[0024] like Figure 1-5 As shown: A welding displacement system for automotive body-in-white includes a base 1, a tooling base 22, a telescopic mechanism, and a clamping mechanism;

[0025] A telescopic mechanism is provided on the base 1. Several straight connecting rods 23 are provided on the telescopic end of the telescopic mechanism. The first end of the double crank 6 is provided on the straight connecting rod 23. Several rotating shafts are provided on the base 1. The second end of the double crank 6 is connected to the rotating shaft. A tooling base 22 is provided on the rotating shaft. A clamping mechanism is provided on the tooling base 22. Workpiece 13 and workpiece 25 are detachably mounted on the tooling base 22. The clamping mechanism is used to clamp workpiece 13.

[0026] The telescopic mechanism is a telescopic cylinder; a telescopic cylinder base 2 is set on the base 1, and the telescopic cylinder is set on the telescopic cylinder base 2. The cylinder rod 10 of the telescopic cylinder is connected to the nearby straight connecting rod 23 through a joint 9. Several straight connecting rods 23 are connected to each other through hinge pins 5. The first end of the double crank 6 is connected to the straight connecting rod 23 through the hinge pin 5, and the second end of the double crank 6 is rotatably connected to the nearby rotating shaft. The telescopic cylinder and the rotating shaft use the double crank to form a crank-slider deformation structure, which satisfies the requirement that the linear motion of the cylinder is converted into a certain angle of rotational motion of the tooling base.

[0027] The clamping mechanism is a clamping cylinder 11; a clamping cylinder base 8 is provided on the tooling base 22, and the clamping cylinder 11 is mounted on the clamping cylinder base 8; a clamping support 21 is provided on the tooling base 22, and the first end of the workpiece 13 is detachably mounted between the clamping arm 12 of the clamping cylinder 11 and the clamping support 21. The clamping cylinder 11 is preferably a rotary pressing clamping cylinder.

[0028] The telescopic cylinder includes a left telescopic cylinder 3 and a right telescopic cylinder 24; the left telescopic cylinder 3 and the right telescopic cylinder 24 are symmetrically arranged on the same side of the base 1. Multiple tooling bases 22 on the left side of the entire system form a group, and their rotation is controlled by the left telescopic cylinder 3, allowing for the clamping of left-side parts. Multiple tooling bases 22 on the right side form a group, and their rotation is controlled by the right telescopic cylinder 24, allowing for the clamping of right-side parts. These can also be identical parts or mirror-symmetrical parts, allowing users to arrange the mechanism according to their specific needs.

[0029] A positioning seat 20 is provided on the tooling base 22, and a support 16 is provided on the positioning seat 20. The support 16 is perpendicular to the tooling base 22, and a number of positioning pins 14 are provided on the support 16. The workpiece is provided with holes that mate with the positioning pins 14.

[0030] A support 17 is provided on the tooling base 22. The support 17 is horizontally arranged with the tooling base 22, and a number of locating pins 18 are provided on the support 17. The workpiece 2 is provided with holes that mate with the locating pins 18.

[0031] Several bearing seats 4 are symmetrically arranged on the base 1, and a rotating shaft is provided on the bearing seat 4. The tooling base 22 is located between two rotating shafts. That is, the rotating shaft 7 closer to the telescopic cylinder and the rotating shaft 19 further away from the telescopic cylinder, which allows the tooling base to rotate.

[0032] The base 1 is a frame structure.

[0033] The tooling base 22 is a frame structure.

[0034] The steps for using this utility model are as follows:

[0035] The telescopic cylinders are activated to complete the extension and retraction actions, ensuring they are in normal working order. After placing six workpieces (Workpiece 1 and Workpiece 2) onto the fixture, the pneumatic clamping cylinders are engaged, constraining Workpiece 1 and Workpiece 2. At this point, both the left and right telescopic cylinders are extended. Simultaneously, the welding system is activated, welding the upper weld seam formed by the overlap of Workpiece 1 and Workpiece 2 under pre-tuned program instructions. After the upper weld seam is completed, the system automatically drives the telescopic cylinders to retract, causing all fixture bases to rotate by the same angle. The welding system then welds the seam in a different orientation. Once the entire process is complete, the system automatically releases the clamping cylinders, and the telescopic cylinders return to their initial state, allowing the operator to remove the welded workpieces.

[0036] At this point, proceed to the next welding process and the next process using the same method, repeating this process in sequence. After 10 welding cycles, clean all weld slag and spatter from the fixture base to ensure that the workpiece is placed in the correct position.

[0037] This invention features an automatic change of welding posture for multiple parts, which can replace manual adjustment of the welding posture of workpieces in batches, saving time and effort, and is highly efficient and energy-saving. It ensures that the weld seam on the workpiece is always in the optimal welding posture, effectively guaranteeing the welding quality of the workpiece and providing excellent safety. At the same time, it avoids the waste of frequent workpiece flipping by operators in harsh working environments. This principle can be widely applied in various fields.
