[0002] In the industrial manufacturing system, end caps are key components of core equipment such as motors, pumps, valves, pressure vessels, and automotive transmissions. They play important roles in sealing, protection, and positioning. Their application scenarios cover multiple industries such as new energy vehicles, high-end equipment manufacturing, petrochemicals, and medical devices. As downstream industries continue to increase their requirements for equipment precision, reliability, and service life, the processing standards for end caps are becoming more stringent.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example: See Figures 1 to 5 This utility model discloses a laser welding workbench for end cap processing, comprising a machine base 1, which facilitates the installation of a four-jaw caliper 2, a cylinder 3, and a robotic arm 4. The four-jaw caliper 2, cylinder 3, and robotic arm 4 are mounted on the top surface of the machine base 1. The cylinder 3 is located at the rear end of the four-jaw caliper 2, and the robotic arm 4 is located on one side of the four-jaw caliper 2. The four-jaw caliper 2 facilitates the clamping of the end cap. The cylinder 3 facilitates the lifting and lowering of a first mounting rod 7. A support mechanism is mounted on the upper end of the cylinder 3, and a laser welding head 5 is mounted on the other end of the robotic arm 4, facilitating laser welding of the end cap. Anti-slip grooves 17 are formed on the inner sides of the four jaws of the four-jaw caliper 2 to prevent the end cap from sliding during rotation. The four-jaw caliper 2 is rotatably mounted at the center of the top surface of the machine base 1. A first mounting groove is formed inside the machine base 1, and a first motor 6 is installed in the first mounting groove, facilitating the rotation of the four-jaw caliper 2. The output end of the first motor 6... The support mechanism, connected to the center of the bottom surface of the four-jaw caliper 2, includes an L-shaped first mounting rod 7 installed at the output end of the cylinder 3. The first mounting rod 7 facilitates the installation of the second motor 8 and the lead screw 9. One end of the first mounting rod 7 has a second mounting groove, in which the second motor 8 is installed, facilitating the rotation of the lead screw 9. The output end of the second motor 8 is connected to the lead screw 9 via a coupling, facilitating the movement of the mounting box 10. The lead screw 9 is threadedly connected to the mounting box 10, facilitating the installation of the electric actuator 11. A first T-shaped block is fixed to the top of the mounting box 10. The bottom surface of the first mounting rod 7 has a T-shaped groove that moves with the mounting box 10. The inside of the mounting box 10 has a third mounting groove, in which the electric actuator 11 is installed, facilitating the movement of the positioning sleeve 12. The output end of the electric actuator 11 is fixed to the positioning sleeve 12, facilitating the installation of the second mounting rod 14.

[0016] In this utility model, a cross-shaped mounting groove is provided on the front end face of the mounting box 10. A cross-shaped limiting plate 13 passes through the opening of the cross-shaped mounting groove. The cross-shaped limiting plate 13 facilitates the movement of the positioning sleeve 12 in conjunction with the support rod 16 to move outward. The output end of the electric push rod 11 is inserted into the center of the cross-shaped limiting plate 13. The cross-shaped limiting plate 13 is located between the mounting base of the electric push rod 11 and the positioning sleeve 12. Multiple second mounting rods 14 are equidistantly installed around the periphery of the positioning sleeve 12. The second mounting rods 14 facilitate the installation of the hinge rod 15. Two hinge rods 15 are hinged to the second mounting rods 14. The hinge rods 15 facilitate the movement of the support rod 16 outward to clamp the inner wall of the welded part. The other end of the two hinge rods 15 is hinged to the support rod 16. A second T-shaped block is fixed to the rear end of the support rod 16. The cross-shaped limiting plate 13 has sliding grooves at all four ends to cooperate with the movement of the support rod 16. The second T-shaped block passes through the sliding grooves.

[0017] Working principle: When using this utility model, first, power on the device, then place the end cap to be processed on the four-jaw caliper 2. The anti-slip texture 17 on the inner side of the four jaws of the four-jaw caliper 2 firmly clamps the end cap, preventing slippage or displacement during subsequent welding. Next, place the workpiece onto the support rod 16 of the support mechanism. Then, start the electric actuator 11. The output end of the electric actuator 11 drives the positioning sleeve 12 to slide. The hinge rod 15 on the second mounting rod 14 on the periphery of the positioning sleeve 12 rotates as the positioning sleeve 12 slides, thereby driving the support rod 16 to move outward along the sliding grooves at the four ends of the cross limiting plate 13, so that the support rod 16 abuts against the welding. The inner wall of the component is used to stably clamp and position the welded component. Cylinder 3 is activated, which pushes the support mechanism to lift and lower the welded component to a suitable height. Then, the second motor 8 is activated, which drives the lead screw 9 to rotate, driving the mounting box 10 to move the welded component to the vicinity of the end cap. Finally, the robotic arm 4 is activated, which drives the laser welding head 5 to the welding position to perform laser welding on the end cap and the welded component. During the welding process, the first motor 6 is activated, which drives the four-jaw caliper 2 to rotate. The angle of the end cap can be adjusted according to the welding requirements to improve the flexibility and accuracy of the welding. After the entire welding process is completed, the end cap is removed and the power is disconnected.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
