Clamping device and milling composite machine

Abstract

The invention provides a clamping device and a milling composite machine. The clamping device is fixed on a base of the milling composite machine and used for clamping a rotary table of the milling composite machine; the clamping device comprises a first cushion block, a first support block, a bump, a first clamp plate, a second clamp plate, a bolt, an elastic element, an oil cylinder, a second cushion block, a second support block, a sleeve and a locking element, wherein the first cushion block and the first support block are detachably connected on the base; the bump is fixed on the first cushion block; the bolt is fixed on the first clamp plate and passes through the first clamp plate and the second clamp plate; the elastic element is sleeved on the bolt and propped against the first clamp plate and the second clamp plate; the oil cylinder is sleeved on the bolt; the sleeve is sleeved on the bolt in a sliding manner; the second cushion block and the second support block are detachably connected on the first support block; the second support block supports the sleeve; and the locking element is locked on the bolt and propped against the sleeve.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a clamping device and a turning-milling compound machine tool using the clamping device. Background technique [0002] In recent years, the domestic demand for turning-milling compound machine tools has been increasing day by day, which greatly meets the user's requirements for workpiece processing efficiency and processing automation. The rotary table is the key functional part of the turning-milling compound machine tool. While realizing the linear motion of the machine tool, it completes the rotary indexing of the workpiece, and realizes the processing of each surface of the workpiece in one clamping. The rotary table should be reliably positioned and clamped during workpiece processing. [0003] At present, the domestic positioning and locking methods of the rotary worktable mainly include the steel ball rod locking type, the internal clamping type of the worktable center, and t...

AI Technical Summary

Problems solved by technology

However, although the steel ball tie rod locking type and the internal clamping type in the center of the worktable can lock the rotary worktable, the clamping force is relatively small and the reliability is poor.
