider 301 is slidingly connected to the slide groove 101, the slider 301 can drive the sliding frame 3 to translate along the axial direction of the screw 102, thereby driving the frame 2 7 to move, thereby adjusting the relative position between the frame 1 5 and the frame 2 7. After the adjustment is completed, insert the positioning pin 10 into the corresponding adjustment hole 1 701, thereby fixing the frame 2 7 and the frame 1 5 at the current position, thereby adjusting the frame size, and then adapting to pallets of different sizes, providing appropriate support and fixation for the pallets.

[0025] To solve the technical problem of how to adjust the support feet, please refer to Figure 3 , this embodiment provides the following technical solutions:

[0026] Support legs 9 are extended from the front and rear ends of frame 1 5 and frame 2 7 , and adjustment holes 901 are equidistantly provided on the side ends of the support legs 9 . Frame 1 5 and frame 2 7 are detachably connected with positioning pins 11 that match the adjustment holes 901 .

[0027] Specifically, first determine the position of the support foot 9 according to the size of the pallet. If the pallet is large, the support feet 9 need to be distributed more dispersedly. If the pallet is small, the support feet 9 need to be distributed more concentratedly. After determining the target position of the support foot 9, first pull out the positioning pin 2 11, and then move the support foot 9 along the frame 1 5 and the frame 2 7 until the support foot 9 can provide sufficient support for the pallet. Then insert the positioning pin 2 11 into the corresponding adjustment hole 2 901 to firmly fix the support foot 9 on the frame 1 5 and the frame 2 7, and complete the adjustment operation of the support foot 9.

[0028] See also Figure 2 The sliding frame 3 is fixedly mounted with a motor 2 8 , and the output end of the motor 2 8 is fixedly connected to the turntable 2 6 .

[0029] It should be noted that when welding operations are performed on different parts of the pallet, motor 28 is started to drive turntable 26 to rotate, turntable 26 drives frame 27 to rotate, and frame 27 drives the pallet to rotate until the pallet is rotated to a suitable angle, which makes it convenient for the welding equipment to weld the side of the pallet.

[0030] See also Figure 1 The upper surfaces of frame 1 5 and frame 2 7 are both provided with threaded holes 12 for fixing the fixture.

[0031] It should be noted that the presence of the threaded holes 12 enables the clamps to be installed at appropriate positions on the upper surfaces of frame 1 5 and frame 2 7 according to the size of the pallet, thereby stably fixing the pallet, and different types of clamps can also be installed through the threaded holes 12, thereby enhancing the versatility of the welding flip mechanism for different clamps, and multiple clamps can also be installed according to the threaded holes 12, thereby achieving multi-point fixation of the pallet.

[0032] Working principle: This vertical warehouse shelf welding flip mechanism, when in use, adjust frame 1 5 and frame 2 7 according to the size of the pallet, start motor 103, drive screw 102 to rotate, so that the sliding frame 3 is translated along the axial direction of screw 102, until the sliding frame 3 moves to the appropriate position, insert the positioning pin 10 into the corresponding adjustment hole 1 701, then adjust the support foot 9, pull out the positioning pin 2 11, move the support foot 9 until it moves to the appropriate position, and then insert the positioning pin 2 11 into the appropriate adjustment hole 2 901 to fix the support foot 9, and then select the threaded hole 12 in the appropriate position to install the clamp to fix the pallet, and then start the external welding equipment to weld the pallet. When the welding part needs to be adjusted, start motor 2 8 to drive the pallet to rotate until it is rotated to the appropriate angle, which is convenient for welding by the welding equipment.
