Detailed Description
Referring to fig. 1 to 5, fig. 1 to 5 are schematic structural views of an embodiment of the present invention.
The flexible welding fixture for the automobile battery tray is mainly used for welding two or more battery trays which are different in length and comprise components such as lifting lugs, bushings and wire harness brackets, the shape and the characteristics of the outer frames of different battery trays are the same, the components such as the lifting lugs, the bushings and the wire harness brackets on the battery trays are also shared, and the difference is only that the length and the size of the trays and the positions of holes of the lifting lugs and the bushings are different.
As shown in fig. 1 to 5, a flexible welding fixture for an automobile battery tray comprises a fixture base 10, a first side bushing support 12 and a second side bushing support 13 for respectively supporting two sides of the battery tray to be welded in the length direction, and a first end bushing support 21 and a second end bushing support 11 for respectively supporting two ends of the battery tray to be welded in the length direction; the fixture base 10 is provided with a switching slide rail 17, the switching slide rail 17 is provided with a switching slide seat 20, the first end bushing support 21 is arranged on the switching slide seat 20, and the second end bushing support 11 is arranged on the fixture base 10.
Specifically, the switching slide rail 17 is parallel to the length direction of the battery tray to be welded, the switching slide 20 is in a long-strip plate-shaped structure, and the length direction of the switching slide 20 is perpendicular to the switching slide rail 17; the first side bushing support 12 and the second side bushing support 13 are both disposed on the fixture base 10. The end part bushing support II 11 and the side bushing support II 13 are both provided with a positioning fixed stop block 14, a side positioning cylinder 15 for fixing the side edge of the battery tray to be welded in the length direction is arranged at the side bushing support I12, and a side positioning baffle plate 16 is fixedly arranged on a piston rod of the side positioning cylinder 15; an end positioning cylinder 22 for fixing the end of the battery tray to be welded in the length direction is arranged on the switching slide seat 20, and an end positioning baffle 23 is fixedly arranged on a piston rod of the end positioning cylinder 22.
Further, a first lifting lug clamping assembly is arranged on the clamp base 10, and a second lifting lug clamping assembly is arranged on the switching slide seat 20. The first lifting lug clamping assembly and the first lifting lug clamping assembly comprise lifting lug clamping lifting cylinders 30, the cylinder barrels of the lifting lug clamping lifting cylinders 30 are fixedly arranged, piston rods of the lifting lug clamping lifting cylinders 30 are arranged upwards, lifting lug clamping seats 31 are arranged at the upper ends of the piston rods, and turnover lifting lug clamping blocks 32 are arranged on the lifting lug clamping seats 31. The fixture base 10 is further provided with a support positioning cylinder 40, a cylinder barrel of the support positioning cylinder 40 is fixedly arranged, a support positioning seat 41 is horizontally arranged on a piston rod of the support positioning cylinder 40, and the tail end of the piston rod is provided with a support positioning molded surface 42, and two support clamping plates 43 which are respectively positioned on two sides of the support positioning molded surface 42 are arranged on the support positioning seat 41.
Because the frame characteristics of two kinds of battery tray are the same, only the length size of two kinds of battery tray is different, therefore the locate mode is: according to a six-point positioning principle and the size requirement of a workpiece, selecting the bottom surface of the battery tray as a supporting reference surface; because the two products are provided with the wire harness support and the positions of the two products are the same, when the wire harness support is welded, the surface provided with the wire harness support is selected as one side surface reference, the installation position of the wire harness support can be ensured to be unchanged, and the position degree of the wire harness support of the two products can be ensured; one of the surfaces perpendicular to the other is arbitrarily selected as the other side reference, the remaining three surfaces are used as clamping surfaces for clamping and fixing, and a clamping mechanism on the side with the inconsistent length needs to be placed on the switching slider 20.
The positioning mode of the wire harness support is as follows: as shown in fig. 4, since the wire harness support has no hole and the battery tray has no positioning feature of the wire harness support, the positions of the wire harness support and the battery tray need to be positioned by a clamp, according to a six-point positioning principle and the size requirement of a workpiece, the side surface and the profile of the wire harness support are selected as the fixing reference of the wire harness support, and the other side surface of the wire harness support is used as a clamping surface, so that the wire harness support can be fixed on the clamp. Since the position of the harness support is the same in both battery trays, the harness support does not need to be mounted on the switching slide 20.
The positioning mode of the bushing is as follows: as shown in fig. 1-3, since the battery tray workpiece has a bushing hole, the side positioning can be performed according to the bushing hole of a given battery tray workpiece, the bushing hole is a through hole, and therefore the bushing needs to be supported and positioned, the positions of the bushings of two types of battery tray workpieces are not identical, and the bushings with different positions can be supported and positioned on the switching slide 20.
Lug locate mode: as shown in fig. 5, the features on the battery tray workpiece can be used for positioning the lifting lug, so that the fixture is not repeatedly positioned, and only a clamping mechanism of the lifting lug is needed.
While the preferred embodiments of the present invention have been described, it is to be understood that the present invention may be embodied in other forms than those described above, and that equivalent changes and modifications made by those skilled in the art without departing from the spirit of the present invention are intended to be included within the scope of the present invention.
