Embodiment Construction

[0023] Universal vacuum suction cup with self-shutoff function is a device for adsorbing and fixing three-dimensional curved surface parts on flexible tooling; it consists of sealing lip suction cup 1, first layer of rotating ball bowl 2, second layer of rotating ball bowl 3, ball The bowl support 4, polyurethane elastic rubber (5), sealing sleeve 11, and the pinhole sliding block 7 and spring 8 installed on the ball bowl support are composed of;

[0024] The suction cup (1) of the sealing lip is made into a concave structure. The lip is made of polyurethane rubber inlaid on the steel core to ensure airtightness and durability during vacuum adsorption, and it is not easy to damage the workpiece. The steel core in the middle is made of There are vent holes and screw holes; the first layer of rotating bowl 2 is made of a concave and outer circle structure, the upper part is matched with the suction cup, and the two are connected as one by screws, and the outer surface is spherica...

Abstract

The invention discloses a universal vacuum chuck with an automatic closing function, which is a device for adsorption fixation of large three-dimensional surface parts. The device mainly comprises a seal lip suction disc (1), a first layer of rotary spherical bowl (2), a second layer of rotary spherical bowl (3) and a spherical bowl supporting seat (4). The structure of the two layers of rotary spherical bowls guarantees that the chuck can swing in the angle range of 45 DEG to adapt to the requirements of adsorption fixation of different three-dimensional surface parts; and meanwhile, a vacuum automatic feedback adjustment device comprising a sliding block with a pin hole on the side wall of the supporting seat, a spring and a dustproof net guarantees that a vacuum air channel is automatically connected for adsorbing the parts when the parts are on the chuck, and after the parts are taken down, only a pin hole air channel on a moving block is connected to achieve the purpose of almost closing the chuck. According to the universal vacuum chuck, the vacuum chuck is integrated with the vacuum feedback adjustment device, so that the vacuum pumping flow quantity in the working and intermittent states can be automatically adjusted, and the function of automatically adsorbing the parts in the presence of the parts and automatically closing the chuck in the absence of the parts is achieved.

Description

Technical field: [0001] The invention is a device for adsorbing and fixing any three-dimensional curved surface parts on a flexible tooling, and belongs to the field of mechanical engineering. Background technique: [0002] In the milling, drilling, scribing and other processing processes of large three-dimensional curved surface parts such as aircraft skins, as well as the riveting and other assembly processes, special tooling and fixtures are required. Each part requires a set of special tooling, which is costly and requires a large storage space. Therefore, a multi-point flexible tooling has appeared, which can automatically arrange the required nail column positions and adjust to the required height according to the size and geometry of the supported parts, replacing traditional special tooling, supporting and fixing large three-dimensional curved surfaces Parts for measuring, scribing, milling, drilling, etc. In order to meet the requirements of a set of tooling to su...
