Detailed Description

The utility model discloses a realize through following technical scheme.

A vacuum compaction clamp comprises a clamp body 1, wherein a cavity for air to flow is formed in the clamp body 1, and a vacuum pressure pump 6 is connected with the cavity in the clamp body 1 through a hose 3; the part is placed in a groove on the top surface of the clamp body 1, the groove on the top of the clamp body 1 is matched with the profile of the bottom surface of the part, and the edge of the part is sealed with the groove through a sealing ring; in this embodiment, sealing rings 7 are provided between the inner and outer sides of the component and the groove. The groove at the top of the fixture body 1 is positioned at the bottom part of the part and is provided with a plurality of vent holes communicated with the cavity of the fixture body 1.

A gas-water separator 5 is also arranged between the vacuum pressure pump 6 and the clamp body 1, and the gas-water separator 5 is respectively connected with the vacuum pressure pump 6 and the clamp body 1 through pipelines.

A three-way valve 2 is arranged at the joint of the hose 3 and the clamp body 1. A connecting pipe nozzle 4 is arranged at the joint of the hose 3 and the gas-water separator 5.

Certain pressure is output through the vacuum pressure pump, enters the cavity of the clamp body 1 through the gas-water separator filter 5 and the three-way valve 2, then enters the groove in the top surface of the clamp body through the vent hole, and because the inner side and the outer side of the part are sealed by the sealing ring 7 with the groove, the air between the bottom of the part and the groove is discharged through the pressure, and vacuum is formed.
