Technical Field

[0001] The utility model belongs to the technical field of distribution box processing, in particular to a positioning structure for a distribution box welding fixture frame. Background Art

[0002] During the manufacturing process of the distribution box, the metal plates need to be welded so that multiple metal plates together form the distribution box. Welding is an important mechanical processing method in modern industrial production. During the box welding process, the weld needs to be in the best welding position to achieve the best welding effect.

[0003] The position of the fixture frame is different during the welding process for distribution boxes of different sizes. In order to improve the applicability of the welding fixture, the fixture frame is usually adjusted by sliding it and then tightening it with bolts. Since the bolt rod needs to be aligned with the limiting hole of the fixed base plate when tightening the bolt, it is slightly inconvenient. Therefore, a positioning structure for the distribution box welding fixture frame is needed, which can pre-position the movement of the welding fixture frame on the slide rail surface, so that when the fixture frame needs to be locked, the bolt rod can be easily aligned with the limiting hole of the fixed base plate, thereby improving the convenience of locking and alignment when the welding fixture frame is adjusted. Utility Model Content

[0009] Preferably, a clamp is installed on the surface of the clamp frame.

[0010] 1. The beneficial effect of the utility model is that the utility model can make the slide rod drive the hemispherical block to move vertically on the top of the fixed base plate through the coordinated use of the circular plate and the spring, and because the outer wall of the hemispherical block and the inner wall of the slot are both spherical surfaces, the hemispherical block can slide out of the slot, so as to achieve the pre-positioning of the movement of the welding fixture frame on the surface of the slide rail, so that when the fixture frame needs to be locked, the convenient alignment between the bolt rod and the limiting hole of the fixed base plate can be guaranteed, thereby improving the convenience of locking and alignment when the welding fixture frame adjusts its position.

To avoid the situation where the hand slips when directly rotating the bolt rod 6, a cylindrical box 8 is fixedly connected to the surface of the metal block 4, a plurality of slots 9 are opened on the surface of the fixed base plate 1, the number of the limiting holes 5 and the slots 9 is the same, the slots 9 are hemispherical slots, and a circular plate 10 is provided in the inner cavity of the cylindrical box 8.

The bottom end of the sliding rod 12 passes through the bottom of the cylindrical box 8 and is welded with a hemispherical block 13.

[0023] Embodiment 2:

[0024] Figure 1-4 The utility model shows a positioning structure for a distribution box welding fixture frame of an embodiment of the utility model, which includes a fixed base plate 1: a rail rod 2 is fixedly installed on the surface of the fixed base plate 1 by bolts, a fixture frame 3 is slidably connected to the surface of the rail rod 2, a metal block 4 is installed on the surface of the fixture frame 3, a plurality of limiting holes 5 are opened on the surface of the fixed base plate 1, a bolt rod 6 is threadedly connected to the inner wall of the metal block 4, a cylindrical box 8 is fixedly connected to the surface of the metal block 4, a plurality of card slots 9 are opened on the surface of the fixed base plate 1, a circular plate 10 is arranged in the inner cavity of the cylindrical box 8, and the top of the circular plate 10 is connected to the column A spring 11 is fixedly installed between the inner walls of the cylindrical box 8, a slide rod 12 is fixedly installed at the bottom of the circular plate 10, the bottom end of the slide rod 12 passes through the bottom of the cylindrical box 8 and is welded with a hemispherical block 13, the hemispherical block 13 is a hemispherical block, and a wear-resistant plate 14 is fixedly connected to the surface of the hemispherical block 13, the wear-resistant plate 14 is a wear-resistant ceramic plate, through the setting of the wear-resistant plate 14, the surface of the hemispherical block 13 is padded, thereby avoiding the hemispherical block 13 from being damaged by friction due to long-term use, and improving the service life of the hemispherical block 13, and a clamp 15 is installed on the surface of the clamp frame 3.

[0025] Working principle: When the utility model is used, the user drives the metal block 4 to move on the outside of the rail rod 2 by holding the clamp frame 3. At this time, the metal block 4 drives the hemispherical block 13 to move in the horizontal direction through the cylindrical box 8 and the sliding rod 12. Since the hemispherical block 13 is squeezed by the inner wall of the slot 9, the hemispherical block 13 drives the sliding rod 12 and the circular plate 10 to move up and compress the spring 11. When the clamp frame 3 moves to a suitable position, the hemispherical block 13 is aligned with the corresponding slot 9. At the same time, the resilience of the spring 11 drives the hemispherical block 13 into the inner cavity of the slot 9 through the circular plate 10 and the sliding rod 12, and the bolt rod 6 is aligned with the corresponding limiting hole 5. Then, the bolt rod 6 is rotated to enter the inner cavity of the limiting hole 5, thereby realizing the pre-positioning of the movement of the welding clamp frame on the slide rail surface, so that when the clamp frame needs to be locked, the convenient alignment between the bolt rod and the limiting hole of the fixed bottom plate can be guaranteed, thereby improving the convenience of locking and aligning when the welding clamp frame adjusts its position.

[0026] In summary, the positioning structure of the distribution box welding fixture frame, through the coordinated use of the circular plate 10 and the spring 11, can enable the slide bar 12 to drive the hemispherical block 13 to move vertically on the top of the fixed base plate 1, and because the outer wall of the hemispherical block 13 and the inner wall of the slot 9 are both spherical surfaces, the hemispherical block 13 can then slide out of the slot 9, which can achieve the pre-positioning of the movement of the welding fixture frame on the surface of the slide rail, so that when the fixture frame needs to be locked, it can ensure the convenient alignment between the bolt rod and the limiting hole of the fixed base plate, thereby improving the convenience of locking and alignment when the welding fixture frame adjusts its position.
