Description

Technical Field

[0001] This utility model relates to the field of vacuum bubble pressure sealing technology, and more specifically, to a self-weight pressure sealing device. Background Technology

[0002] Vacuum circuit breakers mainly consist of three parts: vacuum interrupter, electromagnetic or spring operating mechanism, support, and other components. The vacuum interrupter, also known as a vacuum bubble, is the core component of medium and high voltage power switches. Its main function is to quickly extinguish the arc and suppress the current after the medium and high voltage circuit is cut off by utilizing the excellent insulation of the vacuum inside the tube, thus preventing accidents and incidents. It is mainly used in power transmission and distribution control systems and features energy saving, material saving, fire prevention, explosion protection, small size, long service life, low maintenance costs, reliable operation, and no pollution. The vacuum interrupter mainly uses vacuum to weaken the electric arc. If the interrupter leaks and air enters, the arc extinguishing effect of the interrupter will be greatly weakened.

[0003] Currently, in order to improve the sealing performance of vacuum bubbles during the manufacturing process, a sealing process is carried out. However, the existing vacuum bubble sealing process is mainly manual, that is, the vacuum bubble is placed into the vacuum tank by hand and then pressurized and sealed. This process is inefficient, time-consuming and labor-intensive.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this invention is to provide a self-weight pressure sealing device that automates the vacuum bubble sealing process, thereby improving work efficiency compared to traditional manual operation.

[0006] This utility model provides a self-weight pressure sealing device, including a base, a lifting drive cylinder, a connecting plate, a sealing tank, a worktable, and a sealing fixture; the lifting drive cylinder is connected to the side of the base, and the output end of the lifting drive cylinder is vertically connected to the connecting plate; the lower opening of the sealing tank is connected to the connecting plate, and an inflation connector communicating with the interior of the sealing tank is provided at the upper end of the sealing tank; a worktable is installed on the base, the worktable is located directly below the sealing tank, and the sealing fixture is connected to the middle of the worktable.

[0007] Using the above technical solution, the sealing fixture is a vacuum bubble sealing fixture of the prior art. In use, the inflation connector is connected to an external inflation device. Driven by the lifting drive cylinder, the sealing can is raised, and the cylindrical product (vacuum bubble) is placed in the sealing fixture by the gripper of the robot. At this time, the lifting drive cylinder retracts, the sealing can descends, and the opening of the sealing can is placed on the worktable, achieving a seal between the opening of the sealing can and the worktable. The cylindrical product is located inside the sealing can. The external inflation device fills the sealing can with gas. As the internal gas pressure increases, the fit between the cylindrical product and the sealing fixture increases, thereby achieving sealing using the weight of the product itself.

[0008] Furthermore, the sealed container includes an upper connecting piece, a lower connecting piece, connecting rods, and a sleeve; both the upper and lower connecting pieces are circular, with the lower connecting piece located directly below the upper connecting piece. Four connecting rods are vertically connected to the lower circumference of the upper connecting piece, with a central angle of 90 degrees between adjacent connecting rods. The other end of each connecting rod is connected to the circumference of the lower connecting piece. Annular grooves are provided on both the lower and upper sides of the upper connecting piece, and both ends of the sleeve are sealed and fitted onto the annular grooves.

[0009] Furthermore, the end of the connecting plate is provided with a semi-circular groove, the connecting plate is connected to the lower connecting piece, and the semi-circular groove and the annular groove are fitted together.

[0010] Furthermore, the sealed container also includes a one-way valve, which is connected to one end of the inflation connector located inside the sealed container.

[0011] Furthermore, the self-weight pressure sealing device also includes a telescopic electric cylinder and a mounting plate. The two ends of the bottom of the lifting drive electric cylinder are hinged to the base. The mounting plate is connected to the left and right sides of the upper end of the lifting drive electric cylinder. The other ends of the two mounting plates are hinged to the output end of the telescopic electric cylinder, and the other ends of the two telescopic electric cylinders are hinged to the base.

[0012] The self-weight pressure sealing device provided by this utility model connects the inflation connector to an external inflation device during use. Driven by a lifting drive cylinder, the sealing can rises, and the cylindrical product (vacuum bubble) is gripped by a robotic arm and placed into the sealing fixture. At this time, the lifting drive cylinder retracts, the sealing can descends, and the sealing can is positioned on the worktable, achieving a seal between the opening of the sealing can and the worktable. The cylindrical product is located inside the sealing can. The external inflation device fills the sealing can with gas. As the internal gas pressure increases, the fit between the cylindrical product and the sealing fixture increases, thus achieving sealing using the product's own weight. This automates the vacuum bubble sealing process, improving work efficiency compared to traditional manual operation. Attached Figure Description
