Abstract

The invention discloses an indexable lifting type hydraulic clamping device, and belongs to the technical field of automatic tools and equipment. The indexable lifting type hydraulic clamping device comprises a lifting mechanism and a clamping mechanism which are arranged from bottom to top. The lifting mechanism comprises a lower end cover, a lower cylinder body is arranged outside the lower end cover, and an annular piston is arranged between the lower end cover and the lower cylinder body. The clamping mechanism comprises an upper cylinder body and a double-connecting-rod clamping device, a piston is arranged in the upper cylinder body, an upper end cover is arranged on the upper end face of the upper cylinder body, and a hole penetrating through the double-connecting-rod clamping device is formed in the upper end cover. According to the indexable lifting type hydraulic clamping device, when automatic integrated machining of multiple parts of a part is completed through one-time clamping and the appearance of the part is machined, the end face of the part can be rapidly clamped by lifting the whole mechanism from an inner hole of the part and rotating a pressing arm; and when the end face of the part is machined, the whole mechanism descends and is hidden in the clamp through transposition of the pressing arm, and interference generated during machining is avoided.

Description

technical field [0001] The invention belongs to the technical field of automatic tooling and equipment, and relates to an indexable lifting hydraulic clamping device. Background technique [0002] With the application and development of quick-change tooling in automated production lines, the design requirements for clamping devices in the industrial field are also getting higher and higher. It is required that the clamping device not only meet the multi-functional requirements of machining, but also meet the needs of automation. The clamping device used in the quick-change tooling of the automatic production line of the central gear case casing requires that the parts be clamped reliably, and the appropriate clamping force is given by the hydraulic system without causing deformation of the parts and surface damage. During the processing, the positioning position of the parts does not change. Secondly, the components of the clamping device can be hidden inside the fixture by...
